[0033] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0034] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, not limited in number; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0035] It is worth noting that the technologies described in this application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in this application are often used interchangeably, and the described technologies can be used in the systems and radio technologies mentioned above, as well as in other systems and radio technologies. The following description describes New Radio (NR) systems for illustrative purposes, and NR terminology is used in most of the following description. These technologies can also be applied to applications beyond NR systems, such as 6th generation (6G) radio systems. th Generation 6G communication system.

[0036] To enable those skilled in the art to better understand the embodiments of this application, the following description is provided first.

[0037] Future mobile communication systems, such as B5G or 6G systems, will possess sensing capabilities in addition to communication capabilities. Sensing capabilities refer to the ability of one or more devices to sense the location, distance, and speed of target objects through the transmission and reception of wireless signals, or to detect, track, identify, and image target objects, events, or environments. With the deployment of small base stations using high-frequency, high-bandwidth technologies such as millimeter waves and terahertz waves in 6G networks, the resolution of sensing will be significantly improved compared to centimeter waves, enabling 6G networks to provide more refined sensing services.

[0038] Some sensing applications, such as environmental reconstruction, require the cooperation of positioning functions when the sensing signal measurement party is the user equipment (UE, also known as the terminal). This means acquiring the UE's location information and reconstructing an environmental map based on the UE's location information and measured environmental reflection point information. Alternatively, the base station can sense and reconstruct the surrounding environment using a self-transmitting and self-receiving mode, and then use this reconstructed information to assist the UE's positioning. Other sensing applications, such as indoor motion recognition, breathing detection, and weather detection, rely on the UE as the signal sender or receiver. Acquiring the UE's location information allows for determining the sensing signal configuration or measurement quantities based on the transceiver's location and the location of the target or sensing area, or assisting in calculating the sensing results, thereby achieving higher sensing accuracy and providing better sensing services. However, there is currently no solution in the relevant technologies for combining positioning information with sensing.

[0039] The perception and positioning method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0040] like Figure 1 As shown, this application provides a sensing and localization method, including:

[0041] Step 101: The first communication device receives the sensing requirements.

[0042] The first communication device may specifically be a sensing network function or a sensing network element.

[0043] In this step, the sensing requirement can be initiated by a third-party application, the core network (or network management system or base station), or a terminal.

[0044] For example, a third-party application sends the sensing requirement to the application server (including an intranet server, such as IMS or an extranet server); the application server sends the sensing requirement to the sensing network function / sensing network element; or, the application server sends the sensing requirement to the Access and Mobility Management Function (AMF), and the AMF selects at least one sensing network function / sensing network element and sends the requirement to the sensing network function / sensing network element.

[0045] For example, the core network AMF selects at least one sensing network function / sensing element and sends the sensing request to the sensing network function / sensing element; or the AMF receives the sensing request sent by the network management system, selects at least one sensing network function / sensing element and forwards it to the sensing network function / sensing element; or the AMF receives the sensing request sent by the base station, selects at least one sensing network function / sensing element and forwards it to the sensing network function / sensing element.

[0046] For example, the UE sends a sensing requirement to the core network AMF via NAS signaling. The AMF selects at least one sensing network function / sensing element and sends the sensing requirement to the sensing network function / sensing element.

[0047] The aforementioned perception requirements include at least one of the following:

[0048] Perceive the target / object;

[0049] Sensing area;

[0050] Perceived result / perceived quantity;

[0051] Perceived Quality of Service (QoS);

[0052] Perceived performance metrics.

[0053] The aforementioned perception performance indicators include at least one of the following: perception accuracy / perception error, perception resolution, perception range, perception latency, detection probability, and false alarm probability.

[0054] Step 102: If the sensing requirement is a sensing requirement associated with the location service, the first communication device sends the sensing requirement to the second communication device and sends the location requirement to the third communication device.

[0055] After receiving the sensing request, the first communication device determines whether location service assistance is needed based on the sensing request. If the sensing request requires location service assistance, it determines that the sensing request is associated with the defined service, triggers the sensing and positioning combination process, sends the sensing request to the second communication device, and sends the positioning request to the third communication device.

[0056] The second communication device mentioned above may be a first base station and / or a first terminal associated with sensing requirements, and the third communication device mentioned above may be a location management function (LMF).

