Query: Cloud Cognitive Radio HetNets with Limited Feedback   In this paper we propose a cloud based interweave cognitive radio HetNets
which combines gain of cloud based radio that is increased rate for cell edge
users and better spectral efficiency of cognitive radio. Simulation results for
limited feedback shows approximately 100 % increase in rate for primary while
300 % for secondary cell edge users with same outage in cloud over conventional
cognitive radio network.
