Abstract: Apparatus, methods, and computer program products for beam updating are provided. An example method includes receiving DCI. The method further includes determining, based on the DCI, whether the DCI is associated with a beam update for uplink, downlink, or a combination of the uplink and the downlink. The method further includes determining, from the DCI, a TCI state that indicates a beam for the uplink, the downlink, or the combination of the uplink and the downlink.

Abstract: The method of wireless communication may include a relay user equipment (UE) and a target UE. The relay UE may receive, from a base station, a paging relay request message including a paging message for the target UE, the paging relay request message requesting the relay UE to transmit the paging message to the target UE, and transmit a sidelink control information (SCI) type 1 (SCI-1) and/or an SCI type 2 (SCI-2) and the paging message to the target UE through one or more sidelink channels based on the received paging relay request message. The target UE may decode the paging message received from the relay UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication of at least one first beam and at least one first antenna panel of the UE, to use for one or more first transmissions, and of at least one second beam and at least one second antenna panel of the UE, to use for one or more second transmissions. Accordingly, the UE may communicate the one or more first transmissions, with the base station, using the at least one first beam and the at least one first antenna panel. Additionally, the UE may communicate the one or more second transmissions, with the base station, using the at least one second beam and the at least one second antenna panel. Numerous other aspects are provided.

Abstract: Aspects presented herein may improve the performance and/or efficiency of a BFD procedure for a UE, where the UE may use DMRS to perform the BFD to reduce the occasion(s) of configuring multiple or frequent CSI-RS resources sets for the UE. In one aspect, an apparatus measures RSRP of one or more reference signals in a reference signal set for a BFD, the one or more reference signals include at least one DMRS. Then the apparatus compares the measurement for the at least one DMRS to a threshold. Then the apparatus initiates or restarts a BFD timer or a BFR procedure based at least in part on the measurement.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques that allow for paging UEs with updates to system information for cells that support physical (PHY) or medium access control (MAC) layer mobility. An example method generally includes receiving one or more signals configuring the UE with a set of cells that support physical (PHY) layer or medium access control (MAC) layer mobility, receiving paging message including an indication that an update to system information is available, and communicating with one or more of the set of cells based on the updated system information.

Abstract: A method of wireless communication, by a first sidelink user equipment (UE), includes periodically receiving a set of sidelink beam failure detection reference signals (RSs) from a second sidelink UE. The method includes incrementing a beam failure detection (BFD) counter in response to one or more reference signals of the set of sidelink beam failure detection RSs having a received signal strength below a threshold. The first sidelink UE starts a beam failure detection timer in response to the reference signal(s) of the set of sidelink beam failure detection reference signals having the received signal strength below the threshold. Another method by a sidelink UE may periodically transmit a set of sidelink BFD RSs to another sidelink UE. The set of sidelink BFD RSs comprise one or more sidelink receive RSs. The sidelink UE configures the other sidelink UE with the sidelink receive BFD RSs.

Abstract: A method of wireless communication by a first sidelink user equipment (UE) transmits a sidelink (SL) beam failure recovery (BFR) message to a communications node, indicating a new candidate beam and an identifier (ID) of a second sidelink UE. The method also receives an acknowledgment of the SL BFR message. A communications node receives a sidelink beam failure recovery message from a first sidelink user equipment, indicating a new candidate beam and an ID of a second sidelink UE. The method also transmits information identifying the new candidate beam and the ID to the second sidelink UE. Another method by a first sidelink user equipment receives a sidelink beam failure recovery message from a base station, indicating a new candidate beam and an ID of a second sidelink UE. The method changes a beam used to communicate with the second sidelink UE in response to receiving the BFR message.

Abstract: A base station may transmit a beam refinement reference signal prior to a paging physical downlink control channel (PDCCH) monitoring occasion to improve reception of a paging downlink control information (DCI). A user equipment (UE) may receive at least one transmission indicating the beam refinement reference signal transmitted prior to the PDCCH monitoring occasion. The UE may receive the beam refinement reference signal prior to the paging PDCCH monitoring occasion based on the at least one transmission. The UE may receive a downlink control information on the paging PDCCH monitoring occasion based on the beam refinement reference signal.

Abstract: Certain aspects of the present disclosure provide techniques for paging in a wireless communication system. A method that may be performed by a base station (BS) generally includes determining one or more groups of UEs, each group of UEs comprising UEs configured to monitor a same paging occasion (PO) for a same paging radio network temporary identifier (PRNTI). The BS determines whether to postpone paging for a group of UEs based, at least in part, on an indication from a network entity of priorities associated with the UEs in the group. The method generally includes paging or postponing paging for at least one of the UEs in the group based on the determination.
