Title:
LISTEN BEFORE TALK (LBT) FAILURE INDICATING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/197029
Kind Code:
A1
Abstract:
The present application provides a Listen Before Talk (LBT) failure indicating method and apparatus. The method comprises: when a first device determines that a continuous LBT failure occurs in a link with a second device, the first device sends an LBT failure report to a third device, wherein the LBT failure report is used for indicating the continuous LBT failure, and the third device is a parent node or host node or child node of the first device. By means of the method above, when the first device determines that a continuous LBT failure occurs between the first device and the second device, the continuous LBT failure can be indicated to the parent node or host node or child node of the first device. Because no LBT failure occurs in a link between the first device and the parent node or host node or child node of the first device, a network can be ensured to identify in time whether a continuous LBT failure occurs in the first device, thus processing can be performed in time, and the impact on the data transmission of the first device is reduced.
