Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The network architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.

Referring to fig. 1, a schematic diagram of a network architecture of a communication system according to an embodiment of the present application is shown. The network architecture may include: station 10 and access point 20.

The number of stations 10 is typically multiple, and each access point 20 may be associated with one or more stations 10. The Station 10 may include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of User Equipment (UE), mobile Station (MS), terminal devices (terminal devices), etc. For convenience of description, in the embodiment of the present application, the above-mentioned devices are collectively referred to as a station STA.

The Access Point 20 is a device deployed in an Access network to provide wireless communication functions for the station 10, and may also be referred to as an AP (Access Point). The access point 20 may include various forms of wireless routers, wireless switches, wireless relay devices, or the like.

Optionally, not shown in fig. 1, the network architecture further includes other network devices, such as: gateway devices, and the like.

Association and communication between the station 10 and the access point 20 may be via wireless local area network technology, such as communication based on IEEE 802.11 protocols.

The IEEE 802.11BF working group is discussing the formulation of protocols to specify how WLAN awareness can be achieved using WLAN signals compliant with the IEEE 802.11 protocol. The WLAN terminals participating in the awareness may have roles of awareness session initiator, awareness session responder, awareness signal sender, awareness signal receiver, etc.

The WLAN aware session includes one or more of the following phases: session establishment, perception measurement, perception reporting, session termination. The WLAN terminal may have one or more roles in a sensing session, for example, the sensing session initiator may be just the sensing session initiator, may be the sensing signal sender, may be the sensing signal receiver, and may be both the sensing signal sender and the sensing signal receiver.

Session establishment phase: a perception session is established, a perception session participant and its role (including a perception signal sender and a perception signal receiver) are determined, a perception session related operational parameter is determined, and the parameter is optionally interacted between terminals. That is, upon establishment of a aware session, the terminals may need to negotiate aware roles and operational parameters one by one or the terminals declare their own roles and operational parameters (e.g., through beacon frames or other special frames).

Sensing and measuring stage: the sensing measurement is performed and the sensing signal sender sends a sensing signal to the sensing signal receiver.

And a perception reporting stage: reporting the measurement results, as determined by the application scenario, the perceived signal receiver may need to report the measurement results to the perceived session initiator.

Session termination phase: the terminal stops the measurement and terminates the sensing session.

In order to successfully complete WLAN sensing measurements, the sensing signal receiver needs to receive the sensing signal sent by the sensing signal sender, but in actual deployment, there may be a "hidden node" phenomenon: one station cannot detect the presence of a media competitor due to too far distance, i.e. both stations a and B are associated to the same access point, but stations a and/or B cannot directly receive the other's signal (typical examples are stations a and B spatially distributed on both sides of the access point's signal coverage). For example, during a WLAN awareness session, the AP determines that station a transmits an awareness signal to station B, however, station B cannot receive the awareness signal due to the relatively large distance between station a and station B. That is, the "hidden node" phenomenon may cause the sensing signal to be "unreachable", so that the sensing measurement fails, and the stability of the system during the WLAN sensing session is affected.

In the scheme shown in the subsequent embodiment of the application, before or when the sensing session is established, a method is provided for determining that a sensing signal receiver participating in the sensing session can receive a sensing signal from a sensing signal sender, so that the probability of failure of sensing measurement in the sensing session process is reduced.

Referring to fig. 2, a flowchart of a request processing method according to an embodiment of the present application is shown. The method may be interactively performed by a aware session initiation device, a probe transmission device, and a probe transmission device, where the aware session initiation device, the probe transmission device, and the probe transmission device may be terminals or access point devices in the network architecture shown in fig. 1. The method may comprise the steps of:

at step 201, at least one probe transmitting device transmits a probe request to at least one probe receiving device.

In embodiments of the present application, a probe transmitting device in a WLAN network may send a probe request to a probe receiving device to detect whether a signal it transmits is reachable to the probe receiving device before a aware session is established.

The detection and transmission device can be used as a candidate perception signal sender in the follow-up perception session process; the above-described probing reception device may be a candidate for a perceived signal receiver during a subsequent perceived session.