[0057] Specifically, sending a location request to a third communication device includes: sending the location request to the AMF, the AMF selecting at least one LMF, and sending the location request to the LMF.

[0058] The sensing and positioning method of this application embodiment receives a sensing request; when the sensing request is a sensing request associated with a positioning service, it sends the sensing request to a second communication device and a positioning request to a third communication device, thereby triggering a process of combining sensing and positioning, and thus achieving the purpose of sensing by combining positioning information.

[0059] Optionally, before sending the sensing request to the second communication device, the method further includes:

[0060] A first base station and a first terminal associated with the sensing requirement are identified, and the second communication device includes at least one of the first base station and the first terminal.

[0061] Optionally, the positioning requirement includes first indication information, which is information used to indicate the second communication device, such as the first indication information used to indicate the identification information of the first base station and / or the first terminal.

[0062] In this embodiment of the application, after receiving a location request, the third communication device determines the second base station and / or the second terminal associated with the location request, and sends the location request to the second base station and / or the second terminal. The method for determining the second base station and / or the second terminal may be based on the second communication device.

[0063] Optionally, after sending a sensing request to the second communication device and a positioning request to the third communication device, the method further includes:

[0064] Obtain signal configuration information, which includes at least one of the configuration information of sensing signals and the configuration information of positioning signals, and the signal configuration information is determined based on at least one of the sensing requirements and the positioning requirements;

[0065] The configuration information of the sensing signal is sent to a second communication device, and / or the configuration information of the positioning signal is sent to a fourth communication device, the fourth communication device including at least one of a second base station and a second terminal associated with the positioning requirement.

[0066] Optionally, the signal configuration information is determined by at least one of the first communication device and the third communication device.

[0067] In this embodiment of the application, the configuration information of the sensing signal and the configuration information of the positioning signal can be determined by the first communication device, or by the third communication device, or by the first communication device determining the configuration information of the sensing signal and the second communication device determining the configuration information of the positioning signal, or by the first communication device determining the configuration information of the positioning signal and the third communication device determining the configuration information of the sensing signal.

[0068] The aforementioned sensing signal and positioning signal can use the same reference signal or different reference signals. In one implementation, the sensing signal and positioning signal use different reference signals, which can be uplink or downlink signals, or one uplink and one downlink signal. The sensing network function / sensing element determines the configuration information of the sensing signal according to the sensing requirements, and the LMF determines the configuration information of the positioning signal according to the positioning requirements. In another implementation, the sensing signal and positioning signal use the same reference signal, which can be an uplink or downlink signal. In this implementation, a set of signal configuration information is determined, which includes the configuration information of the sensing signal and the configuration information of the positioning signal. The configuration information of the sensing signal and the configuration information of the positioning signal can be determined by one of the first communication device and the third communication device, and the determined signal configuration information is notified to the other party. In this implementation, the configuration information of the sensing signal and the configuration information of the positioning signal can also be jointly determined by the first communication device and the third communication device. Specifically, one party, such as the LMF, can first determine the configuration information of the positioning signal, send the configuration information of the positioning signal to the sensing network function / sensing element, and then the sensing network function / sensing element supplements the configuration information of the sensing signal.

[0069] Optionally, the configuration information of the sensing signal can also be determined based on sensing requirements and prior information (such as terminal location information).

[0070] Optionally, when the signal configuration information includes configuration information for sensing signals and configuration information for positioning signals, the signal configuration information further includes first identification information;

[0071] The first identification information is used to indicate that the signal configuration information is used for positioning measurement and sensing measurement.

[0072] In a specific embodiment of this application, the sensing signal and the positioning signal use the same reference signal, and the aforementioned fourth communication device is the same as the second communication device, i.e., the same base station or terminal performs the sensing measurement and positioning measurement. In this case, only one of the first and third communication devices needs to send the signal configuration information to the second or fourth communication device. When the configuration information of the sensing signal and the positioning signal uses the same configuration, the aforementioned first identification information indicates that the signal configuration information is used for both positioning and sensing measurement. When reporting the measurement results, the AMF knows that the measurement results need to be sent to both the first and third communication devices. Alternatively, if either the first or third communication device sends the signal configuration information or measurement quantity through the AMF, the AMF knows to forward the signal configuration information or measurement quantity to the sensing-associated base station / UE and the positioning-associated base station / UE, respectively.

