[0223] The terminology used in the embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of this disclosure.

[0224] In this embodiment of the disclosure, unless otherwise stated, elements expressed in the singular form, such as "a," "an," "the," "the," "the," "the," "the," "the," "this," etc., can mean "one and only one," or "one or more," "at least one," etc. For example, when using articles such as "a," "an," "the," etc. in translation, the noun following the article can be understood as either a singular expression or a plural expression.

[0226] In some embodiments, the terms “at least one of”, “at least one of”, “at least one of”, “one or more”, “a plurality of”, “multiple”, etc., may be used interchangeably.

[0227] The descriptions in this disclosure, such as "at least one of A, B, C..." or "A and / or B and / or C...", include the case where any one of A, B, C... exists alone, as well as the case where any combination of any of A, B, C... exists alone. Each case can exist alone. For example, "at least one of A, B, C" includes the cases of A alone, B alone, C alone, A and B combination, A and C combination, B and C combination, and A and B and C combination. For example, A and / or B includes the cases of A alone, B alone, and A and B combination.

[0229] The prefixes "first," "second," etc., used in the embodiments of this disclosure are merely for distinguishing different descriptive objects and do not impose restrictions on the position, order, priority, quantity, or content of the descriptive objects. The description of the descriptive objects is found in the claims or the context of the embodiments, and the use of prefixes should not constitute unnecessary restrictions. For example, if the descriptive object is a "field," the ordinal numbers preceding "field" in "first field" and "second field" do not restrict the position or order of the "fields." "First" and "second" do not restrict whether the "fields" they modify are in the same message, nor do they restrict the order of "first field" and "second field." Similarly, if the descriptive object is a "level," the ordinal numbers preceding "level" in "first level" and "second level" do not restrict the priority between "levels." Furthermore, the number of descriptive objects is not limited by ordinal numbers and can be one or more. For example, in "first device," the number of "devices" can be one or more. Furthermore, the objects modified by different prefixes can be the same or different. For example, if the object being described is "device", then "first device" and "second device" can be the same device or different devices, and their types can be the same or different. As another example, if the object being described is "information", then "first configuration" and "second configuration" can be the same information or different information, and their content can be the same or different.

[0260] The convergence of communication and sensing in 5G systems specified by 3GPP (3rd Generation Partnership Project) mainly explores the use of wireless channel characteristics to obtain richer environmental information and realize basic sensing applications based on the 5G basic network architecture and air interface enhancement design.

[0261] In the field of mobile communications, the development of communication sensing convergence is mainly in its initial stage. In the current 5G-A phase, the main focus is on exploring the use of wireless channel characteristics based on the 5G basic network architecture and air interface enhancement design to obtain richer environmental information and realize basic sensing applications.

[0262] Sensing technology utilizes wireless signals to perceive targets or states in the surrounding environment. Wireless terminals or base stations collect information such as signal strength, time delay phase changes, and Doppler shift, and after processing, output results such as target size, location, and speed. During this process, the network needs to trigger, modify, or terminate the sensing process, schedule wireless resources, process data, and release results according to service requirements.

[0263] A wireless signal transmitter emits radio waves, and a wireless signal receiver receives them. During the transmission of radio waves, the transmission may be blocked by objects (hereinafter referred to as reflectors), resulting in wireless transmission effects such as reflection, diffraction, transmission, phase change, Doppler shift, and signal intensity variation. The wireless signal receiver receives the radio waves and compares the transmitted and received signals, or records the historical changes in the received signal, thereby obtaining information about the reflector. This information (or, sensed information, or, sensed data) may include:

[0264] Coordinate information (e.g., coordinates relative to the wireless signal receiver (e.g., distance, horizontal angle, and vertical angle));

[0265] Speed ​​information (e.g., moving speed and direction of movement relative to the wireless signal receiver);

[0266] Behavioral pattern information (e.g., running, walking, approaching, falling, swinging, etc.); or weather information (e.g., rain, snow, etc.); or traffic information (e.g., congestion, accidents, etc.).

