Abstract: A user equipment device (UE) determines a beam coherence interval metric, which 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 receive beam of the UE and a transmit beam of a base station transmitting to the UE. 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 also determines a hysteresis value based on the beam coherence interval metric and uses the hysteresis value to decide to switch from an active receive beam to a different receive beam that has a signal quality higher than the active receive beam by at least the hysteresis value. Alternatively, the base station determines and sends the UE the hysteresis value.

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.

Abstract: A user equipment device (UE) reduces receive beam selection time. An antenna array forms receive beams to receive synchronization signal blocks (SSBs) transmitted by a base station (BS). Each SSB comprises OFDM symbols. Each SSB includes a BS-assigned index. The receive beams are switched in time such that, for each SSB, two or more of the receive beams are used to receive corresponding two or more mutually exclusive sets each having at least one but less than all of the OFDM symbols of the SSB. A processor is programmed to, for each receive beam/SSB index pair, measure a signal quality based on the at least one but less than all of the OFDM symbols of the indexed SSB received by the receive beam of the pair. The processor uses the measured signal qualities to select one of the receive beams to use to receive subsequent communications from the BS.
