Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a method for measuring sensed signals, a terminal device, a network-side device, and a communication system. Background Technology

[0002] In related technologies, sensing signals are typically transmitted within a single time slot. Terminal devices can measure the sensing signals and provide feedback on the results. However, the speed resolution of the transmitting end of the sensing signal is limited by the duration of the sensing signal. Therefore, the sensing signal measurement methods in related technologies suffer from a technical problem: low speed resolution at the transmitting end of the sensing signal due to the limitation on its duration. Summary of the Invention

[0003] This application provides a method for measuring sensing signals, a terminal device, a network-side device, and a communication system to at least solve the technical problem in related technologies where the speed resolution of the sensing signal transmitter is low due to the limitation of the duration of the sensing signal.

[0004] According to one aspect of the embodiments of this application, a method for measuring a sensing signal is provided, applied to a terminal device. The method includes: continuously measuring the current sensing signal starting from the transmission start symbol of the current sensing signal, wherein the current sensing signal is a sensing signal transmitted across time slots; and periodically, semi-continuously, or non-periodically feeding back the phased measurement results of the current sensing signal during the transmission of the current sensing signal.

[0005] This embodiment utilizes cross-timeslot transmission of sensing signals, overcoming the limitation on the duration of sensing signals imposed by single-timeslot transmission. This increases the duration of the sensing signal, thereby improving the speed resolution at the transmitting end and addressing the problem of low speed resolution at the transmitting end in related technologies due to limitations in the duration of the sensing signal. Furthermore, continuous measurement during cross-timeslot transmission, with periodic, semi-continuous, or non-periodic feedback of phased measurement results, avoids the measurement delay caused by postponing measurement results after the sensing signal transmission is complete, thus shortening the measurement latency. Additionally, the transmission duration of the sensing signal can be controlled based on the phased measurement results, preventing resource waste.

[0006] In one exemplary embodiment, before continuously measuring the current sensed signal, the method further includes: sending capability indication information to the network side, wherein the capability indication information is used to indicate that the terminal device has the ability to provide feedback on interim measurement results during the transmission of the sensed signal.

[0007] Through this embodiment, the capability indication information reported by the terminal device enables the network side to identify which terminal devices support cross-time slot signal measurement and feedback, thereby configuring corresponding sensing tasks for these terminal devices and ensuring that other terminal devices operate according to their capabilities. The network side can make more accurate resource allocation and control decisions based on the capabilities of the terminal devices, avoid unnecessary signal transmission and processing, and enhance the system's resource utilization efficiency and performance.

[0008] In an exemplary embodiment, the periodic, semi-persistent, or non-periodic feedback of the phased measurement result of the current sensing signal includes: responding to each received downlink control information by feeding back the phased measurement result of the current sensing signal once, wherein each downlink control information is used to trigger the feedback of the measurement result once.

[0009] This embodiment utilizes downlink control information to trigger feedback of each stage measurement result, allowing the network side to dynamically control the feedback cycle based on the needs of different services or the real-time status of terminal devices. This provides a finer control granularity, enabling the network side to dynamically adjust the feedback frequency as needed to meet the perception requirements of different scenarios.

[0010] In an exemplary embodiment, responding to each received downlink control information, feeding back a phased measurement result of the current sensing signal once includes: responding to each received downlink control information, feeding back a phased measurement result corresponding to each downlink control information, wherein the phased measurement result corresponding to each downlink control information is a measurement result within the measurement interval corresponding to each downlink control information, wherein the measurement intervals corresponding to two adjacent downlink control information do not overlap or partially overlap; wherein the end position of the measurement interval corresponding to each downlink control information is one of the following: the time slot where each downlink control information is located; or the time slot preceding the time slot where each downlink control information is located; The m-th time slot or m-th symbol preceding the time slot containing each downlink control information, where m is one of the following: a predetermined value; the capability value reported by the terminal device to the network side; a value configured by the network side through higher-layer signaling or dynamic signaling; the feedback time slot of the phased measurement result corresponding to each downlink control information; the time slot preceding the feedback time slot of the phased measurement result corresponding to each downlink control information; the n-th time slot or n-th symbol preceding the feedback time slot of the phased measurement result corresponding to each downlink control information, where n is one of the following: a predetermined value; the capability value reported by the terminal device to the network side; a value configured by the network side through higher-layer signaling or dynamic signaling.

[0011] Through this embodiment, the flexible configuration of the end time of the measurement interval allows for the flexible configuration of a suitable measurement interval based on factors such as the processing capability of the terminal device. This avoids data redundancy and resource conflicts during feedback, ensuring the continuity and integrity of the measurement results and improving the effectiveness of network resource utilization.

[0012] In an exemplary embodiment, the starting position of the measurement interval corresponding to the first downlink control information is the transmission start symbol of the current sensing signal; the starting position of the measurement interval not corresponding to the first downlink control information is one of the following: the first symbol or the first time slot after the measurement interval corresponding to the previous downlink control information (not the first downlink control information); the first symbol or the first time slot after the feedback time slot of the stage measurement result corresponding to the previous downlink control information (not the first downlink control information); the first symbol or the first time slot after the time slot where the previous downlink control information (not the first downlink control information) is located.

[0013] By configuring the starting position of the measurement interval corresponding to the first downlink control information and the starting position of the measurement interval not corresponding to the first downlink control information in this embodiment, the flexibility of measurement result feedback can be improved while ensuring the integrity of the measurement result feedback.

[0014] In an exemplary embodiment, the periodic, semi-persistent, or non-periodic feedback of the phased measurement results of the current sensing signal includes: periodically feeding back the phased measurement results of the current sensing signal on time-frequency domain resources associated with the current sensing signal.

[0015] In this embodiment, the sensing signal and time-frequency domain resources are associated, and the phased measurement results are periodically fed back on the time-frequency domain resources associated with the sensing signal. For sensing signals transmitted across time slots, even if the signal spans multiple time slots, the continuity and integrity of the measurement can be ensured, and the sensing signal can be effectively tracked.

[0016] In an exemplary embodiment, before continuously measuring the current sensing signal starting from the transmission start symbol of the current sensing signal, the method further includes: receiving resource configuration information, wherein the resource configuration information is used to configure the association between the time-frequency domain resources of the sensing signal and the phased measurement results of the feedback sensing signal; and receiving first control information, wherein the first control information is used to indicate or activate the transmission of the current sensing signal.

[0017] In this embodiment, the resource configuration information informs the terminal device in advance of the correlation between the time and frequency resources to be used to send sensing signals and measurement results. Through precise configuration, resource waste can be avoided and timely data transmission can be ensured. By instructing or activating the transmission of sensing signals through the first control information, signal conflicts can be avoided caused by different network sides sending sensing signals to the terminal in the same time and frequency domain, thus reducing signal conflicts.

[0018] In one exemplary embodiment, the phased measurement result of the current sensing signal is automatically triggered in response to the first control information; or, the phased measurement result of the current sensing signal is triggered in response to received feedback trigger information, wherein the feedback trigger information is used to trigger periodic feedback of the phased measurement result of the current sensing signal.

[0019] In this embodiment, by automatically triggering the feedback of the phased measurement results through the first control information, the amount of control information that needs to be transmitted can be reduced, and the convenience of triggering the measurement result feedback can be improved; or, by triggering the feedback of the phased measurement results through separate feedback trigger information, unnecessary continuous measurement and feedback can be reduced, and the controllability of the phased measurement result feedback can be improved.

[0020] In one exemplary embodiment, before continuously measuring the current sensing signal starting from the transmission start symbol of the current sensing signal, the method further includes: receiving second control information, wherein the second control information is used to indicate or activate the transmission of the current sensing signal and to indicate time-frequency domain resources associated with the current sensing signal, and the phased measurement result of the current sensing signal is automatically triggered in response to the second control information.

