The Long Term Evolution (LTE) have two standards of FDD and TDD.The FDD has large coverage area,but it has high resource occupation.The TDD has larger capacity and abundant spectrum resource.In order to meet user’ s superior experience of high?speed Internet,the fusion networking of TD?LTE and LTE FDD has become a key problem.In this paper,the feasibility of fusion networking of TD LTE and LTE FDD is proved by analyzing such aspects as LTE FDD and TD?LTE key technology,frame structure, physical architecture and terminal equipment.
