Embodiment Construction

[0031] As mentioned in the background, LTE V2X completely separates synchronization resources and resources (resource pool) for sending PSCCH / PSSCH through time division multiplexing (Time Division Multiplexing, TDM). If NR V2X supports multiple cycles, it will cause a lot of waste of resources to divide the resource pool directly by using the complete TDM method of LTE V2X, especially considering that there may be multiple SSBs in one cycle for repetition or beam scanning (beam scanning). -sweeping).

[0032] In the technical solution of the present invention, by monitoring the synchronization signal block at the receiving resource position of the direct link synchronization signal block, it can be determined whether the receiving user equipment has sent the synchronization signal block, so that it can be determined that the receiving user equipment has not sent the direct link synchronization signal block The receiving resource is the target idle resource, so that on the bas...

Abstract

Provided are a data transmission method and device based on synchronization resources, a storage medium, and user equipment. The data transmission method based on synchronization resources comprising:monitoring a direct link synchronization signal block at a reception resource position of the direct link synchronization signal block in at least one monitoring period; in each monitoring period, atleast determining that a receiving resource, which does not send the direct link synchronization signal block, of receiving user equipment is a target idle resource; and sending V2X data by using thetarget idle resource in each monitoring period. According to the technical scheme, the resource utilization rate in the V2X service scene can be improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a synchronization resource-based data transmission method and device, a storage medium, and user equipment. Background technique [0002] For the user equipment (User Equipment, UE) in the Long Term Evolution (LTE) Internet of Vehicles (Vehicle-to-Everything, V2X), the transmission of synchronization information adopts a fixed period of 160 milliseconds (ms) (that is, 160 subframes ). The resource occupied by the synchronization information is determined by the pre-configuration of the UE. In the form of the parameter syncOffsetIndicators in the pre-configuration information, 2 or 3 subframes are used to transmit synchronization information. The UE can determine which resource to use for transmission according to its own synchronization source information. For example, if UE-1 is currently directly synchronized to the base station, the base station will in...
