[0106] The base station transmits and receives signals (or gNB transmits and receives signals, i.e., TRP monostatic). The base station sends sensing signals, which, after passing through the environment or objects in the environment, are received and measured by the base station as reflected / scattered waves.

[0107] Base station A transmits and base station B receives (or gNB A transmits and base station B receives, i.e., TRP-TRP bistatic). Base station A transmits a sensing signal, which passes through the environment or objects in the environment, and base station B receives and measures the reflected / scattered waves.

[0108] The terminal transmits and the base station receives (or the UE transmits and the gNB receives, i.e., UE-TRP bistatic). The terminal sends a sensing signal, which passes through the environment or objects in the environment, and the base station receives and measures the reflected / scattered waves.

[0109] The base station transmits and the terminal receives (or the gNB transmits and the UE receives, i.e., TRP-UE bistatic). The base station sends a sensing signal, which is reflected by the object being measured, and the terminal receives and measures the reflected / scattered wave.

[0110] Terminal-based self-transmission and self-reception (or UE-based self-transmission and self-reception, i.e., UE monostatic). The terminal sends a sensing signal, which passes through the environment or objects in the environment, and the terminal receives and measures the reflected / scattered waves.

[0111] Terminal A transmits and B receives (or UE A transmits and B receives, i.e., UE-UE bistatic). Terminal A sends a sensing signal, which passes through the environment or objects in the environment, and Terminal B receives and measures the reflected / scattered waves.

[0112] Theoretically, measurements obtained by a base station based on multiple sensing signals are more reliable than those obtained from a single sensing signal; that is, joint sensing is more effective than single-signal sensing. For example, when a base station wants to determine the number of trees in a cell, assuming terminals are randomly distributed within the cell, the base station's sensing signal sent by terminal A is not ideal for detecting trees from its location, and it also struggles to provide comprehensive cell coverage. Measuring using sensing signals from multiple terminals would be more accurate and compensate for the limitations of a single terminal's location. Similarly, the base station could target a single terminal but receive multiple sensing signals from that terminal. If the terminal moves within the cell, it would also obtain sensing signals from multiple different locations, achieving the same effect of joint sensing.

[0113] Taking the UE-TRP scenario as an example, consider a base station coordinating with multiple terminals for sensing. As illustrated above, there are two ways for a base station to obtain multiple sensing signals: 1) The base station continuously obtains sensing signals from a single UE, i.e., the UE is repeatedly scheduled multiple times; 2) The base station obtains sensing signals from at least two UEs, for example, simultaneous multi-frequency reception. The number of UEs covered by a cell is generally not unique. In this case, if the base station wants to obtain more accurate measurement results, triggering measurements on multiple UEs on different resources is an option. Furthermore, by further sharing the measurement results, UEs within the base station's coverage area will obtain comprehensive sensing data. This scheduling can be achieved by scheduling UEs one by one using UE-specific signaling, but this leads to excessive signaling overhead. Scheduling through UE groups can reduce overhead. The practical problem to be solved is how to schedule UEs per-group. This includes both per-group scheduling of UEs to send sensing signals and per-group scheduling of UEs to receive sensing signals.

[0114] To address the aforementioned problems, this disclosure proposes a sensing scheduling method that enables group-based scheduling of terminals receiving sensing signals or group-based scheduling of terminals sending sensing signals. The specific details of this method are as follows.

[0115] Figure 2 is an interactive schematic diagram of the sensing scheduling method according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to a sensing scheduling method for a communication system 100, which may include a network device 101 and a terminal 102. The method includes:

[0116] Step 2101: The network device sends the first information to the terminal.

[0117] In some embodiments, the network device may send first information to N terminals.

[0118] In some embodiments, the network device can send a first signaling message to N terminals, and the first information is included in the first signaling message. In other words, the network device can carry the first information in the first signaling message and send the first signaling message to the terminals, and the terminals can obtain the first information from the received first signaling message.

[0119] In some embodiments, the first signaling includes at least one of the following: core network signaling; Radio Resource Control (RRC) signaling; Media Access Control (MAC) Control Element (CE) signaling; and Downlink Control Information (DCI) signaling.

