[0004] Future Beyond 5G (B5G) and 6G wireless communication systems are expected to provide a variety of high-precision sensing services, such as indoor positioning for robot navigation, Wi-Fi sensing for smart homes, and radar sensing for autonomous vehicles. Sensing and communication systems are typically designed separately and occupy different frequency bands. Integrated Sensing and Communication (ISAC) enables sensing and communication systems to share the same frequency band and hardware, improving frequency efficiency and reducing hardware costs. ISAC will become a key technology for future wireless communication systems, supporting many important application scenarios. Typical applications of ISAC include navigation and obstacle avoidance for autonomous vehicles, indoor positioning and activity recognition based on Wi-Fi, communication and sensing for unmanned aerial vehicles, extended reality (XR), and radar and communication integration. Each application has different requirements, limitations, and regulatory issues. ISAC has attracted significant research interest and attention from both academia and industry.

[0044] The following is a brief description of the technical content involved in this application.

[0045] 1. Communication and perception integration / synaesthesia integration:

[0046] Integrated Sensing and Communication (ISAC) achieves low-cost integration of both communication and perception functions through shared hardware and software-defined functionality. Its key features include: a unified and simplified architecture; reconfigurable and scalable functionality; and improved efficiency and reduced costs. The advantages of ISAC are threefold: reduced equipment cost and size; improved spectrum utilization; and enhanced system performance.

[0047] At present, typical communication perception integration scenarios that are expected to be achieved through technical upgrades based on the 5G communication system architecture are shown in Table 1.

[0048] Table 1 Typical scenarios of communication perception integration

[0049] There are six basic sensing modes, depending on the difference between the sending and receiving nodes of the sensing signal, as shown in Figure 2:

[0050] (1) Base station self-transmitting and self-receiving sensing: In this sensing mode, base station A sends a sensing signal and performs sensing measurement by receiving the echo of the sensing signal.

[0051] (2) Inter-base station air interface sensing: Base station B receives the sensing signal sent by base station A and performs sensing measurements.

[0052] (3) Uplink air interface perception: Base station A receives the perception signal sent by terminal A and performs perception measurement.

[0053] (4) Downlink air interface perception: Terminal B receives the perception signal sent by base station B and performs perception measurement.

[0054] (5) Terminal self-transmitting and self-receiving perception: Terminal A sends a perception signal and performs perception measurement by receiving the echo of the perception signal.

[0055] (6) Sidelink perception between terminals: Terminal B receives the perception signal sent by terminal A and performs perception measurements.

[0056] It's worth noting that each sensing method in Figure 2 uses one sensing signal transmitting node and one sensing signal receiving node as examples. In actual systems, one or more sensing methods can be selected based on different sensing use cases and requirements, and each sensing method can have one or more transmitting and receiving nodes. The sensing targets in Figure 2 use people and vehicles as examples, assuming neither person nor vehicle carries or has installed signal transceiver / receiver equipment. In actual scenarios, the range of sensing targets will be much richer.

[0057] 2. Perception of Line of Sight (LOS) and Non-Line of Sight (NLOS)

[0058] In communications, LOS and NLOS are defined based on the line-of-sight between the transmitter and receiver. In perception, LOS and NLOS are determined based on whether there is any obstruction between the sensor (sender or receiver) and the target. If there is obstruction, it is considered NLOS; if there is no obstruction, it is considered LOS.

[0059] The following describes LOS and NLOS in the single-station sensing mode and the dual-station sensing mode.

[0060] 1) In single-station sensing mode, based on channel reciprocity, the path from the sensing sender to the sensing target and the path from the sensing target to the sensing receiver can be considered to have the same LOS probability. There are two cases, as shown in Figure 3.

[0061] 2) In the dual-station sensing mode, the LOS probabilities of the path from the sensing sender to the sensing target and the path from the sensing target to the sensing receiver are different and need to be calculated separately. There are four cases as shown in Figure 4.

[0062] The following, in combination with the accompanying drawings, describes in detail the transmission method, request method, terminal and network-side device of the perception-assisted data provided by the embodiments of the present application through some embodiments and their application scenarios.

[0063] Referring to FIG. 5 , an embodiment of the present application provides a method for transmitting perception assistance data, including:

[0064] Step S11: The terminal receives a first message sent by a network-side device, where the first message is used to request perception assistance data, where the perception assistance data is used to assist the network-side device in perception, and the perception assistance data includes at least one of perception calculation assistance data and sensor assistance data.

[0065] The perception computing auxiliary data refers to data used to assist network-side devices in calculating perception measurement results, and optionally includes at least one of perception signal sending node information and transmission path information. The sensor auxiliary data is used to assist the network-side devices in obtaining perception results, and optionally includes perception information of sensors, where the sensors refer to devices that perform perception based on non-3GPP-defined wireless signals (e.g., mobile sensors, environmental sensors, location sensors, wireless local area networks (WLANs), Bluetooth, etc.).

[0066] Step S12: the terminal sends a second message or a third message to the network side device according to the first message, the second message is used to provide the perception assistance data, and the third message is used to reject the request for the perception assistance data.

