[0109] In the following, in conjunction with the accompanying drawings, a measurement quantity acquisition method, an operation execution method, an apparatus and a device provided by the embodiments of the present application are described in detail through some embodiments and their application scenarios.

[0110] Please refer to FIG3 , which is a flow chart of a method for obtaining a measurement value provided in an embodiment of the present application. As shown in FIG3 , the method includes the following steps:

[0111] Step 301: The first device measures the first signal sent by the second device to obtain target data;

[0112] Step 302: The first device performs a first operation, where the first operation includes at least one of the following:

[0113] sending the target data;

[0114] Perform at least one of time delay information compensation and Doppler information compensation based on the target data;

[0115] Perform at least one of sampling timing synchronization and local oscillator frequency synchronization based on the target data;

[0116] The target data includes a target measurement quantity, and the target measurement quantity is obtained by measuring the first signal sent by the second device;

[0117] The target measurement quantity is used to determine deviation information between the first device and the third device, where the deviation information includes at least one of the following: sampling timing deviation and local oscillator frequency deviation.

[0118] The above-mentioned second device is understood to be a reference station, which can specifically be a wireless access network device or a terminal. The above-mentioned third device can be one device in a device pair, which can specifically be a wireless access network device or a terminal. The above-mentioned first device can be another device in a device pair, which can specifically be a wireless access network device or a terminal. Among them, the above-mentioned device pair refers to a device pair whose sampling timing deviation or local oscillator frequency deviation needs to be calibrated. The device pair can both be terminals, or the receiver is a wireless access network device, or one is a terminal and the other is a wireless access network device. The above-mentioned reference station can be a reference station for calibration. For example: using a reference station for calibration, the time deviation or local oscillator frequency deviation between device pairs can be calibrated; in particular, it is suitable for situations where there is no line of sight (LOS) path between the device pairs. Typical application scenarios may include at least one of the following:

[0119] In the synaesthesia integration scenario, the sampling timing deviation and frequency deviation between the transmitter and receiver of the perception signal are calibrated.

[0120] Time and frequency synchronization between TRPs in communication scenarios.

[0121] The measurement may include determining time delay information or Doppler information of the first signal, and determining the target measurement value based on the time delay information or Doppler information.

[0122] The above-mentioned sending target data may be sending the above-mentioned target data to a third device or a fourth device, wherein the fourth device may be the second device, the third device, the first device, or other devices, or a network element of the core network (such as a perception function network element), or a CU in a 5G centralized unit (CU)-distributed unit (DU) architecture, etc.

[0123] The target measurement quantity may be a measurement quantity obtained by measuring a first signal sent by the second device to the first device. Furthermore, before the second device sends the first signal, the second device receives a second signal sent by a third device, where the first signal is sent later than the second signal is received. For example, as shown in Figure 4 , the third device sends the second signal to the second device, and the second device sends the first signal to the first device.

[0124] In some embodiments, the target measurement quantity can be determined by measuring, by the first device, a first signal sent by the second device, combined with information related to a second signal sent by a third device to the second device. The first device may pre-acquire information related to the second signal sent by the third device to the second device, such as information sent by the third device to the first device, or information sent by the fourth device to the first device. For example, the third device sends a second signal to the second device, and the second device sends a first signal to the first device a preset time after receiving the second signal, and the first device receives the first signal. In this way, the first device can extract the sampling timing deviation and local oscillator frequency deviation between the first and third devices. For example, the sampling timing deviation between the first and third devices can be determined based on the transmission time of the second signal and the reception time of the first signal, and the local oscillator frequency deviation between the first and third devices can be determined based on the frequency of the second signal and the frequency of the first signal. In this way, only the first device needs to perform measurements to extract the sampling timing deviation and local oscillator frequency deviation between the third and first devices. If the first device is a receiver of a perception signal in a synaesthesia scenario or a receiver in a communication scenario, there is no need to exchange measurements related to the sampling timing deviation and local oscillator frequency deviation, thereby significantly reducing signaling overhead in the calibration process.

[0125] The target measurement quantity used to determine the deviation information between the first device and the third device can be understood as the target measurement quantity including the deviation information between the first device and the third device, or the information included in the target measurement quantity can be used to calculate the deviation information between the first device and the third device.

[0126] The above-mentioned deviation information includes at least one of the following: sampling timing deviation, local oscillator frequency deviation; it can be understood that the above-mentioned deviation information between the first device and the third device may include at least one of the sampling timing deviation between the first device and the third device, and the local oscillator frequency deviation between the first device and the third device.

