[0071] It should be understood that although the terms first, second, etc. may be used in this application to describe various information, these information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, a first parameter may also be referred to as a second parameter, and similarly, a second parameter may also be referred to as a first parameter. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0072] Some key terms in this application are briefly introduced as follows:

[0073] WLAN Sensing: This technology detects people and objects in the environment by measuring changes in WLAN signal scattering and / or reflection caused by people and objects. In other words, WLAN sensing uses wireless signals to measure and perceive the surrounding environment, enabling functions such as indoor intrusion, movement, and fall detection, gesture recognition, and spatial 3D image creation.

[0074] Association Identifier (AID): used to identify a terminal after establishing an association with an access point.

[0075] WLAN devices participating in WLAN awareness may include the following roles:

[0076] Sensing Initiator: Also known as the sensing session initiator, sensing initiating device, or sensing initiating apparatus. A sensing initiator is the device that initiates sensing measurements and wants to obtain the sensing results.

[0077] Sensing Responder: Also known as a sensing session responder, sensing response device, or sensing response apparatus. A sensing responder is a device that participates in sensing measurements other than the sensing initiator.

[0078] Sensing Transmitter: Also known as a sensing signal sending device, sensing sender, sensing sending device, or sensing sending apparatus. A sensing signal sender is a device that sends sensing physical layer protocol data units (PPDUs).

[0079] Sensing Receiver: Also known as a sensing signal receiving device, sensing receiver, sensing receiving equipment, or sensing receiving apparatus. A sensing signal receiver is a device that receives echo signals. Echo signals are the result of scattering and / or reflection of the sensing physical layer protocol data unit (PDU) sent by the sensing signal sender.

[0080] A WLAN terminal may have one or more roles in a perception measurement. For example, a perception initiator can be solely a perception initiator, a perception signal sender, a perception signal receiver, or both. These devices are collectively referred to as perception measurement devices.

[0081] Next, the relevant technical background involved in the embodiments of this application is introduced:

[0082] Figure 1 is a schematic diagram of a perception measurement system 10 provided by an exemplary embodiment of the present application. The perception measurement system includes terminals, terminals and network devices, or access points (APs) and stations (STAs), though this application does not limit this. This application uses the perception measurement system including AP 110 and STA 120 as an example for illustration.

[0083] In some scenarios, an AP can be referred to as an AP STA, meaning that in a sense, an AP is also a type of STA. In some scenarios, a STA can be referred to as a non-AP STA.

[0084] In some embodiments, STAs may include AP STAs and non-AP STAs.

[0085] Communication in a communication system can be between an AP and a non-AP STA, between a non-AP STA and a non-AP STA, or between a STA and a peer STA. A peer STA refers to a device that communicates with the STA peer. For example, a peer STA may be an AP or a non-AP STA.

[0086] An AP acts as a bridge between wired and wireless networks, connecting wireless network clients together and then connecting the wireless network to the Ethernet. An AP can be a terminal device (such as a mobile phone) or a network device (such as a router) equipped with a Wireless Fidelity (Wi-Fi) chip.

[0087] It should be understood that the role of STA in the communication system is not absolute. For example, in some scenarios, when a mobile phone is connected to a router, the mobile phone is a non-AP STA. When the mobile phone serves as a hotspot for other mobile phones, the mobile phone plays the role of AP.

[0088] APs and non-AP STAs 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.

[0089] In some embodiments, non-AP STAs may support, but are not limited to, 802.11bf. Non-AP STAs 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.

[0090] In some embodiments, the AP may be a device supporting 802.11bf. 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.

[0091] In an embodiment of the present application, the STA may be a mobile phone, tablet computer, computer, virtual reality (VR) device, augmented reality (AR) device, wireless device in industrial control, set-top box, wireless device in unmanned driving, vehicle-mounted communication equipment, wireless device in telemedicine, wireless device in smart grid, wireless device in transportation safety, wireless device in smart city or wireless device in smart home, wireless communication chip / ASIC / SOC / etc. that supports WLAN / Wi-Fi technology.

[0092] WLAN technology can support frequency bands including but not limited to: low frequency bands (2.4GHz, 5GHz, 6GHz) and high frequency bands (60GHz).

[0093] One or more links exist between a station and an access point.

[0094] In some embodiments, stations and access points support multi-band communications, for example, communicating simultaneously on the 2.4 GHz, 5 GHz, 6 GHz, and 60 GHz frequency bands, or communicating simultaneously on different channels within the same frequency band (or different frequency bands), thereby improving the communication throughput and / or reliability between devices. Such devices are generally referred to as multi-band devices, or multi-link devices (MLDs), and are sometimes also referred to as multi-link entities or multi-band entities. A multi-link device can be an access point device or a station device. If the multi-link device is an access point device, the multi-link device includes one or more APs; if the multi-link device is a station device, the multi-link device includes one or more non-AP STAs.

[0095] A multi-link device including one or more APs is called an AP, and a multi-link device including one or more non-AP STAs is called a Non-AP. In the embodiment of the application, the Non-AP can be called a STA.

[0096] In an embodiment of the present application, the AP may include multiple APs, the Non-AP may include multiple STAs, multiple links may be formed between the APs in the AP and the STAs in the Non-AP, and data communication may be performed between the APs in the AP and the corresponding STAs in the Non-AP through the corresponding links.

[0097] An AP is a device deployed in a wireless local area network to provide wireless communication capabilities for STAs. A station may include: User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless communication device, a user agent, or a user device. Optionally, a station may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, or a wearable device, but the embodiments of the present application are not limited to this.

[0098] In the embodiment of the present application, both the station and the access point support the IEEE 802.11 standard, but are not limited to the IEEE 802.11 standard. They may also be other standards related to perception measurement, such as the IEEE 802.11bf D0.1 standard.

[0099] In the WLAN sensing scenario, the WLAN terminals participating in sensing include: sensing initiators and sensing responders. Furthermore, sensing responders can be divided into sensing senders and sensing receivers.

[0100] The perception measurement can be applied to a cellular network communication system, a WLAN system or a Wi-Fi system, and this application does not limit this. In this application, the perception measurement is applied to a WLAN or Wi-Fi system as an example for schematic description.

