Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a speed measurement method, device, apparatus, and storage medium. Background Technology

[0002] In an Integrated Sensing and Communication (ISAC) system, sensing the velocity of an object requires a certain sensing resolution (e.g., target object velocity sensing resolution: 0.3 m / s). Without considering the signal-to-noise ratio (SNR), the accumulation duration of measurement symbols (including symbol intervals) determines the velocity sensing resolution, while the measurement symbol interval determines the maximum perceived velocity. A longer accumulation duration results in a smaller sensing resolution, a smaller measurement symbol interval, and a larger maximum perceived velocity.

[0003] To reduce resource consumption, time decimation can be used to reduce the number of measurement symbols while keeping the accumulation time constant, thus maintaining the same resolution. However, this method increases the interval between measurement symbols, thereby reducing the maximum sensing speed. Summary of the Invention

[0226] To facilitate a clearer understanding of the technical solutions of the various embodiments of this application, some technical content related to the various embodiments of this application will be introduced first.

[0227] 1. ISAC

[0228] ISAC, as a key candidate evolution technology for New Radio (NR) systems, is based on the idea of ​​introducing wireless sensing capabilities into wireless mobile communication. Wireless sensing refers to sensing environmental information via wireless signals. This information includes the distribution, size, quantity, and temperature of environmental objects, human actions and behaviors, and even human breathing rate and heart rate. The principle of wireless sensing involves transmitting radio signals to the environment at the sensing transmitter and simultaneously collecting the reflected, scattered, and multipath-transmitted wireless signals at the sensing receiver. Because the collected wireless signals are influenced by the environment, they carry environmental information. After receiving the signals and undergoing complex signal processing, environmental characteristics can be discovered, and the sensed environment can be reconstructed on a computer. This includes identifying people and objects in the environment, detecting temperature, detecting human movements, and even monitoring breathing and heart rate. It can be used in fields such as health monitoring and security.

[0229] Wireless sensing is generally divided into two modes: mono-static sensing and bi-static sensing. Mono-static sensing refers to a base station (or terminal) actively transmitting a sensing signal, which is then reflected by the object being sensed and received by the same base station (or terminal). Bi-static sensing refers to a base station (or terminal) transmitting a sensing signal, which is then transmitted through a wireless channel and received by another base station (or terminal).

Dual-base sensing includes: UE-gNB dual-base sensing, gNB-UE dual-base sensing, UE-UE dual-base sensing, and gNB-gNB dual-base sensing.

[0236] The range of perceived speed is typically from 0 to ±v. max Theoretically, the maximum perceived speed v max for:

[0237]

[0238] Where N t This measures the number of symbols used in the signal, with symbols transmitted at equal intervals.

[0239]

[0240]

[0241]

[0242] Where f c Δf is the carrier frequency, c0 is the speed of light, and Δf is the subcarrier spacing.

[0243] Examples are given below:

[0244] Case 1: Sensing range v is 0 to ±70 km / h, Δf = 120 kHz, speed resolution is 0.3 m / s, f c =28GHz, N sym =2002(143 slots * 14 symbols), assuming the sensing symbol intervals are uniformly distributed, then the number of symbols required in the time domain is:

[0245]

[0246] The number of sensing symbols N required in the time domain can be calculated. t There are 121.

[0247] Case 2: Sensing range v is 0 to 70 km / h, Δf = 120 kHz, speed resolution is 0.3 m / s, f c =28GHz, N sym =2002, assuming the sensing symbol interval is uniformly distributed, then the number of symbols required in the time domain is:

[0248]

[0251] Step 200: Preprocess the received signal based on the offset value or range of velocity-type measurements, where velocity-type measurements are velocity or Doppler frequency offset.

[0252] Specifically, a sensing receiver refers to a sensing node that receives sensing signals, such as a terminal or base station. For single-base sensing, the sensing receiver and the sensing transmitter are the same sensing node; for dual-base sensing, the sensing receiver and the sensing transmitter are different sensing nodes. The sensing transmitter is the sensing node that sends sensing signals.

[0253] The sensed signal refers to the sensed signal received by the sensed receiver.

[0254] After receiving the sensing signal, the sensing receiver first preprocesses the signal based on the offset value or range of velocity-type measurements. The specific form of the preprocessing is not limited in this application. In some embodiments, the sensing signal may be multiplied by a formula (function or expression), which is constructed based on the offset value or range of velocity-type measurements.

[0255] The offset or range of velocity-related measurements can be configured by the sensing function entity (or sensing server, SF), determined by the sensing receiver itself, or obtained in other ways; there are no restrictions here.

[0256] In some embodiments, preprocessing the sensed and received signal based on the velocity offset value may involve multiplying the sensed and received signal by... Where v L The offset value represents the velocity, and μ represents the time index of the signal sequence, μ = 0, ..., N′. t -1, N′ t Based on the maximum perceived speed v′ max The number of symbols required in the time domain, v′, is calculated. max Based on v L The adjusted maximum perceived speed.

[0257] Since velocity and Doppler frequency offset can be converted, all descriptions of velocity in this application are equally applicable to Doppler frequency offset, and can be modified or varied accordingly based on the conversion relationship between velocity and Doppler frequency offset. The following explanation will mainly focus on velocity, and will not elaborate on Doppler frequency offset.

[0258] It should be noted that all velocities in this application refer to radial velocities, and the line connecting the sensing receiver and the sensing target is radial.

