A WLAN terminal may have one or more roles in a sensing session. For example, a sensing initiator device can be only a sensing initiator device, or a sensing signal sending device, a sensing signal receiving device, or a sensing signal sending device at the same time. and sensory signal receiving equipment.

For example, as shown in Figure 2a, STA1 may be a sensing initiator (Sensing Initiator), may also be a sensing signal receiving device (Sensing Receiver), or may be a sensing processing device (Sensing processor); STA2 may be a sensing signal sending device ( Sensing Transmitter).

For another example, as shown in Figure 2b, STA1 can be a sensing initiator (Sensing Initiator), or a sensing signal transmitting device (Sensing Transmitter); STA2 can be a sensing signal receiving device (Sensing Receiver), or a sensing processing device (Sensing processor).

For another example, as shown in Figure 2c, STA1 may be a sensing initiator or a sensing processor; STA2 may be a sensing signal receiving device (Sensing Receiver); STA3 may be a sensing signal sending device (Sensing Transmitter).

For another example, as shown in Figure 2d, STA1 can be a sensing initiator (Sensing Initiator), a sensing signal receiving device (Sensing Receiver), or a sensing processing device (Sensing processor); STA2 can be a sensing signal sending device (Sensing Transmitter); STA3 may be a sensing signal sending device (Sensing Transmitter).

For example, STA1, STA2, and STA3 in Figure 2a to Figure 2j only represent the roles of STAs, and are not used to limit the number of STAs in Figure 2a to Figure 2j and subsequent steps such as sensing sessions and measurements, for example, STA1, STA2, The role represented by STA3 can be implemented as one or more STAs.

In some embodiments, there may be multiple sensing types (Sensing Type). For example, the sensing type based on channel state information (Channel State Information, CSI), that is, CSI-based Sensing, the sensing type obtains the sensing measurement result by processing the CSI of the received sensing measurement signal. Another example is the sensing type based on the reflection signal, that is, Radar-based Sensing.

The data volume of sensing measurement results is usually relatively large. For example, the Channel State Information (CSI) data of a measurement may reach 4K to 40K bits. In order to reduce the network load caused by reporting sensing measurement results, the measurement threshold can be set. When this When the variation between the second sensing measurement result and the previous sensing measurement result is less than the measurement threshold, the sensing signal receiving device reports the sensing measurement result, otherwise, it does not report the sensing measurement result.

2. Overall process of WLAN awareness session

Referring to Figure 3, the WLAN sensing session includes one or more of the following stages: session setup (Session Setup); sensing measurement setting establishment (Measurement Setup); sensing measurement (Measurement); sensing reporting (Reporting); sensing measurement setting end (Measurement Setup) Termination); session end (Session Termination). A WLAN terminal may have one or more roles in a perception session. For example, a perception session initiation device can be only a perception session initiation device, or a perception signal sending device, a perception signal receiving device, or a perception signal at the same time. Sending device and sensing signal receiving device.

Session establishment phase: establish a perception session, exchange the perception capabilities of both parties and/or determine the operation parameters related to the perception measurement, or the terminal declares its own role and operation parameters (for example, through beacon frames or other special frames).

Sensing measurement setting establishment phase: determine the sensing session participating devices and their roles (including sensing signal sending device and sensing signal receiving device), determine the operating parameters related to sensing measurement, and optionally exchange the parameters between terminals.

Session Termination Phase: Terminates all measurement setups, stops measurements, and terminates the sensing session.

3. Negotiation of WLAN sensing measurement setting parameters

When the perception measurement setting is established, the terminals may need to negotiate the perception roles and operation parameters one by one, or the terminals declare their own roles and operation parameters (for example, through beacon frames or other special frames). For example, referring to FIG. 4, SENS STA1 may be a sensing initiator and sending device (Sensing Initiator and Transmitter). SENS STA2 can be Sensing Responder and Receiver. SENS STA3 can be Sensing Responder and Transmitter. The sensing initiating device SENS STA1 sends a sensing request (SENS Request) to SENS STA2, and SENS STA2 sends a sensing response (SENS Response). The sensing initiating device SENS STA1 sends a sensing request (SENS Request) to SENS STA3, and SENS STA3 sends a sensing response (SENS Response).

