    Abstract: Embodiments include methods that may be performed by a processor of a mobile device and a processor of a base station for managing beam failure recovery (BFR). The processor of the mobile device may determine whether a beam failure of a communication link with a base station has occurred, determine whether contention free random access (CFRA) resources have been configured in response to determining that a beam failure has occurred, and initiate contention based random access (CBRA) in response to determining that CFRA resources have not been configured. The processor of the base station may receive from the mobile device a message initiating CBRA, determine whether a downlink beam or quasi-colocation (QCL) assumption a downlink resource of a physical random access channel (PRACH) is different from any active downlink beam or QCL assumption, and perform CBRA with the mobile device.

    Abstract: Apparatus, methods, and computer program products for PHY priority for wireless communications are provided. An example apparatus may multiplex a first uplink control information transmission based on a first uplink resource and a second uplink control information transmission based on a second uplink resource that overlaps in time with the first uplink resource, at least one of the first uplink resource and the second uplink resource being for full-duplex communication. The example apparatus may determine, based on applying a multiplexing rule on the full-duplex communication, whether to use the first uplink resource associated with a first beam or the second uplink resource associated with a second beam. The example apparatus may transmit a multiplexed uplink control information transmission using a determined uplink resource based on the multiplexing rule.

    Abstract: In a first aspect, a method of wireless communication includes receiving, by a user equipment (UE) from a first network entity, a multiple component carrier (CC) signaling message including multiple CC scheduling information. The method also includes receiving, by the UE from, a downlink control information transmission indicating a downlink control information indication for multiple CCs, and determining a first downlink control information parameter for a first CC and a second downlink control information parameter for a second CC based on the downlink control information indication and the multiple CC scheduling information. The method further includes receiving, from the first network entity, a first downlink transmission for the first CC based on the first downlink control information parameter, and receiving, from a second network entity, a second downlink transmission for the second CC based on the second downlink control information parameter. In other aspects, uplink transmissions may be sent.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a single downlink control information (DCI) message that schedules communications on multiple cells, wherein the single DCI message indicates multiple time domain resource assignments (TDRAs) corresponding to the multiple cells, wherein each of the multiple TDRAs corresponds to a different scheduled communication; and communicate using the multiple TDRAs corresponding to the multiple cells, wherein the communicating comprises: transmitting the communications using the multiple TDRAs corresponding to the multiple cells, or receiving the communications using the multiple TDRAs corresponding to the multiple cells. Numerous other aspects are provided.

    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive one or more messages scheduling a first uplink transmission over a first physical uplink control channel (PUCCH) resource on a first component carrier and a second uplink transmission over a second PUCCH resource on a second component carrier and, if the first PUCCH resource and the second PUCCH resource overlap in time, the UE 115 may transmit the first uplink transmission and the second uplink transmission using spatial relation information in accordance with a spatial relation configuration that is dedicated for selecting spatial relation information for simultaneous PUCCH transmissions on different component carriers. A network entity may configure the UE with spatial relation information for the overlapping PUCCH resources and the UE may select spatial relation information to use for the simultaneous uplink transmissions in accordance with the spatial relation configuration.

    Abstract: Methods, systems, and devices for wireless communications are described. A base station may switch semi-persistently scheduled (SPS) or configured grant (CG) transmissions for a user equipment (UE) across component carriers according to a resource switching pattern to avoid resource conflict with control information on one or more component carriers. The resource switching pattern may have multiple flows spanning different component over a time interval for redundancy. According to some aspects, a base station may transmit a synchronization signal block (SSB) in one of a set of flexible SSB locations or candidate SSB locations, where each of the set of candidate SSB locations is associated with a respective SSB identifier.
