The allocation of the transmission joint architecture, as well as by the interference alignment method using the power allocation and user assignment code that is optimized, a method for MU-MIMO efficient transmission

摘要

A method for operating a BIA code structure in the system, to obtain a device and a wireless communication system. A radio communication system of an embodiment comprises a plurality of receivers, each receiver has a multi-mode antenna having a single radio frequency (RF) chains is operable in a plurality of antennas modes , each receiver varies between a plurality of antennas modes in a predetermined manner. Wireless communication system includes a plurality of base stations in the cell topology for performing downlink transmission to multiple receivers, each base station has one or more transmitters, one or more transmitters there is operable and multi-user MIMO includes a transmitting antenna to communicate with one or more of (MU-MIMO) based blind interference alignment (BIA) using the method multiple receivers, each active base station, to operate the BIA code structure equal at a given transmission resources. .FIELD 2B
