Abstract
Methods for transmitting a first signal x1 and a second signal x2 using a first array of antenna elements of a polarization A and a second array of antenna elements of a substantially orthogonal polarization B. The methods include transmitting x1 in a first beam generated with array size invariant beamforming, using a sub-array A1 of antenna elements from the first array and applying a first precoding matrix, and using a sub-array B1 of antenna elements from the second array and applying a second precoding matrix. The methods also include transmitting x2 in a second beam generated with array size invariant beamforming, using a sub-array A2 of antenna elements from the first array and applying a third precoding matrix, and using a sub-array B2 of antenna elements from the second array and applying a fourth precoding matrix. The sub-arrays within a polarization are typically non-overlapping.