[0127] At least one of the delay information compensation and the Doppler information compensation based on the target data may be compensating the delay information of the perception signal based on the sampling timing deviation, or compensating the Doppler information of the perception signal based on the local oscillator frequency deviation.

[0128] At least one of the sampling timing synchronization and the local oscillator frequency synchronization performed based on the target data may be timing synchronization performed based on a sampling timing deviation or frequency synchronization performed based on a local oscillator frequency deviation.

[0129] In an embodiment of the present application, the above steps can be used to compensate for at least one of the delay information and the Doppler information, and at least one of the timing synchronization and the local oscillator frequency synchronization, so as to realize the calibration of the sampling timing deviation or the local oscillator frequency deviation between the third device and the first device, which is beneficial to improving the performance of perception or communication between the third device and the first device, and sending the target data can enable the device to use at least one of the sampling timing deviation and the local oscillator frequency deviation between the third device and the first device, support the calibration of the sampling timing deviation or the local oscillator frequency deviation between the third device and the first device, which is beneficial to improving the performance of perception or communication between the third device and the first device. In addition, since the deviation information includes the sampling timing deviation and the local oscillator frequency deviation, the device that obtains the deviation information can perform corresponding compensation or calibration, for example: it can be used to compensate or correct the perception measurement quantity or perception result in the synaesthesia integration scenario, or for the time-frequency synchronization between TRPs during multi-TRP coherent transmission in the communication scenario.

[0130] In addition, in the embodiment of the present application, since the second device can be a wireless access network device, an ordinary terminal or a customized terminal specifically used for calibration, it has the advantages of a larger coverage range and easier implementation. For example: the second device is a wireless access network device and can have a larger coverage range; the second device is an ordinary terminal which is more conducive to implementation and reduces complexity; and the second device is a customized terminal which can more accurately match the calibration requirements.

[0131] In an embodiment of the present application, the second device can provide calibrated measurement quantities for multiple links within its coverage area. Therefore, the first signal or the second signal can be configured on a per cell basis, which is simpler to implement and can save resources, such as time-frequency resources or power.

[0132] The application scenarios of the embodiments of the present application include but are not limited to applications in the synaesthesia integration scenario and applications in the communication scenario shown in Figures 5 and 6.

[0133] The following is an example of how to obtain the target measurement value in the embodiment of the present application:

[0134] As shown in FIG7 , the third device sends the second signal and the second device receives the second signal.

[0135] According to the signal configuration of the second signal, the sending time of the second signal is t1 and the carrier frequency is f1.

[0136] Since there are certain errors in the sampling clock and local oscillator frequency of each device, the third device sends the second signal according to the time t1 of its own local clock. The actual time is The third device generates a second signal with a carrier frequency of f1 based on its own frequency source. 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 third device according to its own frequency source is

[0137] As shown in Figure 7, let the time deviation between the local clock of the second device and the local clock of the third device be Δt1, that is, the sampling timing deviation of the second device relative to the third device. Then when the third device sends the second signal, the time of the local clock of the second device is

[0138] Assume that the signal propagation delay of the second signal from the third device to the second device is τ1. Then when the second device receives the second signal, the time of the local clock of the second device is

[0139] In addition, let the local oscillator frequency deviation between the local oscillator frequency of the second device and the local oscillator frequency of the third device be Δf1, that is, the local oscillator frequency deviation of the second device relative to the third device. Then the local oscillator signal frequency of the second device is Therefore, there is

[0140] Assume that the Doppler frequency caused by the relative motion between the second device and the third device is f d1 , before the second device receives the second signal, the carrier frequency of the second signal is modulated by the Doppler frequency and becomes Will Substituting, the carrier frequency of the second signal is modulated by the Doppler frequency and is

[0141] The second device sends a first signal, and the first device receives the first signal:

[0142] The second device receives the second signal at its own local oscillator frequency The second signal is down-converted to obtain a baseband signal frequency of -Δf1+f d1 , which includes the influence of the local oscillator frequency deviation Δf1 between the second device and the third device.

