Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a method and apparatus for configuring a reference signal. Background Technology

[0002] Essential components. The 3GPP standards organization initiated research into standards for intelligent radio access networks starting with Rel-16, and in Rel-18, it initiated a project on AI / ML-based 5G air interface enhancement, thus beginning international standardization work on the integration of 5G air interface and AI / ML. With the further deep integration of 5G-A / 6G mobile communication technologies and AI / ML technologies, more and more air interface functions will utilize AI / ML technologies to improve user experience and optimize network performance, resource management, and energy consumption.

[0003] In current discussions on 5G-A and 6G standards, utilizing AI for time-domain channel prediction is an important research direction. By analyzing historical channel state information, AI models can accurately predict channel changes over several time slots or even subframes in the future, theoretically significantly reducing the overhead of periodic measurement reference signals. For example, in beam management and CSI prediction scenarios, if a base station or terminal with AI capabilities can accurately predict the time-domain channel state, the measurement cycle of the SSB (Synchronization Block) or full-bandwidth CSI-RS (Channel State Information Reference Signal) can be increased, thereby reducing signal overhead and energy consumption during terminal measurement.

[0004] However, in actual network deployments, new terminals with AI capabilities and older terminals that only support traditional measurement methods inevitably coexist within the same cell. Currently, the configuration of common measurement signals (such as SSB and CSI-RS for beam management) is at the cell level, and their periodicity and density must be based on meeting the measurement needs of the weakest terminal. This means that even if base stations and some AI terminals have predictive capabilities, the overall overhead of common measurement signals in the network cannot be effectively reduced because the measurement needs of non-AI terminals must be considered. Figure 1 For example, the first line indicates that when only AI terminals exist in the network, the base station can configure a measurement reference signal with a longer period. The AI ​​terminal or the base station can then use AI to predict the channel state between two measurements, ensuring reliable communication transmission. The second line indicates that when only non-AI terminals exist in the network, the base station needs to configure a measurement reference signal with a shorter period to ensure that non-AI terminals can measure and report the channel state in a timely manner. The third line indicates that when both AI and non-AI terminals exist in the network, the base station also needs to configure a measurement reference signal with a shorter period to ensure the measurement needs of non-AI terminals. Therefore, from the base station's perspective, the introduction of AI functionality does not reduce the overhead of the network measurement reference signal.

[0005] Therefore, in 5G evolution or future 6G networks, when AI terminals and non-AI terminals coexist, base stations cannot effectively reduce the overall overhead of common measurement reference signals when configuring them at the cell or user group level because they must also consider the measurement needs of non-AI terminals. Furthermore, in existing standards, the configuration of measurement reference signals is transmitted via higher-layer RRC signaling, and the reset process can have a delay of tens of milliseconds. This configuration mode cannot adapt to scenarios with rapidly changing channels. If the base station configures measurement reference signals with a long period, it cannot dynamically and quickly obtain information about channel state changes of non-AI terminals.

[0006] Furthermore, in existing standards, the configuration of measurement reference signals is transmitted via higher-layer RRC signaling, and the reset process can have a delay of tens of milliseconds. This configuration mode cannot adapt to scenarios with rapidly changing channels. If the base station is configured with measurement reference signals of a longer period, it will be unable to dynamically and quickly obtain information about channel state changes of non-AI terminals. Summary of the Invention

[0007] This application proposes a method, device, and system for configuring reference signals, aiming to solve the technical problem that it is impossible to dynamically reduce the overhead of common measurement signals by utilizing the network-side AI prediction capabilities in networks where AI terminals and non-AI terminals coexist. It is particularly suitable for realizing intelligent channel measurement resource scheduling in 5G-Advanced and subsequent evolution communication systems.

[0008] In a first aspect, this application proposes a method for configuring a reference signal, applied to a wireless communication system. In this system, the network side is capable of performing channel state prediction, and at least one type of terminal device relies on a measurement reference signal configured by the network side to acquire the channel state. The method includes: configuring a main measurement reference signal and a dynamic trigger signal for the terminal device; wherein the time-domain configuration period of the main measurement reference signal is not less than the time-domain configuration period of the dynamic trigger signal; wherein the transmit power level of the dynamic trigger signal at its configured time-frequency resource location is used to transmit a dynamic indication to the terminal device: corresponding to a first power level, it is used to indicate that the terminal device should trigger the reception and measurement of the main measurement reference signal in the current scheduling time slot; corresponding to a second power level, it is used to indicate that the terminal device does not need to trigger the reception and measurement of the main measurement reference signal in the current scheduling time slot.

[0009] The method described in any embodiment of the first aspect of this application can also be used in a network-side device, which has channel state prediction capability and serves at least one type of terminal-side device that does not have the capability. The method includes: sending configuration signaling to the terminal-side device to configure a master measurement reference signal and a dynamic trigger signal, wherein the time-domain configuration period of the master measurement reference signal is not less than the time-domain configuration period of the dynamic trigger signal; dynamically deciding whether to trigger the terminal-side device to perform channel measurement in the current scheduling time slot based on the channel state prediction result of the terminal-side device; according to the result of the dynamic decision, sending a dynamic trigger signal with a corresponding power level at the time-frequency resource location of the dynamic trigger signal; and sending the master measurement reference signal at the time-frequency resource location of the master measurement reference signal corresponding to a first power level.

