    Abstract: Methods, systems, and devices for enhanced aperiodic sounding reference signal (A-SRS) scheduling are described. In some examples, a user equipment (UE) may transmit, to a base station, a capability message that indicates a capability of the UE to support dynamic scheduling of resources for an SRS. In some examples, the UE may receive, from the base station in response to the capability message, a downlink control message indicating a time domain allocation for the SRS and a frequency domain allocation for the SRS. In some examples, the UE may transmit the SRS using a set of resources in response to the downlink control message, the set of resources selected based at least in part on the time domain allocation for the SRS and the frequency domain allocation for the SRS.

    Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive signaling indicating a configuration for the UE to communicate with a first transmission reception point (TRP) and a second TRP. The UE may receive a control signal identifying a set of channels sharing a common transmission configuration indication (TCI), where the common TCI may indicate a first TCI state for the first TRP and a second TCI state for the second TRP. The UE may communicate with at least one of the first TRP or the second TRP according to the common TCI based on receiving the control signal.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicating: a first configuration of multiple control resource set (CORESET) pool indexes for a first component carrier and for a second component carrier, and a second configuration of a first set of multiple timing advance groups (TAGs) for the first component carrier and a second set of one or more TAGS for the second component carrier, wherein the second set of one or more TAGs is configured based at least in part the first set of multiple TAGs. The UE may transmit one or more communications via the first component carrier and the second component carrier based at least in part the first set of multiple TAGs and the second set of one or more TAGS. 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 configuration information indicating a power offset, per resource block, between one or more first resource blocks to carry acknowledgement/negative acknowledgement feedback and one or more second resource blocks in a common interlace. The UE may transmit, using the power offset and using a transmission power that depends on whether a downlink pathloss value is indicated in the configuration information, a physical sidelink feedback channel transmission in the one or more first resource blocks and the one or more second resource blocks. Numerous other aspects are described.

    Abstract: Certain aspects of the present disclosure provide techniques for type-1 hybrid automatic repeat request (HARQ) codebook usage and hashing for multi-bit sidelink feedback. Certain aspects provide a method for wireless communication by a first user equipment (UE). The method generally includes receiving, from a second UE, one or more sidelink data messages over a first subchannel during a time period having a duration of a first number of slots that is greater than one and transmitting, to the second UE, over a plurality of resource blocks of a sidelink feedback channel resource of a first feedback channel occasion of a set of periodically occurring feedback channel occasions, a first feedback message associated with the one or more sidelink data messages, wherein the first feedback message indicates a plurality of feedback bits comprising one or more feedback bits associated with the one or more sidelink data messages.

    Abstract: PDCCH/PDSCH multiplexing with rank adaptation is described. An apparatus is configured to receive a PDSCH transmission multiplexed with a PDCCH transmission that includes information to schedule the PDSCH. The PDCCH has a first rank, the PDSCH has a second rank, and both share a DMRS(s). The apparatus is configured to decode the PDSCH using a channel estimation for the PDSCH and the second rank of the PDSCH that is based on the shared DMRS indication. Another apparatus is configured to encode a PDSCH transmission multiplexed with a PDCCH transmission that includes information to schedule the PDSCH. The PDCCH has a first rank, the PDSCH has a second rank, and both share a DMRS(s). The apparatus is configured to provide, for a UE, the PDSCH transmission multiplexed with the PDCCH transmission that schedules the PDSCH and a shared DMRS indication indicative of the shared DMRS(s).
