Abstract: Various aspects relate generally to sounding reference signal (SRS) reference indicators (SRIs) indicating an SRS associated with a transmission configuration to use for transmission of a data channel communication. Some aspects more specifically relate to an SRI indicating an SRS from an SRS resource having a same duplexing type as a slot in which the data channel communication is scheduled. In some aspects, the SRI may indicate an SRS from an SRS resource that is not a most-recent SRS resource based on the most-recent SRS resource having a different duplexing type than the slot in which the data channel communication is scheduled.

Abstract: Methods, systems, and devices for wireless communications are described. One or more user equipment (UEs) and network entities may communicate signaling using an SRS hopping scheme based on a numerical quantity of orthogonal frequency division multiplexing (OFDM) symbols in each set of OFDM symbols in a sounding reference signal (SRS) resource. Additionally, or alternatively, the UEs and the network entities may communicate signaling using a power normalization factor that depends on the numerical quantity of OFDM symbols and a numerical quantity of antenna ports for the SRS. In some examples, a network entity may indicate the numerical quantity of antenna ports, the numerical quantity of OFDM symbols in each OFDM symbol set, or both to a UE in control signaling. The UE may transmit the SRS to the network entity using the SRS resource and in accordance with the SRS hopping scheme, the power normalization factor, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first transmit receive point (TRP) may receive an indication of a detection of a scheduling collision of a first scheduled communication of a first scheduling message from the first TRP and a second scheduled communication of a second scheduling message from a second TRP. The first TRP may back off from transmitting the first scheduled communication based at least in part on the indication. Numerous other aspects are described.

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.
