[0002] This disclosure claims priority to Chinese Patent Application No. 202510187588.4, filed on February 20, 2025, entitled “A Communication Sensing Method, Sensing Control Network Element, Sensing Node and Storage Medium”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of communication technology, specifically to a communication sensing method, a sensing control network element, a sensing node, and a storage medium. Background Technology

[0004] Integrated Sensing and Communication (ISAC) introduces wireless sensing capabilities into wireless mobile communication. The principle of wireless sensing is to transmit wireless signals to the environment to be sensed, while simultaneously collecting the reflected, scattered, or multipath-transmitted wireless signals at the receiving end. Because the collected wireless signals are influenced by the environment, environmental information can be obtained by processing these signals, thus achieving environmental sensing.

[0005] If the sensing and control functions are fully deployed on the core network (CN) side, since the CN does not concern itself with the network elements and radio resources within the radio access network (RAN), the implementation of sensing and control functions related to the selection of sensing nodes and the coordination of their resource configuration will be quite difficult. If the sensing and control functions are fully deployed on the RAN side, since the RAN network elements are only connected to a small number of nearby base stations, it will be difficult to achieve significant sensing coverage.

[0088] To better understand the above-described objectives, features, and advantages of this disclosure, the present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It is to be understood that the described embodiments are only some, not all, of the embodiments of this disclosure. The specific embodiments described herein are merely for explaining this disclosure and are not intended to limit it. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure are within the scope of protection of this disclosure.

[0089] It should be noted that in this article, relational terms such as “first” and “second” are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0090] With the rapid development of mobile communication technology, the air interface transmission capabilities of mobile communication systems are constantly being strengthened, enabling services to extend into vertical industries. 5G-A (5G-Advanced, an evolution of 5G technology) will expand into deeper areas of vertical industries, from supporting the Internet of Things to enabling the intelligent interconnection of everything, creating value for social development and industry upgrading. Sensing services will be a crucial supporting capability for realizing future intelligent network upgrades and expanding industry applications, making the integration of communication and sensing a key evolutionary direction for 5G-A and 6G.

[0091] Typically, sensing systems and communication systems have different functions and exist independently. Sensing systems primarily acquire information about the surrounding environment or objects to achieve purposes such as localization and tracking. Traditional sensing technologies mainly rely on radio waves, radar, infrared radiation, and sensors. For example, radar is an electronic device that uses electromagnetic waves to detect targets. Radar emits electromagnetic waves to illuminate the target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the rate of change of distance (radial velocity), azimuth, and altitude. Communication systems, on the other hand, mainly rely on the propagation of electromagnetic waves in free space to ensure the transmission of communication data.

[0092] Communication-Sensing Convergence (ISAC) is based on the coexistence or sharing of hardware, software, and spectrum resources on a single network to simultaneously realize wireless sensing and wireless communication functions. In 5G-A and 6G, ISAC aims to leverage mobile communication infrastructure to enable sensing services, achieving multi-functionality within a single network. It fully utilizes the advantages of mobile networks to meet the sensing performance requirements of different scenarios, while simultaneously improving communication performance through sensing services. On one hand, it utilizes communication systems to measure sensing dimensions, reduce the cost of sensing hardware deployment, and effectively expand the sensing range by leveraging the advantages of seamless network coverage. On the other hand, it further innovates wireless communication resource management and improves the performance of wireless communication systems based on the perception, identification, and prediction of the wireless communication channel environment.

[0093] At least one embodiment of this disclosure provides a communication sensing method, a sensing control network element, a sensing node, or a storage medium. After receiving a sensing task request, the first sensing control network element of the core network (CN) selects a second sensing control network element of the access network (RAN) for cooperative sensing control and sends sensing control information to the second sensing control element of the RAN. This enables the first sensing control network element of the CN to cooperate with the second sensing control network element of the RAN for sensing control. Compared with related technologies that deploy the sensing control function entirely on the CN or RAN side, the embodiments of this disclosure can improve the sensing control capability.

