Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to indicate to a base station a distribution of transmit antennas and receive antennas across a set of antenna panels, and the base station may configure resource sets for reference signal transmissions from the antenna panels based on the indicated distribution. In a first example, the UE may be configured to indicate a respective number of transmit antennas and receive antennas at each antenna panel. In a second example, the UE may be configured to indicate a sum of transmit antennas and a sum of receive antennas across all antenna panels, along with information on how the transmit antennas and receive antennas are distributed. Based on the indication, the base station may configure resource sets for reference signal transmission on sets of ports in resources of the resource sets.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for flexible cyclic redundancy check (CRC) lengths for downlink control information (DCI) message. For example, a network entity may determine a length of a CRC applied to a DCI message based on an attribute of the DCI message. In some examples, relationships between attributes of the DCI message and CRC lengths may be stored or configured at a user equipment (UE) or may be indicated to the UE via additional control signaling from the network entity. In some examples, the UE may transmit, to the network entity, a capability of the UE to support flexible CRC lengths for DCI messages. Varying the length of the CRC applied to the DCI message based on one or more attributes of the DCI message may enable the network entity to effectively balance overhead, payload size, and frequency of false alarms.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may derive a first potential length for a phase tracking reference signal demodulation reference signal (PTRS-DMRS) association bitfield based at least in part on a simultaneous transmissions with multiple panels (STxMP) configuration. The network node may derive a second potential length for the PTRS-DMRS association bitfield based at least in part on a single transmit receive point (sTRP) configuration. The network node may select a finalized length based at least in part on the first potential length and the second potential length. The network node may indicate a relationship between a PTRS port and a DMRS port based at least in part on transmitting downlink control information (DCI) using a DCI configuration that is associated with the finalized length of the PTRS-DMRS association bitfield. 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, from a first transmit receive point (TRP) of a multi-TRP with a full-duplex mode, spatial relationship information associated with a sub-band full-duplex (SBFD) mode. The UE may transmit, to the first TRP or a second TRP of the multi-TRP, one or more communications using the spatial relationship information associated with the SBFD mode. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Abase station may transmit downlink control information (DCI) to a user equipment (UE) that schedules repetitions of one or more physical uplink shared channels (PUSCHs) over repetitions of one or more transport blocks. In response to the DCI, the UE may multiplex first aperiodic-channel state information (A-CSI) on one or more repetitions of the one or more transport blocks in accordance with a repetition type of the PUSCH repetitions and one or more rules associated with the transport block repetitions. The UE may transmit the transport blocks including the one or more repetitions that include the multiplexed A-CSI to the base station. In some examples, the UE may select the one or more rules based on whether a timing offset between reception of the DCI and the transmission of the transport blocks is satisfied.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a medium access control (MAC) control element (CE) that indicates an update to a spatial relation configuration of the UE for physical uplink control channel (PUCCH) transmissions. The update may apply to a first PUCCH resource and may apply to other PUCCH resources in a group of PUCCH resources to which the first PUCCH resource belongs based at least in part on a bit included in the update or an indication of which PUCCH resources are to be in the group of PUCCH resources. The UE may update the spatial relation configuration of the UE for the first PUCCH resource or for all PUCCH resources in the group of PUCCH resources. The UE may transmit a PUCCH communication on at least the first PUCCH resource. Numerous other aspects are described.
