[0151] Instantaneous channel correlation values ​​corresponding to two TRSs in each TRS pair in at least one TRS pair;

[0152] The average value of the instantaneous channel correlation values ​​corresponding to the two TRSs in at least one TRS pair;

[0153] The variance of the instantaneous channel correlation values ​​corresponding to the two TRSs in at least one TRS pair.

[0154] Since the two TRSs in another TRS pair are transmitted at different time points, due to the change between the channels between the first device and the second device and the similarity of the transmission parameters of the two TRSs in a TRS pair, the correlation between the two TRSs can reflect the change in the channel. Here, the transmission parameters of the two TRSs in a TRS pair may include but are not limited to the transmission power, transmission beam and / or transmission sequence of the TRS. In some embodiments, the first device broadcasts the second information to the second device.

[0155] In some embodiments, the first device unicasts the second information to the second device.

[0156] In some embodiments, the first device multicasts the second information to the second device.

[0157] In some embodiments, the first device sends an RRC message, MAC signaling, or downlink control information (DCI) containing the second information to the second device.

[0158] In some embodiments, the second information may be carried in a system information block (SIB).

[0159] The first device sends the second information, and the second device can receive the second information.

[0160] In some embodiments, the second information may further include a fifth indication. For example, the fifth indication may be used to indicate the channel type of the first channel. For example, the measured first channel may be a fading channel and / or a Gaussian channel. For example, the Gaussian channel may include, but does not include, an additive Gaussian channel.

[0161] In some other embodiments, the second information may further include a sixth indication. Exemplarily, the sixth indication is used to indicate the frequency domain location where the first information is sent.

[0162] In some embodiments, if the first channel is a fading channel, the second information may or may not include the first indication. For example, the first device and the second device may agree to measure one or more TRS pairs closest to the first moment in the time domain. The TRS pairs measured by the second device may be agreed upon by a protocol.

[0163] In some embodiments, if the first channel is a Gaussian channel, the second information may include or not include the first indication. For example, since the first channel is a Gaussian channel, the first device may add Gaussian noise to the transmitted TRS based on a Gaussian model to obtain a reference result. In this case, the first device may determine a statistically based reference result based on the Gaussian noise, regardless of which specific TRS the first device measures.

[0164] S2102: The second device measures at least one TRS pair to obtain a measurement result.

[0165] In some embodiments, the second device measures one or more TRS pairs according to the second information to obtain a measurement result.

[0166] Exemplarily, the second device determines the number of TRS pairs to be measured according to the first indication.

[0167] Also exemplarily, the second device determines the type of measurement result that needs to be reported based on the second indication, and the type of measurement result may include but is not limited to any one of the above-mentioned channel instantaneous correlation values ​​corresponding to the two TRSs, the average value of the channel instantaneous correlation values ​​corresponding to the two TRSs in at least one TRS pair, and / or the variance of the channel instantaneous correlation values ​​corresponding to the two TRSs in at least one TRS pair.

[0168] In some embodiments, the second device measures the TRS to obtain a TRS measurement value, which may include but is not limited to a TRS phase, a TRS reception power and / or a TRS reception strength, etc., measured by the first device.

[0169] S2103: The second device sends the first information.

[0170] In some embodiments, the second device sends the first information to the first device.

[0171] In some embodiments, the second device broadcasts, multicasts, or unicasts the first information to the first device.

[0172] In some embodiments, the first information is used to indicate a measurement result of at least one tracking reference signal (TRS) pair.

[0173] In some embodiments, the first device sends the first information according to a lower time corresponding to the fourth indication.

[0174] In some embodiments, the first information may be a numerical value of a measurement result. In this case, the first device obtains the measurement result upon receiving the first information.

[0175] In some embodiments, the first information may be an index of the measurement result. In this case, after receiving the index, the first device searches for the measurement result based on the corresponding relationship between the index and the measurement result.

[0176] S2104: The first device obtains a reference result of the first channel.

[0177] In some embodiments, the reference result of the first channel may be understood as an ideal result of the channel quality of the first channel.

[0178] In some embodiments, the reference result may be a result of comparing a channel instantaneous correlation value of a TRS pair close to the first channel, or a mean value or a true value of the variance of the instantaneous correlation.

[0179] Exemplarily, the first device may estimate a reference result of the first channel according to the transmission parameters of the TRS.

[0180] Exemplarily, the first device may calculate a reference result according to a transmission phase of the TRS, a Doppler spectrum effect, and / or a channel type of the first channel.

