Abstract
A method and apparatus are provided for selecting transmission parameters for multiple transmit antenna arrays. In one embodiment, the invention includes receiving a signal from a remote radio, measuring the transmit coherency of the received signal, selecting, based on the transmit coherency, whether to apply coherent combining to signals transmitted to the remote radio using each of two transmit antenna arrays to each form a beam to coherently combine with each other beam upon receipt by the remote radio, selecting, based on the transmit coherency, whether to apply transmit diversity to signals transmitted to the remote radio using each of the two transmit antenna arrays as diversity antennas. The embodiment further includes determining signal transmission parameters to apply to the two antenna arrays for transmissions to the remote radio based on the selections, and transmitting a signal to the remote radio from the two transmit antenna arrays by applying the determined signal transmission parameters to the two transmit antenna arrays.
