[0024] Figure 1 This illustrates an exemplary way of WLAN awareness.
[0025] 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.
[0026] 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.
[0027] 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.
[0028] 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.
[0029] 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.
[0030] 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.
[0031] Although Figure 1 As shown in (a), (b), and (c), 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. In embodiments of this disclosure, the client can refer to a non-AP site, simply referred to as a "site (STA)". 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.
[0032] As an illustrative embodiment, the WLAN sensing process may include: WLAN sensing session establishment, WLAN sensing measurement establishment, WLAN sensing measurement, and WLAN sensing measurement feedback. During WLAN sensing session establishment, operating parameters associated with the sensing session can be determined and exchanged between devices. Furthermore, one WLAN sensing session establishment may include multiple WLAN sensing measurement establishments. In one WLAN sensing measurement establishment, operating parameters for the sensing measurement can be defined, and one or more sensing measurement events can be included. During WLAN sensing measurement, one or more WLAN sensing measurement events can be executed to obtain WLAN sensing measurement results. During WLAN sensing measurement feedback, the WLAN sensing measurement results can be fed back.
[0033] WLAN sensing can be applied in the 60GHz spectrum, and the process can be as follows: Figure 2 As shown.
[0034] Figure 2 This illustration depicts the establishment of a WLAN sensing session and a WLAN sensing measurement setup under that session. However, this disclosure is not limited to this; the WLAN sensing process may include multiple WLAN sensing session establishments, and each WLAN sensing session establishment may contain multiple WLAN sensing measurement setups. In a WLAN sensing session establishment, the initiator's MAC (Media Access Control Address) address (ADDR) and the responder's identifier AID can be identified. In a WLAN sensing measurement setup, a measurement setup identifier (Measurement Setup ID) and the initiator's MAC ADDR can be identified.
[0035] Each WLAN sensing measurement setup can contain one or more bursts, and each burst can contain one or more WLAN sensing measurement events. Figure 2 This is illustrated as a "sensing instance". A burst represents a specific time interval, and one or more WLAN sensing measurement events can be performed within a burst. Although in Figure 2 Two bursts (Butt 1 and Burst 2) are shown, and each burst includes three WLAN sensing measurement events (sensing instances). However, this is only an instance and the disclosure is not limited thereto. The number of bursts in each WLAN sensing measurement setup and the number of sensing instances in each burst can be changed differently.
[0036] Continue to refer to Figure 2Each WLAN sensing measurement event can have a corresponding identifier (Instance#), and can correspond to a measurement setup identifier (Setup ID) and a burst identifier (Burst ID). The time interval between adjacent WLAN sensing measurement events within a burst can be called the intra-burst interval, and the time interval between adjacent bursts can be called the inter-burst interval.
[0037] WLAN sensing measurement feedback can be performed by sending a sensing measurement report frame, which can be initiated by an MLME (MAC sublayer management entity) source. Furthermore, WLAN sensing measurement feedback can be performed using either immediate or delayed reporting. In the following text, immediate reporting may also be referred to as immediate feedback, and delayed reporting as delayed feedback. In immediate reporting, the sensing measurement result is fed back immediately whenever a sensing measurement event is executed. In delayed reporting, the sensing measurement result can be fed back after multiple sensing measurement events have been executed. For example, in delayed reporting, the sensing measurement results of one or more WLAN sensing measurement establishments (multiple WLAN sensing measurement events) by the sensing responder can be included in a single sensing measurement report frame. The sensing initiator may optionally support retrieving multiple sensing measurement results in a single sensing measurement report frame sent by the sensing responder.
[0038] The above description of WLAN sensing measurement feedback (timely feedback and delayed feedback) can be applied to DMG (directional multi-Gigabit) / EDMG (enhanced DMG). However, in current research, a complete feedback mechanism is lacking for the time slots of WLAN sensing measurement feedback.
[0039] In view of this, a communication method and communication apparatus for WLAN sensing measurement feedback according to embodiments of the present disclosure are provided.
[0040] Figure 3 This is a flowchart illustrating a communication method according to an example embodiment. Figure 2 The communication method shown can be applied to the initiator of WLAN sensing. For example, the initiator of WLAN sensing can be an Access Point (AP).
