Abstract:
1. A method of operating a first communication node that communicates by multiple-input-multiple-output (MIMO) wireless communications with a second communication node of a wireless communication system, the method comprising: receiving a sounding reference signal over a plurality of subcarriers transmitted by the second communication node for MIMO communications; measuring a channel quality responsive to the sounding reference signal to output a first channel quality value; receiving a demodulation reference signal over a plurality of subcarriers transmitted by the second communication node for MIMO communications; measuring a channel quality responsive to the demodulation reference signal to output a second channel quality value; determining a reliability of the first channel quality value and a reliability of the second channel quality value; and combining the first channel quality value and the second channel quality value while compensating for a difference between the determined reliabilities of the channel quality values to generate a combined channel quality value based on:
