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. Similarly, if the object being described is "information", then "first information" and "second information" can be the same information or different information, and their content can be the same or different.

[0145] In some embodiments, the communication system 100 described above can be a sensing network system. In one example, the sensing network system can be an ISAC system.

[0146] In some embodiments, the first node 101 is used to configure a sensing reference signal for the sensing transmitting node 102 and the sensing receiving node 103. The configured sensing reference signal can be used to detect the object under test or to track the object under test.

[0147] In some embodiments, the first node is used to provide sensing functionality. In one example, the first node may be referred to as a sensing function (SF), a sensing function node, a sensing function entity, a sensing function network element, etc.

[0148] In some embodiments, the first node can be a terminal or a network device. In some embodiments, the first node can also be referred to as a sensing device. In one example, the first node is a server in a sensing network, and can also be referred to as a sensing server.

[0149] In some embodiments, the sensing transmitting node 102 is used to transmit a sensing reference signal (sensing RS). In some embodiments, the sensing reference signal can be understood as a reference signal used for sensing.

[0150] In some embodiments, the sensing receiving node 103 is used to receive a sensing reference signal and measure the sensing reference signal to detect the object under test. In some embodiments, the sensing receiving node 103 is used to send the detection result of the object under test to a first node 101 so that the first node 101 can configure resources for the object under test.

[0151] In some embodiments, the sensing reference signal may be reflected or scattered by the object under test to the sensing receiving node 103.

[0152] In some embodiments, the sensing transmitting node 102 can be a transmitting antenna.

[0153] In some embodiments, the sensing and transmitting node 102 may be a terminal or a network device.

[0154] In some embodiments, the sensing receiving node 103 can be a receiving antenna.

In this case, the interfaces between or within access network devices involved in this disclosure can be internal interfaces of the open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0159] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0160] In some embodiments, the core network equipment can be a single device including a first network element, which provides SF functionality, etc., or it can be multiple devices or a group of devices, each including a first network element. Network elements can be virtual or physical. The core network includes, for example, at least one of the evolved packet core (EPC), 5G Core Network (5GCN), and next-generation core (NGC).

As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0162] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto.

Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0164] The ISAC system involved in the embodiments of this application is described below.

[0165] The ISAC system comprises sensing devices, sensing TX nodes (STNs), sensing RX nodes (SRNs), and sensing objects (SOs). The ISAC system has six sensing modes:

[0166] (1) Transmitter Receiver Point Monostatic (TRP Monostatic) mode;

[0167] (2) Dual Transmission Receiver Point (TRP-TRP bistatic) mode;

[0168] (3) Terminal-Transmitter-Receiver Point Bistatic (UE-TRP) mode;

[0169] (4) Transmission Receiver Point-Terminal Bistatic (TRP-UE bistatic) mode;

[0170] (5) Terminal monostatic mode;

[0171] (6) Terminal-to-Terminal Dual-Station (UE-UE bistatic) mode.

[0172] In some embodiments, the terms "perceived object", "object under test", "object under test", "perceived target", "target object", "target object" and other similar terms can be used interchangeably.

[0173] Figure 1B is a schematic diagram of an ISAC system sensing mode according to an embodiment of the present disclosure. As shown in Figure 1B, the above six modes are explained.

[0174] Mode 1: Base station A transmits and receives signals (i.e., TRP mono-static). Base station A transmits a sensing reference signal. After the sensing reference signal passes through the object under test O1, the base station receives the reflected / scattered sensing reference signal and performs measurements.

[0175] Mode 2: Base station A transmits and base station B receives (i.e., TRP-TRP bi-static). Base station A transmits a sensing reference signal, which passes through the object under test O2. Base station B then receives the reflected / scattered sensing reference signal and performs measurements.

[0176] Mode 3: Terminal A transmits, Base Station A receives (i.e., UE-TRP bi-static). Terminal A sends a sensing reference signal, which passes through the object under test O3. The base station receives the reflected / scattered sensing reference signal and performs measurements.

[0177] Mode 4: Base station B transmits, terminal B receives (i.e., TRP-UE bi-static). Base station B transmits a sensing reference signal. After the sensing reference signal passes through the object under test O4, terminal B receives the reflected / scattered sensing reference signal and performs measurements.

[0178] Mode 5: Terminal A transmits and receives signals independently (i.e., UE mono-static). Terminal A transmits a sensing reference signal. After the sensing reference signal passes through the object under test O5, Terminal A receives the reflected / scattered sensing reference signal and performs measurements.

[0179] Mode 6: Terminal A transmits, Terminal B receives (i.e., UE-UE bi-static). Terminal A sends a sensing reference signal, which passes through the object under test O6. Terminal B receives the reflected / scattered sensing reference signal and performs measurements.

[0180] In some embodiments, the above six modes can be divided into two categories. The first category is mono-static, that is, the transmitting node and the receiving node of the sensing reference signal are deployed on the same device; the second category is bi-static, that is, the transmitting node and the receiving node of the sensing reference signal are deployed on different devices.

[0181] In the aforementioned sensing network, in order to provide high-performance sensing services, the sensing reference signal should occupy as many resources as possible in the frequency domain, time domain, and spatial domain. However, this will reduce the resource utilization efficiency in the sensing network.

[0182] Therefore, how to improve the efficiency of resource utilization in the sensing network is an urgent problem to be solved.

[0183] This disclosure provides a communication method, communication device, communication system, storage medium, and program product to improve resource utilization efficiency in a sensing network.

[0184] In some embodiments, the communication system includes: a sensing device (i.e., a first node), a first sensing transmitting node, a second sensing transmitting node, a first sensing receiving node, a second sensing receiving node, and a measured object.

[0185] In some embodiments, the first sensing transmitting node is a sensing transmitting node used to detect the object under test. In some embodiments, the number of first sensing transmitting nodes can be one or more.

[0186] In some embodiments, the first sensing receiving node is a sensing receiving node used to detect the object under test. In some embodiments, the number of first sensing receiving nodes can be one or more.

[0187] In some embodiments, the second sensing transmitting node is a sensing transmitting node used for tracking the object under test. In some embodiments, the number of second sensing transmitting nodes can be one or more.

[0188] In some embodiments, the second sensing receiving node is a sensing receiving node used for tracking the object under test. In some embodiments, the number of second sensing receiving nodes can be one or more.

[0189] In some embodiments, in single-site sensing mode, the sensing transmitting node and the sensing receiving node can be the same node.

[0190] In some embodiments, in the dual-station sensing mode, the sensing transmitting node and the sensing receiving node can be different nodes.

[0191] In some embodiments, in a sensing network, the number of sensing nodes (such as first sensing transmitting nodes and first sensing receiving nodes) used to detect the object under test can be greater than or equal to the number of sensing nodes (such as second sensing transmitting nodes and second sensing receiving nodes) used to track the object under test, thereby improving the utilization efficiency of sensing resources in the sensing network. In one example, among multiple first sensing transmitting nodes, some or all of the first sensing transmitting nodes are reused as second sensing transmitting nodes. Correspondingly, among multiple first sensing receiving nodes, some or all of the first sensing receiving nodes are reused as second sensing receiving nodes.

[0192] In some embodiments, the number of objects under test can be one or more. In one example, the number of objects under test is multiple, and the objects under test may include a first object under test and a second object under test.

[0193] In some embodiments, the communication system described above may also include other sensing transmitting nodes and other sensing receiving nodes. More sensing transmitting nodes send more reference signals to more sensing receiving nodes to obtain more measurement quantities, thereby enabling the detection of the object under test based on more measurement quantities, thereby improving the detection efficiency.

[0194] In some embodiments, each sensing receiving node may receive sensing reference signals transmitted by one or more sensing transmitting nodes. In one example, the sensing reference signal may also be referred to as a reference signal (denoted as RS).

[0195] In some embodiments, the sensing device knows the location of each sensing transmitting node and each sensing receiving node.

[0196] In some embodiments, a sensing transmitting node may be associated with one or more sensing receiving nodes. These sensing receiving nodes are capable of processing reference signals transmitted by the associated sensing transmitting node, but not responding to reference signals transmitted by non-associated sensing transmitting nodes.

[0197] In some embodiments, a sensing transmitting node is associated with a sensing receiving node, and the sensing transmitting node and the associated sensing receiving node can form a sensing node pair. In one example, a first sensing transmitting node is associated with a first sensing receiving node, and the first sensing transmitting node and the first sensing receiving node form a sensing node pair; a second sensing transmitting node is associated with a second sensing receiving node, and the second sensing transmitting node and the second sensing receiving node form a sensing node pair.

[0198] In some embodiments, terms such as "detection", "initial detection", "measurement", and "positioning" can be used interchangeably.

[0199] The following explanation uses a system architecture consisting of STN A, SRN A, STN B, and SRN B as an example to illustrate the above communication scheme. STN A and SRN A form sensing node pair A, and STN B and SRN B form sensing node pair B.

[0200] In some embodiments, in single-site sensing mode, STNA and SRNA can be deployed on the same device.

[0201] In some embodiments, in multi-station sensing mode, STN A and SRN A can be deployed on two different devices, and STN B and SRN B can be deployed on two different devices.

[0202] Figure 2A is a first exemplary interaction diagram of a communication method provided according to an embodiment of the present disclosure. As shown in Figure 2A, the present disclosure relates to a communication method. Executed by the aforementioned communication system, the communication method includes steps S2101 to S2109.

[0203] In step S2101, the sensing device sends the fourth information.

[0204] In some embodiments, STN A receives fourth information.

[0205] In some embodiments, the sensing function device may configure resources for detection for each STNA and instruct the STNA via fourth information. In this case, the first sensing transmitting node may include the STNA.

[0206] In some embodiments, the fourth information is used to indicate resources (such as the second resource) configured by the sensing device for detection. In some embodiments, the fourth information is used to indicate resources configured by the sensing device for detection for STN A. In some embodiments, the fourth information is used to indicate resources configured by the sensing device for detection for sensing node pair A. In one example, the resources for detection (such as the second resource) may also be referred to as detection resources.

[0207] In some embodiments, the fourth information can be broadcast information and transmitted within a broadcast message. In some embodiments, the sensing device can configure detection resources for one or more sensing receiving nodes and indicate their respective detection resources to each sensing transmitting node through different information fields in the broadcast information. In this case, the fourth information can be used to indicate the detection resources of one or more sensing transmitting nodes. In one example, the fourth information indicates the detection resources of STN A through a first information field, enabling STN A to determine its own detection resources from the first information field after receiving the fourth information. In another example, the fourth information indicates the detection resources of STN A through a first information field and the detection resources of STN B through a second information field, enabling STN A to determine its own detection resources from the second information field after receiving the fourth information, and STN B to determine its own detection resources from the second information field after receiving the fourth information.

[0208] In one example, the broadcast information mentioned above can be system information, such as a main information block (MIB) or a system information block (SIB). In one embodiment, the SIB can include at least one of SIB1 to SIBx, where x is a positive integer. Of course, the fourth information can also be other system information, and this disclosure does not specifically limit it.

[0209] In some embodiments, the fourth information can be transmitted via downlink higher-layer signaling and carried within a higher-layer message. In some embodiments, the sensing function device can configure probe resources for one or more sensing receiving nodes and indicate their respective probe resources to each sensing transmitting node via higher-layer signaling. In this case, the fourth information can be used to indicate the probe resources of a sensing transmitting node. In one example, the fourth information sent to STN A indicates the probe resources of STN A, enabling STN A to determine its own probe resources upon receiving the fourth information.

[0210] In one example, the aforementioned downlink higher-layer signaling may include signaling from radio resource control (RRC) messages, media access control (MAC) control element (CE), downlink control information (DCI), physical downlink control channel (PDCCH), physical downlink share channel (PDSCH), and non-access stratum (NAS) messages. Of course, the fourth information can also be other downlink higher-layer signaling, and this disclosure does not specifically limit this type of signaling.

[0211] In some embodiments, the detection resources may include at least one of the following: a configuration of one or more reference signals (such as a first reference signal) for detection, and a sensing node associated with the configuration of the reference signals for detection. In one example, the reference signal for detection (such as the first reference signal) may be referred to as a detection reference signal, and the configuration of one or more reference signals for detection (such as the configuration of the first reference signal) may be referred to as the configuration of the detection reference signal. In some embodiments, different detection reference signals may have different spatial characteristics and different processing power requirements; therefore, the sensing nodes associated with different configurations of detection reference signals may be different.

[0212] In some embodiments, the configuration of the probe reference signal may include first indication information and first configuration information, where the first indication information is associated with a first configuration. In some embodiments, the first indication information is used to indicate that the use of the reference signal is for probe. In some embodiments, the first configuration information is used to indicate one or more reference signals. In some embodiments, the first indication information is used to indicate the use of the reference signal indicated by the first configuration information. In one example, the first indication information may be an element "usage" with a value of a first value (e.g., 0), indicating that the use of the reference signal is for probe. In one example, the first indication information may be an element "usage" with a value of a first value (e.g., 0), indicating that the use of the reference signal is for initial probe. In one example, the element "usage" may be associated with configuration 1, configuration 2, and configuration 3 of the reference signal; then, reference signal 1 corresponding to configuration 1, reference signal 2 corresponding to configuration 2, and reference signal 3 corresponding to configuration 3 are used to probe the object under test. In other words, reference signal 1, reference signal 2, and reference signal 3 are probe reference signals.

[0213] In some embodiments, the configuration of the probe reference signals may include only the first configuration information. In this case, the fourth information is carried in a message for configuring probe resources, meaning that the purpose of one or more reference signals indicated by the first configuration information is configured by default as probes. In some embodiments, the configuration of the probe reference signals may also include only the first indication information. In this case, the configuration of the probe reference signals may also be protocol-defined, meaning that one or more reference signals are known, and the purpose of these reference signals is configured through the first indication information.

[0214] In some embodiments, the first configuration information indicates multiple reference signals, which may belong to the same reference signal group (RS group) or different reference signal groups. In other words, the sensing device can configure one or more reference signal groups for STN A, and each reference signal group includes one or more reference signals for the purpose of detection.

[0215] In some embodiments, the first configuration information may include one or more configuration indices. These configuration indices can indicate one or more reference signals.

[0216] In some embodiments, the first configuration information may include one or more configuration parameters. These configuration parameters can indicate one or more reference signals. In some embodiments, the one or more configuration parameters may include at least one of the following: time-domain configuration parameters of the reference signal, frequency-domain configuration parameters of the reference signal, and spatial-domain configuration parameters of the reference signal. In one example, the time-domain configuration parameters may include the duration of the sensing frame, time-domain density, etc. In one example, the frequency-domain configuration parameters may include bandwidth, frequency-domain density, etc. In one example, the spatial-domain configuration parameters may include beam direction, beamwidth, etc.

[0217] In some embodiments, the configurations of multiple reference signals belonging to the same reference signal group may be different. In some embodiments, the configuration of the reference signals may include the configuration of the reference signals in at least one of the time domain, frequency domain, and spatial domain. In some embodiments, the configurations of different reference signals in at least one of the time domain, frequency domain, and spatial domain are different. In some embodiments, the configurations of different reference signals in the time domain, frequency domain, and spatial domain are all different. In the embodiments of this disclosure, because the configurations of multiple detection reference signals are different, more diverse detection reference signals can be provided for the detection of the object under test, thereby providing more accurate detection results and improving detection efficiency.

[0218] In some embodiments, the configuration of the detection reference signal may further include fourth indication information, which indicates the transmission period of the reference signal. In this case, the transmission period is configured by the sensing device. In some embodiments, the transmission period may be configured for a single reference signal, meaning different reference signals can be configured with different transmission periods. In some embodiments, the transmission period may be configured for a group of reference signals, meaning different groups of reference signals can be configured with different transmission periods. Reference signals belonging to the same group have the same transmission period, while reference signals belonging to different groups have different transmission periods.

[0219] In some embodiments, the transmission period may also be specified according to the protocol, in which case the configuration of the probe reference signal may not include the fourth indication information.

[0220] In some embodiments, the detection resource may further include fifth indication information. The fifth indication information is used to indicate a sensing node associated with the configuration of the plurality of reference signals. In some embodiments, the fifth indication information may indicate a sensing node associated with the configuration of the plurality of reference signals, such as STN A, SRN A, or sensing node pair A. In some embodiments, the fifth indication information may indicate a sensing transmitting node associated with the configuration of the plurality of reference signals, such as STN A. In some embodiments, the fifth indication information may indicate a sensing receiving node associated with the configuration of the plurality of reference signals, such as SRN A. In some embodiments, the fifth indication information may indicate a sensing node pair associated with the configuration of the plurality of reference signals, such as sensing node pair A. In some embodiments, the fifth indication information may indicate at least one of a sensing transmitting node, a sensing receiving node, and a sensing node pair associated with the configuration of the plurality of reference signals, such as at least one of STN A, SRN A, and sensing node pair A.

[0221] In one example, the fifth indication information may include at least one of the identifiers of STN A and SRN A. In one example, the fifth indication information may include the identifier of sensing node A. In one example, the fifth indication information may include the identifier of sensing node A and at least one of the identifiers of STN A and SRN A.

[0222] In some embodiments, the SNRA can be associated with one or more of the aforementioned configurations of multiple reference signals. In this case, the SNRA can detect the object under test based on the associated reference signal. In some embodiments, the configuration of the same reference signal can be associated with one or more sensing receiving nodes, and the configurations of reference signals configured for different sensing receiving nodes can include the same configuration.

[0223] In some embodiments, different reference signals have the same spatial characteristics, the same processing power requirements, etc. In this case, the sensing node associated with the configuration of the reference signal can be a default setting, and the configuration of the detection reference signal may not include the fifth indication information.

[0224] In some embodiments, the fourth information may include at least one of the first instruction information, the first configuration information, the fourth instruction information, and the fifth instruction information.

[0225] In some embodiments, the terms "reference signal", "detection reference signal", "reference signal for detection", and "reference signal for detection purposes" can be used interchangeably.

[0226] In one example, Figure 3A is a schematic diagram of a detection resource provided according to an embodiment of the present disclosure. As shown in Figure 3A, the detection resource configured by the sensing device for STN A may include three configurations of reference signals, such as configuration 1, configuration 2, and configuration 3. Wherein, the reference signal corresponding to configuration 1 is reference signal 1, the reference signal corresponding to configuration 2 is reference signal 2, and the reference signal corresponding to configuration 3 is reference signal 3. Reference signals 1, 2, and 3 have different configurations in both the time and frequency domains. Reference signals 1, 2, and 3 belong to the same reference signal group, and the transmission period of this reference signal group is T. Reference signals 1, 2, and 3 are periodically transmitted in the time domain according to T.

