To provide cellular systems with additional spectral resources, the wireless industry is considering the aggregation of frequency carriers in licensed, unlicensed, and Shared Access (SA) bands. In this paper, the authors focus on reliable Carrier Aggregation/Channel Bonding (CA/CB) techniques, in which when CA/CB between the licensed, unlicensed and SA carriers is performed, the licensed carrier is used for the primary and secondary carriers, and the unlicensed and SA carriers are operated as additional secondary carriers. They provide a taxonomy of the use of CA/CB in cellular networks and highlight the differences between different CA/CB approaches.
