Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.
[0045] The embodiments of the present disclosure provide a communication method and apparatus, an electronic device, and a storage medium, which are used to solve the problem that a large number of termination message frames will occupy more network resources.
[0046] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.
[0047] like Figure 1 As shown in , an embodiment of the present disclosure provides a communication method. Optionally, the method may be applied to a network device, which serves as a perception initiator during a perception measurement process; for example, an access point device AP. The method may include the following steps:
[0048] Step 101: determine a target radio frame; wherein the target radio frame includes a multi-user physical layer protocol data unit MU-PPDU, and the MU-PPDU includes a perception measurement establishment termination message frame corresponding to at least two perception responders.
[0049] As a first example, see Figures 2 to 4 First, the architecture and process of WLAN Sensing applied to the communication method provided in the embodiment of the present disclosure are introduced.
[0050] Figure 2The schematic diagram of the architecture of a WLAN Sensing (process) is shown; wherein the sensing initiator (or initiator) initiates WLAN Sensing (for example, initiates a WLAN sensing session), and there may be multiple sensing responders (or sensing receivers) or responders responding to it, such as Figure 2 As shown in the responding end 1, responding end 2 and responding end 3 in FIG. When the sensing initiator initiates WLAN Sensing, multiple associated or unassociated WLAN Sensing sensing responding ends can respond.
[0051] See also Figure 3 , the perception initiator and the perception responder communicate through a communication connection, as shown by communication connection S1; the perception responders communicate with each other through communication connection S2.
[0052] Each sensing initiator can be a client; each sensing responder (in this example, sensing responders 1 to 3) can be a station (STA) or access point (AP). Furthermore, STAs and APs can assume multiple roles during the WLAN sensing process. For example, during the WLAN sensing process, a STA can also serve as a sensing initiator, which can be a sensing transmitter, a sensing receiver, both, or neither. During the WLAN sensing process, a sensing responder can also be a sensing transmitter, a sensing receiver, or both.
[0053] As another architecture, Figure 4 As shown, the sensing initiator and the sensing responder can also be clients, and the two can communicate by connecting to the same access point device (AP); Figure 4 Client1 is the perception initiator, and Client2 is the perception responder.
[0054] Generally, the WLAN sensing process includes the establishment of a WLAN sensing session, the establishment of WLAN sensing measurements, and the termination of WLAN sensing measurements. The WLAN sensing process generally includes a Triggered Based Sounding (TB)-based method and a Non-TB based sensing method. Specifically, the TB-based method is that the AP is the Initiator or Transmitter, and the Non-TB Based method is that the STA is the Initiator or Transmitter. In the TB Based scenario, the AP, as the perception initiator, can initiate the termination of one or more sensing measurement settings by sending a perception measurement establishment termination message frame to the STA, which is the perception responder; however, a large number of perception measurement establishment termination message frames will occupy more network resources; and, generally, after the AP sends the perception measurement establishment termination message frame, the STA will reply with a confirmation message (such as an ACK frame), which will further occupy network resources and affect the effective use of the spectrum. In an embodiment of the present disclosure, an AP determines a target radio frame, where the target radio frame includes a multi-user physical layer protocol data unit (MU-PPDU); wherein the MU-PPDU includes a perception measurement establishment termination message frame corresponding to at least two perception response ends, that is, the MU-PPDU includes perception measurement establishment termination message frames corresponding to multiple STAs, respectively, and the MU-PPDU includes a PPDU for multiple users (STAs), and each user's PPDU includes a perception measurement establishment termination message frame of the STA.
[0055] The perception measurement establishment termination frame is a unicast message frame.
[0056] Optionally, the MU-PPDU may be downlink orthogonal frequency division multiple access (DL Orthogonal Frequency Division Multiple Access, DL OFDMA), downlink multi-user multiple input multiple output (DL MU-Multi-Input Multi-Output, DL MU-MIMO) or a combination of the two.
[0057] Optionally, the PPDU includes a physical layer header preamble (PLCP Header preamble) and a MAC Protocol Data Unit (MAC Protocol Data Unit, MPDU), or a PLCP Header preamble and an aggregation of the MPDUs (A-MPDU).
[0058] Step 102: Send the target wireless frame to at least two of the perception response terminals simultaneously.
[0059] After determining the target wireless frame, the target wireless frame is sent to multiple perception response ends at the same time; in this way, through one sending operation, multiple response ends can receive the perception measurement establishment termination message frame corresponding to the response end, so as to reduce the sending operation of the perception measurement establishment termination message frame and reduce the occupancy of spectrum resources.
[0060] For a responder that does not support the MU format, since it also initiates 1v1 perception measurement during the perception measurement process, the AP can initiate a separate perception measurement establishment and termination process.