[0021] In this embodiment, by activating the transmission of sensing signals, triggering the feedback of phased measurement results, and indicating the time-frequency domain resources associated with the sensing signals in a single information interaction, signaling overhead can be reduced, the utilization efficiency of wireless resources can be improved, and it is not necessary to wait for the reception of multiple independent control information before measuring and feeding back the sensing signals, thus reducing latency.

[0022] In an exemplary embodiment, the step of periodically feeding back the phased measurement results of the current sensing signal on the time-frequency domain resources associated with the current sensing signal includes: feeding back the phased measurement results of the current sensing signal once at a specified time slot on the time-frequency domain resources associated with the current sensing signal, wherein each fed-back phased measurement result of the current sensing signal is a measurement result that was measured before each time slot for feeding back the phased measurement results of the current sensing signal and has not been fed back.

[0023] In this embodiment, since each feedback is a previously measured result that has not been fed back, unnecessary repeated feedback is avoided, making the feedback process more efficient. At the same time, by feeding back the phased measurement results at specified time intervals, real-time monitoring and continuous tracking of the target can be achieved, improving the stability and reliability of the feedback.

[0024] In one exemplary embodiment, the time slot for the last feedback of the phase measurement result of the current sensing signal is located within the time slot occupied by the current sensing signal, or the time slot for the last feedback of the phase measurement result of the current sensing signal exceeds the last time slot occupied by the current sensing signal.

[0025] In this embodiment, the time slot of the last feedback is limited. For sensing tasks with extremely low latency requirements, the time slot of the last feedback can be set within the time slot occupied by the current sensing signal to reduce latency. The time slot of the last feedback exceeds the last time slot occupied by the sensing signal, thus separating the transmission time slot and feedback time slot of the sensing signal to avoid interference from the feedback to the sensing signal being transmitted, thereby improving the quality and reliability of the feedback.

[0026] In one exemplary embodiment, the current sensing signal is sent from the network side to the terminal device, or the current sensing signal is sent and received by the terminal device itself, or the current sensing signal is sent to the terminal device by other devices.

[0027] This embodiment employs one of the following application modes for sensing signal measurement: network-side transmission and terminal device reception, self-transmission and self-reception by the terminal device, transmission and reception between different terminal devices, which can adapt to different usage scenarios and thus improve the adaptability of sensing signal measurement.

[0028] According to another aspect of the embodiments of this application, a method for measuring a sensing signal is provided, applied to a network-side device. The method includes: sending a current sensing signal to a terminal device, wherein the current sensing signal is a sensing signal transmitted across time slots; and during the transmission of the current sensing signal, receiving periodic measurement results of the current sensing signal from the terminal device, either periodically, semi-persistently, or non-periodically.

[0029] This embodiment utilizes cross-timeslot transmission of sensing signals, overcoming the limitation on the duration of sensing signals imposed by single-timeslot transmission. This increases the duration of sensing signals, thereby improving the speed resolution at the transmitting end. Furthermore, continuous measurement during cross-timeslot transmission, with periodic, semi-continuous, or non-periodic feedback of phased measurement results, avoids the measurement delay caused by feedback after signal transmission, thus shortening the measurement latency. Additionally, the transmission duration can be controlled based on phased measurement results, preventing resource waste.

[0030] In one exemplary embodiment, before sending the current sensing signal to the terminal device, the method further includes: receiving capability indication information reported by the terminal device, wherein the capability indication information is used to indicate that the terminal device has the capability to provide feedback on phased measurement results during the transmission of the sensing signal.

[0031] In this embodiment, the capability indication information reported by the terminal device enables the network side to identify which terminal devices support cross-timeslot signal measurement and feedback, thereby configuring corresponding sensing tasks for these terminal devices. Simultaneously, it ensures that other terminal devices operate according to their capabilities. The network side can make more precise resource allocation and control decisions based on the capabilities of the terminal devices, avoiding unnecessary signal transmission and processing, and enhancing the system's resource utilization efficiency and performance. In an exemplary embodiment, the method further includes: during the transmission of the current sensing signal, sending multiple downlink control messages to the terminal device, wherein each downlink control message triggers the terminal device to feed back a phased measurement result of the current sensing signal.

[0032] This embodiment utilizes downlink control information to trigger the feedback of each staged measurement result, allowing the network side to dynamically control the feedback cycle based on the needs of different services or the real-time status of terminal devices. This provides finer control granularity, enabling the network side to dynamically adjust the feedback frequency as needed to meet the sensing requirements in different scenarios. In an exemplary embodiment, the staged measurement result of the current sensing signal is periodically fed back on time-frequency domain resources associated with the current sensing signal. Before sending the current sensing signal to the terminal device, the method further includes one of the following: sending resource configuration information to the terminal device, wherein the resource configuration information is used to configure the association relationship between the sensing signal and the time-frequency domain resources of the staged measurement result of the feedback sensing signal; sending first control information to the terminal device, wherein the first control information is used to indicate or activate the transmission of the current sensing signal; sending second control information to the terminal device, wherein the second control information is used to indicate or activate the transmission of the current sensing signal and indicate the time-frequency domain resources associated with the current sensing signal, and the staged measurement result of the current sensing signal is automatically triggered by the terminal device in response to the second control information.

[0033] In this embodiment, by pre-informing the terminal device of the association between time-frequency resources to be used for transmitting sensing signals and measurement results through resource configuration information, resource waste can be avoided and timely data transmission can be ensured through precise configuration. By instructing or activating the transmission of sensing signals through the first control information, signal conflicts caused by different network sides transmitting sensing signals to the terminal in the same time-frequency domain can be avoided, thus reducing signal conflicts. By automatically triggering the feedback of phased measurement results through the first control information, the required control information to be transmitted can be reduced, improving the convenience of triggering the feedback of measurement results. Alternatively, by triggering the feedback of phased measurement results through separate feedback trigger information, unnecessary continuous measurement and feedback can be reduced, improving the controllability of phased measurement result feedback. By using the second control information to simultaneously activate the transmission of sensing signals, trigger the feedback of phased measurement results, and indicate the time-frequency domain resources associated with the sensing signals through a single information interaction, signaling overhead can be reduced, the utilization efficiency of wireless resources can be improved, and it is not necessary to wait for the reception of multiple independent control information before the measurement and feedback of sensing signals can be performed, thus reducing latency. In an exemplary embodiment, the method further includes: in response to the received phased measurement results of the current sensing signal, stopping the transmission of the current sensing signal to the terminal device.

[0034] This embodiment allows for timely response to feedback of phased measurement results after receiving the current sensing signal's interim measurement results, avoiding resource waste and unnecessary interference with other data transmissions.

[0053] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0054] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0055] According to one aspect of the embodiments of this application, a method for measuring a sensed signal is provided. Optionally, in this embodiment, the above-described method for measuring a sensed signal may be applied, but is not limited to, to applications such as... Figure 1 The hardware environment shown includes terminal device 102 and network-side device 104. Network-side device 104 can communicate with terminal device 102 and can be used to provide services (e.g., application services, etc.) to terminal device 102 or clients installed on terminal device 102. A database can be set up on or independently of network-side device 104 to provide data storage services for network-side device 104.

[0056] Terminal device 102 may be, but is not limited to, personal computers (PCs), mobile phones, tablets, etc. Network-side device 104 may be, but is not limited to, base stations, core network nodes, edge computing nodes, etc.

[0057] The method for measuring the sensed signal in this embodiment can be executed by the network-side device 104, the terminal device 102, or jointly by both. Alternatively, the method for measuring the sensed signal in this embodiment can be executed by a client installed on the terminal device 102.

[0058] Optionally, the sensing signal measurement method in this embodiment can be applied to the field of communications, specifically to detection and tracking scenarios. In the tracking scenario, the terminal device measures the sensing signal and provides feedback on the measurement result within a single time slot. This feedback result can serve as the basis for control decisions. In this scenario, the measurement result within a single time slot is too short to predict the motion trend of the terminal device, leading to discontinuous tracking. Furthermore, the short measurement time results in low velocity resolution. Additionally, the fact that the measurement result can only be fed back after the sensing signal is sent prolongs the measurement time and causes tracking lag.

