Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method and apparatus for acquiring reference signal information. Background Technology

[0002] In Integrated Sensing and Communication (ISAC), dual-site sensing is an important sensing method for the sensing process. Dual-site sensing means that the transmission of sensing signals is performed by one site (such as a base station), while the reception and measurement of reflected sensing signals are performed by another node (such as the UE).

[0003] For the dual-site sensing mode of base station-terminal, the base station needs to configure sensing signals to the terminal, and the terminal performs sensing measurements based on the configured sensing signals. The sensing signals received by the terminal are reflected from the sensed object and reach the terminal. The signal strength is relatively weak. Therefore, the base station sending the sensing signal and the terminal are required to be close to each other so that the terminal can receive a sufficiently strong reflected signal, which is beneficial to the measurement of the sensing signal.

[0004] However, for indoor sensing scenarios, the base stations that configure sensing signals are usually deployed outdoors, which is far away from the indoor terminals. This results in weak sensing signals received by the terminals. Furthermore, the sensing signals are further weakened by being blocked by walls or glass, leading to low accuracy of the sensing measurement results. In severe cases, the intended sensing measurement tasks cannot be completed. Summary of the Invention

Detailed Implementation

[0035] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0036] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0037] The technical solutions provided in this application can be applied to various systems, especially 5G systems. For example, applicable systems may include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Long Term Evolution Advanced (LTE-A), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), and 5G New Radio (NR). All of these systems include terminal equipment and network equipment. The systems may also include a core network component, such as Evolved Packet System (EPS) and 5G systems (5GS).

[0038] First, let's introduce the following: (1) Basic concepts of Integrated Sensing and Communication (ISAC); The basic idea of ​​ISAC is to introduce wireless sensing functionality into wireless mobile communication. Wireless sensing refers to sensing environmental information through wireless signals. This environmental information includes the distribution, size, quantity, and temperature of objects in the environment, human actions and behaviors, and even human breathing rate and heart rate. The principle of wireless sensing is to transmit radio signals to the environment to be sensed, while simultaneously collecting the wireless signals reflected, scattered, and transmitted through multiple paths at the receiving end. Because the collected wireless signals are influenced by the environment, they carry environmental information. After receiving the signals, complex signal processing can be performed to obtain the characteristics of the environment, and the sensed environment can be reconstructed on a computer. This includes identifying people and objects in the environment, detecting temperature, detecting human movements, and even breathing and heart rate. It is used in fields such as personnel health monitoring and security.

[0039] Wireless sensing is generally divided into: monostatic sensing and dual-site sensing. Figure 1 This is a classification diagram of dual-station sensing and single-station sensing provided by related technologies, such as... Figure 1 As shown, single-site sensing includes: base station single-site sensing and terminal single-site sensing. Dual-site sensing includes: User Equipment (UE) - UE, Next Generation Node B (gNB) - gNB, UE - gNB, and gNB - UE. Single-site sensing refers to the base station (or terminal) actively sending sensing signals, which are then reflected by the object being sensed, and the base station (or terminal) receives the reflected sensing signals. Dual-site sensing refers to the base station (or terminal) actively sending sensing signals, which are then transmitted through a wireless channel and received by the terminal (or base station).

[0040] (2) The process of acquiring sensor signal resources; For dual-site sensing, when the sensing measurement is performed at the UE, the gNB needs to send the sensing measurement configuration to the UE; Figure 2 This is a flowchart illustrating the sensing and measurement process provided by related technologies, such as... Figure 2 As shown, it includes the following steps: Step 1: The terminal reports its sensing capabilities to the base station; Sensing capability reporting is used by the gNB to determine the UE's sensing capabilities and, based on those capabilities, to determine the UE's sensing configuration. UE sensing capabilities can be divided into sensing-related capabilities and UE radio capabilities. For example: UE perception capabilities: Supported perception measurement results, such as measuring departure angle / arrival angle and latency; Support for calculating perception results, such as target distance, speed, and angle; UE wireless capabilities: Supported bandwidth for transmitting / receiving signals, processing capabilities, etc.; Step 2: Sensing reference signal configuration; The base station, combining the capabilities reported by the UE and the quality requirements of the sensing service, determines the sensing reference signal resources (such as time domain information, frequency domain information, transmission power, etc.); and sends the configuration information of the sensing reference signal resources to the terminal.

[0041] Step 3: The base station sends a sensing reference signal; According to the information configured for the UE, the base station transmits sensing reference signals at a certain power on the corresponding frequency domain or time domain resources.

[0042] Step 4: Report the sensing measurement results; The terminal performs sensing measurements based on the resource configuration information of the sensing reference signal and reports the measurement results to the base station.

[0043] In current communication systems, most base stations are deployed outdoors. Although the standard supports the deployment of micro base stations indoors for indoor coverage, most indoor coverage still relies on the signal from outdoor base stations passing through walls or windows to enter the room.

[0044] Figure 3 This is a schematic diagram of a UE receiving a reference signal provided by related technologies, such as... Figure 3 As shown, for an indoor sensing scenario, if the sensing reference signal is emitted by an outdoor base station, the sensing mode is dual-station, that is, the base station sends the sensing reference signal (1), obtains the reference sensing signal (2) after passing through the wall, obtains the reference sensing signal (3) after being reflected by the sensed object, and the terminal receives the sensing reference signal. The path of the sensing reference signal is as follows: (1) The sensing signal is sent by the base station and reaches the wall after path attenuation.