[0120] In some embodiments, the network device may send a first signaling message to at least one sensing group, the first signaling message including first information, which can enable the scheduling of terminals.

[0121] In some embodiments, the network device may send first information to N terminals. The first information is used to schedule M terminals out of the N terminals to send or receive sensing signals, wherein the M terminals belong to at least one sensing group, each sensing group includes at least one terminal, N and M are positive integers, and M is not higher than N. In other words, the N terminals can be divided into multiple sensing groups, each sensing group has at least one terminal, and the first information can schedule some terminals within some sensing groups.

[0122] In some embodiments, the first information includes at least one of the following: a sensing group identifier, used to identify the sensing group to which the terminal belongs; a sensing group sequence number, used to identify the order in which the terminal is scheduled in the sensing group; a sensing count value, used to identify the number of times the terminal is scheduled; an initial sensing count value, used to identify the initial count value of the terminal being scheduled; a terminal identifier, used to identify the scheduled terminal; and a repetition count, used to identify the number of times the scheduled terminal repeatedly sends or receives sensing signals.

[0123] In some embodiments, the first information can be used to schedule the terminal, which can schedule the terminal to send sensing signals or receive sensing signals.

[0124] In some embodiments, N terminals belong to P sensing groups, M = a * P, where a ≥ 1 and is a positive integer; or, N terminals belong to P sensing groups, where the first sensing group in the P sensing groups includes Q terminals, M = Q, and the network device triggers one sensing group each time it sends the first information, and multiple transmissions of the first information sequentially trigger P sensing groups; or, N terminals belong to P sensing groups, where the first sensing group in the P sensing groups includes Q terminals, M = Q. The first information indicates the first sensing group; or, the first information indicates the identifiers of M terminals; or, the first information indicates the identifiers of M terminals and the number of times the M terminals repeatedly send or receive sensing signals, M = 1.

[0125] Optionally, in embodiments of this disclosure, "trigger terminal" can be used interchangeably with "scheduling terminal", and "trigger" and "scheduling" can be used interchangeably.

[0126] In other words, the specific method by which network devices schedule terminals using the first information is as follows.

[0127] Method 1

[0128] In some embodiments, N terminals belong to P sensing groups, M = a * P, where a ≥ 1 and is a positive integer. That is, the N terminals can be divided into P sensing groups, and the a terminals in each sensing group can be scheduled by sending the first information. For example, the terminals can be scheduled to send sensing signals.

[0129] Where a≥1 indicates that at least one terminal in each sensing group can be triggered.

[0130] In other words, sending the first message once can schedule at least one terminal in each sensing group; for example, a terminal can be scheduled to send a sensing signal.

[0131] In some embodiments, when the network device sends a sensing signal through the first information scheduling terminal, it can schedule at least one terminal in each sensing group at a time. The data of the terminals scheduled in each sensing group can be the same or different. For example, if there are 3 sensing groups and the network device needs to schedule 5 terminals, it can schedule 1 terminal in sensing group A, 1 terminal in sensing group B, 3 terminals in sensing group C, and so on. In this case, M = 1 + 1 + 3, meaning the total number of terminals scheduled is the sum of the number of terminals scheduled in each sensing group.

[0132] Method 2

[0133] In some embodiments, N terminals belong to P sensing groups, and the first sensing group in the P sensing groups includes Q terminals, M=Q. Each time the network device sends the first information, it triggers a sensing group. Multiple transmissions of the first information trigger the P sensing groups in sequence.

[0134] The first sensing group can be any of the P sensing groups. M = Q means that one first message can trigger all terminals in a sensing group to send sensing signals at the same time, and the first message can be sent multiple times to trigger the P sensing groups in sequence.

[0135] Method 3

[0136] In some embodiments, N terminals belong to P sensing groups, and the first sensing group among the P sensing groups includes Q terminals, where M = Q. The first information indicates the first sensing group.

