Abstract
In accordance with an example embodiment of the present invention, a method comprising: receiving, by a user equipment of a communication network, a request from a network node to use at least two beam configurations of multiple different beam configurations for the user equipment; measuring, by the user equipment, downlink received power on at least one reference signal using the at least two beam configurations; sending, by the user equipment on an uplink, information of at least two downlink received powers and at least one reference signal using the at least two beam configurations; receiving, by the user equipment, signaling from the network node comprising an indication of beam correspondence assessment from the network node; and adjusting, by the user equipment, uplink beam with reference to a downlink beam based on the received indication of beam correspondence assessment.
