Method and apparatus for communicating with blind interference alignment using power allocation and/or transmission architecture

A wireless communication system comprising:

• a plurality of receivers, 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, wherein each receiver shifts between the plurality of antenna modes in a predetermined receiver-specific manner;
• and
• a plurality of base stations to perform transmission, wherein each base station in the plurality of base stations has one or more transmitters operating a total of at least two transmit antennas and being operable to communicate with one or more of receivers in the plurality of receivers using a blind interference alignment (BIA) scheme in which each transmitter in a base-station generates a stream based on data intended for one or more of the receivers without using channel state information and in which only one antenna is active at each receiver during a given time slot, and further
• wherein each of the plurality of base stations comprises a power allocation unit to adjust transmit power of symbols of BIA-encoded user streams.
