Abstract: Methods, systems, and devices for sounding reference signal (SRS) resource indicator (SRI) association for configured grant (CG) based transmission and reception point (TRP) physical uplink shared channel (PUSCH) transmission are described. In some examples, a user equipment (UE) may receive first control signaling indicating a first and second sounding reference signal (SRS) resource set associated with a first and second set of power control parameter, respectively. The UE may receive second control signaling indicating a CG configuration, the first and second power control parameters for transmissions in the CG configuration. In some examples, the UE may determine a configuration status for one or more fields the first control signaling, the second control signaling, or both. The UE may select an SRS resource set based on the configuration status and may transmit one or more CG uplink transmissions with the CG configuration using the selected SRS resource set.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may communicate with a set of transceiver nodes (e.g., transmission reception points (TRPs)) in a first transceiver node operation mode (e.g., a multi-TRP mode). A first transceiver node of the set of transceiver nodes may receive, from a second of the set of transceiver nodes, an indication to switch between rate matching states. The first transceiver node may switch from a first rate matching state to a second rate matching state and may transmit a downlink shared channel based on a resource configuration associated with the second rate matching state. The UE may receive the shared channel based on an antenna port configuration determined by the UE based on the first transceiver node operation and rate matching information. The rate matching information may be provided by the first transceiver node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first transmit-receive point (TRP), a first synchronization signal block (SSB), of a first set of SSBs configured in a component carrier corresponding to a multi-downlink control information (DCI)-based multi-TRP (mTRP) configuration, that is associated with a first physical random access channel (PRACH) occasion. The UE may receive, from a second TRP, a second SSB, of a second set of SSBs configured in the component carrier, that is mapped to a second PRACH occasion. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a spatial division multiplexing configuration associated with a physical uplink shared channel (PUSCH) having a first set of transmission layers corresponding to a first sounding reference signal (SRS) resource set and a second set of transmission layers corresponding to a second SRS resource set. The UE may transmit a PUSCH communication that includes the first and second sets of transmission layers based at least in part on a port mapping that indicates a first association between a first subset of demodulation reference signal (DMRS) ports of a set of DMRS ports and the first set of transmission layers, and a second association between a second subset of DMRS ports and the second set of transmission layers. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A segment based feedback codebook may lead to more efficient and responsive codebook generation for hybrid automatic-repeat/request (HARQ) acknowledgment reporting. A segment-based feedback codebook may support codebook generation where each bit in an acknowledgment/negative-acknowledgment (ACK/NACK) codebook may correspond to a segment of resources. A network entity may schedule a user equipment with one or more messages within one or more segments. The UE may generate one ACK/NACK bit for each segment, and a HARQ codebook transmitted in a physical uplink control channel reporting occasion may include the ACK/NACK bits corresponding to the messages in those segments. A segment may be a set of time domain resources.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a downlink control information (DCI) message indicating a time slot for the UE to transmit feedback according to a codebook size. The UE may monitor a quantity of physical downlink control channel monitoring occasions (PMOs) within a subset of time slots before the time slot. The PMOs may include a first set of one or more PMOs associated with a first codebook generation characteristic and a second set of one or more PMOs associated with a second codebook generation characteristic. The UE may transmit the feedback via the time slot according to a first codebook size based on the monitoring. The first codebook size may be based on a quantity of PMOs included in the first set of PMOs associated with the first codebook generation characteristic.

Abstract: Certain aspects of the present disclosure provide a technique for wireless communications by a user equipment (UE). The UE receives signaling indicating a time gap to be applied between at least two physical uplink shared channels (PUSCHs) scheduled, via a single downlink control information (DCI), for transmission to different transmission reception points (TRPs). The UE transmits the at least two PUSCHs to the TRPs, in accordance with the time gap.
