| 摘要 |
A method includes receiving in a mobile communication terminal over a communication channel a Multiple-Input Multiple-Output (MIMO) signal that includes at least a transmission addressed to the terminal. A Multi-User Signal to Noise Ratio (MU-SNR) is estimated in the terminal based on the received signal. The MU-SNR is indicative of a power ratio between the transmission addressed to the terminal and remaining components of the signal, which are assumed to include one or more transmissions addressed to one or more other terminals. Feedback, which is indicative of the communication channel and is based on the MU-SNR, is transmitted from the terminal. |
