1. A method comprising:

  • sampling a signal received from a remote radio at elements of an antenna array;

    deriving spatial parameters for transmitting a signal to the remote radio from a first transmit antenna array using the samples;

    sampling the signal received from the remote radio at elements of at least one additional antenna array;

    deriving spatial parameters for transmitting a signal to the remote radio from a second transmit antenna array using the samples of the received signal at the additional antenna array;

    receiving feedback signals from the remote radio;

    generating diversity parameters for transmitting a signal to the remote radio using the first and second transmit antenna arrays as diversity antennas based on the received feedback; and

    transmitting a signal to the remote radio from the first and second transmit antenna arrays using the spatial parameters and the diversity parameters.
