[0032] Positioning technology calculates the position of a target node by receiving and measuring reference signals. In uplink positioning, a user equipment (UE) transmits uplink sounding reference signals (SRS), and multiple transmission and receiving points (TRPs) receive the uplink SRS and perform corresponding measurements, thereby calculating the position of the UE. In downlink positioning, a TRP transmits downlink PRS, and a UE receives the downlink PRS transmitted from multiple TRPs and performs corresponding measurements, thereby calculating the position of the UE. Perception technology calculates the attributes of a perception target by receiving and measuring reference signals. The attributes can be position, speed, type, etc. In uplink perception, a perception transmitting node transmits a perception reference signal, and a perception receiving node receives the perception reference signal and performs corresponding measurements, thereby obtaining a perception result. An AI / ML model can obtain the position of a UE by inference, thereby implementing positioning. An AI / ML model can also be applied in a perception process.

[0138] Embodiment 1

[0139] Measurement configuration and reporting:

[0140] For measurement configuration, the network can configure the UE / TRP with at least one of the following parameters: reported sample / path / measure number: Nt', the number of samples / paths / measurements that the UE / TRP can report can be between Nt' and Nt; consecutive sample / path / measure number: Nt; reported sample / path / measure rule, the rule can be configured based on the UE / TRP reported capability.

[0141] Indicate whether the UE / TRP needs to report according to the sample / path / measure rule, if the indication is 1 or true, the UE / TRP needs to report according to the rule, if the indication is 0 or false, the UE / TRP does not need to report according to the rule. The rule can be the sample / path / measure with the strongest power.

[0142] Indicate whether the UE / TRP is allowed to report the sample / path / measure with one or more differences, the indication can be configured based on the UE / TRP reported capability.

[0143] Indicate the difference of the sample / path / measure reported by the UE / TRP, the difference can be at least one of the following: absolute / relative power value (in dB / dBm or percentage / decimal), sample / path / measure number difference, sample / path / measure number absolute value, sample / path / measure number upper limit, sample / path / measure number lower limit.

[0144] For measurement reporting, the UE / TRP reports at least one of the following parameters to the network: reported sample / path / measure number: Nt'; indicate whether the reported sample / path / measure number is according to the network's configuration, if the indication is 1 or true, it means that the UE / TRP reports according to the network's configuration, if the indication is 0 or false, it means that the UE / TRP does not report according to the network's configuration. If the indication is 0 or false, the difference between the number of samples / paths / measurements that the UE / TRP can report and the configured number, the difference can be positive / negative, where positive means the number of samples / paths / measurements reported is greater than the configured number, and negative means the number of samples / paths / measurements reported is less than the configured number.

[0145] Number of samples / paths / measurements: Nt; whether to support the reporting rule of samples / paths / measurements; indication [whether] / [whether capable] to report according to the rule of samples / paths / measurements, if indicated as 1 or true, it means that the UE / TRP reports the samples / paths / measurements according to the rule, if indicated as 0 or false, it means that the UE / TRP does not report the samples / paths / measurements according to the rule. The rule can be the strongest sample / path / measurement; supported sample / path / measurement rule, wherein the rule can be the strongest sample / path / measurement, and / or the reporting of samples / paths / measurements according to the power threshold, and / or the reporting of the maximum power sample / path / measurement, etc.; indication [whether] / [whether capable] to report the sample / path / measurement with one or more differentials; supported / reported one or more differential values, wherein the differential can be at least one of the following: absolute / relative power value (in dB / dBm, or percentage / decimal), sample / path / measurement number difference, sample / path / measurement number absolute value, sample / path / measurement number upper limit, sample / path / measurement number lower limit.

[0146] Example of differential configuration:

[0147] For example, the UE reports to the network that it is capable of reporting with one or more differentials, and the supported differential value is 32, the network configures the UE with an indication that allows the UE / TRP to report with differentials, and configures Nt' = 64, wherein the configuration of the differential ΔNt' = 32, then the range of the number of samples / paths / measurements reported by the UE / TRP is [Nt'- ΔNt', Nt'+ ΔNt'], that is, the UE / TRP can report 32-96 samples / paths / measurements.

