[0041] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. For the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0042] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), or other communication systems, etc.

[0043] Exemplarily, the communication system 100 to which the embodiments of the present application are applied is as Figure 1 shown. The communication system 100 may include an Access Point (AP) 110, and a Station (STA) 120 that accesses the network through the access point 110.

[0044] In the embodiments of the present application, the STA may be a Mobile Phone, a Pad, a computer with wireless transceiver function, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless device in industrial control, a wireless device in self driving, a wireless device in remote medical, a wireless device in smart grid, a wireless device in transportation safety, a wireless device in smart city, or a wireless device in smart home, etc.

[0045] Figure 1 Exemplarily, one AP and two STAs are shown. Optionally, the communication system 100 may include multiple APs and other numbers of STAs, which are not limited in the embodiments of the present application.

[0046] It should be understood that in the embodiments of the present application, devices with communication functions in the network / system may be referred to as communication devices. Taking Figure 1 the shown communication system 100 as an example, the communication devices may include an access point 110 and a station 120 with communication functions. The access point 110 and the station 120 may be the specific devices described above, which will not be elaborated here; the communication devices may also include other devices in the communication system 100, such as other network entities like network controllers, gateways, etc., which are not limited in the embodiments of the present application.

[0047] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article merely describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this article generally represents an "or" relationship between the associated objects before and after.

[0048] It should be understood that the "indication" mentioned in the embodiments of the present application may be a direct indication, an indirect indication, or may also represent an association relationship. For example, A indicates B, which may mean that A directly indicates B. For example, B can be obtained through A; it may also mean that A indirectly indicates B. For example, A indicates C, and B can be obtained through C; it may also mean that there is an association relationship between A and B.

[0049] In the description of the embodiments of the present application, the term "corresponding" may represent a direct or indirect corresponding relationship between two parties, may also represent an association relationship between the two parties, or may also be relationships such as indication and being indicated, configuration and being configured, etc.

[0050] The "STA" described in the embodiments of the present application may specifically be a "non-AP STA (non-AP STA)".

[0051] In the embodiments of the present application, "predefined" can be implemented by pre-saving corresponding codes, tables, or other means that can be used to indicate relevant information in devices (such as including access points and stations). The present application does not limit its specific implementation manner. For example, predefined may refer to those defined in the protocol.

[0052] To facilitate understanding of the technical solutions of the embodiments of the present application, the following explains relevant terms of the present application.

[0053] Association Identifier (AID), which is used to identify a terminal after establishing an association with an access point.

[0054] Medium Access Control (MAC). That is, the abbreviation of the media access control address.

[0055] Transmission Opportunity (TXOP) refers to a period of time during which a terminal having this transmission opportunity can initiate one or more transmissions actively.

[0056] WLAN Sensing senses people or objects in the environment by measuring the changes in the WLAN signals scattered and / or reflected by people or objects. That is, WLAN Sensing measures and senses the surrounding environment through wireless signals, so as to complete many functions such as detecting whether there are people intruding, moving, falling, etc. in the room, posture recognition, and establishing a three-dimensional image of the space.

[0057] WLAN devices participating in WLAN sensing may include the following roles:

[0058] Sensing Initiator, also known as the sensing initiating device, is a device that initiates a sensing session and wants to obtain sensing results;

[0059] Sensing Responder, also known as the sensing responding device, is a device other than the Sensing Initiator that participates in the sensing session;

[0060] Sensing Transmitter, also known as the sensing transmitting device, is a device that initiates a sensing illumination signal;

[0061] Sensing Receiver, also known as the sensing receiving device, is a device that receives a sensing illumination signal;

[0062] Sensing processor is a device that processes sensing measurement results;

[0063] Sensing Participant includes the Sensing Initiator, the Sensing Transmitter, and the Sensing Receiver.

[0064] A WLAN terminal may have one or more roles in a sensing session. For example, a sensing session initiating device can be just a sensing session initiating device, or it can become a sensing signal transmitting device, or it can become a sensing signal receiving device, or it can be both a sensing signal transmitting device and a sensing signal receiving device at the same time.

[0065] For example, as Figure 2 shown in A of

[0066] For another example, as Figure 2 shown in B of

[0067] For another example, as Figure 2 shown in C of

[0068] For another example, as Figure 2 shown in D of

[0069] For another example, as Figure 2As shown by E in [reference], STA1 can be a Sensing Initiator, a Sensing Transmitter, or a Sensing Processor; STA2 can be a Sensing Receiver; STA3 can be a Sensing Receiver.

[0070] For another example, as Figure 2 shown by F in [reference], STA1 can be a Sensing Initiator; STA2 can be a Sensing Receiver or a Sensing Processor; STA3 can be a Sensing Transmitter; STA4 can be a Sensing Transmitter.

[0071] For another example, as Figure 2 shown by G in [reference], STA1 can be a Sensing Initiator, a Sensing Transmitter, a Sensing Receiver, or a Sensing Processor.

[0072] For another example, as Figure 2 shown by H in [reference], STA1 can be a Sensing Initiator; STA2 can be a Sensing Transmitter, a Sensing Receiver, or a Sensing Processor.

[0073] For another example, as Figure 2As shown in I, STA1 can be a Sensing Initiator, a Sensing Transmitter, a Sensing Receiver, or a Sensing Processor; STA2 can be a Sensing Transmitter or a Sensing Receiver.

[0074] For another example, as Figure 2 shown in J, STA1 can be a Sensing Initiator or a Sensing Processor; STA2 can be a Sensing Transmitter or a Sensing Receiver; STA3 can be a Sensing Transmitter or a Sensing Receiver. In some embodiments, there can be multiple Sensing Types. For example, a Sensing Type based on Channel State Information (CSI), i.e., CSI-based Sensing, which obtains a sensing measurement result by processing the CSI of the received sensing measurement signal. For another example, a Sensing Type based on reflected signals, i.e., Radar-based Sensing, which obtains a sensing measurement result by processing the reflected signals of the received sensing measurement signal.

[0075] A WLAN sensing session includes one or more of the following stages: session establishment, sensing measurement, sensing reporting, and session termination.

[0076] Session establishment stage: Establish a sensing session, determine the sensing session participants and their roles (including the sensing signal transmitter and the sensing signal receiver), decide on the operation parameters related to the sensing session, and optionally, interact this parameter between terminals.

[0077] Sensing measurement stage: Conduct sensing measurement, and the sensing signal transmitter sends a sensing signal to the sensing signal receiver.

[0078] Sensing reporting stage: Report the measurement results. Depending on the application scenario, the sensing signal receiver may need to report the measurement results to the sensing session initiator.

[0079] Session termination phase: The terminal stops measuring and terminates the sensing session.

[0080] When establishing a sensing session, the terminals may need to negotiate the sensing roles and operation parameters one by one, or a terminal declares its own roles and operation parameters (e.g., through beacon frames or other special frames).

[0081] The amount of data of the sensing measurement results is usually relatively large. For example, the data of the channel state information (CSI) for one measurement may reach 4K - 40K bits. To reduce the network load caused by reporting the sensing measurement results, a measurement threshold can be set. When the change amount between the current 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.

[0082] The sensing session initiating device can set multiple groups of measurement parameters. One group of measurement parameters (identified by a measurement setup ID, which can be equivalent to a burst group) can be applied to multiple measurements (identified by a measurement instance ID, which can be equivalent to a burst).

[0083] In the related art, the specific process of establishing a sensing session when the sensing session initiating device initiates a sensing session has not been discussed. For example, how to determine whether to execute the interaction process of the sensing parameter negotiation frame, and the specific process of ending the sensing session, such as whether to execute the frame interaction process of releasing the sensing parameters, etc.

