Abstract

Communication rate in a variable rate communication system is determined by calculating metrics based upon symbol energy over a traffic channel frame (200) and selecting an optimum rate based upon the calculated metrics. The metrics are calculated by selectively accumulating symbol energy, using adders (405-408) and accumulators (409-412) in response to the presence of power control groups (201) within the traffic channel frame (200), as determined by power control group selector (400).
