Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a perception communication method and device. Background Art

[0002] The Institute of Electrical and Electronics Engineers (IEEE) 802.11bf is a new generation of wireless standards that focuses on the perception of passive objects (such as targets that do not carry any equipment). In the 802.11bf standard, Wi-Fi devices can estimate the corresponding parameters (such as speed, distance, angle, etc.) of the target based on the signals they receive and subsequently identify the action / behavior. The 802.11bf standard includes two major categories of standards: low frequency (such as less than 7 GHz (sub7GHz), the implementation method mainly relies on 802.11ac, 802.11ax, 802.11be, 802.11bn and next-generation standards) and high frequency (such as greater than or equal to 60GHz, the implementation method mainly relies on 802.11ad, 802.11ay and next-generation standards).

[0003] When an access point (AP) senses a target in an overlapping basic service set (OBSS), it may be interfered by other devices in the space, such as co-frequency or adjacent frequency interference, and because the sensed target is at the edge of the basic service set (BSS), the perception performance is poor, which will lead to large errors in the measurement results. However, the AP will continue to perform perception measurements in the time window used for perception measurements as long as the communication link is not interrupted. Only after receiving the perception measurement report and performing signal processing through a certain algorithm, the AP can know that there is a large error in the perception measurement result, and can only abandon the measurement result, causing the perception task to fail. Therefore, the AP can request multiple other APs to perform perception measurements on its behalf, such as multiple APs collaborating. When the perception results of one AP are not available, the perception results of other APs can be used.

[0004] How to improve the management flexibility of multiple AP collaboration is a problem that those skilled in the art are currently studying. Summary of the invention

[0138] To facilitate understanding of the technical solution of the present application, the present application will be further described below in conjunction with the accompanying drawings.

[0139] The terms "first" and "second" in the specification, claims and drawings of this application are only used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0140] The "embodiment" mentioned in this article means that the specific features, structures or characteristics described in conjunction with the embodiment can be included in at least one embodiment of the present application.

[0142] The embodiments of the present application provide a perception communication method and device, which can effectively improve the flexibility of managing MAP perception measurement sessions.

[0143] The following introduces the communication system involved in the embodiments of the present application.

[0144] The technical solution provided in the embodiment of the present application can be applied to wireless local area network (WLAN) systems, such as Wi-Fi, etc. The method provided in the embodiment of the present application can be applied to the IEEE 802.11 series of protocols, such as the 802.11be protocol, the 802.11bn protocol, or the next generation of the 802.11bn protocol, etc., which are not listed one by one. The technical solution provided in the embodiment of the present application can also be applied to wireless personal area networks (WPAN) based on ultra-wideband (UWB) technology. The technical solution provided in the embodiment of the present application can also be applied to millimeter wave (MMW) technology, including IMW. The method provided in the embodiment of the present application can be applied to the IEEE802.15 series of protocols, such as the 802.15.4a protocol, the 802.15.4z protocol, or the 802.15.4ab protocol, or a future generation of UWB WPAN protocols, etc., which are not listed one by one. The technical solution provided in the embodiments of the present application can also be applied to the following communication systems, for example, the Internet of Things (IoT) system, the Vehicle to X (V2X), the Narrow Band Internet of Things (NB-IoT) system, the Long Term Evolution (LTE) system, the fifth generation (5G) communication system, and new communication systems emerging in the future communication development.

[0145] WLAN systems can provide high-speed and low-latency transmission. With the continuous evolution of WLAN application scenarios, WLAN systems will be applied to more scenarios or industries, such as the Internet of Things industry, the Internet of Vehicles industry or the banking industry, corporate offices, sports stadiums and exhibition halls, concert halls, hotel rooms, dormitories, wards, classrooms, supermarkets, squares, streets, production workshops and warehouses, etc. Of course, devices that support WLAN communication or perception (such as access points or sites) can be sensor nodes in smart cities (such as smart water meters, smart electricity meters, smart air detection nodes), smart devices in smart homes (such as smart cameras, projectors, display screens, televisions, speakers, refrigerators, washing machines, etc.), nodes in the Internet of Things, entertainment terminals (such as wearable devices such as augmented reality (AR) and virtual reality (VR)), smart devices in smart offices (such as printers, projectors, loudspeakers, speakers, etc.), Internet of Vehicles devices in the Internet of Vehicles, infrastructure in daily life scenarios (such as vending machines, self-service navigation desks in supermarkets, self-service cash registers, self-service ordering machines, etc.), and equipment in large sports and music venues.

[0146] Although the embodiments of the present application mainly take WLAN as an example, especially the network applied to the IEEE 802.11 series of standards. The embodiments of the present application can support Wi-Fi 8, which can also be called ultra-high reliability (UHR) or ultra-high reliability and throughput (UHRT), which are not listed here one by one. The various aspects involved in the embodiments of the present application can be extended to other networks that adopt various standards or protocols. For example, Bluetooth, high performance radio LAN (HIPERLAN) (a wireless standard similar to the IEEE802.11 standard, mainly used in Europe) and wide area network (WAN) or other networks now known or developed later.

[0147] In a possible implementation, the method provided in the embodiment of the present application may be implemented by a communication device in a communication system. For example, the communication device may be an access point (AP) or a station (STA).

[0148] An access point is a device with wireless communication function, supports communication or perception using WLAN protocol, has the function of communicating or perceiving with other devices in the WLAN network (such as non-AP STA or other access points), and of course, can also have the function of communicating or perceiving with other devices. Alternatively, an access point is equivalent to a bridge connecting a wired network and a wireless network, and its main function is to connect various wireless network clients together, and then connect the wireless network to the Ethernet. In a WLAN system, an access point can be called an access point station (AP STA). The device with wireless communication function can be a complete device, or a chip, a processing system or a functional module installed in the complete device, and the device installed with these chips or processing systems or functional modules can implement the method and function of the embodiment of the present application under the control of the chip or processing system or functional module. The AP in the embodiment of the present application is a device that provides services for non-AP STA, and can support 802.11 series protocols or subsequent protocols. For example, an access point can be an access point for a terminal (such as a mobile phone) to enter a wired (or wireless) network, which is mainly deployed in homes, buildings and parks, with a typical coverage radius of tens of meters to hundreds of meters. Of course, it can also be deployed outdoors. For another example, the AP may be a communication entity such as a communication server, a router, a switch, a bridge, etc.; the AP may include various forms of macro base stations, micro base stations, relay stations, etc. Of course, the AP may also be a chip or a processing system or module in the above-mentioned various forms of equipment, so as to realize the method and function of the embodiment of the present application.

[0149] STA is a device with wireless communication function, supports communication or perception using WLAN protocol, and has the ability to communicate or perceive with other non-AP STA or access points in the WLAN network. In the WLAN system, the station can be called a non-access point station (non-AP STA). For example, STA is any user communication device that allows the user to communicate or perceive with the AP and then communicate with the WLAN. The device with wireless communication function can be a complete device, or a chip or processing system or functional module installed in the complete device. The device installed with these chips or processing systems or functional modules can implement the methods and functions of the embodiments of the present application under the control of the chip or processing system or functional module. For example, STA can be a wireless communication chip, a wireless sensor or a wireless communication terminal, etc., and can also be called a user. For another example, STA can be a mobile phone supporting Wi-Fi communication function, a tablet supporting Wi-Fi communication function, a set-top box supporting Wi-Fi communication function, a smart TV supporting Wi-Fi communication function, a smart wearable device supporting Wi-Fi communication function, a vehicle-mounted communication device supporting Wi-Fi communication function, and a computer supporting Wi-Fi communication function. Of course, STA may also be a chip or processing system or module in the above-mentioned various forms of devices, so as to implement the methods and functions of the embodiments of the present application.

[0150] Exemplarily, the communication system to which the method provided in the embodiment of the present application can be applied may include access points and stations. For example, the embodiment of the present application may be applicable to the scenario of communication or perception between AP and STA, between AP and AP, or between STA and STA in WLAN, and the embodiment of the present application is not limited to this. Optionally, the AP may communicate or perceive with a single STA, or the AP may communicate or perceive with multiple STAs at the same time. Specifically, the communication or perception between the AP and multiple STAs can be divided into downlink transmission in which the AP sends signals to multiple STAs at the same time, and uplink transmission in which multiple STAs send signals to the AP. Among them, the WLAN communication protocol can be supported between the AP and the STA, between the AP and the AP, and between the STA and the STA. The communication protocol may include the IEEE802.11 series of protocols, such as 802.11n / 802.11ac / 802.11ax / 802.11be / 802.11bn protocols, and of course, it is also applicable to protocols after 802.11bn.

[0151] Figure 1 1 is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. The communication system may include one or more APs and one or more STAs. Figure 1An access point such as AP1 and three stations such as STA1, STA2 and STA3 are shown in FIG. Figure 1 The communication between AP1 and STA1 shown in FIG. 1 , or the communication between AP1 and STA1, STA2), or the communication between AP and AP (such as Figure 1 ), or, for communication between STAs (such as Figure 1 The method provided in the embodiment of the present application may be applicable to, but not limited to, uplink / downlink transmission of a single user, uplink / downlink transmission of multiple users, vehicle-to-everything (V2X, X can represent anything), device-to-device (D2D). For example, the V2X may include: vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P) or vehicle-to-network (V2N) communication.

[0152] Understandable, Figure 1 The STA is a mobile phone and the AP is a router as an example, which does not limit the types of AP and STA in the embodiments of the present application. Figure 1 Only one AP and three STAs are shown for example, but the number of the APs or STAs may be more or less, which is not limited in the embodiments of the present application.

[0153] Figure 2 Schematic diagram of another communication system provided by an embodiment of the present application. Figure 1 As shown, a BSS may include an AP and one or more STAs associated or unassociated with the AP. The communication system may also include multiple BSSs. Figure 2 Two BSSs are shown as an example, and the two BSSs partially overlap, which is an OBSS. Among them, BSS#1 includes AP#1, STA11, STA12 and STA13, and BSS#2 includes AP#2, STA21, STA22 and STA23. STA11, STA12, STA22, and STA23 are the overlapping parts of the two BSSs. Each BSS consists of an AP and multiple STAs. Within a BSS, data can be transmitted between the AP and each STA. AP#1 and AP#2 can also communicate.

[0154] The following introduces the terms involved in the embodiments of the present application.

[0155] 1. Perception Measurement Session

[0156] A sensing measurement session is a sensing process in which an AP and one or more non-AP STAs associated or unassociated with it participate. For example, an AP can establish a trigger-based (TB) sensing measurement session with one or more STAs as a sensing measurement initiator. After the sensing measurement session is established, the sensing measurement initiator can initiate one or more trigger-based sensing measurement exchanges. For another example, a STA can establish a non-trigger-based (non-TB) sensing measurement session with an AP as a sensing measurement initiator. After the sensing measurement session is established, the sensing measurement initiator can initiate one or more non-TB sensing measurement exchanges. Through sensing measurement interactions, a sensing device (such as an AP or a non-AP STA) can obtain sensing results such as relevant information of a sensing target, such as the speed, angle, or distance of the sensing target.

[0157] The perception measurement initiator may also be referred to as the perception initiator, and the perception measurement responder may also be referred to as the perception responder. The names of the communication devices are not limited in the present embodiment. The specific process of the perception measurement session can refer to the standard and will not be described in detail here.

[0158] 2. Multi-AP (MAP) Awareness Measurement Session

[0159] The MAP perception measurement session is a joint perception process in which multiple APs participate. Each of the multiple APs can perform a perception measurement session with one or more STAs associated or unassociated with each other. When the perception result of one of the multiple APs is not available, the AP can use the perception results of other APs in the multiple APs.

[0160] As an example, a MAP-aware measurement session refers to a MAP-aware measurement session established between multiple APs. In this example, the MAP-aware measurement session may not include a perception measurement session performed between each of the multiple APs and one or more STAs associated or unassociated with each other. For example, the establishment process of a MAP-aware measurement session may include the interaction process of a first request frame and a first response frame as shown below. In this example, frames sent between APs may use a MAP measurement session ID (the MAP measurement session ID may only exist in frames sent between APs), and frames sent between APs and respective STAs use a measurement session ID (the measurement session ID may only exist in frames sent by APs and respective STAs).

[0161] As another example, a MAP-aware measurement session may include not only a MAP-aware measurement session established between multiple APs, but also a MAP-aware measurement session established between each of the multiple APs and one or more STAs associated or unassociated with each other. For example, the process of establishing a MAP-aware measurement session may include not only the interaction process of the first request frame and the first response frame shown below, but also the interaction process of the third request frame and the third response frame shown below. In this example, frames sent between APs may use the MAP measurement session ID, and frames sent between APs and respective STAs may use the measurement session ID+MAP measurement session ID (such as using two fields to carry these two IDs respectively).

[0162] The embodiment of the present application does not limit whether the establishment process of the MAP perception measurement session includes the establishment process of the perception measurement session between the AP and the STA. The relevant description of the termination process of the MAP perception measurement session can also refer to the description of the establishment process of the MAP perception measurement session, which will not be described in detail.

[0163] As an example, the MAP perception measurement initiator can establish a perception measurement session between the perception initiator and its corresponding STA. As another example, the MAP perception measurement initiator may not be a perception initiator, so as not to participate in the perception measurement session. At this time, although the MAP perception measurement initiator does not participate in the perception measurement session, the MAP perception measurement initiator can receive the perception result. Exemplarily, the MAP perception measurement responder can establish a perception measurement session between the perception initiator and its corresponding STA.

