1. A method of wireless communication performed by a network node, comprising:
communicating information associated with one or more phase shift parameters for a beamforming circuit, wherein the beamforming circuit includes a Butler matrix having one or more sets of configurable phase shifters,
wherein the information associated with the one or more phase shift parameters includes information indicating an array gain metric associated with a coverage area of the network node,
wherein the array gain metric indicates a difference between a first array gain associated with an optimized configuration for the one or more sets of configurable phase shifters and a second array gain for a configuration in use at the one or more sets of configurable phase shifters; and
communicating in accordance with the one or more phase shift parameters.
