[0140] 1. Communication and perception integration / synaesthesia integration:

[0141] Future Beyond 5G (B5G) and 6G wireless communication systems are expected to provide a variety of high-precision sensing services, such as indoor positioning for robot navigation, Wi-Fi sensing for smart homes, and radar sensing for autonomous vehicles. Sensing and communication systems are typically designed separately and occupy different frequency bands. Integrated Sensing and Communication (ISAC) enables sensing and communication systems to share the same frequency band and hardware, improving frequency efficiency and reducing hardware costs. ISAC will become a key technology for future wireless communication systems, supporting many important application scenarios. Typical applications of ISAC include navigation and obstacle avoidance for autonomous vehicles, indoor positioning and activity recognition based on Wi-Fi, communication and sensing for unmanned aerial vehicles, extended reality (XR), and radar and communication integration. Each application has different requirements, limitations, and regulatory issues. ISAC has attracted significant research interest and attention from both academia and industry.

[0142] ISAC achieves low-cost, integrated communication and perception capabilities through shared hardware and software-defined functions. Its key features include: a unified and simplified architecture; reconfigurable and scalable functions; and improved efficiency and reduced costs. The advantages of integrated communication and perception are threefold: reduced equipment cost and size; improved spectrum utilization; and enhanced system performance.

[0143] Currently, typical communication perception integration scenarios that are expected to be achieved through technical upgrades based on the 5G communication system architecture are shown in the following table.

[0144] Table 1 Typical scenarios of communication perception integration

[0145] There are six basic sensing modes, depending on the difference between the sending and receiving nodes of the sensing signal, as shown in Figure 2:

[0146] (1) Base station self-transmitting and self-receiving sensing: In this sensing mode, base station A sends a sensing signal and performs sensing measurement by receiving the echo of the sensing signal.

[0147] (2) Inter-base station air interface sensing: Base station B receives the sensing signal sent by base station A and performs sensing measurements.

[0148] (3) Uplink air interface perception: Base station A receives the perception signal sent by terminal A and performs perception measurement.

[0149] (4) Downlink air interface perception: Terminal B receives the perception signal sent by base station B and performs perception measurement.

[0152] It's worth noting that each sensing method in Figure 2 uses one sensing signal transmitting node and one sensing signal receiving node as examples. In actual systems, one or more sensing methods can be selected based on different sensing use cases and requirements, and each sensing method can have one or more transmitting and receiving nodes. The sensing targets in Figure 2 use people and vehicles as examples, assuming neither person nor vehicle carries or has installed signal transceiver / receiver equipment. In actual scenarios, the range of sensing targets will be much richer.

[0202] The communication operation execution method, apparatus, and related equipment provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0203] 3 , which is a flow chart of a method for executing a communication operation according to an embodiment of the present application. As shown in FIG3 , the method for executing a communication operation includes the following steps:

[0204] Step 101: The first device performs a first operation;

[0205] The first operation includes at least one of the following:

[0206] Acquire a first timing offset and a second timing offset, and determine a third timing offset based on the first timing offset and the second timing offset;

[0207] Acquire a first frequency deviation and a second frequency deviation, and determine a third frequency deviation based on the first frequency deviation and the second frequency deviation;

[0208] receiving a third timing deviation or a third frequency deviation sent by the second device or the third device;

[0209] Perform configuration operations;

[0210] The first timing offset is a sampling timing offset between a receiver of the first signal and a transmitter of the first signal, the second timing offset is a sampling timing offset between a receiver of the second signal and a transmitter of the second signal, and the third timing offset is a sampling timing offset between a receiver of the second signal and a receiver of the first signal;

[0211] The first frequency deviation is a local oscillator frequency deviation between a receiver of the first signal and a transmitter of the first signal; the second frequency deviation is a local oscillator frequency deviation between a receiver of the second signal and a transmitter of the second signal; and the third frequency deviation is a local oscillator frequency deviation between a receiver of the second signal and a receiver of the first signal.

[0212] The configuration operation is used to assist in a process of acquiring the third timing offset or the third frequency offset;

[0213] The sender of the first signal and the sender of the second signal are the same device.

[0214] The first signal and the second signal may be understood as calibration signals, and the first signal and the second signal may be the same or different.

[0215] In one embodiment, the recipient of the first signal is the second device, or the recipient of the first signal is the first device. The sender of the first signal and the sender of the second signal may be a fourth device. It should be noted that when the first device serves as the recipient of the first signal, the first device measures the first signal sent by the fourth device to obtain a first measurement quantity. When the first device performs the function of the second device, the first device may serve as the recipient of the first signal.

