Carrier Aggregation has been included in 4G systems such as 3GPP LTE-Advanced to allow the utilization of larger (up to 100MHz) and fragmented spectrum. Aggregation is happening at the MAC layer and each carrier is using the same PHY layer. Further, given the nature of LTE, each of these carriers must use a licensed frequency band. In the SOLDER project we will go further by aggregating heterogeneous radio access technologies with potentially different spectrum access schemes such as unlicensed or light-licensed. This is an important step towards fulfilling the requirements of spectrum hungry 5G systems. This paper presents the scenarios, vision and possible technical solutions envisioned in the SOLDER project.
