Abstract:
A UE determines a beam coherence interval metric that is a measure of stability of a beam pair over time based on a set of beam coherence intervals measured by the UE. The beam pair comprises a UE receive beam and a base station transmit beam. A beam coherence interval comprises a time duration within which a quality of a signal received on the UE receive beam remains within one of a plurality of signal quality bins. The UE reports the metric to the base station. The base station may update beam management resource and reporting configurations to the UE based on the metric. The UE may also use the metric to determine a hysteresis value useable by the UE to decide to switch from an active receive beam to a different receive beam having a higher signal quality by at least the hysteresis value.