[0137] The first sensing group can be any of the P sensing groups. M = Q means that one first information can simultaneously trigger all terminals in a sensing group to send sensing signals. The first information indicates the first sensing group, meaning that the network device can instruct and schedule all terminals in a specific sensing group to send sensing signals.

[0138] Specifically, the network device instructing the first sensing group through the first information may include the first information instructing the first sensing group by carrying an identifier of the first sensing group; or the first information instructing the first sensing group through resource configuration.

[0139] In the above embodiments, the first information can instruct the first sensing group through resource configuration. The correspondence between the sensing group and the time-frequency domain resources on which the terminal sends or receives sensing signals can be predetermined. For example, the network device can determine that P sensing groups send sensing signals on the same frequency domain resources but different time domain resources. That is, the network device configures different time domain resources for each sensing group, and different sensing groups share frequency domain resources.

[0140] For example, a network device can determine that P sensing groups send sensing signals on different frequency domain resources and the same time domain resources. That is, the network device configures different frequency domain resources for each sensing group, and different sensing groups share time domain resources.

[0141] For example, a network device can determine that P sensing groups send sensing signals on different frequency domain resources and different time domain resources. That is, the network device configures different frequency domain resources for each sensing group and different time domain resources for each sensing group.

[0142] In the above embodiments, after determining the correspondence between the sensing group and the resources, the network device can configure time-frequency domain resources for the terminal through the first information, and then all terminals in the sensing group corresponding to the time-frequency domain resources are scheduled to send sensing signals.

[0143] Method 4

[0144] In some embodiments, the first information may indicate the identifiers of M terminals.

[0145] In other words, a network device can schedule M terminals to send sensing signals by carrying the identifiers of M terminals in the first information. The M terminals may come from different sensing groups or the same sensing group, and this disclosure does not limit this.

[0146] Method 5

[0147] In some embodiments, the first information may indicate the identifiers of M terminals and the number of times the M terminals repeatedly transmit sensing signals, where M = 1.

[0148] In other words, the network device can use the first information to indicate a terminal to be scheduled, and the number of times the terminal is scheduled. The network device can use the first information to indicate a terminal to repeatedly send the sensing signal multiple times, that is, the number of times the terminal repeatedly sends the sensing signal.

[0149] Method 6

[0150] In some embodiments, N terminals belong to P sensing groups, M = a * P, where a ≥ 1 and is a positive integer. That is, the N terminals can be divided into P sensing groups, and the a terminals in each sensing group can be scheduled by sending the first information. For example, the terminals can be scheduled to receive sensing signals.

[0151] Where a≥1 indicates that at least one terminal in each sensing group can be triggered.

[0152] In other words, sending a first message can schedule at least one terminal within each sensing group; for example, a terminal can be scheduled to receive sensing signals.

[0153] In some embodiments, when a network device receives a sensing signal through a first information scheduling terminal, it can schedule at least one terminal in each sensing group at a time. The data of the terminals scheduled in each sensing group can be the same or different. For example, if there are 3 sensing groups and the network device needs to schedule 5 terminals, it can schedule 1 terminal in sensing group A, 1 terminal in sensing group B, 3 terminals in sensing group C, and so on. In this case, M = 1 + 1 + 3, meaning the total number of terminals scheduled is the sum of the number of terminals scheduled in each sensing group.

[0154] Method 7

[0155] In some embodiments, N terminals belong to P sensing groups, and the first sensing group in the P sensing groups includes Q terminals, M=Q. Each time the network device sends the first information, it triggers a sensing group. Multiple transmissions of the first information trigger the P sensing groups in sequence.

[0156] The first sensing group can be any of the P sensing groups. M = Q means that one first message can simultaneously trigger all terminals in a sensing group to receive sensing signals. The first message can be sent multiple times to trigger the P sensing groups in sequence.

[0157] Method 8

[0158] In some embodiments, N terminals belong to P sensing groups, and the first sensing group among the P sensing groups includes Q terminals, where M = Q. The first information indicates the first sensing group.

[0159] The first sensing group can be any of the P sensing groups. M = Q means that one first information can simultaneously trigger all terminals in a sensing group to receive sensing signals. The first information indicates the first sensing group, meaning that the network device can instruct and schedule all terminals in a specific sensing group to receive sensing signals.

