1. A baseband processor for a user equipment (UE) configured to, when executing instructions stored in a memory, perform operations comprising:
determining by measuring, for each beam of one or more beams, an associated beam quality metric for that beam based on one or more of a Synchronization Signal Block (SSB) or a Channel State Information Reference Signal (CSI-RS) associated with that beam;
selecting a beam of the one or more beams based on the associated beam quality metric, wherein the selected beam is mapped to a selected set of Physical Uplink Control Channel (PUCCH) resources; and
generating, during a Discontinuous Reception (DRX) on duration of the UE, a Scheduling Request (SR) for transmission over the best selected beam using the selected set of PUCCH resources.