[0227] In step S2102, STN A sends a probe reference signal.

[0228] In some embodiments, the SNNA receives a probe reference signal transmitted by the STNA. In some embodiments, the probe reference signal transmitted by the STNA is reflected or scattered to the SNNA by the object under test.

[0229] In some embodiments, if SRN A is a base station (BS), the configuration of the probe reference signals that the BS, acting as the SRN, needs to listen to can be directly configured via SF. In some embodiments, if SRN A is a UE, for a UE in RRC idle state, the configuration of the probe reference signals that the UE, acting as the SRN, needs to listen to can be configured via paging signaling. In some embodiments, if SRN A is a UE, for a UE in RRC connected state, the configuration of the probe reference signals that the UE, acting as the SRN, needs to listen to can be configured via higher-layer signaling. In one example, the higher-layer signaling can be the aforementioned downlink higher-layer signaling.

[0230] In some embodiments, after receiving the fourth information, the STNA can determine the detection resources configured for itself by the sensing function device, and then the STNA uses its own detection resources to send a detection reference signal.

[0231] In some embodiments, an STNA can transmit one or more probe reference signals. In some embodiments, an STNA can be associated with multiple SRNAs, each of which receives one or more probe reference signals.

[0232] In some embodiments, the probe reference signal transmitted by STNA may be part or all of the reference signals in the probe resource.

[0233] In some embodiments, the detection reference signal transmitted by the STNA reaches the SRN A via at least one of a line-of-sight path and a non-line-of-sight path between the STNA and the SRN A. In some embodiments, if a non-line-of-sight path exists between the STNA and the SRN A, it indicates that a target object exists between the STNA and the SRN A.

[0234] In some embodiments, the object under test on the non-line-of-sight path between STN A and SRN A and the object under test on the non-line-of-sight path between STN B and SRN B can be the same object or different objects.

[0235] In step S2103, SRN A obtains second detection data based on the detection reference signal.

[0236] In one embodiment, the SRN A calculates for each detection reference signal it receives to obtain corresponding second detection data.

[0237] In one example, the second detection data may include angle of arrival (AOA), time of arrival (TOA), time difference of arrival (TDOA), round trip time (RTT), received signal strength (RSS), reference signal receiving quality (RSRQ), and reference signal receiving power (RSRP), etc. Of course, the second detection data may also include other measurements, and this disclosure does not specifically limit this.

[0238] In some embodiments, when the SRN A receives multiple probe reference signals, the SRN A can acquire measurements of the multiple probe reference signals (such as second probe data). In some embodiments, when the SRN A receives only one probe reference signal, the SRN A can acquire measurements of that probe reference signal (such as second probe data).

[0239] In step S2104, SRN A determines the first detection data based on the second detection data.

[0240] In some embodiments, the SNRA determines valid detection data (such as first detection data) from the second detection data, which can be used by the sensing device to determine whether a measured object has been detected. In some embodiments, the first detection data determined by the SNRA can be used by the sensing device to determine whether the SNRA has detected a measured object.

[0241] In some embodiments, the first detection data is second detection data sent by the sensing receiving node to the sensing function device. In some embodiments, the sensing receiving node can obtain multiple second detection data by measuring a detection reference signal, and the first detection data is one or more of the multiple second detection data.

[0242] In some embodiments, when the SRN A receives a probe reference signal, the SRN A can obtain a second probe data. The SRN A can then determine the obtained second probe data as the first probe data.

[0243] In some embodiments, when the SRN A receives multiple reference signals, the SRN A can acquire multiple second detection data. Then, the SRN A can determine one or more of the acquired second detection data as the first detection data.

[0244] In some embodiments, the SRNA may determine the first probe data based on at least one of the following: the signal quality of the probe reference signal, the number of probe reference signals from the same sensing transmitting node, and the number of probe data reported.

[0245] In some embodiments, the SRNA can determine the first detection data from multiple second detection data based on the signal quality of multiple detection reference signals. The better the signal quality of the detection reference signal, the greater the likelihood that its associated second detection data will be identified as the first detection data.

[0246] In some embodiments, when the SRN A receives multiple probe reference signals, these signals may originate from different sensing transmitting nodes. The SRN A can then select the number of probe reference signals to transmit to determine the first probe data from the multiple second probe data. In one example, the SRN A can select the second probe data of the SRN A whose number of transmitted probe reference signals reaches a preset threshold as the first probe data. In some embodiments, the preset threshold may be configured by the sensing device, specified by a protocol, or determined by the sensing receiving node based on its own implementation.

[0247] In some embodiments, the SRNA can select a second probe data that meets the reporting quantity from a plurality of second probe data as the first probe data based on the number of probe data to be reported configured in the probe reporting configuration.

[0248] In some embodiments, the selection of the first probe data can also be random and arbitrary. That is, the SRNA can randomly select one or more of the obtained second probe data as the first probe data.

[0249] In some embodiments, step S2104 can be omitted, and SRN A directly reports all the acquired second detection data as the first detection data to the sensing function device.

[0250] In step S2105, SRN A sends the first information.

[0251] In some embodiments, the SRN A sends first information.

[0252] In some embodiments, the sensing device receives first information sent by the RN A.

[0253] In some embodiments, after determining the first detection data based on the second detection data, the SRNA determines the first information based on the first detection data.

[0254] In some embodiments, the first information includes sensing information of the sensing receiving node. In some embodiments, the first information includes sensing information of the RN A.

[0255] In some embodiments, the first information may include at least one of first event information, first probe data, and the detection result of the object under test. In some embodiments, the first information determined by the SNRA may include at least one of first event information, first probe data, and the detection result of the object under test detected by the SNRA. In one example, the first information may include first event information and the detection result of the object under test. In one example, the first information may include first probe data.

[0256] In some embodiments, the first event information is used to indicate that a target object has been detected. In some embodiments, the first information sent by the SNRA may include the first event information of the SNRA to indicate to the sensing device that the SNRA has detected a target object.

[0257] In some embodiments, after determining the first detection data, the SNRA can process the first detection data to determine whether it has detected the object being tested. If the SNRA determines that it has detected the object being tested, the first information may include the SNRA's first event information.

