The next generation of mobile-enabled wireless networks, known as 5G networks, is announced to be deployed by 2020. In the 5G framework, access technologies are one of the main features that would allow users to seamlessly connect to the Internet using any of the available technologies. These technologies are going to coexist in the same physical environment. This coexistence has the advantage of offering the user multiple options for establishing communications. On the other hand, existing and upcoming wireless standards have not given this coexistence enough attention. In this paper, we survey existing communication protocols, techniques and mechanisms, as well as features of the 5G communication standards that allow technology to cope well with coexistence. We focus on access layer solutions that can be used in unlicensed frequency bands. We also argue that resource sharing should be extended not only to manage the available spectrum but also the available physical systems. We argue in this paper that resource sharing mechanisms would have a positive impact on the 5G infrastructure for better spectrum efficiency. [ABSTRACT FROM AUTHOR] |