[0084] In view of this, the embodiments of the present application provide a method for establishing a sensing session. The sensing session initiating device can determine the target sensing session establishment process to be executed according to the type of the target sensing session to be established. For example, the type of the target sensing session can be indicated by the service primitive of the MLME - SAP interface. And a method for ending a sensing session is provided. The sensing session initiating device or the sensing session responding device can determine the target sensing session ending process to be executed according to the type of the sensing session to be ended. For example, the information of the target sensing session to be ended is indicated by providing the MLME - SAP interface primitive.

[0085] Figure 3 It is a schematic flowchart of method 200 for wireless communication according to an embodiment of the present application. The method 200 is a schematic diagram of a method for establishing a sensing session. As Figure 3 shown, the method 200 includes the following:

[0086] S210. The session initiation device for sensing executes a target sensing session establishment process according to the type of the target sensing session to be established.

[0087] In some embodiments, the type of the target sensing session may be a pairwise negotiation type or a negotiation type, or may also be a non-pairwise negotiation type or a non-negotiation type, such as an opportunistic type, a monostatic radar type, or a passive type.

[0088] It should be understood that for a sensing session of the non-pairwise negotiation type, the session initiation device for sensing does not need to negotiate the sensing session parameters and can execute sensing measurements.

[0089] For example, for a sensing session of the opportunistic type, the session initiation device for sensing listens to any physical protocol data unit (PPDU) on the working channel and performs measurements.

[0090] For example, for a sensing session of the monostatic radar type, the session initiation device for sensing needs to send a sensing signal and receive the reflected signal of the signal to perform measurements.

[0091] For example, for a sensing session of the passive type, the session initiation device for sensing needs to obtain the measurement time information in the beacon frame and listen to the specific PPDUs for sensing sent by other STAs during this time period to perform measurements.

[0092] It should be understood that the embodiments of the present application can be applicable to establishing a new sensing session, or can also be applicable to establishing a new measurement in an existing sensing session. Therefore, in some embodiments, S210 can be replaced with:

[0093] The session initiation device for sensing executes a target sensing session establishment process according to the type of the sensing session corresponding to the measurement to be established.

[0094] That is to say, establishing a new sensing session or establishing a new measurement in an existing sensing session can both execute the corresponding sensing session establishment process according to the type of the sensing session. That is, the target sensing session can be a new sensing session, or can also be an existing sensing session, or in other words, an established sensing session.

[0095] For example, if the target sensing session is of the paired negotiation type, the sensing session initiating device allocates resources for the target sensing session and / or sends a first request frame to the sensing session responding device, where the first request frame is used to request the establishment of measurements for the target sensing session.

[0096] For another example, if the target sensing session is of the non-paired negotiation type, the sensing session initiating device allocates resources for the non-paired negotiation type sensing session.

[0097] In some embodiments, the sensing session initiating device allocating resources for the target sensing session may include: the sensing session initiating device allocates resources for subsequent execution of sensing measurements for the target sensing session, such as resources for the sensing transmitting device to send measurement signals, such as frequency resource units, space-time stream allocation information, etc. Alternatively, it may also include storage resources for storing measurement results, and this application is not limited thereto.

[0098] In some embodiments, the first request frame may be used to request the establishment of one measurement or multiple measurements in the target sensing session.

[0099] In some embodiments, the first request frame is also referred to as a measurement establishment request frame.

[0100] In some embodiments, the sensing session initiating device indicates the type of the target sensing session through a media access control sublayer management entity service access point (MAC sublayer management entity service access point, MLME-SAP) interface service primitive.

[0101] In some embodiments, the establishment process of the target sensing session may be based on an indication from the upper-layer application of the sensing session initiating device. For example, when it is confirmed that a target sensing session needs to be established, the upper-layer application of the sensing session initiating device calls an interface provided by the Station Management Entity (SME) to initiate the sensing session establishment process. Specifically, the upper-layer application calls the interface provided by the SME, and thus the SME calls the first media access control sublayer management entity service access point (MAC sublayer management entity service access point, MLME-SAP) interface primitive to implement the establishment of the sensing session.

[0102] In some embodiments, the upper-layer application may refer to an application above the MAC layer, such as a Wi-Fi driver or a wpa_supplicant tool class application, etc.

[0103] In some embodiments, the first MLME-SAP interface primitive, or the sensing request establishment primitive, is denoted as MLME-SENSSETUP.request.

[0104] In some embodiments, the first MLME-SAP interface primitive is used to indicate the type of the target sensing session. Alternatively, the first MLME-SAP interface primitive is used to indicate to perform a corresponding sensing session establishment process according to the type of the target sensing session. For example, initiate sensing measurements and / or send a first request frame.

[0105] In some embodiments, the first MLME-SAP interface primitive is used to indicate at least one of the following:

[0106] The type of the target sensing session, the session identifier of the target sensing session, the measurement establishment identifier, the duration of the measurement, the number of repetitions of the measurement, the interval time of the measurement, the sensing request parameters, where the sensing request parameters include the identity identifier of the sensing session response device, the parameters of the sensing session to be negotiated, etc.

[0107] By way of example and not limitation, the first MLME-SAP interface primitive can be expressed as:

[0108] MLME-SENSSETUP.request(

[0109] Type,

[0110] Dialog Token,

[0111] Measurement Setup ID,

[0112] Duration,

[0113] Number of Repetitions,

[0114] Interval,

[0115] SENS Request Set,

[0116] VendorSpecificInfo )

[0118] Wherein, the Type field represents the type of the sensing session, or rather, the sensing type.

[0119] For example, a value of 0 indicates an Opportunistic type, a value of 1 indicates a Monostatic radar type, a value of 2 indicates a Passive type, and a value of 3 indicates a Pairwise negotiation type.

[0120] Dialog Token field: Indicates the session identifier of the sensing session to be established.

[0121] Measurement Setup ID field: Indicates the identifier of the measurement setup to be established.

[0122] Duration field: Indicates the duration of the measurement.

[0123] Number of Repetitions field: Indicates the number of repetitions of the measurement.

[0124] SENS Request Set field: Indicates the identifier of the peer device and the parameters of the sensing session to be negotiated. For example, Associated ID (AID), Unassociated ID (UID), or MAC address.

[0125] VendorSpecificInfo field: Indicates vendor-specific information.

[0126] After the SME of the sensing session initiating device indicates the sensing type of the target sensing session to the MAC sublayer management entity (MLME) of the sensing session initiating device in the first MLME SAP receive primitive, the MLME can execute the corresponding sensing session establishment process according to the type of the target sensing session.

[0127] Hereinafter, the specific implementation of the target sensing session establishment process will be described in combination with the type of the target sensing session.

[0128] Embodiment 1: The type of the target sensing session is a non-pairwise negotiation type.

[0129] For example, an Opportunistic type, a Monostatic radar type, or a Passive type.

[0130] In this case, the MLME of the sensing session initiating device notifies the MAC sublayer of the sensing session initiating device of the resources required for the target sensing session of this type, and / or the MLME of the sensing session initiating device sends first indication information to the SME of the sensing session sending device, where the first indication information is used to indicate the establishment result of the target sensing session, such as successful establishment or failure.

[0131] In Embodiment 1, the sensing session initiating device may be a station device, for example, a non-AP STA, or may also be an access point device.

[0132] In some embodiments, the first indication information may also be implemented through MLME-SAP interface primitives. It is denoted as MLME-SENSSETUP.confirm.

[0133] In some embodiments, the first indication information may be used to indicate at least one of the following:

[0134] The session identifier corresponding to the target sensing session, the measurement establishment identifier, the status code, the sensing request parameters.

[0135] Among them, the status code is used to indicate the establishment result of the target sensing session, such as successful establishment or establishment failure.

