The goal of SOLDER is to develop a new spectrum overlay technology, which will provide the efficient aggregation of non-continuous dispersed spectrum bands licensed to heterogeneous networks (HetNets) and heterogeneous Radio Access Technology (h-RATs).
Within 5GNOW SOLDER IS-Wireless was responsible for radio resource management, scheduler implementation and MAC layer design implementation and system-level simulations.
Design of Carrier Aggregation scheduler for LTE. THe scheduler got integrated with the branch of the popular SDR-based OpenAirInterface LTE stack from Eurecom. The scheduler allows for parametrization of objectives (maximizing throughput, fairness, minimizing latency). The scheduler has been described here