[0101] Optionally, the perception measurement in the embodiment of the present application is implemented based on millimeter waves. The millimeter wave perception type is introduced as follows:

[0102] FIG2 is a schematic diagram of a millimeter wave sensing type provided by an exemplary embodiment of the present application. As shown in FIG2 , FIG2 (a) is single-base sensing, in which there is only one device participating in the sensing. The device senses the environment by spontaneously sending (self-sending) sensing PPDUs and self-receiving (self-receiving) echo signals, similar to the working mode of traditional radars. Wherein, spontaneous sending and self-receiving means that when a device sends a sensing PPDU, the sender address and the receiver address of the sensing PPDU are both set to the device's own address. The sensing PPDU sent by the device will form an echo signal after being scattered and / or reflected by the environment. The device can then receive the echo signal through its own address and perceive the environment by analyzing the echo signal. FIG2 (b) is dual-base sensing, in which there are two devices participating in the sensing, one of which sends the sensing PPDU and the other receives the echo signal to sense the environment. FIG2 (c) is collaborative single-base sensing, in which the number of devices participating in the sensing is greater than one. Each device senses the environment by spontaneously sending a sensing PPDU and self-receiving an echo signal. There is a sensing initiator that controls all other devices to achieve collaboration. Figure 2(d) illustrates collaborative dual-base sensing, where more than two devices participate in sensing. This means there are at least two pairs of dual-base sensing devices. Each transmitting device (sensing sender) transmits a sensing PPDU, and the corresponding echo signal is received by the receiving devices in the same group (sensing receivers), thus achieving collaborative sensing. Figure 2(e) illustrates multi-base sensing, where more than two devices participate in sensing. A single transmitting device transmits a sensing PPDU, and multiple receiving devices simultaneously receive the echo signal and complete environmental sensing.

[0103] This section describes the millimeter wave sensing process:

[0104] Figure 3 is a schematic diagram of the millimeter wave perception process provided by an exemplary embodiment of the present application. As shown in Figure 3, the process is a general process of millimeter wave perception, which includes, from left to right, the session establishment phase, the millimeter wave perception measurement setup (directional multi-gigabit (DMG) Measurement setup) phase, and the perception measurement phase. Among them, the perception measurement phase consists of multiple perception measurement bursts, and each burst consists of multiple perception measurement instances. The time interval between bursts is the inter-burst interval, and the time interval between adjacent perception measurement instances in a burst is the intra-burst interval. In Figure 3, MAC ADDR refers to the Medium Access Control (MAC) address, AID refers to the association identifier, DMG measurement setup ID (DMG Measurement setup Identity Document) refers to the millimeter wave perception measurement setup identifier, MS ID refers to the measurement setup (MS) identifier, burst ID refers to the burst identifier, and instance serial number (SN) refers to the identifier of the perception measurement instance, which can also be called the perception instance SN or perception instance ID.

[0105] In the millimeter wave sensing measurement process of related technologies, the sensing participating devices need to be able to obtain the angular information of the sensing beam, and therefore require information about the beam azimuth and / or beam elevation. However, the frame format design of related technologies cannot accurately indicate the beam azimuth and beam elevation, resulting in inaccurate coordinate system indication of the sensing beam angle, affecting the normal operation of the sensing process. The sensing measurement method provided in this application can effectively solve this problem.

[0106] FIG4 is a flowchart of a perception measurement method provided by an exemplary embodiment of the present application. This embodiment illustrates the method as being performed by a perception participating device, which includes at least one of a perception initiating device and a perception responding device. The method includes:

[0107] Step 410: Send or receive a frame carrying a first field during the perception measurement process, where the first field is used to indicate information related to coordinate system settings.

[0108] The information related to the coordinate system setting is setting information or configuration information related to the coordinate system used in the perception measurement process. Optionally, the information related to the coordinate system setting includes: the type of the reference coordinate system.

[0109] In some embodiments, the first field is a coordinates field, which is used to indicate the type of the reference coordinate system. The type of the reference coordinate system includes at least one of the following:

[0110] Earth coordinate system;

[0111] The coordinate system of any STA.

[0112] Among them, the coordinate system of any STA can be the coordinate system of the perception initiating device, or the coordinate system of the perception responding device, or the coordinate system of the perception sending device, or the coordinate system of the perception receiving device.

[0113] To sum up, the perception measurement method provided in this embodiment, by sending or receiving a frame carrying the first field during the perception measurement process, can set or negotiate information related to the coordinate system between the perception participating devices, thereby clearly indicating the coordinate system of the azimuth / elevation angle, ensuring the normal progress of the response perception process, and ensuring the accuracy of the perception measurement results.

[0114] 1.1 During the perception session establishment phase or the perception measurement setup phase, frames carrying coordinate fields are sent or received:

[0115] In some embodiments, sending or receiving a frame carrying the first field during a perception measurement process includes at least one of the following two steps:

[0116] During the perception session establishment phase, frames carrying coordinate fields are sent or received;

[0117] During the perception measurement setup phase, frames carrying coordinate fields are sent or received.

[0118] The sensing measurement process can be divided into at least the following types: the sensing measurement process based on trigger frames (TB) (Figure 5), the sensing measurement process based on non-trigger frames (Non-Trigger Based, Non-TB) (Figure 6), and the sensing measurement process based on passive sensing (7). Among them, the sensing measurement process based on non-trigger frames can also be called non-trigger based frames (Non-Trigger Based, Non-TB).

[0119] Figure 5 is a schematic diagram of a perception measurement process established by a perception initiating device and a perception responding device provided by an exemplary embodiment of the present application. Exemplarily, the perception initiating device is an AP and the perception responding device is an associated STA.

[0120] First, during the awareness session establishment phase, the STA obtains the wireless network information of the AP through passive scanning or active scanning to understand the distribution of surrounding wireless networks.

[0121] Passive scanning: refers to the STA passively listening to the beacon frames periodically broadcast by the AP on a specified channel. Among them, the beacon frame can carry information such as capability information and service set identifier (SSID);

[0122] Active scanning: A STA actively sends a Probe Request frame to an AP and receives a Probe Response frame in return. These frames can carry information such as capabilities, SSID, and extended capabilities. The capabilities information in these frames refers to the capabilities of the device sending the frame.