[0160] Specifically, the network device instructing the first sensing group through the first information may include the first information instructing the first sensing group by carrying an identifier of the first sensing group; or the first information instructing the first sensing group through resource configuration.

[0161] In the above embodiments, the first information can instruct the first sensing group through resource configuration. The correspondence between the sensing group and the time-frequency domain resources on which the terminal sends or receives sensing signals can be predetermined. For example, the network device can determine that P sensing groups receive sensing signals on the same frequency domain resources and different time domain resources. That is, the network device configures different time domain resources for each sensing group, and different sensing groups share frequency domain resources.

[0162] For example, a network device can determine that P sensing groups receive sensing signals in different frequency domain resources and in the same time domain resources. That is, the network device configures different frequency domain resources for each sensing group and different sensing groups share time domain resources.

[0163] For example, a network device can determine that P sensing groups receive sensing signals in different frequency domain resources and different time domain resources. That is, the network device configures different frequency domain resources for each sensing group and different time domain resources for each sensing group.

[0164] In the above embodiments, after determining the correspondence between the sensing group and the resources, the network device can configure time-frequency domain resources for the terminal through the first information, and then all terminals in the sensing group corresponding to the time-frequency domain resources are scheduled to receive sensing signals.

[0165] Method 9

[0166] In some embodiments, the first information may indicate the identifiers of M terminals.

[0167] In other words, the network device can schedule M terminals to receive sensing signals by carrying the identifiers of M terminals in the first information. The M terminals may come from different sensing groups or the same sensing group, and this disclosure does not limit this.

[0168] Method 10

[0169] In some embodiments, the first information may indicate the identifiers of M terminals and the number of times the M terminals repeatedly receive the sensing signal, where M = 1.

[0170] In other words, the network device can use the first information to indicate a terminal to be scheduled, and the number of times the terminal is scheduled. The network device can use the first information to indicate a terminal to repeatedly receive sensing signals multiple times, that is, the number of times the terminal repeatedly receives sensing signals.

[0171] Step 2102: The terminal performs the first operation.

[0172] The terminal can perform a first operation based on the first information, wherein the first operation is: upon receiving the first information, incrementing the terminal's perception count value by 1; the first case being: the perception count value equals the terminal's perception group number; or the first operation is: upon receiving the first information, decrementing the terminal's perception count value by 1 from the initial perception count value; the first case being: the perception count value equals a first preset value; or the first operation is: upon receiving the first information, decrementing the terminal's perception group number by 1; the first case being: the perception group number equals a second preset value; or the first operation is: upon receiving the first information, incrementing the terminal's perception count value by 1; the first case being: the perception count value equals the identifier of the perception group to which the terminal belongs.

[0173] In some embodiments, when a network device schedules terminals in units of sensing groups via a first information instruction, it may perform a first operation, wherein the first information instruction to schedule terminals in units of sensing groups may include mode 1 and mode 2 in step 2101 above.

[0174] In other words, the specific way the terminal performs the first operation is as follows.

[0175] 1. The first information received by the terminal can be counted by the sensing count value. That is, when the first information is received, the sensing count value of the terminal is incremented by 1. Preferably, the initial sensing count value can be 0. When the number of sensing count values ​​is equal to the sensing group number of the terminal, it means that the terminal corresponding to the sensing group number is scheduled. At this time, the terminal can be scheduled.

[0176] 2. The first information received by the terminal can be counted by the sensing count value. That is, when the first information is received, the sensing count value of the terminal is decremented by 1 from the initial sensing count value. Preferably, the first preset value can be 0. That is, when the number of sensing count values ​​is equal to 0, the terminal is scheduled to send or receive sensing signals. At this time, the terminal can be scheduled.

[0177] For example, the first preset value can be predefined by the protocol.

[0178] 3. The first information received by the terminal can be counted by the sensing group number. That is, when the first information is received, the sensing group number of the terminal is decremented by 1. Preferably, the second preset value can be 0. That is, when the sensing group number is equal to 0, the terminal is scheduled to send or receive sensing signals. At this time, the terminal can be scheduled.

