[0047] 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.
[0048] This disclosure provides a WLAN sensing measurement method and apparatus, electronic device and storage medium, for providing a way to indicate whether the same message frame is sent multiple times.
[0049] 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.
[0050] like Figure 1 As shown in the illustration, this disclosure provides a WLAN sensing measurement method. Optionally, the method can be applied to an electronic device, which can be a network device, such as a sensing initiator. Specifically, the method may include the following steps:
[0051] Step 101: Determine the first radio frame; wherein the first radio frame carries a first identifier bit, the first identifier bit indicating whether the first radio frame should be transmitted again within the target transmission opportunity TXOP or the target sensing time window.
[0052] As a first example, see Figures 2 to 4 First, the architecture and process of WLAN Sensing applied in the WLAN sensing measurement method provided in the embodiments of this disclosure will be introduced.
[0053] Figure 2 The diagram illustrates an architecture for a WLAN sensing process. The sensing initiator (or initiator terminal) initiates WLAN sensing (e.g., initiates a WLAN sensing session). Multiple sensing responders (or sensing receivers) may respond to this process, 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.
[0054] 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.
[0055] 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 (STA) or an access point (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.
[0056] 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.
[0057] As a second example, see Figure 5 This illustrates multiple sensing measurement events (Measurement Instances) of a TB-based sensing measurement process; in Examples 1 to 5, the sensing measurement process includes polling, probing, and reporting (LTF sec.update) processes; in each example, probing may include only NDPAsounding or TF Sounding; or it may include both.
[0058] In TB-based scenarios, there may be situations where the same message frame needs to be sent multiple times, i.e., the first wireless frame in this embodiment. The first wireless frame may be, for example, a polling frame or a trigger frame (TF). The polling frame is used to detect site devices participating in sensing measurements, and the trigger frame is used to allocate uplink sensing measurement resources to site devices participating in uplink sensing measurements. For example, the first wireless frame also includes a second identifier bit, wherein when the second identifier bit is set to a first identifier value, the first wireless frame is identified as a polling frame; when the second identifier bit is set to a second identifier value, the first wireless frame is identified as an (uplink) sensing trigger frame. It is understood that in this embodiment, the target transmission opportunity TXOP or the target sensing time window corresponds to the same time period as the time period in step 102 when the first wireless frame is sent, which is the same WLAN SensingMeasurement Setup ID.
[0059] As a third example, see Figure 6 Taking the first wireless frame as the polling frame as an example, in a WLAN sensing measurement process corresponding to the same sensing measurement establishment identifier, there are multiple measurement events, such as... Figure 6The sensing measurement events 1 and 2 shown in the diagram require multiple polling frames to indicate that they contain multiple sensing measurement events. For example, the sensing initiator performs step 1 for sensing measurement event 1, sending a first polling frame; step 2, sending a first trigger frame; and step 3 for sensing measurement event 2, sending a second polling frame; and step 4, sending a second trigger frame. Or, in a measurement event, since the sensing measurement bandwidth cannot meet the needs of all participating responders, multiple TF frames may be sent. For example, for sensing measurement event 2, the initiator performs step 3, sending a second polling frame; step 4, sending a second trigger frame; then, step 5, sending a third polling frame; and step 6, sending a third trigger frame. Therefore, in this embodiment, a first identifier bit is carried in the first radio frame. The first identifier bit indicates whether the first radio frame will be sent again within the target transmission opportunity (TXOP) or target sensing time window, to indicate whether the sensing initiator will send the first radio frame again later. For example, when the first flag is set to a first parameter value, such as "1", the first radio frame will be transmitted again within the target TXOP or the target sensing time window; when the first flag is set to a second parameter value, such as "0", it indicates that the first radio frame will not be transmitted again within the TXOP or the target sensing time window.
[0060] It is understood that the target TXOP is the TXOP in step 102 when the first radio frame is sent, and the target sensing time window is the sensing time window in step 102 when the first radio frame is sent.
