Power controlling method and corresponding base station
First Claim
1. A power controlling method for controlling transmission power of user terminals operating in a virtual MIMO transmission, the method comprising:
- determining a respective transmission power of respective user terminals of the plurality that makes a sum of transmission powers of the respective user terminals of the plurality minimum under a condition that a respective specific index for respective user terminals meets a required threshold value; and
feeding back the respective determined transmission power to the respective user terminals.

Abstract
A power controlling method and corresponding base station for controlling the transmission power of each user terminal are disclosed, in which, each user terminal is paired into virtual MIMO transmission. In the solution, first, determining the transmission power of each user terminal that makes the sum of the transmission power of each user terminal minimum under the case that the specific index for each user terminal meets a required threshold value; then, feed backing the determined transmission power of each user terminal to each user terminal. Compared with the prior art, the solution can achieve a preferable power efficiency.