[0059] For example, the performance of velocity estimation is related to the duration of the sensed signal and the temporal density. For monostatic sensing (where the transmission and reception of the sensed signal are both completed in the same device (base)) and bistatic sensing (involving two different bases (devices), one used as the signal transmitter and the other as the signal receiver), the relationship between performance and sensed signal can be shown in Table 1.

[0060] Table 1

[0061]

[0062] In bistatic sensing, B is the signal bandwidth, c is the speed of light, β is the bistatic angle, and f is the bistatic angle. c With the center frequency, T d λ is the signal duration, d is the antenna spacing, N is the number of receiving antennas, θ is the target angle, Δf is the frequency domain sampling interval, and ΔT is the time domain sampling interval.

[0063] As can be seen from Table 1, the velocity resolution is related to the duration of the sensed signal; the longer the duration of the sensed signal, the more accurate the velocity resolution.

[0064] To at least partially address the aforementioned technical problems, this embodiment employs a cross-timeslot transmission of the sensing signal. This overcomes the limitation on the duration of the sensing signal imposed by single-timeslot transmission, increasing the duration of the sensing signal and thus improving the speed resolution at the transmitting end. Furthermore, continuous measurement during the cross-timeslot transmission of the sensing signal, along with periodic, semi-continuous, or non-periodic feedback of the phased measurement results, avoids the measurement delay caused by feeding back the measurement results after the sensing signal transmission is complete, thereby shortening the measurement latency. Additionally, the transmission duration of the sensing signal can be controlled based on the phased measurement results, preventing resource waste.

[0065] It should be noted that there is a potential demand for long-frame structure sensing signals (sense signals spanning time slots or frames) from both performance and business requirements perspectives. On the one hand, referring to Table 1, from the perspective of sensing performance, there is a demand for sensing signals with long durations spanning time slots. On the other hand, sensing services can be divided into two categories: detection and tracking. Tracking services require tracking of the sensing target for a certain duration, which also creates a certain demand for sensing signals spanning time slots.

[0066] Taking the measurement method of the sensed signal in this embodiment executed by terminal device 102 as an example, Figure 2 This is a flowchart of the steps of an optional sensing signal measurement method according to an embodiment of this application, as follows: Figure 2 As shown, the process of this method may include the following steps:

[0067] Step S202: Starting from the transmission start symbol of the current sensing signal, continuously measure the current sensing signal, where the current sensing signal is a sensing signal transmitted across time slots;

[0068] Step S204: During the current sensing signal transmission process, periodically, semi-continuously, or non-periodically, the phased measurement results of the current sensing signal are fed back.

[0069] Sensing signals are special signals actively transmitted or passively received by communication or sensing systems for detecting, measuring, and understanding the state of wireless channels or the characteristics of the physical environment. Sensing signals include synchronization signals, reference signals, broadcast signals, etc., which are not limited to these in this embodiment. Sensing signals can also be called sensing reference signals, and the time-frequency domain resources for transmitting sensing signals can be called sensing signal resources or sensing parameter signal resources. Sensing signals can be periodic, semi-continuous, or aperiodic. During the transmission of sensing signals, the terminal device can perform sensing signal measurements and feed back the measurement results or interim measurement results to the transmitting end or designated end of the sensing signal.

[0070] The current sensing signal is the sensing signal currently received by the terminal device. If the current sensing signal is a time-slot-transmitted signal, the terminal device can continuously measure the current sensing signal starting from its transmission start symbol. A time-slot-transmitted sensing signal refers to a sensing signal transmitted over multiple consecutive or non-consecutive time slots. The more time slots the sensing signal occupies, the longer its duration. A time slot refers to a fixed-length time segment with clearly defined start and end boundaries during communication. A time slot can be evenly divided into several consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols, typically numbered from 0 within a time slot. Each OFDM symbol has a corresponding index number, and the OFDM symbol is equivalent to the basic time unit of a time slot. The transmission start symbol of the current sensing signal refers to the first symbol of the current sensing signal, which can be the index number of the first OFDM symbol occupied by the sensing signal in a time slot.

[0071] Currently, reference signals in New Radio (NR), such as the Synchronization Signal Block (SSB), Sounding Reference Signal (SRS), and Channel State Information Reference Signal (CSI-RS), confine a signal resource within a single time slot, rarely spanning multiple time slots. For these reference signals, the measurement results are typically fed back after the terminal device has measured the complete sensed signal; that is, a one-time feedback is provided.

[0072] When a sensing signal resource spans multiple time slots, the approach of processing the signal after receiving it may no longer be applicable. If a one-time feedback method is used, the terminal device needs to provide a measurement result after the sensing signal transmission is complete. This feedback has a long delay, poor flexibility, and may not be suitable for application scenarios involving sensing signals spanning multiple time slots, thus wasting resources.

[0073] In this embodiment, during the current sensing signal transmission process, the terminal device can periodically, semi-continuously, or non-periodically provide feedback on the phased measurement results of the current sensing signal. Here, the phased measurement results refer to the measurement results obtained by partially measuring the current sensing signal (the measurement results of the sensing signal within a certain measurement interval). Providing phased feedback on a portion of the sensing signal, instead of waiting for the sensing signal to be completely transmitted, can reduce feedback latency.

[0074] Interim measurement results are not limited to feedback channel status information; they can be transformed into requests or suggestions to adjust and guide the targeted transmission of subsequent sensing signals. Feedback of the current sensing signal's interim measurement results can be periodic, semi-continuous, or aperiodic. Periodic feedback can be triggered by a fixed timer and follow a fixed reporting cycle. Semi-continuous feedback can be periodic or aperiodic for a period of time, the end of which can be related to the duration of the sensing signal. Aperiodic feedback can be triggered by receiving dynamic commands or other events; since these events are typically aperiodic, the feedback of interim measurement results is also aperiodic.

[0075] Here, semi-persistent feedback refers to a feedback method with a limited feedback duration, which can be a form of periodic or aperiodic feedback. Semi-persistent feedback can include semi-persistent periodic feedback and semi-persistent aperiodic feedback. Semi-persistent periodic feedback refers to periodic feedback of phased measurement results for a period of time, and the duration of the feedback is related to the duration of the sensed signal. Semi-persistent aperiodic feedback refers to aperiodic feedback of phased measurement results for a period of time, and the duration of the feedback is related to the duration of the sensed signal.

[0076] For the transmitting end or designated end of the current sensing signal, after receiving the interim feedback result, it can parse the received interim feedback result and determine whether to continue transmitting the current sensing signal based on the parsing result, or to execute other decisions. This embodiment does not limit this. Optionally, after the terminal device feeds back the interim measurement result, the network side can stop transmitting the next sensing signal.

[0077] The embodiments provided in this application utilize cross-timeslot transmission of sensing signals, overcoming the limitation on the duration of sensing signals imposed by single-timeslot transmission. This achieves the goal of increasing the duration of sensing signals, thereby improving the speed resolution at the transmitting end of the sensing signal. This solves the problem in related technologies where sensing signal measurement methods suffer from low speed resolution at the transmitting end due to limitations in the duration of the sensing signal. Furthermore, continuous measurement during cross-timeslot transmission of the sensing signal, along with periodic, semi-continuous, or non-periodic feedback of the phased measurement results, avoids the measurement delay caused by feeding back the measurement results after the sensing signal transmission is complete, thus shortening the measurement delay. Additionally, the transmission duration of the sensing signal can be controlled based on the phased measurement results, preventing resource waste.

