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: 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: A computer-implemented method includes sending, by an access node, to a user equipment (UE) configuration information for a beam quality reference signal (BQRS) that is associated with a discontinuous reception (DRX)-ON period used for sending a physical downlink control channel (PDCCH) to the UE, wherein the BQRS has a spatial quasi-collocated (QCL) relationship with either the PDCCH or a demodulation reference signal (DMRS) of the PDCCH. The method further includes sending, by the access node, the BQRS to the UE.

IPC: H04W52/02
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.
