[0060] To make the objectives, technical solutions, and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings. Exemplary embodiments will be described in detail herein, with examples shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0061] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0062] It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining."

[0063] First, some terms involved in the embodiments of this application are introduced as follows:

[0064] Association Identifier (AID): used to identify a terminal after establishing an association with an access point.

[0065] WLAN Sensing: This technology detects people and objects in the environment by measuring changes in WLAN signal scattering and / or reflection caused by people and objects. In other words, WLAN sensing uses wireless signals to measure and perceive the surrounding environment, enabling functions such as indoor intrusion, movement, and fall detection, gesture recognition, and spatial 3D image creation.

[0066] Proxy Sensing Measurement: This refers to a sensing measurement device requesting a sensing measurement device other than itself to perform sensing measurements on its behalf. For example, an access point (AP) requests a station (STA) to perform sensing measurements on its behalf, or a STA requests an AP to perform sensing measurements on its behalf.

[0067] WLAN devices participating in WLAN awareness may have the following roles:

[0068] Sensing Initiator: A device that initiates sensing measurements and wants to obtain sensing results.

[0069] Sensing Responder: a device that participates in sensing measurements other than the sensing initiator.

[0070] Sensing Transmitter (also known as Sensing Transmitter), a device that sends a Sensing Illumination Signal.

[0071] Sensing Receiver, also known as sensing receiver, is a device that receives sensing measurement signals.

[0072] Sensing by Proxy Initiator (also known as a proxy requester) is a device that requests other devices to initiate sensing measurements.

[0073] The Sensing by Proxy Responder, also known as the Sensing Proxy STA or Sensing Proxy Responder, is a device that responds to requests from the Proxy Initiator and initiates sensing measurements.

[0074] A WLAN terminal may have one or more roles in a perception measurement. For example, a perception initiating device may be only a perception initiating device, a perception signal sending device, a perception signal receiving device, or both a perception signal sending device and a perception signal receiving device.

[0075] Next, the relevant technical background involved in the embodiments of this application is introduced:

[0076] Figure 1 shows a block diagram of a perception measurement system provided by an exemplary embodiment of the present application. The perception measurement system includes terminals, terminals, network devices, or access points (APs) and STAs, though this application does not limit this. This application uses the perception measurement system including APs and STAs as an example for illustration.

[0077] In some scenarios, an AP can be referred to as an AP STA, meaning that in a sense, an AP is also a type of STA. In some scenarios, a STA can be referred to as a non-AP STA.

[0078] In some embodiments, STAs may include AP STAs and non-AP STAs.

[0079] Communication in a communication system can be between an AP and a non-AP STA, between a non-AP STA and a non-AP STA, or between a STA and a peer STA. A peer STA refers to a device that communicates with the STA peer. For example, a peer STA may be an AP or a non-AP STA.

[0080] An AP acts as a bridge between wired and wireless networks, connecting wireless network clients together and then connecting the wireless network to the Ethernet. An AP can be a terminal device (such as a mobile phone) or a network device (such as a router) equipped with a Wireless Fidelity (Wi-Fi) chip.

[0081] It should be understood that the role of STA in the communication system is not absolute. For example, in some scenarios, when a mobile phone is connected to a router, the mobile phone is a non-AP STA. When the mobile phone serves as a hotspot for other mobile phones, the mobile phone plays the role of AP.

[0082] APs and non-AP STAs can be devices used in the Internet of Vehicles, IoT nodes and sensors in the Internet of Things (IoT), smart cameras, smart remote controls, smart water and electricity meters in smart homes, and sensors in smart cities.

[0083] In some embodiments, non-AP STAs may support, but are not limited to, 802.11be. Non-AP STAs may also support various current and future 802.11 family WLAN standards, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0084] In some embodiments, the AP may be a device supporting the 802.11be standard. The AP may also be a device supporting various current and future 802.11 family WLAN standards, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0085] In the embodiment of the present application, the STA may be a mobile phone, tablet computer, computer, virtual reality (VR) device, augmented reality (AR) device, wireless device in industrial control, set-top box, wireless device in self-driving, in-vehicle communication equipment, wireless device in remote medical care, wireless device in smart grid, wireless device in transportation safety, wireless device in smart city, wireless device in smart home, wireless communication chip / ASIC / SOC / etc. that supports WLAN / Wi-Fi technology.

[0086] WLAN technology can support frequency bands including but not limited to: low frequency bands (2.4GHz, 5GHz, 6GHz) and high frequency bands (60GHz).

[0087] One or more links exist between a station and an access point.

[0088] In some embodiments, stations and access points support multi-band communications, for example, communicating simultaneously on the 2.4 GHz, 5 GHz, 6 GHz, and 60 GHz frequency bands, or communicating simultaneously on different channels within the same frequency band (or different frequency bands), thereby improving the communication throughput and / or reliability between devices. Such devices are generally referred to as multi-band devices, or multi-link devices (MLDs), and are sometimes also referred to as multi-link entities or multi-band entities. A multi-link device can be an access point device or a station device. If the multi-link device is an access point device, the multi-link device includes one or more APs; if the multi-link device is a station device, the multi-link device includes one or more non-AP STAs.

[0089] A multi-link device including one or more APs is called an AP, and a multi-link device including one or more non-AP STAs is called a Non-AP. In the embodiment of the application, the Non-AP can be called a STA.

[0090] In an embodiment of the present application, the AP may include multiple APs, the Non-AP may include multiple STAs, multiple links may be formed between the APs in the AP and the STAs in the Non-AP, and data communication may be performed between the APs in the AP and the corresponding STAs in the Non-AP through the corresponding links.

[0091] An AP is a device deployed in a wireless local area network to provide wireless communication capabilities for STAs. A station may include: User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless communication device, a user agent, or a user device. Optionally, a station may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, or a wearable device, but the embodiments of the present application are not limited to this.

[0092] In the embodiment of the present application, both the station and the access point support the IEEE 802.11 standard.

[0093] In a WLAN awareness scenario, WLAN terminals participating in awareness include: an awareness session initiating device and an awareness session responding device. Alternatively, WLAN terminals participating in awareness include: an awareness signal transmitting device and an awareness signal receiving device. The awareness session initiating device can be referred to as the awareness initiating device, and the awareness session responding device can be referred to as the awareness responding device.

[0094] Perception measurement can be applied to cellular network communication systems, wireless local area networks (WLAN) systems, or wireless fidelity networks (Wi-Fi) systems, and this application does not limit this. This application uses the application of perception measurement in WLAN or Wi-Fi systems as an example for schematic illustration.

[0095] (1) to (6) of FIG2 illustrate six typical scenarios of performing perception measurements based on perception signals provided by an exemplary embodiment of the present application.

