As used in this disclosure and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0064] It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, such 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 disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. 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."

[0065] First, some terms involved in the embodiments of this application are introduced as follows:

[0066] 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.

[0067] Association Identifier (AID): used to identify a terminal after establishing an association with an access point.

[0068] WLAN devices participating in WLAN awareness may have the following roles:

[0069] Sensing Initiator: Also known as the sensing session initiator, sensing initiating device, or initiator. A sensing initiator is a device that initiates sensing measurements and wants to obtain sensing results.

[0070] Sensing Responder: Also known as Sensing Session Responder, Sensing Responder Device, or Responder. A Sensing Responder is a device that participates in sensing measurements without being the initiating device.

[0071] Sensing Transmitter: Also known as sensing signal sending device, sensing sender, sensing sending device, or transmitter. A sensing signal sender is a device that sends sensing PPDUs.

[0072] Sensing Receiver: Also known as a sensing signal receiving device, sensing receiver, sensing receiving device, or receiver. A sensing signal receiver is a device that receives echo signals. Echo signals are the physical layer protocol data units sent by the sensing signal sender that are scattered and / or reflected by people or objects.

[0073] 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.

[0074] Next, the relevant technical background involved in the embodiments of this application is introduced:

[0075] Figure 1 is a block diagram of a perception measurement system 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 APs and STAs as an example for illustration.

[0076] 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.

[0077] In some embodiments, STAs may include AP STAs and non-AP STAs.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] In the 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 self-driving, in-vehicle communication device, wireless device in remote medical care, wireless device in smart grid, wireless device in transportation safety, wireless device in smart city, wireless device in smart home, wireless communication chip / ASIC / SOC / etc. that supports WLAN / Wi-Fi technology.

[0085] WLAN technology can support frequency bands including but not limited to: low frequency bands (2.4GHz, 5GHz, 6GHz) and high frequency bands (60GHz).

[0086] One or more links exist between a station and an access point.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] In the WLAN sensing scenario, the WLAN terminals involved in sensing include: sensing initiators and sensing responders. Furthermore, sensing responders can be divided into sensing senders and sensing receivers.

[0093] Perception measurement can be applied to cellular network communication systems, wireless local area networks (WLAN) systems, or wireless fidelity networks (Wi-Fi) systems, and this application does not limit this. This application uses the application of perception measurement in WLAN or Wi-Fi systems as an example for schematic illustration.

[0094] 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:

[0095] 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.

[0096] The following describes the millimeter wave sensing process:

[0097] Figure 3 is a schematic diagram of the millimeter wave sensing process provided by an exemplary embodiment of the present application. As shown in Figure 3, the process is a general process of millimeter wave sensing, which includes, from left to right, the session setup phase, the millimeter wave sensing measurement setup (directional multi-gigabit (DMG) Measurement setup) phase, and the sensing measurement phase. The sensing measurement phase consists of multiple sensing measurement bursts, and each burst consists of multiple sensing measurement instances. The time interval between bursts is the inter-burst interval, and the time interval between adjacent sensing measurement instances in a burst is the intra-burst interval. In Figure 3, MACADR refers to the Medium Access Control (MAC) address, AID refers to the association identifier, DMG Measurement setup ID refers to the millimeter wave sensing measurement setup identifier, MS ID refers to the measurement setup (MS) identifier, Burst ID refers to the burst identifier, and Instance Sequential Number (SN) refers to the identifier of the sensing measurement instance, also known as the Sensing Instance SN. The "burst" in the above description can also be called a "burst."

[0098] This article introduces an example of millimeter wave collaborative monostatic sensing measurement:

[0099] Millimeter-wave collaborative monostatic sensing measurement instances exist in two modes: a sequential mode and a parallel mode. For example, Figure 4 is a schematic diagram of an example of a sequential mode for millimeter-wave collaborative monostatic sensing measurement provided by an exemplary embodiment of the present application, and Figure 5 is a schematic diagram of an example of a parallel mode for millimeter-wave collaborative monostatic sensing measurement provided by an exemplary embodiment of the present application.

[0100] As shown in Figures 4 and 5, the similarities between the sequential and parallel modes are that the sensing initiator (Initiator) needs to send a millimeter wave sensing request (DMG Sensing Request) frame to each sensing responder (Responder) at the beginning of the sensing measurement instance, and each sensing responder needs to reply with a millimeter wave sensing response (DMG 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.

[0101] As shown in Figures 4 and 5, the difference between sequential mode and parallel mode is that in sequential mode, each sensing responder sends and receives monostatic sensing measurement frames (Monostatic PPDU) to sense the environment and sends a sensing measurement report frame (DMG Sensing Measurement Report) to the sensing initiator within the SIFS time. In parallel mode, each sensing responder simultaneously sends and receives monostatic sensing measurement frames to sense the environment and then sends DMG sensing measurement report frames (Perception Measurement Report frames) to the sensing initiator.

[0102] It should be noted that in Figures 4 and 5, 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 4, the perception initiator sends an RQ to the perception responder site A (represented by the grid above the horizontal line corresponding to the perception initiator), and accordingly, the perception responder site A will receive the RQ (represented by the blank grid below the horizontal line corresponding to the perception responder site 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.

[0103] The following describes the frame format of the DMG perception measurement setting element:

[0104] Figure 6 is a schematic diagram of the frame format of the DMG sensing measurement setup element provided by an exemplary embodiment of the present application. As shown in Figure 6, the DMG sensing measurement setup element carries information for setting a DMG sensing measurement. The DMG sensing measurement setup element is located in the DMG sensing measurement setup request frame (Sensing Measurement Setup Request) and the DMG sensing measurement setup response frame (Sensing Measurement Setup Response). It includes an element ID field, a length field, an element ID extension field, a measurement setup control field, a report type (Report Type) field, an LCI field, a peer location (Peer Orientation) field, and an optional sub-element field. The measurement setup control field includes the following fields:

A value of 1 indicates that the peer orientation field is present in the DMG Awareness Measurement Setup element; a value of 0 indicates that the peer orientation field is not present in the DMG Awareness Measurement Setup element.

[0113]

[0114] In addition, the LCI field carries the LCI field in the location configuration information report.

[0115] The peer location field is used to indicate the direction and distance of the peer device, and includes three subfields: direction angle (Azimuth), pitch angle (Elevation), and range (Range).

[0116] The optional sub-element field includes zero or more sub-elements. All sub-elements and their order are shown in Table 3 below.

As shown in Figure 7, a TDD beamforming frame is a type of control frame. Its MAC frame body consists of two parts: the TDD beamforming control field and the TDD beamforming information field.

[0128] As shown in Table 4, the TDD beamforming frame type field values ​​0, 1, and 2 all indicate that the TDD beamforming frame is a type related to beam training, which is irrelevant to the method provided in the embodiment of the present application. The value 3 indicates that the TDD beamforming frame is a type related to DMG perception.

[0129] When the value of the TDD beamforming frame type field is 3, the TDD group beamforming (TDD Group Beamforming) field and the TDD beam measurement (TDD Beam Measurement) field jointly indicate the use of a TDD beamforming frame in DMG perception. For specific values ​​and their meanings, please refer to Table 5.

[0152] Introduction to the DMG perception response frame:

[0153] Figure 9 is a schematic diagram of the format of a sensing response frame provided by an exemplary embodiment of the present application. As shown in Figure 9, the MAC frame body of the DMG sensing response frame only includes the TDD beamforming control field.

[0154] Introduction to DMG perception polling frame:

[0155] FIG10 is a schematic diagram of the format of a perception polling frame provided by an exemplary embodiment of the present application. As shown in FIG10 , the meanings of the fields in the TDD beamforming information field of the DMG perception polling frame are as follows:

[0156] Measurement Setup ID: an identifier indicating the awareness measurement setup associated with this DMG awareness poll frame.

