[0041] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.
[0042] This disclosure provides a communication method, apparatus, electronic device, and storage medium for providing a format of NDPA frames during WLAN sensing.
[0043] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.
[0044] like Figure 1 As shown in the illustration, this disclosure provides a communication method. Optionally, the method can be applied to a network device, which can be a sensing initiator. The method may include the following steps:
[0045] Step 101, determine the target wireless frame; wherein, the target wireless frame includes a first identifier bit, the first identifier bit indicating the wireless local area network (WLAN) sensing measurement process corresponding to the target wireless frame;
[0046] As a first example, see Figures 2 to 4 First, the architecture and process of the WLAN sensing measurement method provided in this disclosure are introduced.
[0047] Figure 2 The diagram illustrates an architecture for WLAN Sensing; in this process, a sensing initiator (or initiator terminal) initiates WLAN Sensing (e.g., initiates a WLAN sensing session), and multiple sensing responders (SensingResponder, or sensing receiver) or responding terminals may respond to it, such as... Figure 2 The response terminals 1, 2, and 3 are shown in the diagram. When the sensing initiator initiates WLAN Sensing, multiple associated or unassociated WLAN Sensing response terminals can respond.
[0048] See Figure 3 The sensing initiator and the sensing responder communicate through a communication connection, as shown in communication connection S1; the sensing responders communicate with each other through communication connection S2.
[0049] In this context, each sensing initiator can be a client; each sensing responder (in this example, sensing responder 1 to sensing responder 3) can be a station device (STA) or an access point device (AP). Furthermore, STAs and APs can assume multiple roles in the WLAN sensing process; for example, an STA can act as a sensing initiator, which may be a sensing transmitter, a sensing receiver, or both, or neither. Similarly, a sensing responder can also be a sensing transmitter, a sensing receiver, or both.
[0050] As another architecture, such as Figure 4 As shown, both the sensing initiator and the sensing response end can be clients, and they can communicate by connecting to the same access point (AP) device. Figure 4 In this context, Client1 is the sensing initiator, and Client2 is the sensing response provider.
[0051] Typically, during WLAN sensing, such as in downlink sensing measurement (DL Sensing), the initiating end determines the target radio frame and carries a first identifier bit in the target radio frame. The first identifier bit indicates the WLAN sensing measurement process corresponding to the target radio frame. Optionally, the first identifier bit may include a measurement setup ID and / or a sensing measurement event ID. Each measurement setup ID may correspond to one or more measurement instance IDs. The first identifier bit is carried in the target radio frame to indicate the WLAN sensing measurement process corresponding to the target radio frame at the sensing response end. For example, the measurement setup ID and / or measurement instance ID may be carried in the probe dialog token field of the target radio frame.
[0052] Step 102: Send the target radio frame to the sensing response terminal, instructing the sensing response terminal to receive the empty data packet NDP.
[0053] Optionally, during the DL Sensing Sounding process in a WLAN Sensing scenario, the target radio frame type can be a WLAN Sensing NDPA frame. An NDPA (Null Data Packet Announcement) frame is used to instruct the responding end to receive a null data packet (Null Data Packet, NDP). For example, during DL Sensing Sounding, after sending an NDPA frame, the sensing initiator will send an NDP; therefore, the sensing responding end needs to receive the NDP frame. It is understood that during the WLAN Sensing process, multiple sensing responding ends may participate in the Measurement Instance.
[0054] In this embodiment of the disclosure, a target wireless frame is determined; wherein, the target wireless frame includes a first identifier bit, the first identifier bit indicating the WLAN sensing measurement process corresponding to the target wireless frame; the target wireless frame is sent to the sensing response end, instructing the sensing response end to receive empty data packets; this embodiment of the disclosure provides an NDPA frame format for implementing WLAN sensing measurement.