[0143] Afterwards, after the second device receives the second signal, it will 1,2 After that, the first signal is sent to the first device. Therefore, when the second device sends the first signal, the time of the local clock of the second device is

[0144] The baseband frequency of the first signal is -Δf1+f d1, therefore, the LO frequency of the second device After up-conversion, the carrier frequency of the first signal is

[0145] Optionally, when the second device performs up-conversion on the first signal, the second device uses the local oscillator frequency Add a frequency deviation Δf 1,2 The local oscillator signal then up-converts the first signal, i.e., the second device uses The first signal is up-converted by the local oscillator frequency. Thus, the carrier frequency of the first signal is It should be noted that Δf in the following discussion 1,2 Can be 0.

[0146] Since the sampling clock and local oscillator frequency of each device have certain errors, let the time deviation between the local clock of the first device and the local clock of the second device be Δt2, that is, the sampling timing deviation of the first device relative to the second device. Therefore, here is the t1 of the local clock of the first device. Then when the second device sends the first signal, the time of the local clock of the first device is In addition, let the local oscillator sampling timing deviation between the first device and the second device be Δf2, which is the local oscillator frequency deviation of the first device relative to the second device. The actual frequency of the local oscillator signal with a frequency of f1 generated by the first device based on its own frequency source is

[0147] Assume that the signal propagation delay of the first signal from the second device to the first device is τ2. When the first device receives the first signal, the time of the local clock of the first device is Since the configured sending time of the second signal is t1, the first device uses the time of its local clock As the sending time of the second signal, the total delay information extracted from the sending of the second signal to the receiving of the first signal is -Δt1+τ1+Δt 1,2 -Δt2+τ2.

[0148] In addition, let the Doppler frequency caused by the relative motion between the first device and the second device be f d2 , before the first device receives the first signal, the carrier frequency of the first signal is modulated by the Doppler frequency and becomes Since the local oscillator frequency of the first device is Therefore, the result of adding the Doppler frequency extracted by the first device to the local oscillator frequency deviation is f d1 +f d2 +Δf 1,2 -Δf1-Δf2.

[0149] The sampling timing deviation and local oscillator frequency deviation of the first device relative to the third device are extracted as follows:

[0150] In some cases, the positions and movement speeds of the second device, the third device, and the first device are known, then the above τ1, τ2, and f d1 and f d2 It can be obtained through the position relationship and relative movement speed between the three devices and is thus known.

[0151] In addition, the time delay Δt between the second device receiving the second signal and the second device sending the first signal is 1,2 is known to the configuration, and the frequency deviation Δf of the carrier frequency of the first signal transmitted by the second device relative to the carrier frequency of the second signal received by the second device 1,2 The configuration is also known.

[0152] Therefore, the total delay information -Δt1+τ1+Δt 1,2 -Δt2+τ2 extracts Δt1+Δt2, which is the sampling timing deviation of the first device relative to the third device. And the Doppler frequency superimposed on the local oscillator frequency deviation f can be extracted from the first device. d1 +f d2 +Δf 1,2 Extract Δf1+Δf2 from -Δf1-Δf2 and record it as the local oscillator frequency deviation of the first device relative to the third device.

[0153] The sampling timing deviation and local oscillator frequency deviation of the first device relative to the third device can then be used to compensate for the signals sent and received between the third device and the first device:

[0154] For example, in a synaesthesia integration scenario, after obtaining a perception result through the third device and the first device, the perception measurement quantity or the perception result is compensated with Δt1+Δt2 and Δf1+Δf2 respectively, thereby obtaining the correct time delay and Doppler of the path reflected by the perceived target.

[0155] For example, in a cell-free scenario, the sampling timing and local oscillator frequency of the TRP are corrected using Δt1+Δt2 and Δf1+Δf2 respectively.

[0156] It should be noted that the above embodiment is only an example of the situation shown in Figure 7. In the embodiment of the present application, the positive and negative signs of Δt1, Δt2, Δf1 and Δf2 in the above embodiment depend on the definition of relative delay and relative local oscillator frequency deviation in the specific implementation process. The compensation values ​​obtained by relevant professionals based on the above analysis are other situations. For example: the sampling timing deviation of the first device relative to the third device is Δt1-Δt2, -Δt1+Δt2 or -Δt1-Δt2, and the local oscillator frequency deviation of the first device relative to the third device is Δf1-Δf2, -Δf1+Δf2 or -Δf1-Δf2), which will not be elaborated on.

[0157] As an optional implementation manner, the target measurement quantity includes at least one of the following:

[0158] Sampling timing deviation between the first device and the third device, local oscillator frequency deviation between the first device and the third device, I-channel data, Q-channel data, channel matrix, spectrum information, delay information, and Doppler information.

