Embodiment Construction

[0049] In order to facilitate those skilled in the art to understand the technical content of the present invention, the content of the present invention will be further explained below in conjunction with the accompanying drawings.

[0050] Such as figure 1 Shown is the network scenario adopted by the embodiment of the present invention, and the simulated real uplink communication scenario is specifically: N cellular users and D pairs of D2D user pairs are randomly distributed in the cell, so that represents the set of cellular users, Represents a collection of D2D user pairs; the distance between D2D user pairs is randomly distributed within a certain range, the certain range is [550]m, N users are randomly distributed, and there are N channels in the system, and each user uses one Channel, there are no idle channel resources in the system, thus forming an uplink communication network scenario. In this scenario, there are two types of intra-cell interference, interferenc...

Abstract

The invention discloses a joint wireless resource allocation and power control method based on D2D communication, applied to the technical field of wireless communication. A wireless resource allocation and power control algorithm based on GP (Geometric Programming) is adopted, the QoS (Quality of Service) of D2D (Device-To- Device) users and cellular users are classified in related decision making factors, the power limits of the D2D user pairs and the cellular users are comprehensively considered, and a total rate of all D2D user pairs is calculated; and the high-speed and lower-power reliable transmission in an uplink D2D communication network can be effectively satisfied.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a joint resource allocation and power control technology based on D2D communication. Background technique [0002] With the development of mobile communication technology, the number of wireless communication users is increasing explosively, users' requirements for data transmission rate are increasing day by day, and the problem of shortage of spectrum resources is becoming more and more serious. D2D (Device-to-Device) communication is a new technology that allows adjacent terminals to communicate directly using cellular resources under the control of a base station. Different from traditional communication methods, D2D user pairs pass through the D2D direct link, and their data transmission no longer passes through the relay of the base station. D2D communication technology and relay technology can effectively improve the spectrum utilization rate of...
