Abstract:
In this paper, we propose a resource allocation scheme in the frequency and time domain, to reduce interference in the Heterogeneous Network (HetNet) scenario. In the frequency domain, the macrocell allocates frequency band by using Soft Frequency Reuse (SFR), and the picocell chooses sub-bands that are not used in the macrocell sector, to avoid interference. In addition, to allocate the limited frequency resource is difficult. Therefore, we can manage the cross-tier interference using Almost Blank Subframe (ABS) in the time domain. Simulation results show that the proposed scheme can improve Signal to Interference plus Noise Ratio (SINR), and the spectrum efficiency of macrocell and picocell users. Eventually, the proposed scheme can improve overall cell performance.
