WIRELESS DEVICE, NETWORK NODE, AND METHODS PERFORMED THEREBY FOR HANDLING MEASUREMENTS ON A SET OF CELLS

TECHNICAL FIELD

The present disclosure relates generally to a wireless device and methods performed thereby for for handling measurements by the wireless device on a set of cells. The present disclosure further relates generally to a network node, and methods performed thereby for for handling the measurements by the wireless device on the set of cells.

BACKGROUND

Communication devices within a wireless communications network may be wireless devices such as e.g., User Equipments (UEs), stations (STAs), mobile terminals, wireless terminals, terminals, and/or Mobile Stations (MS). Wireless devices are enabled to communicate wirelessly in a cellular communications network or wireless communication network, sometimes also referred to as a cellular radio system, cellular system, or cellular network. The communication may be performed e.g., between two wireless devices, between a wireless device and a regular telephone, and/or between a wireless device and a server via a Radio Access Network (RAN), and possibly one or more core networks, comprised within the wireless communications network. Wireless devices may further be referred to as mobile telephones, cellular telephones, laptops, or tablets with wireless capability, just to mention some further examples. The wireless devices in the present context may be, for example, portable, pocket-storable, hand-held, computer-comprised, or vehicle-mounted mobile devices, enabled to communicate voice and/or data, via the RAN, with another entity, such as another terminal or a server.

Communication devices may also be network nodes, such as radio network nodes, e.g., Transmission Points (TP). The wireless communications network covers a geographical area which may be divided into cell areas, each cell area being served by a network node such as a Base Station (BS), e.g., a Radio Base Station (RBS), which sometimes may be referred to as e.g., gNB, evolved Node B ("eNB"), "eNodeB", "NodeB", "B node", or BTS (Base Transceiver Station), depending on the technology and terminology used. The base stations may be of different classes such as e.g., Wide Area Base Stations, Medium Range Base Stations, Local Area Base Stations and Home Base Stations, based on transmission power and thereby also cell size. A cell is the

geographical area where radio coverage is provided by the base station at a base station site. One base station, situated on the base station site, may serve one or several cells. Further, each base station may support one or several communication technologies. The wireless communications network may also be a non-cellular system, comprising network nodes which may serve receiving nodes, such as wireless devices, with serving beams. In 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE), base stations, which may be referred to as eNodeBs or even eNBs, may be directly connected to one or more core networks. In the context of this disclosure, the expression Downlink (DL) may be used for the transmission path from the base station to the wireless device. The expression Uplink (UL) may be used for the transmission path in the opposite direction i.e. , from the wireless device to the base station.

In a wireless communications system, such as a cellular network, a wireless device, e.g. , a wireless device, may be monitoring the surrounding radio environment, by performing measurements of signals from different cells, e.g. , by monitoring different signal strengths from different cells, which may be from different radio base stations or from different cells served by the same base station. The stronger the signal strength from the cell is, the more suitable is the cell to camp on. By frequently monitoring the surrounding radio environment, the wireless device may be ensured to be camping on the cell serving the wireless device with the strongest signal strength, or at least one of the stronger cells, given its current position.

In LTE, a measurement configuration, MeasConfig, may be provided to the UE that may be understood to provide the necessary information to the UE for performing measurements. The MeasConfig provided to the U E may inform the UE of, amongst other things, the measurement objects, reporting configuration, and quantity

configuration. The measurement object may be understood to refer to a frequency or carrier that is to be measured and the relevant information that may be required for performing measurements in that frequency or carrier, for example, which cells to be measured in the said frequency, which cells are not to be measured in the said frequency, what is the cell individual offset to be used, etc.. The reporting configuration may be understood to define to a condition to be met for the measurement result to be reported, and the quantity configuration may be understood to refer to how to filter the measurement quantities, e.g. , Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SI NR), specific filtering coefficients, etc...

The MeasConfig
LTE RRC, according to 3GPP spec. 36.331 is as follows:


The UE may be configured with multiple measurement objects, wherein each may correspond to the carrier associated with that measurement object. In the Carrier Aggregation (CA) or Dual Connectivity (DC) case, the UE may be configured with one PCell and possibly one or more SCells. The UE may be required to perform the measurements in these corresponding frequencies.