[0045] (2) The signal passes through the wall to reach the room, and the signal experiences the penetration loss of the wall; at the same time, the signal reaches the object being sensed and experiences path attenuation.

[0046] (3) The signal is reflected by the object being sensed and reaches the receiving end UE.

[0047] Compared to outdoor scenarios, the sensing reference signal undergoes a wall penetration process, i.e., it experiences penetration loss, which further weakens the sensing signal received by the UE. Different wall materials have different penetration losses; the penetration loss values ​​for commonly used wall materials are shown in Table 1 below. Table 1: Penetration Loss Values ​​for Different Wall Materials

[0048] As shown in Table 1, the current building is made of concrete, and its penetration loss is about 17dB, which means that the signal is 17dB weaker than the outdoor sensing scene.

[0049] When a UE performs sensing reference signal measurements, the process of acquiring the sensing reference signal is configured by the base station where the UE is camped. Specifically, the base station first determines the transmission resource location of the sensing reference signal and instructs the UE on this resource location through a configuration message. When the base station is outdoors and the sensing scenario is indoors, especially when an indoor terminal receives a sensing reference signal transmitted from an outdoor base station, penetration loss weakens the sensing signal, leading to lower accuracy of the sensing measurement results. This prevents the UE from effectively completing the sensing measurement task.

[0050] This application provides a method and apparatus for acquiring reference signal information to improve the accuracy of sensing measurement results.

[0051] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0053] Figure 4 This is one of the flowcharts illustrating the method for obtaining reference signal information provided in the embodiments of this application, such as... Figure 4 As shown, the method for acquiring reference signal information is applied to a terminal, meaning the executing entity of this method is a terminal, such as a user equipment (UE). The steps of the method for acquiring reference signal information include: Step 400: Detect the reference signal sent by the first system device and obtain the reference signal information; Specifically, in order to avoid inaccurate sensing measurements due to weak sensing reference signals received by the terminal from the outdoor base station it is camped on, the terminal can autonomously search for sensing reference signals sent by other available devices. These other devices are different from the outdoor base station devices it is camped on.

[0054] Specifically, the terminal autonomously searches for available reference signals, i.e., the reference signals of the first system, such as gNBs of other operators deployed near or indoors with the example terminal, or WI-FI devices; the terminal can determine the reference signals that can be used for sensing based on the search results, and generate reference signal information, which is used to characterize one or more parameters of the reference signals of the first system detected by the terminal.

[0055] The reference signals for autonomous search can be: Wi-Fi signals, Long Term Evolution (LTE) signals, NR signals sent by other operator base stations, Bluetooth signals, and visible light signals, without any limitation.

[0056] It should be noted that the reference signal here refers to a known signal or channel data from the perspective of the terminal, including but not limited to: pilot signals, channel quality reference signals, beacon signals, broadcast data, etc.

[0057] Step 410: Send the reference signal information to the second system network-side device accessed by the terminal; The reference signal can be used for sensing measurements in the second system.

[0058] Specifically, after the terminal detects the reference signal from the first system and obtains the reference signal information, it can send the reference signal information to the network-side device of the second system so that the second system can perform sensing measurements. These sensing measurements include, but are not limited to: signal energy measurement, signal quality measurement, multipath delay measurement (e.g., for sensing the distance and position of the object being measured), Doppler frequency shift measurement (e.g., for sensing the scalar velocity and vector velocity of the object being measured), and signal angle of arrival measurement.

[0059] Figure 5 This is a deployment diagram of the perception scene provided in the embodiments of this application, such as... Figure 5 The sensing mode shown is a dual-site mode. The UE is located indoors, performing the sensing measurement task, and the object being sensed is also indoors. The gNB (second system network-side device) where the UE is camped is located outdoors, isolated from the UE by a wall. One or more WI-FI devices (first system devices) are deployed indoors. The terminal can detect the broadcast signal (reference signal) (1) sent by the WI-FI device. After being reflected by the object being sensed, the terminal obtains the broadcast signal (reference signal) (2). After detection, the terminal obtains the reference signal information and sends it to the gNB where the UE is camped.

[0060] Optionally, when configuring the sensing measurement signal (i.e., reference signal), the network-side equipment of the second system can configure the terminal to receive signals sent by other systems, such as the first system, and perform measurement tasks. This solves the problem of poor quality of sensing signals sent by the serving base station, improves sensing accuracy and user satisfaction, and reduces the radio resources consumed by the serving base station in sending sensing signals.

[0061] The reference signal information acquisition method provided in this application embodiment obtains reference signal information by actively probing the reference signal of the first system by the terminal, and sends the reference signal information of the first system to the network-side device of the second system accessed by the terminal for the second system to perform sensing measurement. This avoids the defect that the reference signal of the network-side device of the second system accessed by the terminal is weak when it arrives at the terminal, resulting in low accuracy of the sensing measurement results. It effectively improves the accuracy of the sensing measurement results and reduces the wireless resources spent by the network-side device of the second system accessed by the terminal to send sensing signals.