[0073] Optionally, after sending a sensing request to the second communication device and a positioning request to the third communication device, the method further includes:

[0074] Acquire measurement quantities, which include at least one of: sensing measurement quantities, positioning measurement quantities, and common measurement quantities, wherein the common measurement quantities are used for positioning measurement and sensing measurement;

[0075] The measurement is sent to at least one of a second communication device and a fourth communication device, the fourth communication device including at least one of a second base station and a second terminal associated with the positioning requirement.

[0076] Optionally, the measurement quantity is determined by at least one of the first communication device and the third communication device.

[0077] Specifically, the first communication device can determine sensing measurements and / or common measurements, and the second communication device can determine positioning measurements and common measurements. The first communication device can determine the sensing measurements and / or common measurements itself, and acquire the positioning measurements and / or common measurements determined by the second communication device.

[0078] Optionally, the measurement quantity includes at least one of the following:

[0079] Channel matrix H;

[0080] Channel State Information (CSI), such as the amplitude and / or phase of the frequency domain channel response, or the I-channel and Q-channel signal characteristics of the frequency domain channel response, such as the amplitude of the I-channel and Q-channel signals;

[0081] Reference Signal Received Power (RSRP);

[0082] Received Signal Strength Indication (RSSI);

[0083] Channel power delay profile (PDP);

[0084] Puller power spectrum;

[0085] Doppler extension;

[0086] Coherent bandwidth;

[0087] Coherence time;

[0088] The power of each path in a multipath channel (including at least the first-arrival path, the LOS path, the first-order reflection path, and the multiple-order reflection paths);

[0089] The time delay of each path in a multipath channel;

[0090] The angle of each path in a multipath channel;

[0095] The time delay difference between the first antenna and the second antenna;

[0097] In addition, in this embodiment of the application, the configuration information of the signal and the above-mentioned measurement quantity may also be determined by the second communication device and / or the fourth communication device according to the sensing requirements and / or positioning requirements.

[0098] Optionally, the method in this application embodiment further includes:

[0099] Obtain the measurement result corresponding to the measurement quantity. The measurement result is obtained based on the signal configuration information and the measurement quantity. The signal configuration information includes at least one of the configuration information of the sensing signal and the configuration information of the positioning signal. The signal configuration information is determined based on at least one of the sensing requirements and the positioning requirements.

[0100] In this embodiment of the application, the second communication device executes a sensing measurement process based on the configuration information of the sensing signal, the sensing measurement quantity, and the common measurement quantity. The specific way to execute the sensing measurement process includes at least one of the following methods: base station self-transmission and self-reception, transmission and reception between base stations, base station transmission and UE reception, UE transmission and base station reception, UE self-transmission and self-reception, and transmission and reception between UEs.

[0101] The fourth communication device executes the positioning measurement process based on the configuration information of the positioning signal, positioning measurement quantities, and common measurement quantities. The specific execution of the positioning measurement process includes at least one of the following methods: base station transmission to UE reception, UE transmission to base station reception, UE self-transmission and reception, and transmission and reception between UEs. The fourth communication device sends the measurement results to the LMF (Local Management Function). The LMF calculates the UE location information based on the measurement results sent by the fourth communication device and sends it to the sensing network function / sensing network element through the AMF (Awareness Management Function).

[0102] Optionally, after obtaining the measurement result corresponding to the measured quantity, the method further includes:

[0103] Based on the measurement result corresponding to the first target measurement quantity and the positioning result sent by the third communication device, the perception result is determined. The first target measurement quantity includes at least one of the perception measurement quantity and the common measurement quantity. The positioning result is sent by the third communication device according to the positioning requirement, and the positioning result includes terminal location information.

[0104] Here, the positioning result sent by the third communication device can be the direct feedback from the third communication device based on the positioning request. For example, when the positioning request is used to request the acquisition of a known positioning result, the third communication device can directly feed back the known positioning result based on the positioning request, that is, the positioning result includes the known positioning result.

