Abstract

The application provides a communication method, device, system and storage medium. The method can be applied to validity management of an association identifier. In the method, a terminal device receives first signaling sent by a network device, the first signaling including a first identifier and a first validity duration. The first identifier is used to indicate a resource allocated to the terminal device by the network device, and the first validity duration is determined by the network device based on a mobility level of the terminal device and a stability level of a beam. The method can manage the validity of the first identifier based on the first validity duration, avoid the problem of resource waste caused by the terminal device not releasing the resource in time after the first identifier becomes invalid, and also avoid the problem of reduced communication reliability caused by the terminal device using the resource corresponding to the invalid first identifier.

Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method, apparatus, system and storage medium. Background Technology

[0002] The 3rd Generation Partnership Project (3GPP), in Release 19 and subsequent 6G evolution, is actively promoting the application of artificial intelligence (AI) and machine learning (ML) on the radio access network (RAN) side to optimize beam management, mobility management, channel state information (CSI) feedback, and network energy saving. To ensure the effectiveness of AI / ML models, a core prerequisite is that the AI / ML models on the user equipment (UE) side have the same or consistent "network assumptions" as those on the network side (e.g., gNB) during the training and inference phases.

[0003] To achieve this goal, Release 19 introduced the associated identifier (Associated ID). The core objective of this associated identifier is to serve as a unique identifier for a specific set of "network-side additional conditions" (such as antenna configuration, beam deployment scheme, codebook resources, etc.). In other words, the network configuration associated with this identifier is consistent and valid within a specific scope (such as one or more cells). This associated identifier ensures that the UE's AI / ML model has the same network assumptions during the training and inference phases, thereby guaranteeing the model's accuracy and stability.

[0004] Currently, the lack of a dynamic management mechanism for the lifecycle of associated identifiers leads to resource waste and decreased communication reliability due to the failure of associated identifiers. Summary of the Invention

[0005] This application provides a communication method, apparatus, system, and storage medium that can avoid resource waste and communication reliability degradation caused by the failure of associated identifiers.

[0006] Firstly, a communication method is provided. This method can be executed by a terminal device, or by a component (such as a circuit, chip, or chip system) configured in the terminal device, or by a logic module or software capable of implementing all or part of the functions of the terminal device. This application does not limit this approach. The following description uses a terminal device as an example.

[0007] The method includes: a terminal device receiving a first signaling message sent by a network device, the first signaling message including a first identifier and a first validity period. The first identifier is used to indicate resource configuration on the network device side, and the first validity period indicates the validity duration of the first identifier. The first validity period is determined by the network device based on the terminal device's mobility level and beam stability level. The terminal device manages the validity of the first identifier based on the first validity period to avoid resource waste caused by the terminal device failing to release resources in a timely manner after the first identifier expires, and also to avoid communication reliability degradation caused by the terminal device using resources corresponding to the expired first identifier.

[0008] Secondly, a communication method is provided, which can be executed by a network device, or by a component (such as a circuit, chip, or chip system) configured in the network device, or by a logic module or software capable of implementing all or part of the functions of the network device.

[0046] To facilitate understanding of the embodiments of this application, the terminology used in this application will be briefly explained first. Optionally, the explanation of some terms can also be found in the 3GPP standard protocol.

[0047] 1. Association Identifier (Association ID)

[0048] In the evolution of 5G standards, the association ID mechanism introduced in Release 19 is mainly used to identify and manage a specific set of network-side configuration parameters. The core objective of this mechanism is to establish a precise mapping between network resources and user equipment, thereby improving the efficiency and flexibility of radio resource scheduling. The network-side additional conditions associated with the association ID mainly include antenna configuration parameters, beam deployment schemes, and codebook resource configurations. Through this association mechanism, 5G networks can more flexibly adapt to the service needs of different deployment scenarios, including the diverse characteristics of mobile internet and IoT services.