[0062] In some optional embodiments, the reference signal information includes one or more of the following: The standard information of the first system; The bandwidth information of the first system; Frequency band information of the first system; The network identification number of the first system; Quality information of the reference signal of the first system; The periodicity information of the reference signal of the first system.

[0063] Specifically, the parameters of the reference signal, i.e., the reference signal information, may include at least one of the following (a1)-(a6): (a1) The standard information of the first system may include one or more standard information of the first system; (a2) The bandwidth information of the first system may include the bandwidth information of one or more first systems; (a3) The frequency band information of the first system may include one or more frequency band information of the first system; or, it may include one or more bandwidth information of the first system and the corresponding frequency band information. (a4) The network identification number of the first system, such as: the Public Land Mobile Network (PLMN) of the communication system, or the Service Set Identifier (SSID) of Wi-Fi; (a5) Quality information of the reference signal of the first system, such as: Received Signal Strength Indication (RSSI) or Reference Signal Received Power (RSRP); (a6) The period information of the reference signal of the first system may specifically include the period value of the reference signal measurement.

[0064] Optionally, the quality information of the reference signal can be reported in absolute or relative terms, such as relative to the threshold value indicated by the base station or a preset reference value.

[0065] In one embodiment, the terminal performs reference signal detection for a first system and reports the reference signal information of the candidate first system to the base station. During the detection process, the terminal implements the detection itself. This can be done through the following two methods: Method 1: The terminal does not store the first system access information (such as the channel location and time information of the synchronization signal). The terminal first searches for synchronization signals, then reads broadcast information, and then obtains one or more available reference signal information (such as signal transmission period, frequency domain density, bandwidth), and measures the reference signals.

[0066] Method 2: The terminal stores the first system access information (such as the channel location of the synchronization signal, time information, and the receiving location of the broadcast signal). The terminal directly detects the broadcast control channel and receives scheduling information. Based on the scheduling information, it receives and reads the broadcast information, thereby obtaining one or more available reference signal information (such as signal transmission period, frequency domain density, bandwidth), and measures the reference signal.

[0067] The following is an example of the reporting command: (b1) Standard information for the first system: New Radio (NR).

[0068] Optionally, the version number of the standard can also be reported, such as NR rel-17 or NR rel-18.

[0069] (b2) Bandwidth and frequency band information of the first system: such as system bandwidth 400MHz; frequency band band n261; (b3) Network identification number of the first system: such as PLMN ID=46004 (b4) Quality information of the reference signal of the first system: Measured value of the received indication signal of the measurement signal: e.g., RSSI = -73dBm; (b5) Period information of the reference signal of the first system: such as 40ms.

[0070] Optionally, in the embodiments of this application, the bandwidth information of the first system reported by the terminal may refer to the channel bandwidth of the system communication or the signal bandwidth that can be used for sensing measurement, and different reporting methods may be used as needed.

[0071] Optionally, the quality information of the reference signal of the first system can be reported in absolute value (as shown in Table 2 below) or in relative value (such as the reporting threshold information relative to the reference signal information indicated by the base station) (as shown in Table 3 below).

[0072] Table 2: RSSI Measurement Reporting Mapping

[0073] As shown in Table 2, the terminal maps / quantizes the reported values ​​based on the RSSI values ​​of the measured sensing signals and the quantization relationship in Table 2.

[0074] Table 3: RSSI Measurement Reporting Mapping

[0075] Optionally, the value of threshold 1 is a threshold value indicated by the network-side device of the second system. It can also be specified by the protocol or obtained through other signaling configurations.

[0076] Optionally, the increment between adjacent reported values ​​in Table 3 is 1 dB, which is only an example and is not limited to this value. For example, it could be 1.5 dB, 2 dB, or 3 dB. In the future, to reflect flexibility, the increment can be different.

[0077] As shown in Table 3, the terminal maps or quantizes the reported values ​​based on the RSSI values ​​of the measured sensing signals and the quantization relationship in Table 3 above.

[0078] In one embodiment, the terminal performs reference signal detection for the first system and reports the reference signal information of the candidate first system to the network-side device of the second system. This detection process is based on the terminal's implementation.

[0079] The following is an example of a reporting command: (c1) System standard information: Wi-Fi; Optionally, the version number of the standard can also be reported, such as 802.11b or 802.11f.

[0080] (c2) Bandwidth and frequency band information of the first system: such as system bandwidth 160MHz; frequency band 6GHz; (c3) The network identification number of the first system: such as SSID=chinanet; (c4) Quality information of the reference signal of the first system: Measured value of the received indication signal of the measurement signal: e.g., RSSI = -73dBm; (c5) Period information of the reference signal of the first system: such as 200ms.

[0081] Optionally, in the embodiments of this application, the bandwidth information of the first system reported by the terminal may refer to the channel bandwidth of the system communication or the signal bandwidth that can be used for sensing measurement. Different reporting or definitions can be made according to the requirements.

[0082] Optionally, the quality information of the reference signal of the first system can be reported in absolute value (as shown in Table 2 above) or in relative value (as shown in Table 3 above).

[0083] Alternatively, for a Wi-Fi system, the terminal can receive a Wi-Fi signal in the following situations: Type A information: Only beacon signals can be received. Since beacon signals are unencrypted signals broadcast by Wi-Fi, all terminals can receive them, regardless of whether the Wi-Fi access point is legitimate or illegitimate.