[0094] Figure 1 is a flowchart illustrating a communication sensing method provided in an embodiment of this disclosure. This communication sensing method is applied to a first sensing control network element in the core network (CN). The first sensing control network element is a network element in the core network that has sensing and control functions. The first sensing control network element can be a related network element in the core network, an independent network element in the core network, or it can be co-located (i.e., merged) with related network elements in the core network. As shown in Figure 1, the method may include, but is not limited to, steps 101 to 103:

[0095] In step 101, a sensing task request is received from the sensing service requester.

[0096] The requester of the sensing service is the network element or terminal (e.g., User Equipment (UE) or User Terminal (UT)) that needs to perform the sensing task. The sensing task request includes a sensing task identifier.

[0097] One example of a sensing task is intrusion target detection, where the intrusion target is a device that is not communicating with the communication system and is to be detected, located, or tracked. Because the intrusion target is not communicating with the communication system, the sensing system is unaware of its existence. Sensing nodes (i.e., sensing receivers) estimate the position, velocity, and orientation of the intrusion target by receiving sensing signals reflected and / or scattered by the target.

[0098] In a collaborative sensing scenario, a sensing transmitting device sends sensing signals, and at least one sensing receiving device receives the sensing signals. The sensing transmitting device is the transmitting node of the sensing signals, and can be a base station (BS) or a terminal (e.g., user equipment (UE) or user terminal (UT)). The sensing receiving device is the receiving node of the sensing signals, and can be a base station (BS) or a terminal (e.g., user equipment (UE) or user terminal (UT)).

[0099] In step 102, a second sensing control network element of the access network is selected for cooperative sensing control.

[0100] The second sensing and control network element in the access network (RAN) is a network element in the RAN that has sensing and control functions (e.g., a base station with sensing and control functions). The second sensing and control network element can be a related network element in the RAN, an independent network element in the RAN, or it can be co-located with related network elements in the RAN.

[0101] In this embodiment, the first sensing control network element of the core network (CN) selects the second sensing control network element of the access network (RAN) for cooperative sensing control, so that the first sensing control network element of the core network (CN) can cooperate with the second sensing control network element of the access network (RAN) for sensing control.

[0102] In step 103, sensing control information is sent to the second sensing control network element, and the sensing control information includes at least one of the following (1) to (3):

[0103] (1) Perceive task identifiers.

[0104] The sensing task identifier can be the sensing task identifier carried in the sensing task request, or it can be the sensing task identifier generated by the first sensing control network element of the core network (CN) after receiving the sensing task request.

[0105] (2) Sensing parameters.

[0106] The perception parameters are related to the object to be perceived and may include at least one of the following:

[0107] Distance, rate of change of distance (radial velocity), velocity, azimuth, altitude.

[0108] (3) Perception accuracy.

[0109] Perception accuracy represents the error between the measured value and the true value, reflecting the accuracy of the perception result. Perception accuracy may include at least one of the following:

[0110] Distance accuracy, distance change rate (radial velocity) accuracy, velocity accuracy, azimuth accuracy, and altitude accuracy.

[0111] In some embodiments, the first sensing control network element of the CN can also formulate sensing decision information and send the sensing decision information to the second sensing control network element of the RAN. The sensing decision information includes, for example, sensing task parameters, which may include at least one of the following: sensing measurement frequency and data reporting frequency. The first sensing control network element of the CN can configure the sensing task parameters based on sensing Quality of Service (QoS) requirements.

[0112] It is evident that, compared to related technologies where the sensing and control functions are fully deployed on the CN or RAN side, there is a problem of weak sensing and control capabilities. In this embodiment, after receiving the sensing task request, the first sensing and control network element of the core network (CN) selects the second sensing and control network element of the access network (RAN) to cooperate in sensing and control, and sends sensing and control information to the second sensing and control network element of the RAN. This enables the first sensing and control network element of the CN to cooperate with the second sensing and control network element of the RAN in sensing and control, thereby improving the sensing and control capabilities.