[0157] Measurement Burst ID: an identifier indicating the perception measurement burst associated with this DMG perception polling frame.

[0158] Sensing Instance Sequential Number (SN): indicates the identifier of the sensing measurement instance associated with this DMG sensing polling frame.

[0159] Optionally, the specific information implementation in the collaborative single-base sensing process is described in the following three cases.

[0160] Schematically, the perception types of collaborative single-base perception include two modes: sequential collaborative single-base and parallel collaborative single-base. Although the similarities between sequential collaborative single-base and parallel collaborative single-base are that the perception initiator needs to send a DMG perception request frame to each perception responder separately in the initial stage of the perception measurement instance, and each perception responder needs to reply with a DMG Sensing Response frame to the perception initiator within the SIFS time; however, in the sequential collaborative single-base mode, multiple perception responders will successively send and receive monostatic perception measurement frames (Monostatic PPDU) to perceive the environment, and send perception measurement report frames (DMG Sensing Measurement Report) to the perception initiator within the SIFS time; in the parallel collaborative single-base mode, multiple perception responders simultaneously send and receive Monostatic PPDU to perceive the environment, and then send perception measurement report frames to the perception initiator in sequence. That is, the perception type of collaborative single-base perception is implemented in different modes, which will result in differences in the situations in which the perception responders send and receive monostatic perception measurement frames. However, in the related art, no matter in the perception measurement setting stage or in the perception measurement instance stage, there is no field that can more directly and clearly indicate the perception type of cooperative single-base perception.

[0161] Illustratively, during the measurement process of coordinated single-base sensing, there are two modes for reporting coordinated single-base sensing measurements: polling-free and polling-based. However, in related technologies, whether in the sensing measurement setup phase or the sensing measurement instance phase, there is no field that can more directly and clearly distinguish between these two modes, resulting in unclear indication.

[0162] Schematically, the related art does not clearly define the format and length of a single-base PPDU; it simply requires that the receiving address (RA) in the physical layer service data unit (PSDU) carried by the single-base PPDU be equal to the transmitting address (TA). Therefore, interference issues may arise in the parallel mode of cooperative single-base awareness. Specifically, because the length of site B's single-base PPDU is longer than that of site A, site B's single-base PPDU overlaps with site A's Report frame, causing interference between sites A and B.

[0163] Therefore, in the above-mentioned single-base perception measurement method process, after the perception initiator sends a frame to the perception responder, not only can the perception responder not directly read the specific information of the collaborative single-base perception process through field reading, but it is also easy for the perception responder to obtain wrong specific information due to distortion in the transmission process, thereby leading to unclear indication problems.

[0164] The method provided in the embodiment of the present application is that the perception initiator sends a frame carrying a first field to the perception responder. Since the first field is a dedicated field for sequential collaborative single-base or parallel collaborative single-base, and / or has a dedicated meaning in the sequential collaborative single-base or parallel collaborative single-base, according to the difference in the type of the first field, specific problems corresponding to the information content carried by the first field can be solved, such as: being able to distinguish the perception type of collaborative single-base perception, and / or being able to distinguish the polling situation of collaborative single-base perception measurement reporting, and / or being able to limit the maximum length of the single-base PPDU. When the perception responder receives the frame sent by the perception initiator, by reading the fields in the frame, not only the perception accuracy of the perception responder is improved, but also it is convenient for the perception responder to have a more comprehensive understanding and analysis of the collaborative single-base perception measurement process.

[0165] FIG11 is a flowchart of a perception measurement method provided by an exemplary embodiment of the present application, which is applied to a perception measurement device. The perception measurement device includes a perception initiator device (perception initiator) or a perception responder device (perception responder). The perception measurement method is described using the perception initiator as an example. The method includes:

[0166] Step 1102: Send a frame carrying the first field.

[0167] The first field is a dedicated field of the sequential collaboration single base or the parallel collaboration single base, and / or the first field has a dedicated meaning in the sequential collaboration single base or the parallel collaboration single base.

[0168] The above-mentioned perception measurement method is applied to collaborative single-base perception measurement. In the process of collaborative single-base perception measurement, the perception initiator triggers each perception responder participating in the collaboration to execute all or part of the stages in the perception measurement process.

[0169] As shown in Figure 3, a schematic diagram of the millimeter wave sensing process provided by an exemplary embodiment of the present application includes a session establishment phase, a millimeter wave sensing measurement setting phase, and a sensing measurement phase. Among them, the sensing measurement phase consists of multiple sensing measurement bursts (Burst), and each burst consists of multiple sensing measurement instances (DMG Sensing Instance). There are two modes of millimeter wave collaborative single-base sensing measurement instances, one is sequential collaborative single-base (sequential mode type of collaborative single-base), and the other is parallel collaborative single-base (parallel mode type of collaborative single-base).

[0170] Illustratively, the first field is implemented as a proprietary field for indicating that the first field is a newly added field in the frame and is used to carry proprietary information content. For example, at least one first field is added to the perception measurement setup frame; or at least one first field is added to the perception request frame, etc.

[0171] In an illustrative manner, the first field has a proprietary meaning for indicating that the first field is an existing field in the frame, and the value range of the existing field is adjusted, and the proprietary information content carried is represented by the set value; or, the meaning of the existing field is defined in multiple layers, and the proprietary information content can be obtained through the field, etc.

[0172] Optionally, a first frame carrying a perception type field is sent, where the perception type field is used to indicate whether the perception type is sequential collaborative single-base or parallel collaborative single-base. The first frame is at least one of the following frames: a millimeter wave DMG perception measurement setup request frame; a millimeter wave DMG perception measurement setup response frame; or a millimeter wave DMG perception request frame.

[0173] Optionally, a second frame carrying a site identification field is sent, where the site identification field is used to indicate the order in which the sites participate in the sequential cooperative single base. The second frame is a DMG awareness request frame.

[0174] Optionally, a third frame carrying a reporting polling field is sent, where the reporting polling field is used to indicate whether polling is required for reporting the perception measurement results. The third frame is at least one of the following frames: a millimeter wave DMG perception measurement setup request frame; a millimeter wave DMG perception measurement setup response frame; or a millimeter wave DMG perception request frame.

[0175] Optionally, a fourth frame is sent that carries a single-base PPDU maximum duration field, where the single-base PPDU maximum duration field is used to indicate the maximum duration of the single-base PPDU used by the perception responder. The fourth frame is at least one of the following frames: a DMG perception measurement setup request frame; or a DMG perception measurement setup response frame.

[0176] Illustratively, the first field is carried in at least one of the first frame, the second frame, the third frame and the fourth frame.

[0177] Optionally, the frame carries at least one first field, and different types of first fields correspond to different types of information content, and different types of information content can solve different problems.

[0178] Question 1: How to distinguish the perception type of collaborative single-base perception, that is, to distinguish whether it is sequential collaborative single-base or parallel collaborative single-base.

[0179] Question 2: How to distinguish the polling status of cooperative single-base sensing measurement reports, that is, to distinguish whether there is polling or not.

[0180] Question 3: How to limit the length of a single-base PPDU, that is, the maximum length limit of a single-base PPDU.

[0181] In response to the above problem, the perception initiator sends the first field of the corresponding type to solve the above problem.

[0182] Optionally, when implementing the differentiation phase of collaborative single-base perception types, the perception initiator sends a first frame carrying a perception type field, and / or sends a second frame carrying a site identification field, thereby solving the above-mentioned problem one.

[0183] Optionally, when distinguishing the polling situations of the coordinated single-base sensing measurement report, the sensing initiator sends a third frame carrying a reporting polling field, thereby solving the above-mentioned second problem.

[0184] Optionally, when the length of the single-base PPDU is limited, the perception initiator sends a fourth frame carrying the maximum length field of the single-base PPDU, thereby solving the above-mentioned problem three.