[0041] Reference Figure 3 In step 310, a sensing measurement establishment message frame is determined. The sensing measurement establishment message frame can be used to establish WLAN sensing measurements (such as...). Figure 2 The frame is used for measurement establishment in WLAN, and various information for WLAN sensing measurement and feedback can be defined. In embodiments of this disclosure, there are many ways to determine the sensing measurement establishment message frame. For example, the sensing measurement establishment message frame can be generated or configured according to at least one of the following: channel state, network condition, load condition, device hardware capabilities, service type, and relevant protocol specifications; this disclosure does not impose specific limitations on this.
[0042] According to one embodiment of this disclosure, a sensing measurement establishment message frame may include first information associated with a timeslot for WLAN sensing measurement feedback, wherein the timeslot may represent the time interval for feeding back sensing measurement results. That is, information related to the timeslot for WLAN sensing measurement feedback can be defined in the WLAN sensing measurement establishment (also referred to as a "sensing measurement establishment operation").
[0043] The time slots for WLAN sensing measurement feedback can have different time intervals. The first information in the sensing measurement setup message frame can include corresponding information depending on the different time intervals of the time slots. The first information can be determined in the sensing measurement setup message frame to identify the time slot for feeding back the sensing measurement results. See below for further details. Figure 4 Provide a detailed description.
[0044] According to another embodiment of this disclosure, the sensing measurement establishment message frame may further include second information for identifying the mode of WLAN sensing measurement feedback, wherein the mode may include an immediate feedback mode or a delayed feedback mode. The first information in the sensing measurement establishment message frame may differ depending on the feedback mode identified in the second information. Referring later... Figure 4 Provide a detailed description.
[0045] Continue to refer to Figure 3 In step 320, a sensing measurement setup message frame is sent. The initiator sends a sensing measurement setup message frame containing relevant information about the time slot for WLAN sensing measurement feedback to the responder, so that the initiator can receive the sensing measurement results reported by the responder based on the feedback time slot.
[0046] According to one embodiment of this disclosure, Figure 4 This is a flowchart illustrating the establishment of a message frame based on a determined sensing measurement according to an example embodiment.
[0047] Reference Figure 4 The method for determining the establishment of a message frame by sensing measurements may include: determining first information (step 410); determining second information (step 420). It will be understood that, although in Figure 4As shown, steps 410 and 420 are performed separately and sequentially. However, this disclosure is not limited thereto. For example, steps 410 and 420 may be performed simultaneously, or the execution order of steps 410 and 420 may be changed, or step 420 may be omitted. Alternatively, the determination of the perception measurement establishment message frame may also include steps for determining other additional information.
[0048] In step 410, the first information can be determined in association with the time slot of the WLAN sensing measurement feedback. In other words, the content of the first information in the sensing measurement establishment message frame can be determined. According to embodiments of this disclosure, the first information may include one of the following:
[0049] Information used to identify feedback for each measurement event;
[0050] Information used to identify feedback at every specific number of perceived measurement events;
[0051] Information used to identify feedback at intervals of a specific number of bursts;
[0052] Information used to identify feedback generated at every certain number of sensing measurements.
[0053] For example, the first information can be carried in the perception measurement establishment message frame in the format of information elements (e.g., but not limited to, information elements for measurement feedback). Specifically, to identify the time slots for WLAN sensing measurement feedback, the determined first information may include an instance interval of intra-burst field; the determined first information may also optionally include a number of instances field and / or an interval between instances for delayed feedback field; the determined first information may optionally include a number of bursts field and / or an interval between bursts for delayed feedback field; the determined first information may optionally include an interval of inter-burst field and / or a duration of a burst field; the determined first information may optionally include a number of measurement setups field and / or an interval between measurement setups for delayed feedback field; the determined first information may optionally include an interval between adjacent measurement setups field and / or a duration of a measurement setup field. However, this is merely exemplary and not a limitation of this disclosure. For example, when the first information has an information element format, in addition to the fields shown above, the first information having an information element format may also include various other information, such as element identifiers, extension identifiers, lengths, etc.
[0054] In step 420, the method of WLAN sensing measurement feedback (second information) can be determined; in other words, the content of the second information in the sensing measurement establishment message frame can be determined.
