| Abstract | This paper applies user cooperation with network coding in MBMS (Multimedia broadcast/multicast service). MBMS uses Raptor codes which cannot overcome the tradeoff among bandwidth expansion, user perceived quality of service (QoS) and erasure correction performance. Therefore user cooperation together with network coding is proposed to support broadcast/multicast services in the future mobile communication networks to save bandwidth and to improve user perceived QoS without degrading erasure correction performance. The proposed approach is tailored to LTE networks being fully standard compliant. The simulation results show that local retransmissions can save up to 80% redundant information on the cellular link as long as there are at least two cooperative mobile devices. The results also show that network coding can save more than half of the traffic in the short-range link as long as there are four devices in the cooperation cluster. |
