Title:
アップリンクパワー制御方法及びシステム
Document Type and Number:
Japanese Patent JP5663660
Kind Code:
B2
Abstract:
A method for controlling uplink power is disclosed in the present invention. The method includes: a base station configuring and sending a target received power parameter corresponding to a standard service rate, a path loss compensation factor parameter and a enabled deltaMCS parameter of adjusting transmitted power according to a Modulation Coding Scheme (MCS) grade to a terminal; subtracting target received power and a path loss compensation quantity from a limit value of the transmitted power of terminal to obtain power margin, and determining an available MCS grade of the terminal according to the power margin and sending the available MCS grade to the terminal. A system for controlling the uplink power is also disclosed in the present invention. In the present invention, a structure of the system is simple, which supports an adaptive selection for the suitable MCS grade ofUE, and implements uplink power control correctly and effectively.