[0159] The sampling timing offset between the first device and the third device may be a sampling timing offset of the first device relative to the third device, or a sampling timing offset of the third device relative to the third device.

[0160] The local oscillator frequency deviation between the first device and the third device may be a local oscillator frequency deviation of the first device relative to the third device, or a local oscillator frequency deviation of the third device relative to the first device.

[0161] The above-mentioned target measurement quantities include the I-channel data, Q-channel data, channel matrix, spectrum information, delay information, and Doppler information obtained by measuring the first signal sent by the second device.

[0162] The channel matrix may be a channel estimation result obtained by methods such as least squares estimation (LS) and minimum mean squared error (MMSE), or may be a result of noise suppression on the channel estimation result, such as noise suppression by discrete Fourier transform (DFT).

[0163] The above spectrum information may include at least one of the following: delay spectrum, Doppler spectrum, and delay-Doppler spectrum.

[0164] The delay information may refer to a measurement value of a total delay from the sending of the second signal to the receiving of the first signal extracted by the first device;

[0165] The Doppler information may refer to a measurement value of a total frequency deviation between a carrier frequency of a second signal sent by a third device and a carrier frequency of a first signal received by the first device, which is extracted by the first device.

[0166] Among them, at least one of the I-channel data, Q-channel data, channel matrix, spectrum information, delay information, and Doppler information included in the above-mentioned target measurement quantity can be used to calculate the sampling timing deviation or local oscillator frequency deviation between the above-mentioned first device and the third device.

[0167] As an optional implementation manner, the sampling timing deviation between the first device and the third device includes:

[0168] a sampling timing offset between the first device and the third device determined by the first device based on a transmission time of a local clock of the first device relative to a second signal and a reception time of the first signal by the first device;

[0169] or,

[0170] The local oscillator frequency deviation between the first device and the third device includes:

[0171] A local oscillation frequency deviation between the first device and the third device determined by the first device based on the frequency of the local oscillation signal generated by the frequency source of the first device and the frequency of the first signal detected by the first device;

[0172] The sampling timing deviation between the first device and the third device determined by the first device based on the local clock of the first device relative to the sending time of the second signal and the receiving time of the first device receiving the first signal can be determined based on the local clock of the first device relative to the sending time of the second signal and the receiving time of the first device receiving the first signal. The sampling timing deviation between the first device and the third device is then extracted based on the total delay information. For example, in the case shown in Figure 7, the total delay is -Δt1+τ1+Δt 1,2 -Δt2+τ2, so that Δt1+Δt2 can be extracted from the total delay, which is the sampling timing deviation of the first device relative to the third device.

[0173] The local oscillator frequency deviation between the first device and the third device determined based on the frequency of the local oscillator signal generated by the frequency source of the first device and the frequency of the first signal detected by the first device can be determined by superimposing the Doppler frequency on the local oscillator frequency deviation based on the frequency of the local oscillator signal generated by the frequency source of the first device and the frequency of the first signal detected by the first device, and then extracting the local oscillator frequency deviation between the first device and the third device from the Doppler frequency superimposed on the local oscillator frequency deviation. For example, in the case shown in FIG7 , the Doppler frequency superimposed on the local oscillator frequency deviation is f d1 +f d2 +Δf 1,2 -Δf1-Δf2, so that Δf1+Δf2 can be extracted from the Doppler frequency superimposed on the local oscillator frequency deviation, which is recorded as the local oscillator frequency deviation of the first device relative to the third device.

[0174] The second signal is a signal sent by the third device to the second device before the first signal is sent.

[0175] The frequency of the local oscillator signal generated by the frequency source of the first device is the frequency of the local oscillator signal generated by the frequency source of the first device based on the ideal (or configured) carrier frequency of the second signal. The ideal (or configured) carrier frequency of the second signal is not the actual carrier frequency of the second signal because the actual carrier frequency of the second signal is generated by the frequency source of the third device based on the ideal (or configured) carrier frequency of the second signal.

[0176] The specific determination process can be referred to the example of the situation shown in FIG7 , which will not be described in detail here.

[0177] In one of the aforementioned optional embodiments, a sampling timing offset between the first device and the third device can be accurately determined based on a transmission time of the local clock of the first device relative to the second signal and a reception time of the first signal by the first device. A local oscillator frequency offset between the first device and the third device can be accurately determined based on a frequency of a local oscillator signal generated by a frequency source of the first device and a frequency of the first signal detected by the first device.

