HetNets are seen as new network paradigm evolutions to the fifth-generation wireless systems, which can cost-efficiently improve system coverage, capacity, latency, and so on.
Historical Background
With the explosive increase in mobile data traffic, operators have to continuously improve network performance. As a promising solution, the HetNet is a new technology that can cost-efficiently improve system coverage and capacity (Peng et al., 2015a). Communication nodes with high transmit power, such as MBSs, are deployed for large coverage and high capacity, while LPNs, such as SCAPs, help to supply service in the coverage of some hotspots. By deploying additional LPNs within the local-area range and bringing LPNs closer to end-UEs, HetNets can potentially improve spatial resource reuse and extend the coverage, thus allowing future cellular systems to achieve higher data rates while retaining the uninterrupted connectivity and seamless...