[0078] In one exemplary embodiment, the sensing mode of the sensing signal can be multiple, including but not limited to at least one of the following three sensing modes: a first sensing mode, in which the network side sends the sensing signal and the terminal device receives it (e.g., the base station sends and the UE receives); a second sensing mode, in which the terminal device sends and receives the sensing signal itself (e.g., the UE sends and receives it itself); and a third sensing mode, in which one terminal device sends the sensing signal and another terminal device receives the sensing signal (e.g., one UE sends and another UE receives it). Appropriate sensing modes can be used based on different usage scenarios. The current sensing signal can be sent from the network side to the terminal device, or it can be sent and received by the terminal device itself, or it can be sent from another device (another terminal device) to the terminal device (the current terminal device).

[0079] Here, the network side can refer to base stations, core network nodes, and edge computing nodes in potential edge computing platforms. The first sensing mode can be applied to large-scale environmental sensing, terminal device positioning, and terminal device navigation. By analyzing and processing the measurement results fed back by the sensing signals from the terminal device, the corresponding location information and status information of the terminal device can be obtained, thereby realizing functions such as environmental sensing, positioning, and navigation.

[0080] The first sensing mode involves the terminal device simultaneously transmitting and receiving signals, meaning that the same terminal device acts as both a transmitter and receiver, sensing the physical world by analyzing the environmental echoes of its own transmitted signals. This second sensing mode can be applied to scenarios such as contactless gesture recognition, autonomous driving, and equipment security.

[0081] The transmission of sensing signals from other devices to terminal devices can include the transmission of sensing signals from terminal device A to terminal device B. The transmission and reception of sensing signals no longer rely on central nodes and base stations, directly realizing short-range information exchange and collaboration between terminal devices. The third sensing mode can be applied to application scenarios such as vehicle relative state perception, drone swarms, and industrial IoT. Terminal devices measure information such as distance and speed of another terminal device relative to themselves by sending and receiving sensing signals from each other, thereby realizing the above application scenarios.

[0082] Optionally, during the transmission and reception of sensing signals, in order to avoid signal interference and multipath effects in the environment, anti-interference technology can be used to ensure the clarity of the sensing signals. At the same time, in order to ensure the security of feedback, encryption technology can be used to ensure the security of information.

[0083] This embodiment employs one of the following application modes for sensing signal measurement: network-side transmission and terminal device reception, self-transmission and self-reception by the terminal device, transmission and reception between different terminal devices, which can adapt to different usage scenarios and thus improve the adaptability of sensing signal measurement.

[0084] In one exemplary embodiment, the sensing signal may be sent from the network side to the terminal device, or it may be sent from the network side to the terminal device itself or from other terminal devices. Before the sensing signal is sent, the network side is unaware of whether the terminal device supports cross-timeslot measurement and feedback. If the terminal device does not support cross-timeslot measurement and feedback, it cannot provide feedback during the transmission of the sensing signal, and the transmission and feedback of the sensing signal cannot meet the requirements, thus reducing the effectiveness of signal transmission.

[0085] To improve the effectiveness of sensing signal transmission, in this embodiment, the terminal device can indicate whether it supports cross-timeslot signal measurement and feedback through capability indication information. Correspondingly, before continuously measuring the current sensing signal, the method further includes sending capability indication information to the network side. This capability indication information can be used to indicate that the terminal device has the ability to provide feedback on interim measurement results during sensing signal transmission. The capability indication information can be carried by RRC signaling.

[0086] The network side comprises a series of infrastructure and systems that provide communication services to terminal devices, including but not limited to base stations, antenna systems, fronthaul / backhaul / midhaul equipment, and server clusters. Terminal devices can send capability indication information to the network side to indicate their ability to provide feedback on interim measurement results during signal transmission. Based on the capability indication information reported by the terminal devices, the network side can identify which terminal devices support cross-timeslot signal measurement and feedback, thereby configuring appropriate sensing tasks for these devices while ensuring that other terminal devices operate according to their capabilities.

[0087] It should be noted that capability indication information is descriptive information reported by the communication device to the network side regarding its supported hardware characteristics, software functions, protocol versions, and performance parameters. This ensures that the network side can customize appropriate service configurations based on the actual capabilities of the terminal device and issue instructions that the terminal device cannot execute. In this embodiment, the capability indication information can be used to provide feedback to the terminal device that it possesses the ability to provide interim measurement results during the transmission of sensing signals, thereby ensuring that the terminal device receiving sensing signals transmitted across time slots can provide interim measurement results during the transmission of sensing signals.

[0088] For example, a user equipment (UE) capable of providing feedback during the transmission of a sensing reference signal can initially report its capability to the network side via higher-layer signaling.

[0089] Through this embodiment, the capability indication information reported by the terminal device enables the network side to identify which terminal devices support cross-time slot signal measurement and feedback, thereby configuring corresponding sensing tasks for these terminal devices and ensuring that other terminal devices operate according to their capabilities. The network side can make more accurate resource allocation and control decisions based on the capabilities of the terminal devices, avoid unnecessary signal transmission and processing, and enhance the system's resource utilization efficiency and performance.

[0090] In an exemplary embodiment, for sensing signals spanning multiple time slots or even multiple radio frames, aperiodic sensing information feedback can be triggered during the transmission of a sensing signal. Optionally, in this embodiment, aperiodic feedback can be triggered by dynamic commands. These dynamic commands can be one or more types, including but not limited to downlink control information (DCI) triggering aperiodic feedback, or semi-persistent feedback triggered by DCI or a medium access control element (MAC-CE). Correspondingly, periodic, semi-persistent, or aperiodic feedback of the current sensing signal's phased measurement results includes: responding to each received downlink control information by feeding back the current sensing signal's phased measurement result once.

[0091] Downlink control information is a dynamic scheduling instruction sent by the network side to the terminal device through the physical downlink control channel. It can be used to instruct the terminal device on the time, location, and method of receiving downlink data, or to instruct the terminal device on the time, location, and method of sending uplink data. In this embodiment, each downlink control message can trigger a feedback of a measurement result; that is, upon receiving each downlink control message, the terminal device provides feedback on a phased measurement result. Through this method, the network side can control the feedback frequency and other parameters based on different application scenarios and communication conditions using downlink control information. For example, in a dense communication network, to avoid interference from other devices, the network side can adjust the feedback frequency and timing based on the phased measurement results using downlink control information.

[0092] For example, the network side can instruct the terminal device to provide feedback on the measurement based on the sensing reference signal and provide sensing information (i.e., phased measurement results) during the transmission of a sensing reference signal via higher-layer signaling, DCI, or MAC-CE. The higher-layer signaling, DCI, or MAC-CE may include at least one of the following information: interval or periodicity information for the feedback sensing information; the time interval between the first feedback sensing information and the higher-layer signaling, DCI, or MAC-CE; the time interval between the first feedback sensing information after the higher-layer signaling, DCI, or MAC-CE and the higher-layer signaling, DCI, or MAC-CE; Physical Uplink Control Channel (PUCCH) resource information for the feedback sensing information; Physical Uplink Shared Channel (PUSCH) resource configuration information for the feedback sensing information; the type of feedback sensing information (e.g., distance, location, angle, speed, etc.); the number of feedback sensing information occurrences; power control information of the channel carrying the feedback sensing information; and Transmission Configuration Indication (TCI) information of the channel carrying the feedback sensing information. The PUSCH resource configuration information in the feedback sensing information may include at least one of the following: PUSCH resource periodicity; PUSCH time-domain resource information; PUSCH frequency-domain resource information; PUSCH modulation and coding scheme (MCS) information; PUSCH TCI information; and PUSCH power control information. The PUCCH resource configuration information in the feedback sensing information may include at least one of the following: PUCCH resource periodicity; PUCCH time-domain resource information; PUCCH frequency-domain resource information; PUCCH MCS information; PUCCH TCI information; and PUCCH power control information.