[0084] Type B information: Other signals transmitted by the Wi-Fi; For legitimate users of the Wi-Fi (e.g., users who know the Wi-Fi password and can communicate with the Wi-Fi), in addition to reading the beacon signal, data communication-related or other control information can be further read. Compared with Type A information, Type B information can provide more reference signals for candidate first systems.

[0085] Type C information: In the evolved version of Wi-Fi, it can support sensing functions and the transmission of sensing signals. At this time, the terminal can receive the sensing signals sent by Wi-Fi and perform sensing measurements. That is, the terminal can use the reference signal of Wi-Fi to perform sensing services and measurements.

[0086] In order to facilitate the execution of the sensing tasks issued by the network-side equipment of the second system, the terminal can report one or more of the above-mentioned Class A information, Class B information or Class C information, so that the second system can make a decision on the network-side equipment to determine the reference signal.

[0087] In some optional embodiments, the first system includes one or more of the following: Wi-Fi systems, Bluetooth systems, and communication systems of operators that differ from the second system.

[0088] Specifically, the first system can be understood as a system different from the system where the terminal resides. For example, if the terminal resides in the NR-1 system of operator A, the first system can be the NR-2 system of operator B, or the LTE system, the WI-FI system, etc.

[0089] Optionally, the first system may also be referred to as a different system, or other systems relative to the system currently accessed by the terminal. This application embodiment does not limit this.

[0090] In some optional embodiments, the method further includes: The terminal sends sensing and measurement capability information to the network-side device of the second system, the sensing and measurement capability information including the terminal's sensing and measurement capability of the first system.

[0091] Specifically, the terminal can report its capabilities to the network side device of the second system in advance, that is, send the terminal's perception and measurement capability information to the network side device of the second system, such as reporting the terminal's perception and measurement capabilities of the first system.

[0092] Optionally, the terminal may report sensing and measurement capability information, which may include reporting the measurement capability of one first system, a combination of measurement capabilities of multiple first systems, or a combination of the measurement capabilities of the terminal itself and multiple first systems.

[0093] In some optional embodiments, the sensing measurement capability information includes one or more of the following: The terminal supports the standard information of the first system for sensing and measurement.

For example, the base station provides frequency band information or SSID information to the terminal.

[0118] In some optional embodiments, the detection request information carries one or more of the following: High-layer signaling, physical layer signaling, and application layer data.

[0119] Specifically, the base station triggers the terminal to detect the reference signal of the first system through the detection request information. This can be triggered by higher layer signaling (such as RRC signaling, MAC-CE), physical layer signaling, or application layer data. This application embodiment does not limit this.

[0120] In some optional embodiments, the method further includes: Based on the default detection information, the reference signal sent by the first detection system is detected.

[0122] In some optional embodiments, the detection of the reference signal sent by the first system device, and the acquisition of reference signal information, includes: When the triggering conditions are met, the reference signal sent by the first system device is detected to obtain the reference signal information; The triggering conditions include one or more of the following: The signal quality received by the terminal from the second system network-side device is lower than the first threshold.

[0123] Optionally, in addition to the base station of the second system instructing the terminal to detect the reference signal of the first system, the terminal may also detect the reference signal of the first system on its own. The triggering condition may be: the signal quality of the second system network-side device received by the terminal is lower than a first threshold, and / or the signal quality of the source sensing signal of the second system network-side device received by the terminal is lower than a second threshold.

[0124] Optionally, the first and second thresholds can be preset, predefined, or indicated by the network-side device of the second system, and are not limited here.

[0125] In some optional embodiments, the method further includes: Receive auxiliary information sent by the network-side device of the second system, the auxiliary information being used to indicate the discovery of the first system to be detected.

[0126] Specifically, the network-side equipment of the second system can also send out auxiliary data to help the terminal quickly discover the first system, such as indicating the frequency point, access bandwidth, network service number (PLMN, SSID) of the first system.

[0127] For example, in certain application scenarios (such as supermarkets and airports), the Wi-Fi system is deployed by operator A. In this case, network devices can provide detection assistance information or high-priority detection signal selection information so that the UE can quickly perform detection and select a signal source. For instance, the base station provides frequency band information or SSID information to the terminal.

[0128] In some optional embodiments, the method further includes: Receive sensing and measurement configuration information sent by the network-side equipment of the second system; The reference signal sent by the first sensing and measurement system based on the aforementioned sensing and measurement configuration information.

[0129] Specifically, after the terminal sends reference signal information to the network-side device of the second system, the network-side device of the second system can configure the UE to receive the reference signal sent by the first system and perform measurement tasks when sending sensing measurement configuration information.

[0130] The embodiments of this application can solve the problem of poor quality of sensing signals transmitted by the serving base station, improve sensing accuracy and user satisfaction, and at the same time reduce the wireless resources consumed by the serving base station in transmitting sensing signals.

[0131] Figure 6 This is a second schematic flowchart of the method for obtaining reference signal information provided in the embodiments of this application, as shown below. Figure 6 As shown, the method for acquiring reference signal information is applied to the second system network-side equipment accessed by the terminal, that is, the executing entity of the method for acquiring reference signal information is the second system network-side equipment accessed by the terminal, such as a base station; the steps of the method for acquiring reference signal information include: Step 600: Receive reference signal information sent by the receiving terminal after detecting the reference signal sent by the first system device; The reference signal can be used for sensing measurements in the second system.