[0185] In summary, the method provided in this embodiment involves a sensing initiator sending a frame carrying a first field to a sensing responder. Because the first field is specific to sequential coordinated single-base or parallel coordinated single-base, and / or has a specific meaning within sequential coordinated single-base or parallel coordinated single-base, the difference in type of the first field can resolve at least one of three specific issues related to the information content carried by the first field: for example, differentiating the sensing type of coordinated single-base sensing, differentiating the polling status of coordinated single-base sensing measurement reports, and / or limiting the maximum length of a single-base PPDU. This facilitates the sensing responder's more comprehensive understanding and analysis of the coordinated single-base sensing measurement process.

[0186] Schematically, based on the perception initiator sending a frame carrying the above-mentioned different types of first fields to the perception responder, the perception initiator can achieve the purpose of conveying different information to the perception responder. As shown in Figure 12, it is a flowchart of a perception measurement method provided by an exemplary embodiment of the present application. The method is applied to a perception measurement device. Among them, the perception measurement device includes a perception initiator device (perception initiator) or a perception response device (perception responder). Schematically, the method is described as being executed by a perception responder. The method includes:

[0187] Step 1202: Receive a frame carrying a first field.

[0188] The first field is a dedicated field of the sequential collaboration single base or the parallel collaboration single base, and / or the first field has a dedicated meaning in the sequential collaboration single base or the parallel collaboration single base.

[0189] The above-mentioned perception measurement method is applied to collaborative single-base perception measurement. In the collaborative single-base perception measurement process, the perception initiator triggers each participating perception responder to execute all or part of the perception measurement process. In the collaborative single-base perception measurement process, the perception initiator triggers each participating perception responder to execute all or part of the perception measurement process.

[0190] For example, in a sequential collaborative single base, the request phase includes the steps of the perception initiator sending a perception request frame to the perception responder and the perception responder sending a perception response frame to the perception initiator, the perception measurement phase includes the step of the perception responder sending a single-base perception measurement frame, and the reporting phase includes the step of the perception responder sending a perception measurement report frame to the perception initiator; in a parallel collaborative single base, the request phase includes the step of the perception initiator sending a perception request frame to the perception responder and the perception responder sending a perception response frame to the perception initiator, the perception measurement phase includes the step of the perception responder sending a single-base perception measurement frame, and the reporting phase includes the step of the perception responder sending a perception measurement report frame to the perception initiator.

[0191] Optionally, a first frame carrying a perception type field is received, where the perception type field is used to indicate whether the perception type is sequential collaborative single-base or parallel collaborative single-base. The first frame is at least one of the following frames: a millimeter-wave DMG perception measurement setup request frame; a millimeter-wave DMG perception measurement setup response frame; or a millimeter-wave DMG perception request frame.

[0192] Optionally, a second frame carrying a site identification field is received, where the site identification field is used to indicate the order in which the sites participate in the sequential cooperative single base. The second frame is a DMG awareness request frame.

[0193] Optionally, a third frame carrying a reporting polling field is received, and the reporting polling field is used to indicate whether reporting of the perception measurement result requires polling. The third frame is at least one of the following frames: a millimeter wave DMG perception measurement setting request frame; a millimeter wave DMG perception measurement setting response frame; or a millimeter wave DMG perception request frame.

[0194] Optionally, a fourth frame carrying a maximum duration field for a single-base PPDU is received, where the maximum duration field for the single-base PPDU is used to indicate the maximum duration of the single-base PPDU used by the sensing responder. The fourth frame is at least one of the following frames: a DMG sensing measurement setup request frame; or a DMG sensing measurement setup response frame.

[0195] Illustratively, the first field is carried in at least one of the first frame, the second frame, the third frame and the fourth frame.

[0196] In summary, the method provided in this embodiment, because the frame sent by the perception initiator to the perception responder carries a first field, and the first field is a field specific to sequential collaborative single-base or parallel collaborative single-base, can resolve at least one of three specific issues related to the information content carried by the first field, depending on the type of the first field. Upon receiving the frame sent by the perception initiator, the perception responder can distinguish the perception type of collaborative single-base perception, and / or distinguish the polling status of the collaborative single-base perception measurement report, and / or limit the maximum length of the single-base PPDU. This not only improves the perception accuracy of the perception responder, but also enables the perception responder to gain a more comprehensive understanding and analysis of the collaborative single-base perception measurement process based on reading the first field.

[0197] Regarding the above question 1:

[0198] In the related art, the collaborative single-base perception type includes two modes: sequential collaborative single-base and parallel collaborative single-base. However, neither in the DMG perception measurement setting element nor in the DMG perception request frame, there is a field to accurately distinguish the sequential mode type and parallel mode type in collaborative single-base perception. Therefore, there is a problem of unclear indication of sequential collaborative single-base and parallel collaborative single-base.

[0199] Using the perception measurement method provided in the embodiment of the present application, when distinguishing the perception type of collaborative single-base perception, the format of the millimeter wave DMG perception measurement setting frame and / or the millimeter wave DMG perception measurement setting frame is improved so that it carries the first field.

[0200] In an optional embodiment, the sensing initiator sends a first frame carrying a sensing type field; the sensing responder receives the first frame carrying the sensing type field.

[0201] Among them, the perception type field is used to indicate that the perception type is a sequential collaborative single base or a parallel collaborative single base, and the perception type field is used as a representation of the first field.

[0202] Illustratively, the perception type indicates the mode type of the collaborative single-base, i.e., whether the collaborative single-base belongs to a sequential collaborative single-base or a parallel collaborative single-base. The first frame carries the perception type field, so by reading the first frame, it can be determined whether the first frame belongs to a sequential collaborative single-base or a parallel collaborative single-base.

[0203] In an optional embodiment, the first frame is at least one of the following frames: a DMG perception measurement setting request frame; a DMG perception measurement setting response frame; and a DMG perception request frame.

[0204] Among them, the DMG perception measurement setting request frame and the perception measurement setting response frame are the types of frames in the perception measurement setting phase; and the DMG perception request frame is the type of frame in the perception measurement instance phase.

[0205] Schematically, the DMG perception measurement setting request frame is used to indicate the frame sent by perception measurement device A to perception measurement device B during the perception measurement setting stage; the DMG perception measurement setting response frame is used to indicate the frame sent by perception measurement device B to perception measurement device A during the perception measurement setting stage. For example: take the case where perception measurement device A is implemented as a perception initiator and perception measurement device B is implemented as a perception responder as an example for explanation. The perception initiator sends a DMG perception measurement setting request frame to the perception responder, and the perception responder selectively sends a DMG perception measurement setting response frame to the perception initiator based on the DMG perception measurement setting request frame sent by the perception initiator. For example: when the DMG perception measurement setting request frame sent by the perception initiator does not meet the reception requirements of the perception responder, the perception responder sends a DMG perception measurement setting response frame to the perception initiator.

[0206] Optionally, since the DMG perception measurement setting request frame and the DMG perception measurement setting response frame are both types of frames in the perception measurement setting stage, the DMG perception measurement setting frame is used to indicate the frames in the perception measurement setting stage, which include the DMG perception measurement setting request frame and the DMG perception measurement setting response frame in the perception measurement setting stage, thereby performing the following description process of character adjustment in the perception measurement setting stage.

[0207] Illustratively, the following description is made by taking the first frame implemented as the above-mentioned different types of frames as an example.

[0208] In an optional embodiment, the first frame is implemented as a DMG awareness measurement setting frame (DMG awareness measurement setting request frame, or DMG awareness measurement setting response frame).

[0209] Schematically, as shown in FIG6 , a diagram of the format of a DMG perception measurement setting frame (DMG perception measurement setting request frame or DMG perception measurement setting response frame) is shown. The frame includes a measurement setting control field, and under the measurement setting control field, a perception type subfield is included, which is used to indicate the type of the DMG perception measurement.

