User equipment indication for adaptive scheduling restrictions

Improved techniques of managing measurement gaps for MPUEs include identifying an idle time for the UE in a coordinated and network-controlled manner during which the UE is able to perform SSB/CSI-RS based measurements for a serving cell using non-serving panels. Such idle time is defined as an omitted operation time (i.e., an idle time of a certain pre-defined length) in which the network has to apply the scheduling restrictions in the SSBs' symbols to the UE. Note that currently as per the RAN4 requirements, the network must apply scheduling restrictions in all SSB symbols for all UEs in FR2 at any time (i.e., worst case scenario).