[0178] As an optional implementation manner, the target data sent by the first device further includes at least one of the following:

[0179] Related information of the first signal, related information of the second signal, related information of the second device, related information of the third device, and related information of the first device.

[0180] The relevant information of the first signal may include at least one of the following:

[0181] The link information of the first signal, the identification information of the first signal, and the timestamp of the first signal.

[0182] The link information of the first signal may be a link ID of the first device receiving the first signal, and the timestamp of the first signal is used to indicate the time when the first signal is received.

[0183] The relevant information of the second signal may include at least one of the following:

[0184] link information of the second signal, and identification information of the second signal.

[0185] The link information of the second signal may be a link ID for the second device to receive the second signal.

[0186] The relevant information of the first device may include at least one of the following:

[0187] The identification information of the first device, the location information of the first device, the speed information of the first device, the information related to the timing adjustment of the first device during the reception of the second signal, and the information related to the local oscillator frequency adjustment of the first device during the reception of the second signal.

[0188] The timing adjustment related information may include the timing adjustment result, timing adjustment amplitude, or indication information indicating whether a timing adjustment is performed. The local oscillator frequency adjustment related information may include the local oscillator frequency adjustment result, local oscillator frequency adjustment amplitude, or indication information indicating whether a local oscillator frequency adjustment is performed.

[0189] The relevant information of the second device may include at least one of the following:

[0190] Identification information of the second device, location information of the second device, and speed information of the second device.

[0191] The relevant information of the third device may include at least one of the following:

[0192] Identification information of the third device, location information of the third device, and speed information of the third device.

[0193] In one of the above optional embodiments, since the above target data also includes relevant information of the first signal, relevant information of the second signal, relevant information of the second device, relevant information of the third device or relevant information of the first device, the device receiving the target data can have more information reference when performing compensation or synchronization, so as to improve the effect of compensation or synchronization.

[0194] As an optional implementation manner, performing at least one of delay information compensation and Doppler information compensation based on the target data includes at least one of the following:

[0195] The first device compensates, based on a sampling timing deviation between the third device and the first device, for delay information of the perception signal sent by the third device;

[0196] The first device compensates, based on a local oscillator frequency deviation between the third device and the first device, for Doppler information of the sensing signal sent by the third device;

[0197] or,

[0198] The performing at least one of sampling timing synchronization and local oscillator frequency synchronization based on the target data includes at least one of the following:

[0199] The first device performs timing synchronization with the third device based on a sampling timing deviation between the third device and the first device;

[0200] The first device performs frequency synchronization with the third device based on a local oscillator frequency deviation between the third device and the first device.

[0201] For example, in the scenario shown in Figure 7, if the third device sends the sensing signal and the first device receives it, Δt1+Δt2 is added to the delay information, and Δf1+Δf2 is added to the Doppler information. For example, Δt1+Δt2 is added or subtracted from the measured delay value to obtain the accurate value of the signal propagation delay, and Δf1+Δf2 is added or subtracted from the measured Doppler value to obtain the accurate value of the Doppler frequency.

[0202] For another example, in the scenario shown in Figure 7, if the first device transmits the sensing signal and the third device receives it, Δt1+Δt2 should be added to the delay information, and Δf1+Δf2 should be added to the Doppler information. For example, Δt1+Δt2 can be added or subtracted from the measured delay value to obtain the accurate value of the signal propagation delay, and Δf1+Δf2 can be added or subtracted from the measured Doppler value to obtain the accurate value of the Doppler frequency.

[0203] For another example: In a Cell-free scenario, in order to synchronize TRPs and achieve coherent transmission of multiple TRPs, if the first device performs time-frequency adjustment to maintain time-frequency synchronization with the third device, the first device adjusts the sampling timing according to Δt1+Δt2 and adjusts the local oscillator frequency according to Δf1+Δf2. For example, the sampling timing of the first device is advanced or delayed by Δt1+Δt2, and the local oscillator frequency of the first device is increased or decreased by Δf1+Δf2. If the third device performs time-frequency adjustment to maintain time-frequency synchronization with the first device, the third device adjusts the sampling timing according to Δt1+Δt2 and adjusts the local oscillator frequency according to Δf1+Δf2. For example, the sampling timing of the first device is advanced or delayed by Δt1+Δt2, and the local oscillator frequency of the first device is increased or decreased by Δf1+Δf2.