[0216] In one embodiment, the recipient of the second signal is a third device, or the recipient of the second signal is a first device. The sender of the first signal and the sender of the second signal may be a fourth device. It should be noted that when the first device serves as the recipient of the second signal, the first device measures the second signal sent by the fourth device to obtain a second measurement value. When the first device performs the functions of the third device, the first device may serve as the recipient of the second signal.

[0217] In one embodiment, the recipient of the first signal is a second device, the recipient of the second signal is a third device, and the sender of the first signal and the sender of the second signal may be a fourth device or the first device. When the first device performs the function of the fourth device, the first device may serve as the sender of the first signal and the sender of the second signal.

[0218] It should be noted that the process of assisting in acquiring the third timing offset or the third frequency offset may also be described as cooperating with or configuring the process of acquiring the third timing offset or the third frequency offset.

[0219] In one embodiment, through the configuration operation, the receiving device of the first signal and the receiving device of the second signal, as well as the sending device of the first signal and the second signal can be determined, and the sending, receiving, processing or reporting behavior of the first signal and the second signal can be configured.

[0220] It should be noted that the fourth device can be understood as a reference station. By using the reference station used for calibration, the sampling timing deviation and local oscillator frequency offset between a device pair (such as a device pair consisting of a second device and a third device) can be obtained; this is particularly applicable to situations where there is no LOS path between the device pairs. Obtaining the sampling timing deviation and local oscillator frequency offset between the device pairs can be used to calibrate the sampling timing deviation and local oscillator frequency offset between the device pairs; therefore, the method described in this embodiment can be understood as a method for calibrating the sampling timing deviation and local oscillator frequency offset between device pairs. The device pair refers to a pair of devices or two devices. The calibration method of this embodiment is based on the calibration between two devices and can be applied to the calibration between multiple devices.

[0221] Typical application scenarios include:

[0222] (1) In the synaesthesia integration scenario, the sampling timing deviation and local oscillator frequency offset between the transmitter and receiver of the perception signal are calibrated.

[0223] (2) Time and frequency synchronization between TRPs in communication scenarios (e.g., cell-free).

[0224] Compared with the calibration method based on intelligent metasurface (Reconfigurable Intelligent Surface, RIS), backscatter communication (Back Scatter Communication, BSC) equipment in the related art, the reference station proposed in the embodiment of the present application can be a base station, an ordinary UE or a customized UE specifically used for calibration, which has the advantages of larger coverage and easier implementation.

[0225] The calibration scheme proposed in this embodiment of the application allows a single reference station to calibrate multiple links within its coverage area. Therefore, calibration signals can be configured on a per-cell basis. Compared to calibration methods based on RIS and BSC in related technologies, this approach is simpler and can conserve resources (e.g., time-frequency resources and power).

[0226] As a specific implementation, as shown in FIG4 , the communication operation execution method may include the following process:

[0227] (1) Sending and receiving calibration signals

[0228] (1a): The fourth device sends a first signal, and the second device receives the first signal.

[0229] According to the signal configuration of the first signal (see the explanation of the sensing signal configuration above), the sending time of the first signal is t1 and the carrier frequency is f1. Since there are certain errors in the sampling clock and local oscillator frequency of each device, the fourth device sends the first signal at t1 of its own local clock. The actual time is The fourth device generates a first signal with a carrier frequency of f1 according to its own frequency source, and its actual carrier frequency is Similarly, the actual time at time t1 of the local clock of the second device is The actual frequency of the local oscillator signal with a frequency of f1 generated by the second device according to its own frequency source is

[0230] As shown in Figure 5, and The time deviation between them is Δt1, that is, the sampling timing deviation of the second device relative to the fourth device, which is recorded as the first timing deviation. Then when the fourth device sends the first signal, the time of the local clock of the second device is

[0231] Assume that the signal propagation delay of the first signal from the fourth device to the second device is τ1. Then when the second device receives the first signal, the time of the local clock of the second device is Since the configured signal sending time is t1, the second device uses its local clock time As the sending time of the first signal, the signal propagation delay extracted by the second device and the first timing offset are added together to form: τ1-Δt1.

[0232] In addition, and The frequency deviation between them is Δf1, that is, the local oscillator frequency deviation of the second device relative to the fourth device, which is recorded as the first frequency deviation. Then the local oscillator signal frequency of the second device is

[0233] Assume that the Doppler frequency caused by the relative motion between the second device and the fourth device is f d1 , before the second device receives the first signal, the carrier frequency of the first signal is modulated by the Doppler frequency and becomes Since the local oscillator signal frequency of the second device is Therefore, the result of superimposing the Doppler frequency extracted by the second device on the first frequency deviation is: d1 -Δf1.

[0234] (1b): The fourth device sends the second signal, and the third device receives the second signal.

