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: 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.

Abstract: Aspects described herein relate to transmitting a set of downlink reference signals corresponding to a set of uplink beams, receiving, from a user equipment (UE) and based on measuring at least one of the set of downlink reference signals, an indication to use a separate uplink beam that is different from a downlink beam for transmitting uplink communications, configuring, based on the indication, the UE with the downlink beam and the separate uplink beam, and receiving, from the UE, uplink communications based on the separate uplink beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink beam indication for at least one of a channel, a resource, a resource set, a bandwidth part, or a component carrier; and use the downlink beam indication for a group of channels, resources, resource sets, bandwidth parts, or component carriers. In some aspects, a UE may receive an indication of a spatial relation and multiple physical uplink control channel (PUCCH) resources to which the spatial relation is to be applied; and use the spatial relation to transmit on one or more PUCCH resources of the multiple PUCCH resources. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for sounding reference signal (SRS) resource configuration enhancements. A method generally receiving pre-configuration information for one or more reference signal transmissions, performing, at a first time during an ON duration of a discontinuous reception (DRX) cycle, measurements on one or more reference signals based, at least in part, on the pre-configuration information, determining if, at a second time during the ON duration after the first time, a trigger frame associated with the one or more reference signal transmissions has been received, and transmitting a measurement report corresponding to the measurements if a trigger frame has been received.

Abstract: A configuration to configure a UE to activate a subset of configured UL-TCI states. The apparatus receives a configuration of UL-TCI states and an activation of a subset of configured UL-TCI states. The apparatus receives DCI in a PDCCH scheduling an UL transmission with one or more TCI states of activated TCI states. The apparatus transmits the UL transmission based on the one or more TCI states.
