[0002] This disclosure claims priority to Chinese Patent Application No. 202411630571.3, filed in China on November 14, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of communication sensing technology, and in particular to a communication method, sensing entity, sensing node, storage medium, and program product. Background Technology

[0004] Networked sensing integration is a key technology for 6G (6th Generation Mobile Communication Technology). Utilizing communication / sensing signals for sensing can support new services such as target detection, high-precision positioning, environmental reconstruction, and imaging. It can be widely applied in scenarios such as indoor positioning, drones, smart vehicles, and the Internet of Things (IoT), facilitating the interconnection of everything. Similar to a radar system, the base station first sends sensing signals to targets both on and off the network, and then uses a sensing receiver to receive the echo signals. By extracting and processing the echo information, sensing functions such as target detection, positioning, imaging, recognition, and tracking are achieved.

[0005] Currently, when performing target perception, although measurement quantities are defined, they are usually fixed and uniform, which have low flexibility, make it difficult to meet the needs of various perception scenarios, and result in low resource utilization. Summary of the Invention

[0116] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this disclosure.

[0117] The technical solutions of this disclosure and how they solve the aforementioned technical problems will be described in detail below through embodiments and in conjunction with the accompanying drawings. The embodiments below can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0118] Furthermore, the technical solutions described in the embodiments of this disclosure can be combined arbitrarily without conflict.

[0119] This disclosure provides a communication method implemented through sensing entities and sensing nodes, which will be described in detail below from the perspective of sensing entities and sensing nodes.

[0120] Figure 1 is a flowchart illustrating a communication method provided in an embodiment of this disclosure. As shown in Figure 1, in this embodiment, the communication method applied to a sensing entity mainly includes the following steps:

[0121] S101. Configure N measurement quantity combinations to the sensing node; where N is a positive integer, different measurement quantity combinations correspond to different sensing requirements, and each measurement quantity combination includes one or more measurement quantities.

[0122] In embodiments of this disclosure, the sensing entity can configure N combinations of measurement quantities to the sensing node.

[0123] It is understood that in the embodiments of this disclosure, different combinations of measurement quantities correspond to different perception requirements, thereby supporting perception tasks in different perception scenarios. Different combinations of measurement quantities can be defined or configured according to different perception requirements to meet diverse perception needs.

[0124] It should be noted that, in the embodiments of this disclosure, the number of measurement quantity combinations configured by the sensing entity to the sensing node, and the number of measurement quantities included in each measurement quantity combination, can be set according to actual needs and application scenarios, and are not limited in the embodiments of this disclosure.

[0125] In embodiments of this disclosure, each combination of measurements includes one or more of the following measurements: signal quality of the sensing path, signal quality of a feature on the sensing path, and magnitude of a feature on the sensing path; wherein the feature includes one or more of the following: time delay, angle, and Doppler velocity.

[0126] It should be noted that, in the embodiments of this disclosure, other measurement quantities may be added to the measurement quantity combination compared to the measurement quantities already defined in the existing protocol.

[0127] It should be noted that, in the embodiments of this disclosure, compared with existing communication measurements such as Reference Signal Receiving Power (RSRP) / Signal to Interference plus Noise Ratio (SINR), the measurement combination can add RSRPP / SINRP to represent the signal quality of the sensing path, and can also add RSRPM / SINRM to represent the signal quality of features on the sensing path. Here, features refer to time delay, angle, Doppler velocity, etc. In addition, the magnitude of features on the sensing path can also be added, including but not limited to the magnitude of Doppler velocity, that is, the velocity measurement of the sensing target is added.

[0128] It should be noted that in communication, the measured quantities RSRP and SINR mainly reflect the signal quality of the reference signal. However, in sensing requirements, the cell or terminal is not selected based on the signal quality of the reference signal, but rather various sensing information is measured, such as the signal quality of different sensing paths, and the signal quality of time delay, angle, etc. on each sensing path. Based on this, the measured quantities in the combination of measured quantities proposed in this disclosure can better adapt to sensing requirements.

[0129] In embodiments of this disclosure, the sensing entity may perform the following steps for a combination of measurement quantities: based on the corresponding sensing requirements, configure the priority of each combination of measurement quantities that includes different measurement quantities.

[0130] It is understood that, in the embodiments of this disclosure, for different sensing needs, the importance of different measurement quantities in the corresponding measurement quantity combinations varies. Based on this, the sensing entity can configure the measurement quantity combination and the priority of the measurement quantities according to the sensing needs for each measurement quantity combination.

[0131] In embodiments of this disclosure, in each combination of measurements, the different measurements can be arranged in descending order of priority.

[0132] It should be noted that, in the embodiments of this disclosure, the sensing entity can select several measurement quantities from the set of measurement quantities according to sensing needs, and sort the selected measurement quantities according to priority. Arranging the measurement quantities in the combination of measurement quantities from high to low priority is only one feasible way to reflect the priority of the measurement quantities. Of course, they can also be arranged from low to high priority, and the priority order of the measurement quantities can be reflected in other forms. This disclosure does not limit this approach.

