Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a transmission of a channel status information (CSI) report based at least in part on receiving a CSI request via PDCCH repetitions, based at least in part on transmitting the CSI report via PUCCH repetitions, or based at least in part on transmitting the CSI report via PUSCH repetitions. The UE may determine, based at least in part on the determined transmission of the CSI report, CSI processing criteria including one or more of a CSI processing timeline, a CSI processing unit occupation duration, a resource and port occupation duration, or a CSI reference resource slot. The UE may selectively transmit the CSI report based at least in part on the determined CSI processing criteria. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques at a user equipment (UE) provide for indicating multiple beams to a base station for communications with the base station after detecting a beam failure. Using these techniques, the UE may rely on multi-beam operation to recover communications with the base station. The UE may transmit a random-access preamble indicating a first beam for communications with the base station, and the UE may transmit a control element in a data channel indicating a second beam for communications with the base station. In some cases, the messages used to carry the indications of the multiple beams may be based on a type of random-access procedure used to recover communications (e.g., a contention-based random-access (CBRA) procedure, a contention-free random-access (CFRA) procedure, or a two-step random-access procedure).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) associated with a DCI format for shared channel scheduling on a set of cells, wherein the DCI is associated with a cell radio network temporary identifier (C-RNTI) and a configured scheduling radio network temporary identifier (CS-RNTI). The UE may decode the DCI to identify a scheduling on the set of cells or to identify downlink feedback information (DFI) based at least in part on a determination of whether the C-RNTI or the CS-RNTI satisfies a cyclic redundancy check (CRC). Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a group-common physical downlink shared channel (PDSCH), where the group-common PDSCH is repeated for a number of repetitions. Accordingly, the UE may determine this number of repetitions and then monitor for the group-common PDSCH based on the number of repetitions. In some implementations, the group-common PDSCH may include a semi-static repetition scheme, where the number of repetitions is indicated via a group aggregation factor. Additionally or alternatively, the group-common PDSCH may include a dynamic repetition scheme, where the number of repetitions is indicated via a group repetition number. Additionally, the techniques described herein may enable the configuration for the repeated group-common PDSCH to include gaps between each repetition of the group-common PDSCH and for the UE to transmit acknowledgment feedback for the repetitions of the group-common PDSCH.

In some aspects, the method may be performed by a processor of the base station. Various aspects include determining a multicast bandwidth part (BWP) within a carrier bandwidth, sending an indication of the multicast BWP to one or more user equipment (UE) computing devices in communication with the base station, and scheduling transmission of multicast data in the multicast BWP.