[0259] In some embodiments, preprocessing of the sensed received signal based on the offset value or range of velocity-type measurements includes:

[0260] The first velocity or the first Doppler frequency offset is determined based on the range of velocity-type measurements.

[0261] The received signal is preprocessed based on the first velocity or the first Doppler frequency offset.

[0262] Specifically, preprocessing the received signal based on the range of speed-related measurements can involve first determining a first speed or a first Doppler frequency offset based on the range of speed-related measurements, and then preprocessing the received signal based on this first speed or first Doppler frequency offset. The specific first speed or first Doppler frequency offset is not limited; it can be a certain speed value or a certain Doppler frequency offset value determined based on the range of speed-related measurements. For example, if the speed range is 0–70 km / h, the first speed determined based on this speed range could be half of the maximum speed, i.e., 35 km / h.

[0263] This application does not limit the specific form of preprocessing the sensed and received signal based on the first velocity or the first Doppler frequency offset. In some embodiments, the preprocessing of the sensed and received signal based on the velocity offset value described above can be similar, by multiplying the sensed and received signal by a term (function or expression) constructed based on the first velocity or the first Doppler frequency offset. For example, multiplying the sensed and received signal by... Where v1 represents the first velocity.

[0264] Step 201: Determine the measured values ​​of velocity-related quantities based on the preprocessed sensing and receiving signals.

[0265] Specifically, after the sensing receiver preprocesses the sensing and receiving signal, the sensing receiver can calculate the measured value of velocity-type measurement quantities based on the preprocessed sensing and receiving signal. The specific calculation method can refer to the existing technical solution, and the preprocessed sensing and receiving signal replaces the sensing and receiving signal in the existing technical solution.

[0266] The actual velocity or Doppler frequency offset of the sensed target can be determined based on the measured value and offset value (or the first velocity and the first Doppler frequency offset) of velocity-related measurements. For example, the actual velocity of the sensed target can be obtained by adding the velocity measurement value to the velocity offset value (or the first velocity).

[0267] The following uses the Discrete Fourier Transform (DFT) speed measurement algorithm as an example to illustrate the specific implementation process.

[0268] In existing speed measurement, the sensing and receiving signal I rThe relationship between (μ) and the sensed transmitted signal I(μ) is as follows:

[0269]

[0270] The received sensing signal I r (μ), multiplied by (Taking velocity-based offset preprocessing as an example), then calculate I div (μ), here denoted as I′ div (μ), as follows:

[0271]

[0272] to I ′ div (μ) Perform DFT operation:

[0273]

[0274] The DFT result will have one or more peaks, and the DFT sequence number of the peak is used. peak The velocity measurement value v′ can be calculated:

[0275]

[0276] The actual velocity of the perceived target is v = v ′ +v L .

[0277] Since velocity and Doppler frequency deviation can be converted, if the measured value is the Doppler frequency deviation, then:

[0278]

[0279] The actual Doppler frequency offset of the perceived target is fd = fd′ + fd L , where fd L This represents the offset value of the Doppler frequency shift.

[0280] The following example illustrates the principle of the speed measurement method in this application:

[0281] Taking the previously mentioned use case 2 as an example, the sensing range v is 0 to 70 km / h, Δf = 120 kHz, and the speed resolution is 0.3 m / s. c =28GHz, N sym =2002, then the number of symbols required in the time domain is N. t for:

[0282]

[0283] The number of sensing symbols N required in the time domain can be calculated. tThere are 121.

[0284] Assuming a velocity shift occurs, the velocity offset value v L =35, then the maximum perceived speed is v′ max =v max -v L =35, then the number of symbols required in the time domain is N′ t for:

[0285]

[0286] The number of symbols N′ required in the time domain can be calculated. t There are 61.

[0287] Compared with traditional algorithms, the speed measurement method of this application saves 60 symbols required in the time domain, which is half the resources. It can be seen that, under the same symbol configuration, the speed measurement method of this application can greatly extend the maximum value of the sensing speed.

[0288] The speed measurement method provided in this application preprocesses the received signal based on the offset value or range of the speed-type measurement quantity by the sensing receiver, and then determines the measured value of the speed-type measurement quantity based on the preprocessed received signal. It can support a larger speed range under the same resolution and symbol configuration, or reduce the symbol occupation under the same resolution and speed range, so that the maximum value of the speed measurement is not limited by the time domain resource configuration (symbol interval, measurement time length), and the resource configuration can be flexibly adjusted, thereby improving the flexibility of the measurement resource configuration and reducing the waste of air interface resources.

[0289] In some embodiments, the method further includes:

[0290] Based on the measurement parameters configured by the sensing functional entity, determine the offset value or range of velocity-type measurement quantities;

[0291] The parameters related to the measurement quantity include one or more of the following:

[0292] Speed ​​range;

[0293] Doppler frequency offset range;

[0294] Velocity offset value;

[0295] Doppler frequency offset value.

[0296] Specifically, the sensing functional entity can configure one or more of the following to the sensing receiver: velocity range, Doppler frequency offset range, velocity offset value, and Doppler frequency offset value. The sensing receiver determines the offset value or range of velocity-related measurements based on the measurement-related parameters configured by the sensing functional entity.

