[0017] The following description, with reference to the accompanying drawings, is provided to aid in a comprehensive understanding of the various embodiments of this disclosure as defined by the appended claims and their equivalents. The various embodiments of this disclosure include a variety of specific details, but these details are to be considered exemplary only. Furthermore, for clarity and brevity, descriptions of well-known techniques, functions, and constructions may be omitted.

[0018] The terms and words used in this disclosure are not limited to their literal meanings, but are used solely by the inventors to ensure a clear and consistent understanding of the disclosure. Therefore, the descriptions of various embodiments of the disclosure provided are for illustrative purposes only and not for limiting purposes.

[0019] It should be understood that, unless the context clearly indicates otherwise, the singular forms “a,” “an,” “the,” and “the” used herein may also include the plural forms. It should be further understood that the word “comprising” as used in this disclosure means the presence of the described features, integers, steps, operations, elements, and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0020] It will be understood that although the terms “first,” “second,” etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Therefore, without departing from the teachings of the example embodiments, the first element discussed below may be referred to as the second element.

[0021] It should be understood that when an element is referred to as “connected” or “coupled” to another element, it can be directly connected or coupled to the other element, or there may be an intermediate element. Furthermore, the use of “connected” or “coupled” herein can include wireless connections or wireless couplings. The terms “and / or” or the expression “at least one of…” as used herein include any and all combinations of one or more of the associated listed items.

[0022] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains.

[0023] Figure 1 This is an example of how WLAN awareness is demonstrated.

[0024] The process of WLAN sensing can be as follows: an initiator initiates WLAN sensing (e.g., initiates a WLAN sensing session), and there may be multiple responders responding to it. Specific possible methods include... Figure 1 As shown in (a), (b) and (c) in the figure.

[0025] Reference Figure 1 In (a) of this clause, when a WLAN sensing initiator (e.g., a client) initiates WLAN sensing, multiple associated or unassociated WLAN sensing responders (e.g., three access points (APs)) can respond. Here, "associated" can refer to an association connection established between the initiator and the responder for communication, while "unassociated" can refer to an association connection not established between the initiator and the responder for communication.

[0026] As an example, a client may include, but is not limited to: cellular phones, smartphones, wearable devices, computers, personal digital assistants (PDAs), personal communication system (PCS) devices, personal information managers (PIMs), personal navigation devices (PNDs), global positioning systems, multimedia devices, Internet of Things (IoT) devices, etc.

[0027] An access point (AP) can be a wireless switch for a wireless network or an access device for a wireless network. An AP may include software applications and / or circuitry to enable other types of nodes in the wireless network to communicate with the outside and inside of the wireless network. As an example, an AP may be a terminal device or network device equipped with a Wi-Fi (Wireless Fidelity) chip.

[0028] Figure 1 (b) and Figure 1 Similar to (a) in, but in Figure 1 In (b) of the above, the various responders (APs) can communicate with each other.

[0029] Reference Figure 1 In (c), both the WLAN sensing initiator and the WLAN sensing responder can be clients, and they can communicate by connecting to the same AP.

[0030] Although Figure 1 As shown in (a), (b), and (c) above, the client acts as the initiator and the AP as the responder; however, this disclosure is not limited thereto. For example, the AP can act as the initiator and the client as the responder. Furthermore, the number of initiators and responders is not limited to [specific details needed]. Figure 1 As shown in (a), (b) and (c) in the figure.

[0031] In addition, although Figure 1 The disclosure only shows APs participating in WLAN sensing, but it is not limited to this. For example, PCPs (PBSS (personal basic service set) control points) can also participate in WLAN sensing.

[0032] For example, in the 60GHz spectrum, the AP / PCP can transmit sensing signaling, such as directional beacon frames. The format (or content) of these directional beacon frames can be the same as ordinary (or regular) beacon frames. Furthermore, in WLAN sensing, passive sensing may exist; that is, the receiver only receives the sensing signaling sent by the AP / PCP without sending its own sensing signaling. In other words, the AP / PCP can act as the initiator (hereinafter also referred to as the "sender"), and the receiver can act as the responder. In this paper, the receiver can be referred to as a passive station (STA), which can be similar to a reference station. Figure 1 The client described.