[0210] Optionally, the perception measurement method provided in an embodiment of the present application is used to modify the perception type subfield under the measurement setting control field in the DMG perception measurement setting frame. As shown in Figure 13, the perception type subfield (in bold) under the measurement setting control field in the DMG perception measurement setting frame shown in Figure 6 is modified to obtain a perception type subfield. The value of the perception type subfield can be used to determine the perception type under the coordinated single base.

[0211] For example, the specific values ​​and meanings of the perception type subfield are shown in Table 7 below.

[0212] Table 7

[0213] Value Meaning 0 Sequential Coordinated Monostatic 1 Parallel Coordinated Monostatic 2 Coordinated Bistatic 3 Bistatic 4 Multistatic 5-7 Reserved

[0214] Among them, when the value of the perception type subfield is 0, it means that the type of DMG perception measurement is a sequential collaborative single-base type; when the value of the perception type subfield is 1, it means that the DMG perception type is a parallel collaborative single-base type; when the value of the perception type subfield is 2, it means that the DMG perception type is a collaborative dual-base type; when the value of the perception type subfield is 3, it means that the DMG perception type is a dual-base type; when the value of the perception type subfield is 4, it means that the DMG perception type is a multi-base type.

[0215] That is: when the value of the perception type subfield is 0, the DMG perception type under the collaborative single base is determined to be a sequential collaborative single base; when the value of the perception type subfield is 1, the DMG perception type under the collaborative single base is determined to be a parallel collaborative single base.

[0216] It is worth noting that the specific values ​​of the above-mentioned perception type subfield are only illustrative examples. The values ​​of the perception type subfield can also adopt other setting schemes, for example: setting the value to 0 to represent a sequential collaborative single base; setting the value to 4 to represent a parallel collaborative single base; or setting the value to 4 to represent a sequential collaborative single base; setting the value to 0 to represent a parallel collaborative single base, etc. The embodiments of the present application do not limit this.

[0217] In addition, the meanings of the above-mentioned sequential collaborative single base and parallel collaborative single base are only illustrative examples. For example, the sequential collaborative single base can also be called the sequential mode of the collaborative single base; the parallel collaborative single base can also be called the parallel mode of the collaborative single base, etc. The embodiments of this application do not limit this.

[0218] Optionally, the perception type subfield is used as the first field, and the first field carries the perception type field; or, the measurement setting control field corresponding to the perception type subfield is used as the first field, and the first field carries the perception type field.

[0219] In an embodiment of the present application, the perception type subfield under the measurement setting control field in the perception measurement setting frame is adjusted. Through the value of the perception type subfield, the mode type of the collaborative single base can be distinguished more accurately, that is, it can be determined more quickly whether it belongs to a sequential collaborative single base or a parallel collaborative single base.

[0220] In an optional embodiment, the first frame is implemented as a DMG awareness request frame.

[0221] 8 , which is a schematic diagram of the format of a DMG perception request frame, includes a TDD beamforming information field, which includes a perception type subfield, which is used to indicate the type of DMG perception measurement.

[0222] Optionally, the perception measurement method provided in an embodiment of the present application is used to modify the perception type subfield under the TDD beamforming information field in the DMG perception request frame. As shown in Figure 14, the perception type subfield (in bold) under the TDD beamforming information field in the DMG perception request frame shown in Figure 8 is modified to obtain a perception type subfield. The value of the perception type subfield can be used to determine the perception type under cooperative single-base.

[0223] For example, the specific values ​​and meanings of the perception type subfield are shown in Table 8 below.

[0224] Table 8

[0225] Value Meaning 0 Sequential Coordinated Monostatic 1 Parallel Coordinated Monostatic 2 Coordinated Bistatic 3 Multistatic 4-7 Reserved

[0226] Among them, when the value of the perception type subfield is 0, it means that the DMG perception type is sequential collaborative single base; when the value of the perception type subfield is 1, it means that the DMG perception type is parallel collaborative single base; when the value of the perception type subfield is 2, it means that the DMG perception type is collaborative dual base; when the value of the perception type subfield is 3, it means that the DMG perception type is multi-base.

[0227] That is: when the value of the perception type subfield is 0, the DMG perception type under the collaborative single base is determined to be a sequential collaborative single base; when the value of the perception type subfield is 1, the DMG perception type under the collaborative single base is determined to be a parallel collaborative single base.

[0228] Schematically, as shown in Table 7 above, in the perception measurement setting phase (perception measurement setting request frame, or, perception measurement setting response frame), the perception type subfield takes a value of 3 to indicate that the perception type is a dual-base type; in the perception measurement instance phase (DMG perception request frame), the case where the perception type is a dual-base type is indicated by other frames or other fields, so the dual-base type is not included in Table 8 above. The above is only an illustrative example, and the embodiments of the present application are not limited to this.

[0229] Optionally, the perception type subfield is used as the first field, and the first field carries the perception type field; or, the TDD beamforming information field corresponding to the perception type subfield is used as the first field, and the first field carries the perception type field.

[0230] It is worth noting that the specific values ​​of the above-mentioned perception type subfield are only illustrative examples. The values ​​of the perception type subfield can also adopt other setting schemes, for example: setting the value to 0 to represent a sequential collaborative single base; setting the value to 7 to represent a parallel collaborative single base; or setting the value to 4 to represent a sequential collaborative single base; setting the value to 5 to represent a parallel collaborative single base, etc. The embodiments of the present application do not limit this.

[0231] In addition, the meanings of the above-mentioned sequential collaborative single base and parallel collaborative single base are only illustrative examples. For example, the sequential collaborative single base can also be called the sequential mode of the collaborative single base; the parallel collaborative single base can also be called the parallel mode of the collaborative single base, etc. The embodiments of this application do not limit this.

[0232] In an embodiment of the present application, the perception type subfield under the measurement setting control field in the perception measurement setting frame is adjusted. Through the value of the perception type subfield, the mode type of the collaborative single base can be distinguished more accurately, that is, it can be determined more quickly whether it belongs to a sequential collaborative single base or a parallel collaborative single base.

[0233] In an optional embodiment, a second frame carrying a site identification field is sent.

[0234] The site identification field is used to indicate the order in which the sites participate in the sequential collaborative single base.

[0235] Schematically, different STAs (stations) have their corresponding identifiers. When the cooperative single-base is implemented in a sequential cooperative single-base mode, different STAs have different corresponding sending orders, and the different sending orders are represented by the station identification field.

[0236] That is, by reading multiple site identification fields, the transmission order of different STAs in the sequential cooperative single-base mode can be determined.

[0237] In an optional embodiment, the first frame is implemented as a DMG perception request frame; the second frame is implemented as a DMG perception request frame.

[0238] The first frame and the second frame are implemented as the same frame.

[0239] Schematically, as shown in Figure 8, a diagram of the format of a DMG perception request frame is shown. It includes a TDD beamforming information field, which includes a perception type subfield and an STA ID subfield. The perception type subfield is used to indicate the type of DMG perception measurement; the STA ID subfield is used to indicate the identifier of the SAT.

[0240] Optionally, the perception measurement method provided in an embodiment of the present application is used to modify the perception type subfield and STA ID subfield under the TDD beamforming information field in the DMG perception request frame. As shown in Figure 15, the perception type subfield (bold) and STA ID subfield (bold) under the TDD beamforming information field in the DMG perception request frame shown in Figure 8 are modified to obtain the perception type subfield and the STA ID subfield. The perception type under the collaborative single base can be determined by the value of the perception type subfield and the value of the STA ID subfield.

[0241] For example, the specific values ​​and meanings of the Perception Type subfield are shown in Table 8. That is, when the value of the Perception Type subfield is 0, the DMG perception type under the collaborative single base is determined to be sequential collaborative single base; when the value of the Perception Type subfield is 1, the DMG perception type under the collaborative single base is determined to be parallel collaborative single base.