In LTE, only one Reference Signal (RS) type may be used to derive cell quality or cell measurement results. Hence, upon receiving a measurement configuration, the UE may be required to perform cell measurement results for the PCell and the configured SCells based on the cell-specific RS in those configured frequencies. Therefore, for all these serving cells, the UE may use the same RS type, namely the cell-specific RS.

NR architecture

The so-called 5G system, from a radio perspective started to be standardized in 3GPP and the so-called New Radio (NR) is the name for the radio interface. One of the characteristics of NR is the frequency range going to higher frequencies than LTE, e.g., above 6 GHz, where it is known to have more challenging propagation conditions such as a higher penetration loss. To mitigate some of these effects, multi-antenna technologies such as beamforming may be massively used. Yet another NR characteristic is the possibility to enable shorter latencies.

NR architecture is being discussed in 3GPP, where gNB denotes a NR BS. One NR BS may correspond to one or more transmission/reception points. Both standalone and non-standalone NR deployments will be standardized in 3GPP. The standalone deployments may be single or multi-carrier, e.g., NR CA or dual connectivity with NR PCell and NR PSCell. The non-standalone deployments are currently meant to describe a deployment with LTE PCell and NR PSCell. There may also be one or more LTE SCells and one or more NR SCell.

Currently, there are no existing configurations on how to perform serving cell related measurements in NR.

SUMMARY

It is an object of embodiments herein to enable the handling of cell measurements by a wireless device in NR.

According to a first aspect of embodiments herein, the object is achieved by a method, performed by a wireless device. The method is for handling measurements by the wireless device on a set of cells comprising at least a first cell. The cells in the set are serving cells. The wireless device operates in a wireless communications network. The wireless device determines one or more types of signals to perform measurements on for each cell in the set of cells. The determination is based on an obtained

configuration, per configured event, of one or more events. Each of the one or more events sets a condition to trigger a measurement report. At least one of the one or more events is configured in at least one reportConfig. The reportConfig is linked to a measurement object whose Reference Signal (RS) Type within the reportConfig is set to one type of signal of the one or more types of signals. The wireless device determines to perform the measurements on at least the one type of signal that is set. The wireless device then initiates sending an indication to a network node serving the wireless device. The indication is based on the measurements by the wireless device on the determined one or more types of signals.

According to a second aspect of embodiments herein, the object is achieved by a method, performed by the network node. The method is for handling the measurements by the wireless device on the set of cells comprising at least the first cell. The cells in the set are serving cells. The network node and the wireless device operate in the wireless communications network. The network node provides the first indication to the wireless device. The first indication comprises the configuration, per configured event, of the one or more events. Each of the one or more events sets a condition to trigger a

measurement report. At least one of the one or more events is configured in at least one reportConfig. The reportConfig is linked to the measurement object whose RS Type within the reportConfig is set to one type of signal of one or more types of signals to perform measurements on. The network node then obtains, based on the provided first indication, the second indication from the wireless device. The second indication is based on the measurements, by the wireless device, on the at least the one type of signal that is set within the reportConfig.

According to a third aspect of embodiments herein, the object is achieved by the wireless device, configured to handle measurements by the wireless device on the set of cells configured to comprise at least the first cell. The cells in the set are configured to be serving cells. The wireless device is configured to operate in the wireless

communications network. The wireless device is further configured to determine the one or more types of signals to perform measurements on for each cell in the set of cells. To determine is configured to be based on the configuration configured to be obtained, per configured event, of the one or more events. Each of the one or more events is configured to set a condition to trigger a measurement report. At least one of the one or more events is configured in at least one reportConfig. The reportConfig is configured to be linked to the measurement object whose RS Type within the reportConfig is configured to be set to one type of signal of the one or more types of signals. The wireless device is configured to determine to perform the measurements on at least the one type of signal that is configured to be set. The wireless device is further configured to initiate sending the indication to the network node configured to serve the wireless device. The indication is configured to be based on the measurements by the wireless device on the one or more types of signals configured to be determined.