4. Measurement settings and measurement examples

The perception session initiating device can set multiple sets of measurement parameters through the measurement setup (Measurement Setup) process. A set of measurement parameters (identified by the Measurement Setup ID, which can be equivalent to the Burst Group), can be applied to multiple measurements (each measurement is identified by the Measurement Instance ID) To identify, can be equivalent to the burst signal (Burst)).

In some embodiments, the sensing session initiating device can set multiple sets of measurement parameters through a measurement setup procedure (Measurement Setup procedure). A measurement setup (Measurement Setup, or measurement configuration, Measurement Configuration) generally includes a set of measurement parameters, which It can be identified by the Measurement Setup ID. A measurement setting can be applied to multiple measurements, and a measurement (which can be equivalent to a burst signal (Burst)) can be considered as a measurement instance (Measurement Instance), and a measurement instance can be identified by a measurement instance ID (Measurement Instance ID).

For example, referring to FIG. 5, the association identifier (Association Identifier, AID) of AP=0, the AID of STA1=1, the AID of STA2=2, and the unassociation identifier (Unassociation Identifier, UID) of STA3=3. Wherein, the AID is used to identify the terminal associated with the access point. The AP can establish measurement setups with STA1, STA2, and STA 3 at different time points, and the measurement setup ID (Measurement Setup ID)=1. AP can send perception measurement polling frame, perception announcement frame and perception measurement frame to STA1, STA2, STA 3 at the same time, measurement setting identification=1 and measurement instance identification=1. The AP can simultaneously send the perception measurement polling frame, the perception announcement frame and the perception measurement frame to STA1, STA2, and STA3, and the measurement setting identifier=1 and the measurement instance identifier=2. STA1 may send a perception measurement report frame to the AP, and report the perception measurement result with the measurement setting identifier=1 and the measurement instance identifier=1.

The AP can establish measurement settings with STA2 and STA3 at the same or different time points, and the measurement setting identifier=2. AP can send perception measurement polling frame, perception announcement frame and perception measurement frame to STA1, STA2, STA 3 at the same time, measurement setting identification=1 and measurement instance identification=3. The AP can send a perception measurement polling frame, a perception announcement frame and a perception measurement frame to STA2 and STA 3 at the same time, with the measurement setting ID=2 and the measurement instance ID=4. STA3 may send a perception measurement report frame to the AP, and report the perception measurement result with the measurement setting identifier=1 and the measurement instance identifier=1. STA2 may send a perception measurement report frame to the AP, and report the perception measurement result with the measurement setting identifier=1 and the measurement instance identifier=1.

5. Non-trigger frame-based (non-TB) measurement process

In some cases, only one pair of devices performs sensing measurements, ie a non-TB measurement procedure is used.

As shown in Figure 6a, if the sensing initiating device is a sensing signal transmitting device (Transmitter), the sensing signal transmitting device may send an NDPA frame to announce the start of measurement, and send an NDP frame after the SIFS time. The sensing signal receiving device (Receiver) receives the NDP frame to generate a measurement result, and after the SIFS time, the sensing signal receiving device reports the measurement result to the sensing initiating device such as measurement feedback_1 (Measurement feedback_1).

As shown in Figure 6b, if the sensing initiating device is a sensing signal receiving device, the sensing signal sending device may send an NDPA frame to announce the start of measurement, and send an NDP frame after the SIFS time. The sensing signal receiving device receives the NDP frame and generates a measurement result without reporting the measurement result.

6. Measurement process based on trigger frame (Trigger Based, TB)

In some cases, multiple devices participate in perception measurement, and to improve efficiency, a TB measurement process is generally adopted. The process may include polling (Polling), uplink measurement (Uplink, sensing sounding, UL), downlink measurement (Downlink, sensing sounding, DL) and key update (Key update). As shown in Figure 6c, STA1 and STA2 are sensing transmitters (Sensing Transmitter), and STA3, STA 4, and STA 5 are sensing receiving devices (Sensing Receiver).

In the polling (Polling) stage, the AP sends a polling trigger frame to detect whether the participating devices are available. During the uplink measurement (UL sensing sounding) phase, the AP sends trigger frames and NDP frames. In the downlink measurement (DL sensing sounding) AP sends NDPA frames and NDP frames.