[0242] Optionally, the STA ID subfield is processed differently based on the perception type subfield.

[0243] Illustratively, when the sensing type in the DMG sensing request frame (first frame) is sequential collaborative single-base, the station identification field is used to indicate the order in which stations participate in sequential collaborative single-base.

[0244] In an illustrative manner, when the value of the perception type subfield is 3, the type of DMG perception measurement is multi-base (Multistatic), which indicates that the STA receives the index of the synchronization subfield in the EDMG Multistatic Sensing PPDU; when the value of the perception type subfield is 2, the type of DMG perception measurement is coordinated bistatic (Coordinated Bistatic), then the STA ID subfield represents the identifier of the STA, and also indicates the order in which the STA participates in the perception measurement; when the value of the perception type subfield is 1, the type of DMG perception measurement is parallel collaborative single-base, then the STA ID subfield represents the identifier of the STA; when the value of the perception type subfield is 0, it represents that the type of DMG perception measurement is sequential collaborative single-base, and it is determined that the STA ID subfield represents the identifier of a STA, and also indicates the order in which the STA participates in the perception measurement.

[0245] Optionally, the perception type subfield and the STA ID subfield are used as the first field, and the first field carries the perception type field; or, the TDD beamforming information field corresponding to the perception type subfield and the STA ID subfield is used as the first field, and the first field carries the perception type field.

[0246] It is worth noting that the specific values ​​of the above-mentioned perception type subfield are only illustrative examples. The value of the perception type subfield can also adopt other setting schemes, which are not limited in the embodiments of the present application.

[0247] In an embodiment of the present application, the perception type subfield and the STA ID subfield under the measurement setting control field in the perception measurement setting frame are adjusted. Through the value of the perception type subfield, the mode type of the collaborative single base can be distinguished more accurately. The STA ID subfield can also be used to determine the STA identifier and the order in which the STA participates in perception, so that the perception responder can have a more comprehensive understanding of the content information during the perception measurement process.

[0248] In an optional embodiment, the second frame is implemented as a DMG awareness request frame.

[0249] 8 is a schematic diagram of the format of a DMG perception request frame, which includes a TDD beamforming information field, and the TDD beamforming information field includes a STA ID subfield, which is used to indicate the identifier of the SAT.

[0250] Optionally, the perception measurement method provided in an embodiment of the present application is used to modify the STA ID subfield under the TDD beamforming information field in the DMG perception request frame. As shown in Figure 16, the STA ID subfield (in bold) under the TDD beamforming information field in the DMG perception request frame shown in Figure 8 is modified to obtain the STA ID subfield. The value of the STA ID subfield can be used to determine the perception type under collaborative single-base.

[0251] Optionally, the STA ID subfield is processed differently based on the perception type subfield.

[0252] Illustratively, when the Perception Type field in the DMG Perception Request frame indicates Collaborative Single-base, the value of the Site Identification field falls within the first range and is used to indicate Sequential Collaborative Single-base. The value of the Site Identification field is also used to indicate the order in which the stations participate in the Sequential Collaborative Single-base. The STA ID subfield indicates the site identification character.

[0253] Schematically, in the schematic diagram of the format of the DMG perception request frame shown in FIG16 , the perception type requested by the frame is determined according to the value of the perception type shown in Table 6 above.

[0254] Optionally, after determining the perception type requested by the frame according to the value of the perception type, the STA ID subfield is processed differently.

[0255] Indicatively, when the value of the perception type is 2, it is determined that the perception type requested by the frame is multi-base, which indicates that the STA receives the index of the synchronization subfield in the EDMG Multistatic Sensing PPDU; when the value of the perception type is 1, it is determined that the perception type requested by the frame is collaborative dual-base, and the STA ID subfield represents the identifier of the STA and also indicates the order in which the STA participates in the perception measurement; when the value of the perception type is 0, it is determined that the perception type requested by the frame is collaborative single-base.

[0256] Illustratively, when the perception type field in the DMG perception request frame indicates a coordinated single-base, the value of the site identifier field belongs to the second range to indicate a parallel coordinated single-base.

[0257] Optionally, when the value of the perception type is 0 and the value range of the STA ID subfield is 1-7, the site identification field is used to indicate the order in which the site participates in the sequential collaborative single base; when the value of the perception type is 0 and the value range of the STA ID subfield is 0, the site identification field is used to indicate that the site participates in the parallel collaborative single base mode.

[0258] Optionally, when the value of the sensing type is 0, the sensing type requested by the frame is coordinated single-base. At this time, the mode type of coordinated single-base is determined according to the value difference of the STA ID subfield.

[0259] In principle, when the value of the perception type is 0 and the value range of the STA ID subfield is 1-7, it indicates that the mode type of the collaborative single base is a sequential collaborative mode type. At this time, the STA ID subfield not only represents the identifier of the STA, but also indicates the order in which the STA participates in the perception measurement.

[0260] Illustratively, when the value of the perception type is 0 and the value of the STA ID subfield is 0, it indicates that the mode type of the collaborative single-base is a parallel collaborative mode type.

[0261] It is worth noting that the specific values ​​of the above-mentioned perception types are only illustrative examples. The values ​​of the perception types can also adopt other setting schemes, which are not limited in the embodiments of the present application.

[0262] In an embodiment of the present application, the STA ID subfield in the perception request frame is adjusted. Through the value range of the STA ID subfield, not only the mode type of the collaborative single base can be determined, but also the STA identifier and the order in which the STA participates in perception can be selectively determined based on the mode type of the collaborative single base and the value range of the STA ID subfield, so that the perception responder can have a more comprehensive understanding of the content information in the perception measurement process.

[0263] Regarding the second question above:

[0264] In the related art, there are two methods for reporting coordinated single-base sensing measurements: without polling and with polling. However, neither the DMG Sensing Measurement Setup element nor the DMG Sensing Request frame has a field to accurately determine the polling status in coordinated single-base sensing, resulting in unclear indication of the polling status.

[0265] Using the perception measurement method provided in the embodiment of the present application, when distinguishing the polling situation of collaborative single-base perception reporting, the format of the millimeter wave DMG perception measurement setting frame and / or the millimeter wave DMG perception measurement setting frame is improved so that the sent frame carries the first field.

[0266] In an optional embodiment, the sensing initiator sends a third frame carrying a reporting polling field; and the sensing responder receives the third frame carrying the reporting polling field.

[0267] The report polling field is used to indicate whether reporting of the perception measurement result requires polling, and the report polling field is used as a representation of the first field.

[0268] Illustratively, polling is used to indicate the reporting status of the perception measurement results. The report polling field can indicate two situations, namely: the report polling field indicates that the reporting of the perception measurement results requires polling; or the report polling field indicates that the reporting of the perception measurement results does not require polling.

[0269] The third frame carries a reporting polling field, so by reading the third frame, the polling status of the reporting of the perception measurement result in the third frame can be determined, such as: after reading the third frame, it is determined that the reporting of the perception measurement result needs to be polled; or, after reading the third frame, it is determined that the reporting of the perception measurement result does not need to be polled.

[0270] In an optional embodiment, the third frame is at least one of the following frames: a DMG perception measurement setting request frame; a DMG perception measurement setting response frame; and a perception request frame.

[0271] Optionally, since the DMG perception measurement setting request frame and the DMG perception measurement setting response frame are both types of frames in the perception measurement setting stage, the DMG perception measurement setting frame is used to indicate the frames in the perception measurement setting stage, which include the DMG perception measurement setting request frame and the DMG perception measurement setting response frame in the perception measurement setting stage, thereby performing the following description process of character adjustment in the perception measurement setting stage.

