基站控制下的d2d频谱分配方法

Method of D2D spectrum allocation controlled by base station

Abstract

基站控制下的D2D频谱分配方法,属于无线通信技术领域。本发明在确定蜂窝用户对D2D用户的干扰条件下,由基站主动在对D2D用户的干扰低于干扰门限值的蜂窝用户中选择一个具有发射功率余量、且未被其它D2D用户共享的蜂窝用户的频谱分配给D2D用户共享。本发明能够有效减轻D2D用户共用蜂窝用户带来的相互干扰,保证两者的正常通信,进而提高了频谱效率,相比D2D用户自主决定频谱分配的方法,本发明通过基站主动管理D2D的通信,能更有效的保证蜂窝链路的通信质量,运营商和设备商都更易于接受。
The invention relates to a method of D2D spectrum allocation controlled by a base station and belongs to the technical field of wireless communications. According to the method, when the situation that honeycomb users interfere with D2D users is determined, the base station actively selects a spectrum of the honeycomb users from those of the honeycomb users with the interference in the D2D users lower than an interference threshold value to allocate the spectrum to the D2D users to be shared, wherein the spectrum of the honeycomb users has a transmitting power margin and has not been shared by other D2D users. The method can relieve the mutual interference brought by the situation that the D2D users share spectra with the honeycomb users, ensure normal communication between the D2D users and the honeycomb users and thus promote spectrum efficiency. Compared with the method of spectrum allocation autonomously determined by the D2D users, the method of D2D spectrum allocation controlled by the base station can ensure the communication quality of honeycomb links more effectively and easier to accept by both an operator and an equipment merchant because the D2D communication is managed actively by the base station.