[0179] For example, the second preset value can be predefined by the protocol.

[0180] 4. The sensing group that needs to be scheduled can be determined by the sensing count value. That is, when the first information is received, the sensing count value of the terminal is incremented by 1. When the sensing count value is equal to the identifier of the sensing group to which the terminal belongs, the sensing group to which the terminal belongs can be scheduled.

[0181] In some embodiments, step 2102 is an optional step. For example, when the network device can directly indicate the identifier of the scheduled sensing group or the identifier of the scheduled terminal through the first information, the terminal can directly determine whether it is a scheduled terminal or belongs to the scheduled sensing group based on the first information, and this step can be omitted.

[0182] Step 2103: The terminal determines whether the first condition is met.

[0183] In some embodiments, the first case includes at least one of the following:

[0184] The perception count value of M terminals is equal to the perception group number of the M terminals, wherein the perception count value is incremented by 1 when the M terminals receive the first information;

[0185] The perception count value of M terminals is equal to the first preset value, wherein when the M terminals receive the first information, the perception count value is decremented by 1 from the initial perception count value;

[0186] The sensing group number of the M terminals is equal to the second preset value, wherein when the M terminals receive the first information, the sensing group number is decremented by 1.

[0187] The perception count value of M terminals is equal to the identifier of the perception group to which the M terminals belong, wherein the perception count value is incremented by 1 when the M terminals receive the first information;

[0188] The first information indicates the identifier of the sensing group to which the M terminals belong;

[0189] The first information indicates the resources for M terminals to send or receive sensing signals, and the resources are associated with the sensing group to which the terminals belong;

[0190] The first information indicates the identifiers of M terminals;

[0191] The first information indicates the identifiers of the M terminals and the number of times the M terminals repeatedly send or receive sensing signals.

[0192] Specifically, in the first case, the perception count value of M terminals is equal to the perception group number of M terminals. When the M terminals receive the first information, they increment the perception count value by 1, indicating that the first information can configure a perception count value and an initial perception count value for each terminal. Each terminal has a perception group number, which is the number of the terminal in the perception group. When the perception count value of a terminal is equal to the perception group number of the terminal, it can be indicated that the terminal is the terminal that needs to be scheduled in the current first information.

[0193] This allows for configuring different initial perception count values ​​for different terminals, or configuring different initial perception count values ​​for different terminals. For example, terminals within the same group can be configured with the same initial perception count value.

[0194] Specifically, when the first case is that the perception count value of M terminals is equal to the first preset value, where the perception count value is decremented by 1 from the initial perception count value when the M terminals receive the first information, it means that the first information can configure the perception count value and the initial perception count value for each terminal. Each time a terminal receives the first information, its corresponding perception count value is decremented by 1. For example, when the perception count value of a terminal is reduced to the first preset value, it can indicate that the terminal is scheduled to send or receive perception signals.

[0195] The first preset value can be predefined by the protocol, and preferably, the first preset value can be 0.

[0196] Specifically, in the first case, the sensing group number of M terminals is equal to the second preset value. When the M terminals receive the first information and decrement the sensing group number by 1, it means that the terminals can be directly scheduled according to the sensing group number of the terminal. The sensing group number is the number of the terminal in its sensing group. When the sensing group number of the terminal is reduced to 0, it means that the terminal is scheduled to send or receive sensing signals, and the terminal can be scheduled at this time.

[0197] The second preset value can be predefined by the protocol, and preferably, the second preset value can be 0.

[0198] Specifically, when the first case is that the perception count value of M terminals is equal to the identifier of the perception group to which the M terminals belong, and when the M terminals increment the perception count value by 1 when they receive the first information, it can be determined that the terminal is scheduled to send or receive perception signals when the terminal's perception count value is equal to the identifier of the perception group mentioned by the terminal. At this time, the terminals can be scheduled.

[0199] Specifically, when the first situation is that the first information indicates the identifier of the sensing group to which the M terminals belong, it can mean that the network device schedules the terminals by group. At this time, all or some of the terminals in the indicated sensing group can be scheduled, and the terminal can be scheduled to send or receive sensing signals.