[0055] In one embodiment of this disclosure, a bit in the message frame established by sensing measurements can be used to explicitly identify either a timely feedback mode or a delayed feedback mode. For example, a bit of "0" can indicate a timely feedback mode, in which case the first information may not include information between bursts, such as the interval of inter-burst. Conversely, a bit of "1" can indicate a delayed feedback mode, in which case the first information may not include information between events, such as the instance interval of intra-burst.
[0056] If the WLAN sensing measurement feedback method (second information) is different, the first information may contain different information. For example, if the second information identifies an immediate feedback method, the first information may include information for identifying feedback for each measurement event (as shown in Table 1 below). For example, if the second information identifies a delayed feedback method, the first information may include one of the following:
[0057] Information used to identify feedback at every certain number of perceived measurement events (as shown in Table 2 below);
[0058] Information used to identify feedback at intervals of a specific number of bursts (as shown in Tables 3 and 4 below);
[0059] Information used to identify feedback from operations established at every specific number of sensing measurements (as shown in Tables 5 and 6 below).
[0060] In another embodiment of this disclosure, the second information can be identified implicitly. In other words, step 420 can be omitted, or the specific bits in the sensing measurement establishment message frame can be used instead of the specific bits to identify the WLAN sensing measurement feedback method. Instead, the timely feedback method or the delayed feedback method can be implicitly identified directly through the different fields contained in the first information. For example, the first information shown in Table 1 below can correspond to the timely feedback method, and the second information shown in Tables 2 to 6 below can correspond to the delayed feedback method.
[0061] Reference Figure 3 and Figure 4 The described communication method improves the feedback time slot of measurement results in DMG / EDMG application scenarios, and can better meet the needs of WLAN sensing.
[0062] In one embodiment of this disclosure, a method for determining WLAN sensing measurement feedback time slots is provided. In this method, information identifying feedback for each measurement event can be determined during the sensing measurement setup process. For ease of description, this information may be referred to hereinafter as first information. This method can be used to define measurement result feedback time slots in a DMG / EDMG application scenario. In this case, the WLAN sensing measurement feedback time slot may refer to the time interval between adjacent measurement events within each burst. For example, as shown in Table 1, the determined first information may include an instance interval of intra-burst field to identify information feedback for each measurement event.
[0063] Table 1
[0064] Instance interval of intra-burst
[0065] In Table 1, the "Instance interval of intra-burst" field can be used to indicate when the measurement result is fed back (or reported) each time a WLAN sensing measurement event is performed. In other words, Table 1 can correspond to a timely feedback method.
[0066] In another embodiment of this disclosure, a method for determining WLAN sensing measurement feedback time slots is provided. In this method, information including information for identifying feedback at intervals of a specific number of sensing measurement events can be determined during the sensing measurement setup process. For ease of description, this information may be referred to hereinafter as first information. In this case, the WLAN sensing measurement feedback time slot may refer to the time interval between a specific number of sensing measurement events for which sensing measurement results need to be fed back. For example, when the specific number of sensing measurement events refers to n sensing measurement events (n is an integer greater than or equal to 2), the WLAN sensing measurement feedback time slot may refer to the time interval between every n sensing measurement events, such as the time interval between the first sensing measurement event and the (n+1)th sensing measurement event, and the time interval between the (n+1)th sensing measurement event and the (2n+1)th sensing measurement event, etc.
[0067] For example, as shown in Table 2, the first information identified may optionally include a number of instances field and / or an interval between instances for delayed feedback field to identify the time slots of WLAN sensing measurement feedback.
[0068] Table 2
[0069] Number of instances Interval between instances for delayed feedback
[0070] In Table 2, the "Number of instances" field indicates how many sensing measurement events are followed by feedback, and the "Interval between instances for delayed feedback" field indicates the time interval between a specific number of sensing measurement events for which feedback results are required. For example, but not limited to, when feedback is followed by every two sensing measurement events, the "Number of instances" field in Table 2 can be identified as the number 2, or the "Interval between instances for delayed feedback" field can be identified as the time interval between every two sensing measurement events.