[0136] By way of example and not limitation, the MLME-SENSSETUP.confirm may be expressed as:

[0137] MLME-SENSSETUP.confirm(

[0138] Dialog Token,

[0139] Measurement Setup ID,

[0140] Status,

[0141] SENS Request Set,

[0142] VendorSpecificInfo )

[0144] Among them, the Dialog Token field: indicates the session identifier of the target sensing session.

[0145] The Measurement Setup ID field: indicates the identifier of the measurement establishment.

[0146] The Status field: indicates the establishment result of the sensing session.

[0147] As an example, a value of 1 indicates successful establishment, and a value of 0 indicates failed establishment.

[0148] SENS Request Set field: Indicates the parameters of the sensing session.

[0149] VendorSpecificInfo field: Indicates vendor-specific information.

[0150] Embodiment 2: The type of the target sensing session is a paired negotiation type.

[0151] In this case, the MLME of the sensing session initiating device notifies the MAC sublayer of the sensing session initiating device to allocate resources for the target sensing session of this type, and / or the MLME of the sensing session initiating device sends a first request frame to the sensing session responding device.

[0152] In this Embodiment 2, the sensing session initiating device may be a station device, for example, a non-AP STA, and the sensing session responding device may be an access point device, or the sensing session initiating device may be an access point device, and the sensing session responding device may be a station device, such as a non-AP STA.

[0153] In some embodiments, the first request frame includes a session ID and / or a measurement setup ID. Among them, the session ID may refer to the session ID corresponding to the sensing session to be established, and the measurement setup ID may refer to the measurement setup ID corresponding to the measurement setup to be established.

[0154] Hereinafter, in combination with a specific scenario, the identifiers carried in the first request frame will be described.

[0155] Case 1:

[0156] The target sensing session corresponds to one measurement setup, or rather, the session establishment phase of the target sensing session only includes one measurement setup frame interaction process.

[0157] In this case, the measurement setup ID, or the session ID, may be carried in the first request frame. The measurement setup ID may be the measurement setup ID corresponding to this one measurement setup in the target sensing session, and the session ID is the session ID of the target sensing session.

[0158] Optionally, there is one or more sensing sessions (including the target sensing session) between the sensing session initiating device and the sensing session responding device, and each sensing session corresponds to an independent session ID.

[0159] In this Case 1, the measurement establishment identifier and the session identifier are in one-to-one correspondence, or the measurement establishment identifier and the session identifier are the same.

[0160] Optionally, in Case 1, the Dialog Token field in the first MLME-SAP interface primitive can also be used to indicate the measurement establishment identifier.

[0161] Case 2:

[0162] The target awareness session corresponds to multiple measurement establishments, or rather, the session establishment phase of the target awareness session includes multiple measurement establishment frame interaction processes. There is only one awareness session between the awareness session initiating device and the awareness session responding device, that is, there is only the target awareness session between the awareness session initiating device and the awareness session responding device.

[0163] In this case, the first request frame can carry the measurement establishment identifier, excluding the session identifier, or it can also carry the measurement establishment identifier and the session identifier. The measurement establishment identifier can be the measurement establishment identifier corresponding to the target measurement establishment to be established in the target awareness session. There are also other measurement establishments in the target awareness session.

[0164] Optionally, the target awareness session can be an established awareness session (denoted as Case 2-1), or it can also be an awareness session to be established (denoted as Case 2-2).

[0165] Optionally, in this Case 2-1 and Case 2-2, the first request frame can carry only the measurement establishment identifier. For example, if there is currently no awareness session between the awareness session initiating device and the awareness session responding device (such as an awareness session has never been established, or the established awareness session has ended), in this case, a new awareness session is implicitly established when establishing the measurement; if there is currently an awareness session between the awareness session initiating device and the awareness session responding device, the new measurement establishment belongs to the current awareness session.

[0166] Optionally, in this Case 2-1 and Case 2-2, the first request frame can carry the measurement establishment identifier and the session identifier. If the awareness session initiating device explicitly indicates the session identifier, the session identifier also needs to be explicitly carried at the end of the subsequent measurement and the end of the session.

[0167] Optionally, in Case 2, the first MLME-SAP interface primitive may not include the Dialog Token field, or the value of the Dialog Token field is a reserved value.

[0168] Case 3:

[0169] The target perception session corresponds to multiple measurement establishments, or rather, the session establishment phase of the target perception session includes multiple measurement establishment frame interaction processes. In this case, there are multiple perception sessions (including the target perception session to be established) between the perception session initiating device and the perception session responding device.

[0170] In this case, the session identifier and the measurement establishment identifier are carried in the first request frame. The session identifier is the session identifier of the target perception session, and the measurement establishment identifier is the measurement establishment identifier corresponding to the measurement establishment to be established in the target perception session.

[0171] Optionally, in case 3, the target perception session is an established perception session between the perception session initiating device and the perception session responding device, and the measurement establishment to be established is a new measurement establishment in the established perception session.

[0172] Optionally, in case 3, the target perception session is a newly established perception session between the perception session initiating device and the perception session responding device, and the measurement establishment to be established is a new measurement establishment in the newly established perception session.

[0173] It should be understood that in the embodiments of the present application, a measurement establishment frame interaction process may refer to an interaction process of a measurement establishment request frame and a measurement establishment response frame, and a measurement establishment frame interaction process can be used to establish a measurement establishment.

[0174] After the perception session responding device receives the first request frame from the perception session initiating device, in some embodiments, the method 200 further includes:

[0175] The perception session responding device allocates resources for the target perception session and / or sends a first response frame to the perception session sending device, and the first response frame is used to indicate measurement establishment response information.

[0176] In some embodiments, the perception session responding device allocating resources for the target perception session may include: the perception session responding device allocates resources for subsequent execution of perception measurements for the target perception session, or may also include storage resources for storing measurement results, and the present application is not limited thereto.

[0177] In some embodiments, the first response frame is also called the measurement establishment response frame.

[0178] In some embodiments, after the perception session responding device receives the first request frame, the MLME of the perception session responding device sends third indication information to the SME of the perception session responding device, and the third indication information is used to indicate that the perception session responding device has received the first request frame sent by the perception session initiating device.

[0179] In some embodiments, the third indication information may also be implemented through MLME-SAP interface primitives.

[0180] In some embodiments, the primitive corresponding to the third indication information may be referred to as a sensing establishment notification primitive, denoted as MLME-SENSSETUP.indication.

[0181] In some embodiments, the third indication information may be used to indicate at least one of the following:

[0182] The type of sensing session, session identifier, measurement establishment identifier, duration of measurement, number of measurement repetitions, measurement interval, sensing request parameters, where the sensing request parameters include parameters of the sensing session.

[0183] In some implementation manners, the MLME-SENSSETUP.indication may be expressed as:

[0184] MLME-SENSSETUP.indication(

[0185] Type,

[0186] Dialog Token,

[0187] Measurement Setup ID,

[0188] Duration,

[0189] Number of Repetitions,

[0190] Interval,

[0191] SENS Request Set,

[0192] VendorSpecificInfo )

[0194] Among them, the Type field represents the type of sensing session, or rather, the sensing type.

[0195] For example, a value of 0 represents the Opportunistic type, a value of 1 represents the Monostatic radar type, a value of 2 represents the Passive type, and a value of 3 represents the Pairwise negotiation type.

[0196] Dialog Token field: Indicates the session identifier of the sensing session to be established.

[0197] Measurement Setup ID field: Indicates the identifier of the measurement setup to be established.

[0198] Duration field: Indicates the duration of the measurement.

[0199] Number of Repetitions field: Indicates the number of repetitions of the measurement.

[0200] SENS Request Set field: Indicates the identifier of the sensing session response device and the parameters of the sensing session to be negotiated. For example, Associated ID (AID), Unassociated ID (UID), or MAC address.