[0235] This is similar to the sending of the first signal, as shown in FIG6 .

[0236] According to the signal configuration of the second signal (see the explanation of the sensing signal configuration above), the second signal is sent at time t2 and carrier frequency f2. Since there are certain errors in the sampling clock and local oscillator frequency of each device, the fourth device sends the second signal at time t2 of its own local clock. The actual time is The fourth device generates a second signal with a carrier frequency of f2 according to its own frequency source, and its actual carrier frequency is Similarly, the actual time at time t2 of the local clock of the third device is The actual frequency of the local oscillator signal with a frequency of f2 generated by the third device according to its own frequency source is

[0237] set up and The time deviation between them is Δt2, that is, the sampling timing deviation of the third device relative to the fourth device, which is recorded as the second timing deviation. Then when the fourth device sends the second signal, the time of the local clock of the third device is

[0238] Assume that the signal propagation delay of the second signal from the fourth device to the third device is τ2. Then when the third device receives the second signal, the time of the local clock of the third device is Since the configured signal sending time is t2, the third device uses the time of its local clock As the sending time of the second signal, the signal propagation delay extracted by the third device is added to the second timing offset to obtain the result: τ2-Δt2.

[0239] In addition, and The frequency deviation between them is Δf2, that is, the local oscillator frequency deviation of the third device relative to the fourth device, which is recorded here as the second frequency deviation. Then the local oscillator signal frequency of the third device is

[0240] Assume that the Doppler frequency caused by the relative motion between the third device and the fourth device is f d2 , before the third device receives the second signal, the carrier frequency of the second signal is modulated by the Doppler frequency and becomes Since the local oscillator signal frequency of the third device is Therefore, the result of adding the Doppler frequency extracted by the second device to the local oscillator frequency deviation is: d2 -Δf2.

[0241] (2): Extraction of sampling timing deviation and local oscillator frequency deviation of the second device and the third device relative to the fourth device.

[0242] In this embodiment, the positions and movement speeds of the fourth device, the second device, and the third device are known, so the above τ1, τ2, and f d1 and f d2 The positional relationship and relative speed between the three devices can be obtained and are therefore known. Therefore:

[0243] τ1-Δt1 and f obtained by the second device measurement d1 -Δf1, combined with the known τ1 and f d1 , it is possible to determine a first timing deviation Δt1 of the second device relative to the fourth device and a first frequency deviation Δf1 of the second device relative to the fourth device.

[0244] τ2-Δt2 and f obtained by measuring with a third device d2 -Δf2, combined with the known τ2 and f d2 , it is possible to determine a second timing deviation Δt2 of the third device relative to the fourth device and a second frequency deviation Δf2 of the third device relative to the fourth device.

[0245] (3): Extraction of sampling timing deviation and local oscillator frequency deviation of the third device relative to the second device.

[0246] Combining the first timing deviation Δt1 of the second device relative to the fourth device and the second timing deviation Δt2 of the third device relative to the fourth device, the sampling timing deviation of the third device relative to the second device can be determined, which is Δt2-Δt1, here referred to as the third timing deviation.

[0247] Similarly, by combining the first frequency deviation Δf1 of the second device relative to the fourth device and the second frequency deviation Δf2 of the third device relative to the fourth device, the local oscillator frequency deviation of the third device relative to the second device can be determined, which is Δf2-Δf1, here referred to as the third frequency deviation.

[0248] It should be noted that after the third timing offset and the third frequency offset are determined, the third timing offset and the third frequency offset may be used to compensate and correct the signals sent and received between the second device and the third device.

[0249] For example, in a synaesthesia integration scenario: after the second device and the third device perform perception and obtain the perception results, the perception measurement quantity or the perception result is compensated with Δt2-Δt1 and Δf2-Δf1 respectively, so as to obtain the correct time delay and Doppler of the path reflected by the perceived target.

[0250] For example, in a communication scenario (e.g., cell free), the sampling timing and local oscillator frequency between TRPs can be synchronized using Δt2-Δt1 and Δf2-Δf1 respectively to perform coherent transmission between TRPs.

[0251] It can be understood that the positive and negative signs of Δt1, Δt2, Δf1 and Δf2 in the above analysis depend on the definition of relative delay and relative frequency deviation in the specific implementation process. According to the above analysis and the definition of relative delay and relative frequency deviation in specific application, the third timing deviation can also be Δt2+Δt1, -Δt2+Δt1 or -Δt2-Δt1, and the third frequency deviation can also be Δf2+Δf1, -Δf2+Δf1 or -Δf2-Δf1. This embodiment does not limit this.