[0133] For example, in embodiments of this disclosure, the sensing entity is configured with different combinations of measurement quantities. These combinations not only reflect the sensing requirements but also the priority of different measurement quantities. These combinations include:

[0134] Ranging requirements: RSRPP / SINRP / RSRPM / SINRM-TOA / TDOA;

[0135] Speed ​​measurement requirements: RSRPP / SINRP / RSRPM / SINRM-Doppler;

[0142] Angle measurement + velocity measurement requirements: RSRPP / SINRP / RSRPM / SINRM-AOA / DOA-Doppler;

[0143] Distance measurement + speed measurement + angle measurement requirements:

[0144] RSRPP / SINRP / RSRPM / SINRM-TOA / TDOA-Doppler-AOA / DOA;

[0145] Distance measurement + angle measurement + speed measurement requirements:

[0146] RSRPP / SINRP / RSRPM / SINRM-TOA / TDOA-AOA / DOA-Doppler;

[0147] Speed ​​measurement + distance measurement + angle measurement requirements:

[0148] RSRPP / SINRP / RSRPM / SINRM-Doppler-TOA / TDOA-AOA / DOA;

[0149] Speed ​​measurement + angle measurement + distance measurement requirements:

[0150] RSRPP / SINRP / RSRPM / SINRM-Doppler-AOA / DOA-TOA / TDOA;

[0151] Angle measurement + distance measurement + speed measurement requirements:

[0152] RSRPP / SINRP / RSRPM / SINRM-AOA / DOA-TOA / TDOA-Doppler;

[0153] Angle measurement + velocity measurement + distance measurement requirements:

[0154] RSRPP / SINRP / RSRPM / SINRM-AOA / DOA-Doppler-TOA / TDOA;

[0155] DOA represents the direction of arrival, AOA represents the angle of arrival, TOA represents the time of arrival, TDOA represents the time difference of arrival, and Doppler represents Doppler-related measurements such as Doppler frequency shift and Doppler velocity. The signaling representation is as follows:

[0172] }

[0173] It should be noted that, in the embodiments of this disclosure, the range and minimum interval of each measurement can be obtained through existing protocols (e.g., Tc, 1dB, 0.1°). For velocity measurements, velocity resolution and maximum velocity range are added to represent this measurement. Furthermore, in addition to the measurements required for sensing needs, each combination of measurements includes signal quality measurements RSRPP / SINRP / RSRPM / SINRM. This is primarily because the accuracy of sensing path / measurement varies significantly under different signal qualities; using signal quality to evaluate the confidence level of the path / measurement yields more accurate sensing results.

[0174] It should be noted that, in the embodiments of this disclosure, referring to the examples above, in each combination of measurement quantities, different measurement quantities can be arranged in descending order of priority. Based on this, the measurement quantities in the combination / configuration of measurement quantities also represent the priority of different measurement quantities, with the measurement quantities at the beginning having higher priority. For example, when the perception requirement is mainly to detect the distance of the target, the distance measurement requirement has a higher priority; when the perception requirement is mainly to detect moving targets, the velocity measurement requirement has a higher priority; when the perception requirement is mainly to determine the direction of the target, the angle measurement requirement has a higher priority.

[0175] In the embodiments of this disclosure, the sensing entity can configure not only the priority of the measurement quantity, but also the priority of the sensing path. The sensing entity can also perform the following steps: configuring the priority of different sensing paths under different sensing requirements.

[0176] It should be noted that, in the embodiments of this disclosure, the priority of a sensing path may be different under different sensing requirements. The sensing entity can configure the priority of a sensing path under different sensing requirements. Since there can be multiple sensing paths, the sensing entity can configure the priority of different sensing paths under different sensing requirements. The specific sorting rules can be set according to the actual application scenario, and are not limited in the embodiments of this disclosure.

[0177] For example, in embodiments of this disclosure, the sensing entity (SF) defines different path sequences based on different sensing needs. These include, but are not limited to, the following rules:

[0178] When ranging is the primary requirement: multiple sensing paths can be sorted according to the RSRP size of different sensing paths, the order of different paths from near to far (focusing on near targets), or the order of different sensing paths from far to near (focusing on far targets);

[0179] When speed measurement is the primary requirement: multiple sensing paths can be sorted according to the RSRP values ​​of different sensing paths, the speed of different sensing paths from largest to smallest (for moving targets), or the speed of different sensing paths from smallest to largest (for stationary targets).

[0180] When angle measurement is the primary requirement: multiple sensing paths can be sorted in order of RSRP size, angle from smallest to largest, or angle from largest to smallest (depending on the target area).

[0181] In the embodiments of this disclosure, after performing the above step S101, i.e., configuring N measurement quantity combinations to the sensing node, the sensing entity may further perform the following steps: receiving a first message sent by the sensing node; wherein, the first message is used to indicate the sensing node's support for each of the N measurement quantity combinations; if N equals 1, and the first message indicates that the sensing node supports a configured measurement quantity combination, the configured measurement quantity combination is determined as the first measurement quantity combination to be used by the sensing node; if N is greater than 1, based on the first message, a measurement quantity combination supported by the sensing node is selected from the N measurement quantity combinations, determined as the first measurement quantity combination, and the first measurement quantity combination is indicated to the sensing node.

