Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a configuration that indicates a time alignment timer associated with a timing advance group (TAG) for a bandwidth part (BWP) or a component carrier (CC) configured for multiple downlink control information (multi-DCI) based multiple transmission reception point (multi-TRP) communications. The UE may start the time alignment timer for a TRP. The UE may flush one or more hybrid automatic repeat request (HARQ) identifiers (IDs) from a HARQ buffer associated with the TRP based at least in part on an expiration of the time alignment timer. 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 transmit, to a network entity, a scheduling request that indicates full antenna panel availability or partial antenna panel availability. The UE may receive, from the network entity, an uplink grant that schedules an uplink communication in connection with the scheduling request, wherein the uplink grant is based at least in part on the full antenna panel availability or the partial antenna panel availability indicated by the scheduling request. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may establish communication with a set of transmission reception points including a first transmission reception point and a second transmission reception point. The UE may receive a single control message including one or more respective timing advance indications for uplink channel transmissions to one or more respective transmission reception points. In some examples, each timing advance indication may identify a respective transmission reception point using a respective timing advance value. The UE may determine a first timing advance value for the uplink channel transmissions based on the one or more respective timing advance indications identifying a respective transmission reception point. The UE may then transmit, to the first transmission reception point, an uplink channel transmission over an uplink channel using the first timing advance value determined for the first transmission reception point.

Abstract: Methods, systems, and devices for wireless communications are described. Methods, systems, and devices for wireless communications are described. The described techniques provide for joint hybrid automatic repeat request (HARQ) feedback for sidelink transmissions and downlink transmissions. In some examples, a base station may transmit control signaling to a user equipment (UE) indicating a configuration for a joint HARQ codebook. The UE may receive a set of sidelink transmissions and a set of downlink transmissions, generate a joint HARQ codebook based on a downlink counter (e.g., a counter downlink assignment index) for the downlink transmissions and a sidelink counter (e.g., a counter sidelink assignment index) for the sidelink transmissions, where the downlink counter and the sidelink counter are jointly summed, and transmit feedback message to the base station for the downlink transmissions and the sidelink transmissions based on the joint HARQ codebook.

Abstract: Method and apparatus for PHR for multi-PUSCH repetitions. The apparatus selects a first PUSCH to carry a first MAC-CE having a first PHR. The apparatus determines a first value of the first PHR based on a third PUSCH. The apparatus selects a second PUSCH to carry a second MAC-CE having a second PHR based on the third PUSCH or the first PUSCH. The apparatus determines a second value of the second PHR based on a fourth PUSCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may set, for frequency hopping of multiple physical uplink shared channel (PUSCH) repetitions of multiple transport blocks (TBs), a first frequency for a first frequency hop and a second frequency for a second frequency hop. The UE may transmit the PUSCH repetitions with frequency hopping such that the PUSCH repetitions alternate between the first frequency hop and the second frequency hop. Numerous other aspects are described.