[0067] In an embodiment of the present application, when the network-side device is performing perception, it requests the terminal's perception-assisted data from the terminal. The terminal can determine whether to provide the network-side device based on its willingness or whether there is perception-assisted data that meets the requirements. Since the number of terminals is huge and they are widely distributed in different geographical locations, the network-side device can more flexibly use the perception-assisted data provided by the terminal to obtain the required perception results, thereby improving perception performance. At the same time, compared to the method in which the terminal receives perception signals for measurement and reports perception measurement quantities, or the method in which the terminal sends a perception-specific reference signal, providing perception-assisted data through the terminal also minimizes the additional overhead of the terminal in perception.

[0068] In some embodiments, optionally, the network side device may be a wireless access network node or a core network function node.

[0069] In some embodiments, optionally, the terminal determines whether it is willing to provide the perception assistance data based on the first message; if not, it sends a third message to reject the request for the perception assistance data; if it is willing, it sends a second message to provide the perception assistance data.

[0070] In some embodiments, optionally, the third message may further include a rejection reason, such as unwillingness to provide the perception assistance data.

[0071] In some embodiments, optionally, the first message includes at least one of the following:

[0072] 1) Perception of auxiliary data types;

[0073] In some embodiments, optionally, the perception assistance data type includes at least one of perception calculation assistance data and sensor assistance data.

[0074] In some embodiments, optionally, when the network-side device performs perception based only on the terminal's uplink perception signal (hereinafter referred to as the perception signal in the embodiments of this application), the perception assistance data type may be perception calculation assistance data. When the network-side device performs perception based only on the terminal's sensor data, the perception assistance data type may be sensor assistance data. When the network-side device requires both, the perception assistance data type includes perception calculation assistance data and sensor assistance data.

[0075] 2) Perceive the effective area of ​​auxiliary data;

[0076] In some embodiments, optionally, the valid area is represented by at least one of a general area description (such as longitude, latitude, and altitude), a cell identifier, an access network notification area (RAN-based Notification Area, RNA), and one or more cell downlink received signal strength intervals. That is, the terminal is required to provide the requested perception assistance data within the valid area. In particular, for periodic perception assistance data, each time the terminal needs to send perception assistance data, it can determine whether it is currently within the valid area based on the valid area, thereby determining whether the perception assistance data can be provided.

[0077] 3) a request indication for sensing the validity period of the assistance data;

[0078] Optionally, when the first message includes this field (a request indication of the valid time of the perception assistance data) or through the value of the specified information unit (for example, a request when the specified bit is 1 and no request when the bit is 0), it indicates a request for the valid time of the perception assistance data.

[0079] 4) segment information of the first message;

[0080] When the first message is large, the network device may divide the first message into multiple segments and transmit the segments in segments. The segmentation information of the first message may include at least one of the following: indication information indicating whether the first message is one of the multiple segments, indication information indicating the sequence number of the current segment, and indication information indicating the size of the current segment.

[0081] 5) Periodic sensing assistance data request indication;

[0082] This field is used to indicate a request for periodic transmission of perception assistance data.

[0083] 6) a perception signal identifier used by the network-side device, the perception signal identifier including at least one of a perception signal type identifier and a configuration identifier; the configuration identifier is used to indicate perception signal resource information;

[0084] Specifically, the type of perception signal that the network-side device can use in perception includes at least one of a reference signal and an uplink data signal. Among them, one method of identifying a perception signal is that the reference signal includes at least one of the following: a perception reference signal dedicated to perception, a communication reference signal dedicated to communication, and a reference signal that can be used for both perception and communication. For the sake of convenience, they are collectively referred to as reference signals in the following description and will not be described one by one. Another method of identifying a perception signal based on a 5G reference signal is to identify it based on the name of the reference signal. For example, the reference signal includes a channel sounding reference signal (SRS), a demodulation reference signal (DMRS), a phase tracking reference signal (Phase-tracking reference signal), and at least one of the uplink reference signals newly defined in 6G. Among them, the uplink data signal refers to the uplink data sent in the communication. Once the network-side device successfully demodulates (for example, the cyclic redundancy check (CRC) is correct), the network-side device can use the successfully demodulated uplink data signal as a known signal, and then perform perception measurement data estimation. The uplink data signal is a perception signal potentially used by the network side device for perception.

[0085] Optionally, the perception signal identifier at least indicates a perception signal type, such as a reference signal or uplink data; another example is a perception reference signal, a communication reference signal, or a communication perception reference signal; another example is an SRS, a DMRS, or a PT-RS. Optionally, the perception signal identifier may also indicate configuration information of one or a group of perception signals. In an embodiment of the present application, one method is to indicate the perception signal type in the perception signal identifier. If it is also necessary to indicate the configuration of one or a group of perception signals, a perception signal configuration identifier may be added to indicate the configuration of each perception signal. Another method is to use the perception signal identifier to indicate the type identifier of the perception signal and the configuration identifier of the perception signal.

[0086] The configuration identifier of the perception signal is used to indicate perception signal resource information.