[0204] It should be noted that the specific addition or subtraction, advance or lag, increase or decrease described above depends on the definition of the sign of the sampling timing deviation or the local oscillator frequency deviation. Specific settings can be made based on actual application conditions and are not detailed here.

[0205] In one of the above optional implementations, the delay information or Doppler information of the perception signal can be compensated to improve the perception performance of the device, and timing synchronization or frequency synchronization with the third device can be achieved to improve the communication performance of the device.

[0206] As an optional implementation manner, the first device sends target data, including at least one of the following:

[0207] The first device sends the target data to the third device;

[0208] The first device sends the target data to a fourth device.

[0209] Sending the target data to the third device may cause the third device to perform at least one of the following:

[0210] The third device compensates for delay information of the perception signal sent by the first device based on a sampling timing deviation between the third device and the first device;

[0211] The third device performs timing synchronization with the first device based on a sampling timing deviation between the third device and the first device;

[0212] The third device compensates for Doppler information of the sensing signal sent by the first device based on a local oscillator frequency deviation between the third device and the first device;

[0213] The third device performs frequency synchronization with the first device based on a local oscillator frequency deviation between the third device and the first device.

[0214] Sending the target data to the fourth device may cause the fourth device to perform at least one of the following:

[0215] The fourth device compensates for delay information of the perception signal transmitted between the third device and the first device based on the sampling timing deviation between the third device and the first device.

[0216] The fourth device compensates for Doppler information of the sensing signal transmitted between the third device and the first device based on a local oscillator frequency deviation between the third device and the first device.

[0217] In one of the above optional implementations, by sending target data to the third device or the fourth device, the third device or the fourth device may be compensated or synchronized to improve the perception or communication performance of the third device or the fourth device.

[0218] As an optional implementation, the method further includes:

[0219] The first device receives first signaling, where the first signaling includes at least one of the following:

[0220] an instruction to request that a calibration be performed;

[0221] a time offset between a time when the second device sends the first signal and a time when the second device receives the second signal;

[0222] a frequency deviation of a carrier frequency of the first signal sent by the second device relative to a carrier frequency of the second signal received by the second device;

[0223] Configuration information of the first signal.

[0224] The above calibration may refer to calibration through at least one of delay information compensation, Doppler information compensation, timing synchronization or frequency synchronization.

[0225] The time offset between the time when the second device sends the first signal and the time when the second device receives the second signal refers to the interval between the time when the second device sends the first signal and the time when the second device receives the second signal, as shown in FIG7 . 1,2 .

[0226] The frequency deviation of the carrier frequency of the first signal sent by the second device relative to the carrier frequency of the second signal received by the second device may be the local oscillator frequency deviation between the local oscillator frequency of the second device and the local oscillator frequency of the third device, such as Δf in the case shown in FIG7 . 1,2 .

[0227] In the above optional implementation manner, since the above time deviation or frequency deviation is configured, the first device can more accurately calculate the sampling timing deviation or local oscillator frequency deviation between the first device and the third device based on the above time deviation or frequency deviation.

[0228] The configuration information of the first signal is used to configure the first signal. In some embodiments, the configuration information of the first signal includes at least one of the following:

[0229] signal configuration of the first signal, an index of the first signal, indication information for activating at least one resource set, indication information for deactivating at least one resource set, and an identifier of a communication reference signal serving as the first signal;

[0230] The at least one resource set is a resource set corresponding to the first signal.

[0231] The index of the first signal may be an index from a preconfigured or protocol-agreed list. For example, multiple sets of signals may be preconfigured for performing time-frequency calibration, where the time-frequency calibration includes at least one of delay compensation, Doppler compensation, timing synchronization, or frequency synchronization. During a calibration, the fourth device determines a set of signals for calibration based on calibration requirements and sensing capability information of the second, third, and first devices. The signal identifiers may be used to indicate which set of signals to enable as the first signal.

[0232] The above-mentioned indication information for activating at least one resource set may be a pre-configured plurality of resource sets, wherein the indication information activates at least one resource set in these resource sets, and the signals corresponding to these resource sets constitute the first signal. For example, a resource pool is pre-configured, and the resource pool contains multiple resource sets (Resource Sets). During the execution of a calibration, the fourth device selects one or more Resource Sets from the resource pool based on the calibration requirements, the perception capability information of the second device, the third device, and the first device, and then activates these Resource Sets through an activation instruction, and the signals corresponding to these Resource Sets constitute the first signal.