[0182] It is understood that in the embodiments of this disclosure, the sensing entity configures N combinations of measurement quantities to the sensing node. Correspondingly, the sensing node can inform the sensing entity of its support for these N combinations of measurement quantities through a first message. This helps the sensing entity understand the capabilities of the sensing node, thereby making a more appropriate configuration and determining the first combination of measurement quantities to be used by the sensing node.

[0183] It should be noted that, in the embodiments of this disclosure, if the sensing entity configures only one measurement quantity combination to the sensing node (i.e., N equals 1), and the sensing node supports this measurement quantity combination, then this measurement quantity combination is determined as the first measurement quantity combination, and subsequent sensing nodes will use this measurement quantity combination. If the sensing entity configures multiple measurement quantity combinations to the sensing node (i.e., N is greater than 1), the sensing entity can select a measurement quantity combination supported by the sensing node based on the sensing node's support for these measurement quantity combinations, and instruct the sensing node to use this measurement quantity combination subsequently. Furthermore, if the sensing node does not support all the measurement quantity combinations configured by the sensing entity, the sensing entity can reconfigure other measurement quantity combinations for the sensing node and continue to determine the first measurement quantity combination in the same way.

[0184] In the embodiments of this disclosure, the sensing entity may further perform the following steps: configuring the priority of M sensing paths under the first requirement and / or the priority of K measurements included in the first measurement combination to the sensing node, as well as the reporting order of measurement data of K measurements on different sensing paths in the M sensing paths; wherein M and K are positive integers, and the first requirement is the sensing requirement corresponding to the first measurement combination.

[0185] It should be noted that, in the embodiments of this disclosure, as described above regarding the measurement quantity combinations, the sensing entity can configure N measurement quantity combinations to the sensing node. In each measurement quantity combination, different measurement quantities can be arranged in descending order of priority. The N measurement quantity combinations include a first measurement quantity combination. Based on this, the sensing entity can configure the priority of the K measurement quantities included in the first measurement quantity combination to the sensing node, which can be achieved simultaneously with configuring the first measurement quantity combination, i.e., priority configuration is achieved by setting the order of the measurement quantities. Of course, the sensing entity can also configure the priority of the K measurement quantities to the sensing node through relevant instructions or messages. This disclosure does not limit this.

[0186] It should be noted that, in the embodiments of this disclosure, as described above regarding the sensing paths, the sensing entity can configure the priorities of different sensing paths under different sensing requirements. Based on this, the sensing entity can configure the priorities of M sensing paths under the first requirement to the sensing node through relevant instructions or messages. This disclosure does not limit this.

[0187] In embodiments of this disclosure, the sensing entity can configure the sensing node with the reporting order of measurement data for K measurements on different sensing paths among M sensing paths. The reporting order of the measurement data is as follows:

[0188] First priority: Sort the M sensing paths in descending order of priority, and prioritize reporting the measurement data of K quantities on different sensing paths in the first m sensing paths.

[0189] Alternatively, the second order is to sort the K measurements in descending order of priority and prioritize reporting the measurement data of the first k measurements on different sensing paths among the M sensing paths.

[0190] Alternatively, the third order: sort the M sensing paths and K measurements in descending order of priority, and prioritize reporting the measurement data of the first k measurements on different sensing paths among the first m sensing paths.

[0191] Where m is a positive integer greater than or equal to 1 and less than M, and k is a positive integer greater than or equal to 1 and less than K.

[0192] The following details the three possible sequences.

[0193] In the embodiments of this disclosure, the sorting problem of K measurements on M sensing paths is first discussed, and two sorting methods are proposed: Sorting method 1: sensing path first, then measurement, that is, the measurement data of all measurements are sorted sequentially according to each sensing path, as shown in Figure 2, where resource info represents some fixed quantities; Sorting method 2: measurement first, then sensing path, that is, the measurement data of each measurement are sorted sequentially according to all sensing paths, as shown in Figure 3, where A s Bs C s Let A, B, and C represent the measurement data of the s-th sensing path in the M sensing paths, respectively, where 1 ≤ s ≤ M, and K are the measurement quantities A, B, ..., X.

[0194] It should be noted that in real-world network environments, there may be insufficient sensing reporting resources. Therefore, it is necessary to consider the priority of sensing paths and / or the priority of measurements. Considering priority, the reported measurement content is divided into Sensing-1 and Sensing-2. Sensing-1 has a fixed size and contains resource info and measurement data of important measurements. If it is not fully occupied, the corresponding bit is set to 0. Resource info includes a sensing resource indicator / sensing resource set indicator field, a beam index field, an indication of the number of paths and / or data compression paths, the existence of Sensing-2, the length of Sensing-2, etc., followed by measurement data of some higher-priority measurements. Sensing-2 includes measurement data of other lower-priority measurements.

[0195] In the embodiments of this disclosure, the first order is as follows: the M sensing paths are sorted in descending order of priority, and the measurement data of K measurements on different sensing paths in the first m sensing paths are reported first. That is, the measurement data of all measurements on the first m sensing paths with higher priority are arranged first to form Sensing-1, and reported first.