[0093] Optionally, the higher-layer signaling, DCI, or MAC-CE transmitted by the network side that triggers the terminal device to send or receive sensing reference signals may include at least one of the following information: interval or periodic information of feedback sensing information; time interval between the first feedback sensing information and the higher-layer signaling, DCI, or MAC-CE; time interval between the first feedback sensing information after the higher-layer signaling, DCI, or MAC-CE and the higher-layer signaling, DCI, or MAC-CE; PUCCH resource information of feedback sensing information; PUSCH resource configuration information of feedback sensing information; type of feedback sensing information (e.g., distance, location, angle, velocity, etc.); number of feedback sensing information; power control information of the channel carrying the feedback sensing information; and TCI information of the channel carrying the feedback sensing information. The PUSCH resource configuration information of the feedback sensing information may include at least one of the following information: periodic information of PUSCH resources; time-domain resource information of PUSCH; frequency-domain resource information of PUSCH; MCS information of PUSCH; TCI information of PUSCH; and power control information of PUSCH. The PUCCH resource configuration information for feedback sensing may include at least one of the following: PUCCH resource periodic information; PUCCH time-domain resource information; PUCCH frequency-domain resource information; PUCCH MCS information; PUCCH TCI information; PUCCH power control information.

[0094] This embodiment utilizes downlink control information to trigger feedback of each stage measurement result, allowing the network side to dynamically control the feedback cycle based on the needs of different services or the real-time status of terminal devices. This provides a finer control granularity, enabling the network side to dynamically adjust the feedback frequency as needed to meet the perception requirements of different scenarios.

[0095] In an exemplary embodiment, to accommodate different measurement requirements and network conditions, the measurement interval corresponding to each reported interim measurement result can be defined. Correspondingly, in response to each received downlink control information, the interim measurement result corresponding to each downlink control information is fed back, wherein the interim measurement result corresponding to each downlink control information is the measurement result within the measurement interval corresponding to each downlink control information, and the measurement intervals corresponding to two adjacent downlink control information do not overlap or partially overlap.

[0096] Optionally, the number of times the sensing information required for the cross-timeslot sensing signal needs to be fed back can be determined by predefinition or by the network side through higher-layer signaling configuration. For example, there can be a correspondence between the number of timeslots spanned by the cross-timeslot sensing signal and the number of times sensing information needs to be fed back. For instance, if the cross-timeslot sensing signal spans 8 timeslots, it can be predefined that it needs to feed back sensing information 4 times. Optionally, the channel used to feed back multiple sensing information can correspond to different PUCCH resources or semi-persistent PUCCH resources.

[0097] In this embodiment, the feedback triggered by each downlink control information is the phased measurement result corresponding to that downlink control information, that is, the measurement result within the measurement interval corresponding to each downlink control information. The measurement interval corresponding to a downlink control information can correspond to the reception time slot of that downlink control information. The end time of the measurement interval corresponding to a downlink control information can be flexibly configured according to different feedback requirements.

[0098] As an optional implementation, the end position of the measurement interval corresponding to each downlink control information can be the time slot where each downlink control information is located. The reported phased measurement result corresponding to each downlink control information can be the measurement result up to the time slot where each downlink control information is located. The end position of the measurement interval and the time slot for feedback of phased measurement results are the same time slot, which can reduce the time delay of sensing signal feedback.

[0099] As an alternative implementation, the end position of the measurement interval corresponding to each downlink control information can be the time slot preceding the time slot in which each downlink control information is located. The phased measurement result corresponding to each downlink control information reported can be the measurement result of the time slot preceding the time slot in which each downlink control information is located. This gives the terminal device time to process the phased measurement results, enabling even terminal devices with weaker processing capabilities to complete complex channel estimation and channel state information (CSI) calculations, reducing the implementation requirements of the network side and terminal devices, thereby reducing deployment costs.

[0100] As another optional implementation, the end position of the measurement interval corresponding to each downlink control information can be the m-th time slot or the m-th symbol before the time slot where each downlink control information is located, where m is a natural number greater than or equal to 2, and its value can be determined based on the capability value of the terminal device. The capability value of the terminal device can be used to represent the feedback capability of the terminal device to the sensed signal. When the capability value is larger, it indicates that the feedback capability of the terminal device is stronger, and the terminal device can generate the interim measurement result in a shorter time. In this case, the value of m can be set smaller. When the capability value is smaller, it indicates that the feedback capability of the terminal device is weaker, and the terminal device needs a longer time to generate the interim measurement result. In this case, the value of m can be set larger.

[0101] As another optional implementation, the end position of the measurement interval corresponding to each downlink control information can be the feedback time slot of the phased measurement result corresponding to each downlink control information. That is, the feedback continues until the phased measurement result is sent in the time slot where the phased feedback result is located. This can reduce measurement delay while ensuring the integrity of the phased measurement result.

[0102] As another optional implementation, the end position of the measurement interval corresponding to each downlink control information can be one time slot before the feedback time slot of the phased measurement result corresponding to each downlink control information. That is, the feedback continues until the phased measurement result in the time slot preceding the time slot where the phased feedback result is to be sent. In this way, the timeliness of the phased measurement result feedback can be ensured while reducing the processing power requirements of the terminal equipment.

[0103] As another optional implementation, the end position of the measurement interval corresponding to each downlink control information can be the nth time slot or the nth symbol before the feedback time slot of the phased measurement result corresponding to each downlink control information, where n is a natural number greater than or equal to 2, and its value can be determined based on the capability value of the terminal device. Here, the method for determining the value of n is the same as or similar to the method for determining the value of m. n and m can be the same or different, and this embodiment does not limit this. The values ​​of m or n can be determined by a predefined method, configured by the network side through RRC, DCI, or MAC-CE, or reported by the UE through higher-layer signaling.

[0104] Through this embodiment, the flexible configuration of the end time of the measurement interval allows for the flexible configuration of a suitable measurement interval based on factors such as the processing capability of the terminal device. This avoids data redundancy and resource conflicts during feedback, ensuring the continuity and integrity of the measurement results and improving the effectiveness of network resource utilization.

[0105] In one exemplary embodiment, the starting position of the measurement interval corresponding to the first downlink control information can be a symbol following the transmission start symbol of the current sensing signal. To ensure the integrity of signal measurement, the starting position of the measurement interval corresponding to the sensing information feedback triggered by the first downlink control information can be the transmission start symbol of the current sensing signal. For the starting position of the measurement interval corresponding to the sensing information feedback not triggered by the first downlink control information, it can be the first symbol or the first time slot following the end position of the measurement interval corresponding to the previous downlink control information. To improve the flexibility of measurement result feedback, in this embodiment, the end position of the measurement interval corresponding to the sensing information feedback not triggered by the first downlink control information can be flexibly set.

[0106] As an optional implementation, the starting position of the measurement interval corresponding to a non-first downlink control information can be the first symbol or the first time slot after the measurement interval corresponding to the previous downlink control information. Through the above implementation, the continuity of the sensing process can be maintained, information acquisition gaps can be avoided, complete measurement and feedback of the sensed signal can be achieved, and the integrity of signal measurement and feedback can be improved. Furthermore, the measurement window can be quickly restarted, which helps to reduce delays in the feedback loop, thereby enabling faster response to environmental changes.

[0107] As an alternative implementation, the starting position of the measurement interval corresponding to a non-first downlink control information can be the first symbol or the first time slot after the feedback time slot of the stage measurement result corresponding to the previous downlink control information. This implementation helps establish a clear time reference, facilitating signal processing and data analysis. Furthermore, time slot boundaries are usually accompanied by resource resets, and starting measurement from the first symbol of the new time slot can reduce interference from the residual effect at the tail of the previous time slot. In addition, using the time slot boundary as the measurement starting point simplifies the signal synchronization process and reduces the risk of synchronization errors between the transmitting and receiving sides.