[0087] In an embodiment of the present application, the perception signal resource information may uniquely identify one or a group of perception signals, that is, the perception signal resource information may be resource information of one or more perception signals. The perception signal resource information may indicate the time-frequency resources for transmitting the perception signal (e.g., SRS, DMRS, PT-RS, uplink data signal, etc.). For example, when the perception signal identifier used by the network-side device includes multiple reference signals, or when the perception signal identifier used by the network-side device includes a reference signal of multiple resources, the perception signal requested by the network-side device may be further determined based on the perception signal resource information.

[0088] The perception signal resource information may be configured, for example, through Radio Resource Control (RRC), Media Access Control Control Element (MAC CE) or Downlink Control Information (DCI).

[0089] This field can also be used in conjunction with other fields. For example, when the network-side device requests the terminal to provide the expected LOS transmission path of a signal (reference signal or uplink data signal) corresponding to a certain resource from the terminal to the perception target, this field can be the Physical Uplink Shared Channel (PUSCH) of subframe x and time slot 0.

[0090] For another example, the perception signal identifier used by the network side device may also be a reference signal list and / or an uplink data signal list. The reference signal list includes at least one reference signal, and the uplink data signal list includes at least one uplink data information. An example is as follows:

[0091] Reference Signal List

[0092] - Reference signal 1 (such as SRS)

[0093] ■Subframe x time slot y

[0094] ■Subframe m time slot n

[0095] - Reference signal 2 (such as DMRS)

[0096] It should be noted that within a time period of approximately T, if a terminal transmits a reference signal only at time T1, then it can be identified by reference signal 1, without the need for a configuration identifier for subframe x, time slot y. Within a time period of approximately T, if a terminal transmits reference signals at multiple times, then the configuration identifier can be used to indicate which reference signal's corresponding perception assistance data is required.

[0097] Uplink data signal list

[0098] ■Subframe x time slot y

[0099] ■Subframe m time slot n

[0100] As mentioned above, the uplink data signal refers to the uplink data sent during communication, and no further distinction is made between uplink data types. Therefore, the uplink data signal list mainly uses configuration identifiers as examples.

[0101] 7) Sending uplink resource configuration information of the perception assistance data.

[0102] In some embodiments, optionally, one approach is for the uplink resource configuration information to indicate the time-frequency resources for transmitting the perception assistance data and the order in which each terminal uses the time-frequency resources, thereby ensuring that each terminal does not collide on the indicated resources. Considering that some terminals may not provide perception assistance data, another approach is for the uplink resource configuration information to indicate the time-frequency resources for transmitting the perception assistance data, and to divide the multiple terminals into multiple terminal groups, indicating the order in which each terminal group uses the time-frequency resources.

[0103] In some embodiments, optionally, if the perception assistance data includes perception computing assistance data, the first message further includes at least one of the following:

[0104] 1) Perceive the target reference position;

[0105] In some embodiments, optionally, the network-side device may determine one or more perception target reference locations based on perception requirements, etc.

[0106] In some embodiments, the sensing target reference location can optionally be represented by latitude, longitude, and altitude. If the network-side device requests the terminal to provide the expected probability of LOS path transmission from the sensing signal transmitting terminal (i.e., the sensing signal transmitting node, here the terminal requested by the aforementioned network device) to the sensing target, this field can be used by the network-side device to determine the expected probability of LOS path transmission. The expected probability can also be called the expected probability.

[0107] 2) Request indication of terminal location information;

[0108] When this field (request indication of terminal location information) is included in the first message or the value of the specified information unit is specified (for example, when the specified bit is 1, it indicates requesting terminal location information, and when the bit is 0, it indicates not requesting terminal location information), it indicates requesting terminal location information.

[0109] In some embodiments, optionally, the terminal location information request indication is used to indicate at least one of the following:

[0110] Request terminal location information without timestamp or with timestamp;

[0111] Whether to request high-precision (e.g., centimeter (cm) level) terminal location information.

[0112] 3) Request indication of terminal transmission (UE Tx) timing error group information;

[0113] One definition of a UE Tx timing error group is that the Tx timing errors of the transmitting antenna channels are within a certain range. For example, antenna channels with a common clock source typically have smaller timing errors.

[0114] Optionally, when the word is included in the first message or by specifying the value of the information unit (for example, when the specified bit is 1, it indicates that the terminal is requested to send (UE Tx) timing error group information, and when the bit is 0, it indicates that the terminal is not requested to send (UE Tx) timing error group information), it indicates that the terminal is requested to send (UE Tx) timing error group information.

[0115] If the frequency error is represented by Fe, then the time drift Delta T within time T = ±Fe×T. In addition, if the frequency drift is identified as F′, then the time drift Delta T within time T = ±0.5×F′×T 2 Therefore, according to the mapping relationship in the formula, the terminal transmission (UE Tx) timing error group can also be mapped to the terminal transmission (UE Tx) frequency error group.