[0096] In an exemplary embodiment, the sensing measurement may be a one-way interactive process in which one station sends a sensing signal to another station. As shown in (1) of FIG2 , the sensing measurement is a process in which station 2 sends a sensing signal to station 1.

[0097] In an exemplary embodiment, the perception measurement may be an interactive process between two stations. As shown in (2) of FIG2 , the perception measurement is that station 1 sends a perception signal to station 2, and station 2 sends a measurement result to station 1.

[0098] In an exemplary embodiment, the perception measurement may be a combination of multiple one-way information exchange processes. As shown in (3) of FIG2 , the perception measurement is that station 3 sends a perception signal to station 2, and station 2 sends a measurement configuration to station 1.

[0099] In an exemplary embodiment, the perception measurement may be that multiple stations send perception signals to the same station respectively. As shown in (4) of Figure 2 , the perception measurement is that station 2 and station 3 send perception signals to station 1 respectively.

[0100] In an exemplary embodiment, a sensing measurement may be performed by a station interacting with multiple other stations. As shown in (5) of Figure 2 , the sensing measurement is performed by station 1 sending sensing signals to stations 2 and 3, and stations 2 and 3 sending measurement configurations to station 1.

[0101] In an exemplary embodiment, as shown in (6) of FIG2 , in the perception measurement, multiple stations (such as station 3 and station 4 ) respectively send perception signals to station 2 , and station 2 sends the measurement result to station 1 .

[0102] (1) to (4) of FIG3 illustrate four typical scenarios of performing perception measurements based on perception signals and reflected signals provided by an exemplary embodiment of the present application.

[0103] In an exemplary embodiment, as shown in (1) of FIG3 , a sensing signal emitted by station 1 hits a sensing object, the sensing object reflects the sensing signal, and station 1 receives the reflected signal.

[0104] In an exemplary embodiment, as shown in (2) of FIG3 , the sensing signal emitted by station 2 hits a sensing object, the sensing object reflects the sensing signal, and station 2 receives the reflected signal.

[0105] In an exemplary embodiment, as shown in (3) of FIG3 , the sensing signals respectively emitted by site 1 and site 2 both hit the sensing object, the sensing object reflects the sensing signals emitted by site 1 and site 2 respectively, site 1 and site 2 respectively receive the signals reflected by the sensing object, and site 2 sends the measurement result to site 1 (i.e., the measurement results are shared synchronously between the sites).

[0106] In an exemplary embodiment, as shown in (4) of FIG3 , the sensing signals respectively emitted by site 3 and site 2 both hit the sensing object, and the sensing object reflects the sensing signals emitted by site 3 and site 2 respectively. Site 3 and site 2 respectively receive the signals reflected by the sensing objects, and site 3 sends the measurement results to site 1 and site 2 respectively, and site 2 also sends the measurement results to site 1 (i.e., the measurement results are shared synchronously between the sites).

[0107] As shown in FIG4 , the WLAN sensing session includes one or more of the following phases: a sensing discovery phase 41 , a session establishment phase 42 , a sensing measurement phase 43 , a sensing reporting phase 44 , and a session termination phase 45 .

[0108] Perception discovery phase 41: used to initiate a perception session.

[0109] Session establishment phase 42: establishing a perception session, determining the perception session participants and their roles (including perception signal sending devices and perception signal receiving devices), determining the operating parameters related to the perception session, and optionally exchanging the parameters between terminals.

[0110] Perception measurement phase 43: Perception measurement is performed, and the perception signal sending device sends a perception signal to the perception signal receiving device.

[0111] Perception reporting phase 44: Reporting measurement results. Depending on the application scenario, the perception receiving device may need to report the measurement results to the perception measurement initiating device.

[0112] Session termination phase 45: The terminal stops measuring and terminates the sensing session.

[0113] The same perception measurement device may have one or more roles in a perception session. For example, the perception session initiating device can be only a perception session initiating device, or it can be a perception signal sending device, or it can be a perception signal receiving device, or it can be both a perception signal sending device and a perception signal receiving device.

[0114] The perception measurement process can be divided into at least two types: trigger-based (TB) perception measurement process and non-trigger-based (non-TB) perception measurement process. The non-trigger-based (non-TB) perception measurement process can also be called non-trigger-based (non-TB) perception measurement process.

[0115] TB-based perception measurement process:

[0116] 5 to 7 illustrate a measurement process based on a trigger frame, which includes three stages: a perception measurement setting stage (as shown in FIG5 ), a perception measurement stage (as shown in FIG6 ), and a perception reporting stage (as shown in FIG7 ).

[0117] As shown in Figure 5, in the perception measurement setting stage, the perception initiating device (such as AP) sends a perception measurement setting request frame to the perception response device 1 (such as STA1), the perception response device 2 (such as STA2), and the perception response device 3 (such as STA3) respectively, and the perception response device 1, the perception response device 2, and the perception response device 3 respectively feedback the perception measurement setting response frame to the perception initiating device.

[0118] As shown in Figure 6, the perception measurement phase is divided into three parts: measurement polling, uplink measurement, and downlink measurement:

[0119] In the measurement polling process, the sensing initiating device sends a sensing measurement polling trigger frame to sensing response device 1, sensing response device 2, and sensing response device 3 respectively. Sensing response device 1, sensing response device 2, and sensing response device 3 respond to the sensing measurement polling trigger frame to the sensing initiating device.

[0120] In the uplink measurement process, the perception initiating device sends a perception measurement trigger frame to perception response device 1, perception response device 2, and perception response device 3 respectively, and perception response device 1, perception response device 2, and perception response device 3 send a measurement frame (such as an NDP) to the perception initiating device.

[0121] In the downlink measurement process, the sensing initiating device sends a sensing measurement declaration frame to sensing response device 1, sensing response device 2, and sensing response device 3 respectively, and then sends a measurement frame (such as NDP) to sensing response device 1, sensing response device 2, and sensing response device 3 respectively.

[0122] The CTS-to-self in Figure 6 is a frame format defined in the relevant communication standards, and is used in this application to represent the response perception polling trigger frame.

[0123] As shown in Figure 7, the perception measurement reporting phase is divided into two parts: the reporting preparation process and the reporting process:

[0124] During the reporting preparation process, the perception initiating device sends a perception feedback request frame to perception response device 1, perception response device 2, and perception response device 3 respectively. Perception response device 1, perception response device 2, and perception response device 3 then feed back a perception feedback response frame to the perception initiating device.

[0125] During the reporting process, the perception initiating device sends a perception measurement reporting trigger frame to perception response device 1 and perception response device 2, respectively. Perception response devices 1 and 2 then feed back the perception measurement reporting frames to the perception initiating device. The perception initiating device sends a perception measurement reporting trigger frame to perception response device 3, and perception response device 3 feeds back the perception measurement reporting frame to the perception initiating device.

