Abstract: Channel state information-reference signal (CSI-RS) resources are disclosed with multiple transmission configuration indication (TCI) states. Example aspects of the present disclosure provide for indications that a given CSI-RS resource is associated with multiple TCI states within various configuration control signaling, depending on whether the CSI-RS is periodic, semi-persistent, or aperiodic. Additionally, where any trigger state corresponds to a CSI-RS resource set in which one or more CSI-RS resources are associated with multiple TCI states, one or more quasi-co-location (QCL) assumptions of the downlink transmission may also be applied by a user equipment (UE) to reception of the CSI-RS resources, where the scheduling offset is less than the threshold beam switch timing reported by the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a channel state information (CSI) report configuration that includes configuration information associated with multiple CSI reports. The UE may generate a CSI report message in which the multiple CSI reports are separately encoded and ordered based at least in part on one or more rules. In some aspects, the CSI report message may be generated for transmission on one or more of a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH). Numerous other aspects are provided.

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: Certain aspects of the present disclosure provide techniques for channel state information (CSI) processing occupation determination that can be used even in multiple transmission reception point (mTRP) scenarios. A method that may be performed by a user equipment (UE) includes receiving a channel state information (CSI) reporting configuration configuring the UE with a plurality of CSI reference signal (CSI-RS) resources for channel measurement (CMRs). The method includes determining a number of occupied CSI processing units, a number of occupied active CSI resources, and/or a number of occupied active CSI-RS ports based on an actual number of CSI measurements. The method includes performing CSI measurement based on the determination.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a plurality of resource sets, wherein a resource set, of the plurality of resource sets, includes one or more type-0 resources and one or more type-1 resources, wherein the one or more type-0 resources are configured with a single transmission configuration indicator (TCI) state and the one or more type-1 resources are configured with at least two TCI states; identify a plurality of hypotheses; identify a set of hypothesis groups, wherein the plurality of hypotheses are divided into the set of hypothesis groups; and report, to one or more transmit receive points (TRPs) and for the set of hypothesis groups, a set of channel state information (CSIs) corresponding to the set of hypothesis groups. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently reporting channel state information (CSI) with limited overhead. In one aspect, if a user equipment (UE) is configured to transmit data and CSI to a base station periodically, the UE may transmit the CSI when the UE has data to transmit to the base station. In particular, the UE may transmit data and a CSI report during a transmission opportunity if the UE has data to transmit in the transmission opportunity. Otherwise, the UE may suppress transmission of the CSI report. In another aspect, a UE may be configured to transmit CSI to abase station when downlink channel conditions change. In particular, the UE may request to report CSI to the base station when channel conditions change, and the base station may trigger the UE to report the CSI after receiving the request.

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.