According to a fourth aspect of embodiments herein, the object is achieved by the network node, configured to handle the measurements by the wireless device on the set of cells configured to comprise at least the first cell. The cells in the set are configured to be serving cells. The network node and the wireless device are configured to operate in the wireless communications network. The network node is further configured to provide the first indication to the wireless device. The first indication is configured to comprise the configuration, per configured event, of the one or more events. Each of the one or more events is configured to set a condition to trigger a measurement report. At least one of the one or more events is configured in at least one reportConfig. The reportConfig is configured to be linked to the measurement object whose RS Type within the reportConfig is configured to be set to one type of signal of one or more types of signals to perform measurements on. The network node is also configured to obtain, based on the first indication configured to be provided, the second indication from the wireless device. The second indication is configured to be based on the measurements, by the wireless device, on the at least the one type of signal that is configured to be set within the reportConfig.

By the wireless device determining the one or more types of signals to perform measurements on for each of the cells in the set of cells, being based on the obtained configuration per configured event, an already existing RS Type may be used by the network node to indicate which RS Type may be used to perform serving cell

measurements. Therefore, the configuration, when more than one RS may be used is enabled. Furthermore, the configuration procedure is simplified, saving processing, energy, and radio resources for both, the network node and the wireless device.

Furthermore, the measurement report may contain the quality of the cells in the set of cells, e.g., SCells, based on different types of signals, e.g., RS signals. By then initiating sending the indication to the network node, the network may be enabled to evaluate the quality of the cells based on both different signals, before, e.g., establishing a dual connectivity or carrier aggregation. This may be particularly useful when, for example, the different types of signals may be beamformed signals, and they may be beamformed differently. One of the types of signals may be coverage oriented, e.g., more wide beams with uniform coverage, and another type of signal may be capacity oriented, e.g., more narrow beams but with spotty coverage. If the network node obtains the SCell quality based on both these types of signals, it may be enabled to better judge whether a particular cell, e.g., a SCell, may be suitable for the wireless device or not.

DETAILED DESCRIPTION

As part of the development of embodiments herein, one or more problems with the existing technology will first be identified and discussed.

In NR, the cell measurement results, e.g. , Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), may be computed based on different RS Types, e.g., NR Synchronization Signal (NR-SS) or Channel State Information RS (CSI-RS), where the measurement quantities to be included may be configured per reportConfig.

Agreements from RAN2#97 meeting

1 An RRC_CONNECTED UE should be able to perform Radio Resource Management (RRM) measurements on always on IDLE RS, e.g., synchronization signal.

An RRC_CONNECTED UEs should be able to perform RRM

measurements on additional RS, e.g., CSI-RS, Mobility Reference Signal (MRS), etc..

It has also been agreed that the PCell and SCell measurements may always be included in the measurement report.

Agreements from RAN2#98AH meeting

5: For event triggered reporting:

PCell and SCells cell quality are always included in the measurement report

The PCell and SCells may be transmitting both NR-SS and CSI-RS. In such a scenario, although it has been agreed that the UE may perform serving cell

measurements and report different measurement quantities as configured in

reportConfig, it has not been discussed in 3GPP how to configure the RS, or the UE, to perform serving cell related measurements, e.g., PCell and SCells.

In order to address these problems, several embodiments are comprised herein. As a summarized overview, embodiments herein may be understood to relate to

configuration of measurement of a serving cells in NR. Particular examples of

embodiments herein may be understood to relate to a method where the network may configure the UE to perform cell level measurements associated with the PCell and the configured SCell(s), e.g., in the case of carrier aggregation, based on the same or different reference signal types (RS types).

The RS types may be a RS in the SS Block, such as NR-PSS, and/or NR- Secondary Synchronization Signal (SSS), and/or Physical Broadcast CHannel (PBCH) DeModulation Reference Signal (DRMS) or the CSI-RS(s).

In an alternative approach, the UE may perform cell level measurements related to all configured RSs per SCell and PCell.

Embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which examples are shown. In this section, the embodiments herein will be illustrated in more detail by a number of exemplary embodiments. It should be noted that the exemplary embodiments herein are not mutually exclusive. Components from one embodiment may be tacitly assumed to be present in another embodiment and it will be obvious to a person skilled in the art how those components may be used in the other exemplary embodiments.

