摘要： The disclosure provides a method for channel detection, devices, and a storage medium, which can be applied to a terminal device on sidelink (SL). The method includes the following. Monitor a channel before a time-unit boundary and/or after the time-unit boundary, and determine, according to a channel monitoring result, whether to perform blind detection in a time unit next to the time-unit boundary. When it is determined or it is determined with a high probability there is no SL transmission in the next time unit according to the channel monitoring result, the terminal device does not need to perform blind detection in the next time unit, which can reduce the number of times of blind detections performed by the terminal device, thereby reducing power consumption of the terminal device.