[0033] For example, directional beacon frames sent by the AP / PCP can serve as sensing signaling. The receiver, used for passive sensing, can utilize these frames to perform WLAN sensing measurements and feed back the results to the AP / PCP. However, current research lacks robust mechanisms for passive sensing measurements. For instance, the receiver needs information such as the period and direction of the sensing signaling used for passive sensing, but current research lacks corresponding support mechanisms, which need to be enhanced.

[0034] In view of this, a communication method and a communication apparatus according to embodiments of the present disclosure are provided.

[0035] Figure 2 This is a flowchart illustrating a communication method according to an example embodiment. Figure 2 The communication method shown can be applied to WLAN-aware transmitting devices, such as APs or PCPs as described above.

[0036] Reference Figure 2 In step 210, a request frame is received. Specifically, the sending device receives the request frame from the receiving device. For example, the request frame may include information about a beacon frame requested for passive sensing measurements. For example, the receiving device may be a passive site, examples of which may include, but are not limited to: cellular phones, smartphones, wearable devices, computers, personal digital assistants (PDAs), personal communication system (PCS) devices, personal information managers (PIMs), personal navigation devices (PNDs), global positioning systems, multimedia devices, Internet of Things (IoT) devices, etc. Furthermore, although beacon frames for passive sensing measurements are described herein, this disclosure is not limited thereto, and other sensing signaling that can be used for passive sensing measurements is also possible.

[0037] According to embodiments of this disclosure, a request frame may include information about a beacon frame that the receiving device requests to know. In other words, through a request frame sent by the receiving device, the sending device can learn about the beacon frame information requested by the receiving device. For example, the request frame may include the transmission period and transmission direction of the beacon frame. In this case, the transmission period and transmission direction of the beacon frame included in the request frame may be undetermined fields, used only to make the sending device aware of the information requested by the receiving device. Furthermore, as a non-limiting embodiment, the transmission direction information includes TRN (training sequence field) information, which is used to indicate the transmission direction of the beacon frame.

[0038] According to another embodiment of this disclosure, the request frame may further include timestamp information for time synchronization. For example, if the passive station acting as the receiving device has not established an initial association with the AP / PCP, the request frame may further include timestamp information for the passive STA to synchronize time with the AP / PCP.

[0039] In step 220, a response frame is transmitted. Specifically, the transmitting device transmits a response frame to the receiving device. For example, the response frame may include information about a beacon frame used for passive sensing measurements. According to embodiments of this disclosure, the beacon frame information may include the transmission period and transmission direction of the beacon frame. In this case, the transmission period and transmission direction of the beacon frame included in the response frame may be specific transmission periods and transmission directions. For example, the transmission period may refer to the period during which the beacon frame will be transmitted, and the transmission direction may refer to information such as the azimuth, elevation direction (or radiation pattern), and / or power of the antenna when the transmitting device transmits the beacon frame.

[0040] According to embodiments of this disclosure, the information in the beacon frame may further include the initial transmission direction information of the beacon frame. For example, the initial transmission direction information of the beacon frame may refer to the initial order in the transmission sequence of the beacon frames. Specifically, the initial transmission direction information may define the direction in which the first beacon frame is transmitted, so that from this starting direction, beacon frames are transmitted sequentially in each direction according to the transmission cycle for passive sensing.

[0041] According to embodiments of this disclosure, the response frame may further include timestamp information for time synchronization. This timestamp information can be used for time synchronization between the AP / PCP and the passive STA, ensuring accurate transmission and reception of beacon frames.

[0042] In steps 210 and 220, the beacon frame used for passive sensing measurement can be a lightweight beacon frame or a regular beacon frame used only for passive sensing measurement. For example, since a lightweight beacon frame is used only for passive sensing measurement, that is, it only contains the necessary information required for passive sensing measurement, the information contained in the lightweight beacon frame is less, which helps to reduce the power consumption of transmitting the lightweight beacon frame and improve the efficiency of sensing measurement. In addition, when the beacon frame is a lightweight beacon frame, the response frame may also include the transmission time interval of the beacon frame. By carrying the transmission time interval of the lightweight beacon frame in the response frame, the receiving device can receive the lightweight beacon frame at a more accurate time for passive sensing measurement. In the embodiments of this disclosure, a regular beacon frame can also be used as sensing signaling for passive sensing measurement. In this case, the response frame may include the transmission period and transmission direction of the regular beacon frame as described in step 220, or it may also include the start transmission direction information of the regular beacon frame, etc.

