Description

Wireless communication method, device, equipment, and storage medium Technical Field

[0001] The embodiments of the present application relate to the field of mobile communication technology, and specifically to a wireless communication method and apparatus, device, and storage medium. Background Art

[0002] Wireless sensing technology is a wireless sensing method that reuses existing wireless signals in the environment and analyzes the changes in wireless signals during propagation to obtain the characteristics of the signal propagation space (channel) to achieve scene perception. For example, Wireless Fidelity (Wi-Fi) Sensing implements motion detection, gesture recognition, and biometric measurement based on existing wireless signals between Wi-Fi networks and devices. In Wi-Fi Sensing, changes in the environment caused by the movement of objects, pets, and people are detected by using methods based on Channel State Information (CSI) or radar, without the need for the detected objects to wear any equipment. Through the implementation of wireless sensing, more intelligent and richer applications can be provided in smart homes, intrusion detection, healthcare, smart remote care and other fields.

[0058] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0059] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), or other communication systems. WLAN can support frequency bands including, but not limited to, low frequency bands (2.4 GHz, 5 GHz, 6 GHz) and high frequency bands (60 GHz).

[0060] FIG1 is an example of a communication system architecture applied in an embodiment of the present application.

[0061] As shown in FIG1 , the communication system 100 may include an AP 110 and a STA 120 that accesses the network through the AP 110. In some scenarios, the AP 110 may be referred to as an AP STA, meaning that, in a sense, the AP 110 is also a type of STA. In some scenarios, the STA 120 may be referred to as a non-AP STA. In some scenarios, the STA 120 may include both AP STAs and non-AP STAs. Communication in the communication system 100 may include communication between the AP 110 and the STA 120, communication between the STA 120 and another STA 120, or communication between the STA 120 and a peer STA. A peer STA may refer to a device communicating with the STA 120, for example, a peer STA may be an AP or a non-AP STA.

[0062] AP 110 can be used as a bridge between wired and wireless networks, connecting wireless network clients together and then connecting the wireless network to Ethernet. AP 110 can be a terminal device (such as a mobile phone) or a network device (such as a router) equipped with a WiFi chip.

[0063] It should be noted that the role of STA 120 in the communication system is not absolute. In other words, the role of STA 120 in the communication system can switch between AP and STA. For example, in some scenarios, when a mobile phone is connected to a router, the mobile phone is a STA. When the mobile phone is used as a hotspot for other mobile phones, the mobile phone plays the role of AP.

[0064] In some embodiments, AP 110 and STA 120 can be devices used in the Internet of Vehicles, IoT nodes and sensors in the Internet of Things (IoT), smart cameras, smart remote controls, smart water and electricity meters in smart homes, and sensors in smart cities.

[0065] In some embodiments, AP 110 may be a device supporting the 802.11be standard. The AP may also be a device supporting various current and future 802.11 family WLAN standards, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a. In some embodiments, STA 120 may support the 802.11be standard. The STA may also support various current and future 802.11 family WLAN standards, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0066] In some embodiments, AP 110 and / or STA 120 can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; can also be deployed on the water surface (such as a ship); can also be deployed in the air (for example, on an airplane, balloon, and satellite, etc.).

[0067] In some embodiments, STA 120 may be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) device, an augmented reality (AR) device, a wireless device in industrial control, a set-top box, a wireless device in self-driving, an in-vehicle communication device, a wireless device in remote medical, a wireless device in a smart grid, a wireless device in transportation safety, a wireless device in a smart city or a wireless device in a smart home, an in-vehicle communication device, a wireless communication chip / application specific integrated circuit (ASIC) / system on chip (SoC), etc. that supports WLAN / WiFi technology.

[0068] For example, STA 120 can also be a wearable device. Wearable devices can also be called wearable smart devices, which are a general term for wearable devices that use wearable technology to intelligently design and develop wearable devices, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not just hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. In a broad sense, wearable smart devices include those that are full-featured, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0069] It should be understood that Figure 1 is merely an example of the present application and should not be construed as limiting the present application. For example, Figure 1 only exemplarily illustrates one AP and two STAs. In some embodiments, the communication system 100 may include multiple APs and other numbers of STAs, which are not limited in this embodiment of the present application.

[0070] FIG2A is a schematic diagram of an application scenario of an embodiment of the present application.

[0071] As shown in Figure 2A, communication system 200 may include an AP multi-link device (MLD) 210 and a non-AP MLD 220. AP MLD 210 is an electronic device capable of forming a wireless local area network (WLAN) 230 based on transmitted signals, such as a router or a mobile phone with a hotspot function. Non-AP MLD 220 is an electronic device connected to the WLAN 230 formed by AP MLD 210, such as a mobile phone, smart washing machine, air conditioner, or electronic lock. Non-AP MLD 220 communicates with AP MLD 210 via WLAN 230. AP MLD 210 may be a soft AP MLD, a mobile AP MLD, or the like.

[0072] As shown in FIG2B , in the communication system described in FIG2A , AP MLD 210 is associated with at least two APs 2101, and non-AP MLD 220 is associated with at least two STAs (STAs) 2201. Each AP is connected to a different STA in non-AP MLD 220 via a different link. An AP associated with an AP MLD is also referred to as an AP MLD-associated AP, and a STA associated with a non-AP MLD is also referred to as a non-AP MLD-associated STA.

[0073] In the embodiments of the present application, the AP MLD 210 and the non-AP MLD 220 may be terminal devices, which may refer to access terminals, user equipment (UE), subscriber units, subscriber stations, mobile stations, mobile stations, remote stations, remote terminals, mobile devices, user terminals, terminals, wireless communication devices, user agents, or user devices. Access terminals may be cellular phones, cordless phones, Session Initiation Protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to wireless modems, in-vehicle devices, wearable devices, terminal devices in 5th generation (5G) networks, or terminal devices in future-evolved public land mobile networks (PLMNs), etc.

[0074] The communication system 200 shown in Figure 2A may also include a network device, which may be an access network device that communicates with a terminal device. The access network device may provide communication coverage for a specific geographical area and may communicate with terminal devices within the coverage area.

[0075] FIG2A exemplarily shows an AP MLD and a non-AP MLD. Optionally, the wireless communication system 200 may include multiple non-AP MLDs connected to the wireless local area network 230 , which is not limited in this embodiment of the present application.

[0076] It should be noted that Figures 1, 2A, and 2B are merely examples of the systems to which this application applies. Of course, the methods described in the embodiments of this application can also be applied to other systems. Furthermore, the terms "system" and "network" are often used interchangeably herein. The term "and / or" herein simply describes an association relationship between associated objects, indicating that three possible relationships can exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " herein generally indicates that the associated objects are in an "or" relationship. It should also be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an associated relationship. For example, "A indicates B" can mean that A directly indicates B, for example, B can obtain information through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can obtain information through C; it can also mean that A and B have an associated relationship. It should also be understood that the “correspondence” mentioned in the embodiments of the present application may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc. It should also be understood that the “predefined” or “predefined rules” mentioned in the embodiments of the present application can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in devices (for example, including terminal devices and network devices), and the present application does not limit its specific implementation method. For example, predefined can refer to what is defined in the protocol. It should also be understood that in the embodiments of the present application, the “protocol” may refer to a standard protocol in the field of communications, for example, it may include LTE protocols, NR protocols, and related protocols used in future communication systems, and the present application does not limit this.

[0077] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0078] As shown in Figure 3A, during the sensing measurement setup establishment phase, the sensing initiator sends a Sensing Measurement Setup Request frame to the sensing responder. The Sensing Measurement Setup Request frame is used to request sensing measurement setup. The sensing responder then responds with a Sensing Measurement Setup Response frame. If the AP is the sensing initiator and the STA is the sensing responder, a trigger-based (TB) sensing measurement instance will be performed. If the STA is the sensing initiator and the AP is the sensing responder, a non-trigger-based (non-TB) sensing measurement instance will be performed.

[0079] It should be noted that in a TB perception measurement instance or a non-TB perception measurement instance, the end that sends the perception data frame (e.g., NDP) is the perception transmitter, and the end that receives the perception data frame is the perception receiver, where the perception data frame is used to determine the result of the perception measurement.

[0080] The frame format of the sensing measurement setup request frame is shown in Figure 3B, which includes the following fields: Category occupying 1 byte, Public Action occupying 1 byte, Dialog Token occupying 1 byte, Measurement Setup ID occupying 1 byte, and Sensing Measurement Parameters Element occupying a variable number of bytes.

