摘要

An apparatus comprising: a plurality of radio ports for interconnection with radio circuits, a plurality of antenna ports for interconnection with antennas, interconnection circuitry configured to enable interconnection of each of one or more radio ports to different non-overlapping sets of P antenna ports, where P is controllable and P=2^p, p being a whole number; and at least one control port configured to receive a control signal for determining P.