[0043] Although Figure 2 A communication method performed by a sending device according to an embodiment of the present disclosure is shown; however, the embodiments of the present disclosure are not limited thereto.

[0044] In another embodiment of this disclosure, a communication method performed by a sending device may include: the sending device broadcasting a regular beacon frame to a receiving device. The regular beacon frame may include, for example, but not limited to, identification information indicating that the beacon frame supports passive sensing measurement signaling.

[0045] In another embodiment of this disclosure, a communication method performed by a sending device may include sending a response frame to a receiving device. The response frame may include information about a beacon frame used for passive sensing measurements. For example, the beacon frame information may include the beacon frame's transmission period and transmission direction. Alternatively, the beacon frame information may also include the beacon frame's initial transmission direction information. That is, the response frame may include the beacon frame's transmission period and transmission direction, or optionally, it may also include the beacon frame's initial transmission direction information. Furthermore, optionally, the response frame may also include timestamp information for time synchronization. Additionally, if the beacon frame used for passive sensing measurements is a lightweight beacon frame, the request frame may also include the lightweight beacon frame's transmission time interval.

[0046] In another embodiment of this disclosure, a communication method performed by a sending device may include sending a lightweight beacon frame to a receiving device, which is used solely for passive sensing measurements. The lightweight beacon frame contains only the necessary information required for the passive sensing measurements. Furthermore, the sending direction and sending period, or (optionally) the sending time interval of the lightweight beacon frame, may be communicated to the receiving device in advance by the sending device.

[0047] In another embodiment of this disclosure, a communication method performed by a sending device may include sending a conventional beacon frame for passive sensing measurement to a receiving device. This conventional beacon frame may include, in addition to the information required for passive sensing measurement, various other information, such as network information or channel information for managing data transmission. Furthermore, the sending direction and transmission period of the conventional beacon frame may be pre-notified to the receiving device by the sending device. According to the communication method of the embodiments of this disclosure, the mechanism of passive sensing measurement can be improved by defining information such as the transmission period and transmission direction of the beacon frame for passive sensing measurement between the sending device and the receiving device through request frames and response frames.

[0048] Figure 3 This is a flowchart illustrating the interaction between a sending device and a receiving device according to an example embodiment. The sending device can be an AP / PCP, and the receiving device can be a passive STA.

[0049] Reference Figure 3 In step S310, the AP / PCP can send a regular beacon frame to the passive STA. Specifically, before receiving the request frame, the sending device can broadcast a regular beacon frame, which may include identification information indicating that the beacon frame supports passive sensing measurement signaling. For example, the AP / PCP can carry an identification bit in the regular beacon frame; as a non-limiting example, it may indicate that the beacon frame supports passive sensing measurement signaling in the DMG (directional multi-Gigabit) capability information element of the regular beacon frame.

[0050] In step S320, if a passive STA receives a broadcast regular beacon frame, it can send a request frame to the AP / PCP. This request frame may include the transmission period and corresponding transmission direction of a directional beacon frame used for passive sensing. The transmission direction may include TRN information to indicate the transmission direction of the directional beacon frame. Additionally, for STAs that have not established an initial association with the AP / PCP, timestamp information may also be included, which is used for time synchronization. The directional beacon frame described in this embodiment can refer to sensing signaling used for passive sensing measurements, such as the lightweight beacon frame described above, or a regular beacon frame with a period and direction. However, this disclosure is not limited to this; the request frame may also include the starting transmission direction information of the directional beacon frame, etc.