[0132] Specifically, in order to avoid inaccurate sensing measurements due to weak sensing reference signals received by the terminal from the outdoor base station it is camped on, the terminal can autonomously search for sensing reference signals sent by other available devices. These other devices are different from the outdoor base station devices it is camped on.

[0133] Specifically, the terminal autonomously searches for available reference signals, i.e., the reference signals of the first system, such as gNBs of other operators deployed near or indoors with the example terminal, or WI-FI devices; the terminal can determine the reference signals that can be used for sensing based on the search results, and generate reference signal information, which is used to characterize one or more parameters of the reference signals of the first system detected by the terminal.

[0134] The reference signals for autonomous search can be: Wi-Fi signals, Long Term Evolution (LTE) signals, NR signals sent by other operator base stations, Bluetooth signals, and visible light signals, without any limitation.

[0135] It should be noted that the reference signal here refers to a known signal or channel data from the perspective of the terminal, including but not limited to: pilot signals, channel quality reference signals, beacon signals, broadcast data, etc.

[0136] Specifically, after the terminal detects the reference signal from the first system and obtains the reference signal information, it can send the reference signal information to the network-side device of the second system so that the second system can perform sensing measurements. These sensing measurements include, but are not limited to: signal energy measurement, signal quality measurement, multipath delay measurement (e.g., for sensing the distance and position of the object being measured), Doppler frequency shift measurement (e.g., for sensing the scalar velocity and vector velocity of the object being measured), and signal angle of arrival measurement.

[0137] like Figure 5 The sensing mode shown is a dual-site mode. The UE is located indoors, performing sensing and measurement tasks, and the object being sensed is also indoors. The gNB (second system network-side equipment) where the UE is hosted is located outdoors, isolated from the UE by a wall. One or more Wi-Fi devices (first system equipment) are deployed indoors. The terminal can then detect the reference signal sent by the Wi-Fi device, obtain the reference signal information, and send it to the gNB where the UE is hosted.

[0138] Optionally, when configuring sensing measurement signals, the network-side equipment of the second system can configure the terminal to receive signals sent by other systems, such as the first system, and perform measurement tasks. This solves the problem of poor quality sensing signals sent by the serving base station, improves sensing accuracy and user satisfaction, and reduces the wireless resources consumed by the serving base station in sending sensing signals.

[0139] The reference signal information acquisition method provided in this application embodiment obtains reference signal information by actively probing the reference signal of the first system by the terminal, and sends the reference signal information of the first system to the network-side device of the second system accessed by the terminal for the second system to perform sensing measurement. This avoids the defect that the reference signal of the network-side device of the second system accessed by the terminal is weak when it arrives at the terminal, resulting in low accuracy of the sensing measurement results. It effectively improves the accuracy of the sensing measurement results and reduces the wireless resources spent by the network-side device of the second system accessed by the terminal to send sensing signals.

[0140] In some optional embodiments, the reference signal information includes one or more of the following: The standard information of the first system; The bandwidth information of the first system; Frequency band information of the first system; The network identification number of the first system; Quality information of the reference signal of the first system; The periodicity information of the reference signal of the first system.

[0141] Specifically, the parameters of the reference signal, i.e., the reference signal information, may include at least one of the following (a1)-(a6): (a1) The standard information of the first system may include one or more standard information of the first system; (a2) The bandwidth information of the first system may include the bandwidth information of one or more first systems; (a3) The frequency band information of the first system may include one or more frequency band information of the first system; or, it may include one or more bandwidth information of the first system and the corresponding frequency band information. (a4) The network identification number of the first system, such as: the PLMN of the communication system, the Service Set Identifier (SSID) of Wi-Fi; (a5) Quality information of the reference signal of the first system, such as: Received Signal Strength Indication (RSSI) or Reference Signal Received Power (RSRP); (a6) The period information of the reference signal of the first system may specifically include the period value of the reference signal measurement.

[0142] Optionally, the quality information of the reference signal can be reported in absolute or relative terms, such as relative to the threshold value indicated by the base station or a preset reference value.

[0143] In one embodiment, the terminal detects the sensing signal sources of the first system and reports the sensing signal resources of candidate first systems to the base station. During the detection process, the terminal implements the detection itself. This can be done through the following two methods: Method 1: The terminal does not store the first system access information (such as the channel location and time information of the synchronization signal). The terminal first searches for synchronization signals, then reads broadcast information, and then obtains one or more available reference signal information (such as signal transmission period, frequency domain density, bandwidth), and measures the reference signals.

[0144] Method 2: The terminal stores the first system access information (such as the channel location of the synchronization signal, time information, and the receiving location of the broadcast signal). The terminal directly detects the broadcast control channel and receives scheduling information. Based on the scheduling information, it receives and reads the broadcast information, thereby obtaining one or more available reference signal information (such as signal transmission period, frequency domain density, bandwidth), and measures the reference signal.

[0145] The following is an example of the reporting command: (b1) Standard information for the first system: NR.

[0146] Optionally, the version number of the standard can also be reported, such as NR rel-17 or NR rel-18.