[0061] In an embodiment of the present disclosure, a perception initiator determines a target radio frame and simultaneously sends the target radio frame to at least two perception responders; wherein the target radio frame includes an MU-PPDU, and the MU-PPDU includes a perception measurement establishment termination message frame corresponding to at least two perception responders, thereby reducing the number of times the perception measurement establishment termination message frame is sent, reducing the occupancy of spectrum resources, and improving frequency resource utilization; the embodiment of the present disclosure solves the problem that a large number of termination message frames will occupy more network resources during the WLAN perception termination process.
[0062] In an optional embodiment, the MU-PPDU further includes a trigger frame (trigger frame) corresponding to each of the perception measurement establishment termination frames;
[0063] The trigger frame indicates an uplink resource unit configured for the perception response end, and the uplink resource unit carries a confirmation message in which the perception response end replies to the perception measurement setup termination frame.
[0064] Among them, the trigger frame is used to indicate the uplink resource unit (RU) configured for the perception response end, and the RU is used to carry the confirmation message (e.g., uplink ACK frame) of the perception response end in reply to the perception measurement establishment termination frame. For example, the RU is 26-tone (subcarrier), 52-tone, or the MRU is 106+52, 52+26tone, and so on.
[0065] See also Figure 5The present disclosure provides a communication method. Optionally, the method may be applied to a network device that acts as a perception initiator during a perception measurement process; for example, an access point device (AP). The method may include the following steps:
[0066] Step 501: Determine a target radio frame; wherein the target radio frame includes a multi-user physical layer protocol data unit MU-PPDU, and the MU-PPDU includes a perception measurement establishment termination message frame corresponding to at least two perception responders; the MU-PPDU target radio frame also includes a trigger frame corresponding to each of the perception measurement establishment termination frames.
[0067] The trigger frame indicates an uplink resource unit configured for the perception response end, and the uplink resource unit carries a confirmation message in which the perception response end replies to the perception measurement setup termination frame.
[0068] The MU-PPDU includes an aggregated first MAC protocol data unit MPDU; the aggregated first MPDU includes the aggregated perception measurement setup termination frame and the aggregated trigger frame.
[0069] Among them, the architecture of WLAN Sensing applied in the communication method provided in the embodiment of the present disclosure and the WLAN Sensing process refer to the above-mentioned first example and are not repeated here.
[0070] In an embodiment of the present disclosure, the AP determines a target wireless frame, where the target wireless frame includes a MU-PPDU; the MU-PPDU includes a PPDU for multiple users (STAs), and each user's PPDU includes a perception measurement establishment termination message frame and a trigger frame of the STA.
[0071] Specifically, the MU-PPDU includes an aggregated first MAC protocol data unit MPDU; for example, in a DL OFDMA format or a DL MU-MIMO format, the AP sends the aggregated first MPDU in the form of a MU-PPDU (the aggregated first MPDU is subsequently represented by an A-MPDU), and the A-MPDU includes the aggregated perception measurement establishment termination frame and the aggregated trigger frame.
[0072] Among them, in the A-MPDU, the perception measurement establishment termination frame and the trigger frame are both unicast message frames, and the AP aggregates them respectively to form an A-MPDU for transmission; for example, multiple perception measurement establishment termination frames are aggregated, and multiple trigger frames are aggregated to form an A-MPDU.
[0073] Step 502: Send the target wireless frame to at least two of the sensing response terminals simultaneously.
[0074] After determining the target wireless frame, the target wireless frame is sent to multiple perception response ends at the same time; in this way, through one sending operation, multiple response ends can receive the perception measurement establishment termination message frame corresponding to the response end, so as to reduce the sending operation of the perception measurement establishment termination message frame and reduce the occupancy of spectrum resources.
[0075] See also Figure 6 The present disclosure provides a communication method. Optionally, the method may be applied to a network device that acts as a perception initiator during a perception measurement process; for example, an access point device (AP). The method may include the following steps:
[0076] Step 601: Determine a target radio frame; wherein the target radio frame includes a multi-user physical layer protocol data unit MU-PPDU, and the MU-PPDU includes a perception measurement establishment termination message frame corresponding to at least two perception responders; the MU-PPDU target radio frame also includes a trigger frame corresponding to each of the perception measurement establishment termination frames.
[0077] The trigger frame indicates an uplink resource unit configured for the perception response end, and the uplink resource unit carries a confirmation message in which the perception response end replies to the perception measurement setup termination frame.
[0078] The MU-PPDU includes a second MPDU; the second MPDU includes the perception measurement setup termination frame and the trigger frames respectively corresponding to the perception measurement setup termination frames.
[0079] Among them, the architecture of WLAN Sensing applied in the communication method provided in the embodiment of the present disclosure and the WLAN Sensing process refer to the above-mentioned first example and are not repeated here.
