Beam management systems and methods

Abstract:

A UE RX beam training procedure in which a user equipment (UE) is configured such that the UE selects a UE RX beam based not only on a measurement of a first reference signal (RS1) transmitted using a first TX beam, but also based on a measurement of a second reference signal (RS2) transmitted using a second TX beam. For example, the UE may be provisioned with "interference" information indicating one or more reference signals that the UE should consider as interference. An advantage with these proposals is that the UE RX beam can be determined not only on maximizing received power, but also by taking predicted interference in to account, which can lead to a higher quality of service and/or a higher throughput.
