Abstract

The invention relates to a direct link data transmission method and device, and a storage medium. The direct link data transmission method is applied to a first terminal and comprises the steps of acquiring non-continuous receiving DRX information transmitted from a second terminal; determining a direct link resource based on the DRX information, and transmitting direct link data to the second terminal based on the direct link resource. Through the method of the invention, data loss can be prevented.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a direct link data transmission method, device, and storage medium. Background technique [0002] In order to support direct communication between terminals, a direct link (Sidelink) communication mode is introduced. In the Sidelink communication mode, the communication interface between the sending terminal and the receiving terminal is PC-5. According to the corresponding relationship between the sending terminal and the receiving terminal, Sidelink supports three transmission methods, unicast, multicast and broadcast. The sending terminal sends Sidelink Control Information (Sidelink Control Information, SCI) on a Physical Sidelink Control Channel (Pysical Sidelink Control Channel, PSCCH) channel. Wherein, the SCI carries the resource location of the transmitted data, the source identifier, the target identifier, and the like. After receiving the SCI, th...
