Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may report basis subset selection for a set of beams, where the basis vectors are used for frequency domain compression. To reduce reporting overhead, the UE may transmit two reports indicating the basis vectors. The first report may include first information for the basis vectors and is of a known payload size to both the UE and a base station, while the second report may include second information for the basis vectors and may have a payload size dependent on the first information. The base station may decode the first report and may use the decoded first information to decode the second report. Based on the first and second information, the base station may determine the reported set of basis vectors to use for frequency domain compression and may determine non-zero precoding coefficients.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for providing quasi-colocation (QCL) signaling for reference signals (RS) and channels across scenarios involving multiple cells, such as coordinated multipoint (CoMP) scenarios in which multiple transmit receive points (TRPs) or integrated access and backhaul (IAB) nodes each have their own cell ID.

Abstract: Certain aspects of the present disclosure provide techniques for uplink sounding reference signal (SRS) transmission with precoding. A method for wireless communication by a user equipment (UE) includes receiving a SRS configuration that configures one or more SRS resource sets, each resource set including one or more SRS resources, each SRS resource comprising one or more SRS ports. The UE receives a set of precoders via an indicator, the set of precoders including a precoder associated with each SRS resource and determines one or more precoders to apply for one or more SRS transmissions via one or more of the SRS resources.

Abstract: A base station may determine co-phase information and uplink precoding information (e.g., user equipment (UE) precoder information) based on one or more received sounding reference signals (SRSs) from a UE. The UE may adjust precoders or co-phase for different SRS transmissions over the one or more configured SRS resources. As such, the base station may indicate either co-phase information or uplink precoding information via an SRS resource indicator (SRI), and may transmit an explicit indication of the remaining co-phase information or uplink precoding information in addition to the SRI. In other examples (e.g., when only a single SRS resource is configured), the base station may transmit an index corresponding to uplink precoding information, as well as a separate indication of co-phase information. In some cases, a port selection pattern may be included with an explicit indication, indicating a selection of antenna port indices the precoder or co-phase index applies to.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that one or more measurement reference resources, of a plurality of measurement reference resources, are preempted; and, based at least in part on the determination, selectively: cancel transmission of a measurement report, or transmit the measurement report based at least in part on at least a portion of the plurality of measurement reference resources. In some aspects, the UE may determine that one or more uplink reference signal resources, of a plurality of uplink reference signal resources, are to be preempted; and, based at least in part on the determination, selectively: cancel transmission of an uplink reference signal, or transmit the uplink reference signal based at least in part on at least a portion of the plurality of uplink reference signal resources. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to UCI layer mapping. According to certain aspects, a mapping rule maps UCI to one or more layers of a physical uplink shared channel (PUSCH) transmission based on at least one of a rank of the PUSCH transmission or a modulation and coding scheme (MCS) of the PUSCH transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more reference signals from a plurality of transmit receive points (TRPs) associated with a network entity. The UE may transmit, to the network entity and based at least in part on the one or more reference signals, a coherent joint transmission (CJT) Type II channel state information (CSI) feedback report. The CJT Type II CSI feedback report may be based at least in part on a two-stage frequency domain (FD) basis reporting irrespective of a quantity of precoding matrix indicator (PMI) subbands. The CJT Type II CSI feedback report may be based at least in part on selecting coefficients from high-priority coefficients and excluding low-priority coefficients irrespective of coefficient strengths associated with the low-priority coefficients. Numerous other aspects are described.