[0055] In an optional embodiment, the first identifier bit includes: a measurement setup ID included in the WLAN sensing measurement process, and / or a measurement instance ID corresponding to the measurement setup ID; the measurement setup ID is used to identify the sensing measurement process; the WLAN sensing measurement process may include one or more measurement instances, that is, each measurement setup ID can correspond to one or more measurement instance IDs; the first identifier bit may carry the measurement setup ID, or it may directly carry the measurement instance ID (the measurement instance ID can uniquely identify a sensing measurement event), or it may include both.
[0056] In an optional embodiment, the target radio frame includes a sounding dialogtoken field;
[0057] The first identifier is carried in the probe token field; optionally, the aforementioned Measurement Setup ID and the corresponding Measurement Instance ID can be carried in the probe token number subfield. The probe token field can consist of two parts: Measurement Setup ID and Measurement Instance ID; wherein, the same Measurement Setup ID may contain multiple Measurement Instance IDs.
[0058] In an optional embodiment, the target radio frame includes a STA info field; the NDPA frame contains at least one STA info field.
[0059] The STA info field includes an Association Identifier (AID) or a User Identifier (UID) bit. The AID or UID bit indicates the responding end participating in the WLAN sensing measurement process; that is, the AID or UID bit indicates the responding end of the sensing detection. AID represents the Association Identifier, and UID represents the User Identifier. Optionally, for responding ends that have not established an association (association being a communication connection) with the initiating end, their AID can be assigned by the initiating end during the WLAN sensing measurement setup process.
[0060] In an optional embodiment, the STA info field further includes sensing measurement parameter information corresponding to the AID or UID identifier bit. This sensing measurement parameter information may include partial bandwidth (BW) information, resource unit (RU) information, and / or number of spatial streams (NSS) parameter information. The RU information is determined based on the transmission bandwidth of the NDPA frame. For example, when the transmission bandwidth is 20MHz, the RU information is identified as 26-tone feedback (802.11ax version) or 242-tone feedback (802.11be version). If there is a mixture of 802.11ax and 802.11be, it is 26-tone feedback. Optionally, the NSS number identifies the NSS parameter information for transmitting downlink measurement NDPA frames.
[0061] In an optional embodiment, the STA info field also includes parameter information corresponding to the NDP sent by the responding end; during the WLAN Sensing process, after receiving the NDPA frame, the responding end will also send back an NDP frame (which is a different NDP from the NDP received by the sensing responding end in step 102) to the sensing initiating end; therefore, the STA info field also includes parameter information of the NDP frame sent by the responding end, such as NSS information, bandwidth information, etc.
[0062] In an optional embodiment, the target wireless frame further includes a second identifier bit, which indicates that the type of the target wireless frame is a WLAN Sensing Null Data Packet Announcement (NDPA) frame; during the DL Sensing Sounding process in a WLAN Sensing scenario, the NDPA frame is used to indicate that the responding end receives a null data packet (NDP).
[0063] In an optional embodiment, the second identifier is carried in: the control field of the target radio frame, the subtype subtype of the control field, or the sounding dialog token field.
[0064] As an example, taking the control domain as an example, the effective type domain and subtype subdomain combinations of the target radio frame are shown in Table 1 below:
[0065] Table 1:
[0066]
[0067] When the Type value is 01, it is the control field, and a second flag bit can be carried in the control field; for example, the second flag bit can be carried in the sub-type sub-field corresponding to the bits 0000–0001.
[0068] In addition, a second identifier bit can be used in the sounding dialog token field.

[0081] Optionally, in this embodiment of the disclosure, the second identifier bit is carried in: the control domain of the target wireless frame, a sub-type sub-domain of the control domain, or a probe dialogue token domain.
[0082] See Figure 5 This disclosure also provides a communication method applied to a sensing response end, the method comprising:
[0083] Step 501: Receive the target wireless frame and obtain the first identifier bit carried in the target wireless frame. The first identifier bit indicates the wireless local area network (WLAN) sensing measurement process corresponding to the target wireless frame.
[0084] As a first example, see Figures 2 to 4 First, the architecture and process of WLAN Sensing applied to the communication method provided in this embodiment will be introduced. For details, please refer to the foregoing embodiments, which will not be repeated here.