[0196] In the embodiments of this disclosure, combining the two sorting methods mentioned above, namely sorting method 1 and sorting method 2, the measurement data of K measurements on different sensing paths in the first order of priority reporting can be specifically divided into two cases. The first order also includes:

[0197] Among the first m sensing paths, the measurement data of the K measurements on the high-priority sensing path are reported before the measurement data of the K measurements on the low-priority sensing path.

[0198] Measurement data of different quantities on the same sensing path are reported in descending order of priority.

[0199] Alternatively, on the first m sensing paths, the measurement data of the higher-priority measurement among the K measurements is reported before the measurement data of the lower-priority measurement.

[0200] Measurement data of the same quantity on different sensing paths are reported from high to low priority according to the sensing path.

[0201] For example, in an embodiment of this disclosure, measurement data of quantities A, B, C, and D on M sensing paths are reported, where A s B s C s D s These represent the measurement data of quantities A, B, C, and D on the s-th sensing path out of M sensing paths, where 1 ≤ s ≤ M. Subsequent examples will use this representation and will not be elaborated further. Referring to Figure 4, Sensing-1 includes fixed parameters such as the number of sensing paths in the resource info, the index, and Sensing-2 indication information; the measurement data of all quantities are sequentially arranged for each of the first m sensing paths. Sensing-2 includes the measurement data of all quantities on the (m+1), (m+2), ..., sensing paths arranged sequentially.

[0202] For example, in an embodiment of this disclosure, referring to Figure 5, Sensing-1 includes: fixed parameters such as the number of sensing paths in resource info, indexes, Sensing-2 indication information, etc.; the first m sensing paths sequentially arrange the measurement data of each measurement quantity. Sensing-2 includes: the (m+1)th, (m+2)th, ... sensing paths sequentially arranging the measurement data of each measurement quantity.

[0203] In the embodiments of this disclosure, the second order is as follows: the K measurements are sorted in descending order of priority, and the measurement data of the first k measurements on different sensing paths in the M sensing paths are reported first. That is, the measurement data of the first k measurements with higher priority on all sensing paths constitute Sensing-1 and are reported first.

[0204] In the embodiments of this disclosure, combining the two sorting methods mentioned above, namely sorting method 1 and sorting method 2, the priority reporting of the measurement data of the first k measurements on different sensing paths among the M sensing paths in the second order can be specifically divided into two cases. The second order also includes:

[0205] In M sensing paths, the measurement data of the first k measurements on the high-priority sensing path are reported before the measurement data of the first k measurements on the low-priority sensing path.

[0206] Measurement data of different quantities on the same sensing path are reported in descending order of priority.

[0207] Alternatively, on M sensing paths, the measurement data of the highest priority measurement among the first k measurements is reported before the measurement data of the lowest priority measurement.

[0208] Measurement data of the same quantity on different sensing paths are reported from high to low priority according to the sensing path.

[0209] For example, in an embodiment of this disclosure, referring to Figure 6, Sensing-1 includes: fixed parameters such as the number of sensing paths in resource info, indexes, Sensing-2 indication information, etc.; and sequentially arranging the measurement data of the top k measurements (k=2) with higher priority for each of the M sensing paths, i.e., measurements A and B. Sensing-2 includes: sequentially arranging the measurement data of the remaining measurements with lower priority for each of the M sensing paths.

[0210] For example, in an embodiment of this disclosure, referring to Figure 7, Sensing-1 includes: fixed parameters such as the number of sensing paths in resource info, index, Sensing-2 indication information; the measurement data of the k highest priority measurements (k=2) among the M sensing paths, namely measurements A and B, are sorted sequentially; Sensing-2 reporting of measurements includes: sorting the measurement data of each of the remaining measurements of the M sensing paths sequentially.

[0211] In the embodiments of this disclosure, the third order is as follows: the M sensing paths and K measurements are sorted in descending order of priority, and the measurement data of the first k measurements on different sensing paths in the first m sensing paths are reported first. That is, the measurement data of the first k measurements on the first m sensing paths with higher priority are arranged first to form Sensing-1, and reported first.

[0212] In the embodiments of this disclosure, combining the two sorting methods mentioned above, namely sorting method 1 and sorting method 2, the measurement data of the first k measurements on different sensing paths in the first m sensing paths that are reported first in the third order can be specifically divided into two cases. The third order also includes:

[0213] Among the first m sensing paths, the measurement data of the first k measurements on the high-priority sensing path are reported before the measurement data of the first k measurements on the low-priority sensing path.

[0214] Measurement data of different quantities on the same sensing path are reported in descending order of priority.

[0215] Alternatively, on the first m sensing paths, the measurement data of the higher-priority measurement among the first k measurements is reported before the measurement data of the lower-priority measurement.

[0216] Measurement data of the same quantity on different sensing paths are reported from high to low priority according to the sensing path.

[0217] For example, in an embodiment of this disclosure, referring to Figure 8, Sensing-1 includes: fixed parameters such as the number of sensing paths in resource info, indexes, Sensing-2 indication information, etc.; the measurement data of the k most important measurements (k=2) among the first m sensing paths, i.e., measurements A and B, are sorted sequentially. Sensing-2 reports the measurements including: the measurement data of the first m sensing paths are sorted sequentially for other measurements, and then the measurement data of the remaining sensing paths are sorted sequentially.

