Abstract
A method for use in selecting a cell or cells, from amongst a set of cells in a cellular wireless network, for coordinated use in multi-cell multiple-input/multiple-output (MIMO) transmission so as to reduce feedback overhead, each cell of the said set having at least one MIMO channel characteristic which may vary with time at a measurable rate, comprises a cell selection process comprising the steps of: identifying a cell or subset of cells of the said set for which the time variation rate/rates of the said MIMO channel characteristic is/are the slowest of those of the cells in the said set; and selecting a cell or cells for use in multi-cell MIMO transmission from only the cell or subset of cells identified in the identifying step.
