1. An apparatus comprising:
at least one processor; and
at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
determine which of a first group of radio frequency paths for antenna elements of an array of antenna elements are transmission radio frequency paths to be used for transmission and which of a second group of radio frequency paths for the antenna elements of the array of antenna elements are reception radio frequency paths to be used for reception, wherein the second group comprises at least one or more radio frequency paths that are different from the first group of radio frequency paths, wherein the array of antenna elements comprises a one or two-dimensional array of the antenna elements that is positioned on a single surface or a single edge of the apparatus, and wherein a transmission steering beam direction and a reception steering beam direction of the array are configured to not deviate by more than a threshold; and
control when to use the determined transmission radio frequency paths for transmission and the determined reception radio frequency paths for reception.