[0147] (b2) Bandwidth and frequency band information of the first system: such as system bandwidth 400MHz; frequency band band n261; (b3) Network identification number of the first system: such as PLMN ID=46004 (b4) Quality information of the reference signal of the first system: Measured value of the received indication signal of the measurement signal: e.g., RSSI = -73dBm; (b5) Period information of the reference signal of the first system: such as 40ms.

[0148] Optionally, in the embodiments of this application, the bandwidth information of the first system reported by the terminal may refer to the channel bandwidth of the system communication or the signal bandwidth that can be used for sensing measurement, and different reporting methods may be used as needed.

[0149] Optionally, the quality information of the reference signal of the first system can be reported in absolute value (as shown in Table 2 below) or in relative value (such as the reporting threshold information relative to the reference signal information indicated by the base station) (as shown in Table 3 below).

[0150] Table 2: RSSI Measurement Reporting Mapping

[0151] As shown in Table 2, the terminal maps or quantizes the reported values ​​based on the RSSI values ​​of the measured sensing signals and the quantization relationship in Table 2.

[0152] Table 3: RSSI Measurement Reporting Mapping

[0153] Optionally, the value of threshold 1 is a threshold value indicated by the network-side device of the second system. It can also be specified by the protocol or obtained through other signaling configurations.

[0154] Optionally, the increment between adjacent reported values ​​in Table 3 is 1 dB, which is only an example and is not limited to this value. For example, it could be 1.5 dB, 2 dB, or 3 dB. In the future, to reflect flexibility, the increment can be different.

[0155] As shown in Table 3, the terminal maps or quantizes the reported values ​​based on the RSSI values ​​of the measured sensing signals and the quantization relationship in Table 3 above.

[0156] In one embodiment, the terminal performs reference signal detection for the first system and reports the reference signal information of the candidate first system to the network-side device of the second system. This detection process is based on the terminal's implementation.

[0157] The following is an example of a reporting command: (c1) System standard information: Wi-Fi; Optionally, the version number of the standard can also be reported, such as 802.11b or 802.11f.

[0158] (c2) Bandwidth and frequency band information of the first system: such as system bandwidth 160MHz; frequency band 6GHz; (c3) The network identifier of the first system: such as SSID=chinanet; (c4) Quality information of the reference signal of the first system: Measured value of the received indication signal of the measurement signal: e.g., RSSI = -73dBm; (c5) Period information of the reference signal of the first system: such as 200ms.

[0159] Optionally, in the embodiments of this application, the bandwidth information of the first system reported by the terminal may refer to the channel bandwidth of the system communication or the signal bandwidth that can be used for sensing measurement. Different reporting or definitions can be made according to the requirements.

[0160] Optionally, the quality information of the reference signal of the first system can be reported in absolute value (as shown in Table 2 above) or in relative value (as shown in Table 3 above).

[0161] Alternatively, for a Wi-Fi system, the terminal can receive a Wi-Fi signal in the following situations: Type A information: Only beacon signals can be received. Since beacon signals are unencrypted signals broadcast by Wi-Fi, all terminals can receive them, regardless of whether the Wi-Fi access point is legitimate or illegitimate.

[0162] Type B information: Other signals transmitted by the Wi-Fi; For legitimate users of the Wi-Fi (e.g., users who know the Wi-Fi password and can communicate with the Wi-Fi), in addition to reading the beacon signal, data communication-related or other control information can be further read. Compared with Type A information, Type B information can provide more reference signals for candidate first systems.

[0163] Type C information: In the evolved version of Wi-Fi, it can support the transmission of sensing functions and sensing signals. At this time, the terminal can receive the sensing signals sent by Wi-Fi and perform sensing measurements. That is, the terminal can use the sensing measurement signals (i.e. reference signals) of Wi-Fi to perform sensing services and measurements.

[0164] In order to facilitate the execution of the sensing tasks issued by the network-side equipment of the second system, the terminal can report one or more of the above-mentioned Class A information, Class B information or Class C information, so that the second system can make a decision on the network-side equipment to determine the reference signal.

For example, if the period threshold of the reference signal is T=100ms, the terminal will only feed back the reference signal of the first system that is less than this period threshold.

[0213] Optionally, if the base station indication signaling does not contain one or more of the probe request information, the terminal may probe the reference signal of the first system according to the default probe information.

[0219] After the terminal sends reference signal information to the network-side device of the second system, the network-side device of the second system can configure the UE to receive the reference signal sent by the first system and perform measurement tasks when sending sensing measurement configuration information.

[0220] Furthermore, after the UE obtains the sensing measurement parameters, it reports them to the network-side device of the second system or the sensing server.

[0221] The embodiments of this application can solve the problem of poor quality of sensing signals transmitted by the serving base station, improve sensing accuracy and user satisfaction, and at the same time reduce the wireless resources consumed by the serving base station in transmitting sensing signals.

