Description

Technical Field

[0001] This application claims the priority of Chinese Patent Application No. 202111679651.4, titled "MEASUREMENT SETUP IDENTIFIER DETERMINING METHOD AND RELATED APPARATUS", filed with the China National Intellectual Property Administration on December 31, 2021, the entire content of which is incorporated herein by reference.

[0002] Technical Field This application relates to the field of wireless communication technology, and particularly to a method for determining a measurement setup identifier and related apparatuses.

Background Art

[0003] The widespread deployment of wireless fidelity (Wi-Fi) devices and the increasing sensing requirements have made sensing performed by widely available Wi-Fi devices a hot topic in current research. In everyday life, signals transmitted from Wi-Fi devices are typically only received after being reflected, diffracted, and scattered by various obstacles. As a result, the signal actually received is usually a superposition of multiple signals. Therefore, a radio signal can sense the physical environment through which it passes, and the surrounding environment can be inferred by analyzing the radio signal "modulated" by various obstacles, thereby deriving wireless local area network (WLAN) sensing technology. WLAN sensing is a technology with a wide range of applications. In WLAN sensing technology, widely deployed Wi-Fi devices can be used to sense the surrounding environment by transmitting specific data or communication channel probe frames, receive reflected signals or feedback information generated by peer devices in the wireless network, and then extract corresponding parameters in the received signal by using specific algorithms for analysis. This allows for the acquisition of information about the surrounding environment.

[0004] The sensing procedure defined in the 802.11bf standard primarily consists of five phases: sensing session setup, measurement setup, measurement instance, measurement setup termination, and sensing session termination. The measurement setup is mainly used by the sensing initiator and sensing responder to exchange and unify the parameters / features used in the sensing procedure. In the sensing procedure, the sensing initiator and sensing responder may exchange and integrate multiple groups of parameters / features used in the sensing procedure. Therefore, for clear identification, a method is proposed to label the measurement setups to distinguish between different groups of parameters / features used in the sensing procedure.

[0005] The 802.11bf protocol currently does not support sensing between two non-access point stations (non-AP STAs), therefore there are special scenarios for sensing procedures. Specifically, a station (STA) requires an access point (AP) to help complete measurements with another sensing responder. For ease of explanation, this special scenario will be referred to as a proxy sensing scenario in this specification. Thus, how to identify a measurement setup in a proxy sensing scenario is a matter worth considering. [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] Embodiments of this application provide a method for determining a measurement setup identifier and related devices to solve the problem of setting a measurement setup identifier in a proxy sensing scenario, and as a result, the set of measurement setup identifiers in a proxy sensing scenario can be distinguished from the set of measurement setup identifiers in a common sensing scenario (or a non-proxy sensing scenario). [Means for solving the problem]

[0007] The present application will be described below from various perspectives. It should be understood that the following implementations and advantageous effects of different embodiments are mutually referenced.

[0008] According to a first aspect, the present application provides a method for determining a measurement setup identifier. The method further includes a proxy sensing initiator (AP) acquiring first measurement setup parameters and transmitting first information to a sensing responder (STA3), wherein the first information includes first measurement setup parameters and a first measurement setup identifier. The first measurement setup parameters include parameters used by the proxy sensing initiator (AP) and the sensing responder (STA3) in a proxy sensing procedure. The first measurement setup identifier identifies the first measurement setup parameters. The first measurement setup identifier is different from a measurement setup identifier used by the proxy sensing initiator (AP).

[0009] Optionally, before the proxy sensing initiator (AP) obtains the first measurement setup parameters, the requesting STA (STA1) may request the AP to perform sensing measurements as a proxy for the requesting STA.

[0010] Optionally, after receiving the first information, the first sensing responder (STA3) can establish an association relationship between the first measurement setup parameters and the first measurement setup identifier, and in subsequent sensing measurement procedures, it can uniquely index the first measurement setup parameters by using the first measurement setup identifier.

[0011] In this application, the measurement setup identifier used by the proxy sensing initiator (AP) includes a measurement setup identifier used by the proxy sensing initiator (AP) in a sensing procedure (here, a non-proxy sensing procedure) and a measurement setup identifier used by the proxy sensing initiator (AP) in a proxy sensing procedure.

[0012] The measurement setup parameters in this application may include parameters such as the role of the proxy sensing initiator, the role of the sensing responder, bandwidth, and measurement feedback type.

[0013] This solution addresses the issue of setting measurement setup identifiers in proxy sensing scenarios by restricting the measurement setup ID set in the proxy sensing procedure to not belong to an existing measurement setup ID set in the AP. In addition, the measurement setup identifier set in the proxy sensing scenario is distinguished from the measurement setup identifier set in the common sensing scenario (or non-proxy sensing scenario), thereby avoiding confusion and preventing impact on subsequent sensing measurement procedures.

[0014] In relation to the first aspect, in possible implementations, the acquisition of a first measurement setup parameter by a proxy sensing initiator (AP) includes the reception of second information transmitted by a requesting station (STA), the second information including a second measurement setup parameter, which includes all or some of the parameters used by the proxy sensing initiator (AP) and the sensing responder (STA3) in the proxy sensing procedure. The proxy sensing initiator (AP) determines the first measurement setup parameter based on the second measurement setup parameter. In other words, the proxy sensing initiator (AP) and the requesting STA may determine the first measurement setup parameter through negotiation.

[0015] In relation to the first aspect, in a possible implementation, the acquisition of the first measurement setup parameters by the proxy sensing initiator (AP) includes the receiving of second information transmitted by the requesting STA, where the second information includes the first measurement setup parameters. In other words, the requesting STA directly notifies the proxy sensing initiator (AP) of the relevant parameters of the measurement setup it wishes to establish (i.e., the first measurement setup parameters), and the proxy sensing initiator (AP) does not need to negotiate with the requesting STA about the relevant parameters because it cannot change them.

[0016] Optionally, the second information further includes a second measurement setup identifier. The second measurement setup identifier may identify the first measurement setup parameters. When the second information further includes a second measurement setup identifier, a mapping relationship may exist within the proxy sensing initiator (AP), for example, the second measurement setup identifier corresponds to the first measurement setup identifier. Thus, when the requesting STA exchanges information related to the first measurement setup identifier with the proxy sensing initiator (AP), the proxy sensing initiator (AP) and the sensing responder (STA3) use the second measurement setup identifier to indicate the relevant information.

[0017] Optionally, if the second measurement setup identifier is not a measurement setup identifier used by the proxy sensing initiator (AP), the proxy sensing initiator (AP) uses the second measurement setup identifier as the first measurement setup identifier. In other words, if the second measurement setup identifier is not a measurement setup identifier used by the proxy sensing initiator (AP), the first measurement setup identifier is the same as the second measurement setup identifier.

[0018] According to the first aspect, in a possible implementation, after the proxy sensing initiator (AP) transmits first information to the sensing responder (STA3), the method further includes the proxy sensing initiator (AP) transmitting third information to the sensing responder (STA3), the third information including a first measurement setup identifier.

[0019] Optionally, in addition to carrying the first measurement setup identifier, the third information further carries some of the parameters in the first measurement setup parameters, such as bandwidth.

[0020] According to a second aspect, the present application provides a communication device. The communication device may be a proxy sensing initiator (AP) or a chip within a proxy sensing initiator (AP), such as a Wi-Fi chip. The communication device includes: an acquisition module configured to acquire first measurement setup parameters, wherein the first measurement setup parameters include parameters used by the proxy sensing initiator (AP) and sensing responder (STA3) in a proxy sensing procedure; and a transceiver module configured to transmit first information to a sensing responder, wherein the first information includes the first measurement setup parameters and a first measurement setup identifier, wherein the first measurement setup identifier identifies the first measurement setup parameters, and the first measurement setup identifier is different from a measurement setup identifier used by the proxy sensing initiator (AP).

[0021] In relation to the second aspect, in a possible implementation, the acquisition module includes a receiving unit and a determination unit. The receiving unit is configured to receive second information transmitted by the requesting station STA, the second information including second measurement setup parameters, the second measurement setup parameters including all or some of the parameters used by the proxy sensing initiator (AP) and sensing responder (STA3) in the proxy sensing procedure. The determination unit is configured to determine first measurement setup parameters based on the second measurement setup parameters.

[0022] In relation to the second aspect, in a possible implementation, a receiving unit within the acquisition module is configured to receive second information transmitted by the requesting STA, the second information including first measurement setup parameters.

[0023] Optionally, the second information further includes a second measurement setup identifier. The second measurement setup identifier corresponds to the first measurement setup identifier.

[0024] Optionally, when the second measurement setup identifier is not the measurement setup identifier used by the proxy sensing initiator (AP), the first measurement setup identifier is the same as the second measurement setup identifier.

[0025] In connection with the second aspect, in a possible implementation, the measurement setup identifier used by the proxy sensing initiator (AP) includes the measurement setup identifier used by the proxy sensing initiator (AP) in a sensing procedure (here, a non-proxy sensing procedure) and the measurement setup identifier used by the proxy sensing initiator (AP) in a proxy sensing procedure.