[0085] During WLAN sensing, such as in downlink sensing measurement (DL Sensing), the initiating end determines a target radio frame and carries a first identifier bit in the target radio frame. The first identifier bit indicates the WLAN sensing measurement process corresponding to the target radio frame. Optionally, the first identifier bit may include a measurement setup ID and / or a measurement instance ID. Each measurement setup ID may correspond to one or more measurement instance IDs. The first identifier bit is carried in the target radio frame to indicate the WLAN sensing measurement process corresponding to the target radio frame at the sensing response end. For example, the measurement setup ID and / or measurement instance ID may be carried in the probe dialog token field of the target radio frame.
[0086] Step 502: Receive empty data packet NDP according to the first identifier bit.
[0087] Optionally, during the DL Sensing Sounding process in a WLAN Sensing scenario, the target radio frame type can be a WLAN Sensing NDPA frame. An NDPA (Null Data Packet Announcement) frame is used to instruct the responding end to receive a null data packet (Null Data Packet, NDP). For example, during DL Sensing Sounding, after sending an NDPA frame, the sensing initiator will send an NDP; therefore, the sensing responding end needs to receive the NDP frame. It is understood that during the WLAN Sensing process, multiple sensing responding ends may participate in the Measurement Instance.
[0088] In this embodiment of the present disclosure, the sensing response end receives a target wireless frame, obtains a first identifier bit carried in the target wireless frame, the first identifier bit indicating the WLAN sensing measurement process corresponding to the target wireless frame; and receives an empty data packet (NDP) based on the first identifier bit. This embodiment of the present disclosure provides an NDPA frame format for implementing WLAN sensing measurement.

[0090] In an optional embodiment, the target radio frame includes a sounding dialog token number.
[0091] The first identifier is carried in the probe token field; optionally, the aforementioned Measurement Setup ID and the corresponding Measurement Instance ID can be carried in the probe token number subfield. The probe token field can consist of two parts: Measurement Setup ID and Measurement Instance ID; wherein, the same Measurement Setup ID may contain multiple Measurement Instance IDs.
[0092] In an optional embodiment, the target radio frame includes a STA info field; the NDPA frame contains at least one STA info field.
[0093] The STA info field includes an Association Identifier (AID) or a User Identifier (UID) bit. The AID or UID bit indicates the responding end participating in the WLAN sensing measurement process; that is, the AID or UID bit indicates the responding end of the sensing detection. AID represents the Association Identifier, and UID represents the User Identifier. Optionally, for responding ends that have not established an association (association being a communication connection) with the initiating end, their AID can be assigned by the initiating end during the WLAN sensing measurement setup process.
[0094] In an optional embodiment, the STA info field further includes sensing measurement parameter information corresponding to the AID or UID identifier bit. This sensing measurement parameter information may include partial bandwidth (BW) information, resource unit (RU) information, and / or number of spatial streams (NSS) parameter information. The RU information is determined based on the transmission bandwidth of the NDPA frame. For example, when the transmission bandwidth is 20MHz, the RU information is identified as either 26-tone feedback (802.11ax version) or 242-tone feedback (802.11ax version). If there is a mixture of 802.11ax and 802.11ax, then it is 26-tone feedback. Optionally, the NSS number identifies the NSS parameter information for transmitting downlink measurement NDPA frames.
[0095] In an optional embodiment, the STA info field also includes parameter information corresponding to the NDP sent by the responding end; during the WLAN Sensing process, after receiving the NDPA frame, the responding end will send back the NDP frame to the sensing initiator; therefore, the STA info field also includes parameter information of the NDP frame sent by the responding end, such as NSS information, bandwidth information, etc.
[0096] In an optional embodiment, the target wireless frame further includes a second identifier bit, which indicates that the type of the target wireless frame is a WLAN Sensing Null Data Packet Announcement (NDPA) frame; during the DL Sensing Sounding process in a WLAN Sensing scenario, the NDPA frame is used to indicate that the responding end receives a null data packet (NDP).
