Abstract: An information transmission method and apparatus are provided. The method includes: A first communication apparatus determines feature information of a target channel and first common delay information, and determines scrambling information based on the feature information of the target channel. The first communication apparatus processes the first common delay information based on the scrambling information, to obtain second common delay information. The first communication apparatus sends the second common delay information through the target channel. A second communication apparatus receives the second common delay information through the target channel, and determines the feature information of the target channel. The second communication apparatus determines descrambling information based on information of the target channel, and further processes the second common delay information based on the descrambling information to obtain the first common delay information. In this solution, both the first communication apparatus and the second communication apparatus respectively determine corresponding scrambling information and descrambling information based on feature information of a transmission channel of common delay information, to ensure that the second communication apparatus obtains correct first common delay information.

Abstract: A communication method includes a first communication apparatus that receives a measurement signal from a second communication apparatus. The first communication apparatus sends measurement evaluation information to the second communication apparatus. The measurement evaluation information indicates reliability of a measurement result due to a first cause or that the measurement result is unavailable due to the first cause. The measurement result is obtained based on the measurement signal. In this way, the first communication apparatus sends the measurement evaluation information to the second communication apparatus, where the measurement evaluation information indicates the reliability of the measurement result due to the first cause or indicates that the measurement result is unavailable due to the first cause.

Abstract: A method includes a first device that sends a spectrum sensing request frame to a second device, where the spectrum sensing request frame requests the second device to perform spectrum sensing. The second device sends a request acknowledgment frame which, is used to acknowledge that the spectrum sensing request frame is received. The second device performs spectrum sensing based on the at least one spectrum sensing parameter, to obtain a spectrum sensing result. The second device sends a spectrum sensing feedback frame to the first device, where the spectrum sensing feedback frame is used to feed back the spectrum sensing result. The first device sends the spectrum sensing request frame, so that the second device can perform spectrum sensing based on information carried in the spectrum sensing request frame, and the first device can obtain the accurate spectrum sensing result of the second device.