[0200] Specifically, when the first situation is that the first information indicates the resources for M terminals to send or receive sensing signals, and the resources are associated with the sensing group to which the terminals belong, the terminals can be scheduled according to the association between the resources and the sensing group to which the terminals belong. In this case, the network device can determine that different terminals send or receive sensing signals on different time-frequency domain resources, so there is a correspondence between the terminals and the resources. The first information can indicate the time-frequency domain resources used by the terminals to send or receive signals. At this time, it can indirectly indicate the terminal corresponding to the resource, or the terminal that uses the resource to send or receive sensing signals, which is the terminal that the network device wants to schedule. At this time, the terminal can be scheduled to send or receive sensing signals on the time-frequency domain resources.

[0201] Specifically, when the first situation is that the first information indicates the identifiers of M terminals, it can mean that the network device can directly schedule specific terminals within different sensing groups.

[0202] Specifically, when the first situation is that the first information indicates the identifiers of M terminals and the number of times the M terminals repeatedly send or receive sensing signals, it can indicate that the terminal can schedule the specified terminal to repeatedly send or receive sensing signals, and can indicate the number of repetitions. Preferably, the value of M can be 1, that is, only one terminal is instructed to repeatedly send or receive sensing signals.

[0203] Step 2104: The network device sends a sensing signal to the terminal.

[0204] In some embodiments, the network device can send sensing signals to the terminal, at which time the network device schedules the corresponding terminal to receive the sensing signals.

[0205] In some embodiments, the network device may send sensing signals to M terminals, wherein the M terminals receive the sensing signals in a first case.

[0206] In other words, the network device can schedule M terminals to receive sensing signals when the first condition is met.

[0207] In some embodiments, this step is optional and can be omitted when the network device scheduling terminal sends a sensing signal.

[0208] Step 2105: The terminal sends a sensing signal to the network device.

[0209] In some embodiments, the network device may receive sensing signals sent by M terminals in a first situation.

[0210] In other words, network devices can schedule M terminals to send sensing signals in the first scenario.

[0211] In some embodiments, this step is optional and can be omitted when the network device scheduling terminal receives the sensing signal.

[0212] The method involved in the embodiments of this disclosure may include at least one of steps 2101 to 2105. For example, steps 2101+2102+2103+2104+2105 can be implemented as an independent embodiment, steps 2101+2102+2103+2104 can be implemented as an independent embodiment, and steps 2101+2102+2103+2105 can be implemented as an independent embodiment, but are not limited thereto.

[0367] 1. When a terminal device receives the first signaling sent by a network device, if it carries the terminal device's sensing group ID, the terminal device receives the sensing signal.

[0368] 2. When the terminal device receives the first signaling from the network device, the terminal device receives the sensing signal. (Consider distinguishing different sensing group IDs by sending different resources through the first signaling.)

[0369] Based on the above method, each time the network device triggers the sensing signal scheduling, it can trigger all terminal devices within at least one sensing group to receive the sensing signal. For example, if there are currently 8 sensing groups, the network device can schedule one or more of the 8 sensing groups at a time.

[0370] In one embodiment, a network device schedules at least one terminal device to receive sensing signals using the same frequency domain resources but different time domain resources. The network device sends sensing signals to at least one terminal device. The network device configures different time domain resources for each terminal device within each sensing group, while frequency domain resources are shared within the sensing group. The network device triggers sensing signal scheduling, and all terminal devices within at least one sensing group receive sensing signals.

[0371] In one embodiment, a network device schedules at least one terminal device to receive sensing signals using different frequency domain resources but the same time domain resources. The network device sends sensing signals to at least one terminal device. The network device configures different frequency domain resources for each terminal device within each sensing group, while sharing time domain resources within the sensing group. The network device triggers sensing signal scheduling, and all terminal devices within at least one sensing group receive sensing signals.

