METHOD FOR IMPLEMENTING A FUNCTION OF CLOSED LOOP TRANSMITTING DIVERSITY ON THE DEDICATED CHANNEL

WIPO Patent Application WO/2004/045108

A1

The present invention discloses a method for implementing a function of closed loop transmitting diversity on the dedicated channel, which comprises: decomposing the weighting factor of every antenna into a phase complex multiplication coefficient and a power offset term , obtaining the power offset value A&lowbar dB by the conversion of power offset term, and said phase complex multiplication coefficient is the complex number of which both real part and imaginary part are ±1 or 0; phase-modulating the framing data by using the phase complex multiplication coefficient ; getting a power amplitude value by using said power offset value A&lowbar dB, and then using the obtained power amplitude value, transmitting the phase-modulated framing data in step B via the corresponding antenna, thereby implementing the weighting function of closed loop weighting factor for downlink dedicated channel. According, this invention can simplify greatly the chip design, and satisfy preferably the accuracy requirement when occupying less the chip resource.