At step 202, at least one probe receiving device receives a probe request sent by at least one probe sending device.

In the embodiment of the application, when a probe receiving device sends a probe request to a probe sending device, if the probe request sent by the probe sending device is reachable to the probe receiving device, the probe receiving device may receive the probe request sent by the probe sending device.

Step 203, the sensing session initiation device receives a detection report; the probe report is transmitted by at least one probe transmitting device and/or at least one probe receiving device; the probe report is used for indicating the receiving condition of the probe receiving device on the probe request sent by the probe sending device.

In the embodiment of the present application, based on the receiving situation of the probe request sent by the at least one probe receiving device to the at least one probe sending device, the probe sending device and/or the probe receiving device may send a probe report to the sensing session initiation device, so as to notify the sensing session initiation device of the reachability of the probe request sent by each probe sending device to each probe receiving device.

Wherein when the probe report is transmitted by the probe receiving apparatus, the probe receiving apparatus may transmit the probe report based on a response condition of the probe transmitting apparatus to the probe request transmitted thereto (such as whether the response is received, and contents of the received response, etc.).

Wherein, after the awareness session initiating device acquires the above-mentioned probing report, a WLAN awareness session can be created based on the probing report.

In summary, in the scheme shown in the embodiment of the present application, the probe sending device in the WLAN network may send a probe request to the probe receiving device, and based on the receiving condition of the probe receiving device on the probe request sent by the probe sending device, the probe receiving device and/or the probe sending device report a probe report to the sensing session initiating device, so that the sensing session initiating device can learn the accessibility of the signal sent by the probe sending device to the probe receiving device, and the subsequent sensing session initiating device may establish the WLAN sensing session based on the learned accessibility, so that the probability that the sensing measurement fails due to the fact that the sensing signal is "unreachable" can be reduced, and the stability of the system in the WLAN sensing session process is improved.

Based on the embodiment shown in fig. 2, the WLAN-aware session is established in the present application in two stages: the first stage is an information acquisition stage, and the second stage is a session information negotiation stage. The first stage is completed and includes, but is not limited to, collecting signal reachability information of the perceived session participants (i.e., the probe transmitting device and the probe receiving device described above). The second stage selects proper perception signal sender and perception signal receiver based on the information collected in the first stage, negotiates the relevant parameter of the conversation, and establishes the perception conversation.

The process in the first stage can be divided into three sub-processes, namely, a detection process establishment sub-process, a detection sub-process and a detection report reporting sub-process. The implementation flow of the above three sub-processes may refer to the subsequent embodiments of the present application.

Referring to fig. 3, a flowchart of a request processing method according to an embodiment of the present application is shown. The method may be interactively performed by a aware session initiation device, a probe transmission device, and a probe transmission device, where the aware session initiation device, the probe transmission device, and the probe transmission device may be terminals or access point devices in the network architecture shown in fig. 1. The method may comprise the steps of:

step 301, a sensing session initiation device sends a probe setup request to at least one probe sending device; accordingly, the probe transmitting device receives the probe establishment request sent by the probe aware session initiation device.

In one possible implementation, the sensing that the session initiation device should send a probe setup request to at least one of the probe sending devices includes:

the sensing session initiating device sends the detection establishing request to at least one detection sending device in a multicast mode;

Or the sensing session initiating device sends the probe establishment request to at least one of the probe sending devices in a unicast mode.

In the embodiment of the application, the sensing session initiating device may send a probe establishment request to one or more probe sending devices simultaneously in a multicast manner, so as to request to establish a probe flow before the WLAN sensing session is established. Alternatively, the session initiation aware device may send probe setup requests to one or more probe sending devices in a unicast manner.

Wherein, the at least one probing transmitting device may be a candidate sensing signal sender in a subsequent WLAN sensing session establishment process. The at least one probing sending device may be selected by the session initiation device according to a certain rule, or may also be selected randomly by the session initiation device.