[0201] VendorSpecificInfo field: Indicates vendor-specific information.

[0202] Further, the SME of the sensing session response device invokes the second MLME-SAP interface primitive to instruct the MLME of the sensing session response device to notify the media access control MAC sublayer of the sensing session response device to allocate resources for the target sensing session, and / or the MLME of the sensing session response device sends a first response frame to the sensing session initiating device.

[0203] In some embodiments, the second MLME-SAP interface primitive is used to indicate at least one of the following:

[0204] The session identifier of the target sensing session, the measurement setup identifier, the feedback information of the sensing session response device for the measurement setup, the sensing response parameters, where the sensing response parameters are used to indicate the parameters determined by the sensing session response device for establishing the sensing session.

[0205] In some embodiments, the second MLME-SAP interface primitive or the sensing setup response primitive is denoted as MLME-SENSSETUP.response.

[0206] By way of example and not limitation, the MLME-SENSSETUP.response can be expressed as:

[0207] MLME-SENSSETUP.response(

[0208] Dialog Token,

[0209] Measurement Setup ID,

[0210] Status,

[0211] SENS Request Set,

[0212] VendorSpecificInfo )

[0214] Among them, the Dialog Token field: Indicates the identifier of the target awareness session.

[0215] The Measurement Setup ID field: Indicates the identifier of the measurement setup.

[0216] The Status field: Used to indicate the feedback information of the awareness session response device regarding the measurement setup.

[0217] As an example, for instance, 0 indicates Accept, and 1 indicates Reject.

[0218] The SENS Response Set field: Indicates the parameters of the awareness session determined by the awareness session response device.

[0219] Optionally, when the status code indicates Accept, this SENS response parameter field exists; otherwise, this SENS response parameter field may be included.

[0220] In some embodiments, the SME of the awareness session response device invokes the second MLME - SAP interface primitive, which can be based on an indication from an upper - layer application. For example, the upper - layer application schedules the interface provided by the SME, so that the SME invokes the second MLME - SAP interface primitive.

[0221] In some embodiments, the first response frame includes a measurement setup identifier and / or a session identifier. Among them, the session identifier may refer to the session identifier corresponding to the awareness session confirmed to be established by the awareness session response device, and the measurement setup identifier may refer to the measurement setup identifier corresponding to the measurement setup confirmed to be established by the awareness session response device.

[0222] Next, in combination with a specific scenario, the identifiers carried in the first response frame are described in detail.

[0223] Case 1:

[0224] The target perception session corresponds to a measurement establishment. Or rather, the session establishment phase of the target perception session only includes a measurement establishment frame interaction process.

[0225] In this case, the first response frame may carry a measurement establishment identifier or a session identifier. The measurement establishment identifier may be the measurement establishment identifier corresponding to the one measurement establishment in the target perception session, and the session identifier is the session identifier of the target perception session.

[0226] Optionally, there is one or more perception sessions (including the target perception session) between the perception session initiating device and the perception session responding device, where each perception session corresponds to an independent session identifier.

[0227] In Case 1, the measurement establishment identifier and the session identifier are in one-to-one correspondence, or the measurement establishment identifier and the session identifier are the same.

[0228] Optionally, in Case 2, the session token field in the second MLME-SAP interface primitive can also be used to indicate the measurement establishment identifier.

[0229] Case 2:

[0230] The target perception session corresponds to multiple measurement establishments. Or rather, the session establishment phase of the target perception session includes multiple measurement establishment frame interaction processes. There is only one perception session between the perception session initiating device and the perception session responding device, that is, there is only the target perception session between the first device and the second device.

[0231] In this case, the first response frame carries the measurement establishment identifier and does not include the session identifier. Or, it can also carry the measurement establishment identifier and the session identifier. The measurement establishment identifier may be the measurement establishment identifier corresponding to the target measurement establishment to be established in the target perception session. There are also other measurement establishments in the target perception session.

[0232] Optionally, the target perception session may be an established perception session (denoted as Case 2-1), or it may also be a perception session to be established (denoted as Case 2-2).

[0233] Optionally, in Case 2-1 and Case 2-2, the first response frame may only carry the measurement establishment identifier. For example, if there is currently no perception session between the perception session initiating device and the perception session responding device (such as no perception session has been established before, or the established perception session has ended), in this case, a new perception session is implicitly established when measuring; if there is currently one perception session between the perception session initiating device and the perception session responding device, then the measurement establishment can be subordinate to the current perception session.

[0234] Optionally, in Case 2-1 and Case 2-2, the first response frame may carry a measurement establishment identifier and a session identifier. If the sensing session initiating device explicitly indicates the session identifier, the session identifier also needs to be explicitly carried at the end of subsequent measurements and at the end of the session.

[0235] Optionally, in Case 2, the second MLME-SAP interface primitive may not include a Dialog Token field, or the value of the Dialog Token field is a reserved value.

[0236] Case 3:

[0237] The target sensing session corresponds to multiple measurement establishments, or rather, the session establishment phase of the target sensing session includes multiple measurement establishment frame interaction processes. In this case, there are multiple sensing sessions (including the target sensing session to be established) between the sensing session initiating device and the sensing session responding device.

[0238] In this case, the session identifier and the measurement establishment identifier are carried in the first response frame. The session identifier is the session identifier of the target sensing session, and the measurement establishment identifier is the measurement establishment identifier corresponding to the measurement establishment to be established in the target sensing session.

[0239] Optionally, in Case 3, the target sensing session is an established sensing session between the sensing session initiating device and the sensing session responding device, and the measurement establishment to be established is a new measurement establishment for the established sensing session.

[0240] Optionally, in Case 3, the target sensing session is a newly established sensing session between the sensing session initiating device and the sensing session responding device, and the measurement establishment to be established is a new measurement establishment for the newly established sensing session.

[0241] In some embodiments, the method 200 further includes:

[0242] The MLME of the sensing session initiating device sends second indication information to the SME of the sensing session initiating device, and the second indication information is used to indicate that the sensing session initiating device has received the first response frame sent by the sensing session responding device.

[0243] In some embodiments, the second indication information is implemented through MLME-SAP interface primitives.

[0244] In some embodiments, the primitive corresponding to the second indication information or the sensing establishment confirmation primitive is denoted as MLME-SENSSETUP.confirm.

[0245] As an example and not by way of limitation, the MLME-SENSSETUP.confirm can be expressed as:

[0246] MLME-SENSSETUP.confirm(

[0247] Dialog Token,

[0248] Measurement Setup ID,

[0249] Status,

[0250] SENS Request Set,

[0251] VendorSpecificInfo )

[0253] Among them, the session token (Dialog Token) field: indicates the session identifier of the sensing session.

[0254] The measurement setup ID field: indicates the identifier of the measurement setup.

[0255] The status code (Status) field: indicates the establishment result of the sensing session. As an example, a value of 1 indicates successful establishment, and a value of 0 indicates establishment failure.

[0256] The sensing request parameter (SENS Request Set) field: indicates the parameters of the sensing session.

[0257] The vendor-specific information (VendorSpecificInfo) field: indicates the vendor-specific information.

[0258] Combined with Figure 4 , the overall process of establishing a sensing session in the embodiments of the present application is described.

[0259] It should be understood that Figure 4 For the implementation details in each of the steps shown, refer to the specific descriptions of the foregoing embodiments. For the sake of brevity, they are not repeated here.

[0260] As Figure 4 shown, it may include the following steps:

[0261] S301, when the upper-layer application of the sensing session initiating device confirms the establishment of the target sensing session, call the interface of the SME of the sensing session initiating device to indicate to the SME to establish the target sensing session.