[0126] Perception measurement process based on Non-TB:

[0127] 8 and 9 illustrate a measurement process based on a non-trigger frame, which includes two stages: a perception measurement setting stage (as shown in FIG8 ) and a perception measurement reporting stage (as shown in FIG9 ).

[0128] As shown in FIG8 , in the perception measurement setting phase, the perception initiating device (such as an AP) sends a perception measurement setting request frame to the perception responding device (such as a STA), and the perception responding device feeds back a perception measurement setting response frame to the perception initiating device.

[0129] As shown in Figure 9, the perception measurement reporting phase is divided into three parts: forward measurement process, reverse measurement process, and measurement reporting process:

[0130] During the forward measurement process, the sensing initiator sends a sensing measurement announcement frame to the sensing responder, and then sends a measurement frame (such as NDP) to the sensing responder.

[0131] During the reverse measurement process, the sensing responding device sends a measurement frame (such as NDP) to the sensing initiating device.

[0132] During the measurement reporting process, the sensing initiating device sends a sensing feedback request frame to the sensing responding device, the sensing responding device sends a sensing feedback response frame to the sensing initiating device, and then the sensing responding device sends a sensing measurement reporting frame to the sensing initiating device.

[0133] Figure 10 shows a schematic diagram of the radio frequency (RF) and baseband (BB) modules of a Wi-Fi communication link, including a transmitter (Tx) and a receiver (Rx). In the order of transmitting signals, the transmitter contains a baseband, a digital-to-analog (D / A) converter (DAC), a mixer, a power amplifier (PA), and an antenna. In the order of receiving signals, the receiver contains an antenna, a low-noise amplifier (LNA), a mixer, a variable gain amplifier (VGA), a D / A converter, and a baseband. The low-noise amplifier and the VGA are used for automatic gain control (AGC).

[0134] Wi-Fi / WLAN sensing focuses on the physical channel between the transmitter antenna and the receiver antenna. This physical channel is affected by physical environments such as walls, floors, and moving objects. However, Wi-Fi / WLAN devices are designed to transmit data and are concerned with the relationship between baseband symbols sent by the transmitter and received by the receiver. Therefore, the channel sensed by their inherent channel estimation function is not just the physical channel, but a composite channel, encompassing both the transmitter's internal transmission link and the receiver's internal reception link. In other words, the composite channel is the complete link from the transmitter's baseband to the receiver's baseband. In the "Principles of Communication," this composite channel is also referred to as a modulation channel. Therefore, when using Wi-Fi / WLAN to sense changes in the physical environment, if the transmitter's transmit power and transmit antenna radiation pattern change during this period, or if the receiver's receive gain (i.e., the automatic gain control gain) and receive antenna radiation pattern change, this can interfere with the perception of the physical channel itself, reducing perception accuracy.

[0135] Based on the above problems, this application proposes an improvement plan based on the content of 11bf Draft 0.1, which modifies or newly defines several elements and frame formats in the setting, measurement, and reporting stages of perception measurement to transmit relevant information, so as to eliminate or compensate for the interference of changes in transmit power, changes in transmitting antenna radiation pattern, AGC receiving gain, and changes in receiving antenna radiation pattern on the perception measurement results.

[0136] FIG11 shows a flowchart of a perception measurement method provided by an exemplary embodiment of the present application. The method is performed by a perception initiator, a perception responder, a perception sender, or a perception receiver. The method includes at least one of the following steps:

[0137] Step 112: Carry target information in at least one frame in the sensing measurement process, where the target information is related to at least one of transmit power, receive AGC gain, transmit antenna radiation pattern, and receive antenna radiation pattern.

[0138] In some embodiments, the target information is used to eliminate or compensate for the impact of changes in at least one of transmit power, receive AGC gain, transmit antenna radiation pattern, and receive antenna radiation pattern on the perception measurement results.

[0139] In some embodiments, carrying target information in at least one frame during the perception measurement process includes at least one of the following steps:

[0140] Carrying target information in at least one frame during the perception measurement setup phase;

[0141] Carrying target information in at least one frame of the perception measurement phase;

[0142] Carry target information in at least one frame during the perception measurement reporting phase.

[0143] In some embodiments, the target information is carried in at least one frame between the physical (Physical, PHY) layer and the medium access control (MAC) layer for transmission. Optionally, at least one of the following steps is included:

[0144] The PHY layer configuration vector carried in the PHY layer configuration request primitive carries at least one of the following parameters:

[0145] AGC constraint parameters;

[0146] Receive antenna radiation pattern constraint parameters;

[0147] The receive vector passed from the PHY layer to the MAC layer carries the AGC gain parameter.

For example, the specific values ​​and meanings of this subfield are shown in Table 1.

[0203] Value meaning 0CSI1-255 reserved

[0204] · Transmit Power Constraint: Indicates whether the power of the NDP sent by the sensing sender in the sensing measurement instance associated with a sensing measurement setting ID should remain unchanged or change less than a first threshold.

[0208] I2R Tx Power CSI Compensation Mode: This field is reserved when the "Perception Receiver" subfield indicates that the perception responder is not a perception receiver. When the "Perception Receiver" subfield indicates that the perception responder is a perception receiver, this field indicates how to compensate for the impact of NDP transmit power changes on the I2R measured CSI in the perception measurement instance associated with a perception measurement setup ID.

[0209] In some embodiments, the compensation mode indicated by the I2R transmit power CSI compensation mode field includes any one of the following modes:

[0210] No compensation;

[0211] The sensing initiating device notifies the sensing responding device of the NDP transmit power, and the sensing responding device compensates the measured CSI based on the NDP transmit power.

[0212] The sensing initiating device stores the transmit power of the NDP and compensates the CSI sent by the sensing responding device based on the stored transmit power of the NDP.

[0213] For example, the specific values ​​and meanings of this field are shown in Table 2;

[0214] Table 2 Values ​​and meanings of I2R transmit power CSI compensation mode

[0215] Value meaning 0 No compensation 1 Sense responder transmit power CSI compensation 2 Sense initiator transmit power CSI compensation 3 Reserved

[0216] in,

[0217] 0 means no compensation: instructs the sensing initiator and the sensing responder not to perform transmit power CSI compensation;

[0218] 1 means CSI compensation of the sensing responder's transmit power: instructs the sensing initiator to inform the sensing responder of the transmit power used for each NDP, and the sensing responder compensates its calculated CSI based on the received transmit power;

[0219] 2 means CSI compensation of the sensing initiator's transmit power: instructs the sensing initiator to save the transmit power used for each NDP locally and compensate the CSI feedback it receives based on this transmit power;

[0220] 3 means the field is reserved.