[0026] In connection with the second aspect, in a possible implementation, the transceiver module is further configured to transmit third information to the sensing responder (STA3), where the third information includes the first measurement setup identifier.

[0027] According to a third aspect, the present application provides a method for determining a measurement setup identifier. The method further includes an access point (AP) as a proxy sensing initiator obtaining first measurement setup parameters and transmitting first information to a sensing responder (STA3), where the first information includes the first measurement setup parameters and a first measurement setup identifier. The first measurement setup parameters include the proxy sensing initiator (AP) and the sensing responder (STA3) in a proxy sensing procedure. The first measurement setup identifier identifies the first measurement setup parameters. If a third measurement setup identifier that identifies the same measurement setup parameters as the first measurement setup parameters exists within a first identifier set, the first measurement setup identifier is the third measurement setup identifier, or the first measurement setup identifier does not belong to the first identifier set, or if no measurement setup identifier that identifies the same measurement setup parameters as the first measurement setup parameters exists within the first identifier set, the first measurement setup identifier does not belong to the first identifier set. The first identifier set includes measurement setup identifiers used by the proxy sensing initiator.

[0028] Optionally, before the access point (AP) as a proxy sensing initiator obtains the first measurement setup parameters, a requesting station (STA1) requests the AP to perform a sensing measurement as a proxy for the requesting station.

[0029] Optionally, after receiving the first information, the sensing responder (STA3) can uniquely index the first measurement setup parameters by using the first measurement setup identifier in subsequent sensing measurement procedures in order to establish an association relationship between the first measurement setup parameters and the first measurement setup identifier.

[0030] In this application, the measurement setup identifier used by the proxy sensing initiator (AP) includes a measurement setup identifier used by the proxy sensing initiator (AP) in a sensing procedure (here, a non-proxy sensing procedure) and a measurement setup identifier used by the proxy sensing initiator (AP) in a proxy sensing procedure.

[0031] The measurement setup parameters in this application may include parameters such as the role of the proxy sensing initiator, the role of the sensing responder, bandwidth, and measurement feedback type.

[0032] In this solution, when an AP (Proxy Sensing Initiator) acting as a proxy identifies a measurement setup in the proxy sensing procedure, whether to use an ID from an existing set of measurement setup IDs in the AP is determined by whether the first measurement setup parameter is the same as the parameter corresponding to the measurement setup ID in the existing set of measurement setup IDs (i.e., the first identifier set) in the proxy AP (Proxy Sensing Initiator). In this way, the problem of setting measurement setup identifiers in proxy sensing scenarios is solved, and measurement setup identifiers in different scenarios can be distinguished, thereby avoiding confusion and saving ID resources.

[0033] In relation to the third aspect, in a possible implementation, the proxy sensing initiator (AP) obtaining the first measurement setup parameters includes the proxy sensing initiator (AP) receiving second information transmitted by the requesting STA, the second information including the second measurement setup parameters, which include all or some of the parameters used by the proxy sensing initiator (AP) and the sensing responder (STA3) in the proxy sensing procedure. The proxy sensing initiator (AP) determines the first measurement setup parameters based on the second measurement setup parameters. In other words, the proxy sensing initiator (AP) and the requesting STA may determine the first measurement setup parameters through negotiation.

[0034] In relation to the third aspect, in a possible implementation, the acquisition of the first measurement setup parameters by the Proxy Sensing Initiator (AP) includes the reception of second information sent by the Requesting STA, the second information including the first measurement setup parameters. In other words, the Requesting STA directly notifies the Proxy Sensing Initiator (AP) of the relevant parameters of the measurement setup it wishes to establish (i.e., the first measurement setup parameters), and the Proxy Sensing Initiator (AP) does not need to negotiate the relevant parameters with the Requesting STA because the Proxy Sensing Initiator (AP) cannot change the relevant parameters.

[0035] Optionally, the second information may further include a second measurement setup identifier. The second measurement setup identifier may identify the first measurement setup parameters. When the second information further includes a second measurement setup identifier, a mapping relationship may exist within the proxy sensing initiator (AP), for example, the second measurement setup identifier may correspond to the first measurement setup identifier. Thus, when a requesting STA exchanges information related to the first measurement setup identifier with the proxy sensing initiator (AP), the proxy sensing initiator (AP) and the sensing responder (STA3) use the second measurement setup identifier to indicate the relevant information.

[0036] In relation to a third aspect, in a possible implementation, after the proxy sensing initiator (AP) transmits first information to the sensing responder (STA3), the method may further include the proxy sensing initiator (AP) transmitting third information to the sensing responder (STA3), the third information including a first measurement setup identifier.

[0037] Optionally, in addition to carrying the first measurement setup identifier, the third information may further carry some of the parameters among the first measurement setup parameters, such as bandwidth.

[0038] According to a fourth aspect, the present application provides a communication device. The communication device may be a proxy sensing initiator (AP) or a chip within a proxy sensing initiator (AP), such as a Wi-Fi chip. The communication device includes: an acquisition module configured to acquire a first measurement setup parameter, wherein the first measurement setup parameter includes a parameter used by a proxy sensing initiator and a sensing responder in a proxy sensing procedure; and a transceiver module configured to transmit first information to a sensing responder, wherein the first information includes the first measurement setup parameter and a first measurement setup identifier, wherein the first measurement setup identifier identifies the first measurement setup parameter. If a third measurement setup identifier that identifies the same measurement setup parameter as the first measurement setup parameter exists in the first identifier set, then the first measurement setup identifier is either the third measurement setup identifier, or the first measurement setup identifier does not belong to the first identifier set, or if no measurement setup identifier that identifies the same measurement setup parameter as the first measurement setup parameter exists in the first identifier set, then the first measurement setup identifier does not belong to the first identifier set. The first identifier set includes measurement setup identifiers used by the proxy sensing initiator.

[0039] In relation to the fourth aspect, in a possible implementation, the acquisition module includes a receiving unit and a determination unit.

The determination unit is configured to determine first measurement setup parameters based on the second measurement setup parameters.

[0040] In relation to the fourth aspect, in a possible implementation, a receiving unit within the acquisition module is configured to receive second information transmitted by the requesting STA, the second information including first measurement setup parameters.

[0041] Optionally, the second information further includes a second measurement setup identifier. The second measurement setup identifier corresponds to the first measurement setup identifier.

[0046] The measurement setup parameters in this application may include parameters such as the role of the proxy sensing initiator, the role of the sensing responder, bandwidth, and measurement feedback type.

[0047] In this solution, when the proxy sensing procedure transmits the measurement setup ID, the proxy sensing initiator (AP) carries information to identify the requesting STA and / or information indicating that the measurement setup to be established belongs to the proxy sensing procedure, helping the sensing responder (STA3) identify different measurement setups. From another perspective, this solves the problem of setting measurement setup identifiers in proxy sensing scenarios, thereby avoiding confusion.

[0048] In relation to the fifth aspect, in possible implementations, the information for identifying the requesting STA includes one or more of the following: the identifier of the requesting STA, part or all of the medium access control (MAC) address of the requesting STA, and the virtual number of the requesting STA. The identifier of the requesting STA is part or all of the association identifier of the requesting STA, or part or all of the non-associated station identifier of the requesting STA. The virtual number of the requesting STA may be set by the AP (Proxy Sensing Initiator). Information indicating that the measurement setup requested to be established using the first information belongs to a proxy sensing procedure may be 1 bit. When the bit is set to 1, this indicates that the measurement setup requested to be established using the first information belongs to a proxy sensing procedure. When the bit is set to 0, this indicates that the measurement setup requested to be established using the first information does not belong to a proxy sensing procedure or is reserved.

[0094] The following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings.

[0095] In this description, unless otherwise specified, " / " means "or". For example, "and / or" simply describes the association relationship between the related objects, indicating that three relationships may exist. For example, A and / or B may represent the following three cases: that only A exists, that both A and B exist, or that only B exists. In addition, "at least one" means one or more, and "multiple" means two or more. "At least one of the following items (parts)" or a similar expression refers to any combination of these items, including a single item (part) or any combination of multiple items (parts). For example, at least one of a, b, or c may represent a, b, c, a and b, a and c, b and c, or a, b and c, where a, b, and c may each be singular or plural.

[0096] In the description of this application, terms such as "first" and "second" do not limit the quantity or order of execution, nor do terms such as "first" and "second" indicate a clear difference.

[0097] In this application, the terms “Examples” or “For example” are used to indicate that examples, illustrations, or descriptions are being provided. Any embodiment or design scheme described in this application as “Examples,” “Like,” or “For example” should not be described as being more preferable or having more advantages than another embodiment or design scheme. More precisely, the use of terms such as “Examples,” “Like,” and “For example” is intended to specifically present the relevant concepts.

[0098] In this application, elements expressed in the singular form are intended to represent "one or more," but not "one or only one" unless otherwise specified.

[0099] In the embodiments of this application, it should be understood that "B corresponding to A" indicates that B is associated with A and that B can be determined based on A. However, it should be further understood that determining B based on A does not mean that B is determined solely based on A. B may alternatively be determined based on A and / or other information.

