Method for controlling power and a transmission rate of a shared forward link data channel in a mobile communication system

A method for controlling a transmission rate of a shared forward link data channel for performing multicasting in a mobile communication system, the method comprising the steps of:

• initializing a virtual transmission rate for each mobile terminal with which the shared forward link data channel is established;
• receiving transmission rate request information from each mobile terminal to adjust the virtual gain of each mobile terminal;
• selecting a lowest transmission rate among the adjusted virtual transmission rates as a control transmission rate value of the shared forward link data channel;
• and
• regulating the transmission rate of the shared forward link data channel to the selected control power value.

A method for controlling a transmission rate of a shared forward link data channel for performing multicasting in a mobile communication system, the method comprising the steps of:

• transmitting, at a base transceiver station, data transmission rate information of the shared forward link data channel to mobile terminals with which the shared forward link data channel is established;
• receiving, at each of the mobile terminals, the data transmission rate information to detect a data transmission rate allocated to each of the mobile terminals;
• and
• maintaining, at each of the mobile terminals, a state in which reception is possible based on the detected data transmission rate.

A set of instructions on a computer readable medium for controlling power of a shared forward link data channel for performing multicasting in a mobile communication system, the comprising:

• a first set of instructions for initializing a virtual gain for each mobile terminal with which the shared forward link data channel is established;
• a second set of instructions for receiving power control request information from each mobile terminal to adjust the virtual gain of each mobile terminal;
• a third set of instructions for selecting a largest virtual gain among the adjusted virtual gains as a control power value of the shared forward link data channel;
• and
• a fourth set of instructions for regulating the power of the shared forward link data channel to the selected control power value.
