Abstract: A communication method and apparatus are provided. The method includes: A first device receives first information, where the first information includes phase information of a second device on M resources, and the M resources are frequency resources. The first device receives a first signal from the second device on one or more of the M resources. The first device obtains measurement information, where the measurement information is determined based on the first signal and the first information. In embodiments of this application, after receiving signals on the one or more of the M resources, the first device may determine phase information between the received signals based on the first information, so that the phase information between the received signals may be considered when the measurement information is obtained. This reduces interference caused by a difference between phases of different signals, to improve accuracy of the obtained measurement information.

Abstract: A device wake-up method and a communication apparatus are provided. The method includes: A first device determines wake-up information, where the wake-up information is used for waking up a second device, or is used for not waking up a second device; determines a wake-up sequence based on the wake-up information; and sends the wake-up sequence to the second device on a wake-up signal receiving occasion of the second device. A frequency domain resource occupied for transmitting a low power wake-up symbol is adjacent to the edge of the transmission bandwidth of the first device in frequency domain, so that impact of transmitting the low power wake-up symbol on spectrum efficiency of a primary communication link can be reduced, thereby helping ensure compatibility between a link for transmitting the low power wake-up symbol and the primary communication link.
