Abstract

The relaying is the most important feature as a practical solution in LTE technologies to improve performance and to extend coverage. This paper contributes to the performance on cut-through forwarding mode in relaying framework for applying in TD-LTE standard referred to as 3GPP release 10 and above, it provides lower forwarding latency per hop by rescheduling the alignment of sub-frame duration between each superordinate relay node and subordinate relay node. We demonstrate a significant performance improvement through simulation, the results show that the proposed scheme features lower forwarding latencies for both uplink and downlink in terms of one-way end-to-end delay as compared to legacy synchronous relaying of the relay enhanced TD-LTE networks.