[0116] 4) Request indication of terminal transmission (UE Tx) clock accuracy;

[0117] The terminal transmission (UE Tx) clock accuracy refers to the accuracy of the clock used by the transmission reception point (TRP) to send data, usually expressed in parts per million (ppm). The higher the clock accuracy, the more accurate and stable the clock used by the TRP to send data. When this field is included in the first message or by specifying the value of the information unit (for example, when the specified bit is 1, it indicates that the terminal transmission (UE Tx) clock accuracy is requested, and when the bit is 0, it indicates that the terminal transmission (UE Tx) clock accuracy is not requested), it indicates that the terminal transmission (UE Tx) clock accuracy information of the serving cell (or primary serving cell) is requested.

[0118] 5) The terminal sends a request indication for clock deviation group information;

[0119] A terminal's transmit clock deviation group is associated with one or more sensing signal resources. These resources have clock frequency deviations within a certain range, for example, from the same clock source. Network devices can use this group to estimate frequency deviations, resulting in more accurate Doppler measurements.

[0120] In some embodiments, optionally, when this field is included in the first message or by specifying the value of the information unit (for example, when the specified bit is 1, it indicates that the terminal is requested to send clock deviation group information, and when the bit is 0, it indicates that the terminal is not requested to send clock deviation group information), it indicates that the terminal is requested to send clock deviation group information.

[0121] 6) Request indication for LOS-NLOS assistance information.

[0122] The LOS-NLOS assistance information may also be referred to as LOS-NLOS probability.

[0123] In some embodiments, optionally, when the first message includes this field or the value of the specified information unit is specified (for example, when the specified bit is 1, it indicates request, and when the bit is 0, it indicates no request), it indicates requesting LOS-NLOS assistance information.

[0124] Optionally, the LOS-NLOS assistance information may be associated with perception signal resource information indicated by a certain perception signal identifier.

[0125] The LOS-NLOS assistance information may be of a soft value type and / or a hard value type. One type is represented by the probability of an LOS propagation path, also known as a soft information type. For example, a value of 0 represents NLOS, and other values ​​between 0 and 1 (such as 0.1) represent the probability of an LOS propagation path. Another type of LOS-NLOS assistance information is represented by a judgment value of LOS or NLOS, also known as a hard information type. For example, 0 (False) represents NLOS, and 1 (True) represents LOS. The granularity of the LOS-NLOS assistance information may be TPR granularity and / or resource granularity. One granularity of the LOS-NLOS assistance information is to represent the expected probability of an LOS transmission path for a sensing signal from one or a group of TPRs of a terminal to a sensing target, also known as TRP-specific granularity. Another granularity of the LOS-NLOS assistance information is to represent the expected probability of an LOS transmission path for a sensing signal from a terminal to a sensing target corresponding to one or a group of sensing signal resources, also known as resource-specific granularity.

[0126] In some embodiments, optionally, the sensing assistance data provided by the terminal includes a sensing signal resource, and the LOS-NLOS assistance information includes:

[0127] a first value, where the first value is a value corresponding to an expected likelihood of a LOS propagation path of the sensing signal corresponding to the sensing signal resource from the terminal to the sensing target;

[0131] a third numerical list, where the third numerical value represents an expected probability of an LOS transmission path of the sensing signal corresponding to each sensing signal resource from the terminal to the sensing target (such as the aforementioned sensing target reference position);

[0132] The fourth value and the perception signal resource information corresponding to the fourth value indicate that the fourth value represents a maximum value among expected possibilities of LOS transmission paths of the perception signals corresponding to all the perception signal resources from the terminal to the perception target.

[0133] The above-mentioned values ​​may also be combined as needed. For example, the second value list and the third value list together form a definition of LOS-NLOS auxiliary information.

[0134] In an embodiment of the present application, the request indication for the LOS-NLOS assistance information may include at least one of the following: an indication of whether to request LOS-NLOS assistance information, and an indication of which type of LOS-NLOS assistance information is requested. If the LOS-NLOS assistance information includes the above two types of information, it can also be indicated by multiple bits. For example, by two bits, one bit is used to indicate whether to request LOS-NLOS assistance information, and one bit is used to indicate which type of LOS-NLOS assistance information is requested. For example, when the two bits are 10, it indicates a request for the expected possibility of the LOS transmission path of the perception signal corresponding to the perception signal resource from the terminal to the perception target, and when the two bits are 11, it indicates a request for the total expected possibility of the LOS transmission path of the perception signal corresponding to all perception signal resources from the terminal to the perception target.

[0135] In some embodiments, optionally, if the perception assistance data includes sensor assistance data, the first message further includes at least one of the following:

[0136] 1) Request indication of WLAN information;

[0138] 2) Bluetooth information request indication;

[0139] When the first message includes this field or the value of the specified information unit is specified (for example, a request is indicated when the specified bit is 1, and no request is indicated when the bit is 0), it indicates a request for Bluetooth information.

[0140] 3) Request instructions for camera information;

[0141] When this field is included in the first message or by specifying the value of the information unit (for example, a request when the specified bit is 1, and no request when the bit is 0), it indicates a request for camera information (such as a video or picture with a timestamp, etc.).

[0142] In some embodiments, optionally, the camera information can be used as label data perceived by the terminal side based on artificial intelligence (AI).