[0221] R2I Tx Power CSI Compensation Mode: This field is reserved when the "Perception Sender" subfield indicates that the perception responder is not the perception sender. When the "Perception Sender" subfield indicates that the perception responder is the perception sender, this field indicates how to compensate for the impact of NDP transmit power changes on the CSI measured by R2I in the perception measurement instance associated with a perception measurement setup ID.

[0222] In some embodiments, the R2I transmit power CSI compensation mode field is used to indicate a compensation mode including any one of the following modes:

[0223] No compensation;

[0224] The sensing initiating device sends a specified transmit power of the NDP to the sensing responding device. The sensing responding device sends the NDP based on the specified transmit power. The sensing initiating device compensates the measured CSI based on the specified transmit power.

[0225] The sensing responding device informs the sensing initiating device of the NDP transmit power, and the sensing initiating device compensates the measured CSI based on the NDP transmit power.

[0226] For example, the specific values ​​and meanings of this field are shown in Table 3;

[0227] Table 3 Values ​​and meanings of R2I transmit power CSI compensation mode

[0228] Value meaning 0 No compensation 1 Perception initiator specifies R2I transmit power compensation 2 Perception responder feedback R2I transmit power compensation 3 Reserved

[0229] in,

[0230] 0 means no compensation: instructs the sensing initiator and the sensing responder not to perform R2I transmit power CSI compensation;

[0231] 1 means that the perception initiator specifies the R2I transmit power: the perception initiator explicitly informs the perception responder through the measurement announcement frame (NDP Announcement, NDPA) of the transmit power to be used for each NDP. The perception responder sends the NDP according to the transmit power specified by the perception initiator, and the perception initiator compensates the CSI calculated according to its specified transmit power.

[0232] In addition, in the perception measurement setting based on the trigger frame, this field cannot take the value of 1. The reason is that the protocol data unit (Physical Layer Protocol Data Unit, PPDU) used by the NDP in the R2I direction in the perception measurement based on the trigger frame is the TB PPDU, and the transmission of the TB PPDU already has an uplink transmit power control mechanism. The uplink target receive power (UL Target Receive Power) field exists in each user information (User Info) of the trigger frame, so that the receive power of multiple TB PPDUs received by the perception receiving device (such as AP) is similar, thereby facilitating demodulation by the perception receiving device. Therefore, it is contradictory to specify the transmit power of the perception sending device (such as STA) based on the existing UL TB PPDU power control.

[0233] 2 indicates that the sensing responder feeds back the R2I transmit power: the sensing responder reports the transmit power of the NDP to the sensing initiator, and the sensing initiator compensates the CSI calculated based on the received R2I NDP transmit power and the reference CSI.

[0234] 3 means the field is reserved.

[0235] AGC Gain CSI Compensation Mode: This field is reserved when the "Perception Receiver" subfield indicates that the perception responder is not a perception receiver. When the "Perception Receiver" subfield indicates that the perception responder is a perception receiver, this field indicates how to compensate for the impact of the perception responder's AGC gain variation on the CSI measured by the I2R NDP in the perception measurement instance associated with a perception measurement setup ID.

[0236] In some embodiments, the AGC gain CSI compensation mode field is used to indicate any one of the following compensation modes:

[0237] No compensation;

[0238] The sensor response device compensates the measured CSI based on the AGC gain used when receiving the NDP;

[0239] The sensing responding device sends the AGC gain used when receiving the NDP to the sensing initiating device. The sensing initiating device compensates the measured CSI based on the AGC gain and the reference CSI.

[0240] For example, the specific values ​​and their meanings are shown in Table 4;

[0241] Table 4 Values ​​and meanings of AGC gain CSI compensation mode

[0242] Value meaning 0 No compensation 1 Sense responder AGC gain CSI compensation 2 Sense initiator AGC gain CSI compensation 3 Reserved

[0243] in,

[0244] 0 means no compensation: indicates that neither the sensing initiator nor the sensing responder performs AGC gain CSI compensation;

[0245] 1 means AGC gain CSI compensation of the sensing responder: the sensing responder compensates its calculated CSI according to the AGC gain used when it receives the NDP;

[0246] 2 indicates AGC gain CSI compensation of the perception initiator: the perception responder feeds back the AGC gain used when receiving the NDP to the perception initiator through the perception measurement report frame. The perception initiator compensates the CSI it receives based on this AGC gain and the reference CSI.

[0247] 3 means the field is reserved.

[0350] Value meaning 04182163-7 reserved

[0351] The numerical values ​​in Table 12 are merely exemplary and may be set to other values ​​as long as the value corresponding to each grouping factor is different from the values ​​of other grouping factors.

[0352] R2I Tx Power: This is the second R2I transmit power. In the same perception measurement parameter element of the same perception measurement setting ID, if the value of "R2I Tx Power CSI Compensation Mode" is 0, 1, or 3, this field is reserved; if the value of "R2I Tx Power CSI Compensation Mode" is 2, this field indicates the transmit power of the R2I NDP in the perception measurement instance associated with a perception measurement instance ID or the transmit power of the R2I NDP associated with a set of reference CSI. For example, the values ​​and meanings of this field are shown in Table 13.

[0354] Value meaning 0-20dBm 1-19dBm...5939dBm6040dBm61~255 reserved

[0355] AGC Gain Level: In the perception measurement parameter element of the same perception measurement setting ID, if the value of "AGC Gain CSI Compensation Mode" is 0, 1, or 3, this field is reserved; if the value of "AGC Gain CSI Compensation Mode" is 2, this field indicates the AGC gain used by the perception response device when receiving the NDP in the perception measurement instance associated with a perception measurement instance ID, or the NDP reception AGC gain associated with a set of reference CSI. For example, the values ​​and meanings of this field are shown in Table 14.

[0357] Value meaning 0-20dB 1-19dB ... 7959dB 8060dB 81~255 reserved

[0358] Reference CSI Type: In the same perception measurement parameter element of the same perception measurement setting ID, if the value of "R2I transmit power CSI compensation mode" is 0, 1, or 3 and the value of "AGC gain CSI compensation mode" is 0, 1, or 3, this field is reserved. Otherwise, the values ​​and meanings of this field are shown in Table 15.

[0359] Table 15 Reference CSI Type Field Values ​​and Meanings

[0360] Value Meaning 0 Measured CSI1 Reference CSI related to R2I transmit power 2 Reference CSI related to AGC gain 3 Reserved

[0361] in,

[0362] 0 indicates measured CSI: indicates that the data carried by the "Perception Measurement Report" field in the perception measurement report element is CSI data obtained by real-time measurement, that is, CSI data measured based on NDP in the perception measurement instance associated with a perception measurement instance ID;

[0363] 1 represents reference CSI related to R2I transmit power: This indicates that the data carried in the "Perception Measurement Report" field in this Perception Measurement Report element is a set of reference CSI data, used by the Perception Initiator to implement R2I transmit power CSI compensation. This reference CSI is related to the transmit power of the R2I NDP sent by the Perception Responder. A set of reference CSI data corresponds to a transmit power level (indicated by the "R2I Transmit Power" field). This is fixed data pre-stored in the local cache of the Perception Responder, rather than CSI data measured in real time.

