Abstract
The present invention discloses a method for uplink multi-user cooperation communication, including a first, and a second source node and a target node. When transmitting a signal to the target node, the first source node also transmits the signal to the second source node, the second source node changing to a relay node of the first source node and forwarding the signal to the target node; the target node obtains its reception Signal Noise Ratio (SNR) by using a maximal ratio combining mode according to the signal directly transmitted from the first source node and the signal forwarded from the second source node, sets a precoding policy according to the reception SNR, and selects the optimal precoding as a precoding vector which is used when the first source node transmits a signal to the target node.
