摘要：
A method, apparatus, and wireless communication system is disclosed herein for operating a BIA code structure in a system. In one embodiment, the wireless communication system comprises a plurality of receivers, wherein each receiver in the plurality having a multi-mode antenna with a single radio frequency (RF) chain that is operable in a plurality of antenna modes, and further wherein each receiver shifts between the plurality of antenna modes in a predetermined manner. The wireless communication system also includes a plurality of base stations in a cell topology to perform downlink transmissions to the plurality of receivers, each base station in the plurality of base stations having one or more transmitters having a transmit antenna and being operable to communicate with one or more of receivers in the plurality of receivers using a multi-user MIMO (MU-MIMO)-based blind interference alignment (BIA) scheme, wherein each active base station in the plurality of base stations operates an identical BIA code structure in a given transmission resource.
