POWER CONTROL METHOD FOR CS OVER HSPA

摘要

In a method and mobile station for transmitting speech data using a speech codec enabled to code coding speech data at varying speech rates, the transmission power is set in a power controlstate in response to a current signal quality measure and in a rate control state wherein speech transmission is controlled by switching the speech rate in response to the signalqualitymeasure and the transmission power is kept essentially constant Using the method will prevent power control based on the signal quality such as the SIR target when instead it would be better to reduce the used transport block size, i.e. reduce the speech codec rate. As a result of the improved use of radio resources, the voice capacity of a cellular system can be increased, while maintaining speech quality.
