可开闭异构网络同信道干扰建模及覆盖性能关键技术研究

This project aims to co-channel interference modeling and coverage performance key technologies for ON\OFF heterogeneous networks (Hetnets). The other-cell co-channel interference of ON\OFF Hetnets is modeled using moment generating function joint Laplace algorithm. Also, the equivalent uniform-density plane-entity (EUDPE) method is taken to calculate the multilayer interference. Besides, the distribution model of signal to interference and noise ratio (SINR) is established for ON\OFF Hetnets. Furthermore, the associate regional relations are analyzed. The test platform will be built and the field test will also be made for ON/OFF Hetnets. Combined with EUDPE method and base station distribution, the special models are proposed for calculating the coverage probability, and the coverage effects brought by increasing base stations are evaluated. Then, the utility problem on base station distribution and coverage will be solved. On this basis, using the moment generating function theory, the analysis of ergodic rate is derived for ON\OFF Hetnets, and the general calculation method is gotten. Finally, the rate calculation problem in load-aware and offloading will also be solved for ON\OFF Hetnets.