[0252] It should be noted that the fourth device can be understood as a reference station, which can include a network-side device (such as a base station) or a terminal; the second device can be one of the devices in the device pair that needs to be calibrated, for example, it can be a network-side device or a terminal; the third device can be the other device in the device pair that needs to be calibrated, which can be a network-side device or a terminal; the first device can perform the function of the fourth device, or the second device or the third device, or the first device can be a device other than the fourth device, the second device and the third device, or the first device can be a core network device (such as a perception function network element), or the CU in the 5G centralized unit (CU)-distributed unit (DU) architecture, etc.

[0253] In the A-transmit, B-receive sensing mode, the transmitting and receiving devices use their own frequency sources to generate local oscillator signals for sensing signal generation, frequency conversion, and sampling. Due to device non-idealities, the local oscillator signals generated by the frequency sources of each device may have frequency differences, especially for terminal devices with relatively low hardware costs.

[0254] The difference in local oscillator frequency between the transmitter and receiver of the sensing signal causes the receiving device to add sampling timing deviation and local oscillator frequency deviation to the signal received by the sensing signal. Sampling timing deviation and local oscillator frequency deviation can introduce significant additional errors in the estimation of target parameters (range, speed).

[0255] The embodiments of the present application can solve the problem that sampling timing deviation and local oscillator frequency deviation will cause large, additional errors in the estimation of parameters (distance, speed) of the perceived target by deploying a reference station for perception calibration.

[0256] The embodiment of the present application proposes a reference station-assisted time-frequency calibration method, in which the fourth device (i.e., the reference station) sends a calibration signal, and the second device and the third device receive the calibration signal, thereby extracting the sampling timing deviation and local oscillator frequency deviation between the second device and the third device and the fourth device respectively; wherein the calibration signal may include at least one of the first signal and the second signal. Further, the sampling timing deviation and local oscillator frequency deviation between the second device and the third device can be obtained. The second device and the third device can be the transmitter and receiver of the perception signal in the synaesthesia integration scenario, or the transceiver of the communication signal in the communication scenario. Therefore, the embodiment of the present application can be used to compensate or correct the perception measurement quantity or perception result in the synaesthesia integration scenario, or for time-frequency synchronization between TRPs during coherent transmission of multiple TRPs in the communication scenario. The fourth device in the embodiment of the present application only needs to send a signal, so the perception and communication capabilities of the fourth device are relatively low, and it has the advantages of being easy to implement and saving resource overhead, and is particularly suitable for situations where there is no LOS path between the second device and the third device.

[0257] In an embodiment of the present application, a first device obtains a first timing offset and a second timing offset, and determines a third timing offset based on the first timing offset and the second timing offset; or obtains a first frequency offset and a second frequency offset, and determines a third frequency offset based on the first frequency offset and the second frequency offset; or receives a third timing offset or a third frequency offset sent by a second device or a third device; or performs a configuration operation; wherein the first timing offset is a sampling timing offset between a receiver of the first signal and a sender of the first signal, the second timing offset is a sampling timing offset between a receiver of the second signal and a sender of the second signal, and the third timing offset is a sampling timing offset between a receiver of the second signal and a sender of the first signal; the first frequency offset is a local oscillator frequency offset between a receiver of the first signal and a sender of the first signal, the second frequency offset is a local oscillator frequency offset between a receiver of the second signal and a sender of the second signal, and the third frequency offset is a local oscillator frequency offset between a receiver of the second signal and a receiver of the first signal; the configuration operation is used to assist in the process of obtaining the third timing offset or the third frequency offset; and the sender of the first signal and the sender of the second signal are the same device. This enables the device to use at least one of the third timing deviation and the third frequency deviation, supports calibration of the third timing deviation or the third frequency deviation, and is beneficial to improving the performance of perception or communication between the receiver of the first signal and the receiver of the second signal.

In other words, the first measurement quantity for measurement reporting included in the first measurement configuration is used to indicate a type of measurement quantity that a receiver of the first signal needs to measure and report, and the second measurement quantity for measurement reporting included in the second measurement configuration is used to indicate a type of measurement quantity that a receiver of the second signal needs to measure and report.

[0264] In this embodiment, the first device sends a first measurement configuration to the second device, or the first device sends a second measurement configuration to the third device, which can configure the behavior of the second device receiving or processing the first signal or the behavior of the third device receiving or processing the second signal, thereby assisting in the process of acquiring the third timing deviation or the third frequency deviation.

[0442] Step (11) The candidate reference station (such as the fourth device) registers with the network and reports its capability information.

[0443] Candidate reference stations report their sensing capabilities to the network, primarily related to their ability to transmit the first and second signals. The transmission and reception of the first and second signals is essentially a process of integrated perception. Therefore, the first and second signals can be understood as sensing signals. Therefore, the capabilities associated with the first and second signals are considered sensing capabilities.

