Description

A communication method, apparatus and readable storage medium

[0001] This application claims priority to Chinese Patent Application No. 202411588687.5, filed on November 7, 2024, entitled "A Communication Method, Apparatus and Readable Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of wireless communication technology, and in particular to a communication method, apparatus and readable storage medium. Background Technology

[0003] Both wireless communication and wireless sensing are based on electromagnetic wave theory, and electromagnetic wave signals achieve almost seamless coverage in human activities. At the transmitting end, electromagnetic wave signals are modulated, allowing them to carry source information. During propagation, these signals are affected by the wireless environment and also carry environmental information. At the receiving end, by analyzing the electromagnetic wave signals, not only can the carried source information be obtained, but also sensing information reflecting the characteristics of the propagation environment can be extracted. In other words, electromagnetic wave signals have dual functions of communication and sensing, enabling integrated sensing and communication (ISAC). Wireless local area network (WLAN) sensing refers to using wireless signals received from stations (STAs) with WLAN sensing capabilities to determine the characteristics (e.g., speed, angle, attitude) of a target (e.g., pedestrians, animals) in a given environment (e.g., a room, vehicle, business).

[0004] In current communication network architectures, during data transmission, the receiver only verifies the correctness of the encoding and decoding process of the received data and triggers certain retransmission operations. However, in the sensing service scenario of an ISAC network, the accuracy of the transmitted sensing information is equally important. If the accuracy of the sensing data is not verified during transmission to confirm its reliability, it may result in a large amount of invalid transmission, wasting network transmission resources.

[0005] Therefore, improving the accuracy of sensor data transmission and increasing the utilization rate of network transmission resources are urgent problems to be solved. Summary of the Invention

[0006] This application provides a communication method, apparatus, and readable storage medium. During the transmission of sensing data, redundant verification information is added to the transmitted sensing data to determine the accuracy of the current sensing data. This ensures that all received sensing data is reliable, thereby significantly reducing the wireless transmission of sensing data and improving the utilization rate of network transmission resources.

[0007] In a first aspect, a communication method is provided, applied to a first communication device. This method can be executed by a network device. Unless otherwise specified, "network device" in this application can refer to the network device itself, a component within the network device (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the network device. The method includes: the first communication device receiving sensing data of at least one target under test and at least one first redundancy check data, wherein the sensing data of one or more targets under test is associated with one of the at least one first redundancy check data; the first communication device sending a check result corresponding to the sensing data, wherein the check result corresponding to the sensing data is associated with the check result corresponding to the first redundancy check data.

[0008] By implementing the embodiments of this application, the first communication device verifies the sensing data of the target under test based on the received first redundancy verification data, thereby accurately determining the accuracy of the currently transmitted sensing data, ensuring that there is no large amount of wireless transmission, and thus improving the utilization rate of network transmission resources.

[0009] In one alternative implementation, the first communication device acquires second redundancy check data, which is associated with the same sensing target as the first redundancy check data.

[0010] In one optional implementation, if the absolute value of the difference between the first redundant check data and the second redundant check data is less than or equal to a first threshold, the check result of the first redundant check data is considered to be successful; if the absolute value of the difference between the first redundant check data and the second redundant check data is greater than the first threshold, the check result of the first redundant check data is considered to be unsuccessful; or, if the ratio of the first redundant check data to the second redundant check data is within a first range, the check result of the first redundant check data is considered to be successful; if the ratio of the first redundant check data to the second redundant check data is not within the first range, the check result of the first redundant check data is considered to be unsuccessful.

[0011] In one optional implementation, the number of first redundant verification data that failed verification is counted. If the number is less than or equal to a second threshold, the verification result corresponding to the perceived data is determined to be verified successfully. If the number is greater than the second threshold, the verification result corresponding to the perceived data is determined to be verified unsuccessfully. Alternatively, the number of first redundant verification data that failed verification is counted. If the ratio of the number of first redundant verification data to the total number of first redundant verification data is less than or equal to a third threshold, the verification result corresponding to the perceived data is determined to be verified successfully. If the ratio of the number of first redundant verification data to the total number of first redundant verification data is greater than the third threshold, the verification result corresponding to the perceived data is determined to be verified unsuccessfully.

[0012] In one alternative implementation, the sensing data includes the scatterer information (SIE) of the target under test, and the first redundancy check data includes the SIE of the anchor point, where the anchor point is a sensing target with known information.

[0013] In one optional implementation, when the amount of perceived data M is less than or equal to the fourth threshold T, the value of the first redundancy check data is x; when M is greater than T, the value of the first redundancy check data is y, where M is a positive integer greater than 1, x and y are fixed values ​​greater than 1, and the value of x is less than the value of y; or, when the ratio of the amount of perceived data to the amount of first redundancy check data is a fixed value η, the value of the first redundancy check data is the integer value of M divided by η and rounded up or the integer value of M divided by η and rounded down.

