    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit to a base station (BS), information indicating a medium access control (MAC) security capability of the UE. The UE may receive from the BS, a communication that includes an indication of a MAC security configuration for communications between the UE and the BS. The indication of the MAC security configuration may be based at least in part on the MAC security capability of the UE. Numerous other aspects are provided.

    Abstract: Generally, the described techniques provide for a user equipment (UE) generating a scheduling request (SR) for a set of data for an uplink transmission from the UE to a base station. The UE may determine whether the SR for the set of data is associated with a grant-free configuration for the UE. The grant-free configuration may indicate a set of time-frequency resources that the UE may use to transmit the set of data. The UE may transmit to the base station an indication of whether the SR is associated with the grant-free configuration. If the SR is associated with a grant-free configuration for the UE, the UE may use the corresponding resources to transmit the set of data to the base station, and the base station may then decode the data based on having received the indication of the resources by way of the grant-free configuration.

    Abstract: A user equipment (UE) may provide feedback regarding beam pairs used for wake-up signal (WUS) transmissions via uplink resources configured for WUS-based beam management feedback. A correspondence between WUSs and uplink resources for feedback may be semi-statically configured via radio resource control (RRC) signaling, may be dynamically indicated by each WUS, etc. In some examples, uplink resources for different UEs may be distinctive (e.g., UE-specific). In some cases, each beam used to transmit the wake-up message (e.g., each WUS) may have separate uplink resources, or all beams may share the same uplink resource (e.g., or some combination of uplink resources). As such, the UE and base station may identify one or more beams of sufficient quality (e.g., for control channel transmissions during a discontinuous reception (DRX) on-duration) based on the feedback (e.g., beam report) conveyed by the UE via the configured uplink resources for WUS-based fast beam management techniques.

    Abstract: Techniques to enable and provide beam failure recovery (BFR) operation for discontinuous reception (DRX) modes with wakeup signal (WUS) monitoring are described. DRX mode operation may be altered based on a BFR procedure implemented by a user equipment (UE). DRX mode operation may be altered for allowing a UE to start a DRX active time after transmitting a BFR request signal of a BFR procedure. Additionally or alternatively, DRX mode operation may be altered for allowing a UE to start an ON duration timer for a next DRX cycle after transmitting a BFR request signal of a BFR procedure. In another example, DRX mode operation may be altered for allowing a UE to monitor a BFR search space set regardless of DRX status, after transmitting a BFR request signal for a BFR procedure. Other aspects and features are also claimed and described.