[0372] In one embodiment, a network device schedules at least one terminal device to receive sensing signals using different frequency domain resources and different time domain resources. The network device sends sensing signals to at least one terminal device. The network device configures different frequency domain resources for each terminal device within each sensing group, and different time domain resources for each terminal device within each sensing group. The network device triggers sensing signal scheduling, and all terminal devices within at least one sensing group receive sensing signals.

[0373] Example 9

[0374] In a network, network devices and terminal devices work together to perform sensing services. Terminal devices receive sensing signals, and network devices send sensing signals to the terminals. Network devices include at least one of base station equipment and core network equipment.

[0375] The protocol predefines at least one of the following: UE ID, number of retransmissions, and first signaling. The UE ID can be configured semi-statically or dynamically, meaning it includes at least one of the following: core network signaling configuration, RRC signaling configuration, MAC CE signaling configuration, and DCI signaling configuration. The first signaling includes at least one of the following: core network signaling, RRC signaling, MAC CE signaling, and DCI signaling.

[0376] The UE ID is a unique identifier for the scheduling terminal device.

[0377] The retransmission count indicates the number of times the terminal device receives the sensing signal.

[0378] The first signaling is used by network devices to trigger sensing signal scheduling, or in other words, to schedule at least one terminal device to receive sensing signals.

[0379] The network device triggers the reception of sensing signals through the first signaling, or in other words, schedules the terminal device to receive sensing signals in at least one of the following ways:

[0380] 1. When the terminal device receives the first signaling sent by the network device, if it carries the UE ID of the terminal device, the terminal device receives the sensing signal.

[0381] 2. When the terminal device receives the first signaling from the network device, the terminal device receives a sensing signal. (Consider using different resources to distinguish different UE IDs by sending the first signaling)

[0382] Based on the above method, the network device triggers the terminal device to receive the sensing signal through the first signal. For example, if there are currently 8 terminal devices, and the network device carries the UE IDs of terminal devices 1 and 4 through the first signaling, then 2 terminal devices will be scheduled at a time.

[0383] Example 10

[0384] In a network, network devices and terminal devices work together to perform sensing services. Terminal devices receive sensing signals, and network devices send sensing signals to the terminals. Network devices include at least one of base station devices and core network devices.

[0385] The protocol predefines at least one of the following: perception group, perception group ID, UE ID, repetition count, perception group sequence number, perception count, initial perception count value, and first signaling. The configuration methods for the aforementioned perception group, perception group ID, perception group sequence number, perception count, and initial perception count value include semi-static or dynamic methods, i.e., at least one of core network signaling configuration, RRC signaling configuration, MAC CE signaling configuration, and DCI signaling configuration. The aforementioned first signaling includes at least one of core network signaling, RRC signaling, MAC CE signaling, and DCI signaling.

[0386] The network device divides the terminal devices within its coverage area into at least one sensing group. Each sensing group includes at least one terminal device, and each sensing group corresponds to a sensing group ID. The network device can configure at least one sensing group ID for each terminal device. Preferably, each terminal device is configured with one sensing group ID, and secondly, it is configured with more than one sensing group ID.

[0387] The UE ID is a unique identifier for the scheduling terminal device.

[0388] The retransmission count indicates the number of times the terminal device receives the sensed signal.

[0389] The network device configures at least one of the following for each terminal device in each sensing group: sensing group number, sensing count, and initial sensing count value. The sensing group number indicates the scheduling order of the terminal within the corresponding sensing group. The sensing count determines the current sensing scheduling count value of the terminal. The initial sensing count value determines the initial sensing scheduling count value of the terminal.

[0390] The first signaling is used by the network device to trigger the reception of M sensing signals, or in other words, to schedule the terminal device to receive M sensing signals. The first signaling may include at least one of the following: sensing group, sensing group ID, sensing group sequence number, sensing count, initial value of sensing count, number of repetitions, and UE ID. The M is confirmed by a predefined protocol or indicated by the number of repetitions.

[0391] Based on the above method, the network device sends out the first signal, which will trigger M sensing signal scheduling.

[0392] In summary, the above embodiments of this solution can enable network devices to schedule terminals, thereby reducing scheduling signaling overhead.