[0049] 2. Cell handover (or cell reselection)

[0050] In mobile communication and network technologies, especially in cellular networks (such as 3G, 4G, and 5G), cell handover refers to the process by which a mobile device switches from one base station to another to maintain communication continuity. Cell change frequency refers to the number of times a mobile device performs cell handover within a given time period. In practical applications, mobile devices can track their own cell handover frequency over a given period.

[0051] 3. Mobility State

[0052] In 5G networks, speed state, also known as mobility state, reflects the mobility status of the UE, including parameters such as speed and direction. It can be used to assist the network in making cell reselection and handover decisions. 3GPP defines three types of speed states: High Mobility state, Medium Mobility state, and Normal Mobility state.

[0053] The mobility state can be determined by the number of cell reselections within a certain time period. Specifically, if the number of cell reselections within time period T is less than N1, the mobility state is Normal Mobility state; if the number of cell reselections within time period T is greater than or equal to N1 and less than or equal to N2, the mobility state is Medium Mobility state; if the number of reselections within time period T is greater than N2, the mobility state is High Mobility state.

[0054] It should be understood that the technical terms used in this application are for illustrative purposes only and not as limiting. For example, as technology evolves, technical terms may also change, and other technical terms that have the same technical meaning should also apply to this application.

[0055] Currently, the specific design and scope of application of associated IDs have sparked controversy in the industry, with the existing debate mainly revolving around two major technical challenges:

[0056] Challenge 1: Should the association ID be "cell-specific" or "multi-cell-specific"? To support network deployment flexibility (e.g., an association ID can be used for a specific beam deployment in a single cell or for a similar beam deployment shared by multiple cells), the association ID is defined as a 24-bit field and is unique within a public land mobile network (PLMN).

[0057] Challenge 2: Lack of a management mechanism for the dynamic evolution of network configuration. Specifically, the UE cannot proactively determine whether the associated ID has expired (e.g., after network hardware replacement, the beam deployment corresponding to the original associated ID no longer exists), resulting in the long-term occupation of resources corresponding to the original associated ID. Even if the UE receives a new associated ID from the network device, the UE needs to manually release the resources corresponding to the original associated ID, which is inefficient and prone to omissions. These resources can be AI / ML models, and / or the computing resources, memory resources, etc., occupied by the AI / ML model.

[0058] This indicates a critical "management vacuum": while associated IDs are defined, a management mechanism for their lifecycle is lacking. Associated IDs possess a degree of staticity and correspond to fixed network beam characteristics within their consistent coverage area, but this "static correspondence" cannot be assumed to be permanently valid. Network-side beam deployment may change due to hardware replacements, software upgrades, or physical changes in the channel environment (such as new building obstructions). When network-side beam deployment changes, the physical characteristics corresponding to the original associated ID no longer exist. The network should be able to indicate to the UE that a particular associated ID is no longer valid, allowing the UE to release or retrain its corresponding AI / ML model.

[0059] This static and rigid management mechanism can lead to serious functional mismatch in two key scenarios:

[0060] Scenario 1: Waste of resources on the UE side and difficulties in network evolution

[0061] The UE continuously maintains and runs AI / ML models based on invalid association IDs, resulting in a significant waste of UE computing and memory resources. Conversely, this also hinders the flexible evolution of the gNB, because the gNB cannot securely "recall" or "cancel" an outdated association ID without affecting existing UEs.

[0062] Scenario 2: Decision-making mismatch in the handover (HO) scenario (key issue)

[0063] When a UE moves and performs a cell handover, the validity of the associated ID it carries becomes extremely uncertain:

[0064] Scenario 1 (Association ID Mismatch): The UE switches to the target cell (Target gNB), which does not support the association ID of the source cell (Source gNB). The UE must immediately discard all related models, causing the gains brought by AI / ML to be instantly reduced to zero. The AI / ML function needs to be retrained, resulting in performance jitter.

