Abstract

The embodiment of the invention relates to the technical field of communication, in particular to a D2D communication method, a terminal and a network device. In the application, a first terminal receiving a first frame stores sending sector information in the first frame according to indication information, and generates and sends a second frame including preferred sending sector information of each second terminal to the first terminal to a network device; The network device receives at least one second frame, Information integration, and generating a third frame including preferred transmission sector information of a fourth terminal to terminals other than the fourth terminal, and respectively transmitting the third frame to the fourth terminal, Therefore, the fourth terminal knows thepreferred sending sector information of the fourth terminal to the terminals except the fourth terminal, so that when the fourth terminal performs D2D communication with the terminals except the fourth terminal, the process of sending sector training can be saved, and the communication process and resources are 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...