[0014] In one optional implementation, the data length of the sensing data, the data length of the first redundancy check data, and the data length of the sensing information block (SIB) are obtained. If the sum of the data lengths of the sensing data and the first redundancy check data is less than or equal to the data length of the SIB, the number of SIBs is determined to be 1. If the sum of the data lengths of the sensing data and the first redundancy check data is greater than the data length of the SIB, the difference between the data length of the SIB and the data length of the first redundancy check data is calculated, and the number of SIBs is determined to be the value of the sensing data length divided by the difference and rounded up.

[0015] In one alternative implementation, the first communication device receives transmission indication information, which indicates whether the currently received sensing data is the same as the previously received sensing data.

[0016] In one optional implementation, the transmission indication information includes an indication flag bit, which occupies 1 bit. The indication flag bit is compared with the previously received indication flag bit. If the value of the indication flag bit is the same as the previously received indication flag bit value, the current sensing data is determined to be a retransmission. If the value of the indication flag bit is different from the previously received indication flag bit value, the current sensing data is determined to be an initial transmission. Alternatively, the value of the indication flag bit is determined. If the value of the indication flag bit is a first value, the current sensing data is determined to be an initial transmission. If the value of the indication flag bit is a second value, the current sensing data is determined to be a retransmission.

[0017] Secondly, a communication method is provided, which is applied to a second communication device. This method can be executed by a terminal device. Unless otherwise specified, "terminal device" in this application can refer to the terminal device itself, or a component in the terminal device (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the terminal device. The method includes: sending at least one sensing data of a target under test and at least one first redundancy check data, wherein the sensing data of one or more targets under test is associated with one of the at least one first redundancy check data; receiving a check result corresponding to the sensing data, wherein the check result corresponding to the sensing data is associated with the check result corresponding to the first redundancy check data.

[0018] In one alternative implementation, the sensing data includes the scatterer information (SIE) of the target under test, and the first redundancy check data includes the SIE of the anchor point, where the anchor point is a sensing target with known information.

[0019] In one optional implementation, when the amount of perceived data M is less than or equal to a first threshold T, the value of the first redundancy check data is x; when M is greater than T, the value of the first redundancy check data is y, where M is a positive integer greater than 1, and x and y are fixed values ​​greater than 1, with the value of x being less than the value of y; or, when the ratio of the amount of perceived data to the amount of first redundancy check data is a fixed value η, the value of the first redundancy check data is the integer value of M divided by η and rounded up or the integer value of M divided by η and rounded down.

[0020] In one optional implementation, the data length of the sensing data, the data length of the first redundancy check data, and the data length of the sensing information block (SIB) are obtained. If the sum of the data lengths of the sensing data and the first redundancy check data is less than or equal to the data length of the SIB, the number of SIBs is determined to be 1. If the sum of the data lengths of the sensing data and the first redundancy check data is greater than the data length of the SIB, the difference between the data length of the SIB and the data length of the first redundancy check data is calculated, and the number of SIBs is determined to be the value of the sensing data length divided by the difference and rounded up.

[0021] In one alternative implementation, transmission indication information is sent to indicate whether the currently received sensing data is the same as the previously received sensing data.

[0022] In one optional implementation, the transmission indication information includes an indication flag bit, which occupies 1 bit. If the verification result is a verification failure, the value of the indication flag bit remains unchanged, and the sensing data is retransmitted. If the verification result is a verification success, the value of the indication flag bit is flipped, and new sensing data is retransmitted. Alternatively, if the verification result is a verification failure, the value of the indication flag bit is set to a second value, and the sensing data is retransmitted. If the verification result is a verification success, the value of the indication flag bit is set to a first value, and new sensing data is retransmitted.

[0023] Thirdly, a communication device is provided. This communication device can be a first communication device, or a module or unit (e.g., a chip, chip system, or circuit) within the first communication device that performs each of the methods / operations / steps / actions described in the first aspect, or a device compatible with the first communication device.

[0031] The communication unit is also used to receive the verification result corresponding to the sensing data, and the verification result corresponding to the sensing data is associated with the verification result corresponding to the first redundant verification data.

[0032] In addition, other alternative implementations of the communication device in this regard can be found in the relevant content of the second aspect above, and will not be described in detail here.

[0033] As an example, the communication unit can be a transceiver or a communication interface, the storage unit can be a memory, and the processing unit can be a processor. The processor is coupled to the memory, which stores programs or instructions for the processor. The processor can be used to cause the communication device to perform the method described in the first aspect above when the program or instructions are executed by the processor. The transceiver or communication interface can be used to send and receive signals and / or data.