[0108] As another optional implementation, the starting position of the measurement interval corresponding to a non-first downlink control information can be the first symbol or the first time slot after the time slot of the previous downlink control information. Through the above implementation, the measurement cycle of the sensing signal is allowed to be directly controlled by the downlink control information, enabling rapid response in changing environments and enhancing the dynamic adaptability of measurement result feedback. Furthermore, by closely linking the measurement start point with the downlink control information, more refined feedback control is achieved, allowing dynamic adjustment of the measurement frequency and range according to network requirements. In addition, the downlink control information can contain the latest information on the allocation of sensing signal resources; initiating measurement based on this information enables the terminal device to adopt the optimal sensing strategy, improving the accuracy of the sensing results.

[0109] For example, combining Figure 3 and Figure 4 (exist Figure 3 and Figure 4 In this diagram, each rectangle represents one time slot, and a sensing reference signal (i.e., a sensing signal) spans multiple time slots. Within each time slot, the number of symbols occupied by a sensing reference signal can be all the symbols within the time slot, or one or more symbols (contiguous or discontinuous) within the time slot. Furthermore, within different time slots, the symbols occupied by the same sensing signal resource can be symbols at the same location or symbols at different locations.

[0110] Based on the protocol specifications, the measurement interval of the sensing reference signal can be selected from several options. Specifically, for the first sensing information feedback occurring during the transmission of a sensing reference signal, the corresponding measurement interval can be selected from the following six options:

[0111] Choose option 1, starting from the transmission start symbol of the sensing reference signal until the time slot where the DCI triggers the feedback sensing information, such as Figure 3 and Figure 4 Measurement range-1 in the measurement range;

[0112] Option 2, starting from the transmission start symbol of the sensing reference signal until the time slot preceding the DCI that triggers the feedback sensing information, such as... Figure 3 and Figure 4 Measurement range -3;

[0113] Option 3: Starting from the transmission start symbol of the sensing reference signal until the mth time slot or mth symbol before the DCI that triggers the feedback sensing information, where m can be a predefined value, a capability value reported by the UE to the network-side device, or a value configured by the network-side device to the UE through higher-layer signaling or dynamic signaling.

[0114] Option 4 starts from the transmission start symbol of the sensing reference signal until the time slot where the feedback sensing information is located, such as... Figure 3 and Figure 4 Measurement range-2 in the measurement range;

[0115] Option 5: Start from the transmission start symbol of the sensing reference signal until the time slot before the time slot where the feedback sensing information is located;

[0116] Option 6: Starting from the transmission start symbol of the sensing reference signal until the nth time slot or the nth symbol before the time slot where the feedback sensing information is located, where n can be a predefined value, a capability value reported by the UE to the network-side device, or a value configured by the network-side device to the UE through higher-layer signaling or dynamic signaling. m and n can be the same or different.

[0117] For a non-first sensing information feedback that occurs during the transmission of a sensing reference signal, its corresponding measurement interval can inherit the above 6 options, and has the following choices:

[0118] Choose 7, starting from the measurement sensing signal interval corresponding to the last feedback sensing information (the first symbol or the first time slot) until the end position determined by choices 1 to 6;

[0119] Choose option 8, starting from the time slot corresponding to the last feedback perception information (the first symbol or the first time slot) until the end position determined by options 1 to 6;

[0120] Select 9, starting from the time slot corresponding to the last DCI that triggered the feedback sensing information (the first symbol or the first time slot) until the end position determined by selections 1 to 6.

[0121] By configuring the starting position of the measurement interval corresponding to the first downlink control information and the starting position of the measurement interval not corresponding to the first downlink control information in this embodiment, the flexibility of measurement result feedback can be improved while ensuring the integrity of the measurement result feedback.

[0122] In an exemplary embodiment, semi-continuous sensing information (stage measurement results) feedback and cross-time-slot sensing signals can be bound together. The feedback action of semi-continuous sensing information can be triggered by an event. That is, once the transmission of cross-time-slot sensing signals is triggered, the feedback of semi-continuous sensing information will be triggered until the termination of cross-time-slot sensing signals.

[0123] Correspondingly, the periodic, semi-continuous, or non-periodic feedback of the phased measurement results of the current sensing signal includes: periodically feeding back the phased measurement results of the current sensing signal on time-frequency domain resources associated with the current sensing signal.

[0124] Time-frequency domain resources refer to all available resources that can be allocated for information transmission in both the time and frequency dimensions. In this embodiment, the time-frequency domain resources associated with the current sensing signal refer to those available for transmitting interim measurement results in both the time and frequency dimensions. Interim measurement results are periodically fed back onto the time-frequency domain resources associated with the current sensing signal. Associating the sensing signal with the time-frequency domain resources allows the terminal device to anticipate the time points when interim measurement results need to be fed back, thereby pre-planning the preparation and feedback times for the interim measurement results, ensuring the continuity and integrity of the measurement, and achieving effective tracking of the sensing signal. Furthermore, the network side can adjust the time-frequency domain resources based on the periodically fed-back interim measurement results, improving the utilization efficiency of the time-frequency domain resources.

[0125] In this embodiment, the sensing signal and time-frequency domain resources are associated, and the phased measurement results are periodically fed back on the time-frequency domain resources associated with the sensing signal. For sensing signals transmitted across time slots, even if the signal spans multiple time slots, the continuity and integrity of the measurement can be ensured, and the sensing signal can be effectively tracked.

[0126] In an exemplary embodiment, during the periodic feedback of the phased measurement results of the sensed signal, if multiple terminal devices simultaneously feed back the phased measurement results to the network side or the same terminal device, it will not only cause signal conflicts, but also result in low resource utilization because the time-frequency domain resources are not pre-allocated according to the overall network transmission situation.

[0127] Therefore, in this embodiment, the association between the time-frequency domain resources of the phased measurement results of the sensing signal and the feedback sensing signal can be pre-configured. Correspondingly, before continuously measuring the current sensing signal starting from the transmission start symbol of the current sensing signal, the above method further includes: receiving resource configuration information, wherein the resource configuration information is used to configure the association between the time-frequency domain resources of the phased measurement results of the sensing signal and the feedback sensing signal; and receiving first control information, wherein the first control information is used to indicate or activate the transmission of the current sensing signal.

[0128] In this embodiment, resource configuration information can be sent from the network side to the terminal device via signaling. This resource configuration information can be used to specify the correlation between the time-frequency domain resources of the sensing signals sent to the terminal device and the phased measurement results of the feedback sensing signals. Furthermore, the resource configuration information can also characterize the temporal relationship between the sensing signals and the phased measurement results of the sensing signals, enabling the phased measurement results to continuously and orderly reflect the current measurement status. The resource configuration information can be pre-configured by the network side via higher-layer signaling.

[0129] The first control information can be used to indicate or activate the transmission of the current sensing signal. It can be high-level signaling sent from the network side to the terminal device, and may include, but is not limited to, RRC (Radio Resource Control), MAC-CE, DCI, etc. Upon receiving the first control information, the terminal device can know that the current sensing signal is about to be transmitted (which may correspond to a sensing mode where the network side or other terminal devices transmit and the current terminal device receives), or it can transmit the current sensing signal (which may correspond to a sensing mode where the terminal device transmits and receives signals independently).

[0130] For example, the network side can pre-configure the resources associated with the sensing reference signal for semi-persistent sensing information feedback via higher-layer signaling. Thus, when the network side instructs or activates the transmission of the sensing reference signal resources, it can automatically trigger or respond to the received feedback trigger information to provide sensing information feedback on the associated resources used for semi-persistent sensing information feedback.

[0131] In this embodiment, the resource configuration information informs the terminal device in advance of the correlation between the time and frequency resources to be used to send sensing signals and measurement results. Through precise configuration, resource waste can be avoided and timely data transmission can be ensured. By instructing or activating the transmission of sensing signals through the first control information, signal conflicts can be avoided caused by different network sides sending sensing signals to the terminal in the same time and frequency domain, thus reducing signal conflicts.

[0132] In one exemplary embodiment, there can be multiple triggering methods for the feedback of the phased measurement results of the current sensing signal, which can be selected according to the actual application requirements.