[0148] If the configuration of the differential is 1 dB, it means that the sample reported by the UE / TRP can have a differential range of 1 dB, that is, the non-strongest sample / path / measurement can also be reported, but it needs to be within 1 dB of the interpolation of the strongest sample / path / measurement.

[0149] Example of reporting rule:

[0150] For example, the network configures the UE / TRP with an indication of 1, that is, it indicates that the UE / TRP needs to report according to the rule of samples / paths / measurements, but the UE / TRP does not report according to the configured rule in actual reporting, then the UE / TRP will report an indication of 0 when reporting, that is, it indicates that it does not report according to the configured rule.

[0151] Example of reporting number:

[0152] For example, the network configures the UE / TRP to report Nt’=64 samples / paths / measurements, and the UE / TRP reports Nt’=128 samples / paths / measurements, the UE / TRP reports 0 to the network, and the difference between the reported number and the configured number is 64; if the UE / TRP reports 32 samples / paths / measurements, the UE / TRP reports 0 to the network, and the difference between the reported number and the configured number is -32.

[0153] Through the above method, the UE / TRP can report samples / paths / measurements within a certain range, while ensuring a certain generalization performance and specifying the reporting range.

[0154] Embodiment 2

[0155] Measurement reporting grid rules:

[0156] In general, the UE / TRP will select Nt’ samples / paths / measurements from the continuous Nt samples / paths / measurements for reporting, where the selection of samples / paths / measurements has a certain time granularity, i.e., the time interval between adjacent two samples / paths / measurements is a fixed value. FIG. 3 provides an example diagram of a time interval.

[0157] The time information reported by the UE / TRP is the time difference of the sample / path / measurements time compared to the reference / starting time, where the reported time interval / time granularity is denoted by k, which means the time interval is 2^k*Tc, where Tc is a unit time in the communication system, and the specific calculation method is: T c = 1 / (Δf max ·N f ), where Δf max = 480·10 3 Hz, N f = 4096. For example, when k = 1, T = 2^1*Tc, and the reported time is 100, which means the time difference of the sample / path / measurements time compared to the reference / starting time is 100*2*Tc.

[0158] The network can configure the UE / TRP with the start / starting position / starting point of the continuous samples / paths / measurements, where the starting point also needs to be expressed in a given time interval / time granularity. That is, the configuration of the start / starting position / starting point includes the time granularity / time interval k and the time difference of the start time compared to the reference / starting time. The end / ending position / ending point of the continuous samples / paths / measurements can also be configured in the same way.

[0159] Figure 4 provides a schematic diagram of the relationship between position and time interval. As shown in Figure 4, when k = 2, the time granularity / time interval is T = 2^2*Tc, the starting position is 8, the time difference between the starting time and the starting / reference time is 8*T = 32Tc, and the ending position is 17, the time difference between the ending time and the starting / reference time is 17*T = 68Tc.

[0160] The reference time reported by the UE / TRP measurement can include a system frame number (SFN) and a subframe number, which can be the time when the UE transmits the SRS for uplink measurement. The starting point can be used to divide the sample / path / measurement reporting grid with granularity T. When the UE / TRP detects the positioning reference signal, it will be processed, i.e. inverse fast Fourier transform (IFFT) or inverse discrete Fourier transform (IDFT) operation within the fast Fourier transform (FFT) or discrete Fourier transform (DFT) window, the starting point of FFT / DFT can be the time when the UE / TRP receives the positioning reference signal. The time interval between adjacent samples / paths / measurement points in this (FFT / DFT) window is also expressed in the given time interval / time granularity. In some cases, the sample / path / measurement points within the FFT / DFT window are aligned / overlap with the sample / path / measurement reporting grid points divided by the starting / reference time, in which case the UE / TRP can directly obtain the sample / path / measurement result after sampling / time-frequency domain transformation; in some cases, the sample / path / measurement points within the FFT / DFT window are not aligned / overlap with the sample / path / measurement reporting grid points divided by the starting / reference time, in which case the UE / TRP can obtain the sample / path / measurement result by implementation / processing, wherein the processing method can include hardware processing of the UE / TRP, such as fitting / oversampling to obtain the result at the sample / path / measurement reporting grid point. Figure 5 provides a schematic diagram of the FFT window changing over time.