[0010] Furthermore, as described above, the dynamic decision-making based on the channel state prediction result includes: generating the dynamic trigger signal at a first power level in response to the predicted channel state information changing beyond the prediction confidence range; and / or generating the dynamic trigger signal at a second power level in response to the predicted channel state information changing within the prediction confidence range.

[0011] The method described in any embodiment of the first aspect of this application can also be used in a terminal-side device, wherein the terminal-side device does not have channel state prediction capability, and its channel state acquisition depends on a measurement reference signal configured by the network side. The method includes: receiving configuration signaling from the network-side device, acquiring configuration information of a main measurement reference signal and a dynamic trigger signal, wherein the time-domain configuration period of the main measurement reference signal is not less than the time-domain configuration period of the dynamic trigger signal; when only the dynamic trigger signal is configured in the current scheduling time slot, performing power detection on the time-frequency resource location of the dynamic trigger signal; if the detection result corresponds to a first power level, then triggering the reception and measurement of the main measurement reference signal.

[0012] In one embodiment of the first aspect, a measurement type is configured for the dynamic trigger signal, the measurement type including: a first state, instructing the terminal-side device to perform conventional reference signal measurement at the time-frequency resource location of the dynamic trigger signal; and a second state, instructing the terminal-side device to perform reference signal energy detection at the time-frequency resource location of the dynamic trigger signal; wherein, in order to trigger the reception and measurement of the main measurement reference signal, the measurement type of the dynamic trigger signal is configured to the second state.

[0013] In one embodiment of the first aspect, the number of subcarriers occupied by the main measurement reference signal in the frequency domain is greater than the number of subcarriers occupied by the dynamic trigger signal in the frequency domain.

[0014] In one embodiment of the first aspect, the time-domain configuration period of the dynamic trigger signal is set based on the minimum measurement requirements of the terminal device without relying on prediction.

[0015] In one embodiment of the first aspect, the time-domain configuration period of the master measurement reference signal is not less than or equal to the effective time window of the channel state prediction model of the network-side device.

[0016] Secondly, this application also proposes a network-side device for implementing the method described in any one of the first aspects of this application. At least one module in the network-side device is configured to perform at least one of the following functions: sending the configuration signaling to determine whether the terminal-side device needs to be triggered to perform channel measurement in the current scheduling time slot; sending a dynamic trigger signal with a corresponding power level at the time-frequency resource location of the dynamic trigger signal; and sending the main measurement reference signal at the time-frequency resource location of the main measurement reference signal corresponding to the first power level.

[0017] This application also proposes a terminal-side device for implementing the method described in any one of the first aspects of this application. At least one module in the terminal-side device is configured to perform at least one of the following functions: receiving the configuration signaling; performing power detection on the time-frequency resource location of the dynamic trigger signal when only the dynamic trigger signal is configured in the current scheduling time slot; determining the power level of the dynamic trigger signal; and receiving and measuring the main measurement reference signal.

[0018] This application also proposes a communication device, comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, implements the steps of the method as described in any embodiment of the first aspect of this application.

[0019] This application also proposes a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the method described in any embodiment of the first aspect of this application.

[0020] This application also proposes a wireless communication system, including at least one network-side device as described in any embodiment of this application, and at least one terminal-side device as described in any embodiment of this application.

[0021] The at least one technical solution adopted in this application embodiment can achieve the following beneficial effects: By configuring a main measurement reference signal and a dynamic trigger signal for the terminal-side device that relies on the measurement reference signal, and using the channel prediction capability of the network side to dynamically control the power level of the dynamic trigger signal to transmit indication, the network side can trigger the terminal-side device to perform high-overhead main measurement reference signal measurement only when necessary, thereby significantly reducing the measurement signal overhead of the overall system. Simultaneously, the period of the dynamic trigger signal is set based on the minimum measurement requirements of the terminal, and the period of the main measurement reference signal matches the prediction capability of the network side, ensuring that the system, while compatible with traditional terminals, can transform the intelligent prediction capability of the network side into actual network performance gains.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] The core technical concept of this application lies in proposing a "pre-configuration + dynamic triggering" signaling interaction mechanism to solve the problem of dynamically and efficiently managing the overhead of measurement reference signals in wireless communication systems where a network with channel prediction capabilities and a terminal device without such capabilities coexist. Specifically, the network side pre-configures a primary measurement reference signal with relatively high resource overhead for the terminal device via higher-layer signaling to define the complete channel measurement behavior. Simultaneously, the network side also configures a dynamic triggering signal with minimal resource overhead as a dynamic triggering command for the physical layer. Based on its channel state prediction results, the network side controls the transmit power level of this dynamic triggering signal on a specified time-frequency resource (e.g., distinguished by power values ​​above or below a certain threshold) to transmit a binary command of "execute measurement" or "skip measurement" to the terminal device in real time. The terminal device then interprets this command through simple power detection and determines accordingly whether to perform channel measurement at the pre-configured primary measurement reference signal resource location. This mechanism decouples the "content of measurement behavior" (statically defined by the main measurement reference signal) from the "scheduling of measurement behavior" (dynamically controlled by the dynamic trigger signal), thereby achieving millisecond-level fast and accurate control of the measurement behavior of terminal-side devices without the need for high-level signaling reconfiguration.