Polling should always be here to check the availability of responder STAs before performing the actual sensing measurement.

STA1-STA 4 sends a permission to send frame (Clear To Send-to self, CTS-to-self) to respond to the polling frame, confirming that he can participate in the upcoming perception measurement (Here STA1-4 respond with CTS-to-self to confirm they will participate in upcoming sensing sounding.).

STA 5 did not respond to the CTS-to-self frame, so the AP will not include STA5 in the upcoming sensing measurement (STA5 does not send CTS-to-self back, so AP will not include STA5 in upcoming sensing sounding.) .

Optionally, there is an uplink measurement, provided that at least one sensing transmitter responds in the polling (UL sensing sounding is optionally present, conditioned on at least one sensing transmitters responds in the polling.).

AP sends TF (Trigger Frame, trigger frame) to STA1-STA2 to request NDP packet transmission for uplink measurement (AP sends a TF to STA1-2 to solicit NDP packet transmission to do UL sensing sounding.).

NDP from STA1-STA2 can be in UL (Uplink, uplink)-MIMO (Multiple-Input Multiple-Output, multiple input and multiple output)/UL (Uplink, uplink)-OFDMA (Orthogonal Frequency Division Multiple Access, orthogonal frequency division) at the same time Multiple access) to be transmitted (NDP from STA1-2 could be transmitted simultaneously in UL-MIMO/UL-OFDMA).

Optionally, there is a downlink measurement, provided that at least one sensing receiving device responds in the polling (DL sensing sounding is optionally present, conditioned on at least one sensing transmitters receiver in the polling.).

AP sends NDPA+NDP to STA3-STA4 to perform downlink measurement (AP sends NDPA+NDP to STA3-4 to perform DL sensing sounding).

If the secure long training field (Long Training Field, LTF) information needs to be updated and communicated with STAs, key update is optionally present if secure LTF info needs to be updated and communicated to STAs.

The updated information can be carried in an action or management frame (The updated information can be carried in an action or management frame).

7. Reporting process

In perception measurement, the measurement result is explicitly requested by the perception initiating device (triggered by the sensory feedback request frame or sensory report trigger frame as in the above point 6) or implicitly requested to report (triggered by NDP as in the above point 5) of. The measurement results can be reported immediately (immediate report) or delayed report (delayed report). Delayed reporting is generally explicitly requested by the perception initiating device.

As shown in Figure 7, in the reporting phase, the sensing signal sending device sends a feedback trigger (Trigger) frame after sending the NDP frame, and the sensing signal receiving device is such as receiving device_1 (Receiver_1), receiving device_2 (Receiver_2), receiving device_ After receiving the trigger frame, n (Receiver_n) etc. report the measurement results to the sensing signal sending device, such as measurement feedback_1 (Measurement feedback_1), measurement feedback_2 (Measurement feedback_2), measurement feedback_n (Measurement feedback_n), etc.

Fig. 8 is a schematic flowchart of a communication method 800 according to an embodiment of the present application. The method can optionally be applied to the system shown in Fig. 1, but is not limited thereto. The method includes at least some of the following.

S810. The communication device sends and/or receives a measurement frame, where the measurement frame is used for perception measurement.

In this embodiment of the present application, the measurement frame may also be referred to as a perception measurement frame.

In the embodiment of this application, a new measurement frame is adopted, which is different from the NDP frame mentioned in the above 6 points, and can support old version STAs such as HT STA, VHT STA, HE STA, etc. to participate in perception measurement (also called participation perception or participation measurement).

In an implementation manner, the communication device may be an access point (AP for short). The access point station may send the measurement frame to the non-access point station (which may be referred to as STA). Access point stations may also receive measurement frames from non-access point stations.

In one embodiment, the communication device may be a non-access point station. The non-AP station may send measurement frames to the AP station. Non-AP stations may also receive measurement frames from AP stations.

In one embodiment, the measurement frame is an Action frame or an Action No Ack frame. Wherein, the measurement frame is an action frame, which means that the measurement frame needs a block confirmation request and/or confirmation frame. The measurement frame is a non-acknowledgment action frame, which means that the measurement frame does not need a block acknowledgment request (BlockAckReq) and an acknowledgment (Ack) frame, which can improve measurement efficiency.