[0444] Step (12) The first device selects a device.

[0445] The first device performs selection of at least one of the fourth device, the second device, and the third device, including at least one of the following:

[0446] The first device determines the fourth device according to: the first information of the candidate reference station and the sensing requirement information (see the above explanation of the sensing requirement information);

[0447] The first device determines the second device according to the first information of the candidate sensing node and the sensing requirement information;

[0448] The first device determines the third device according to the first information of the candidate sensing node and the sensing requirement information.

[0449] Among them, the first information can be found in the description of the first information mentioned above and will not be repeated here.

[0450] The first device obtains at least part of the first information in a manner that includes at least one of the following:

[0451] The first device sends a first query signaling to a candidate reference station or candidate sensing node, instructing it to report at least part of the first information, and the candidate reference station or candidate sensing node then replies with corresponding information to the first device. For example, the candidate reference station or candidate sensing node is a UE, which, after receiving the first query signaling, obtains location information through GPS and then reports it to the first device; or

[0452] The first device sends a second query signaling request to a network node that stores at least part of the first information to obtain information about a candidate reference station or candidate sensing node. For example, if the candidate reference station or candidate sensing node is an RSU, and a network node stores the location information of all roadside units (RSUs) within a certain area, the first device may request the location information of the candidate reference station or candidate sensing node from the network node based on the ID of the candidate reference station or candidate sensing node. For example, if the candidate reference station or candidate sensing node is a base station, the sensing function network element may request information such as the location, power, and receiver sensitivity from the network management function.

[0453] The candidate reference station is at least one reference station within a certain area, from which at least one reference station can be determined as the fourth device for executing this embodiment.

[0454] The candidate sensing nodes are at least two sensing nodes within a certain area, from which at least one second device and at least one third device can be determined.

[0455] It should be noted that, when the first device performs the above device selection, there is a LOS path between the selected fourth device and the second device, and there is a LOS path between the fourth device and the third device.

[0456] Step (13) The first device performs signal configuration of the first signal and the second signal.

[0457] After determining the fourth device (which can be understood as a reference station), the first device sends a first signaling to the fourth device, sends a second signaling to the second device, and sends a third signaling to the third device to instruct the execution of the perception calibration described in this embodiment.

[0458] Among them, the first signaling, the second signaling, or the third signaling can be found in the description of the first signaling, the second signaling, or the third signaling mentioned above, and will not be repeated here.

[0459] Step (14) The first device configures measurement of the second device and the third device.

[0460] In the calibration method described in this embodiment, the second device receives a first signal sent by the fourth device, and the third device receives a second signal sent by the fourth device to perform calibration. Therefore, the first signal is measured by the second device, and the second signal is measured by the third device. To measure the first and second signals, the first device must configure the second and third devices for measurement.

[0461] In one implementation, the first device sends the first measurement configuration to the second device, and sends the second measurement configuration to the third device.

[0462] In one implementation, the second measurement configuration indicates a measurement quantity that needs to be measured and reported, which is obtained by measuring the first signal and is recorded as the first measurement quantity, and includes at least one of the following:

[0463] IQ road data;

[0464] Channel matrix: This can be the channel estimation result of methods such as least squares (LS) and minimum mean squared error (MMSE), or the result after further noise suppression (for example, discrete Fourier transform (DFT) noise suppression);

[0465] Delay spectrum, Doppler spectrum, or delay-Doppler spectrum;

[0466] First delay information: refers to the delay of the LOS path or the first path from the fourth device to the second device, extracted by the second device. It is usually the result of the signal propagation delay superimposed on the first timing offset; that is, the aforementioned τ1-Δt1;

[0467] First Doppler information: refers to the Doppler of the LOS path or the first path from the fourth device to the second device extracted by the second device, which is usually the result of the Doppler frequency caused by the relative motion between the fourth device and the second device superimposed on the first frequency deviation; that is, the aforementioned f d1 -Δf1;

[0468] First timing deviation: the sampling timing deviation of the second device relative to the fourth device extracted by the second device, i.e., the aforementioned Δt1;

[0469] First frequency deviation: the local oscillator frequency deviation of the second device relative to the fourth device extracted by the second device, that is, the aforementioned Δf1.

[0470] In one embodiment, the time configuration for indicating measurement reporting includes at least one of the following:

[0471] Periodic reporting: reporting the first measurement quantity according to a specified time offset and / or period;

[0472] Semi-persistent reporting: reporting the first measurement value according to the specified period after receiving the activation command;

[0473] Aperiodic reporting: reporting the first measurement value at a specified time or when a preset condition is met.