Note that although terminology from 5G NR has been used in this disclosure to exemplify the embodiments herein, this should not be seen as limiting the scope of the embodiments herein to only the aforementioned system. Other wireless systems with similar features, may also benefit from exploiting the ideas covered within this disclosure.

Figure 1 depicts two non-limiting examples, in Figure 1 a, and 1 b respectively, of a wireless communications network 100, sometimes also referred to as a wireless communications system, cellular radio system, or cellular network, in which embodiments herein may be implemented. The wireless communications network 100 may typically be a 5G system, 5G network, or Next Gen System or network. The wireless communications network 100 may also support other technologies such as, for example, Long-Term Evolution (LTE), e.g. LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), LTE Half-Duplex Frequency Division Duplex (HD-FDD), LTE operating in an unlicensed band, Wideband Code Division Multiple Access (WCDMA), Universal

Terrestrial Radio Access (UTRA) TDD, Global System for Mobile communications (GSM) network, GSM/Enhanced Data Rate for GSM Evolution (EDGE) Radio Access Network (GERAN) network, Ultra-Mobile Broadband (UMB), EDGE network, network comprising of any combination of Radio Access Technologies (RATs) such as e.g. Multi-Standard Radio (MSR) base stations, multi-RAT base stations etc., any 3rd Generation Partnership Project (3GPP) cellular network, WiFi networks, Worldwide Interoperability for Microwave Access (WMax), or any cellular network or system. Thus, although terminology from 5G/NR may be used in this disclosure to exemplify embodiments herein, this should not be seen as limiting the scope of the embodiments herein to only the aforementioned system. The wireless communications network may also be understood as a non-cellular system, comprising network nodes which may serve receiving nodes, such as wireless devices, with serving beams. This may be a typical case, e.g., a in a 5G network.

The wireless communications network 100 comprises a plurality of network nodes, whereof a network node 110 is depicted in the non-limiting examples of Figure 1. In other examples, which are not depicted in Figure 1 , the network node 110 may be a distributed node, such as a virtual node in the cloud, and may perform its functions entirely on the cloud, or partially, in collaboration with a radio network node.

The network node 110 may be a radio network node. That is, a transmission point such as a radio base station, for example a gNB, or any other network node with similar features capable of serving a wireless device, such as a user equipment or a machine type communication device, in the wireless communications network 100.

The wireless communications network 100 covers a geographical area which may be divided into cell areas, wherein each cell area may be served by a network node, 5 although, one radio network node may serve one or several cells. The wireless

communications network 100 comprises a set of cells. The set of cells comprises a first cell 121 , and may further comprise, in some embodiments, one or more second cells 122. In the non-limiting example depicted in Figure 1 , only one second cell 122 is depicted to simplify the Figure. However, it will be understood that more second cells 10 may be comprised in the one or more second cells 122. The first cell maybe a primary cell (PCell) and each of the one or more second cells 122 may be a secondary cell (SCell). In the non-limiting example depicted in Figure 1 ,

the network node 110 is a radio network node that serves the first cell 121 , and the one or more second cells 122. However, in other examples, any of the one or more second cells

15 122 may be served by other network nodes in the wireless communications network 100.

Even in examples wherein the wireless communications network 100 may not be referred to as a cellular system, if the network node 1 10 may serve receiving nodes, such as wireless devices, with serving beams, the areas of coverage of the beams may still be referred to as cells. The network node 1 10 may be of different classes, such as, e.g.,

20 macro base station, home base station or pico base station, based on transmission power and thereby also cell size. The network node 1 10 may support one or several communication technologies, and its name may depend on the technology and terminology used. In 5G/NR, the network node 1 10 may be referred to as a gNB and may be directly connected to one or more core networks, which are not depicted in Figure 1.