[0218] For example, in an embodiment of this disclosure, referring to Figure 9, Sensing-1 includes: fixed parameters such as the number of sensing paths in resource info, indexes, Sensing-2 indication information, etc.; and sequentially sorts the measurement data of the k more important measurements (k=2), i.e., measurements A and B, on the first m sensing paths. Sensing-2 includes: sequentially sorting the measurement data of the remaining measurements on the first m sensing paths, and then sequentially sorting the measurement data of the measurements on other sensing paths.

[0219] It should be noted that, in the embodiments of this disclosure, the first order, second order and third order mainly define the measurement data that is reported first, namely the measurement data included in Sensing-1, and the related reporting order. For the remaining measurement data, namely the measurement data included in Sensing-2, considering that the importance is low, the sensing nodes can be instructed to report in the order shown in the above example, or the sensing entity and the sensing nodes can negotiate or set other rules or orders for reporting. This disclosure does not limit this.

[0220] Figure 10 is a schematic flowchart of a communication method provided in an embodiment of this disclosure. As shown in Figure 10, in the embodiment of this disclosure, the communication method applied to a sensing node mainly includes the following steps:

[0221] S201. Receive N combinations of measurement quantities configured by the sensing entity; where N is a positive integer, different combinations of measurement quantities correspond to different sensing requirements, and each combination of measurement quantities includes one or more measurement quantities.

[0222] In the embodiments of this disclosure, corresponding to the above-described sensing entity-side method, the sensing node can receive N combinations of measurement quantities configured for the sensing entity.

[0223] In embodiments of this disclosure, in each combination of measurements, the different measurements are arranged in descending order of priority.

[0224] In embodiments of this disclosure, each combination of measurements includes one or more of the following measurements: signal quality of the sensing path, signal quality of a feature on the sensing path, and magnitude of a feature on the sensing path; wherein the feature includes one or more of the following: time delay, angle, and Doppler velocity.

[0225] It should be noted that, in the embodiments of this disclosure, the combination of measurement quantities, measurement quantities, and other explanations of sensing paths are detailed in the relevant content of the above-mentioned sensing entity side method, and will not be repeated here.

[0226] In the embodiments of this disclosure, after the sensing node receives N combinations of measurement quantities configured by the sensing entity, it can perform the following steps: sending a first message to the sensing entity so that the sensing entity can determine the first combination of measurement quantities to be used by the sensing node; wherein, the first message is used to indicate the sensing node's support for each of the N combinations of measurement quantities.

[0227] It is understood that in the embodiments of this disclosure, the sensing capabilities of the sensing nodes are different, and the supported measurement quantity combinations are different. The sensing node may not support some measurement quantity combinations. Based on this, the sensing node can send a first message to the sensing entity to inform it of its support for the configured N measurement quantity combinations. In this way, the sensing entity can know the capabilities of the sensing node, determine the first measurement quantity combination to be used by the sensing node, and then further perform relevant configurations. See the relevant content on the sensing entity side for details.

[0228] In the embodiments of this disclosure, the sensing node may further perform the following steps: receiving the priority of the M sensing paths configured by the sensing entity under the first requirement and / or the priority of the K measurements included in the first measurement combination, as well as the reporting order of the measurement data of the K measurements on different sensing paths in the M sensing paths; wherein M and K are positive integers, and the first requirement is the sensing requirement corresponding to the first measurement combination.

[0229] In the embodiments of this disclosure, the order of measurement data reporting is as follows:

[0230] First priority: Sort the M sensing paths from high to low priority, and prioritize reporting the measurement data of K quantities on different sensing paths in the first m sensing paths.

[0231] Alternatively, the second order is to sort the K measurements in descending order of priority and prioritize reporting the measurement data of the first k measurements on different sensing paths among the M sensing paths.

[0232] Alternatively, the third order: sort the M sensing paths and K measurements according to their priority from high to low, and prioritize reporting the measurement data of the first k measurements on different sensing paths among the first m sensing paths.

[0233] Where m is a positive integer greater than or equal to 1 and less than M, and k is a positive integer greater than or equal to 1 and less than K.

[0234] In embodiments of this disclosure, the first order further includes:

[0235] Among the first m sensing paths, the measurement data of the K measurements on the high-priority sensing path are reported before the measurement data of the K measurements on the low-priority sensing path.

[0236] Measurement data of different quantities on the same sensing path are reported in descending order of priority.

[0237] Alternatively, on the first m sensing paths, the measurement data of the higher-priority measurement among the K measurements is reported before the measurement data of the lower-priority measurement.

[0238] Measurement data of the same quantity on different sensing paths are reported from high to low priority according to the sensing path.

[0239] In embodiments of this disclosure, the second order further includes:

[0240] In M sensing paths, the measurement data of the first k measurements on the high-priority sensing path are reported before the measurement data of the first k measurements on the low-priority sensing path.

[0241] Measurement data of different quantities on the same sensing path are reported in descending order of priority.

[0242] Alternatively, on M sensing paths, the measurement data of the highest priority measurement among the first k measurements is reported before the measurement data of the lowest priority measurement.

[0243] Measurement data of the same quantity on different sensing paths are reported from high to low priority according to the sensing path.

