<p>A method of non-coherent detection of the number of cell-specific transmit antenna ports for a communications device, includes the steps of, at the communications device: (a) generating a downlink reference signals (RS) sequence replica; (b) for a first possible transmit antenna port only, determining a downlink system bandwidth from non-coherent correlation of the generated downlink RS sequence replica and received RS samples; (c) at the determined downlink system, performing a correlation of the generated downlink RS sequence replica and received RS samples for each of a plurality of possible transmit antenna ports; and (d) determining the number of transmit antennas from a comparison of the correlation results in step (c).</p> |