[0065] Scenario 2 (False Matching of Associated IDs): The target cell may use a different associated ID, or (due to the 24-bit global uniqueness) use the same associated ID, but the physical beam characteristics corresponding to that associated ID in the target cell are different from those in the source cell. Due to the lack of a clear validity management mechanism, the UE cannot make the correct decision and may incorrectly reuse the model based on the source cell assumption, leading to a sharp deterioration in communication performance after handover.

[0066] To address the issues of static, rigid, and unadaptable association ID validity management mechanisms in traditional technologies (i.e., when receiving a new association ID, the UE needs to manually release the old model, which is inefficient and prone to loss), and to solve the problem of optimizing the decision on the compatibility of association IDs with the model during cell handover, so as to avoid resource waste and communication reliability degradation caused by improper association ID invalidation strategies.

[0067] In view of this, this application provides a communication method in which a network device determines the validity period of an associated ID based on the mobility level and beam stability level of the terminal device, and simultaneously sends the associated ID and the validity period to the terminal device. In this way, the terminal device can accurately manage the validity of the associated ID based on the validity period, avoiding resource waste and communication reliability degradation caused by the invalidation of the associated ID.

[0068] The validity duration can be carried through the validity policy indicator (VPI). The VPI is used to standardize the validity policy selected by the network device for the associated ID, ensuring that the UE can accurately parse and execute it.

[0069] The solution provided in this application will be described in detail below with reference to the corresponding flowcharts. It is understood that the illustrative flowcharts provided in this application primarily use different devices (e.g., terminal devices, network devices) as examples of the execution subjects of this interactive illustration to illustrate the method, but this application does not limit the execution subjects of the interactive illustrations. For example, the devices (e.g., terminal devices, network devices) in the illustrative flowcharts can also be chips, chip systems, or processors that support the implementation of this method on the device, or logic modules or software that can implement all or part of the functions of the device.

[0070] As a general statement, the message or signaling interactions involved in the interaction process of this application embodiment can be standard messages or signaling or newly introduced messages or signaling. This application embodiment does not make specific limitations on this.

[0071] Figure 2 This is a schematic diagram of a communication method according to an embodiment of this application. It can be understood that... Figure 2 The terminal device in the middle can be Figure 1 Any terminal device in the context of network equipment can refer to any component within that terminal device (such as a processor, chip, or chip system). Network equipment can be... Figure 1 Any access network device, or a component within an access network device (such as a processor, chip, or chip system). Figure 2 As shown, the method includes the following steps:

[0072] S201: The network device obtains the stability level of the beam on the terminal device side and the mobility level of the terminal device.

[0073] Here, beam refers to the beam used by the terminal device during communication. Specifically, it refers to the uplink beam used by the terminal device to send data to the network device. Beam stability refers to the ability of the beam to maintain its direction, intensity, and shape during propagation. Terminal device mobility reflects the speed of terminal device movement and / or the frequency of cell handover. Mobility level is used to reflect the adaptation requirements between the dynamic behavior characteristics of the UE and the network resource configuration.

[0074] In this application, the network device can determine the validity period of the association ID based on the beam stability level (BSL) and the UE mobility level (UML). The association ID indicates the resource configuration on the network device side, which may include a set of resources allocated by the network device to the terminal device. For details on the generation of the association ID, please refer to existing methods; these will not be elaborated upon in this embodiment. The association ID is the first identifier described below.

[0075] The methods by which network devices obtain the mobility level and beam stability level of terminal devices may include:

[0076] (a) Initial state

[0077] Before the terminal device sends signaling to the network device, determine whether the terminal device has a cell handover history:

[0078] If a terminal device has no cell handover history, the network device directly assigns the corresponding mobility level to level three, i.e., UML3. Similarly, the network device assigns the beam stability level to level two, i.e., BSL2. For example, when a terminal device hands over from idle to connected mode, it has no cell handover history.