[0262] In S302, the SME of the sensing session initiating device invokes the sensing establishment request primitive to instruct the MLME of the sensing session initiating device to execute the target sensing session establishment process according to the type of the target sensing session.

[0263] Among them, the sensing establishment request primitive can be used to indicate the type of the target sensing session to be established.

[0264] For example, if the target sensing session is of the non-paired negotiation type, the MLME of the sensing session initiating device notifies the MAC sublayer of the sensing session initiating device of the resources required for the target sensing session of this type, and / or the MLME of the sensing session initiating device sends the first indication information to the SME of the sensing session sending device, and the first indication information is used to indicate the establishment result of the target sensing session, such as successful establishment or failure.

[0265] Also for example, if the target sensing session is of the paired negotiation type, the MLME of the sensing session initiating device notifies the MAC sublayer of the sensing session initiating device to allocate resources for the target sensing session of this type, and / or the MLME of the sensing session initiating device sends a measurement establishment request frame to the sensing session response device.

[0266] In S303, when the target sensing session is of the paired negotiation type, the MLME of the sensing session initiating device sends a measurement establishment request frame to the MLME of the sensing session response device.

[0267] In S304, after the MLME of the sensing session response device receives the measurement establishment request frame, it notifies the SME of the sensing response device through the sensing establishment notification primitive that the sensing session response device has received the measurement establishment request frame sent by the sensing session initiating device.

[0268] In S305, the SME of the sensing session response device notifies the upper-layer application of the sensing session response device.

[0269] In S306, the upper-layer application of the sensing session response device sends confirmation information to the SME of the sensing session response device.

[0270] In S307, the SME of the sensing session response device instructs the MLME of the sensing session response device to allocate resources for the target sensing session and send a measurement establishment response frame to the sensing session initiating device through the sensing establishment response primitive.

[0271] In S308, after the MLME of the sensing session initiating device receives the measurement establishment response frame, it notifies the SME of the sensing session initiating device through the sensing establishment confirmation primitive that the sensing session initiating device has received the measurement establishment response frame sent by the sensing session response device.

[0272] In S309, the SME of the sensing session initiation device receives the measurement establishment response frame of the sensing session response device through the upper-layer application of the sensing session initiation device, thus achieving the establishment of the target sensing session.

[0273] Hereinafter, the frame format design of the first request frame and the first response frame will be described.

[0274] It should be understood that Figures 5 to 8 For the exemplified first request frame, the frame formats of the first response frame are only examples, and other frame formats obtained by transforming according to the frame formats of the examples of the present application all fall within the protection scope of the present application, and the present application is not limited thereto.

[0275] In some embodiments, the first request frame is implemented by an Action frame or an Action No Ack frame. That is, the measurement establishment request frame can be implemented by an Action frame or an Action No Ack frame.

[0276] In some embodiments, the first response frame is implemented by an Action frame or an Action No Ack frame. That is, the measurement establishment response frame can be implemented by an Action frame or an Action No Ack frame.

[0277] In some embodiments, at least one field in the Action frame or the Action No Ack frame can be used to indicate that the action frame or the action no ack frame is a measurement establishment request frame or a measurement establishment response frame.

[0278] That is, the first request frame and the first response frame can be regarded as sensing action frames.

[0279] In some embodiments, the Action frame or the Action No Ack frame includes an action domain field, and the action domain field includes a Category field, a Public Acton Field, and a SENS Subtype field. The Action frame or the Action No Ack frame can be indicated as a measurement establishment request frame or a measurement establishment response frame by the combined values of the Category field, the Public Acton Field, and the SENS Subtype field.

[0280] As an example, when the value of the action category field is 4, it indicates that this frame is a public action frame. When the value of the public action sub - category field is a reserved value (for example, any value within the range of 46 - 255, hereinafter, 46 is used as an example for illustration), it indicates that this frame is a sensing action frame. Further, by the value of the sensing sub - category, it is indicated whether this sensing action frame is a measurement setup request frame or a measurement setup response frame.

[0281] For example, when the value of the sensing sub - category is the first value, it indicates that this sensing action frame is a measurement setup request frame. When the value of the sensing sub - category is the second value, it indicates that this sensing action frame is a measurement setup response frame, where the first value and the second value are different.

[0282] As an example, the first value is 0 and the second value is 3.

[0283] Figure 5 FIG. is a schematic frame format diagram of a measurement setup request frame according to an embodiment of the present application. In this frame format, when the value of the action category field is 4, it indicates that this frame is a public action frame. When the value of the public action sub - category field is 46, it indicates that this frame is a sensing action frame. When the value of the sensing sub - category is 0, it indicates that this frame is a measurement setup request frame.

[0284] In some embodiments, as Figure 5 shown, the measurement setup request frame may further include at least one of the following fields:

[0285] It should be understood that the corresponding relationship between the meanings and values of the following respective fields is only an example. As long as each meaning corresponds to a unique value, the present application is not limited thereto.

[0286] Dialog Token field: Indicates the session identifier corresponding to the target sensing session to be established.

[0287] Sensing parameter field, used to indicate the sensing session parameters that the sensing session initiating device requests to negotiate.

[0288] In the aforementioned case 1, this Dialog Token field can also be used to indicate the Measurement Setup ID.

[0289] Setup Command field: Used to indicate the way to configure sensing session parameters, such as by force or suggestion.

[0290] As an example, when the value is 0, it indicates Demand, and when the value is 1, it indicates Suggest.

[0291] Number of Repetitions: Used to indicate the information about the number of repetitions of the measurement.

[0292] As an example, a value of 0 indicates no maximum number limit (in this case, the measurement can only be explicitly released), and a value of 1 - 255 indicates the maximum number of repetitions (in this case, the measurement can be implicitly released, for example, automatically released after reaching the maximum number of repetitions).

[0293] Another embodiment is that the number of repetitions field can also be replaced by a duration field, used to indicate the duration of the measurement, or the end time of the measurement.

[0294] As an example, a value of 0 indicates that the end time is not set (in this case, the measurement can only be explicitly released), and a value of 1 - 255 indicates the end time in seconds / minutes / hours (in this case, the measurement can be implicitly released, for example, automatically released after reaching the set end time).

[0295] The Figure 5 frame format of the measurement setup request frame in this

[0296] Figure 6 can be applicable to the aforementioned case 1.

[0297] And Figure 5 the difference between the frame format of the measurement setup request frame shown in Figure 6 is that a new Measurement Setup ID field is added to indicate the measurement setup identifier. Therefore, the

[0298] Figure 7 frame format of the measurement setup request frame in this

[0299] In some embodiments, as Figure 7 shown, the measurement setup response frame may further include at least one of the following fields:

[0300] Dialog Token field: Indicates the Measurement Setup ID.

[0301] In the aforementioned Case 1, this Dialog Token field can also be used to indicate the Measurement Setup ID.

[0302] Measurement Information field, used to indicate the sensing session parameters determined by the sensing session response device.

[0303] The Figure 7 frame format of the measurement setup response frame in this can be applicable to the aforementioned Case 1.

[0304] Figure 8 is a schematic frame format diagram of a measurement setup response frame according to another embodiment of the present application. In this frame format, the value of the Action Category field being 4 indicates that this frame is a Public Action frame, the Public Action Sub - category field being 46 indicates that this frame is a sensing action frame, and the Sensing Sub - category value being 3 indicates that this frame is a measurement setup response frame.

[0305] The difference from Figure 7 the frame format of the measurement setup response frame shown is that a new Measurement Setup ID field is added to indicate the measurement setup identification. Therefore, the Figure 8 frame format of the measurement setup response frame in this can be applicable to the aforementioned Case 2 and Case 3.

[0306] Figure 9 is a schematic flowchart of a method 400 for wireless communication according to another embodiment of the present application. This method 400 is a schematic diagram of a method for ending a sensing session.

