摘要：
The standardization of the Long Term Evolution (LTE) of 3G networks is currently carried through in 3GPP. With the deployment of frequency planning, the coexistence issue between TDD and FDD LTE systems is becoming urgent in certain frequency bands. In this paper, the detailed LTE system interference environment is investigated, including single system scenario and inter-system interference, network deployment, propagation models, power control scheme, Adjacent Channel Leakage power Ratio (ACLR) model and link level model. Typical coexistence scenarios with two LTE systems deployed in macro cellular networks are simulated and analyzed. The discussion includes the influence of several system parameters on network performance, such as power control sets, system bandwidths and occupied frequency bands. Meanwhile, the possible approach of adopting beam-forming technology or inter-cell interference coordination mechanism is also investigated in TDD-LTE systems of coexisting cases. The simulation results show that two LTE systems could coexist with proposed advanced techniques under current LTE Radio Frequency (RF) System parameters.
