A method for providing communication from a first communication device over a multiple-input-multiple-output, MIMO, wireless channel to a second communication device in a closed loop MIMO communications system, the method comprising: receiving a feedback transmission at the first communication device from the second communication device, wherein the feedback transmission includes a precoding matrix selection from the second communication device; generating a representation of a speed of the second communication device relative to the first communication device based on a Doppler shift of the feedback transmission, from the second communication device, received at the first communication device, wherein the Doppler shift of the feedback transmission below a Doppler selection threshold indicates that the speed of the second communication device is below a selection threshold, and wherein the Doppler shift of the feedback transmission above the Doppler selection threshold indicates that the speed of the second communication device is above the selection threshold; responsive to the representation of the speed of the second communication device indicating a speed that is greater than the selection threshold, selecting a common precoding matrix that is different than a precoding matrix indicated by the precoding matrix selection from the second communication device; and responsive to selecting the common precoding matrix, transmitting the transport data block from the first communication device over the MIMO wireless channel to the second communication device, wherein the transmission of transport data blocks from the first communication device using the common precoding matrix is continued until a next feedback transmission, including a next precoding matrix selection from the second communication device, is received. receiving a feedback transmission at the first communication device from the second communication device, wherein the feedback transmission includes a precoding matrix selection from the second communication device; generating a representation of a speed of the second communication device relative to the first communication device based on a Doppler shift of the feedback transmission, from the second communication device, received at the first communication device, wherein the Doppler shift of the feedback transmission below a Doppler selection threshold indicates that the speed of the second communication device is below a selection threshold, and wherein the Doppler shift of the feedback transmission above the Doppler selection threshold indicates that the speed of the second communication device is above the selection threshold; responsive to the representation of the speed of the second communication device indicating a speed that is greater than the selection threshold, selecting a common precoding matrix that is different than a precoding matrix indicated by the precoding matrix selection from the second communication device; and responsive to selecting the common precoding matrix, transmitting the transport data block from the first communication device over the MIMO wireless channel to the second communication device, wherein the transmission of transport data blocks from the first communication device using the common precoding matrix is continued until a next feedback transmission, including a next precoding matrix selection from the second communication device, is received.