[0034] In one embodiment, a transceiver is configured to receive sensing data of at least one target under test and at least one first redundancy check data, wherein the sensing data of one or more targets under test is associated with one of the at least one first redundancy check data.

[0037] In addition, other alternative implementations of the communication device in this regard can be found in the relevant content of the first aspect above, and will not be described in detail here.

[0038] In one embodiment, a transceiver is configured to transmit sensing data of at least one target under test and at least one first redundancy check data, wherein the sensing data of one or more targets under test is associated with one of the at least one first redundancy check data.

[0045] Unless otherwise specified, or unless it contradicts its actual function or internal logic in the relevant description, the transmission and reception operations involved by the processor can be more generally understood as processor output and reception, input and other operations, rather than transmission and reception operations directly performed by radio frequency circuits and antennas.

The memory can be a non-transitory memory, such as read-only memory (ROM), which can be integrated with the processor on the same chip or disposed on different chips.

In this application's embodiments, the chip system can be composed of chips, or it can include chips and other discrete devices. The embodiments of this application do not limit the specific technology or device form used in the terminal device.

[0081] It is understood that when the network device is an access point (as shown in Figure 1, 110b) and the terminal device is a non-access point site (as shown in Figure 1, 120f or 120g), the network formed by the network device and the terminal device can be a wireless local area network (WLAN). In other words, the communication system shown in Figure 1 can include, but is not limited to, WLAN.

[0082] For example, refer to Figure 2, which is a schematic diagram of another communication system provided in an embodiment of this application. As shown in Figure 2, the communication system includes network devices and terminal devices. The terminal devices and network devices can communicate with each other. The number and configuration of devices shown in Figure 2 are for illustrative purposes only and do not constitute a limitation on the embodiments of this application. In practical applications, it may include two or more terminal devices and two or more network devices. In Figure 2, the terminal device is a mobile phone, and the network device is a base station.

[0083] It is understood that although this application uses a network deploying the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard as an example, those skilled in the art will readily understand that the various aspects of this application can be extended to other networks employing various standards or protocols, such as Bluetooth, high-performance radio LAN (HIPERLAN) (a wireless standard similar to IEEE 802.11), wide area networks (WANs), personal area networks (PANs), or other networks now known or to be developed in the future. Therefore, regardless of the coverage area and wireless access protocol used, the various aspects provided in this application can be applied to any suitable wireless network.

[0084] Secondly, some terms and related technologies involved in the embodiments of this application will be explained to facilitate understanding by those skilled in the art.

[0085] 1. Sensor-Integrated Computing (ISAC)

[0086] Both wireless communication and wireless sensing are based on electromagnetic wave theory. At the transmitting end, electromagnetic wave signals are modulated, allowing them to carry source information. During propagation, these signals are affected by the wireless environment, meaning they are modulated by the environment and thus also carry environmental information. At the receiving end, by analyzing the electromagnetic wave signals, not only can the carried source information be obtained, but also sensing information reflecting the characteristics of the propagation environment can be extracted. In other words, electromagnetic wave signals inherently possess both communication and sensing functions, making integrated sensing and communication systems possible. Compared to systems where sensing and communication are separate, integrated sensing and communication systems offer many advantages, such as cost savings, reduced equipment size, lower power consumption, and improved spectral efficiency. The communication performance indicators for integrated sensing and communication services mainly include bit error rate (BER), network coverage, latency, data rate, spectral efficiency, and reliability. Sensing performance indicators include detection accuracy, positioning accuracy, speed accuracy, and distance accuracy. Specific sensing implementation methods include single-base sensing (such as base station self-transmission and self-reception, terminal self-transmission and self-reception) and dual-base sensing (such as base station A transmitting and base station B receiving, base station transmitting and terminal receiving, terminal transmitting and base station receiving, etc.). Single-base sensing is executed by a single node, similar to traditional single-base radar. Since the transmitter and receiver are in the same location, the sensing signal does not need to be a dedicated pilot signal; communication signals carrying data can also be used for single-base sensing. Furthermore, the sensing result can be directly parsed by this node without additional data transmission or external equipment assistance. However, single-base mode requires the base station or terminal to have full-duplex capability. Dual-base sensing involves one base station or terminal transmitting a sensing signal, and another base station or terminal receiving the sensing signal for sensing. This method is similar to the working mode of traditional dual-base radar. Due to the spatial separation of the transmitter and receiver, this mode does not require the transceiver to have full-duplex capability. However, this mode requires dedicated sensing signals, and the positional and synchronization errors of the transmitter and receiver will also affect the sensing result.

