1. A method of controlling a traffic channel data transmission rate of a mobile station in a wireless communication network, the method comprising:
- providing a forward common power control channel for power controlling a plurality of mobile stations, said forward common power control channel being divided into a plurality of frames, with each frame including a plurality of power control groups and each power control group including a plurality of power control slots, each power control slot configured to carry a power control bit;
replacing the power control bits in selected power control slots with traffic channel rate control information; and
transmitting said traffic channel rate control information to one or more mobile stations on the selected power control slots on the forward common power control channel.

Abstract
A radio base station performs reverse link rate control in a wireless communication network by “stealing” bits on a forward common power control channel. The forward common power control channel is divided into a plurality of frames, with each frame including a plurality of power control groups and each power control group including a plurality of power control slots. The radio base station may dynamically select power control slots depending on user demand to be used for reverse link rate control.

17. A radio base station in a wireless communication network comprising:
-
a receiver to receive signals over a traffic channel from one or more mobile stations at variable traffic channel data transmission rates; a transmitter configured to transmit traffic channel rate control information to said one or more mobile stations to control said traffic channel data transmission rates of said mobile stations in selected power control slots on a forward common power control channel, said forward power control channel being divided into a plurality of frames with each frame having a plurality of power control groups and each power control group having a plurality of power control slots, each power control slot configured to carry a power control bit; and a controller communicatively connected to said transmitter and said receiver, and configured to; determine what traffic channel rate control information to transmit; and replace the power control bits in the selected power control slots with the traffic channel rate control information for transmission to the one or more mobile stations. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A mobile station in a wireless communication network comprising:
-
a transmitter to transmit signals over a traffic channel at variable data transmission rates; a receiver configured to receive traffic channel rate control information from a radio base station in selected power control slots on a forward common power control channel, said forward power control channel being divided into a plurality of frames with each frame having a plurality of power control groups and each power control group having a plurality of power control slots, each power control slot configured to carry a power control bit, and wherein the power control bit in the selected power control slots have been replaced with the traffic channel rate control information; and a controller communicatively connected to said transmitter and said receiver to vary the traffic channel data transmission rate of said transmitter responsive to said traffic channel rate control information. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
