BEAM SWITCHING AND ENHANCED BEAM REPORTING TO MITIGATE INTERFERENCE IN BEAMFORMING

Abstract:

Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive a first beamformed transmission associated with a directional beam from another UE. The UE may measure a main lobe or at least one side lobe associated with the directional beam, and determine a level of interference at the UE based on the measuring. One or more of the main lobe or the at least one side lobe associated with the directional beam may cause interference to a second beamformed transmission associated with another directional beam from a base station. The UE may transmit a beam report including an indication of the main lobe or the at least one side lobe associated with the directional beam causing the interference to the second beamformed transmission associated with the other directional beam from the base station.
