Abstract

The invention discloses a D2D communication method in a cellular network. The method includes the steps that a cell is divided into a dedicated resource area and a shared resource area; according to interference state information and interference D2D terminal information which are reported by a D2D terminal in the cell, clustering is conducted on D2D communication pairs in the cell; two terminals of D2D communication share D2D resource distribution control information issued by a base station, the control information can be decoded at the same time, and a D2D receiving end directly reports ACK / NACK and interference state instructions to the base station. According to the D2D communication method in the cellular network, consideration to the service quality of cellular users and the service quality of D2D users can be given, meanwhile, interference between a cellular communication link and a D2D communication link can be coordinated, and the network performance can be improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular, to a device-to-device (Device-to-Device, D2D) communication method in a cellular network. Background technique [0002] Cellular network (Cellular network), also known as mobile network, is a mobile communication hardware architecture, which divides the service area of ​​mobile phones into regular hexagonal sub-areas, and each cell has a base station (Base Station, BS) , Forming a structure that resembles a "honeycomb", so this mobile communication method is called a cellular mobile communication method. Cellular networks can be divided into analog cellular networks and digital cellular networks, which are mainly different from the way of transmitting information. Common cellular network types are: GSM network (called pcs-1900 in some countries), CDMA network, 3G network, 4G network, etc. [0003] In the future cellular network, diversified and emerging dat...