[0222] In one embodiment, the application scenario is as follows: The terminal user performing sensing measurements is indoors, the terminal belongs to operator A, and operator A's serving base station is outdoors. An operator B's NR base station gNB-b is deployed indoors, operating in the 28GHz band with a system bandwidth of 400MHz. The terminal can detect the reference signal transmitted by operator B's NR base station gNB-b and use the reference signal transmitted by gNB-b for sensing measurements, thereby improving the accuracy of sensing measurements, reducing the number of sensing signals transmitted by operator A, and improving air interface resource utilization. Specifically, this may include the following steps: Step 1: The terminal reports its sensing and measurement capabilities to the base station, including its sensing and measurement capabilities to the first system; The perception capability reporting process is used by the gNB of the second system to obtain the UE's perception measurement capabilities. Perception measurement capabilities include the terminal's perception measurement capabilities of the first system. The perception measurement capability information reported by the terminal may include at least one of the following: (Capability Item 1): The type of the first system that the terminal supports for sensing and measurement, such as the standard of the first system: NR; (Capability Item 2): The terminal supports the wireless capabilities of the first system for sensing and measurement, such as the bandwidth and / or frequency band supported for receiving signals: For example, it can include frequency band information: n261 (27.5GHz-28.35GHz), n257 (26.5GHz-29.5GHz); For example, it can include bandwidth information: the channel bandwidth is 100MHz or 400MHz; (Capability Item 3): The terminal supports reference signal information for sensing measurements, i.e., the sensing measurement results of the first system supported, including at least one of the following: The intermediate value of the reference signal: Doppler frequency shift.

[0223] Report Supplementary Information 1: Is a detection measurement gap required? This information is used to indicate whether the base station of the second system needs a measurement gap when performing detection and measurement tasks. If a measurement gap is required, the base station of the second system cannot exchange data or information with the terminal during the detection period.

[0224] Report Supplementary Information 2: Detection and Measurement Duration. This information indicates the time required for the base station of the second system to perform the detection and measurement task. It can be one of several candidate values, such as 80ms, 160ms, or 1024ms. For example, if the terminal has access information from the first system, the time required to perform the detection and measurement task will be shorter; otherwise, the time required will be longer.

[0225] Step 2: The base station sends a probe request message; The second system's network-side equipment can send a probe request to the terminal based on the sensing and measurement capability information reported by the terminal, instructing the terminal to probe other operators' NR base stations. The probe request information includes one or more of the following: (e1) Indicates the standard information of the first system detected by the terminal: NR; (e2) Indicates the bandwidth and / or frequency band information of the first system detected by the terminal: 100MHz, frequency point n261 (27.5GHz-28.35GHz); (e3) Expected reporting time of reference signal information: Instructs the terminal to report reference signal information at the expected time or the latest time.

[0227] Optionally, the reporting threshold information can be an absolute value or a relative value. For example, it can be greater than a threshold value relative to a reference signal of the currently camped cell (e.g., greater than 3dB or 6dB). The reference signal can be an SSB, PRS, or CSI-RS signal.

[0228] Step 3: The reference signal information of the first system is reported; The terminal performs reference signal detection for the first system and reports the reference signal information of the candidate first system to the base station. During the terminal's detection process, based on the terminal's own implementation, it can be achieved through the following two methods: Method 1: The terminal does not store the first system access information (such as the channel location and time information of the synchronization signal). The terminal first searches for synchronization signals, then reads broadcast information, and then obtains one or more available reference signal information (such as signal transmission period, frequency domain density, bandwidth), and measures the reference signals.

[0229] Method 2: The terminal stores the first system access information (such as the channel location of the synchronization signal, time information, and the receiving location of the broadcast signal). The terminal directly detects the broadcast control channel and receives scheduling information. Based on the scheduling information, it receives and reads the broadcast information, thereby obtaining one or more available reference signal information (such as signal transmission period, frequency domain density, bandwidth), and measures the reference signal.

[0230] The following is an example of the reporting command: (b1) Standard information for the first system: NR.

[0233] Optionally, in the embodiments of this application, the bandwidth information of the first system reported by the terminal may refer to the channel bandwidth of the system communication or the signal bandwidth that can be used for sensing measurement, and different reporting methods may be used as needed.

[0234] Optionally, the quality information of the reference signal of the first system can be reported in absolute value (as shown in Table 2 below) or in relative value (such as the reporting threshold information relative to the reference signal information indicated by the base station) (as shown in Table 3 below).

[0236] As shown in Table 2, the terminal maps or quantizes the reported values ​​based on the RSSI values ​​of the measured sensing signals and the quantization relationship in Table 2.

[0238] Optionally, the value of threshold 1 is a threshold value indicated by the network-side device of the second system. It can also be specified by the protocol or obtained through other signaling configurations.

[0239] Optionally, the increment between adjacent reported values ​​in Table 3 is 1 dB, which is only an example and is not limited to this value. For example, it could be 1.5 dB, 2 dB, or 3 dB. In the future, to reflect flexibility, the increment can be different.

[0240] As shown in Table 3, the terminal maps or quantizes the reported values ​​based on the RSSI values ​​of the measured sensing signals and the quantization relationship in Table 3 above.

[0241] After the terminal sends reference signal information to the network-side device of the second system, the network-side device of the second system can configure the UE to receive the reference signal sent by the first system and perform measurement tasks when sending sensing measurement configuration information.

[0242] Furthermore, after the UE obtains the sensing measurement parameters, it reports them to the network-side device of the second system or the sensing server.

[0243] The embodiments of this application can solve the problem of poor quality of sensing signals transmitted by the serving base station, improve sensing accuracy and user satisfaction, and at the same time reduce the wireless resources consumed by the serving base station in transmitting sensing signals.