[0474] In one implementation, the second measurement configuration indicates a measurement quantity that needs to be measured and reported, and is obtained by measuring the second signal, recorded as the second measurement quantity, including at least one of the following:

[0475] IQ road data;

[0476] Channel matrix: This can be the channel estimation result of methods such as LS and MMSE, or the result after further noise suppression (for example, DFT noise suppression);

[0477] Delay spectrum, Doppler spectrum, or delay-Doppler spectrum;

[0478] Second delay information: refers to the delay of the LOS path or the first path from the fourth device to the third device, extracted by the third device. It is usually the result of the signal propagation delay superimposed on the second timing offset; that is, the aforementioned τ2-Δt2;

[0479] Second Doppler information: refers to the Doppler of the LOS path or the first path from the fourth device to the third device extracted by the third device, which is usually the result of the Doppler frequency caused by the relative motion between the fourth device and the third device superimposed on the second frequency deviation; that is, the aforementioned f d2-Δf2;

[0480] Second timing deviation: the sampling timing deviation of the third device relative to the fourth device extracted by the third device, i.e., the aforementioned Δt2;

[0481] Second frequency deviation: the local oscillator frequency deviation of the third device relative to the fourth device extracted by the third device, that is, the aforementioned Δf2.

[0482] In one embodiment, the time configuration for indicating measurement reporting includes at least one of the following:

[0483] Periodic reporting: reporting the second measurement quantity according to a specified time offset and / or period;

[0484] Semi-persistent reporting: after receiving the activation command, the second measurement quantity is reported according to the specified period;

[0485] Aperiodic reporting: reporting the second measurement value once at a specified time or when a preset condition is met.

[0486] It should be noted that the types of the first measurement quantity and the second measurement quantity may be the same or different.

[0487] In general, the measurement variable types in the first measurement and the second measurement variable are the same.

[0488] (a) In some implementations, if the second device has strong computing power and is capable of completing all operations of the method described in this embodiment, the second device may report the measured value of the delay information, Doppler information, first timing deviation, or first local oscillator frequency offset of the first measurement quantity.

[0489] Similarly, if the third device has strong computing power and can complete all operations of the method described in this embodiment, the third device can report the measured value of the delay information, Doppler information, second timing deviation, or second local oscillator frequency offset of the second measurement quantity.

[0490] (b) In some embodiments, if the computing power of the second device is insufficient to obtain the delay information, Doppler information, first timing offset, or first local oscillator frequency offset in the first measurement quantity, the second device may report the IQ channel data, channel matrix, delay spectrum, Doppler spectrum, or delay-Doppler spectrum in the first measurement quantity. The device receiving the first measurement quantity (the first device or the third device) then performs the computation to obtain the corresponding measurement value of the delay information, Doppler information, first timing offset, or first local oscillator frequency offset.

[0491] Similarly, if the computing power of the third device is insufficient and it is unable to calculate the delay information, Doppler information, second timing offset, or second local oscillator frequency offset in the second measurement quantity, the third device can report the IQ channel data, channel matrix, delay spectrum, Doppler spectrum, or delay-Doppler spectrum in the second measurement quantity. The device receiving the second measurement quantity (the first device or the second device) then performs the calculation to obtain the corresponding measurement value of the delay information, Doppler information, second timing offset, or second local oscillator frequency offset.

[0492] Step (15) The second device and / or the third device obtains the location information and / or speed information of the fourth device.

[0493] In one embodiment,

[0494] In a case where the first measurement amount includes the first timing offset, the second device may obtain location information of the fourth device;

[0495] In a case where the first measurement quantity includes the first frequency deviation, the second device may obtain speed information of the fourth device;

[0496] In a case where the second measurement amount includes the second timing offset, the third device may obtain the location information of the fourth device;

[0497] When the second measurement quantity includes the second frequency deviation, the third device may obtain speed information of the fourth device.

[0498] In the absence of the above situation, the second device and / or the third device does not need to obtain the location information and / or speed information of the fourth device.

[0499] Obviously, when the second device and / or the third device obtains the location information of the fourth device, the second device and / or the third device can also obtain its own location information; when the second device and / or the third device obtains the speed information of the fourth device, the second device and / or the third device can also obtain its own speed information.

[0500] Optionally, the second device and / or the third device may obtain the location information and / or speed information of the fourth device by: receiving corresponding information content sent by the first device. It should be noted that in step (12), the first device has already obtained the location information and speed information of the fourth device.

[0501] Step (16) The second device and the third device perform measurement reporting.

