1. A method of wireless communication, comprising:
receiving, by a user equipment (UE) of a wireless communication network, conditions for sweeping beams between a base station of the network and the UE, the conditions comprising:
a beam sweeping trigger rule,
a beam measurement configuration for measuring at least one characteristic of each of the beams on downlink;
a beam sweeping enabled/disabled flag, and
a beam sweeping origin flag indicating either the UE or the base station as an origin of sweeping;
measuring, by the UE, at least one characteristic of each of the beams in accordance with the measurement configuration;
after the measuring, detecting, by the UE, a trigger in accordance with the trigger rule; and
in response to detecting the trigger, sweeping, by the UE, the beams on uplink based on the measuring, and only upon the beam sweeping enabled/disabled flag indicating beam sweeping enabled, and the beam sweeping origin flag indicating the UE as the origin of sweeping.
