Abstract: A computer-implemented method for operating in a reduced power mode (RPM) of a user equipment (UE) in communications with a base station pursusant to a normal power mode (NPM). The NPM is characterized by one or more normal-power parameters comprising a normal sampling frequency and a normal signal bandwidth. The RPM is characterized by one or more reduced-power parameters comprising a reduced sampling frequency or a partial signal bandwidth. The UE determines whether to enter into the RPM for a duration. In response to determining to enter into the RPM for the duration, the UE powers down into the RPM by operating with the one or more reduced-power parameters for the duration of the RPM. Upon expiry of the duration of the RPM by the UE, the UE powers up into the NPM by resuming to the sampling frequency of the NPM and the signal bandwidth of the NPM.

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: 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.
