Abstract
Following the principle of reuse partitioning, this paper proposes two new frequency planning schemes for cellular system with two-hop fixed relay nodes (FRNs). The coverage-oriented scheme is developed with emphasis put on the signal to interference ratio (SIR) experienced by mobile terminals within whole coverage area, while the efficiency-oriented scheme is developed targeting at a higher spectral efficiency. Taking uplink as an example, both simplified analysis and intensive computer simulations are presented to offer comparison among FRN enhanced systems with our proposed schemes, that with a known channel-borrowing based frequency planning scheme and the conventional cellular system without relaying. Our studies show that the FRN enhanced system with our coverage-oriented scheme provides the largest worst-case SIR, while that with our efficiency-oriented scheme offers a remarkably higher spectral efficiency