In one embodiment, the action field of the measurement frame includes a field representing at least one of the following:

Action category, used to indicate that the current frame is a public action frame;

Public action subclass, used to indicate that the current frame is a measurement frame;

Padding, the length of which is determined according to the processing time required by the sensing signal receiving device.

For example, in the action field of the current frame, a value of 4 in the Category field indicates that the frame is a Public Action frame, and a value of 51 to 255 in the Public Action field A value in the range can indicate that the frame is a measurement frame. The filling field can be 0 or greater than 0, and the length of the filling field can be determined according to the processing time required by the sensing signal receiving device, for example, the length of the filling field will be longer if the sensing signal receiving device needs longer processing time. This processing time may be indicated at the time of awareness capability exchange.

In one embodiment, the measurement frame is a Clear To Send-to self (CTS-to-Self) frame. The CTS-to-Self frame is a control frame, which does not require a response and will not cause the STA state to change.

In one embodiment, the measurement frame is a null (Null) frame or a quality of service null (QoS Null) frame. Null frames or QoS Null frames are data frames.

In an implementation manner, the measurement procedure of the communication device is determined based on the device role.

For example, the measurement initiating device and the measurement signal receiving device may pre-estimate the data volume of the measurement result data according to the relevant parameters of the measurement settings (such as the bandwidth of the measurement signal and the number of spatial streams of the measurement signal). If the length of the measurement report frame to be formed by the measurement result exceeds the maximum Media Access Control (MAC) frame length (maximum MPDU length) supported by the target device (such as the perception initiator) receiving the measurement report frame, send the measurement The resulting device (such as a sensing signal receiving device) needs to perform fragment processing on the measurement result.

In one embodiment, the method further includes: when the sensing initiating device finds that a segment is missing when receiving the last segment or does not receive a new segment within the first time, the sensing initiating device passes Measurement Result Request Frame—requests for unreceived segments.

For another example, if the sensing initiating device finds that among the n segments that need to be reported, the jth and kth segments are missing, it can request the sensing signal receiving device to report the jth segment, and then request the sensing signal receiving device to report the The kth segment.

1. Overall process

The embodiment of the present application relates to a perception setting establishment procedure, a perception measurement procedure and a perception reporting procedure. Among them, the perception setting establishment process can modify the frame format. The perception measurement process is divided into the measurement process initiated by the AP (as shown in 1.1) and the measurement process initiated by the non-AP STA (referred to as STA) (as shown in 1.2). The perception reporting process is divided into request-based reporting (solicited report, as shown in 1.3.1) and non-request-based reporting (unsolicited report, as shown in 1.3.2).

Wherein, the AP and the STA determine their respective roles in the measurement in the process of establishing the perception setting, and then determine a specific measurement process. Optionally, when the AP is the sensing initiating device and there are multiple sensing responding devices, it may also indicate that it is a sequential measurement process or a multi-user measurement process.

For example, the AP is the sensing initiating device, and the AP requests to establish measurement settings. The AP is the sensing signal sending device and the sensing signal receiving device in the measurement, and the STA is the sensing signal sending device and the sensing signal receiving device in the measurement. The corresponding measurement process is as follows: Bidirectional (I2R and R2I) measurements initiated by the AP are shown in Figure 18, Figure 19, Figure 22, Figure 25, Figure 27, Figure 30 and Figure 32.

For another example, if the AP is the sensing initiating device, the AP requests to establish measurement settings, the AP is the sensing signal sending device during the measurement, and the STA is the sensing signal receiving device during the measurement, then the corresponding measurement process is a one-way (I2R) measurement initiated by the AP. , as shown in Figure 20, Figure 23, Figure 26, Figure 28, Figure 31 and Figure 33.

For another example, if the AP is the sensing initiating device, the AP requests to establish measurement settings, the AP is the sensing signal receiving device during the measurement, and the STA is the sensing signal sending device during the measurement, then the corresponding measurement process is a one-way (R2I) measurement initiated by the AP. , as shown in Figure 21, Figure 24, Figure 29 and Figure 34.