25 A plurality of wireless devices are located in the wireless communication network 100, whereof a wireless device 130, is depicted in the non-limiting examples of Figure 1. The wireless device 130 comprised in the wireless communications network 100 may be a wireless communication device such as a 5G UE, or a UE, which may also be known as e.g., mobile terminal, wireless terminal and/or mobile station, a mobile telephone, cellular

30 telephone, or laptop with wireless capability, just to mention some further examples. Any of the wireless devices comprised in the wireless communications network 100 may be, for example, portable, pocket-storable, hand-held, computer-comprised, or a vehicle- mounted mobile device, enabled to communicate voice and/or data, via the RAN, with another entity, such as a server, a laptop, a Personal Digital Assistant (PDA), or a tablet

35 computer, sometimes referred to as a tablet with wireless capability, Machine-to-Machine (M2M) device, device equipped with a wireless interface, such as a printer or a file storage device, modem, or any other radio network unit capable of communicating over a radio link in a communications system. The wireless device 130 comprised in the wireless communications network 100 is enabled to communicate wirelessly in the 5 wireless communications network 100. The communication may be performed e.g., via a RAN, and possibly the one or more core networks, which may comprised within the wireless communications network 100.

The wireless device 130 may be configured to communicate within the wireless communications network 100 with the network node 1 10 in the first cell 121 over a first

10 link 141 , e.g., a radio link. The wireless device 130 may be configured to communicate within the wireless communications network 100 with the network node 110 in each of the one or more second cells 122 over a respective second link 142, e.g., a radio link.

In some embodiments, the wireless communications network 100 may be connected to a host computer 150, which is depicted in the example of Figure 1 b. The

15 host computer 150 may be embodied in the hardware and/or software of a standalone server, a cloud-implemented server, a distributed server or as processing resources in a server farm. The host computer 150 may be under the ownership or control of a service provider, or may be operated by the service provider or on behalf of the service provider. The host computer 150 may communicate with the wireless device 130 via a third link

20 160. The third link 160 may comprise one or more wired and wireless links, and extend via, e.g., the cloud 170, the network node 110, and other network nodes or core network nodes in the wireless communications network. In some examples, the third link 160 may extend via an optional intermediate network, which is not depicted in Figure 1 to simplify the Figure. The intermediate network may be one of, or a combination of more than one

25 of, a public, private or hosted network; the intermediate network may be a backbone

network or the Internet. A connectivity provided by the third link 160 may be referred to as an Over the Top (OTT) connection.

The system comprising the host computer 150, the network node 1 10 and the wireless device 130 may be referred to herein as a telecommunications system 180.

30 In general, the usage of "first", "second", "third", "fourth", "fifth" and/or "sixth" herein may be understood to be an arbitrary way to denote different elements or entities, and may be understood to not confer a cumulative or chronological character to the nouns they modify.

Terminology

The term "radio measurement" used herein may refer to any measurement performed on radio signals. Radio measurements may be absolute or relative. Radio measurement may be referred to as a signal level, which may be a signal quality and/or a signal strength. Radio measurements may be e.g., intra-frequency, inter-frequency, inter-RAT measurements, Carrier Aggregation (CA) measurements, etc. Radio measurements may be unidirectional, e.g., DL or UL, or bidirectional, e.g., Round-Trip Time (RTT), Reception-Transmission (Rx-Tx), etc... Some examples of radio

measurements may be timing measurements, such as e.g., Time of Arrival (TOA), timing advance, RTT, Reference Signal Time Difference (RSTD), Rx-Tx, propagation delay, etc., angle measurements, such as e.g., angle of arrival, power-based measurements, such as e.g., received signal power, RSRP, received signal quality, RSRQ, SINR, Signal to Noise Ratio (SNR), interference power, total interference plus noise, Received Signal Strength Indicator (RSSI), noise power, etc., cell detection or cell identification, Radio Link Monitoring (RLM), System Information (SI) reading, etc. The inter-frequency and inter-RAT measurements may be carried out by the UE in measurement gaps unless the UE may be capable of doing such measurement without gaps. Examples of measurement gaps are measurement gap id # 0, each gap of 6 ms occurring every 40 ms, measurement gap id # 1 , each gap of 6 ms occurring every 80 ms, etc. The measurement gaps may be configured at the UE by the network node.

Performing a measurement on a cell may imply performing measurements on signals of the cell. Examples of cell specific measurements may be signal strength, signal quality etc.

Embodiments of a method, performed by the wireless device 130, will now be described with reference to the flowchart depicted in Figure 2. The method is for handling measurements by the wireless device 130 on a set of cells comprising at least the first cell 121. The cells in the set may be understood to be serving cells.