[0081] The frame format of the sensing measurement parameter element is shown in Figure 3C, which includes the following fields: an element identifier (Element ID) occupying 1 byte, a length (Length) occupying 1 byte, an element identifier extension (Element ID Extension) occupying 1 byte, and sensing measurement parameters (Sensing Measurement Parameters) occupying a variable number of bytes.

[0082] The frame format of the Sensing Measurement Parameters field is shown in Figure 3D and includes the following subfields: Sensing Transmitter (1 bit), Sensing Receiver (1 bit), Sensing Measurement Report Request (1 bit), and Sensing Measurement Report Type (3 bits). The Sensing Transmitter field indicates whether the sensing responder is a sensing transmitter, and the Sensing Receiver field indicates whether the sensing responder is a sensing receiver.

[0083] It should be noted that the subfields in the perception measurement parameter field include but are not limited to the subfields shown in FIG. 3D .

[0084] In related art, the perception measurement report type subfield identifies the type of the perception measurement report requested based on a set value. If the perception initiator is the perception receiver, the perception measurement report type subfield is retained or reversed.

[0085] TB Sensing Measurement instance

[0086] TB perception measurement instances include a polling phase and one or more of the following phases: a trigger frame (TF) sounding phase, a null data packet announcement (NDPA) sounding phase, and a reporting phase.

[0087] In one example, as shown in FIG4A , the TB awareness measurement instance includes the following phases: a polling phase (polling phase), a triggered frame detection phase (TF detection phase), and a Null Data Packet Announcement (NDPA) detection phase (NDPA Sounding phase).

[0088] During the polling phase, the AP sends a Sensing Polling Trigger frame to the inquiring STA, asking whether the STA participates in the TB sensing measurement instance. The Sensing Polling Trigger frame allocates each Resource Unit (RU) to one STA. If an STA participates in the TB sensing measurement instance, it responds with a Clear-to-Send (CTS)-to-Self frame (CTS-to-self) on the allocated RU. As shown in Figure 4A, the AP sends a Sensing Polling Trigger frame to STAs 1 to 5, asking whether STAs 1 to 5 participate in the TB sensing measurement instance. STAs 1 to 4 return CTS-to-self frames to the AP, indicating that STAs 1 to 4 participate in the TB sensing measurement instance.

[0089] In the TF detection phase or the NDPA detection phase, the AP sends a sensing sounding trigger frame (Sensing Sounding Trigger frame) or a sensing NDPA frame (Sensing NDPA frame) to multiple STAs participating in the TB sensing measurement instance to perform sensing measurement. As shown in Figure 4A, in the TF detection phase, the AP sends a sensing sounding trigger frame to multiple STAs participating in the TB sensing measurement instance. The STA that receives the sensing sounding trigger frame returns a Null Data Packet (NDP) frame to the AP as the sensing sender. The AP determines the measurement information based on the NDP frame returned by the STA. In the NDPA detection phase, the AP sends a Sensing NDPA frame to multiple STAs participating in the TB sensing measurement instance, and sends an NDP frame to multiple STAs participating in the TB sensing measurement instance. The STA that receives the Sensing NDPA frame and the NDP determines the measurement information based on the received NDP frame.

[0090] As shown in Figure 4A, during the TF detection phase, the AP sends a sensing detection trigger frame. STA1 and STA2, which act as sensing transmitters among the STAs that receive the sensing detection trigger frame, return a non-NDP frame to the AP. As shown in Figure 4A, during the NDPA detection phase, the AP sends a sensing NDPA and, as a sensing transmitter, sends an NDP frame.

[0091] In some embodiments, as shown in FIG4A , the transmission interval between frames is a short interframe space (SIFS).

[0092] In the reporting phase, the AP sends a sensing reporting trigger frame (Sensing Reporting Trigger frame) to multiple STAs participating in the TB sensing measurement instance. The STAs that receive the sensing reporting trigger frame return a sensing report frame (Sensing Repor frame) to the AP, where the Sensing Repor frame carries the STA's measurement information.

[0093] This solution fails to consider the situation where a large number of STAs are participating in a TB perception measurement instance, preventing the AP from querying all STAs with a single perception poll trigger frame. Furthermore, there is no STA wakeup / sleep mechanism designed. STAs must remain awake to receive the perception poll trigger frame sent by the AP and participate in the TB perception measurement instance, which hinders STA power conservation.

[0094] The improved TB sensing measurement instance proposes the Sensing Availability Window

[0095] The Awareness Available Window (AAW) is the time period allocated to the AP and one or more STAs to participate in a TB Awareness Measurement Instance. All TB Awareness Measurement Instances occur within the AAW. A AAW includes one or more Transmission Opportunities (TXOPs), and each TXOP includes one or more TB Awareness Measurement Instances.

[0096] As shown in Figure 4B, a perception available window includes two transmission opportunities: TXOP1 and TXOP2. TXOP1 includes the first (1st) TB perception measurement instance. The first TB perception measurement instance includes the following stages: polling stage, NDPA detection stage, TF detection stage and reporting stage. In the polling stage of the first TB perception measurement instance, the value of the more trigger frame (moreTF) field in the perception polling trigger frame sent by the AP is 1, indicating that there are perception polling trigger frames to be sent next in the perception available window, that is, there are TB perception measurement instances; in TXOP2, the second (2nd) TB perception measurement instance is included. The second TB perception measurement instance includes the following stages: polling stage, TF detection stage, NDPA detection stage and reporting stage. In the polling stage of the second TB perception measurement instance, the value of the moreTF field in the perception polling trigger frame sent by the AP is 0, indicating that there are no perception polling trigger frames to be sent next in the perception available window, that is, there is no TB perception measurement instance.

[0097] In Figure 4B, one TXOP includes one TB perception measurement instance. It should be noted that one TXOP can include multiple TB perception measurement instances. As shown in Figure 4C, one TXOP includes two TB perception measurement instances: a first TB perception measurement instance and a second TB perception measurement instance. The first TB perception measurement instance includes a polling phase and a TF detection phase. During the polling phase of the first TB perception measurement instance, the value of the moreTF field in the perception polling trigger frame sent by the AP is 1. The second TB perception measurement instance includes a polling phase, an NDPA detection phase, and a reporting phase. During the polling phase of the second TB perception measurement instance, the value of the moreTF field in the perception polling trigger frame sent by the AP is 0.

[0098] When there are a large number of STAs participating in a TB sensing measurement instance, the AP cannot query all STAs using one sensing polling trigger frame. The following solutions are available:

[0099] If the AP does not poll all STAs indicated to be polled in the perception available window using a perception poll trigger frame, the AP will attempt to schedule one or more additional TB perception measurement instances, where each TB perception measurement instance starts based on a polling phase in the same perception available window. The AP will indicate additional perception measurement instances by setting the moreTF subfield of the Common Info field in the perception poll trigger frame to 1 and the target address field (RA field) to a broadcast address. Additional perception measurement instances may occur within the same transmission opportunity in the same perception available window, or in different transmission opportunities within the same perception available window. If the AP sets the value of moreTF in the previous TB perception measurement instance to 1 and there is no additional perception measurement instance in the perception available window, the AP will set the moreTF in the information field to 0 and the receiver address (RA) of the next perception poll trigger frame to a broadcast address. If a STA receives a perception polling trigger frame whose user information field does not include the STA's address, the STA may enter a doze state or a sleep state (doze) if there are no other conditions requiring the STA to remain awake.

[0100] The improved TB perception measurement instance addresses the issue of the AP being unable to query all STAs using a single perception poll trigger frame when a large number of STAs participate in a TB perception measurement instance. Instead, the AP proposes using multiple perception poll trigger frames within the perception available window to query these STAs, and then performing TB perception measurement instances in groups. However, in this scheme, STAs not queried by the perception poll trigger frame must remain awake throughout the perception available window. They can only go into sleep mode if they confirm that no perception poll trigger frames will be forthcoming by setting More TF = 0. Consequently, while some STAs perform TB perception measurement instances within the perception available window, those not queried by the perception poll trigger frame remain awake, consuming additional power. Unqueried STAs can be understood as STAs that receive a perception poll trigger frame but whose user information field does not include their address.

[0101] Non-TB Sensing Measurement instance

[0102] Figure 4D shows a typical non-TB sensing measurement example process: As the sensing initiator, the station initiates a non-TB sensing measurement instance by sending a sensing NDPA frame to the AP. After a SIFS, the station sends an initiator-to-responder (I2R) NDP to the AP. Upon receiving the (I2R) NDP correctly, the AP sends a responder-to-initiator (R2I) NDP to the STA after a SIFS.

[0103] If the station is only a sensing transmitter, the sensing NDPA frame configures the R2I NDP to include one Long Training Field (LTF) symbol so that the R2I NDP has the minimum length. If the station is only a sensing receiver, the sensing NDPA frame configures the I2R NDP to include one LTF symbol so that the I2R NDP has the minimum length.