For another example, the STA is the sensing initiating device, the STA requests to establish measurement settings, the STA is the sensing signal sending device and the sensing signal receiving device in the measurement, and the AP is the sensing signal sending device and the sensing signal receiving device in the measurement, then the corresponding measurement process Bidirectional (I2R and R2I) measurements initiated by STA, as shown in Figure 35, Figure 36, Figure 39 and Figure 40.

For another example, if the STA is the sensing initiating device, the STA requests to establish measurement settings, the STA is the sensing signal sending device during the measurement, and the AP is the sensing signal receiving device during the measurement, then the corresponding measurement process is a one-way (I2R) measurement initiated by the STA , as shown in Figure 37.

For another example, if the STA is the sensing initiating device, the STA requests to establish measurement settings, the STA is the sensing signal receiving device during the measurement, and the AP is the sensing signal sending device during the measurement, then the corresponding measurement process is a one-way (R2I) measurement initiated by the STA , as shown in Figure 38.

Optionally, during the establishment process of the sensing setting, the sensing initiating device will also determine the timeout period of each measurement instance in the measurement setting, that is, the I2R measurement and/or R2I measurement of each measurement instance needs to be sent or received after the measurement request frame How long after that, otherwise the measurement instance cannot produce valid measurement results. Optionally, the timeout period may be predefined and not indicated in the measurement settings. Optionally, the timeout period can also be set separately in the measurement instance, that is, it can be indicated in the measurement request frame of the corresponding measurement instance.

Optionally, in the process of establishing the sensing setting, the sensing initiating device will also determine the reporting method of the measurement result in each measurement instance in the measurement setting, that is, request-based reporting and/or non-request-based reporting.

In the technical solution, one measurement instance includes perception measurement and measurement report, and one measurement instance can be completed by multiple TXOPs. Generally, the sensing measurement process and measurement reporting are completed in different TXOPs. If there are many sensing and responding devices, the sensing measurement process may also be completed by multiple TXOPs, and the measurement reporting may also be completed by multiple TXOPs. Generally, this measurement report is completed before the next measurement instance starts. Optionally, in the process of establishing the sensing setting, the sensing initiating device will determine the maximum delay in reporting the results of the measurement results in each measurement instance in the measurement setting, such as the latest reporting time.

1.1. AP initiates measurement

In the two-way measurement initiated by the AP, the execution sequence of I2R measurement and R2I measurement may change. The AP first obtains the transmission opportunity and then performs I2R measurement first, and the STA first obtains the transmission opportunity and performs R2I measurement first.

In the multi-user two-way measurement initiated by the AP, the R2I measurement sequence of different STAs may also change, and the STA that obtains the transmission opportunity first will perform the R2I measurement first. It is also possible that a certain STA performs R2I measurement first, then the AP performs I2R measurement, and then other STAs perform R2I measurement.

1.1.1, HT STA participates in the measurement

As shown in Figure 18, in HT STA bidirectional (I2R and R2I) measurement, AP sends a measurement request (Measurement Request) frame to HT STA1, and HT STA1 returns an acknowledgment (Ack) frame to AP. The AP sends a measurement (Measurement) frame such as HT PPDU to HT STA1, and HT STA1 returns an acknowledgment (Ack) frame to the AP. HT STA1 sends a measurement frame such as HT PPDU to AP, and AP returns an acknowledgment (Ack) frame to HT STA1.

HT STA1 sends a measurement frame such as HT PPDU to AP, and AP returns an acknowledgment (Ack) frame to HT STA1. AP sends a measurement frame such as HT PPDU to HT STA1, and HT STA1 returns an acknowledgment (Ack) frame to AP.

As shown in FIG. 18 and FIG. 19 , in the two-way measurement initiated by the AP, the execution order of the I2R measurement and the R2I measurement may vary. If the AP obtains the transmission opportunity first, it will perform I2R measurement first, and if the STA first obtains the transmission opportunity, it will first perform R2I measurement.

As shown in Figure 20, in HT STA one-way (I2R) measurement, AP sends a measurement request frame to HT STA1, and HT STA1 returns an acknowledgment (Ack) frame to AP. AP sends a measurement frame such as HT PPDU to HT STA1, and HT STA1 returns an acknowledgment (Ack) frame to AP.

