Relaying has been proposed to support users suffering from high shadowing or high interference and therefore being not able to receive high data rates. With adaptive relaying, a higher Modulation and Coding Scheme (MCS) can be used which increases the feasible data rate. The investigation of relaying techniques widely concentrates on information theoretical methods. Instead, this paper focuses on system level simulations to exploit the achievable results within a realistic environment. The question which relaying methodology is the best choice if unicast and an multicast transmissions are possible is investigated. The results show that relaying techniques can improve the median cell throughput and decrease the outage probability in a mixed unicast and multicast environment.