[0272] In an optional embodiment, the third frame is implemented as a DMG perception measurement setting frame (DMG perception measurement setting request frame, or, DMG perception measurement setting response frame), and the reporting polling field is carried in the perception measurement setting element of the DMG perception measurement setting frame (DMG perception measurement setting request frame, or, DMG perception measurement setting response frame).

[0273] Schematically, as shown in Figure 6, a diagram of the format of a DMG perception measurement setting frame (DMG perception measurement setting request frame; DMG perception measurement setting response frame) includes 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.

[0274] Optionally, the perception measurement method provided in the embodiment of the present application is used to modify the field composition in the DMG perception measurement setting frame, and a new field is added to the DMG perception measurement setting frame.

[0275] Schematically, as shown in FIG17, the format of the DMG perception measurement setting frame shown in FIG6 is adjusted, and a report polling field (Report Poll) is added after the report type field, wherein the report polling field is represented by a bold state, and the report polling field indicates whether the reporting of the perception measurement result in a DMG perception measurement setting requires polling. After the format of the DMG perception measurement setting frame is adjusted, a report polling field is added after the report type field, so that the format of the DMG perception measurement setting frame is implemented as follows: element ID field, length field, element ID extension field, measurement setting control field, report type field, report poll field, LCI field, peer location field, and optional sub-element field.

[0276] Among them, whether polling is required for reporting the perception measurement result under the coordinated single base can be determined by the value of the reporting polling field in the DMG perception measurement setting frame.

[0277] In an illustrative manner, when the value of the reporting polling field in the DMG perception measurement setting frame is 1, it indicates that the reporting of the perception measurement results under the collaborative single base needs to be polled; when the value of the reporting polling field in the DMG perception measurement setting frame is 0, it indicates that the reporting of the perception measurement results under the collaborative single base does not need to be polled.

[0278] Alternatively, when the value of the reporting polling field in the DMG perception measurement setting frame is 0, it indicates that the reporting of the perception measurement results under the collaborative single base needs to be polled; when the value of the reporting polling field in the DMG perception measurement setting frame is 1, it indicates that the reporting of the perception measurement results under the collaborative single base does not need to be polled.

[0279] It is worth noting that the specific values ​​of the above-mentioned reporting polling fields are only illustrative examples; the names of the reporting polling fields are only illustrative examples; the positions of the reporting polling fields in the DMG perception measurement setting frame are also only illustrative examples, and there may be different situations.

[0280] For illustration, the position of the Report Polling field in the DMG Awareness Measurement Setup frame is used as an example for description. The Report Polling field is added after the Measurement Setup Control field in the DMG Awareness Measurement Setup frame; alternatively, the Report Polling field is added after the Opposite End Location field in the DMG Awareness Measurement Setup frame. The above examples are merely illustrative and are not intended to limit the present invention.

[0281] In an embodiment of the present application, the format of the DMG perception measurement setting frame is adjusted, and a reporting polling field is added, so that whether the reporting of the perception measurement results under the collaborative single base requires polling is more directly determined according to the value of the reporting polling field.

[0282] In an optional embodiment, the third frame is implemented as a DMG perception measurement setting frame (DMG perception measurement setting request frame, or, DMG perception measurement setting response frame), and the reporting polling field is carried in the optional sub-element field of the DMG perception measurement setting frame (DMG perception measurement setting request frame, or, DMG perception measurement setting response frame).

[0283] Figure 6 illustrates the format of a DMG Sensing Measurement Setup frame. This frame includes an Element ID field, a Length field, an Element ID Extension field, a Measurement Setup Control field, a Reporting Type field, an LCI field, a Peer Location field, and an Optional Sub-Element field. As shown in Table 3 above, the Optional Sub-Element field contains zero or more sub-elements, including the TX Beam List, RX Beam List, and DMG Sensing Scheduling sub-elements.

[0284] Optionally, the perception measurement method provided in the embodiment of the present application is used to adjust the optional sub-elements under the optional sub-element field in the DMG perception measurement setting frame, and add a new sub-element field in the optional sub-element field.

[0285] Schematically, as shown in Figure 18, the optional sub-elements under the optional sub-element field in the DMG perception measurement setting frame shown in Figure 6 are adjusted, wherein the optional sub-element field in the DMG perception measurement setting frame is represented in bold; as shown in Table 9 below, a new coordinated monostatic specific configuration optional sub-element field (Coordinated Monostatic Specific Configuration) is added to the optional sub-element field, wherein the coordinated monostatic specific configuration sub-element field is represented in bold, and the coordinated monostatic specific configuration optional sub-element field is used to carry extended configuration information.

[0286] Table 9

[0287] Sub-element ID Sub-element Name Scalability 1 TX beam list Yes 2 RX beam list Yes 3 DMG-aware scheduling Yes 4 Cooperative single-base specific configuration Yes 5-255 Reserved No

[0288] In the collaborative single-base specific configuration optional sub-element field, the specific frame format is shown in Figure 19. The collaborative single-base specific configuration optional sub-element field includes a sub-element ID, a length, and a report polling field. The sub-element ID value range is any integer between 4 and 255, and the above sub-element ID value of 4 is only an illustrative example; the length indicates the number of bytes in the collaborative single-base specific configuration optional sub-element field excluding the sub-element ID and length fields; the report polling field indicates whether the reporting of the perception measurement results in a DMG perception measurement setting requires polling.

[0289] After adjusting the format of the DMG perception measurement setting frame, a collaborative single-base specific configuration optional sub-element field is added to the optional sub-element type. By taking the value of the reporting polling field under the collaborative single-base specific configuration optional sub-element field, it is possible to determine whether polling is required for reporting the perception measurement results under the collaborative single-base.

[0290] Indicatively, when the value of the reporting polling field under the collaborative single-base specific configuration optional sub-element field is 1, it indicates that the reporting of the perception measurement results under the collaborative single base needs to be polled; when the value of the reporting polling field under the collaborative single-base specific configuration optional sub-element field is 0, it indicates that the reporting of the perception measurement results under the collaborative single base does not need to be polled.

[0291] Alternatively, when the value of the reporting polling field under the collaborative single-base specific configuration optional sub-element field is 0, it indicates that the reporting of the perception measurement results under the collaborative single base needs to be polled; when the value of the reporting polling field under the collaborative single-base specific configuration optional sub-element field is 1, it indicates that the reporting of the perception measurement results under the collaborative single base does not need to be polled.

[0292] It is worth noting that the specific values ​​of the above-mentioned collaborative single-base specific configuration optional sub-element fields are only illustrative examples. The values ​​of the collaborative single-base specific configuration optional sub-element fields can also adopt other setting schemes, which are not limited by the embodiments of this application. In addition, the names of the above-mentioned collaborative single-base specific configuration and collaborative single-base specific configuration optional sub-element fields are only illustrative examples and are not limited by the embodiments of this application.

[0293] In an embodiment of the present application, the format of the DMG perception measurement setting frame is adjusted, the optional sub-elements under the existing optional sub-element field are adjusted, and a reporting polling field is added to the optional sub-element, so that according to the value of the reporting polling field, it is more directly determined whether the reporting of the perception measurement results under the collaborative single base requires polling.

[0294] In an optional embodiment, the third frame is implemented as a DMG awareness request frame.

[0295] Optionally, the reporting polling field is carried in the TDD beam information field of the DMG perception request frame.

[0296] Schematically, as shown in FIG8, a schematic diagram of the format of the DMG perception request frame is shown. It includes a TDD beamforming information field, and the TDD beamforming information field is adjusted so that the report polling field is carried in the TDD beam information field of the DMG perception request frame. As shown in FIG20, after the bandwidth subfield under the TDD beamforming information field in the DMG perception request frame shown in FIG8, a report polling field (in bold) is added to obtain the TDD beamforming information field, that is, the TDD beamforming information field includes the report polling field.

