Ultra-densification and increased bandwidth are promising 5G technologies envisaged for meeting the ever-increasing mobile traffic demands. Deploying complementary small cells operating in the higher frequency bands on an existing macro layer operating on the traditional lower frequency band is recognized as a very attractive solution for providing high capacity and seamless ubiquitous coverage. However, existing small cell discovery mechanisms are tailored for the macro layer and using them will lead to an increase in the user equipment (UE) energy consumption and consequently an increase in the generated electromagnetic field (EMF). This chapter summarizes various small cell discovery mechanisms that are designed for an energy-efficient and EMF-efficient discovery of the small cells. It further presents a framework for evaluating the optimal small cell discovery periodicity which also leads to the reduction in the generated EMF in a 5G heterogeneous network.
