  • Method and apparatus for synchronization control of forward link transmitting power during soft handoff in wireless communication systems
    Patent number: 7194281
    Abstract: The present invention relates to a method and an apparatus for synchronization control of forward link transmitting power during soft handoff, comprising: collecting the current transmitting power TX(i) of the forward links and the current reception quality of the reverse links; selecting the best base station BTS(x), recording and storing TX(x) reported by BTS(x), marking the BTS(x) as the base station with strong reverse link and the others as base stations with weak reverse link; sending the reverse link flags, TX(x) and the number of base stations involved in soft handoff to all base stations; determining whether a base station is the base station with weak link according to the flag from the base station controller; calculating the deviation between the current transmitting power TX(i) and the TX(x) if the base station is with weak link; adjusting the power control parameters and repeating the above steps; the parameters of the reception quality in reverse links are sampled for every frame in the inventi
