Abstract

A system and method for communicating with a second communication system utilizing a plurality of antennas. Various aspects of the present invention may comprise determining whether communicating with the second communication system utilizing a plurality of antennas in a first configuration, which comprises a beam-forming configuration, is preferable to utilizing a plurality of antennas in a second configuration, which comprises a MIMO or MISO configuration. If it is determined that the first configuration is preferable to the second configuration, the communication system may be configured to communicate with the second communication system by utilizing at least a portion of the plurality of antennas in the first configuration. If it is determined that the second configuration is preferable to the first configuration, then the communication system may be configured to communicate with the second communication system by utilizing at least a portion of the plurality of antennas in the second configuration.