[0123] Secondly, the STA establishes an association with a certain AP based on the acquired wireless network information of the AP, so as to obtain full access to the wireless network and thus become an associated STA.

[0124] When a STA connects to an AP for the first time, it unicasts an Association Request frame to the AP and receives an Association Response frame from the AP. The Association Request frame can carry information such as capability information, Listen Interval, SSID, supported rates, and Quality of Service (QoS) capability. The Association Response frame can carry information such as capability information, Status Code, Association Identify (AID), and extended capabilities.

[0125] When a STA is not connecting to an AP for the first time, it unicasts a Reassociation Request frame to the AP and receives a Reassociation Response frame from the AP. The Reassociation Response frame carries information similar to that of the Association Request and Association Response frames.

[0126] Next, during the sensing measurement setup phase, based on the various capability information exchanged between the STA and AP in the above steps, the AP sends a sensing measurement setup request frame (MS Request frame) to the associated STA and receives a returned sensing measurement setup response frame (MS Response frame), thereby completing the setup of a sensing measurement. The sensing measurement setup request frame can carry information such as the measurement frame (Null Data Physical layer Protocol Data Unit, NDP) bandwidth, NDP type, and reporting type; the sensing measurement setup response frame can carry information such as the status code.

[0127] Finally, in the perception measurement instance phase, a perception measurement instance is established between the associated STA and the AP, and NDPs are sent and received to perform channel perception.

[0128] Figure 6 is a schematic diagram of a perception measurement process established by a perception initiating device and a perception responding device provided by an exemplary embodiment of the present application. In the perception session establishment phase, the process of establishing perception between a non-associated STA and an AP is similar to the process of an associated STA, and both use beacon frames, probe request frames, and probe response frames to scan the wireless network information of the AP.

[0129] The difference is that non-associated STAs do not need to establish an association relationship with the AP. That is, they do not need to send association request frames and receive association response frames to the AP, nor do they need to send reassociation request frames and receive reassociation response frames to the AP. During the perception measurement setup phase, non-associated STAs can send a perception measurement setup query frame (MS Query frame) to the AP after scanning to initiate the perception measurement setup step. They then complete the perception measurement setup step by receiving the perception measurement setup request frame and sending the perception measurement setup response frame.

[0130] Finally, in the perception measurement instance phase, a perception measurement instance is established between the unassociated STA and the AP, and NDPs are sent and received to perform channel perception.

[0131] Figure 7 is a schematic diagram of a perception measurement process established by a perception initiating device and a perception responding device provided by an exemplary embodiment of the present application. Exemplarily, the perception initiating device is an AP and the perception responding device is a non-associated STA.

[0132] STAs passively listen to the AP's periodic broadcast of beacon and announcement frames on a designated channel to obtain the AP's wireless network information. The STA then sends an information request frame to the AP, which then sends an information response frame to the STA.

[0133] In some embodiments, the frame structure of a beacon frame is shown in FIG8 , and includes, in order: a Frame Control field, a Duration field, a Basic Service Set Identifier (BSSID) field, a Frame Body field, and a Frame Checksum (FCS) field. The Frame Control field occupies 2 bytes, the Duration field occupies 2 bytes, the BSSID field occupies 6 bytes, the Frame Body field occupies a variable number of bytes, and the Frame Checksum field occupies 4 bytes. The Frame Body field of a DMG beacon frame may carry at least one of a DMG Aware Beam Descriptor element and a DMG Aware Short Capability element.

[0134] In some embodiments, an association request frame, an association response frame, a reassociation request frame, a reassociation response frame, a probe request frame, and a probe response frame are all subtypes of a management frame. The Type and Subtype fields in the Frame Control field jointly indicate which subtype of the management frame it is.

[0172] In order to solve the problem of inaccurate coordinate system indication of the perception beam angle, the present application adds a coordinate field in the DMG perception beam descriptor element.

[0173] 1.2.1.1 Example 1:

[0174] The coordinate field is a field at the same level as the N beam descriptor fields and is used to indicate the reference coordinate system of all beam azimuth and beam elevation fields in the DMG perception beam descriptor element. When the coordinate field value is the first value, it indicates the Earth coordinate system; when the coordinate field value is the second value, it indicates any STA coordinate system.

[0175] Exemplarily, a coordinate field is added to the DMG perception beam descriptor element, as shown in Figure 14. Figure 14 is a schematic diagram of the element structure of the DMG perception beam descriptor element provided by an exemplary embodiment of the present application, including the following arranged in sequence: element ID field, length field, element ID extension field, transmission identification field, coordinate field, beam descriptor 1 field to beam descriptor N field. Among them, the element ID field occupies 1 byte, the length field occupies 1 byte, the element ID extension field occupies 1 byte, the transmission identification field occupies 1 byte, the coordinate field occupies 1 byte, and the beam descriptor 1 field to the beam descriptor N field each occupy 6 bytes.

[0176] In some embodiments, the beam descriptor 1 field is the same as the beam descriptor 1 field in Figure 13 and is not repeated here.

[0177] The coordinate field indicates the reference coordinate system for all beam azimuth subfields and beam elevation subfields in the DMG Perception Beam Descriptor element. The coordinate field can take any two values ​​between 0 and 255. For example, a value of 1 in the coordinate field indicates the Earth coordinate system (for example, beam azimuth = 0 is north, and beam elevation = 0 is the horizon); a value of 0 in the coordinate field indicates any STA coordinate system. If the Earth Coordinate field in the DMG Perception Short Capability element takes a value of 0, the value of this field is unique (only 1 or only 0) and indicates any STA coordinate system.

[0178] In different embodiments, the coordinate field may also take a value of 0 to indicate the earth coordinate system; or a value of 1 to indicate any STA coordinate system, which is not limited in this application.

[0179] This embodiment adds a coordinate field to the DMG perception beam descriptor element so that the coordinate field indicates the reference coordinate system of all beam azimuth subfields and beam elevation subfields in the DMG perception beam descriptor element, thereby reducing overhead, unifying the coordinate system indicating the azimuth / elevation angle, ensuring the normal progress of the response perception process, and ensuring the accuracy of the perception measurement results.

