Low power nodes, such as small cells and relays, have been a hot topic in research, standardization, and industry communities, and are typically considered under an umbrella term called heterogeneous networking. In this paper, we look at the problem of finding the optimal ratio between resources allocated for the access and relay links for in-band relays. We present an algorithm that can find the optimal ratio for given input parameters, such as number of relay and mobile stations and their SINR values. We run extensive system level simulations for several deployment scenarios, including a static and mobile case, to show that the proposed algorithm results in better performance when compared to the static resource allocation between the access and relay links.