[0307] As Figure 9 shown, this method 400 includes the following:

[0308] S410, the first device executes a target sensing session ending process according to the type of the target sensing session to be ended, where the first device is a sensing session initiating device or a sensing session response device.

[0309] That is, the sensing session ending process can be initiated by the sensing session initiating device, or alternatively, can be initiated by the sensing session response device.

[0310] In some embodiments, the type of the target sensing session may be of the pairwise negotiation type, or alternatively, may be of the non-pairwise negotiation type, such as the opportunistic type, the monostatic radar type, or the passive type.

[0311] It should be understood that the embodiments of the present application may be applicable to ending a sensing session, or may also be applicable to ending the measurement establishment in a sensing session. Therefore, in some embodiments, S410 may be replaced with:

[0312] The sensing session initiating device executes the target sensing session ending process according to the type of the sensing session corresponding to the measurement to be ended.

[0313] In some embodiments, if the target sensing session is of the non-pairwise negotiation type, the first device releases the target resources corresponding to the target sensing session. For example, it releases all the resources allocated for this target sensing session, such as storage resources or resources for performing measurements, etc.

[0314] In other embodiments, if the target sensing session is of the pairwise negotiation type, the first device releases the target resources corresponding to the target sensing session, and / or the first device sends a second request frame to the second device, where the second request frame is used to request the release of the target resources corresponding to the target sensing session, and the second device is the sensing session response device or the sensing session initiating device.

[0315] In some embodiments, the second request frame may be used to request the release of the target sensing session, or one or more measurement establishments in the target sensing session.

[0316] In some embodiments, the second request frame is also referred to as a measurement teardown request frame or a sensing end request frame.

[0317] In some embodiments, the first device indicates the target sensing session to be ended through a third media access control sublayer management entity service access point (MAC sublayer management entity service access point, MLME-SAP) interface primitive, or executes the target sensing session ending process according to the type of the target sensing session to be ended, such as ending sensing measurements and / or sending the second request frame.

[0318] In some embodiments, the end process of the target sensing session may be based on an indication from the upper-layer application of the first device, or rather, the sensing session end process is triggered by the upper-layer application. For example, when it is necessary to end the target sensing session, the upper-layer application of the first device may call the interface provided by the SME to initiate the sensing session end process. Specifically, the upper-layer application calls the interface provided by the SME, and then the SME calls the third MLME-SAP interface primitive to implement the end of the sensing session.

[0319] In some embodiments, the upper-layer application may refer to an application above the MAC layer, such as a Wi-Fi driver or a wpa_supplicant utility application, etc.

[0320] In some embodiments, the third MLME-SAP interface primitive, or the sensing end request primitive or the measurement end request primitive, is denoted as MLME-SENSTEARDOWN.request.

[0321] In some embodiments, the third MLME-SAP interface primitive is used to indicate at least one of the following:

[0322] The session identifier of the target sensing session, and the measurement setup identifier list corresponding to the measurement to be ended.

[0323] By way of example and not limitation, the third MLME-SAP interface primitive may be expressed as:

[0324] MLME-SENSTEARDOWN.request(

[0325] Dialog Token,

[0326] Number of Setups,

[0327] Measurement Setup ID list,

[0328] VendorSpecificInfo )

[0330] Among them, the Dialog Token field: indicates the identifier of the sensing session to be ended.

[0331] The Number of Setups field: is used to indicate the quantity information of the measurement setup to be ended. For example, a value ranging from 1 to 255 indicates the number of setups to be released. Optionally, a value of 0 indicates releasing the resources of all established measurements.

[0332] Measurement Setup ID list field: Indicates the identifiers of one or more measurement setups to be released.

[0333] VendorSpecificInfo field: Indicates vendor-specific information.

[0334] In some embodiments, after the SME of the first device indicates the information of the target sensing session to be ended to the media access control sublayer management entity (MAC sublayer management entity, MLME) of the first device in the third MLME SAP receive primitive, the MLME may execute the corresponding sensing session end process according to the type of the target sensing session.

[0335] Hereinafter, the specific implementation of the target sensing session end process will be described in combination with the type of the target sensing session.

[0336] Embodiment 1: The type of the target sensing session is a non-paired negotiation type.

[0337] For example, the Opportunistic type, the Monostatic radar type, or the Passive type.

[0338] In this case, the MLME of the first device notifies the MAC sublayer of the first device to release the target resources corresponding to the target sensing session. For example, releasing the storage resources or the resources for measurement allocated for the target sensing session.

[0339] Embodiment 2: The type of the target sensing session is a paired negotiation type.

[0340] In this case, the MLME of the first device notifies the MAC sublayer of the first device to release the target resources corresponding to the target sensing session, and / or the MLME of the first device sends a second request frame to the second device, where the second device is the peer device of the sensing session. For example, when the first device is the initiating device of the sensing session, the second device may be the responding device of the sensing session, and when the first device is the responding device of the sensing session, the second device may be the initiating device of the sensing session.

[0341] In some embodiments, the second request frame includes a session ID and / or a measurement setup ID. Wherein, the session ID may refer to the session ID corresponding to the sensing session to be ended, and the measurement setup ID may refer to the measurement setup ID corresponding to the measurement setup to be ended.

[0342] The resource release method of the first device will be described in detail below in combination with specific scenarios.

[0343] Case 1: The target sensing session corresponds to one measurement establishment, or rather, the session establishment phase of the target sensing session only includes one measurement establishment frame interaction process. There is only one sensing session between the first device and the second device.

[0344] The second request frame carries a measurement establishment identifier or a session identifier. The measurement establishment identifier can be the measurement establishment identifier corresponding to the one measurement establishment in the target sensing session, and the session identifier is the session identifier of the target sensing session.

[0345] In Case 1, the measurement establishment identifier and the session identifier are in one-to-one correspondence, or the measurement establishment identifier and the session identifier are the same.

[0346] In Case 1, the target resources to be released can include the resources corresponding to the one sensing session between the first device and the second device. For example, the storage resources allocated for the sensing session and the resources for measurement.

[0347] That is, when there is only one sensing session between the first device and the second device and the one sensing session only includes one measurement establishment, when the first device ends the one sensing session, it can release all the resources allocated for the sensing session.

[0348] Optionally, in Case 1, the Dialog Token field in the third MLME-SAP interface primitive can also be used to indicate the measurement establishment identifier.

[0349] Case 2: The target sensing session corresponds to multiple measurement establishments, or rather, the session establishment phase of the target sensing session includes multiple measurement establishment frame interaction processes. There is only one sensing session between the first device and the second device.

[0350] Case 2-1: The second request frame carries a session identifier. The session identifier can be the session identifier corresponding to the one sensing session between the first device and the second device.

[0351] In Case 2-1, the target resources to be released can include the resources allocated for the one sensing session between the first device and the second device.

[0352] That is, when there is only one sensing session between the first device and the second device and the one sensing session includes multiple measurement establishments, when the first device ends the one sensing session, it can end all the measurement establishments in the one sensing session. For example, release all the resources allocated for all the measurement establishments in the one sensing session.

[0353] Case 2-2: At least one measurement establishment identifier is carried in the second request frame, excluding the session identifier. The at least one measurement establishment identifier may be the measurement establishment identifier corresponding to the measurement to be ended in the target sensing session.

[0354] In this Case 2-2, the target resources to be released may include the resources allocated for the at least one measurement establishment identifier corresponding to the at least one measurement in the one sensing session between the first device and the second device.

[0355] That is, when there is only one sensing session between the first device and the second device, and the one sensing session includes multiple measurement establishments, the first device may end at least one measurement establishment in the one sensing session. For example, release the resources allocated for the at least one measurement establishment.