[0180] 1.2.1.2 Example 2:

[0181] The coordinate field corresponds one-to-one with the beam descriptor field and is used to indicate the reference coordinate system of the beam azimuth field and beam elevation field in the beam descriptor field. That is, the DMG perception beam descriptor element includes N beam descriptor fields, and the subfields of each beam descriptor field include: beam azimuth field, beam elevation field, and coordinate field, where N is a positive integer. When the coordinate value is the first value, it indicates the earth coordinate system; when the coordinate value is the second value, it indicates any STA coordinate system.

The element ID field occupies 1 byte, the length field occupies 1 byte, the element ID extension field occupies 1 byte, the transmission identification field occupies 1 byte, and the beam descriptor 1 to beam descriptor N fields each occupy 7 bytes.

[0183] In some embodiments, the beam descriptor 1 field includes, in order: a beam azimuth subfield, a beam elevation subfield, an azimuth beamwidth subfield, an elevation beamwidth subfield, a beam gain subfield, a coordinate subfield, and a reserved subfield. The beam azimuth subfield occupies 12 bits (B0-B11), the beam elevation subfield occupies 12 bits (B12-B23), the azimuth beamwidth subfield occupies 9 bits (B24-B32), the elevation beamwidth subfield occupies 8 bits (B33-B40), the beam gain subfield occupies 7 bits (B41-B47), the coordinate subfield occupies 1 bit (B48), and the reserved subfield occupies 7 bits (B49-B55).

[0184] The coordinate subfield indicates the reference coordinate system of the beam azimuth and beam elevation subfields in the beam descriptor field where the subfield is located. That is, the coordinate subfield in the i-th beam descriptor field is used to indicate the reference coordinate system of the beam azimuth and beam elevation subfields in the i-th beam descriptor field. Exemplarily, the coordinate subfield takes a value of 1 to indicate the earth coordinate system (for example, beam azimuth = 0 is north, beam elevation = 0 is the horizon); the coordinate subfield takes a value of 0 to indicate any STA coordinate system. If the earth coordinate field in the DMG perception short capability element takes a value of 0, the value of this field is unique (only 1 or only 0) and indicates any STA coordinate system.

[0185] In different embodiments, the coordinate field may also take the value 0 to indicate the earth coordinate system (for example, beam azimuth = 0 is north, beam elevation = 0 is horizon); the value 1 to indicate any STA coordinate system, which is not limited in this application.

[0186] This embodiment adds a coordinate subfield to the DMG perception beam descriptor element, so that the coordinate subfield indicates the reference coordinate system of the beam azimuth subfield and the beam elevation subfield in the beam descriptor field, thereby flexibly indicating the coordinate system of the azimuth / elevation angle, ensuring the normal progress of the response perception process, and ensuring the accuracy of the perception measurement results.

[0205] The Coordinates field indicates the reference coordinate system for all sector azimuth and sector elevation subfields in the DMG Beacon Sector Descriptor element in which this field is located. The Coordinates field can take any two values ​​between 0 and 255. For example, a value of 1 in the Coordinates field indicates the Earth coordinate system (e.g., sector azimuth = 0 is north, sector elevation = 0 is horizon); a value of 0 indicates any STA coordinate system.

For example, a value of 1 in the Coordinates subfield indicates the Earth coordinate system (e.g., Sector Azimuth = 0 is North, Sector Elevation = 0 is Horizon); a value of 0 in the Coordinates subfield indicates any STA coordinate system. If the Earth Coordinates field in the DMG Perception Short Capabilities element is 0, this field has a unique value (either 1 or 0) and indicates any STA coordinate system.

[0236] In different embodiments, the coordinate subfield may also take a value of 0 to indicate the earth coordinate system; or a value of 1 to indicate any STA coordinate system, which is not limited in this application.

[0237] This embodiment adds a coordinate subfield to the DMG passive perception beacon information element, so that the coordinate subfield indicates the reference coordinate system of the sector azimuth subfield and the sector elevation subfield in the DMG beacon sector descriptor element carried in the frame where the element is located, thereby flexibly indicating the coordinate system of the azimuth / elevation angle, ensuring the normal progress of the response perception process, and ensuring the accuracy of the perception measurement results.

[0238] 1.2.4 Introduction to DMG perception short ability elements:

[0239] Figure 22 is a schematic diagram of the element structure of the DMG Sensing Short Capabilities element provided by the related art, which includes the following fields: Element ID field, Length field, Element ID extension field, and DMG Sensing Short Capabilities field. The Element ID field occupies 1 byte, the Length field occupies 1 byte, the Element ID extension field occupies 1 byte, and the DMG Sensing Short Capabilities field occupies 1 byte.

[0240] In some embodiments, the DMG Sensing Short Capability field includes, in order: a Sensing Support subfield, a Passive Sensing Support subfield, an Accurate Timing of Beacons subfield, a Location Available subfield, an Earth Coordinates subfield, and a Reserved subfield. The Sensing Support subfield B0 occupies 1 bit, the Passive Sensing Support subfield occupies 1 bit B1, the Accurate Timing of Beacons subfield occupies 1 bit B2, the Available Location subfield occupies 1 bit B3, the Earth Coordinates subfield occupies 1 bit B4, and the Reserved subfield occupies 3 bits B5 to B7.

[0241] The meanings of the fields in the DMG-Aware Short Capability element are as follows:

[0242] Perception Support: Indicates whether any of the DMG perception types are supported.

[0243] Passive Sensing Support: Indicates whether DMG passive sensing is supported by providing beacon direction and optional location information.

[0244] Inter-beacon accurate timing: Indicates that the time interval between beacons is sample accurate.

[0245] Available Location: Indicates that the AP can provide its location information for passive sensing.

[0246] Earth Coordinates: Indicates that the STA can send azimuth and elevation in the Earth coordinate system (azimuth = 0 is north, elevation = 0 is the horizon). If this subfield is set to 0, the azimuth and elevation are relative to an arbitrary STA coordinate system.

