Method and apparatus for controlling uplink power to maintain desired frame error rate in a wireless communications system |
摘要 |
In the absence of a continuous channel from the mobile terminal (301) that incorporates a CRC in each transmitted frame from which the base station (303) can derive a power control signal for feedback to the mobile station for maintaining the mobile station's pilot Eb/N0 level at a desired target that corresponds to a particular frame error rate, the pilot signal received by the base station from the mobile terminal itself is arranged in a frame format. Each pilot frame is compared with an a prioi known transmitted pilot signal bit pattern to determine whether it has been received in error. In response to a comparison of a received pilot frame with the expected known bit pattern of the pilot frame, an error signal is derived, which in the described embodiment is either a step-up or step-down signal that is fed back to the mobile terminal to increase or decrease its transmitted pilot Eb/N0 level, respectively. |