[0133] As an optional implementation, the phased measurement result of the current sensing signal is automatically triggered in response to the first control information. That is, a single control information can simultaneously instruct or activate the transmission of the sensing signal and trigger the feedback of the phased measurement result. This implementation reduces the interaction signaling between the network side and the terminal device, thus minimizing the consumption of network resources. Optionally, the terminal device can also trigger feedback of sensing information based on the sensing result. For example, during the transmission of the sensing signal, if the terminal device detects the appearance of a sensing target, a change in the number of sensing targets, or other sensing events through the received sensing signal, it can trigger feedback of sensing information for the current sensing signal. The feedback method can be periodic, semi-continuous, or non-periodic.

[0134] Alternatively, when the network side instructs the terminal to receive cross-timeslot sensing signals via DCI, MAC-CE, or RRC signaling, it can trigger the feedback of semi-persistent or aperiodic sensing information from the terminal device. The semi-persistent feedback resources (such as PUCCH or PUSCH) can be configured by the network side via RRC, and / or the semi-persistent feedback resources can be associated with the cross-timeslot sensing signals. This association can also be configured by the network side via RRC.

[0135] Alternatively, when the network side instructs the terminal to receive cross-timeslot sensing signals via DCI, MAC-CE, or RRC signaling, if the terminal device detects the presence of a sensing target, a change in the number of sensing targets, or other sensing events through the received sensing signals, it can trigger feedback of semi-persistent or non-periodic sensing information from the terminal device. The semi-persistent feedback resources (such as PUCCH or PUSCH) can be configured by the network side via RRC, and / or the semi-persistent feedback resources can be associated with the cross-timeslot sensing signals. This association can also be configured by the network side via RRC.

[0136] Alternatively, when the network side instructs the terminal to receive cross-timeslot sensing signals via DCI, MAC-CE, or RRC signaling, the DCI, MAC-CE, or RRC signaling may simultaneously indicate semi-persistent feedback resources (such as PUCCH or PUSCH) or non-periodic feedback resources (such as PUCCH or PUSCH) for feeding back sensing information. As another optional implementation, the phased measurement result of the current sensing signal is fed back in response to received feedback trigger information, wherein the feedback trigger information is used to trigger periodic feedback of the phased measurement result of the current sensing signal; that is, periodic feedback of the phased measurement result can be triggered by a separate feedback trigger information. The feedback trigger information and the first control information can be carried in the same instruction or in different instructions. Through the above implementation, the controllability of the feedback of phased measurement results can be improved, thereby adapting to different usage scenarios.

[0137] For example, during the transmission of the sensing reference signal across time slots, the network side can independently trigger the feedback of semi-continuous sensing information for the sensing reference signal.

[0138] In this embodiment, by automatically triggering the feedback of the phased measurement results through the first control information, the amount of control information that needs to be transmitted can be reduced, and the convenience of triggering the measurement result feedback can be improved; or, by triggering the feedback of the phased measurement results through separate feedback trigger information, unnecessary continuous measurement and feedback can be reduced, and the controllability of the phased measurement result feedback can be improved.

[0139] In an exemplary embodiment, during the transmission of the sensing signal, the terminal device needs to receive resource configuration information to associate the sensing signal with the phased measurement results, and also needs to receive control information or feedback trigger information to trigger periodic feedback. The timing of the two information receptions may be different. If the resource configuration information is received later, it may lead to processing errors due to the inability to find time-frequency domain resources. On the other hand, because the timing of the two information receptions is different, it is necessary to wait for the later information to be received before processing, which will increase the processing latency.

[0140] To reduce the number of interactions, control information carried in a command can be used to indicate or activate the transmission of the current sensing signal and indicate the time-frequency domain resources associated with the current sensing signal. Correspondingly, before continuously measuring the current sensing signal starting from the transmission start symbol of the current sensing signal, the method further includes: receiving second control information, wherein the second control information is used to indicate or activate the transmission of the current sensing signal and indicate the time-frequency domain resources associated with the current sensing signal, and the interim measurement results of the current sensing signal are automatically triggered in response to the second control information.

[0141] Here, the second control information can be used to indicate or activate the transmission of the sensing signal, and to indicate the time-frequency domain resources associated with the current sensing signal. In this case, both information indication purposes can be achieved through a single information reception. Here, the control information used to indicate or activate the transmission of the sensing signal and the configuration information used to indicate the time-frequency domain resources associated with the current sensing signal can be different; that is, the second control information can include control sub-information and configuration sub-information, both of which are carried in the same instruction.

[0142] The terminal device can receive the second control information and, based on the second control information, receive the current sensing signal and automatically trigger feedback of the phased measurement results of the current sensing signal. The second control information can be higher-layer signaling, which may include, but is not limited to, DCI, MAC-CE, etc. This embodiment does not impose any limitations on this.

[0143] For example, the network side can trigger the transmission of cross-timeslot sensing reference signals through DCI or MAC-CE, and can also carry indications of semi-persistent sensing information for the sensing reference signals in the DCI or MAC-CE, such as resources / timing (i.e., time-frequency domain resources).

[0144] In this embodiment, by activating the transmission of sensing signals, triggering the feedback of phased measurement results, and indicating the time-frequency domain resources associated with the sensing signals in a single information interaction, signaling overhead can be reduced, the utilization efficiency of wireless resources can be improved, and it is not necessary to wait for the reception of multiple independent control information before measuring and feeding back the sensing signals, thus reducing latency.

[0145] In an exemplary embodiment, for the case of periodically feeding back the phased measurement results of the current sensing signal, the feedback period of the phased measurement results can be either an equal time interval or a non-equal time interval. Feedback of phased measurement results at non-equal time intervals is not only inconvenient for planning but also prone to time-frequency domain resource conflicts. Therefore, in this embodiment, a scheme of feeding back phased measurement results at equal time intervals can be adopted. The equal or non-equal time intervals can be determined through a predefined method, configured by the network side via RRC, DCI, or MAC-CE, or related to the duration of the sensing signal.

[0146] Correspondingly, on the time-frequency domain resources associated with the current sensing signal, the phased measurement results of the current sensing signal are periodically fed back, including: on the time-frequency domain resources associated with the current sensing signal, the phased measurement results of the current sensing signal are fed back once at a specified time slot, wherein the phased measurement results of the current sensing signal fed back each time are measurement results that were measured before the time slot of the phased measurement results of the current sensing signal fed back each time and have not been fed back.

[0147] In this embodiment, the phased measurement results of the current sensing signal can be fed back once at specified time slots. The terminal device can feed back the phased measurement results on pre-allocated time-frequency domain resources according to predefined, fixed time slot intervals. The fed-back phased measurement results can be measurement results that have been measured up to the current time slot but have not been fed back by previous phased measurement results.

[0148] After receiving each interim measurement result, the receiver (e.g., the network side) can update the currently stored measurement results to ensure that the saved results are the latest feedback results. The sender of the current sensing signal (i.e., the receiver of the interim measurement results can be the same or different; if different, the sender and receiver can exchange information) can also adjust the transmission parameters of the current sensing signal based on the feedback interim measurement results. Through this method, the transmission accuracy of the current sensing signal can be continuously optimized and interference reduced in periodic feedback with equal time slots, thereby improving feedback quality.

[0149] For example, such as Figure 5As shown, for the received sensing signal, after the first feedback of the interim measurement result, an interim measurement result can be fed back every two time slots. The first feedback of the interim measurement result is the measurement result within the measurement range-4. The interim measurement result feedback performed by the UE is Semi-Persistent Channel State Information (SP-CSI) feedback.

[0150] In this embodiment, since each feedback is a previously measured result that has not been fed back, unnecessary repeated feedback is avoided, making the feedback process more efficient. At the same time, by feeding back the phased measurement results at specified time intervals, real-time monitoring and continuous tracking of the target can be achieved, improving the stability and reliability of the feedback.