[0502] Measurement reporting for calibration between the second and third devices, including the following options:

[0503] In one embodiment, the first device calculates and obtains the third sampling clock and / or the third frequency deviation, the second device reports the first measurement quantity to the first device, and the third device reports the second measurement quantity to the first device. After the first device calculates and obtains the third sampling clock and / or the third frequency deviation, at least one of the following is further included:

[0504] (1) The first device sends a third timing offset and / or a third frequency offset to the second device.

[0505] In the synaesthesia scenario, if the perception service is subsequently performed and the second device receives the perception signal and calculates the perception measurement quantity or perception result, this item is present.

[0506] In a communication scenario, if the second device performs time-frequency adjustment to maintain time-frequency synchronization with the third device, this item is present.

[0507] (2) The first device sends a third timing offset and / or a third frequency offset to the third device.

[0508] In the synaesthesia scenario, if a perception service is subsequently performed and a third device receives a perception signal and calculates a perception measurement quantity or a perception result, this item is present.

[0509] In a communication scenario, if the third device performs time-frequency adjustment to maintain time-frequency synchronization with the second device, this item is present.

[0510] (3) The first device does not need to send the third timing offset and / or the third frequency offset.

[0511] In the synaesthesia scenario, if a perception service is subsequently performed and the first device calculates a perception measurement quantity or a perception result, this item is present.

[0512] In one embodiment, the second device calculates the third timing offset and / or the third frequency offset, and the second device obtains the second measurement value sent by the third device. After the second device calculates the third timing offset and / or the third frequency offset, one of the following situations is also included:

[0513] (1) The second device sends a third timing offset and / or a third frequency offset to the third device.

[0514] In the synaesthesia scenario, if a perception service is subsequently performed and a third device receives a perception signal and calculates a perception measurement quantity or a perception result, this item is present.

[0515] In a communication scenario, if the third device performs time-frequency adjustment to maintain time-frequency synchronization with the second device, this item is present.

[0516] (2) The second device sends the third timing offset and / or the third frequency offset to the first device.

[0517] In the synaesthesia scenario, if a perception service is subsequently performed and the first device calculates a perception measurement quantity or a perception result, this item is present.

[0518] (3) The second device does not need to send the third timing offset and / or the third frequency offset.

[0519] In the synaesthesia scenario, the perception service is subsequently performed, and the second device receives the perception signal and calculates to obtain the perception measurement value or perception result. Therefore, the second device does not need to send the third timing offset and / or the third frequency offset.

[0520] In a communication scenario, the second device performs time-frequency adjustment to maintain time-frequency synchronization with the third device.

[0521] In one embodiment, the third device calculates the third timing offset and / or the third frequency offset, and obtains the first measurement value sent by the second device. After the third device calculates the third timing offset and / or the third frequency offset, one of the following situations is also included:

[0522] (1) The third device sends a third timing offset and / or a third frequency offset to the second device.

[0523] In the synaesthesia scenario, if the perception service is subsequently performed and the second device receives the perception signal and calculates the perception measurement quantity or perception result, this item is present.

[0524] In a communication scenario, if the second device performs time-frequency adjustment to maintain time-frequency synchronization with the third device, this item is present.

[0525] (2) The third device sends a third timing offset and / or a third frequency offset to the first device.

[0526] In the synaesthesia scenario, if a perception service is subsequently performed and the first device calculates a perception measurement quantity or a perception result, this item is present.

[0527] (3) The third device does not need to send the third timing offset and / or the third frequency offset.

[0528] In the synaesthesia scenario, the subsequent execution of the perception service is also performed by the third device receiving the perception signal and solving it to obtain the perception measurement quantity or perception result. Therefore, the third device does not need to send the third timing offset and / or the third frequency offset.

[0529] In a communication scenario, the third device performs time-frequency adjustment to maintain time-frequency synchronization with the second device.

[0530] In one implementation, the first data reported by the second device includes:

[0531] an ID of a link in which the fourth device sends the first signal and the second device receives the first signal, or an ID of the fourth device and the second device;

[0532] ID of the first signal;

[0533] location information of the second device;

[0534] speed information of the second device;

[0535] Timestamp: used to indicate the time when the first signal is received;

[0536] a first measurement quantity;

[0537] Information related to timing adjustment and / or local oscillator frequency adjustment performed by the second device during reception of the first signal.

[0538] In one implementation, the second data reported by the third device includes:

[0539] a link ID for sending the second signal by the fourth device and receiving the second signal by the third device, or IDs of the fourth device and the third device;

[0540] The ID of the second signal;

[0541] location information of a third device;

[0542] speed information of the third device;

[0543] Timestamp: used to indicate the time when the second signal is received;

[0544] a second measurement quantity;

[0545] Information related to timing adjustment and / or local oscillator frequency adjustment of the third device during the second signal reception.

[0546] Step (17) Use of calibration information.