[0364] 2 represents reference CSI related to AGC gain: Indicates that the data carried by the "Perception Measurement Report" field in the perception measurement report element is a set of reference CSI data, which is used by the perception initiator to implement AGC gain CSI compensation. This reference CSI is related to the AGC gain level used by the perception responder when receiving the I2R NDP. A set of reference CSI data corresponds to one AGC gain level (indicated by the "AGC Gain" field). It is fixed data pre-stored in the local cache of the perception responder, rather than CSI data measured in real time;

[0365] 3 means the field is reserved.

[0366] It should be understood that the encoding format of the reference CSI data type is exactly the same as the measured CSI data type. The only difference is that the measured CSI data is the result data of a real perception measurement, while the reference CSI data is the reference data pre-configured by the perception response device. Its purpose is only to inform the perception initiator of the nonlinear frequency response characteristics of the R2I NDP transmit power to CSI and the nonlinear frequency response characteristics of the AGC to CSI in the perception response device, thereby assisting the perception initiator to complete R2I transmit power CSI compensation and AGC gain CSI compensation respectively.

[0367] When the value of the "Reference CSI Type" field is 1 or 2, in multiple perception measurement instances associated with the same perception measurement setting ID, the perception measurement report element in the perception measurement reporting frame of the first several perception measurement instances will only carry reference CSI data, that is, the value of the "Reference CSI Type" field in the perception measurement report element is 1 or 2. The specific number of perception measurement instances depends on the amount of reference CSI data pre-configured by the perception responder and is implementation-related. After the transmission of the reference CSI data is completed, the next perception measurement instance begins to carry the CSI data actually measured in the current perception measurement instance, that is, the value of the "Reference CSI Type" field in the perception measurement report element is 0.

[0368] Confidence: This indicates the receiver's confidence in the accuracy of the sensing measurement result. This parameter assists the initiator in evaluating and / or processing the sensing measurement result. The sensing measurement result can be CSI-related parameters or other parameters indicating channel characteristics or quality.

[0369] For example, the result of this perception measurement refers to CSI-related parameters. Since the confidence / confidence evaluation of the CSI measurement result is usually performed by the device that generates the CSI parameters (such as the perception receiver), if the device receiving the CSI measurement result (such as the perception initiator) uses the CSI measurement result for data transmission without knowing the accuracy or reliability of the CSI measurement result, it may have a negative impact on data transmission. Therefore, the confidence / confidence field facilitates the device receiving the perception measurement result (such as the perception initiator) to understand the accuracy or reliability of the perception measurement result, which is beneficial to subsequent perception measurement processes or other data transmission.

[0370] The method for estimating this confidence level is implementation dependent. There are multiple formats for this field.

[0371] In some embodiments, the format of this field is represented by at least one of a signed integer and an unsigned integer. In some embodiments, the multiple bits occupied by this field form multiple code points, and the multiple code points include a first part of code points and a second part of code points. Each code point in the first part of code points is used to indicate a confidence / confidence value, and the second part of code points is used to indicate whether the confidence / confidence value exists and / or is retained; in other embodiments, the multiple bits occupied by this field include a first part of bits and a second part of bits. The code point formed by the first part of bits is used to indicate the confidence / confidence value, and the second part of bits is used to indicate whether the confidence / confidence value exists. This embodiment of the present application is not limited to this.

[0372] For example, this field can be an 8-bit binary unsigned integer. Different values ​​represent different confidence levels. A larger value represents a greater confidence level. The valid value range of this field can be large or small. An example is shown in Table 16:

[0373] Table 16 Values ​​and meanings of the confidence level field

[0374] Value meaning 00% confidence / confidence 11% confidence / confidence 22% confidence / confidence ······9999% confidence / confidence 100100% confidence / confidence 101 Reserved 102 Reserved… 254 Reserved 255 Confidence / confidence does not exist

[0375] In this example, valid values ​​range from 0 to 100, representing 0% to 100% confidence.

[0376] In other examples, the valid value range may also be 0 to 254, representing a confidence level of 0% to 254%.

[0377] For example, this field can also be an 8-bit binary signed integer's complement. Different values ​​represent different confidence levels. A larger value represents a greater confidence level. The valid value range of this field can be large or small. An example is shown in Table 17:

[0378] Table 17 Values ​​and meanings of the confidence level field

[0379] Value meaning -128 confidence / confidence does not exist -127 -127% confidence / confidence

[0380] ...-2-2% confidence / confidence -1-1% confidence / confidence 00% confidence / confidence 11% confidence / confidence 22% confidence / confidence ... 126126% confidence / confidence 127127% confidence / confidence

[0381] In this example, valid values ​​range from -127 to 127, representing a confidence level of -127% to 127%, and a value of -128 represents no confidence level.

[0382] In other examples, the valid value range may also be -100 to 100, representing a confidence level of -100% to 100%, a value of -128 represents that the confidence level does not exist, and other values ​​indicate that the field is reserved.

[0383] Exemplarily, this field may also be an 8-bit binary signed integer's complement, and the meaning of its value is as shown in the following formula:

[0384]

[0385] Different values ​​represent different confidence levels. A larger value represents a greater confidence level. The valid range of values ​​for this field can be large or small. An example is shown in Table 18:

[0386] Table 18 Values ​​and meanings of the confidence level field

[0387] Value meaning -128 Confidence / Confidence does not exist -127 -31.75dB Confidence / Confidence -126 -31.5dB Confidence / Confidence ... -2 -0.5dB Confidence / Confidence -1 -0.25dB Confidence / Confidence 0 0dB Confidence / Confidence 10.25dB Confidence / Confidence 20.5dB Confidence / Confidence ... 126 31.5dB Confidence / Confidence 127 31.75dB Confidence / Confidence

[0388] In this example, the valid value range is -127 to 127, representing a confidence level of -31.75 dB to 31.75 dB, and a value of -128 represents no confidence level.

[0389] In other examples, the valid value range may also be -100 to 100, representing a confidence level of -31.75 dB to 31.75 dB, a value of -128 represents that the confidence level does not exist, and other values ​​indicate that the field is reserved.

[0390] Exemplarily, this field can also be a 2-byte 16-bit binary unsigned integer, or the complement of a 2-byte 16-bit binary signed integer, and the meaning and rules of its values ​​can be similar to Table 16, Table 17, or Table 18.

