abstract : A heterogeneous network (HetNet) based on the long-term evolution advanced standard hasbeen developed to improve the system performance; in this HetNet, macrocells and lowpowernodes, such as picocells, coexist. Further, cell range expansion has been introduced toencourage data offloading in a HetNet. In this paper, we propose a cell selection schemebased on the signal-to-interference-plus-noise ratio to achieve an optimal offloading effect.We also propose a resource allocation scheme in the frequency and time domains, to reduceinterference in a HetNet. In the frequency domain, the macrocells allocate a frequency bandby using soft frequency reuse, and the picocells choose the sub-bands that are not used inthe macrocell sector, to avoid interference. In addition, we found that it was difficult to allocatea limited frequency resource. Therefore, the cross-tier interference can be managed by usingan almost blank subframe (ABS) with a flexible ABS ratio, to improve spectrum efficiency inthe time domain. The simulation results show that the proposed schemes can improve thespectrum efficiency of both the macro-user equipment and the pico-user equipment, as wellas improve the overall UE performance.