[0181] In some embodiments, the type of the reference result depends on the type of the measurement result.

[0182] In some embodiments, when the channel type of the first channel is a fading channel, the at least one TRS pair is one or more TRS pairs configured on the first channel with the smallest time domain spacing from the first moment.

[0183] In some embodiments, when the channel type of the first channel is a fading channel, an ideal value of a channel instantaneous correlation value of each TRS pair is determined based on a transmission parameter of at least one TRS pair and a channel model;

[0184] A reference result of a fading channel is determined according to an ideal value of a channel instantaneous correlation value of at least one TRS pair.

[0185] For example, in this manner, the channel correlation values ​​of two TRSs in a TRS pair may be calculated according to the following formula.

[0186] c(t, Δt) is the instantaneous correlation of the channel.

[0187] t may be the sending time of the first TRS sent in a TRS pair.

[0188] Δt may be the time interval between the transmission times of two TRSs in a TRS pair.

[0189] N may be the number of subcarriers occupied when a TRS is transmitted.

[0190] h n (t) may be the measured value of the TRS sent on the nth subcarrier at time t.

[0191] h n (t+Δt) may be a measurement value of the TRS sent at time t+Δt on the nth subcarrier.

[0192] Can be h n The conjugate of (t).

[0193] In some other embodiments, when the measurement result is the channel instantaneous correlation value of two TRSs in each TRS pair of at least one TRS pair of the first channel, an ideal value of the channel instantaneous correlation value of the TRS pair is determined as the reference result of the fading channel.

[0194] In some other embodiments, when the measurement result is an average of channel instantaneous correlation values ​​corresponding to two TRSs in at least one TRS pair, the average of ideal values ​​of channel instantaneous correlation values ​​of each TRS pair is determined as a reference result of the fading channel.

[0195] In some other embodiments, when the measurement result is the variance of the channel instantaneous correlation values ​​of two TRSs in each TRS pair in at least one TRS pair of the first channel, the variance of the channel instantaneous correlation values ​​of each TRS pair is determined as a reference result of the fading channel.

[0196] In some embodiments, a reference result of the fading channel is determined based on a Bessel function and a time interval between two TRSs of at least one TRS pair.

[0197] In some embodiments, different test sets may be set when performing an accuracy test on a measurement result, and the different test sets may correspond to different test time periods or different test frequency spectra.

[0198] The correlation between the reference results of the fading channels of different test sets may conform to a Bessel function.

[0199] Exemplarily, if a reference result of a fading channel is determined according to a Bessel function, one test set corresponds to one reference result.

[0200] In the embodiment of the present disclosure, the reference result can be obtained by substituting the two TRSs of a TRS pair and the corresponding Doppler spectrum spreading mode into the Bessel function. The Doppler spectrum spreading mode may include but is not limited to U-shape Doppler spread spectrum.

[0201] In some other embodiments, when the channel type of the first channel is an additive Gaussian channel, a reference result is obtained according to transmission parameters of at least one TRS pair and additive Gaussian noise.

[0202] In some embodiments, the transmission parameters of the TRS pair may include the transmission phase of each TRS in the TRS pair, etc. By adding noise to the transmitted TRS using an additive Gaussian model, a reference result after adding random Gaussian noise can be obtained.

[0203] S2105: Determine the accuracy of the measurement result based on the difference between the reference result and the measurement result.

[0204] In some embodiments, the numerical value of the measurement result included in the first information can be obtained by directly subtracting the measurement result from the reference result to obtain a difference between the measurement result and the difference result. The difference value reflects the accuracy of the measurement result. For example, the magnitude of the difference value is positively correlated with the accuracy.

[0205] In some embodiments, the index of the measurement result included in the first information can be used to obtain the value of the measurement result through index query, and then the difference between the measurement result and the differential result can be calculated to obtain the differential value. Alternatively, after querying the corresponding relationship to determine the index of the reference result, the index difference between the measurement result and the reference result is compared. The index difference represents the differential value. For example, a larger index difference can be considered to be a larger differential value, that is, the size of the index difference is positively correlated with the size of the differential value.

[0207] S3101: Send the second information.

[0231] As shown in FIG4 , an embodiment of the present disclosure provides a measurement result processing method, which is executed by a second device. The method may include:

[0232] S4101: Receive the second information.

[0233] In some embodiments, the second information is used by the second device to obtain a measurement result.

[0234] In some embodiments, the second information may be configuration information of the TRS.

