Abstract

The invention provides a method for determining a D2D network model and a method for evaluating the performance of the D2D network model, and the coverage probability of the D2D user and the cellularuser in the network and the area frequency spectrum efficiency of the D2D network can be improved. The method for determining the D2D network model comprises modeling the cellular network as a poissonpoint process based on a heterogeneous network in which the cellular user and the D2D user coexist; setting an isolation ring around the macro base station, so that the D2D user located in the isolation ring cannot reuse the resources of the cellular user, and modeling the clustered D2D network in a mode of combining the poisson hole process with the Thomas clustering process to obtain the D2D network model based on the poisson hole cluster process. The method is suitable for the field of D2D heterogeneous network deployment.

Description

technical field [0001] The present invention relates to the field of heterogeneous network deployment, in particular to a method for determining a D2D network model and a method for evaluating the performance of a D2D network model. Background technique [0002] As an important part of 4G and future 5G networks, Device-to-Device (D2D) communication can not only reduce the transmit power of terminals, increase the regional spectrum efficiency of cellular systems, but also solve the problems of wireless communication networks through in-band communication. Due to the lack of spectrum resources in the medium and low-end networks, unloading the traffic of the cellular network has great development prospects in the future communication network. [0003] For the modeling of the D2D network, the position of the D2D transmitter is modeled as a spatially homogeneous Poisson point process, and the distance between the D2D receiver and the corresponding transmitter is fixed. Fixing th...
