LBNEs (Long baseline Neutrino Oscillation Experiment) have promised to be a very powerful experimental set up to study various issues related to Neutrinos. Some of them are, to resolve mass hierarchy, CP violation in lepton sector, among others. But, they are crippled due to presence of some parameter degeneracies, like the Octant - degeneracy. A longbaseline experiment is being planned, at USA, from FNAL (Fermilab National Accelerator Laboratory) to an underground laboratory at Homestake in South Dakota, at an angle of 5.84 degrees from FNAL (at a baseline of 1289 km). In this work, we first show the presence of Octant degeneracy in FNAL-LBNE, and then combine it with Daya Bay Reactor experiment, with the help of simulation, at different values of CP violation phase. We show that the Octant degeneracy in LBNE can be resolved completely with this proposal.
