Executive Summary

The authors consider the problem of UpLink (UL) scheduling in relay-assisted Long Term Evolution (LTE) networks and propose a Buffer-based Channel dependent Scheduler (BCS) for the same. Their objectives are to minimize packet loss due to buffer overflow and increase resource utilization efficiency while ensuring fairness among users. This is achieved by utilizing the Buffer Status Report (BSR) available in Third Generation Partnership Project (3GPP)-LTE. The proposed scheduler comprise three-phases. Phase I partitions the resources between eNB (Base Station in LTE) and Relay Nodes (RNs) while Phase II, between different RNs.