[0104] During the Sensing Measurement Setup Termination procedure for a non-TB sensing measurement instance, if a STA wishes to terminate the non-TB sensing measurement instance, it can directly send a Sensing Measurement Setup Termination frame to the AP. However, in a non-TB sensing measurement instance, there is no Sensing Available Window. Outside of the Sensing Available Window, the STA may be in sleep mode or performing data communication. Therefore, if the AP directly sends a Sensing Measurement Setup Termination frame to the STA to terminate the non-TB sensing measurement instance, the STA may not receive the Sensing Measurement Setup Termination frame sent by the AP.

The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application.

[0107] S501A, the first node receives a first frame sent by the second node, where the first frame is used to request perception measurement settings, and the first frame carries first indication information, where the first indication information is used to indicate the type of perception measurement report. If the first node is not a perception receiving end and / or the second node is not a perception sending end, the first indication information is set to be retained.

[0108] FIG5B is a wireless communication method provided in an embodiment of the present application, which is applied to a first node. As shown in FIG5B , the method includes:

[0109] S501B, the first frame sent by the second node to the first node, the first frame is used to request perception measurement setting, the first frame carries first indication information, the first indication information is used to indicate the type of perception measurement report, if the first node is not a perception receiving end and / or the second node is not a perception sending end, then the first indication information is set to be retained.

[0110] FIG5C is a wireless communication method provided in an embodiment of the present application, which is applied to a second node. As shown in FIG5C , the method includes:

[0111] S501C: The second node sends a first frame to the first node.

[0112] The first frame is used to request perception measurement settings, and the first frame carries first indication information, and the first indication information is used to indicate the type of perception measurement report. If the first node is not a perception receiving end and / or the second node is not a perception sending end, the first indication information is set to be retained.

[0113] Next, the wireless communication method shown in FIG. 5A , FIG. 5B or FIG. 5C is further described.

[0114] The first frame is used to request perception measurement settings, and the second node sends the first frame to the first node, then the second node is the perception initiator, and the first node is the perception responder.

[0115] Optionally, the first frame is a perception measurement setting request frame.

[0116] The first frame carries first indication information for indicating the type of the perception measurement report. Different values ​​of the first indication information indicate different types of perception measurement reports. Optionally, if the value of the first indication information is 0, it indicates channel state information (CSI); if the value of the first indication information is 1 to 7, the perception measurement report type is reserved.

[0117] Taking the first frame as a perception measurement setting request frame as an example, the first frame includes a perception measurement parameter element field, the perception measurement parameter element field includes a perception measurement report type field, and the first indication information is located in the perception measurement report type field.

[0118] In an embodiment of the present application, in a perception measurement instance in which a first node and a second node participate, the role of the end sending the perception data frame (e.g., NDP) is the perception sending end, and the role of the end receiving the perception data frame is the perception receiving end, wherein the perception data frame is used to determine the result of the perception measurement.

[0119] In the embodiment of the present application, the roles of the first node and the second node can be one of a perception receiving end and a perception sending end respectively, or can be both a perception receiving end and a perception sending end.

[0120] The roles of the first node and the second node in the perception measurement instance include the following:

[0121] Case A1: the first node is a sensing sender and not a sensing receiver, and the second node is a sensing receiver and not a sensing sender;

[0122] Case A2: The first node is a sensing receiver and not a sensing transmitter, and the second node is a sensing transmitter and not a sensing receiver;

[0123] Case A3: The first node is a sensing transmitter and a sensing receiver, and the second node is a sensing receiver and a sensing transmitter.

[0124] For case A1, the first node is only a sensing transmitter, and the second node is only a sensing receiver.

[0125] For case A2, the first node is only a sensing receiver, and the second node is only a sensing transmitter.

[0126] In the embodiment of the present application, if the first node is not a perception receiving end and / or the second node is not a perception sending end, the first indication information of the first frame is set to be retained. It is understandable that if the perception responding end is not a perception receiving end and / or the perception initiating end is not a perception sending end, the first indication information is set to be retained.

[0127] Whether the first indication information is retained may be determined based only on the first node or the second node, or may be determined based on the first node and the second node. In an embodiment of the present application, when the perception responding end is not the perception receiving end and / or the perception initiating end is not the perception sending end, the first indication information indicating the perception measurement report type is set to be retained, so that in a scenario where the perception responding end is not the perception receiving end and / or the perception initiating end is not the perception sending end, the first indication information does not carry valid configuration information, thereby avoiding the first indication information from carrying unnecessary configuration information.

[0128] In some embodiments, the first node is a perception sending end, and / or the second node is a perception receiving end.

[0129] It can be understood that at this time, the roles of the first node and the second node belong to situation A2.

[0130] If the perception responding end is not a perception receiving end but a perception sending end, and / or the perception initiating end is not a perception sending end but a perception receiving end, the first indication information is set to be retained.

[0131] In some embodiments, the first frame further carries at least one of the following information:

[0132] Second indication information, where the second indication information is used to indicate whether the first node is a perception sending end;

[0133] The third indication information is used to indicate whether the first node is a perception receiving end.

[0134] Optionally, the second indication information indicates whether the first node, i.e., the sensing responder, is a sensing sender based on different values. In one example, if the value of the second indication information is 1, it indicates that the sensing responder is a sensing sender; otherwise, the value of the second indication information is 0.

[0135] Optionally, the third indication information indicates whether the first node, i.e., the sensing responding end, is a sensing receiving end based on different values. In one example, when the value of the third indication information is 1, it indicates that the sensing responding end is a sensing receiving end, otherwise the value of the second indication information is 0.

[0136] It is understandable that if the value of the third indication information is 0, the first indication information is set to be retained.

[0137] Taking the first frame as an example, in which the perception measurement setting request frame is a first indication information, the second indication information, and the third indication information are located in the perception measurement parameter element field of the perception measurement setting request frame. The first indication information, the second indication information, and the third indication information are located in the perception measurement parameter field of the perception measurement parameter element field and are located in different subfields of the perception measurement parameter field. Optionally, the second indication information is located in the perception transmitting terminal field of the first frame. Optionally, the third indication information is located in the perception receiving terminal field of the first frame.

[0138] In the embodiment of the present application, the first node is one of a station (STA) and an AP, and the second node is the other of the station and the AP. The first node and the second node are based on different device types and include the following two scenarios:

[0139] Scenario 1: The first node is the first site, and the second node is the access point;

[0140] Scenario 2: The second node is an access point, and the first node is a first site.

[0141] The first station is any station associated with or not associated with the AP.

[0142] Below, scenario one and scenario two are described respectively.

[0143] Scene 1

[0144] If the first node is a first station and the second node is an access point, the first station and the access point are used to set a trigger-based TB awareness measurement instance and / or participate in a TB awareness measurement instance.

[0145] In scenario 1, the perception measurement instance between the first node and the second node is a TB perception measurement instance, and the perception measurement setting performed based on the first frame is a perception measurement setting for the TB perception measurement instance.

[0146] The roles of the first site and the second node can be any one of Cases 1 to 3 above.

[0147] In some embodiments, the first frame further carries at least one of the following information:

[0148] Fourth indication information, where the fourth indication information is used to indicate a perception available window;

[0149] The fifth indication information is used to indicate whether the first site requires the access point to send a second frame to the first site, and the second frame is used to inquire at least one site whether to participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity, and the first transmission opportunity is any transmission opportunity in the perception available window.

[0150] In this embodiment of the present application, the perception availability window is the time period for participating in a TB perception measurement instance. All TB perception measurement instances occur within the perception availability window. A perception availability window includes at least one transmission opportunity, and a transmission opportunity includes at least one TB perception measurement instance. The first transmission opportunity is any transmission opportunity within the perception availability window indicated by the fourth indication information.

[0151] In one example, if the first node is a first station and the second node is an access point, the frame format of the first frame is as shown in Figures 3A and 3B, and the frame structure of the perception measurement parameter field is as shown in Figure 6A, including the following subfields: perception transmitter, perception receiver, perception measurement report request, perception measurement report type, perception available window information, request polling, and reservation. Among them, the perception transmitter field carries the second indication information, the perception receiver field carries the third indication information, the perception measurement report type subfield carries the first indication information, the perception available window information subfield carries the fourth indication information, and the request polling subfield carries the fifth indication information. Optionally, the perception measurement report type subfield occupies x bits, the request polling subfield occupies 1 bit, and the reservation subfield occupies y bits. The sum of the lengths of x and y makes the length of the perception measurement parameter subfield meet the first length. Optionally, the first length is an integer multiple of 8 bits.

