Abstract

The invention discloses a D2D communication method in a cellular network, which includes dividing a cell into a dedicated resource area and a shared resource area; according to the interference status information and interfering D2D terminal information reported by D2D terminals in the cell, the D2D communication in the cell is divided into Perform clustering; the two terminals in D2D communication share the D2D resource allocation control information issued by the base station and can decode the control information at the same time. The D2D receiving end directly reports ACK / NACK and interference status indication to the base station. The D2D communication method in the cellular network of the present invention can coordinate the interference between the cellular communication link and the D2D communication link and improve network performance while taking into account the service quality of cellular users and D2D users.

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...
