APPARATUS AND METHOD FOR SENDING AND RECEIVING CHANNEL STATE INFORMATION IN COMMUNICATION SYSTEM |
摘要 |
The present invention relates to a channel status information transmission/reception method and apparatus in a wireless communication system in which the transmission apparatus generates channel status informations for at least two transmission schemes by combining rank informations corresponding to the transmission schemes into combined rank information through analyzing an uplink channel, and transmits the channel status informations for the respective transmission schemes on up link channel, the channel status information for one of the transmission schemes containing the combined rank information; the reception apparatus receives the channel status informations corresponding to at least two transmission schemes, the channel status information for one of the transmission schemes including combined rank information for the transmission schemes, schedules downlink channel according to the channel status information, and transmits signals on the downlink channel. According to the present invention, the transmission apparatus combines rank informations of a plurality of transmission schemes and feeds back the combined rank information so as to reduce overhead at a reception apparatus. |