[0164] The initiator of a MAP perception measurement session may be referred to as a MAP perception measurement initiator or a MAP perception initiator or a MAP perception initiating AP, etc. The responder of a MAP perception measurement session may be referred to as a MAP perception measurement responder or a MAP perception responder or a MAP perception responding AP, etc. For a MAP perception measurement initiator and a MAP perception measurement responder participating in a perception measurement session, the MAP perception measurement initiator may also be the initiator of the perception measurement session, and the MAP perception measurement responder may also be the initiator of the perception measurement session.

[0165] The MAP awareness measurement session may also be called a joint awareness measurement session, etc. The embodiment of the present application does not limit the name of the MAP awareness measurement session.

[0166] 3.MAP sensing by proxy (SBP) measurement session

[0167] The MAP SBP measurement session is a joint perception process initiated by a certain STA. The certain STA can request a certain AP to initiate a MAP perception measurement session on behalf of the AP, so that the certain AP can initiate the MAP perception measurement session. As to whether the certain AP participates in the MAP perception measurement session, the embodiment of the present application does not limit it. Exemplarily, the certain AP can perform a MAP perception measurement session with one or more other APs.

[0168] As an example, the MAP SBP measurement session may be a measurement session established between the STA and the AP. For example, the establishment process of the MAP SBP measurement session may include the interaction process of the second request frame and the second response frame as shown below.

[0169] As another example, the MAP SBP measurement session may include a measurement session established between the STA and the AP, or a MAP-aware measurement session initiated by the AP. For example, the establishment process of the MAP SBP measurement session may include the interaction process of the second request frame and the second response frame shown below, or may include the interaction process of the first request frame and the first response frame shown below.

[0170] As another example, a MAP SBP measurement session may include a measurement session established between a STA and an AP, a MAP perception measurement session initiated by the AP, and a perception measurement session between each AP participating in the MAP perception measurement session initiated by the AP and one or more STAs associated or unassociated with each other. For example, the process of establishing a MAP SBP measurement session may include an interaction process of a second request frame and a second response frame as shown below, an interaction process of a first request frame and a first response frame as shown below, and an interaction process of a third request frame and a third response frame as shown below.

[0171] The embodiment of the present application does not limit whether the process of establishing a MAP SBP measurement session includes the process of establishing a perception measurement session between an AP and a STA, and whether the process of establishing a MAP SBP measurement session includes the process of establishing a MAP perception measurement session. For the relevant description of the termination process of a MAP SBP measurement session, please refer to the description of the process of establishing a MAP SBP measurement session, which will not be described in detail here.

[0172] As an example, the MAP SBP initiator may act as a perception responder and participate in the perception measurement session corresponding to the MAP SBP process initiated by it. As another example, the MAP SBP initiator may not act as a perception responder and will not participate in the perception measurement session corresponding to the MAP SBP process initiated by it. When the MAP SBP initiator does not act as a perception responder, the MAP SBP initiator may not participate in the perception measurement interaction, but may receive the perception result. As an example, the MAP SBP responder may act as a MAP perception measurement initiator and participate in the MAP perception measurement session. As another example, the MAP SBP responder may not act as a MAP perception measurement initiator and participate in the MAP perception measurement session.

[0173] The initiator of the MAP SBP process may be called a MAP SBP initiator or a MAP SBP measurement session initiator, etc. The responder of the MAP SBP process may be called a MAP SBP responder or a MAP SBP measurement session responder, etc. For a MAP-aware measurement session, the MAP SBP responder may also be a MAP-aware measurement initiator.

[0174] A MAP SBP measurement session may also be referred to as a MAP SBP process or a joint proxy perception process or a joint SBP process, etc. The embodiment of the present application does not limit the name of the MAP SBP measurement session.

[0175] Generally speaking, one awareness application may correspond to one MAP awareness measurement session. Alternatively, one awareness application may correspond to one MAP SBP measurement session.

[0176] For the sake of brevity, the AP and the one or more STAs associated or unassociated with each other shown above are collectively referred to as AP and the one or more STAs corresponding to each other.

[0177] The following describes in detail the process of establishing and terminating a MAP perception measurement session, the process of establishing and terminating a MAP SBP measurement session, the process of establishing and terminating a perception measurement session, and the frame formats involved in each process.

[0178] In some embodiments of the present application, a method for establishing a MAP-aware measurement session is provided.

[0179] Figure 3 FIG. 1 is a schematic diagram of a method for establishing a MAP-aware measurement session provided in an embodiment of the present application. Figure 3 As shown, the method includes:

[0180] 301. A MAP-aware measurement initiator sends a first request frame to a MAP-aware measurement responder, and the MAP-aware measurement responder receives the first request frame. The first request frame includes a MAP measurement session ID, and the MAP measurement session ID is used to identify a MAP-aware measurement session initiated by the MAP-aware measurement initiator.

[0181] The first request frame may be used to request initiation of a MAP-aware measurement session. Alternatively, the first request frame may be used to request establishment of a MAP-aware measurement session.

[0182] As an example, the MAP-aware measurement initiator may be one of the multiple APs participating in the multi-AP collaboration, and the MAP-aware measurement initiator may send a first request frame to the other one or more APs participating in the multi-AP collaboration.

[0183] As another example, the MAP sensing measurement initiator may not be an AP among the multiple APs participating in the multi-AP collaboration. For example, the MAP sensing measurement initiator may be a MAP SBP responder, which may initiate a MAP sensing measurement session, such as sending a first request frame to each of the multiple APs participating in the multi-AP collaboration, but the MAP SBP responder will not participate in the collaboration between the multiple APs.

[0184] Exemplarily, the first AP can act as a MAP perception measurement initiator to send a first request frame to N APs respectively. Each of the above N APs can be called a MAP perception measurement responder. For the same perception application, the MAP measurement session ID in the first request frame sent by the first AP to N different APs is the same. The MAP measurement session ID can identify that the perception measurement session between each AP in the N APs and one or more STAs corresponding to each of them belongs to the same MAP perception measurement session. Thus, the first AP can use the perception result corresponding to the perception measurement session initiated by any AP in the N APs based on the MAP measurement session ID. Whether other contents in the first request frame sent by the first AP to different APs are the same can be determined based on the function of the corresponding field or element in the first request frame. The above N can be a positive integer, or N can be an integer greater than 1. For the convenience of description, the following uses the first AP participating in the MAP perception measurement session as an example to illustrate the method provided in the embodiment of the present application when referring to specific examples.

[0185] Figure 4a FIG. 1 is a flow chart of establishing a MAP-aware measurement session provided in an embodiment of the present application. Figure 4a As shown, AP1, as a MAP awareness measurement initiator, can send a first request frame to AP2.

[0186] As an example, after receiving the first request frame, AP2 may send two STAs corresponding to it (such as Figure 4a As another example, after sending the first response frame, AP2 may establish a perception measurement session between its two corresponding STAs.

[0187] As an example, after receiving the first response frame, AP1 may send two STAs (such as Figure 4a As another example, AP1 may establish a perception measurement session between its two corresponding STAs after sending the first request frame. As another example, AP1 may send a request frame (such as the first request frame) for a MAP perception measurement session to AP2 after establishing the perception measurement session. The embodiments of the present application do not limit the time or order for establishing perception measurement sessions between AP1, AP2 and their respective two STAs.

[0188] By establishing a MAP perception measurement session between AP1 and AP2, AP1 can share the perception result of AP2, or AP1 and AP2 can share the perception result. Figure 4a The illustrated AP1 may be referred to as a first AP, and the AP2 may be referred to as a second AP. The second AP may be an AP among the N APs.

[0189] Figure 4b FIG. 1 is another flow chart of establishing a MAP-aware measurement session provided in an embodiment of the present application. Figure 4b As shown, AP1 as the MAP perception measurement initiator can send a first request frame to AP2 and AP3 respectively. After receiving the first request frame, AP2 and AP3 can reply with a first response frame respectively. For the relevant description of establishing a perception measurement session between AP1, AP2, AP3 and their corresponding STAs, please refer to Figure 4a , which will not be described in detail here. Figure 4b The STA corresponding to AP3 may be STA4.

[0190] As an example, by establishing a MAP perception measurement session between AP1 and AP2, AP1 can share the perception result of AP2. By establishing a MAP perception measurement session between AP1 and AP3, AP1 can share the perception result of AP3. As another example, AP1 establishes MAP perception measurement sessions with AP2 and AP3 respectively, and AP1, AP2, and AP3 can share the perception results. Figure 4b The shown AP1 may be referred to as a first AP, and AP2 and AP3 may be APs among the above-mentioned N APs.

[0191] Figure 4a and Figure 4b The number of STAs corresponding to each AP shown is only an example and should not be construed as a limitation on the embodiments of the present application. Figure 4a and Figure 4b The order in which AP1 sends the perception measurement request frames to its corresponding STA1 and STA2 (such as the sending sequence or sending time, etc.) is only an example. Figure 4a and Figure 4b The order in which AP2 sends the perception measurement request frames to its corresponding STA2 and STA3 is only an example. Figure 4b The order in which AP3 sends the perception measurement request frame to its corresponding STA4 is only an example. Figure 4a and Figure 4b The order in which AP1, AP2, and AP3 send the perception measurement request frames is only an example and should not be construed as limiting the embodiments of the present application. Figure 4b As shown, AP1 and AP2 can also send perception measurement request frames to their corresponding STAs at the same time ( Figure 4b The dotted line portion in FIG. 1 represents that AP2 sends a perception measurement request frame to its corresponding STA). Figure 4a and Figure 4bThe position of the first response frame shown is only an example. For example, AP2 may also reply with a first response frame to AP1 after establishing a perception measurement session with its corresponding STA, and AP3 may also reply with a first response frame to AP1 after establishing a perception measurement session with its corresponding STA.

[0192] Figure 4a The cooperation between two APs is shown exemplarily. Figure 4b The collaboration between three APs is exemplarily shown. In a specific implementation, collaboration between more APs may also be involved, which is not limited in the embodiments of the present application.

[0193] For the sake of simplicity, the following description of specific examples will take the first AP as the MAP perception measurement initiator and the second AP as the MAP perception measurement responder as an example. Exemplarily, one or more different MAP perception measurement sessions can be established between the first AP and the second AP. The embodiment of the present application does not limit the number of MAP perception measurement sessions established between the APs. When the first AP and the second AP establish multiple different MAP perception measurement sessions, the MAP measurement session IDs of the multiple MAP perception measurement sessions can be different.

[0194] The first request frame involved in the embodiment of the present application is introduced in detail below.

[0195] Exemplarily, the first request frame may be referred to as a MAP sensing measurement request frame or a protected MAP sensing measurement request frame or other frames with similar functions / roles. The number of bits (or bytes) and the order of each field in each request frame and response frame given in the drawings of the embodiments of the present application are only examples, and should not limit the frame format or frame length of the request frame and response frame proposed in the embodiments of the present application, or the order of each field. The names of the request frames and response frames and the names of the fields included in the drawings of the embodiments of the present application are only examples, and should not limit the request frames and response frames proposed in the embodiments of the present application. Each frame shown in the drawings of the embodiments of the present application is a format illustration of the action field in the frame.

[0196] Figure 5a : is a schematic diagram of the format of a first request frame provided in an embodiment of the present application. Figure 5aAs shown, the first request frame may include a category, public action / protected dual of public action (or public function / protected dual public function), a dialog token, and a MAP measurement session ID indication. The MAP measurement session ID indication field may be used to carry the MAP measurement session ID. The embodiments of the present application do not limit other contents in the first request frame.

[0197] Further, Figure 5b FIG. 1 is a schematic diagram of another format of a first request frame provided in an embodiment of the present application. Figure 5b As shown, the first request frame may also include at least one of the following items: MAP sensing measurement parameter elements, sensing measurement parameter elements, and availability window elements. The MAP sensing measurement parameter elements in the first request frame may carry relevant parameters for a sensing measurement session corresponding to the MAP sensing measurement session recommended by the MAP sensing measurement initiator to the MAP sensing measurement responder, and the sensing measurement parameter elements in the first request frame may carry sensing parameters for a sensing measurement session corresponding to the MAP sensing measurement session recommended by the MAP sensing measurement initiator to the MAP sensing measurement responder.

[0198] (1) The description of the MAP sensing measurement parameter elements is as follows:

[0199] The MAP perception measurement parameter element may carry the parameters for the perception measurement session between the MAP perception measurement responder and its corresponding perception response end suggested by the MAP perception measurement initiator to the MAP perception measurement responder. For example, the MAP perception measurement parameter element may carry the parameters for the perception measurement session suggested or required by the first AP to the second AP. For the process of the MAP perception measurement session, the second AP is the MAP perception measurement responder. For the process of the perception measurement session, the second AP is the perception measurement initiator.

[0200] For example, Figure 5bAs shown, the MAP sensing measurement parameter element includes at least one of the following: element ID, length, element ID extension, MAP parameters control (MAP parameters control) (also referred to as joint sensing parameter control), sensing responder addresses, and sensing responder IDs. Exemplarily, the MAP parameter control field may include at least one of the following: MAP request (MAP request) (or called joint sensing request), MAP procedure expiry index (MAP procedure expiry exponent) (or called joint sensing procedure expiry index), multi-AP transmission type (MAP transmission model), detection phase type (sounding phase model), number of sensing responders (number of sensing responders), whether the number of sensing responders is required (mandatory number of responders) (mandatory or mandatory), recommended responder list (preferred responder list), recommended number of responders (number of preferred responders), whether the number of recommended responders is required (mandatory preferred responder), sensing responder to sensing responder (sensing responder to sensing responder, SR2SR) detection request (SR2SR sounding request).

[0201] The following is an exemplary description of each field in the MAP parameter control field.