[0105] Alternatively, the aforementioned positioning result is obtained by a third communication device measuring the measurement quantity. For example, when the positioning request is used to request the current positioning result or the positioning result at a preset future time, the third communication device measures the measurement quantity to obtain the positioning result. Based on this, the method of this application embodiment, before determining the sensing result based on the measurement result corresponding to the first target measurement quantity and the positioning result sent by the third communication device, further includes:

[0108] In this implementation, the first communication device sends the target measurement result corresponding to the second target measurement quantity to the LMF. The LMF obtains the UE location information based on the target measurement result and sends it to the third communication device.

[0109] Optionally, the terminal location information includes first indication information, which is used to indicate the correspondence between the positioning result and the first target measurement.

This time can be a non-periodic time or a periodic time. Optionally, this time can be an absolute time, such as expressed in UTC; or a relative time, such as relative to a certain public time. Optionally, this time can be consistent with the time in the location request.

[0117] Optionally, the aforementioned sensing needs may further include the type of sensing needs, wherein the type of sensing needs includes at least one of the following:

[0118] The first perception demand type is used to request the acquisition of known perception results, for example, to request the acquisition of the last known perception result or to request the acquisition of the initially known perception result;

[0120] The third perception demand type is used to request the perception results at a future preset time.

[0121] The perception requirement also includes a second indication information, which is used to indicate the time corresponding to the perception result requested by the perception requirement.

[0122] The time here can be at least one of the following: start time, end time, duration, period, or number of periods. Optionally, this time can be a point in time or a time window. This time can be a non-periodic time or a periodic time. Optionally, this time can be an absolute time, such as expressed in UTC; or a relative time, such as relative to a certain public time. Optionally, this time can be consistent with the time in the location request.

[0123] Optionally, the sensing requirement may also include an indication of the positioning method, such as a positioning method based on time or angle, or a specific positioning method (such as DL-TDOA, DL-AOD, multi-RTT, etc.), and the third communication device determines the sensing result to be fed back based on the positioning method.

[0124] Optionally, the sensing requirements may also include the type of sensing feedback, such as immediate feedback, periodic feedback, or event-triggered feedback. Furthermore, the sensing requirements may include configuration information for the aforementioned feedback.

[0125] The sensing result in this application embodiment can be the measurement value corresponding to the measurement quantity, or it can be the result obtained after calculating and processing the measurement value corresponding to the measurement quantity.

[0126] The perception results in the embodiments of this application may include at least one of the following:

The factors considered in the selection include at least: the requested QoS (such as sensing accuracy, response time, sensing QoS level), access type (3GPP access / non-3GPP access), the target UE's AN type (such as 5G NR or eLTE) and the serving AN node (such as gNodeB or NG-eNodeB), RAN configuration information, sensing network function / sensing network element capabilities, sensing network function / sensing network element load, sensing network function / sensing network element location, indication of single event reporting or multiple event reporting, event reporting duration, network slicing information, etc.

[0152] A sensing network function / sensing element can be a new network element, or an existing network function / element such as LMF, but with added sensing-related functions.

[0153] Among them, the core network functions or network elements (such as sensing network functions / sensing network elements), application servers, or other nodes complete the regulatory process.

[0154] Step 303: AMF sends the environmental reconstruction sensing requirements to the sensing network elements.

[0155] Step 304: If the environment reconstruction perception requirement requires location service assistance, then select the base station and UE associated with the environment reconstruction perception requirement.

[0156] The method for selecting the base station and UE associated with the environmental reconstruction sensing requirements can be:

[0157] Select the base station and UE accessing the base station within the corresponding area based on the region and scope of the environmental reconstruction.

[0158] The base station or UE that initiates the environmental reconstruction perception requirement is associated with the base station or UE.

[0159] Step 305: Send the environment reconstruction awareness request to the associated base station and / or UE.

[0160] Step 306: Send the location request to AMF.

[0161] Step 307: AMF selects at least one LMF.

[0162] Step 308: AMF sends a location request to LMF.

[0163] The positioning requirements are derived from the environmental reconstruction perception requirements, and specifically include at least one of the following:

[0164] Determine the positioning accuracy / error requirements based on the environmental reconstruction accuracy / error requirements;

[0165] Determine the positioning delay requirement based on the environmental reconfiguration delay requirement;

[0166] In addition, the positioning requirement may include the associated base station and / or UE of the environment reconstruction perception requirement, which is used to assist the LMF in selecting the base station and / or UE associated with the environment reconstruction perception requirement.