[0161] By the above method, the sample / path / measurement reporting of the UE / TRP will be limited to the given grid, reducing the complexity of data preprocessing.

[0162] Embodiment 3

[0163] Timestamp of measurement reporting:

[0164] Generally, in measurement reporting, the network requests the UE / TRP to perform the measurement and the UE / TRP reports the measurement within one 1024 SFN. FIG. 6 provides an illustration of measurement request and measurement reporting. The black rectangular box in the figure represents the measurement. As shown in FIG. 6, the time span of measurement request and reporting should not exceed 1024 SFN.

[0165] For AI / ML data collection, the network requests the UE / TRP to perform the measurement, and the UE / TRP can perform the measurement at different time. Multiple measurements can span multiple 1024 SFN, and multiple measurement results can be reported at the same time. FIG. 7 provides another illustration of measurement request and measurement reporting. The black rectangular box in the figure represents the measurement. As shown in FIG. 7, the measurement reporting can span multiple 1024 SFN.

[0166] If the measurement timestamp in the measurement reporting of the UE / TRP only includes SFN / slot number / orthogonal frequency division multiplexing (OFDM) index, the network cannot obtain the specific time of different measurement execution. Therefore, a superframe indication / superframe number can be included in the timestamp of the UE measurement reporting to indicate the measurement performed in the measurement of the superframe. The network configures the measurement request to configure the superframe range and / or the start time of the superframe and / or the end time of the superframe of the measurement, wherein the superframe range can be an integer value (0-1023), the start time can be the time of SFN0 in the first superframe, and the end time can be the time of SFN0 of the end superframe. The start / end time and / or superframe range can be configured according to the capability of the UE / TRP. FIG. 8 provides an illustration of the time corresponding to the measurement execution.

[0167] FIG. 9 provides an illustration of the start absolute time of the measurement execution, wherein the start absolute time can refer to the time corresponding to the SFN0 of the superframe of the measurement execution / starting corresponding time / SFN initialization time.

[0168] The timestamp reported by the UE / TRP in the measurement report can include absolute time, which can be coordinated universal time (UTC time), or time relative to a common reference time. The absolute time can be the time when the measurement is performed, or the time corresponding to SFN0 of the superframe in which the measurement is performed. The network configures the start absolute time and / or end absolute time of the measurement and / or the time length of the measurement request when configuring the measurement request. The start time / end time / time length can be expressed in years / months / days / hours / minutes / seconds / milliseconds. The start / end time and / or time length can be configured according to the capability of the UE / TRP. The network can also configure the number of measurements, indicating that multiple measurements can be included in one report. The measurement report of the UE / TRP can include one or more timestamps, each corresponding to the time of one measurement.

[0169] If the timestamp does not include absolute time / SFN initialization time, the network can assume that the nodes of the measurement have the same SFN initialization time as the network.

[0170] The UE / TRP reports the following capabilities for indicating the reporting of multiple measurements: indicating whether it has the capability to include multiple measurements in one report, 1 or true indicating the capability to report multiple measurements, and 0 or false indicating no capability to report multiple measurements; indicating the number of measurements supported in one report; indicating the time length that can be covered in one report, which can include at least one of the following: number of superframes, number of SFNs, number of slots, number of OFDM symbols, length of years / months / days / hours / minutes / seconds / milliseconds.

[0171] The above capabilities are limited by the storage, processing and computing capabilities of the UE / TRP.

[0172] Examples of reporting:

[0173] For example, the UE / TRP reports an indication of 1, indicating the capability to include multiple measurements in one report, reports an indication of the number of measurements supported in one report as N=128, and reports an indication of the length that can be covered in one report as T=10 superframes, which means that the UE can complete and store 128 measurement results in 10 superframes. The network can configure according to the reported capability information of the UE / TRP, such as configuring one report to include N'=64 measurements (N'< = N). After receiving the configuration, the UE / TRP performs measurement reporting. The actual measurement report can include 64 measurements (or more or less than 64 measurements), and each measurement can have a corresponding timestamp.

[0174] Through the above method, the UE / TRP / network can send / receive multiple measurement results in one measurement report, effectively reducing the number of communications between different network nodes.