[0080] In an embodiment of the present disclosure, the AP determines a target wireless frame, where the target wireless frame includes a MU-PPDU; the MU-PPDU includes a PPDU for multiple users (STAs), and each user's PPDU includes a perception measurement establishment termination message frame and a trigger frame of the STA.
[0081] Specifically, the MU-PPDU includes a second MPDU; the second MPDU includes the perception measurement establishment termination frame and the trigger frames corresponding to the perception measurement establishment termination frames respectively; that is, in the second MPDU, the perception measurement establishment termination frame of each STA is set in a one-to-one correspondence with the trigger frame of the STA, for example, after a short interframe space (SIFS) after sending the perception measurement establishment termination message frame, the AP sends the trigger frame of the STA again.
[0082] Step 602: Send the target wireless frame to at least two of the perception response terminals simultaneously.
[0083] After determining the target wireless frame, the target wireless frame is sent to multiple perception response ends at the same time; in this way, through one sending operation, multiple response ends can receive the perception measurement establishment termination message frame corresponding to the response end, so as to reduce the sending operation of the perception measurement establishment termination message frame and reduce the occupancy of spectrum resources.
[0084] In an embodiment of the present disclosure, a perception initiator determines a target wireless frame and simultaneously sends the target wireless frame to at least two perception responders; wherein the target wireless frame includes an MU-PPDU, and the MU-PPDU includes a perception measurement establishment termination message frame corresponding to at least two perception responders, thereby reducing the number of times the perception measurement establishment termination message frame is sent, reducing the occupancy of spectrum resources, and improving frequency resource utilization.
[0085] In the above embodiment, the AP initiates the sending of a perception measurement setup termination frame as an MU user. The first aggregated MPDU includes the aggregated perception measurement setup termination frame and the aggregated trigger frame, and the second MPDU includes the perception measurement setup termination frame and the trigger frames corresponding to the perception measurement setup termination frames. In the above two methods, because the lengths of the unicast perception measurement setup termination message frames sent by the AP vary (including the number of measurement setup IDs), padding may be added to some short frames.
[0086] See also Figure 7 The present disclosure provides a communication method. Optionally, the method may be applied to an electronic device, which may be a station device STA. The station device STA is a first perception responder (hereinafter referred to as STA1). The method includes:
[0087] Step 701: Receive a target radio frame; wherein the target radio frame includes a multi-user physical layer protocol data unit MU-PPDU, and the MU-PPDU includes a perception measurement establishment termination message frame corresponding to at least two perception responders.
[0088] Among them, the architecture of WLAN Sensing applied in the communication method provided in the embodiment of the present disclosure and the WLAN Sensing process refer to the above-mentioned first example and are not repeated here.
[0089] Generally, the WLAN sensing process includes the establishment of a WLAN sensing session, the establishment of WLAN sensing measurements, and the termination of WLAN sensing measurements. The WLAN sensing process generally includes a TB-Based method and a Non-TB based sensing method. Specifically, the TB-based method is that the AP is the Initiator or Transmitter, and the Non-TB Based method is that the STA is the Initiator or Transmitter. In the TB Based scenario, the AP, as the perception initiator, can initiate the termination of one or more sensing measurement settings by sending a perception measurement establishment termination message frame to the STA, which is the perception responder; however, a large number of perception measurement establishment termination message frames will occupy more network resources; and, generally, after the AP sends the perception measurement establishment termination message frame, the STA will reply with a confirmation message (such as an ACK frame), which will further occupy network resources and affect the effective use of the spectrum. In an embodiment of the present disclosure, a first perception response end receives a target wireless frame, where the target wireless frame includes a MU-PPDU; wherein the MU-PPDU includes a perception measurement establishment termination message frame corresponding to at least two perception response ends, that is, the MU-PPDU includes perception measurement establishment termination message frames corresponding to multiple STAs, respectively, and the MU-PPDU includes a PPDU for multiple users (STAs), and the PPDU of each user includes the perception measurement establishment termination message frame of the STA.
[0090] The perception measurement establishment termination frame is a unicast message frame.
[0091] Optionally, the MU-PPDU may be downlink orthogonal frequency division multiple access (DL Orthogonal Frequency Division Multiple Access, DL OFDMA), downlink multi-user multiple input multiple output (DL MU-Multi-Input Multi-Output, DL MU-MIMO) or a combination of the two.
[0092] Optionally, the PPDU includes a physical layer header preamble (PLCP Header preamble) and a MAC Protocol Data Unit (MAC Protocol Data Unit, MPDU), or a PLCP Header preamble and an aggregation of the MPDUs (A-MPDU).
[0093] Step 702: Obtain a first perception measurement establishment termination frame corresponding to the first perception responder in the MU-PPDU.