Therefore, the Y-axis doesn't point north, but rather to some other reference point. This reference point can be offset by the same order of magnitude as the gyroscope's Z-axis drift. Because the Game Rotation Vector Sensor doesn't use a magnetic field, relative rotation is more accurate and unaffected by magnetic field variations.

At the same time, compared to the method in which the terminal receives perception signals for measurement and reports perception measurement quantities, or the method in which the terminal sends a perception-specific reference signal, providing perception-assisted data through the terminal also minimizes the additional overhead of the terminal in perception.

[0296] The above-mentioned method for transmitting perception-assisted data can be applied to the following two aspects: on the one hand, when one or more terminals are close to the perception target or perception area, the network-side device can obtain at least one of the perception measurement and perception result based on the uplink reference signal or the correctly demodulated uplink data signal; on the other hand, when the network-side device needs to calculate the perception result, or needs to train the AI ​​model for calculating the perception result, or needs to improve the accuracy of the perception result, it can obtain the perception-assisted data of the appropriate terminal.

[0297] The following describes the method for transmitting the perception-assisted data in the embodiment of the present application with examples in combination with specific application scenarios.

[0298] Example 1: Network side device requests perception calculation auxiliary data from UE

[0299] In the embodiments of the present application, it is assumed that the network-side device determines one or more UEs for requesting perception calculation auxiliary data based on at least one of the terminal perception signal configuration (such as the configuration of uplink data signal transmission or reference signal configuration), uplink measurement, terminal position estimation, terminal uplink data CRC check result, and terminal capabilities. If the network-side device obtains the perception auxiliary data provided by the UE, it can be used to calculate the perception results, calculate the AI ​​model training of the perception results, correct the perception results, or improve the perception performance by combining other perception data.

[0300] The method for transmitting perception assistance data in an embodiment of the present application includes the following steps:

[0301] Step 1: The network-side device determines one or more UEs for requesting perception calculation auxiliary data based on at least one of the terminal perception signal configuration (such as the configuration of uplink data signal transmission or the configuration of reference signals), uplink measurement, terminal position estimation, terminal uplink data CRC check result, and terminal capabilities. For example, when the network-side device is performing perception, based on the above information, it finds that the uplink data CRC check of UE A near the perception target or in the perception area is correct, and the uplink data bandwidth meets the perception resolution requirements. In addition, optionally, UE A also has a sensor corresponding to the perception result (such as a humidity sensor, etc.). At this time, the network side determines to request perception calculation auxiliary data from UE A.

[0302] The network-side device sends a first message to the determined UE, where the first message is used to request perception assistance data, where the perception assistance data is used to assist the network-side device in perception, and the perception assistance data includes at least one of perception calculation assistance data and sensor assistance data. The first message includes at least one of the following:

[0303] 1) Perception of auxiliary data types;

[0304] In some embodiments, optionally, the perception assistance data type includes at least one of perception calculation assistance data and sensor assistance data.

[0305] Perception computing auxiliary data refers to information used to assist in the calculation of perception measurement data or perception results. Sensor auxiliary data refers to information related to devices that perform perception based on non-3GPP-defined wireless signals (such as mobile sensors, environmental sensors, location sensors, wireless local area networks (WLAN), Bluetooth, etc.).

[0306] When the network-side device performs perception based solely on the UE's sensor signals, the type of perception assistance data may be perception calculation assistance data. When the network-side device performs perception based solely on the UE's sensor data, the type of perception assistance data may be sensor assistance data. When the network-side device requires both, the type of perception assistance data includes perception calculation assistance data and sensor assistance data.

[0307] 2) Perceive the effective area of ​​auxiliary data;

[0308] In some embodiments, optionally, the valid area is represented by at least one of a general area description (such as longitude, latitude, and altitude), a cell identifier, an access network notification area (RAN-based Notification Area, RNA), and one or more cell downlink received signal strength intervals. That is, the terminal is required to provide the requested perception assistance data within the valid area. In particular, for periodic perception assistance data, each time the terminal needs to send perception assistance data, it can determine whether it is currently within the valid area based on the valid area, thereby determining whether the perception assistance data can be provided.

[0309] 3) a request indication for sensing the validity period of the assistance data;

[0310] Optionally, when the first message includes this field (a request indication of the valid time of the perception assistance data) or through the value of the specified information unit (for example, a request when the specified bit is 1 and no request when the bit is 0), it indicates a request for the valid time of the perception assistance data.

[0311] 4) segment information of the first message;

[0312] When the first message is large, the network device may divide the first message into multiple segments and transmit the segments in segments. The segmentation information of the first message may include at least one of the following: indication information indicating whether the first message is one of the multiple segments, indication information indicating the sequence number of the current segment, and indication information indicating the size of the current segment.

[0313] 5) Periodic sensing assistance data request indication;

[0314] This field is used to indicate a request for periodic transmission of perception assistance data.

[0315] 6) a perception signal identifier used by the network-side device, the perception signal identifier including at least one of a perception signal type identifier and a configuration identifier; the configuration identifier is used to indicate perception signal resource information;

[0316] 7) Sending uplink resource configuration information of the perception assistance data.

