Feedback generation method and system for uplink transmit power control
First Claim
1. A feedback generation system for an uplink Transmit Power Control (TPC), the feedback generation system comprising:
- an uplink information receiver to receive uplink information from a terminal, to measure a Signal-to-Interference Noise Ratio (SINR) value with respect to the received uplink information, and to measure a movement speed of the terminal;
an adjusted SINR calculator to calculate an adjusted SINR value, based on an expected SINR value and the measured SINR value; and
a feedback information regenerator to regenerate feedback information based on a transmission power adjustment value and the adjusted SINR value, and to transmit the regenerated feedback information to the terminal,wherein the transmission power adjustment value is set in small units when the terminal is moving at a high speed, andthe transmission power adjustment value is set in large units when the terminal is moving at a low speed.

Abstract
A feedback generation method for uplink Transmit Power Control (TPC) in a mobile communication system is provided. A feedback generation system for uplink TPC includes an uplink information receiver to receive uplink information from a terminal, to measure a Signal-to-Interference Noise Ratio (SINR) value with respect to the received uplink information, and to measure a movement speed of the terminal, a transmission power adjustment value setting unit to set a transmission power adjustment value based on the movement speed of the terminal; an adjusted SINR calculator to calculate an adjusted SINR value, based on an expected SINR value and the measured SINR value; and a feedback information regenerator to regenerate feedback information based on the transmission power adjustment value and the adjusted SINR value, and to transmit the regenerated feedback information to the terminal.