[0247] The DMG-aware short capability element is carried in the frame body field of at least one of the following frames:

[0248] DMG beacon frame;

[0249] Association request frame;

[0250] Association response frame;

[0251] Reassociation request frame;

[0252] Reassociation response frame;

[0253] Probe request frame;

[0254] Probe response frame;

[0255] Information response frame;

[0256] Announcement frame.

[0257] In order to solve the problem of inaccurate coordinate system indication of the perception beam angle, this application modifies the meaning of the earth coordinate subfield in the DMG perception short capability element. In this application, the subfield can be simply referred to as the field.

[0258] The coordinate field in this method is the Earth Coordinate subfield in the DMG Perception Short Capability Element. When the Earth Coordinate subfield takes the first value, it indicates that the STA can only send the azimuth and elevation of the Earth coordinate system. That is, the meaning of modifying the Earth Coordinate subfield is to indicate that the STA can only send the azimuth and elevation in the Earth coordinate system (azimuth = 0 is north, elevation = 0 is the horizon). If this subfield is set to 0, the azimuth and elevation are relative to an arbitrary STA coordinate system.

[0259] This embodiment modifies the meaning of the earth coordinate subfield in the DMG perception short capability element so that the coordinate field indicates the reference coordinate system of the azimuth subfield and the elevation subfield in the frame where the element is located, thereby clearly indicating the coordinate system of the azimuth / elevation angle, ensuring the normal progress of the response perception process, and ensuring the accuracy of the perception measurement results.

[0260] 1.3 For the perception measurement setup phase:

[0261] During the perception measurement setting phase, the coordinate field is carried in the DMG perception measurement setting element to indicate the reference coordinate system of the azimuth field and elevation field in the DMG perception measurement setting element.

[0262] In some embodiments, the sensing initiator sends or receives a frame carrying a coordinate field to the sensing responder;

[0263] Alternatively, in some embodiments, the sensing responder sends or receives a frame carrying a coordinate field to the sensing initiator.

[0283] In addition, the LCI field carries the LCI field in the location configuration information report.

[0284] The peer location field is used to indicate the direction and distance of the peer device and includes three subfields: direction angle, elevation angle, and distance.

[0285] The optional sub-element field includes zero or more sub-elements. All sub-elements and their order are shown in Table 3 below.

[0286] Table 3

[0287]

[0288] 1.3.1.1 Example 1:

[0289] The coordinate field is a subfield of the measurement setting control field, and the azimuth field and elevation field are subfields of the opposite direction field.

[0290] When the value of the Earth Coordinate field in the DMG Perception Short Capability Element is the first value, the value of the coordinate field is unique and the reference coordinates used to indicate the azimuth field and elevation field are the coordinate system of any STA;

[0291] When the value of the Earth Coordinate field in the DMG Perception Short Capability Element is the second value and the value of the Coordinate field is the first value, the Coordinate field is used to indicate that the reference coordinates of the Azimuth field and the Elevation field are the coordinate system of any STA;

[0292] When the value of the earth coordinate field in the DMG perception short capability element is the second value and the value of the coordinate field is the second value, the reference coordinates used by the coordinate field for the azimuth field and the elevation field are the earth coordinate system.

[0293] As shown in Figure 24, Figure 24 is a schematic diagram of the element structure of the DMG perception measurement setting element provided by an exemplary embodiment of the present application. The DMG perception measurement setting element includes, in order: an element ID field, a length field, an element ID extension field, a measurement setting control field, a reporting type field, an LCI field, a peer location field, and an optional sub-element field. The element ID field occupies 1 byte, the length field occupies 1 byte, the element ID extension field occupies 1 byte, the measurement setting control field occupies 1 byte, the reporting type field occupies 1 byte, the LCI field occupies 0 or 16 bytes, the peer location field occupies 0 to 5 bytes, and the optional sub-element field occupies a variable number of bytes.

[0294] In some embodiments, the measurement setup control field includes, in order: a sensing type subfield, an RX initiator subfield, an LCI present subfield, a location present subfield, a coordinate subfield, and a reserved subfield. The sensing type subfield occupies three bits (B0-B2), the RX initiator subfield occupies one bit (B3), the LCI present subfield occupies one bit (B4), the location present subfield occupies one bit (B5), the coordinate subfield occupies one bit (B6), and the reserved subfield occupies one bit (B7). In this application, subfields may be referred to as fields.

[0295] In some embodiments, the peer location field includes, in order: an azimuth subfield, an elevation subfield, and a distance subfield. The azimuth subfield occupies 12 bits (B0-B11), the elevation subfield occupies 12 bits (B12-B23), and the distance subfield occupies 16 bits (B24-B39).

[0296] For example, a new coordinate subfield is added to the measurement setting control field. If the subfield in the measurement setting control field where the subfield is located has a subfield value of 0, the subfield is retained.

[0297] When the Earth Coordinate field in the DMG Perception Short Capability element is set to 0, the value of this subfield is unique (only 1 or only 0) and indicates that the Azimuth subfield and Elevation subfield in the Opposite End Location field are relative to any STA coordinate system.

[0298] When the value of the earth coordinate field in the DMG perception short capability element is 1, this subfield indicates the reference coordinate system of the azimuth subfield and elevation subfield in the opposite position field in the DMG perception measurement setting element. For example, when the value of the coordinate subfield is 1, it indicates the earth coordinate system, and when the value of the coordinate subfield is 0, it indicates any STA coordinate system.

[0299] This embodiment adds a coordinate subfield to the measurement setting control field of the DMG perception measurement setting element, so that the coordinate subfield indicates the reference coordinate system of the azimuth subfield and the elevation subfield in the opposite end position field in the DMG perception measurement setting element, thereby ensuring the normal progress of the response perception process and the accuracy of the perception measurement results.

[0300] 1.3.1.2 Example 2:

[0301] The coordinate field, azimuth field, and elevation field are all subfields of the opposite direction field.