[0087] 1. Hybrid Automatic Repeat Request (HARQ)

[0088] HARQ is a technique that combines forward error correction code (FEC) and automatic repeat request (ARQ). The basic principle of HARQ is that the receiver uses FEC to correct the correctable errors, identifies uncorrectable data packets through error detection, discards these packets, and requests the transmitter to retransmit the same data packet. Common automatic repeat request protocols are stop-and-wait protocols, where the transmitter pauses before sending a data packet, waiting for acknowledgment from the receiver. When a data packet arrives at the receiver, it is checked for errors. If the reception is correct, an acknowledgment (ACK) signal is returned; otherwise, a non-acknowledgment (NACK) signal is returned. Upon receiving an ACK signal, the transmitter sends new data; otherwise, it retransmits the previously transmitted data packet. During the waiting period for acknowledgment, the channel is idle and no data is transmitted. This method is simple to implement, has low signaling overhead, and requires less buffer capacity at the receiver because both the transmitter and receiver operate on only the same data packet at any given time.

[0089] With the continuous development of integrated sensing, point cloud acquisition models based on radio frequency signals have gradually attracted attention. In single-base sensing, extracting point clouds from raw echoes for environmental perception is one of the main technologies currently used. However, single-base sensing often suffers from problems such as short sensing distance and limited field of view. To increase the sensing distance and field of view, a preferred approach is to use multi-station fusion to address these drawbacks. Referring to Figure 3, which is a schematic diagram of a multi-station data fusion process and data format provided in an embodiment of this application, the station information includes scattering point 1, scattering point 2, ..., scattering point N, etc. A scattering point refers to the object to be measured in the sensing scene, which can reflect radio frequency signals. For each station, it includes multiple sensing parameters (i.e., sensing data), such as sensing link identifier, transmitting identifier (TX ID), receiving identifier (RX ID), time, direction, configuration information, or capabilities. For example, for scattering point 1, its corresponding sensing data includes scatterer ID, coordinates (x, y, z), angle, log-likelihood ratio, power, signal-to-noise ratio (SNR), velocity, and scatterer type. In the multi-station fusion process, circles of different colors represent scattering points from different sources, such as scattering points from different nodes. Then, the point clouds of scattering points from multiple different sources are merged and fused.

[0090] It's understandable that multi-site fusion effectively expands the sensing field of view and increases the sensing distance. However, during the transmission of fused sensing data, the accuracy of the data is not verified, meaning the accuracy and reliability of the transmitted data cannot be guaranteed. This can lead to a large amount of inaccurate sensing data being sent and received, resulting in significant invalid transmissions. This greatly increases transmission overhead, wastes transmission resources, and reduces resource utilization. Furthermore, because the accuracy of sensing data is not verified during transmission, there is a lack of explanation and clarification regarding the retransmission process for failed sensing data.

[0091] Based on the above, this application provides a communication method, device, and readable storage medium to address the problem of large-scale wireless transmission of sensing data in existing systems. This method can verify the sensing accuracy of sensing data during transmission, reduce invalid transmission of sensing data, save network transmission resources, and improve the utilization rate of network transmission resources.

[0092] The technical solution provided in this application will be described in detail below with reference to more accompanying drawings.

[0093] To facilitate a clear description of the technical solutions of this application, multiple embodiments are used for illustration, as detailed in the following descriptions of the various embodiments.

It is understood that the order of the embodiments below does not represent their importance.

[0094] It should be understood that in this application, the indication includes direct indication (also known as explicit indication) and implicit indication. Direct indication information A refers to information A being included; implicit indication information A refers to information A being indicated through the correspondence between information A and information B, and through direct indication information B. The correspondence between information A and information B can be predefined, pre-stored, pre-burned, or pre-configured.

[0095] It should be understood that in this application, information D is determined based on information C, which includes both situations where information D is determined solely based on information C and situations where information D is determined based on information C and other information. Furthermore, the use of information C to determine information D can also include indirect determination, such as when information D is determined based on information E, and information E is determined based on information C.

[0096] Furthermore, in the embodiments of this application, "network element A sends information A to network element B" can be understood as network element B being the destination of information A or an intermediate network element in the transmission path between the destination and network element B, which may include sending information directly or indirectly to network element B. "Network element B receives information A from network element A" can be understood as network element A being the source of information A or an intermediate network element in the transmission path between the source and network element A, which may include receiving information directly or indirectly from network element A.

Similar expressions in this application can be understood in a similar way and will not be elaborated further here.