[0235] In some embodiments, the second information may be an SIB, an RRC message, a MAC message, or a DCI.

[0242] It is worth noting that S4101 is an optional step. For example, the configuration information of the TRS may be determined by a protocol.

[0243] S4102: Measure at least one tracking reference signal TRS pair to obtain a measurement result.

[0244] In some embodiments, at least one TRS pair is measured according to the second information to obtain a measurement result.

[0245] The type of measurement result includes at least one of the following:

[0246] Instantaneous channel correlation values ​​corresponding to two TRSs in each TRS pair in at least one TRS pair;

[0247] The average value of the instantaneous channel correlation values ​​corresponding to the two TRSs in at least one TRS pair;

[0248] The variance of the instantaneous channel correlation values ​​corresponding to the two TRSs in at least one TRS pair.

[0249] S4103: Send the first message.

[0250] In some embodiments, the first device sends the first information to the second device.

[0251] In some embodiments, the first device sends a measurement report including the first information to the second device.

[0252] The first information is used to indicate a measurement result of at least one TRS pair.

[0253] The difference between the measurement result and the reference junction of the first channel is used by the first device to determine the accuracy of the measurement result.

[0254] In view of this, an embodiment of the present disclosure provides an information processing method to enable a core network to authorize disclosure of UE location information in perception context information.

[0255] There are two options for testing TDCP accuracy over fading channels:

[0256] Method 1: Compare the difference values ​​of the channel instantaneous correlation values;

[0257] Method 2: Calculate the channel correlation value difference.

[0258] For approach 1, one method to define the channel correlation accuracy is to compare the correlation value of each TRS pair channel measurement with the Genie channel correlation value.

[0259] Instantaneous TDCP accuracy = instantaneous channel correlation value of the measurement channel - instantaneous channel correlation value of the Genie channel.

[0260] However, for the terminal, which TRS pair will be used for calculation depends on the terminal implementation. The industry has not yet reached a consensus on which TRS to use to generate the measurement results of the TDCP report. As shown in Figure 1B, for the time slot with a delay value of D=1, two different pairs of TRS resources can be used. The correlation values ​​measured by the two TRS pairs may be different. The delay value is also the arbitrary time interval between the two TRSs in the aforementioned TRS pair. In addition, the terminal can even average the results. Figure 1B is just an example of TRS pair selection. The user equipment (UE) can select TRS pairs based on different channel state information-reference signal (CSI-RS) resource sets, or select different TRS pairs at different times. Since the testing equipment (TET) does not know which TRS pair the UE will use or whether the UE performs averaging, it is difficult for the TE to determine the Gini correlation value corresponding to the measured correlation value reported by the UE. For different TRS pairs, the Genie channel correlation value may not match the measured channel correlation value. The UE here can be equivalent to the aforementioned first device. The TE here can be equivalent to the aforementioned second device.

[0261] Therefore, a mechanism needs to be designed to ensure that both the UE and TE know which TRS pair to use or whether to use averaging for calculation. Since TDCP is aperiodic reporting, the terminal may choose to report the latest TRS pair before the configured uplink resource.

[0262] As shown in Figure 5, assume that the possible uplink (UL) resource is located at T1. The UE will then select {TRS3, TRS1} to calculate the measured channel correlation value, and the one that is closest to the UL resource TDCP will be reported. From the TE's perspective, the TE will also select the Genie channel correlation value (also known as the Genie value) corresponding to the TRS pair {TRS1, TRS3}. The UE can also take the average of the last two or more TRS pairs for calculation. Regardless of whether the time domain averaging of the correlation values ​​is used, the UE and TE will follow the rules. In short, before reporting the UL resource, the UE will select the most recent one or more TRS pairs for calculation. The TE will determine the accuracy based on this. Taking Figure 1B as an example, assume D = 1 time slot. The TE can know the ideal channel coefficients corresponding to each TRS and then calculate the instantaneous channel correlation value using a TRS pair, such as the correlation value between (TRS0, TRS2) or (TRS1, TRS3). Due to the fading characteristics of the fading channel, the correlation value between (TRS0, TRS2) and (TRS1, TRS3) may be different depending on Doppler propagation.

[0263] After the UE determines the TRS pair to be calculated, the channel correlation value can be calculated as follows:

[0264] The wideband normalized channel time measured by TDCP can be defined as:

[0265] Where Dn is the interval between two TRS symbols in the time domain, and N is the number of subcarriers.