[0025] Based on the aforementioned core concepts, this application's specification adopts a hierarchical explanatory structure. First, it describes the complete process of the method from a system-wide perspective, introducing the core interaction mechanism. Second, it details the respective operation steps and decision-making logic from the execution perspectives of both the network-side device and the terminal-side device. Then, it deepens and refines the technical solution through specific examples, parameter relationships, and preferred implementation methods. Finally, it provides embodiments of devices for implementing the method, including network-side devices, terminal-side devices, communication devices, storage media, and communication systems. Each embodiment revolves around the aforementioned core concepts, collectively forming a complete technical solution system.

[0026] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0027] Figure 1This diagram illustrates the configuration overhead of measurement reference signals in existing technologies when AI terminals, non-AI terminals, and both coexist. The diagram clearly demonstrates the predicament of existing solutions in a hybrid terminal environment: when the network side possesses channel prediction capabilities and AI terminals are present, the configuration period for common measurement signals cannot be increased accordingly. Instead, a shorter period is still required to meet the measurement needs of non-AI terminals, preventing the realization of the potential benefits of AI capabilities.

[0028] Figure 2 This is a flowchart illustrating one embodiment of the method of this application. Figure 2 As shown, this application proposes a method for configuring a reference signal, applied to a wireless communication system comprising a network side and a terminal side. The network side is capable of performing channel state prediction, while at least one type of terminal-side device lacks channel state prediction capability, and its channel state acquisition depends on a measurement reference signal configured by the network side. The method includes the following steps 110-130: Step 110: Configure the main measurement reference signal and dynamic trigger signal for the terminal-side device.

[0029] In this step, "configuration" refers to informing the terminal-side device of the signal parameters via higher-layer signaling. In one embodiment, when a terminal without AI inference capabilities accesses the network, the base station configures the measurement reference signal to the non-AI terminal via RRC signaling.

[0030] The configuration of the measurement reference signal includes: a) The primary measurement reference signal, and the RRC signaling includes at least the resource type (e.g., the resourcetype field in TS38.331, RRCIE CSI-ResourceConfig), period and time-domain location (e.g., the periodicityAndOffset field in TS38.331, RRCIE NZP-CSI-RS-Resource), time-frequency resource location within the time slot (e.g., the CSI-RS-ResourceMapping field in TS38.331, RRCIE NZP-CSI-RS-Resource), and measurement type of the primary measurement reference signal.

[0031] b) A dynamic trigger signal, and the RRC signaling includes at least the resource type, period and time domain position of the dynamic trigger signal, the time-frequency resource location within the time slot, and the measurement type.

[0032] The time-domain configuration period of the primary measurement reference signal (hereinafter referred to as the first period) is not less than the time-domain configuration period of the dynamic trigger signal (hereinafter referred to as the second period); the number of frequency-domain subcarriers occupied by the primary measurement reference signal is not less than the number of frequency-domain subcarriers of the dynamic trigger signal (i.e., the primary measurement reference signal is sparser in the time domain and denser in the frequency domain; the dynamic trigger signal is denser in the time domain and sparser in the frequency domain). This defines the basic spatiotemporal resource characteristics of the two signals. The period of the primary measurement reference signal is not less than the period of the dynamic trigger signal; for example, the period of the primary measurement reference signal is 20ms, and the period of the dynamic trigger signal is 5ms. Figure 3 As shown.

[0033] The time-domain configuration period of the dynamic trigger signal can be set based on the minimum measurement requirements of the terminal device under conditions that do not rely on prediction. This means that the period of the dynamic trigger signal (e.g., 5ms) is aligned with the minimum measurement frequency required to ensure the basic performance of the non-AI terminal, ensuring that even in the worst case (when network-side prediction completely fails), the system can meet the terminal's needs through frequent command channels.

[0034] The time-domain configuration period of the primary measurement reference signal can be no less than or equal to the effective time window of the channel state prediction model of the network-side device. This means that the period of the primary measurement reference signal (e.g., 20ms) matches the AI ​​prediction capability of the network side, enabling the network side to confidently skip some measurement opportunities most of the time, thereby reducing overhead.

[0035] Step 120: Use the power level of the dynamic trigger signal to transmit a dynamic indication to the terminal.

[0036] The transmit power level of the dynamic trigger signal at its configured time-frequency resource location is used to transmit a dynamic indication to the terminal-side device.

