Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit beam information, associated with the UE, during a random access channel (RACH) procedure and while in an inactive mode or in an idle mode. The UE may remain in the inactive mode or in the idle mode after transmitting the beam information. Numerous other aspects are provided.

Abstract: A user equipment (UE) determines a beam failure of a default uplink beam for the UE. The UE transmits an uplink beam failure report in response to determining the beam failure of the default uplink beam, the uplink beam failure report indicating that a reported beam is the default uplink beam for the UE. A base station receives an uplink beam failure report from the UE and determines that a reported beam is a default uplink beam for the UE.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication including random access between a base station and a user equipment (UE). The UE transmits at least two first random access messages (Msg 1) to multiple transmission reception points (TRPs) of at least one cell using different resources for the multiple TRPs. The UE monitors for at least two second random access messages (Msg 2) from the multiple TRPs of the at least one cell using different resources for the multiple TRPs.

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: 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: 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.

Abstract: In an embodiment, a base station determines a spatial relationship for a group of PUCCH resources, and transmits a control message that indicates the spatial relationship to a UE. The UE receives the control message and stores an indication of the spatial relationship. In some designs, the control message conveying the spatial relationship identifies the group of PUCCH resources via the PUCCH group index, while in other designs a different identification mechanism may be used. In another embodiment, a base station determines an association between a group of PUCCH resources and a PUCCH group index, and transmits a control message that indicates the association to a UE. The UE receives the control message and stores an indication of the association.

Abstract: An apparatus for wireless communication based on sidelink accumulates a value, e.g., a token value, based on an accumulation rate of a transmit beam. When the apparatus has a packet for transmission over sidelink, the apparatus determines whether to transmit the packet over the sidelink based on a current accumulation of the value. The accumulation may be based on any of a CBR, a CR, and/or a feedback rate. A base station may measure interference on an access link of the base station and transmit a side link parameter that controls accumulation of a value at a transmitting device for the transmission of sidelink communication based on the measured interference.

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.