[0356] Optionally, in Case 2, the third MLME-SAP interface primitive may not include the Dialog Token field, or the value of the Dialog Token field is a reserved value.

[0357] Case 3: The target sensing session corresponds to multiple measurement establishments, or in other words, the session establishment phase of the target sensing session includes multiple measurement establishment frame interaction processes. There are multiple sensing sessions between the first device and the second device.

[0358] Case 3-1: A session identifier is carried in the second request frame. The session identifier is the session identifier corresponding to the target sensing session to be ended among the multiple sensing sessions between the first device and the second device.

[0359] In this Case 3-1, the target resources to be released may include the resources allocated for the target sensing session between the first device and the second device.

[0360] That is, when there are multiple sensing sessions between the first device and the second device, the first device may end at least one sensing session among the multiple sensing sessions, and then may end all the measurement establishments in the at least one sensing session. For example, release all the resources allocated for the at least one sensing session. The second request frame may be used to instruct the second device to release all the resources allocated for the at least one sensing session.

[0361] Case 3-2: A session identifier and a measurement establishment identifier are carried in the second request frame. The session identifier is the session identifier corresponding to the target sensing session to be ended among the multiple sensing sessions between the first device and the second device, and the measurement establishment identifier is the measurement establishment identifier corresponding to the measurement to be ended in the target sensing session.

[0362] It should be understood that the embodiments of the present application do not limit the number of session identifiers included in the second request frame or the number of measurement establishment identifiers. That is, in the embodiments of the present application, one sensing session end process can end one sensing session, or can end multiple sensing sessions, or can end one measurement establishment, or can end multiple measurement establishments.

[0363] In this case 3-2, the target resources to be released may include the resources allocated for the measurement establishments to be ended in the target sensing session among the multiple sensing sessions between the first device and the second device.

[0364] That is, in the case where there are multiple sensing sessions between the first device and the second device, and each sensing session includes multiple measurement establishments, the first device can end at least one measurement establishment in at least one of the sensing sessions. For example, it can release the resources allocated for at least one measurement establishment in at least one of the sensing sessions.

[0365] It should be understood that in the embodiments of the present application, one measurement establishment frame interaction process may refer to the interaction process of one measurement establishment request frame and one measurement establishment response frame. One measurement establishment frame interaction process can be used to establish one measurement establishment.

[0366] Optionally, when the session establishment phase of one sensing session includes multiple measurement establishment frame interaction processes, releasing one sensing session may include multiple measurement end frame interaction processes.

[0367] After receiving the second request frame, the second device may release the target resources corresponding to the target sensing session according to the second request frame.

[0368] In some embodiments, the method 400 further includes:

[0369] After receiving the second request frame, the MLME of the second device notifies the MAC sublayer of the second device to release the target resources corresponding to the target sensing session, and / or sends fourth indication information to the SME of the second device. The fourth indication information is used to indicate that the second device has received the second request frame sent by the first device.

[0370] In some embodiments, the fourth indication information may also be implemented through the MLME-SAP interface primitive, denoted as MLME-SENSTEARDOWN.indication.

[0371] In some embodiments, MLME-SENSTEARDOWN.indication can be expressed as:

[0372] MLME-SENSTEARDOWN.indication(

[0373] Dialog Token,

[0374] Number of Setups,

[0375] Measurement Setup ID list,

[0376] VendorSpecificInfo

[0377] )。

[0378] Furthermore, the MAC sublayer of the second device may release the target resources corresponding to the target sensing session according to the second request frame.

[0379] Hereinafter, in combination with specific scenarios, the resource release method of the second device will be described in detail.

[0380] Case 1: The target sensing session corresponds to one measurement setup, or in other words, the session establishment phase of the target sensing session only includes one measurement setup frame interaction process. There is only one sensing session between the first device and the second device.

[0381] The second request frame carries a measurement setup identifier or a session identifier. The measurement setup identifier may be the measurement setup identifier corresponding to the one measurement setup in the target sensing session, and the session identifier is the session identifier of the target sensing session.

[0382] In Case 1, the target resources to be released may include the resources corresponding to the one sensing session between the first device and the second device. For example, the storage resources allocated for the sensing session and the resources for measurement.

[0383] That is, when there is only one sensing session between the first device and the second device and the one sensing session only includes one measurement setup, the second device may release all the resources allocated for the sensing session according to the second request frame.

[0384] Case 2: The target sensing session corresponds to multiple measurement setups, or in other words, the session establishment phase of the target sensing session includes multiple measurement setup frame interaction processes. There is only one sensing session between the first device and the second device.

[0385] Case 2-1: The second request frame carries a session identifier. The session identifier may be the session identifier corresponding to the one sensing session between the first device and the second device.

[0386] In this case 2-1, the target resources to be released may include the resources allocated for the one sensing session between the first device and the second device.

[0387] That is, when there is only one sensing session between the first device and the second device, and the one sensing session includes multiple measurement establishments, the second device may end the resources allocated for the one sensing session according to the second request frame.

[0388] Case 2-2: At least one measurement establishment identifier is carried in the second request frame, and the session identifier is not included. The at least one measurement establishment identifier may be the measurement establishment identifier corresponding to the target measurement to be ended in the target sensing session.

[0389] In this case 2-2, the target resources to be released may include the resources allocated for the measurement establishment corresponding to the at least one measurement establishment identifier in the one sensing session between the first device and the second device.

[0390] That is, when there is only one sensing session between the first device and the second device, and the one sensing session includes multiple measurement establishments, the second device may end at least one measurement establishment in the one sensing session according to the second request frame. For example, release the resources allocated for the at least one measurement establishment.

[0391] Case 3: The target sensing session corresponds to multiple measurement establishments, or rather, the session establishment phase of the target sensing session includes multiple measurement establishment frame interaction processes. There are multiple sensing sessions between the first device and the second device.

[0392] Case 3-1: The session identifier is carried in the second request frame. The session identifier is the session identifier corresponding to the target sensing session to be ended among the multiple sensing sessions between the first device and the second device.

[0393] In this case 3-1, the target resources to be released may include the resources allocated for the target sensing session between the first device and the second device.

[0394] That is, in the case of multiple sensing sessions between the first device and the second device, the second device may end the target sensing session among the multiple sensing sessions according to the second request frame. For example, release all the resources allocated for the target sensing session.

[0395] Case 3-2, the session identifier and the measurement establishment identifier are carried in the second request frame. The session identifier is the session identifier corresponding to the target sensing session to be ended among the multiple sensing sessions between the first device and the second device, and the measurement establishment identifier is the measurement establishment identifier corresponding to the measurement establishment to be ended in the target sensing session.

[0396] In this case 3-2, the target resources to be released may include the resources allocated for the measurements to be ended in the target sensing session among the multiple sensing sessions between the first device and the second device.

[0397] That is, when there are multiple sensing sessions between the first device and the second device, and each sensing session includes multiple measurement establishments, the second device ends at least one measurement establishment in the target sensing session according to the second request frame. For example, it releases the resources allocated for at least one measurement establishment in the target sensing session.

[0398] In summary, the first device and the second device have the same way of releasing the target resources of the sensing session, so as to ensure that the resources are effectively released when the sensing session ends. In this way, the released resources can be used for newly established sensing sessions, improving resource utilization.

[0399] In some embodiments of the present application, the first device may also implicitly end the sensing session. For example, when the number of measurements reaches the configured maximum repetition times, the sensing session ends, or when the duration of the measurement reaches the configured duration, the sensing session ends, or when the end time of the measurement reaches the configured end time, the sensing session ends. For example, it ends all the resources corresponding to the sensing session.