[0317] 8) Perceiving the target reference position;

[0318] In some embodiments, the network-side device may optionally determine one or more sensing target reference locations based on sensing requirements, etc. In some embodiments, the sensing target reference locations may optionally be represented by latitude, longitude, altitude, etc. If the network-side device requests the terminal to provide a sensing signal (including at least one of a reference signal and an uplink data signal) indicating the expected probability of LOS path transmission from the terminal to the sensing target, this field may be used by the network-side device to determine the expected probability of LOS path transmission.

[0319] 9) Request indication of terminal location information;

[0320] When this field (request indication of terminal location information) is included in the first message or the value of the specified information unit is specified (for example, when the specified bit is 1, it indicates requesting terminal location information, and when the bit is 0, it indicates not requesting terminal location information), it indicates requesting terminal location information.

[0321] In some embodiments, optionally, the terminal location information request indication is used to indicate at least one of the following:

[0322] Request terminal location information without timestamp or with timestamp;

[0323] Whether to request high-precision (e.g., centimeter (cm) level) terminal location information.

[0324] 10) Request indication of terminal sending (UE Tx) timing error group information;

[0325] One definition of a UE Tx timing error group is that the Tx timing errors of the transmitting antenna channels are within a certain range. For example, antenna channels with a common clock source typically have smaller timing errors.

[0326] Optionally, when the word is included in the first message or by specifying the value of the information unit (for example, when the specified bit is 1, it indicates that the terminal is requested to send (UE Tx) timing error group information, and when the bit is 0, it indicates that the terminal is not requested to send (UE Tx) timing error group information), it indicates that the terminal is requested to send (UE Tx) timing error group information.

[0327] If the frequency error is represented by Fe, then the time drift Delta T within time T = ±Fe×T. In addition, if the frequency drift is identified as F′, then the time drift Delta T within time T = ±0.5×F′×T 2 Therefore, according to the mapping relationship in the formula, the terminal transmission (UE Tx) timing error group can also be mapped to the terminal transmission (UE Tx) frequency error group.

[0328] 11) Request indication of terminal transmission (UE Tx) clock accuracy;

[0329] The terminal transmission (UE Tx) clock accuracy refers to the accuracy of the clock used by the transmission reception point (TRP) to send data, usually expressed in parts per million (ppm). The higher the clock accuracy, the more accurate and stable the clock used by the TRP to send data. When this field is included in the first message or by specifying the value of the information unit (for example, when the specified bit is 1, it indicates that the terminal transmission (UE Tx) clock accuracy is requested, and when the bit is 0, it indicates that the terminal transmission (UE Tx) clock accuracy is not requested), it indicates that the terminal transmission (UE Tx) clock accuracy information of the serving cell (or primary serving cell) is requested.

[0330] 12) The terminal sends a request indication for clock deviation group information;

[0331] A terminal's transmit clock deviation group is associated with one or more sensing signal resources. These resources have clock frequency deviations within a certain range, for example, from the same clock source. Network devices can use this group to estimate frequency deviations, resulting in more accurate Doppler measurements.

[0332] In some embodiments, optionally, when this field is included in the first message or by specifying the value of the information unit (for example, when the specified bit is 1, it indicates that the terminal is requested to send clock deviation group information, and when the bit is 0, it indicates that the terminal is not requested to send clock deviation group information), it indicates that the terminal is requested to send clock deviation group information.

[0333] 13) Request indication for LOS-NLOS assistance information.

[0334] In some embodiments, optionally, when the first message includes this field or the value of the specified information unit is specified (for example, when the specified bit is 1, it indicates request, and when the bit is 0, it indicates no request), it indicates requesting LOS-NLOS assistance information.

[0335] Optionally, the LOS-NLOS assistance information may be associated with a certain perception signal identifier (such as the aforementioned perception signal resource information).

[0336] In some embodiments, optionally, when the first message includes sensing signal resource information, the LOS-NLOS assistance information includes:

[0343] The fourth value and the perception signal resource information corresponding to the fourth value indicate that the fourth value represents a maximum value among expected possibilities of LOS transmission paths of the perception signals corresponding to all the perception signal resources from the terminal to the perception target.

[0344] The above-mentioned values ​​may also be combined as needed. For example, the second value list and the third value list together form a definition of LOS-NLOS auxiliary information.

[0345] In an embodiment of the present application, the request indication for the LOS-NLOS assistance information may include at least one of the following: an indication of whether to request LOS-NLOS assistance information, and an indication of which type of LOS-NLOS assistance information is requested. If the LOS-NLOS assistance information includes the above two types of information, it can also be indicated by multiple bits. For example, by two bits, one bit is used to indicate whether to request LOS-NLOS assistance information, and one bit is used to indicate which type of LOS-NLOS assistance information is requested. For example, when the two bits are 10, it indicates a request for the expected possibility of the LOS transmission path of the perception signal corresponding to the perception signal resource from the terminal to the perception target, and when the two bits are 11, it indicates a request for the total expected possibility of the LOS transmission path of the perception signal corresponding to all perception signal resources from the terminal to the perception target.

