A method (MET-T) for transmitting channel feedback information in a wireless communication system, said method (MET-T) comprising the steps of: - determining (M1/5) a first reception quality value for a first radio channel from a first transmission point of said radio communication system to an apparatus, - determining (M1/5) at least a second reception quality value for at least a second radio channel from at least a second transmission point of said wireless communication system to said apparatus, - determining (M1/7) 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 (M1/8) to a central unit adapted to control the first transmission point and the at least second transmission point channel state information comprising said first reception quality value and said at least one pre-coding matrix indicator, wherein said size of said feedback radio resources is implicitly signaled from a mobile station (10, 24) comprising said apparatus to said central unit by applying a predefined mapping table at said mobile station (10, 24) and at said central unit; wherein said size of said feedback radio resources depends on fulfilling one of at least two reception quality conditions of said mapping table; wherein said one of said at least two reception quality conditions is a predefined difference value for a relative reception quality that is defined by a difference between a third reception quality for a joint reception of said first radio channel and said at least second radio channel and said first reception quality value. characterized in that said first reception quality value and said difference value simultaneously indicate said size of feedback radio resources for transmitting said at least one pre-coding matrix indicator for said first radio channel. - determining (M1/5) a first reception quality value for a first radio channel from a first transmission point of said radio communication system to an apparatus, - determining (M1/5) at least a second reception quality value for at least a second radio channel from at least a second transmission point of said wireless communication system to said apparatus, - determining (M1/7) 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 (M1/8) to a central unit adapted to control the first transmission point and the at least second transmission point channel state information comprising said first reception quality value and said at least one pre-coding matrix indicator, wherein said size of said feedback radio resources is implicitly signaled from a mobile station (10, 24) comprising said apparatus to said central unit by applying a predefined mapping table at said mobile station (10, 24) and at said central unit; wherein said size of said feedback radio resources depends on fulfilling one of at least two reception quality conditions of said mapping table; wherein said one of said at least two reception quality conditions is a predefined difference value for a relative reception quality that is defined by a difference between a third reception quality for a joint reception of said first radio channel and said at least second radio channel and said first reception quality value.