[0244] In one embodiment, the application scenario is as follows: the terminal user performing sensing measurements is indoors, the terminal belongs to operator A, and operator A's serving base station is outdoors. A Wi-Fi device (or Wi-Fi hotspot) is deployed indoors, operating in the 5.8GHz band with a system bandwidth of 160MHz. Through the technical solution provided in this embodiment, the terminal can detect signals transmitted by Wi-Fi (e.g., beacon signals) and then use the Wi-Fi signal for sensing measurements. This improves the accuracy of sensing measurements, reduces the amount of sensing signals transmitted by operator A, and improves the utilization rate of air interface resources. Specifically, the steps include: Step 1: The terminal reports its sensing and measurement capabilities to the base station, including its sensing and measurement capabilities to the first system; The perception capability reporting process is used by the gNB of the second system to obtain the UE's perception measurement capabilities. Perception measurement capabilities include the terminal's perception measurement capabilities of the first system.

[0245] Optionally, to facilitate subsequent measurements by the first system, the terminal may also report the following: Report Supplementary Information 1: Is a detection measurement gap required? This information is used to indicate whether the base station of the second system needs a measurement gap when performing detection and measurement tasks. If a measurement gap is required, the base station of the second system cannot exchange data or information with the terminal during the detection period.

[0246] Report Supplementary Information 2: Detection and Measurement Duration. This information indicates the time required for the base station of the second system to perform the detection and measurement task. It can be one of several candidate values, such as 80ms, 160ms, or 1024ms. For example, if the terminal has access information from the first system, the time required to perform the detection and measurement task will be shorter; otherwise, the time required will be longer.

[0247] Step 2: The base station sends a probe request message; The network-side equipment of the second system can send a detection request to the terminal based on the sensing and measurement capability information reported by the terminal, instructing the terminal to detect the Wi-Fi signal. The detection request information includes one or more of the following: (f1) Indicates the standard information of the first system detected by the terminal: Wi-Fi; (f2) Indicates the bandwidth and / or frequency band information of the first system detected by the terminal: 160MHz, frequency point 6GHz; (f3) Expected reporting time of reference signal information: Instructs the terminal to report the expected time of reference signal information, or the latest time.

(f4) Reference signal information reporting threshold: The indicator threshold RSSI = -75dBm, and the terminal only feeds back the reference signal of the first system that is greater than this threshold.

[0248] (f5) Period threshold of the reference signal used for sensing measurement: indicates the maximum period threshold T=200ms, and the terminal only feeds back the reference signal of the first system that is less than this period threshold.

[0249] Optionally, the reporting threshold information can be an absolute value or a relative value. For example, it can be greater than a threshold value relative to a reference signal of the currently camped cell (e.g., greater than 3dB or 6dB). The reference signal can be an SSB, PRS, or CSI-RS signal, configured or indicated by the base station, or specified by the protocol.

[0250] Optionally, in certain application scenarios (such as supermarkets and airports), the Wi-Fi system is deployed by operator A. In this case, the network equipment can provide detection assistance information or high-priority detection signal selection information to enable the UE to quickly perform detection and select a signal source. For example, the base station provides frequency band information or SSID information to the terminal.

[0251] Step 3: The reference signal information of the first system is reported; The terminal performs reference signal detection for the first system and reports the reference signal information of the candidate first system to the network-side device of the second system. This detection process is implemented based on the terminal's own capabilities.

[0252] The following is an example of a reporting command: (c1) System standard information: Wi-Fi; Optionally, the version number of the standard can also be reported, such as 802.11b or 802.11f.

[0256] Alternatively, for a Wi-Fi system, the terminal can receive a Wi-Fi signal in the following situations: Type A information: Only beacon signals can be received. Since beacon signals are unencrypted signals broadcast by Wi-Fi, all terminals can receive them, regardless of whether the Wi-Fi access point is legitimate or illegitimate.

[0257] Type B information: Other signals transmitted by the Wi-Fi; For legitimate users of the Wi-Fi (e.g., users who know the Wi-Fi password and can communicate with the Wi-Fi), in addition to reading the beacon signal, data communication-related or other control information can be further read. Compared with Type A information, Type B information can provide more reference signals for candidate first systems.

[0258] Type C information: In the evolved version of Wi-Fi, it can support the transmission of sensing functions and sensing signals. At this time, the terminal can receive the sensing signals sent by Wi-Fi and perform sensing measurements. That is, the terminal can use the sensing measurement signals (i.e. reference signals) of Wi-Fi to perform sensing services and measurements.

[0259] In order to facilitate the execution of the sensing tasks issued by the network-side equipment of the second system, the terminal can report one or more of the above-mentioned Class A information, Class B information or Class C information, so that the second system can make a decision on the network-side equipment to determine the reference signal.

[0260] After the terminal sends reference signal information to the network-side device of the second system, the network-side device of the second system can configure the UE to receive the reference signal sent by the first system and perform measurement tasks when sending sensing measurement configuration information.

[0261] Furthermore, after the UE obtains the sensing measurement parameters, it reports them to the network-side device of the second system or the sensing server.

[0262] The embodiments of this application can solve the problem of poor quality of sensing signals transmitted by the serving base station, improve sensing accuracy and user satisfaction, and at the same time reduce the wireless resources consumed by the serving base station in transmitting sensing signals.
