Abstract
Techniques to combine soft-decision power control symbols received for multiple active base stations. In one method, a received signal is initially processed to derive soft-decision (multi-bit valued) symbols for power control commands transmitted from a number of base stations. Each soft-decision symbol for each base station is then scaled based on a scaling factor associated with the base station and which is related to the received signal quality for the power control symbols for the base station. The scaling allows power control symbols for more reliably received base stations to be given greater weights. The scaled soft-decision symbols for each power control period are then combined to provide a decision metric for the period. Each decision metric is then compared against a particular threshold, and a power control decision is derived for each decision metric based on the result of the comparison.
