In order to handle the cross-tier and co-tier interference effectively for LTE-A two-tier heterogeneous network, we propose a CSGC algorithm based partial spectrum sharing scheme using cognitive radio (CR) technique. In this paper, Radio resources are divided into three parts: macro-dedicated part, shared part and femto-dedicated part. Simulation result shows that the proposed scheme not only solves...
In order to handle the cross-tier interference problem and improve the throughput of a long-term evolution advanced (LTE-A) heterogeneous network, we propose a downlink partial spectrum sharing scheme using cognitive radio (CR) technique. In this paper, radio resources are divided into three parts: macro-dedicated portion, shared portion and femto-dedicated portion. Moreover, we propose a mixed sharing...
