Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a first subset of channel measurement resources (CMRs) from a first CMR group for single transmission reception point (TRP) channel measurements associated with a first TRP, a second subset of CMRs from a second CMR group for single TRP channel measurements associated with a second TRP, and one or more CMR pairs including CMRs from the first subset and second subset. The UE may monitor the first subset, the second subset, and the one or more CMR pairs to generate a set of measurements for channel state information (CSI). The UE may then transmit a CSI report based on the set of measurements and including a number of bits to indicate one or more channel resource indicators (CRIs), where the number of bits is based on a number of the CMR pairs.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a control message that indicates a set of demodulation reference signal (DMRS) ports for DMRS communication between the UE and a network entity. The UE may select a subset of DMRS ports from the set of DMRS ports for DMRS bundling across a set of transmission occasions. The subset of DMRS ports may have fewer DMRS ports than the set of DMRS ports. The UE may communicate a set of DMRSs with the network entity over the set of transmission occasions using the set of DMRS ports. A portion of the set of DMRSs may correspond to the subset of DMRS ports, may satisfy a power condition for DMRS bunding, and may satisfy a phase continuity condition for DMRS bundling.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of first and second channel measurement resources (CMR) for measuring channel state information (CSI), each CMR associated with first and second transmission configuration indicator states (TCI). The UE may determine CSI for a joint transmission hypothesis which includes two rank indicators, two layer indicators, and two precoding matrix indicators, and may determine a priority for including each indicator in the CSI. In some cases, a UE may identify more than one CSI to transmit, and may determine an ordering of the one or more CSIs based on the CMR, and whether each of the one or more CSIs is associated with a single transmission hypothesis of the joint transmission hypothesis. Based on the various ordering rules of the CSI, the UE may generate and transmit CSI reporting.

Abstract: Methods, apparatuses, and computer readable medium for beam switch are provided. An example method may include transmitting, to a base station, a channel state information (CSI) report associated with a beam switch. The example method may further include performing the beam switch based on the CSI report and an absence, for a period of time after transmission of the CSI report, of a downlink control information (DCI) including a transmission configuration indicator (TCI) indication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine an association between multiple phase tracking reference signal (PTRS) ports and multiple codewords that are to be used for an uplink communication that uses multiple antenna port groups, and transmit the uplink communication using the multiple codewords based at least in part on the association. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured with one or more semi-persistent scheduling (SPS) configurations. A base station may transmit a first downlink control information (DCI) transmission to the UE that activates an SPS configuration, and the first DCI may indicate a non-numeric feedback timeline for reporting associated acknowledgment feedback. The base station may transmit a subsequent second DCI transmission that provides feedback resources, and the UE may receive the second DCI and identify timing and resources for SPS acknowledgment feedback based on the second DCI. The UE may then transmit the acknowledgment feedback for one or more SPS transmissions in the feedback resources that are indicated by the second DCI transmission.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for maintaining, between a user equipment (UE) and a component of a base station (BS), a mutual understanding of multiple sets of linked physical downlink control channel (PDCCH) candidates if some PDCCH candidates of the multiple sets of linked PDCCH candidates occupy a same set of resources. In one aspect, the UE may select to monitor one of the PDCCH candidates that occupy the same set of resources in accordance with a prioritization rule. Upon selecting one of the PDCCH candidates that occupy the same set of resources for monitoring by the UE, the UE and the component of the BS may select a reference PDCCH candidate for one or more of the multiple sets of PDCCH candidates in accordance with a reference selection rule.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE receives a configuration of multiple application time values for transmission configuration indication (TCI) state updates. The UE further receives downlink control information (DCI) in a control resource set (CORESET) associated with a first CORESET pool index associated with a first transmission reception point (TRP) and including a transmission configuration indication (TCI) state associated with a second CORESET pool index associated with a second TRP. The UE further transmits acknowledgement/negative acknowledgement (ACK/NACK) feedback to one or more TRPs based on a feedback mode configured for the UE, and applies the TCI state indicated in the DCI following the ACK/NACK feedback based on one of the multiple application time values and the feedback mode.

Abstract: Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) may receive control signaling scheduling transmission of aperiodic channel state information (A-CSI) via a set of uplink transmission repetitions, the set of uplink transmission repetitions including a first set of repetitions associated with a first sounding reference signal (SRS) resource set and a second set of repetitions associated with a second SRS resource set. The UE may receive additional control signaling scheduling transmission of an uplink control channel message that overlaps in time with at least one uplink transmission repetition of the set of uplink transmission repetitions. The UE may multiplex the uplink control channel message with at least one uplink transmission repetition of the set of uplink transmission repetitions, and may transmit the set of uplink transmission repetitions including multiple repetitions of the A-CSI and the multiplexed uplink control channel message.
