Abstract:
A method for performing forward power control in a code division multiple access (CDMA) cellular communication system, comprising the steps of:initializing and starting the forward power control;establishing a maximum transmission gain, a minimum transmission gain and a nominal transmission gain, being between the minimum and maximum transmission gains; andadjusting a forward link transmission gain (forward gain) of a power transmitted from a base station to a mobile station based on a value of an erasure indicator bit contained in a reverse traffic frame transmitted in a reverse traffic channel from the mobile station,wherein when the forward gain is between the nominal transmission gain and the maximum transmission gain, upward adjustments to the forward gain are for a first specified value, and when the forward gain is between the minimum transmission gain and the nominal transmission gain, upward adjustments to the forward gain are for a second specified value, the second specified value being greater than the first specified value.