[0297] The sensing entity can predetermine the speed (Doppler frequency offset) range according to the measurement requirements of different sensing nodes. For example, the speed (Doppler frequency offset) range of sensing node A can be set to 0 to 70 km / h (0 to 600 Hz), and the speed (Doppler frequency offset) range of sensing node B can be set to -70 to 0 km / h (-600 to 0 Hz). Then, the speed (Doppler frequency offset) range can be configured to the corresponding sensing nodes.

[0298] The sensing function entity can also configure one or more of the following parameters for the sensing transmitter: velocity range, Doppler frequency offset range, velocity offset value, and Doppler frequency offset value. Based on the measurement-related parameters configured by the sensing function entity, the sensing transmitter determines the offset value or range of velocity-related measurements. The sensing transmitter then allocates sensing resources based on the offset value or range of the velocity-related measurements and notifies the sensing receiver.

[0299] In some embodiments, the configuration methods for measurement-related parameters include:

[0300] Configure the set of parameters related to the measurement quantity through high-level parameter configuration; or,

[0301] Add configuration information for measurement-related parameters to the media access control layer signaling used to configure sensing resources.

[0302] Specifically, when a sensing entity configures measurement-related parameters to a sensing node, there are two different methods. One is to configure an optional set of measurement-related parameters through higher-level parameters, and the other is to add the configuration information of the measurement-related parameters in the Media Access Control (MAC) layer signaling used to configure sensing resources.

[0303] For example, the optional set of speed ranges {0:0~70, 1:-70~0} can be configured through the high-level parameter ISAC_speed_range.

[0304] For example, the MAC layer signaling used to configure sensing resources includes the field ISAC_speed_range{0:0~70, 1:-70~0}, which is used to configure the speed range.

[0305] In some embodiments, the measurement-related parameters are configured based on sensing nodes or sensing node groups; or, the measurement-related parameters are configured based on measurement settings.

[0306] Specifically, in some embodiments, when the sensing function entity configures measurement-related parameters to the sensing node, it can configure them based on the sensing node or sensing node group. That is, each sensing node or each sensing node group is configured with its own measurement-related parameters, and the configured measurement-related parameters are associated with the corresponding sensing node identifier or sensing node group identifier.

[0307] In some embodiments, when the sensing functional entity configures measurement-related parameters to the sensing node, it can be based on the measurement configuration, that is, the measurement-related parameters are configured separately for each measurement, and all sensing nodes in a measurement share the same configuration of measurement-related parameters.

[0308] For example, when configuring an optional set of measurement parameters through high-level parameters, the high-level parameters can be configured based on sensing nodes (groups): each sensing node (group) is configured with its own high-level parameter ISAC_speed_range{0:0~70, 1:-70~0} (ISAC_doppler_range{0:0~600, 1:-600~0}) or ISAC_speed_offset{0:35, 1:-35} (ISAC_doppler_offset{0:300, 1:-300}). This parameter is per point(s) and has a corresponding sensing node (group) identifier (Identifier, ID): ISAC_point(s)ID. Alternatively, measurement configuration can be based on high-level parameters: Configure a common high-level parameter ISAC_speed_range{0:0~70, 1:-70~0} (ISAC_doppler_range{0:0~600, 1:-600~0}) or ISAC_speed_offset{0:35, 1:-35} (ISAC_doppler_offset{0:300, 1:-300}) for all sensing nodes in each measurement. This parameter is of the common nature. Here, ISAC_speed_range represents the speed range, ISAC_doppler_range represents the Doppler frequency offset range, ISAC_speed_offset represents the speed offset, and ISAC_doppler_offset represents the Doppler frequency offset. This concept remains consistent throughout the text and will not be repeated hereafter.

[0309] For example, when adding configuration information for measurement-related parameters in the MAC layer signaling used to configure sensing resources, configuration can be based on sensing nodes (groups) through MAC layer control signaling: each sensing node (group) is instructed to include the following fields in its respective MAC layer signaling: ISAC_speed_range{0:0~70, 1:-70~0} (ISAC_doppler_range{0:0~600, 1:-600~0}) or ISAC_speed_offset{0:35, 1:-35} (ISAC_doppler_offset{0:300, 1:-300}). The signaling contains the corresponding sensing node (group) ID: ISAC_point(s)ID, which can be added to the MAC layer signaling for resource configuration. Alternatively, based on the measurement configuration, control signaling at the MAC layer can be used to indicate a common control signaling field for each measurement: ISAC_speed_range{0:0~70, 1:-70~0} (ISAC_doppler_range{0:0~600, 1:-600~0}) or ISAC_speed_offset{0:35, 1:-35} (ISAC_doppler_offset{0:300, 1:-300}). This field can be added to the MAC layer signaling in the resource configuration.

[0310] In some embodiments, the method further includes:

[0311] The system receives resource configuration information sent by the sensing transmitter. The resource configuration information is used to configure two sets of sensing resources. In the two sets of sensing resources, the first set of sensing resources is used for range estimation of velocity-type measurements, and the second set of sensing resources is used for measurement of velocity-type measurements. The first set of sensing resources is sent earlier than the second set of sensing resources.

[0312] Based on the first set of sensing resources, the range of velocity-related measurements is determined.

