Claim:
1. An apparatus for wireless communication, comprising: a plurality of antennas, configured to communicate a Multiple-Input Multiple-Output (MIMO) signal; a master baseband integrated circuit (BBIC), which is configured to process a first component of the MIMO signal that is communicated via a first subset of the plurality of the antennas; and a slave BBIC, which is configured to process a second component of the MIMO signal that is communicated via a second subset of the plurality of the antennas, wherein the master BBIC is further configured to control the slave BBIC so as to jointly communicate the MIMO signal, based on the first and second components, via the entire plurality of the antennas, and wherein the master BBIC and the slave BBIC are configured to jointly transmit the MIMO signal using a beamforming or spatial expansion matrix that spans the entire plurality of the antennas, by:
