Dynamic spectrum access and sharing can improve spectrum efficiency in 5G, if mechanisms for optimizing the coexistence of network entities are provided. For this reason, interoperability schemes, such as offloading and handover, and interference mitigation techniques, are crucial in many 5G scenarios, and must be jointly optimized through context awareness and cognitive radio approaches. This project investigates the challenge of coexistence in 5G, analyzing research and standardization activities regarding context-aware interoperability and interference mitigation mechanisms. An analysis on the 3GPP ANDSF and the IEEE 802.21 standards, for interoperability, and IEEE 1900.6, for cognitive radio and spectrum sensing, will be carried out, and a platform for their integration, indicated as cognitive media independent access network selection, and referred to as C-MIANS, will be proposed, designed, and implemented.
