摘要： Certain aspects of the present disclosure provide techniques for signaling quasi-coloration (QCL) information for demodulation reference signals (DM-RS) associated with multiple transmission-reception points (multi-TRP). An example method generally includes generating quasi-colocation (QCL) information indicating a first QCL assumption for a first group of demodulation reference signal (DM-RS) ports and a second QCL assumption for a second group of DM-RS ports; and transmitting the QCL information to at least one user equipment (UE) for use in processing one or more transmission associated with at least one of the first group of DM-RS ports and the second group of DM-RS ports.

摘要： Certain aspects of the present disclosure provide techniques for a channel state information (CSI) report configuration for a multiple transmission reception point (TRP) transmission, such as a non-coherent joint transmission (NCJT). A method by a base station (BS) includes providing a user equipment (UE) with a CSI report configuration. The CSI report configuration is associated with one or more CSI reference signal (RS) resources. Each CSI-RS resource comprising a set of ports or port groups. The BS signals the UE to enable the UE to send a CSI report including CSI for more than one CSI-RS resource or for a CSI-RS resource comprising more than one port group and receives a CSI report from the UE.

摘要： Certain aspects of the present disclosure provide techniques for a channel state information (CSI) report configuration with a codebook list, for example, for non-coherent joint transmission (NCJT). A method for wireless communication that can be performed by a user equipment (UE) includes receiving a CSI report configuration. The CSI report configuration is associated with one or more CSI reference signal (RS) resources. Each CSI-RS resource includes a set of ports or port groups. The UE receives a list of codebooks associated with the configuration. The UE determines at least one codebook, from the list of codebooks, to apply for one or more triggered CSI-RS resources.

摘要： Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may transmit sounding reference signals (SRS) to a network entity, receive information indicating at least one of a set of one or more frequency domain (FD) bases and linear combination coefficients, determined based on the SRS transmission, determine subband precoding based at least in part on linear combinations of the FD bases based on the linear combination coefficients, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information for an uplink control channel, wherein the configuration information includes at least one of: a first resource identifier associated with a non-full-duplex (non-FD) zone, or a second resource identifier associated with a full-duplex (FD) zone. The UE may transmit uplink control information (UCI) on the uplink control channel in at least one of the non-FD zone or the FD zone in accordance with the configuration information. Numerous other aspects are provided.

摘要： 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.

摘要： Certain aspects of the present disclosure provide techniques for reducing overhead for channel state information (CSI). Certain aspects provide a method for wireless communication. The method generally includes receiving a channel state information reference signal (CSI-RS), determining one or more feedback components associated with a CSI feedback type based on the CSI-RS, identifying that a payload of the one or more feedback components is to be compressed, compressing the payload, and reporting the compressed payload.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to use one or more channel state information (CSI) omission configurations for omitting portions of a CSI report. For example, a UE may receive a trigger to report CSI, and the UE may identify that a payload of the CSI report exceeds a capacity of resources for transmitting the report. As such, the UE may determine to use one or more CSI omission configurations, where each CSI omission configuration may correspond to dropping different portions of the CSI report. The selection of the CSI omission configuration to use may be based on a set of parameters associated with CSI reporting. In some cases, the UE selects the CSI omission configuration based on an explicit indication from the base station. Additionally or alternatively, the UE may implicitly determine the CSI omission configuration based on the parameters.