[0297] The reporting polling field indicates whether reporting of the perception measurement result in a DMG perception measurement setting requires polling.

[0298] Indicatively, when the value of the reporting polling field under the TDD beamforming information field is 1, it indicates that the reporting of the perception measurement results under the collaborative single base needs to be polled; when the value of the reporting polling field under the TDD beamforming information field is 0, it indicates that the reporting of the perception measurement results under the collaborative single base does not need to be polled.

[0299] Alternatively, when the value of the reporting polling field under the TDD beamforming information field is 0, it indicates that the reporting of the perception measurement results under the collaborative single base needs to be polled; when the value of the reporting polling field under the TDD beamforming information field is 1, it indicates that the reporting of the perception measurement results under the collaborative single base does not need to be polled.

[0300] In an embodiment of the present application, the format of the DMG perception request frame is adjusted, and a reporting polling field is added after the bandwidth subfield under the TDD beamforming information field, so that according to the value of the reporting polling field, it is more directly determined whether the reporting of the perception measurement results under the collaborative single base requires polling.

[0301] Regarding the third question above:

[0302] Related technologies cannot accurately indicate the length of a monostatic PPDU in cooperative monostatic sensing in parallel mode. Generally, the format and length of a monostatic PPDU are not clearly defined; it is usually sufficient to simply require that the receiving address in the PSDU carried by the monostatic PPDU be equal to the transmitting address. Therefore, in cooperative monostatic sensing parallel mode, interference issues such as those shown in Figure 21 may sometimes occur.

[0303] Figure 21 is a flow chart of a parallel mode of collaborative single-base sensing measurement provided by an exemplary embodiment of the present application. As shown in Figure 21, the process involves one sensing initiator (STA) and two sensing responders (station A and station B), and includes the following steps (from left to right):

[0304] (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;

[0305] (2) After SIFS time, site A replies with a DMG sensing response frame to the sensing initiator;

[0306] (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;

[0307] (4) After SIFS time, site B replies with a DMG perception response frame to the Initiator;

[0308] (5) After the SIFS time, station A and station B simultaneously send and receive a single-base sensing measurement frame to sense the environment;

[0309] (6) After the SIFS time, station A sends a DMG perception measurement report frame to the perception initiator to report the perception measurement results;

[0310] (7) After SIFS time, the sensing initiator replies with an ACK frame to site A;

[0311] (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;

[0312] (9) After the SIFS time, station B sends a DMG perception measurement report frame to the perception initiator to report the perception measurement results;

[0313] (10) After SIFS time, the sensing initiator replies with an ACK frame to site B.

[0314] It should be noted that (7) and (10) above are optional steps. In the above example, there are only two Responders. If there are more Responders, the above method can be used to continue to trigger subsequent Responders to send DMG perception measurement report frames.

[0315] As shown in Figure 21, 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.

[0316] By adopting the perception measurement method provided in the embodiment of the present application, when displaying the maximum length of the single-base PPDU, the format of the millimeter wave DMG perception measurement setting frame is improved so that the sent frame carries the first field.

[0317] In an optional embodiment, the sensing initiator sends a fourth frame carrying the maximum duration field of the single-base PPDU; the sensing responder sends a fourth frame carrying the maximum duration field of the single-base PPDU.

[0318] The maximum duration field of the Mono-based PPDU is used to indicate the maximum duration of the Mono-based PPDU used by the sensing responder, and the maximum duration field of the Mono-based PPDU is used as a representation of the first field. The fourth frame carries the maximum duration field of the Mono-based PPDU, so by reading the fourth frame, the maximum duration field of the Mono-based PPDU in the fourth frame can be determined.

[0319] In an optional embodiment, the fourth frame is implemented as a DMG perception measurement setting frame.

[0320] Illustratively, when the maximum duration field of a single-base PPDU is set in a DMG perception measurement setting frame, the maximum duration field of the single-base PPDU is carried in the optional sub-element field of the DMG perception measurement setting frame. The following describes the configuration of carrying the maximum duration field of the single-base PPDU in the optional sub-element field of the DMG perception measurement setting frame based on the differences in the selected optional sub-element fields.

[0321] Optionally, since the DMG perception measurement setting request frame and the DMG perception measurement setting response frame are both types of frames in the perception measurement setting stage, the DMG perception measurement setting frame is used to indicate the frames in the perception measurement setting stage, which include the DMG perception measurement setting request frame and the DMG perception measurement setting response frame in the perception measurement setting stage, thereby performing the following description process of character adjustment in the perception measurement setting stage.

[0322] In an optional embodiment, the optional sub-element field is a second collaborative single-base specific configuration sub-element.

[0323] Schematically, Figure 6 shows the format of a DMG Sensing Measurement Setup frame (DMG Sensing Measurement Setup Request frame or DMG Sensing Measurement Setup Response frame). This frame includes an Element ID field, a Length field, an Element ID Extension field, a Measurement Setup Control field, a Reporting Type field, an LCI field, a Peer Location field, and an Optional Sub-Element field. As shown in Table 3 above, the Optional Sub-Element field includes zero or more sub-elements, including the TX Beam List, RX Beam List, and DMG Sensing Scheduling.

[0324] Optionally, the perception measurement method provided in the embodiment of the present application is used to adjust the optional sub-elements under the optional sub-element field in the DMG perception measurement setting frame, and add a new sub-element field in the optional sub-element field.

[0325] Schematically, as shown in Figure 22, the optional sub-elements under the optional sub-element field in the DMG perception measurement setting frame shown in Figure 6 are adjusted, wherein the optional sub-element field in the DMG perception measurement setting frame is represented in bold; as shown in Table 10 below, a new coordinated monostatic specific configuration optional sub-element field (Coordinated Monostatic Specific Configuration) is added to the optional sub-element field, wherein the coordinated monostatic specific configuration sub-element field is represented in bold, and the coordinated monostatic specific configuration optional sub-element field is used to carry extended configuration information.

[0326] Table 10

[0327] Sub-element ID Sub-element Name Scalability 1 TX beam list Yes 2 RX beam list Yes 3 DMG-aware scheduling Yes 4 Cooperative single-base specific configuration Yes 5-255 Reserved No

[0328] In the collaborative single-base specific configuration optional sub-element field, the specific frame format is shown in Figure 23. The collaborative single-base specific configuration optional sub-element field includes a sub-element ID, a length, and a maximum duration field for the single-base PPDU. The value range of the sub-element ID is any integer between 4 and 255, and the value of the sub-element ID of 4 is only an illustrative example; the length indicates the number of bytes in the collaborative single-base specific configuration optional sub-element field excluding the sub-element ID and the length field; the maximum duration field of the single-base PPDU indicates the maximum duration of the single-base PPDU used by the perception responder STA in a DMG perception measurement setting. The unit of the maximum duration field of the single-base PPDU is the time unit adopted by the timing synchronization function timer (Timing Synchronization Function, TSF), that is, microseconds (us).

[0329] Among them, each STA in the same DMG perception measurement setting frame should configure the same maximum duration field of the single-base PPDU. Optionally, the above process of configuring the maximum duration field of the single-base PPDU is applicable to the perception measurement instance process occurring during the service period (SP).

[0330] In an embodiment of the present application, the format of the DMG perception measurement setting frame is adjusted, the optional sub-elements under the optional sub-element field are adjusted, a new sub-element field is added to the optional sub-element field, and the sub-element field includes the maximum duration field of the single-base PPDU, thereby more directly determining the maximum duration of the single-base PPDU based on the value of the maximum duration field of the single-base PPDU.

[0331] In an optional embodiment, the optional sub-element field is a perception measurement scheduling sub-element.

