Introduction: Challenges in 5G+HetNet Integration
The current developments in the fifth generation and beyond (5G+) mobile networks focus on moving from the increasingly congested radio frequencies (RF) to higher frequency bands such as millimeter wave (mmWave), Terahertz, and Visible Light bands. Among

Preface
Integration of high-frequency air interfaces into 5G and beyond (5G+) wireless networks can release the congested Radio Frequency (RF) band and support the increasing demand for high data rates. This requires utilization of new communication bands such as millimeter wave (mmWave), terahertz, and visible light. The aforementioned high-frequency bands, however, present challenging wave propagation characteristics that call for special measures to ensure their efficient integration within the 5G+ heterogeneous networks (HetNets). This brief investigates planning and operational challenges of 5G+ HetNets and presents via