[0113] In some embodiments, after the first sensing control network element of the CN sends sensing control information to the second sensing control network element of the RAN, the first sensing control network element of the CN can also receive sensing data sent by the second sensing control network element of the RAN and generate sensing results based on the sensing data; thereby, the first sensing control network element of the CN sends a sensing task response to the sensing service requester, and the sensing task response includes the sensing results.

[0114] Among them, the perception task response is the response corresponding to the perception task request sent by the perception service requester.

[0115] As can be seen, in this embodiment, the perception control function of the first perception control network element of the CN includes: receiving the perception task request sent by the perception service requester, selecting the second perception control network element of the RAN, formulating perception decision information, and generating perception results (for example, if the perception task request is an intrusion detection request, then the perception result is whether an intrusion target exists).

[0116] The sensing control functions of the second sensing control network element of the RAN used for collaborative sensing control include: selecting sensing nodes (i.e., selecting devices to perform sensing), coordinating and allocating sensing resources, and processing sensing data.

[0117] Among them, the sensing node can be a RAN network element with sensing function (such as a base station) or a terminal (such as a user equipment (UE) or user terminal (UT)).

[0118] The sensing resources include frequency domain resources and / or time domain resources. Frequency domain resources can be pre-allocated sensing frequency resources in units of resource elements (REs) or resource blocks (RBs). Time domain resources can be pre-allocated sensing time domain resources in units of orthogonal frequency division multiplexing (OFDM) symbol length or time slot length.

[0119] The perceived data includes at least one of the following:

[0120] Raw sensory information, preliminary sensory information, and measurement information.

[0121] The raw sensing information includes, for example, the Channel Impulse Response (CIR). Preliminary sensing information includes, for example, at least one of the Time of Arrival (TOA) spectrum and the Doppler map. Measurement information includes, for example, at least one of the Time of Arrival, Angle of Arrival (AOA), velocity, and Doppler measurements.

[0122] Figure 2 is a flowchart illustrating another communication sensing method provided in this embodiment of the present disclosure. This communication sensing method is applied to a second sensing control network element in an access network (RAN). The second sensing control network element in the access network (RAN) is a network element in the RAN with sensing control functions (e.g., a base station with sensing control functions). The second sensing control network element can be a related network element in the RAN, an independent network element in the RAN, or it can be co-located with related network elements in the RAN. As shown in Figure 2, the method may include, but is not limited to, steps 201 and 202:

[0123] In step 201, sensing control information is received from the first sensing control network element of the core network used for cooperative sensing control.

[0124] In this embodiment, the second sensing control network element of the RAN receives sensing control information sent by the first sensing control network element of the CN. The sensing control information includes at least one of the following (1) to (3):

[0127] (2) Sensing parameters.

[0128] Perception parameters may include at least one of the following:

[0129] Distance, rate of change of distance (radial velocity), velocity, azimuth, altitude.

[0130] (3) Perception accuracy.

[0131] Perception accuracy represents the error between the measured value and the true value, reflecting the accuracy of the perception result. Perception accuracy may include at least one of the following:

[0132] Distance accuracy, distance change rate (radial velocity) accuracy, velocity accuracy, azimuth accuracy, and altitude accuracy.

[0133] In some embodiments, the second sensing control network element of the RAN can also receive sensing decision information sent by the first sensing control network element of the CN. This sensing decision information includes, for example, sensing task parameters, which include at least one of the following: sensing measurement frequency, data reporting frequency, etc.

[0134] In step 202, a sensing node of the access network is selected to receive and / or transmit sensing signals.

[0135] Among them, the sensing node can be a sensing transmitting device (i.e., the transmitting node of the sensing signal) or a sensing receiving device (i.e., the receiving node of the sensing signal).

[0136] In this embodiment, the second sensing control network element of the RAN selects the sensing node of the RAN, that is, selects the RAN network element that can perform sensing. For example, the second sensing control network element of the RAN selects a base station with sensing function as the sensing node of the RAN.

