Abstract: This application provides a communication method and a communication apparatus. In this method, a sensing receive device sends first information to a sensing transmit device in advance, to use the first information to indicate a padding requirement of the sensing receive device for a trigger frame. The padding requirement is for sensing. The sensing transmit device sends the trigger frame having a padding bit for sensing to the sensing receive device. The padding bit is determined based on the padding requirement indicated by the first information. Therefore, the trigger frame sent by the sensing transmit device satisfies the padding requirement of the sensing receive device for the trigger frame.

Abstract: This application relates to the field of wireless communication, and is applied to a wireless local area network that supports the 802.11 series standards such as the 802.11bf standard, and in particular, to a measurement setup identifier determining method and a related apparatus. The method includes: A requesting station requests an AP as a proxy of the requesting station to perform sensing measurement. The AP obtains parameters used by the AP and a sensing responder in a proxy sensing procedure, and identifies the parameters. The AP uses an identifier different from an existing identifier at the AP when identifying the parameters. The AP then sends the parameters and the identifier to the sensing responder.

Abstract: This application relates to signal processing methods and apparatuses. An example method includes generating a physical layer protocol data unit (PPDU) and sending the PPDU. The PPDU includes a first field, and the first field includes M sequences. The M sequences include a first sequence, a second sequence, a third sequence, and a fourth sequence. A partial sequence in the first sequence, a partial sequence in the second sequence, a partial sequence in the third sequence, and a partial sequence in the fourth sequence are determined based on Golay complementary sequences.

Abstract: A method includes: A first node sends a threshold and a first packet to a second node. Correspondingly, the second node receives the threshold and the first packet from the first node. Then, the second node determines first channel state information CSI based on the first packet. If a change amount of the first CSI relative to preset CSI exceeds the threshold, the second node sends a second packet to the first node. If the change amount of the first CSI relative to the preset CSI does not exceed the threshold, the second node does not need to send the second packet to the first node. The method is applied to a radio sensing process.