[0313] Specifically, the sensing transmitter can configure two sets of sensing resources for the sensing receiver. The first set of sensing resources is used for range estimation of speed-related measurements. The sensing receiver estimates the range of speed-related measurements based on the signals received from the first set of sensing resources, thus determining the range of speed-related measurements. For example, the default speed range is -70 to 70 km / h. If the speed measurement value obtained from the signals received from the first set of sensing resources is greater than 0, the sensing receiver can determine the speed range as 0 to 70 km / h. If the speed measurement value obtained from the signals received from the first set of sensing resources is less than 0, the speed range can be determined as -70 to 0 km / h. The second set of sensing resources is used for measuring speed-related measurements. After determining the range of speed-related measurements based on the first set of sensing resources, the sensing receiver preprocesses the received signals from the second set of sensing resources based on this range, and then determines the measured value of the speed-related measurements based on the preprocessed received signals.

[0314] In some embodiments, the relevant configuration parameters of the sensing resource include one or more of the following: sequence index; number of time-domain symbols; time-domain symbol interval; and starting symbol position.

[0315] In some embodiments, the symbol interval of the first group of sensing resources is smaller than the symbol interval of the second group of sensing resources, and the occupancy time of the first group of sensing resources is smaller than the occupancy time of the second group of sensing resources.

[0316] In some embodiments, the first set of sensing resources are aperiodic sensing resources, and the second set of sensing resources are periodic sensing resources. In some embodiments, the sensing receiver can determine the range of velocity-related measurements based on the first set of aperiodic sensing resources, preprocess the first received sensing signal on the second set of periodic sensing resources based on that range, and then determine the measured value of the velocity-related measurements based on the preprocessed sensing signal.

[0317] In some embodiments, the first set includes a sensing resource configuration sequence index, the number of time-domain symbols, the time-domain symbol interval, and the starting symbol position; the second set includes a sensing resource configuration sequence index, the number of time-domain symbols, the time-domain symbol interval, the starting symbol position, and the transmission period.

[0318] In some embodiments, the method further includes:

[0319] In the case of multiple perceptions, the range of velocity-type measurements corresponding to the nth perception is determined based on the measured values ​​of velocity-type measurements determined by at least one perception prior to the nth perception, where n is an integer greater than 1.

[0320] Specifically, in scenarios involving multiple sensing operations (such as target object tracking), the sensing receiver can determine the range of velocity-related measurements corresponding to the nth sensing operation based on the measured values ​​of velocity-related measurements determined in the (n-1)th sensing operation; alternatively, the sensing receiver can determine the range of velocity-related measurements corresponding to the nth sensing operation based on the measured values ​​of velocity-related measurements determined in the previous N (N>1) sensing operations (nNth, ..., n-2th, n-1th). For example, the sensing receiver can use the measurement result of the (n-1)th sensing operation or the average value of the previous n-1 measurement results as the basis for judging or calculating the range of velocity-related measurements in the nth sensing operation.

[0321] In some embodiments, the method further includes:

[0322] Report the measured values ​​of velocity-type measurements to the sensing entity; or...

[0323] Report the measured value of a velocity-type measurement, along with the offset value or range of the velocity-type measurement associated with that value, to the sensing functional entity; or,

[0324] Based on the measured value of velocity-type measurement and the offset value or range of velocity-type measurement associated with the measured value, the velocity of the perceived target is determined, and then the velocity of the perceived target is reported to the perception function entity.

[0325] Specifically, after the sensing receiver determines the measured value of a velocity-type measurement, it can report the measured value to the sensing function entity, or report the measured value and the offset value or range of the velocity-type measurement associated with the measured value to the sensing function entity. In this case, the sensing function entity determines the actual velocity or Doppler frequency offset of the sensing target based on the information reported by the sensing receiver.

[0326] In some embodiments, after the sensing receiver determines the measured value of a velocity-type measurement, it can determine the actual velocity or Doppler frequency offset of the sensing target based on the measured value and the offset value or range of the velocity-type measurement associated with the measured value, and then report the actual velocity or Doppler frequency offset of the sensing target to the sensing functional entity.

[0327] Figure 3 This is a second flowchart illustrating the speed measurement method provided in this application embodiment. The method is applied to a sensing transmitter, such as... Figure 3 As shown, the method includes the following steps:

[0328] Step 300: Preprocess the sensing and transmitting signal based on the offset value or range of velocity-type measurements, where velocity-type measurements are velocity or Doppler frequency offset.

[0329] Step 301: Send the preprocessed sensing signal.

[0330] Specifically, the sensed transmission signal refers to the original transmission signal. In this embodiment, the sensed transmitting end first preprocesses the sensed transmission signal based on the offset value or range of the velocity-type measurement, and then transmits the preprocessed sensed transmission signal. The specific form of the preprocessing is not limited in this application. In some embodiments, the sensed received signal may be multiplied by a formula (function or expression), which is constructed based on the offset value or range of the velocity-type measurement.

[0331] The offset or range of velocity measurements can be configured by the sensing entity, determined by the sensing transmitter, or obtained in other ways; there are no restrictions here.

[0332] In some embodiments, preprocessing the sensed transmitted signal based on the velocity offset value may involve multiplying the sensed transmitted signal by... Where v L The offset value represents the velocity, and μ represents the time index of the signal sequence, μ = 0, ..., N′. t -1, N′ t Based on the maximum perceived speed v′ max The number of symbols required in the time domain, v′, is calculated. max Based on v L The adjusted maximum perceived speed.

[0333] In some embodiments, preprocessing of the sensed transmitted signal based on the offset value or range of velocity-type measurements includes:

[0334] The second velocity or the second Doppler frequency offset is determined based on the range of velocity-type measurements.

