Abstract:
1. A method of controlling data transmission rate in a terminal used in a wireless communication system comprising a network, the method comprising: providing data to the network at a first data transmission rate; transmitting, to the network, a status information bit on a reverse link to permit generation of a rate control parameter based upon the status information bit; receiving, at the terminal, the rate control parameter from each of a serving base station and a non-serving base station, and wherein when the rate control parameter is received from the serving base station, the rate control parameter comprises a first, second, or third control state, the first control state indicating an instruction to increase the first data transmission rate, the second control state indicating an instruction to decrease the first data transmission rate, and the third control state indicating an instruction to maintain the first data transmission rate, and wherein when the rate control parameter is received from the non-serving base station, the rate control parameter comprises a fourth control state; determining a second data transmission rate of the terminal using the rate control parameter received from the non-serving base station when the rate control parameter received from the non-serving base station includes the fourth control state which indicates an instruction to decrease the first data transmission rate; and determining the second data transmission rate for the terminal using the rate control parameter received from the serving base station as long as the rate control parameter that is received from the non-serving base station does not include the fourth control state which indicates the instruction to decrease the first data transmission rate.
