REPORTING DOWNLINK REFERENCE SIGNALS ASSOCIATED WITH MULTIPLE ANTENNA PANELS

Abstract:

A base station may transmit one or more reference signals to a user equipment (UE) to measure. However, the base station is typically limited to configuring one downlink reference signal per antenna panel of the UE. This can reduce network efficiency because the base station has to switch downlink reference signals in order to switch antenna panels. Techniques and apparatuses described herein allow a UE to transmit a report that includes a plurality of measurements of a downlink reference signal corresponding to a plurality of antenna panels and/or to transmit a report that includes one or more measurements of a plurality of downlink reference signals from an antenna panel. The base station may therefore map a downlink reference signal to a plurality of antenna panels of the UE. Accordingly, the base station is able to switch antenna panels without switching downlink reference signals.