[0267] In a wireless network (e.g., a cellular network), the wireless signal transmitter can be at least one of the following:

[0268] Base station;

[0269] Wireless access points (e.g., WiFi access points (APs));

[0270] terminal.

[0271] The wireless signal receiver can be at least one of the following:

[0272] Base station;

[0273] Wireless access point;

[0274] terminal.

[0275] In discussing synesthesia technology, we consider introducing sensing network elements, which can have the following functions:

[0276] How to perform OoS (Quality of Service) parameter conversion for sensing services: To meet the OoS requirements of sensing services, QoS parameter conversion is necessary. This involves transmitting information such as the sensing service type or identifier, OoS requirements, sensing measurement data, and reporting cycle to the terminal or base station performing the sensing. If sensing requirements change, such as changes in the sensing area, data reporting time, or QoS requirements, the terminal or application needs to trigger the corresponding modification process.

[0277] How to trigger the perception service;

[0278] How to terminate the sensing service;

[0279] How to control base stations or terminals to perform sensing based on sensing service requirements:

[0280] How to efficiently process sensor measurement data;

[0281] How to provide or open up the perception results.

[0282] In this embodiment of the communication sensing technology, the main scenarios involve sensing nodes and sensing targets. The sensing target can be an object to be sensed, such as a vehicle, building, drone, or rainfall. The sensing node is a node that needs to sense the sensing target by sending and / or receiving sensing signals. Examples include base stations, user equipment, and vehicle-mounted equipment. The sensing node wants to sense information such as the distance and position of the sensing target from itself, including distance, angle, and speed of movement.

[0283] In this embodiment of the disclosure, the sensing network element and the access network element (RAN) can communicate in one of the following ways:

[0284] Method 1: SF can communicate with RAN (including control plane and data plane) through the core network AMF.

[0285] As shown in Figure 1b, the SF can communicate with the AMF via the NS1 interface or with the UPF via the NS7 interface. The AMF can communicate with the UE via the N1 interface, and with the RAN via the N2 interface; the RAN communicates with the UPF. The AMF can communicate with the UDM (Unified Data Management) via the N8 interface, and with the SF via the NS3 interface. The SF can communicate with the NWDAF (Network Data Analytics Function) via the NS4 interface, and with the LMF (Location Management Function) via the NS6 interface. The SF can communicate with the PCF via the NS5 interface and with the NEF (Network Exposure Function) via the NS2 interface. The AF (Application Function) can communicate with the NEF via the N33 interface, and the NEF can communicate with the PCF via the N5 interface.

[0286] Method 2: For the control plane and data plane separation architecture, SF interacts with RAN for control plane data through the core network AMF, and SF interacts with RAN for data plane data through UPF.

[0287] As shown in Figure 1c, the SF plane comprises SF-C (SF Control Plane) and SF-U (SF User Plane). SF-C communicates with the AMF via the NS1 interface, and SF-U communicates with the UPF via the NS7 interface. The AMF communicates with the UE via the N1 interface and with the RAN via the N2 interface; the RAN communicates with the UPF. The AME communicates with the UDM (Unified Data Management) via the N8 interface and with the SF-C via the NS3 interface. The SF-C communicates with the NWDAF (Network Data Analytics Function) via the NS4 interface and with the LMF (Location Management Function) via the NS6 interface. The SF-C communicates with the PCF via the NS5 interface and with the NEF (Network Exposure Function) via the NS2 interface. The AF (Application Function) communicates with the NEF via the N33 interface, and the NEF communicates with the PCF via the N5 interface.

[0288] Method 3: SF communicates directly with RAN (without going through the core network).