[0346] It should be noted that, in an embodiment of the present application, when the network side device determines multiple UEs to provide perception assistance data, the first message can be sent to the multiple UEs by multicast or broadcast.

[0347] Step 2: The UE receives the first message sent by the network-side device and determines whether it is willing to provide the perception assistance data based on the first message. The UE sends a second message or a third message to the network-side device, where the third message is used to reject the request for the perception assistance data, or the second message is used to provide the perception assistance data. When rejecting the request for the perception assistance data, the third message may optionally include a reason for the rejection, such as unwillingness to provide the perception assistance data.

[0348] When the terminal provides the sensing assistance data, the second message includes at least one of the following:

[0349] 1) Segment information of the second message;

[0350] When the second message is large, the terminal may divide the second message into multiple segments and transmit the segments in segments. The segmentation information of the second message may include at least one of the following: indication information indicating whether the second message is one of the multiple segments, indication information indicating the sequence number of the current segment, and indication information indicating the size of the current segment.

[0358] 6) Terminal sending clock accuracy;

[0359] 7) The terminal sends clock deviation group information;

[0360] 8) LOS-NLOS auxiliary information.

[0361] In some embodiments, optionally, when the first message includes sensing signal resource information, the LOS-NLOS assistance information includes:

[0362] The sensing assistance data provided by the terminal includes a sensing signal resource, and the LOS-NLOS assistance information includes:

[0363] a first value, where the first value is a value corresponding to an expected probability of an LOS transmission path of the perception signal corresponding to the perception signal resource from the terminal to the perception target;

[0364] or,

[0365] The sensing assistance data provided by the terminal includes multiple sensing signal resources, and the LOS-NLOS assistance information includes at least one of the following:

[0366] a second value, where the second value represents a total expected probability of an LOS transmission path of the sensing signals corresponding to all the sensing signal resources from the terminal to the sensing target;

[0367] a third numerical list, where the third numerical value represents an expected probability of an LOS transmission path of the sensing signal corresponding to each sensing signal resource from the terminal to the sensing target (such as the aforementioned sensing target reference position);

[0368] The fourth value and the perception signal resource information corresponding to the fourth value indicate that the fourth value represents a maximum value among expected possibilities of LOS transmission paths of the perception signals corresponding to all the perception signal resources from the terminal to the perception target.

[0369] In some embodiments, optionally, when the UE provides periodic sensing assistance data and the first message includes a valid area for the sensing assistance data, the UE needs to check whether it is within the valid area before providing the sensing assistance data each time. If it is still within the valid area, a second message is sent to provide the sensing assistance data; otherwise, the sensing assistance data is not sent. Optionally, the UE may send a message to indicate that the UE has left the valid area.

[0370] Step 3: The network device receives the second message. If the perception assistance data is obtained, the network device obtains the desired perception result based on the perception assistance data and the perception measurement of at least one of the uplink reference signal and the uplink data signal. Alternatively, the network device calculates the perception result in combination with other perception data obtained by the network device, or uses the data to train an AI model for calculating the perception result.

[0371] Example 2: The network side device requests sensor assistance data from the UE

[0372] In an embodiment of the present application, a network-side device requests sensory assistance data from multiple UEs or UE groups. In order to improve efficiency, the network-side device can send a first message to the corresponding multiple UEs by multicast or broadcast. Optionally, the uplink resources for sending sensory assistance data of different UEs (uplink resource configuration information for sending the sensory assistance data) are indicated in the first message, and each UE transmits the assistance data on the corresponding uplink resources. In addition, since the sensor assistance data is closely related to the UE capability, the network-side device needs to obtain the UE capability information first.

[0373] The method for transmitting perception assistance data in an embodiment of the present application includes at least one of the following:

[0374] Step 1: This step is optional. The network-side device sends a capability request message to the UE to request UE capability information.

[0375] Step 2: The network-side device determines multiple UEs for requesting perception calculation auxiliary data based on the terminal perception signal configuration (such as the configuration of uplink data signal transmission or reference signal configuration, etc.), uplink measurement, terminal position estimation, terminal uplink data CRC check result, and at least one of the terminal capabilities. For example, when the network-side device is performing perception, it collects data for training the AI ​​model that calculates the perception results. One case is that AI model training requires a large amount of UE uplink measurement data and corresponding sensor information.

[0376] The network-side device sends a first message to the determined UE. To improve efficiency, the first message may be sent to the determined multiple UEs via multicast or broadcast. The first message includes at least one of the following:

[0377] 1) Perception of auxiliary data types;

[0378] In some embodiments, optionally, the perception assistance data type includes at least one of perception calculation assistance data and sensor assistance data.

Sensor auxiliary data refers to information related to devices that perform perception based on non-3GPP-defined wireless signals (such as mobile sensors, environmental sensors, location sensors, wireless local area networks (WLAN), Bluetooth, etc.).

[0380] When the network-side device performs perception based solely on the UE's sensor signals, the type of perception assistance data may be perception calculation assistance data. When the network-side device performs perception based solely on the UE's sensor data, the type of perception assistance data may be sensor assistance data. When the network-side device requires both, the type of perception assistance data includes perception calculation assistance data and sensor assistance data.

