METHOD AND APPARATUS FOR TRANSMITTING CHANNEL FEEDBACK INFORMATION IN A WIRELESS COMMUNICATION SYSTEM AND METHOD AND APPARATUS FOR RECEIVING CHANNEL FEEDBACK INFORMATION IN A WIRELESS COMMUNICATION SYSTEM

摘要

The invention relates to a method (MET-T) for transmitting channel feedback information in a wireless communication system. The method (MET-T) contains the steps of determining (M1/5) a first reception quality value (CQI 1) for a first radio channel from a first transmission point (2a) of the radio communication system to an apparatus (4), determining (M1/7) based on the first reception quality value (CQI 1) a preferred use of the first radio channel (6a), and transmitting (M1/8) towards the first transmission point (2a) the first reception quality value (CQI 1) and the first reception quality value (CQI 1) simultaneously indicates the preferred use. The invention further relates to an apparatus for transmitting channel feedback information in the wireless communication system and to a method (MET-R) and apparatus (8) for receiving the channel feedback information in the wireless communication system.

1. A method for transmitting channel feedback information in a wireless communication system, said method comprising:
determining a first reception quality value for a first radio channel, determining at least a second reception quality value for at least a second radio channel, determining based on said first reception quality value and further based on said at least second reception quality value a preferred use for one of said first radio channel and of said at least second radio channel, wherein said preferred use is a size of feedback radio resources for transmitting at least one pre-coding matrix indicator for said first radio channel, and transmitting channel state information comprising said first reception quality value and said at least one pre-coding matrix indicator,wherein said first reception quality value simultaneously indicates said size of feedback radio resources for transmitting said at least one pre-coding matrix indicator.