[0258] In some embodiments, the object detected by SRNA and the object detected by SRNA may include the same object or different objects.

[0259] In some embodiments, the detection result of the object under test is determined based on first detection data. In some embodiments, the SNRA processes the first detection data to determine that it has detected the object under test and to obtain the detection result of the detected object. In one example, the detection result of the object under test may include the position, size, velocity, acceleration, etc. of the object under test. In one example, the SNRA locates the object under test according to at least one of AOA, TOA, TDOA, RTT, RSS, RSRQ, and RSRP, thereby determining the position, size, velocity, etc. of the object under test.

[0260] In some embodiments, the first information may be uplink higher-layer signaling and transmitted within a higher-layer message. In one example, the aforementioned uplink higher-layer signaling may include signaling in RRC messages, uplink control information (UCI), PUCCH, PDSCH, NAS messages, etc. Of course, the first information may also be other uplink higher-layer signaling, and this disclosure does not specifically limit this type of information.

[0261] In some embodiments, if the SNRA detects the object under test, step S2105 is performed. In some embodiments, if the SNRA does not detect the object under test, steps S2105 to S2109 are omitted.

[0262] In some embodiments, when the SNRA sends first detection data to the sensing device, step S2105 is executed regardless of whether the SNRA detects the object being tested. At this time, the first information includes the first detection data.

[0263] This completes the detection process of STRNA and SNRNA on the tested object.

[0264] In step S2106, SRN A sends the third information.

[0265] In some embodiments, the SRN A sends third information.

[0266] In some embodiments, the sensing device receives third information sent by the SRN A.

[0267] In some embodiments, the third information is used to indicate the sensing and receiving node's ability to simultaneously track multiple objects under test. In some embodiments, the third information is used to indicate the sensing and receiving node's support capability for simultaneously tracking multiple objects under test. In some embodiments, the third information is used to indicate whether the sensing and receiving node supports simultaneously tracking multiple objects under test. In some embodiments, the third information is used to indicate whether the sensing and receiving node supports tracking multiple objects under test at the same time. In some embodiments, "simultaneously" and "at the same time" can be understood as the same period of time, and "simultaneously tracking multiple objects under test" and "tracking multiple objects under test at the same time" can be understood as tracking multiple objects under test within the same time period.

[0268] In some embodiments, the third information sent by the SNRA is used to indicate whether the SNRA supports tracking multiple objects under test simultaneously.

[0269] In some embodiments, the third information is used to indicate that the sensing receiving node supports simultaneous tracking of multiple objects under test. Alternatively, in some embodiments, the third information is used to indicate that the sensing receiving node does not support simultaneous tracking of multiple objects under test. In some embodiments, the third information sent by the SRN A is used to indicate that the SRN A supports simultaneous tracking of multiple objects under test. Alternatively, in some embodiments, the third information sent by the SRN A is used to indicate that the SRN A does not support simultaneous tracking of multiple objects under test.

[0270] In some embodiments, the sensing device can configure resources (such as a first resource) for tracking for the sensing transmitting node and the sensing receiving node based on third information.

[0271] In some embodiments, the sensing device configures resources for tracking for STN A based on third information sent by SRN A. In some embodiments, the sensing device configures resources for tracking for sensing node A based on third information sent by SRN A.

[0272] In some embodiments, step S2106 can be omitted. In this case, the sensing function device can determine whether the SN RA supports tracking multiple objects under test at the same time based on the default settings, and then configure resources for tracking the objects under test for the SN RA and SN RA accordingly.

[0273] In step S2107, the sensing device sends the second information.

[0274] In some embodiments, STN A receives second information.

[0275] In some embodiments, the sensing device sends second information based on first information sent by the SNRA. In some embodiments, the sensing device sends second information based on both the first and third information sent by the SNRA.

[0276] In some embodiments, the second information is used to indicate resources (such as the first resource) for tracking the object under test. In some embodiments, the second information is used to indicate resources configured by the sensing function device for tracking STN A. In some embodiments, the second information is used to indicate resources configured by the sensing function device for tracking the object under test for sensing node pair A. In one example, the resources for tracking the object under test may also be referred to as tracking resources. In some embodiments, tracking resources may be updated as the object under test moves.

[0277] In some embodiments, when the SRN A detects one or more objects under test, the sensing device can configure tracking resources for each object under test and send second information to the sensing node used to track the object under test to indicate the tracking resources of the object under test. In some embodiments, if the SRN A detects object O1 (such as the first object under test), the sensing device can configure tracking resources for object O1 and send second information to the SRN A to indicate the tracking resources of object O1. In some embodiments, if both the SRN A and SRN B detect object O1, the sensing device can configure tracking resources for object O1 for both the SRN A and SRN B, and send second information to both the SRN A and SRN B to indicate the tracking resources of object O1. At this time, the second information sent to STN A can indicate the part of the tracking resources of the object under test O1 associated with STN A and / or SRN A, and the second information sent to STN B can indicate the part of the tracking resources of the object under test O1 associated with STN B and / or SRN B.

[0278] In some embodiments, the second information can be broadcast information and transmitted within a broadcast message. In some embodiments, the sensing function device can configure tracking resources for one or more sensing receiving nodes and indicate their respective tracking resources to each sensing transmitting node through different information fields in the broadcast information. In this case, the second information can be used to indicate the tracking resources of one or more sensing transmitting nodes. In one example, the second information indicates the tracking resources of STN A through a first information field, so that STN A can determine its own tracking resources from the first information field after receiving the second information. In one example, the second information indicates the tracking resources of STN A through a first information field and the tracking resources of STN B through a second information field, so that STN A can determine its own tracking resources from the second information field after receiving the second information, and STN B can determine its own tracking resources from the second information field after receiving the second information. In one example, the broadcast information can be system information, such as MIB, SIB, etc. In one embodiment, SIB can include at least one of SIB1 to SIBx. Of course, the second information can also be other system information, and this disclosure does not specifically limit this.

[0279] In some embodiments, the second information can be transmitted via downlink higher-layer signaling and carried within a higher-layer message. In some embodiments, the sensing function device can configure tracking resources for one or more sensing receiving nodes and indicate their respective tracking resources to each sensing transmitting node via higher-layer signaling. In this case, the second information can be used to indicate the tracking resources of a sensing transmitting node. In one example, the second information sent to STN A indicates the tracking resources of STN A, enabling STN A to determine its own tracking resources upon receiving the second information.

