Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a path loss reference signal (PLRS) ready time that indicates an interval after which a PLRS is to be ready for use in performing an uplink power control operation, wherein the PLRS is activated by a downlink control information (DCI) based PLRS activation command; and perform the uplink power control operation, based at least in part on the PLRS, after the PLRS ready time. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for reducing path loss reference signal (PL RS) application time. An example method generally includes receiving signaling indicating activation of path loss (PL) reference signals (RSs), determining that the UE can reduce an application time for using the PL RS for uplink power control purposes, wherein the reduced application time is reduced relative to a non-reduced application time, and using PL RS measurements taken according to the reduced application time for uplink power control.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a user equipment. The UE receives an indication from a base station that a medium access control-control element (MAC-CE) activation of a pathloss reference signal is enabled. The UE receives a MAC-CE activating the pathloss reference signal. The UE determines the pathloss reference signal based on the MAC-CE and the indication that indicates that the MAC-CE activation of the pathloss reference signal is enabled. Then, the UE estimates a downlink pathloss based on the pathloss reference signal that is activated by the MAC-CE.

Abstract: Certain aspects of the present disclosure provide techniques for reporting and responding to beam failure events based on a receiving cell restriction rule. An example method includes detecting an occurrence of a threshold number of beam failures for a connection between a UE and a set of cells; identifying a candidate beam for restoring the connection between the UE and the set of cells in response to detecting the occurrence of the threshold number of beam failures; transmitting, to one or more cells in the set of cells, a beam failure recovery (BFR) request including an identification of the candidate beam; receiving, from a cell in the set of cells, a BFR response in response to transmitting the BFR request, wherein the BFR response is received according to a restriction rule; and resuming communications with the set of cells based on the BFR response.

Abstract: Aspects relate to mechanisms for wireless communication devices to report a beam failure. A UE detects a beam failure with a cell. The UE transmits a beam failure recovery request including an indication of a candidate beam to a base station in response to detecting the beam failure. The base station transmits a beam failure recovery response to the UE indicating whether the beam failure recovery request is received. The UE applies the candidate beam indicated in the beam failure recovery request for a downlink channel following a predetermined number of symbols after an end of the beam failure recovery response. The UE transmits an acknowledgment (ACK) message to the base station when the beam failure recovery response is decoded. The UE applies the candidate beam indicated in the beam failure recovery request for a downlink channel following a predetermined number of symbols after an end of the ACK message.

Abstract: A configuration to enable a UE to switch beams of respective CCs based on certain factors (e.g., RTD or TCI states), and not switch the beams simultaneously. The apparatus receives, from a base station, a transmission including an indication to change at least one of a TCI state for multiple CCs, a spatial relation for the multiple CCs, or a PL RS for the multiple CCs. The apparatus switches beams in response to the transmission, where timing of the switching is based on a grouping of the multiple CCs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may combine an indication of a beam failure recovery request or one or more scheduling requests with uplink control information that is to be transmitted in a resource. The UE may transmit the uplink control information combined with the indication in the resource. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit a message, to a user equipment (UE), instructing the UE to activate or update a reference signal (RS) corresponding to an uplink communication transmitted by the UE. The base station may communicate with the UE, after a time period, using a beam configuration of the base station that corresponds to a beam configuration of the UE for transmitting the RS, the time period being based at least in part on a determination of whether the UE identified the beam configuration of the base station. Numerous other aspects are provided.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. A component carrier group may be configured for beam management, such that beam management on a first component carrier is applied to one or more second component carriers to reduce signaling overhead associated with controlling a defined group of component carriers. A user equipment may be configured to identify a group of component carriers and, when a beam failure detection reference signal is received from a base station on a first component carrier, identify a beam failure condition for the first component carrier and one or more second component carriers of the group of component carriers.

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.
