Abstract: A cooperation MIMO transmitting or receiving method is disclosed. A master terminal calculates a first signal to interference plus noise ratio (SINR), which is SINR between the mater terminal and a base station or between the master terminal and another cluster, and the master terminal calculates a second SINR, which is SINR between a slave terminal and the master terminal. Here, the master terminal forms a cluster with the slave terminal when the second SINR is higher than the first SINR.