[0391] In some embodiments, the presence or absence of the confidence / confidence field can be indicated by an unused portion of the confidence / confidence field's value, or by a byte independent of the confidence / confidence field, or by a bit independent of the confidence / confidence field.

[0392] The values ​​and meanings of the above confidence / confidence fields are only for illustrative purposes and are not intended to limit this application.

[0393] The numbers below the fields in Figures 14 to 17 above represent the number of bits (Bits) or bytes (Octets) of the field.

[0394] In this application, the perceptual measurement methods can be classified into at least three categories according to the compensation mode, namely:

[0395] Type 1: I2R transmit power CSI compensation;

[0396] Type 2: R2I transmit power CSI compensation;

[0397] Type 3: AGC gain CSI compensation.

[0398] Type 1: I2R transmit power CSI compensation, using perception measurement based on non-triggered frames as an example

[0399] Method 1: No compensation

[0400] In this embodiment, the perception initiator and the perception responder are both perception senders and perception receivers, that is, both devices send and receive NDPs.

[0401] FIG18 shows a flowchart of a perception measurement method provided by an exemplary embodiment of the present application, which includes at least some of the following steps:

[0402] Step 181: The sensing initiator sends a sensing measurement setting request frame to the sensing responder;

[0403] The I2R transmit power CSI compensation mode value is 0, and the R2I transmit power CSI compensation mode value is 0, indicating that no transmit power CSI compensation is required for the I2R and R2I perception measurement results.

[0404] Step 182: The sensing responder sends a sensing measurement setting response frame to the sensing initiator;

[0405] Step 183: The sensing initiator sends a sensing measurement announcement frame to the sensing responder;

[0406] Step 184: The sensing initiator sends an I2R NDP to the sensing responder.

[0407] Step 185: The sensing responder sends an R2I NDP to the sensing initiator.

[0408] Step 186: The sensing initiator sends a sensing measurement reporting request frame to the sensing responder;

[0409] Step 187: The sensing responder sends a sensing measurement reporting response frame to the sensing initiator;

[0410] Step 188: The sensing responder sends a sensing measurement reporting frame to the sensing initiator. The CSI reported in the sensing measurement reporting frame is uncompensated CSI.

[0411] The method provided in this embodiment ensures the accuracy of the perception measurement results and reduces the waste of resources for CSI compensation by indicating in the "I2R Transmit Power CSI Compensation Mode" field that no I2R transmit power CSI compensation is required when the channel condition of the perception measurement system is good.

[0412] Method 2: CSI compensation of the responder's transmit power

[0413] In this embodiment, the perception initiator and the perception responder are both perception senders and perception receivers, that is, both devices send and receive NDPs.

[0414] FIG19 shows a flowchart of a perception measurement method provided by an exemplary embodiment of the present application, which includes at least some of the following steps:

[0415] Step 191: The sensing initiator sends a sensing measurement setting request frame to the sensing responder;

[0416] The I2R transmit power CSI compensation mode value is 1, and the R2I transmit power CSI compensation mode value is 0, indicating that the I2R perception measurement result needs to be "perceived responder transmit power CSI compensation", and the R2I perception measurement result does not need to be compensated.

[0417] Step 192: The sensing responder sends a sensing measurement setting response frame to the sensing initiator;

[0418] Step 193: The sensing initiator sends a sensing measurement announcement frame to the sensing responder;

[0419] The sensing initiator (sensing sender of I2R) sends a sensing measurement announcement frame to the sensing responder (sensing receiver of I2R) to indicate the transmit power of the I2R NDP in each sensing measurement instance. Exemplarily, the transmit power of the I2R NDP is 39 dBm.

[0420] Step 194: The sensing initiator sends an I2R NDP to the sensing responder.

[0421] The sensing responder compensates the CSI result based on the degree of change in the transmit power of the I2R NDP.

[0422] Step 195: The sensing responder sends an R2I NDP to the sensing initiator.

[0423] Step 196: The sensing initiator sends a sensing measurement reporting request frame to the sensing responder;

[0424] Step 197: The sensing responder sends a sensing measurement reporting response frame to the sensing initiator;

[0425] Step 198: The sensing responder sends a sensing measurement reporting frame to the sensing initiator. The CSI reported in the sensing measurement reporting frame is the CSI after compensation by the sensing responder.

[0426] The method provided in this embodiment improves the accuracy of the perception measurement results and ensures the normal operation of the perception measurement system by instructing the perception responder to perform I2R transmit power CSI compensation in the "I2R transmit power CSI compensation mode" field when there is path loss or attenuation in the perception measurement channel in the I2R direction, when the communication condition of the perception responder is better than that of the perception initiator, or the perception initiator is unable to perform CSI compensation.

[0427] Method 3: CSI compensation based on the transmit power of the initiator

[0428] In this embodiment, the perception initiator and the perception responder are both perception senders and perception receivers, that is, both devices send and receive NDPs.

[0429] FIG20 shows a flowchart of a perception measurement method provided by an exemplary embodiment of the present application, which includes at least some of the following steps:

[0430] Step 201: The sensing initiator sends a sensing measurement setting request frame to the sensing responder;

[0431] The I2R transmit power CSI compensation mode value is 2, and the R2I transmit power CSI compensation mode value is 0, indicating that the I2R perception measurement results need to be "perceived initiator transmit power CSI compensation", and the R2I perception measurement results do not need to be compensated.

[0432] Step 202: The sensing responder sends a sensing measurement setting response frame to the sensing initiator;

[0433] Step 203: The sensing initiator sends a sensing measurement announcement frame to the sensing responder;

[0434] Step 204: The sensing initiator sends an I2R NDP to the sensing responder;

[0435] The sensing initiator (the sensing sender of I2R) records the transmit power of the I2R NDP in each sensing measurement instance in a local cache. For example, the transmit power of the I2R NDP is 39 dBm.

[0436] Step 205: The sensing responder sends an R2I NDP to the sensing initiator;

[0437] Step 206: The sensing initiator sends a sensing measurement reporting request frame to the sensing responder;

[0438] Step 207: The sensing responder sends a sensing measurement reporting response frame to the sensing initiator;

[0439] Step 208: The sensing responder sends a sensing measurement reporting frame to the sensing initiator. The CSI reported in the sensing measurement reporting frame is uncompensated CSI. After the sensing initiator receives the sensing measurement reporting frame and uncompensated CSI from the sensing responder, it compensates the CSI based on the change in the buffered I2R NDP transmit power.

[0440] The method provided in this embodiment improves the accuracy of the perception measurement results and ensures the normal operation of the perception measurement system by instructing the perception initiator to perform I2R transmit power CSI compensation in the "I2R Transmit Power CSI Compensation Mode" field when there is path loss or attenuation in the perception measurement channel in the I2R direction, when the communication status of the perception initiator is better than that of the perception responder, or when the perception responder is unable to perform CSI compensation.