[0335] Preprocessing of the sensing transmission signal based on the second velocity or the second Doppler frequency offset.

[0336] Specifically, preprocessing the sensed transmission signal based on the range of velocity-related measurements can involve first determining a second velocity or a second Doppler frequency offset based on the range of velocity-related measurements, and then preprocessing the sensed transmission signal based on this second velocity or second Doppler frequency offset. The specific second velocity or second Doppler frequency offset is not limited; it can be a certain velocity value or a certain Doppler frequency offset value determined based on the range of velocity-related measurements. For example, if the velocity range is 0–70 km / h, the second velocity determined based on this velocity range could be half of the maximum velocity, i.e., 35 km / h.

[0337] This application does not limit the specific form of preprocessing the sensing and transmitting signal based on the second velocity or the second Doppler frequency offset. In some embodiments, the preprocessing of the sensing and transmitting signal based on the velocity offset value described above can be similar, by multiplying the sensing and transmitting signal by a term (function or expression) constructed based on the second velocity or the second Doppler frequency offset. For example, multiplying the sensing and transmitting signal by... v2 represents the second velocity.

[0338] In this embodiment, after the sensing receiver receives the sensing signal, it does not need to preprocess the sensing signal. It can directly calculate the measured value of the speed-type measurement based on the sensing signal. The specific calculation method can refer to the existing technical solution and is not limited here.

[0339] The actual velocity or Doppler frequency offset of the sensed target can be determined based on the measured value and offset value (or second velocity, second Doppler frequency offset) of velocity-related measurements. For example, the actual velocity of the sensed target can be obtained by adding the velocity measurement value to the velocity offset value (or the second velocity).

[0340] The following uses the DFT velocimetry algorithm as an example to illustrate the specific implementation process.

[0341] In existing speed measurement, the sensing and receiving signal I r The relationship between (μ) and the sensed transmitted signal I(μ) is as follows:

[0342]

[0343] Multiply the transmitted sensing signal I(μ) by (Taking velocity-based offset preprocessing as an example) The transmitted signal is denoted as I′(μ), and the received signal is... The sensing receiver still calculates the signal as I(μ), which is denoted as I here. ′ div (μ), as follows:

[0344]

[0345] to I ′ div (μ) Perform DFT operation:

[0346]

[0347] The DFT result will have one or more peaks, and the DFT sequence number of the peak is used. peak The velocity measurement value v′ can be calculated:

[0348]

[0349] The actual velocity of the perceived target is v = v′ + v L .

[0350] Since velocity and Doppler frequency deviation can be converted, if the measured value is the Doppler frequency deviation, then:

[0351]

[0352] The actual Doppler frequency offset of the perceived target is fd = fd′ + fd L , where fd L This represents the offset value of the Doppler frequency shift.

[0353] The speed measurement method provided in this application preprocesses the sensing and transmitting signal based on the offset value or range of speed-related measurement quantities at the sensing and transmitting end, and then transmits the preprocessed sensing and transmitting signal. This can support a larger speed range under the same resolution and symbol configuration, or reduce the number of symbols occupied under the same resolution and speed range. This makes the maximum speed measurement value not limited by the time domain resource configuration (symbol interval, measurement time length), and allows for flexible adjustment of resource configuration, thereby improving the flexibility of measurement resource configuration and reducing the waste of air interface resources.

[0354] In some embodiments, the method further includes:

[0355] Based on the measurement parameters configured by the sensing functional entity, determine the offset value or range of velocity-type measurement quantities;

[0356] The parameters related to the measurement quantity include one or more of the following:

[0357] Speed ​​range;

[0358] Doppler frequency offset range;

[0359] Velocity offset value;

[0360] Doppler frequency offset value.

[0361] Specifically, the sensing function entity can configure one or more of the following to the sensing transmitter: velocity range, Doppler frequency offset range, velocity offset value, and Doppler frequency offset value. The sensing transmitter determines the offset value or range of velocity-related measurements based on the measurement parameters configured by the sensing function entity.

[0362] The sensing entity can predetermine the speed (Doppler frequency offset) range according to the measurement requirements of different sensing nodes. For example, the speed (Doppler frequency offset) range of sensing node A can be set to 0 to 70 km / h (0 to 600 Hz), and the speed (Doppler frequency offset) range of sensing node B can be set to -70 to 0 km / h (-600 to 0 Hz). Then, the speed (Doppler frequency offset) range can be configured to the corresponding sensing nodes.

[0363] In some embodiments, the configuration methods for measurement-related parameters include:

[0364] Configure the set of parameters related to the measurement quantity through high-level parameter configuration; or,

[0365] Add configuration information for measurement-related parameters to the media access control layer signaling used to configure sensing resources.

[0366] Specifically, when a sensing entity configures measurement-related parameters to a sensing node, there are two different methods. One is to configure an optional set of measurement-related parameters through higher-level parameters, and the other is to add the configuration information of the measurement-related parameters to the MAC layer signaling used to configure sensing resources.

[0367] For example, the optional set of speed ranges {0:0~70, 1:-70~0} can be configured through the high-level parameter ISAC_speed_range.

[0368] For example, the MAC layer signaling used to configure sensing resources includes the field ISAC_speed_range{0:0~70, 1:-70~0}, which is used to configure the speed range.

