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.
Claims20
A radar measurement method, wherein the method comprises:
- generating, by an access point (AP), a first frame that comprises radar measurement information;
- sending, by the AP, the first frame to M stations (STAs) to obtain information corresponding to an object, wherein M is a positive integer, and wherein the first frame instructs at least one of:
- the M STAs to get ready for a radar measurement comprising receiving a radar signal initiated by at least one of the M STAs;
- or
- each STA in the M STAs to perform a radar measurement comprising transmitting the radar signal;
- sending, by the AP, a first poll frame to a target STA in the M STAs, wherein the first poll frame is to trigger the target STA to perform radar measurement;
- sending, by the AP, a second poll frame to the target STA, wherein the second poll frame is to trigger the target STA to feed back radar measurement data;
- and
- receiving, by the AP, a sixth frame sent by the target STA that comprises the radar measurement data.
A radar measurement method, wherein the method comprises:
- receiving, by a station (STA), a first frame sent by an access point (AP), wherein the first frame comprises radar measurement information corresponding to an object;
- determining, by the STA, the radar measurement information based on the first frame, wherein the first frame instructs the STA to at least one of:
- the STA to get ready for a radar measurement comprising receiving a radar signal initiated by at least one STA, or
- the STA to perform a radar measurement comprising transmitting the radar signal;
- receiving, by the STA, a first poll frame sent by the AP, wherein the first poll frame is to trigger the STA to perform the radar measurement;
- performing, by the STA, the radar measurement comprising transmitting the radar signal based on the radar measurement information;
- receiving, by the STA, a second poll frame sent by the AP, wherein the second poll frame is to trigger the STA to feed back radar measurement data;
- and
- sending, by the STA, a sixth frame to the AP, wherein the sixth frame comprises the radar measurement data.
A radar measurement apparatus comprising:
- a memory storing executable instructions;
- and
- a processor that, when executing the executable instructions, is configured to:
- generate a first frame that comprises radar measurement information;
- send the first frame to M stations (STAs) to obtain information corresponding to an object, wherein M is a positive integer, and wherein the first frame instructs at least one of:
- the M STAs to get ready for a radar measurement comprising receiving a radar signal initiated by at least one of the M STAs, or each STA in the M STAs to perform a radar measurement comprising transmitting the radar signal;
- send a first poll frame to a target STA in the M STAs, wherein the first poll frame is to trigger the target STA to perform radar measurement;
- send a second poll frame to the target STA, wherein the second poll frame is to trigger the target STA to feed back radar measurement data;
- and
- receive a sixth frame sent by the target STA, that comprises the radar measurement data.
A radar measurement apparatus comprising:
- a memory storing executable instructions;
- a processor that, when executing the executable instructions, is configured to:
- receive a first frame sent by an access point (AP), wherein the first frame comprises radar measurement information corresponding to an object;
- determine the radar measurement information based on the first frame, wherein the first frame instructs a station (STA) to at least one of:
- the STA to get ready for a radar measurement comprising receiving a radar signal initiated by at least one STA, or
- the STA to perform a radar measurement comprising transmitting the radar signal;
- receive a first poll frame sent by the AP, wherein the first poll frame is to trigger the STA to perform the radar measurement;
- perform the radar measurement comprising transmitting the radar signal based on the radar measurement information;
- receive a second poll frame sent by the AP, wherein the second poll frame is to trigger the STA to feed back radar measurement data;
- and
- send a sixth frame to the AP, wherein the sixth frame comprises the radar measurement data.