[0137] In some embodiments, in step 202, selecting a sensing node in the access network to receive and / or transmit sensing signals includes the following (1) and (2):

[0138] (1) Receive air interface sensing resource information sent by at least one sensing node of the access network.

[0139] In this embodiment, if there is only one sensing node in the access network, the second sensing control network element of the RAN can receive the air interface sensing resource information sent by that sensing node. If there are multiple sensing nodes in the access network, the second sensing control network element of the RAN can receive the air interface sensing resource information sent by each sensing node.

[0140] The air interface sensing resource information includes at least one of the following A to D:

[0145] The sensing resources may include frequency domain resources and / or time domain resources. Frequency domain resources may be pre-allocated sensing frequency resources in units of resource elements (REs) or resource blocks (RBs). Time domain resources may be pre-allocated sensing time domain resources in units of orthogonal frequency division multiplexing (OFDM) symbol length or time slot length.

[0146] C. Terminal information that can be sensed under the coverage of sensing nodes.

[0147] The sensing node can be a sensing node of the RAN (e.g., a base station with sensing capabilities), and the terminal that can perform sensing can be a user equipment (UE) or a user terminal (UT). The terminal information that can perform sensing includes the terminal's location information.

[0148] D. Information on sensing nodes in the access network near the sensing node.

[0149] Here, "nearby" can be understood as being able to communicate directly with the sensing node, or it can be understood as being within the preset range of the sensing node.

[0150] (2) Based on the air interface sensing resource information sent by at least one sensing node of the access network, select a sensing node of the access network to receive and / or send sensing signals.

[0151] In this embodiment, the second sensing control network element of the RAN can select sensing nodes of the RAN that meet preset conditions to receive and / or transmit sensing signals based on air interface sensing resource information sent by at least one sensing node of the RAN. The preset conditions may include at least one of the following:

[0152] It supports specific sensing signal types, terminals with abundant sensing resources and coverage that can perform sensing, and sensing nodes with a large number of RAN nodes nearby.

[0153] In some embodiments, the second sensing control network element of the RAN can also send sensing configuration information to the selected sensing nodes of the RAN.

[0154] In this embodiment, the second sensing control network element of the RAN sends sensing configuration information to the sensing nodes of the RAN through the network interface between base stations or the OAM (Operation, Administration and Maintenance) system.

[0155] The perception configuration information includes at least one of the following (1) to (4):

[0159] The perception mode can be either monobasic perception or bibasic perception.

[0160] Single-base sensing refers to a single node transmitting a sensing signal and receiving the echo. Single-base sensing includes single-base station sensing or single-terminal sensing. Single-base station sensing involves the base station transmitting a sensing signal, which is then reflected and / or scattered by the sensing object, and the base station receiving the reflected and / or scattered sensing signal.

[0167] If the selected sensing node is a sensing transmitting device in a two-base sensing mode, then the devices cooperating in sensing are sensing receiving devices in the two-base sensing mode. If the selected sensing node is a sensing receiving device in a two-base sensing mode, then the devices cooperating in sensing are sensing transmitting devices in the two-base sensing mode.

[0168] In some embodiments, the second sensing control network element of the RAN can also receive sensing data sent by the selected sensing nodes of the RAN, process the sensing data, and send it to the first sensing control network element of the CN.

[0169] The perceived data includes at least one of the following:

The measurement information includes, for example, at least one of the time of arrival, angle of arrival (AOA), velocity, and Doppler measurements.

[0172] In this embodiment, the sensing control functions of the second sensing control network element of the RAN include: selecting sensing nodes (i.e., selecting devices to perform sensing), coordinating and allocating sensing resources, and processing sensing data.

[0173] Figure 3 is a flowchart illustrating another communication sensing method provided in this embodiment of the present disclosure. This communication sensing method is applied to a sensing node in an access network (RAN). The RAN sensing node is a RAN network element capable of performing sensing (e.g., a base station with sensing functionality).
