| Summary: | Heterogeneous Networks (HetNet) comprise
networks with specially designed architecture. To cover large
areas, established base stations (macro sites) are used; for coating
buildings, microcells are employed; for covering individual levels
or floors in a building, Pico-cells are utilized; and finally for
providing wireless coverage to individual apartments, small
offices, and home based businesses, femtocells (HeNodeBs) are
exploited. The goal behind the implementation of HetNets
involves incrementing the capacity, modifying spectrum use,
lowering the capital and operating costs, as well as offering
steady user-based experience of network architecture.
Furthermore, HeNodeBs have been developed for voice, data,
video services in home and offices and a certain outdoor scenario
with a very limited geographical coverage. However, these
random HeNodeB deployments raises co-tier and cross-tier intercell
interference which results system performance degradation.
The existing approaches have tried to solve Inter-cell
Interference (ICI) issues. Yet, these techniques are become
unsatisfactory for recent communications as aggressive
frequency reuse is desired to maintain high data-rates. In this paper, we investigated and identified recent issues of inter-cell interference coordination problems. The related schemes and techniques are also analyzed in order to highlight the pros and cons of each of the schemes. Besides, the qualitative and the quantitative analysis of these techniques are also presented. |