In some embodiments, the set of cells may further comprise one or more second cells 122. In some of these embodiments, the first cell 121 may be a primary cell (PCell) and the one or more second cells 122 may be secondary cells (SCell).

The wireless device 130 operates in the wireless communication network 100. In some embodiments all the actions may be performed. In some embodiments, an action may be optional. It should be noted that the examples herein are not mutually exclusive. One or more embodiments may be combined, where applicable. Components

from one embodiment may be tacitly assumed to be present in another embodiment and it will be obvious to a person skilled in the art how those components may be used in the other exemplary embodiments. All possible combinations are not described to simplify the description. In Figure 2, an optional actions is indicated with dashed lines. Some actions may be performed in a different order than that shown in Figure 2.

Action 201

In the course of its operations in the wireless communications network 100, the wireless device 130, may monitor the surrounding radio environment to e.g., make sure it is camping on the cell serving with the strongest signal strength, given its current position. As stated above, in NR, the cell measurement results may be computed based on different RS Types. In NR, it has been agreed that cell measurements results may either be configured by the network to be performed based on SS Block-based reference signal(s) (e.g. NR-SSS) or CSI-RS.

Based on a previous agreement, different events, such as A1 , A2, etc.. may be configured with different RS Type(s). Hence, for example, some events may be

configured based on CSI-RS, while other events may be configured based on SS-Block signal(s). In another example, the same event type, e.g., A1 , may be linked to the same measurement object but, thanks to different measurement IDs, one may be configured for SS-based while the other for CSI-RS.

In order to enable the wireless device 130 to determine on which RS, out of the possible RS Types, to perform serving cell related measurements, in this Action 201 , the wireless device 130 may obtain a first indication from the network node 110. In some particular examples, the wireless device 130 may be a 5G UE and the network node 1 10 may be an gNB.

Obtaining may be understood as e.g., receiving. The receiving in this Action 201 may be implemented, e.g., via the first link 141.

The obtained configuration may be obtained, per configured event, of one or more events. Each of the one or more events may be understood to set a condition to trigger a measurement report. The one or more events may be e.g., A1 , A2, A3, A4, etc...

The first indication may comprise a configuration. The first indication may for example be, an information element in MeasConfig.

In some embodiments, the obtained configuration may be a reportConfig.

At least one of the one or more events may be configured in at least one

reportConfig linked to a measurement object whose Reference Signal (RS) Type within

the reportConfig is set to one type of signal to perform measurements on for each cell in the set of cells.

The type of signal may comprise: an RS in the SS Block, such as NR-PSS and/or NR-SSS and/or PBCH DRMS, or the CSI-RSs.

Action 202

In this Action 202, the wireless device 130, determines one or more types of signals to perform measurements on for each cell in the set of cells. The determination is based on the obtained configuration, per configured event, of the one or more events. That is, the configuration obtained in Action 201. As stated earlier, each of the one or more events sets a condition to trigger a measurement report. At least one of the one or more events is configured in at least one reportConfig linked to a measurement object whose RS Type within the reportConfig is set to one type of signal of the one or more types of signals. The wireless device 130 determines to perform the measurements on at least the one type of signal that is set.

In some embodiments, the obtained configuration may be the reportConfig, which is used for the determination in this Action 202.

The one or more types of signals in the configuration may be understood as a first group of one or more types of signals.

The determined one or more types of signals may be understood as a second group of one or more types of signals.

That is, the wireless device 130 may determine in this Action 202 to perform the first cell 121 measurements based on the SS.

In a second option, the measurement object is associated to the first cell 121 , and is linked to the at least one reportConfig, whose RS Type is set to CSI-RS. According to such second option, the wireless device 130 performs first cell 121 measurements based on the CSI-RS. That is, the wireless device 130 may determine in this Action 202 to perform the first cell 121 measurements based on the CSI-RS.

The determination may be based on one or more default types of signals to perform measurements on for at least one of the cells in the set of cells, in case of at least one of: 20 a) an absence of the obtained configuration by the wireless device 130; and b) the

The one or more default types of signals may be understood as a third group of one or more types of signals.

25 O Initiating 203 sending the indication to a network node, e.g., the network node 110, serving the wireless device 130, the indication being based on the

measurements by the wireless device 130 on the determined one or more types.