[0152] Scene 2

[0153] If the first node is an access point and the second node is a first station, the first station and the access point are configured to set a non-trigger-based non-TB awareness measurement instance and / or participate in a non-TB awareness measurement instance.

[0154] In scenario 2, the perception measurement instance between the first node and the second node is a non-TB perception measurement instance, and the perception measurement setting performed based on the first frame is a perception measurement setting for the non-TB perception measurement instance.

[0155] The roles of the first site and the second node can be any one of Cases 1 to 3 above.

[0156] For a non-TB perception measurement instance, the first frame does not carry information related to the TB perception measurement instance, such as the fourth indication information and the fifth indication information.

[0157] In one example, the first node is a first station and the second node is an access point. The frame format of the first frame is as shown in Figures 3A and 3B, and the frame structure of the perception measurement parameter field is as shown in Figure 6B, including the following subfields: Perception Transmitter, Perception Receiver, and Reserved. The Perception Transmitter field carries the second indication information, the Perception Receiver field carries the third indication information, and the Perception Measurement Report Type subfield carries the first indication information.

[0158] An embodiment of the present application provides a wireless communication method, which is applied to a first station serving as a sensing responder, as shown in FIG7A , including:

[0159] S701A. The first station receives a second frame sent by the access point, where the second frame is used to inquire at least one station whether to participate in perception measurement and / or perception reporting of a TB perception measurement instance of a first transmission opportunity; the at least one station constitutes a first station set, and the stations in the first station set that participate in perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity constitute a second station set;

[0160] S702A: If the first site is not included in the second site set, the first site enters a dormant state.

[0161] An embodiment of the present application provides a wireless communication method, which is applied to an access point serving as a sensing initiator, as shown in FIG7B , including:

[0162] S701B, the access point sends a second frame to the first site, the second frame is used to inquire at least one site whether to participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity; the at least one site constitutes a first site set, and the sites in the first site set that participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity constitute a second site set; if the first site is not included in the second site set, the second frame is also used to trigger the first site to enter a sleep state.

[0163] An embodiment of the present application provides a wireless communication method, which is applied to a wireless communication system. The wireless communication system includes: an access point as a perception initiator and a first station as a perception responder, as shown in FIG7C , including:

[0164] S701C: The access point sends a second frame to the first station.

[0165] The second frame is used to inquire at least one station whether to participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity; the at least one station constitutes a first station set, and the stations in the first station set that participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity constitute a second station set;

[0166] S702C: If the first site is not included in the second site set, the first site enters a dormant state.

[0167] It is understandable that the wireless communication method shown in Figures 7A, 7B, and 7C can be implemented in combination with scenario 1 in the wireless communication method shown in Figures 5A, 5B, and 5C, or can be implemented independently of the wireless communication method shown in Figures 5A, 5B, and 5C.

[0168] The wireless communication method shown in FIG. 7A , FIG. 7B or FIG. 7C is described below.

[0169] The second frame is used to inquire at least one station whether to participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity.

[0170] Optionally, the second frame is a broadcast frame or a multicast frame, and the RA address of the second frame is a broadcast address or a multicast address. The user information list information of the second frame indicates at least one station, so as to inquire at least one station whether to participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity.

[0171] In one example, the second frame is a perception polling trigger frame.

[0172] The access point sends a second frame, and multiple stations including the first station receive the second frame. Here, the first station is any station that receives the second frame.

[0173] After receiving the second frame, the first station determines, based on the second frame, whether the first station is included in the at least one station queried by the access point via the second frame. If the at least one station includes the first station, this indicates that the access point has queried the first station whether to participate in the perception measurement and / or perception reporting of the TB perception measurement instance in the first transmission opportunity. The first station determines to participate in the perception measurement and / or perception reporting of the TB perception measurement instance in the first transmission opportunity and returns a third frame to the access point. The third frame is used to instruct the first station to participate in the perception measurement and / or perception reporting of the TB perception measurement instance in the first transmission opportunity. If the first station does not participate in the perception measurement and / or perception reporting of the TB perception measurement instance in the first transmission opportunity, the third frame is not returned to the access point.

[0174] In an embodiment of the present application, at least one site queried by the access point through the second frame constitutes a first site set, and the sites in the first site set that participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity constitute a second site set.

[0175] In one example, the perception initiator is AP, and the perception responders include: STA1, STA2, STA3 and STA4. AP broadcasts the second frame, and STA1, STA2, STA3 and STA4 all listen to the second frame. If the second frame is used to ask STA1, STA2, STA3 whether to participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity, the first site set is {STA1, STA2, STA3}. If STA1 and STA2 return the third frame to the access point respectively, the second site set is {STA1, STA2}.

[0176] In the embodiment of the present application, when the first station receives the second frame and determines that it is not included in the second station set, it enters a doze state.

[0177] In one example, the perception initiator is AP, and the perception responder includes: STA1, STA2, STA3 and STA4. The first site set is {STA1, STA2, STA3}, and the second site set is {STA1, STA2}. For STA3, if it is not included in the second site set, it enters a sleep state. For STA4, if it is not included in the second site set, it enters a sleep state.

[0178] In the wireless communication method provided in the embodiment of the present application, the station enters a sleep state when it receives a second frame that asks whether to participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity, and determines based on the second frame that it does not participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity. It does not need to determine whether there is still a TB perception measurement instance in the first transmission opportunity, nor does it wait until there is no TB perception measurement instance in the first transmission opportunity before entering the sleep state. It enters the sleep state when it determines that it does not participate in the TB perception measurement instance of the first transmission opportunity, thereby saving power.

[0179] In some embodiments, the first site is not included in the second set of sites, including one of the following:

[0180] The first site is not included in the first site set;

[0181] The first station is included in the first station set and does not return a third frame to the access point, where the third frame is used to indicate the perception measurement and / or perception reporting of the TB perception measurement instance participating in the first transmission opportunity.

[0182] If the first site is not included in the first site set, the at least one site queried by the second frame does not include the first site, indicating that the access point has not been asked whether the first site participates in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity.

[0183] If the first site is included in the first site set and does not return the third frame to the access point, it indicates that the first site is asked by the access point whether to participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity, and the first site does not participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity.

[0184] Optionally, the third frame is a Clear to Send (CTS-to-self) frame.

[0185] In an embodiment of the present application, the first site enters a dormant state when it is not asked whether to participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity, or is asked whether to participate and does not participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity.

[0186] In some embodiments, the first site is not included in the first set of sites, including:

[0187] The first information carried by the second frame does not include the first identifier of the first site, and the first information includes the first identifier of each site in the first site set.

[0188] In some embodiments, the first site is included in the first site set, including:

[0189] The first information carried by the second frame includes the first identifier of the first site, and the first information includes the first identifier of each site in the first site set.

[0190] The first information is used to indicate at least one station queried by the access point.

[0191] The access point includes the first identifier of each station in the at least one station to be queried in the first information and sends the first information to the first station by carrying it in the second frame.

[0192] After receiving the second frame, the first station determines whether it is included in the first station set based on the first information carried in the second frame, that is, determines whether it is asked to participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity. If the first station determines that the first message of the second frame does not include its first identifier, it determines that it is not included in the first station set, that is, it determines that the access point has not asked it whether to participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity; if the first station determines that the first message of the second frame includes its first identifier, it determines that it is included in the first station set, that is, it determines that the access point has asked it whether to participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity.

[0193] Optionally, the first information is located in a user information list field of the second frame, the user information list field includes at least one user information field, and different user information fields include first identifiers of different sites in the first site set.

[0194] The different user information fields (User Info fields) included in the user information list (User Info List) field are for different sites, and each user information field includes a first identifier of the corresponding site.

[0195] Optionally, the first identifier includes at least one of the following:

[0196] Association identifier AID;

[0197] The device identifier USID is not associated.

[0198] The AID is an identifier assigned when the corresponding station is associated with an access point, and the USID is an identifier assigned when the corresponding station is not associated with an access point.

[0199] In some embodiments, the first station enters the sleep state, comprising: the first station enters the sleep state immediately or after a first time delay after receiving the second frame.

[0200] Optionally, the first duration includes at least one of the following: SIFS, Point (coordination function) Interframe Space (PIFS), Distributed (coordination function) Interframe Space (DIFS) or other durations.

[0201] In the embodiment of the present application, the first duration may be a fixed duration, may be negotiated between the first station and the access point, or may be indicated by the access point. The embodiment of the present application does not impose any limitation on the size and determination method of the first duration.

[0202] In some embodiments, the condition for the first station to enter the dormant state includes: the first station does not have a first condition, and the first condition is used to require the first station to remain awake.