[0037] Here, "transmit power level" is a physical layer parameter that can be controlled by the network side, and it is assigned specific signaling semantics. The dynamic indication is binary, specifically including: corresponding to the first power level, the transmit power level of the dynamic trigger signal is used to indicate that the terminal-side device should trigger the reception and measurement of the main measurement reference signal in the current scheduling time slot; corresponding to the second power level, the transmit power level of the dynamic trigger signal is used to indicate that the terminal-side device does not need to trigger the reception and measurement of the main measurement reference signal in the current scheduling time slot.

[0038] To ensure the terminal correctly interprets the indication conveyed by the power level, a specific "measurement type" needs to be configured for the dynamic trigger signal. This measurement type includes a first state and a second state. When configured in the first state, the terminal is instructed to perform a regular reference signal measurement at the time-frequency resource location of the dynamic trigger signal (in this case, the dynamic trigger signal serves as a second measurement reference signal with a period shorter than the main measurement reference signal, and can be used by non-AI terminals). When configured in the second state, the terminal is instructed to perform reference signal energy detection at the time-frequency resource location of the dynamic trigger signal (in this case, the dynamic trigger signal's power level is used to trigger the reception and measurement of the main measurement reference signal).

[0039] It is understandable that in this scheme, the base station is configured to use the second state (i.e., energy detection type) as the measurement type for the dynamic trigger signal. This allows the terminal to perform simple power detection instead of complex channel estimation at the time-frequency resource location of the signal, and to determine the network-side instructions based on whether the detected power is higher or lower than a preset threshold (i.e., the first power level or the second power level).

[0040] It is also understandable that when the base station is configured to use the measurement type of the dynamic trigger signal as the defined state, the terminal device will be decoupled from the function of "using the dynamic trigger signal at its power level as a trigger to receive and measure the main measurement reference signal" and will be converted to the regular measurement function of using the dynamic trigger signal as the measurement reference signal.

[0041] The function of the dynamic trigger signal lies in the binary information represented by its transmit power. For example, its power level is defined as a binary command: "First power level (high power) = Perform measurement (go to the master measurement reference signal position)", "Second power level (low / zero power) = Skip measurement". This signal acts as a physical layer signaling channel carrying 1 bit of control information, and its purpose is to dynamically indicate whether channel measurement needs to be performed using the master measurement reference signal in the current scheduling time slot. For example, the meaning of the first indication (corresponding to the first power level) can be: In the current scheduling time slot, the channel state has exceeded the prediction confidence range of the network-side equipment, and the terminal-side equipment needs to be triggered to perform channel measurement and feedback based on the master measurement reference signal; the meaning of the second indication (corresponding to the second power level) can be: In the current scheduling time slot, the channel state is within the prediction confidence range, and channel measurement does not need to be triggered. The terminal should process the remaining resources as data transmission.

[0042] Step 130: The terminal device performs the corresponding operation according to the dynamic instructions.

[0043] This step is the terminal's response to the dynamic indication conveyed in step 120. The terminal's operation depends on the indication corresponding to the power level of the detected dynamic trigger signal. Specific behavior will be described in detail in the subsequent embodiments from the terminal's perspective (steps 310-340).

[0044] Combining steps 110-130, the core interaction of this solution can be summarized as "pre-configuration + dynamic triggering." Its characteristics are: 1. Decoupling the content of the measurement behavior (defined by the main measurement reference signal) from the scheduling of the measurement behavior (controlled by the dynamic trigger signal); 2. Pre-configuring the content (all details of the main measurement reference signal) once and for all, storing it in the terminal's behavior instruction library; 3. Activating or suspending the corresponding measurement behavior from the instruction library by controlling a simple switch (the power of the dynamic trigger signal) in real time on the network side. This achieves microsecond / millisecond-level dynamic control capabilities while completely avoiding the overhead and latency of dynamically reconfiguring RRC signaling.

[0045] It should be noted that the above steps are used for network entities in a wireless communication system, including terminal-side devices, network-side devices, or other intermediate devices; the above steps can also be used for service devices that provide information processing for the network entity devices; the above steps can also be used for any device, system, subsystem, circuit, chip, or software entity that provides information reception, transmission, identification, and processing for terminal-side devices or network-side devices.

[0046] Figure 3 This is a schematic diagram illustrating the resource mapping between the primary measurement reference signal and the dynamic trigger signal in a specific example of this application. The shaded blocks in the first row of the diagram identify the primary measurement reference signal, whose configuration period is... The time-frequency resource mapping within a time slot is shown in the lower left of the figure. It occupies two OFDM symbols within a time slot, and in the frequency domain, it consists of all subcarriers within the entire Physical Resource Block (PRB). Blocks with different backgrounds represent different Codebook Groups (CDM groups), and different codebook groups correspond to different CSI-RS antenna ports. The second row of shaded blocks identifies the dynamic trigger signal, with a configuration period of 5ms. Its time-frequency resource mapping within a time slot is shown in the lower right of the figure. It occupies two OFDM symbols within a time slot, and in the frequency domain, it only occupies two subcarriers within the entire Physical Resource Block (PRB). This figure visually demonstrates that the main measurement reference signal occupies more subcarriers in the frequency domain than the dynamic trigger signal.

