description Embodiments of the preset application provide a large-scale D2D communication method based on HARQ assisted NOMA. This method firstly analyzes the influence of superimposed interference on the outage probability in the large-scale D2D network using the stochastic 5 geometry, then deriving the specific expression of the spectrum efficiency according to the relationship between the outage probability and spectrum efficiency, and finally constructing an optimization problem of the resource allocation based on these theoretical analysis results: the spectrum efficiency (throughput or spatial spectrum utilization) may be maximized and the reliability of the communication may be ensured via reasonably configuring information 10 transmission rate of different D2D users or even configuring the distribution density of D2D devices occupying the same time-frequency resource. Simulation and numerical results show that compared with the no-cooperative application scheme, the proposed cooperative application scheme decreases the outage probability by up to 23%. Further, the optimized LTAT of proposed scheme outperforms that of the OMA scheme by 17%. Interference user z $SI+ 4 7S2 ...
