Power controllable wireless mobile communication system of adaptive modulation and coding scheme and its method therefor

摘要

A power controllable wireless mobile communications system using an adaptive modulation and coding scheme and a method therefor are provided. The power controllable wireless mobile communications system using an adaptive modulation and coding scheme comprises a signal-to-noise ratio (SNR) extracting unit which extracts an SNR from a signal which is processed in a predetermined modulation and coding scheme and received; a modulation and coding scheme determining unit which compares the extracted SNR with a requested SNR that is requested for the received signal, and determines again a modulation and coding scheme reflecting conditions including at least the result of the comparison; a power control value determining unit which compares the extracted SNR with a requested SNR that is requested for a signal of the determined modulation and coding scheme, and determines a power control value according to the result of the comparison; and a signal generating unit which inserts a field indicating the determined modulation and coding scheme and a power control command field corresponding to the power control value, into data to be transmitted, processes the result according to the determined modulation and coding scheme and generates a transmission signal.