[0233] The indication information for deactivating at least one resource set may be pre-configured multiple resource sets, and the indication information deactivates at least one resource set in these resource sets, that is, the signals corresponding to these resources are not used to constitute the first signal.

[0234] It should be noted that, in some embodiments, when the above-mentioned indication information for activating at least one resource set is not included, and only the above-mentioned indication information for deactivating at least one resource set is included, the resource set that is not deactivated is activated by default and is used to constitute the first signal.

[0235] The identifier of the communication reference signal as the first signal is used to indicate the communication reference signal as the first signal, so that time-frequency calibration can be achieved based on the communication reference signal.

[0241] Bandwidth: This parameter is inversely proportional to the range resolution and can be obtained by c / 2Δd, where Δd is the range resolution (perception requirement) and c is the speed of light.

[0242] Burst duration: This parameter is inversely proportional to the rate resolution (a perception requirement). It is the time span of the perception signal, mainly for calculating the Doppler frequency deviation. This parameter can be calculated by c / (2f c Δv) is calculated; where Δv is the velocity resolution; f c is the carrier frequency of the sensing signal;

There are two types of time resources: one is a one-time time resource, for example, one symbol sends an omnidirectional perception signal; the other is a non-one-time time resource, such as multiple groups of periodic time resources or discontinuous time resources (which may include start time and end time). Each group of periodic time resources sends a perception signal in the same direction, and different groups of periodic time resources have different beam directions.

[0483] Step 3: Signal configuration for the first signal and the second signal.

[0484] After determining the second device (reference station), the fourth device sends a second signaling to the second device, sends a third signaling to the third device, and sends a first signaling to the first device to instruct the execution of the perception calibration described in this application.

[0499] The above calibration requirements include at least one of the following: the accuracy of sampling timing deviation and the accuracy of local oscillator frequency deviation.

[0500] Step 4. Measurement configuration for the first device.

[0501] In this embodiment, the third device transmits a second signal, the second device receives the second signal and transmits a first signal based on the received second signal, and the first device receives the first signal. Therefore, the measurement in this embodiment primarily involves the first device measuring the first signal. To perform the measurement of the first signal, the fourth device needs to configure the first device for measurement.

[0502] The fourth device sends the measurement configuration to the first device,

[0503] The fourth device sends a measurement configuration to the second device, including at least one of the following:

[0504] Configuration of the measured quantities to be measured and reported, and configuration of the reporting time.

[0505] The amount obtained by measuring the first signal is recorded as a target measurement amount, including at least one of the following:

[0506] I-channel data;

[0507] Q-channel data;

[0508] 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);

[0509] Delay spectrum, Doppler spectrum, or delay-Doppler spectrum;

[0510] Delay information: This mainly refers to the total delay information from the sending of the second signal to the receiving of the first signal extracted by the first device; that is, -Δt1+τ1+Δt in the case shown in Figure 7 1,2 -Δt2+τ2;

[0511] Doppler information: This mainly refers to the result of superimposing the Doppler frequency extracted by the first device on the local oscillator frequency deviation; that is, f in the case shown in Figure 7 d1 +f d2 +Δf 1,2 -Δf1-Δf2;

[0512] Sampling timing deviation: the sampling timing deviation of the first device relative to the third device extracted by the first device, i.e., Δt1 + Δt2 in the case shown in FIG7 ;

[0513] Local oscillator frequency deviation: the local oscillator frequency deviation of the first device relative to the third device extracted by the first device, that is, Δf1+Δf2 in the case shown in FIG7 .

[0514] Indicates the time configuration for measurement reporting, including at least one of the following:

[0515] Periodic reporting: reporting the above measurement quantity according to a specified time offset or period;

[0516] Semi-persistent reporting: reports the above measurement values ​​at a specified period after receiving the activation command;

[0517] Aperiodic reporting: reporting the above measurement quantity once at a specified time or when preset conditions are met.

[0518] In some typical implementations, if the first device has strong computing power and can complete all operations of the method described in this application, the first device can report the measured value of the target measurement delay information, Doppler information, target sampling timing deviation or the above-mentioned frequency deviation.

[0519] In some typical implementations, if the computing power of the first device is insufficient to obtain the target measurement variables: delay information, Doppler information, target sampling timing deviation, or target local oscillator frequency deviation, the first device may report the target measurement variables: I-channel data, Q-channel data, channel matrix, delay spectrum, Doppler spectrum, or delay-Doppler spectrum. The device receiving the target measurement variables (the fourth device or the third device) then performs computations to obtain the corresponding measured values ​​of the delay information, Doppler information, target sampling timing deviation, or the aforementioned frequency deviation.

