Abstract: Certain aspects of the present disclosure provide techniques for managing beam failure recovery operations. A method that may be performed by a user equipment (UE) generally includes selecting a priority associated with an uplink (UL) control channel for indicating a beam failure recovery request (BFRQ), detecting that the UL control channel is scheduled for transmission using first resources at least partially overlapped with second resources scheduled for transmission of another UL signal, determining, in response to the detection, whether to transmit the UL control channel based on the priority associated with the UL control channel, and transmitting or dropping the UL control channel in accordance with the determination.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for performing rate matching when resources for a physical downlink shared channel (PDSCH) overlap with resources of a control resource set (CORESET) in which a physical downlink control channel (PDCCH) that scheduled the PDSCH. As used herein, rate matching generally refers to the process of repeating or puncturing bits on a transport channel.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first transmit power that is to be used for a first transmission to a source cell and a second transmit power that is to be used for a second transmission to a target cell during a dual-active-protocol stack (DAPS) handover procedure. The UE may transmit, concurrently, the first transmission to the source cell using the first transmit power and the second transmission to the target cell using the second transmit power. Numerous other aspects are provided.

Abstract: Aspects relate to wireless communication on multiple component carriers. In some examples, a user equipment (UE) may apply pathloss reference signal information received via a medium access control-control element (MAC-CE) to a set of component carriers for transmitting uplink information. Examples of such transmissions of uplink information include a physical uplink shared channel transmission, a physical uplink control channel transmission, and a sounding reference signal transmission. In some examples, the UE may identify the set of component carriers based on a component carrier identified by the MAC-CE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of beams, for which a corresponding uplink beam indication is not configured, associated with a set of transmit-receive points (TRPs) based at least in part on at least one of a downlink control information (DCI) configuration, a transmission configuration indicator (TCI) codepoint mapping, a control resource set (CORESET) configuration, or a TRP index, wherein the set of beams includes a sounding reference signal (SRS) beam or a physical uplink control channel (PUCCH) beam. The UE may communicate with the set of TRPs using the set of beams based at least in part on determining the set of beams. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for managing beam failure recovery operations. A method that may be performed by a user equipment (UE) generally includes determining at least one reference signal (RS) associated with a first cell that is configured without a control-resource set (CORESET). The method also includes monitoring the at least one RS associated with the first cell. The method further includes detecting a beam failure on the first cell based on the monitoring of the at least one RS.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a user equipment (UE). The apparatus identifies an overlap between resources for transmitting a scheduling request (SR) and a transmission occasion for transmitting hybrid automatic repeat request (HARQ) feedback. The apparatus determines whether to transmit the SR or the HARQ feedback to a base station based on at least one of a type of the SR, a relationship between a first beam for an uplink control channel and a second beam for downlink communication, or a content of the HARQ feedback. Then, the apparatus transmits the SR or the HARQ feedback based the determination.