[0167] Step 309: The LMF identifies the base station and / or UE associated with the location request and sends the location request to the associated base station and / or UE.

[0168] The method for selecting the base station and / or UE associated with the positioning requirement can be to select the corresponding base station and UE based on the base station and / or UE associated with the perception requirement.

[0169] Step 310: Determine the configuration information of the environmental reconstruction sensing signal based on the environmental reconstruction sensing requirements, and determine the configuration information of the positioning signal based on the positioning requirements.

[0170] Optionally, the configuration information of the environmental reconstruction sensing signal can be determined based on the environmental reconstruction sensing requirements and the positioning information obtained from the previous triggering of the positioning process:

[0171] Optionally, the sensing signal and the positioning signal use different reference signals, which can be uplink signals or downlink signals, or one uplink signal and the other downlink signal. The sensing network function / sensing network element determines the sensing signal configuration according to the environmental reconstruction sensing requirements, and the LMF determines the positioning signal configuration according to the positioning requirements.

[0172] Optionally, the sensing signal and the positioning signal use the same reference signal, which can be an uplink signal or a downlink signal, or one can be an uplink signal and the other a downlink signal;

[0173] Among them, the configuration information of the sensing signal and the configuration information of the positioning signal are determined by one of the sensing network function / sensing network element and LMF, and the corresponding signal configuration information is notified to the other through AMF;

[0174] Alternatively, the configuration information for the sensing signals and the positioning signals can be jointly determined. One approach is that, for a specific signal configuration, the one with higher requirements decides on that configuration. For example, if environmental reconstruction sensing needs a larger signal bandwidth than positioning, the signal bandwidth is determined by the sensing network function / sensing element based on the environmental reconstruction requirements. Specifically, one party, such as the LMF, can first determine the positioning signal configuration and then send it to the sensing network function / sensing element. The sensing network function / sensing element then supplements the sensing signal configuration and directly sends it to the associated base station and / or UE.

[0175] The configuration information of the sensing signal or positioning signal includes at least one of the following:

[0176] Waveforms, such as OFDM, SC-FDMA, OTFS, frequency modulated continuous wave (FMCW), pulse signals, etc.

[0177] Subcarrier spacing: For example, the subcarrier spacing of an OFDM system is 30 kHz;

[0178] Guard interval: The time interval between the end of signal transmission and the latest echo signal of that signal being received; this parameter is proportional to the maximum sensing distance; for example, it can be calculated by 2dmax / c, where dmax is the maximum sensing distance (related to sensing requirements). For example, for self-transmitting and self-receiving sensing signals, dmax represents the maximum distance from the sensing signal transmission point to the signal transmission point; in some cases, the OFDM signal cyclic prefix CP can serve as the minimum guard interval; c is the speed of light.

[0179] Bandwidth: This parameter is inversely proportional to the distance resolution and can be obtained by c / 2 / delta_d, where delta_d is the distance resolution (related to sensing requirements);

[0180] Burst duration: This parameter is inversely proportional to the rate resolution (related to sensing requirements). This parameter represents the time span of the sensed signal and is mainly used to calculate the Doppler frequency offset. This parameter can be calculated using c / 2 / delta_v / fc, where delta_v is the rate resolution and fc is the signal carrier frequency or the center frequency of the signal.

[0181] Time-domain interval: This parameter can be calculated using c / 2 / fc / v_range; where v_range is the maximum rate minus the minimum rate (related to sensing requirements); this parameter is the time interval between two adjacent sensing signals;

[0182] Transmitted signal power, for example, taking a value every 2dBm from -20dBm to 23dBm;

[0183] Signal formats, such as DMRS, CSI-RS, SRS, TRS, PT-RS, PRS, etc., can also be data signals, or newly defined sensing signals, or newly defined integrated communication and sensing signals, as well as related sequence format information;

[0184] Signal direction; for example, sensing the direction of a signal or beam information;

[0185] Time resources, such as the time slot index or symbol index of the time slot where the sensing signal is located; among them, time resources are divided into two types: one is one-time time resources, such as one symbol sending an omnidirectional first signal; the other is non-one-time time resources, such as multiple sets of periodic time resources or discontinuous time resources (which may include start and end times), each set of periodic time resources sends a sensing signal in the same direction, and the beam direction on different sets of periodic time resources is different.

