Abstract:
1. A method operable in a secondary station in a network, the secondary station comprising: a transceiver adapted for simultaneously receiving transmissions from a first primary station controlling a first cell and transmissions from a second primary station controlling a second cell, the method causing the secondary station to execute the steps of: (a) selecting a first precoding matrix from a primary set of precoding matrices associated with the first cell, (b) selecting a subset of precoding matrices from a secondary set of precoding matrices associated with the second cell, the subset of precoding matrices consisting of at least one precoding matrix, wherein said subset of precoding matrices are dependent upon the selected first precoding matrix in accordance with a precoding scheme, (c) selecting a second precoding matrix from of the selected subset of precoding matrices, and (d) transmitting a first indicator representative of the first precoding matrix.