[0302] When the value of the Earth Coordinate field in the DMG Perception Short Capability Element is the first value, the value of the coordinate field is unique and the reference coordinates used to indicate the azimuth field and elevation field are the coordinate system of any STA;

[0303] When the value of the Earth Coordinate field in the DMG Perception Short Capability Element is the second value and the value of the Coordinate field is the first value, the Coordinate field is used to indicate that the reference coordinates of the Azimuth field and the Elevation field are the coordinate system of any STA;

[0304] When the value of the earth coordinate field in the DMG perception short capability element is the second value and the value of the coordinate field is the second value, the reference coordinates used by the coordinate field for the azimuth field and the elevation field are the earth coordinate system.

[0305] As shown in Figure 25, Figure 25 is a schematic diagram of the element structure of the DMG perception measurement setting element provided by an exemplary embodiment of the present application. The DMG perception measurement setting element includes, in order: an element ID field, a length field, an element ID extension field, a measurement setting control field, a reporting type field, an LCI field, a peer location field, and an optional sub-element field. The element ID field occupies 1 byte, the length field occupies 1 byte, the element ID extension field occupies 1 byte, the measurement setting control field occupies 1 byte, the reporting type field occupies 1 byte, the LCI field occupies 0 or 16 bytes, the peer location field occupies 0 to 6 bytes, and the optional sub-element field occupies a variable number of bytes.

[0306] In some embodiments, the measurement setup control field includes, in order: a sensing type subfield, an RX initiator subfield, an LCI present subfield, a location present subfield, and a reserved subfield. The sensing type subfield occupies three bits (B0-B2), the RX initiator subfield occupies one bit (B3), the LCI present subfield occupies one bit (B4), the location present subfield occupies one bit (B5), and the reserved subfield occupies two bits (B6-B7). In this application, subfields may be referred to as fields.

[0307] In some embodiments, the peer location field includes, in order: an azimuth subfield, an elevation subfield, a distance subfield, a coordinate subfield, and a reserved subfield. The azimuth subfield occupies 12 bits (B0-B11), the elevation subfield occupies 12 bits (B12-B23), the distance subfield occupies 16 bits (B24-B39), the coordinate subfield occupies 1 bit (B40), and the reserved subfield occupies 7 bits (B41-B47).

[0308] Exemplarily, a coordinate subfield is added to the peer location field.

[0309] When the Earth Coordinate field in the DMG Perception Short Capability element is set to 0, the value of this subfield is unique (only 1 or only 0) and indicates that the azimuth subfield and elevation subfield in the peer location field where this subfield is located are relative to any STA coordinate system;

[0310] When the value of the earth coordinate field in the DMG perception short capability element is 1, this subfield indicates the reference coordinate system of the azimuth subfield and elevation subfield in the opposite end location field. For example, when the value of the coordinate subfield is 1, it indicates the earth coordinate system, and when the value of the coordinate subfield is 0, it indicates any STA coordinate system.

[0311] This embodiment adds a coordinate subfield to the opposite end position field of the DMG perception measurement setting element, so that the coordinate subfield indicates the reference coordinate system of the azimuth subfield and elevation subfield in the opposite end position field, thereby ensuring the normal progress of the response perception process and the accuracy of the perception measurement results.

[0312] 1.3.1.3 Example 3:

[0313] No new subfields are added. Only the meanings of the azimuth and elevation fields are modified. Both the azimuth and elevation fields are subfields of the opposite direction field.

[0314] Azimuth field: Contains the azimuth of the addressed STA measured by the STA sending the frame, in units of (360 / 4096) degrees, ranging from 0 to 4095. The azimuth coordinate system is a coordinate system relative to the direction of the STA sending the frame.

[0315] Elevation Angle field: Contains the elevation angle of the addressed STA measured by the STA sending the frame, in units of (180 / 4096) degrees, ranging from -2048 to 2047. The elevation angle coordinate system is a coordinate system relative to the orientation of the STA sending the frame.

[0316] This embodiment modifies the meaning of the azimuth angle field and the elevation angle field to ensure the normal progress of the response perception process and the accuracy of the perception measurement results.

[0317] Due to the unresolved issues in the existing frame format design in the related art, for example, in the collaborative single-base perception in parallel mode, there is no clear regulation on the format and length of the single-base PPDU, so the single-base PPDU may overlap with the perception measurement report frame, thereby causing interference, thereby affecting the normal progress of the perception process. The perception measurement method provided in this application can effectively solve this problem.

[0318] This article introduces an example of millimeter wave collaborative monostatic sensing measurement:

[0319] Millimeter-wave collaborative monostatic sensing measurement instances exist in two modes: sequential mode and parallel mode. For example, Figure 26 is a schematic diagram of an example of sequential mode for millimeter-wave collaborative monostatic sensing measurement provided by an exemplary embodiment of the present application, and Figure 27 is a schematic diagram of an example of parallel mode for millimeter-wave collaborative monostatic sensing measurement provided by an exemplary embodiment of the present application.

[0320] As shown in Figures 26 and 27, the similarities between the sequential mode and the parallel mode are that the sensing initiator needs to send a millimeter wave sensing request frame to each sensing responder at the initial stage of the sensing measurement instance, and each sensing responder needs to reply with a millimeter wave sensing response frame to the sensing initiator within the short interframe space (SIFS) time. The DMG sensing request is also called RQ, and the DMG sensing response is also called RSP.

[0321] As shown in Figures 26 and 27, the difference between sequential mode and parallel mode is that in sequential mode, each sensing responder sends and receives single-base sensing measurement frames to sense the environment, and sends a sensing measurement report frame to the sensing initiator within the SIFS time. In parallel mode, each sensing responder simultaneously sends and receives single-base sensing measurement frames to sense the environment, and then sends DMG sensing measurement report frames (sensing measurement report frames) to the sensing initiator in sequence.

[0322] It should be noted that in Figures 26 and 27, the grids above the horizontal line corresponding to the perception initiator or the perception responder represent frames sent by the device, and the grids below the horizontal line (blank grids) represent frames received by the device, and the sent frames and the received frames are corresponding. For the grid directly above the horizontal line corresponding to the perception responder, it represents a frame sent and received by the perception responder, such as a single-base perception measurement frame sent and received by the perception responder. For example, in Figure 26, the perception initiator sends an RQ to the perception responder STA A (indicated by the grid above the horizontal line corresponding to the perception initiator), and accordingly, the perception responder STA A will receive the RQ (indicated by the blank grid below the horizontal line corresponding to the perception responder STA A). The meaning of the blank grids in other figures of this application can be referred to the above description and will not be repeated here.

