POWER DISTRIBUTION METHOD AND DEVICE FOR MULTIPLE DATA STREAMS TRANSMISSION

摘要

A power distribution method and device for multiple data streams transmission. The method includes the steps: a channel quality indication CQI value of a data stream reported by a terminal is received (S101); a linear value of the power distributed to each data stream is obtained according to CQI value by using water pouring algorithm (S102); the power is distributed to the data stream according to the linear value of the power of each data stream (S103). The invention can be configured to distribute different power to data stream according to channel quality of different data stream so as to increase channel capacity. A larger capacity gain can be obtained under medium and low noise-signal ratio by comparing with the method using average power distribution.