[0547] In one embodiment, in a synaesthesia scenario, when performing a subsequent perception task:

[0548] If the second device sends the perception signal and the third device receives the perception signal, the third timing deviation Δt2-Δt1 can be compensated to the delay information, and the third frequency deviation Δf2-Δf1 can be compensated to the Doppler information: that is, the third timing deviation Δt2-Δt1 is added or subtracted from the measured delay value to obtain the accurate value of the signal propagation delay, and the third frequency deviation Δf2-Δf1 is added or subtracted from the measured Doppler value to obtain the accurate value of the Doppler frequency.

[0549] If the third device sends the perception signal and the second device receives the perception signal, the third timing deviation Δt1-Δt2 can be compensated to the delay information, and the third frequency deviation Δf1-Δf2 can be compensated to the Doppler information: that is, the third timing deviation Δt1-Δt2 is added or subtracted from the measured delay value to obtain the accurate value of the signal propagation delay, and the third frequency deviation Δf1-Δf2 is added or subtracted from the measured Doppler value to obtain the accurate value of the Doppler frequency.

[0550] In one embodiment, in a communication scenario, in order to synchronize TRPs to achieve coherent transmission of multiple TRPs, the following options are available:

[0551] If the third device performs time-frequency adjustment to maintain time-frequency synchronization with the second device, the third device adjusts the sampling timing according to the third timing deviation Δt2-Δt1 and adjusts the local oscillator frequency according to the third frequency deviation Δf2-Δf1: that is, the sampling timing of the third device is advanced or delayed by the third timing deviation Δt2-Δt1, and the local oscillator frequency of the third device is increased or decreased by the third frequency deviation Δf2-Δf1.

[0552] If the second device performs time-frequency adjustment to maintain time-frequency synchronization with the third device, the second device adjusts the sampling timing according to the third timing deviation Δt1-Δt2 and adjusts the local oscillator frequency according to the third frequency deviation Δf1-Δf2: that is, the sampling timing of the third device is advanced or delayed by the third timing deviation Δt1-Δt2, and the local oscillator frequency of the third device is increased or decreased by the third frequency deviation Δf1-Δf2.

[0553] It should be noted that the above-mentioned "addition or subtraction", "advance or lag", "increase or decrease", specifically whether it is "addition" or "subtraction", "advance" or "lag", "increase" or "decrease", depends on the definition of the positive or negative sign of the sampling timing deviation or the local oscillator frequency deviation, and can be set according to the actual application situation, which is not elaborated here.

[0554] Example 2:

[0555] This embodiment is a supplement to Embodiment 1. In this embodiment, the fourth device sends the same signal to the second device and the third device.

[0556] In this embodiment, the first signal sent by the fourth device to the second device and the second signal sent by the fourth device to the third device are the same signal.

[0557] In this case, the first signal (or the second signal) is a wide beam signal that can cover the range of the second device and the third device, as shown in Figure 10. In step (13), the second signaling sent by the first device to the second device and the third signaling sent by the first device to the third device are the same. Since the second device and the third device receive the same signal, the measured sampling timing deviation and local oscillator frequency deviation are at the same time (the error caused by the different distances from the fourth device to the second device and from the fourth device to the third device is usually very small and can be ignored), and no additional processing is required.

[0558] Example 3:

[0559] This embodiment is a supplement to the embodiment 1. In this embodiment, as shown in FIG11 , the fourth device sends different signals to the second device and the third device.

[0560] In this embodiment, the first signal sent by the fourth device to the second device and the second signal sent by the fourth device to the third device are not the same signal.

[0561] Here, the first signal and the second signal are different in at least one of the three dimensions of time, frequency, and angle. In this case, in step (13), the second signaling sent by the first device to the second device and the third signaling sent by the first device to the third device are different in content.

[0562] In one embodiment, the first signal and the second signal are narrow beam signals, and the fourth device sends the first signal to the second device and the second signal to the third device in a time division manner. To ensure the performance of the sensing calibration, a time interval between the first signal and the second signal may be limited, that is, the time interval between the first signal and the second signal cannot exceed a certain range, which can be ensured by a timestamp, as shown in step (16).

[0563] In another embodiment, the signal sent by the fourth device is the same, but the second device and the third device have different behaviors in receiving the signal. For example, the fourth device sends signals (first signal and second signal) with a period of 10ms, the third device receives the signal (i.e., the second signal) every 10ms, and the second device receives the signal (i.e., the first signal) every 20ms. An application scenario of this embodiment is: for example, the clock stability of the base station is relatively high, and the calibration measurement can be performed for a longer time; while the clock stability of the UE is relatively poor, and the time interval of the calibration measurement should be set to be shorter.
