Abstract: To schedule panel specific uplink transmissions, the UE may assist in the scheduling of the panel specific uplink transmission by improving the manner in which the specific panel is indicated for uplink transmission. The apparatus receives, from a base station, an indication of a UE panel for an uplink transmission. The apparatus determines a Tx panel at the UE based on the indication of the UE panel. The apparatus transmits, to the base station, the uplink transmission using the Tx beam associated with the Tx panel.

Abstract: Wireless communications systems and methods related to handling link failures in a first cell and a second cell are provided. A wireless communication device can detect a first link failure associated with a first cell and can detect a second link failure associated with a second cell. Additionally, the wireless communication device can perform a link failure recovery procedure. This may include prioritizing a first link failure recovery for the first cell over a second link failure recovery for the second cell. Other aspects and features are also claimed and described.

Abstract: A configuration for configuring and updating the spatial relationship of multiple physical uplink control channel (PUCCH) resources in a single message, thereby reducing signaling overhead. A user equipment (UE) constructs a message associated with at least one of a plurality of component carriers (CCs) or a plurality of bandwidth parts (BWPs) indicating a same spatial relation for the at least one of the plurality of CCs or the plurality of BWPs. The UE transmits the message to a base station. The base station transmits a message to the UE configuring multiple spatial parameters for the at least one of the plurality of CCs, the plurality of BWPs, or a plurality of uplink/downlink resources.

Abstract: A beam failure caused by an event initiated by the UE such as folding of the UE or shutting down of a UE antenna penal may be predictable. Accordingly, the UE may declare a beam failure detection (BFD) without going through a potentially long detection procedure. Disclosed herein are apparatus and methods for detecting beam failure and terminating BFD earlier than the current DFD process would have. The method may include identifying a beam failure (BF) event at the UE that impacts at least one beam pair link (BPL) and communicating a request to an associated base station to stop communicating on an impacted beam pair link, without going through an entire BFD process.

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.