[0097] Please refer to Figure 4, which is a flowchart illustrating a communication method provided in an embodiment of this application. The method includes, but is not limited to, the following steps:

[0098] S401: The first communication device receives sensing data of at least one target under test and at least one first redundancy check data sent by the second communication device.

[0099] Specifically, the first communication device can be a base station in the RAN, and the second communication device can be a UE. For ease of description, this will not be further explained later. The second communication device first needs to access the network, and the process of accessing the network is the process of establishing an RRC connection.

[0100] For example, the second communication device first sends a random access preamble. After receiving the random access preamble, the first communication device sends a random access response message. Then, the second communication device sends an RRC connection request. After resolving the conflict, the first communication device returns an RRC connection establishment success message. It should be understood that after the RRC connection is established, wireless network signaling can be transmitted, such as allocating wireless resources.

[0101] In addition, in the integrated sensing scenario, the second communication device also needs to send at least one sensing data of the target under test and at least one first redundancy verification data to the first communication device.

[0102] Specifically, the second communication device needs to simultaneously measure the target and anchor points in the application scenario. Anchor points refer to artificially deployed, known sensing target objects in the measurement scenario. The known information can include the anchor point's location, velocity, target type, etc. The number of anchor points can be set according to actual needs, and this application does not limit this. The target can include passive objects, such as buildings, urban facilities (billboards, bridges, etc.), traffic conditions (vehicles, pedestrians, etc.), or active objects, such as mobile phones, IoT devices, and smart cars. After measuring the target and anchor points, the second communication device can acquire the corresponding sensing data, and then send the acquired multiple sensing data points to the first communication device.

[0103] It should be understood that the information of the anchor points is known, while the perceived data of the target to be measured is unknown. The anchor points with known information can be used to assist in verifying the accuracy of the perceived data of the target to be measured. That is, the second communication device will use the measurement results of the anchor points as the first redundant verification data and send it together with the perceived data of the target to be measured to the first communication device so that the first communication device can verify the accuracy of the perceived data of the target to be measured.

[0104] For example, please refer to Figure 5, which is a schematic diagram of a perception measurement scenario provided by an embodiment of this application. As shown in Figure 5, the base station simultaneously performs perception measurements on multiple targets to be measured (vehicles in Figure 5) and anchor points, and can obtain perception data of the targets to be measured and perception data of the anchor points. Then, the base station sends the measurement results to the UE. The UE can verify the accuracy of the perception data of the targets to be measured based on the received perception data of the targets to be measured and perception data of the anchor points, thereby determining whether the measurement results sent by the base station are reliable.

[0105] Furthermore, after acquiring the sensing data of the target under test and the anchor point, the second communication device needs to encapsulate and process them. First, the information of each scattering point is stored using a Sensor Internet Explorer (SIE). The SIEs of the target under test form the original sensing transport block (STB), and the SIEs of the anchor point form the sensing redundancy check (SRC). The SRC is used to perform sensing verification on the original STB.

[0106] It should be noted that the source of SIE in SRC can be the perception information of anchor points measured in the same measurement scenario or the perception information of anchor points measured in different measurement scenarios. This application does not limit this.

[0107] Optionally, if the sum of the original STB data length and the SRC data length is less than or equal to the maximum information block length specified by the low-density parity-check (LDPC) code, then no splitting is required, meaning that a single LDPC code can be used to transmit all the SIEs of the target under test and the SIEs of the anchor points that need to be sent. If the sum of the original STB data length and the SRC data length is greater than the maximum information block length specified by the LDPC code, then it needs to be split into multiple sensing information blocks (SIBs), and then an SRC is added for each SIB.

[0108] For example, refer to Figure 6, which is a schematic diagram of a data block to be transmitted provided in an embodiment of this application. As shown in Figure 6, the original sensing transmission block (STB) contains multiple target information elements (SIEs) of the target to be tested, and the sensing redundancy check block (SRC) contains multiple anchor point SIEs. After adding the SRC, the original STB becomes the STB to be processed. When the data length of the STB to be processed exceeds the maximum information block length of the LDPC code, the STB to be processed is split into multiple information blocks (SIBs). Then, an SRC is added after each SIB. Each SIB with an added SRC constitutes the STB to be transmitted. Refer to Figure 7, which is a schematic diagram of a data block structure to be transmitted provided in an embodiment of this application. As shown in Figure 7, a certain amount of redundant information is added to the original sensing transmission block, and it is split into SIB blocks, ultimately forming the STB to be transmitted. The STB to be transmitted contains W data SIBs, each data SIB has an SRC added after it, each data SIB contains M target information elements (SIEs) of the target to be tested, and the SRC corresponding to each data SIB contains N anchor point SIEs.