For example, taking the awareness of a session initiation device as an AP and the sounding transmission device as a terminal (such as an STA), the AP may randomly select one or more STAs from among STAs in the WLAN network as the sounding transmission device.

Step 302, at least one probe transmitting device transmits a probe setup response to a perception session initiating device; accordingly, the aware session initiation device receives a probe setup response sent by at least one of the probe sending devices.

The aware session initiation device is further configured to determine whether the probe sending device confirms participation in a probe procedure based on the probe setup response.

In the embodiment of the application, after receiving the probe establishment request, the probe sending device may send a response to the session initiation device to indicate whether it determines to participate in a subsequent probe procedure.

In one possible implementation manner, the probe setup request includes at least one of probe time information and a probe relation; the probe relationship is used for indicating the corresponding relationship between the probe transmitting device and the probe receiving device.

In this embodiment of the present application, the above-mentioned probe setup request may indicate a time of a subsequent probe procedure, such as a start time, an end time, a probe duration, and so on, and in addition, the probe setup request may indicate which probe sending devices probe which probe receiving devices (i.e., a correspondence between probe sending devices and probe receiving devices).

In another possible implementation manner, when the probe transmitting device corresponding to the probe setup response indicates that the probe transmitting device is confirmed to participate in a probe flow, the sensing session initiation device transmits probe confirmation information to the probe transmitting device corresponding to the probe setup response; the detection transmitting equipment receives detection confirmation information transmitted by the perception session initiating equipment;

Wherein the detection confirmation information comprises detection time information and at least one of detection relations; the probe relationship is used for indicating the corresponding relationship between the probe transmitting device and the probe receiving device.

In another possible implementation manner of the embodiment of the present application, when the sensing session initiation device receives a probe setup response sent by a probe sending device and the probe setup response determines to participate in a subsequent probe procedure, the sensing session initiation device may send a probe acknowledgement message to the probe sending device.

The detection confirmation information may indicate time of a subsequent detection process, and may also indicate which detection transmitting devices detect which detection receiving devices.

Wherein when the probe confirmation information includes probe time information and at least one of the probe relations, the probe establishment request may not include the information; or when the probe establishment request contains probe time information and at least one item of probe relation, the probe confirmation information does not contain the information; alternatively, the aware session initiation device may not send the probe acknowledgement information described above when the probe setup request contains probe time information and at least one of the probe relations.

The steps 301 to 302 are a detection flow establishment sub-process in the first stage of the WLAN awareness session, and the detection flow establishment sub-process may be implemented in different manners based on different combinations of the steps and various possible implementations.

In one possible implementation, before the at least one probe transmitting device transmits a probe request to the at least one probe receiving device, the aware session initiation device transmits a probe trigger request to the at least one probe transmitting device; correspondingly, at least one sensing and transmitting device receives a detection trigger request sent by a sensing and session initiation device; the probe trigger request is used for triggering at least one probe transmitting device to transmit a probe request to at least one probe receiving device.

In another possible implementation manner of the embodiment of the present application, the above-mentioned probe request may also be triggered by the session initiation device to be sent after the establishment of the probe procedure.

In one possible implementation, the probe trigger request includes an identification of the probe transmitting device.

In this embodiment of the present application, the probe trigger request may include an identifier of the probe sending device, so as to instruct the corresponding probe sending device to send the probe request.

In one possible implementation manner, the sending a probe trigger request to at least one probe sending device includes: transmitting the probe trigger request to at least one of the probe transmitting devices by multicast;

or, the probe triggering request is sent to at least one probe sending device in a unicast mode.

In the embodiment of the application, the sensing session initiating device may send the probe trigger request to one or more probe sending devices simultaneously in a multicast manner, and may also send the probe trigger request to one or more probe sending devices in a unicast manner.

In one possible implementation, the probe trigger request is used to share a transmission opportunity of the aware session initiation device to at least one of the probe sending devices.

Correspondingly, sending a probe request to at least one probe receiving device includes:

at least one probe transmitting device transmits a probe request to at least one probe receiving device within the transmission opportunity shared by the probe trigger requests.

