The cooperative communication represents the cooperation among the nodes which are participating in communications. It also achieves higher bandwidth efficiency while guaranteeing the same diversity order as that of the conventional cooperative schemes. These schemes discuss the relay selection via available partial Channel State Information (CSI) at the source and the relay nodes. Few of the methods behind the cooperative communications are considered in this paper. Some of the methods such as pure cooperative communication, triple busy tone multiple access mechanism and node selection algorithm, determine the relay nodes which are in the belonging to the network when the source node transmits the message or information to destination node.
