The upcoming generations of wireless communications are characterized by a wide variety of applications. This necessitates a provision of flexible radio access technologies (RATs) capable of adapting to changing user (and network) requirements. One of the most significant development in this regard is the introduction of mixed or multiple numerology concept for the fifth generation (5G) of wireless communication. However, flexibility offered by the mixed numerology concept comes with its own set of challenges, including the novel type of interference referred to as inter-numerology interference (INI). This chapter looks at the various implementation-related issues for 5G’s mixed numerology systems such INI in particular. In addition to discussing the analytical models of INI, mechanisms for its mitigation are also described. Moreover, the generalization of numerology concept to other domains is briefly explored for future communication networks.