[0441] In summary, Type 1 in this application provides three I2R transmit power CSI compensation methods. By introducing the "I2R transmit power CSI compensation mode" field, the I2R transmit power CSI is flexibly compensated in different scenarios, eliminating the impact of NDP transmit power changes on the CSI obtained by I2R measurement, and improving the accuracy of the perceived measurement results.

[0442] Type 2: R2I transmit power CSI compensation, using the perception measurement based on non-triggered frames as an example

[0443] Method 1: No compensation

[0444] In this embodiment, the perception initiator and the perception responder are both perception senders and perception receivers, that is, both devices send and receive NDPs.

[0445] FIG21 shows a flowchart of a perception measurement method provided by an exemplary embodiment of the present application, which includes at least some of the following steps:

[0446] Step 211: The sensing initiator sends a sensing measurement setting request frame to the sensing responder;

[0447] The I2R transmit power CSI compensation mode value is 0, and the R2I transmit power CSI compensation mode value is 0, indicating that no transmit power CSI compensation is required for the I2R and R2I perception measurement results.

[0448] Step 212: The sensing responder sends a sensing measurement setting response frame to the sensing initiator;

[0449] Step 213: The sensing initiator sends a sensing measurement announcement frame to the sensing responder;

[0450] Step 214: The sensing initiator sends an I2R NDP to the sensing responder.

[0454] Step 218: The sensing responder sends a sensing measurement reporting frame to the sensing initiator. The CSI reported in the sensing measurement reporting frame is uncompensated CSI.

[0455] The method provided in this embodiment ensures the accuracy of the perception measurement results and reduces the waste of resources for CSI compensation by indicating in the "I2R Transmit Power CSI Compensation Mode" field that no I2R transmit power CSI compensation is required when the channel condition of the perception measurement system is good.

[0456] Method 2: Perception initiator specifies R2I transmit power CSI compensation

[0457] In this embodiment, the perception initiator and the perception responder are both perception senders and perception receivers, that is, both devices send and receive NDPs.

[0459] Step 221: The sensing initiator sends a sensing measurement setting request frame to the sensing responder;

[0460] The I2R transmit power CSI compensation mode value is 0, and the R2I transmit power CSI compensation mode value is 1, indicating that the I2R perception measurement result does not require transmit power CSI compensation, and the R2I perception measurement result requires "perception initiator specified R2I transmit power CSI compensation".

[0461] Step 222: The sensing responder sends a sensing measurement setting response frame to the sensing initiator;

[0462] Step 223: The sensing initiator sends a sensing measurement announcement frame to the sensing responder;

[0463] In each sensing measurement instance, the sensing initiator specifies the transmit power of the R2I NDP through a sensing measurement announcement frame and records the transmit power value of the R2I NDP in a local cache. For example, the transmit power of the R2I NDP is 39 dBm.

[0464] Step 224: The sensing initiator sends an I2R NDP to the sensing responder.

[0465] Step 225: The sensing responder sends an R2I NDP to the sensing initiator.

[0466] The sensing responder sends an R2I NDP to the sensing initiator according to the R2I NDP transmit power value specified by the sensing initiator in the sensing measurement announcement frame. The sensing receiver receives and obtains the CSI measurement results. After comparing them with the R2I NDP transmit power recorded in the local cache, the sensing initiator compensates the CSI based on the change in the R2I NDP transmit power.

[0467] The method provided in this embodiment improves the accuracy of the perception measurement results and ensures the normal operation of the perception measurement system by indicating in the "R2I Transmit Power CSI Compensation Mode" field that the perception measurement channel specified R2I transmit power CSI compensation is to be performed when there is path loss or attenuation in the R2I direction, when the communication status of the perception initiator is better than that of the perception responder, or when the perception responder is unable to perform CSI compensation.

[0468] Method 3: Perception responder feedback R2I transmit power CSI compensation

[0469] In this embodiment, the perception initiator and the perception responder are both perception senders and perception receivers, that is, both devices send and receive NDPs.

[0472] The I2R transmit power CSI compensation mode value is 0, and the R2I transmit power CSI compensation mode value is 2, indicating that the I2R perception measurement results do not require compensation, and the R2I perception measurement results require "perception responder feedback R2I transmit power CSI compensation."

[0473] Step 232: The sensing responder sends a sensing measurement setting response frame to the sensing initiator;

[0474] Step 233: The sensing initiator sends a sensing measurement announcement frame to the sensing responder;

[0475] Step 234: The sensing initiator sends an I2R NDP to the sensing responder.

[0476] Step 235: The sensing responder sends an R2I NDP to the sensing initiator.

[0477] The sensing initiator receives the R2I NDP and calculates the uncompensated CSI.

[0478] Step 236: The sensing initiator sends a sensing measurement reporting request frame to the sensing responder;

[0479] Step 237: The sensing responder sends a sensing measurement reporting response frame to the sensing initiator;

[0480] Step 238: The sensing responder sends a sensing measurement reporting frame to the sensing initiator. The sensing measurement reporting frame includes the transmit power of the R2I NDP. For example, the transmit power of the R2I NDP is 39 dBm.

[0481] The perception initiator compares the transmit power of the received R2I NDP with that of the R2I NDP fed back by the perception responder, and compensates the CSI calculated based on the degree of change in the transmit power of the R2I NDP.

[0482] The method provided in this embodiment improves the accuracy of the perception measurement results and ensures the normal operation of the perception measurement system by indicating in the "R2I transmit power CSI compensation mode" field that the perception responder feedback R2I transmit power CSI compensation when there is path loss or attenuation in the perception measurement channel in the R2I direction, and when the communication condition of the perception responder is better than that of the perception initiator, or the perception initiator is unable to perform CSI compensation. In summary, Type 2 in this application provides three R2I transmit power CSI compensation methods. By introducing the "R2I transmit power CSI compensation mode" field, the R2I transmit power CSI is flexibly compensated in different scenarios, eliminating the impact of NDP transmit power changes on the CSI obtained by R2I measurement, and improving the accuracy of the perception measurement results.

[0483] Type 3: AGC gain CSI compensation, using perceptual measurement based on non-trigger frames as an example

[0484] Since the impact and compensation of the R2I NDP's AGC gain change on CSI is an implementation issue within the perception initiator and is unrelated to the communication protocol, this type only considers the impact of I2R NDP's AGC gain CSI compensation on perception measurement results.

[0485] Method 1: No compensation

[0486] In this embodiment, the perception initiator and the perception responder are both perception senders and perception receivers, that is, both devices send and receive NDPs.

