Abstract

This invention discloses a power control method in a portable Internet system used in controlling data transmission output on the mobile communication system using the adaptive modulation and coding list(AMC) in the mobile communication network using the AMC plan, which includes modulation grades for transmitting data on the mobile communication system and required power information based on the grade, the power control method includes: a, utilizing the AMC plan to set a maximum required power of the power corresponding to the modulation grade distributed to the mobile system along with the data output on the system, b, comparing the BER happened in the data transmission with the critical one, c, when the BER is smaller than the critical one, it reduces data output in a preset interval, d, when it is greater than that, it increases the data output in a preset interval and e, when they are equal, the data output maintains at the current state.

Description

technical field [0001] The present invention relates to a method and device for controlling power in a portable Internet system, and more particularly, to a method and device for controlling power in a portable Internet system, which can be achieved by using adaptive modulation and coding (hereinafter Herein, an AMC scheme is used to control data transmission output on a mobile communication system, and the AMC scheme uses an AMC table including a modulation level for transmitting data on the mobile communication system and requested power information according to the modulation level, And relates to a power control scheme for additionally applying a Bit Error Rate (hereinafter referred to as BER) to the AMC scheme in a mobile communication network using the AMC scheme. Background technique [0002] With the rapid development of computer, electronics and communication technologies, various wireless communication services using wireless networks are provided. The most basic ...