[0369] In some embodiments, the measurement-related parameters are configured based on sensing nodes or sensing node groups; or, the measurement-related parameters are configured based on measurement settings.

[0370] Specifically, in some embodiments, when the sensing function entity configures measurement-related parameters to the sensing node, it can configure them based on the sensing node or sensing node group. That is, each sensing node or each sensing node group is configured with its own measurement-related parameters, and the configured measurement-related parameters are associated with the corresponding sensing node identifier or sensing node group identifier.

[0371] In some embodiments, when the sensing functional entity configures measurement-related parameters to the sensing node, it can be based on the measurement configuration, that is, the measurement-related parameters are configured separately for each measurement, and all sensing nodes in a measurement share the same configuration of measurement-related parameters.

[0372] For example, when configuring an optional set of measurement parameters through high-level parameters, the high-level parameters can be configured based on sensing nodes (groups): each sensing node (group) is configured with its own high-level parameter ISAC_speed_range{0:0~70, 1:-70~0} (ISAC_doppler_range{0:0~600, 1:-600~0}) or ISAC_speed_offset{0:35, 1:-35} (ISAC_doppler_offset{0:300, 1:-300}). This parameter is per point(s) and has a corresponding sensing node (group) identifier (Identifier, ID): ISAC_point(s)ID. Alternatively, based on measurement configuration using high-level parameters: configure a common high-level parameter ISAC_speed_range{0:0~70, 1:-70~0} (ISAC_doppler_range{0:0~600, 1:-600~0}) or ISAC_speed_offset{0:35, 1:-35} (ISAC_doppler_offset{0:300, 1:-300}) for all sensing nodes for each measurement. This parameter is of the common nature.

[0373] For example, when adding configuration information for measurement-related parameters in the MAC layer signaling used to configure sensing resources, configuration can be based on sensing nodes (groups) through MAC layer control signaling: each sensing node (group) is instructed to include the following fields in its respective MAC layer signaling: ISAC_speed_range{0:0~70, 1:-70~0} (ISAC_doppler_range{0:0~600, 1:-600~0}) or ISAC_speed_offset{0:35, 1:-35} (ISAC_doppler_offset{0:300, 1:-300}). The signaling contains the corresponding sensing node (group) ID: ISAC_point(s)ID, which can be added to the MAC layer signaling for resource configuration. Alternatively, based on the measurement configuration, control signaling at the MAC layer can be used to indicate a common control signaling field for each measurement: ISAC_speed_range{0:0~70, 1:-70~0} (ISAC_doppler_range{0:0~600, 1:-600~0}) or ISAC_speed_offset{0:35, 1:-35} (ISAC_doppler_offset{0:300, 1:-300}). This field can be added to the MAC layer signaling in the resource configuration.

[0374] In some embodiments, the method further includes:

[0375] The transmit power of the sensed signal is determined based on the first power adjustment parameter configured by the sensing functional entity; or,

[0376] The transmission power of the sensing signal is determined based on the number of resource units occupied by the sensing signal.

[0377] Specifically, when processing signals based on offset values ​​or ranges of velocity-related measurements, the sensing transmitter can use different Resource Element (RE) powers to transmit the sensing signal. For example, for signals employing velocity shifting, since the number of REs is reduced, higher power can be used for transmission. In this application, velocity shifting refers to processing signals based on offset values ​​or ranges of velocity.

[0378] The first power adjustment parameter can be a power adjustment parameter configured for "processing signals based on the offset value or range of velocity-type measurements". For example, assuming that power P1 is applied to the signal RE power without velocity shifting, and power P2 is applied to the signal RE power with velocity shifting, then SF can configure the first power adjustment parameter to calculate power P2.

[0379] In some embodiments, the sensing transmitter can make a calculation based on the actual amount of resources used. For example, if the number of REs occupied by the signal using speed shifting is half that of the signal not using speed shifting, the power can be adjusted to twice that of the signal not using speed shifting.

[0380] Figure 4 This is the third flowchart illustrating the speed measurement method provided in the embodiments of this application. This method is applied to sensing functional entities, such as... Figure 4 As shown, the method includes the following steps:

[0381] Step 400: Configure measurement-related parameters to the sensing node. The measurement-related parameters include one or more of the following: velocity range; Doppler frequency offset range; velocity offset value; Doppler frequency offset value.

[0382] Specifically, the sensing functional entity can configure one or more of the following to the sensing node (sensing transmitter and / or sensing receiver): velocity range, Doppler frequency offset range, velocity offset value, and Doppler frequency offset value. The sensing transmitter or sensing receiver determines the offset value or range of velocity-related measurements based on the measurement-related parameters configured by the sensing functional entity.

[0383] The sensing entity can predetermine the speed (Doppler frequency offset) range according to the measurement requirements of different sensing nodes. For example, the speed (Doppler frequency offset) range of sensing node A can be set to 0 to 70 km / h (0 to 600 Hz), and the speed (Doppler frequency offset) range of sensing node B can be set to -70 to 0 km / h (-600 to 0 Hz). Then, the speed (Doppler frequency offset) range can be configured to the corresponding sensing nodes.

[0384] In some embodiments, the configuration methods for measurement-related parameters include:

[0385] Configure the set of parameters related to the measurement quantity through high-level parameter configuration; or,

[0386] Add configuration information for measurement-related parameters to the media access control layer signaling used to configure sensing resources.

