Abstract: Apparatus, methods, and computer-readable media for facilitating CSI feedback in multiple-TRP communication are disclosed herein. An example method of wireless communication by a UE includes receiving, from a base station, a report configuration message triggering a channel state feedback procedure, the UE and the base station operating in a multiple transmission and reception point (multiple-TRP) communication mode, the report configuration message requesting a multiple-TRP transmission value including at least one of a quantity of layer indicator (LI) values and a strongest TRP indicator (STI) value. The example method also includes generating channel state information (CSI) information based on the receiving of the report configuration message, the CSI information including the multiple-TRP transmission value. The example method also includes transmitting, to the base station, a report including the generated CSI information.

Abstract: Aspects of the disclosure relate to control of discovery signal transmissions for D2D communication. A first UE may transmit a discovery signal initiation message to at least a second UE to control transmission of a discovery signal from the second UE to a third UE. The second UE may identify a discovery signal monitoring duration of the second UE during which the second UE monitors for transmitted discovery signals transmitted from other UEs to the third UE. At expiration of the discovery signal monitoring duration, the second UE may transmit a discovery signal to the third UE when the number of transmitted discovery signals transmitted from the other UEs during the discovery signal monitoring duration is less than a discovery signal transmission number threshold.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may send, and a user equipment (UE) may receive, a transmission beam adjustment message indicating a change from a first time interval to a second time interval in which a transmission beam is utilized to transmit a synchronization signal and physical broadcasting channel block (SSB). The base station may send the transmission beam adjustment message to all connected UEs, individual UEs affected by the adjustment, or to one or more UE groups. The UE may receive the transmission beam adjustment message and determine a new time interval of the transmission beam pattern that the base station is using the transmission beam to transmit the SSB. The UE may monitor the new time interval for the SSB using a receive beam that corresponds to the transmission beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may transmit, to a parent node of the IAB node, full-duplex (FD) information based at least in part on a transmit power value for an FD mode. The IAB node may receive an FD resource allocation for the IAB node, wherein the FD resource allocation identifies a resource to be used for a first communication link with the parent node and a second communication link in the FD mode, and wherein the FD resource allocation is based at least in part on the FD information. The IAB node may communicate on the first communication link and the second communication link in accordance with the FD resource allocation. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may identify a sounding reference signal (SRS) resource associated with an uplink precoding resource block group of a physical uplink shared channel (PUSCH) resource. The user equipment may precode a portion of a PUSCH communication, to be transmitted in the uplink precoding resource block group, based at least in part on the identified SRS resource. The user equipment may transmit the PUSCH communication after precoding the PUSCH communication. Numerous other aspects are provided.

Abstract: Apparatus, methods, processing systems, and computer readable mediums for beam management in multi-TRP scenarios are disclosed. An exemplary method generally includes receiving a channel state information reference signal (CSI-RS) resource configuration from at least one base station (BS) for one or more transmission hypotheses, wherein the CSI-RS resource configuration includes CSI-RS resources corresponding to at least a first downlink (DL) demodulation reference signal (DMRS)-port-group and a second DL DMRS-port-group, performing one or more CSI-RS measurements for the one or more transmission hypotheses based, at least in part on the CSI-RS resource configuration, and determining, for each of the one or more transmission hypotheses, a preferred reception beam for communicating with the at least one BS based, at least in part, on the one or more CSI-RS measurements.

Abstract: In conventional wireless communication systems, only a single transmit precoding matrix indicator (TPMI) with a single associated sounding reference signal (SRS) resource indicator (SRI) is configured/activated in downlink control signal (DCI) for retransmission of data. To enable better performance in retransmission, the UE may dynamically turn on/off/switch panels for retransmissions.