[0061] Step 102: Send the first wireless frame.
[0062] The initiating end sends a first wireless frame, which carries a first identifier bit, so that the sensing response end can determine whether to receive the first wireless frame again based on the first identifier bit, thus improving the trigger-based TB-Based sensing measurement process.
[0063] See Figure 7 This disclosure also discloses a WLAN sensing measurement method. Optionally, the method can be applied to an electronic device, which can be a network device, such as a sensing initiator. Specifically, the method may include the following steps:
[0064] Step 701: When at least two sensing measurement events occur within the target TXOP or the target sensing time window, determine that the first flag bit instructs the sensing initiator to retransmit the first radio frame within the target TXOP or the target sensing time window.
[0065] The WLAN sensing measurement method provided in this disclosure uses the architecture and process of WLAN sensing as described in the first example above, and the TB-based sensing measurement process uses the second example above, which will not be repeated here.
[0066] In a TB-based scenario, when there are at least two sensing measurement events within the target TXOP or the target sensing time window, the initiating end sends a first radio frame at least once in each sensing measurement event. The first radio frame may be a polling frame or a trigger frame (TF).
[0067] Taking the first wireless frame as a polling frame as an example, in a WLAN sensing measurement process corresponding to the same WLAN Sensing Measurement Setup ID, if there are multiple measurement events, it is necessary to send polling frames multiple times to indicate that it contains multiple sensing measurement events. Therefore, in this embodiment of the disclosure, a first identifier bit is carried in the first wireless frame. The first identifier bit indicates whether the first wireless frame is sent again within the target TXOP or the target sensing time window, so as to indicate whether the sensing initiator will send the first wireless frame again later. It can be understood that the target TXOP is the TXOP in step 702 where the first wireless frame is sent, and the target sensing time window is the sensing time window in step 702 where the first wireless frame is sent.
[0068] Step 702: Send the first wireless frame.
[0069] The initiating end sends a first wireless frame, which carries a first identifier bit. This allows the sensing and response end to determine, based on the first identifier bit, that it needs to receive the first wireless frame again, thus improving the TB-Based sensing and measurement process.
[0070] See Figure 8 This disclosure also discloses a WLAN sensing measurement method. Optionally, the method can be applied to an electronic device, which can be a network device, such as a sensing initiator. Specifically, the method may include the following steps:
[0071] Step 801: Determine the first wireless frame; wherein the communication bandwidth of the first wireless frame does not include the uplink bandwidth of the sensing response end participating in the WLAN sensing measurement, and determine the first flag bit to indicate that the sensing initiator retransmits the first wireless frame within the target TXOP or the target sensing time window.
[0072] The WLAN sensing measurement method provided in this disclosure uses the architecture and process of WLAN sensing as described in the first example above, and the TB-based sensing measurement process uses the second example above, which will not be repeated here.
[0073] In a TB-based scenario, the communication bandwidth of the first wireless frame does not include the uplink bandwidth of the sensing response end participating in the WLAN sensing measurement. For example, if the first wireless frame is a polling frame, and the communication bandwidth (e.g., uplink communication bandwidth UL BW) of the polling frame is 80MHz, while the UL BW of the sensing response end in the sensing measurement event is 240MHz, then the communication bandwidth of the polling frame cannot completely detect all the sensing response ends participating in the WLAN sensing measurement, and the first wireless frame will be sent multiple times. Therefore, it is determined that the first flag indicates that the sensing initiator will send the first wireless frame again within the target TXOP or the target sensing time window.
[0074] It is understood that the target TXOP is the TXOP in step 802 when the first radio frame is sent, and the target sensing time window is the sensing time window in step 802 when the first radio frame is sent.
[0075] Step 802: Send the first wireless frame.
[0076] The initiating end sends a first wireless frame, which carries a first identifier bit. This allows the sensing and response end to determine, based on the first identifier bit, that it needs to receive the first wireless frame again, thus improving the TB-Based sensing and measurement process.