[0203] In the embodiment of the present application, whether the first site is included in the second site set and the priority of the first condition are not limited in any way.

[0204] Taking the example that the priority of whether the first site is included in the second site set is higher than the priority of the first condition, the first site is determined not to be included in the second site set, then it is judged whether the first condition exists, if the first condition exists, the first site remains awake based on the first condition, if the first condition does not exist, the first site enters a sleep state.

[0205] Taking the example where the priority of whether the first site is included in the second site set is lower than the priority of the first condition, the first site determines whether it meets the first condition; if the first condition meets the first condition, it remains awake based on the first condition and does not determine whether it is included in the second site set; if the first condition does not meet the first condition, it determines whether it is included in the second site set based on the trigger of the received second frame, and if it is not included in the second site set, it enters the sleep state.

[0206] In some embodiments, in a case where the first station enters a sleep state, the first station is in the sleep state during the first transmission opportunity.

[0207] Here, the first transmission opportunity includes one or more TB perception measurement instances. If the first station enters the dormant state, it does not participate in the perception measurement and / or perception reporting of all TB perception measurement instances in the first transmission opportunity and remains in the dormant state in the first transmission opportunity.

[0208] In some embodiments, the method further includes: the first station exiting the sleep state at a first moment, where the first moment is a moment when the first transmission opportunity ends.

[0209] If the first station determines not to participate in the perception measurement and / or perception reporting of the perception measurement instance in the first transmission opportunity, the first station stays in the dormant state in the first transmission opportunity until the end of the first transmission opportunity.

[0210] Here, the perceived available window includes one or more transmission opportunities, and the first transmission opportunity is any transmission opportunity in the perceived available window. The sleep state of the first station is based on the transmission opportunity as a time reference, and the states of different transmission opportunities are independent.

[0211] For example, as shown in FIG8 , the perception available window includes two transmission opportunities: transmission opportunity 1 and transmission opportunity 2. For transmission opportunity 1, the first station is not included in the second station set of transmission opportunity 1, then the first station enters the sleep state at time T1 in transmission opportunity 1 and exits the sleep state at the end time T2 of transmission opportunity 1. For transmission opportunity 2, the first station is included in the second station set of transmission opportunity 2, then the first station does not enter the sleep state in transmission opportunity 2.

[0212] In some embodiments, the second frame carries second information, and the second information is used to indicate the duration of the first transmission opportunity.

[0213] Optionally, the second information is located in a duration field (Duration / ID field) included in the second frame.

[0214] In some embodiments, the first transmission opportunity is any transmission opportunity in a first perceived available window, and the first station is allocated to the first perceived available window.

[0215] Here, the perception availability window to which the first transmission opportunity belongs is referred to as the first perception availability window. Stations in the first station set are assigned to the first perception availability window. For any transmission opportunity in the first perception availability window, the access point transmits a second frame during the transmission opportunity. Using the second frame, the access point polls the stations assigned to the first perception availability window to determine whether they are participating in the perception measurement and / or perception reporting of the TB perception measurement instance in the transmission opportunity.

[0216] In the embodiment of the present application, even if the first station is not included in the first station set, the first station is still a station assigned to the first perception available window and can participate in the perception measurement instance in the first perception available window.

[0217] In this embodiment of the present application, the first transmission opportunity includes at least one TB-aware measurement instance.

[0218] Optionally, the second frame is sent during a polling phase of a first TB-aware measurement instance of the first transmission opportunity.

[0219] In one example, the first transmission opportunity includes three TB perception measurement instances: TB perception measurement instance 1, TB perception measurement instance 2, and TB perception measurement instance 3. The access point sends the second frame during the polling phase of TB perception measurement instance 1. When the first station determines that it is not included in the second station set, it enters a dormant state and does not participate in the perception measurement and / or perception reporting of TB perception measurement instance 1, TB perception measurement instance 2, and TB perception measurement instance 3.

[0220] For the first TB perception measurement instance of the first transmission opportunity, the sites participating in the perception measurement and / or perception reporting of the first TB perception measurement instance of the first transmission opportunity are sites included in the third site set, and the third site set is a subset of the second site set.

[0221] It is understandable that the second site set includes sites that participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity. When the first transmission opportunity includes one or more TB perception measurement instances, for the first TB perception measurement instance, the sites participating in the TB perception measurement instance include all or part of the sites in the second site set, that is, the sites participating in the TB perception measurement instance are the third site set, and the third site set is a subset of the second site set.

[0222] In the embodiment of the present application, in the first sensing measurement instance of the first transmission opportunity, the third site set is a subset of the first site set, and the third sites are combined into a subset of the second site set.

[0223] In one example, the second set of stations is {STA1, STA2, STA3, and STA4}, and the third set of stations is {STA1, STA2, STA3, STA4}.

[0224] In one example, the second set of stations is {STA1, STA2, STA3, and STA4}, and the third set of stations is {STA1, STA2, STA3}.

[0225] Optionally, if the first transmission opportunity includes at least two TB perception measurement instances, the first TB perception measurement instance of the first transmission opportunity includes a polling phase or does not include a polling phase, and the first TB perception measurement instance is any TB perception measurement instance located after the first TB perception measurement instance of the first transmission opportunity.

[0226] For any TB-awareness measurement instance after the first TB-awareness measurement instance of the first transmission opportunity, the TB-awareness measurement instance includes a polling phase or does not include a polling phase.

[0227] Optionally, each TB-awareness measurement instance after the first TB-awareness measurement instance of the first transmission opportunity includes or does not include a polling phase.

[0228] In an embodiment of the present application, when the polling phase of the first TB perception measurement instance of the first transmission opportunity determines the site participating in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity, the TB perception measurement instance after the first TB perception measurement instance includes a polling phase, and can be designed according to the process in which the TB perception measurement instance includes a polling phase, thereby reducing the changes in the process of multiple TB perception measurement instances.

[0229] In an embodiment of the present application, when the sites participating in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity are determined during the polling phase of the first TB perception measurement instance of the first transmission opportunity, the polling phase is not included in the TB perception measurement instances after the first TB perception measurement instance, which can reduce the process of subsequent TB perception measurement instances and thus simplify the process of the TB perception measurement instances.

[0230] Taking the first TB perception measurement instance not including the polling phase as an example, the sites participating in the perception measurement and / or perception reporting of the first TB perception measurement instance are the sites included in the fourth site set, and the fourth site set is a subset of the second site set.

[0231] In one example, the second set of stations is {STA1, STA2, STA3, and STA4}, and the fourth set of stations is {STA1, STA2, STA3, STA4}.

[0232] In one example, the second set of stations is {STA1, STA2, STA3, and STA4}, and the fourth set of stations is {STA1, STA3}.

[0233] In the embodiment of the present application, the fourth site sets corresponding to different first perception measurement instances may be the same or different.

[0234] If the first transmission opportunity includes three TB perception measurement instances, and the second site set is {STA1, STA2, STA3 and STA4}, the sites participating in the perception measurement and / or perception reporting of the first perception measurement instance include {STA1, STA2}, the sites participating in the perception measurement and / or perception reporting of the second perception measurement instance include {STA1, STA2, STA3}, and the sites participating in the perception measurement and / or perception reporting of the third perception measurement instance include {STA1, STA2, STA4}.

[0235] Taking the first TB perception measurement instance including a polling phase as an example, the sites polled in the polling phase of the first TB perception measurement instance are sites included in the fifth site set, and the fifth site set is a subset of the second site set.

[0236] In one example, the second set of stations is {STA1, STA2, STA3, and STA4}, and the fifth set of stations is {STA1, STA2, STA3, STA4}.

[0237] In one example, the second set of stations is {STA1, STA2, STA3, and STA4}, and the fifth set of stations is {STA1, STA2, STA3}.

[0238] In the embodiment of the present application, the fifth site sets corresponding to different first perception measurement instances may be the same or different.

[0239] If the first transmission opportunity includes three TB perception measurement instances, and the second site set is {STA1, STA2, STA3, and STA4}, the sites participating in the polling phase of the second perception measurement instance include {STA1, STA2, STA3}, and the sites participating in the polling phase of the third perception measurement instance include {STA1, STA2, STA4}.

[0240] In the case where the first TB perception measurement instance includes a polling phase, the sites participating in the perception measurement and / or perception reporting of the first TB perception measurement instance are sites included in a sixth site set, and the sixth site set is a subset of the fifth site set.

[0241] In one example, the fifth set of stations is {STA1, STA2, STA3}, and the sixth set of stations is {STA1, STA2, STA3}.

