Partial Information Relaying is a novel cooperative communication technique in which a relay forwards only partial information of the received data. By reducing the amount of forwarding data in cooperating phase, fast forwarding is made possible. Hence, it enables to increase an overall rate to adapt to instantaneous channel gains. To realize this method, the transmitted signal from source is divided into two layers - basic layer which is transmitted from source to destination directly and superposition coding (SC) layer via source-relay-destination link. In this paper, we study how to apply this scheme in a cooperation model with multiple relays and destinations. We propose several ways for forwarding the signals at a relay and show that under different channel gains, solving an optimization problem is an efficient way to achieve a better overall rate than a conventional Partial Information Relaying scheme.
