Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a random access channel (RACH) procedure using a first beam associated with a base station (BS). The UE may transmit, to the BS and during the RACH procedure, an uplink control information (UCI) communication that indexes into a resource set of beams to indicate one or more second beams associated with the BS. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that processing or transmission associated with a scheduling request is preempted, and perform one or more scheduling request preemption actions, associated with the scheduling request, based at least in part on determining that the processing or transmission is preempted. Numerous other aspects are provided.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a dual connectivity configuration for a set of communication links, where at least one communication link of the set includes a sidelink. The UE may transmit a report based on an event associated with the sidelink that triggers the power headroom report. Additionally or alternatively, the UE may identify a carrier aggregation configuration for a set of communication links where at least one communication link of the set is a sidelink. The UE may determine an event associated with the sidelink that triggers a power headroom report, and transmit the power headroom report based on the determined event associated with the sidelink that triggers the power headroom report.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may autonomously initiate a handover procedure and select a target base station for the handover procedure. The UE may measure a signal from the source base station or the target base station, or both, and the UE may determine whether specific criteria at both base stations are within a pre-configured range. If the criteria at both base stations are within the pre-configured range, the UE may identify the target base station as a potential candidate for a handover. Accordingly, when the UE determines that radio conditions with the source base station are deteriorating (or fall below a threshold), the UE may initiate a handover to the target base station autonomously and without specific direction from the source base station.

Abstract: In an access network, a base station may aggregate data packets for a user equipment (UE) into transport blocks and configure a control channel to allow the UE to sleep between control channel monitoring occasions to save power. Such data aggregation, however, may be subject to changes in traffic load and/or link quality that may result in a too low data rate or too frequent monitoring. A base station that receives data to transmit to the UE and aggregates the data according to configured control configuration parameters of the UE may determine that a link quality or a traffic load for the UE has changed. The base station may reconfigure the control channel configuration parameters of the UE based on at least one of the link quality or the traffic load in order to obtain a data rate that satisfy the traffic load for the UE.

Abstract: New radio (NR) power headroom report (PHR) design for millimeter wave (mmWave) deployment is discussed. The power control process for mmWave may include beam-specific periodic PHR reporting and user equipment (UE)-specific event-trigger PHR reporting. The periodic PHR reporting may either provide a single PHR that includes power headroom information for each of the serving beams, or the UE may be configured to measure and report PHR for different beams in different slots. When reporting a single PHR with power headroom information for multiple serving beams, a beam index may be included in the reserved bits of the PHR. For the event-trigger PHR, the PHR reported based on a detected event trigger may provide power headroom information only for the current serving beam, or for all serving beams.
