CONTROL METHOD, RADIO COMMUNICATION SYSTEM, RECEIVER, AND TRANSMITTER

摘要

PROBLEM TO BE SOLVED: To provide a method of controlling radio channel capable of promptly coping with changes in propagation environment of radio channel, and to provide a receiver thereof. SOLUTION: In a method of controlling radio channel in the direction from a transmitter to a receiver in a radio communication system having the transmitter and the receiver, the receiver generates electric power control information that directs up and down of transmission electric power to the transmitter based on receiving conditions of the radio channel from the transmitter to the receiver. The receiver also generates information showing a rate matching coefficient applied to the radio channel from the transmitter to the receiver as transmission parameters. While the receiver transmits electric power control information and transmission parameters to the transmitter, the transmitter controls the radio channel directed from the transmitter to the receiver based on electric power control information and transmission parameters.
