The wireless communication system 100 may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120. The network device 110 can provide network coverage for a specific geographical area and can communicate with the terminal device 120 located within that coverage area. The terminal device 120 can access a network (such as a wireless network) through the network device 110. Optionally, the wireless communication system 100 may also include other network entities such as a network controller and a mobility management entity; this embodiment of the application does not limit this.

[0026] Types of SRBs

[0027] In related technologies, the communication system standards developed by the 3rd Generation Partnership Project (3GPP) divide radio bearers into two categories: SRBs and DRBs. SRBs can be used to transmit control information, such as radio resource control (RRC) messages. Each RRC message can carry a maximum of 9KB of data. Furthermore, SRBs use serial transmission technology; for example, a new RRC message transmission is not allowed until all segments of an RRC message have been successfully transmitted. DRBs, on the other hand, are generally established by access network devices in response to requests from core network devices and are primarily for application layer service transmissions. In other words, DRBs are typically used to perform application layer data transmission tasks.

[0028] For newly generated data transmission services within the communication system (e.g., model iteration training tasks, model training dataset transmission tasks, measurement result collection tasks, model transmission tasks, model parameter transmission tasks, etc.), the starting and ending points of these data transmission services are highly flexible. These data transmission services can originate from the access stratum (AS) layer of the terminal equipment to the access network equipment, or from the AS layer of the terminal equipment to the core network equipment, or from the access network equipment to the AS layer of the terminal equipment, etc. Since much of the collected data primarily involves AS layer functions, this collected data may have its data transmission format defined through RRC messages. Generally, data defined through RRC messages is transmitted via SRB. On the one hand, because data transmission tasks such as model training datasets may involve large amounts of data (typically reaching tens of megabytes to several gigabytes), relying entirely on SRB messages to transmit such large-capacity data could easily cause SRB congestion. On the other hand, even if the transmitted RRC message segments are few, the serial transmission mode of the SRB may still cause queuing delays in the RRC messages, thus resulting in data transmission delays. Therefore, how to avoid or mitigate SRB data transmission congestion and how to reduce SRB data transmission latency are technical problems that need to be solved.

[0029] Transmitting model training datasets via DRB offers several advantages. First, model training datasets typically record raw sample data, whose characteristics more closely resemble the actual communication environments experienced by terminal devices. Therefore, transmitting model training datasets allows terminal devices to train AI models that more closely reflect reality using raw sample data, making it easier for the model's performance to meet the demands of real-world communication environments. Second, most data types involved in model training datasets (such as reference signal received power (RSRP) measurements) do not have high privacy protection requirements (except for information like the terminal device's location). Directly transmitting model training datasets reduces the risk of leaking the sender's trade secrets.

[0030] Transmitting measurement-related data via DRB has the following advantages. Firstly, the measurement data obtained by a single device (e.g., a terminal device or network device) through the measurement process is very limited, but the optimization of measurement-related algorithms or the training of measurement-related AI models generally requires a large amount of measurement data. Transmitting measurement-related data via DRB enables measurement data sharing among multiple devices, improving the efficiency of a single device in acquiring measurement-related data. Secondly, because the data source is relatively random, the generalization ability of measurement-related data is better (or the quality of measurement-related data is higher), making it easier to obtain high-quality optimization algorithms or high-performance AI models using such data.

[0031] Transmitting model-type data via DRB has the following advantages: If the data recipient uses the received model to perform model training tasks, transmitting model-type data via DRB allows the model trainer to train the required AI model more quickly. If the data recipient uses the received model to perform specific communication functions, it saves the data recipient the work of training that type of AI model itself. Especially for terminal devices with limited computing power, obtaining AI models from network devices is more in line with business realities than training AI models themselves.

[0032] Transmitting model parameter data via DRB has the following effects: If the recipient of the model parameter data uses the received model parameters to perform a model training task, transmitting model parameter data via DRB allows the model trainer to train the required AI model more quickly. If the recipient of the model parameter data uses the received model parameters to replace existing model parameters, transmitting model parameter data via DRB allows the recipient to quickly update its deployed AI model, thereby regaining communication gains through the AI ​​model in a shorter time.

[0033] Transmitting terminal device capability-related data via DRB has the following advantages: It can prevent SRB congestion when the amount of data related to the terminal device's capabilities is large.

[0034] As can be seen from the above description, in related technologies, how to avoid or mitigate congestion of SRB transmission data and how to reduce the latency of SRB transmission data are technical problems that need to be solved.

