Wireless network D2D resource allocation method and device, base station and medium

Abstract

The embodiment of the invention provides a wireless network D2D resource allocation method and device, a base station and a medium. The D2D terminal is selected for resource allocation by comprehensively considering the interference channel gain between the D2D terminal pair and the Eav and between the D2D terminal pair and the CUE, whether the D2D terminal pair is the terminal pair for resource allocation for the first time or not and other factors. The priority coefficient of each D2D terminal pair is calculated by acquiring resource allocation parameters of a plurality of D2D terminal pairs to be subjected to resource allocation, then three D2D terminal pairs with the highest priority are selected from the D2D terminal pairs to serve as candidate terminal pairs, the CUE secrecy rate of each candidate terminal pair is calculated, the terminal pair with the highest CUE secrecy rate is selected to serve as a target terminal pair, and the to-be-allocated resources are allocated to the target terminal pair. According to the scheme, the target terminal pair is selected by calculating the priority coefficient of the D2D terminal pair and the CUE secrecy rate, so that the channel resource utilization rate is effectively improved, the throughput is increased, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a wireless network device-to-device (Device to Device, D2D for short) resource allocation method, device, base station and medium. Background technique [0002] With the development of modern communication technology, network communication has a shortage of resources. The emergence of D2D communication improves the performance of traditional network communication and improves the utilization rate of resources. The D2D transmission carrier is a telecom operator, which does not rely on the network transmission base station. In social applications, two users can facilitate resource sharing and information exchange. Merchants can promote and promote related products through D2D communication, and D2D communication technology can be combined with things. The combination of networking realizes the interconnected wireless communication network in the true sense, and...