[0071] It will be understood that the first information may include only one of the two fields in Table 2, or may include both, or may include other fields. Furthermore, a specific number of sensing measurement events may be included within the same burst, or may be included within different bursts, which can be determined based on the duration of each measurement establishment, the duration of each burst, the number of WLAN sensing measurement events (sensing instances) within each burst, etc.
[0072] In another embodiment of this disclosure, a method for determining WLAN sensing measurement feedback time slots is provided. In this method, information for identifying feedback at intervals of a specific number of bursts can be determined during the sensing measurement setup process. For ease of description, this information may be referred to hereinafter as first information. In this case, the WLAN sensing measurement feedback time slot may refer to the time interval between a specific number of bursts for which sensing measurement results need to be fed back. For example, when the specific number of bursts refers to m bursts (m is an integer greater than or equal to 1), the WLAN sensing measurement feedback time slot may refer to the time interval between every m bursts, such as the time interval between the first burst and the (m+1)th burst, and the time interval between the (m+1)th burst and the (2m+1)th burst, etc.
[0073] For example, as shown in Table 3, the first information determined may optionally include a number of bursts field and / or an interval between bursts for delayed feedback field to identify the time slots of WLAN sensing measurement feedback.
[0074] Table 3
[0075] Number of bursts Interval between bursts for delayed feedback
[0076] In Table 3, the "Number of bursts" field indicates how many bursts feedback is performed at a time, and the "Interval between bursts for delayed feedback" field indicates the time interval between a specific number of bursts that require feedback of the sensing measurement results. For example, but not limited to, when feedback is performed every 2 bursts, the "Number of bursts" field in Table 3 can be identified as the number 2, or the "Interval between bursts for delayed feedback" field can be identified as the time interval between 2 bursts.
[0077] In another embodiment of this disclosure, a method for determining WLAN sensing measurement feedback time slots is provided. In this method, information for identifying feedback after every burst can be determined during the sensing measurement setup process. For ease of description, this information may be referred to hereinafter as first information. In other words, when the burst quantity field in Table 3 above is identified as quantity 1 or omitted, feedback after each burst can be identified. In this case, the determined first information may include the information shown in Table 4 below.
[0078] Table 4
[0079] Interval of inter-burst Duration of a burst
[0080] In Table 4, the time slots for WLAN sensing measurement feedback are identified using the Interval of inter-burst field and / or the Duration of a burst, i.e., feedback occurs after each burst. However, Table 4 provides a non-limiting embodiment; for example, Table 4 may also include a Number of bursts field (identified as 1) and the Instance number of aburst.
[0081] In another embodiment of this disclosure, a method for determining WLAN sensing measurement feedback time slots is provided. In this method, information including information for identifying feedback at every specific number of sensing measurement establishment operations can be determined during the sensing measurement establishment process. For ease of description, this information may be referred to hereinafter as first information. In this case, the WLAN sensing measurement feedback time slot may refer to the time interval between a specific number of sensing measurement establishment operations for which sensing measurement results need to be fed back. For example, when the specific number of sensing measurement establishment operations refers to t sensing measurement establishment operations (t being an integer greater than or equal to 1), the WLAN sensing measurement feedback time slot may refer to the time interval between every t sensing measurement establishment operations, such as the time interval between the first sensing measurement establishment operation and the (t+1)th sensing measurement establishment operation, and the time interval between the (t+1)th sensing measurement establishment operation and the (2t+1)th sensing measurement establishment operation, etc.
[0082] For example, as shown in Table 5, the determined first information may optionally include the number of measurement setups field and / or the interval between measurement setups for delayed feedback field to identify the time slots of WLAN sensing measurement feedback.
[0083] Table 5
[0084] Number of measurement setups Interval between measurement setups for delayed feedback
[0085] In Table 5, the "Number of measurement setups" field indicates the interval between each set of sensing measurement setups for feedback, and the "Interval between measurement setups for delayed feedback" field indicates the time interval between a specific number of sensing measurement setups for which feedback of sensing measurement results is required. For example, but not limited to, when feedback is provided every two measurement setups, the "Number of measurement setups" field in Table 5 can be identified as the number 2, or the "Interval between measurement setups for delayed feedback" field can be identified as the time interval between two measurement setups.