[0280] In one example, the aforementioned downlink higher-layer signaling may include signaling in RRC messages, MAC CE, DCI, PDCCH, PDSCH, NAS messages, etc. Of course, the second information can also be other downlink higher-layer signaling, and this disclosure does not specifically limit this.

[0281] In some embodiments, a tracking resource for a target object may include at least one of the following: a sensing node for tracking the target object, a configuration of one or more reference signals (such as a second reference signal) for tracking, and a tracking priority for the target object. In one example, the reference signal for tracking may be referred to as a tracking reference signal, and the configuration of one or more reference signals for tracking (such as the configuration of a second reference signal) may be referred to as the configuration of the tracking reference signal.

[0282] In some embodiments, the sensing nodes used to track the object under test may include at least one of the following: one or more sensing transmitting nodes used to track the object under test, one or more sensing receiving nodes used to track the object under test, and one or more pairs of sensing nodes used to track the object under test.

[0283] In some embodiments, the sensing node used to track the object under test can be indicated by the node's identifier. In this case, the second information includes sixth indication information, indicating the sensing node used to track the object under test. In some embodiments, the second information sent to STN A may include the sixth indication information, indicating the sensing node used to track the object under test, such as STN A and SRN A. In one example, the sixth indication information may include at least one of the identifiers of STN A and SRN A. In one example, the sixth indication information may include the identifier of sensing node A. In one example, the fifth indication information may include the identifier of sensing node A and at least one of the identifiers of STN A and SRN A.

[0284] In some embodiments, when a tested object is detected by a sensing receiving node, the sensing node used to track the tested object may include the sensing receiving node that detected the tested object, its associated sensing transmitting node, and the sensing node pair to which it belongs. In some embodiments, when a tested object is detected by multiple sensing receiving nodes, the sensing nodes used to track the tested object may include multiple sensing receiving nodes that detected the tested object, the sensing transmitting node associated with each sensing receiving node, and the sensing node pair to which each sensing receiving node belongs. In one example, the first information sent by SRN A indicates that SRN A has detected the tested object O1. Then, the sensing nodes used to track the tested object O1 include at least one of SRN A, STN A, and sensing node pair A. In this case, the sixth indication information may include at least one of the identifier of SRN A, the identifier of STN A, and the identifier of sensing node pair A.

[0285] In some embodiments, when a measured object is detected by multiple sensing receiving nodes, the sensing device can select one or more sensing receiving nodes that meet preset conditions from the multiple sensing receiving nodes to track the measured object. In this case, the sensing node used to track the measured object is a subset of the sensing nodes used to detect the measured object. In other words, a subset of the sensing nodes that detected the measured object is reused to track the measured object.

[0286] In one example, the preset conditions could be being closest to the object under test, being within a preset range around the object under test, having a reference signal reception quality exceeding a preset threshold, or having a reference signal reception power exceeding a preset threshold. In some embodiments, the preset conditions can be determined by the sensing device itself, configured by the network, or specified by a protocol. In one example, SRN A and SRN B detect the object under test O1. The sensing device can select SRN A, which is closest to the object under test O1, from SRN A and SRN B to track the object under test O1. At this time, SRN A, SRN A, and sensing node pair A are used to both detect and track the object under test O1, while SRN B, SRN B, and sensing node pair B are used only to detect the object under test O1.

[0287] In some embodiments, the SNRA can be associated with one or more of the above-described configurations of multiple reference signals, in which case the SNRA is able to track the object under test based on the associated reference signal.

[0288] In some embodiments, the configuration of the same reference signal may be associated with one or more sensing receiving nodes, and the configuration of the reference signal configured for different sensing receiving nodes may include the same configuration.

[0289] In some embodiments, different reference signals may have the same spatial characteristics and the same processing power requirements. In this case, the sensing node associated with the configuration of the tracking reference signal may be a default setting, and the second information may not include the sixth indication information. In one embodiment, the sensing node associated with the configuration of the tracking reference signal may be the sensing node associated with the detection reference signal. In other words, the sensing node used to detect the object under test continues to be used for tracking the object under test, and in this case, the second information may not include the sixth indication information.

[0290] In some embodiments, the configuration of the tracking reference signal may include at least one of second configuration information, second indication information, and third indication information. In this case, the second indication information is associated with the second configuration information. In some embodiments, the second information may further include at least one of the second configuration information, the second indication information, and the third indication information.

[0291] In some embodiments, the second indication information is used to indicate that the usage of the reference signal is tracking. In some embodiments, the second configuration information is used to indicate one or more reference signals. In some embodiments, the second indication information is used to indicate the usage of the reference signal indicated by the second configuration information. In one example, the second indication information can be an element "usage" with a value of a second value (such as 1), indicating that the reference signal is used for tracking. In one example, the element "usage" can be associated with configuration 3 of the reference signal; then, the reference signal 3 corresponding to configuration 3 is used to track the object under test. In other words, reference signal 3 is a tracking reference signal.

[0292] In some embodiments, the configuration of the tracking reference signal may include only the second configuration information. In this case, the second information is carried in a message for configuring tracking resources; that is, the purpose of one or more reference signals indicated by the second configuration information is configured by default as tracking. In some embodiments, the configuration of the tracking reference signal may also include only the second indication information. In this case, the configuration of the tracking reference signal may be protocol-defined; that is, one or more reference signals are known, and the purpose of these reference signals is configured as tracking through the second indication information. In some embodiments, the tracking reference signal may reuse all of the probe reference signals. In this case, the purpose of one or more reference signals indicated by the first configuration information can be changed to "tracking" by sending only the second indication information, or "tracking" can be added to the purpose of one or more reference signals indicated by the first configuration information.

[0293] In some embodiments, the second configuration information indicates multiple reference signals, which may belong to the same reference signal group (RS group) or different reference signal groups. In other words, the sensing device can configure one or more reference signal groups for STN A, and each reference signal group includes one or more reference signals for tracking purposes.

[0294] In some embodiments, the second configuration information may include one or more configuration indices. These configuration indices can indicate one or more reference signals.