[0047] This design results in extremely low overhead for the dynamic trigger signal while ensuring the measurement accuracy of the main measurement reference signal. If existing measurement reference signal configurations are used, the actual overhead of the reference signal within 20ms is... According to the measurement reference signal configuration method proposed in this application, the actual overhead of the reference signal within 20ms is... (When both the first and dynamic trigger signals are configured in the same time slot, the base station will not send the dynamic trigger signal because the terminal will only perform measurements at the time-frequency resource location of the main measurement reference signal. Therefore, the actual reference signal overhead in this time slot only needs to be calculated based on the main measurement reference signal.) It can be seen that compared with existing measurement reference signal configuration methods, the overhead of the reference signal is significantly reduced.

[0048] Figure 4 This diagram illustrates the signal configuration within each time slot in a specific example of this application. The diagram clearly demonstrates how the method operates in actual time slots, including the behavior of the network side and the terminal side under different instructions. Specific embodiments will be described in conjunction with subsequent steps.

[0049] The following combination Figure 4 Through three typical time slot examples, the collaborative operation process between the network side and the terminal side is specifically illustrated: Time Slot 1: The current time slot is configured with both the primary measurement reference signal and the dynamic trigger signal. The base station only transmits the primary measurement reference signal at the time-frequency resource location corresponding to the primary measurement reference signal; at other time-frequency resource locations, it transmits control signaling, data information, DMRS, and other valid data symbols according to the existing configuration. The terminal performs routine reference signal measurements only at the time-frequency resource location of the primary measurement reference signal in the current time slot; at other time-frequency resource locations, it receives control signaling, data information, DMRS, and other valid data symbols according to the existing configuration.

[0050] Time Slot 2: The current time slot is only configured with a dynamic trigger signal. Based on its channel state prediction capability, the base station believes it can accurately predict the channel state information of the terminal within the current time slot using an AI model, and therefore decides not to trigger a measurement in the current time slot. The base station sets the transmit power to empty (i.e., transmits the second power level) at the time-frequency resource location corresponding to the dynamic trigger signal, and transmits control signaling, data information, DMRS, and other valid data symbols according to the existing configuration at the other time-frequency resource locations. The terminal performs power detection at the time-frequency resource location of the dynamic trigger signal in the current time slot. When the detected power level is lower than a preset threshold (i.e., corresponding to the second power level), the terminal determines that the base station has not instructed to perform channel measurement, and therefore receives control signaling, data information, DMRS, and other valid data symbols according to the existing configuration at the other time-frequency resource locations.

[0051] Time Slot 3: The current time slot is only configured with a dynamic trigger signal. Based on its channel state prediction capability, the base station believes that the AI ​​model can no longer accurately predict the channel state information of the terminal in the current time slot, and therefore decides to trigger a measurement in the current time slot. The base station allocates a certain power (i.e., transmits the first power level) at the time-frequency resource location corresponding to the dynamic trigger signal, and transmits the main measurement reference signal at the time-frequency resource location of the main measurement reference signal. At other time-frequency resource locations, control signaling, data information, DMRS and other valid data symbols are transmitted according to the existing configuration. The terminal performs power detection at the time-frequency resource location of the dynamic trigger signal in the current time slot. When the detected power level is higher than a preset threshold (i.e., corresponding to the first power level), the terminal determines that the base station has instructed it to perform channel measurement, and then performs a regular reference signal measurement at the time-frequency resource location of the main measurement reference signal, and receives control signaling, data information, DMRS and other valid data symbols at other time-frequency resource locations according to the existing configuration.

[0052] The above example demonstrates the dynamic collaboration process of this method, which involves "pre-configuration + dynamic triggering". The key to the effective and secure operation of the mechanism lies in the rational setting of the periods of the two signals: the time-domain configuration period of the dynamic trigger signal is set based on the minimum measurement requirements of the terminal-side device without relying on prediction; while the time-domain configuration period of the main measurement reference signal is not less than or equal to the effective time window of the channel state prediction model of the network-side device.

[0053] This means that the short period of the dynamic trigger signal (e.g., 5ms) aligns with the minimum measurement frequency required by traditional non-AI terminals to ensure basic performance. This setting ensures that even in the worst-case scenario (e.g., when drastic channel changes cause complete failure of network-side prediction), the network side can still safely degrade the system to the same short-period measurement mode as traditional solutions by sending a "measure" command (first power level) in every dynamic trigger signal cycle, thus ensuring uninterrupted communication links. During most of the time when the channel is stable and prediction confidence is high, the network side can confidently send a "no measurement" command (second power level), significantly reducing signal overhead by utilizing the long period of the main measurement reference signal (e.g., 20ms). This design allows the system to reliably and stably translate the network-side's intelligent prediction capabilities into actual network performance gains while remaining compatible with traditional terminals.