[0387] Specifically, when a sensing entity configures measurement-related parameters to a sensing node, there are two different methods. One is to configure an optional set of measurement-related parameters through higher-level parameters, and the other is to add the configuration information of the measurement-related parameters to the MAC layer signaling used to configure sensing resources.

[0388] For example, the optional set of speed ranges {0:0~70, 1:-70~0} can be configured through the high-level parameter ISAC_speed_range.

[0389] For example, the MAC layer signaling used to configure sensing resources includes the field ISAC_speed_range{0:0~70, 1:-70~0}, which is used to configure the speed range.

[0390] In some embodiments, the measurement-related parameters are configured based on sensing nodes or sensing node groups; or, the measurement-related parameters are configured based on measurement settings.

[0391] Specifically, in some embodiments, when the sensing function entity configures measurement-related parameters to the sensing node, it can configure them based on the sensing node or sensing node group. That is, each sensing node or each sensing node group is configured with its own measurement-related parameters, and the configured measurement-related parameters are associated with the corresponding sensing node identifier or sensing node group identifier.

[0392] In some embodiments, when the sensing functional entity configures measurement-related parameters to the sensing node, it can be based on the measurement configuration, that is, the measurement-related parameters are configured separately for each measurement, and all sensing nodes in a measurement share the same configuration of measurement-related parameters.

[0393] For example, when configuring an optional set of measurement parameters through high-level parameters, the high-level parameters can be configured based on sensing nodes (groups): each sensing node (group) is configured with its own high-level parameter ISAC_speed_range{0:0~70, 1:-70~0} (ISAC_doppler_range{0:0~600, 1:-600~0}) or ISAC_speed_offset{0:35, 1:-35} (ISAC_doppler_offset{0:300, 1:-300}). This parameter is per point(s) and has a corresponding sensing node (group) identifier (Identifier, ID): ISAC_point(s)ID. Alternatively, based on measurement configuration using high-level parameters: configure a common high-level parameter ISAC_speed_range{0:0~70, 1:-70~0} (ISAC_doppler_range{0:0~600, 1:-600~0}) or ISAC_speed_offset{0:35, 1:-35} (ISAC_doppler_offset{0:300, 1:-300}) for all sensing nodes for each measurement. This parameter is of the common nature.

[0394] For example, when adding configuration information for measurement-related parameters in the MAC layer signaling used to configure sensing resources, configuration can be based on sensing nodes (groups) through MAC layer control signaling: each sensing node (group) is instructed to include the following fields in its respective MAC layer signaling: ISAC_speed_range{0:0~70, 1:-70~0} (ISAC_doppler_range{0:0~600, 1:-600~0}) or ISAC_speed_offset{0:35, 1:-35} (ISAC_doppler_offset{0:300, 1:-300}). The signaling contains the corresponding sensing node (group) ID: ISAC_point(s)ID, which can be added to the MAC layer signaling for resource configuration. Alternatively, based on the measurement configuration, control signaling at the MAC layer can be used to indicate a common control signaling field for each measurement: ISAC_speed_range{0:0~70, 1:-70~0} (ISAC_doppler_range{0:0~600, 1:-600~0}) or ISAC_speed_offset{0:35, 1:-35} (ISAC_doppler_offset{0:300, 1:-300}). This field can be added to the MAC layer signaling in the resource configuration.

[0395] In some embodiments, when multiple velocity ranges or multiple Doppler frequency offset ranges are configured for the same sensing node, there is an overlap between the multiple velocity ranges or multiple Doppler frequency offset ranges.

[0396] Specifically, if the perceived velocity of the target is at the boundary of two velocity ranges, a velocity measurement ambiguity problem may occur, meaning that the object's velocity range may be selected back and forth between the two velocity ranges. To solve this problem, the following method can be used: the velocity range configuration has overlapping parts. For example, the configurable values ​​of the velocity range can be set as: {0:-10~70, 1:-70~10}. In practice, when the radial velocity of the object is greater than 0, velocity range 0 (i.e., -10~70) is selected, and when it is less than 0, velocity range 1 (i.e., -70~10) is selected.

[0397] In some embodiments, configuring measurement-related parameters to the sensing node further includes:

[0398] Configure the effective time information of the measurement parameters to the sensing nodes.

[0399] Specifically, the sensing entity can configure the validity period information for the measured parameters along with the parameters themselves. For example, a validity period can be configured for the speed range. Within the validity period, the speed range is assumed to remain unchanged. After the validity period, the speed range needs to be reconfigured; otherwise, it reverts to the default range. For instance, the default speed range can be preset to {-70 to 70}. By configuring the validity period, the problem of speed measurement ambiguity can be solved.

[0400] The methods provided in the various embodiments of this application are based on the same concept, so the implementation of each method can be referred to each other, and repeated parts will not be described again.

[0401] The methods provided in the above embodiments of this application are illustrated below through examples of specific application scenarios.

[0402] Example 1: SF configures a speed range, and the sensing transmitter processes the signal according to the speed range.

[0403] Step 1-1: Configure the speed range for the sensing transmitter in SF. For example, the speed range ISAC_speed_range = 0 (0~70km / h).

[0404] Step 1-2: The SF notifies the sensing sender to process according to the speed range. This step can also be combined into step 1-1, by configuring the speed range to implicitly notify the sensing sender to process according to the speed range.

