Handling dynamic blockage in millimeter wave communication systems
Aspects are provided which handle dynamic blockage of beams transmitted by a base station to UEs in millimeter wave communication. In one aspect, the base station identifies at least two UEs with which the base station has established a link and which may be potentially blocked from the base station by a dynamic blocker such as a moving vehicle. After the potentially blocked UEs are identified, the base station schedules all identified UEs for joint beam training and receives feedback transmitted by the UEs to determine if a dynamically blocked spatial region exists. If a blockage exists, the base station performs a follow-up procedure to avoid the dynamically blocked spatial region and provide coverage for the UEs, for example, by blanking out or not using blocked beams in subsequent beam training and/or by coordinating with a neighbor cell. The base station may thus proactively improve coverage of dynamically blocked UEs.
