| 摘要 |
Methods are disclosed of a wireless communication receiving device comprising Nr reception antennas and first and second wireless communication transmitting devices comprising, respectively, Nt1 and Nt2 transmission antennas. The wireless communication receiving device and is adapted to simultaneously receive a first MU-MIMO signal from the first wireless communication transmitting device over a first channel and a second MU-MIMO signal from the second wireless communication transmitting device over a second channel. The wireless communication receiving device determines a number (less than or equal to Nt1Nt2) of channel association values, wherein the channel association values are extractable from a correlation between the first channel and the second channel, and transmits an indication of the channel association values to at least one of the first and second wireless communication transmitting device. The first (and/or second) wireless communication transmitting device obtains the indication of the channel association values, determines a number of precoding coefficients based on the channel association values and a maximum available transmission power, generates a MU-MIMO signal based on the precoding coefficients, and transmits the MU-MIMO signal to the wireless communication receiving device. |