[0175] Embodiment 4

[0176] Pairing of measurements and positions:

[0177] In AI / ML positioning procedure, the dataset for model training, monitoring usually contains two parts:

[0178] 1. Measurement information of positioning reference signals.

[0179] For uplink positioning, the measurement information includes the measurement results of sounding reference signals (SRS) transmitted by multiple TRPs for the same UE, denoted as U1, U2, …, UN, representing the measurement results of TRP1, TRP2, …, TRPN for the UE, each measurement result is associated with a timestamp; for downlink positioning, the measurement information includes the measurement results of positioning reference signals (PRS) transmitted by multiple TRPs for the same UE, denoted as D1, D2, …, DN, representing the measurement results of PRS transmitted by TRP1, TRP2, …, TRPN for the UE, each measurement result is associated with a timestamp;

[0180] 2. Position information of the UE, the position information is associated with a timestamp.

[0181] From the above information, it can be found that one UE position corresponds to N measurement results, and it is necessary to match one UE position with N measurement results. To achieve the above matching, the network can configure or the UE / TRP reports the time range / time span / time difference value of the measurement, and the measurements within a given time can form a group of measurement information. The time range can be a time difference / time span / time range compared to the UE position timestamp. The timestamp of uplink measurement corresponds to the time when the UE transmits SRS or the time when the TRP measures SRS, and the timestamp of downlink measurement corresponds to the time when the UE measures PRS or the time when the TRP transmits PRS. The specific form of the timestamp can refer to embodiment 3.

[0182] For example, if the UE position timestamp is T1 and the configured / reporting time range is ΔT, then the measurement results within T1-ΔT to T1 can be matched with the UE position. The measurement results centered at T1, i.e. the measurement results within T1-ΔT / 2 to T1+ΔT / 2 can be matched with the UE position; the network can configure or the UE reports that a group of measurements can contain the number of corresponding measurement results of TRPs. Multiple measurement results can be associated with a timestamp, which can be the timestamp corresponding to the earliest / latest time, or the timestamp corresponding to the middle time of the earliest / latest time, or the timestamp corresponding to any time within the earliest / latest time range.

[0183] For example, if the UE location timestamp is T1 and the number of configured / reported measurement results is N, then N measurement results before T1 can be matched with the UE location. When N is even, N / 2 measurement results before T1 and N / 2 measurement results after T1 can be matched with the UE location; when N is odd, N / 2 or N / 2+1 measurement results before T1 and N / 2 or N / 2+1 measurement results after T1 can be matched with the UE location.

[0184] If the network / UE has one UE location information and corresponding timestamp and multiple measurement information and corresponding multiple timestamps, the network / UE selects one or more measurement information corresponding to the latest UE location information timestamp to form a set of training data / samples.

[0185] FIG. 10 provides a schematic diagram of measurement results at different times. As shown in FIG. 10, the network / UE derives the UE location corresponding to the time of UE location #1, i.e., the network / UE calculates the UE location #1 at a certain time to obtain the UE location, but the UE has N+2 measurement results before this time, and the network / UE needs to select measurement information matching the UE location from multiple measurement results to form a set of training data / samples. N measurement results closest to the time of calculating UE location #1 can be selected, or measurement results within a certain time range / time span from the time of calculating UE location #1 can be selected.

[0186] FIG. 11 provides a schematic diagram of matching of multiple sets of training data samples, wherein the timestamp of calculating the UE location can also be at the middle position of multiple measurement times.

[0187] FIG. 12 provides a schematic diagram of UE measurement for downlink positioning. For downlink positioning, the above-mentioned multiple measurements come from the measurement of PRS sent by different TRPs by the same UE.

[0188] FIG. 13 provides a schematic diagram of TRP measurement for uplink positioning. For uplink positioning, the above-mentioned multiple measurements can come from one or more different TRPs.

[0189] FIG. 14 provides a schematic diagram of measurement combining uplink positioning and downlink positioning. For positioning combining uplink and downlink, the above-mentioned multiple measurements can come from one UE and one or more TRPs.

[0190] Through the above method, the UE / TRP / network can match different measurements and label information when performing model training and model monitoring to complete the AI / ML positioning function.