[0100] The following provides a brief explanation of some of the concepts, terms, or nouns related to this application.

[0101] 1. Four roles in the sensing procedure

[0102] A sensing initiator is the station that initiates the sensing procedure (the STA that initiates the WLAN sensing procedure).

[0103] A sensing responder is a station that participates in a sensing procedure initiated by a sensing initiator (an STA that participates in a WLAN sensing procedure initiated by a sensing initiator).

[0104] A sensing transmitter is a station (STA) that transmits physical layer (PHY) protocol data units (PPDUs) used for sensing measurements in a sensing procedure.

[0105] A sensing receiver is a station (STA) that receives the PPDU transmitted by the sensing transmitter and performs sensing measurements in the sensing procedure.

[0106] 2. Sensing procedure

[0107] The sensing procedure mainly consists of five phases:

[0108] Sensing session setup: Sensing session setup is the phase in which a sensing session is established between stations. During this phase, several relevant parameters can be exchanged. It should be understood that a sensing session is a protocol achieved by a sensing initiator and a sensing responder. While one sensing initiator can maintain sensing sessions with multiple sensing responders, multiple sensing sessions still need to be set up one by one. For example, in orthogonal frequency division multiple access (OFDMA) or multi-user multiple-input multiple-output (MU-MIMO) schemes, multiple sensing sessions can be established simultaneously.

[0109] Measurement setup: Measurement setup is used by sensing initiators and sensing responders to swap and integrate several parameters or features that need to be used in the sensing procedure, such as the roles of the sensing initiator and sensing responder (e.g., whether the sensing initiator is a sensing transmitter or sensing receiver during sensing measurement, and whether the sensing responder is a sensing transmitter or sensing receiver during sensing measurement), and the measurement feedback type.

[0110] Measurement Instance: Sensing measurements are performed within a measurement instance. A single measurement instance can accommodate multiple sensing responders.

[0111] Measurement setup termination: Measurement setup termination is used to end the measurement setup corresponding to a sensing responder. The sensing responder is no longer bound to the corresponding measurement setup, although it may still be in a sensing session.

[0112] Sensing session termination: Sensing session termination indicates that the sensing session has ended and the station will no longer participate in procedures such as sensing measurement.

[0113] To more clearly explain how the above sensing procedure works, please refer to the attached diagrams below.

[0114] Figure 1 is a schematic diagram of a sensing procedure according to an embodiment of the present application. As shown in Figure 1, the sensing procedure shown in Figure 1 includes 16 phases. The 16 phases are illustrative and may be temporally discontinuous. For example, there may be another phase between phase 6 and phase 7, but this is not shown in Figure 1. Figure 1 is merely an example, and it should be understood that in actual applications, there may be more or fewer phases in the sensing procedure than those shown in Figure 1. Phase 1 indicates that a station with a medium access control (MAC) address of A and an association identifier (AID) of 1 participates in a sensing session, i.e., the sensing session setup procedure. Phase 2 indicates that the relevant parameters that need to be used in the sensing procedure are configured for the station, i.e., the sensing measurement setup. In Phase 2, it should be understood that a method of labeling sensing measurement setups, i.e., measurement setup ID=1, is used to clearly identify different measurement setups. In this application, the measurement setup identifier (measurement setup ID) can be understood as identifying a group of parameters or features that need to be used in a sensing procedure for exchange and unification between a sensing initiator and a sensing responder. Phase 3 is the measurement instance. One measurement instance corresponds to one sensing measurement setup identifier (measurement setup ID), in other words, one measurement instance is bound to a group of parameters or features (the group of parameters or features is used for sensing measurement). Thus, a station with AID=1 can perform a measurement in a measurement instance. Each measurement instance also has a corresponding label. In summary, phases 1, 2, and 3 are used to bring a station into a sensing session and initiate measurement and feedback.

[0115] Phase 4 indicates that another measurement instance occurs. Here, to distinguish this measurement instance from the previous one, the identifier for the measurement instance is, in this case, +1, i.e., measurement instance 21, which corresponds to measurement setup 1. Phases 5 and 6 are similar to phases 2 and 3 and constitute another group of relevant parameters that need to be used in the sensing procedure for the station with AID=1, specifically, they constitute measurement setup 2 and are used to perform measurement and feedback.

[0116] Phases 7, 8, and 9 are similar to phases 1, 2, and 3. Stations with an Unassociated Station Identifier (UID) equal to 2 join the sensing session, another group of relevant parameters that need to be used in the sensing procedure are configured for stations with UID=2 (measurement setup 2 is assigned to stations with UID=2), and then a measurement instance occurs after measurement setup 2.

[0117] Phase 10 indicates that the station with AID=1 is unbound from measurement setup 2 (in other words, the station with AID=1 is unbound from another group of associated parameters). In this case, the station with AID=1 remains bound to measurement setup 1. Phases 11 and 12 indicate that the parameters corresponding to measurement setup ID=1 are configured for the station with UID=2.

[0118] Phase 13 indicates that the station with AID=1 is ending its sensing session.

[0119] Phases 14, 15, and 16 are similar to phases 1, 2, and 3, showing that the station with AID=3 participates in the sensing session and is bound to measurement setup ID=2. Therefore, in phase 16, we can see that the station with AID=3 and the station with UID=2 can simultaneously participate in sensing measurement and feedback in the measurement instance.

[0120] The four phases—sensing session setup, measurement setup, measurement setup completion, and sensing session completion—are all one-to-one setup phases. Let's take the sensing session setup phase as an example. One sensing session setup corresponds to one sensing initiator and one sensing responder. Of course, the sensing initiator may alternatively set up sensing sessions with multiple stations simultaneously, for example, in OFDMA or MU-MIMO format, but multiple sensing sessions will be set up simultaneously.

[0121] The measurement instance phase is different from the four phases described above. A single measurement instance can have one-to-many cases, such as one-to-many announcements or triggers.

[0122] Measurement instances can be classified into trigger-based sensing measurement instances (TB sensing measurement instances) and non-trigger-based sensing measurement instances (non-TB sensing measurement instances).

[0123] A trigger-based sensing measurement instance includes the following phases: a polling phase, a null data packet announcement (NDPA) sounding phase, a trigger frame (TF) sounding phase, and a reporting phase. In the NDP announcement sounding phase, a sensing initiator may use an NDPA (NDP announcement) to notify a corresponding station that the sensing initiator will soon transmit an NDP. The NDPA is used to notify stations that need to listen for NDP and other configuration information, and the corresponding station can then measure the subsequently transmitted NDP to learn channel information. In the trigger frame sounding phase, a sensing initiator may use a trigger frame to trigger a peer end to transmit an NDP and perform sensing by measuring the transmitted NDP. In addition, the function of the polling phase is to ensure that polled stations can participate in the measurement and feedback in the current measurement instance.

[0124] For non-trigger-based sensing measurement instances, peer-end NDP transmission can be introduced by transmitting an NDPA or by other means.

[0125] 3. Setting the Measurement Setup Identifier (Measurement Setup ID) in the Sensing Procedure

[0126] In this application, a measurement setup identifier (measurement setup ID) may identify a group of parameters or features that need to be used in a sensing procedure for exchange and unification between a sensing initiator and a sensing responder.

[0127] The measurement setup ID between two devices can be set by the sensing initiator. FIG. 2 is a schematic diagram for setting the measurement setup identifier according to an embodiment of the present application. As shown in FIG. 2, FIG. 2 shows the setting of the measurement setup identifier when the sensing initiators are different. Use the second dashed box and the fourth dashed box from left to right in FIG. 2 as examples. In the second dashed box from left to right in FIG. 2, the AP is used as the sensing initiator. In the fourth dashed box from left to right in FIG. 2, STA1 is used as the sensing initiator. The measurement setup ID between the AP and STA1 may both be 1 even if the parameters or features identified by the measurement setup ID do not match. This is because the address field of the PPDU transmitted by the sensing initiator carries the MAC address (MAC Addresses) of the sensing initiator, and the sensing responder can distinguish different measurement setups by identifying <MAC address of the sensing initiator, measurement setup ID>. Therefore, the same measurement setup ID is used between the AP and STA1, and the sensing responder can distinguish different measurement setups without conflict. Specifically, the sensing responder can distinguish the measurement setup between the AP and STA1 by using <MAC address of the AP, measurement setup ID = 1> and <MAC address of STA1, measurement setup ID = 1>.

[0128] It should be understood that there may be two ways to set up a session between the two devices shown in Figure 2. Let's take the session setup between AP and STA1 in Figure 2 as an example. The session setup between AP and STA1 may be a sensing session set up by using AP as the sensing initiator, or it may be a sensing session set up by using STA1 as the sensing initiator. In this case, the measurement setup, shown by the third dashed line from left to right in Figure 2, may be performed after the sensing session has been set up by using AP as the sensing initiator, or after the sensing session has been set up by using STA1 as the sensing initiator. In other words, in this embodiment of the present application, the specific method of session setup is not limited, and the sensing initiator in the session setup procedure does not necessarily have to be the same as the sensing initiator in the measurement setup procedure, and may be different.