[0051] In step S330, the AP / PCP may reply with a response frame to the passive STA. This response frame may contain information such as the direction in which the AP / PCP sends the directional beacon frames and their corresponding periodicity. Furthermore, the response frame may also contain a timestamp field for time synchronization between the AP and the STA. Additionally, the response frame may also contain start information for directional beacon frame transmission (such as the start transmission direction information described in step 220), which indicates the order in which the directional beacon frames are transmitted.

[0052] In step S340, the AP / PCP can send directional beacon frames based on the transmission period, transmission direction, or initial transmission direction information defined by the request and response frames, and the passive STA can periodically receive the sent directional beacon frames. The passive STA can use the received directional beacon frames to perform WLNA sensing measurements, and in step S350, it can feed back the sensing measurement results to the AP / PCP, such as, but not limited to, channel state information (CSI). As a non-limiting example, the passive STA can feed back the sensing measurement results after receiving multiple directional beacon frames (delayed feedback), or it can feed back the sensing measurement results each time a directional beacon frame is received (timely feedback).

[0053] In addition, although Figure 3 The embodiment described uses directional beacon frames as sensing signaling, but this disclosure is not limited thereto. In step S310, it can be defined that regular beacon frames can support passive sensing measurement. In steps S320 and S330, the transmission period, transmission direction, or initial transmission direction information of regular beacon frames can be defined. In steps S340 and S350, passive sensing measurement can be performed using regular beacon frames.

[0054] Figure 4 This is a flowchart illustrating another communication method according to an example embodiment. Figure 4 The communication method shown can be applied to the receiving device, for example, Figure 3 The passive STA shown.

[0055] Reference Figure 4 In step 410, the receiving device may send a request frame to the sending device. This request frame may include information about beacon frames used for passive sensing measurements, which it requests to be obtained. For example, the beacon frame information may include the beacon frame's transmission period and direction. Furthermore, the request frame may also include timestamp information for time synchronization. Step 410 can be similar to step S320 described above; for simplicity, repeated descriptions are omitted here.

[0056] In step 420, the receiving device may receive a response frame from the sending device, wherein the response frame may include information about the beacon frame. For example, the response frame may also include timestamp information for time synchronization. For example, the beacon frame information may include the beacon frame's transmission period and transmission direction. For example, the beacon frame information may also include the beacon frame's initial transmission direction information.

[0057] According to embodiments of this disclosure, the beacon frame may be a lightweight beacon frame used only for passive sensing measurements or a conventional beacon frame.

[0058] According to embodiments of this disclosure, when the beacon frame is a lightweight beacon frame, the response frame further includes: the beacon frame's time interval.

[0059] Step 420 can be similar to the operation of step S330 above. For the sake of brevity, repeated descriptions are omitted here.

[0060] Will understand, Figure 4 The communication methods shown are merely exemplary, and this disclosure is not limited thereto. For example, Figure 4 The communication method shown may also include Figure 3 The operations performed by the passive STA.

[0061] For example, Figure 4 The communication method shown may further include: before sending a request frame, the receiving device receives a regular beacon frame from the sending device, wherein the regular beacon frame may include identification information for identifying that the beacon frame supports passive sensing measurement signaling. The regular beacon frame and the identification information it includes may be similar to the embodiment described with reference to step S310, and for the sake of brevity, repeated descriptions are omitted here.

[0062] Although Figure 4 A communication method performed by a receiving device according to an embodiment of the present disclosure is shown; however, the embodiments of the present disclosure are not limited thereto.

[0063] In another embodiment of this disclosure, a communication method performed by a receiving device may include sending a request frame to a sending device, wherein the request frame may include information about a beacon frame requested for passive sensing measurements. For example, the beacon frame information may include the beacon frame's transmission period and transmission direction. Alternatively, the beacon frame information may also include the beacon frame's initial transmission direction information. In other words, the request frame may include the requested beacon frame's transmission period and transmission direction, or optionally, it may also include the requested beacon frame's initial transmission direction information. Furthermore, optionally, the request frame may also include timestamp information for time synchronization; for example, if the receiving device (e.g., a passive STA) has not established an initial association with the sending device (e.g., an AP / PCP), the request frame may also include timestamp information for time synchronization between the passive STA and the AP / PCP.