[0242] In one example, the fifth station set is {STA1, STA2, STA3}, and the sixth station set is {STA1, STA2}.

[0243] In the embodiment of the present application, the sixth site sets corresponding to different first perception measurement instances may be the same or different.

[0244] It can be understood that the third site set, the fourth site set and the fifth site set are all subsets of the second site set, and the third site set, the fourth site set and the fifth site set are independent.

[0245] In the embodiment of the present application, the participating in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity includes: participating in the perception measurement and / or perception reporting of at least one TB perception measurement instance in the first transmission opportunity.

[0246] It is understandable that if a site participates in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity, then it participates in the perception measurement and / or perception reporting of at least one TB perception measurement instance in the first transmission opportunity. At this time, if a site does not participate in the perception measurement and / or perception reporting of the TB perception measurement instance of the first transmission opportunity, then it does not participate in the perception measurement and / or perception reporting of any TB perception measurement instance in the first transmission opportunity.

[0247] Optionally, the perception measurement of the TB perception measurement instance includes at least one of the following stages:

[0248] No data declared in the NDPA detection phase;

[0249] Trigger frame TF detection phase.

[0250] Optionally, the perception reporting of the TB perception measurement instance includes: a reporting stage.

[0251] It is understandable that a TB perception measurement instance may include at least one of the following stages: NDPA detection stage, TF detection stage, and reporting stage.

[0252] Different TB-aware measurement instances include independent phases.

[0253] In some embodiments, the TF detection phase includes at least one sensing measurement operation, where the sensing measurement operation includes the access point performing frame interaction with a second station, where the second station belongs to the second station set.

[0254] The sensing measurement operation may be understood as a TF detection sub-phase. A TF phase may include one or more TF detection sub-phases.

[0255] For a TB perception measurement instance, when the TB perception measurement instance includes a TF phase, the second site is a site participating in the TF phase.

[0256] In the TF detection phase, the access point performs the following processing: the access point sends a perception detection trigger frame to the second station; the access point receives a null data packet NDP frame sent by the second station.

[0257] If the first station is the second station, the method further includes:

[0258] The first station receives the perception detection trigger frame sent by the access point;

[0259] The first station sends a Null Data Packet (NDP) frame to the access point.

[0260] The first station being the second station can be understood as: the first station is included in the second station set, at this time, the first station does not enter sleep during the first transmission opportunity, and the first station participates in the TF detection phase included in the TB measurement instance of the first transmission opportunity.

[0261] During the TF detection phase of the TB measurement instance in the first transmission opportunity, the first station receives a perception detection trigger frame sent by the access point, and returns an NDP frame to the access point to complete a TF detection sub-phase, that is, a perception measurement operation.

[0262] Optionally, the NDP frame is sent at a second time duration after the sensing detection trigger frame is received. Optionally, the second time duration is SIFS.

[0263] In the TF detection phase, the second stations in different sensing measurement operations are different.

[0264] It can be understood that in different TF detection sub-stages, the AP and different second sites perform frame interactions.

[0265] In one example, three stations (STA1, STA2, and STA3) participate in the TF detection phase of a TB perception measurement instance. In the TF detection phase, the access point sends perception detection trigger frames to STA1, STA2, and STA3 respectively. After receiving the perception detection trigger frames, STA1, STA2, and STA3 respectively return NDP frames to the access point.

[0266] In an embodiment of the present application, in the TF detection phase, the access point may send a perception detection trigger frame to another second station after receiving an NDP frame sent by a second station.

[0267] An embodiment of the present application provides a wireless communication method, which is applied to an access point serving as a sensing responder, as shown in FIG9A , including:

[0268] S901A: The access point sends an NDP frame to the first station, where the NDP frame can be used to indicate termination of perception measurement settings.

[0269] An embodiment of the present application provides a wireless communication method, which is applied to a first station serving as a sensing initiator, as shown in FIG9B , including:

[0270] S901B. The first station receives an NDP frame sent by the access point, where the NDP frame can be used to indicate the termination of perception measurement settings.

[0271] An embodiment of the present application provides a wireless communication method, which is applied to a wireless communication system. The wireless communication system includes: an access point as a perception responder and a first station as a perception initiator, as shown in FIG9C , including:

[0272] S901C. The first station receives the NDP frame sent by the access point.

[0273] The NDP frame may be used to indicate termination of awareness measurement settings.

[0274] In an embodiment of the present application, the access point serving as the perception responding end and the first site serving as the perception initiating end can effectively trigger the termination of the perception measurement setting based on the NDP frame in a non-TB perception measurement instance, thereby realizing the termination of the triggered perception measurement setting in the perception responding end, and ensuring that the first site serving as the perception initiating end can receive the request for termination of the perception measurement setting sent by the access point.

[0275] It is understandable that the wireless communication method shown in Figures 9A, 9B, and 9C can be implemented in combination with scenario 2 in the wireless communication method shown in Figures 5A, 5B, and 5C, or can be implemented independently of the wireless communication method shown in Figures 5A, 5B, and 5C.

[0276] When the wireless communication method shown in FIG9A , FIG9B , and FIG9C is implemented independently from the wireless communication method shown in FIG5A , FIG5B , and FIG5C , the perception responding end may be one or both of the perception receiving end and the perception sending end.

[0277] If the first site is only a perception transmitter and / or the access point is only a perception receiver, the NDP frame including a first number of long training field LTF symbols is used to indicate the termination of the perception measurement setting, and the NDP frame including a second number of LTF symbols is not used to indicate the termination of the perception measurement setting, and the first number is different from the second number.

[0278] It is understandable that, in the case where the first site is only a perception transmitter and / or the access point is only a perception receiver, if the NDP sent by the access point to the first site includes a first number of LTF symbols, then the NDP frame is used to indicate the termination of the perception measurement setting; if the NDP sent by the access point to the first site includes a second number of LTF symbols, then the NDP frame is not used to indicate the termination of the perception measurement setting.

[0279] Optionally, the second number is configured in a fourth frame, and the fourth frame includes an Aware NDPA frame sent by the first station to the access point.

[0280] Optionally, the second number is 1, and the first number is 2, 4, 6, 8, etc., which is different from 1.

[0281] If the first site is only a perception receiver and / or the access point is only a perception transmitter, the NDP frame including a third number of LTF symbols is used to indicate the termination of the perception measurement setting, and the NDP frame including a fourth number of LTF symbols is used for perception measurement, and the third number is different from the fourth number.

[0282] It is understandable that, in the case where the first site is only a perception receiver and / or the access point is only a perception transmitter, if the NDP sent by the access point to the first site includes a third number of LTF symbols, then the NDP frame is used to indicate the termination of the perception measurement setting; if the NDP sent by the access point to the first site includes a fourth number of LTF symbols, then the NDP frame is not used for perception measurement.

[0283] Optionally, the fourth number is configured in a fourth frame, and the fourth frame includes an awareness NDPA frame sent by the first station to the access point.

[0284] In some embodiments, the fourth number is N, and the third number is N+1 or N-1.

[0285] It can be understood that N is a positive number greater than 1.

[0286] Optionally, if N is 8, the fourth number is 8, and the value of the third number includes but is not limited to 7 and 9.

[0287] Taking N as 8 as an example, the third number may also be 2, 4, 6, 7, 9, or other numbers other than 8.

[0288] In one example, the first site is only a perception transmitter, the access point is only a perception receiver, the first quantity is 4, and the second quantity is 1. In a non-TB perception measurement instance, if the access point wants to terminate the perception measurement setting, it sends an NDP frame containing 4 LTF symbols to the first site to indicate the termination of the perception measurement setting. After the first site receives the NDP frame containing 4 LTF symbols, it determines that the access point wants to terminate the perception measurement setting.

[0289] In one example, the first site is only a perception receiver, the access point is only a perception transmitter, the third quantity is 6, and the fourth quantity is 8. In a non-TB perception measurement instance, if the access point wants to terminate the perception measurement setting, it sends an NDP frame containing 6 LTF symbols to the first site to indicate the termination of the perception measurement setting. After the first site receives the NDP frame containing 4 LTF symbols, it determines that the access point wants to terminate the perception measurement setting.

[0290] It is understandable that when the perception measurement setting is not terminated, if the first site is only a perception transmitter and the access point is only a perception receiver, in a non-TB perception measurement instance, the first site sends an NDP frame including a fourth number of LTF symbols to the access point, and the access point receives the NDP frame including the fourth number of LTF symbols, and sends an NDP frame including the second number of LTF symbols to the first site.

[0291] It is understandable that when the perception measurement setting is not terminated, if the first site is only a perception receiver and the access point is only a perception transmitter, in a non-TB perception measurement instance, the first site sends an NDP frame including a second number of LTF symbols to the access point, and the access point receives the NDP frame including the second number of LTF symbols, and sends an NDP frame including a fourth number of LTF symbols to the first site.