That is, the terminal is required to provide the requested perception assistance data within the valid area. In particular, for periodic perception assistance data, each time the terminal needs to send perception assistance data, it can determine whether it is currently within the valid area based on the valid area, thereby determining whether the perception assistance data can be provided.

[0383] 3) a request indication for sensing the validity period of the assistance data;

[0384] Optionally, when the first message includes this field (a request indication of the valid time of the perception assistance data) or through the value of the specified information unit (for example, a request when the specified bit is 1 and no request when the bit is 0), it indicates a request for the valid time of the perception assistance data.

[0385] 4) segment information of the first message;

[0394] 9) Request instructions for camera information;

[0395] When this field is included in the first message or by specifying the value of the information unit (for example, a request when the specified bit is 1, and no request when the bit is 0), it indicates a request for camera information (such as a video or picture with a timestamp, etc.).

[0396] In some embodiments, optionally, the camera information can be used as label data perceived by the terminal side based on artificial intelligence (AI).

[0406] Optionally, the Game Rotation Vector Sensor Information Request Indication can be used to indicate whether to request Game Rotation Vector Sensor information. The Game Rotation Vector Sensor is identical to the Rotation Vector Sensor, except it doesn't use the Earth's magnetic field. Therefore, the Y-axis doesn't point north, but rather to some other reference point. This reference point can be offset by the same order of magnitude as the gyroscope's Z-axis drift. Because the Game Rotation Vector Sensor doesn't use a magnetic field, relative rotation is more accurate and unaffected by magnetic field variations.

[0407] 15) Request indication of pace detector sensor information;

[0408] Optionally, the request indication of the step detector sensor information may be used to indicate at least one of the following: whether to request the step detector sensor information, and the type of the requested step detector sensor information, for example, the step detector sensor triggers an event every time the user takes a step.

[0424] Optionally, the first message may further include uplink resource configuration information for sending the perception assistance data. One way is that the uplink resource configuration information indicates the time-frequency resources for sending the perception assistance data and the order in which each UE uses the time-frequency resources, thereby ensuring that each UE does not collide on the indicated resources. Taking into account that some UEs may not provide perception assistance data, another way is that the uplink resource configuration information indicates the time-frequency resources for sending the perception assistance data, and divides the above-mentioned multiple UEs into multiple UE groups, indicating the order in which each UE group uses the time-frequency resources.

[0425] Step 2: The UE receives the first message sent by the network device and determines whether it is willing to provide the perception assistance data based on the first message.

Therefore, the Y axis doesn't point north, but rather to some other reference. This reference can be offset by the same order of magnitude as the gyroscope's drift around the Z axis. Because the Game Rotation Vector Sensor doesn't use a magnetic field, relative rotation is more accurate and unaffected by magnetic field variations.

[0441] 12) Step detector sensor information; for example, the step detector sensor triggers an event every time the user takes a step;

[0442] 13) Geomagnetic field sensor information; for example, changes in the Earth's magnetic field monitored by the geomagnetic field sensor;

[0448] In some embodiments, optionally, when the UE provides periodic sensing assistance data and the first message includes a valid area for the sensing assistance data, the UE needs to check whether it is within the valid area before providing the sensing assistance data each time. If it is still within the valid area, a second message is sent to provide the sensing assistance data; otherwise, the sensing assistance data is not sent. Optionally, the UE may send a message to indicate that the UE has left the valid area.

[0449] Step 3: The network device receives the second message. If the perception assistance data is obtained, the network device obtains the desired perception result based on the perception assistance data and the perception measurement of at least one of the uplink reference signal and the uplink data signal. Alternatively, the network device calculates the perception result in combination with other perception data obtained by the network device, or uses the data to train an AI model for calculating the perception result.

[0450] The method for transmitting perception-assisted data provided in the embodiment of the present application can be executed by a transmission device for perception-assisted data. In the embodiment of the present application, the method for transmitting perception-assisted data is executed by a transmission device for perception-assisted data as an example to illustrate the transmission device for perception-assisted data provided in the embodiment of the present application.

[0451] The transmission device of the perception-assisted data in the embodiment of the present application can be an electronic device, such as an electronic device with an operating system, or a component in an electronic device, such as an integrated circuit or a chip.

[0454] The sending module 72 is used to send a second message or a third message to the network side device according to the first message, the second message is used to provide the perception assistance data, and the third message is used to reject the request for the perception assistance data.

[0455] In an embodiment of the present application, when the network-side device is performing perception, it requests the terminal's perception-assisted data from the terminal. The terminal can determine whether to provide the network-side device based on its willingness or whether there is perception-assisted data that meets the requirements. Since the number of terminals is huge and they are widely distributed in different geographical locations, the network-side device can more flexibly use the perception-assisted data provided by the terminal to obtain the required perception results, thereby improving perception performance. At the same time, compared to the method in which the terminal receives perception signals for measurement and reports perception measurement quantities, or the method in which the terminal sends a perception-specific reference signal, providing perception-assisted data through the terminal also minimizes the additional overhead of the terminal in perception.