[0094] After receiving the target wireless frame, STA1 obtains a first sensing measurement setup termination frame corresponding to the first sensing responder and terminates the sensing measurement process based on the first sensing measurement setup termination frame. In this way, through a single transmission operation by the sensing initiator, multiple sensing responders can receive the sensing measurement setup termination message frame corresponding to the responder, thereby reducing the number of sensing measurement setup termination message frame transmission operations and reducing spectrum resource usage.
[0095] In an embodiment of the present disclosure, a first perception response end receives a target wireless frame and obtains a first perception measurement establishment termination frame corresponding to the first perception response end in the MU-PPDU; wherein the target wireless frame includes the MU-PPDU, and the MU-PPDU includes a perception measurement establishment termination message frame corresponding to at least two perception response ends, which can reduce the number of times the perception measurement establishment termination message frame is sent, reduce the occupancy of spectrum resources, and improve frequency resource utilization.
[0096] See also Figure 8 The present disclosure provides a communication method. Optionally, the method may be applied to an electronic device, where the electronic device may be a station device STA, and the station device STA is a first perception responder. The method includes:
[0097] Step 801: Receive a target radio frame; wherein the target radio frame includes a multi-user physical layer protocol data unit MU-PPDU, and the MU-PPDU includes a sensing measurement establishment termination message frame corresponding to at least two sensing responders;
[0098] The MU-PPDU also includes a trigger frame (trigger frame) corresponding to each of the sensing measurement establishment termination frames;
[0099] The trigger frame indicates an uplink resource unit configured for the perception response end, and the uplink resource unit carries a confirmation message in which the perception response end replies to the perception measurement setup termination frame.
[0100] The trigger frame is used to indicate the uplink resource unit (RU) configured for the perception responder, and the RU is used to carry the confirmation message (eg, uplink ACK frame) of the perception responder in reply to the perception measurement setup termination frame.
[0101] Step 802: Obtain a first perception measurement establishment termination frame corresponding to the first perception responder in the MU-PPDU.
[0102] Step 803: Send the confirmation message in the first uplink resource unit corresponding to the first perception measurement establishment termination frame.
[0103] STA1 replies with a confirmation message in the first uplink resource unit, instructing the AP to confirm receipt of the first perception measurement establishment termination frame; after replying to the AP confirmation message, STA1 may terminate the perception measurement process.
[0104] In an optional embodiment, the MU-PPDU includes an aggregated first MAC protocol data unit MPDU; the aggregated first MPDU includes the aggregated perception measurement setup termination frame and the aggregated trigger frame.
[0105] Specifically, the MU-PPDU includes an aggregated first MAC protocol data unit MPDU; for example, in a DL OFDMA format or a DL MU-MIMO format, the AP sends the aggregated first MPDU in the form of a MU-PPDU (the aggregated first MPDU is subsequently represented by an A-MPDU), and the A-MPDU includes the aggregated perception measurement establishment termination frame and the aggregated trigger frame.
[0106] Among them, in the A-MPDU, the perception measurement establishment termination frame and the trigger frame are both unicast message frames, and the AP aggregates them respectively to form an A-MPDU for transmission; for example, multiple perception measurement establishment termination frames are aggregated, and multiple trigger frames are aggregated to form an A-MPDU.
[0107] In an optional embodiment, the MU-PPDU includes a second MPDU; the second MPDU includes the perception measurement setup termination frame and the trigger frames respectively corresponding to the perception measurement setup termination frames.
[0108] The MU-PPDU includes a PPDU for multiple users (STAs), and the PPDU of each user includes a perception measurement establishment termination message frame and a trigger frame of the STA.
[0109] Specifically, the MU-PPDU includes a second MPDU; the second MPDU includes the perception measurement establishment termination frame and the trigger frames corresponding to the perception measurement establishment termination frames respectively; that is, in the second MPDU, the perception measurement establishment termination frame of each STA is set in a one-to-one correspondence with the trigger frame of the STA, for example, after a short interframe space (SIFS) after sending the perception measurement establishment termination message frame, the AP sends the trigger frame of the STA again.
[0110] In the above embodiment, the AP initiates the sending of a perception measurement setup termination frame as an MU user. The first aggregated MPDU includes the aggregated perception measurement setup termination frame and the aggregated trigger frame, and the second MPDU includes the perception measurement setup termination frame and the trigger frames corresponding to the perception measurement setup termination frames. In the above two methods, because the lengths of the unicast perception measurement setup termination message frames sent by the AP vary (including the number of measurement setup IDs), padding may be added to some short frames.
[0111] In an embodiment of the present disclosure, a first perception response end receives a target wireless frame and obtains a first perception measurement establishment termination frame corresponding to the first perception response end in the MU-PPDU; wherein the target wireless frame includes the MU-PPDU, and the MU-PPDU includes a perception measurement establishment termination message frame corresponding to at least two perception response ends, which can reduce the number of times the perception measurement establishment termination message frame is sent, reduce the occupancy of spectrum resources, and improve frequency resource utilization.
