Abstract
A method and apparatus are provided that can combine the benefits of beamforming with transmit diversity. In one embodiment, the invention includes 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 an antenna array, sampling the signal received from the remote radio at elements of at least one additional antenna array, and deriving spatial parameters for transmitting a signal to the remote radio from the at least one additional antenna array. The invention further includes generating diversity parameters for transmitting a signal to the remote radio using each antenna array as an element of a diversity array, and transmitting a signal to the remote radio using the spatial parameters and the diversity parameters.
