Patent ID: 8213533

Claim:
A method of transmitting information signals to two or more User Equipment (UE) from a Distributed Antenna System comprising a plurality of geographically distributed, non-co-located antennas, each connected to a central CPU via backhaul, the method comprising: assigning a non-zero power allocation weight to each of two or more geographically distributed, non-co-located antennas using power allocation weights that maximize one of the minimum UE information rate or minimum UE average Signal to Interference and Noise Ratio (SINR), under per-antenna power constraints; encoding information signals to two or more UEs using a space-time or space-frequency code; and transmitting the encoded information signals to each of the two or more UEs from each of the two or more geographically distributed, non-co-located antennas, the information signals weighted at each antenna by the non-zero power allocation weight assigned to that antenna.
