Abstract: Embodiments of this disclosure provide techniques for signaling in power save mode. In particular, a UE may identify an association between a set of time durations for paging a downlink control indicator (DCI) transmission and a wake up signal (WUS) in a set of WUSs. Paging the DCI is transmitted in a beam sweeping manner and each beam used in each time duration in the set of time durations corresponds to a respective beam used for a WUS transmission in the set of WUSs. The UE monitors a radio link quality of WUSs in the set of WUSs and, based thereon, selects a first WUS in the set of WUSs. The UE identifies a first time duration for DCI page monitoring, the first time duration corresponding to the first WUS. The UE monitors the DCI page during the first time duration.

Abstract: A method for measuring beams includes determining a measurement period duration in accordance with periods of one or more periodic beam failure detection (BFD) reference signals (RSs) of a BFD RS set, wherein the BFD RSs of the one or more BFD RSs of the BFD RS set have a quasi-co-located (QCL) relationship with demodulation RSs (DMRSs) of PDCCH receptions monitored by a user equipment (UE), monitoring a subset of the one or more BFD RSs having the QCL relationship with the DMRSs of PDCCH receptions monitored by the UE that occur during a measurement period, and determining that measures of all BFD RSs in the subset of the one or more BFD RSs do not meet a specified threshold, and based thereon, reporting a beam failure (BF) instance.

Abstract: A method implemented by an access node includes transmitting, by the access node, a wake up signal (WUS) prior to a control channel occurring within an associated discontinuous reception (DRX) ON period, wherein the WUS is transmitted using a first beam, and transmitting, by the access node, the control channel during the associated DRX ON period, wherein the control channel is transmitted on a control resource set (CORESET) using a second beam, wherein the first and second beams share a common quasi-colocated (QCL) source.

Abstract: A computer-implemented method for transmission beam control in a data communication by an electronic device includes scheduling a periodic data transmission to a second electronic device on a first resource using at least a first beam and a second beam during a first time period. The electronic device transmits data, through a sidelink between the electronic device and the second electronic device, to the second electronic device on the first resource using at least the first beam and the second beam during the first time period.

Abstract: A cell search method and a communications apparatus are provided. The method includes the following: before searching for a cell, a terminal device may determine, with reference to historical access information of another terminal device, whether there is a cell at the location, and adjust, based on a determining result, a value of a search parameter used to search for a cell. For example, if there is a cell, the terminal device may adjust the search parameter to accelerate a search. If there is no cell, the terminal device may perform no search, or adjust the search parameter to reduce an unnecessary cell search performed by the terminal device, so that power consumption of the terminal device can be reduced.

Abstract: Embodiments of this disclosure provide techniques for communicating in a wireless communications system. In particular, in an embodiment a base station receives a capability message from a user equipment (UE) indicating downlink scheduling delay. The base station transmits a downlink control frame to the UE in response to determining that transmitting a frame to the UE satisfies a scheduling delay condition. The downlink control frame indicates a scheduling delay of the frame equal to or greater than the downlink scheduling delay. The base station then transmits the frame to the UE in accordance with the downlink control frame.

Abstract: Embodiments of the present disclosure provide an apparatus and method for beam failure recovery between a UE and a base station operating in a discontinuous reception (DRX) mode. In an embodiment, the UE receives a frame from a base station for determining a radio link quality of a physical downlink control channel (PDCCH). The UE determines whether the frame is received only during the DRX ON state of the DRX mode and that the radio link quality of the PDCCH is less than an acceptable quality threshold. In response, the UE transmits a recovery message to the base station indicating a change to a communication beam used to receive the frame.