[0202] 1) The MAP request field is used to indicate in which frame the MAP-aware measurement parameter element is carried. Exemplarily, the MAP request field is set to "1" to indicate that the MAP-aware measurement parameter element is carried in the first request frame (e.g., a request frame of a MAP-aware measurement session). The MAP request field is set to "0" to indicate that the MAP-aware measurement parameter element is carried in the first response frame (e.g., a response frame of a MAP-aware measurement session).

[0203] 2) The MAP program expiration index field is used by the MAP sensing measurement responder (such as the second AP) to determine whether to terminate the MAP sensing measurement session. The MAP program expiration index field contains an unsigned integer that can indicate the length of a period of time. Within the time window agreed upon by MAP sensing, the second AP starts counting down the duration indicated by this field after listening to frames in the channel (such as frames related to the MAP sensing measurement session, or frames related to the MAP measurement session ID). When the countdown ends, there is still no frame interaction in the channel, and the second AP considers that the current MAP sensing measurement session process has ended. Exemplarily, the value of this field can be 2. MAP procedure expiry exponent+8 milliseconds. The value of the parameter MAP procedure expiry exponent is equal to the duration indicated by the MAP procedure expiry exponent field.

[0204] 3) The MAP transmission type field indicates the multi-AP collaborative transmission type to support multiple APs to coordinate the transmission of frames (such as control frames or management frames) during the perception measurement process. For example, this field can indicate different transmission types through 2 bits. For example, when the MAP transmission type field is 00, it indicates that the multi-AP collaborative transmission type is coordinated beamforming (CBF), and N APs can send frames in the perception measurement process based on CBF. The embodiments of the present application are not limited to CBF. In the future, a multi-AP collaborative transmission method suitable for the embodiments of the present application can be indicated by other values ​​in the MAP transmission type field.

[0205] 4) The detection phase type field indicates the TB detection phase type established by the MAP sensing measurement responder (such as the second AP). For example, this field can indicate different TB detection phases through 2 bits. For example, when the detection phase type field is 00, the second AP can choose to establish the NDPA detection phase; when the detection phase type field is 01, the second AP can choose to establish the TF detection type; when the detection phase type field is 10, the second AP can choose any one of the NDPA detection phase and the TF detection phase.

[0206] 5) The number of sensing responders field indicates how many sensing responders the MAP sensing measurement responder (such as the second AP) needs to establish a sensing measurement session.

[0207] 6) Whether the number of sensing responders is required field indicates whether the number of sensing responders indicated in the above-mentioned number of sensing responders field is required. Exemplarily, this field can be indicated by 1 bit. When the number of sensing responders is required field is "0", it means that the number of STAs indicated in the number of sensing responders field is not required, and the number of STAs can be regarded as a reference quantity, which can be met as much as possible; on the contrary, the number of sensing responders is required field is "1", indicating that the number of STAs indicated in the number of sensing responders field must meet the requirements.

[0208] 7) The Recommended Response End List field indicates whether to provide a recommended perception response end list for the MAP perception measurement responder (such as the second AP). Exemplarily, the Recommended Response End List field is "1" indicating that a recommended perception response end list is provided for the second AP, and the address information of the recommended perception response end is carried in the MAP perception measurement parameter element in the first request frame (such as carried in Figure 5b The second AP needs to find an STA in the recommended perception responder list to initiate a perception measurement session; the recommended response end list field is "0", indicating that the perception responder is not recommended for the second AP, and the second AP looks for a suitable STA in its own BSS to initiate a perception request.

[0209] 8) The Recommended Response End Number field indicates the number of perception response ends recommended for the MAP perception measurement response end (such as the second AP). For example, if the Recommended Response End Number field is "1", the Recommended Response End Number field indicates how many medium access control (MAC) addresses of the recommended perception response ends are contained in the Perception Response End Address field. If the Recommended Response End Number field is "0", the field is reserved. For example, the characters can be all set to 0, and the second AP does not read the field.

[0210] 9) The field "Whether the number of recommended response terminals is required" indicates whether the perception response terminal recommended for the MAP perception measurement response terminal (such as the second AP) is required. Exemplarily, this field can be indicated by 1 bit. When the field "Whether the number of recommended response terminals is required" is "0", it means that the recommended perception response terminal is not required. The recommended perception response terminal can be regarded as a reference, and the perception response terminal that finally participates in the perception can be found in the recommended perception response terminals as much as possible; on the contrary, the field "Whether the number of recommended response terminals is required" indicates that the perception response terminal that finally participates in the perception must be found in the recommended perception response terminals.

[0211] 10) The SR2SR Probe Request field indicates whether SR2SR awareness needs to be established. For example, if the SR2SR Probe Request field is "0", it means it is not needed, and if the SR2SR Probe Request field is "1", it means it is needed.

[0212] (2) The description of the perception measurement parameter element can be as follows:

[0213] The perception measurement parameter element carries the perception parameters for the perception measurement session recommended by the MAP perception measurement initiator to the MAP perception measurement responder. For example, the perception measurement parameter element may include at least one of the following: bandwidth (BW), maximum (Max) transmit (TX) spatial stream (SS) and maximum receive (RX) SS, maximum transmit space-time stream (STS) and maximum receive STS, number of receive antennas (Number of RX Antennas), number of receive links, number of transmit antennas, number of transmit links. The BW field is used to indicate the perception measurement bandwidth, the maximum TX SS and maximum RX SS fields can be used to indicate the maximum spatial stream, the maximum TX STS and maximum RX STS fields can be used to indicate the maximum space-time stream, and the number of receive antennas field is used to indicate the number of antennas used by the receiving end of the perception PPDU, etc.

[0214] (3) The description of available window elements can be as follows:

[0215] Exemplarily, this element may be used to carry a responding STA (RSTA) available window element. The RSTA available window element is a specific time and period for a MAP awareness measurement session allocated by the MAP awareness measurement initiator to the MAP awareness measurement responder.

[0216] Exemplarily, the first request frame ( Figure 5a and Figure 5b (not shown) may also include a field, which may be used to indicate whether the MAP perception measurement initiator can participate in the perception measurement session as a perception measurement initiator. Exemplarily, this field may be called "whether the MAP perception measurement initiator acts as a perception measurement initiator field", and this field may occupy 1 bit. If this field is set to 1, it indicates that the MAP perception measurement initiator can act as a perception measurement initiator. If this field is set to 0, it indicates that the MAP perception measurement initiator does not act as a perception measurement initiator.

[0217] 302. The MAP-aware measurement responder sends a first response frame to the MAP-aware measurement initiator, and correspondingly, the MAP-aware measurement initiator receives the first response frame. The first response frame may include a MAP measurement session ID.

[0218] The first response frame is used to respond to the first request frame. The MAP measurement session ID in the first response frame is the same as the MAP measurement session ID in the first request frame, and both are used to identify the MAP-aware measurement session initiated by the MAP-aware measurement initiator (such as the first AP). Exemplarily, the first AP can effectively know that the first response frame is a response to the first request frame based on the MAP measurement session ID in the first response frame, and thus can know the reply content of the second AP to the first request frame.

[0219] The first response frame involved in the embodiment of the present application is introduced in detail below.

[0220] The first response frame may be referred to as a MAP sensing measurement response frame or a protected MAP sensing measurement response frame or other frames having similar functions / roles. For ease of description, the following examples are taken as examples in which the first request frame is a MAP sensing measurement request frame and the first response frame is a MAP sensing measurement response frame.

[0221] Figure 5c : is a schematic diagram of the format of a first response frame provided in an embodiment of the present application. Figure 5c As shown, the first response frame may include a MAP-aware measurement identifier indication field. For relevant descriptions of the MAP-aware measurement session identifier indication field, please refer to Figure 5a , which will not be described in detail here.

[0222] Furthermore, if Figure 5cAs shown, the first response frame may also include a status code field, which may indicate the response result of the MAP-aware measurement responder (such as the second AP). Exemplarily, the status code field may indicate at least one of the following: success, rejected_with_suggested_changes, and request_declined. Exemplarily, "success" indicates that the MAP-aware measurement responder (such as the second AP) agrees to establish the MAP-aware measurement session requested by the first request frame. "Request rejection" indicates that the second AP does not agree to establish the MAP-aware measurement session requested by the first request frame. "Reject and provide suggested changes" indicates that the second AP does not agree to establish the MAP-aware measurement session, but the second AP may provide some suggested parameters to the first AP, and the first AP may re-initiate a request frame for the MAP-aware measurement session based on the parameters suggested by the second AP. If the status code field indicates "reject and provide suggested changes", the first response frame may also include a MAP-aware measurement parameter element and / or a perception measurement parameter element, which may be used to carry the suggested parameters provided by the second AP to the first AP. For example, the MAP perception measurement parameter element and the perception measurement parameter element may be related parameters when the second AP recommends the first AP to establish a perception measurement session corresponding to the MAP perception measurement session. For a detailed description of these two elements, please refer to Figure 5b , which will not be described in detail here.

[0223] Furthermore, if Figure 5c As shown, the first response frame may also include a decline duration indication field, which may include a decline duration field, which may be used by the MAP-aware measurement responder (such as the second AP) to indicate to the MAP-aware measurement initiator (the first AP) not to initiate a MAP-aware measurement session (or not to send a request frame for a MAP-aware measurement session) within the duration indicated by the decline duration field. Alternatively, the decline duration field may be used by the MAP-aware measurement responder (such as the second AP) to indicate to the MAP-aware measurement initiator (such as the first AP) that the MAP-aware measurement responder does not want to receive a request frame for a MAP-aware measurement session within the duration indicated by the decline duration field. If the status code field indicates "request rejection", the first response frame may include a decline duration indication field, which may indicate how long the second AP requires the first AP not to send the first request frame again after the first request frame is rejected.

[0224] Exemplarily, after receiving the first response frame, the first AP may learn from the MAP measurement session ID indication field in the first response frame that the first response frame is a response frame for the first request frame, and may learn from the status code field in the first response frame the response result of the second AP. As an example, when the status code field indicates "success", the first AP and the second AP may establish a MAP awareness measurement session according to the content in the first request frame. The second AP may establish an awareness measurement session with its corresponding STA according to the content suggested by the first request frame. As another example, when the status code field indicates "request rejection", the first AP may learn based on the rejection duration indication field that the second AP does not want to receive the first request frame again within the duration indicated by the field. After the duration indicated by the field, the first AP may send the first request frame to the second AP again. As another example, when the status code field indicates "reject and provide suggested modifications", the first AP may re-initiate a request frame for the MAP awareness measurement session according to the parameters suggested by the second AP in the first response frame (such as the relevant content in the first request frame re-sent by the first AP may be determined based on the relevant parameters in the first response frame).

[0225] In the embodiment of the present application, the first request frame sent by the MAP-aware measurement initiator to the MAP-aware measurement responder carries the MAP measurement session ID, so that the APs participating in the multi-AP collaboration can effectively identify the MAP-aware measurement session based on the MAP measurement session ID, so that different MAP measurement session IDs represent different MAP-aware measurement sessions, effectively improving the flexibility of managing the MAP-aware measurement session. Exemplarily, the MAP-aware measurement initiator allocates MAP measurement session IDs to different MAP-aware measurement sessions, so that each AP participating in the MAP-aware measurement session can know which perception measurement sessions correspond to the same MAP-aware measurement session based on the MAP measurement session ID. Exemplarily, the MAP-aware measurement initiator allocates MAP measurement session IDs to different MAP-aware measurement sessions, so that when the MAP-aware measurement initiator or the MAP-aware measurement responder needs to terminate a certain MAP-aware measurement session, the MAP measurement session ID can be effectively identified.

[0226] In some other embodiments of the present application, a method for terminating a MAP awareness measurement session is provided.

[0227] For details about the first AP and the second AP involved in this method, please refer to Figure 3 The method for terminating a MAP awareness measurement session is as follows:

[0228] As a possible scenario, after the MAP perception measurement session is established, each AP can perform perception measurement with its corresponding STA. When there is no need to continue the perception measurement, the MAP perception measurement session can be terminated. The MAP perception measurement initiator or the MAP perception measurement responder can initiate a termination frame. For example, the first AP can send a termination frame. For another example, the second AP can send a termination frame.

[0229] by Figure 4b Taking the process shown as an example, as an example, Figure 6a As shown in the termination frame of the solid line portion, AP1 can send a termination frame to AP2 to terminate one or more MAP awareness measurement sessions between AP1 and AP2. As another example, Figure 6a As shown in the termination frames of the solid line part and the dotted line part, AP1 can send termination frames to AP2 and AP3 respectively. AP1 can terminate one or more MAP-aware measurement sessions between AP1 and AP2 and one or more MAP-aware measurement sessions between AP1 and AP3 respectively through the termination frames. Here, the termination frame initiated by AP1 is used as an example. In a specific implementation, the termination frame can also be initiated by AP2 or AP3, which is not shown here one by one. For a specific description of the termination frame, please refer to the following Figure 7a and Figure 7b , which will not be elaborated here.

[0230] As another possible scenario, during the MAP perception session establishment phase, the MAP perception measurement responder receives the first request frame and may agree (such as setting the status code field in the first response frame to "success") to the first request frame of the MAP perception measurement initiator based on the information of the MAP perception measurement responder at that time (such as the information when replying to the first response frame). Then, during the process of establishing a perception measurement session with its corresponding STA, the MAP perception measurement responder finds that the perception measurement session cannot be established as required by the first request frame. At this time, the MAP perception measurement responder can terminate the MAP perception measurement session that has been agreed to by the MAP perception measurement initiator by sending a termination frame. In this scenario, the termination frame can be sent by the MAP perception measurement responder. For example, the second AP sends a termination frame to other APs participating in the collaboration (such as the first AP).