[0295] In some embodiments, the second configuration information may include one or more configuration parameters. These configuration parameters can indicate one or more reference signals. In some embodiments, the one or more configuration parameters may include at least one of the following: time-domain configuration parameters of the reference signal, frequency-domain configuration parameters of the reference signal, and spatial-domain configuration parameters of the reference signal. In one example, the time-domain configuration parameters may include the duration of the sensing frame, the time-domain density, etc. In one example, the frequency-domain configuration parameters may include bandwidth, frequency-domain density, etc. In one example, the spatial-domain configuration parameters may include beam direction, beamwidth, etc.

[0296] In some embodiments, the configurations of multiple reference signals belonging to the same reference signal group may be different. In some embodiments, the configuration of the reference signals may include the configuration of the reference signals in at least one of the time domain, frequency domain, and spatial domain. In some embodiments, the configurations of different reference signals in at least one of the time domain, frequency domain, and spatial domain are different. In some embodiments, the configurations of different reference signals in the time domain, frequency domain, and spatial domain are all different. In the embodiments of this disclosure, because the configurations of multiple tracking reference signals are different, more diverse tracking reference signals can be provided for the tracking of the object under test, thereby providing more accurate tracking results and improving tracking efficiency.

[0297] In some embodiments, the tracking reference signal used by the same sensing transmitting node to track a measured object can be one or more of the sensing transmitting node's probe reference signals. In other words, the tracking reference signal can reuse some or all of the probe reference signals.

[0298] In some embodiments, the configuration of the tracking reference signal may further include third indication information, which indicates the activation duration of the object under test. In some embodiments, the tracking reference signal is activated within an associated activation duration to track the object under test. In some embodiments, the tracking reference signal is deactivated after the associated activation duration expires. In some embodiments, the activation duration is configured by the sensing device. In some embodiments, the activation duration may be configured for a reference signal, that is, different reference signals may be configured with different activation durations. In some embodiments, the activation duration may be configured for a group of reference signals, that is, different groups of reference signals may be configured with different activation durations, so that reference signals belonging to the same group of reference signals are configured with the same activation duration, and reference signals belonging to different groups of reference signals are configured with different activation durations.

[0299] In some embodiments, the activation duration may also be specified according to the protocol, in which case the configuration of the tracking reference signal may not include third indication information.

[0300] In some embodiments, the activation or deactivation of the tracking reference signal can also be indicated by a downlink command. In one example, the SF sends a fifth message to the STN A, the fifth message indicating that one or more tracking reference signals are activated, or the fifth message indicating that one or more tracking reference signals are deactivated. In one example, the fifth message can be the aforementioned downlink higher-layer signaling.

[0301] In some embodiments, the same sensing receiving node can detect multiple objects under test. In this case, the sensing device can also configure a tracking priority for each object under test, allowing the sensing node to track multiple objects under test associated with it first according to the tracking priority. Here, the objects under test associated with the sensing node can be understood as the objects under test detected by the sensing receiving node, or as the objects under test detected by the sensing receiving node associated with the sensing sending node, or as the objects under test detected by the sensing receiving node in the context of the sensing node.

[0302] In some embodiments, the tracking resource further includes the tracking priority of one or more objects under test. In some embodiments, the second information may include seventh indication information, which is used to indicate the tracking priority of one or more objects under test associated with the sensing transmitting node. In one example, the SRN A detects objects under test O1 (such as the first object under test) and objects under test O2 (such as the second object under test), and the seventh indication information may include the priority of objects under test O1 and the priority of objects under test O2. In one example, if the tracking priority of objects under test O1 is higher than the tracking priority of objects under test O2, then the STN A and SRN A prioritize tracking objects under test O1. In one example, the STN A prioritizes transmitting the tracking reference signal associated with objects under test O1. In one example, the SRN A prioritizes processing the tracking reference signal associated with objects under test O1 to obtain the tracking result of objects under test O1.

[0303] In some embodiments, the second information may include at least one of the sixth instruction information, the first configuration information, the second instruction information, the third instruction information, and the seventh instruction information.

[0304] In some embodiments, the terms "reference signal", "tracking reference signal", "reference signal for tracking", and "reference signal for tracking purposes" can be used interchangeably.

[0305] In step S2108, STN A sends a tracking reference signal.

[0306] In some embodiments, the SRN A receives a tracking reference signal.

[0307] In some embodiments, the SNNA receives a probe reference signal transmitted by the STNA. In some embodiments, the probe reference signal transmitted by the STNA is reflected or scattered to the SNNA by the object under test.

[0308] In some embodiments, after receiving the second information, the STNA can determine the tracking resources configured for itself by the sensing function device, and then the STNA uses its own tracking resources to send a tracking reference signal.

[0309] In some embodiments, an STNA can transmit one or more tracking reference signals. In some embodiments, an STNA can be associated with multiple SRNAs, each of which receives one or more tracking reference signals.

[0310] In some embodiments, the tracking reference signal transmitted by STNA can be some or all of the reference signals in the tracking resource.

[0311] In some embodiments, the tracking reference signal transmitted by the STNA reaches the SRNA via at least one of a line-of-sight path and a non-line-of-sight path between the STNA and the SRNA. In some embodiments, the non-line-of-sight path between the STNA and the SRNA changes as the object being measured moves.

[0312] In one example, Figure 3B is a schematic diagram of a tracking resource provided according to an embodiment of the present disclosure. As shown in Figure 3B, at time t1, the STN A detects the object under test O1. The tracking resource configured for the object under test O1 by the sensing device for the STN A can be configuration 3 of the reference signal. Then, after time t1, the STN A can send the reference signal 3 to track the object under test O1.

[0313] In some embodiments, the STNA may need to transmit other probe reference signals simultaneously with the tracking reference signal. That is, the transmission of probe reference signals and the transmission of tracking reference signals overlap in time. In this case, since the tracking priority of the measured object is higher than the detection priority of the measured object, the STNA prioritizes the transmission of the tracking reference signal.

[0314] In step S2109, SNRA tracks the object under test.

[0315] In some embodiments, the SNRA tracks the object under test based on one or more received tracking reference signals.

[0316] In some embodiments, SRN A calculates for each tracking reference signal it receives to obtain tracking data of the object under test. In some embodiments, SRN B processes the tracking data of the object under test to obtain the tracking result of the object under test, such as position, attitude, velocity, etc. In some embodiments, SRN B can also send the tracking data of the object under test to a sensing function node, which processes the tracking data to obtain the tracking result of the object under test.

