Abstract

In a communication system, a mobile terminal compares a first modulation/Forward Error Correction (FEC) rate level, which is a modulation/FEC rate level used in a previously transmitted signal, with a second modulation/FEC rate level, which is a modulation/FEC rate level to be used in a currently transmitted signal. If the second modulation/FEC rate level is higher than the first modulation/FEC rate level, the mobile terminal determines the transmission power using a normalized Carrier to Noise ratio (C/N) corresponding to the second modulation/FEC rate level on an ascending normalized C/N table, while if the second modulation/FEC rate level is lower than the first modulation/FEC rate level, the mobile terminal determines the transmission power using a normalized C/N corresponding to the second modulation/FEC rate level on a descending normalized C/N table.