[0292] The device control method provided in the embodiment of the present application is further described below.

[0293] For perceptual measurement settings

[0294] During the sensing measurement phase, the sensing initiator sends a Sensing Measurement Setup Request frame to the sensing responder, and the sensing responder replies with a Sensing Measurement Setup Response frame. If the AP is the sensing initiator and the STA is the sensing responder, a TB measurement instance is performed; if the STA is the sensing initiator and the AP is the sensing responder, a non-TB measurement instance is performed.

[0295] If the sensing initiator is a sensing receiver and not a sensing transmitter, the Sensing Measurement Report Type subfield in the Sensing Measurement Setup Request frame is set to reserved. If the sensing responder is not a sensing receiver and is a sensing transmitter, the Sensing Measurement Report Type subfield in the Sensing Measurement Setup Request frame is set to reserved.

[0296] TB perception measurement example

[0297] In the wireless communication method provided in the embodiments of the present application, the first polling trigger frame of each transmission opportunity (TXOP) within the sensing available window polls all STAs to be sensed and measured in the current TXOP. STAs that are not polled can remain dormant until the end of the current TXOP. This provides STAs with more sleep opportunities and saves device power.

[0298] In the wireless communication method provided in an embodiment of the present application, the sleep rule of the STA is as follows: the AP queries / triggers all STAs participating in the TB perception measurement instance of the TXOP through a perception polling trigger frame during the polling phase of the first TB perception measurement instance of each TXOP in the perception available window. If a STA receives a perception polling trigger frame sent by the AP during the polling phase of the first TB perception measurement instance of a TXOP and finds that the perception polling trigger frame does not indicate the AID / USID of the STA, if there are no other conditions (for example, the STA does not need to be polled) requiring the STA to remain awake, the STA enters sleep immediately or after a delay, and sleeps until the end of the current TXOP. If there is a next TXOP, the STA enters the awake state and continues to receive the perception polling trigger frame sent by the AP during the polling phase of the first TB perception measurement instance of the next TXOP. Repeat the above operation. In addition, the More TF field in the perception polling trigger frame is used to indicate whether there are more perception polling trigger frames to be sent in the current perception available window, and is not used as an indication of whether the STA has entered the sleep state.

[0299] The wireless communication method provided in the embodiments of the present application can be implemented as but not limited to the following embodiments 1 to 3.

[0300] Example 1: One TXOP has only one TB perception measurement instance

[0301] As shown in Figure 10, assume that STA 1, STA 2 and STA 3 are assigned to the perception available window, and the perception available window includes two TXOPs: TXOP1 and TXOP2, each TXOP includes only one TB perception measurement instance, where TXOP1 includes TB perception measurement instance 1 and TXOP2 includes TB perception measurement instance 2.

[0302] It is worth noting that a TB perception measurement instance may include one or more of the NDPA detection phase, TF detection phase, and reporting phase.

[0303] As shown in Figure 10, during the polling phase of TB perception measurement instance 1 in TXOP1, the AP sends a perception polling trigger frame to STA 1, STA 2, and STA 3, and uses the perception polling trigger frame to ask STA 1 and STA 2 whether to participate in the perception measurement. This means that only STA 1 and STA 2 will participate in the TB perception measurement instance in TXOP 1, and STA 3 will not participate in the TB perception measurement instance. Here, the user information list (User Info List) field of the perception polling trigger frame sent by the AP during the polling phase of TB perception measurement instance instanc1 carries two user information fields (User Info field). The AID12 / USID12 subfields of the two User Info fields indicate the AID / USID of STA 1 and STA 2, respectively. As shown in Figure 10, after STA 1 and STA 2 receive the perception polling trigger frame, they return a CTS-to-self frame to the AP, and STA 1 and STA 2 then participate in the NDPA detection phase, TF detection phase, and reporting phase in the subsequent TB perception measurement instance. When STA 3 receives the Awareness Poll Trigger frame and finds that it does not indicate STA 3's AID / USID, it immediately enters the doze state. The doze state ends at the end of TXOP 1, which is indicated in the Duration / ID field of the Awareness Poll Trigger frame. At the end of TXOP 1, STA 3 resumes the awake state.

[0304] As shown in Figure 10, during the polling phase of TB perception measurement instance 2 of TXOP2, the AP sends a perception polling trigger frame 2 to STA 1, STA 2, and STA 3, and uses the perception polling trigger frame to ask STA 3 whether to participate in the perception measurement. This means that only STA 3 will participate in the TB perception measurement instance in TXOP 2. After receiving the perception polling trigger frame, STA 3 returns a CTS-to-self frame to the AP to participate in the subsequent NDPA detection phase, TF detection phase, and reporting phase in TB perception measurement instance 2. After STA 1 and STA 2 receive the perception polling trigger frame, they find that the perception polling trigger frame does not indicate the AID / USID of STA 1 and STA 2, so STA 1 and STA 2 immediately enter the doze state. The end time of STA 1 and STA 2's doze is the end time of the current TXOP. It is worth noting that the duration of the TXOP is indicated in the Duration / ID field of the perception polling trigger frame, and the duration of the perception available window is indicated in the Sensing Measurement Setup Request / Response frame. The User Info List field of the perception polling trigger frame carries one User Info field. The AID12 / USID12 subfield of the User Info field indicates the AID / USID of STA 3.

[0305] In Example 1, the AP and multiple STAs can operate on the same 20 MHz channel, or on the same 40 MHz, 80 MHz, 160 MHz, or 320 MHz. This embodiment of the present application is not limited to this. That is, in the scenarios and schematic diagrams described in this application, the AP may transmit on 20 MHz, 40 MHz, 80 MHz, 160 MHz, or 320 MHz.

[0306] Example 2: One TXOP has multiple TB perception measurement instances

[0307] A sensing availability window contains m TXOPs, each of which contains n TB sensing measurement instances. Note that a TB sensing measurement instance can include one or more of the NDPA detection phase, TF detection phase, and reporting phase.

[0308] As shown in FIG11 , it is assumed that the sensing available window includes 2 TXOPs, and each TXOP includes 2 TB sensing measurement instances.

[0309] Option 1: The first TB perception measurement instance of each TXOP uses a perception polling trigger frame to query all STAs participating in the TXOP, and subsequent perception polling trigger frames of the TXOP query a subset of all STAs participating in the TXOP.

[0310] As shown in Figure 12, assuming that STA 1, STA 2, and STA 3 are assigned to the sensing available window, during the polling phase of the TB sensing measurement instance of TXOP 1, the AP sends a sensing polling trigger frame to STA 1, STA 2, and STA 3, and uses the sensing polling trigger frame to inquire whether STA 1 and STA 2 participate in the sensing measurement. This means that only STA 1 and STA 2 participate in the sensing measurement of TB sensing measurement instance 1 and TB sensing measurement instance 2 of TXOP 1, and STA 1 and STA 2 need to remain awake during TXOP 1. STA 3 does not participate in the TB sensing measurement instance of TXOP 1 and can enter a dormant state until the end of the current TXOP 1. After the end of the current TXOP 1, STA 3 remains awake and listens for the AP sending the sensing polling trigger frame during the polling phase of the first TB sensing measurement instance of the next TXOP, TXOP 2. TXOP 2 may include one or more TB sensing measurement instances, and the details of TXOP 2 can refer to TXOP 1.

[0311] As shown in Figure 12, after the AP sends the Sensing Polling Trigger frame during the polling phase of the first TB sensing measurement instance, it then sends a Sensing NDPA frame to STA 1. STA 1 participates in the NDPA detection phase, TF detection phase, and reporting phase of the first TB sensing measurement instance, while STA 2 does not participate in the first TB sensing measurement instance of this TXOP (TXOP 1). The AP then sends a Sensing Polling Trigger frame 2 to STA 2 again during the polling phase of the second TB sensing measurement instance, informing STA 2 to participate in the second TB sensing measurement instance. The AP then sends a Sensing Detection Trigger frame to STA 2, causing STA 2 to participate in the TF detection phase, NDPA detection phase, and reporting phase of the second TB sensing measurement instance.

[0312] During the polling phase of the second TB perception measurement instance and subsequent TB perception measurement instances, the perception polling trigger frame can only query a subset of STAs that the AP has queried during the polling phase of the first TB perception measurement instance.

[0313] Option 2: The perception polling trigger frame of the first TB perception measurement instance of each TXOP queries all STAs participating in the TXOP. There is no subsequent polling phase of the TXOP (i.e., no perception polling trigger frame). At this time, the timing design of the existing TB perception measurement instance phase needs to be modified.

