Title:
COUNTING METHOD AND APPARATUS FOR NUMBER OF LBT FAILURES
Document Type and Number:
WIPO Patent Application WO/2024/092622
Kind Code:
A1
Abstract:
Provided in the present disclosure are a counting method and apparatus for the number of LBT failures, which method and apparatus can be applied to mobile communication technology. The method comprises: determining the number of LBT failures that consecutively occur in a physical sidelink feedback channel (PSFCH) associated with a hybrid automatic repeat request (HARQ) enabled physical sidelink shared channel (PSSCH) (201); and counting the number of LBT failures in the PSFCH according to the number of LBT failures that consecutively occur in the PSFCH, which is associated with the HARQ enabled PSSCH (202). The method can prevent the frequent triggering of consecutive sidelink LBT failures, thereby improving the quality of link communication.
