METHOD AND APPARATUS FOR TRANSMITTING CHANNEL STATUS INFORMATION EFFICIENTLY IN A MULTI-CARRIER WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a wireless communication system, and more particularly, discloses a method and apparatus for transmitting channel status information efficiently in a multi-carrier wireless communication system. A method for transmitting channel status information in a multi-carrier wireless communication system, according to one embodiment of the present invention, may include: receiving, at a receiving terminal, signals transmitted on N (N‰¥2) number of carriers from a transmitting terminal to the receiving terminal; determining, at the receiving terminal, channel status information for each of the N number of carriers from the received signals; and transmitting the channel status information for each of the N number of carriers on M (1‰¤M‰¤N) number of carriers from the receiving terminal to the transmitting terminal. The channel status information for each of the N number of carriers may be transmitted according to a channel status information reporting period for each of the N number of carriers and a channel status information reporting period offset.
