摘要： A method, in a network in which a handover of a wireless device occurs, the User Equipment (UE) moving from a source cell to a target cell, is provided. The method comprises at least: (at the source cell) determining a sequence number (SN) related to a data packet; forwarding at the RLC layer data packets to the target cell, the data packets being previously sent to the UE but unacknowledged by the UE and having SNs inferior to the determined sequence number; and sending the determined SN to the target cell. The method further comprises (at the target cell) sending a first data packet with the determined SN to the wireless device; the determined SN being a demarcation line for using different encryption keys. The UE will decrypt the received data packets having SNs inferior to the determined SN using an encryption key from the source cell; and decrypt received packets having SNs superior to the determined SN using an encryption key from the target cell.

摘要： Systems and methods for enhanced link adaptation are provided. In some embodiments, a method of operation of a network node includes calculating an actual RE efficiency based at least in part on an actual TBS obtained from a specification. The TBS may be obtained from a specification based on LA result and actual buffer data volume. The method also includes determining a real BLER from a searchable repository, based on the actual RE efficiency and an actual BLER. The method may further include calculating an actual outer-loop adjustment (OLA) step based on the actual BLER. The method may further include a dynamic outer-loop up/down step adjustment based on the actual OLA step.

摘要： The present disclosure provides a method and time synchronization node for enabling extended holdover time. The method comprises: detecting whether the TS node loses time synchronization with its master TS node or not; and transmitting a first announce message comprising a first indicator to one or more slave TS nodes in response to detecting that the TS node loses the time synchronization with its master TS node, wherein the first indicator indicates a holdover time budget for enabling extended holdover time at the one or more slave TS nodes.

摘要： A method used in a BS for scheduling a UE, and an associated BS is disclosed. The method includes: allocating one or more DL Resource Blocks (RBs) for transmitting DownLink (DL) data to the UE (S910); determining an UpLink (UL) control channel position for the UE transmitting a Hybrid Automatic Repeat Request (HARQ) feedback of the DL data, based on the allocated one or more DL RBs (S920); and transmitting the DL data to the UE by using the allocated one or more DL RBs (S930). Said method also relates to a method used in a UE for transmitting a HARQ feedback, and an associated UE.

摘要： Techniques are provided to determine the status of a radio resource control (RRC) connection between a base station and a mobile terminal in a wireless communication system. According to some aspects, a base station transmits a first message to the mobile terminal, the first message comprising instructions which, upon being executed by the mobile terminal, would cause the establishment, the modification, or the release of the RRC connection between the mobile terminal and the base station. The base station subsequently transmits a second message to the mobile terminal, the second message comprising instructions which, upon being executed by the mobile terminal, would force the mobile terminal to transmit a response to the base station. The base station then determines the status of the RRC connection between the mobile terminal and the base station based, at least in part, on the presence or absence of the response from the mobile terminal.
