    Abstract: This disclosure provides systems, methods and apparatus, including computer storage media for communication between a base station with two transmit receive point (TRPs) and a UE based on a single DCI. The UE receives a single downlink control information (DCI) for the UE that is configured with a first unified transmission configuration indication (TCI) state for a first TRP and second unified TCI state for a second TRP. The DCI includes at least a first TCI field. The UE updates a configuration of at least one of the first unified TCI state to a first updated unified TCI state or the second unified TCI state to a second updated unified TCI state based on the at least one TCI field. The UE communicates with at least one of the first TRP or the second TRP based on the first updated unified TCI state or the second updated unified TCI state.

    Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication, including techniques for sidelink resource allocation and communication. In some aspects, a user equipment (UE) may receive from a base station a single message that indicates a first transmission opportunity for transmission of information from the UE to a second UE and that indicates one or more additional transmission opportunities for at least one subsequent transmission of information from the UE to the second UE. The UE may transmit the information to the second UE in the first transmission opportunity. The UE may also retransmit the information to the second UE in at least one of the one or more additional transmission opportunities responsive to the transmission of the information in the first transmission opportunity being unsuccessful. Other aspects and features are also claimed and described.

    Abstract: Methods, systems, and devices for wireless communications are described in which sidelink communications between devices may be retransmitted using one or more nodes. A first user equipment (UE) may transmit a broadcast, multicast, or groupcast communication to a set of other UEs using sidelink resources. A node may monitor the communications and store the first UE transmission. UEs of the set of other UEs may transmit feedback reports to the node that indicate one or more missing packets of the first UE transmission. The node may retransmit one or more of the stored packets to the set of other UEs based on the feedback reports. In some cases, the sidelink communications may be encoded using a network coding algorithm, and the node may retransmit network coded packets based on the feedback reports, may transmit newly encoded packets based on the feedback reports, or combinations thereof.

    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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may generate a signal for a set of synchronization signal blocks (SSBs) for an SSB burst set, wherein the set of SSBs are associated with a set of analog beamforming configurations associated with a set of spatial directions. The base station may transmit the signal for the set of SSBs using the set of analog beamforming configurations over the set of spatial directions. The base station may receive one or more random access channel (RACH) communications corresponding to one or more SSBs of the set of SSBs in accordance with one or more frequency domain beam sweeping configurations corresponding to one or more analog beamforming configurations of the set of analog beamforming configurations. Numerous other aspects are described.
