Periodic resource selection method, side link transmission method and terminal

Abstract

Provided in an embodiment of the present invention are a periodic resource selection method, a side link transmission method and a terminal. The periodic resource selection method comprises: performing periodic resource reservation or resource detection according to periodic resource reservation rule information; the periodic resource reservation rule information comprising at least one of the following: a resource reservation period, and the resource reservation period is set according to a TB transmission interval; the target number of resources reserved in one resource reservation period being M. In the embodiment of the invention, the terminal can keep consistent information understanding according to the periodic resource reservation rule information and perform periodic resource reservation or resource detection, so that other terminals can accurately exclude the periodically reserved resources when selecting the resources, the problem of resource collision is avoided, and the reliability of data transmission of the terminal can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of wireless communication technologies, and in particular, to a periodic resource selection method, a sidelink transmission method, and a terminal. Background technique [0002] The Long Term Evolution (LTE) system supports sidelinks (sidelinks, or translated as secondary links, side links, side links, etc.) UEs, hereinafter referred to as terminals) do not perform direct data transmission through network devices. [0003] The design of LTE sidelink is suitable for specific public safety affairs (such as emergency communication in fire places or disaster places such as earthquakes), or vehicle to everything (V2X) communication, etc. Vehicle networking communication includes various services, such as basic safety communication, advanced (automatic) driving, platooning, sensor expansion and so on. Since LTE sidelink only supports broadcast communication, it is mainly used for basic security commu...

Problems solved by technology

[0005] The embodiment of the present invention provides a periodic resource selection method, a sidelink transmission method and a terminal, which are used to solve the problem that the terminal in the sidelink system does not have a unified understanding of the rules for periodically reserving resources, which makes resource exclusion inaccurate when selecting resources , leading to the problem of resource collision