[0266] Finally, the UE reports the instantaneous estimated correlation value to the TE. The TE compares the difference between the instantaneous estimated correlation and the instantaneous Genie value. This test is repeated multiple times. If these differences are less than a 90% threshold, the UE passes the accuracy test.

[0267] Method 1 may include the following two optional embodiments:

[0268] Optional implementation method 1:

[0269] If time domain averaging of the correlation values ​​is not performed, the following operations may be included:

[0270] 1. The UE is configured to make multiple irregular TDCP reports. The time offset between two TRSs will be provided in the configuration, for example, there may be several candidate TRS pairs for calculation.

[0271] 2. The UE shall perform TDCP reporting on the latest TRS pair before selecting UL resources to calculate the instantaneous correlation of the channel.

[0272] 3. The UE will report the real-time estimated channel-related results to the TE multiple times.

[0273] 4. TE determines the channel Genie channel correlation value based on the latest TRS pair before the UL resource for TDCP reporting.

[0274] 5. TE compares the difference between the instantaneous estimated channel correlation value and the Genie channel correlation value. If the difference is less than the 90% threshold, the UE will pass the test.

[0275] Optional implementation method 2:

[0276] If time-domain averaging of the correlation values ​​is performed, the following operations may be included:

[0277] 1. The UE is configured to make multiple irregular TDCP reports. The time offset between the two TRSs in a TRS pair will be provided in the configuration. For example, there may be several candidate TRS pairs for calculation.

[0278] 2. The UE selects the latest m (m>1) TRS pairs before UL resources for TDCP reporting and calculates the instantaneous channel correlation value by time averaging.

[0279] 3. The UE reports the instantaneous average estimated channel correlation results to the TE multiple times.

[0280] 4. TE determines the Genie average channel correlation value by time averaging based on the latest m TRS pairs before the UL resource for TDCP reporting.

[0281] 5. TE compares the difference between the instantaneous average estimated channel correlation value and the Genie average channel correlation value. If the difference is less than the 90% threshold, the UE will pass the test.

[0282] Mode 1 may include the following optional embodiments:

[0283] For a typical U-shaped Doppler spread spectrum, the theoretical time correlation value is the Bessel function. Depending on the D, different Genie correlation values ​​can be obtained as the baseline.

[0284] 1. The UE is configured to make multiple, irregular TDCP reports. It provides the time offset between two TRSs, such as DY. For each report, the UE quantizes the estimated channel instantaneous correlation value and reports the result to the TE.

[0285] 2. TE will collect TDCP reports multiple times and calculate the average channel correlation value.

[0286] 3.TE obtains the Genie channel correlation value from the Bessel function. For each different DY, the Genie correlation value is different.

[0287] 4. The TE compares the average correlation value with the correlation value of the Genie channel derived from the Bessel function. If the difference is less than the threshold, the UE passes the test.

[0288] TDCP difference = correlation value of the measurement channel - correlation value of the Genie channel (derived from the Bessel function).

[0289] The accuracy of TDCP is tested through additive Gaussian (AWGN channel). The accuracy of TDCP can also be tested through AWGN channel. For AWGN channel, the channel Genie channel correlation value is always 1. This test method can be based on the difference in channel instantaneous correlation value. The UE will estimate the channel instantaneous correlation through TRS pair and report it to TE. However, the UE does not need to select which TRS pair to use for calculation. For the TE side, the channel Genie channel value is always 1. TE does not need to determine the Genie value based on the TRS pair. The TE can then calculate the difference between the UE estimated correlation value and 1.

[0290] 1. The UE is configured to make multiple irregular TDCP reports. The time offset between two TRSs will be provided in the configuration. For example, there may be several candidate TRS pairs for calculation. An AWGN channel is assumed for testing.

[0291] 2. The UE may select m (m=>1) pairs of TRSs to calculate the instantaneous channel correlation. If m>1, time averaging will be applied.

[0292] 3. The UE will report the real-time estimated channel-related results to the TE multiple times.

[0293] 4. The TE compares the difference between the instantaneous average estimated channel correlation and 1 (Genie average channel correlation value). If the difference is less than a threshold of 90%, the UE passes the test.

[0294] Due to channel fading, the instantaneous channel correlation values ​​of different TRS pairs will vary. On the terminal side, the selection of which TRS pair to use for correlation value calculation depends on the terminal implementation and has not yet been agreed upon in the industry.

[0295] For example, the two TRSs shown in FIG5 can both be used to calculate correlation values, and the correlation values ​​calculated by the two TRSs may be different.