[0231] by Figure 4b Taking the process shown as an example, as an example, Figure 6bAs shown in the termination frame of the solid line part, AP1 can send a termination frame to AP2, and terminate one or more MAP perception measurement sessions between AP1 and AP2 through the termination frame. Since the MAP perception measurement session between AP1 and AP2 is terminated, the MAP perception measurement session between AP1 and AP3 continues to be executed, and AP1 can share the perception result of AP3, or AP1 and AP3 can share the perception result. When AP2 and AP3 also establish a MAP perception measurement session initiated by AP1, the MAP perception measurement session between AP2 and AP3 will also continue to be executed, and AP2 or AP3 can share the perception result of each other, or AP3 and AP2 can share the perception result. As another example, Figure 6b As shown in the termination frames of the solid and dotted parts, AP1 can send termination frames to AP2 and AP3 respectively, and terminate the MAP perception measurement session between AP1 and AP2, and the MAP perception measurement session between AP1 and AP3 through the termination frames. When AP2 and AP3 also establish a MAP perception measurement session initiated by AP1, the MAP perception measurement session between AP2 and AP3 continues to execute, and AP2 or AP3 can share each other's perception results, or AP3 and AP2 can share perception results. Here, AP1 initiates the termination frame as an example. In the specific implementation, the termination frame can also be initiated by AP2 or AP3, which is not shown here one by one. For a specific description of the termination frame, please refer to the following Figure 7a and Figure 7b , which will not be elaborated here.

[0232] The termination of the MAP-aware measurement session shown in the embodiment of the present application may also be referred to as closing the MAP-aware measurement session. The termination frame may also be referred to as a MAP-aware measurement session termination frame or a MAP-aware measurement session closing frame or a protected MAP-aware measurement session termination frame or other frames with similar functions / roles, which are not listed here one by one.

[0233] Figure 7a This is a format diagram of a termination frame provided in an embodiment of the present application. The termination frame may include at least one of the following: category, public action / protected dual public action, and MAP measurement session identification indication. The MAP-aware session identification indication field can be used to identify a MAP-aware measurement session. The receiving end of the termination frame can terminate the MAP-aware measurement session indicated by the MAP-aware session identification indication field through the MAP-aware session ID indication field. For relevant descriptions of the MAP measurement session ID indication field, please refer to Figure 5a and Figure 5b etc., which will not be described in detail here.

[0234] for Figure 7aFor the termination frame shown, the termination frame can be used to terminate the MAP-aware measurement session indicated by the MAP measurement session ID indication field between the two communicating parties. The termination frame may include one or more MAP measurement session ID indication fields, each of which can be used to identify a MAP-aware measurement session. Figure 7a A MAP measurement session ID indication field is shown exemplarily, which should not be understood as a limitation on the embodiments of the present application. The two communicating parties shown in the embodiments of the present application may be an AP that sends a termination frame and an AP that receives a termination frame. For example, the two communicating parties may be a MAP-aware measurement initiator and a MAP-aware measurement responder, or the two communicating parties may be two MAP-aware measurement responders.

[0235] In the embodiment of the present application, the termination frame indicates the terminated MAP-aware measurement session by including one or more MAP measurement session ID indication fields, so that the AP receiving the termination frame can clearly know which MAP-aware measurement sessions need to be terminated between it and the AP that sends the termination frame, thereby providing higher flexibility in indicating the termination of the MAP-aware measurement session.

[0236] Furthermore, if Figure 7b As shown, the termination frame may also include a MAP measurement session termination control (MAP measurementsessionterminationcontrol). Exemplarily, the MAP measurement session termination control field may include at least one of the following: termination of all MAP measurement sessions (terminationall MAP measurementsession), MAP measurement session error status (MAP measurementsessionerrorstatus).

[0237] The following is an explanation of the MAP measurement session termination control field:

[0238] (1) Terminate All MAP Measurement Sessions The field may indicate whether to terminate all MAP awareness measurement sessions between the communicating parties.

[0239] As an example, the value of the Terminate All MAP Measurement Sessions field as the first value may indicate the termination of all MAP awareness measurement sessions between the AP that sends the termination frame and the AP that receives the termination frame. In this case, the MAP measurement session ID indication field may be set to reserved. The above-mentioned all awareness measurement sessions include both established MAP awareness measurement sessions and MAP awareness measurement sessions that have not yet been established. Figure 6aTaking the termination frame sent by AP1 to AP2 as an example, when the value of the "Terminate All MAP Measurement Sessions" field in the termination frame is the first value, it can indicate that all MAP awareness measurement sessions established between AP1 and AP2 are terminated. Figure 6b Taking the termination frame sent by AP2 to AP1 as an example, when the value of the Terminate All MAP Measurement Sessions field in the termination frame is the first value, it can indicate that AP2 has agreed to terminate the MAP awareness measurement session established by AP1 but has not yet completed.

[0240] As another example, the value of the Terminate All MAP Measurement Sessions field being the second value may indicate terminating the MAP-aware measurement session identified by the MAP Measurement Session ID Indication field between the two communicating parties. Figure 6a Taking the termination frame sent by AP1 to AP2 as an example, when the value of the Terminate All MAP Measurement Sessions field in the termination frame is the second value, it can indicate the termination of the MAP awareness measurement session identified by the MAP Measurement Session ID Indication field between AP1 and AP2. Figure 6b Taking the termination frame sent by AP2 to AP1 as an example, when the value of the Terminate All MAP Measurement Sessions field in the termination frame is the second value, it can indicate that AP2 has agreed to terminate the MAP awareness measurement session identified by the MAP Measurement Session ID Indication field that AP1 has agreed to establish but has not yet completed.

[0241] Exemplarily, the above-mentioned Terminate All MAP Measurement Sessions field may occupy 1 bit. For example, the above-mentioned first value may be 1, and the second value may be 0. Of course, the Terminate All MAP Measurement Sessions field may also occupy more bits, which are not listed here one by one.

[0242] (2) The MAP measurement session error status field can be used to indicate the reason for terminating the MAP perception measurement session. For example, when the MAP measurement session error status field is 1, it can indicate that the reason for terminating the MAP perception measurement session is that the corresponding perception measurement session cannot be established as required. At this time, the termination frame can carry the MAP perception measurement parameter element (such as Figure 7b As shown), the perception measurement parameter elements ( Figure 7b At least one of the following elements is not shown). Exemplarily, the AP that sends the termination frame can indicate the recommended parameters to the AP that receives the termination frame through these two elements, so that when the AP that receives the termination frame (such as the MAP perception measurement initiator) needs to initiate a MAP perception measurement session again, the AP that receives the termination frame can initiate a MAP perception measurement session based on the parameters recommended by the AP that sends the termination frame. For relevant descriptions of the MAP perception measurement parameter element and the perception measurement parameter element, please refer to Figure 5bEtc., which will not be described in detail here. Exemplarily, when the value of the Terminate All MAP Measurement Sessions field is the first value, the value of the MAP Measurement Session Error Status field may be 0. The value of the MAP Measurement Session Error Status field is 0, and the AP that sends the termination frame may be a MAP perception measurement initiator or a MAP perception measurement responder.

[0243] In the embodiment of the present application, the MAP measurement session termination control field and the MAP measurement session ID indication field are used to indicate the termination of one MAP awareness measurement session or all MAP awareness measurement sessions between two communicating parties, which can effectively save signaling overhead.

[0244] Combined with the above Figure 7a One or more MAP measurement session ID indication fields are shown, and Figure 7b The MAP measurement session termination control field shown in the figure, the termination frame may also include one or more MAP measurement session ID indication fields and a MAP measurement session termination control field. At this time, the termination frame can terminate one MAP awareness measurement session or multiple MAP awareness measurement sessions or all MAP awareness measurement sessions between the two communicating parties. For this implementation, please refer to Figure 7a and Figure 7b The relevant descriptions will not be described in detail here.

[0245] Take AP1 sending a termination frame to AP2 as an example. Figure 6c This is a flowchart of a MAP-aware measurement session termination process provided by an embodiment of the present application. Figure 6c For the description of each AP and STA in Figure 4a , which will not be described in detail here.

[0246] like Figure 6c As shown, AP1 sends a termination frame to AP2. After receiving the termination frame, AP2 can parse the termination frame. Exemplarily, by parsing the MAP measurement session termination control field and the MAP measurement session ID indication field in the termination frame, AP2 can learn that AP2 needs to terminate a certain MAP-aware measurement session between it and AP1 (such as the MAP-aware measurement session identified by the MAP measurement session ID field), or terminate all MAP-aware measurement sessions between it and AP1. When AP1 also needs to terminate the MAP-aware measurement session between AP1 and other collaborative APs, AP1 can also send a termination frame to other collaborative APs.

[0247] Exemplarily, after sending the termination frame, AP1 may terminate the perception measurement session between the STA corresponding to it. After parsing the termination frame, AP2 may terminate the perception measurement session between the STA corresponding to it. Figure 6cThe order in which AP1 and AP2 send the perception measurement session termination frame is only an example and should not be understood as a limitation to the embodiments of the present application.

[0248] In the embodiment of the present application, the AP sending the termination frame can explicitly instruct the AP receiving the termination frame to terminate a certain MAP awareness measurement session or all MAP awareness measurement sessions between the communicating parties through the termination frame, thereby effectively improving the termination process of the MAP awareness measurement session.

[0249] In some other embodiments of the present application, a method for establishing a multi-AP sensing by proxy (MAP SBP) process is provided.

[0250] For details about the first AP and the second AP involved in this method, please refer to Figure 3 , which will not be described in detail here. The method of establishing the MAP SBP process is as follows:

[0251] Figure 8 FIG. 1 is a schematic diagram of a method for establishing a MAP SBP process provided in an embodiment of the present application. Figure 8 As shown, the method includes:

[0252] 801. A MAP SBP initiator sends a second request frame to a MAP SBP responder, and correspondingly, the MAP SBP responder receives the second request frame. The second request frame is used to request the MAP SBP responder to initiate a MAP awareness measurement session.

[0253] Since the MAP SBP initiator requests the MAP SBP responder to initiate a MAP-aware measurement session through the second request frame, when the MAP SBP responder participates in the MAP-aware measurement session, the MAP SBP responder can also be the MAP-aware measurement initiator. Fig. 9As shown, STA4, as a MAP SBP initiator, can send a second request frame to AP1 to request the AP1 to initiate a MAP-aware measurement session. AP1, as a MAP SBP responder, can reply a second response frame to the STA4 after receiving the second request frame (such as step 802 below). Exemplarily, AP1 can serve as the initiator of a MAP-aware measurement session and initiate a MAP-aware measurement process. In a specific implementation, STA4, as a MAP SBP initiator, can also send a second request frame to AP2 to request the AP2 to initiate a MAP-aware measurement session. AP2, as a MAP SBP responder, can reply a second response frame to the STA4 after receiving the second request frame. Since STA4 sends the second request frame to AP1 and AP2 respectively, the MAP SBP process initiated by STA4 to AP1 and the MAP SBP process initiated by STA4 to AP2 can be considered as different MAP SBP processes. For the convenience of description, when referring to specific examples below, the example of STA4 sending the second request frame to AP1 is used for explanation.

[0254] The specific manner in which AP1 (or AP2) initiates the MAP sensing measurement process is not limited in the present embodiment. For example, the specific manner in which AP1 (or AP2) initiates the MAP sensing measurement process can be referred to Figure 3 The relevant instructions will not be elaborated here. Fig. 9 For other explanations, please refer to the above Figure 4a etc., which will not be described in detail here.

[0255] Exemplarily, the second request frame may be called a MAP SBP request (MAP SBP request) frame or other frames having similar functions / roles.

[0256] Fig.10a : is a schematic diagram of the format of a second request frame provided in an embodiment of the present application. Fig.10aAs shown, the second request frame may include a category, a public action / protected dual public action (or public function / protected dual public function), and a dialog token. Further, the second request frame may also include at least one of the following: a MAP SBP parameter element, a MAP sensing measurement parameter element, a sensing measurement parameter element, and an initiating STA (ISTA) available window element. The MAP SBP parameter element in the second request frame may carry relevant parameters of a MAP sensing measurement session corresponding to a MAP SBP process initiated by a MAP sensing measurement initiator as suggested by a MAP SBP initiator. For example, the MAP SBP parameter element may be used to carry the number of APs participating in a MAP sensing measurement session, an AP address, an AP identifier, and the like. The MAP sensing measurement parameter element in the second request frame may carry relevant parameters for a sensing measurement session (a sensing measurement session corresponding to a MAP sensing measurement session corresponding to a MAP SBP process) suggested by a MAP sensing measurement initiator as suggested by a MAP SBP initiator. The perception measurement parameter element may carry the perception parameters for the perception measurement session suggested by the MAP SBP initiator and which the MAP perception measurement initiator may suggest to the MAP perception measurement responder.

[0257] (1) The ISTA available window element is used by the MAP SBP initiator to inform the MAP SBP responder of the idle time period during which the MAP SBP responder can allocate the time and cycle of the MAP SBP.

[0258] (2) For the relevant description of the MAP sensing measurement parameter element, please refer to the first request frame. Figure 5b The relevant description of is not repeated here. Fig. 9 For example, the MAP perception measurement parameter element can be used to carry relevant parameters of the perception measurement session corresponding to the MAP perception measurement session recommended or required by the MAP SBP initiator to the MAP SBP responder, such as how many perception responders are required to participate in establishing the perception measurement session by AP2 participating in the MAP perception measurement session.

[0259] (3) For the relevant description of the perception measurement parameter element, please refer to the relevant description in the first request frame, which will not be repeated here.

