reconfiguration request. Using one reconfiguration message now induces the UE transmits data 30 times earlier than using two reconfiguration messages.

At step 1b, the UE checks the presence of such an indication. If this indication is not present, the UE assumes SPS is configured as legacy behaviour. If this indication is present, the UE checks its value. Accordingly, on receipt of the RRC reconfiguration the UE knows that radio resources for uplink transmission without grant are configures if a Layer1 signalling activation is included. If this indication is set to ON (YES), the UE waits for Layer1 signalling before performing uplink data transmission by the UE has to reading and decoding the Layer1 signalling (DCI format) including Layer1 parameters. This is shown in Steps 2 and 3. If the indication is set to OFF (NO), the UE waits immediately perform uplink data transmission according to configured Layer1 parameters part of RRC message in Step 1. This is shown in Step 3.

Figure 6 illustrates an embodiment where the new indication is included in the RRC configuration message along with SPS parameters. This embodiment can be used in the scenario where uplink transmission without grant is changed to SPS configuration and vice versa.

At steps 0 and 0a, SPS configuration is set towards the RRC_Connected UE. The SPS RNTI is specific to the UE to identify data between the UE and the network. At step 1 , the UE is moved to RRCJnactive where one or multiple UEs can share the radio resources for data transmission. Consequently, at step 2, uplink transmission without grant Type 2 reconfiguration is set towards the UE. At step 2a, the new uplink transmission without grant configuration RNTI is used to identify data between the UEs and the network. The RNTI can be alternatively included in System Information signalling, in which case the uplink transmission without grant configuration is inferred by the UE based on the new Layer1 signalling activation follow-up indicator. The checking of any indicator is performed in a similar manner to that described above with reference to Figure 5.

If the indicator is set to "OFF" value is set, then the UE can straightforwardly perform UL grant transmission according to configured Layer1 parameters part of RRC message in Step 2a. If the indicator is set to "ON" a value is set, then the UE has to read and decode the Layer1 signalling (DCI format) including Layer1 parameters before performing the uplink transmission.

At step 2b, upon receipt of the RRC configurations the UE knows from the presence of uplink transmission without grant RNTI that uplink transmission without grant is configuration. The indicated RNTI will be used by the UE to encode the data further sent on the PUSCH. If Layer1 signalling activation follow up indication is used and set to ON the UE has to wait for Layer1 signalling activation before performing the uplink transmission. Some RNTI values can be dedicated to UL transmission without grant Type 1 , while other RNTI values can be dedicated to UL transmission without grant Type 2. The advantage is to save signalling overhead by implicit indication of the Layer1 signalling activation follow-up indicator. Actually based on RNTI values specific to UL transmission without grant Type 1 , the UE knows that it should not read and decode the Layer1 signalling (DCI format) including Layer1 parameters before performing the uplink transmission. Conversely, based on RNTI values specific to UL transmission without grant Type 2, the UE knows that it should read and decode the Layer1 signalling (DCI format) including Layer1 parameters before performing the uplink transmission.

The present invention this solves many of the problems associated with prior art methods for controlling the activation of physical layer signalling by higher layer signalling. The invention may be used as described above or may include any variations which would be clear to the person skilled in the art. For example, the invention may apply to any context where layeM signalling information is used, particularly, but not only, before data is transmitted.

Although not shown in detail any of the devices or apparatus that form part of the network may include at least a processor, a storage unit and a communications interface, wherein the processor unit, storage unit, and communications interface are configured to perform the method of any aspect of the present invention. Further options and choices are described below.

The signal processing functionality of the embodiments of the invention especially the gNB and the UE may be achieved using computing systems or architectures known to those who are skilled in the relevant art. Computing systems such as, a desktop, laptop or notebook computer, hand-held computing device (PDA, cell phone, palmtop, etc.), mainframe, server, client, or any other type of special or general purpose computing device as may be desirable or appropriate for a given application or environment can be used. The computing system can include one or more processors

which can be implemented using a general or special-purpose processing engine such as, for example, a microprocessor, microcontroller or other control module.

The computing system can also include a main memory, such as random access memory (RAM) or other dynamic memory, for storing information and instructions to be executed by a processor. Such a main memory also may be used for storing temporary variables or other intermediate information during execution of instructions to be executed by the processor. The computing system may likewise include a read only memory (ROM) or other static storage device for storing static information and instructions for a processor.

The computing system may also include an information storage system which may include, for example, a media drive and a removable storage interface. The media drive may include a drive or other mechanism to support fixed or removable storage media, such as a hard disk drive, a floppy disk drive, a magnetic tape drive, an optical disk drive, a compact disc (CD) or digital video drive (DVD) read or write drive (R or RW), or other removable or fixed media drive. Storage media may include, for example, a hard disk, floppy disk, magnetic tape, optical disk, CD or DVD, or other fixed or removable medium that is read by and written to by media drive. The storage media may include a computer-readable storage medium having particular computer software or data stored therein.

