Abstract

The embodiments of the present application relate to the field of communication technologies, and in particular, to a D2D communication method, a terminal, and a network device. In this application, the first terminal that receives the first frame saves the transmission sector information in the first frame according to the indication information, and generates and sends to the network device the preferred transmission sector information of each second terminal to the first terminal. The second frame of information; the network device performs information integration according to at least one received second frame, generates a third frame containing the preferred transmission sector information of the fourth terminal to terminals other than the fourth terminal and respectively sent to the fourth terminal, so that the fourth terminal knows the preferred transmission sector information of the fourth terminal to terminals other than the fourth terminal, so that when the fourth terminal communicates with terminals other than the fourth terminal During D2D communication, the process of sending sector training can be saved, and the communication process and resources can be saved.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a D2D communication method, a terminal, and a network device. Background technique [0002] Device-to-Device (D2D) communication is a new technology that allows terminals to communicate directly by reusing cell resources under the control of the system. It can increase the spectrum efficiency of the cellular communication system and reduce the terminal transmit power. To a certain extent, it solves the problem of lack of spectrum resources in wireless communication systems. [0003] In the existing IEEE802.11ad standard, the D2D communication process is stipulated as follows: D2D communication occurs in the DTI phase, and the AP polls each STA in turn, and the STA that needs D2D communication replies to the AP and applies for D2D communication. The STA that needs D2D communication carries the MAC address of the target STA of D2D communic...