[0400] Correspondingly, the second device may also implicitly end the sensing session. For example, when the number of measurements reaches the configured maximum repetition times, the sensing session ends, or when the duration of the measurement reaches the configured duration, the sensing session ends, or when the end time of the measurement reaches the configured end time, the sensing session ends. For example, it ends all the resources corresponding to the sensing session.

[0401] Combined with Figure 10 and Figure 11 , it illustrates the overall process of ending the sensing session in the embodiments of the present application.

[0402] It should be understood that Figure 10 and Figure 11 For the implementation details in each step shown, refer to the specific description of the foregoing embodiments. For the sake of brevity, they will not be elaborated here. Among them, Figure 10 is a schematic interaction diagram of the process of ending the sensing session initiated by the sensing initiating device, Figure 11 is a schematic interaction diagram of the process of ending the sensing session initiated by the sensing session responding device.

[0403] As Figure 10 shown, it may include the following steps:

[0404] S501, when the upper-layer application of the sensing session initiating device confirms the end of the target sensing session, call the interface of the SME of the sensing session initiating device to instruct the SME to end the sensing session.

[0405] S502, the SME of the sensing session initiating device calls the sensing end request primitive to instruct the MLME of the sensing session initiating device to execute the target sensing session end process according to the type of the target sensing session to be ended.

[0406] In some embodiments, if the target sensing session is of the non-paired negotiation type, the MLME of the sensing session initiating device notifies the MAC sublayer of the sensing session initiating device to release the target resources corresponding to the target sensing session. For example, release all resources allocated for the target sensing session, such as storage resources or resources for performing measurements, etc.

[0407] In other embodiments, if the target sensing session is of the paired negotiation type, the MLME of the sensing session initiating device notifies the MAC sublayer of the sensing session initiating device to release the target resources corresponding to the target sensing session, and / or the MLME of the sensing session initiating device sends a measurement end request frame to the sensing session responding device.

[0408] S503, the MLME of the sensing session initiating device sends a measurement end request frame to the MLME of the sensing session responding device.

[0409] S504, after receiving the measurement end request frame, the MLME of the sensing session responding device notifies the SME of the sensing session responding device through the sensing end notification primitive that the sensing session responding device has received the measurement end request frame sent by the sensing session initiating device.

[0410] S505, the SME of the sensing session responding device notifies the upper-layer application of the sensing session responding device.

[0411] As Figure 11 shown, the following steps may be included:

[0412] S601, when the upper-layer application of the sensing session responding device confirms the end of the target sensing session, call the interface of the SME of the sensing session responding device to instruct the SME to end the sensing session.

[0413] S602, the SME of the sensing session responding device calls the sensing end request primitive to instruct the MLME of the sensing session responding device to execute the target sensing session end process according to the type of the target sensing session to be ended.

[0414] In some embodiments, if the target sensing session is of the non-paired negotiation type, the MLME of the sensing session response device notifies the MAC sublayer of the sensing session response device to release the target resources corresponding to the target sensing session. For example, all resources allocated for the target sensing session are released, such as storage resources or resources used for performing measurements, etc.

[0415] In some other embodiments, if the target sensing session is of the paired negotiation type, the MLME of the sensing session response device notifies the MAC sublayer of the sensing session response device to release the target resources corresponding to the target sensing session, and / or the MLME of the sensing session response device sends a measurement end request frame to the sensing session initiating device.

[0416] S603. The MLME of the sensing session response device sends a measurement end request frame to the MLME of the sensing session initiating device.

[0417] S604. After the MLME of the sensing session initiating device receives the measurement end request frame, it notifies the SME of the sensing session initiating device through a sensing end notification primitive that the sensing session initiating device has received the measurement end request frame sent by the sensing session response device.

[0418] S605. The SME of the sensing session initiating device notifies the upper-layer application of the sensing session initiating device.

[0419] Next, the frame format design of the second request frame will be described.

[0420] It should be understood that Figures 12 to 14 The frame format of the exemplified second request frame is only an example, and other frame formats obtained by transforming according to the frame format of the present application example all fall within the protection scope of the present application, and the present application is not limited thereto.

[0421] In some embodiments, the second request frame is implemented by an Action frame or an Action No Ack frame. That is, the measurement end request frame can be implemented by an Action frame or an Action No Ack frame.

[0422] In some embodiments, at least one field in the Action frame or the Action No Ack frame can be used to indicate that the action frame is a measurement end request frame.

[0423] In some embodiments, the Action frame or Action No Ack frame includes an action field, and the action field includes an action category field, a public action subclass field, and a sensing subclass field. The Action frame or Action No Ack frame can be jointly indicated as a measurement end request frame by the values of the action category field, the public action subclass field, and the sensing subclass field.

[0424] As an example, when the value of the action category field is 4, it indicates that the frame is a public action frame. When the public action subclass field is a reserved value (for example, any value within the range of 46 to 255, hereinafter, 46 is used as an example), it indicates that the frame is a sensing action frame. Further, the value of the sensing subclass indicates that the action frame is a measurement end request frame.

[0425] For example, when the value of the sensing subclass is a third value, it indicates that the action frame is a measurement end request frame. As an example, the third value is 2.

[0426] Figure 12 FIG. is a schematic frame format diagram of a measurement end request frame according to an embodiment of the present application. In this frame format, when the value of the action category field is 4, it indicates that the frame is a public action frame. When the public action subclass field is 46, it indicates that the frame is a sensing action frame. When the value of the sensing subclass is 2, it indicates that the frame is a measurement end request frame.

[0427] In some embodiments, as Figure 12 shown, the measurement end request frame may further include at least one of the following fields:

[0428] Dialog Token field: Indicates the session identifier corresponding to the target sensing session to be ended.

[0429] In case 1, this Dialog Token field can also be used to indicate the identifier of the measurement establishment.

[0430] In some scenarios, the Figure 12 frame format of the measurement end request frame in can be applicable to the aforementioned case 1, case 2-1, and case 3-1.

[0431] Figure 13It is a schematic frame format diagram of a measurement end request frame according to another embodiment of the present application. In this frame format, the value of the action category field being 4 indicates that this frame is a Public Action frame, the value of the public action subcategory field being 46 indicates that this frame is a sensing action frame, and the value of the sensing subcategory being 2 indicates that this frame is a measurement end request frame.

[0432] In some embodiments, as Figure 13 shown, the measurement end request frame may further include at least one of the following fields:

[0433] Dialog Token field: Indicates the session identifier corresponding to the target sensing session to be ended.

[0434] Measurement Setup ID field, used to indicate the measurement setup identifier corresponding to the measurement setup to be ended.

[0435] In some scenarios, the Figure 13 frame format of the measurement setup request frame in this case can be applicable to the aforementioned case 2-2 and case 3-2.

[0436] Figure 14 It is a schematic frame format diagram of a measurement end request frame according to yet another embodiment of the present application. In this frame format, the value of the action category field being 4 indicates that this frame is a Public Action frame, the value of the public action subcategory field being 46 indicates that this frame is a sensing action frame, and the value of the sensing subcategory being 2 indicates that this frame is a measurement end request frame.

[0437] In some embodiments, as Figure 14 shown, the measurement end request frame may further include at least one of the following fields:

[0438] Dialog Token field: Indicates the session identifier corresponding to the target sensing session to be ended.

[0439] Number of Setups field: Used to indicate the quantity information of the measurement setups to be ended. For example, a value from 1 to 255 indicates the number of setups to be released. Optionally, a value of 0 indicates releasing the resources of all established measurements.

[0440] Measurement Setup ID list field: Used to indicate the identifiers of one or more measurement setups to be released. Optionally, when the value of the Number of Setups is 0, this Measurement Setup ID list field does not exist.

[0441] In some scenarios, the Figure 14The frame format of the measurement establishment request frame in it can be applicable to the aforementioned Case 2-2 and Case 3-2.
