Abstract: Certain aspects of the present disclosure provide techniques for using multiple timing advances for simultaneous uplink reception, for example, using multiple antennas, beams, and/or antenna panels. A method that may be performed by a user equipment (UE) includes configuring a plurality of timing advances (TAs) for a plurality of uplink transmissions using a plurality of antennas. The UE transmits the plurality of uplink transmissions to a base station (BS) using the plurality of antennas based on the plurality of timing advances. A method that may be performed by a BS includes receiving a plurality of uplink transmissions from a UE and transmitting timing information to the UE in a message, the timing information based on when each of the plurality of uplink transmissions was received at the BS.

Abstract: Certain aspects of the present disclosure provide techniques for control channel resource grouping and spatial relation configuration. Aspects of the present disclosure provide a method of wireless communication by a user equipment (UE). The method generally includes receiving an indication of one or more groupings of one or more control channel resources within a configured bandwidth. Each grouping is associated with a spatial relation. The UE applies a spatial relation for a control channel transmission using one or more control channel resources in a grouping of the one or more groupings. The grouping is associated with the spatial relation.

Abstract: A UE detects a beam failure on a first CC. The UE determines whether to transmit a BFRQ to a base station on the first CC or a second CC. The UE determines whether to include a NBI report in the BFRQ. The UE transmits the BFRQ to the base station on the first CC or the second CC. The base station receives a BFRQ from a UE on a first CC or a second CC. The base station determines a new beam for the first CC, where the determination of the new beam is based on a RACH procedure when the BFRQ is received on the first CC or a NBI report in the BFRQ when the BFRQ is received on the second CC. The base station initiates a BFR procedure with the UE for the first CC based on the BFRQ and the new beam determination.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a beam failure associated with a component carrier (CC) of a plurality of CCs that are aggregated. The UE may identify, based at least in part on detecting the beam failure, a CC group in which the CC and one or more other CCs, of the plurality of CCs, are included. The UE may transmit, to the BS, a beam failure recovery request (BFRQ) communication associated with the CC group. Numerous other aspects are provided.

Abstract: The present disclosure provides signaling for multi-panel user equipment (MPUE) activation. The MPUE may have at least an active first panel and an inactive second panel. The MPUE may determine to activate the second panel. The MPUE may activate the second panel in response to the determination. The MPUE may transmit, from the active first panel to a base station, a status indicating that the second panel is active. The MPUE may transmit, after an activation time, an uplink transmission from the second panel to the base station.
