| Abstract: | With the advent of the Internet of Things and the era of big data， spectrum resources have become increasingly scarce. D2D communication technology has been introduced into the cellular network for alleviating the situation of spectrum resources and improving the utilization of spectrum resources. The service performance of the cellular communication network has been improved through reasonable resource allocation and power control， combining with technologies such as NONA， EH and Relay， it reduces the delay of communication and improves the utilization of spectrum resources. Compared with the traditional cellular communication network， D2D communication technology joined into the cellular network can expand the coverage of the cellular network， improve the throughput of the edge users， and the throughput for users as a whole， it will has a broad application prospect. |