[0186] Frequency resources include the center frequency of the sensing signal, bandwidth, RBs, or subcarriers, etc.

[0187] Quasi-co-located QCL relationships, such as sensing signals comprising multiple resources, each resource associated with an SSB QCL, the QCL including Type A, B, C, or D.

[0188] In particular, if the environment reconstruction sensing signal and the positioning signal are not the same reference signal, when determining the signal time resource configuration, it is necessary to limit the time interval between the environment reconstruction sensing reference signal and the positioning reference signal to be less than a certain range, such as less than X time units. The time unit can be TTI, slot, sub-slot, symbol, etc. The time interval is related to the environment reconstruction delay requirement, the positioning delay requirement, and the UE movement speed.

[0189] Step 311: The sensing network function / sensing network element and LMF respectively send the configuration information of the environment reconstruction sensing signal and the configuration information of the positioning signal to the associated base station and / or UE.

[0190] Specifically, if the same reference signal is used for environment reconstruction sensing and positioning, and the base station and / or UE requiring positioning is the same as the base station and / or UE requiring sensing, and the base station / UE performing the measurement process (sensing measurement process and positioning measurement process) is the same, then only one of the sensing network function / sensing element and LMF needs to send the configuration to the UE / base station. When using the same configuration, the signal configuration information includes identification information to indicate whether the signal is used for both positioning and sensing simultaneously (e.g., using a 1-bit information field; "0" indicates that it is not used for both positioning and sensing simultaneously, and "1" indicates that the signal is used for both positioning and sensing simultaneously).

[0191] Step 312: Determine the measurement quantities based on the environmental reconstruction perception requirements and positioning requirements.

[0192] The measured quantities include at least:

[0193] Common measurement quantities, which are the measurement quantities shared by sensing and positioning requirements, are determined by one of the sensing network functions / sensing elements and the LMF and the corresponding measurement quantity information is notified to the other through the AMF, or they are jointly determined.

[0194] Non-common measurements, namely the measurements for sensing requirements and localization requirements (localization measurements and environmental reconstruction measurements), are determined by the sensing network functions / sensing elements and LMF respectively.

[0195] Environmental reconfiguration measurements can be:

[0196] The reflection path delay, the delay difference between reflection paths, the distance of the reflection point relative to the UE / base station, the arrival and departure angles of the signal relative to the reflection point, the arrival and departure angles of the reflection path on the base station side, the arrival and departure angles of the reflection path on the UE side, the signal strength of the reflection path, the reflection order identifier of the reflection path (e.g., first-order reflection, multi-order reflection), relevant information of the UE's local coordinate system (e.g., UE orientation or UE antenna panel orientation, local coordinate origin, local coordinate x / y / z axis direction), the coordinates of the reflection point in the reference coordinate system based on the base station, the coordinates of the reflection point in the reference coordinate system based on the UE, and the coordinates of the reflection point in the global coordinate system (the global coordinate system can be a common reference coordinate system for multiple base stations or UEs).

[0197] Positioning measurements can be:

[0198] Direct path delay, reflected path delay, delay difference between reflected paths, first-arrival path delay (which may be a direct path or a reflected path), arrival and departure angles of the signal relative to the reflection point, arrival and departure angles of multipath signals on the base station side, arrival and departure angles of multipath signals on the UE side, direct path signal strength, reflected path signal strength, first-arrival path signal strength, reflection order identifier of the reflected path (e.g., first-order reflection, multi-order reflection), and the time or time difference between signals from different base stations arriving at the UE.

[0199] Common measurements can be:

[0200] Reflection path delay, delay difference between reflection paths, distance of reflection point relative to UE / base station, arrival and departure angles of signal relative to reflection point, arrival and departure angles of reflection path on base station side, arrival and departure angles of reflection path on UE side, signal strength of reflection path, and reflection order identifier of reflection path (e.g., first-order reflection, multi-order reflection).

[0201] Specifically, the measurement quantity may consist only of sensing measurement quantity and common measurement quantity, without positioning measurement quantity.