[0244] In embodiments of this disclosure, the third order further includes:

[0245] Among the first m sensing paths, the measurement data of the first k measurements on the high-priority sensing path are reported before the measurement data of the first k measurements on the low-priority sensing path.

[0246] Measurement data of different quantities on the same sensing path are reported in descending order of priority.

[0247] Alternatively, on the first m sensing paths, the measurement data of the higher-priority measurement among the first k measurements is reported before the measurement data of the lower-priority measurement.

[0248] Measurement data of the same quantity on different sensing paths are reported from high to low priority according to the sensing path.

[0249] It should be noted that, in the embodiments disclosed herein, the explanations of the three sequences are detailed in the relevant content of the above-mentioned entity-side perception method, and will not be repeated here.

[0250] In the embodiments of this disclosure, the sensing node may further perform the following steps: based on the priority of the M sensing paths under the first requirement and / or the priority of the K measurements, sort the measurement data of the K measurements on different sensing paths in the M sensing paths according to the order of measurement data reporting, and report them to the sensing entity in sequence.

[0251] It is understood that in the embodiments of this disclosure, the sensing entity configures the measurement data reporting order for the sensing nodes, that is, one of the three orders mentioned above. Based on this, the sensing nodes can report to the sensing nodes in the configured order after obtaining the measurement data of K measurements on different sensing paths in M ​​sensing paths.

[0252] It should be noted that, in the embodiments of this disclosure, the sensing node reports the measurement data to the sensing entity. Specifically, when the sensing node is a terminal, the terminal reports the measurement information to the base station, and then the base station reports the measurement data to the sensing entity; when the sensing node is a base station, the base station reports the measurement data to the sensing entity.

[0253] In embodiments of this disclosure, the sensing node may further perform the following steps: discarding unreported measurement data when the total amount of reported measurement data reaches the maximum amount of data to be transmitted.

[0254] It is understood that, in the embodiments of this disclosure, when resources are sufficient, the sensing node reports measurement data to the sensing entity according to the configured measurement data reporting order. When resources are limited, an intelligent discarding strategy can be introduced. This strategy determines the maximum data transmission volume based on the pre-set measurement data reporting order, the number of available resource elements (REs), and the configured maximum bitrate. When the total amount of reported measurement data reaches the maximum transmission data flow, data that has not yet been reported is automatically discarded. For example, Figure 11 illustrates a data discarding diagram for the reporting of measurement data of a certain type of measurement quantity.

[0255] It should be noted that in the embodiments of this disclosure, the intelligent discard strategy will have a certain impact. If the priority of measurement quantity is given priority when reporting measurement data, some information of sensing path will be discarded, which will cause missed detection. In this case, the sensing signal can be sent again. If the priority of sensing path is given priority, some information of measurement quantity will be discarded. In this case, the relevant measurement quantity can be supplemented or multiple nodes can be processed together.

[0256] In an embodiment of the present disclosure, for the measurement data of the measured quantity on the sensing path, it may be the true measured value, or it may be the result of data compression of the measured value. In this way, when reporting the measurement data, transmission resources can be saved as much as possible.

[0257] In an embodiment of the present disclosure, the measurement data of the first measured quantity on the first sensing path is the measured value of the first measured quantity on the first sensing path;

[0258] Alternatively, if the difference between the measured values of the first measured quantity on the first sensing path and the second sensing path is less than the threshold, the measurement data of the first measured quantity on the first sensing path is the difference between the measured values;

[0259] Among them, the first sensing path is any one of the M sensing paths;

[0260] The second sensing path is the sensing path immediately preceding the first sensing path when the M sensing paths are sorted in descending order of priority.

[0261] It can be understood that in an embodiment of the present disclosure, a data compression method is to report the measured values of all measured quantities on the first sensing path as its measurement data. For the measurement data of the measured quantity on any subsequent sensing path, it is the difference between the measured value of the measured quantity and the measured value of the measured quantity on the previous sensing path. Among them, the measured quantities for which data compression can be performed are TOA / TDOA or Doppler or AOA / DOA and / or RSRP. If the differences between the measured values of the measured quantities required under the current requirements are all within a certain range, it is determined that the measurement data of the measured quantity on the current sensing path is the difference from the measured value of the previous sensing path.

[0262] Exemplarily, the two measured quantities are A and B, and the thresholds for determining whether the reported measurement data is the measured value or the difference between the measured values are A0 and B0 respectively, satisfying |ΔB s | < B0 and / or |ΔA s | < A0, then data compression can be performed before reporting. Among them, ΔA s represents the difference between the measured value of the measured quantity A on the s-th sensing path and the measured value of the measured quantity A on the previous sensing path, and ΔB s represents the difference between the measured value of the measured quantity B on the s-th sensing path and the measured value of the measured quantity B on the previous sensing path;

[0263] Similarly, for the three measured quantities A, B, and C, satisfying |ΔB s | < B0 and |ΔC s | < C0 and / or |ΔA s | < A0; among them, ΔC s represents the difference between the measured value of the measured quantity C on the s-th sensing path and the measured value of the measured quantity C on the previous sensing path.

