Information sending method based on D2D technology, device and equipment

Abstract

The invention provides an information sending method based on a D2D technology, a device thereof and equipment. The method comprises the following steps:obtaining the value of the signal-to-noise ratio of each channel to be selected by a D2D user terminal to form a channel sequence; and according to the sequence of the channels to be selected in the channel sequence, repeating the following steps until an information sending channel is determined: if the signal-to-noise ratio of the current channel to be selected is determined to be greater than or equal to a preset signal-to-noise ratio threshold and the current channel to be selected is occupied by other terminals, acquiring first time and second time of the current D2D terminal, acquiring third time and fourth time of other terminals occupying the current to-be-selected channel; and determining an information sending channel according to the time information, and transmitting information based on the information sending channel. According to the method, the actual information transmission conditions of other terminals occupying the current to-be-selected channel and the waiting time delay tolerance of the D2D terminal service are comprehensively considered, and the personalized requirements of the service waiting time of different terminal services are met.

Description

Technical field [0001] The present application relates to communication techniques, and more particularly to a D2D-based information transmitting method, apparatus, and equipment. Background technique [0002] D2D (Device to Device) communication technology is a new type of communication technology that has been applied to the communications. When the D2D terminal is transmitted, it is necessary to determine the channel, based on the channel transmission information. [0003] In the prior art, when the D2D terminal is transmitted, it is necessary to queue in the order of the terminal service established in the terminal service, and the channel resource transmission information is allocated according to the order. [0004] However, prior art, D2D terminals are allocated in selection channels in selection channels, and the allocation mode is too single, which will result in a time-to-endurance terminal service that cannot be transmitted promptly, and cannot meet different terminal ...

AI Technical Summary

Problems solved by technology

[0004] However, in the existing technology, when D2D terminals select channels, they only allocate channel resources in order of time. The allocation method is too single, which will cause terminal services with low delay tolerance to be unable to transmit information in a timely manner, and cannot satisfy different terminal services. individual needs
