Abstract

We introduce a new interference management technique for wireless cellular networks when the base station (BS) has K antennas and there are M mobile stations (MS), each with a single antenna. Our interference management scheme takes advantage of multiuser diversity to transmit K independent data streams to K out of M mobile stations. The new approach achieves the dirty paper coding (DPC) capacity of K log log(M) as M tends to infinity. Surprisingly, the new scheme does not require full channel state information (CSI) and needs only close to K integers related to CSI are fed back to the transmitter. Moreover, the encoding and decoding of the new scheme is significantly simpler than existing MIMO schemes and is similar to point-to-point communications.