As shown in Figure 24, in the VHT STA one-way (R2I) measurement, the AP sends a measurement request frame to the VHT STA2, and the VHT STA2 returns an acknowledgment (Ack) frame to the AP. VHT STA2 sends a measurement frame such as VHT SU PPDU to AP, and AP returns an acknowledgment (Ack) frame to VHT STA2.

Optionally, the AP can use VHT MU PPDU to send I2R measurement signals to multiple VHT STAs using different spatial streams (ss) to improve measurement efficiency, as shown in Figure 25 and Figure 26.

As shown in Figure 25, in VHT STA multi-user two-way (I2R and R2I) measurement, AP sends a measurement request frame to VHT STA2, and VHT STA2 returns an acknowledgment (Ack) frame to AP; AP then sends a measurement request to VHT STA3 frame, VHT STA3 returns an acknowledgment (Ack) frame to the AP.

When the measurement frame adopts the Action No Ack type frame, the block confirmation request (BlockAckReq) and confirmation (Ack) frames are not required, which will further improve the measurement efficiency.

1.1.3, HE STA participates in the measurement

1.1.4, mixed (HT, VHT and HE STA) participation measurement

When HT STA, and/or VHT STA, and/or HE STA exist in the system at the same time, since VHT STA is compatible and supports HT PPDU, and HE STA is compatible and supports VHT PPDU and HT PPDU, the PPDU used for perception measurement can be as follows options:

If a VHT STA participates in the measurement and no HT STA participates in the measurement, the measurement frame is always sent in VHT SU PPDU or VHT MU PPDU format, see 1.1.2.

Option 2: Use the highest version of the PPDU supported by each STA according to the type of each STA. For example, the HT STA measurement frames are sent in the HT PPDU format, the VHT STA measurement frames are sent in the VHT SU PPDU format, and the HE STA measurement frames are sent in the HE SU PPDU format, see 1.1.4. If there are multiple VHT STAs and/or HE STAs, the VHT STA measurement frames can also be sent in the VHT MU PPDU format, see 1.1.2, and the HE STA measurement frames can also be sent in the HE MU PPDU format , see 1.1.3.

Option 3: A compromise approach. For example, the HT STA measurement frames are sent in the HT PPDU format, and the VHT STA and HE STA measurement frames are always sent in the VHT SU PPDU or VHT MU PPDU format.

Option 4: The sensing initiating device determines the PPDU format used by the measurement frames of each VHT STA and/or HE STA in different measurement settings according to different requirements. As an embodiment, the PPDU format of the measurement frame received and sent by each STA can be specified respectively. For example, in measurement setting 1, the measurement frame sent by the AP to VHT STA 1 adopts the VHT SU PPDU format, and VHT STA 1 sends it to the AP. The measurement frames are in HT PPDU format. As a special embodiment, for the two-way measurement initiated by the AP, the sensing initiating device does not specify the PPDU format of the measurement frame sent by each STA, and the PPDU format of the measurement frame sent by each STA is the same as the PPDU format of the measurement frame sent by the sensing initiating device Be consistent. For example, in measurement setting 2, the measurement frame sent by the AP to VHT STA 1 adopts the HT PPDU format, and the measurement frame sent by VHT STA 1 to the AP also adopts the HT PPDU format.

As shown in Figure 32, in the mixed sequential bidirectional (I2R and R2I) measurement of multiple STAs (HT STA, VHT STA, and HE STA), the AP sends a measurement request frame to HT STA1, and HT STA1 returns an acknowledgment (Ack )frame. AP sends a measurement frame such as HT PPDU to HT STA1, and HT STA1 returns an acknowledgment (Ack) frame to AP. HT STA1 sends a measurement frame such as HT PPDU to AP, and AP returns an acknowledgment (Ack) frame to HT STA1. The AP sends a measurement request frame to the VHT STA2, and the VHT STA2 returns an acknowledgment (Ack) frame to the AP. The AP sends a measurement frame such as a VHT SU PPDU to the VHT STA2, and the VHT STA2 returns an acknowledgment (Ack) frame to the AP.

The AP sends a measurement frame such as a VHT SU PPDU to the VHT STA2, and the VHT STA2 returns an acknowledgment (Ack) frame to the AP. The AP sends a measurement request frame to the HE STA4, and the HE STA4 returns an acknowledgment (Ack) frame to the AP. The AP sends a measurement frame such as HE SU PPDU to the HE STA4, and the HE STA4 returns an acknowledgment (Ack) frame to the AP.