[0109] It is worth noting that the data length (i.e., the number of bits) of the SIE is not uniformly fixed. The value of the number of bits K can range from 16 bits to 1024 bits, and its specific value depends on the integrity of the transmission of each physical quantity shown in Figure 3. Furthermore, for multiple SIEs within each SIB, their format and data length can be the same or different. Similarly, for multiple SIEs within the same SRC, their format and data length can be the same or different.

[0110] In one optional implementation, when the amount of perceived data M is less than or equal to the fourth threshold T, the value of the first redundancy check data is x; when the amount of perceived data M is greater than the fourth threshold, the value of the first redundancy check data is y, where M is a positive integer greater than 1, x and y are fixed values ​​greater than 1, and the value of x is less than the value of y; or, when the ratio of the amount of perceived data to the amount of first redundancy check data is a fixed value η, the value of the first redundancy check data is the integer value of M divided by η and rounded up or the integer value of M divided by η and rounded down.

[0111] Specifically, by adding redundant data appropriately, the verification efficiency can be improved while ensuring the verification results. That is, when the amount of perceived data is small, only a small amount of redundancy needs to be added to complete the verification. When the amount of perceived data is large, more redundancy needs to be added to verify the accuracy of perception, thereby ensuring the verification results.

[0112] Furthermore, the value of the first redundancy check data can be determined in two ways. In the first method, the value of the first redundancy check data is a fixed value. First, the number M of SIEs contained in a SIB is determined, and then it is compared with a pre-set fourth threshold. When M is less than or equal to the fourth threshold T, it indicates that the amount of sensing data is small, and the number of SIEs in the added SRC is x. When M is greater than the fourth threshold T, it indicates that the amount of sensing data is large, and the number of SIEs in the added SRC is y. T can be set according to actual needs, and x and y can also be set as needed. This application does not limit this. For example, T can be set to 16, x can be set to 4, and y can be set to 8. In the second approach, the value of the first redundancy check data is a floating value, not a fixed value, but varies depending on the amount of sensing data. First, the ratio of the number of SIEs M contained in the SIB to the number of SIEs contained in the first redundancy check data is set to a fixed value η. Then, the number of SIEs M contained in an SIB is determined. The value of M divided by η and rounded up is the number of SIEs in the added SRC, or the value of M divided by η and rounded down is the number of SIEs in the added SRC. η can be set according to actual needs, for example, it can be set to 16, but this application does not limit it.

[0113] It is understandable that redundant data can be flexibly determined and added in various ways for each SIB, which can improve verification efficiency while ensuring the verification results.

[0114] In one optional implementation, the data length of the sensing data, the data length of the first redundancy check data, and the data length of the SIB are determined. When the sum of the data length of the sensing data and the data length of the first redundancy check data is less than or equal to the data length of the SIB, the number of SIBs is determined to be 1. If the sum of the data length of the sensing data and the data length of the first redundancy check data is greater than the data length of the SIB, the difference between the data length of the SIB and the data length of the first redundancy check data is calculated, and the number of SIBs is determined to be the value of the sensing data length divided by the difference and rounded up.

[0115] Specifically, the data length of the SIB (Sensory Information Block) can be understood as the maximum information block length K of the LDPC code. cb When the length of the STB (i.e., sensing data and first redundancy check data) to be transmitted is less than or equal to K cb If the number of SIBs is greater than K, then no splitting is required, and the number of SIBs is 1. cb In this case, it needs to be split, first calculating K. cb The difference between the first redundancy check data (i.e., SRC) and the number of SIBs obtained from the split is then determined by dividing the length of the STB to be transmitted by this difference and rounding it up. Optionally, K cb The value of K may vary depending on the LDPC code. For example, in LDPC BG1, K... cb The value is 8848. In LDPC BG2, K cb The value is 3840.

[0116] S402: The first communication device sends the verification result corresponding to the sensing data to the second communication device.

[0117] Specifically, after receiving the sensing data and the first redundancy verification data sent by the second communication device, the first communication device needs to verify the accuracy of the sensing data, obtain the verification result, and then return the result to the second communication device.

[0118] In one alternative implementation, the first communication device acquires second redundancy check data, which is associated with the same sensing target as the first redundancy check data.

[0119] Specifically, the first communication device pre-stores the true scattering ground-truth (SGT) information of the anchor points. The SGT is the second redundancy check data, and the physical quantities contained therein are the same as those contained in the measured SIE of the anchor points. In other words, the SGT contains all known information about all anchor points. The first communication device can compare each SIE information value in the SRC with the corresponding anchor point true value, and determine the accuracy of the received sensing data based on the comparison result.

