“…However, although user efficiency is clearly improved due to the increased link SIR, this is not necessarily enhancing the cell achievable throughput which is captured by ̅ because of the tradeoff between reducing outage probability and increasing the throughput. The studies in the literature [1][2][3][4][5][6][7][8][9][10][11] don't distinguish between the two values and use the first one while, in fact, the second one is closely related what is expected to be achieved in practice. …”

“…The results in that reference show that a noticeable coverage improvement can be obtained by all three schemes almost equally; this gain diminishes in the case of NLOS relay channel. In [4], different reuse schemes and path selection rules were considered in the study of resource management policies of two-hop networks. The results indicate that full intra-cell reuse or partial reuse can improve the performance.…”

“…Their results show a throughput enhancement with no significant impact on system coverage. [7] proposed a frequency partition scheme as [4] which doesn't allow for intra-cell reuse; throughput based relay selection was assumed.…”

Relays are being adopted as a cost effective solution to improve the coverage of cellular networks and provide ubiquitous service to all users. To meet the growing demand for mobile data, we need to improve radio resources reuse capability. Partitioning of radio resources is a common practice in cellular network as it provides a simple and reliable way to distribute the resources over systems nodes. The reuse factor of one is hard to achieve in legacy cellular systems; with relaying and with adopting OFDMA and Adaptive Modulation and Coding (AMC) technologies, we will try to achieve this goal by partitioning the radio resource over the relays within a single cell and efficiently reuse them. Some reuse schemes are proposed and studied along with other schemes presented in the literature. The tradeoff between outage performance and throughput enhancement is studied and the impact of power control, the number of hops and reuse capability is considered.
