Title:
直交周波数分割多重接続方法を使用する無線通信システムにおいて基地局の電力増幅器消耗電力制御方法及び装置
Document Type and Number:
Japanese Patent JP6419921
Kind Code:
B2
Abstract:
A power control method of a base station in a wireless communication system based on Orthogonal Frequency Division Multiple Access (OFDMA) is provided for reducing power consumption by turning off the bias of the power amplifier for the duration of a symbol carrying no user data. The method includes checking scheduling information of radio resources, detecting a symbol carrying no user data, based on the scheduling information, and turning off a bias of the power amplifier for a symbol duration of the symbol carrying no user data. The transmission power control method is capable of reducing power consumption of the base station by turning off the bias of the power amplifier of the base station for the symbol duration in which no user data is transmitted.