[0035] To address the aforementioned issues, this application provides a communication method. Using this method, an association can be established between a set of DRBs and one or more SRBs, enabling the transmission of control information associated with one or more SRBs using a set of DRBs. The DRB can also serve as a data transmission channel to transmit control information carried by the SRB. On one hand, when the amount of control information to be transmitted is large, SRB congestion can be reduced or avoided. On the other hand, the queuing delay of the control information to be transmitted can be reduced. Furthermore, in scenarios involving changing serving cells, transmitting control information via DRBs can achieve lossless data transmission, whereas related technologies do not support lossless data transmission in mobility scenarios using SRBs.

[0036] The communication method provided in the embodiments of this application will be described in detail below with reference to Figure 2.

[0037] Figure 2 is a schematic flowchart of a communication method provided in an embodiment of this application. The method in Figure 2 is described from the perspective of a terminal device. The terminal device in Figure 2 can be the terminal device 120 mentioned above. This terminal device can be used to communicate with network devices. The terminal device can be, for example, a UE.

[0038] Referring to Figure 2, the communication method provided in this application embodiment may include the following step S210.

[0039] In step S210, the terminal device receives the first information sent by the network device; correspondingly, the network device sends the first information to the terminal device.

[0040] The first information here can be used to configure a set of DRBs. This can also be understood as the first information being used to configure a set of user plane bearers or a set of data plane bearers. User plane bearers or data plane bearers can be DRBs or other radio bearers (RBs) with similar functions to DRBs. This application embodiment uses the example of the first information being used to configure a set of DRBs for illustration. It should be understood that the description related to DRBs can also be replaced with user plane bearers or data plane bearers, and this application embodiment does not limit this. A set of DRBs can contain one DRB. Alternatively, a set of DRBs can contain multiple DRBs. In some scenarios, a set of DRBs can be used to transmit control information associated with an SRB (corresponding to Scenario 1 below). In other scenarios, a set of DRBs can be used to transmit control information associated with an SRB (corresponding to Scenario 2 below). The control information here can include RRC messages. RRC messages can include, for example, reconfiguration messages, messages recording quality of experience (QoE) related information, etc. The control information here can also be understood as data. In some cases, "SRB-associated control information" can include or be replaced with SRB-associated data. For a more detailed introduction to SRB and DRB, please refer to the relevant sections above; they will not be repeated here.

[0041] Optionally, in some embodiments, a DRB can be used to transmit control information associated with an SRB.

[0042] Alternatively, in other embodiments, a DRB can be used to transmit control information associated with a set of SRBs.

[0043] Alternatively, in other embodiments, multiple DRBs can be used to transmit control information associated with an SRB.

[0044] Alternatively, in other embodiments, multiple DRBs can be used to transmit control information associated with a set of SRBs.

[0045] The association between SRBs and control information can be determined based on predefined information in the protocol. Alternatively, the association between SRBs and control information can be determined based on the protocol's default settings.

[0046] Typically, the protocol specifies which control information (such as RRC messages) should be transmitted through which SRB. For example, reconfiguration messages can be transmitted through SRB1 or SRB3, and QoE-related messages can be transmitted through SRB4 or SRB5. Therefore, once it is clear which set of data radio bearers is associated with which type or set of SRBs, the terminal device can determine which types of control information should be transmitted by the DRB associated with that type or set of SRBs.

[0047] As described in step S210, this embodiment of the application establishes an association between a set of DRBs and one or more SRBs, enabling the transmission of control information associated with one or more SRBs using a set of DRBs. On one hand, this method provides different data transmission channels for the control information (or data) transmitted by the SRBs. In this way, when signaling transmission congestion occurs in the SRB, it can switch to another data transmission channel (i.e., the DRB) to complete the data transmission, thereby alleviating the situation where data transmission is delayed due to SRB signaling transmission congestion. On the other hand, it can reduce or avoid SRB congestion caused by excessively large amounts of data transmitted by the SRB. In related technologies, SRBs use serial transmission technology. For example, a new RRC message transmission is not allowed until all segments of an RRC message have been successfully transmitted. As a result, if there is a large amount of RRC content to be transmitted, it will lead to too many RRC message segments to be transmitted, and these excessive RRC message segments will block subsequent RRC message transmissions before successful transmission. Transmitting larger RRC messages through DRBs can effectively avoid SRB congestion.