[0314] As shown in Figure 13, assuming that STA 1, STA 2, and STA 3 are assigned to the available sensing window, during the polling phase of the first TB sensing measurement instance of the first TXOP, the AP sends a sensing polling trigger frame to STA 1, STA 2, and STA 3, and uses the sensing polling trigger frame to inquire whether STA 1 and STA 2 participate in the TB sensing measurement of this TXOP. This means that only STA 1 and STA 2 participate in the TB sensing measurement instance of this TXOP (TXOP 1) (i.e., the first and second TB sensing measurement instances), and STA 1 and STA 2 need to remain awake during this TXOP 1. STA 3 does not participate in the TB sensing measurement instance of this TXOP (TXOP 1) and can enter a dormant state until the end of the current TXOP (TXOP 1). After the end of the current TXOP (TXOP 1), STA 3 remains awake and listens for the sensing polling trigger frame sent by the AP during the polling phase of the first TB sensing measurement instance of the next TXOP (TXOP 2).

[0315] As shown in Figure 13, after the AP sends the Sensing Polling Trigger frame in the polling phase of the first TB sensing measurement instance, it then sends a Sensing NDPA frame to STA 1. STA 1 participates in the NDPA detection phase, TF detection phase, and reporting phase of the first TB sensing measurement instance, while STA 2 does not participate in the TB sensing measurement instance of the first TB sensing measurement instance of this TXOP (TXOP 1). Then, in the second TB sensing measurement instance (and subsequent TB sensing measurement instances), there is no longer a polling phase. The AP directly sends a Sensing Detection Trigger frame to STA 2, and STA 2 participates in the TF detection phase, NDPA detection phase, and reporting phase of the second TB sensing measurement instance.

[0316] In this embodiment of the present application, the More TF field in the Perception Polling Trigger Frame is used to indicate whether there are more Perception Polling Trigger Frames to be sent in the current Perception Available Window. For example, if More TF = 1, it means that there are more Perception Polling Trigger Frames to be sent in the current Perception Available Window; if More TF = 0, it means that there are no more Perception Polling Trigger Frames to be sent in the current Perception Available Window. The indication of the More TF field does not serve as an indication of whether the STA enters the sleep state.

[0317] Example 3: The TF detection phase includes multiple TF Sounding sub-phases

[0318] In Example 1 and Example 2, the AP sends a perception detection trigger frame only once during the TF detection phase, and the STA sends an NDP after the SIFS time, that is, it includes a TF Sounding sub-phase. As shown in Figure 14, the TF detection phase includes multiple TF Sounding sub-phases, that is, the operation of "AP sends a perception detection trigger frame, and the STA sends an NDP after the SIFS time" is repeated multiple times, and the time interval between each STA sending an NDP and the AP sending a perception detection trigger frame is SIFS.

[0319] As shown in Figure 14, as another example of embodiment 1, in the TF detection phase of the first TB perception measurement instance of TXOP 1, the AP first sends a perception detection trigger frame to STA 1 to trigger STA 1 to send an NDP frame, and then the AP sends a perception detection trigger frame to STA 2 to trigger STA 2 to send an NDP frame.

[0320] In an embodiment of the present application, the perception polling trigger frame is a variant of the basic trigger frame (BasicTrigger frame) shown in Figure 15. For example, the value of the Trigger Type subfield of the Common Info field is 8, which is defined as a ranging / sensing type trigger frame.

[0321] The format of the basic trigger frame is shown in Figure 15. It includes the following fields: Frame Control (2 bytes), Duration (2 bytes), Receive Address (RA) (6 bytes), Transmitter Address (TA) (6 bytes), Comminfo (8 or more bytes), User Info List (variable bytes), Padding (variable bytes), and Frame Check Sequence (FCS) (4 bytes). Frame Control, Duration, RA, and TA constitute the MAC header.

[0322] The format of the Common Info field is shown in FIG16 , and includes the following fields: a trigger type (Trigger Type) occupying 4 bits and a trigger dependent common information (Trigger Dependent Common Info) occupying a variable number of bits. The Common Info field may also include: UL length (12 bits), more TF (1 bit), CS requirement (1 bit), UL BW (2 bits), G1 and HE / EHT-LTF type / triggered TXOP sharing mode (2 bits), reserved (1 bit), number of HE / EHT-LTF symbols (3 bits), reserved (1 bit), LDPC additional symbol segment (1 bit), AP Tx Power (6 bits), Pre-FECPadding Factor (2 bits), PE Disambiguity (1 bit), UL Spatial Reuse (16 bits), reserved (1 bit), HE / EHT (1 bit), and Special User Info Field Flag (1 bit). Flag), ETH reserved which occupies 7 bits, and reserved which occupies 1 bit.

[0323] The frame format of the Trigger Dependent Common Info subfield is shown in Figure 17 and includes the following subfields: Sensing Trigger Subtype (4 bits), Sensing (1 bit), and Reserved (3 bits). Setting the Sensing subfield to 1 indicates that the trigger frame of the Ranging / Sensing type with Trigger Type = 8 is a Sensing Trigger frame. As shown in Table 1, setting the Sensing Trigger Subtype field to 0 indicates that the Sensing Trigger frame is a Sensing Polling Trigger frame; setting the Sensing Trigger Subtype field to 1 indicates that the Sensing Trigger frame is a Sensing Detection Trigger frame; setting the Sensing Trigger Subtype field to 2 indicates that the Sensing Trigger frame is a Sensing Reporting Trigger frame; and Sensing Trigger Subtype fields = 3 to 15 are reserved.

[0324] Table 1. Examples of values ​​and meanings of perception trigger subtypes

[0325] Perception Trigger Subtype Value Perception Trigger Frame Variant 0 Poll 1 Sounding 2 Report 3-15 Reserved

[0326] Among them, the RA field of the perception polling trigger frame can be set to a broadcast address or a multicast address. The perception polling trigger frame sent by the AP can be received and demodulated by all STAs around it. The STA demodulates and obtains the AID12 / USID12 in the User Info field to know whether the frame is used to trigger / inquire itself.

[0327] As shown in Figure 18, the frame format of the User Info List field includes one or more user information (User Info) fields. The User Info field includes AID12 / USID12 occupying 12 bits. AID12 / USID12 indicates the AID or USID of the queried site. Among them, one User Info field corresponds to one queried site. Therefore, the number of User Info fields included in the User Info List field is the same as the number of queried sites.

[0328] The User Info field may also include the following fields: RU Allocation (8 bits), uplink forward error correction (FEC) coding type (UL FEC Coding Type) (1 bit), uplink high-efficiency modulation and coding scheme (MCS) (UL HE-MCS) (4 bits), UL DCM (1 bit), spatial stream (SS) allocation / random access resource unit (RA-RU) information (SS Allocation / RA-RU Information) (6 bits), uplink target receive power (UL Target Receive Power) (7 bits), and reserved (1 bit).

[0329] The wireless communication method provided in the embodiments of the present application has at least the following technical effects:

[0330] Technical Effect 1: During the polling phase of the first TB awareness measurement instance of each TXOP, the AP polls all STAs participating in the TB awareness measurement instance. Subsequent TB awareness measurement instances no longer require the AP to send a poll and can directly enter the TB awareness measurement instance, thus saving the polling phase of the second TB awareness measurement instance and subsequent instances of each TXOP.

[0331] Technical Effect 2: During the polling phase of the first TB awareness measurement instance of each TXOP, the AP polls all STAs participating in the TB awareness measurement instance. STAs that are not polled can enter a dormant state until the end of the current TXOP, providing STAs with more dormant opportunities and enabling devices to save more power.

[0332] Non-TB perception measurement examples

[0333] If the STA is only the sensing transmitter (i.e., the AP is not the sensing transmitter), then the R2I NDP sent by the AP uses two (or other) LTF symbols to indicate the termination of the current non-TB sensing measurement setup. When the STA receives the R2I NDP sent by the AP and finds that the R2I NDP is configured with two (or other) LTF symbols, the STA, as the sensing initiator, automatically terminates the non-TB measurement setup.

[0334] If the STA is only a sensing receiver (that is, the AP is a sensing transmitter), the number of LTF symbols configured in the R2I NDP sent by the AP is the number of LTF symbols indicated in the NDPA sent by the STA + 1 (or -1, or other) LTF symbol, thereby implying the termination of the current non-TB measurement setup; when the STA receives the R2I NDP sent by the AP and finds that the R2I NDP is configured with the number of LTF symbols indicated in the NDPA + 1 (or other) LTF symbol, the STA, as the sensing initiator, defaults to the termination of the non-TB measurement setup.