In alternative embodiments, an information storage system may include other similar components for allowing computer programs or other instructions or data to be loaded into the computing system. Such components may include, for example, a removable storage unit and an interface , such as a program cartridge and cartridge interface, a removable memory (for example, a flash memory or other removable memory module) and memory slot, and other removable storage units and interfaces that allow software and data to be transferred from the removable storage unit to computing system.

The computing system can also include a communications interface. Such a communications interface can be used to allow software and data to be transferred between a computing system and external devices. Examples of communications interfaces can include a modem, a network interface (such as an Ethernet or other NIC card), a communications port (such as for example, a universal serial bus (USB) port), a PCMCIA slot and card, etc. Software and data transferred via a communications interface are in the form of signals which can be electronic, electromagnetic, and optical or other signals capable of being received by a communications interface medium.

In this document, the terms 'computer program product', 'computer-readable medium' and the like may be used generally to refer to tangible media such as, for example, a memory, storage device, or storage unit. These and other forms of computer-readable media may store one or more instructions for use by the processor comprising the computer system to cause the processor to perform specified operations. Such instructions, generally referred to as 'computer program code' (which may be grouped in the form of computer programs or other groupings), when executed, enable the computing system to perform functions of embodiments of the present invention. Note that the code may directly cause a processor to perform specified operations, be compiled to do so, and/or be combined with other software, hardware, and/or firmware elements (e.g., libraries for performing standard functions) to do so.

The non-transitory computer readable medium may comprise at least one from a group consisting of: a hard disk, a CD-ROM, an optical storage device, a magnetic storage device, a Read Only Memory, a Programmable Read Only Memory, an Erasable Programmable Read Only Memory, EPROM, an Electrically Erasable Programmable Read Only Memory and a Flash memory

In an embodiment where the elements are implemented using software, the software may be stored in a computer-readable medium and loaded into computing system using, for example, removable storage drive. A control module (in this example, software instructions or executable computer program code), when executed by the processor in the computer system, causes a processor to perform the functions of the invention as described herein.

Furthermore, the inventive concept can be applied to any circuit for performing signal processing functionality within a network element. It is further envisaged that, for example, a semiconductor manufacturer may employ the inventive concept in a design of a stand-alone device, such as a microcontroller of a digital signal processor (DSP), or application-specific integrated circuit (ASIC) and/or any other sub-system element.

It will be appreciated that, for clarity purposes, the above description has described embodiments of the invention with reference to a single processing logic. However, the inventive concept may equally be implemented by way of a plurality of different functional units and processors to provide the signal processing functionality. Thus, references to specific functional units are only to be seen as references to suitable means for providing the described functionality, rather than indicative of a strict logical or physical structure or organisation.

Aspects of the invention may be implemented in any suitable form including hardware, software, firmware or any combination of these. The invention may optionally be implemented, at least partly, as computer software running on one or more data processors and/or digital signal processors or configurable module components such as FPGA devices. Thus, the elements and components of an embodiment of the invention may be physically, functionally and logically implemented in any suitable way. Indeed, the functionality may be implemented in a single unit, in a plurality of units or as part of other functional units.

Although the present invention has been described in connection with some embodiments, it is not intended to be limited to the specific form set forth herein. Rather, the scope of the present invention is limited only by the accompanying claims. Additionally, although a feature may appear to be described in connection with particular embodiments, one skilled in the art would recognize that various features of the described embodiments may be combined in accordance with the invention. In the claims, the term 'comprising' does not exclude the presence of other elements or steps.

Furthermore, although individually listed, a plurality of means, elements or method steps may be implemented by, for example, a single unit or processor. Additionally, although individual features may be included in different claims, these may possibly be advantageously combined, and the inclusion in different claims does not imply that a combination of features is not feasible and/or advantageous. Also, the inclusion of a feature in one category of claims does not imply a limitation to this category, but rather indicates that the feature is equally applicable to other claim categories, as appropriate.

Furthermore, the order of features in the claims does not imply any specific order in which the features must be performed and in particular the order of individual steps in a method claim does not imply that the steps must be performed in this order. Rather, the steps may be performed in any suitable order. In addition, singular references do not exclude a plurality. Thus, references to 'a', 'an', first', 'second', etc. do not preclude a plurality.

Although the present invention has been described in connection with some embodiments, it is not intended to be limited to the specific form set forth herein. Rather, the scope of the present invention is limited only by the accompanying claims. Additionally, although a feature may appear to be described in connection with particular embodiments, one skilled in the art would recognise that various features of the described embodiments may be combined in accordance with the invention. In the claims, the term 'comprising' or "including" does not exclude the presence of other elements.