[0048] Step S210 mentions that in some scenarios, a set of DRBs can be used to transmit control information associated with an SRB (corresponding to Scenario 1 below). In other scenarios, a set of DRBs can be used to transmit control information associated with a set of SRBs (corresponding to Scenario 2 below). To establish the association between a set of DRBs and one or more SRBs, this application provides six implementation methods for Scenario 1 and eight implementation methods for Scenario 2. In these fourteen implementation methods, the association between a set of DRBs and one or more SRBs is established explicitly or implicitly, thereby realizing the function of transmitting control information associated with one or more SRBs using a set of DRBs. The following describes in detail the six implementation methods for Scenario 1 and the eight implementation methods for Scenario 2, with specific examples.

[0049] In the following description, the terms "bearer identifier" and "bearer identifier information" are used. It should be understood that in the embodiments of this application, "bearer identifier" and "bearer identifier information" can be used interchangeably. In the following description, the terms "bearer group identifier" and "bearer group identifier information" are also used. It should be understood that in the embodiments of this application, "bearer group identifier" and "bearer group identifier information" can be used interchangeably.

[0050] Scenario 1: A group of DRBs is used to transmit control information associated with an SRB.

[0051] In scenario one, a set of DRBs can be used to transmit control information associated with an SRB.

[0052] Optionally, in some embodiments, there can be a one-to-one association between SRBs and DRBs. In this case, a group of DRBs contains one DRB, and control information associated with an SRB can be transmitted through a DRB associated with that SRB.

[0053] Alternatively, in other embodiments, the relationship between an SRB and a DRB can be one-to-many. In this case, a group of DRBs can contain at least two DRBs, and control information associated with an SRB can be transmitted through at least two DRBs associated with that SRB.

[0054] In Scenario 1, there are multiple ways to configure the association between an SRB and a group of DRBs. This application provides six possible implementation methods. The following sections will describe these six possible implementation methods in detail with specific examples.

[0055] The first implementation method of scenario one

[0056] In the first implementation of Scenario 1, the first information may include the bearer identifier corresponding to the SRB, and the bearer identifiers corresponding to one or more DRBs associated with the SRB. Alternatively, the first information may include the bearer identifier corresponding to the SRB, and the bearer group identifier information corresponding to one or more DRBs associated with the SRB.

[0057] Here, an SRB can be understood as an SRB that is associated with a set of DRBs out of n (n is a positive integer) SRBs configured by the network device for the terminal device. For ease of description, an SRB associated with a set of DRBs can be called a Type I SRB. Each Type I SRB can be associated with one or more DRBs. Or, each Type I SRB can be associated with a set of DRBs. Different Type I SRBs can be associated with different DRBs. In addition to Type I SRBs, the n SRBs configured by the network device for the terminal device may also include Type II SRBs. Type II SRBs can be understood as SRBs that are not associated with any DRBs.

[0058] In some cases, each of the one or more DRBs associated with a Type 1 SRB may correspond to a bearer identifier. In other cases, one or more DRBs associated with a Type 1 SRB (i.e., a group of DRBs associated with a Type 1 SRB) may correspond to a bearer group identifier.

[0059] In the first implementation of Scenario 1, the association between an SRB and a group of DRBs can be determined by the bearer identifier or bearer group identifier information corresponding to one or more DRBs associated with the SRB.

[0060] To facilitate understanding, the following explanation is provided in conjunction with Table 1. Table 1 shows an example of the first implementation method for Scenario 1.

[0061] Table 1. Examples of the first implementation method for Scenario 1

[0062] In Table 1, the network device configures n (n is a positive integer) SRBs for the terminal device, some of which are associated with a group of DRBs. For ease of description, SRBs associated with a group of DRBs are called Type 1 SRBs, and SRBs not associated with any DRBs are called Type 2 SRBs. When configuring any SRB belonging to Type 1 SRBs, the configuration parameters related to the SRB include the bearer identifier information corresponding to the SRB, second information, and other configuration parameters related to the SRB. The second information includes the bearer identifier information corresponding to one or more DRBs associated with the SRB, or the bearer group identifier corresponding to a group of DRBs associated with the SRB. When configuring any SRB belonging to Type 2 SRBs, the configuration parameters related to the SRB include the bearer identifier information corresponding to the SRB and other configuration parameters related to the SRB. These other configuration parameters include at least the protocol layer configuration implementing the SRB. For example, the protocol layer configuration implementing the SRB includes Packet Data Convergence Protocol (PDCP) layer configuration information and / or other protocol layer configuration information. In the example shown in Table 2A, the association between an SRB and a group of DRBs is achieved through the bearer identification information corresponding to one or more DRBs or the bearer group identification information corresponding to a group of DRBs.