[0289] As shown in Figure 1d, the SF can communicate directly with the RAN via the NS1 interface, and with the AMF via the NS2 interface. The RAN can communicate with the AMF via the N2 interface, and with the UE via the Uu interface. The SF can communicate with the NWDAF (Network Data Analytics Function) via the NS4 interface, and with the NEF (Network Exposure Function) via the NS3 interface. The AF (Application Function) can communicate with the NEF via the N33 interface.

[0290] In this disclosure, the sensing network element can interact with the UE through access network equipment (e.g., base station) or AMF.

[0291] In this disclosure, the SF can exchange information with the UE through the RAN. Based on the different ways in which the SF and the RAN exchange information, there are also corresponding ways in which the SF and the UE exchange information.

[0292] This disclosure does not limit the specific communication methods between the sensing network element and the RAN, or between the SF and the UE.

[0293] This disclosure does not limit the specific communication methods between the sensing network element and the base station, or between the SF and the UE.

[0294] In this embodiment of the disclosure, the wireless signal transmitter and the wireless signal receiver can be from the same device (mono-static, same station) or different devices (bi-static / multi-static, dual station or multiple stations). Therefore, the sensing modes for sensing the target can include the following six modes. The corresponding sensing nodes are also different in different modes.

[0295] In this embodiment of the disclosure, the sensing nodes are access network devices (such as base stations) and include sensing mode 1 and sensing mode 2.

[0296] In Sensing Mode 1, the access network equipment performs self-transmission and self-reception. For example, the gNB sends a sensing signal, which is reflected after reaching the sensing target, and the gNB also receives the reflected sensing signal. This can also be called Sensing Method 1, as shown in Figure 1e, where base station A transmits and base station A receives.

[0297] Sensing mode 2 involves the transmission of sensing signals between different access network devices. For example, gNB A sends a sensing signal, and gNB B receives it. Alternatively, gNB A sends a sensing signal, which is reflected after reaching the sensing target, and then gNB B receives the reflected signal. This can also be called sensing method 2, as shown in Figure 1f, where base station A sends and base station B receives.

[0298] In this embodiment of the disclosure, the sensing nodes are between terminals, including sensing mode 3 and sensing mode 4.

[0299] In sensing mode 3, the terminal performs self-transmission and self-reception. For example, the UE sends a sensing signal, which is reflected after reaching the sensing target, and the UE also receives the reflected sensing signal. This can also be called sensing method 3, as shown in Figure 1g, where terminal A sends and terminal A receives.

[0300] Sensing mode 4 involves the transmission of sensing signals between different terminals. For example, UE A sends a sensing signal, and UE B receives the sensing signal. In another scenario, UE A sends a sensing signal, which is reflected after reaching the sensing target, and then UE B receives the reflected sensing signal. This can also be called sensing method 4, as shown in Figure 1h, where terminal A sends and terminal B receives.

[0301] In this embodiment of the disclosure, the sensing node is between the access network device and the terminal, including sensing mode 5 and sensing mode 6.

[0302] In sensing mode 5, the UE sends a sensing signal, and the gNB receives the sensing signal. For example, the UE sends a sensing signal, which is reflected after reaching the sensing target, and then the gNB receives the reflected sensing signal. This can also be called sensing method 5, as shown in Figure 1i, where terminal A sends and base station A receives.

[0303] Sensing mode 6 involves the gNB transmitting a sensing signal, which the UE receives. For example, the gNB transmits a sensing signal, the UE receives it, or the gNB transmits a sensing signal, the signal is reflected after reaching the sensing target, and then the UE receives the reflected signal. This can also be called sensing method 6, as shown in Figure 1j, where base station A transmits and terminal A receives.

[0304] The concept of sensing area is involved in the discussion of sensor integration, but there is no clear method for managing sensing area, such as the definition and configuration of sensing area. Therefore, this disclosure proposes a sensing area management method, including sensing area based on business needs and sensing area based on sensing node capabilities.

[0382] S202. The first node performs sensing services based on the first sensing area.