[0077] See Figure 9 This disclosure also discloses a WLAN sensing measurement method. Optionally, the method can be applied to an electronic device, which can be a network device, such as a sensing initiator. Specifically, the method may include the following steps:
[0078] Step 901, determine the first radio frame; wherein the first radio frame carries a first identifier bit, the first identifier bit indicating whether the first radio frame should be transmitted again within the target transmission opportunity TXOP or the target sensing time window.
[0079] Step 902: Send the first wireless frame.
[0080] Step 903: Determine the second identifier bit of the second wireless frame based on the first identifier bit; wherein the second identifier bit indicates whether the second wireless frame is transmitted again during the measurement process of the WLAN sensing measurement.
[0081] Taking the first wireless frame as a polling frame and the second wireless frame as a TF frame as an example; when the first flag bit of the polling frame indicates that the sensing initiator retransmits the first wireless frame within the target TXOP or the target sensing time window, that is, when the first flag bit of the polling frame indicates that a subsequent polling frame will be sent, then the corresponding second flag bit needs to be set in the uplink TF (trigger frame sounding) trigger frame to indicate that a subsequent trigger frame will be sent, that is, the second flag bit indicates that the second wireless frame will be sent again during the measurement process of the WLAN sensing measurement.
[0082] Step 904: Send the second wireless frame.
[0083] Optionally, in this embodiment of the present disclosure, the first identifier bit is carried in the public information field of the first wireless frame;
[0084] The first wireless frame is a trigger frame, the receiving address of the first wireless frame is a broadcast address or a multicast address, and the sending address of the first wireless frame is the MAC address of the sensing initiator.
[0085] The second identifier bit is carried in the common information field of the second radio frame;
[0086] and / or
[0087] The second wireless frame is a trigger frame, the receiving address of the second wireless frame is a broadcast address or a multicast address, and the sending address of the second wireless frame is the MAC address of the sensing initiator.
[0088] Both the first and second identifier bits are carried in the common info field. Among them, polling frames and TF sounding trigger frames are types of trigger frames. For example, in the common info field, different type values are used to identify polling frames and TF sounding trigger frames. For example, when the type value is the first identifier value, the first wireless frame is identified as a polling frame; when the type value is set to the second identifier value, the first wireless frame is identified as an (uplink) sensing trigger frame.
[0089] The receiving addresses of the first and second wireless frames are broadcast or multicast addresses, and the sending addresses are the Media Access Control (MAC) addresses of the sensing initiator.
[0090] In this embodiment of the present disclosure, a first wireless frame is determined and transmitted; wherein, the first wireless frame carries a first identifier bit, the first identifier bit indicating whether the first wireless frame is transmitted again within the target transmission opportunity TXOP or the target sensing time window, so that the sensing response end determines whether to receive the first wireless frame again according to the first identifier bit, thereby improving the TB-Based sensing measurement process.
[0091] See Figure 10 This disclosure provides a WLAN sensing measurement method. Optionally, the method can be applied to an electronic device, which can be a sensing response terminal. The method may include the following steps:
[0092] Step 1001: Receive a first wireless frame; wherein the first wireless frame carries a first identifier bit, the first identifier bit indicating whether the sensing initiator should retransmit the first wireless frame within the target transmission opportunity TXOP or the target sensing time window.
[0093] The WLAN sensing measurement method provided in this disclosure uses the architecture and process of WLAN sensing as described in the first example above, and the TB-based sensing measurement process uses the second example above, which will not be repeated here.
[0094] In TB-based scenarios, there may be situations where the same message frame needs to be sent multiple times, i.e., the first radio frame in this embodiment. The first radio frame is, for example, a polling frame or a trigger frame (TF). For example, the first radio frame also includes a second identifier bit, wherein when the second identifier bit is set to a first identifier value, the first radio frame is identified as a polling frame; when the second identifier bit is set to a second identifier value, the first radio frame is identified as an (uplink) sensing trigger frame.
