There is provided a wireless communication method for use in a MIMO system, the system having a first cell adjacent to one or more second cells, each cell being served by a base station and having a plurality of fixed or mobile subscriber stations, and each base station having MIMO channels between its cell and each subscriber station in its cell, the method comprising: recognising an opportunity for a reduction of interference experienced between a particular subscriber station in a particular said second cell and the base station of the first cell; selecting as the basis of interference reduction a rank deficient MIMO channel amongst the MIMO channels between the base station of the first cell and each subscriber station in the first cell; and applying post-coding to transmissions on the selected MIMO channel, where the selected MIMO channel is an uplink channel, or on a MIMO uplink channel corresponding to the selected MIMO channel, where the selected MIMO channel is a downlink channel, to reduce the interference experienced by the base station of the first cell. |
