||PCT/SE2014/050910||TELEFONAKTIEBOLAGET L M ERICSSON (PUBL) ||GODANA, Bruhtesfa |
There is provided a method, performed by a communication station, for Listen-Before-Talk, LBT, based medium access. The method comprises the step (S1) of performing an LBT-based medium access procedure including sensing a radio-based medium on a shared radio spectrum during a sensing duration, deferring transmission if an on-going transmission is detected during the sensing, and transmitting on the radio-based medium if no on-going transmission is detected during the sensing. The method further comprises the step (S2) of waiting, when the communication station has transmitted, for a waiting duration that is based on a time duration between consecutive sensing occasions for at least one other communication station, also operating according to an LBT-based medium access procedure on the shared radio spectrum, before performing the LBT-based medium access procedure again.

||PCT/SE2014/050912||TELEFONAKTIEBOLAGET L M ERICSSON (PUBL) ||ROELAND, Dinand |
The present disclosure relates to a method performed in a source gateway 33a which is logically positioned in a first wireless access network 32 between a radio device 31 and a first mobility anchor 37. The source gateway comprises a Multipath Transmission Control Protocol (MPTCP) proxy 34 for a TCP flow 30 between the radio device and a peer 39. The TCP flow comprises at least two subflows between the radio device and the source gateway. The subflows comprises a first subflow 30a over the first wireless access network and a second subflow 30b over a second wireless access network 35. The method comprises receiving uplink data of the second subflow from a second gateway 36c logically positioned in the second wireless access network between the radio device and a second mobility anchor 37, and sending downlink data of the second subflow to said second gateway. The method also comprises moving the proxy from the source gateway to a target gateway 33b logically positioned in the first wireless access network between the radio device and the first mobility anchor, as part of a handover of the radio device within the first wireless access network. The method also comprises, after having moved the proxy to the target gateway, forwarding downlink data of both the first and second subflows to the target gateway, and forwarding the received uplink data of the second subflow to the target gateway.
WO/2016/018181 AUTOMATED FLOW DEVOLVEMENT IN AN AGGREGATE FLOW ENVIRONMENT||WO||04.02.2016|
||PCT/SE2014/050909||TELEFONAKTIEBOLAGET L M ERICSSON (PUBL) ||JOHN, Wolfgang |
Mechanisms for devolving microflows from aggregate flows are disclosed. An ingress node receives a packet that matches an aggregate flow entry in a flow table. A determination that a devolve action is associated with the aggregate flow entry is made. Based on the determination that the devolve action is associated with the aggregate flow entry, a microflow flow entry is generated in the flow table to define a microflow. The microflow flow entry includes header information extracted from the packet. Microflow generation information that identifies the microflow is sent to a controller node. It is determined that the microflow has timed out based on an idle timeout period of time. In response to determining that the microflow has timed out, microflow termination information that includes path measurement metric information associated with the microflow is sent to the controller node.
WO/2016/018185 PYRAMID VECTOR QUANTIZER SHAPE SEARCH||WO||04.02.2016|
||PCT/SE2015/050743||TELEFONAKTIEBOLAGET L M ERICSSON (PUBL) ||SVEDBERG, Jonas |
An encoder and a method therein for Pyramid Vector Quantizer, PVQ, shape search, the PVQ taking a target vector x as input and deriving a vector y by iteratively adding unit pulses in an inner dimension search loop. The method comprises, before entering a next inner dimension search loop for unit pulse addition, determining, based on the maximum pulse amplitude, maxampy, of a current vector y, whether more than a current bit word length is needed to represent enloopy, in a lossless manner in the upcoming inner dimension loop. The variable enloopy is related to an accumulated energy of the vector y. The performing of this method enables the encoder to keep the complexity of the search at a reasonable level. For example, it enables the encoder to apply an increased precision loop only when it may be needed, by analyzing whether the "worst case scenario" in the upcoming inner loop would require an inner loop with a higher precision than the one currently used.

WO/2016/018188 METHODS FOR ADAPTING OVER-THE-AIR SYNCHRONIZATION TO RADIO CONDITIONS||WO||04.02.2016|
||PCT/SE2015/050836||TELEFONAKTIEBOLAGET L M ERICSSON (PUBL) ||CENTONZA, Angelo |
Methods for enabling and disabling of muting patterns in Radio Access Network, RAN, nodes allow better detection and use of reference symbols used for synchronization. In some embodiments, coordination of muting patterns amongst different nodes is enabled, so that muting of multiple nodes results in increased protection from interference for the node in need of detecting the synchronization reference symbols. An example method is implemented in a base station operating in a wireless communications network, for facilitating over-the-air synchronization by a neighboring base station. This method includes receiving (1210) a request for activation of a reference signal muting pattern for a cell supported by the base station and activating (1220) the reference signal muting pattern in response to the request. The method further includes sending (1225) a message requesting activation of a reference signal muting pattern for a cell supported by a second base station, in response to the request.