[0260] (4) The description of MAP SBP parameter elements is as follows:

[0261] The MAP SBP parameter element can carry the relevant parameters that the MAP SBP initiator sends to the MAP SBP responder. For example, the MAP SBP parameter element can carry the relevant parameters that STA4 needs to inform AP1. For example, Fig.10b FIG. 1 is a schematic diagram of the format of a MAP SBP parameter element provided in an embodiment of the present application. Fig.10b As shown, the MAP SBP parameter element may include at least one of the following: element ID, length, element ID extension, MAP SBP parameter control, AP address, and AP ID.

[0262] 1) The element identification field and the element identification extension field can jointly indicate the type and usage scenario of the corresponding element (such as the MAP SBP parameter element). For example, the element identification extension field can be used to indicate that the MAP SBP parameter element carries the relevant parameters of the MAP SBP process. The specific values ​​of the element identification field and the element identification extension field of the MAP SBP parameter element are not limited in the embodiments of the present application.

[0263] 2) The contents of the MAP SBP parameter control field can be found in Fig.10b .like Fig.10b As shown, the MAP SBP parameter control field may include at least one of the following: MAP SBP request (or called joint SBP request, Co-SBP request), MAP SBP procedure expiry exponent, whether the MAP SBP initiator acts as a perception measurement responder, number of APs, whether the number of APs is mandatory, preferred AP list, whether the recommended AP list is mandatory ( Fig.10b not shown), number of preferred APs, different sensing elements of preferred APs (not shown), Fig.10b Not shown), whether the recommended AP quantity is necessary, whether the MAP SBP responder is used as the MAP perception measurement initiator ( Fig.10bThe above fields are described below by way of example.

[0264] a) The MAP SBP request field can be used to indicate in which frame the MAP SBP parameter element is carried. Exemplarily, the MAP SBP request field is set to "1" to indicate that the MAP SBP parameter element is carried in the request frame (such as the second request frame) of the MAP SBP initiated by the STA (such as STA4). The MAP SBP request field is set to "0" to indicate that the MAP SBP parameter element is carried in the response frame (such as the second response frame) of the MAP SBP initiated by the STA. Generally speaking, the type field or the public action / protected dual public action field in the second request frame can also indicate that the second request frame is a request frame for the MAP SBP process initiated by the STA, so the MAP SBP request field can be an optional field.

[0265] b) The MAP SBP program expiration index field is used by the MAP SBP responder to determine whether to terminate the MAP SBP process. For example, when the MAP SBP process is established, the timer starts counting. If there is a new frame interaction between STA4 and AP1 in the MAP SBP process, the timer is refreshed. If not, the timer keeps counting. When the timer ends, the MAP SBP process ends.

[0266] c) Whether the MAP SBP initiator acts as a perception measurement responder field indicates whether the MAP SBP initiator acts as a perception measurement responder to participate in the perception measurement session. For example, if the MAP SBP initiator acts as a perception measurement responder field is "0", it means that STA4 is not required to participate in the perception measurement session, and if the MAP SBP initiator acts as a perception measurement responder field is "1", it means that STA4 is required to participate in the MAP perception measurement session.

[0267] d) The AP number field indicates how many APs need to be included in the process of the MAP awareness measurement session. For example, STA4 can use the AP number field to indicate how many APs the MAP awareness measurement initiator (such as AP1) needs to establish a MAP awareness measurement session.

[0268] e) The AP Quantity Required field indicates whether the number of APs indicated in the AP Quantity field is mandatory. For example, when the AP Quantity Required field is "0", it means that the number of APs indicated in the AP Quantity field is not mandatory. At this time, the number of APs indicated in the AP Quantity field is a reference quantity and should be met as much as possible. The AP Quantity Required field is "1" to indicate that the number of APs indicated in the AP Quantity field is mandatory.

[0269] f) The recommended AP list field indicates whether a recommended AP list is provided for the MAP SBP responder. Exemplarily, a "1" in the recommended AP list field indicates that a recommended AP list is provided for the MAP SBP responder, and at least one of the recommended AP address field and the AP identification field is carried in the MAP SBP parameter element in the second request frame. The MAP SBP responder needs to find an AP in the recommended AP list to initiate a request frame for a MAP-aware measurement session (such as the first request frame shown above). A "0" in the recommended AP list field indicates that an AP list is not recommended for the MAP SBP responder. The MAP SBP responder searches for a suitable AP among all APs participating in multi-AP collaboration to initiate a request frame for a MAP-aware measurement session. Exemplarily, the number of AP address fields may be the same as the number of APs in the recommended AP list field. Exemplarily, the number of AP identification fields may be the same as the number of APs in the recommended AP list field. Fig.10b The AP address field shown can be used to carry the MAC address of the recommended AP. Fig.10b The AP identification field shown may be used to carry the ID of the recommended AP or the AID or BSSID of the recommended AP; or other identification information for identifying the AP, etc., which is not limited in the embodiments of the present application. Exemplarily, when the MAP SBP responder does not serve as the MAP perception measurement initiator, the MAP perception measurement initiator may be based on the predetermined AP address field in the second request frame (such as Fig.10b The first AP address field shown in FIG. 1 is determined, or based on a predetermined AP identification field in the second request frame (such as Fig.10b The embodiment of the present application does not limit how to indicate the MAP awareness measurement initiator.

[0270] g) The Recommended AP Quantity field indicates the number of recommended APs provided to the MAP SBP responder. If the Recommended AP Quantity field is "1", the Recommended AP Quantity field indicates how many MAP Awareness Measurement Parameter elements the MAP SBP Parameter Element field contains, where each MAP Awareness Measurement Parameter element may correspond to one recommended AP. If the Recommended AP Quantity field is "0", the field is reserved.

[0271] h) Whether the recommended AP number is mandatory field indicates whether the recommended AP number indicated in the above-mentioned recommended AP number field is mandatory.

[0272] i) The Different Perception Element Field of Recommended AP indicates whether to provide different perception parameters for the recommended AP (such as Fig.10aMAP perception measurement parameter element shown). The different perception element field of the recommended AP may be meaningful when the recommended AP list is "1". Exemplarily, the different perception element field of the recommended AP is "1" indicating that different parameters are assigned to the recommended APs; the different perception element field of the recommended AP is "0" indicating that the recommended APs use the same parameters, and the second request frame includes a MAP perception measurement parameter element. If the different perception element field of the recommended AP is "0", when the MAP SBP responder needs to send a first request frame to A2 in the recommended AP, the MAP SBP responder may generate a first request frame based on the information obtained in the second request frame. Exemplarily, the frame structure of the first request frame is as follows: Figure 5b As shown, then, the relevant information in the MAP parameter control field in the MAP aware measurement parameter element of the first request frame can be determined by the second request frame.

[0273] 802. The MAP SBP responder sends a second response frame to the MAP SBP initiator, and correspondingly, the MAP SBP initiator receives the second response frame. The second response frame includes a MAP measurement session ID.

[0274] The second response frame is used to respond to the second request frame. The MAP measurement session ID in the second response frame may be the same as the MAP measurement session ID in the first request frame. For example, the MAP SBP responder may initiate a MAP-aware measurement session as a MAP-aware measurement initiator, and the identifier of the MAP-aware measurement session is the same as the identifier carried by the MAP measurement session ID indication field in the second response frame it replies to the MAP SBP initiator.

[0275] Exemplarily, the second response frame may be called a MAP SBP response (MAP SBP response) frame or other frames having similar functions / roles.

[0276] Fig.10c : is a schematic diagram of the format of a second response frame provided in an embodiment of the present application. Fig.10cAs shown, the second response frame may include at least one of the following: category, public action / protected dual of public action, dialog token, status code, MAP measurement session ID indication, associated ID / unassociated STAID (AID / USID). Further, the second response frame may also include at least one of the following: MAP SBP parameter element, MAP perception measurement parameter element, ISTA available window element, rejection duration indication ( Fig.10c (not shown). The frame structure of the second response frame is substantially the same as that of the second request frame. The fields carrying different information in the second response frame and the second request frame are described in detail below.

[0277] (1) The type field or the public action / protected dual public action field may indicate that the second response frame is a response frame for responding to the MAP SBP process initiated by the MAP SBP initiator. The specific values ​​of the type field and the public action / protected dual public action field are not limited in the embodiments of the present application.

[0278] (2) The status code field may indicate whether the MAP SBP responder accepts the request of the second request frame. For example, the status code field may include at least one of the following fields: success, rejection and provision of suggested modifications, and request rejection. Exemplarily, in the case where the status code field carries the rejection and provision of suggested modifications field, the second response frame also includes at least one of the following: a MAP SBP parameter element, a MAP perception measurement parameter element, and at least one of the perception measurement parameter elements. For relevant descriptions of the status code field, please refer to the description of the status code in the above-mentioned first response frame, which will not be described in detail here.

[0279] (3) The MAP measurement session ID indication field can identify the MAP perception measurement session. For details about the MAP measurement session ID indication field, refer to Figure 5a etc., which will not be described in detail here.

[0280] (4) If the MAP SBP initiator (such as STA4) is associated with the MAP SBP responder (such as AP1), the AID / USID field can carry the AID of the MAP SBP initiator. If the MAP SBP initiator is not associated with the MAP SBP responder, the AID / UDIS field can carry the USID of the MAP SBP initiator. For example, the USID can be allocated to the MAP SBP initiator by the MAP SBP responder.

[0281] If the Status Code field is "Success" and the MAP SBP initiator is associated with the MAP SBP responder, the AID / USID field can be set to the AID of the MAP SBP initiator. If the Status Code field is "Success" and the MAP SBP initiator is not associated with the MAP SBP responder, the AID / USID field can be set to the USID of the MAP SBP initiator.

[0282] (5) The rejection duration indication field can be used by the MAP SBP responder to instruct the MAP SBP initiator not to initiate the MAP SBP process (or not to send a request frame for the MAP SBP process) within the duration indicated by the rejection duration indication field. In the embodiment of the present application, when the status code field carries the request rejection field, the second response frame may also include a rejection duration field. The MAP SBP initiator can learn from the rejection duration field that the MAP SBP responder does not want to receive a request frame for the MAP SBP process (such as a second request frame) again within the duration indicated by the field, thereby improving the interaction efficiency between the MAP SBP initiator and the MAP SBP responder.

[0283] For the description of the MAP SBP parameter element, MAP sensing measurement parameter element, and ISTA available window element in the second response frame, please refer to the second request frame, which will not be described in detail here. The above elements in the second response frame are the relevant parameters recommended by the MAP SBP responder.

[0284] In an embodiment of the present application, the MAP SBP responding end carries the MAP measurement session ID in the second response frame, so that the MAP SBP initiating end can effectively obtain the identifier of the MAP perception measurement session corresponding to the MAP SBP process initiated by the MAP SBP responding end based on the second request frame, so that the MAP SBP initiating end can effectively identify the MAP SBP process it initiated.

[0285] In some further embodiments of the present application, a method for terminating a MAP SBP process is provided.

[0286] The method for terminating the MAP SBP process may be as follows:

[0287] As a possible scenario, when the MAP SBP initiator (such as Fig. 9 STA4 shown) or MAP SBP responder (such as Fig. 9 When the AP1) shown in the figure cannot continue the MAP SBP process due to some reasons, or the MAP SBP process is no longer needed, the MAP SBP initiator or the MAP SBP responder can terminate the MAP SBP process by sending a termination frame.

[0288] As another possible scenario, after the MAP SBP responder has agreed to the second request frame (such as setting the status code field in the MAP SBP response frame (such as the second response frame) sent to the MAP SBP initiator to "success"), it is found that the MAP perception measurement session cannot be established as required. At this time, the MAP SBP responder can send a termination frame to terminate the MAP SBP process established between it and the MAP SBP initiator.

[0289] The MAP SBP termination process shown in the embodiment of the present application may also be referred to as a MAP SBP closing process. The termination frame may also be referred to as a MAP SBP termination frame or other frames with similar functions / roles, which are not listed here one by one.

[0290] Fig.11a This is a format diagram of a termination frame provided in an embodiment of the present application. The termination frame may include at least one of the following: category, public action / protected dual public action, and MAP measurement session identification indication. The MAP measurement session identification indication field can be used to identify a MAP-aware measurement session. The receiving end of the termination frame terminates the MAP-aware measurement session indicated by the MAP-aware session identification indication field through the MAP measurement session ID indication field. For relevant descriptions of the MAP measurement session ID indication field, please refer to Figure 5a and Figure 5b etc., which will not be described in detail here.

[0291] for Fig.11a For the termination frame shown, the termination frame can be used to terminate the MAP SBP process corresponding to the MAP awareness measurement session identified by the MAP measurement session ID indication field between the two communicating parties. The termination frame may include one or more MAP measurement session ID indication fields, each of which can be used to identify a MAP awareness measurement session. Fig.11a A MAP measurement session ID indication field is shown as an example, which should not be understood as a limitation on the embodiments of the present application. The two communicating parties shown in the embodiments of the present application may be a communication device that sends the termination frame and a communication device that receives the termination frame. For example, the two communicating parties may be a MAP SBP initiator and a MAP SBP responder.

[0292] In an embodiment of the present application, the termination frame indicates the MAP SBP process corresponding to the terminated MAP perception measurement session by including one or more MAP measurement session ID indication fields, so that the communication device receiving the termination frame can clearly know which MAP SBP processes corresponding to the MAP perception measurement sessions between it and the communication device sending the termination frame need to be terminated, and the flexibility of indicating the termination of the MAP SBP process corresponding to the MAP perception measurement session is higher.

[0293] Furthermore, if Fig.11b As shown, the termination frame may also include at least one of the following: MAP SBP termination control, MAP SBP parameter element. Exemplarily, the MAPSBP termination control field may include at least one of the following: termination of all MAP SBP procedures, MAP SBP error status. The above fields are described in detail below.

[0294] (1) Terminate all MAP SBP processes The field may be used to indicate whether to terminate all MAP SBP processes between the communicating parties.

