Abstract: A radar measurement method and an apparatus are disclosed, which relate to the field of communications technologies, and are used to support radar measurement in a wireless local area network (WLAN). The method includes: An access point (AP) generates a first frame, where the first frame includes radar measurement information. Then the AP sends the first frame to M stations (STAs), to configure the way the M STAs perform radar measurement. This application is applicable to a radar measurement procedure.

Abstract: Embodiments of this application relate to the communications field, and in particular, to an information indication method and apparatus in the communications field. The embodiments of this application include: generating a PPDU including radar indication information, where the radar indication information is used to indicate that the PPDU is a PPDU used for radar testing, and transmitting the PPDU. According to the method provided in the embodiments of this application, the transmit end explicitly indicates that the PPDU is a PPDU used for radar testing rather than a PPDU used for communication between communications devices. When a receive end receives the PPDU, the receive end no longer monitors a channel, thereby reducing power consumption of the receive end.
