Abstract: This work proposes a three-dimensional (3D) reference model for multiple-input multiple-output (MIMO) base station to relay station (BS2RS) Rician fading channels. First, the new stochastic reference model, based on the geometrical one-sphere model, is obtained under the assumption that both base station and relay station are stationary while an infinite number of local scatterers around the RS move in random directions. Then, the closed-form spatial and temporal correlation functions between each two sub-channels are derived in the 3D non-isotropic scattering environment, and a detailed discussion is also made to demonstrate their properties. Finally, we find that our proposed channel model can cover several communication scenarios (e.g., fixed-to-mobile (F2M) and fixed-to-fixed (F2F) scenarios, etc.), and make a detailed simulation to illustrate the property of our proposed model.