[0264] Exemplarily, as shown in FIG. 12, the four measured quantities are A, B, C, and D. For the second sensing path, when |ΔB2| < B0, |ΔC2| < C0, and |ΔD2| < D0 are satisfied, the difference in the measured values on the corresponding sensing path is reported, thereby saving the data stream. In addition, as shown in FIG. 13, if |ΔA2| < A0 is also satisfied, ΔA2 can also be reported as measurement data. It should be noted that the data compression path needs to be indicated in the resource info.

[0265] The following describes the technical solutions provided by the embodiments of the present disclosure by way of specific application scenarios.

[0266] In an outdoor drone detection scenario, the sensing node needs to report the speed measurement and ranging data to the sensing entity. According to the sensing requirements, the sensing entity configures a measurement quantity combination of RSRPP / SINRP / RSRPM / SINRM-Doppler-TOA / TDOA for the sensing node and sets the corresponding reporting order (arranging all the measurement quantities of the first m sensing paths with higher priorities in the front). However, during the actual transmission process, the sensing node finds that the available transmission resources are not sufficient to transmit all the measurement data of the measurement quantities at one time. At this time, the sensing node will trigger an intelligent discarding strategy and automatically discard the encoding blocks at the last part corresponding to Sensing-2. The relevant content is as follows:

[0267] 1. Compared with the existing sensing tasks, the sensing entity adds new sensing measurement quantities.

[0268] Specifically, compared with the sensing measurement quantities existing in the protocol, the sensing entity (SF) adds new sensing measurement quantities, where the new sensing measurement quantities include, but are not limited to, Doppler velocity, that is, the speed measurement of the sensing target is added. Compared with the existing RSRP / SINR measurement quantities for communication, RSRPP / SINRP and RSRPM / SINRM are added.

[0269] 2. The sensing entity configures a measurement quantity combination and defines the priorities of different measurement quantities, including but not limited to the following 15 combination forms:

[0270] Ranging requirement: RSRPP / SINRP / RSRPM / SINRM-TOA / TDOA;

[0271] Speed measurement requirement: RSRPP / SINRP / RSRPM / SINRM-Doppler;

[0272] Angle measurement requirement: RSRPP / SINRP / RSRPM / SINRM-AOA / DOA;

[0273] Distance measurement + speed measurement requirements: RSRPP / SINRP / RSRPM / SINRM-TOA / TDOA-Doppler;

[0274] Speed ​​measurement + distance measurement requirements: RSRPP / SINRP / RSRPM / SINRMR-Doppler-TOA / TDOA;

[0275] Distance and angle measurement requirements: RSRPP / SINRP / RSRPM / SINRM-TOA / TDOA-AOA / DOA;

[0276] Angle measurement + distance measurement requirements: RSRPP / SINRP / RSRPM / SINRM-AOA / DOA-TOA / TDOA;

[0277] Speed ​​measurement + angle measurement requirements: RSRPP / SINRP / RSRPM / SINRM-Doppler-AOA / DOA;

[0278] Angle measurement + velocity measurement requirements: RSRPP / SINRP / RSRPM / SINRM-AOA / DOA-Doppler;

[0279] Distance measurement + speed measurement + angle measurement requirements:

[0280] RSRPP / SINRP / RSRPM / SINRM-TOA / TDOA-Doppler-AOA / DOA;

[0281] Distance measurement + angle measurement + speed measurement requirements:

[0282] RSRPP / SINRP / RSRPM / SINRM-TOA / TDOA-AOA / DOA-Doppler;

[0283] Speed ​​measurement + distance measurement + angle measurement requirements:

[0284] RSRPP / SINRP / RSRPM / SINRM-Doppler-TOA / TDOA-AOA / DOA;

[0285] Speed ​​measurement + angle measurement + distance measurement requirements:

[0286] RSRPP / SINRP / RSRPM / SINRM-Doppler-AOA / DOA-TOA / TDOA;

[0287] Angle measurement + distance measurement + speed measurement requirements:

[0288] RSRPP / SINRP / RSRPM / SINRM-AOA / DOA-TOA / TDOA-Doppler;

[0289] Angle measurement + velocity measurement + distance measurement requirements:

[0290] RSRPP / SINRP / RSRPM / SINRM-AOA / DOA-Doppler-TOA / TDOA;

[0291] 3. Based on different sensing needs, the sensing entity defines the priority of different sensing paths, including but not limited to the following rules:

[0292] When ranging is the primary requirement: multiple sensing paths can be sorted according to the RSRP size of different sensing paths, the order of different sensing paths from near to far (focusing on near targets), or the order of different sensing paths from far to near (focusing on far targets);

[0293] When speed measurement is the primary requirement: multiple sensing paths can be sorted according to the size of RSRP of different sensing paths, the speed of different sensing paths from large to small (focusing on moving targets), or the speed of different sensing paths from small to large (focusing on stationary targets);

[0294] When angle measurement is the primary requirement: multiple sensing paths can be sorted in order of RSRP size, angle from smallest to largest, or angle from largest to smallest (depending on the target area).

[0295] Configuration: Speed ​​measurement is the primary requirement, ordered by RSRP size of different sensing paths.

[0296] 4. Sensing nodes report their sensing capabilities:

[0297] Based on its own capabilities, the sensing node reports the combinations of measurements it supports. For example, a sensing node might support the first nine combinations of measurements.

