Claim Text:
1. An open loop power control method, wherein in a collaborative-multiple input multiple output Co-MIMO system, a base station performs power control, and the method comprises: obtaining an initial power allocation ratio of an edge user, and receiving a first signal to interference plus noise ratio (SINR) sent by the edge user at the initial power allocation ratio; calculating a first power allocation ratio of the edge user according to the first SINR, determining a greater power allocation ratio A between the initial power allocation ratio and the first power allocation ratio, and receiving a second SINR sent by the edge user at the power allocation ratio A; determining a target value between the first SINR value and the second SINR value as a third SINR; and calculating a second power allocation ratio of the edge user according to the third SINR, determining a greater power allocation ratio B between the initial power allocation ratio and the second power allocation ratio, and adjusting signal transmit power according to the power allocation ratio B.