[0120] For example, referring to Figure 8, which is a schematic diagram of a perceptual redundancy verification provided in an embodiment of this application. As shown in Figure 8, the second communication device sends a data SIB composed of multiple SIEs of the targets to be tested and a redundant SRC composed of the SIEs of the anchor points to the first communication device. The first communication device stores the SGT of the anchor points, which contains the SIEs of all anchor points. The first communication device compares the SIEs in the redundant SRC with the SIEs in the SGT one by one, so as to determine whether the SIEs in the data SIB are accurate based on the comparison results.

[0121] In one optional implementation, if the absolute value of the difference between the first redundant check data and the second redundant check data is less than or equal to a first threshold, the check result of the first redundant check data is considered to be verified as passed; if the absolute value of the difference between the first redundant check data and the second redundant check data is greater than the first threshold, the check result of the first redundant check data is considered to be verified as failed. Alternatively, if the ratio of the first redundant check data to the second redundant check data is within a first range, the check result of the first redundant check data is considered to be verified as passed; if the ratio of the first redundant check data to the second redundant check data is not within the first range, the check result of the first redundant check data is considered to be verified as failed.

[0122] Specifically, for each received SIB, the first communication device extracts and parses the SRC to obtain the sensing information of the N anchor points contained therein. Then, based on the anchor point identifier (ID), it finds the measured SIE and the real SIE of the same anchor point, and compares them to obtain the error. If the error exceeds the threshold, the SIE sensing is considered to have failed; otherwise, the SIE sensing is considered to have succeeded.

[0123] Furthermore, verification can be performed in two ways. In the first verification method, the absolute value of the difference between the measured value and the true value is directly calculated and compared with a first threshold. If it is less than or equal to the first threshold, the SIE sensing is considered successful and the verification passes; if it is greater than the first threshold, the SIE sensing is considered unsuccessful and the verification fails. The first threshold can be set according to actual needs, and this application does not impose any limitations on it. In the second method, the ratio of the measured value to the true value is directly calculated and determined whether it falls within a first range. If it is within the first range, the SIE sensing is considered successful and the verification passes; if it is not within the first range, the SIE sensing is considered unsuccessful and the verification fails. The first range can be set according to actual needs, and this application does not impose any limitations on it.

[0124] In one optional implementation, the number of first redundant verification data that failed verification is counted. If the number is less than or equal to a second threshold, the verification result corresponding to the perceived data is determined to be verified successfully. If the number is greater than the second threshold, the verification result corresponding to the perceived data is determined to be verified failed. Alternatively, the number of first redundant verification data that failed verification is counted. If the ratio of the number of first redundant verification data to the total number of first redundant verification data is less than or equal to a third threshold, the verification result corresponding to the perceived data is determined to be verified successfully. If the ratio of the number of first redundant verification data to the total number of first redundant verification data is greater than the third threshold, the verification result corresponding to the perceived data is determined to be verified failed.

[0125] Specifically, after completing the determination of each SIE, the first communication device can determine the accuracy of the data SIB transmitted in this transaction.

[0126] Optionally, the number of SIEs that fail verification in the SRC can be counted. If the number is less than or equal to the second threshold, the transmission is considered successful, the SIB of the transmitted data is determined to be accurate, the verification passes, and it is recorded as S-ACK. Otherwise, the transmission is considered to have failed, the SIB of the transmitted data is determined to be inaccurate, the verification fails, and it is recorded as S-NACK. The second threshold can be set according to actual needs, and this application does not limit it.

[0127] Optionally, the number of SIEs that failed verification in the SRC is counted, and the ratio of this number to the total number of SIEs in the SRC is calculated. If the ratio is less than or equal to the third threshold, the transmission is considered successful, the SIB of the transmitted data is determined to be accurate, the verification passes, and it is recorded as S-ACK. Otherwise, the transmission is considered to have failed, the SIB of the transmitted data is determined to be inaccurate, the verification fails, and it is recorded as S-NACK. The third threshold can be set according to actual needs, and this application does not limit it.

[0128] In one optional implementation, the first communication device receives transmission indication information sent by the second communication device, the transmission indication information being used to indicate whether the currently received sensing data is the same as the previously received sensing data.

[0129] Specifically, for sensing data that fails to be verified, the second communication device needs to retransmit it. Therefore, the second communication device needs to add transmission indication information each time it transmits. This transmission indication information is used to indicate whether the sensing data being transmitted is the initial sensing data or the retransmitted sensing data.

