Title: CHANNEL MEASUREMENT METHOD AND APPARATUS, AND TERMINAL
Abstract:
The present application provides a channel measurement method. The method comprises: a first wireless device obtains channel reservation information of a second wireless device on a first channel; the first wireless device determines a first time range according to the channel reservation information; the first wireless device determines, according to the first time range, a second time range for performing channel measurement by the first wireless device; and the first wireless device performs channel measurement in the second time range. When a wireless device performs channel measurement, the wireless device can obtain when the second device releases the first channel. If a second channel satisfying a switchover is detected by means of measurement in a channel reservation time range, the first wireless device switches to a second channel and performs idle channel evaluation. If the first wireless device does not obtain, by means of measurement, a second channel satisfying the switchover condition and the second wireless device is to release the first channel, the first wireless device performs idle channel evaluation on the first channel and preempts the first channel, thereby improving the data transmission efficiency.
