Title:
FEEDBACK INFORMATION TRANSMISSION METHOD AND APPARATUS, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/044938
Kind Code:
A1
Abstract:
An information transmission method and apparatus, and a storage medium, which may be applied to systems such as the Internet of Vehicles, V2X, and V2V. The method comprises: determining time-frequency domain resources of M physical sidelink feedback channels (PSFCH) corresponding to a physical sidelink shared channel (PSSCH), M being an integer greater than 1; determining a PSFCH for sending hybrid automatic repeat request (HARQ) information corresponding to the PSSCH; and sending the HARQ information on the determined PSFCH. Therefore, after a first terminal fails to perform LBT on one PSFCH time-frequency domain resource leading to a failure in sending HARQ information, the first terminal may perform LBT on a PSFCH time-frequency domain resource among the M PSFCH time-frequency domain resources other than the failed PSFCH time-frequency domain resource, and after LBT has succeeded, sends HARQ information, so as to improve the stability of information transmission and improve communication efficiency.
