Method for controlling power and a transmission rate of a shared forward link data channel in a mobile communication system
First Claim
1. A method for controlling power of a shared forward link data channel for performing multicasting in a mobile communication system, the method comprising the steps of:
- initializing a virtual gain for each mobile terminal with which the shared forward link data channel is established;
receiving power control request information from each mobile terminal to adjust the virtual gain of each mobile terminal;
determining a power control value of the shared forward link channel by using the adjusted virtual gains; and
transmitting the shared forward link channel with the determined power control value.

Abstract
A method for controlling power of a shared forward link data channel for multicasting in a mobile communication system. The method includes the steps of initializing a virtual gain for each mobile terminal with which the shared forward link data channel is established, receiving power control request information from each mobile terminal to adjust the virtual gain of each mobile terminal, selecting a largest virtual gain among the adjusted virtual gains as a control power value of the shared forward link data channel, and regulating the power of the shared forward link data channel to the selected control power value.
