MU-MIMO which simultaneously transmits to multiple STAs has been researched for the future wireless communication systems. Conventionally AP transmits to STAs while mitigating inter-stream interference by transmit beamforming when the total number of STA antenna is less than AP antenna number. As the background to STA antenna number increases, this paper assumes that the total number of STA antenna is more than AP antenna number. Since the degree of freedom of AP antenna is insufficient in this environment, it is not possible to mitigate inter-stream interference by transmit beamforming. Thus, in this paper, we present a method which AP assigns the receive weight of each STA, and calculates the transmit weight in consideration of the receive weights as MU-MIMO method in the above environment. Then, we clarify their effectiveness by comparing with MU-MIMO with antenna selection. |