HT STA1 sends a measurement frame such as HT PPDU to AP, and AP returns an acknowledgment (Ack) frame to HT STA1. The AP sends a measurement request frame to the VHT STA2, and the VHT STA2 returns an acknowledgment (Ack) frame to the AP. VHT STA2 sends a measurement frame such as VHT SU PPDU to AP, and AP returns an acknowledgment (Ack) frame to VHT STA2. The AP sends a measurement request frame to the HE STA4, and the HE STA4 returns an acknowledgment (Ack) frame to the AP. HE STA4 sends a measurement frame such as HE SU PPDU to AP, and AP returns an acknowledgment (Ack) frame to HE STA4.

In particular, if there are stations in the system that support the currently defined WLAN sensing process (such as sensing stations, SENS STA), and there are stations of the old version of this solution (such as HT STA, VHT STA, and HE STA), if SENS STA Also supports the process and frame of this solution, then the station can also be correspondingly equivalent to a HT STA, or VHT STA, or HE STA.

1.2. Non-AP STA initiates measurement

In the two-way measurement initiated by the non-AP STA, the execution sequence of I2R measurement and R2I measurement may also change. The AP first obtains the transmission opportunity and performs R2I measurement first, and the STA first obtains the transmission opportunity and performs I2R measurement first.

As shown in Figure 35, when HT STA initiates two-way (I2R and R2I) measurement, HT STA1 sends a measurement request frame to AP, and AP returns an acknowledgment (Ack) frame to HT STA1. HT STA1 sends a measurement frame such as HT PPDU to AP, and AP returns an acknowledgment (Ack) frame to HT STA1. The AP sends a measurement (Measurement) frame such as HT PPDU to HT STA1, and HT STA1 returns an acknowledgment (Ack) frame to the AP.

As shown in Figure 36, when HT STA initiates two-way (I2R and R2I) measurement, HT STA1 sends a measurement request frame to AP, and AP returns an acknowledgment (Ack) frame to HT STA1. AP sends a measurement frame such as HT PPDU to HT STA1, and HT STA1 returns an acknowledgment (Ack) frame to AP.

VHT STA2 sends a measurement frame such as VHT SU PPDU to AP, and AP returns an acknowledgment (Ack) frame to VHT STA2. AP sends a measurement (Measurement) frame such as VHT SU PPDU to VHT STA2, and VHT STA2 returns an acknowledgment (Ack) frame to AP.

HE STA4 sends a measurement frame such as HE SU PPDU to AP, and AP returns an acknowledgment (Ack) frame to HE STA4. The AP sends a measurement frame such as HE SU PPDU to the HE STA4, and the HE STA4 returns an acknowledgment (Ack) frame to the AP.

The HE STA can also initiate one-way (I2R) measurement and/or one-way (R2I) measurement, which will not be repeated here.

1.3. Reporting of measurement results

Generally, both the measurement initiating device and the measurement signal receiving device can pre-estimate the data volume of the measurement result data according to the relevant parameters of the measurement settings (such as the bandwidth of the measurement signal, the number of spatial streams of the measurement signal). If the length of the report frame to be formed by the measurement result exceeds the maximum Media Access Control (MAC) frame length (maximum MPDU length) supported by the device receiving the report frame (such as the perception initiator device), the device sending the measurement result ( For example, a sensing signal receiving device) needs to perform fragment processing on the measurement results. According to the actual amount of data, it may generally be divided into 8 segments, or 16 segments, or 32 segments, or 64 segments. Except for the last segment, each of the other segments forms a report frame whose length is the aforementioned maximum MAC frame length. The length of the report frame formed by the last segment may be smaller than the aforementioned maximum MAC frame length, which is determined according to the length of the actual measurement result. For example, if the above-mentioned maximum MAC frame length is 4095 bytes, and the data of a certain measurement result is 8000 bytes, then the measurement result is divided into 2 segments to form 2 reporting frames, the length of the first frame is 4095 bytes, and the length of the second frame is 4095 bytes. The length of the two frames is less than 4095 bytes. Report frames formed by multiple segments of the same measurement result will be actively reported or requested one by one.