[0095] Taking the first wireless frame as a polling frame as an example, in a WLAN sensing measurement process corresponding to the same WLAN Sensing Measurement Setup ID, if there are multiple measurement events, multiple polling frames need to be sent to indicate that it contains multiple sensing measurement events; or in a measurement event, since the sensing measurement bandwidth cannot meet the needs of all participating responders, multiple TF frames may be sent. Therefore, in this embodiment, a first identifier bit carried in the first wireless frame is obtained. The first identifier bit indicates whether the first wireless frame will be sent again within the target transmission opportunity (TXOP) or the target sensing time window, to indicate whether the sensing initiator will send the first wireless frame again later. For example, when the first identifier bit is set to a first parameter value, such as "1", the first wireless frame will be sent again within the target TXOP or the target sensing time window; when the first identifier bit is set to a second parameter value, such as "0", it indicates that the first wireless frame will not be sent again within the TXOP or the target sensing time window.
[0096] It is understood that the target TXOP is the TXOP of the first radio frame received in step 1002, and the target sensing time window is the sensing time window of the first radio frame received in step 1002.
[0097] Step 1002: Based on the first identifier bit, determine whether the first wireless frame is received again within the target TXOP or the target sensing time window.
[0098] The sensing response end determines whether the sensing initiator should send the first wireless frame again based on the first identifier bit, thereby determining whether to receive the first wireless frame again and improving the TB-Based sensing measurement process.
[0099] Optionally, in this embodiment of the disclosure, after receiving the first wireless frame, the method includes:
[0100] Based on the first identifier bit, a second identifier bit of the second wireless frame is determined; wherein, the second identifier bit indicates whether the sensing initiator retransmits the second wireless frame during the WLAN sensing measurement process;
[0101] Based on the second identifier bit, determine whether the second wireless frame is received again during the WLAN sensing measurement process.
[0102] In this case, taking the first wireless frame as a polling frame and the second wireless frame as a TF frame as an example; when the first flag bit of the polling frame indicates that the sensing initiator retransmits the first wireless frame within the target TXOP or the target sensing time window, that is, when the first flag bit of the polling frame indicates that a subsequent polling frame will be sent, the second flag bit in the corresponding TF sounding trigger frame indicates that a subsequent trigger frame will be sent, that is, the second flag bit indicates that the second wireless frame will be received again during the measurement process of the WLAN sensing measurement.
[0103] Optionally, in this embodiment of the present disclosure, the first identifier bit is carried in the public information field of the first wireless frame;
[0104] The first wireless frame is a trigger frame, the receiving address of the first wireless frame is a broadcast address or a multicast address, and the sending address of the first wireless frame is the MAC address of the sensing initiator.
[0105] The second identifier bit is carried in the common information field of the second radio frame;
[0106] and / or
[0107] The second wireless frame is a trigger frame, the receiving address of the second wireless frame is a broadcast address or a multicast address, and the sending address of the second wireless frame is the MAC address of the sensing initiator.
[0108] Both the first and second identifier bits are carried in the common info field. Among them, polling frames and TF sounding trigger frames are types of trigger frames. For example, in the common info field, different type values are used to identify polling frames and TF sounding trigger frames. For example, when the type value is the first identifier value, the first wireless frame is identified as a polling frame; when the type value is set to the second identifier value, the first wireless frame is identified as an (uplink) sensing trigger frame.
[0109] The receiving addresses of the first and second wireless frames are broadcast or multicast addresses, and the sending addresses are the Media Access Control (MAC) addresses of the sensing initiator.
[0110] In this embodiment of the present disclosure, a first wireless frame is received; wherein the first wireless frame carries a first identifier bit, the first identifier bit indicating whether the first wireless frame is retransmitted within the target transmission opportunity TXOP or the target sensing time window, so that the sensing response end determines whether to receive the first wireless frame again based on the first identifier bit, thereby improving the TB-Based sensing measurement process.
