Abstract:
An apparatus and a method for configuring antenna arrays for scalable radio frequency (RF) architecture are disclosed. A subset of antenna arrays are grouped into K groups and a receive or transmit weight vector is applied to each of the antenna arrays in each of the K groups. A channel response is measured for each of the antenna in the K groups. The response is summed for each group and complex scaling factors are calculated based on the summed response. Based on the scaling factors the antenna weight vectors are updated and the updated weight vectors are applied to the antenna arrays. The steps of grouping the antennas and refining the weight vectors are performed till the antenna weight vectors reach a steady point, i.e. the current antenna weight does not improve the beamforming gain by a predetermined threshold in comparison to the previous antenna weight.

Claim (Index 16):
A method for refining transmit antenna weights, the method comprising:\n grouping the transmit antennas into a first plurality of antenna groups, each antenna group of the first plurality of antenna groups comprising a subset of the transmit antennas; applying a transmit antenna weight vector to each antenna group, the transmit antenna weight vector specifying for each antenna in a given antenna group, a magnitude and phase gain to apply to a signal transmitted by each antenna in the given antenna group; obtaining a measured response for each of the antenna groups, from the receiver, when transmitting a training signal and applying the transmit antenna weight vectors; updating the antenna weight vectors for the group of transmit antennas; and applying the updated antenna weight vectors to the group of transmit antennas.
