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; receiving a rate control parameter from at least one of a serving base station and a non-serving base station, wherein if 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 if the rate control parameter is received from the non-serving base station, the rate control parameter comprises a fourth control state, the fourth control state indicating an instruction to decrease the first data transmission rate; determining a second data transmission rate of the terminal as being a decreased data rate relative to the first data transmission rate when the rate control parameter received from the non-serving base station includes the fourth control state indicating the 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 any rate control parameter that is received from the non-serving base station does not include the fourth control state indicating an instruction to decrease the first data transmission rate; further comprising: transmitting data on a reverse packet data channel (R-PDCH) at a rate which does not exceed the second transmission data rate.