[0488] Step 241: The sensing initiator sends a sensing measurement setting request frame to the sensing responder;

[0489] The value of the AGC gain CSI compensation mode is 0, indicating that the perception measurement result of the I2R NDP does not require AGC gain CSI compensation.

[0498] Method 2: Perception responder AGC gain CSI compensation

[0499] In this embodiment, the perception initiator and the perception responder are both perception senders and perception receivers, that is, both devices send and receive NDPs.

[0500] FIG25 shows a flowchart of a perception measurement method provided by an exemplary embodiment of the present application, which includes at least some of the following steps:

[0501] Step 251: The sensing initiator sends a sensing measurement setting request frame to the sensing responder;

[0502] The value of the AGC gain CSI compensation mode is 1, indicating that the perception measurement result of the I2R NDP is subjected to “perception responder AGC gain CSI compensation”.

[0503] Step 252: The sensing responder sends a sensing measurement setting response frame to the sensing initiator;

[0504] Step 253: The sensing initiator sends a sensing measurement announcement frame to the sensing responder;

[0505] Step 254: The sensing initiator sends an I2R NDP to the sensing responder.

[0506] In each sensing measurement instance, the sensing responder records the AGC gain value when receiving the I2R NDP in a local buffer. For example, the AGC gain value is 60dB. Furthermore, the sensing responder performs CSI compensation based on the degree of change in the AGC gain.

[0507] Step 255: The sensing responder sends an R2I NDP to the sensing initiator.

[0508] Step 256: The sensing initiator sends a sensing measurement reporting request frame to the sensing responder;

[0509] Step 257: The sensing responder sends a sensing measurement reporting response frame to the sensing initiator;

[0510] Step 258: The sensing responder sends a sensing measurement reporting frame to the sensing initiator. The CSI reported in the sensing measurement reporting frame is the CSI after compensation by the sensing responder.

[0511] The method provided in this embodiment improves the accuracy of the perception measurement results and ensures the normal operation of the perception measurement system by indicating in the "AGC Gain CSI Compensation Mode" field that AGC gain CSI compensation of the perception responder is performed when there is path loss or attenuation in the perception measurement channel in the I2R direction, when the communication condition of the perception responder is better than that of the perception initiator, or the perception initiator is unable to perform CSI compensation.

[0512] Method 3: AGC gain CSI compensation of the perception initiator

[0513] In this embodiment, the perception initiator and the perception responder are both perception senders and perception receivers, that is, both devices send and receive NDPs.

[0514] FIG26 shows a flowchart of a perception measurement method provided by an exemplary embodiment of the present application, which includes at least some of the following steps:

[0515] Step 261: The sensing initiator sends a sensing measurement setting request frame to the sensing responder;

[0516] The value of the AGC gain CSI compensation mode is 2, indicating that the perception measurement result of the I2R NDP is “perceived initiator AGC gain CSI compensation”.

[0517] Step 262: The sensing responder sends a sensing measurement setting response frame to the sensing initiator;

[0518] Step 263: The sensing initiator sends a sensing measurement announcement frame to the sensing responder;

[0519] Step 264: The sensing initiator sends an I2R NDP to the sensing responder.

[0520] Step 265: The sensing responder sends an R2I NDP to the sensing initiator.

[0521] Step 266: The sensing initiator sends a sensing measurement reporting request frame to the sensing responder;

[0522] Step 267: The sensing responder sends a sensing measurement reporting response frame to the sensing initiator;

[0523] Step 268: The sensing responder sends a sensing measurement reporting frame to the sensing initiator. The sensing measurement reporting frame includes uncompensated CSI and the AGC gain value when the sensing responder receives the I2R NDP. Exemplarily, the AGC gain value when the sensing responder receives the I2R NDP is 60 dB.

[0524] The sensing initiator compensates the received uncompensated CSI according to the degree of change of the AGC gain.

[0525] The method provided in this embodiment improves the accuracy of the perception measurement results and ensures the normal operation of the perception measurement system by indicating in the "AGC Gain CSI Compensation Mode" field that AGC gain CSI compensation is performed for the perception initiator when there is path loss or attenuation in the perception measurement channel in the I2R direction and the communication status of the perception initiator is better than that of the perception responder, or the perception responder is unable to perform CSI compensation.

[0526] In summary, Type 3 in this application provides three AGC gain CSI compensation methods. By introducing the "AGC gain CSI compensation mode" field, CSI is flexibly compensated in different scenarios, eliminating the impact of AGC gain changes on the CSI measured by I2R NDP, and improving the accuracy of the perceived measurement results.

[0527] FIG27 shows a flowchart of a perception measurement method provided by an exemplary embodiment of the present application. This embodiment is described by taking the use of transmit power constraint in perception measurement based on non-triggered frames as an example. The method includes at least some of the following steps:

[0528] Step 271: The sensing initiator sends a sensing measurement setting request frame to the sensing responder;

[0529] Step 272: The sensing responder sends a sensing measurement setting response frame to the sensing initiator;

[0530] Step 273: The sensing initiator sends a sensing measurement announcement frame to the sensing responder;

[0531] Step 274: The sensing initiator sends an I2R NDP to the sensing responder.

[0532] Step 275: The sensing responder sends an R2I NDP to the sensing initiator.

[0533] Step 276: The sensing initiator sends a sensing measurement reporting request frame to the sensing responder;

[0534] Step 277: The sensing responder sends a sensing measurement reporting response frame to the sensing initiator;

[0535] Step 278: The sensing responder sends a sensing measurement reporting frame to the sensing initiator.

[0536] The sensing measurement setup request frame or the sensing measurement announcement frame carries a transmit power constraint field, and the transmit power constraint value is 1, indicating that the power of the sensing initiator sending the NDP is "transmitted power constrained." The sensing measurement report frame includes the constrained CSI.

[0537] In some embodiments, at least one of the "AGC gain constraint", "transmit antenna radiation pattern constraint", or "receive antenna radiation pattern constraint" fields may be carried in at least one frame in the perception measurement process for constraint.

[0538] Among them, the AGC gain constraint constrains the AGC gain of the perceptual receiver for receiving NDP by indication; the transmitting antenna radiation pattern constraint constrains the antenna radiation pattern used by the perceptual sender to send NDP by indication; and the receiving antenna radiation pattern constraint constrains the antenna radiation pattern used by the perceptual receiver to receive NDP by indication.

[0539] Those skilled in the art should understand the specific implementation of the above constraint method, which will not be described in detail in this application.

[0540] In summary, the method provided in this embodiment introduces the "transmit power constraint", "AGC gain constraint", "transmit antenna radiation pattern constraint", or "receive antenna radiation pattern constraint" fields to constrain the impact of transmit power changes, transmit antenna radiation pattern changes, AGC receive gain, and receive antenna radiation pattern changes on the perception measurement results, thereby improving the accuracy of the perception measurement results.