[0086] In another embodiment of this disclosure, a method for determining WLAN sensing measurement feedback time slots is provided. In this method, information for identifying feedback after every sensing measurement establishment can be determined during the sensing measurement establishment process. For ease of description, this information may be referred to hereinafter as first information. In other words, when the measurement establishment quantity field in Table 5 above is identified as quantity 1 or omitted, feedback can be identified after each sensing measurement establishment operation. In this case, the determined first information may include information as shown in Table 6 below.
[0087] Table 6
[0088] Interval between adjacent measurement setup Duration of a measurement setup
[0089] In Table 6, the time slots for WLAN sensing measurement feedback can be identified using the interval between adjacent measurement setups and / or the duration of each measurement setup, i.e., feedback occurs after each measurement setup. However, Table 6 is only a non-limiting embodiment. For example, Table 6 may also include a measurement setup quantity field (identified as quantity 1), or alternatively, it may include the instance number of a measurement setup, the burst number of a measurement setup, etc.
[0090] Furthermore, it will be understood that the examples of the first information described with reference to Tables 1 to 6 are merely illustrative and this disclosure is not limited thereto. For example, the first information may also include time synchronization function (TSF) information. Specifically, in the absence of an initial association between the initiator (e.g., AP) and the responder (e.g., STA), the first information may include TSF information for time synchronization between the initiator and the responder (e.g., TSF information is included in Tables 1 to 6), or the first information field TSF information may be separately identified in different fields of the sensing measurement establishment message frame.
[0091] Furthermore, although Tables 1 to 6 are shown separately in the above embodiments, this disclosure is not limited thereto. For example, the first information may include all the information shown in Tables 1 to 6 as well as additional information described with reference to Tables 1 to 6, and the first information may include corresponding fields for various different time slots as needed, while other fields that do not need to be included may be empty or reserved.
[0092] Figure 5 This is a flowchart illustrating another communication method according to an example embodiment. Figure 5 The communication method shown can be applied to WLAN-aware responders. For example, a WLAN-aware responder could be a STA.
[0093] Reference Figure 5 In step 510, a sensing measurement establishment message frame may be received. According to embodiments of this disclosure, the sensing measurement establishment message frame may include first information associated with a time slot for WLAN sensing measurement feedback, wherein the time slot may represent the time interval for feeding back sensing measurement results.
[0094] According to embodiments of this disclosure, the first information may include corresponding information based on the time slot representing different time intervals.
[0095] According to embodiments of this disclosure, the first information may include one of the following:
[0096] Information used to identify feedback for each measurement event;
[0097] Information used to identify feedback at every specific number of perceived measurement events;
[0098] Information used to identify feedback at intervals of a specific number of bursts;
[0099] Information used to identify feedback generated at every certain number of sensing measurements.
[0100] The embodiments described above in conjunction with Tables 1 to 6 can be applied here, and for the sake of brevity, repeated descriptions are omitted here.
[0101] According to embodiments of this disclosure, the first information may further include Time Synchronization Function (TSF) information.
[0102] According to embodiments of this disclosure, the sensing measurement establishment message frame may further include second information for identifying the mode of WLAN sensing measurement feedback, wherein the mode may include an immediate feedback mode or a delayed feedback mode.
[0103] According to embodiments of this disclosure, in the case of a second information identification timely feedback method, the first information may include information for identifying feedback for each measurement event.
[0104] According to embodiments of this disclosure, in the case of a second information identification delay feedback method, the first information may include one of the following:
[0105] Information used to identify feedback at every specific number of perceived measurement events;
[0106] Information used to identify feedback at intervals of a specific number of bursts;
[0107] Information used to identify feedback generated at every certain number of sensing measurements.
[0108] In step 520, WLAN sensing measurement feedback can be performed based on the sensing measurement establishment message frame. For example, the responder can determine the feedback time slot and feedback method based on the first information in the measurement establishment message frame (or, based on the first and second information), and send the WLAN sensing measurement results (e.g., but not limited to, channel state information CSI) to the initiator based on the feedback time slot.

Figure 6 The communication device 600 may include a processing module 610 and a transceiver module 620. In one embodiment of this disclosure, Figure 6 The communication device 600 shown can be applied to an initiator (e.g., an AP); in another embodiment of this disclosure, Figure 6 The communication device 600 shown can be applied to a responder (e.g., a STA).