[0054] The specific implementation process of this method will be described below from the perspectives of the network side and the terminal side.

[0055] Figure 5 This is a flowchart illustrating an embodiment of the method of this application used in a network-side device. As shown, the method performed by the network-side device (e.g., a base station) includes the following steps 210-240: Step 210: Send configuration signaling to the terminal device to configure the main measurement reference signal and dynamic trigger signal.

[0056] This step corresponds to step 110 in the embodiment and is performed by the network side. The network-side device (such as a base station) sends RRC signaling to the terminal that lacks AI inference capabilities to configure a main measurement reference signal and a dynamic trigger signal. The configuration includes their respective resource types, periods, time-frequency locations, and measurement types, as described in step 110 above. The time-domain configuration period of the main measurement reference signal is configured to be no less than the time-domain configuration period of the dynamic trigger signal. For example, the period of the main measurement reference signal is configured to be 20ms, and the period of the dynamic trigger signal is configured to be 5ms. Figure 3 As shown.

[0057] Step 220: Based on the channel state prediction results of the terminal-side device, dynamically decide whether the terminal-side device needs to be triggered to perform channel measurement in the current scheduling time slot.

[0058] The network-side equipment possesses channel state prediction capabilities. It utilizes its AI / ML model to analyze historical channel information and predict future changes in channel state. Based on this prediction, the network dynamically decides whether non-AI terminals need to perform channel measurements in the current scheduling slot. Specifically, the dynamic decision-making based on the channel state prediction results includes: responding to the predicted change in channel state information exceeding the prediction confidence range, deciding to trigger measurement; and / or, responding to the predicted change in channel state information being within the prediction confidence range, deciding not to trigger measurement. This is the core of the entire scheme's intelligent dynamic scheduling, enabling the network to confidently skip measurements when the channel is stable and promptly trigger measurements when the channel may undergo drastic changes.

[0059] The logic for dynamic decision-making based on channel state prediction results can be specifically described as follows: In response to the predicted channel state information changing beyond the prediction confidence range, a decision is made to trigger measurement, and a dynamic trigger signal at a first power level is generated; and / or, in response to the predicted change being within the prediction confidence range, a decision is made not to trigger measurement, and a dynamic trigger signal at a second power level is generated. The only reasonable basis for the network side to decide to send a "measure" or "do not measure" instruction (reflected by the power of the dynamic trigger signal) is the prediction result and confidence level of the future channel state. This transforms the "second instruction (do not measure)" from a risky operation that may impair performance into a technically guaranteed optimized operation.

[0060] The time-domain configuration period of the primary measurement reference signal can be no less than or equal to the effective time window of the channel state prediction model of the network-side device. This means that the period of the primary measurement reference signal (e.g., 20ms) matches the AI ​​prediction capability of the network side, enabling the network side to confidently skip some measurement opportunities most of the time, thereby reducing overhead.

[0061] Step 230: Based on the results of the dynamic decision, send a dynamic trigger signal with the corresponding power level at the time-frequency resource location of the dynamic trigger signal.

[0062] Based on the decision in step 220, the network side controls the transmission power of the dynamic trigger signal. If the decision indicates that a measurement needs to be triggered, a signal at a first power level (e.g., high power) is transmitted at the time-frequency resource location of the dynamic trigger signal; if the decision indicates that a measurement does not need to be triggered, a signal at a second power level (e.g., low power or zero power) is transmitted. For example, in time slot 2 (e.g., Figure 4 The base station believes that it can accurately predict the channel state information of the terminal in the current time slot using the AI ​​model, and therefore does not need to configure a measurement reference signal in the current time slot. Therefore, it sets the power to empty (i.e., transmits the second power level) at the time-frequency resource location corresponding to the dynamic trigger signal, and transmits control signaling, data information, DMRS, and other valid data symbols at the remaining time-frequency resource locations according to the existing configuration. In time slot 3 (e.g....) Figure 4 The base station believes that the AI ​​model can no longer accurately predict the channel state information of the terminal in the current time slot, and therefore needs to configure a measurement reference signal in the current time slot. Thus, a certain amount of power (i.e., transmitting the first power level) is allocated to the time-frequency resource location corresponding to the dynamic trigger signal.

[0063] Step 240: Corresponding to the first power level, transmit the main measurement reference signal at the time-frequency resource location of the main measurement reference signal.

[0064] This step is related to the action of sending the first power level dynamic trigger signal in step 230. When the network side decides that a measurement needs to be triggered and therefore sends the first power level dynamic trigger signal, it simultaneously sends the main measurement reference signal at the time-frequency resource location of the main measurement reference signal. For example, in time slot 3 (e.g. Figure 4 The base station transmits the main measurement reference signal at the time-frequency resource location of the main measurement reference signal while simultaneously transmitting the first power level dynamic trigger signal. In time slot 1 (e.g., Figure 4The current time slot is equipped with both a primary measurement reference signal and a dynamic trigger signal. The base station only transmits the primary measurement reference signal at the time-frequency resource location corresponding to the primary measurement reference signal. At other time-frequency resource locations, control signaling, data information, DMRS, and other valid data symbols are transmitted according to the existing configuration. This indicates that when the network side decides to trigger a measurement, the transmission of the primary measurement reference signal actually occurs, providing the terminal with a measurable signal.