[0323] Introduction to the DMG perception request frame:

[0324] Figure 28 is a schematic diagram of the format of a DMG perception request frame provided by the related art. The perception request frame includes a MAC frame header, a MAC frame body, and a frame check field. The MAC frame header includes the following: a frame control field, a duration field, a receiver address (RA) field, and a transmitter address (TA) field, arranged in sequence.

Length) subfield, Bandwidth) subfield, and Reserved subfield. Among them, the measurement setting ID subfield occupies 8 bits from B0 to B7, the measurement burst ID subfield occupies 8 bits from B8 to B15, the measurement instance sequence number subfield occupies 8 bits from B16 to B23, the perception type subfield occupies 3 bits from B24 to B26, the STA ID subfield occupies 3 bits from B27 to B29, the first beam index subfield occupies 8 bits from B30 to B37, the number of STAs in the instance subfield occupies 3 bits from B38 to B40, the number of PPDUs in the instance subfield occupies 2 bits from B41 to B42, the EDMG TRN length subfield occupies 8 bits from B43 to B50, the number of RX TRN-Units per TX TRN-Unit subfield occupies 8 bits from B51 to B58, the EDMG TRN-Unit P subfield occupies 2 bits from B59 to B60, the EDMG TRN-Unit M subfield occupies 4 bits from B61 to B64, and the EDMG TRN-Unit The N subfield occupies 2 bits from B65 to B66, the TRN subfield sequence length subfield occupies 2 bits from B67 to B68, the bandwidth subfield occupies 8 bits from B69 to B76, and the reserved subfield occupies 3 bits from B77 to B79.

[0327] The meanings of the fields in the TDD beamforming information field of the DMG perception request frame are as follows:

[0328] • Measurement Setup ID: Identifier of the perception measurement setup associated with this frame.

[0329] • Measurement Burst ID: Identifier of the perception measurement burst associated with this frame.

[0330] Measurement instance number: indicates the number of a sensing measurement instance in a measurement burst.

[0331] Perception Type: Indicates the perception type requested by the frame. For specific values ​​and meanings, see Table 4:

[0332] Table 4

[0334] STA ID: Indicates the order in which a STA participates in a perception measurement instance.

[0335] First beam index: indicates the index of the first transmit beam used in a perception measurement instance.

[0336] Number of STAs in an instance: Indicates the number of STAs participating in a perception measurement instance.

[0337] Number of PPDUs in an instance: Indicates the number of PPDUs that appear in a perception measurement instance.

[0338] EDMG TRN length: indicates the number of TRN units contained in a PPDU.

[0339] Number of RX TRN-Units per TX TRN-Unit: Indicates the number of TRN-Units sent consecutively in the same direction.

[0343] TRN subfield sequence length: indicates the length of the Golay sequence used by each TRN subfield.

[0344] Bandwidth: Indicates the bandwidth used to send the TRN field.

[0345] Since there is no clear definition of the format and length of the single-base PPDU in the parallel mode of collaborative single-base sensing, the single-base PPDU may overlap with the sensing measurement report frame, thereby causing interference, as shown in Figure 29. Figure 29 is a schematic diagram of the process of the parallel mode of collaborative single-base sensing measurement provided by an exemplary embodiment of the present application. The process involves a sensing initiator (STA) and two sensing responders (station A and station B), and includes the following processes (from left to right):

[0346] (1) The perception initiator sends a DMG perception request frame to station A, where the "number of STAs in the instance" is set to 2, the "number of PPDUs" is set to 1, and the "STA ID" is set to 0;

[0347] (2) After SIFS time, site A replies with a DMG sensing response frame to the sensing initiator;

[0348] (3) After SIFS time, the sensing initiator sends a DMG sensing request frame to station B, where the "number of STAs in the instance" is set to 2, the "number of PPDUs" is set to 1, and the "STA ID" is set to 1;

[0349] (4) After SIFS time, site B replies with a DMG sensing response frame to the sensing initiator;

[0350] (5) After the SIFS time, station A and station B simultaneously send and receive a single-base sensing measurement frame to sense the environment;

[0351] (6) After the SIFS time, station A sends a DMG perception measurement report frame to the perception initiator to report the perception measurement results;

[0352] (7) After SIFS, the sensing initiator sends an ACK frame to station A.

[0353] (8) After the SIFS time, the perception initiator sends a DMG perception reporting polling frame to site B, triggering site B to report the perception measurement results;

[0354] (9) After the SIFS time, station B sends a DMG perception measurement report frame to the perception initiator to report the perception measurement results;

[0355] (10) After SIFS time, the sensing initiator replies with an ACK frame to site B.

[0356] It should be noted that (7) and (10) above are optional steps. In the above example, there are only two perception responders. If there are more perception responders, the above method can be used to continue to trigger subsequent perception responders to send DMG perception measurement report frames.

[0357] As shown in Figure 29, in the above process, when the length of the monostatic perception measurement frame (Monostatic PPDU) sent and received by site B is greater than the length of the monostatic perception measurement frame sent and received by site A, the monostatic perception measurement frame sent and received by site B overlaps with the DMG perception measurement report frame sent by site A, thereby causing interference between site A and site B.

[0358] To resolve the problem of interference between site A and site B, a perception measurement method is provided. FIG30 is a flowchart of the perception measurement method provided by an exemplary embodiment of the present application. The method is performed by a perception participating device and includes:

[0359] Step 3010: Send or receive a frame carrying a second field in the collaborative single-base perception process in parallel mode, where the second field is used to indicate duration-related information of the single-base PPDU.

[0360] To solve the problem of interference between site A and site B, this application proposes two solutions:

[0361] Solution 1: The perception responder proactively informs the perception initiator of the duration-related information of the single-base PPDU it uses. The perception initiator selects the appropriate time to send the DMG perception poll frame based on this information and certain rules. For example, perception responders 1 and 2 inform the perception initiator of the duration of the single-base PPDU, t1 and t2, respectively. If t1 is greater than t2, the perception initiator sends the DMG perception poll frame after the SIFS time after the duration t1. For example, the duration-related information of the single-base PPDU in Solution 1 refers to the actual duration information of the single-base PPDU sent by the perception responder.

