N2 - With coexistence of primary and Cognitive Radio (CR) networks, the benefits of Non-selfish Symbiotic Cognitive Relaying (NSSCR) were illustrated in previous work by considering single cognitive radio user (CRU) cooperation. However, with cooperation from multiple CRUs instead of a single CRU, additional degree of diversity gain as well as power gain can be achieved. Thus, in this paper a Multiuser Non-Selfish Symbiotic Cognitive Relaying (MNSCR) is further proposed for the coexistence of primary and CR networks. In a symbiotic architecture, the PU (PU) with weak channel quality will initiate a full duplex amplify-and-forward (AF) cooperative transmission from multiple CRUs. As a reward, the PU would like to give an incentive time for CR data transmission. Instead of utilizing incentive time duration immediately by selfish CRUs who participated in the cooperation, the non-selfish CRUs might selflessly give incentive time duration to a CRU with a better channel quality. Simulation results shows that with proposed MNSCR the capacity of CR network can be further improved.
