5G
The wireless industry has already been preparing for the emerging fifth-generation (5G) standards in recent years. A 5G system is featured by (1) addressing the demands and business contexts of 2020 and beyond, (2) creating an access network to enable a fully mobile and interconnected society, (3) providing massive amount of miscellaneous devices with the connections to packet data network, and (4) bearing huge volume of data services in the manner of a deeply heterogeneous system. 5G achieves higher speed, increased capacity, decreased latency, and better quality of service (QoS). One of the promising technologies to meet the above requirement is the small cell network (SCN), which allows short-range, low-power, and low-cost base stations operating in conjunction with the main macrocellular network infrastructure. SCN introduces additional heterogeneity to wireless communication system, and thus, the so-called self-organizing network (SON) technology has been extensively studied to overcome the challenges.
