Abstract

Fifth Generation (5G) communication networks support multiple radio access technologies, popularly known as multi-RAT, to facilitate services to all the mobile subscribers irrespective of their subscription for any old generation network. Unique interleaver assignment to each active mobile subscriber within intra-RAT communication is comparatively easy task. However, the same becomes a challenging issue when multi-RAT supported communication is required to be dealt with. This paper reveals a theoretical backend control signaling solution to overcome this challenge. The proposed solution is named as Store-Regenerate-Recall (SRR) technique for interleaver assignment in multi-RAT supported 5G network. This solution is quite effective and easy-to-implement for handling interleaver assignment issue at the 5G network end in multi-RAT scenarios without any subscriber identity clash. Overall, the method is of great significance when multi-carrier multi-RAT solutions are intended to be developed for 5G networks.
