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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a collision between a beam failure recovery request (BFRQ) transmission to trigger a beam failure recovery for a secondary cell and another uplink transmission on an uplink channel; and transmit, on the uplink channel, at least one of the BFRQ transmission or the other uplink transmission based at least in part on multiplexing rule. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems one or more first user equipment (UE) may be configured to relay transmissions to second user equipment upon reception of a negative acknowledgment (NACK) from the second user equipment. In other systems, one or more UEs may be configured to receive transmissions relayed from other UEs in response to a NACK.

Abstract: Aspects described herein relate to bi-direction preemption indication transmissions. In one example, a node such as an integrated access and backhaul (IAB) node may determine that a set of one or more resources are preempted for use for both an uplink transmission and a downlink transmission, and transmit, to a user equipment (UE), the bi-direction preemption indication indicating that the set of one or more resources are preempted for use for both of the uplink transmission and the downlink transmission. In another example, a UE may receive a bi-direction preemption indication indicating that a set of one or more resources are preempted for use for both an uplink transmission and a downlink transmission, and perform rate matching for both of the uplink transmission and downlink transmission based on the set of one or more resources indicated by the bi-direction preemption indication.

Abstract: Aspects provide a mechanism for activating a secondary serving cell (SCell) in a wireless communication network supporting a multi-cell transmission environment. In some examples, a scheduled entity (e.g., a UE) in a connected mode with a primary serving cell (PCell) may synchronize with the SCell to activate the SCell for multi-cell communication with the PCell and the SCell. To enable synchronization with the SCell, the PCell may trigger communication and processing of one or more reference signals between the scheduled entity and the SCell.