[0079] If the terminal device has a cell handover history, the target network device (i.e., the network device the UE is currently accessing) uses the context information about the terminal device sent by the source network device to determine the terminal device's mobility level and beam stability level. That is, the UE's context information transmitted by the source network device is used as the basis for determining the mobility and stability levels. This context information may include the cell handover frequency, rate status, and channel state measurement reports reported by the UE, among other things.

[0080] (ii) Dynamic adaptation status

[0081] Once signaling interaction begins between the terminal device and the network device, the terminal device can report its mobility level to the network device. Specifically, the terminal device obtains its current mobility level and sends a second signaling message to the network device. Correspondingly, the network device receives the second signaling message, which includes the current mobility level. This second signaling message can be radio resource control (RRC) signaling.

[0082] In some implementations, the terminal device obtains its current mobility level by acquiring the cell handover frequency or rate status corresponding to itself at the current moment, and determining its current mobility level based on that cell handover frequency or rate status. That is, the terminal device can determine its current mobility level based on its internal statistical parameters.

[0083] Specifically, if the cell handover frequency is greater than the first handover threshold or the rate state is in the first state, the terminal device determines its current mobility level as the first level. For example, if the first handover threshold is N times / minute, and cellChangeFrequency > N times / minute, or MobilityState = High, then the terminal device's mobility level is UML1 (high mobility).

[0084] If the cell handover frequency is less than or equal to the first handover threshold and greater than the second handover threshold, or the rate state is the second state, the terminal device determines that the mobility level at the current moment is the second level. Among them, the mobility indicated by the first level is higher than the mobility indicated by the second level. For example, the second handover threshold is M (M < N). If cellChangeFrequency is between M and N, or MobilityState = Medium, the mobility level of the terminal device is UML2 (medium mobility).

[0085] If the cell handover frequency is less than the second handover threshold or the rate state is the third state, the terminal device determines that the mobility level at the current moment is the third level, and the mobility indicated by the second level is higher than the mobility indicated by the third level. For example, cellChangeFrequency < M, or MobilityState = Normal or Stationary (stationary state), the mobility level of the terminal device is UML3 (low mobility or stationary).

[0086] Among them, the network device obtains the stability level of the UE-side beam, including: the network device obtains the channel state measurement report corresponding to the terminal device and determines the stability level of the beam based on the channel state measurement report. Among them, the channel state measurement report mainly includes key parameters such as channel quality indicator, precoding matrix indicator, transmission layer indicator, rank indicator, reference signal received power (RSRP), and reference signal received quality (RSRQ), which are used for the base station to optimize scheduling and beamforming. That is, the network device determines the stability level of the beam according to the relevant parameters in the channel state measurement report.

[0087] Furthermore, the network device can determine the stability level of the beam based on the RSRQ and RSRP reported by the terminal device. Specifically, it includes:

[0088] If the RSRP is greater than the first power threshold and the RSRQ is greater than the first quality threshold, the network device determines that the stability level of the beam is the first level.

[0089] If the RSRP is less than or equal to the first power threshold and greater than or equal to the second power threshold, and / or the RSRQ is less than or equal to the first quality threshold and greater than or equal to the second quality threshold, the network device determines that the stability level of the beam is the second level. Among them, the second power threshold is less than the first power threshold.

[0090] If RSRP is less than the second power threshold and / or RSRQ is less than the second quality threshold, the network device determines the beam stability level to be level three.

[0091] Among them, the stability corresponding to the first level is higher than that corresponding to the second level, and the stability corresponding to the second level is higher than that corresponding to the third level.

[0092] For example, as shown in Table 1, the first power threshold is X1dBm, the second power threshold is X2dBm, the first quality threshold is Y1dBm, and the second quality threshold is Y2dBm.

[0093]

[0094] S202: Network devices determine the first effective duration based on stability and mobility levels.