In the embodiment of the application, the sensing session initiation device may share the transmission opportunity obtained by its own contention to at least one probe sending device, so that the at least one probe sending device sends the probe request through the transmission opportunity shared by the sensing session initiation device.

In one possible implementation manner, the sending, to at least one of the probe receiving devices, a probe request within a transmission opportunity shared by the probe trigger requests includes:

transmitting a detection request to at least one detection receiving device in a transmission opportunity shared by the detection trigger request in a frequency division sharing mode;

or sending a detection request to at least one detection receiving device in the transmission opportunity shared by the detection trigger request in a time division sharing mode.

In this embodiment of the present application, the sensing session initiation device may share the transmission opportunity frequency spectrum obtained by its own contention to at least one sounding transmission device (i.e. the multiple sounding transmission devices respectively send the sounding request on different frequencies), or may share the transmission opportunity frequency spectrum obtained by its own contention to at least one sounding transmission device (i.e. the multiple sounding transmission devices respectively send the sounding request on different time domains).

In one possible implementation, at the same point in time, the receiving devices of the probe request sent by different probe sending devices are different.

In one possible implementation, the probe transmitting device transmits a probe request to at least one probe receiving device, including: the detection sending equipment sends a detection request to at least one detection receiving equipment in a multicast mode; or the probe sending device sends the probe request to at least one of the probe receiving devices in a unicast mode.

In the embodiment of the application, when the probe sending device sends the probe request, the probe request can be sent to one or more probe receiving devices simultaneously in a multicast mode, and the probe request can also be sent to one or more probe receiving devices in a unicast mode.

In one possible implementation manner, the sending, by unicast, a probe request to at least one of the probe receiving devices includes:

and respectively sending detection requests to at least one detection receiving device by a device discovery method of establishing a TDLS mode through a tunnel type direct link.

In the embodiment of the present application, when the probe sending device sends probe requests to one or more probe receiving devices in a unicast manner, the probe sending device may send probe requests to corresponding probe receiving devices based on a device discovery method in a TDLS manner.

In one possible implementation, the probe transmitting device may receive a probe request response, which is transmitted after the probe receiving device receives the probe request.

In the embodiment of the present application, when the probe receiving device receives a probe request response sent by a certain probe sending device, the probe request response may be sent to the probe sending device.

Wherein, the probe request response may include at least one of reachability confirmation information and signal quality information;

the signal reachability confirmation information is used for indicating the detection receiving equipment to receive the detection request sent by the detection sending equipment;

the signal quality information is used for indicating the signal quality of the detection request sent by the detection sending device and received by the detection receiving device

The step 303 is a detection sub-process of the first stage of the WLAN awareness session, and the detection sub-process may be implemented in different manners based on different combinations of the step 303 and various possible implementations.

2.1 Combined detection based on trigger frame

Referring to fig. 20, a trigger frame based joint detection flow chart according to an embodiment of the present application is shown. As shown in fig. 20, a perceived session initiator (AP) transmits an MU-RTS frame to candidate perceived signal transmitters (STA 1 and STA 2) to initiate a multi-user (MU) simultaneous transmission procedure, and STA1 and STA2 acknowledge in response to the CTS frame. In the multi-user simultaneous transmission process, a perception session initiator sends SDpoll frames to candidate perception signal transmitters to trigger an information detection flow, and one or more perception signal transmitters send SDreq frames in a multicast mode to detect. SDPoll frame structure is shown in fig. 21 and sdreq frame structure is shown in fig. 22.

Alternatively, if this is adopted, the detection result (i.e. the detection report) may be reported by the sensing signal receiver (excluding the sensing signal sender) or actively acquired by the sensing session initiator from the sensing signal receiver (excluding the sensing signal sender) during the subsequent reporting.

Alternatively, if the first sub-flow adopts the method of "Joint Based on Trigger Frame (Trigger Based)" or "acknowledged Joint Based on Trigger Frame" and no other Frame is transmitted between the first sub-flow and this step, the SDPoll Frame may adopt the Trigger Frame (Trigger Frame) already defined in IEEE 802.11 instead of the Frame structure of fig. 21.