[0295] As an example, the value of the Terminate All MAP SBP Processes field is the first value, indicating the termination of all MAP SBP processes between the MAP SBP initiator (such as STA4) and the MAP SBP responder (such as AP1). At this time, the MAP measurement session ID indication field can be set to reserved. Generally speaking, one or more MAP SBP processes can be established between the MAP SBP initiator and the MAP SBP responder. When the value of the Terminate All MAP SBP Processes field in the termination frame is the first value, it can indicate the termination of all MAP SBP processes established between STA4 and AP1. All MAP SBP processes shown in the embodiment of the present application include the MAP SBP processes that have been established by AP1, and the MAP SBP processes that AP1 has agreed to STA4 but has not yet completed the establishment.

[0296] As another example, the value of the field "Terminate All MAP SBP Procedures" is the second value, indicating that the MAP SBP procedure corresponding to the MAP awareness measurement session identified by the MAP Measurement Session ID field initiated by the MAP SBP initiator is terminated.

[0297] Exemplarily, the above-mentioned Terminate All MAP SBP Flows field may occupy 1 bit. For example, the above-mentioned first value may be 1, and the second value may be 0. Of course, the Terminate All MAP SBP Flows field may also occupy more bits, which are not listed here one by one.

[0298] In the embodiment of the present application, as an example, the termination frame may terminate the MAP SBP process. After the MAP SBP process is terminated, the MAP perception measurement session corresponding to the MAP SBP process may also be terminated. At this time, the MAP SBP responder may send a termination frame to the APs participating in the multi-AP collaboration, and use the termination frame to terminate the MAP perception measurement session corresponding to the MAP SBP process. For example, the MAP SBP responder may send a termination frame to each AP participating in the multi-AP collaboration. As another example, the termination frame may be used to terminate the MAP SBP process, or to terminate the MAP perception measurement session corresponding to the MAP SBP process. For example, after receiving the termination frame, the MAP SBP responder needs to terminate both the MAP SBP process and the MAP perception measurement session corresponding to the MAP SBP process.

[0299] (2) The MAP SBP error status field can be used to indicate the reason for terminating the MAP SBP process. Exemplarily, when the MAP SBP error status field is 1, it indicates that the reason for terminating the MAP SBP process is due to the inability to establish the corresponding MAP perception measurement session as required (the MAP perception measurement session is initiated based on the second request frame). At this time, the termination frame may carry at least one of the following items: MAP SBP parameter element (MAP SBP parameterselement) (carrying recommended parameters), MAP perception measurement parameter element, and perception measurement parameter element. When the terminate all MAP SBP processes field is 1, the MAP SBP error status field may be 0. The MAP SBP error status field may also be referred to as the MAP SBP error code field. The embodiment of the present application does not limit the name of this field.

[0300] In the embodiment of the present application, the MAP SBP termination control field and the MAP measurement session ID indication field are used to indicate the termination of one MAP SBP process or all MAP SBP processes between two communicating parties, which can effectively save signaling overhead.

[0301] In a possible implementation, the termination frame may also include one or more MAP measurement session ID indication fields and a MAP SBP termination control field. In this case, the termination frame may terminate a MAP SBP process corresponding to a MAP perception measurement session between the two communicating parties, or a MAP SBP process corresponding to each MAP perception measurement session in multiple MAP perception measurement sessions, or a MAP SBP process corresponding to each MAP perception measurement session in all MAP perception measurement sessions. This implementation will not be described in detail here.

[0302] In an embodiment of the present application, the communication device that sends the termination frame can explicitly instruct the communication device that receives the termination frame to terminate the MAP SBP process corresponding to a certain MAP awareness measurement session between the communicating parties or the MAP SBP process corresponding to all MAP awareness measurement sessions, thereby effectively improving the termination process of the MAP SBP process.

[0303] In still other embodiments of the present application, a method for establishing a perception measurement session is provided.

[0304] The method for establishing a perception measurement session is as follows:

[0305] Fig.12 Schematic diagram of a method for establishing a perception measurement session provided by an embodiment of the present application. Fig.12 As shown, the method includes:

[0306] 1201. The perception measurement initiator sends a third request frame to the perception measurement responder. Correspondingly, the perception measurement responder receives the third request frame.

[0307] The third request frame is used to request to establish a perception measurement session. During the perception measurement session, the perception measurement initiator and the perception measurement responder may establish the perception measurement session through the third request frame and a third response frame in response to the third request frame.

[0308] As a possible implementation method, after the MAP perception measurement initiator and the MAP perception measurement responder exchange the first request frame and the first response frame, the MAP perception measurement initiator can establish a perception measurement session between the STA corresponding to the perception measurement initiator, and the MAP perception measurement responder can also establish a perception measurement session between the STA corresponding to the perception measurement initiator. Alternatively, the MAP perception initiator may not act as the perception measurement initiator and not participate in the perception measurement session. For the relevant description of the first request frame and the first response frame, please refer to Figure 3 , Figure 5a , Figure 5b , Figure 5c wait.

[0309] As another possible implementation method, after the MAP SBP initiator and the MAP SBP responder exchange the second request frame and the second response frame, the MAP SBP responder may establish a MAP perception measurement session between the MAP perception measurement initiator and the MAP perception measurement responder; or, the MAP SBP responder may not act as the MAP perception measurement initiator and not participate in the MAP perception measurement session. The MAP perception measurement initiator may establish a perception measurement session between the perception measurement initiator and its corresponding STA, and the MAP perception measurement responder may also establish a perception measurement session between the perception measurement initiator and its corresponding STA. The STA participating in the perception measurement session may include the MAP SBP initiator or may not include the MAP SBP initiator. For relevant descriptions about the second request frame and the second response frame, please refer to Figure 8 , Fig.10a , Fig.10b , Fig.10c wait.

[0310] The above-listed manners in which the perception measurement initiator initiates a perception measurement session are only examples, and the embodiments of the present application do not limit the specific manner in which the perception measurement initiator initiates the perception measurement session.

[0311] Exemplarily, the third request frame may be referred to as a perception measurement request frame or a protected perception measurement request frame or other frames having similar functions / roles.

[0312] The third request frame in three different frame formats is shown below, respectively as follows:

[0313] Implementation method 1

[0314] The third request frame includes the AID or USID of the MAP SBP initiator. For example, the AID or USID of the MAP SBP initiator may be carried in the perception measurement parameter element in the third request frame. Exemplarily, the perception measurement session element may include a perception subelement, and the perception subelement may include a MAP SBP specific subelement (MAP SBPspecificsubelement).

[0315] Table 1 shows the sensing subelement IDs for sensing parameters. In the embodiment of the present application, a MAP SBP specific subelement is added in the third request frame. The MAP SBP specific subelement can carry the AID or USID of the MAP SBP initiator. The embodiment of the present application does not limit the specific values ​​of the subelement IDs of the MAP SBP specific subelement and the specific values ​​of the subelement IDs of the MAP sensing specific subelement shown in Table 1.

[0316] Table 1

[0317]

[0318] Exemplarily, the AID may include AID12. The USID may include USID12.

[0319] In the embodiment of the present application, the MAP SBP specific sub-element newly added in the third request frame may have a similar structure to the SBP specific sub-element, and the contents contained in the two elements are different. The MAP SBP specific sub-element includes the AID or USID of the MAP SBP initiator. The SBP specific sub-element includes the AID or USID of the SBP initiator. With the advancement of standards, the MAP SBP specific sub-element and the SBP specific sub-element may be merged into one sub-element, which is not limited in the embodiment of the present application. When the MAP SBP specific sub-element and the SBP specific sub-element are merged into one sub-element, the merged sub-element may include the AID or USID of the MAP SBP initiator, and the AID or USID of the SBP initiator.

[0320] In an embodiment of the present application, by including the AID or USID of the MAP SBP initiator in the third request frame, the perception responder can effectively know, after receiving the third request frame, that the perception measurement session established between the perception measurement initiator and the perception measurement responder is a perception measurement session initiated (or called triggered) by MAP SBP, as well as the AID or USID of the MAP SBP initiator.

[0321] Implementation method 2

[0322] The third request frame includes the MAP measurement session ID.

[0323] The MAP measurement session ID can be used to identify the MAP perception measurement session. By carrying the MAP measurement session ID in the third request frame, the perception measurement responder can effectively know whether the third request frames sent from different APs belong to the same MAP perception measurement session. Figure 4aFor example, STA2 can receive the third request frame from AP1 and the third request frame from AP2. STA2 can learn from the MAP measurement session IDs in the third request frames separately sent by these two APs that the MAP sensing measurement session corresponding to the sensing measurement session initiated by AP1 is the same as the MAP sensing measurement session corresponding to the sensing measurement session initiated by AP2. Thus, STA2 can learn that there is a cooperation relationship between these two APs, or STA2 can learn that there is a mechanism to avoid interference between these two APs. At the same time, the flexibility of management can be improved through the MAP measurement session ID.

[0324] Furthermore, the third request frame may further include the MAC address of the MAP sensing measurement initiator. Exemplarily, by including the MAC address of the MAP sensing measurement initiator, STA2 can further learn that the initiator of the MAP sensing measurement session corresponding to the sensing measurement session initiated by AP1 is the same as the initiator of the MAP sensing measurement session corresponding to the sensing measurement session initiated by AP2. The MAC address shown here is only an example. For example, the third request frame may also include the ID of the MAP sensing measurement initiator or other identification information for identifying the MAP sensing measurement initiator, etc. The embodiments of the present application do not limit this. For the length of the identification information used to identify the MAP sensing measurement initiator, it can be adaptively adjusted according to different identification information, and the embodiments of the present application do not limit this.

[0325] Still taking Figure 4a as an example, the third request frame sent by AP1 may include the MAP measurement session ID and the MAC address of AP1, and the third request frame sent by AP2 may also include the MAP measurement session ID and the MAC address of AP1. Thus, STA2 can learn from the third request frames sent by AP1 and AP2 respectively that the third request frames from AP1 and AP2 actually belong to the same MAP sensing measurement session. The MAP sensing measurement session is identified by <MAP sensing measurement initiator, MAP measurement session ID>. Thus, the <MAP sensing measurement initiator, MAP measurement session ID> in the third request frame sent by the MAP sensing measurement initiator to its corresponding STA is the same as the <MAP sensing measurement initiator, MAP measurement session ID> in the third request frame sent by the MAP sensing response end to its corresponding STA.

[0326] Reusing Table 1, in the embodiments of the present application, a new MAP sensing specific sub - element is added to the sensing sub - element in the third request frame. This MAP sensing specific sub - element may include the MAC address of the MAP sensing measurement initiator and the MAP measurement session ID.

[0327] The MAP sensing specific sub-element may be carried in a sensing sub-element in a sensing measurement parameter element in the third request frame.

[0328] Fig.13a This is a schematic diagram of the format of a third request frame provided in an embodiment of the present application. Fig.13a The example of the MAC address of the MAP sensing measurement initiator and the MAP measurement session ID being carried in the same MAP sensing specific sub-element is used for illustration. In a specific implementation, these two fields may be carried in different sub-elements respectively, which is not limited in the embodiment of the present application.

[0329] about Fig.13a Other descriptions will not be described in detail here.

[0330] Generally speaking, the establishment of a MAP perception measurement session occurs between APs, and the MAP measurement session ID is also exchanged between APs. When the AP establishes a perception measurement session with each STA, the AP can inform each STA that the perception measurement session is a perception measurement session under a MAP perception measurement session. In an embodiment of the present application, the third request frame includes the MAP measurement session ID (or the MAP measurement session ID and the MAC address of the MAP perception measurement initiator), so that the perception responder can effectively know that the perception measurement sessions initiated by multiple APs actually belong to the same MAP perception measurement session.

[0331] Implementation method three

[0332] The third request frame includes the number of APs participating in the MAP perception measurement session, the MAC addresses of the APs participating in the MAP perception measurement session, and the measurement session ID of the perception measurement session initiated by the perception measurement initiator. The number of APs is consistent with the number of MAC addresses.

[0333] Similar to the above-mentioned implementation method 2, a MAP perception specific sub-element may be added to the perception sub-element in the third request frame, and the MAP perception specific sub-element may include the number of APs participating in the MAP perception measurement session, the MAC addresses of each AP participating in the MAP perception measurement session, and the measurement session ID of the perception measurement session initiated by the perception measurement initiator. The MAC address shown here is only an example, and the third request frame may also include the ID of each AP participating in the MAP perception measurement session or other identification information of the AP, etc., which is not limited in the embodiments of the present application.

[0334] If still Figure 4aFor example, the third request frame sent by AP1 may include the number of APs participating in the MAP perception measurement session (such as the number of APs is 2), the MAC addresses of the APs participating in the MAP perception measurement session (such as AP1 and AP2), and the ID of the perception measurement session initiated by AP1. The third request frame sent by AP2 may include the number of APs participating in the MAP perception measurement session (such as the number of APs is 2), the MAC addresses of the APs participating in the MAP perception measurement session (such as AP1 and AP2), and the ID of the perception measurement session initiated by AP2. Among them, the <number of APs participating in the MAP perception measurement session, the MAC addresses of the APs participating in the MAP perception measurement session> in the third request frame sent by AP1 are the same as the <number of APs participating in the MAP perception measurement session, the MAC addresses of the APs participating in the MAP perception measurement session> in the third request frame sent by AP2. The ID of the perception measurement session initiated by AP1 may be different from or the same as the ID of the perception measurement session initiated by AP2, and this is not limited in the embodiments of the present application.