[0095] In this embodiment, the network device dynamically determines the first effective duration of the associated ID based on UML and BSL. Specifically, this may include: the network device determining a first compensation coefficient based on the mobility level of the terminal device, and determining a second compensation coefficient based on the beam stability level, and determining the first effective duration based on the reference duration, the first compensation coefficient, and the second compensation coefficient.

[0096] The first compensation coefficient is negatively correlated with the mobility level; that is, the higher the mobility, the smaller the first compensation coefficient, thus shortening the validity period of the associated ID. For example, the first compensation coefficient for UML2 (medium mobility) is 0.5, and the first compensation coefficient for UML3 (low mobility) is 1.5. The second compensation coefficient is positively correlated with the beam stability level; that is, the more stable the beam, the larger the second compensation coefficient, thus extending the validity period of the associated ID. For example, the second compensation coefficient for BSL1 (stable) is 2.0 (good environment, extending validity period); the second compensation coefficient for BSL2 (medium) is 1.0 (no compensation); and the second compensation coefficient for BSL3 (unstable) is 0.4 (poor environment, shortening validity period).

[0097] Specifically, the effective duration can be calculated using the following formula:

[0098]

[0099] Where T represents the effective duration, BT represents the base duration, α represents the first compensation coefficient, and β represents the second compensation coefficient.

[0100] It should be noted that, in this embodiment, the network device determines the validity period based on mobility level and stability level as an example. When there are other factors that affect the validity of the first identifier, the validity period of the first identifier can also be determined by referring to other factors. This embodiment does not limit this further.

[0101] S203: The network device sends a first signaling message to the terminal device, and the terminal device receives the first signaling message accordingly. The first signaling message includes a first identifier and a first validity period.

[0102] The first identifier is the association ID assigned by the network device to the terminal device, and the first signaling can be RRC reconfiguration signaling.

[0103] S204: The terminal device manages the validity of the first identifier based on the first validity period.

[0104] In this embodiment, after receiving the first signaling, the terminal device obtains the associated ID and the first valid duration corresponding to the associated ID from the first signaling, so as to manage the associated ID based on the first valid duration.

[0105] Specifically, upon receiving the associated ID, the terminal device can immediately start a timer and configure its duration as the first valid duration. Thus, if the timer-recorded duration falls within the first valid duration, the terminal device marks the associated ID as valid; if the timer-recorded duration does not fall within the first valid duration, the terminal device marks the associated ID as invalid. In other words, if the timer does not time out, the associated ID is valid; if the timer times out, the associated ID is invalid.

[0106] Furthermore, if the associated ID is marked as invalid, the terminal device will stop using the AI / ML model corresponding to that associated ID to avoid degrading communication performance due to continued use of the model. Simultaneously, the resources it occupies can be released or marked as releaseable to prevent resource waste caused by occupying resources when the associated ID is invalid.

[0107] In some implementations, if the UE detects a change in its mobility level, such as from stationary to high mobility, it will report the changed mobility level to the network device so that the network device can determine a new validity period based on the changed mobility level. Specifically, the terminal device sends a third signaling message to the network device, which includes the changed mobility level. Accordingly, the network device receives the third signaling message and determines a second validity period based on the changed mobility level and the beam stability level, and sends a fourth signaling message to the terminal device, which includes the second validity period. Accordingly, the terminal device receives the fourth signaling message and manages the validity of the first identifier based on the second validity period.

[0108] It should be noted that the beam stability level may also change. When the network device determines a new validity period based on the changed mobility level, if the beam stability level also changes, the new validity period will be determined using both the changed mobility level and the changed stability level. In other words, the network device can adjust the validity period of the associated ID in a timely manner according to the real-time changes in the environment on the UE side to ensure that the resources corresponding to the associated ID are applicable to the current environment and to ensure the reliability of the associated ID.