[0065] Figure 6 This is a flowchart illustrating an embodiment of the method of this application used in a terminal-side device. As shown in the figure, the method executed by the terminal-side device (non-AI terminal) includes the following steps 310-340: Step 310: Receive configuration signaling from the network-side device and obtain configuration information for the main measurement reference signal and dynamic trigger signal.

[0066] The terminal device receives RRC signaling from the network side to obtain complete configuration information of the main measurement reference signal and the dynamic trigger signal, including the period, time-frequency location, and measurement type, as described in step 110 above. Based on this, the terminal knows which time slots to listen to the dynamic trigger signal and the resource locations where the main measurement reference signal may appear.

[0067] Step 320: When the current scheduling time slot is only configured with the dynamic trigger signal, perform power detection on the time-frequency resource location of the dynamic trigger signal.

[0068] The terminal determines the signal configuration of the current time slot based on the configuration information. If the current time slot is only configured with a dynamic trigger signal (i.e., not a planned transmission time slot for the main measurement reference signal), the terminal performs this step. Because the measurement type of the dynamic trigger signal is configured as the second state (energy detection) by the network side, the terminal performs power detection at the time-frequency resource location of this signal, rather than a conventional reference signal measurement. For example, in time slot 2 (e.g.... Figure 4 The terminal performs power detection on the time-frequency resource location of the dynamic trigger signal in the current time slot.

[0069] Step 330: Determine the detected power level.

[0070] The terminal compares the power value detected in step 320 with a preset threshold. If the detected power level is higher than the threshold, the preset condition is considered to be met (corresponding to the first power level); if the detected power level is lower than the threshold, the preset condition is considered not met (corresponding to the second power level).

[0071] Step 340: If the detection result corresponds to the first power level, then trigger the reception and measurement of the main measurement reference signal.

[0072] This step is the final execution of the network-side instructions by the terminal. If step 330 determines that a first power level has been detected, the terminal assumes that the base station has transmitted a measurement reference signal in the current time slot, and then performs a routine reference signal measurement at the time-frequency resource location of the main measurement reference signal. For example, in time slot 3 (e.g., Figure 4 If the terminal detects that the power of the dynamic trigger signal is higher than the threshold, it knows that the base station has sent a measurement reference signal in the current time slot. Then, it performs a regular reference signal measurement at the time-frequency resource location of the main measurement reference signal, and receives control signaling, data information, DMRS and other valid data symbols at the other time-frequency resource locations according to the existing configuration.

[0073] If step 330 determines that a second power level has been detected, the terminal assumes that the base station has not instructed dechannel measurement, and that all other time-frequency resource locations in the current time slot are transmitting data symbols. The terminal then receives signals from other resource locations according to the normal data transmission procedure. For example, in time slot 2 (e.g., Figure 4 If the terminal detects that the power level of the dynamic trigger signal is lower than the threshold, it knows that the base station has not sent a measurement reference signal in the current time slot, and receives control signaling, data information, DMRS and other valid data symbols in the other time and frequency resource locations according to the existing configuration.

[0074] The time-domain configuration period of the dynamic trigger signal can be set based on the minimum measurement requirements of the terminal-side device under conditions that do not rely on prediction. The time-domain configuration period of the main measurement reference signal can be no less than or equal to the effective time window of the channel state prediction model of the network-side device.

[0075] It should be noted that this solution possesses an inherent robust degradation mechanism. In the worst-case scenario (such as extremely unstable channels, completely exceeding the AI's prediction capabilities), the network side, due to its uncertainty in each prediction, will send a "measurement" command (first power level) in every dynamic trigger signal time slot. At this point, the terminal will trigger a measurement of the main measurement reference signal every dynamic trigger signal cycle (e.g., every 5ms). This completely degrades to the short-cycle measurement mode configured in traditional solutions to meet the needs of non-AI terminals, thus ensuring no performance degradation. This demonstrates that this solution can significantly reduce overhead in the best-case scenario and safely degrade to a traditional solution in the worst-case scenario, possessing the robustness required for engineering applications.

[0076] Figure 7 This is a schematic diagram of an embodiment of a network-side device.

[0077] This application provides a network-side device for implementing the method of any embodiment of this application. The network-side device is configured to: send configuration signaling to a terminal-side device to configure a master measurement reference signal and a dynamic trigger signal for it; dynamically decide whether to trigger the terminal-side device to perform channel measurement in the current scheduling time slot based on the channel state prediction result of the terminal-side device; according to the result of the dynamic decision, send a dynamic trigger signal with a corresponding power level at the time-frequency resource location of the dynamic trigger signal; and when the decision is that measurement needs to be triggered, send the master measurement reference signal at the time-frequency resource location of the master measurement reference signal.

