Joint Performance Analysis And Mode Selection For Full-duplex Device-to-device Communications:a Stochastic Geometry Approach

With the explosive growth of wireless devices and cellular network services,we are experiencing the shift towards the 5th-generation cellular network,which can provide high-rate,high-efficiency,and high-quality cellular network services.And in the evolution of the 5th-generation communication network,Device-to-Device(D2D)communication,Full-duplex communication,and Small Base Station(SBS)can reuse the cellular spectrum resources,which can potentially increase the cellular communication performance,moreover,the average transmit rate,network capacity and spectrum efficiency can be improved.In this paper,we conduct the performance analysis of multi-tier heterogeneous cellular network supporting D2 D and Full-duplex.Based on the analysis results,we study the improvement of cellular network performance by mode selection and spectrum division.The main contents of this paper are as follows:1.Stochastic geometry based cellular network communication analysis.A multi-tier heterogeneous cellular network model supporting D2 D and Full-duplex is established by a Poisson Point Process with a single channel,and we analyze the performance of transmit devices in different mode.Moreover,we consider the distance based dynamic power control and interference analysis.Finally,we analyze the SINR in different communication modes and we derived closed expressions of coverage probability and average rate.2.We conduct mode selection and spectrum allocation according to the analysis results.Based on the last step,we establish a multiple channel network.Firstly,the user equipments can be divided into cellular mode(MBS-cellular mode and SBS-cellular mode),D2 D reuse mode,and D2 D dedicated mode.Secondly,we consider distance and bias based mode selection.Finally,we present the optimal spectrum partition in the multi-tier heterogeneous cellular network.In conclusion,we conduct the performance analysis of multi-tier heterogeneous cellular network supporting D2 D and Full-duplex,and analyze the performance improvement and spectrum efficiency.The simulation results show that the introduction of D2 D,Full duplex and Small Base Station in cellular network can enhance the network performance and improve the spectrum efficiency.