[0383] In some embodiments, the first node can be a first terminal, in which case the first terminal can perform sensing services within the first sensing area, such as sensing targets within the first sensing area.

[0384] For example, the first sensing area includes a sensing area based on business needs. Suppose that the type of the sensing target associated with the sensing area based on business needs is vehicle A, then the first terminal can sense vehicle A in the first sensing area (in this case, the first terminal may not be in the first sensing area); or, if the first terminal is in the first sensing area, then it senses vehicle A (in this case, vehicle A may not be in the first sensing area); or, if the first terminal is in the first sensing area, then it senses vehicle A in the first sensing area.

[0385] For example, the first sensing area includes a sensing area based on business needs and a sensing area supported by the second node. Assume that the second node is the second terminal, the sensing area supported by the second terminal is sensing area #1, the sensing area based on business needs is sensing area #2, and the first sensing area can be area #3 covered by the intersection of sensing area #1 and sensing area #2. Then, the first terminal can sense the target in area #3.

[0386] In some embodiments, the first node can be an access network device, in which case the access network device can perform sensing services within the first sensing area, such as sensing targets within the first sensing area.

[0387] Based on the above embodiments, the embodiments of this disclosure may further include:

[0388] S203, The first node stops sensing services.

[0389] In some embodiments, sensing services are stopped based on the sensing area supported by the second node and the sensing area based on business needs.

[0390] In some embodiments, the first node can be a first terminal, and the second node can be an access network device. Optionally, the first terminal can report its sensing area capabilities to the access network device, and the access network device selects a second terminal to perform sensing based on the sensing area capabilities reported by the first terminal. The second terminal can be at least one terminal, and the second terminal may include the first terminal.

[0391] In some embodiments, the first node can be a first terminal, and the first terminal and the second terminal can be the same terminal.

[0392] Optionally, the sensing area supported by the sensing area capability of the second terminal is the same as the sensing area supported by the first terminal; or, the sensing area supported by the sensing area capability of the second terminal can cover the sensing area supported by the first terminal; or, the sensing area supported by the sensing area capability of the second terminal can be covered by the sensing area supported by the first terminal.

[0393] In some embodiments, step S203 may include: if the sensing area supported by the second node does not overlap with the sensing area based on business needs, then the sensing service is stopped.

[0394] For example, if the second node is a terminal (UE), as shown in Figure 5b, after the UE moves, at time t3, the sensing area 2 supported by the UE and the sensing area 1 based on service requirements no longer overlap, so the UE stops sensing.

[0395] In some embodiments, the first node is a first terminal and the second node is a second terminal. Then step S203 may include: if the location of the first terminal after cell handover or cell reselection exceeds the sensing area based on service requirements, and the distance between the locations of the first terminal before and after cell handover or cell reselection exceeds the sensing area supported by the second terminal, then the sensing service is stopped.

[0396] For example, assuming the sensing area based on service requirements is PCI#1, and the UE is in PCI#2 after cell handover or cell reselection, and the distance between the UE's position before handover and its position after handover is greater than the sensing area #1 supported by the UE, then the UE stops sensing services.

[0397] In this embodiment of the disclosure, "perception" can also be understood as at least one of the following meanings: positioning, ranging, speed measurement, angle measurement, target imaging, target detection, target tracking, and target recognition.

[0643] This disclosure also provides an alternative implementation, a sensing area based on business needs and a sensing area based on sensing node capabilities, and a method for determining whether to stop sensing services by combining the two sensing areas.

[0644] In some embodiments, the sensing area may include: a sensing area based on business needs, and / or a sensing area based on the capabilities of sensing nodes.

[0645] Optionally, a perception area based on business needs represents the target area that needs to be perceived. For example, if the target needs to be perceived is a factory, a room, or a highway, then the factory, room, and highway are the perception areas.