In such embodiments, the method may further comprise the action of:

o Obtaining 201 the first indication from the network node 110, the first

30 indication comprising the configuration.

The network node 1 10 examples relate to Figure 3, Figure 6, Figure 7 and Figure 9. A method, performed by the network node 110 may comprise one or more of the following actions. The method may be for handling measurements by the wireless device 35 130 on the set of cells. The set of cells may comprise the first cell 121 and the one or more second cells 122. The set of cells may be configured for usage by the wireless device 130. The network node 110 and the wireless device 130 may be operating in the wireless communications network 100.

o Providing 301 the first indication to the wireless device 130, the first indication comprising the configuration for the one or more types of signals to perform measurements on at least one of the cells in the set of cells.

o Obtaining 302 the second indication from the wireless device 130. The second indication may be based on the measurements by the wireless device 130 based on the provided first indication.

The indication may be for example comprised in, e.g., measResults.

The provided configuration may comprise the one or more types for less than all of the cells in the set of cells.

The configuration in the provided first indication may be per configured event of one or more events, wherein each of the one or more events may set a condition to trigger a measurement or measurement report.

The first indication may be an information element in MeasConfig.

The first cell 121 may be a primary cell PCell and the one or more second cells 122 may be secondary cell SCell.

The one or more types of signals may comprise: an RS in the SS Block, such as NR-PSS and/or NR-SSS and/or PBCH DRMS or the CSI-RSs.

By the wireless device determining the one or more types of signals to perform measurements on for each of the cells in the set of cells, being based on whether or not the configuration for the one or more types of signals for each of the cells in the set of cells has been obtained, the measurement report may contain the quality of the cells in the set of cells, e.g., SCells, based on different types of signals, e.g., RS signals. By then initiating sending the indication to the network node, the network may be enabled to evaluate the quality of the cells based on both different signals, before establishing a dual connectivity or carrier aggregation. This may be particularly useful when, for example, the different types of signals may be beamformed signals, and the may be beamformed differently. One of the types of signals may be coverage oriented , e.g., more wide beams with uniform coverage, and another type of signal may be capacity oriented, e.g., more narrow beams but with spotty coverage. If the network node 110 obtains the SCell quality based on both these types of signals, it may be enabled to better judge whether a particular cell, e.g., a SCell, may be suitable for the wireless device 130 or not.

Particular examples of the examples related to the embodiments herein will now be described. In the following description, any reference to a/the UE may be understood to relate to the wireless device 130, and any reference to a/the network node may be understood to relate to the network node 110.

In a first related example, the wireless device 130 performs cell measurements based on all possible reference signals, for example, SS and CSI-RS, for each serving cell, i.e., for the PCell and the configured SCells. In that example, for NR, if the UE has configured K SCells per mandated trigger quantity, e.g., RSRP and RSRQ, the UE may, or may be required to or may be configured to, perform cell measurement results for the PCell and each SCell based on both the SS Block and CSI-RS. In other words, the UE may perform for the PCell:

- PCell RSRP measurement result based on SS Block;

- PCell RSRP measurement result based on CSI-RS;

- PCell RSRQ measurement result based on SS Block;

- PCell RSRQ measurement result based on CSI-RS;

And for each configured SCell(k), for k=1 , ... ,K:

- SCell(k) RSRP measurement result based on SS Block;

- SCell(k) RSRP measurement result based on CSI-RS;

- SCell(k) RSRQ measurement result based on SS Block;

- SCell(k) RSRQ measurement result based on CSI-RS;

One possible UE action related to that related example may occur if the network may only have provided CSI-RS configuration associated to a subset of the serving cells, i.e., PCell and/or a subset of the configured SCells. In that case, in one approach, the UE may use the SS Block to perform cell measurement results. In another solution, the UE may notify the network of a failure, e.g., by indicating in an existing message or in a new message defined for that purpose.

In a second related example, the UE may have a single default RS type(s) for the

PCell measurement results. In one approach in that related example, if no specific configuration for PCell RS Type may have been provided, or for the frequency and/or measurement object associated to that cell, the RS type may be set by the UE to SS Block. In another solution, if no configuration for PCell RS Type is provided, the RS type may be set by the UE to CSI-RS. In the case of CSI-RS as being default, the UE may still use the SS Block if a CSI-RS related configuration for the PCell has not been provided.