[0191] Embodiment 5

[0192] Training inference consistency:

[0193] In AI / ML, to guarantee the training performance, the model needs to maintain the same / similar features of the data used in training and inference. For positioning, for example, the data is collected indoors in the training data collection phase, while the positioning is performed in the outdoor scenario in the model inference phase, there is a certain difference in the data features, which may worsen the model inference performance.

[0194] For positioning, in addition to the configuration of the positioning reference signal, the factors that determine the measurement features also include the antenna characteristics of the sending node, the antenna array dimension, the horizontal / vertical antenna element spacing, the array configuration, the antenna radiation direction characteristics, the beamforming configuration and / or implementation, etc. However, this part of the feature may involve the privacy / security issue of the sending node, which cannot be provided to the measurement node explicitly.

[0195] The UE / TRP can send the sending / receiving / correlation (implementation / transmission / reception method) index of the reference signal / node to the network or the network to the TRP / UE, indicating the following at least one property of the sending node in sending the positioning reference signal: antenna characteristics, antenna height, antenna array dimension, horizontal / vertical antenna element spacing, array configuration, antenna radiation direction characteristics, beamforming configuration and / or implementation.

[0196] This sending and / or receiving index can be associated with at least one of the following: a UE / TRP ID, or a reference signal resource / resource set, or a model ID.

[0197] If the sending / receiving index values of two or more positioning reference signals are the same, it indicates that the device receiving / sending of the two or more positioning reference signal measurements uses the same sending / receiving method. If the device has used the same sending / receiving index for the sending / receiving of the positioning reference signal, this field is mandatory; otherwise this field can not exist.

[0198] The UE / TRP can send the sending / receiving (implementation / transmission / reception method) change indication of the reference signal to the network or the TRP / UE, 1 indicating that the sending / receiving characteristics have changed, and 0 indicating that the sending / receiving characteristics remain unchanged. When the sending and / or receiving characteristic change indication is 0, it indicates that the corresponding measurement can be applied to the same model / the same application.

[0199] FIG. 15 provides a diagram of the relationship between a model and a transmission index. For example, for downlink positioning, as shown in FIG. 15, the transmission index of a TRP is 3 when transmitting downlink positioning reference signal resource set 1, 3, and is 4 when transmitting downlink positioning reference signal resource set 2, 4. If the model is at the UE side, the UE will use different model training data collection and model inference when receiving different resource sets. If the model is at the network side, the network will use different model training and model inference when receiving measurement results of different positioning reference signals. Similarly, for uplink positioning, the transmission index of an uplink reference signal can also be associated with different models.

[0200] More specifically, for downlink positioning, a UE can report a reception index to the network, and a TRP can report a transmission index to the network; for uplink positioning, a UE can report a transmission index to the network, and a TRP can report a reception index to the network. The reception / transmission index is associated with a specific model / resource / resource set / TRP ID / UE ID / model ID. When the transmission index and the reception index corresponding to certain measurements are the same, these measurements can be used for training and inference of the same model. For example, for downlink positioning, for one transmission / reception mode of resource set 2, the reception index used by the UE is 1, and the transmission index used by the TRP is 3. This transmission / reception mode corresponds to model 1. For another transmission / reception mode of resource set 2, the reception index used by the UE is 1, and the transmission index used by the TRP is 2. This transmission / reception mode corresponds to model 2. FIG. 16 provides a diagram of the relationship between a model and a transmission index and a reception index.

[0201] The network can configure one or more margin values for a UE / TRP, where the one or more margin values respectively represent the margin of the following transmission / reception characteristics: the margin of the transmission and / or reception antenna height, which can be in units of meters, centimeters, millimeters, etc.; the margin of the transmission and / or reception antenna array dimension, which can be an integer value; the margin of the transmission and / or reception horizontal / vertical antenna element spacing, which can be in units of centimeters, millimeters, nanometers, etc.; the margin of the transmission and / or reception antenna radiation direction, which can be in units of angle; the margin of the transmission and / or reception timing error group, which can be in units of time (such as Tc) or the number of groups; the margin of the transmission and / or reception phase error group, which can be in units of angle or the number of groups.

[0202] The transmission / reception index within a certain margin range can be the same.

