Provided is a method for efficiently performing a communication operation using supplementary information. A communication method in an integrated terminal which communicates through communication modems corresponding to base stations of various communication systems includes reading a communication network information file which is updated and is included in the integrated terminal and performing the communication operation based on the read communication network information file.

Integrated terminal using supplementary information and communicating method thereof

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.