In a third example, the UE may have a single default RS type(s) for the SCell measurement results. In one approach in that example, if no specific configuration for SCell RS Type is provided, or for the frequency and/or measurement object associated to that cell, the RS type may be set by the UE to SS Block. In another approach, if no configuration for SCell RS Type is provided, the RS type may be set by the UE to CSI-RS. In the case of CSI-RS as being default, the UE may still use the SS Block if a CSI-RS related configuration for the SCell has not been provided.

In a third related example, the UE may be configured with the RS type to be used for serving cell measurements as part of the MeasObject, which may be one or a

combination of the following alternatives:

- Serving cell RS Type PCell (pCellRSType): Regardless if the MeasObjectNR is linked to a measurement identifier or not, the configured information may be used by the UE to interpret that the UE may perform PCell measurement results based on that RS Type. That may be in NR SS Block or CSI-RS. Based on the configured events linked to Measurement Objects (MOs), the UE may realize that the same RS type is used is all events requiring PCell measurements or, in the case that at least one event that requires PCell measurement results as trigger condition uses an RS Type different from the one provided in the measurement object, the UE may perform additional measurement results for the PCell based on that other RS Type.

Serving cell RS Type SCell (sCellRSType): Regardless if the MeasObjectNR is linked to a measurement identifier or not, the configured information may be used by the UE to interpret that the UE may perform SCell measurement results based on that RS Type for the configured SCell associated to the same frequency of that same MeasObjectNR. That may be an NR SS Block or CSI-RS. Based on the configured events linked to MOs, the UE may realize that the same RS type is used is all events requiring SCell measurements or, in the case that at least one event that requires SCell measurement results as trigger condition uses an RS Type different from the one provided in the measurement object, the UE may perform additional measurement results for the SCell based on that other RS Type.

In a fourth related example, the UE may be configured with the RS type to be used for serving cell measurements as part of the MeasConfig, which may be one or a combination of the following alternatives:

Serving cell RS Type PCell (pCellRSType): There may be an IE defined in measConfig that indicates that the UE may perform PCell measurement results based on that RS Type. That may be in NR SS Block or CSI-RS. Based on the configured events linked to configured MOs, the UE may realize that the same RS type is used is all events requiring PCell measurements or, in the case that at least one event that may require PCell measurement results as trigger condition uses an RS Type different from the one provided in the measurement object, the UE may perform additional measurement results for the PCell based on that other RS Type.

Serving cell RS Type SCell (sCellRSType): There may be an IE defined in measConfig that indicates that the UE may perform all SCell measurement results based on that configured RS Type(s). That may be in NR SS Block or

CSI-RS. Based on the configured events linked to MOs, the UE may realize that the same RS type is used is all events requiring SCell measurements or, in the case that at least one event that requires SCell measurement results as trigger condition uses an RS Type different from the one provided in the measurement object, the UE may perform additional measurement results for the SCell based on that other RS Type.

MeasConfig information element


It may be noticed that although it has been mentioned that an RS Type is selected, that may be one RS Type, SS Block or CSI-RS, or both RS Type, e.g., SS Block AND CSI-RS.

When the UE may be measuring the serving cell, that is, PCell or SCell, based on the SS only and when the measurement report may be triggered, the sent measurement report may include the serving cell level quality based on SSBs only. The UE may also include the beam based results based on the SSBs for the cells included in the measurement report.

When the UE may be measuring the serving cell, that is, PCell or SCell, based on the CSI-RS only and when the measurement report may be triggered, the sent measurement report may include the serving cell level quality based on CSI-RSs only. The UE may also include the beam based results based on the CSI-RSs for the cells included in the measurement report.

When the UE may be measuring the serving cell, that is, PCell or SCell, based on both the SS and CSI-RS and when the measurement report may be triggered, the sent measurement report may include the serving cell level quality based on SSBs and the serving cell quality based on CSI-RSs. The UE may also include the beam based results based on the SSBs and CSI-RSs for the cells included in the measurement report.