[0335] Exemplarily, in order to clearly inform each STA which AP is the initiator of the MAP-aware measurement session, the MAC address of the MAP-aware measurement initiator in the third request frame may be located in a predetermined field in the MAC addresses of each AP participating in the MAP-aware measurement session. Figure 4a For example, the MAC address of AP1 may be located in the first MAP address field of the two MAC address fields (eg, the MAC address of AP1 is ranked first in the two MAC addresses).

[0336] Fig.13b This is a schematic diagram of the format of a third request frame provided in an embodiment of the present application. Fig.13b The MAP number field in may be used to carry the number of APs participating in the MAP awareness measurement session, or the number of APs participating in the MAP awareness measurement session+1, or the number of APs participating in the MAP awareness measurement session-1. Fig.13b The MAP-aware AP MAC address field in the MAP-aware AP MAC address field may be used to carry the MAC address of each AP participating in the MAP-aware measurement session. Fig.13b The measurement session ID indication field in the AP may be used to indicate the measurement session ID of the awareness measurement session initiated by each AP bearer. Fig.13b The MAC address shown is only an example and should not be construed as a limitation on the embodiments of the present application.

[0337] In the embodiment of the present application, the perception responder can effectively learn how many APs are involved in the MAP perception measurement session, what are the MAC addresses of these APs, and what is the measurement session ID of the perception measurement session initiated by the AP belonging to the same MAP perception session by parsing the third request frame. The MAP measurement session ID may not be introduced in the third request frame, and the perception responder can associate the perception measurement session between the AP and each STA to the same MAP perception measurement session. As a result, STA2 can learn that there is a cooperative relationship between the two APs, or STA2 can learn that there is a mechanism to avoid interference between the two APs.

[0338] The above implementation method 1 can be combined with implementation method 2 or implementation method 3, for example, the third request frame can include both the MAP SBP specific sub-element shown in implementation method 1 and the MAP sensing specific sub-element shown in implementation method 2; and the third request frame can include both the MAP SBP specific sub-element shown in implementation method 1 and the MAP sensing specific sub-element shown in implementation method 3. The specific description of the combination will not be described in detail here.

[0339] 1202. The perception measurement responding end sends a third response frame, and correspondingly, the perception measurement initiating end receives the third response frame.

[0340] Exemplarily, the third response frame may include information in the third request frame for identifying the MAP perception measurement session. For example, the third response frame may include the AID or USID of the MAP SBP initiator. For another example, the third response frame may include the MAP measurement session ID. For another example, the third response frame may include the number of APs participating in the MAP perception measurement session, the MAC addresses of each AP participating in the MAP perception measurement session, and the measurement session ID of the perception measurement session initiated by the perception measurement initiator. For relevant instructions on the third response frame, please refer to the above-mentioned implementation methods 1 to 3, which will not be described in detail here.

[0341] Exemplarily, the third response frame may be called a perception measurement response frame or a protected perception measurement response frame, etc.

[0342] In the embodiment of the present application, by including the above-mentioned MAP SBP specific sub-element or MAP perception specific sub-element in the third request frame, the perception responder can effectively know which perception measurement sessions belong to the same MAP SBP process or MAP perception measurement session.

[0343] In still other embodiments of the present application, a method for terminating a perception measurement session is provided.

[0344] After the AP and the STA complete the establishment of the perception measurement session, the perception measurement will be performed. When the perception measurement session is no longer needed, it can be terminated through a termination frame. When terminating through the termination frame, the communicating parties can choose to terminate the perception measurement session between the AP and the STA, or terminate the MAP perception measurement session corresponding to the perception measurement session between the AP and the STA. The termination frame can be sent by the perception measurement initiator to the perception measurement responder, or by the perception measurement responder to the perception measurement initiator, and this is not limited in the embodiments of the present application. The communicating parties shown in the embodiments of the present application can be a communication device that sends a termination frame and a communication device that receives the termination frame. For example, the communicating parties can be a perception measurement initiator and a perception measurement responder, or the communicating parties can be two perception measurement responders.

[0345] For example, the following Figures 14a to 14c The termination frame shown can be applicable to implementation method 2 and implementation method 3. As shown in the third request frame shown above, combined with the termination frame below, after the perception measurement session is established (such as completing the establishment of the perception measurement session through the third request frame and the third response frame above), the AP or STA can terminate the perception measurement session or MAP perception measurement session through the termination frame. Fig.14d The termination frame shown in the above implementation mode can be applicable to the second implementation mode. For example, the third request frame shown in the above implementation mode can be used in the following Fig.14d The termination frame shown is combined. Fig.14e The termination frame shown in the above implementation mode can be applied to the third implementation mode. For example, the third request frame shown in the above implementation mode can be applied to the third implementation mode. Fig.14e The termination frame combination shown.

[0346] Example 1

[0347] Fig.14a This is a format diagram of a termination frame provided in an embodiment of the present application. The termination frame may include at least one of the following: category, public action / protected dual public action, and measurement session identification indication. The measurement session identification indication field can be used to identify a perception measurement session. The receiving end of the termination frame can terminate the perception measurement session indicated by the measurement session identification indication field through the measurement session ID indication field. The measurement session ID indication field may include a measurement session ID field. The format of the measurement session identification indication field can be referred to above and will not be described in detail here.

[0348] The termination frame may be used to terminate the perception measurement session identified by the measurement session ID indication field between the two communicating parties. The termination frame may include one or more measurement session ID indication fields, each of which may be used to identify a perception measurement session. Fig.14a A MAP measurement session ID indication field is shown by way of example, which should not be construed as a limitation on the embodiments of the present application.

[0349] In an embodiment of the present application, the termination frame indicates the terminated perception measurement session by including one or more measurement session ID indication fields, so that the communication device receiving the termination frame can clearly know which perception measurement sessions need to be terminated between it and the communication device sending the termination frame, thereby providing greater flexibility in indicating the termination of the perception measurement session.

[0350] Example 2

[0351] Fig.14b FIG. 1 is a schematic diagram of another format of a termination frame provided in an embodiment of the present application. Fig.14a For the termination frame shown in FIG. 1 , the termination frame may also include a measurement session termination control field. The measurement session termination control field may include a MAP field. For descriptions of other fields of the termination frame, please refer to Fig.14a , which will not be described in detail here.

[0352] The combination of the measurement session ID field and the MAP field in the termination frame can indicate whether to terminate one or more perception measurement sessions between the AP and the STA, or to terminate the MAP perception measurement session corresponding to the perception measurement session between the AP and the STA.

[0353] As an example, when the value of the MAP field is the first value, it may indicate that the MAP awareness measurement session corresponding to the awareness measurement session identified by the measurement session ID field is terminated.

[0354] by Figure 4a For example, if AP1 sends a termination frame to STA2, and the value of the MAP field in the termination frame is the first value, it means that the MAP perception measurement session corresponding to the perception measurement session identified by the measurement session ID field between AP1 and STA2 is terminated, or it means that the perception measurement session corresponding to the perception measurement session identified by the measurement session ID field is terminated in which STA2 participates. The termination frame can be used to terminate the perception measurement session between AP1 and STA2, and the perception measurement session between AP2 and STA2. At this time, the perception measurement session between AP1 and STA1 is still continuing, and the perception measurement session between AP2 and STA3 is still continuing.

[0355] by Figure 4a For example, if AP2 sends a termination frame to STA2, and the value of the MAP field of the termination frame is the first value, it means that the MAP perception measurement session corresponding to the perception measurement session identified by the measurement session ID field between AP2 and STA2 is terminated, or it means that the perception measurement session corresponding to the perception measurement session identified by the measurement session ID field is terminated in which STA2 participates. The termination frame can be used to terminate the perception measurement session between AP2 and STA2, as well as the perception measurement session between AP1 and STA2.

[0356] by Figure 4a For example, if STA1 sends a termination frame to AP1, and the value of the MAP field in the termination frame is the first value, it means that the MAP perception measurement session corresponding to the perception measurement session identified by the measurement session ID field between STA1 and AP1 is terminated, or it means that the perception measurement session corresponding to the perception measurement session identified by the measurement session ID field is terminated in which STA1 participates. The termination frame can be used to terminate the perception measurement session between AP1 and STA1. At this time, the perception measurement session between AP1 and STA2 is still being executed, and the perception measurement sessions between AP2 and STA2 and STA3 are still being executed.

[0357] As another example, when the value of MAP is the second value, it may indicate that the perception measurement session identified by the measurement session ID field is terminated.

[0358] by Figure 4a For example, if AP1 sends a termination frame to STA2, and the value of the MAP field in the termination frame is the second value, it means that the perception measurement session between AP1 and STA2 identified by the measurement session ID field is terminated. In this case, the perception measurement session between AP1 and STA1 can continue to be executed. In this example, if the perception measurement session between AP2 and STA2 also needs to be terminated, AP2 needs to send a termination frame to STA2, and the value of the MAP field in the termination frame is the second value.

[0359] In the embodiment of the present application, one or more measurement session ID fields may be used in the termination frame. If multiple perception measurement sessions are established between AP1 and STA1, the value of the MAP field in the termination frame is the second value, and the termination frame includes two measurement session ID fields, which indicates that two perception measurement sessions identified by the two measurement session ID fields between AP1 and STA1 are terminated.

[0360] Exemplarily, the MAP field may occupy 1 bit. For example, the first value may be 1, and the second value may be 0. Of course, the MAP field may occupy more bits, which are not listed here.

[0361] In the embodiment of the present application, the MAP field is combined with the measurement session ID field to effectively indicate the termination of the MAP perception measurement session and its corresponding perception measurement session, and the termination of the perception measurement session is more efficient.

[0362] Example 3

[0363] Fig.14c FIG. 1 is another format diagram of a termination frame provided in an embodiment of the present application. Fig.14c As shown, the measurement session termination control field in the termination frame may include a termination all measurement sessions field and a MAP field.

[0364] As an example, when the value of the Terminate All Measurement Sessions field is the first value and the value of the MAP field is the first value, it may indicate that the MAP awareness measurement session corresponding to the awareness measurement session between the communicating parties is terminated.

[0365] When the value of the Terminate All Measurement Sessions field is the first value, the Measurement Session ID field is set to Reserved. Therefore, when the value of the Terminate All Measurement Sessions field is the first value and the value of the MAP field is the first value, all MAP-aware measurement sessions between the communicating parties are terminated by the termination frame.

[0366] by Figure 4a For example, if the value of the Terminate All Measurement Sessions field in the termination frame sent by AP1 to STA2 is the first value, and the value of the MAP field is the first value, it means that all MAP perception measurement sessions corresponding to the perception measurement session between AP1 and STA2 are terminated, or it means that all MAP perception measurement sessions corresponding to the perception measurement session in which STA2 participates are terminated. At this time, the perception measurement session between AP2 and STA2 will also be terminated. If multiple perception measurement sessions are established between AP1 and STA2, when the value of the Terminate All Measurement Sessions field in the termination frame sent by AP1 to STA2 is the first value, and the value of the MAP field is the first value, it means that all MAP perception measurement sessions corresponding to the multiple perception measurement sessions between AP1 and STA2 are terminated.

[0367] As another example, when the value of the Terminate All Measurement Sessions field is a first value and the value of the MAP field is a second value, it may indicate that all perception measurement sessions between the communicating parties are terminated.

[0368] by Figure 4aFor example, the value of the Terminate All Measurement Sessions field in the termination frame sent by AP1 to STA2 is the first value, and the value of the MAP field is the second value, which indicates that all perception measurement sessions between AP1 and STA2 are terminated. At this time, the perception measurement session between AP1 and STA2 is terminated, but the perception measurement session between AP1 and STA1 continues to be executed, and the perception measurement sessions between AP2 and STA2 and STA3 continue to be executed.

[0369] As another example, when the value of the Terminate All Measurement Sessions field is the second value and the value of the MAP field is the first value, it may indicate terminating the MAP awareness measurement session corresponding to the awareness measurement session identified by the Measurement Session ID field between the communicating parties.

[0370] When the value of the Terminate All Measurement Sessions field is the second value, the Measurement Session ID field carries the Measurement Session ID. Therefore, when the value of the Terminate All Measurement Sessions field in the termination frame is the second value and the value of the MAP field is the first value, it can indicate that the MAP perception measurement session corresponding to the perception measurement session identified by the Measurement Session ID field between the two communicating parties is terminated.

[0371] For example, multiple perception measurement sessions are established between AP1 and STA2. When the value of the Terminate All Measurement Sessions field in the termination frame sent by AP1 to STA2 is the second value and the value of the MAP field is the first value, it means that the MAP perception measurement session corresponding to a perception measurement session identified by the measurement session ID field between AP1 and STA2 is terminated. At this time, when AP2 also participates in the MAP perception measurement session and a perception measurement session is established between AP2 and STA2, the MAP perception measurement session between AP2 and STA2 will be terminated.

[0372] As another example, the value of the Terminate All Measurement Sessions field is the second value, and the value of the MAP field is the second value, which may indicate terminating the perception measurement session identified by the Measurement Session ID field between the communicating parties.

[0373] When the value of the Terminate All Measurement Sessions field is the second value, the Measurement Session ID field carries the Measurement Session ID. Therefore, when the value of the Terminate All Measurement Sessions field in the termination frame is the second value and the value of the MAP field is the second value, it can indicate that the perception measurement session (measurementsession ID, MSID) identified by the Measurement Session ID field between the two communicating parties is terminated.

[0374] Exemplarily, the above-mentioned field for terminating all measurement sessions may occupy 1 bit. For example, the first value may be 1 and the second value may be 0. Of course, the field for terminating all measurement sessions may also occupy more bits, which will not be enumerated one by one here.

[0375] For the above Examples 1 to 3, as a possible implementation, the termination frame may further include at least one of the following: the MAC address of the MAP sensing measurement initiating end, the MAP measurement session ID indication. As another possible implementation, the termination frame may further include at least one of the following: the number of APs participating in the MAP sensing measurement session, the MAC addresses of the respective APs participating in the MAP sensing measurement session, the MAP measurement session ID indication.

