Abstract:
1. A machine-implemented method for removing interference between adjacent multiuser (MU) multi antenna system (MU-MAS) clusters comprising: detecting signal strength at a first client from a first MU-MAS cluster; detecting interference signal strength at the first client from a second MU-MAS cluster; if the signal strength from the first MU-MAS cluster reaches a specified value relative to the value of the interference signal strength from the second MU-MAS cluster, then generating channel state information (CSI) defining channel state between one or more antennas of the first client and one or more antennas of the second MU-MAS cluster; and implementing MU-MAS precoding at a base transceiver station (BTS) in the second MU-MAS cluster based on the CSI to reduce RF interference at the first client.
