This paper studies the potential performance im- provement from cooperative diversity transmission in a cellular network. We consider a simpli ed coopera- tive relaying system which allows the mobile terminals to relay data packets from their partners. We obtain numerical results for the outage probability, taking into account log-distance path loss, spatially corre- lated shadowing and small-scale fading. A compari- son with conventional macrodiversity is performed for various scenarios of interest. The simulation results demonstrate the superiority of cooperative diversity transmission.
