Embodiment Construction

[0026] As mentioned in the background, in the actual process, since the generation of V2X data is not completely periodic, sometimes the semi-static direct link transmission resources pre-configured by the base station for the Tx UE are wasteful; if such The situation often occurs and will significantly reduce the spectral efficiency of the entire system.

[0027] In the technical solution of the present invention, for the direct link transmission resources configured by the base station for transmitting V2X data, the user equipment can determine the direct link transmission resources that can be used for uplink transmission by receiving the uplink indication information; thus, the user equipment can When no V2X data is generated and the base station has allocated direct link transmission resources for the V2X data, the user equipment can use the direct link transmission resources to transmit uplink data, thereby avoiding waste of direct link transmission resources and improvin...

Abstract

Provided are an uplink transmission method and device based on direct link resources, and a storage medium. The uplink transmission method based on direct link resources comprises: receiving pre-configured uplink indication information, the uplink indication information comprising an identifier of a direct link transmission resource that can be used for uplink transmission; and when the direct link transmission resource corresponding to the identifier is not used to transmit V2X data, transmitting uplink data by using the direct link transmission resource. According to the technical scheme, the spectral efficiency of data transmission can be improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to an uplink transmission method and device based on direct link resources, and a storage medium. Background technique [0002] In the communication standard protocol version 12 (Release 12), the Long Term Evolution (Long Term Evolution, LTE) system introduces direct communication (Direct Communication). Multiple user equipments (User Equipment, UEs) can communicate directly through the PC5 interface. The PC5 interface is a direct interface between UEs. There are two modes of resource allocation in the prior art, one is scheduled resource allocation, which is configured by the base station through dedicated signaling; the other is automatic resource selection (autonomous resource selection), the base station A resource pool for direct communication may be provided to the UE through system messages or radio resource control (Radio Resource Control, RRC) signali...