[0063] As mentioned above, the protocol layer configuration for implementing SRB can include PDCP layer configuration information and / or other protocol layer configuration information. These other protocol layer configuration information may include Service Data Adaptation Protocol (SDAP) layer configuration information. Of course, if the functions of the PDCP protocol layer and the radio link control (RLC) protocol layer are merged to define a new protocol layer (hereinafter referred to as the first protocol layer), then the protocol layer configuration for implementing SRB can include the first protocol layer configuration information and / or other protocol layer configuration information. The explanations of other SRB-related configuration parameters here apply throughout the text and will not be repeated elsewhere.

[0064] The configuration in Table 1 clearly shows which DRB(s) each SRB belonging to the first type of SRB is associated with (the association between the two is determined by the bearer identifier or bearer group identifier corresponding to one or more DRBs associated with the SRB), but the configuration parameters related to one or more DRBs associated with an SRB are not given in Table 1.

[0065] In the first implementation of Scenario 1, the first information may also include DRB-related configuration parameters. These DRB-related configuration parameters can include two scenarios. In the first scenario, the first information may also include one or more DRB-related configuration parameters associated with the SRB. In the second scenario, the first information may also include one or more sets of DRB-related configuration parameters, as well as bearer group identifier information corresponding to the first target DRB group. These two scenarios are explained below with reference to Tables 2A and 2B.

[0066] In the first scenario, the first information may further include one or more DRB-related configuration parameters associated with the SRB. These DRB-related configuration parameters may include the bearer identifier corresponding to the DRB and the protocol layer configuration implementing the DRB. Alternatively, the DRB-related configuration parameters may include the bearer identifier corresponding to the DRB, the bearer group identifier corresponding to the DRB, and the protocol layer configuration implementing the DRB.

[0067] As mentioned earlier, in the first implementation of Scenario 1, the first information may include the bearer identifier corresponding to the SRB, and the bearer identifiers corresponding to one or more DRBs associated with the SRB. Alternatively, the first information may include the bearer identifier corresponding to the SRB, and the bearer group identifier information corresponding to one or more DRBs associated with the SRB.

[0068] When the first information includes the bearer identifier corresponding to the SRB and the bearer identifiers corresponding to one or more DRBs associated with the SRB, the configuration parameters related to the DRB may include the bearer identifier corresponding to the DRB and the protocol layer configuration for implementing the DRB.

[0069] When the first information includes the bearer identifier corresponding to the SRB and the bearer group identifier information corresponding to one or more DRBs associated with the SRB, the configuration parameters related to the DRB may include the bearer identifier corresponding to the DRB, the bearer group identifier corresponding to the DRB, and the protocol layer configuration for implementing the DRB.

[0070] The bearer group identifier corresponding to a DRB can be used to associate a group of DRBs together. That is, one or more DRBs associated with the same bearer group identifier can be referred to as the same group of DRBs. In some cases, the bearer group identifier can also be called a session identifier, task identifier, or index identifier. Bearer group identifiers, session identifiers, task identifiers, and index identifiers can all be used to associate a group of DRBs together. The explanation of the bearer group identifier here applies throughout the text and will not be repeated elsewhere.

[0071] The protocol layer configuration for implementing DRB can include PDCP layer configuration information and / or other protocol layer configuration information. These other protocol layer configuration information may include SDAP layer configuration information. Of course, if a new protocol layer (hereinafter referred to as the first protocol layer) is defined by merging the functions of the PDCP protocol layer and the RLC protocol layer, then the protocol layer configuration for implementing DRB can include the first protocol layer configuration information and / or other protocol layer configuration information. This explanation of the protocol layer configuration for implementing DRB applies throughout the entire text and will not be repeated elsewhere.

[0072] In the first case, the association between an SRB and a group of DRBs can be achieved through one or more bearer identifiers corresponding to DRBs or a group of bearer group identifiers corresponding to a group of DRBs.

[0073] For ease of understanding, the following explanation is based on Table 2A. Table 2A shows Example 1 of the DRB-related configuration parameters in the first implementation method of Scenario 1 (corresponding to the first case).

[0074] Example 1 of DRB-related configuration parameters in the first implementation method of Scenario 1 in Table 2A

[0075] In Table 2A, the network device configures m (m is a positive integer) DRBs for the terminal device. The configuration parameters related to the DRBs include the bearer identifier information corresponding to the DRB and other configuration parameters related to that DRB. Alternatively, the configuration parameters related to the DRBs include the bearer identifier information corresponding to the DRB, the bearer group identifier information corresponding to the DRB, and other configuration parameters related to that DRB. The bearer group identifier information corresponding to the DRB is used to associate a group of DRBs together; that is, one or more DRBs associated with the same bearer group identifier are referred to as the same group of DRBs. Other configuration parameters related to the DRBs include at least the protocol layer configuration for implementing the DRB. In the example in Table 2A, the association between an SRB and a group of DRBs is achieved through one or more bearer identifier information or bearer group identifier information corresponding to the DRB.

