Flexible outer Reed-Solomon coding on RLC layer for MBMS over GERAN

In this work, we present the multimedia broadcast multicast services (MBMS) framework for GSMEDGE radio access network (GERAN). Flexible outer Reed-Solomon coding is introduced in the GERAN MBMS environment. Performance estimations are presented. These performance estimations are used to compare the flexible RS coding scheme with simple repetition schemes. It is shown that at a target C/I of 7.5 dB and a maximum throughput of 40 kbit/s can be supported. Applying the flexible Reed-Solomon coding we also show that, e.g. for a C/I of 15 dB, even more than 90 kbit/s can be supported by MBMS.