[0376] Fig.14d It is a schematic diagram of the format of another termination frame provided by an embodiment of the present application. As Fig.14d shown, the measurement session termination control field in this termination frame may include termination of all TB measurement sessions (terminationall TBmeasurementsession), termination of all non-TB measurement sessions (terminationallnon-TBmeasurementsession), TB / non-TB measurement session type (TB / non-TB measurementsessiontype), MAP. Exemplarily, this termination frame may further include a MAP sensing initiating AP MAC address field and a MAP measurement session ID indication field. The MAP sensing initiating AP MAC address field may be used to carry the MAC address of the MAP sensing measurement initiating end.

[0377] As shown in the above Implementation 2, the MAP sensing measurement session may be identified by <the MAC address of the MAP sensing measurement initiating end, the MAP measurement session ID>. Therefore, when the frame format of the third request frame is the same as the frame format shown in the above Implementation 2, since an association is established between the sensing measurement session between the AP and its respective STA and the MAP sensing measurement session during the establishment of the sensing measurement session, the MAP sensing initiating AP MAC address field and the MAP measurement session ID indication field in the termination frame are both optional.

[0378] Fig.14e It is a schematic diagram of the format of another termination frame provided by an embodiment of the present application. As Fig.14eAs shown, the measurement session termination control field in the termination frame may include termination of all TB measurement sessions (terminationall TBmeasurementsession), termination of all non-TB measurement sessions (terminationallnon-TBmeasurementsession), TB / non-TB measurement session type (TB / non-TBmeasurementsessiontype), and MAP. Exemplarily, the termination frame may also include a MAP quantity field, a MAP-aware AP MAC address field, and a MAP measurement session ID indication field. The MAP-aware AP MAC address field may be used to carry the MAC addresses of each AP participating in the MAP-aware measurement session.

[0379] As shown in the third implementation, the MAP perception measurement session can be identified by <the number of APs participating in the MAP perception measurement session, the MAC address of each AP participating in the MAP perception measurement session>. Therefore, when the frame format of the third request frame is the frame format shown in the third implementation, since the perception measurement session between the AP and each STA is associated with the MAP perception measurement session during the establishment of the perception measurement session, the MAP number field, the MAP perception AP MAC address field, and the MAP measurement session ID indication field in the termination frame are all optional.

[0380] In the embodiment of the present application, the termination frame can effectively terminate the perception measurement session or the MAP perception measurement session, thereby improving the flexibility of termination.

[0381] In some further embodiments of the present application, a control frame is provided.

[0382] This control frame can be used in the sensing measurement interaction process between AP and STA. Generally speaking, after the establishment of the sensing measurement session between AP and STA, the sensing initiator can initiate one or more sensing measurement interactions (sensingmeasurement exchange). The sensing measurement interaction can be divided into trigger-based (TB) sensing measurement interaction (TB sensing measurement instance) and non-trigger-based (non-TB) sensing measurement interaction (Non-TB sensing measurement instance). Exemplarily, the TB sensing measurement interaction may include at least one of the following stages: polling stage, NDPA sounding stage, trigger frame (TF) sounding stage and reporting stage. The control frame shown in the embodiment of the present application may be a frame in a perception measurement interaction process, such as a frame sent by an AP during a perception measurement interaction process, such as a control frame may be at least one of the following: a perception polling trigger frame, a perception null data packet announcement (null data packet announcement, NDPA) frame (sensing NDP announcement frame), a perception responder to sensing initiator (sensing responder to sensing initiator, SR2SI) sounding trigger frame (SR2SI sounding trigger frame), a sensing SR2SR sounding trigger frame (sensing SR2SR sounding trigger frame), a sensing report trigger frame (sensing report trigger frame), a clear send (cleantosend, CTS) to self (CTS-to-self, CST2SELT) frame, and a perception measurement report frame.

[0383] For example, if there are n APs participating in the MAP perception measurement session, the perception measurement sessions corresponding to some of the n APs may be terminated through the control frame. At this time, other unterminated APs may continue to perform perception measurement with their respective corresponding STAs.

[0384] by Figure 4bFor example, the APs participating in the MAP perception measurement session initiated by AP1 are AP1, AP2, and AP3. AP1 can instruct the STA to terminate the perception measurement session of AP2 in the MAP perception measurement session initiated by it, without terminating the entire MAP perception measurement session initiated by AP1. At this time, AP1 can continue to perform measurements with its corresponding STA, and AP3 can continue to perform process measurements with its corresponding STA. For example, AP1 can send a control frame to STA2, indicating through the control frame that the perception measurement session corresponding to the MAP perception measurement session initiated by AP1 between STA2 and AP2 is terminated.

[0385] Fig.15 is a flow chart of a perception communication method provided by an embodiment of the present application. Fig.15 As shown, the method includes:

[0386] 1501. A perception measurement initiator sends a control frame to a perception measurement responder, and the perception measurement responder receives the control frame. The control frame may include indication information, and the indication information may be used to indicate to the perception responder that a perception measurement session corresponding to at least one AP in a MAP perception measurement session identified by a MAP measurement session ID field is terminated.

[0387] Fig.16 It is a schematic diagram of the format of a control frame provided in an embodiment of the present application. Fig.16 Only some fields in the control frame are shown exemplarily, and other fields in the control frame are not limited in this embodiment of the application. Fig.16 The information carried by at least one field shown. Fig.16 As shown, the control frame includes a termination field, a MAP sensing initiator AP address, a MAP measurement session ID indication, a MAP sensing responder AP address, a MAP sensing initiator AP identifier, and a MAP sensing responder AP identifier.

[0388] Among them, the MAP sensing initiating end AP address field can be used to carry the address of the initiating end of the MAP sensing measurement session. Exemplarily, this MAP sensing initiating end AP address field can be used to carry the MAC address of the initiating end of the MAP sensing measurement session. The MAP measurement session ID indication field can be used to carry the identifier of the MAP sensing measurement session. The MAP sensing responding end AP address can be used to carry the address of the responding end of the MAP sensing measurement session. Exemplarily, this MAP sensing responding end AP address can be used to carry the MAC address of the responding end of the MAP sensing measurement session. The MAP sensing initiating end AP identification field can be used to carry the identification information (such as AID or BSSID, etc.) of the initiating end of the MAP sensing measurement session. The MAP sensing responding end AP identification field can be used to carry the identification information of the responding end of the MAP sensing measurement session. Fig.16 Exemplarily, a responding end of a MAP sensing measurement session is shown, but it should not be construed as a limitation to the embodiments of the present application. For example, in a specific implementation, the control frame may also include multiple MAP sensing responding end AP address fields (or multiple MAP sensing responding end identification fields), and each MAP sensing responding end AP address field can be used to carry the address of a responding end of the MAP sensing measurement session.

[0389] The termination field can be used to indicate whether to terminate. For example, when the value of the termination field is the first value, it can indicate terminating the sensing measurement session of the responding end indicated by the MAP sensing responding end AP MAC address field in the MAP sensing measurement session identified by the MAP measurement session ID field initiated by the initiating end indicated by the MAP sensing initiating end AP MAC address field.

[0390] Exemplarily, the control frame may further include a terminated AP quantity (number of terminated AP) field, and this terminated AP quantity field can be used to indicate the number of APs of the terminated sensing measurement sessions in the MAP sensing measurement session identified by <the MAP sensing measurement initiating end identified by the MAP sensing initiating end AP MAC address field, the MAP sensing measurement session identified by the MAP measurement session ID field>. Fig.16 In which n represents the number of terminated APs.

[0391] The above control frame may be sent by the perception measurement initiator to the perception measurement responder during the process of the perception measurement interaction between the perception measurement initiator and the perception measurement responder. For example, the control frame may be any one of the following: a perception polling trigger frame, a perception NDPA frame, a perception SR2SI sounding trigger frame, a perception SR2SI sounding trigger frame, a perception SR2SR sounding trigger frame, a perception reporting trigger frame, and a perception threshold-based reporting trigger frame.

[0392] As an example, Fig.16 The various fields shown can be carried in the trigger dependent common info field in any of the following frames: perception polling trigger frame, perception SR2SI detection trigger frame, perception report trigger frame, perception threshold-based report trigger frame, perception SR2SR detection trigger frame. At this time, one or more perception measurement responders that receive the control frame can be informed of the termination of the perception measurement session in which at least one AP participates.

[0393] by Figure 4bFor example, AP1 sends a control frame to STA2. In the trigger-related public information field in the control frame, the MAP perception initiator AP MAC address field carries the MAC address of AP1, the MAP measurement session ID indication field carries the ID of the MAP perception measurement session (such as ID1), the MAP perception responder AP MAC address field carries the MAC address of AP2, and the termination field takes the first value (such as 1). Based on the control frame, STA2 can effectively know that in the MAP perception measurement session with ID 1 initiated by AP1, the perception measurement session initiated (or established, or corresponding) by AP2 is terminated (it can also be considered that AP2 needs to exit the MAP perception measurement session with ID 1). The perception measurement session corresponding to the MAP perception measurement session with ID 1 between AP2 and STA2 is terminated, and the perception measurement session corresponding to the MAP perception measurement session with ID 1 between AP2 and STA3 is also terminated. At this time, the perception measurement session corresponding to the MAP perception measurement session with ID 1 between AP1 and STA1 and STA2 is still continuing to execute. The perception measurement session corresponding to the MAP perception measurement session with ID 1 between AP3 and STA4 is still continuing to execute. Exemplarily, the reason why AP1 may send the control frame to STA2 is that AP2 has indicated to AP1 through a termination frame that AP2 has terminated the MAP awareness measurement session.

[0394] by Figure 4b For example, AP1 sends a control frame to STA2, in which the MAP perception initiator AP MAC address field carries the MAC address of AP1, the MAP measurement session ID indication field carries the ID of the MAP perception measurement session (such as ID1), the first MAP perception responder AP MAC address field carries the MAC address of AP2, and the second MAP perception responder AP MAC address field carries the MAC address of AP3. Based on the control frame, STA2 can effectively learn that in the MAP perception measurement session with ID 1 initiated by AP, the perception measurement session initiated by AP2 and AP3 is terminated. The perception measurement session corresponding to the MAP perception measurement session with ID1 between AP2 and STA3 and between AP2 and STA2 is terminated, and the perception measurement session corresponding to the MAP perception measurement session with ID1 between AP3 and STA4 is terminated. At this time, the perception measurement session corresponding to the MAP perception measurement session with ID 1 between AP1 and STA1 and STA2 continues to be executed. Exemplarily, AP1 may send the control frame to STA2 because AP2 has indicated to AP1 through a termination frame that it has terminated the MAP-aware measurement session, and AP3 has also indicated to AP1 through a termination frame that it has terminated the MAP-aware measurement session.

[0395] As another example, Fig.16The various fields shown may be carried in the user information field (userinfofield) in any of the following frames: a perception polling trigger frame, a perception SR2SI detection trigger frame, a perception report trigger frame, a perception threshold-based report trigger frame, and a perception SR2SR detection trigger frame. At this time, the perception measurement responder receiving the control frame may learn that the perception measurement session in which at least one AP participates is terminated.

[0396] by Figure 4b For example, AP1 sends a control frame to STA2. In the user information field of the control frame, the MAP perception initiator AP MAC address field carries the MAC address of AP1, the MAP measurement session ID indication field carries the ID of the MAP perception measurement session (such as ID1), and the MAP perception responder AP MAC address field carries the MAC address of AP2. Based on the control frame, STA2 can effectively learn that in the MAP perception measurement session with ID 1 initiated by AP1, the perception measurement session corresponding to the MAP perception measurement session with ID1 between AP2 and STA2 is terminated, and the perception measurement session corresponding to the MAP perception measurement session with ID1 between AP2 and STA3 is also terminated. At this time, the perception measurement session corresponding to the MAP perception measurement session with ID 1 between AP1 and STA1 and STA2 is still continuing to execute. The perception measurement session corresponding to the MAP perception measurement session with ID 1 between AP3 and STA4 is still continuing to execute.

[0397] As another example, Fig.16 The various fields shown may be carried in the STA info of one or more specific AIDs in the perceived NDPA frame. For example, the value of the specific AID is greater than or equal to 2008. As another example, Fig.16 The fields shown may be carried in the STA Info field corresponding to a certain STA. For example, the AID of the certain STA may be less than 2008.

[0398] 1502. The perception measurement responder parses the control frame.

[0399] By parsing the above control frame, the perception measurement responder can effectively learn whether the MAP perception measurement session of other APs corresponding to it is terminated.

[0400] In the embodiment of the present application, the perception measurement initiator indicates to the perception measurement responder through a control frame which APs' perception measurement sessions are terminated, so that the perception measurement responder can release resources in time based on the control frame to save resources.

[0401] In some other embodiments of the present application, the concept of MAP measurement session ID may not be introduced. The MAP sensing measurement session ID indication field shown above may also be replaced by a sensing measurement session ID indication field, which may be used to carry the ID of the sensing measurement session.

[0402] Exemplarily, during the process of establishing a MAP perception measurement session, APs first exchange measurement session IDs, and the measurement session ID can be used to identify the perception measurement sessions between the APs participating in the MAP perception measurement session and their respective STAs. When each AP participating in the MAP perception measurement session establishes a perception measurement session with its respective STA, the measurement session IDs in the third request frames sent by each AP are the same, and the measurement session ID is the measurement session ID indicated by the perception measurement session ID indication field.

[0403] by Figure 4a For example, AP1 and AP2 can exchange the measurement session ID through the first request frame and the first response frame.
