    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that multiple physical uplink channels scheduled for the UE overlap. The multiple physical uplink channels may include a first physical uplink channel and a second physical uplink channel that are associated with different priority levels. The UE may transmit at least one of the first physical uplink channel or the second physical uplink channel according to a prioritization or a multiplexing of the first physical uplink channel and the second physical uplink channel. The prioritization or the multiplexing is based at least in part on whether the UE is enabled to perform simultaneous physical uplink control channel and physical uplink shared channel transmissions. Numerous other aspects are provided.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration message indicating a configured grant-small data transfer (CG-SDT) group that includes the UE. The CG-SDT group is associated with a downlink beam of the base station and one or more CG-SDT occasions. The UE may transmit, to the base station and within the one or more CG-SDT occasions, an uplink communication, using an uplink beam of the UE corresponding to a downlink beam of the UE, where the downlink beam of the UE is associated with the downlink beam of the base station used for transmitting at least one of the configuration message, a paging message, or a reference signal. Numerous other aspects are provided.

    Abstract: Aspects of the present disclose provide various methods and apparatuses for communicating, controlling, and configuring component carrier and bandwidth part (BWP). A scheduling entity receives a capability report from a user equipment (UE). The capability report indicates a capability of the UE to utilize at least one of carrier aggregation (CA) or one or more bandwidth parts. The scheduling entity transmits a command to the UE to reconfigure at least one of a CA configuration or a bandwidth part (BWP) configuration. The scheduling entity determines an anticipated response timing of an acknowledgment (ACK) of the command based on the capability report received from the UE. The scheduling entity receives the ACK according to the anticipated response timing.

    Abstract: Aspects of the disclosure relate to a base station providing a user equipment (UE) with a sticky uplink beam assignment for one or more uplink signals. The UE may use the sticky uplink beam assignment for transmission of uplink signals until a new sticky uplink beam assignment is received. In some examples, the sticky uplink beam assignment may include an uplink beam identifier (ID) identifying an uplink beam associated with the transmission of an uplink signal. The uplink beam identified by the uplink beam ID may be used by the UE for transmission of the uplink signal and either all subsequent uplink signals (e.g., physical uplink control channel (PUCCH) and/or physical uplink shared channel (PUSCH)) or subsequent uplink signals of particular uplink channel types (e.g., dynamic PUSCH, configured grant (CG), PUCCH, etc.) until a new uplink beam ID is received. Other aspects, features, and examples are also claimed and described.

    Abstract: Wireless communication devices are adapted to facilitate a random access procedure. According to one example, scheduled entity can transmit a first transmission that is received by a scheduling entity. The first transmission may include a physical random access channel (PRACH) preamble sequence and a first message including information for determining a device-specific network identifier for the scheduled entity. The scheduling entity may transmit a second transmission that is received by the scheduled entity. The second transmission may include information on a physical downlink control channel (PDCCH) addressed to the device-specific network identifier for the scheduled entity, and a second message on a physical downlink shared channel (PDSCH). Other aspects, embodiments, and features are also included.
