Problems solved by technology

However, NR V2X communication supports a more flexible reservation period. If the above-mentioned method of excluding reserved resources in LTE V2X communication is continued, it will result in too few or no resources in the resource selection window, which will lead to NR V2X communication fail

Embodiment Construction

[0071] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0072] In V2X communication, from the perspective of whether network devices are required to perform resource scheduling, resource allocation methods are divided into scheduling resource allocation methods and perception-based resource selection methods. Among them, the scheduling resource allocation method includes mode3 in LTE V2X communication and mode 1 i...

Abstract

The embodiment of the invention provides a resource selection method for auxiliary link communication and a communication device. First electronic equipment determines a first auxiliary link resource, a first reservation period, at least one second auxiliary link resource in each first reservation period and a second reservation period of each second auxiliary link resource. Afterwards, the first electronic equipment sends auxiliary link resource auxiliary information on the first auxiliary link resource in the current first reservation period, and the auxiliary link resource auxiliary information is used for indicating which auxiliary link resources are reserved or which auxiliary link resources are not reserved. After receiving the auxiliary information of each auxiliary link, the second electronic equipment excludes auxiliary link resources periodically reserved by other equipment from the resource selection window, and selects auxiliary link communication resources from the residual auxiliary link resources. As the at least one second auxiliary link resource is the auxiliary link resource determined according to the half-duplex communication, the purpose of reducing the half-duplex influence can be achieved by sending the auxiliary link auxiliary information.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a resource selection method and a communication device for auxiliary link communication. Background technique [0002] Vehicle to everything (Vehicle to X, V2X) communication is a key technical direction of the 16th (Release 16, R16) version of the protocol. NR V2X, as an enhancement of Long Term Evolution (LTE) V2X, is the key to enabling the Internet of Vehicles Key technical means. [0003] In V2X communication, sidelink communication is performed between V2X devices through a sidelink. For V2X communication, there are two resource allocation methods. The first method is scheduled resource allocation. In this method, the base station configures resources for auxiliary link communication for V2X devices. This method mainly applies Mode (mode3) in LTE V2X communication and mode 1 in NR V2X communication; the second method is a resource...