[0129] Current protocols do not support sensing between two non-access point stations (non-AP STAs), so there are special scenarios for sensing procedures. Specifically, an STA wants an AP to help complete measurements with another sensing responder. For example, a device in a room wants the AP to help the device feed back channel state information (CSI) from devices connected to the AP in all rooms of the house. This special scenario is called a proxy sensing scenario.

[0130] To support this particular scenario in the sensing procedure (in other words, to support the proxy sensing scenario), we propose a proxy sensing procedure. Figure 3 is a schematic diagram of a proxy sensing scenario according to an embodiment of the present application. As shown in Figure 3, the proxy sensing scenario includes a requesting STA (STA1 in Figure 3), a proxy (AP in Figure 3) / proxy AP (proxy AP), and a sensing responder (STA2 and / or STA3 in Figure 3). Referring to the proxy sensing scenario shown in Figure 3, the proxy sensing procedure can be described as follows: The requesting STA (or Sensing by Proxy Requesting Station (SBP requesting STA), SBP = Sensing by Proxy) requests the AP to act as a proxy for the requesting STA and perform the measurement; the AP performs the sensing with the sensing responder (e.g., STA2 or STA3); the AP reports the sensing information to the requesting STA. A sensing procedure between the AP and the requesting STA may or may not exist. When a sensing procedure exists between the AP and the requesting STA, the requesting STA can also function as a sensing responder in that procedure.

[0131] In this application, the required STA may be understood as an initial sensing initiator, and the AP may be understood as a proxy sensing initiator (or simply referred to as "proxy").

[0132] In the proxy sensing scenario shown in FIG. 3, when the AP participates in non-proxy sensing (for example, the AP functions as a sensing initiator to perform sensing with STA3) and participates in proxy sensing (for example, the AP functions as a proxy for STA1 to perform sensing with STA3), since the MAC addresses of the sensing initiators carried in the PPDU transmitted by the AP are each the MAC address of the AP, if the measurement setup is identified only by using <MAC address, measurement setup ID>, the sensing responder cannot distinguish different measurement setups corresponding to the same measurement setup ID. Therefore, the parameters / characteristics determined by the measurement setup ID cannot be determined, which affects the subsequent sensing measurement procedure. In other words, the method of setting the measurement setup identifier in the non-proxy sensing procedure is not applicable to the proxy sensing scenario. Therefore, how to set the measurement setup identifier in the proxy sensing scenario is an urgent problem to be solved.

[0133] Therefore, the embodiments of the present application solve the problem of setting a measurement setup identifier (measurement setup ID) in the proxy sensing scenario, thereby providing a measurement setup identifier determination method so that the measurement setup identifier set in the proxy sensing scenario can be distinguished from the measurement setup identifier set in the non-proxy sensing scenario. In other words, according to the measurement setup identifier determination method provided in the embodiments of the present application, the sensing responder can distinguish different measurement setups based on the measurement setup identifier. In other words, the sensing responder can uniquely determine the group of parameters / characteristics used for the sensing measurement by using the measurement setup identifier.

[0134] The technical solution provided in this application may be applied to the proxy sensing scenario shown in Figure 3. The apparatus for implementing the method of this application may be an AP or STA in a WLAN, or a chip or processing system located within the AP or STA.

[0135] An access point (e.g., the AP in Figure 3) is a device having wireless communication capabilities, supporting communication using the WLAN protocol, and having the ability to communicate with other devices in the WLAN network (e.g., a station or another access point), although it may, of course, have the ability to communicate with other devices as well. In a WLAN system, an access point is sometimes called an access point station (AP STA). The device having wireless communication capabilities may be an overall device, or a chip or processing system mounted on an overall device. A device on which a chip or processing system is mounted may implement the methods and functions of the embodiments of this application under the control of the chip or processing system. The AP in the embodiments of this application is a device that provides services to an STA and may support the 802.11 series protocol. For example, the AP may be a communication entity, such as a communication server, router, switch, or bridge. The AP may include various forms of macro base stations, micro base stations, relay stations, etc. Of course, the AP may alternatively be a chip or processing system in various forms of these devices to implement the methods and functions of the embodiments of this application.

[0136] A station (for example, STA1, STA2, or STA3 in Figure 3) is a device having wireless communication capabilities, supporting communication using the WLAN protocol, and having the ability to communicate with other stations or access points within the WLAN network. In a WLAN system, a station is sometimes referred to as a non-access point station (non-AP STA). For example, an STA is any user communication device that enables a user to communicate with an AP and further with the WLAN. A device having wireless communication capabilities may be an overall device, or a chip or processing system mounted on an overall device. A device on which a chip or processing system is mounted may implement the methods and functions of the embodiments of this application under the control of the chip or processing system. For example, an STA may be an internet-connected user device, such as a tablet computer, desktop computer, laptop computer, notebook computer, ultra-mobile personal computer (UMPC), handheld computer, netbook, personal digital assistant (PDA), or mobile phone. Alternatively, STA may be an Internet of Things node in the Internet of Things, an in-vehicle communication device in the Internet of Vehicles, an entertainment device, a game device or system, a global positioning system device, etc. Alternatively, STA may be a chip and processing system within the aforementioned terminal.

[0137] WLAN systems can provide high-speed and low-latency transmission. With the continuous evolution of WLAN application scenarios, WLAN systems are applicable to a wider range of scenarios and industries, such as the Internet of Things industry, the Internet of Automotive industry, the banking industry, corporate offices, stadiums, exhibition halls, concert halls, hotel rooms, dormitories, wards, classrooms, supermarkets, squares, streets, manufacturing workshops, and warehouses. Of course, devices that support WLAN communication (e.g., access points or stations) may include sensor nodes in smart cities (e.g., smart water meters, smart electricity meters, or smart air detection nodes), smart devices in smart homes (e.g., smart cameras, projectors, displays, televisions, stereos, refrigerators, or washing machines), nodes in the Internet of Things, entertainment terminals (e.g., augmented reality (AR), virtual reality (VR), or other wearable devices), smart devices in smart offices (e.g., printers, projectors, speakers, or stereos), internet access for vehicle devices in the Vehicle Internet, infrastructure in everyday life scenarios (e.g., vending machines, self-service navigation stations in supermarkets, self-service cash register devices, or self-service ordering machines), devices in large-scale sports or music venues, etc. The specific forms of STA and AP are not limited to the embodiments of this application and are merely examples for illustrative purposes.

[0138] It should be understood that the 802.11 standard focuses on the physical layer (PHY) and medium access control (MAC) layers. For an example, see Figure 4a. Figure 4a is a schematic diagram of the structure of an access point according to an embodiment of the present application. The AP may be multi-antenna / multi-radio frequency or single-antenna / single-radio frequency. The antenna / radio frequency is used to send and receive data packets (in this specification, data packets are also called physical layer protocol data units (PHY protocol data units, PPDUs)). In one implementation, the antenna or radio frequency portion of the AP may be separated from the main body of the AP, i.e., located remotely. In Figure 4a, the AP may include physical layer processing circuitry and medium access control processing circuitry. The physical layer processing circuitry may be configured to process physical layer signals, and the MAC layer processing circuitry may be configured to process MAC layer signals. For another example, see Figure 4b. Figure 4b is a schematic diagram of the structure of a station according to an embodiment of the present application. Figure 4b is a schematic diagram of the structure of a single-antenna / single-radio frequency STA. In a real-world scenario, the STA may be multi-antenna / multi-radio frequency, and may be a device with more than two antennas. The antennas / radio frequencies are used to send and receive data packets. In one implementation, the antenna or radio frequency portion of the STA may be separated from the main body of the STA, i.e., located remotely. In Figure 4b, the STA may include a PHY processing circuit and a MAC processing circuit. The physical layer processing circuit may be configured to process physical layer signals, and the MAC layer processing circuit may be configured to process MAC layer signals.

[0139] The technical solutions provided in this application will be described in detail below with reference to further attached drawings.

[0140] In this application, unless otherwise specified, identical or similar parts of embodiments or implementations should be referenced to one another. In the embodiments and implementations / implementation methods of the embodiments of this application, unless otherwise specified or unless a logical contradiction arises, terminology and / or descriptions are consistent and may be referenced to one another between different embodiments and between implementations / implementation methods of the embodiments. Technical features of different embodiments and implementations / implementation methods of the embodiments may be combined to form new embodiments, implementations, or implementation methods based on their internal logical relationships. The following implementations of this application are not intended to limit the scope of protection of this application.

[0141] Optionally, the proxy sensing initiator in this application may be the AP shown in Figure 3, the requesting STA in this application may be STA1 shown in Figure 3, and the sensing responder in this application may be STA3 or STA2 shown in Figure 3. In this application, the proxy sensing initiator, requesting STA and sensing responder all support a WLAN sensing protocol such as 802.11bf or the next-generation protocol of 802.11bf.

[0142] Embodiment 1 Figure 5 is a schematic flowchart of a measurement setup identifier determination method according to an embodiment of the present application. The measurement setup identifier determination method can be applied to the proxy sensing scenario shown in Figure 3. This method primarily explains how the measurement setup ID set in the proxy sensing procedure is distinguished from the existing measurement setup ID set in the AP. As shown in Figure 5, the measurement setup identifier determination method includes, but is not limited to, the following steps.

[0143] S101: The proxy sensing initiator (AP) acquires first measurement setup parameters, which include parameters used by the proxy sensing initiator and sensing responder in the proxy sensing procedure.

[0144] In one implementation, a requesting STA (e.g., STA1 in Figure 3) may request an AP to act as a proxy for the requesting STA and perform sensing measurements. The requesting STA may further send to the AP (Proxy Sensing Initiator) relevant parameters of the measurement setup that the requesting STA wishes to establish (referred to as the second measurement setup parameters). In this application, the measurement setup parameters are parameters used for sensing measurements, such as the role of the proxy sensing initiator, the role of the sensing responder, bandwidth, and measurement feedback type. After receiving the second measurement setup parameters, the AP (Proxy Sensing Initiator) may negotiate with the requesting STA to determine the parameters (i.e., the first measurement setup parameters) that will ultimately be used by the proxy sensing initiator (AP) and the sensing responder (e.g., STA3 in Figure 3) in the proxy sensing procedure. For example, after receiving the second measurement setup parameter, the AP (Proxy Sensing Initiator) determines the third measurement setup parameter based on the second measurement setup parameter and sends the determined third measurement setup parameter to the requesting STA. If the requesting STA agrees to the third measurement setup parameter, the requesting STA sends consent information to the AP (Proxy Sensing Initiator). After receiving the consent information, the AP (Proxy Sensing Initiator) uses the third measurement setup parameter as the first measurement setup parameter. If the requesting STA does not agree to the third measurement setup parameter, the requesting STA may send a new measurement setup parameter (the new measurement setup parameter is different from the second and third measurement setup parameters) to the AP (Proxy Sensing Initiator). After receiving the new measurement setup parameter, if the AP (Proxy Sensing Initiator) agrees to use the new measurement setup parameter, the AP (Proxy Sensing Initiator) uses the new measurement setup parameter as the first measurement setup parameter.If the AP (Proxy Sensing Initiator) does not agree to use the new measurement setup parameters, the AP and the requesting STA may continue negotiating until an agreement is reached.

[0145] The second measurement setup parameters include all or some of the parameters used by the proxy sensing initiator (AP) and sensing responder (e.g., STA3) in the proxy sensing procedure. For example, the second measurement setup parameters include parameters such as the role of the proxy sensing initiator, the role of the sensing responder, bandwidth, and measurement feedback type. If the second measurement setup parameters include some of the parameters used by the proxy sensing initiator and sensing responder in the proxy sensing procedure, the AP may negotiate the remaining parameters with the requesting STA, or it may negotiate all of the parameters with the requesting STA.

[0146] Optionally, the second measurement setup parameters may be carried in a request message sent to the AP by the requesting STA (STA1), or in a separate information / frame. This is not limited to this embodiment of the present application.

[0147] Optionally, when a requesting STA sends the relevant parameters of the measurement setup it wishes to establish to the AP (Proxy Sensing Initiator) (i.e., the second measurement setup parameters), the requesting STA may also simultaneously send a measurement setup identifier (which is set by the requesting STA and is referred to as the second measurement setup identifier). In other words, the second measurement setup parameters and the second measurement setup identifier may be contained within a single piece of information / frame, for example, within the second piece of information. Of course, the second measurement setup parameters and the second measurement setup identifier may be carried within different pieces of information / frames. The second measurement setup identifier may identify the first measurement setup parameters determined by the AP (Proxy Sensing Initiator) through negotiation with the requesting STA. It should be understood that, before the AP (Proxy Sensing Initiator) negotiates with the requesting STA to determine the first measurement setup parameters, or during the negotiation process between the AP and the requesting STA, the second measurement setup identifier alternatively identifies the second measurement setup parameters (i.e., the relevant parameters of the measurement setup that the requesting STA wishes to establish and that are sent to the AP by the STA) and the measurement setup parameters in the negotiation process (such as the aforementioned third measurement setup parameters and the aforementioned new measurement setup parameters). When the AP negotiates with the requesting STA to determine the first measurement setup parameters, and thereafter, the requesting STA and the AP continue to use the second measurement setup identifier to identify the first measurement setup parameters that are ultimately determined through the negotiation.

[0148] Thus, when a requesting STA wants the AP to establish multiple measurement setups on its behalf, specifically when the requesting STA needs to feed back channel state information corresponding to multiple groups of measurement setup parameters to the AP, the requesting STA notifies the AP (Proxy Sensing Initiator) of a second measurement setup identifier. When the requesting STA feeds back channel state information in this way, the AP can distinguish the channel state information corresponding to different measurement setup parameters of the requesting STA based on the measurement setup identifier notified by the requesting STA, thereby preventing the requesting STA from confusing the received channel state information.

[0149] Please understand that if the requesting STA requests only one measurement setup from the AP (Proxy Sensing Initiator), the requesting STA may not need to set a second measurement setup identifier for the first measurement setup parameter. This is because all channel state information received by the requesting STA is channel state information corresponding to the first measurement setup parameter, thus avoiding confusion.

[0150] In another implementation, a requesting STA (e.g., STA1 in Figure 3) may request an AP to perform a sensing measurement acting as a proxy for the requesting STA. The requesting STA may further send second information to the AP (proxy sensing initiator), which includes parameters used by the proxy sensing initiator (AP) and sensing responder (e.g., STA3 in Figure 3) in the proxy sensing procedure. In other words, the second information includes the first measurement setup parameters. That is, the relevant parameters of the measurement setup that the requesting STA wants to establish and that are sent by the requesting STA to the AP (proxy sensing initiator) are the first measurement setup parameters. The AP (proxy sensing initiator) receives the first information and obtains the second measurement setup parameters. In other words, the requesting STA directly notifies the AP (Proxy Sensing Initiator) of the relevant parameters of the measurement setup it wishes to establish, and the AP (Proxy Sensing Initiator) does not need to negotiate with the requesting STA regarding the relevant parameters because it cannot change them. The first measurement setup parameters may include parameters such as the role of the proxy sensing initiator, the role of the sensing responder, bandwidth, and measurement feedback type.

[0151] Optionally, the second information may be carried within a request message sent to the AP by the requesting STA (STA1), or within a separate information / frame. This is not limited to this embodiment of the present application.

[0152] Optionally, when sending the first measurement setup parameters to the AP (Proxy Sensing Initiator), the requesting STA may also simultaneously send a measurement setup identifier (which is set by the requesting STA and is referred to as the second measurement setup identifier). In other words, the second information may further include the second measurement setup identifier. Of course, the second measurement setup identifier and the first measurement setup parameters may alternatively be placed in different information / frames. The second measurement setup identifier can identify the first measurement setup parameters. In other words, the requesting STA and the AP (Proxy Sensing Initiator) use the second measurement setup identifier to identify the first measurement setup parameters.

[0153] In yet another implementation, a requesting STA (e.g., STA1 in Figure 3) requests an AP to act as a proxy for the requesting STA and perform sensing measurements. After receiving the requesting STA, the AP (i.e., the proxy sensing initiator) may determine the parameters used by the AP (proxy sensing initiator) and the sensing responder (e.g., STA3 in Figure 3) in the proxy sensing procedure; in other words, it may determine the first measurement setup parameters. The first measurement setup parameters may include parameters such as the role of the proxy sensing initiator, the role of the sensing responder, bandwidth, and measurement feedback type.

[0154] Optionally, after determining the first measurement setup parameters, the AP (i.e., the proxy sensing initiator) may notify the requesting STA. After receiving the first measurement setup parameters, the requesting STA may further set a measurement setup identifier, i.e., a second measurement setup identifier, for the first measurement setup parameters and notify the AP (i.e., the proxy sensing initiator) of the second measurement setup identifier.

[0155] Optionally, when a requesting STA requests an AP to act as a proxy for the requesting STA and perform sensing measurements, a measurement setup identifier (denoted as the second measurement setup identifier) ​​may be carried. After receiving the request from the requesting STA, the AP (proxy sensing initiator) determines the first measurement setup parameters and notifies the requesting STA of both the first measurement setup parameters and / or the second measurement setup identifier. In other words, when a requesting STA requests an AP to act as a proxy for the requesting STA, it sets a measurement setup identifier (i.e., the second measurement setup identifier). In this case, the second measurement setup identifier either does not identify any parameters, or the parameters identified by the second measurement setup identifier are an empty set. When the requesting STA receives the first measurement setup parameters sent by the AP (proxy sensing initiator), or when the requesting STA receives the first measurement setup parameters and the second measurement setup identifier sent by the AP (proxy sensing initiator), the requesting STA may learn that the second measurement setup identifier identifies the first measurement setup parameters.

[0156] S102: The proxy sensing initiator (AP) transmits first information to the sensing responder (STA3), where the first information includes first measurement setup parameters and first measurement setup identifier, the first measurement setup identifier identifies the first measurement setup parameters, and the first measurement setup identifier is not the measurement setup identifier used by the proxy sensing initiator; in other words, the first measurement setup identifier is different from the measurement setup identifier used by the proxy sensing initiator.

[0157] Optionally, after obtaining the first measurement setup parameter, the AP (Proxy Sensing Initiator) may set a measurement setup identifier (referred to as the first measurement setup identifier) ​​for the first measurement setup parameter, and the measurement setup identifier identifies the first measurement setup parameter. The first measurement setup identifier is not the measurement setup identifier used by the AP (Proxy Sensing Initiator); in other words, the first measurement setup identifier is different from the measurement setup identifier used by the AP (Proxy Sensing Initiator). In other words, when identifying a measurement setup in a proxy sensing procedure, the AP acting as a proxy needs to reuse a measurement setup ID that is different from the existing measurement setup ID in the AP. The measurement setup identifier used by the AP (Proxy Sensing Initiator) may include the measurement setup identifier used by the AP (Proxy Sensing Initiator) in a sensing procedure (here, a non-proxy sensing procedure), and / or the measurement setup identifier used by the AP (Proxy Sensing Initiator) in a proxy sensing procedure. In other words, the existing measurement setup ID set in the AP includes established measurement setup IDs that have been set as initiators by the AP in proxy sensing procedures, and established measurement setup IDs that have been set as initiators by the AP in non-proxy sensing procedures.

[0158] Optionally, after setting a first measurement setup identifier for the first measurement setup parameter, the AP (Proxy Sensing Initiator) may send a single piece of information (referred to as the first information) containing the first measurement setup parameter and the first measurement setup identifier to the sensing responder (e.g., STA3 in Figure 3). In other words, the AP (Proxy Sensing Initiator) and the sensing responder (e.g., STA3) use the first measurement setup identifier to identify the first measurement setup parameter. After receiving the first information, the sensing responder (e.g., STA3) can uniquely index the first measurement setup parameter by using the first measurement setup identifier in subsequent sensing measurement procedures in order to establish an association relationship between the first measurement setup parameter and the first measurement setup identifier.

[0159] Optionally, if the requesting STA sets a second measurement setup identifier for a first measurement setup parameter and notifies the AP (Proxy Sensing Initiator), a mapping relationship may exist within the AP (Proxy Sensing Initiator). Specifically, the first measurement setup identifier set by the AP (Proxy Sensing Initiator) for the first measurement setup parameter corresponds to the second measurement setup identifier set by the requesting STA for the first measurement setup parameter. In any embodiment, the AP (Proxy Sensing Initiator) may alternatively notify the requesting STA and / or the sensing responder (e.g., STA3) of the mapping relationship between the first measurement setup identifier and the second measurement setup identifier. Correspondingly, the AP (Proxy Sensing Initiator) may alternatively notify the sensing responder (e.g., STA3) of the second measurement setup identifier, and / or the AP (Proxy Sensing Initiator) may further notify the requesting STA of the first measurement setup identifier.

[0160] It should be understood that both the first measurement setup identifier and the second measurement setup identifier identify the first measurement setup parameters. When the requesting STA exchanges information related to the first measurement setup identifier with the AP (Proxy Sensing Initiator), the AP (Proxy Sensing Initiator) and STA3 (Sensing Responder) use the second measurement setup identifier to indicate the relevant information.

[0161] If the second measurement setup identifier is not a measurement setup identifier used by the AP (Proxy Sensing Initiator), in other words, if the second measurement setup identifier is different from the measurement setup identifier used by the AP, the AP may instead directly use the second measurement setup identifier as the first measurement setup identifier. In other words, in this case, the first measurement setup identifier is the same as the second measurement setup identifier. For example, the second measurement setup identifier is the first ID, and the first measurement setup identifier is the second ID. If the existing set of measurement setup IDs in the AP includes the first ID, then the second ID does not belong to the existing set of measurement setup IDs in the AP. If the existing set of measurement setup IDs in the AP does not include the first ID, the AP may still use the first ID, in which case the second ID is equal to the first ID. Of course, even if the second measurement setup identifier is not a measurement setup identifier used by the AP (Proxy Sensing Initiator), the AP may, as an alternative, randomly select a value as the first measurement setup identifier that is not a measurement setup identifier used by the AP. In other words, in this case, the first measurement setup identifier and the second measurement setup identifier may be different values.

[0162] Optionally, after step S102, the measurement setup identifier determination method may further include: The proxy sensing initiator (AP) transmits third information to the sensing responder (e.g., STA3 in FIG. 3), where the third information includes the first measurement setup identifier. Optionally, in addition to carrying the first measurement setup identifier, the third information may further carry some parameters within the first measurement setup parameters, such as the bandwidth. The above steps S101 and S102 may be understood as a measurement setup procedure, and the first information may be understood as information in the measurement setup procedure. The third information may be information in a sensing procedure such as a measurement instance and the end of the measurement setup. In other words, the method for identifying the above-described measurement setup (i.e., when the AP functioning as a proxy identifies the measurement setup in the proxy sensing procedure, the AP needs to reuse a measurement setup ID different from the existing measurement setup ID in the AP) is applicable to the measurement setup procedure and is also applicable to sensing procedures such as measurement instances and the end of the measurement setup.

[0163] In this embodiment of the present application, the measurement setup ID set in the proxy sensing procedure is restricted so as not to belong to the existing measurement setup ID set in the AP, and as a result, the problem of setting the measurement setup identifier in the proxy sensing scenario can be solved. In addition, the measurement setup identifier set in the proxy sensing scenario is distinguished from the set of measurement setup identifiers in the common sensing scenario (or non-proxy sensing scenario), thereby avoiding confusion and avoiding affecting subsequent sensing measurement procedures. The identification method of the sensing responder may be further reused. In other words, the sensing responder can still identify the corresponding measurement setup by using <MAC address, measurement setup ID>. In this specification, the MAC address is the MAC address of the proxy sensing initiator (AP), that is, the proxy AP MAC address.

[0164] For a proxy sensing initiator (AP), the MAC address used to identify the measurement setup parameters in <Initiator MAC Address, Measurement Setup ID> may be carried in fields such as the transmission address (TA) and source address (SA) of the transmitted PPDU. However, for a sensing responder (e.g., STA3), the initiator's MAC address may be carried in fields such as the receiver address (RA) and destination address (DA) of the PPDU transmitted by the sensing responder. The initiator MAC address here is the MAC address of the proxy AP, i.e., the proxy AP MAC address. It should be further understood that, as specified herein, MAC addresses are used to participate in distinguishing measurement setups, and while some or all MAC addresses may be transmitted during transmission, not all MAC addresses are necessarily transmitted. This is also true below, so further details will not be explained again.

[0165] Embodiment 2 Figure 6 is another schematic flowchart of a measurement setup identifier determination method according to an embodiment of the present application. The measurement setup identifier determination method may be applied to the proxy sensing scenario shown in Figure 3. This method primarily provides an explanation of whether a set of measurement setup IDs in a proxy sensing procedure may belong to an existing set of measurement setup IDs in an AP. Whether a set of measurement setup IDs in a proxy sensing procedure may belong to an existing set of measurement setup IDs is determined based on whether the corresponding measurement setup parameters match. As shown in Figure 6, the measurement setup identifier determination method includes, but is not limited to, the following steps.

[0166] S201: The proxy sensing initiator (AP) acquires the first measurement setup parameters, which include the parameters used by the proxy sensing initiator and sensing responder in the proxy sensing procedure.

[0167] For an implementation of step S201 in this embodiment of the present application, please refer to the implementation of step S101 in Embodiment 1 (i.e., the embodiment shown in Figure 5). Details will not be described again here.

[0168] S202: The proxy sensing initiator (AP) transmits first information to the sensing responder (STA3), where the first information includes a first measurement setup parameter and a first measurement setup identifier, the first measurement setup identifier identifies the first measurement setup parameter, and if a third measurement setup identifier that identifies the same measurement setup parameter as the first measurement setup parameter exists in the first identifier set, the first measurement setup identifier is the third measurement setup identifier, or if the first measurement setup identifier does not belong to the first identifier set, or if no measurement setup identifier that identifies the same measurement setup parameter as the first measurement setup parameter exists in the first identifier set, the first measurement setup identifier does not belong to the first identifier set, and the first identifier set includes measurement setup identifiers used by the proxy sensing initiator (AP).

[0169] Optionally, after obtaining the first measurement setup parameter, the AP (Proxy Sensing Initiator) may set a measurement setup identifier (referred to as the first measurement setup identifier) ​​for the first measurement setup parameter, the measurement setup identifier identifies the first measurement setup parameter. Specifically, the AP (Proxy Sensing Initiator) may detect whether a measurement setup identifier that identifies the same measurement setup parameter as the first measurement setup parameter exists in the first identifier set (i.e., the set of measurement setup identifiers used by the Proxy Sensing Initiator (AP)). If a third measurement setup identifier that identifies the same measurement setup parameter as the first measurement setup parameter exists in the first identifier set, the AP (Proxy Sensing Initiator) may use the third measurement setup identifier as the first measurement setup identifier, or the AP (Proxy Sensing Initiator) may select a value not present in the first identifier set as the first measurement setup identifier. In other words, if a measurement setup parameter identified by a third measurement setup identifier in the first identifier set is the same as the first measurement setup parameter, then the first measurement setup identifier is either the third measurement setup identifier or the first measurement setup identifier does not belong to the first identifier set. If no measurement setup identifier identifies the same measurement setup parameter as the first measurement setup parameter in the first identifier set, the AP (Proxy Sensing Initiator) may select a value that is not in the first identifier set as the first measurement setup identifier. In other words, if no measurement setup identifier identifies the same measurement setup parameter as the first measurement setup parameter in the first identifier set, then the first measurement setup identifier does not belong to the first identifier set. The first identifier set includes the measurement setup identifiers used by the Proxy Sensing Initiator (AP).The measurement setup identifier used by the AP (Proxy Sensing Initiator) may include the measurement setup identifier used by the AP (Proxy Sensing Initiator) in a sensing procedure (in this case, a non-proxy sensing procedure), and / or the measurement setup identifier used by the AP (Proxy Sensing Initiator) in a proxy sensing procedure.

[0170] In other words, when an AP acting as a proxy identifies a measurement setup in a proxy sensing procedure, the AP can use an existing measurement setup ID in the AP to identify the measurement setup. Whether an existing measurement setup ID in the AP can identify a measurement setup depends on whether the parameter corresponding to the existing measurement setup ID between the AP (proxy sensing initiator) and the sensing responder (e.g., STA3) matches the parameter corresponding to the measurement setup that the requesting STA (e.g., STA1) wants to establish (in this case, the first measurement setup parameter). If the parameter corresponding to the existing measurement setup ID between the AP (proxy sensing initiator) and the sensing responder (e.g., STA3) matches the parameter corresponding to the measurement setup that the requesting STA (e.g., STA1) wants to establish (in this case, the first measurement setup parameter), the existing measurement setup ID in the AP can be reused. If the parameter corresponding to the existing measurement setup ID between the AP (proxy sensing initiator) and the sensing responder (e.g., STA3) does not match the parameter corresponding to the measurement setup that the requesting STA (e.g., STA1) wants to establish (in this case, the first measurement setup parameter), a new number is created to identify the new measurement setup. The existing measurement setup IDs in the AP include established measurement setup IDs that are set as initiators by the AP in proxy sensing procedures and established measurement setup IDs that are set as initiators by the AP in non-proxy sensing procedures.

[0171] Optionally, after setting a first measurement setup identifier for the first measurement setup parameter, the AP (Proxy Sensing Initiator) may send a single piece of information (referred to as the first information) containing the first measurement setup parameter and the first measurement setup identifier to the sensing responder (e.g., STA3 in Figure 3). In other words, the first measurement setup parameter is identified between the AP (Proxy Sensing Initiator) and the sensing responder (e.g., STA3) by using the first measurement setup identifier. After receiving the first information, the sensing responder (e.g., STA3) can establish an association relationship between the first measurement setup parameter and the first measurement setup identifier, so that the first measurement setup parameter can be uniquely indexed by using the first measurement setup identifier in subsequent sensing measurement procedures.

[0172] Optionally, if the requesting STA sets a second measurement setup identifier for the first measurement setup parameter and notifies the AP (Proxy Sensing Initiator), a mapping relationship may exist for the AP, specifically, the first measurement setup identifier corresponds to the second measurement setup identifier. In any embodiment, the AP may alternatively notify the requesting STA and / or sensing responder (e.g., STA3) of the mapping relationship between the first measurement setup identifier and the second measurement setup identifier. Correspondingly, the AP may alternatively notify the sensing responder (e.g., STA3) of the second measurement setup identifier, and / or the AP may further notify the requesting STA of the first measurement setup identifier.

[0173] It should be understood that both the first measurement setup identifier and the second measurement setup identifier identify the first measurement setup parameters. When the requesting STA exchanges content related to the first measurement setup identifier with the AP (Proxy Sensing Initiator), the AP (Proxy Sensing Initiator) and STA3 (Sensing Responder) use the second measurement setup identifier to indicate the related content.

[0174] If the second measurement setup identifier is not a measurement setup identifier in the first identifier set, in other words, if the second measurement setup identifier is different from any measurement setup identifier in the first identifier set, the AP (Proxy Sensing Initiator) may directly use the second measurement setup identifier as the first measurement setup identifier. In other words, in this case, the first measurement setup identifier is the same as the second measurement setup identifier.

[0175] Optionally, after step S202, the measurement setup identifier determination method may further include: the proxy sensing initiator (AP) transmits third information to the sensing responder (e.g., STA3 in Figure 3), where the third information includes the first measurement setup identifier. In other words, the AP (proxy sensing initiator) setting the measurement setup identifier for the first measurement setup parameters is applicable to the measurement setup procedure and also to sensing procedures such as measurement instance and measurement setup termination. Optionally, in addition to carrying the first measurement setup identifier, the third information may further carry some of the parameters within the first measurement setup parameters, such as bandwidth.

[0176] In this embodiment of the present application, the proxy AP (i.e., the proxy sensing initiator) determines whether to use an ID within the existing measurement setup ID set in the AP according to whether the parameter corresponding to the measurement setup in the proxy sensing procedure requested by the requesting STA (i.e., the first measurement setup parameter) is the same as the parameter corresponding to the measurement setup ID in the existing measurement setup ID set in the proxy AP (i.e., the first identifier set). In one aspect, it can solve the problem of setting the measurement setup identifier in the proxy sensing scenario, distinguish the measurement setup identifiers in different scenarios, and thereby avoid confusion. In another aspect, the identification method of the sensing responder can be reused. Specifically, the sensing responder can still identify the corresponding measurement setup by using <MAC address, measurement setup ID>. In yet another aspect, ID resources can be saved. Here, the MAC address is the MAC address of the proxy sensing initiator (AP), i.e., the proxy AP MAC address.

[0177] Embodiment 3 FIG. 7 is a schematic flowchart of a measurement setup method in a proxy sensing procedure according to an embodiment of the present application. The measurement setup method in the proxy sensing procedure can be applied to the proxy sensing scenario shown in FIG. 3. This method mainly provides an explanation that the measurement setup ID is completely independently set in the proxy sensing procedure by the AP transmitting a measurement setup ID that carries more information (such as proxy sensing by proxy (SBP) related information and requesting STA related information). As shown in FIG. 7, the measurement setup method in the proxy sensing procedure includes, but is not limited to, the following steps.

[0178] S301: The proxy sensing initiator (AP) acquires first measurement setup parameters, which include parameters used by the proxy sensing initiator and sensing responder in the proxy sensing procedure.

[0179] For an implementation of step S301 in this embodiment of the present application, please refer to the implementation of step S101 in Embodiment 1 (i.e., the embodiment shown in Figure 5). Details will not be described again here.

[0180] S302: The proxy sensing initiator (AP) transmits first information to the sensing responder (STA3), where the first information includes first measurement setup parameters, first measurement setup identifier, and fourth information, where the first measurement setup identifier identifies the first measurement setup parameters, and the fourth information includes information for identifying the requesting STA, and / or information indicating that the measurement setup requested to be established using the first information belongs to a proxy sensing procedure.

[0181] Optionally, after obtaining the first measurement setup parameter, the AP (Proxy Sensing Initiator) may set a measurement setup identifier (referred to as the first measurement setup identifier) ​​for the first measurement setup parameter, the measurement setup identifier identifies the first measurement setup parameter. The first measurement setup identifier may be set independently; in other words, the first measurement setup identifier may be a measurement setup identifier used by the AP (Proxy Sensing Initiator). Alternatively, the first measurement setup identifier may not be a measurement setup identifier used by the AP (Proxy Sensing Initiator); in other words, the first measurement setup identifier may be any value. For the meaning of the measurement setup identifier used by the AP (Proxy Sensing Initiator), please refer to the explanation above, and a detailed explanation is omitted here. The AP (Proxy Sensing Initiator) may obtain fourth information, which may include information for identifying the requesting STA, and / or information indicating that the measurement setup requested to be established using the first information belongs to a proxy sensing procedure. Information for identifying a requesting STA may include one or more of the following: the requesting STA identifier, part or all of the requesting STA's MAC address, or the requesting STA's virtual number. The requesting STA identifier may be part or all of the requesting STA's association identifier (AID), or part or all of the requesting STA's unassociated station identifier (UID). The requesting STA's virtual number may be set by the AP (Proxy Sensing Initiator). Information indicating that the measurement setup requested to be established using the first information belongs to a proxy sensing procedure may be 1 bit. When the bit is set to 1, it indicates that the measurement setup requested to be established using the first information belongs to a proxy sensing procedure; when the bit is set to 0, it indicates that the measurement setup requested to be established using the first information does not belong to a proxy sensing procedure, or is reserved.Of course, when the bit is set to 0, this indicates that the measurement setup requested to be established using the first information belongs to a proxy sensing procedure, or when the bit is set to 1, this indicates that the measurement setup requested to be established using the first information does not belong to a proxy sensing procedure, or that it is reserved. This is not limited to this embodiment of the present application.

[0182] Optionally, the AP (Proxy Sensing Initiator) may set a first measurement setup identifier for the first measurement setup parameter and, after obtaining the fourth information, transmit a single piece of information (referred to as the first information) containing the first measurement setup parameter, the first measurement setup identifier, and the fourth information to the sensing responder (e.g., STA3 in Figure 3). After receiving the first information, the sensing responder (e.g., STA3) establishes an association relationship between the first measurement setup parameter, the first measurement setup identifier, and the fourth information, and as a result, the first measurement setup parameter can be uniquely indexed by using the first measurement setup identifier and the fourth information in subsequent sensing measurement procedures.

[0183] In other words, when the AP functioning as a proxy transmits the measurement setup identifier in the proxy sensing procedure to the sensing responder, Information 1 (i.e., the fourth information) may be carried. Information 1 may be the requesting STA (STA1) related information (e.g., AID, UID, the MAC address and virtual number of STA1 (the virtual number corresponds to the requesting STA)), and / or proxy sensing related information (e.g., this may indicate that the measurement setup belongs to the measurement setup in the proxy sensing procedure). Since the requesting STA related information and the proxy sensing related information are used for distinction, the sensing responder can distinguish the measurement setup parameters corresponding to the measurement setup ID based on these information. Therefore, the measurement setup ID may be independently set in the proxy sensing procedure. For example, the requesting STA related information is carried. In this case, the sensing responder can distinguish different measurement setup parameters identified by the same measurement setup ID by using <STA1 MAC address, measurement setup ID> or <AP MAC address, STA1 MAC address, measurement setup ID>. In other words, one element or a combination of multiple elements of <AP MAC address, STA1 MAC address, measurement setup ID, proxy sensing related information> may be used as a criterion for identifying the measurement setup.

[0184] Optionally, when the requesting STA sets the second measurement setup identifier for the first measurement setup parameters and notifies the AP (proxy sensing initiator), the mapping relationship may not exist in the AP (proxy sensing initiator). In other words, when the AP sets the measurement setup identifier for the first measurement setup parameters, it directly uses the second measurement setup identifier.

[0185] Optionally, after step S302, the measurement setup method in the proxy sensing procedure may further include: the proxy sensing initiator (AP) transmits third information to the sensing responder (e.g., STA3 in Figure 3), where the third information includes a first measurement setup identifier and fourth information. In other words, the method by which the AP (proxy sensing initiator) transmits a measurement setup ID carrying fourth information in the proxy sensing procedure is applicable to the measurement setup procedure and is also applicable to sensing procedures such as measurement instance and measurement setup termination. Optionally, in addition to carrying the first measurement setup identifier and fourth information, the third information may further carry some of the parameters of the first measurement setup parameters, such as bandwidth.

[0186] Optionally, the fourth piece of information may be a newly added field within the frame; in other words, the fourth piece of information may have a corresponding field within the frame, such as the MAC address field of the requesting STA or a proxy sensing-related information field. If the frame carrying the fourth piece of information is a broadcast frame, such as a null data packet announcement (NDPA) frame or a trigger frame (TF), the fourth piece of information may be located in a common-level field of the frame, such as a common info field. Of course, the fourth piece of information may alternatively be located in a user-level field, such as a user info field or an STA info field. Alternatively, the fourth piece of information may be carried in one or more special user info fields. For example, a special user info field may be identified by using a special AID.

[0187] In this embodiment of the present application, when transmitting a measurement setup ID in a proxy sensing procedure, the proxy sensing initiator (AP) carries information to identify the requesting STA and / or information indicating that the established measurement setup belongs to a proxy sensing procedure, thereby assisting the sensing responder (STA3) in identifying different measurement setups. In another view, this embodiment of the present application solves the problem of setting a measurement setup identifier in a proxy sensing scenario, thereby avoiding confusion.

[0188] The above description details the method provided in this application. To facilitate the implementation of the above solution in the embodiments of this application, embodiments of this application further provide corresponding apparatus or devices.

[0189] In embodiments of this application, the proxy sensing initiator (AP) may be divided into functional modules based on embodiments of the methods described above. For example, each functional module may be obtained by division based on corresponding functions, or two or more functions may be integrated into a single processing module. The integrated module may be implemented in hardware form or in the form of a software functional module. Note that in embodiments of this application, the division into modules is illustrative and merely a logical functional division. In actual implementations, other division methods may be used. The communication device in embodiments of this application will now be described in detail with reference to Figures 8 and 9. The communication device is a proxy sensing initiator (AP). Furthermore, the communication device may be a device within the proxy sensing initiator (AP).

[0190] When an integrated unit is used, please refer to Figure 8. Figure 8 is a schematic diagram of the structure of a communication device according to an embodiment of the present application. The communication device may be a proxy sensing initiator (AP) or a chip within a proxy sensing initiator (AP), such as a Wi-Fi chip. As shown in Figure 8, the communication device includes an acquisition module 11 and a transceiver module 12.

[0192] Optionally, the acquisition module 11 includes a receiving unit 111 and a determination unit 112. The receiving unit 111 is configured to receive second information transmitted by the requesting station STA, the second information including second measurement setup parameters, the second measurement setup parameters including all or some of the parameters used by the proxy sensing initiator and sensing responder in the proxy sensing procedure.

For the sake of brevity, further details will not be explained again here.

[0200] In one design, the acquisition module 11 is configured to acquire a first measurement setup parameter, where the first measurement setup parameter includes a parameter used by the proxy sensing initiator and the sensing responder in the proxy sensing procedure. The transceiver module 12 is configured to transmit first information to the sensing responder, where the first information includes the first measurement setup parameter and a first measurement setup identifier, where the first measurement setup identifier identifies the first measurement setup parameter. If a third measurement setup identifier that identifies the same measurement setup parameter as the first measurement setup parameter exists in the first identifier set, then the first measurement setup identifier is either the third measurement setup identifier, or the first measurement setup identifier does not belong to the first identifier set, or if no measurement setup identifier that identifies the same measurement setup parameter as the first measurement setup parameter exists in the first identifier set, then the first measurement setup identifier does not belong to the first identifier set. The first identifier set includes measurement setup identifiers used by the proxy sensing initiator.

For brevity, further details will not be explained again here.

[0208] In one design, the acquisition module 11 is configured to acquire first measurement setup parameters, where the first measurement setup parameters include parameters used by the proxy sensing initiator and sensing responder in a proxy sensing procedure.

[0209] Optionally, the information for identifying the requesting STA may include one or more of the following: the requesting STA's identifier, part or all of the requesting STA's media access control MAC address, and the requesting STA's virtual number. The requesting STA's identifier is part or all of the requesting STA's association identifier, or part or all of the requesting STA's non-associated station identifier.

[0210] Optionally, the acquisition module 11 includes a receiving unit 111 and a determination unit 112.

[0214] The acquisition module 11 is sometimes also called the processing module.

[0215] The communication device in this design may correspond to Embodiment 3, and it should be understood that the above-mentioned operations or functions of the units in the communication device are used to implement the corresponding operations of the proxy sensing initiator (AP) in Embodiment 3. For the sake of brevity, further details will not be explained again here.

Please understand that any product in any form having the functionality of the proxy sensing initiator (AP) shown in Figure 8 is covered within the scope of protection of the embodiments of this application. Please further understand that the following description is merely an example and is not limited to the product form of the proxy sensing initiator (AP) in the embodiments of this application.

[0217] In possible product configurations, the proxy sensing initiator (AP) described in the embodiments of this application can be implemented by a general bus architecture.

[0218] For ease of explanation, please refer to Figure 9. Figure 9 is a schematic diagram of the structure of a communication device 1000 according to an embodiment of the present application. The communication device 1000 may be a proxy sensing initiator (AP) or a chip within a proxy sensing initiator (AP). Figure 9 shows only the main components of the communication device 1000. In addition to the processor 1001 and the transceiver 1002, the communication device may further include a memory 1003 and an input / output device (not shown).

The control circuit is mainly configured to perform conversions between baseband signals and radio frequency signals and to process radio frequency signals. The antenna is mainly configured to transmit and receive radio frequency signals in the form of electromagnetic waves. Input / output devices, such as a touchscreen, display, or keyboard, are mainly configured to receive data entered by the user and output data to the user.

[0220] After the communication device is powered on, the processor 1001 can read the software program in the memory 1003, interpret and execute the instructions of the software program, and process the data of the software program. When it is necessary to transmit data wirelessly, the processor 1001 performs baseband processing on the data to be transmitted and then outputs the baseband signal to the radio frequency circuit. After performing radio frequency processing on the baseband signal, the radio frequency circuit transmits the radio frequency signal in the form of electromagnetic waves via the antenna. When transmitting data to the communication device, the radio circuit receives the radio frequency signal via the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor 1001. The processor 1001 converts the baseband signal into data and processes the data.