[0405] Steps 1-3: The sensing transmitter allocates sensing resources according to the speed range and notifies the sensing receiver of the resource allocation information and the original sequence information. This requires configuring the sequence index, number of time-domain symbols, time-domain symbol interval, and start symbol position.

[0406] Steps 1-4: The sensing and transmitting end pre-transforms the original sequence and then sends the transformed sequence.

[0407] Steps 1-5: The sensing receiver obtains the received sequence based on the received sensing resource allocation information, uses the received sequence and the original sequence to perform speed measurement, and reports the speed measurement result (speed measurement value) to SF.

[0408] Steps 1-6: SF processes the received speed measurement results and speed range information to obtain the true speed (actual speed of the perceived target) information.

[0409] Among them, steps 1-1, 1-2, and 1-6 are implemented by SF, steps 1-3 and 1-4 are implemented by the sensing transmitter, and step 1-5 is implemented by the sensing receiver.

[0410] Example 2: SF configures a speed range, and the sensing receiver processes the signal according to the speed range.

[0411] Step 2-1: Configure the speed range for the sensing transmitter and the sensing receiver. For example, the speed range ISAC_speed_range = 0 (0~70km / h).

[0412] Step 2-2: SF notifies the sensing transmitter and receiver to process according to the speed range. This step can also be combined with step 2-1, implicitly notifying the sensing transmitter and receiver to process according to the speed range by configuring the speed range.

[0413] Steps 2-3: The sensing transmitter allocates sensing resources according to the speed range and notifies the sensing receiver of the resource allocation information and the original sequence information. This requires configuring the sequence index, number of time-domain symbols, time-domain symbol interval, and start symbol position.

[0414] Steps 2-4: The sensing end sends the original sequence.

[0415] Steps 2-5: The sensing receiver obtains the received sequence based on the received sensing resource allocation information, performs a pre-transformation on the received sequence, and then uses the transformed received sequence and the original sequence to measure the speed.

[0416] Steps 2-6: The sensing receiver processes the speed measurement results based on the speed range information to obtain the true speed information, and then reports the true speed information to SF.

[0417] Steps 2-1 and 2-2 are implemented by SF, steps 2-3 and 2-4 are implemented by the sensing transmitter, and steps 2-5 and 2-6 are implemented by the sensing receiver.

[0418] Example 3: The sensing receiver obtains the speed range through coarse measurement, and then processes the signal based on the speed range.

[0419] Step 3-1: The sensing transmitter configures two sets of sensing resources for a single sensing operation. This requires configuring the sequence index, number of time-domain symbols, time-domain symbol interval, and start symbol position. The first set of sensing resources and the transmission sequence are used for velocity range measurement (small symbol interval, short duration), and the second set of sensing resources and the transmission sequence are used for velocity measurement (large symbol interval, long duration). The transmitter then notifies the sensing receiver of the configuration of both sets of sensing resources. The transmission times of the two sets of sensing resources are configured by the sensing transmitter, with the transmission time of the first set of sensing resources being earlier than that of the second set.

[0420] Step 3-2: The sensing receiver performs speed range measurement based on the transmitted signals received from the first set of sensing resources.

[0421] Step 3-3: The sensing receiver pre-transforms the sequence on the second set of sensing resources received after the speed range is measured, and then uses the transformed received sequence to measure the speed.

[0422] Steps 3-4: The sensing receiver reports the speed range and speed measurement results to the SF.

[0423] Step 3-1 is implemented at the sensing transmitter, and steps 3-2, 3-3, and 3-4 are implemented at the sensing receiver.

[0424] Example 4: The sensing receiver obtains the speed range through coarse measurement and tracking, and processes the signal according to the speed range.

[0425] Step 4-1: The sensing transmitter configures two sets of sensing resources for a single sensing operation. One set of aperiodic sensing resources is used for velocity range measurement, requiring configuration of the sequence index, number of time-domain symbols, time-domain symbol interval, and start symbol position. The other set of periodic sensing resources is used for velocity measurement, requiring configuration of the sequence index, number of time-domain symbols, time-domain symbol interval, start symbol position, and transmission period.

[0426] Step 4-2: Based on the speed range measured by the first group of aperiodic sensing resources, the sensing receiver pre-transforms the sequence first received on the second group of periodic sensing resources, and then uses the transformed received sequence to measure the speed.

[0427] Step 4-3: The sensing receiver reports the speed range and speed measurement results to the SF.

[0428] Step 4-4: The sensing receiver calculates the speed range for the nth measurement based on the historical speed measurement results. For example, the sensing node can use the measurement result of the (n-1)th measurement or the average of the previous (n-1) measurement results as the basis for judging or calculating the speed range for the nth measurement.

[0429] Steps 4-5: The sensing receiver pre-transforms the sequence received in the nth cycle on the sensing resources of the second period according to the speed range of the nth time, and then uses the transformed received sequence to measure the speed.

[0430] Steps 4-6: The sensing receiver reports the speed range and speed measurement result for the nth time to the SF. This process is repeated throughout the entire cycle.

[0431] Step 4-1 is implemented at the sensing transmitter, and steps 4-2, 4-3, 4-4, 4-5, and 4-6 are implemented at the sensing receiver.

[0432] The methods and apparatuses provided in the various embodiments of this application are based on the same concept. Since the methods and apparatuses solve problems in similar ways, the implementations of the apparatuses and methods can refer to each other, and repeated details will not be repeated.