[0078] To implement the above technical solution, this application proposes a network-side device 400, which includes a network transmitting module 401, a network determining module 402, and a network receiving module 403 that are interconnected.

[0079] The network transmission module 401 is used to perform the functions of sending RRC configuration signaling to the terminal-side device, as well as sending dynamic trigger signals and main measurement reference signals. Specifically, when a terminal accesses the network, the network transmission module 401 configures the main measurement reference signal and dynamic trigger signal to the terminal without AI inference capabilities via RRC signaling. The configuration signaling includes at least the resource type, period, and time-domain location of the main measurement reference signal, the time-frequency resource location within the time slot, the measurement type, and the corresponding configuration information of the dynamic trigger signal. In subsequent communication, the network transmission module 401, based on the decision of the network determination module 402, sends a dynamic trigger signal with a first power level or a second power level at the time-frequency resource location of the dynamic trigger signal. When the decision requires triggering a measurement, the network transmission module 401 is also responsible for sending the main measurement reference signal at the time-frequency resource location of the main measurement reference signal. For example, in Figure 4 In time slot 3 shown, network transmission module 401 transmits high power on the dynamic trigger signal resource and transmits the signal on the main measurement reference signal resource.

[0080] The network determination module 402 is used to perform dynamic decision-making based on channel state prediction results. This module can utilize AI / ML models built into network-side devices or externally to analyze historical channel state information and predict future channel changes. Its decision logic is specifically as follows: In response to the predicted channel state information change exceeding the prediction confidence range, a decision is made to trigger measurement, and the network transmission module 401 is instructed to generate a dynamic trigger signal for a first power level; and / or, in response to the predicted channel state information change being within the prediction confidence range, a decision is made not to trigger measurement, and the network transmission module 401 is instructed to generate a dynamic trigger signal for a second power level. For example, in... Figure 4In time slot 2, the network determination module 402 determines that the channel state is within the predicted confidence range, therefore decides not to trigger the measurement, and instructs to send a dynamic trigger signal for the second power level.

[0081] The network receiving module 403 is used to receive uplink signals, measurement feedback (such as CSI reports), or other control information from the terminal-side device. The prediction and decision-making process of the network determination module 402 may also use historical data received by the network receiving module 403 as input.

[0082] The specific methods for implementing the functions of the network sending module 401, the network determining module 402, and the network receiving module 403 are as described in the various method embodiments of this application, and will not be repeated here.

[0083] The specific methods for implementing the functions of the network sending module, network determining module, and network receiving module are as described in the various method embodiments of this application, and will not be repeated here.

[0084] The network-side equipment described in this application may refer to base station facilities, network-side equipment or servers connected to base stations, systems that provide services for the aforementioned equipment, or any system, subsystem, module, circuit, chip or software operating device that provides information reception, transmission, identification and processing for the aforementioned equipment.

[0085] Figure 8 This is a schematic diagram of an embodiment of the terminal-side device.

[0086] This application also proposes a terminal-side device for implementing the method of any embodiment of this application. The terminal-side device is configured to: receive configuration signaling from a network-side device to obtain configuration information of a main measurement reference signal and a dynamic trigger signal; when only the dynamic trigger signal is configured in the current scheduling time slot, perform power detection on the time-frequency resource location of the dynamic trigger signal; and, based on the power detection result, if it corresponds to a first power level, trigger the reception and measurement of the main measurement reference signal.

[0087] To implement the above technical solution, this application proposes a terminal-side device 500, which includes a terminal transmitting module 501, a terminal determining module 502, and a terminal receiving module 503 that are interconnected.

[0088] The terminal receiving module 503 is used to receive configuration signaling, dynamic triggering signals, and main measurement reference signals from network-side devices. Specifically, during the connection establishment phase, the terminal receiving module 503 receives configuration information sent by the network side via RRC signaling, and learns the period, time-frequency location, and measurement type of the main measurement reference signal and dynamic triggering signal. During communication, the terminal receiving module 503 receives signals at the time-frequency resource locations specified by the configuration information.

[0089] The terminal determination module 502 is used to perform power detection and judgment functions for the dynamic trigger signal. According to the configuration, the measurement type of the dynamic trigger signal is configured as the second state (energy detection). Therefore, the terminal determination module 502 performs power detection on the time-frequency resource location of the signal in the time slot configured with the dynamic trigger signal (especially in the time slot only configured with this signal). The specific detection process includes measuring the power value of the received signal and comparing it with a preset threshold to determine whether the received signal is at a first power level or a second power level. For example, if the detected power value is higher than the preset threshold, it is determined to be at the first power level; if it is lower than or equal to the preset threshold, it is determined to be at the second power level.

[0090] The terminal sending module 501 is used to send uplink data, control information, or channel status feedback (such as a CSI report) to the network-side device. For example, after the terminal determination module 502 triggers the measurement of the main measurement reference signal, a CSI report may be generated based on the measurement results and sent to the network side through the terminal sending module 501.
