Patent ID: 8446867

Claim:
A method of controlling uplink power in a wireless communication system, the method comprising: receiving a power control offset with respect to a data burst including user data from a base station; receiving a power control offset with respect to a control burst including control information from the base station; and controlling transmission power of the data burst and transmission power of the control burst according to the power control offset with respect to the data burst and the power control offset with respect to the control burst, wherein the transmission (P new(Data) ) of the data burst is expressed by the equation shown below: P new(Data) =P last +( C/N new −C/N last )−10 log 10 ( R new )−10 log 10 ( R last ))+Offset Data wherein P last is transmission power of a previously transmitted data burst, C/N new is a carrier-to noise ratio with respect to a determined modulation scheme, C/N last is a carrier-to-noise ratio with respect to a previously used modulation scheme, R new is the number of repetitions with respect to the determined modulation scheme, R last is the number of repetitions with respect to the previously used modulation scheme, and Offset Data is an accumulation of power control offsets with respect to the data burst.