As shown in fig. 21, a SENS Poll Frame is defined, which is a new Trigger (Trigger) Frame (Type 1 in Frame Control is denoted as a Control Frame, subtype 2 is denoted as a Trigger Frame), and Trigger Type value (any one of values 8 to 15) is used to indicate that the Trigger Frame is a SENS Poll Frame.

Poll Type field: 0 represents an SDPoll frame; 1 represents a SIReq frame; 2 to 15 percent.

The value of the Poll Type field is only an exemplary description given in the embodiment of the present application, and may be set to other values, as long as it is ensured that the values corresponding to different frame types are different.

User Info fields, information each representing a perceived signal sender, include AID12 (i.e., AID, written as AID12 for its effective length of 12 bits) and RU Allocation (containing allocated Resource Unit information).

As shown in FIG. 22, a SENS Action frame with a Sub Type of 4 is defined as an SDReq frame.

A Presence Bitmap field, a bit (bit) indicating whether an AID field exists; the other 7 bits (bits) remain.

AID field, the AID of the perception signal sender itself is used when the perception signal receiver reports information in the reporting process. Replacing the MAC address with AID during information reporting may reduce network traffic.

2.2 Combined detection)

Referring to fig. 23 and 24, a joint detection flow chart according to an embodiment of the present application is shown. As shown in fig. 23, a perceived session initiator (AP) transmits SDPoll frames in its own acquired transmission opportunity to trigger perceived signal senders one by one, and perceived signal senders transmit SDReq frames in a multicast manner to detect perceived signal recipients. As shown in fig. 24, the sensing signal transmitter transmits the SDReq frame in a multicast manner after freely contending for channel resources through EDCA to detect the sensing signal receiver. SDPoll frame structure is as in fig. 25 or fig. 26 or fig. 27, and sdreq frame structure is as in fig. 22.

Optionally, if this is done, the reporting process reports the detection result from the perceived signal receiver (excluding the perceived signal sender) or the perceived session initiator actively obtains the detection result from the perceived signal receiver (excluding the perceived signal sender).

As shown in FIG. 25, a SENS Action frame with a Sub Type of 2 is defined, an SDpoll frame.

As shown in fig. 26, a SENS Poll Frame is defined, which is a new Control Frame (Type 1 in Frame Control is denoted as Control Frame) and a reservation value of 1 for Subtype can be used to indicate that the Control Frame is a SENS Poll Frame.

As shown in fig. 27, a SENS Poll Frame is defined, which is a new Trigger (Trigger) Frame (Type 1 in Frame Control is denoted as a Control Frame, subtype 2 is denoted as a Trigger Frame), and Trigger Type value (any one of values 8 to 15) is used to indicate that the Trigger Frame is a SENS Poll Frame.

User Info field the User Info List contains only one User Info field (which differs from fig. 20) and information indicating a sender of the perceived signal, including AID12 (i.e., AID12 written for its effective length of 12 bits) and RU Allocation.

2.3 Sequential sounding in Shared transmission opportunity (Shared TXOP)

Referring to fig. 28, a sequential probing flowchart in a shared transmission opportunity according to an embodiment of the present application is shown. In fig. 28, a sensing session initiator (AP) sends a transmission opportunity Sharing trigger frame (TXOP Sharing TF) in its own obtained transmission opportunities to share its own transmission opportunity to a candidate sensing signal sender, where the sensing signal sender sends an SDReq frame one by one in the shared transmission opportunities, and the sensing signal receiver responds to the SDResp frame. The SDReq frame structure is shown in fig. 22, and the sdresp frame structure is shown in fig. 33.

Optionally, if this is adopted, the reporting process may report the detection result by the sensing signal receiver and/or the sensing signal sender, or the sensing session initiator may actively acquire the detection result from the sensing signal receiver and/or the sensing signal sender.

Alternatively, if the first sub-process is actually performed, the TXOP Sharing TF frame may use the MU-RTS TXS frame already defined by the IEEE 802.11be protocol. Otherwise, the TXOP Sharing TF frame may adopt a frame structure as shown in fig. 29, 30, 31, and 32.

