Abstract
Aspects of the present disclosure provide for beam management in wireless communication systems. In some examples, beam angle information (e.g., angles of arrival/departure) may be utilized to select one or more serving downlink beams for communication between a scheduling entity and a scheduled entity. The beam angle information may further be utilized to facilitate additional operations within a backhaul network, such as wireless node locating, obstacle locating, system mapping within the network topology, beam determination and beam sweeping configuration, and mobility management among wireless nodes of a backhaul network. In other examples, aperiodic uplink beam measurements may be triggered based on downlink beam measurement reports and/or in response to a request from a scheduled entity. The scheduling entity may then jointly select uplink and downlink beams based on both the received downlink beam measurement report and uplink beam measurements.