[0202] Step 313: The sensing network function / sensing element sends environmental reconstruction measurements and / or common measurements to the associated base station and / or UE; the LMF sends positioning measurements (if any) and / or common measurements to the associated base station and / or UE.

[0203] Specifically, the way in which the sensing network function / sensing element sends environmental reconstruction measurements and / or common measurements to the associated base station can be:

[0204] First it is sent to the AMF, and then the AMF sends it to the base station through the N2 interface;

[0205] It is sent directly to the base station through the newly defined interface.

[0206] The way that the sensing network function / sensing element sends environmental reconstruction measurements and / or common measurements to the associated UE can be:

[0207] First, it is sent to the AMF, then the AMF sends it to the base station through the N2 interface, and then the base station sends it through higher-layer signaling, MAC CE signaling, or Layer 1 signaling, such as DCI;

[0208] The data is sent directly to the base station via a newly defined interface, and then the base station sends it to the UE via higher-layer signaling, MAC CE signaling, or Layer 1 signaling (e.g., DCI).

[0209] Send to UE via NAS signaling.

[0210] The measurements can also be sent by one party to the associated base station and / or UE.

[0211] In this embodiment of the application, the associated base station and / or UE executes the environment reconstruction measurement process according to the environment reconstruction sensing signal configuration, sensing measurement quantity, and common measurement quantity. The method includes at least one of the following: base station self-transmission and self-reception, base station to-base station transmission and reception, base station to-UE reception, UE to-base station reception, UE self-transmission and self-reception, and UE to-UE transmission and reception.

[0212] The associated base station and / or UE execute the positioning process based on the positioning signal configuration, positioning measurement, and common measurement, and the method includes at least one of the following: base station transmits and UE receives, UE transmits and base station receives, UE transmits and receives on its own, and UEs transmit and receive each other.

[0213] Specifically, if the environment reconstruction and positioning use the same reference signal and the measurement quantities are the same, i.e. there are only environment reconstruction measurement quantities and common measurement quantities, and no positioning measurement quantities, and the base station and / or UE associated with the positioning requirement are the same as the base station and / or UE associated with the perception requirement, and the base station / UE performing the measurement process (perception measurement process and positioning measurement process) are the same, then only the environment reconstruction measurement process can be performed, and the environment reconstruction measurement method includes the positioning measurement method (i.e. UE participation in the measurement), such as at least one of base station transmission and UE reception, UE transmission and base station reception, UE self-transmission and self-reception, and UE-to-UE transmission and reception.

[0214] Step 314: The sensing associated base station and / or UE sends the measurement results corresponding to the environmental reconstruction measurement and / or common measurement to the sensing network function / sensing network element.

[0215] Step 315: The location association base station or UE sends the location measurement and / or common measurement to the LMF. The LMF calculates the UE location information and sends it to the sensing network function / sensing network element through the AMF.

[0216] Alternatively, the sensing network function / sensing element sends common measurements to the LMF through the AMF. The LMF calculates the UE location information and sends it to the sensing network function / sensing element through the AMF (for cases where there are only environmental reconstruction measurements and common measurements, but no positioning measurements). In particular, the UE location information includes information indicating the correspondence with the environmental reconstruction measurements and / or common measurements, such as time information, which can be absolute time, frame number, TTI sequence number, slot number, sub-slot number, symbol sequence number, etc. (the environmental reconstruction measurements and / or common measurements contain the same time information), or index information consistent with the environmental reconstruction measurements and / or common measurements. For example, if the UE measures the environmental reconstruction measurement as the coordinates of the reflection point at location 1, the index number of this coordinate is X. The UE location 1 information is obtained through the positioning process, and the index of this location information is also X.

[0217] Step 316: The sensing network function / sensing element calculates the sensing results based on the measurement results and UE location information.

[0218] The measurement results in this step specifically refer to the measurement results corresponding to environmental reconstruction measurements and / or common measurements.

[0219] The sensing and positioning method of this application embodiment receives a sensing request; when the sensing request is a sensing request associated with a positioning service, it sends the sensing request to a second communication device and a positioning request to a third communication device, thereby triggering a process of combining sensing and positioning, and thus achieving the purpose of sensing by combining positioning information.