As shown in fig. 29, the MU-RTS TXS frame (Trigger Type value of 3) already defined by the IEEE 802.11be protocol is modified, and the reserved field is used to define the TXOP Sharing TF frame of the present scheme.

SubType 0 represents the underlying TXS frame (i.e., the MU-RTS TXS frame of the original IEEE 802.11be protocol); 1 represents SENS Discovery TXS frames (i.e., TXOP Sharing TF frames used in the present scheme); 2 to 15 percent.

The value of the Sub Type field is only an exemplary description given in the embodiment of the present application, and may be set to other values, as long as it is ensured that the values corresponding to different frame types are different.

Number of IDs there are several valid IDs in Common in the Common Info and User Info fields. 0 means that ID0 is valid; 1 indicates that ID0 and ID1 are valid; 2 indicates that ID0 and ID1 and ID2 are valid; 3 indicates that ID0 and ID1 and ID2 and ID3 are valid.

ID of the perceived signal receiver (here, AID), the correspondence of AID to MAC address may be specified in advance by an out-of-band method.

The TXOP Sharing TF includes the function of SD Poll. The SD Poll shown in fig. 27 is used for joint detection (i.e., perceiving that a sender of a signal is transmitting a multicast frame, not for a certain receiver, and thus no receiver ID needs to be specified), the frame structure shown in fig. 27 is a frame structure of a trigger frame, and the User Info of the trigger frame is information of a target STA of the trigger frame specified by the standard, and thus includes an AID of the perceiving sender. On the other hand, based on the frame structure shown in fig. 29, the sensing signal transmitters will transmit the probe signals (sequentially) to the receivers one by one, so the sensing signal transmitters need to know which receivers should be transmitted to, and thus the frame structure shown in fig. 29 includes the IDs of the sensing signal receivers.

As shown in fig. 30, another modification is made to the MU-RTS TXS frame already defined by the IEEE 802.11be protocol, and the reserved field is used to define the TXOP Sharing TF frame of the present scheme.

SubType 0 represents the underlying TXS frame (i.e., the MU-RTS TXS frame of the original IEEE 802.11be protocol); 1 denotes a SENS TXS frame (i.e., a TXOP Sharing TF frame used in the present scheme); 2 to 15 percent.

Receiver Address Hi the upper 32 bits (bits) of the MAC address of a candidate perceptual signal receiver.

Receiver Address Low the lower 16 bits (bits) of the MAC address of the candidate sense signal receiver.

As shown in fig. 31, a new Trigger frame is defined, a SENS TXS frame (represented by any one of Trigger Type values 8 to 15).

Sub Type 0 represents SENS Discovery TXS frames (i.e., TXOP Sharing TF frames used in the present scheme); 1 to 15.

The value of the subtype field is only an exemplary description given in the embodiment of the present application, and may be set to other values, so long as SENS Discovery TXS frames can be uniquely indicated.

Number of Receiver Address there are several MAC addresses of the sense signal receivers in common in the Trigger Dependent Common Info field.

Receiver Address, the MAC Address of the Receiver of the perception signal.

As shown in fig. 32, a new Trigger frame is defined, a SENS TXS frame (represented by any one of Trigger Type values 8 to 15).

Number of Receiver Address there are several MAC addresses of the sense signal receivers in common in the Trigger Dependent User Info field.

Receiver Address, the MAC Address of the Receiver of the perception signal.

As shown in FIG. 33, a SENS Action frame with a Sub Type of 5, an SDResp frame, is defined.

SNR field: the signal-to-noise ratio of the SDReq signal received by the receiver of the sense signal.

AID field, the AID of the perception signal receiver itself is used when the perception signal sender reports information in the reporting process.

