Relay node cell area is limited by low transmission power and limited antenna capabilities, which may not allow it to carry a significant share of the traffic load, thus reducing its efficiency. Cell range extension is thus expected to better balance the load in the network, hence, improving the performance of relay deployments. Herein, we investigate two relay cell range extension techniques, introducing...
Deploying relay nodes is foreseen a cost-efficient solution to combat the severe propagation loss at cell edge. However, relay cell coverage is limited by the low transmit power, limited antenna capabilities and wireless backhaul link bottleneck which may lead to load imbalances and hence low resource utilization efficiency. Further challenges in relay deployments are attributed to increased interference...