[0109] In some implementations, if a cell handover occurs at the terminal device within the first effective duration, the method further includes:

[0110] The terminal device sends a handover request to the network device. Correspondingly, the network device receives the handover request and sends a fifth signaling message to the terminal device. This fifth signaling message includes indication information, which indicates whether the first identifier can continue to be used in the cell after the handover. The indication information can be determined through interaction between the source network device and the destination network device. Alternatively, the source network device can obtain the associated ID used by the destination network device, and then determine whether the associated ID includes the first identifier, obtaining the indication information based on the determination result. The specific method for determining the indication information is not limited in this embodiment.

[0111] Specifically, if the cell mode corresponding to the first identifier is single-cell mode, the indication information indicates that the first identifier is not applicable to the cell after handover. Here, single-cell mode means that the first identifier is bound to the network resource configuration of only one cell. If the cell mode corresponding to the first identifier is multi-cell mode and the multi-cell mode includes the cell after handover, the indication information indicates that the first identifier is applicable to the cell after handover. If the cell mode corresponding to the first identifier is multi-cell mode and the multi-cell mode does not include the cell after handover, the indication information indicates that the first identifier is not applicable to the cell after handover. Here, multi-cell mode means that the first identifier can be bound to the network resource configuration of multiple cells.

[0112] After receiving the fifth signaling, the terminal device manages the first identifier according to the indication information. Specifically, if the indication information indicates that the first identifier can continue to be used, the terminal device will continue to use the resources corresponding to the first identifier after switching cells, and use these resources to train and infer AI / ML models. If the indication information indicates that the first identifier cannot continue to be used, the terminal device can forcibly end the timer and release the resources corresponding to the first identifier. When the terminal device switches to the target cell, the network device in the target cell reassigns a second identifier to the terminal device, determines the third validity period corresponding to the second identifier, and sends the second identifier and the third validity period to the terminal device.

[0113] For example, Figure 3The diagram illustrates the cell handover process when a handover occurs before the timer expires. The UE's source gNB reports UE assistance information (UAI). The source gNB interacts with the target gNB based on the UAI to obtain the interaction result. If the interaction is in multi-cell mode, the UE is notified to use the association ID issued by the source gNB, and the model corresponding to the association ID is trained and inferred. If the UE leaves the cell, the UE is notified that the association ID issued by the source gNB is incompatible, the timer is forcibly terminated, and related resources are released. When the UE hands over to the target cell, the target gNB corresponding to the target cell reissues the association ID and its validity period to the UE. Situations involving leaving the cell include: handover from multiple cells to a single cell or other unrelated multiple cells, and handover from a single cell to another cell.

[0114] For a better understanding of the specific implementation of this application, please refer to [link / reference]. Figure 4 The initial configuration phase signaling interaction diagram shown is as follows: Figure 5 The signaling interaction diagram for the dynamic adaptation phase is shown.

[0115] Figure 4 The initial configuration phase shown includes the following processes:

[0116] S1: gNB collects implicit information.

[0117] The description of gNB collecting implicit information can be found in the description of the initial state in the above embodiments.

[0118] S2: gNB infers the initial UML and BSL based on implicit information, and determines the VPI based on the UML and BSL.

[0119] S3: gNB sends RRC reconfiguration signaling to UE.

[0120] S4: UE stores associated ID and VPI.

[0121] S5: The UE manages the validity of the associated ID based on the VPI.

[0122] Figure 5 The dynamic adaptation phase shown includes the following processes:

[0123] S6: The UE detects a change in the UML and obtains the current UML.

[0124] S7: The UE sends an RRC signaling message to the gNB, which carries the current UML.

[0125] S8: gNB redetermines the new effective duration VPI based on the current UML.

[0126] S9: gNB sends RRC reconfiguration signaling to UE, which only carries the new VPI.

[0127] It should be noted that in this case, the associated ID remains unchanged, only the VPI changes.

[0128] S10: The UE manages the validity of the associated ID according to the new VPI.

[0129] After receiving a new VPI, the UE restarts the timer and can send the execution result back to the gNB.