[0332] Schematically, Figure 6 shows the format of a DMG Sensing Measurement Setup frame (DMG Sensing Measurement Setup Request frame or DMG Sensing Measurement Setup Response frame). This frame includes an Element ID field, a Length field, an Element ID Extension field, a Measurement Setup Control field, a Reporting Type field, an LCI field, a Peer Location field, and an Optional Sub-Element field. As shown in Table 3 above, the Optional Sub-Element field includes zero or more sub-elements, including the TX Beam List, RX Beam List, and DMG Sensing Scheduling.

[0333] Optionally, the perception measurement method provided in an embodiment of the present application is used to adjust the optional sub-elements under the optional sub-element field in the DMG perception measurement setting frame. In an exemplary embodiment, the perception measurement scheduling sub-element (DMG Sensing Scheduling) in the optional sub-element field is adjusted. The perception measurement scheduling sub-element is used for configuration information related to the perception measurement instance and the perception measurement burst.

[0334] Schematically, as shown in Figure 24, the optional sub-elements under the optional sub-element field in the DMG perception measurement setting frame shown in Figure 6 are adjusted, wherein the optional sub-element field in the DMG perception measurement setting frame is represented in bold; as shown in Table 11 below, in the optional sub-element field, the perception measurement scheduling sub-element is adjusted, and a new field is added to the perception measurement scheduling sub-element, wherein the perception measurement scheduling sub-element is represented in bold.

[0335] Table 11

[0336] Sub-element ID Sub-element Name Scalability 1 TX beam list Yes 2 RX beam list Yes 3 DMG-aware scheduling Yes 4-255 Reserved No

[0337] The perception measurement scheduling sub-element also carries at least one of the following fields: the start time of the perception measurement burst; the time interval between adjacent perception measurement bursts; the time interval between adjacent perception measurement instances in a perception measurement burst; the number of receive beams used in a perception measurement instance; the number of repeated transmissions required in a perception measurement instance; and the number of repetitions of the perception measurement burst.

[0338] Schematically, as shown in FIG25 , the frame format of the perception measurement scheduling sub-element is shown, that is, the fields carried in the perception measurement scheduling sub-element.

[0339] The perception measurement scheduling sub-element includes a sub-element ID field, a length field, a perception measurement burst start time field (Start of Burst), an interval field between adjacent perception measurement bursts (Inter-burst interval), an interval field between adjacent perception measurement instances in a perception measurement burst (Intra-burst interval), and a number of receive beams used in a perception measurement instance field (Number TXBeams Per Instance); a number of repeated transmissions required in a perception measurement instance field (Repeat Per Instance), a number of repetitions of the perception measurement burst field (Number Bursts), and a maximum duration field for a single-base PPDU.

[0340] The value of the sub-element ID field is any integer between 4 and 255. The value 4 is only an example.

[0341] The length field indicates the number of bytes in the perception measurement scheduling sub-element excluding the sub-element ID field and the length field;

[0342] The start time field of the perception measurement burst is used to indicate the start time of a burst, and the time is in the unit of TSF time - us;

[0343] The time interval between adjacent sensing measurement bursts field is used to indicate the time interval between adjacent bursts, and the unit is TSF time unit - us;

[0344] The time interval between adjacent sensing measurement instances in a sensing measurement burst field is used to indicate the time interval between adjacent instances in a burst, and the unit is TSF time unit - us;

[0345] The field "Number of receive beams used in a perception measurement instance" is used to indicate the number of TX beams to be used in an instance.

[0346] The number of retransmissions required in a perception measurement instance field is used to indicate the number of retransmissions required in an instance;

[0347] The Perception Measurement Burst Repetition Count field is used to indicate the number of times the Burst is repeated. A value of 0 indicates that the Burst is repeated until the perception measurement setting is terminated.

[0348] Among them, the maximum duration field of the monostatic PPDU is used to indicate the maximum duration of the monostatic PPDU used by the perception responder STA in a DMG perception measurement setting, and the unit of the maximum duration field of the monostatic PPDU is the unit of TSF time. Each STA in the same DMG perception measurement setting should be configured with the same maximum duration of the monostatic PPDU (Maximum Duration of Monostatic PPDU). Optionally, the above process of configuring the maximum duration field of the monostatic PPDU is applicable to the case where the perception measurement instance process occurs during the service period (SP).

[0349] In an embodiment of the present application, when adjusting the format of the DMG perception measurement setting frame, the existing perception measurement scheduling sub-element is adjusted, and a maximum duration field of the single-base PPDU is added to the perception measurement scheduling sub-element, thereby more directly determining the maximum duration of the single-base PPDU based on the value of the maximum duration field of the single-base PPDU.

[0350] In schematic form, based on the difference in information carried by the first field, when the perception initiator sends a frame carrying the first field to the perception responder, different information contents can be conveyed to the perception responder. Different types of first fields can achieve the purpose of conveying different information to the perception responder more quickly and directly.

[0351] The aforementioned proprietary fields, such as the Sensing Type field, Site Identification field, Report Polling field, and Single-Based PPDU Maximum Duration field, can all be implemented as a first field. The frame sent by the Sensing Initiator to the Sensing Responder includes at least one of the aforementioned first fields. Depending on the first field, the Sensing Initiator can convey at least one piece of information to the Sensing Responder. Furthermore, the positions of proprietary fields, such as the Measurement Type field, Site Identification field, Report Polling field, and Single-Based PPDU Maximum Duration field, can be arbitrarily combined.

[0352] It is worth noting that the above-mentioned first frame, second frame, third frame and fourth frame do not represent the order of frames. When a frame carries the above-mentioned multiple fields, any two frames or at least two frames among the first frame, second frame, third frame and fourth frame can be implemented as the same frame. For example: when a frame carries the perception type field and the report polling field, then the frame belongs to the first frame and also to the second frame, that is, the first frame and the second frame belong to the same frame; or, when a frame carries the perception type field and the maximum duration field of the single-base PPDU, then the frame belongs to the first frame and also to the third frame, that is, the first frame and the third frame belong to the same frame. The above is only an illustrative example and is not limited to this in the embodiments of the present application.

[0353] That is, it should be noted that the above embodiments can be freely combined or split into new embodiments, and this application does not limit this.

[0354] FIG26 is a block diagram of a perception measurement device 2600 provided by an exemplary embodiment of the present application. As shown in FIG26 , the device is located in a perception measurement device and includes:

[0355] The sending module 2601 is configured to send a frame carrying a first field;

[0356] The first field is a dedicated field of the sequential collaboration unit base or the parallel collaboration unit base, and / or the first field has a dedicated meaning in the sequential collaboration unit base or the parallel collaboration unit base.

[0357] In an optional embodiment, the sending module 2601 is further configured to send a first frame carrying a perception type field, where the perception type field is configured to indicate that the perception type is the sequential collaborative single-radix or the parallel collaborative single-radix.

[0360] Millimeter wave DMG perception measurement setting response frame;

[0361] Millimeter wave DMG perception request frame.

[0362] In an optional embodiment, the sending module 2601 is further configured to send a second frame carrying a site identification field, where the site identification field is used to indicate the order in which the sites participate in the sequential collaborative single-base.

[0363] The second frame is a DMG perception request frame;

[0364] In an optional embodiment, when the perception type field in the DMG perception request frame indicates the sequential collaborative single base, the site identification field is used to indicate the order in which the site participates in the sequential collaborative single base;

[0365] or,

[0366] In the case where the perception type field in the DMG perception request frame indicates a collaborative single base, the value of the site identification field belongs to the first range for indicating the sequential collaborative single base, and the value of the site identification field is also used to indicate the order in which the sites participate in the sequential collaborative single base.

[0367] In an optional embodiment, when the perception type field in the DMG perception request frame indicates the collaborative single base, the value of the site identification field belongs to the second range to indicate the parallel collaborative single base.

[0368] In an optional embodiment, the sending module 2601 is further configured to send a third frame carrying a reporting polling field, where the reporting polling field is used to indicate whether reporting of the perception measurement result requires polling.
