Figure 3From: Content aware optimization for video delivery over WCDMAClosed-loop power control in WCDMA. The slow outer loop sets an SIR target by comparing the estimated BLER with a target BLER, whereas the fast inner loop adjusts the transmit power to match the SIR target. The estimated BLER and SIR at the base station are used in the outer loop and inner loop, respectively.Back to article page