1.3.1. Request-based reporting

As shown in Figure 41, in the case of segmentation, the AP can request the STA to report the measurement results, and the sensing initiating device (such as the AP) requests the measurement results of a certain sensing signal receiving device (such as STA1) in a certain measurement instance of each segment. AP sends a report request (Report Request) frame to STA1 for requesting segment 1 (query segment1), and STA1 returns an acknowledgment (Ark) frame to AP. STA1 sends a measurement report (Measurement Report) frame to the AP, which includes the AP requested segment (contans queried segment). The AP sends a report request frame to STA1 again for requesting segment n (query segment n), and STA1 returns an acknowledgment (Ark) frame to the AP. STA1 sends a measurement report (Measurement Report) frame to the AP, which includes the AP requested segment (contans queried segment).

As shown in Figure 42, in the case of no segmentation, the AP can request the STA to report the measurement result, which may specifically include: the AP sends a report request (Report Request) frame to STA1, and STA1 returns an acknowledgment (Ark) frame to the AP. STA1 sends a no segment measurement report (Measurement Report) frame to the AP.

In this embodiment of the application, the format of the report request (Report Request) frame can refer to the following description about the measurement result request frame.

As shown in Figure 43, in the case of segmentation, STA can request AP to report measurement results, for example, the sensing initiating device (such as STA1) requests the measurement of a certain sensing signal receiving device (such as AP) in a certain measurement instance The individual segments of the result. STA1 sends a report request (Report Request) frame to the AP for requesting segment 1 (query segment1), and the AP returns an acknowledgment (Ark) frame to STA1. The AP sends a measurement report (Measurement Report) frame to STA1, which includes the AP requested segment (contans queried segment). STA1 sends a report request frame to AP again for requesting segment n (query segment n), and AP returns an acknowledgment (Ark) frame to STA1. The AP sends a measurement report (Measurement Report) frame to STA1, which includes the AP requested segment (contans queried segment).

As shown in Figure 44, in the case of no segmentation, the STA can request the AP to report the measurement result, which may specifically include: STA1 sends a report request (Report Request) frame to the AP, and the AP returns an acknowledgment (Ark) frame to STA1. The AP sends a no-segment measurement report (Measurement Report) frame to STA1.

1.3.2. Non-request-based reporting

As shown in Figure 45, a certain sensing signal receiving device (such as STA1) in a certain measurement instance reports each segment of its own measurement results to the sensing initiating device (such as AP). If the sensing initiating device finds that a segment is missing when it receives the last segment, or if it has not received a new segment for a long time, the sensing initiating device can request the unreceived segments one by one. Specifically, STA1 sends a measurement report frame to the AP, which includes segment 1 (contans segment1). STA1 sends a measurement report frame to the AP, which includes segment n (contans segment n). After the AP receives segment n, it finds that segment x is lost. The AP sends a report request frame to STA1 for requesting the missing segment x (query missing segment x). STA1 returns an acknowledgment frame to the AP. STA1 sends a measurement report frame to the AP, which includes a segment requested by the AP (contans queried segment).

As shown in Figure 46, when there is no segmentation, the STA can actively report the measurement results to the AP. For example, STA1 sends a no segment (no segment) measurement report (Measurement Report) frame to the AP.

As shown in FIG. 47 , a certain sensing signal receiving device (eg, AP) in a certain measurement instance reports each segment of its own measurement result to the sensing initiating device (eg, STA1 ). If the sensing initiating device finds that a segment is missing when it receives the last segment, or if it has not received a new segment for a long time, the sensing initiating device can request the unreceived segments one by one. Specifically, the AP sends a measurement report frame to STA1, which includes segment 1 (contans segment1). The AP sends a measurement report frame to STA1, which includes segment n (contans segment n). After receiving segment n, STA1 finds that segment x is lost. STA1 sends a report request frame to the AP for requesting the missing segment x (query missing segment x). The AP returns an acknowledgment frame to STA1. The AP sends a measurement report frame to STA1, which includes the AP requested segment (contans queried segment).

As shown in Figure 48, when there is no segmentation, the AP can actively report the measurement results to the STA. For example, the AP sends a no segment (no segment) measurement report (Measurement Report) frame to STA1.
