Document Type and Number:
WIPO Patent Application WO/2020/191631
Kind Code:
A1
Abstract:
The present invention relates to a slot format indication method and apparatus. The method comprises: after listen-before-talk (LBT) is performed on an activated bandwidth part (BWP) on a target serving cell corresponding to a terminal, determining a target LBT BW unit, a corresponding channel of which is idle, from among various LBT channel detection bandwidth (BW) units comprised in the activated BWP; and sending downlink control information (DCI) to the terminal, wherein the DCI comprises a slot format indication (SFI) of the target LBT BW unit. According to the technical solution, by means of indicating an SFI on the basis of an LBT channel detection bandwidth unit, and notifying a terminal that channels corresponding to which of the LBT BW units are idle, the terminal obtains a specific SFI and an applicable LBT BW unit, the specific indication of a slot format is realized, and the reliability of a system can be improved.
