Abstract
Relaying is seen as a cost-effective solution to increase the coverage and improve the capacity for LTE-A networks. However, the resource allocation among different nodes and links and inter-cell interference coordination (ICIC) are important challenges in order to make the most of the potential benefits of relay deployments. This paper focuses on Type 1 half-duplex inband relaying. Several strategies related to radio resource partition and frequency reuse between nodes and links are proposed for various relay deployments. Modified FFR-based resource sharing schemes for ICIC are proposed for both access and backhaul subframes, jointly considering the impact of the number and location of relays on the sector. The real impact of the capacity of the backhaul link on system performance is explicitly taken into account. In addition, relay cell range expansion with several bias offsets is analyzed.
