METHOD AND APPARATUS FOR OPERATING UPLINK AMC IN MOBILE COMMUNICATION SYSTEM

摘要

A method for a serving base station determining a modulation and coding selection (MCS) of a terminal in a wireless communication system, according to the present invention, comprises the steps of: determining uplink interference from neighboring cells; determining a signal-to-interference plus noise ratio (SINR) based on a reply signal indicating whether data transmitted by the terminal is successfully received and the interference information; and determining the MCS based on the SINR information and the reply signal. According to the present invention, an MCS level can be determined according to a channel status of a receiver by accurately determining interference from nearby cells, thereby improving data transmission/reception efficiency.