[0203] For example, the network configures a difference value of receiving antenna height Xm, the index of the first transmission of the positioning reference signal is 1, and the antenna height at this time is 25m. If the antenna height H satisfies 25-X <= H <= 25+X at the second transmission of the positioning reference signal, the index of the second transmission of the positioning reference signal can also be 1.

[0204] The network can configure one or more difference values (margin values) of the transmission / reception index for the UE / TRP. The transmission / reception index within a certain difference value range can be used for the same model or for the same application or for the same type of application.

[0205] For example, the network configures a difference value of the transmission index Isd=2, and the index of the first transmission of the positioning reference signal is Is1=5. If the transmission index Is satisfies Is1-Isd <= Is <= Is1+Isd at the second transmission of the positioning reference signal, it is considered that it can be used for the same model / same application / same type of application, that is, the transmission characteristics with the transmission index range in [3, 7] can be used for the same model / same application / same type of application.

[0206] For example, the network configures a difference value of the transmission index Isd=2, and the index of the first transmission of the positioning reference signal is Is1=5. If the transmission index Is satisfies Is1-Isd <= Is <= Is1+Isd at the second transmission of the positioning reference signal, it is considered that it can be used for the same model / same application / same type of application, that is, the transmission characteristics with the transmission index range in [3, 7] can be used for the same model / same application / same type of application.

[0207] The UE / TRP can report its sending / receiving capability to the network, wherein the capability can include one or more of the following capability indication / capability range: antenna characteristic index indication, indicating whether the node is capable of indicating the antenna characteristic; antenna characteristic index range indication, indicating the supported index range; antenna array dimension indication, indicating whether the node is capable of indicating the antenna array dimension; antenna array dimension range indication, indicating the supported dimension range; horizontal / vertical antenna element spacing indication, indicating whether the node is capable of indicating the antenna element spacing; horizontal / vertical antenna element spacing range indication, indicating the supported dimension range; array configuration index indication, indicating whether the node is capable of indicating the array configuration; array configuration index range indication, indicating the supported index range; antenna radiation direction characteristic index indication, indicating whether the node is capable of indicating the antenna radiation direction characteristic; antenna radiation direction characteristic index range indication, indicating the supported index range; beamforming index configuration indication, indicating whether the node is capable of indicating the beamforming configuration; beamforming index configuration range indication, indicating the supported index range; beamforming implementation indication, indicating whether the node is capable of indicating the beamforming implementation; beamforming implementation range indication, indicating the supported index range; antenna height indication, indicating whether the node is capable of indicating the antenna height; antenna height range indication, indicating the supported height range; synchronization error indication, indicating whether the node is capable of indicating the supported synchronization error; synchronization error range indication, indicating the supported synchronization error range.

[0208] The above capability can be associated with different model IDs or different applications.

[0209] For uplink positioning, the feasible signaling procedure is as follows: 1. The UE reports the sending index capability to the network, and / or the TRP reports the receiving index capability to the network; 2. The network configures the difference value of different sending indexes or the difference value of sending characteristics for the UE, and this configuration can be based on the capability reported by the UE; 3. The UE reports the sending index to the network; 4. The network carries the sending index information of the UE when sending the positioning reference signal configuration to the TRP.

[0210] For downlink positioning, the feasible signaling procedure is as follows: 1. The TRP reports the sending index capability to the network, and / or the UE reports the receiving index capability to the network; 2. The network configures the difference value of different sending indexes or the difference value of sending characteristics for the TRP, and this configuration can be based on the capability reported by the TRP; 3. The TRP reports the sending index to the network; 4. The network carries the sending index information of the TRP when sending the positioning reference signal configuration to the UE.

[0211] For the positioning mode of uplink and downlink combination, the feasible signaling procedure is as follows: 1. The TRP / UE reports the capability of sending / receiving index to the network; 2. The network configures the difference value of different sending / receiving indexes for the TRP / UE, which can be configured based on the capability reported by the TRP / UE; 3. The TRP / UE reports the sending / receiving index to the network; 4. The network carries the sending / receiving index information of the TRP / UE when sending the positioning reference signal configuration to the TRP / UE.

[0212] The above signaling procedure part can be omitted.

[0213] The above method can effectively ensure the consistency of the AI / ML model during training and inference, and the same model uses the same or similar data set / data during training and inference, effectively improving the performance of the AI / ML model.

