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.