[0298] 5. The sensing entity configures the reporting order of multiple sensing paths / measurements based on the capabilities of the sensing nodes. The sensing entity configures one of the supported measurement combinations reported by the sensing nodes and sets the corresponding measurement data reporting order, which includes the priority of the configured path and the priority of the measurement.

[0299] The sensing entity selects a measurement reporting combination based on the supported measurement combinations reported by the sensing nodes, and configures the corresponding measurement data reporting order for this combination. Specifically, the sensing entity selects the RSRPM-Doppler-TDOA measurement combination and sorts multiple sensing paths according to the size of the first measurement quantity RSRP (i.e., sensing paths with larger first measurement quantity RSRP have higher priority, mainly because sensing paths with larger RSRP have higher confidence; for example, compared to -20dB, 5m / s, the former measurement has higher confidence). The corresponding measurement data reporting order is configured to prioritize the reporting of measurement data from the top three sensing paths with higher priority, as follows:

[0300] Sensing-1 includes: the number of sensing paths in resource info (indicated by 5 bits, up to 32 sensing paths), and prioritizes the measurement data of all measurements of the top 3 sensing paths with higher priority, that is, the measurement data of three measurements are arranged sequentially in each of the top 3 sensing paths.

[0301] Sensing-2 includes measurement data of three measurements of the 4th, 5th, ... sensing paths, arranged sequentially.

[0302] The schematic diagram of the sorting of the measurement data is shown in Figure 14, where A m B m C m These represent the measurement data of the three measurements of the m-th sensing path.

[0303] 6. Intelligent discard strategy:

[0304] In situations where resources are limited, an intelligent discarding strategy is introduced. When the measurement data exceeds the available resources, the system will determine the maximum amount of data to be transmitted based on the pre-set measurement data reporting order, the number of available resource elements (REs), and the configured maximum bitrate, and automatically discard the last part of the encoded block corresponding to Sensing-2.

[0305] After calculation, the maximum amount of data that can be transmitted is the measurement data of 4 sensing paths. Therefore, the measurement data of the remaining 28 sensing paths are discarded, as shown in Figure 15.

[0306] 7. Data Compression Scheme

[0307] For the measurement data of the three measurement quantities A, B, and C on the previous sensing path and the next sensing path, if |ΔB2| < B0 and |ΔC2| < C0 are satisfied, report the differences of the corresponding path measurement quantities, that is, ΔB2 and ΔC2, so as to save the data stream. As shown in FIG. 16, where ΔB2 represents the difference between the measured value of measurement quantity B on the second sensing path and the measured value of measurement quantity B on the first sensing path, and ΔC2 represents the difference between the measured value of measurement quantity C on the second sensing path and the measured value of measurement quantity C on the first sensing path.

[0308] The three measurement quantities are A, B, and C, and the thresholds for determining whether the reported measurement data is a measured value or a difference in measured values are A0, B0, and C0 respectively, and data compression can be performed before reporting.

[0309] 8. The sensing node reports measurement data to the sensing entity:

[0310] The sensing node reports the measurement data to the sensing entity. The sensing node is a base station, and the base station reports the measurement data to the sensing entity.

[0311] Based on the above content, it can be seen that the technical solution provided by the embodiments of the present disclosure mainly has the following advantages:

[0312] Flexibility: By defining different combinations of measurement quantities, this proposal can flexibly configure the combination of measurement quantities according to specific sensing requirements and application scenarios, so as to meet diverse sensing needs;

[0313] Efficiency: Through priority sorting and intelligent discarding strategies, this proposal can preferentially transmit more important sensing data and intelligently discard unimportant data under resource constraints, thereby improving resource utilization and sensing efficiency;

[0314] Accuracy: By defining clear combinations of measurement quantity reports and interaction processes, it ensures accurate understanding and transmission of sensing data between the transceiver parties, thereby improving the accuracy of sensing;

[0315] Scalability: The measurement quantity reporting mechanism has good scalability, and new types of measurement quantities and combination methods can be conveniently added to adapt to the development of future sensing technologies and changes in application requirements.

[0316] The embodiments of the present disclosure provide a sensing entity. FIG. 17 is a schematic structural diagram I of a sensing entity provided by the embodiments of the present disclosure. As shown in FIG. 17, in the embodiments of the present disclosure, the sensing entity includes:

[0317] A configuration module 301, configured to configure N combinations of measurement quantities for the sensing node;

[0318] Where N is a positive integer, different combinations of measurement quantities correspond to different sensing requirements, and each combination of measurement quantities includes one or more measurement quantities.

[0319] In one embodiment of this disclosure, the configuration module 301 is further configured to configure the priority of each measurement quantity included in each measurement quantity combination based on the corresponding sensing requirements.

[0320] In one embodiment of this disclosure, in each combination of measurements, the different measurements are arranged in descending order of priority.

[0321] In one embodiment of this disclosure, each combination of measurements includes one or more of the following measurements:

[0322] Signal quality of the sensing path, signal quality of features on the sensing path, and magnitude of features on the sensing path;

[0323] The features include one or more of the following: time delay, angle, and Doppler velocity.
