Abstract
A method includes: determining a start time point of a resource selection window based on a first time point for triggering resource selection, and selecting a transmission resource in the resource selection window. A time interval between the start time point of the resource selection window and the first time point is not less than duration required by a terminal device to perform first-type listen-before-talk (LBT).
Claims17
A method, comprising:
- determining a start time point of a resource selection window, wherein a time interval between the start time point of the resource selection window and a first time point is not less than first duration, the first time point is a time point for triggering resource selection, and the first duration is duration required for a terminal device to perform first-type listen-before-talk (LBT);
- and
- selecting a transmission resource in the resource selection window,
- wherein a quantity T1 of slots corresponding to the time interval between the start time point of the resource selection window and the first time point meets:
