Description

[Technical Field]

[0001] This application claims priority to Chinese Patent Application No. 202111679651.4, entitled "MEASUREMENT SETUP IDENTIFIER DETERMINING METHOD AND RELATED APPARATUS," filed with the State Intellectual Property Office of China on December 31, 2021, which is incorporated herein by reference in its entirety.

[0002] Technical Field The present application relates to the field of wireless communication technologies, and more particularly to a measurement setup identifier determination method and related apparatus. [Background technology]

[0003] With the widespread deployment of wireless fidelity (Wi-Fi) devices and increasing sensing requirements, sensing performed by widely available Wi-Fi devices is a hot topic of current research. In everyday life, signals transmitted from Wi-Fi devices are typically received only after being reflected, diffracted, and scattered by various obstacles. As a result, the actual received signal is usually a superposition of multiple signals. Therefore, wireless signals can sense the physical environment through which they pass, and the surrounding environment can be inferred by analyzing the wireless signals "modulated" by various obstacles, thereby deriving wireless local area network (WLAN) sensing technology. WLAN sensing is a technology expected to have a wide range of applications. WLAN sensing technology uses widely deployed Wi-Fi devices 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 from the received signals using specific algorithms for analysis. This makes it possible to obtain information about the surrounding environment.

[0004] The sensing procedure defined in the 802.11bf standard mainly includes 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 the sensing responder to exchange and unify parameters / features used in the sensing procedure. In the sensing procedure, the sensing initiator and the sensing responder may exchange and unify multiple groups of parameters / features used in the sensing procedure. Therefore, for clear identification, a method of labeling the measurement setup is proposed to distinguish different groups of parameters / features used in the sensing procedure.

[0005] Because the 802.11bf protocol currently does not support sensing between two non-access point stations (STAs), there is a special scenario in the sensing procedure: a station (STA) needs an access point (AP) to help it complete measurements with another sensing responder. For ease of explanation, this special scenario is referred to herein as the proxy sensing scenario. Therefore, how to identify the measurement setup in the proxy sensing scenario is a problem worth considering. Summary of the Invention [Problem to be solved by the invention]

[0006] Embodiments of the present application provide a measurement setup identifier determination method and related devices to solve the problem of setting a measurement setup ID in a proxy sensing scenario, so that the measurement setup identifier set in the proxy sensing scenario can be distinguished from the measurement setup identifier set 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, and it should be understood that the following implementations and advantageous effects of different aspects are mutually referenced.

[0008] According to a first aspect, the present application provides a measurement setup identifier determination method. The method further includes a proxy sensing initiator (AP) acquiring first measurement setup parameters and sending 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 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 the 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) requests the AP to perform sensing measurements as a proxy of the requesting STA.

[0010] Optionally, after receiving the first information, the first sensing responder (STA3) establishes 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 a subsequent sensing measurement procedure.

[0011] In this application, the measurement setup identifier used by a 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.

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

[0013] In this solution, the measurement setup ID set in the proxy sensing procedure is restricted to not belong to the existing measurement setup ID set in the AP, so that 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 measurement setup identifier set in the common sensing scenario (or the non-proxy sensing scenario), thereby avoiding confusion and affecting the subsequent sensing measurement procedure.

[0014] In relation to the first aspect, in a possible implementation, the proxy sensing initiator (AP) acquiring the first measurement setup parameters includes the proxy sensing initiator (AP) receiving second information transmitted by the requesting station (STA), where the second information includes second measurement setup parameters, and the second measurement setup parameters 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 station (STA) may determine the first measurement setup parameters through negotiation.

[0015] In relation to the first 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 sent 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 relevant parameters (i.e., the first measurement setup parameters) of the measurement setup that the requesting STA wants to establish, and the proxy sensing initiator (AP) cannot change the relevant parameters, so the proxy sensing initiator (AP) does not need to negotiate with the requesting STA about the relevant parameters.

[0016] Optionally, the second information further includes a second measurement setup identifier. The second measurement setup identifier may identify the first measurement setup parameter. When the second information further includes the 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. In this way, when the requesting STA exchanges content related to the first measurement setup identifier with the proxy sensing initiator (AP), the proxy sensing initiator (AP) and the sensing responder (STA3) indicate the related content using the second measurement setup identifier.

[0017] Optionally, when the second measurement setup identifier is not the 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, 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.

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

[0019] Optionally, in addition to carrying the first measurement setup identifier, the third information further carries part of the parameters in the first measurement setup parameters, for example the bandwidth.

[0020] According to a second aspect, the present application provides a communications device. The communications device may be a proxy sensing initiator (AP) or a chip within the proxy sensing initiator (AP), such as a Wi-Fi chip. The communications device includes: an acquisition module configured to acquire first measurement setup parameters, the first measurement setup parameters including parameters used by the proxy sensing initiator (AP) and a sensing responder (STA3) in a proxy sensing procedure; and a transceiver module configured to transmit first information to the sensing responder, the first information including the first measurement setup parameters and a first measurement setup identifier, the first measurement setup identifier identifying the first measurement setup parameters, and the first measurement setup identifier being different from the 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 determining unit. The receiving unit is configured to receive second information transmitted by the requesting station (STA), where the second information includes second measurement setup parameters, and the second measurement setup parameters include all or some of parameters used by the proxy sensing initiator (AP) and the sensing responder (STA3) in the proxy sensing procedure. The determining unit is configured to determine the 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 in the acquisition module is configured to receive second information transmitted by the requesting STA, where the second information includes first measurement setup parameters.

[0023] Optionally, the second information further includes a second measurement setup identifier, the second measurement setup identifier corresponding 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 relation to the second aspect, in a possible implementation, 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.

[0026] In relation to 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 measurement setup identifier determination method. The method further includes a proxy sensing initiator (AP) acquiring 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 parameter. If a third measurement setup identifier identifying 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 the first measurement setup identifier does not belong to the first identifier set, or if no measurement setup identifier identifying 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. The first identifier set includes the measurement setup identifier used by the proxy sensing initiator.

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

[0029] Optionally, after receiving the first information, the sensing responder (STA3) can establish an association relationship between the first measurement setup parameter and the first measurement setup identifier, thereby uniquely indexing the first measurement setup parameter in a subsequent sensing measurement procedure by using the first measurement setup identifier.

[0030] In this application, 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.

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

[0032] In this solution, when an AP acting as a proxy (proxy sensing initiator) identifies a measurement setup in a proxy sensing procedure, whether to use an ID in an existing measurement setup ID set in the AP is determined by determining whether a first measurement setup parameter is the same as a parameter corresponding to a measurement setup ID in an existing measurement setup ID set (i.e., a first identifier set) in the proxy AP (proxy sensing initiator). In this way, the problem of setting a measurement setup identifier in a proxy sensing scenario can be 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) acquiring the first measurement setup parameters includes the proxy sensing initiator (AP) receiving second information transmitted by the requesting STA, the second information including second measurement setup parameters, and the second measurement setup parameters including 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 proxy sensing initiator (AP) obtaining the first measurement setup parameters includes the proxy sensing initiator (AP) receiving second information sent 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 relevant parameters (i.e., the first measurement setup parameters) of the measurement setup that the requesting STA wants to establish, and the proxy sensing initiator (AP) cannot change the relevant parameters, so the proxy sensing initiator (AP) does not need to negotiate with the requesting STA about 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 parameter. When the second information further includes the 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. In this way, when the requesting STA exchanges content related to the first measurement setup identifier with the proxy sensing initiator (AP), the proxy sensing initiator (AP) and the sensing responder (STA3) indicate the related content using the second measurement setup identifier.

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

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

[0038] According to a fourth aspect, the present application provides a communications device. The communications device may be a proxy sensing initiator (AP) or a chip within the proxy sensing initiator (AP), such as a Wi-Fi chip. The communications device includes: an acquisition module configured to acquire first measurement setup parameters, the first measurement setup parameters including parameters used by the proxy sensing initiator and a sensing responder in a proxy sensing procedure; and a transceiver module configured to transmit first information to the sensing responder, the first information including the first measurement setup parameters and a first measurement setup identifier, the first measurement setup identifier identifying the first measurement setup parameters. 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 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 determining unit.

The virtual number of the requesting STA may be set by the AP (proxy sensing initiator). The information indicating that the measurement setup requested to be established by using the first information belongs to the proxy sensing procedure may be 1 bit. When the bit is set to 1, this indicates that the measurement setup requested to be established by using the first information belongs to the proxy sensing procedure. When the bit is set to 0, this indicates that the measurement setup requested to be established by using the first information does not belong to the proxy sensing procedure or is reserved.

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

[0095] In the description of this application, unless otherwise specified, " / " means "or." For example, "and / or" merely describes an association relationship between related objects and indicates that three relationships may exist. For example, A and / or B may represent the following three cases: only A is present, both A and B are present, or only B is present. In addition, "at least one" means one or more, and "multiple" means two or more. "At least one of the following items (components)" or similar expressions refers to any combination of these items, including any combination of a single item (component) or multiple items (components). 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 execution order, and terms such as "first" and "second" do not indicate clear distinctions.

[0097] In this application, the terms "an example" or "for example" are used to denote giving an example, example, or illustration. Any embodiment or design scheme described in this application as "an example," "such as," or "for example" should not be described as more preferred or having more advantages than another embodiment or design scheme. Rather, use of terms such as "an example," "such as," "for example," etc. is intended to concretely present the relevant concept.

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

[0099] In the embodiments of the present application, it should be understood that "B corresponding to A" indicates that B is associated with A and 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 based only 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 contents, terms or nouns relevant to this application.

[0101] 1. Four roles in the sensing procedure

[0102] A sensing initiator is a station that starts a sensing procedure (STA that starts a WLAN sensing procedure).

[0103] A sensing responder is a station that participates in a sensing procedure initiated by a sensing initiator (a 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 that receives a PPDU transmitted by a sensing transmitter and performs sensing measurements in the sensing procedure (a STA that receives a PPDU transmitted by a sensing transmitter and performs sensing measurements in the sensing procedure).

[0106] 2. Sensing procedure

[0107] The sensing procedure mainly includes five phases:

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

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

[0110] Measurement instance: A sensing measurement is performed in a measurement instance. One measurement instance allows multiple sensing responders to participate.

[0111] Measurement setup termination: Measurement setup termination is used to terminate the measurement setup corresponding to a sensing responder, such that the sensing responder is no longer bound to the corresponding measurement setup, although the sensing responder 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 measurements.

[0113] To more clearly explain how the above sensing procedure works, the following description is provided with reference to the accompanying drawings.

[0114] FIG. 1 is a schematic diagram of a sensing procedure according to an embodiment of the present application. As shown in FIG. 1, the sensing procedure illustrated in FIG. 1 includes 16 phases. The 16 phases are merely exemplary and may be temporally discontinuous. For example, another phase may exist between Phase 6 and Phase 7, but this is not shown in FIG. 1. It should be understood that FIG. 1 is merely an example, and that in an actual application, there may be more or fewer phases of the sensing procedure than those illustrated in FIG. 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., a sensing session setup procedure. Phase 2 indicates that related parameters that need to be used in the sensing procedure are configured for the station, i.e., sensing measurement setup. It should be understood that in Phase 2, a method of labeling sensing measurement setups, i.e., measurement setup ID=1, is used to clearly identify different measurement setups. In this application, a measurement setup identifier (measurement setup ID) can be understood as identifying a group of parameters or a group of features that need to be used in the sensing procedure for exchange and unification between the sensing initiator and the 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 (a group of parameters or features is used for the sensing measurement). Therefore, a station with AID=1 can perform measurements in a measurement instance. Each measurement instance also has a corresponding label. In summary, phases 1, 2 and 3 are used to join stations to a sensing session and start measurements and feedback.

[0115] Phase 4 indicates that another measurement instance occurs. Here, to distinguish the measurement instance from the previous measurement instance, the identifier of the measurement instance is now +1, i.e., the measurement instance corresponding to measurement setup 1. 21 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 stations with AID=1, specifically, they are used to configure measurement setup 2 and perform measurements and feedback.

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

[0117] Phase 10 shows 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 related parameters). In this case, the station with AID=1 remains bound to measurement setup 1. Phases 11 and 12 show that 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 ends the sensing session.

[0119] Phases 14, 15, and 16 are similar to phases 1, 2, and 3, and show that the station with AID=3 joins 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 a measurement instance.

[0120] The four phases, i.e., sensing session setup, measurement setup, measurement setup termination, and sensing session termination, are all one-to-one setup phases. The sensing session setup phase is used as an example. One sensing session setup corresponds to one sensing initiator and one sensing responder. Of course, a sensing initiator may alternatively set up sensing sessions with multiple stations simultaneously, for example, in an OFDMA or MU-MIMO format, but multiple sensing sessions are set up simultaneously.

[0121] The measurement instance phase is different from the above four phases: one measurement instance can have one-to-many cases, such as one-to-many announcements and 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, the sensing initiator may use an NDPA (NDP announcement) to notify corresponding stations that the sensing initiator will soon transmit an NDP. The NDPA is used to notify stations that they need to listen to the NDP and other configuration information, so that the corresponding stations can measure the subsequently transmitted NDP to learn channel information. In the trigger frame sounding phase, the sensing initiator may use a trigger frame to trigger the peer end to transmit an NDP and measure the transmitted NDP to perform sensing. In addition, the function of the polling phase is to ensure that the polled stations can participate in measurement and feedback in the current measurement instance.

[0124] For non-trigger-based sensing measurement instances, the peer end's transmission of the NDP may be introduced by transmitting an NDPA or in other ways.

[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 a group of 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 a sensing initiator. FIG. 2 is a schematic diagram for setting a 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 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, but 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 are two ways to set up a session between the two devices shown in FIG. 2. The session setup between the AP and STA1 in FIG. 2 is used as an example. The session setup between the AP and STA1 may be a sensing session set up by using the AP as the sensing initiator, or may be a sensing session set up by using STA1 as the sensing initiator. In this case, the measurement setup indicated by the third dashed line from left to right in FIG. 2 may be performed after the sensing session is set up by using the AP as the sensing initiator, or may be performed after the sensing session is set up by using STA1 as the sensing initiator. In other words, in this embodiment of the present application, a specific session setup method is not limited, and the sensing initiator in the session setup procedure does not necessarily need to be the same as the sensing initiator in the measurement setup procedure, and may be different.

[0129] Because the current protocol does not support sensing between two non-access point stations (non-AP STAs), there is a special scenario in the sensing procedure: a STA wants the AP to help it complete measurements with another sensing responder. For example, a device in a room wants the AP to help it feedback channel state information (CSI) for devices connected to the AP in all rooms of the house. This special scenario is called the proxy sensing scenario.

[0130] In order to support this special scenario in the sensing procedure (in other words, to support the proxy sensing scenario), a proxy sensing procedure is proposed. Figure 3 is a schematic diagram of the 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, 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: a requesting STA (or sensing by proxy request station (SBP request STA), SBP = sensing by proxy) requests the AP to act as a proxy for the requesting STA and perform measurements; the AP performs sensing with the sensing responder (e.g., STA2 or STA3); and the AP reports 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 an AP and a requesting STA, the requesting STA may also act as a sensing responder in the sensing procedure.

[0131] In this application, the requesting STA may be understood as an initial sensing initiator, and the AP may be understood as a proxy sensing initiator (or simply called "proxy" for short).

[0132] In the proxy sensing scenario shown in FIG. 3, when the AP participates in non-proxy sensing (e.g., the AP functions as a sensing initiator and performs sensing with STA3) and participates in proxy sensing (e.g., the AP functions as a proxy for STA1 and performs sensing with STA3), since the MAC addresses of the sensing initiators carried in the PPDUs 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 sensing measurement by using the measurement setup identifier.

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

[0135] An access point (e.g., the AP in FIG. 3 ) is a device having wireless communication capabilities, supports communication using a WLAN protocol, and has the capability of communicating with other devices (e.g., stations or other access points) in a WLAN network, although it may also have the capability of communicating with other devices. In a WLAN system, an access point may be referred to as an access point station (AP STA). The device having wireless communication capabilities may be an entire device, or a chip or processing system mounted on the entire device. The device equipped with the chip or processing system may implement the methods and functions of the embodiments of the present application under the control of the chip or processing system. An AP in the embodiments of the present application is a device that provides services to STAs and may support 802.11 series protocols. For example, an AP may be a communication entity such as a communication server, router, switch, or bridge. An AP may include various forms of macro base stations, micro base stations, relay stations, etc. Of course, an 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 the present application.

[0136] A station (e.g., STA1, STA2, or STA3 in FIG. 3) is a device having wireless communication capabilities, supports communication using a WLAN protocol, and is capable of communicating with other stations or access points in a WLAN network. In a WLAN system, a station may be referred to as a non-access point station (non-AP STA). For example, a STA is any user communication device that enables a user to communicate with an AP and further communicate with a WLAN. A device having wireless communication capabilities may be an entire device, or a chip or processing system mounted on the entire device. A device equipped with a chip or processing system may implement the methods and functions in the embodiments of the present application under the control of the chip or processing system. For example, a STA may be an Internet-connectable 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, the 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 gaming device or system, a global positioning system device, etc. The STA may alternatively be a chip and processing system within the terminal.

[0137] WLAN systems can provide high-speed and low-latency transmission. With the continuous evolution of WLAN application scenarios, WLAN systems are applied to more scenarios and industries, such as the Internet of Things industry, the Internet of Vehicles industry, the banking industry, corporate offices, stadium exhibition halls, concert halls, hotel rooms, dormitories, hospital wards, classrooms, supermarkets, squares, streets, manufacturing workshops, and warehouses. Of course, a device (e.g., an access point or station) supporting WLAN communication may be a sensor node (e.g., a smart water meter, a smart electricity meter, or a smart air detection node) in a smart city, a smart device (e.g., a smart camera, a projector, a display, a television, a stereo, a refrigerator, or a washing machine) in a smart home, a node in the Internet of Things, an entertainment terminal (e.g., an augmented reality (AR), a virtual reality (VR), or another wearable device), a smart device (e.g., a printer, a projector, a speaker, or a stereo) in a smart office, an Internet of Vehicles in the Internet of Vehicles, an infrastructure in daily life scenarios (e.g., a vending machine, a self-service navigation station in a supermarket, a self-service cash register device, or a self-service ordering machine), a device in a large sports or music venue, etc. Note that the specific forms of the STA and AP are not limited to the embodiments of the present application and are merely examples for the purpose of explanation in this specification.

[0138] It should be understood that the 802.11 standard focuses on the physical layer (PHY) and medium access control (MAC) layers. For one example, see FIG. 4a. FIG. 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 may be single-antenna / single-radio frequency. The antenna / radio frequency is used to transmit and receive data packets (herein, data packets are also referred to as physical layer protocol data units (PHY protocol data units, PPDUs)). In one implementation, the antenna or radio frequency part of the AP may be separated from the main body of the AP, i.e., may be located remotely. In FIG. 4a, the AP may include a physical layer processing circuit and a medium access control 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. For another example, see FIG. 4b. FIG. 4b is a schematic diagram of the structure of a station according to an embodiment of the present application. FIG. 4b is a schematic diagram of the structure of a single-antenna / single-radio frequency STA. In a practical scenario, the STA may be a multi-antenna / multi-radio frequency device with more than two antennas. The antennas / radio frequencies are used to transmit 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., may be located remotely. In FIG. 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 following describes in detail the technical solutions provided in this application with reference to further accompanying drawings.

[0140] In this application, unless otherwise specified, identical or similar parts of embodiments or implementations shall refer to each other. In the embodiments and implementations / implementation methods of the embodiments of this application, unless otherwise specified or unless a logical contradiction occurs, the terms and / or descriptions shall be consistent and may be cross-referenced between different embodiments and implementations / implementation methods of the embodiments. The technical features of different embodiments and the 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 protection scope of this application.

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

[0142] Embodiment 1 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 FIG. 3. This method mainly describes 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 FIG. 5, the measurement setup identifier determination method includes, but is not limited to, the following steps:

[0143] S101: A proxy sensing initiator (AP) obtains first measurement setup parameters, where the first measurement setup parameters include parameters used by the proxy sensing initiator and a sensing responder in a proxy sensing procedure.

[0144] In one implementation, a requesting STA (e.g., STA1 in FIG. 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) parameters related to the measurement setup that the requesting STA wants to establish (referred to as second measurement setup parameters). The measurement setup parameters in this application are 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 parameters (i.e., first measurement setup parameters) that will ultimately be used by the proxy sensing initiator (AP) and the sensing responder (e.g., STA3 in FIG. 3) in the proxy sensing procedure. For example, after receiving the second measurement setup parameters, the AP (proxy sensing initiator) determines third measurement setup parameters based on the second measurement setup parameters and sends the determined third measurement setup parameters to the requesting STA. If the requesting STA agrees to the third measurement setup parameters, the requesting STA sends agreement information to the AP (proxy sensing initiator). After receiving the agreement information, the AP (proxy sensing initiator) uses the third measurement setup parameters as the first measurement setup parameters. If the requesting STA does not agree to the third measurement setup parameters, the requesting STA may send new measurement setup parameters (the new measurement setup parameters are different from the second and third measurement setup parameters) to the AP (proxy sensing initiator). After receiving the new measurement setup parameters, if the AP (proxy sensing initiator) agrees to use the new measurement setup parameters, the AP (proxy sensing initiator) uses the new measurement setup parameters as the first measurement setup parameters.If the AP (proxy sensing initiator) does not agree to use the new measurement setup parameters, the AP (proxy sensing initiator) and the requesting STA may continue to negotiate 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 the 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 the sensing responder in the proxy sensing procedure, the AP may negotiate the remaining part of the parameters with the requesting STA, or 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 by the requesting STA (STA1) to the AP, or may be carried in a separate information / frame, which is not limited in this embodiment of the present application.

[0147] Optionally, when transmitting the related parameters of the measurement setup that the requesting STA wants to establish (i.e., the second measurement setup parameters) to the AP (proxy sensing initiator), the requesting STA may also simultaneously transmit a measurement setup identifier (the measurement setup identifier is set by the requesting STA, and the measurement setup identifier is denoted as the second measurement setup identifier). In other words, the second measurement setup parameters and the second measurement setup identifier may be included in one information / frame, for example, in the second information. Of course, the second measurement setup parameters and the second measurement setup identifier may be carried in different 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 in 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 wants to establish and that are sent by the STA to the AP) and the measurement setup parameters in the negotiation process (such as the aforementioned third measurement setup parameter and the aforementioned new measurement setup parameter). When and after the AP negotiates with the requesting STA to determine the first measurement setup parameters, 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 negotiation.

[0148] In this way, when the requesting STA wants the AP to establish multiple measurement setups on behalf of the requesting STA, 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 the second measurement setup identifier, so that when feeding back the channel state information, 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] It should be understood that if the requesting STA requests only one measurement setup from the AP (proxy sensing initiator), the requesting STA may not need to set the second measurement setup identifier for the first measurement setup parameters, because all the channel state information received by the requesting STA is the channel state information corresponding to the first measurement setup parameters, and no confusion occurs.

[0150] In another implementation, a requesting STA (e.g., STA1 in FIG. 3) may request an AP to perform sensing measurements acting as a proxy for the requesting STA. The requesting STA may further send second information to the AP (proxy sensing initiator), where the second information includes parameters used by the proxy sensing initiator (AP) and the sensing responder (e.g., STA3 in FIG. 3) in the proxy sensing procedure. In other words, the second information includes first measurement setup parameters. That is, the related 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) may then 2 Receive the information and 1Obtain measurement setup parameters. In other words, the requesting STA directly notifies the AP (proxy sensing initiator) of the relevant parameters of the measurement setup that the requesting STA wants to establish, and the AP (proxy sensing initiator) does not need to negotiate with the requesting STA regarding the relevant parameters because the AP (proxy sensing initiator) cannot change the relevant 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.

[0151] Optionally, the second information may be carried in a request message sent by the requesting STA (STA1) to the AP, or may be carried in an independent information / frame, which is not limited in 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 further simultaneously send a measurement setup identifier (the measurement setup identifier is set by the requesting STA, and the measurement setup identifier is denoted as a 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 located in different information / frames. The second measurement setup identifier may 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 FIG. 3) requests an AP to act as a proxy for the requesting STA and perform sensing measurements. After receiving the request from the requesting STA, the AP (i.e., the proxy sensing initiator) may determine parameters to be used by the AP (proxy sensing initiator) and the sensing responder (e.g., STA3 in FIG. 3) in the proxy sensing procedure, in other words, may determine 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, a measurement setup identifier (denoted as a second measurement setup identifier) ​​may be carried when the requesting STA requests the AP to act as a proxy for the requesting STA and perform sensing measurements. After receiving the request from the requesting STA, the AP (proxy sensing initiator) determines 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, the requesting STA sets a measurement setup identifier (i.e., a second measurement setup identifier) ​​when requesting the AP to act as a proxy for the requesting STA. In this case, the second measurement setup identifier does not identify a parameter, or the parameter identified by the second measurement setup identifier is 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) sends first information to the sensing responder (STA3), where the first information includes first measurement setup parameters and a 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 parameters, the AP (proxy sensing initiator) may set a measurement setup identifier (denoted as first measurement setup identifier) ​​for the first measurement setup parameters, where the measurement setup identifier identifies the first measurement setup parameters. 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 the sensing procedure (here, the non-proxy sensing procedure) and / or the measurement setup identifier used by the AP (proxy sensing initiator) in the proxy sensing procedure. In other words, the existing measurement setup ID in the AP set includes an established measurement setup ID set by the AP as the initiator in a proxy sensing procedure, and an established measurement setup ID set by the AP as the initiator in a non-proxy sensing procedure.

[0158] Optionally, after setting the first measurement setup identifier for the first measurement setup parameter, the AP (proxy sensing initiator) may send a piece of information (denoted as first information) including the first measurement setup parameter and the first measurement setup identifier to the sensing responder (e.g., STA3 in FIG. 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 establish an association relationship between the first measurement setup parameter and the first measurement setup identifier, and thus can uniquely index the first measurement setup parameter by using the first measurement setup identifier in a subsequent sensing measurement procedure.

[0159] Optionally, when the requesting STA configures a second measurement setup identifier for the first measurement setup parameters and notifies the AP (proxy sensing initiator), a mapping relationship may exist within the AP (proxy sensing initiator). Specifically, the first measurement setup identifier configured by the AP (proxy sensing initiator) for the first measurement setup parameters corresponds to the second measurement setup identifier configured by the requesting STA for the first measurement setup parameters. 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 parameter. 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.

[0161] If the second measurement setup identifier is not the 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 (proxy sensing initiator), the AP (proxy sensing initiator) may alternatively 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 measurement setup ID set in the AP includes the first ID, the second ID does not belong to the existing measurement setup ID set in the AP. Existing measurement setup IDs in the AP set 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 the measurement setup identifier used by the AP (proxy sensing initiator), the AP (proxy sensing initiator) may alternatively randomly select a value that is not the measurement setup identifier used by the AP (proxy sensing initiator) as the first measurement setup identifier. In other words, in this case, the first measurement setup identifier and the second measurement setup identifier may alternatively 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 a measurement instance 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 from belonging 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 for identifying the measurement setup parameters in <initiator MAC address, measurement setup ID> may be carried in a field such as a transmitter address (TA) or a source address (SA) of the transmitted PPDU. However, for a sensing responder (e.g., STA3), the initiator's MAC address may be carried in a field such as a receiver address (RA) or a 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. Although the MAC address is used herein to participate in distinguishing measurement setups, it should be further understood that some or all of the MAC address may be transmitted during transmission, but not necessarily all of the MAC address. This also applies hereinafter, and therefore the details will not be described again.

[0165] Embodiment 2 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 FIG. 3. This method mainly provides an explanation that the measurement setup ID set in the proxy sensing procedure may belong to an existing measurement setup ID set in the AP. Whether the measurement setup ID set in the proxy sensing procedure may belong to an existing measurement setup ID set is determined based on whether the corresponding measurement setup parameters are consistent. As shown in FIG. 6, the measurement setup identifier determination method includes, but is not limited to, the following steps:

[0166] S201: A proxy sensing initiator (AP) obtains first measurement setup parameters, where the first measurement setup parameters include parameters used by the proxy sensing initiator and a sensing responder in a proxy sensing procedure.

[0167] Optionally, for the 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 FIG. 5), and the details will not be described again here.

[0168] S202: The proxy sensing initiator (AP) sends 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 identifying 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 identifying 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 the measurement setup identifier 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 (denoted as a first measurement setup identifier) ​​for the first measurement setup parameter, where the measurement setup identifier identifies the first measurement setup parameter. Specifically, the AP (proxy sensing initiator) may detect whether a measurement setup identifier identifying the same measurement setup parameter as the first measurement setup parameter exists in the first identifier set (i.e., the measurement setup identifier set used by the proxy sensing initiator (AP)). If a third measurement setup identifier identifying 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 in the first identifier set as the first measurement setup identifier. In other words, if the measurement setup parameter identified by the third measurement setup identifier in the first identifier set is the same as the first measurement setup parameter, 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. If there is no measurement setup identifier in the first identifier set that identifies the same measurement setup parameter as the first measurement setup parameter, 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 there is no measurement setup identifier in the first identifier set that identifies the same measurement setup parameter as the first measurement setup parameter, 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 (AP).The measurement setup identifier used by the AP (proxy sensing initiator) may include a measurement setup identifier used by the AP (proxy sensing initiator) in a sensing procedure (here, a non-proxy sensing procedure) and / or a 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 may use an existing measurement setup ID in the AP to identify the measurement setup. Whether the existing measurement setup ID in the AP can identify the measurement setup depends on whether the parameters corresponding to the existing measurement setup ID between the AP (proxy sensing initiator) and the sensing responder (e.g., STA3) match the parameters (here, the first measurement setup parameters) corresponding to the measurement setup that the requesting STA (e.g., STA1) wants to establish. If the parameters corresponding to the existing measurement setup ID between the AP (proxy sensing initiator) and the sensing responder (e.g., STA3) match the parameters (here, the first measurement setup parameters) corresponding to the measurement setup that the requesting STA (e.g., STA1) wants to establish, the existing measurement setup ID in the AP can be reused. If the parameters corresponding to the existing measurement setup ID between the AP (proxy sensing initiator) and the sensing responder (e.g., STA3) do not match the parameters (here, the first measurement setup parameters) corresponding to the measurement setup that the requesting STA (e.g., STA1) wants to establish, a new number is created to identify a new measurement setup. The existing measurement setup IDs in the AP include an established measurement setup ID set by the AP as the initiator in a proxy sensing procedure and an established measurement setup ID set by the AP as the initiator in a non-proxy sensing procedure.

[0171] Optionally, after setting the first measurement setup identifier for the first measurement setup parameter, the AP (proxy sensing initiator) may send a piece of information (denoted as first information) including the first measurement setup parameter and the first measurement setup identifier to the sensing responder (e.g., STA3 in FIG. 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) may 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 a subsequent sensing measurement procedure.

[0172] Optionally, when the requesting STA configures a second measurement setup identifier for the first measurement setup parameters and notifies the AP (proxy sensing initiator), a mapping relationship may exist in the AP (proxy sensing initiator), specifically, the first measurement setup identifier corresponds to the second measurement setup identifier. 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.

[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) sending third information to the sensing responder (e.g., STA3 in FIG. 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 parameter 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, the third information may further carry part of the parameters in the first measurement setup parameter, 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 sending 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 the following steps, but is not limited thereto.

[0178] S301: A proxy sensing initiator (AP) obtains first measurement setup parameters, where the first measurement setup parameters include parameters used by the proxy sensing initiator and a sensing responder in a proxy sensing procedure.

[0179] Optionally, for the 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 FIG. 5), and the details will not be described again here.

[0180] S302: The proxy sensing initiator (AP) sends first information to the sensing responder (STA3), where the first information includes first measurement setup parameters, a 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 by using the first information belongs to a proxy sensing procedure.

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

[0182] Optionally, after setting the first measurement setup identifier for the first measurement setup parameter and obtaining the fourth information, the AP (proxy sensing initiator) may send a piece of information (denoted as the first information) including the first measurement setup parameter, the first measurement setup identifier, and the fourth information to a sensing responder (e.g., STA3 in FIG. 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, so that the first measurement setup parameter can be uniquely indexed by using the first measurement setup identifier and the fourth information in a subsequent sensing measurement procedure.

[0183] In other words, when the AP functioning as a proxy sends 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 information related to the requesting STA (STA1) (e.g., AID, UID, the MAC address and virtual number of STA1 (the virtual number corresponds to the requesting STA)), and / or the information related to proxy sensing (e.g., this may indicate that the measurement setup belongs to the measurement setup in the proxy sensing procedure). Since the information related to the requesting STA and the information related to proxy sensing 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 information related to the requesting STA 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, step S302Then, the measurement setup method in the proxy sensing procedure may further include: the proxy sensing initiator (AP) sends third information to the sensing responder (e.g., STA3 in FIG. 3 ), where the third information includes the first measurement setup identifier and the fourth information. In other words, the method in which the AP (proxy sensing initiator) sends a measurement setup ID carrying the fourth information in the proxy sensing procedure 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 and the fourth information, the third information may further carry some of the first measurement setup parameters, such as bandwidth.

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

[0187] In this embodiment of the present application, when sending a measurement setup ID in a proxy sensing procedure, the proxy sensing initiator (AP) carries information for identifying the requesting STA and / or information indicating that the established measurement setup belongs to the proxy sensing procedure, to help the sensing responder (STA3) distinguish between different measurement setups. From another perspective, 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 content describes in detail the method provided in the present application. To facilitate the implementation of the above solutions in the embodiments of the present application, the embodiments of the present application further provide a corresponding apparatus or device.

[0189] In an embodiment of the present application, the proxy sensing initiator (AP) may be divided into functional modules based on the above-described method. For example, each functional module may be obtained by dividing the functional modules based on their corresponding functions, or two or more functions may be integrated into one processing module. The integrated module may be implemented in the form of hardware or in the form of a software functional module. It should be noted that in the embodiment of the present application, the division into modules is merely an example and represents a logical functional division. In actual implementation, other division methods may be used. Hereinafter, a communication device in an embodiment of the present application will be described in detail with reference to FIGS. 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 in the proxy sensing initiator (AP), for example a Wi-Fi chip. As shown in Figure 8, the communication device includes an acquisition module 11 and a transceiver module 12.

[0191] 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 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 parameters and a first measurement setup identifier, where the first measurement setup identifier identifies the first measurement setup parameters, and the first measurement setup identifier is different from the measurement setup identifier used by the proxy sensing initiator.

[0192] Optionally, the acquisition module 11 includes a receiving unit 111 and a determining unit 112. The receiving unit 111 is configured to receive second information sent by the requesting station STA, where the second information includes second measurement setup parameters, and the second measurement setup parameters include all or part of parameters used by the proxy sensing initiator and the sensing responder in the proxy sensing procedure. The determining unit 112 is configured to determine first measurement setup parameters based on the second measurement setup parameters.

[0193] Optionally, the receiving unit 111 in the acquisition module 11 is configured to receive second information sent by the requesting STA, where the second information includes first measurement setup parameters.

[0194] Optionally, the second information further includes a second measurement setup identifier, where the second measurement setup identifier corresponds to the first measurement setup identifier.

[0195] Optionally, the second measurement setup identifier is not the measurement setup identifier used by the proxy sensing initiator, and the first measurement setup identifier is the same as the second measurement setup identifier.

[0196] Optionally, the measurement setup identifier used by the proxy sensing initiator includes a measurement setup identifier used by the proxy sensing sender in the sensing procedure and a measurement setup identifier used by the proxy sensing sender in the proxy sensing procedure.

[0197] Optionally, the transceiver module 12 is further configured to transmit third information to the sensing responder, where the third information includes the first measurement setup identifier.

[0198] The acquisition module 11 may also be called a processing module.

[0199] It should be understood that the communication device in this design may correspondingly implement embodiment 1, and the above operations or functions of the units in the communication device are respectively used to implement the corresponding operations of the proxy sensing initiator (AP) in embodiment 1. For brevity, the details will not be described again here.

[0200] 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 the sensing responder in a 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 parameters and a first measurement setup identifier, where the first measurement setup identifier identifies the first measurement setup parameter. If a third measurement setup identifier identifying 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 the first measurement setup identifier does not belong to the first identifier set, or if no measurement setup identifier identifying 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. The first identifier set includes the measurement setup identifier used by the proxy sensing initiator.

[0201] Optionally, the acquisition module 11 includes a receiving unit 111 and a determining unit 112.

[0202] Optionally, the receiving unit 111 in the acquisition module 11 is configured to receive second information sent by the requesting STA, where the second information includes first measurement setup parameters.

[0203] Optionally, the second information further includes a second measurement setup identifier, where the second measurement setup identifier corresponds to the first measurement setup identifier.

[0204] Optionally, the measurement setup identifier used by the proxy sensing initiator includes a measurement setup identifier used by the proxy sensing sender in the sensing procedure and a measurement setup identifier used by the proxy sensing sender in the proxy sensing procedure.

[0205] Optionally, the transceiver module 12 is further configured to transmit third information to the sensing responder, where the third information includes the first measurement setup identifier.

[0206] The acquisition module 11 may also be called a processing module.

[0207] It should be understood that the communication device in this design may correspondingly perform embodiment 2, and the above operations or functions of the units in the communication device are respectively used to implement the corresponding operations of the proxy sensing initiator (AP) in embodiment 2. For brevity, the details will not be described 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 the sensing responder in a proxy sensing procedure. The transceiver module 12 is configured to send first information to the sensing responder, where the first information includes the first measurement setup parameters, a 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 a requesting STA and / or information indicating that the measurement setup requested to be established by using the first information belongs to a proxy sensing procedure.

[0209] Optionally, the information for identifying the requesting STA includes one or more of the following: an identifier of the requesting STA, part or all of the media access control MAC address of the requesting STA, and one or more of 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.

[0210] Optionally, the acquisition module 11 includes a receiving unit 111 and a determining unit 112. The receiving unit 111 is configured to receive second information sent by the requesting station STA, where the second information includes second measurement setup parameters, and the second measurement setup parameters include all or part of parameters used by the proxy sensing initiator and the sensing responder in the proxy sensing procedure. The determining unit 112 is configured to determine first measurement setup parameters based on the second measurement setup parameters.

It should be understood that any product in any form having the functionality of the proxy sensing initiator (AP) in FIG. 8 falls within the scope of protection of the embodiments of the present application. It should be further understood 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 the present application.

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

[0218] For convenience of explanation, please refer to Fig. 9. Fig. 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 the proxy sensing initiator (AP). Fig. 9 shows only the main components of the communication device 1000.
