A method of selecting a cell or cells for use in multiple-input/multiple-output (MIMO) transmission to user equipment or a relay station in a serving cell of a cellular wireless network, there being a set of N cells of the cellular network from which a selection of cells is to be made, N being an integral number greater than one and the set including the serving cell, the received signal power of the serving cell and the received interference power of the other cells in the set relative to the serving cell are sorted in descending order of power P, such that P0≧P1≧ . . . ≧PN-1, and a group of M cells are selected from the said set of N cells, where the cells selected are those giving the smallest value of M for which the inequality ∑ k = 0 M - 1  P k ≥ &bgr;  ∑ i = 0 N - 1  P i is satisfied, &bgr; being a first decision threshold parameter. |
