Abstract

The invention provides a terminal D2D communication method and a terminal D2D communication system. The terminal D2D communication method includes the steps that each base station distributes a plurality of time-frequency resource combinations used for terminal D2D communication for a D2D terminal which is served by the base station, so that a resource pool is formed; different base stations distribute the same resource pool for the D2D terminals which are served by different base stations for D2D transmission so as to ensure that the D2D terminals which are served by different base stations can be in D2D communication. According to the technical scheme, the problem that adjacent cell edge terminals cannot be in communication due to different communication resources can be solved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular, to a terminal direct connection communication method and a terminal direct connection communication system. Background technique [0002] Terminal direct communication (Device to Device, D2D) means that the terminal does not forward through the network, but the terminal directly communicates. Since base station forwarding is not required, the air interface resources of the mobile network can be greatly saved, and the network capacity can be further improved. At the same time, the robustness of D2D is also better than that of existing mobile communication networks, especially after disasters or areas without mobile network coverage. [0003] In the D2D communication process, 3GPP defines two communication resource scheduling modes: [0004] Mode 1: The network (base station) directly schedules the communication transmission resources of the D2D UE. [0005] Mode...
