Abstract

Provided are a power controllable wireless mobile communication system using an adaptive modulation and coding scheme and a method thereof. The power controllable wireless mobile communication system adopting an adaptive modulation and coding scheme includes a signal-to-noise ratio (SNR) extraction unit, a modulation and coding scheme decision unit, a power control value decision unit and a signal generation unit; the signal-to-noise ratio (SNR) an extraction unit for extracting the SNR from a signal processed and received according to a predetermined modulation and coding scheme; the modulation and coding scheme decision unit for comparing the extracted SNR with a desired SNR required for the received signal, and again determining a modulation and coding scheme that reflects conditions including at least comparison results; the power control value decision unit is used to compare the extracted SNR with the required SNR required for signals of the determined modulation and coding scheme, and determine according to the comparison result Power control value; the signal generation unit is used to insert the field indicating the determined modulation and coding scheme and the power control command field corresponding to the power control value into the data to be transmitted, process the result according to the determined modulation and coding scheme and generate transmit a signal.

Description

technical field [0001] The present invention relates to a power controllable wireless mobile communication system using an adaptive modulation and coding scheme and a method thereof, and more particularly, to a method for using adaptive modulation and The device and method for controlling the output power of the mobile station in the power controllable wireless mobile communication system of the coding scheme, the signal-to-noise ratio is extracted from the reverse signal transmitted by the mobile station to the base station. Background technique [0002] Generally speaking, in a wireless communication system, the ultimate goal of power control is to provide a predetermined quality communication channel by compensating for signal attenuation in the wireless channel, so that the signal can be received by the receiving end with an appropriate signal strength. Meanwhile, as wireless communication networks have been developed into cellular networks, power control has become an i...
