Description

CROSS-REFERENCE TO RELATED APPLICATIONS The present application is the U.S. National Stage of International Application No. PCT/CN2021/080311 filed on Mar. 11, 2021, the entire contents of which are incorporated herein by reference for all purposes. TECHNICAL FIELD The present disclosure relates to the field of communication technology, and in particular to a communication method, a communication device and a storage medium. BACKGROUND Since the Long Term Evolution (LTE), the Third Generation Partnership (3GPP) has been developing the Sidelink standard as a standard for direct end-to-end communication. In July 2020, the first Sidelink standard of New Radio (NR) was completed in Rel-16, where the NR Sidelink solution is focused on Vehicle to Everything (V2X) and public safety. For V2X and public safety, due to time constraints, Release 16 does not fully support service requirements and operation schemes, and the Service and System Aspects (SA) is making some enhancements to the NR Sidelink in Release 17, such as architectural enhancements and system enhancements for 3GPP supporting advanced V2X services. In addition, other business use cases related to the NR Sidelink, such as interactive services for network control, enhanced energy efficiency relays, wide coverage, audiovisual service production, are being investigated in the SA working group. Therefore, in the 86th plenary session of 3GPP, the enhancement of the NR Sidelink was included as a work item in the project establishment of Release 17, with the aim of enhancing the reliability of Sidelink transmissions and reducing the latency thereof. In the enhancement of NR Sidelink, a user device A for sidelink communication can send a set of auxiliary resources to a user device B with a resource selection mode of Mode 2, which is taken into account by the user device B in resource selection for data transmission thereof. However, in the Mode 2 resource selection mechanism in the related art, there is a problem that consecutive collisions of resources selected by a plurality of terminals in a plurality of transmission periods lead to a degradation of communication reliability.
