Abstract: Certain aspects of the present disclosure provide techniques for channel state information (CSI) reporting with time domain (TD) compression. A method that may be performed by a user equipment (UE) includes receiving one or more CSI-RS from a base station (BS). The UE measures the one or more CSI-RS. The UE determining a mapping order for placing CSI feedback in one or more CSI reports and sends the one or more CSI reports to the BS based on the measurements, the one or more CSI reports providing TD compressed CSI feedback including at least linear combination coefficients associated with TD bases used for the TD compression.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station over a first bandwidth part (BWP) of a carrier. The UE may receive a beam failure recovery (BFR) configuration signal configuring a set of periodic channel state information reference signals (CSI-RSs) in the first BWP and a set of synchronization signals in a second BWP. The UE may measure the set of periodic CSI-RSs in the first BWP. The UE may set a beam for communicating with the base station over the first BWP based at least in part on the measuring. The UE may be a reduced bandwidth capability and support communicating with the base station using only one BWP.

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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that an enhanced type-II channel state information (CSI) report configuration, associated with transmitting CSI feedback to a base station, is to be overridden; and transmit, based at least in part on determining that the enhanced type-II CSI report configuration is to be overridden, a CSI report using another CSI report configuration, wherein the CSI report includes the CSI feedback and an indication that the enhanced type-II CSI report configuration has been overridden. Numerous other aspects are provided.