[0362] In the collaborative single-base sensing process in parallel mode, the sensing response device sends a frame carrying the second field to the sensing initiator device, where the frame is a DMG sensing measurement setting response frame or a DMG sensing response frame;

[0363] In the collaborative single-base perception process in parallel mode, the perception initiating device receives a frame carrying the second field sent by the perception responding device, which is a DMG perception measurement setting response frame or a DMG perception response frame.

[0364] In the embodiment of solution 1, the sensing initiating device selects an appropriate time to send the DMG sensing polling frame according to the following rules:

[0365] In a collaborative single-base perception instance, if the instance is in parallel mode, the perception initiating device must send the first DMG perception polling frame within no more than SIFS time after the longest single-base PPDU is sent to trigger the perception responding device to report the perception measurement results.

[0366] Solution 2: The perception responder passively receives the duration configuration information of the single-base PPDU from the perception initiator, and sends the appropriate single-base PPDU based on this information. At the same time, the perception initiator also selects the appropriate time to send the DMG perception polling frame based on the duration configuration information of these single-base PPDUs. Exemplarily, the duration configuration information of the single-base PPDU of the perception initiator is t3, then the duration of the single-base PPDU sent by perception responder 1 and perception responder 2 cannot exceed t3. Exemplarily, the duration-related information of the single-base PPDU in Solution 2 refers to the maximum sending duration of the single-base PPDU required by the perception initiator, and the actual sending duration of the single-base PPDU sent by the perception responder cannot exceed the maximum sending duration of the single-base PPDU required by the perception initiator.

[0367] In the collaborative single-base sensing process in parallel mode, the sensing initiating device sends a frame carrying the second field to the sensing responding device, where the frame is a DMG sensing measurement setting request frame or a DMG sensing request frame;

[0368] In the collaborative single-base perception process in parallel mode, the perception response device receives a frame carrying the second field sent by the perception initiation device, which is a DMG perception measurement setting request frame or a DMG perception request frame.

[0369] In the embodiment of solution 2, the perception initiator selects the appropriate time to send the DMG perception polling frame according to the following rules:

[0370] In a cooperative single-base sensing instance, if the cooperative single-base sensing instance is in parallel mode, the sensing responder must send a single-base PPDU that meets the requirements according to the relevant configuration information of the sensing initiator;

[0371] In a collaborative single-base perception instance, if the collaborative single-base perception instance is in parallel mode, the perception initiator must send the first DMG perception polling frame within no more than SIFS time after the longest single-base PPDU is sent to trigger the perception responder to report the perception measurement results.

[0372] 2.1 Regarding Option 1:

[0373] During the perception measurement setup phase, the perception responder reports single-base PPDU duration-related information to the perception initiator. In these embodiments, the second field is carried in the DMG perception measurement setup element, specifically, the second field is carried in the coordinated single-base specific configuration optional sub-element of the DMG perception measurement setup element.

[0374] As shown in Figure 31, Figure 31 is a schematic diagram of the element structure of the DMG Perception Measurement Setting element. The DMG Perception Measurement Setting element includes, in order: an element ID field, a length field, an element ID extension field, a measurement setting control field, a reporting type field, an LCI field, a peer location field, and an optional sub-element field.

The subelement ID field occupies 1 byte, the length field occupies 1 byte, and the duration of monostatic PPDUs without TRN field occupies 1, 2, 4, 6, or 8 bytes.

[0381] The sub-element ID is any integer between 4 and 255, with the value 4 being used as an example.

[0382] The length indicates the number of bytes of the element excluding the sub-element ID and length fields.

[0383] The duration of the monostatic PPDU without the TRN field indicates the duration of the monostatic PPDU used by the device in the cooperative monostatic awareness measurement instance (excluding the duration of the TRN field, which is fixed), and the unit is TSF time unit.

[0384] In some embodiments, the second field is the duration field of the single-base PPDU in the coordinated single-base specific configuration optional sub-element, and the coordinated single-base specific configuration optional sub-element further includes: at least one of a sub-element identification field and a length field.

The remaining fields are the same as above and are not repeated here.

[0386] The duration of the monostatic PPDU indicates the duration of the monostatic PPDU used by the device in the coordinated monostatic awareness measurement instance, in TSF time units.

[0387] 2.1.2 Example 2:

[0388] The second field is the data length field in the cooperative single-base specific configuration optional sub-element. For example, in the cooperative single-base specific configuration optional sub-element field, the specific frame format is shown in FIG33.

[0396] The data length indicates the length of the PSDU carried in the monostatic PPDU used by the device in the coordinated monostatic awareness measurement instance, in bytes.

[0397] Basic MCS and Extended SC MCS Indication: The values ​​and meanings of the Basic MCS and Extended SC MCS Indication fields are consistent with those in the L-Header of a single-based PPDU. When the PPDU Type field indicates "EDMG Control Mode PPDU," "EDMG SC Mode PPDU," or "EDMG OFDM Mode PPDU," the Extended SC MCS Indication field is reserved.

[0398] The value and meaning of the Additional EDMG PPDU field are the same as those in the L-Header of a Mono-based PPDU. A value of 1 indicates that another PPDU (without a preamble) follows the Mono-based PPDU immediately, without the need for an SIF interval. A value of 0 indicates that no additional PPDU follows the Mono-based PPDU.

[0399] Number of Spatial Streams: The value and meaning are the same as the Number of Spatial Streams field in the EDMG-Header-A of a Single-Based PPDU.

In one perception measurement setting, each perception responder only needs to transmit information related to the single-base PPDU duration once, and the signaling overhead is small.

[0405] During the sensing measurement instance phase, the sensing responder reports information related to the duration of the monostatic PPDU to the sensing initiator. In these embodiments, the second field is carried in the TDD beamforming field, and the second field is the duration field of the monostatic PPDU in the TDD beamforming field, or the duration field or data length field of the monostatic PPDU after removing the TRN field.