2.4 Non-responsive sequential probing in shared transmission opportunities)

Referring to fig. 34, a flow chart of non-responsive sequential probing in a shared transmission opportunity according to an embodiment of the present application is shown. As shown in fig. 34, a sensing session initiator (AP) sends a transmission opportunity Sharing trigger frame (TXOP Sharing TF) in its own obtained transmission opportunities to share its own transmission opportunity to a candidate sensing signal sender, and the sensing signal sender sends an SDReq frame one by one in the shared transmission opportunities. The SDReq frame structure is shown in fig. 22.

In this way, the reporting process may report the detection result by the perceived signal receiver (excluding the perceived signal sender) or actively acquire the detection result from the perceived signal receiver (excluding the perceived signal sender) by the perceived session initiator.

Alternatively, if the first sub-procedure is actually performed, the TXOP Sharing TF frame may use the MU-RTS TXS frame already defined by the IEEE 802.11be protocol. Otherwise, the TXOP Sharing TF frame may adopt a frame structure as in fig. 29 or fig. 30 or fig. 31 or fig. 32.

2.5 Sequential probing in Frequency-Division (Frequency-Division) shared transmission opportunities

Referring to fig. 35, a sequential sounding flow chart in a frequency division shared transmission opportunity according to an embodiment of the present application is shown. As shown in fig. 35, the sensing session initiator (AP) transmits an MU-RTS frame to candidate sensing signal transmitters (STA 1 and STA 2) to start a frequency division Multiple User (MU) simultaneous transmission procedure, and STA1 and STA2 acknowledge in response to the CTS frame. In a multi-user simultaneous transmission process, one or more of the sense signal transmitters simultaneously transmit the SDReq frame to different candidate sense signal receivers, which simultaneously respond to the SDResp. The SDReq frame structure is shown in fig. 22, and the sdresp frame structure is shown in fig. 33.

If this is the case, the reporting process may report the detection result by the perceived signal receiver and/or perceived signal sender, or the perceived session initiator may actively obtain the detection result from the perceived signal receiver and/or perceived signal sender.

Alternatively, this method may be changed to a non-responsive detection method, and reference may be made to a non-responsive sequential detection procedure in the shared transmission opportunity.

2.6 Sequential probing in Time-Division (Time-Division) shared transmission opportunities

Referring to fig. 36, a sequential sounding flow chart in a time division shared transmission opportunity according to an embodiment of the present application is shown. As shown in fig. 36, a perceived session initiator (AP) transmits an MU-RTS frame to candidate perceived signal transmitters (STA 1 and STA 2) to initiate a time division multi-user (MU) transmission procedure, and STA1 and STA2 acknowledge in response to the CTS frame. In a multi-user sequential transmission process, one or more of the sense signal transmitters transmits an SDReq frame to different candidate sense signal receivers, which respond to the SDResp. The SDReq frame structure is shown in fig. 22, and the sdresp frame structure is shown in fig. 33.

This approach may also be changed to non-responsive, and reference may be made to non-responsive sequential probing flows in a shared transmission opportunity.

2.7 TDLS sounding in shared transmission opportunity

Referring to fig. 37, a TDLS sounding flow chart in a shared transmission opportunity according to an embodiment of the present application is shown. As shown in fig. 37, the sensing session initiator sends a transmission opportunity Sharing trigger frame (TXOP Sharing TF) in its own obtained transmission opportunities to share its own transmission opportunity to a candidate sensing signal sender, where the sensing signal sender sends TDLS Discovery Response frames one by one in the shared transmission opportunities, and the sensing signal receiver may or may not respond TDLS Discovery Response frames.

If the method is adopted, the reporting process can report the detection result by the perception signal receiver or actively acquire the detection result from the perception session initiator to the perception signal receiver. Optionally, the sensing signal sender may report the detection result, and the sensing session initiator may also actively acquire the detection result from the sensing signal sender.

During a multi-user sequential transmission, one or more of the sense signal transmitters transmit TDLS Discovery Response frames to different candidate sense signal receivers, which may or may not respond TDLS Discovery Response.

Step 304, at least one sensing transmission device transmits a detection report to the sensing session initiation device; the probe report is used for indicating the receiving condition of the probe receiving device on the probe request sent by the probe sending device.
