1. A method for operating a wireless communication device comprising a plurality of physical antennas, the method comprising:
receiving, by the wireless device, information on a first sounding reference signal port to support the transmission of an uplink sounding reference signal using a single antenna port mode, wherein the single antenna port mode uses antenna virtualization to realize a single antenna port by transmitting from at least two of the plurality of physical antennas;
receiving, by the wireless device, information on a set of second sounding reference signal ports, each one of the second sounding reference signal ports supporting the transmission of said uplink sounding reference signal using a respective one of the plurality of physical antennas;
selecting, by the wireless device, a sounding reference signal port from said first sounding reference signal port and said second sounding reference signal ports; and
transmitting by the wireless device to a base station, said uplink sounding reference signal using said selected sounding reference signal port.