[0130] Furthermore, the transmission indication information includes a sensing new data indicator (S-NDI) bit, which occupies 1 bit. After receiving the sensing new data indicator, the first communication device compares it with the previously received sensing new data indicator. If the value of the sensing new data indicator is the same as the previously received value, it determines that the currently received sensing data is the initial sensing data. If the value of the sensing new data indicator is different from the previously received value, it determines that the currently received sensing data is the retransmitted sensing data. Alternatively, the value of the sensing new data indicator is determined. If the value of the sensing new data indicator is a first value, it determines that the currently received sensing data is the initial sensing data. If the value of the sensing new data indicator is a second value, it determines that the currently received sensing data is the retransmitted sensing data.

[0131] As can be seen, since the indicator flag only occupies 1 bit, its value can only be 0 or 1. Under the S-NDI flipping mechanism, if the current transmitted sensing data is the initial sensing data, the S-NDI value is flipped, for example, changing 0 to 1 or 1 to 0. If the current transmitted sensing data is retransmitted sensing data, the S-NDI value remains unchanged; that is, if the previous value was 0, the value remains 0, and if the previous value was 1, the value remains 1. Under the S-NDI fixed value mechanism, if the current transmitted sensing data is the initial sensing data, the S-NDI value is fixed at 0 (or 1); if the current transmitted sensing data is retransmitted sensing data, the S-NDI value is fixed at 0 (or 0).

[0132] For example, please refer to Figure 9, which is a comparative schematic diagram of initial transmission / retransmission provided by an embodiment of this application. As shown in Figure 9, under the S-NDI flipping mechanism, the second communication device first transmits STB1 initially, with the corresponding S-NDI being 0. The first communication device verifies STB1. When the verification fails, it returns S-NACK to the second communication device. After receiving the S-NACK, the second communication device retransmits STB1 again. At this time, the corresponding S-NDI is still 0. The first communication device verifies STB1 again. When the verification passes, it returns S-ACK to the second communication device. After receiving the S-ACK, the second communication device continues to transmit new sensing data, that is, initially transmit STB2, with the corresponding S-NDI being 0. Similarly, under the fixed S-NDI value mechanism, the second communication device first transmits STB1 initially, with the corresponding S-NDI being 0. The first communication device verifies STB1. When the verification fails, it returns S-NACK to the second communication device. After receiving the S-NACK, the second communication device retransmits STB1 again, this time with the corresponding S-NDI being 1. The first communication device verifies STB1 again. When the verification passes, it returns S-ACK to the second communication device. After receiving the S-ACK, the second communication device continues to transmit new sensing data, i.e., transmits STB2 initially, with the corresponding S-NDI being 0.

[0133] It should be noted that the Sensing Hybrid Automatic Repeat Request (S-HARQ) in this embodiment differs from and is related to HARQ in the prior art. Refer to Figure 10, which is a schematic diagram of the relationship between S-HARQ and HARQ provided in this embodiment. As shown in Figure 10, HARQ is responsible for retransmitting decoding errors, ensuring that the data to be transmitted remains accurate and arrives at the receiver after encoding and decoding. S-HARQ, on the other hand, is responsible for retransmitting inaccurate sensing measurements, ensuring that the received sensing data has the accuracy and reliability of the sensing measurement results. If the accuracy of the sensing results contained in the data is doubted (e.g., the sensing precision is too poor or the sensing error is too large), a new sensing measurement is requested, and the measurement result is retransmitted.

[0134] In addition, this application embodiment designs a signaling allowedSHARQ-mode belonging to higher layers (e.g., RRC layer and MAC layer) for logical channel control of S-HARQ. In the RRC layer, the allowedSHARQ-mode is set to indicate whether the S-HARQ mode is allowed to be enabled when the logical channel is mapped. In the MAC layer, if the allowedSHARQ-mode of the current logical channel is found to be configured, then a logical channel (which can be uplink, downlink, sidelink, etc.) that meets the following conditions is selected for the authorization of a transmission link. The logical channel includes the S-HARQ mode allowed by the S-HARQ process associated with the link.

[0135] In summary, this communication method adds redundant verification information to the transmitted sensing data during the transmission process to determine the accuracy of the currently transmitted sensing data. This ensures that the received sensing data is accurate and reliable, thereby significantly reducing the wireless transmission of sensing data and improving the utilization rate of network transmission resources.

For example, each function can be divided into its own functional modules, or two or more functions can be integrated into one processing module. The integrated modules can be implemented in hardware or as software functional modules. It should be noted that the module division in this application is illustrative and only represents one logical functional division; other division methods may be used in actual implementation.

The communication device 300 can be a first communication device or a second communication device, and can also be a component of the first communication device (e.g., an integrated circuit, a chip, etc.) or a component of the second communication device (e.g., an integrated circuit, a chip, etc.).

The communication device 300 may include a processing unit 310. Optionally, the communication device 300 may further include a communication unit 320, where the processing unit 310 controls the communication unit 320 to perform data / signaling transmission and reception.