[0317] In some embodiments, the tracking results of the object under test change as the object under test moves.

[0318] In one example, tracking data may include AOA, TOA, TDOA, RTT, RSS, RSRQ, RSRP, etc. Of course, tracking data may also include other measurements, which are not specifically limited in this disclosure.

[0319] In some embodiments, when the SRN A receives multiple tracking reference signals, the SRN A can acquire the measurements of the multiple tracking reference signals. In some embodiments, when the SRN A receives only one tracking reference signal, the SRN A can acquire the measurement of that tracking reference signal.

[0320] Thus, the tracking process of the detected object by STNA and SNNA has been completed.

[0321] In some embodiments, other sensing nodes in the sensing system, such as STN B and SRN B, can also perform steps S2101 to S2108 as described above to detect and track the object under test. For the sake of brevity, these steps will not be elaborated upon here.

[0322] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments.

[0328] In some embodiments, terms such as "certain," "preset," "default," "set," "indicated," "a certain," "any," and "first" can be used interchangeably.

[0495] In the following, the technical solutions of the embodiments of this disclosure will be described by way of specific implementation.

[0496] In some embodiments, the SF (e.g., the first node) configures the STN (e.g., STN A) with a sensing reference signal group for initial detection. Each sensing reference signal group contains N sensing reference signal configurations, where N is a positive integer. Different sensing reference signal configurations can have different configurations (and therefore different sensing performance). When a SO (e.g., the object under test) is detected, the SRN (e.g., SRN A) can inform the SF of the initial sensing measurements (e.g., the first detection data) and / or sensing results (e.g., the detection result of the object under test). Then, the SF configures the corresponding sensing resources (e.g., the first resources) for tracking the SO. These sensing resources may include the STN-SRN pair(s) (one or more sensing node pairs) corresponding to the SO, the time-frequency-space resources of the sensing reference signals (sensing RS), etc.

[0497] In some embodiments, the sensing RS used for initial detection is continuously transmitted, somewhat similar to a synchronization block (SSB), sent periodically. Upon detection of an SO, the SF instructs a STN to send a sensing RS for tracking. The tracking sensing RS is sent after the SO is detected and is updated as the SO moves.

[0498] In some embodiments, the SF configures a sensing RS group for the STN, which contains N sensing RS configurations. N≥1.

[0499] In some embodiments, each sensing RS configuration may have different configuration parameters, including: bandwidth, frequency domain density, sensing frame duration, temporal domain density, spatial parameters, etc. Spatial parameters include beam direction, beamwidth, etc.

[0500] In some embodiments, the sensing RS group is transmitted at a period T.

[0501] In some embodiments, due to the different spatial characteristics and required computational processing capabilities of the N sensing RS configurations, the SF can also configure the SRN corresponding to the N sensing RS configurations. If the SRN is a BS, the sensing RS configuration that the BS acting as the SRN needs to listen to can be directly configured through the SF. If the SRN is a UE, for RRC idle UEs, the sensing RS configuration that the UE acting as the SRN needs to listen to can be configured through paging signaling; for RRC connected UEs, the sensing RS configuration that the UE acting as the SRN needs to listen to can be configured through higher-layer signaling.

[0502] In some embodiments, the sensing RS group, serving as a reference signal for initial detection, can be configured for use as "initial detection". In some embodiments, the sensing RS in the sensing RS group can also be reused for SO tracking (Object Tracking), for example, its configuration parameters include the purpose "tracking".

[0503] In some embodiments, after receiving and measuring one or more sensing RS configurations in the sensing RS group, the SRN (such as SRN A) determines whether an SO has been detected and the initial detection result of the SO (position, size, velocity, etc.) based on the measured quantity (such as first detection data). If an SO is detected, SRN A reports the event of SO detection (such as first event information) and the initial detection result (such as the detection result of the object under test) to the SF. Alternatively, SRN A reports the measurement result (such as first detection data) to the SF, which determines whether an SO has been detected and the initial detection result of the detected SO. If an SO is detected, the SF can configure appropriate sensing resources (such as first resources) for the SO based on the initial detection result of the SO.

[0504] In some embodiments, configuring appropriate sensing resources for an SO includes: STN-SRN pair, sensing RS configuration, and SO tracking priority.

[0505] In some embodiments, an STN-SRN pair can be configured with one or more pairs. For example, the SF can configure an STN / SRN pair closer to the SO based on the SO's initial detection position to improve the reception quality of the sensing RS. Alternatively, this pair can be left unconfigured, and the initial detection STN-SRN can continue to be used.

[0506] In some embodiments, a sensing RS configuration is used. This sensing RS configuration can be one or more sensing RS configurations sent by each STN. Based on the initial probe results, the SF can allocate an appropriate sensing RS configuration (such as bandwidth, frequency domain density, sensing frame duration, temporal domain density, spatial parameters, etc.) to the SO.

[0507] In some embodiments, the sensing RS can be configured for use as "tracking". The reason for marking it as tracking is that for the same STN, there may be situations where tracking sensing RS (such as tracking reference signal) and initial detection sensing RS (such as detection reference signal) overlap. In such cases, the transmission of tracking sensing RS can be prioritized (i.e., SO tracking has higher priority).

[0508] In some embodiments, the sensing RS configuration may include an activation duration, such as activating after a timeout, or the sensing RS may be activated by signaling.

[0509] In some embodiments, there may be multiple SOs. In this case, the SF needs to perform the above configuration for each different SO.

[0510] In some embodiments, tracking of different SOs can be prioritized. For example, when the STN needs to send tracking RSs for multiple SOs, the higher priority tracking RSs are sent first; when the SRN needs to process tracking RSs for multiple SOs, the higher priority tracking RSs are processed first.

[0511] In some embodiments, the ability to track multiple SOs simultaneously can be considered a capability of the SRN. The SRX can report to the SF whether it supports tracking multiple SOs, so that the SF can configure the SRN appropriately.

[0512] In some embodiments, the initial detection sensing RS is transmitted and received by a wide-area STN-SRN, but after a SO is detected, the SF will configure the wide-area or micro-area STN-SRN corresponding to the SO to transmit and receive the tracking sensing RS according to the SO's coarsely estimated location, velocity, etc.

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