1. A method, comprising:
determining, from an indication that an initial uplink beam between a user equipment and a network node is misaligned with respect to a downlink beam between said network node and said user equipment, at least one misalignment angle between said initial uplink beam and said downlink beam, wherein the indication comprises at least a reduction in gain received by the network node, and wherein the at least one misalignment angle is determined by mapping the reduction in gain to prestored information comprising a plurality of misalignment angles; and
reconfiguring said uplink beam based on said misalignment angle to produce a reconfigured uplink beam.
