Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for sidelink discovery message forwarding. In some implementations, a first user equipment (UE) may receive a discovery message from a second UE. The discovery message may be part of a beam training procedure between the first UE and the second UE. The first UE may forward the discovery message to one or more other UEs based on a condition associated with one or more forwarding termination parameters being satisfied. The first UE may, in some implementations, select one of a broadcast transmission or a unicast transmission for forwarding the discovery message based on one or more parameters associated with the UE. The first UE may transmit the discovery message from the second UE to the one or more other UEs using the selected broadcast or unicast transmission when the condition is satisfied.

Abstract: Methods, systems, and devices for wireless communication are described related to timer-based sidelink discontinuous reception (DRX). A UE may receive configuration information for a sidelink DRX mode from a base station or another UE, which may indicate one or more parameters of the sidelink DRX mode. When operating in the sidelink DRX mode, a group of UEs may have shared active durations and inactive durations for coordinating sidelink communications. In a timer-based sidelink DRX mode, if a UE receives or transmits a sidelink communication, the UE may initiate an inactivity timer, and the UE may continue to monitor a sidelink channel for other sidelink communications while the timer is running. One or more rules may govern the operation of an inactivity timer with respect to the shared inactive durations.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device may receive control signaling indicating a sidelink beam failure reporting configuration including a set of sidelink beam failure reporting events. The communication device may identify occurrence of a sidelink beam failure reporting event, and may transmit a beam measurement report to another communication device over a sidelink in accordance with the sidelink beam failure reporting configuration. The transmission of the beam measurement report may be triggered based on the sidelink beam failure reporting event.

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.

Abstract: Methods, systems, and devices for wireless communications are described. Wireless devices may be configured to support techniques for bi-directional discontinuous reception (DRX) alignment and centralized DRX alignment. In the context of bi-directional DRX alignment, DRX configurations at two respective user equipments (UEs) are first established in a first direction, and then DRX configurations are then established in the reverse direction based on the previously-established DRX configurations. In particular, DRX configurations in the reverse direction may be selected such that the Uu and sidelink DRX configurations are aligned at the respective UEs and across the UEs. Comparatively, in the context of centralized DRX alignment, a master base station receives “candidate” Uu and sidelink DRX configurations for multiple UEs, and selects Uu and sidelink DRX configurations for each UE from the sets of candidate DRX configurations in order to ensure DRX alignment across the respective UEs.

Abstract: Disclosed are techniques for wireless communication. In an aspect, an originator UE transmits a sidelink beam training (BT) reference signal (BTRS) a first number of times on each of a first set of beams, and a sidelink discovery message a second number of times on each of a second set of beams, wherein each beam from the second set of beams is associated with at least one beam from the first set of beams (e.g., 1:1 or N:1 mapping of first set of beams to second set of beams). At least one responder UE responds by transmitting, after the transmission of the sidelink BTRSs and the sidelink discovery messages, a BT response signal and a sidelink discovery response message on a beam corresponding to one of the first set of beams.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) (e.g., Tx UE) may transmit or receive a first control message indicating a sidelink beam measurement configuration for performing a sidelink beam sweep procedure using a set of transmit beams. The first UE may select a subset of transmit beams from the set of transmit beams for the sidelink beam sweep procedure based on one or more parameters associated with the sidelink beam measurement configuration. The first UE may then transmit, to a second UE (e.g., Rx UE) during the sidelink beam sweep procedure, a set of sidelink reference signals using respective transmit beams of the subset of transmit beams.

Abstract: An apparatus includes one or more transmitters configured to transmit, from a first user equipment (UE) to a second UE, a sidelink discontinuous reception (DRX) setup request indicating a first DRX configuration of the first UE. The apparatus further includes one or more receivers configured to receive, from the second UE, a sidelink DRX setup response based on the sidelink DRX setup request and indicating a second DRX configuration. The one or more transmitters are further configured to transmit, to a first base station, an uplink message indicating the second DRX configuration, and the one or more receivers are further configured to receive, from the first base station, a downlink message indicating one or more adjusted parameters of the first DRX configuration that are based at least in part on the second DRX configuration.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE (e.g., an initiator UE) transmits sidelink discovery messages for beam training on a bandwidth associated with DMRS. One or more UEs (e.g., candidate responder UEs) select a beam to pair with a beam associated with one of the sidelink discovery messages, and transmit a sidelink discovery message on the selected beam. In another aspect, a UE (e.g., initiator UE) transmits a sidelink discovery message, which is forwarded to a UE, which may be a lead UE of a sidelink UE group. The lead UE adds the initiator UE to the sidelink UE group, and responds with a sidelink discovery response message and a group indication that at least indicates that the initiator UE now belongs to the sidelink UE group.