[0646] In some embodiments, the sensing area can be determined in the following ways:

[0647] Geographic region, for example: describing a geographic region corresponding to a circle or polygon using coordinates; another example: reference point + radius, or multiple reference points;

[0648] Cell identifiers, such as PCI, CGI;

[0649] The location relative to a certain node, such as the location relative to the base station or the location relative to the terminal.

[0650] In some embodiments, the sensing area can be configured in the following ways:

[0651] Sensing network elements are configured for base stations;

[0652] The sensing network elements are configured for the terminal;

[0653] The base station is configured for the terminal.

[0654] In some embodiments, the sensing area based on the sensing node capability means that the sensing area is a capability of the sensing node, including: a sensing area supported by the base station, or a sensing area supported by the terminal.

[0655] In some embodiments, the sensing area supported by the base station, or the sensing area supported by the terminal, is associated with at least one of the following factors:

[0656] Tx's transmit power;

[0657] The sensitivity of Rx;

[0658] The reflective area of ​​the target;

[0659] Radar Cross Section (RCS);

[0660] The type of target, for example: for the same transmitted signal, a car has a stronger reflective ability than a person (or the type of target can be distinguished by RCS);

[0661] Sensing accuracy includes: position accuracy and velocity accuracy;

[0662] Perception resolution includes: position resolution and velocity resolution;

[0663] Perceive the false negative rate.

[0664] In some embodiments, the sensing region supported by the sensing region capability is the sensing region supported under the influence of factors.

[0665] For example: Sensing area 1 is associated with Tx transmit power and Target type (i.e., sensing area 1 is a sensing area that meets the requirements of Tx transmit power and Target type); sensing area 2 is associated with Tx transmit power, Target type, and resolution (i.e., sensing area 1 is a sensing area that meets the requirements of Tx transmit power, Target type, and resolution).

[0666] In some embodiments, the gNB (which may correspond to the first node mentioned above) sends its sensing area capability to the SF (which may correspond to the second node mentioned above).

[0667] In some embodiments, the UE (which may correspond to the first node mentioned above) sends its sensing area capabilities to the gNB and / or SF (which may correspond to the second node mentioned above).

[0668] In some embodiments, the gNB (which may correspond to the first node mentioned above) senses targets within the sensing area.

[0669] In some embodiments, the UE (which may correspond to the first node mentioned above) perceives targets within the perception area.

[0670] In some embodiments, the sensing area based on service requirements is sent to the base station or terminal as auxiliary information. Optionally, the sensing area based on service requirements can serve as auxiliary information to help the base station or terminal determine whether to perform sensing services. For example, when performing sensing, the base station or terminal can perform sensing services within the sensing area based on service requirements, or determine whether to stop the ongoing sensing service.

[0671] In some embodiments, the sensing area based on business needs is associated with the type of sensing target.

[0672] In some embodiments, the sensing area supported by the terminal or base station can be represented in the following ways:

[0673] Geographic region, such as an area defined by coordinates, such as a circular or polygonal region;

[0674] An area that uses a base station or terminal as a reference point, for example, a circular area with the location of the base station or terminal as the center and a certain distance as the radius.

[0675] In some embodiments, the terminal (UE) stops sensing services based on the aforementioned service-based sensing area and its sensing area capabilities.

[0676] In some embodiments, when a UE performs sensing, it stops sensing if its supported sensing area does not overlap with the configured service-based sensing area.

[0677] Optionally, the UE stops sensing when the sensing area 1 based on service requirements does not overlap with the sensing area 2 supported by the UE's sensing area capabilities. For example, as shown in Figure 5b, after the UE moves, at time t3, the sensing area 2 supported by the UE and the sensing area 1 based on service requirements no longer overlap, so the UE stops sensing.

[0678] In some embodiments, if the sensing area based on service requirements is represented by network coverage, such as PCI or CGI, and the UE determines the location to be location 1 when performing cell handover or cell reselection, the UE stops sensing services when the distance between the UE's location and location 1 is greater than the sensing area supported by the UE.

For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods.
