Abstract

A heterogeneous network dynamic system level simulation method based on a physical layer abstraction algorithm aims at heterogeneous network convergence of an LTE cellular mobile communication network and a next-generation high-speed wireless local area network based on a Wi-Fi wireless transmission standard protocol 802.11n, wherein the physical layer abstraction algorithm is used to simplify and abstract link simulation of a complex physical layer into a simple unitary parametric function, details of the physical layer protocol are shielded, and different physical layers of 802.11n and LTE are abstracted into a uniform air interface model to be used as an across-layer module. The heterogeneous network dynamic system level simulation method based on a physical layer abstraction algorithm, provided in the invention, implements dynamic system level simulation and greatly lowers computation complexity.

Problems solved by technology

[0003] The problem to be solved by the present invention is: in the current wireless communication, on the one hand, the system is extremely complex for the heterogeneous network formed by the fusion of 802.11n and LTE; System-level simulation requires a huge amount of calculation data and extremely high complexity. Therefore, it is even more difficult to perform system-level simulation on the heterogeneous network formed by the fusion of 802.11n and LTE.