[0520] Step 5. The first device obtains the location information and / or speed information of the second device and the third device. This includes at least one of the following:

[0521] In a case where the target measurement amount includes a target sampling timing deviation, the first device further obtains location information of the second device and the third device;

[0522] In a case where the target measurement variable includes a target local oscillator frequency deviation, the first device further obtains speed information of the second device and the third device.

[0523] When the above situation does not occur, the first device does not need to obtain the location information or speed information of the second device and the third device.

[0524] Obviously, when the first device obtains the location information of the second device and the third device, the first device also obtains its own location information; when the first device obtains the speed information of the second device and the third device, the first device also obtains its own speed information.

[0525] Optionally, the method for the first device to obtain the location information and speed information of the second and third devices may be: receiving corresponding information content sent by the fourth device. It should be noted here that in step 2, the fourth device has already obtained the location information or speed information of the second and third devices.

[0526] Step 6: The first device reports the measurement.

[0527] The content reported by the first device includes at least one of the following:

[0528] a link identifier (ID) indicating that the third device sends the second signal, the second device receives the second signal and sends the second signal, and the first device receives the first signal, or IDs of the second device, the third device, and the first device;

[0529] The ID of the second signal;

[0530] ID of the first signal;

[0531] location information of the first device;

[0532] speed information of the first device;

[0533] Timestamp: used to indicate the time when the first signal is received;

[0534] A measured value of a first measured quantity.

[0535] Information related to timing adjustment or local oscillator frequency adjustment performed by the first device during reception of the first signal.

[0536] The device receiving the measurement report of the first device may be: the fourth device or the third device.

[0537] The first device performs a measurement and reports the measurement to the fourth device. In this case, the fourth device calculates the final sampling timing deviation or local oscillator frequency deviation between the first device and the third device. The fourth device then sends the sampling timing deviation or local oscillator frequency deviation between the first device and the third device to the third device or the first device.

[0538] The first device reports the measurement to the third device. This can be done in the following two situations:

[0539] The third device calculates a final sampling timing deviation or local oscillator frequency deviation between the first device and the third device. Optionally, the third device sends the sampling timing deviation or local oscillator frequency deviation to the first device.

[0540] The first measurement quantity sent by the first device to the third device directly includes a sampling timing deviation or a local oscillator frequency deviation between the first device and the third device.

[0541] Step 7. Use of calibration information.

[0542] In the synaesthesia scenario, when performing the subsequent perception task:

[0543] If the third device sends the perception signal and the first device receives the perception signal, Δt1+Δt2 should be compensated to the delay information and Δf1+Δf2 should be compensated to the Doppler information: that is, add or subtract Δt1+Δt2 from the measured delay value to obtain the accurate value of the signal propagation delay, and add or subtract Δf1+Δf2 from the measured Doppler value to obtain the accurate value of the Doppler frequency.

[0544] If the first device sends the perception signal and the third device receives the perception signal, Δt1+Δt2 should be compensated to the delay information and Δf1+Δf2 should be compensated to the Doppler information: that is, add or subtract Δt1+Δt2 from the measured delay value to obtain the accurate value of the signal propagation delay, and add or subtract Δf1+Δf2 from the measured Doppler value to obtain the accurate value of the Doppler frequency.

[0545] In the Cell-free scenario, to synchronize TRPs and achieve coherent transmission of multiple TRPs, the following options are available:

[0546] If the first device performs time-frequency adjustment to maintain time-frequency synchronization with the third device, the first device adjusts the sampling timing according to Δt1+Δt2 and adjusts the local oscillator frequency according to Δf1+Δf2: that is, the sampling timing of the first device is advanced or delayed by Δt1+Δt2, and the local oscillator frequency of the first device is increased or decreased by Δf1+Δf2;

[0547] If the third device performs time-frequency adjustment to maintain time-frequency synchronization with the first device, the third device adjusts the sampling timing according to Δt1+Δt2 and adjusts the local oscillator frequency according to Δf1+Δf2: that is, the sampling timing of the first device is advanced or delayed by Δt1+Δt2, and the local oscillator frequency of the first device is increased or decreased by Δf1+Δf2.

[0548] The above-mentioned "add or subtract", "advance or lag", "increase or decrease", specifically whether it is "add" or "subtract", "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.