[0214] Embodiment 6

[0215] Reference signal received power (RSRP) / reference signal received path power (RSRPP) / reference signal sample received power reporting parameters, wherein the reference signal sample received power reporting parameters can be the received power of each sample. In some embodiments, the parameters can be the granularity.

[0216] In the protocol, the reporting range of the positioning reference signal RSRP / RSRPP measurement is defined as-156dBm to-31dBm, with a resolution of 1dB, represented by an integer 0-126, that is, 0 represents RSRP / RSRPP<-156dBm, 1 represents-156dBm<=RSRP / RSRPP<-155dBm, 2 represents-155dBm<=RSRP / RSRPP<-154dBm, and so on, and 126 represents-31dBm<=RSRP / RSRPP.

[0217] For differential reporting, the differential RSRP / RSRPP / reference signal sample received power is reported as the difference from the first reported RSRP / RSRPP / reference signal sample received power, with a unit of dB.

[0218] The network can request the UE / TRP to report the supported RSRP / RSRPP / received power granularity of the sample of reference signal or parameters, and the UE / TRP can report the supported RSRP / RSRPP / received power granularity of the sample of reference signal to the network. In the measurement reporting request, the network can request the UE / TRP to report at a given RSRP / RSRPP / received power granularity of the sample of reference signal, and the measurement reporting request can request the UE / TRP to report the supported RSRP / RSRPP / received power granularity of the sample of reference signal.

[0219] The RSRP / RSRPP / received power granularity of the sample of reference signal can be represented as follows: the value range x of the RSRP / RSRPP / received power of the sample of reference signal can be 1, 2, …, X, representing 1dB, 1 / 2^1dB, 1dB, 1 / 2^2dB, …, 1 / 2^XdB, respectively. In the above value range, 1 represents 1dB, 2 represents 1 / 2dB, and 1 / x dB.

[0220] Different RSRP / RSRPP / received power granularities of the sample of reference signal correspond to different reporting values. For example, when the reporting granularity is 1, the reporting value is represented by an integer from 0 to 126; when the reporting granularity is 2, the reporting value is represented by an integer from -126 to 126 or 0 to 252; and so on. When reporting the RSRP / RSRPP / received power measurement result of the sample of reference signal, the UE / TRP can report one or more measurement values, one of which is the measurement information with 1dB resolution, and the other is the measurement information with finer granularity. The mapping relationship between the first reporting value and the RSRP / RSRPP / received power measurement value of the sample of reference signal is as follows: 0 represents RSRP / RSRPP / received power of the sample of reference signal <-156dBm, 1 represents -156dBm<=RSRP / RSRPP / received power of the sample of reference signal <-155dBm, 2 represents -155dBm<=RSRP / RSRPP / received power of the sample of reference signal <-154dBm, and so on, and 126 represents -31dBm<=RSRP / RSRPP / received power of the sample of reference signal. The mapping relationship between the second reporting value and the RSRP / RSRPP / received power value of the sample of reference signal is as follows: when the granularity is 1 / 2dB, 0 represents the first 1 / 2dB in the 1dB range, and 1 represents the last 1 / 2dB in the 1dB range; when the granularity is 1 / 4dB, 0, 1, 2, and 3 represent different parts in the 1dB range, respectively.

[0221] For example, the first reported value is 12, the corresponding RSRP / RSRPP / received power range of the sample of reference signal is between -145 and -144, the granularity of the second reported value is 1 / 4 dB, and the reported value is 2, so the range of RSRP / RSRPP is between -144.75 and -144.5 dBm.

[0222] The UE / TRP capability, configuration, and reporting described above are also applicable to the differential of the received power of the sample of RSRP / RSRPP / reference signal. The differential of the received power of the sample of RSRP / RSRPP / reference signal is reported as the dB difference relative to the first report or the received power of the sample of RSRP / RSRPP / reference signal of a certain reported value. The differential value range of the received power of the sample of RSRP / RSRPP / reference signal is defined as -30 dB to 0 dB, the resolution is 1 dB, and it is represented by an integer 0-30, wherein the finer granularity of the reported value and the mapping relationship can be the same as the received power of the sample of RSRP / RSRPP / reference signal described above.