[0151] In an exemplary embodiment, the final feedback of the stage measurement result of the sensing signal is based on the previously fed-out stage measurement results, and provides feedback on the remaining measurement information that has already been measured by the sensing signal. In different use cases, the measurement interval corresponding to the final feedback of the stage measurement result can be configured. Correspondingly, the time slot for the final feedback of the stage measurement result of the current sensing signal can be located within the time slot occupied by the current sensing signal. Here, limiting the final feedback to the time slot of the current sensing signal is equivalent to the current sensing signal and the final feedback being completed within the same time slot, which can reduce the latency of measurement information feedback; or, the time slot for the final feedback of the stage measurement result of the current sensing signal can exceed the last time slot occupied by the current sensing signal. Here, allowing the time slot of the final feedback to exceed the last time slot occupied by the current sensing signal (for example, the time slot of the final feedback may be the first time slot after the last time slot) allows for complete measurement of the sensing signal and also avoids interference to the sensing signal due to measurement result feedback, improving the integrity and reliability of the measurement result feedback.

[0152] For example, the last semi-persistent sensing information feedback can be limited to the time slot occupied by the sensing reference signal transmission, or it can be allowed that the last semi-persistent sensing information feedback can exceed the last time slot occupied by the sensing reference signal transmission.

[0153] In this embodiment, the time slot of the last feedback is limited. For sensing tasks with extremely low latency requirements, the time slot of the last feedback can be set within the time slot occupied by the current sensing signal to reduce latency. The time slot of the last feedback exceeds the last time slot occupied by the sensing signal, thus separating the transmission time slot and feedback time slot of the sensing signal to avoid interference from the feedback to the sensing signal being transmitted, thereby improving the quality and reliability of the feedback.

[0154] According to another aspect of the embodiments of this application, a method for measuring a sensed signal is also provided. Optionally, in this embodiment, the above-described method for measuring a sensed signal may be applied, but is not limited to, to applications such as... Figure 1 The hardware environment shown includes terminal device 102 and network-side device 104. This sensing signal measurement method can be applied to the network-side device and can be combined with the sensing signal measurement method provided in the above embodiments. Details already described will not be repeated here. Unless otherwise specified, the sensing signal measurement method in this embodiment can be arbitrarily combined with the sensing signal measurement method provided in the above embodiments.

[0155] Taking the measurement method of the sensed signal in this embodiment executed by the network-side device 104 as an example, Figure 6 This is a flowchart of another optional method for measuring a sensed signal according to an embodiment of this application, as shown below. Figure 6 As shown, the process of this method may include the following steps:

[0156] Step S602: Send the current sensing signal to the terminal device, wherein the current sensing signal is a sensing signal transmitted across time slots;

[0157] Step S604: During the current sensing signal transmission process, receive the phased measurement results of the current sensing signal from the terminal device, which are periodically, semi-continuously, or non-periodically fed back.

[0158] Optionally, the sensing signal measurement method in this embodiment can be applied to the communication field, specifically to detection and tracking service scenarios. The network-side device can send the current sensing signal to the terminal device and, during the transmission of the current sensing signal, receive periodic, semi-persistent, or non-periodic feedback of the phased measurement results of the current sensing signal from the terminal device. The current sensing signal, the method of sending the current sensing signal, and the method of feedback of the phased measurement results are the same as or similar to those in the previous embodiments, and have already been described, so they will not be repeated here.

[0159] The embodiments provided in this application send a current sensing signal to a terminal device, wherein the current sensing signal is a sensing signal transmitted across time slots; during the transmission of the current sensing signal, the terminal device periodically or semi-persistently or non-periodically receives the phased measurement results of the current sensing signal, thereby solving the technical problem of low speed resolution at the transmitting end of the sensing signal due to the limitation of the duration of the sensing signal in the measurement method of the sensing signal in the related art, and improving the speed resolution at the transmitting end of the sensing signal.

[0160] In one exemplary embodiment, before sending the current sensing signal to the terminal device, the method further includes: receiving capability indication information reported by the terminal device via higher-layer signaling (such as RRC), wherein the capability indication information is used to indicate that the terminal device has the capability to provide feedback on phased measurement results during the transmission of the sensing signal.

[0161] Through this embodiment, the capability indication information reported by the terminal device enables the network side to identify which terminal devices support cross-time slot signal measurement and feedback, thereby configuring corresponding sensing tasks for these terminal devices and ensuring that other terminal devices operate according to their capabilities. The network side can make more accurate resource allocation and control decisions based on the capabilities of the terminal devices, avoid unnecessary signal transmission and processing, and enhance the system's resource utilization efficiency and performance.

[0162] In an exemplary embodiment, the method further includes: during the current sensing signal transmission process, sending multiple downlink control messages to a terminal device, wherein each downlink control message is used to trigger the terminal device to feed back a phased measurement result of the current sensing signal.

[0163] This embodiment utilizes downlink control information to trigger feedback of each stage measurement result, allowing the network side to dynamically control the feedback cycle according to the needs of different services or the real-time status of the UE. This provides a finer control granularity, enabling the network side to dynamically adjust the feedback frequency as needed to meet the perception requirements in different scenarios.

[0164] In an exemplary embodiment, the interim measurement result of the current sensing signal is periodically fed back on time-frequency domain resources associated with the current sensing signal; before sending the current sensing signal to the terminal device, the method further includes one of the following: sending resource configuration information to the terminal device, wherein the resource configuration information is used to configure the association between the sensing signal and the time-frequency domain resources for feeding back the interim measurement result of the sensing signal; sending first control information to the terminal device, wherein the first control information is used to indicate or activate the transmission of the current sensing signal; sending second control information to the terminal device, wherein the second control information is used to indicate or activate the transmission of the current sensing signal and to indicate the time-frequency domain resources associated with the current sensing signal, and the interim measurement result of the current sensing signal is automatically triggered by the terminal device in response to the second control information.

[0165] In this embodiment, the association between time-frequency resources to be used for transmitting sensing signals and measurement results is communicated to the terminal device in advance through resource configuration information. Precise configuration avoids resource waste and ensures timely data transmission. Instructing or activating the transmission of sensing signals through first control information avoids signal conflicts caused by different network sides transmitting sensing signals to the terminal in the same time-frequency domain, reducing signal conflicts. Automatically triggering feedback of phased measurement results through first control information reduces the amount of control information that needs to be transmitted, improving the convenience of triggering measurement result feedback. Alternatively, triggering feedback of phased measurement results through separate feedback trigger information reduces unnecessary continuous measurement and feedback, improving the controllability of phased measurement result feedback. Utilizing second control information to simultaneously activate sensing signal transmission, trigger phased measurement result feedback, and indicate the associated time-frequency domain resources of the sensing signal through a single information interaction reduces signaling overhead, improves the utilization efficiency of wireless resources, and eliminates the need to wait for multiple independent control messages to be received before measuring and feeding back the sensing signal, thus reducing latency.

[0166] In one exemplary embodiment, the method further includes: stopping the transmission of the current sensing signal to the terminal device in response to a phased measurement result of the received current sensing signal.

[0167] For example, the network side can instruct the UE to provide feedback on the sensing information of the sensing signal and instruct the UE to stop transmitting the sensing signal via RRC signaling, MAC-CE signaling, or DCI signaling. Optionally, the sensing signal can terminate at the time slot where the RRC signaling, MAC-CE signaling, or DCI signaling is located, or stop at k time slots after or before the time slot where the RRC signaling, MAC-CE signaling, or DCI signaling is located. Here, k can be determined in a predetermined manner, or indicated by the network side via RRC signaling, MAC-CE signaling, or DCI signaling.

[0168] This embodiment allows for timely response to feedback of phased measurement results after receiving the current sensing signal's interim measurement results, avoiding resource waste and unnecessary interference with other data transmissions.
