Abstract: A communication system and method for single-point transmission and reception and coordinated multi-point transmission and reception are provided. The system and method include determining information associated with a channel status of a target terminal. The system and method also include selecting, with respect to the target terminal, one of single-point transmission and reception and coordinated multi-point transmission and reception based on the information associated with the channel status of the target terminal.