[0076] The first scenario of DRB-related configuration parameters in the first implementation method of Scenario 1 has been introduced above with reference to Figure 2A. The second scenario of DRB-related configuration parameters in the first implementation method of Scenario 1 will be introduced below with reference to Figure 2B.

[0077] In the second scenario, the first information may further include one or more sets of DRB-related configuration parameters, as well as bearer group identification information corresponding to the first target DRB group. Here, the first target DRB group can be understood as any one of the one or more DRB groups.

[0078] The group or multiple DRBs mentioned here can be understood as a group or multiple DRBs configured by the network device for the terminal device. Each DRB in the group or multiple DRBs can be associated with a bearer group identifier.

[0079] The configuration parameters related to DRB can include the bearer identifier corresponding to the DRB, as well as the protocol layer configuration for implementing the DRB.

[0080] In the second case, the association between an SRB and a group of DRBs is achieved through the bearer group identifier corresponding to a group of DRBs.

[0081] For ease of understanding, the following explanation is based on Table 2B. Table 2B shows Example 2 of the DRB-related configuration parameters in the first implementation method of Scenario 1 (corresponding to the second case).

[0082] Table 2B Example 2 of DRB-related configuration parameters in the first implementation method of Scenario 1

[0083] In Table 2B, the network device configures k (k is a positive integer) DRBs for the terminal device, and each DRB is associated with a bearer group identifier. Each DRB group includes one or more DRBs. The configuration parameters related to the DRB include the bearer identifier information corresponding to the DRB and other configuration parameters related to the DRB. Among them, the other configuration parameters related to the DRB include at least the protocol layer configuration that implements the DRB. In the example shown in Table 2B, the association between an SRB and a group of DRBs is achieved through the bearer group identifier corresponding to a group of DRBs.

[0084] In the first implementation of Scenario 1, the association between SRB-related configurations and DRB-related configurations can be achieved with a small number of parameters (the bearer identifier or bearer group identifier corresponding to the DRB), and the protocol-related modifications are minimal.

[0085] The second implementation method of scenario one

[0086] In the second implementation of Scenario 1, the first information may include the bearer identifier corresponding to the DRB and the bearer identifier corresponding to an SRB associated with the DRB.

[0087] Here, a DRB can be understood as a DRB associated with one SRB out of the m (m is a positive integer) DRBs configured by the network device for the terminal device. For ease of description, a DRB associated with one SRB can be called a Type I DRB. Each Type I DRB can be associated with one SRB. Different Type I DRBs can be associated with the same SRB. Alternatively, different Type I DRBs can be associated with different SRBs. In addition to Type I DRBs, the m DRBs configured by the network device for the terminal device may also include Type II DRBs. Type II DRBs can be understood as DRBs that are not associated with any SRBs.

[0088] In the second implementation of Scenario 1, the association between an SRB and a group of DRBs can be determined by the bearer identifier corresponding to an SRB associated with a DRB.

[0089] To facilitate understanding, Table 3 is used as a reference below. Table 3 shows an example of the second implementation method for Scenario 1.

[0090] Table 3 Examples of the second implementation method for Scenario 1

[0091] In Table 3, the network device configures m (m is a positive integer) DRBs for the terminal device, some of which are associated with an SRB. For ease of description, a DRB associated with an SRB is called a Type 1 DRB, and a DRB not associated with any SRB is called a Type 2 DRB. When configuring any Type 1 DRB, the configuration parameters related to the DRB include the bearer identifier information corresponding to the DRB, third information, and other configuration parameters related to the DRB. The third information includes the bearer identifier information corresponding to the SRB associated with the DRB associated with the third information. When configuring any Type 2 DRB, the configuration parameters related to the DRB include the bearer identifier information corresponding to the DRB and other configuration parameters related to the DRB. These other configuration parameters include at least the protocol layer configuration for implementing the DRB. In the example shown in Table 3, different Type 1 DRBs may be associated with the same or different SRBs.

[0092] The configuration in Table 3 clearly shows which SRB each DRB belonging to the first type of DRB is associated with (the association between the two is determined by the bearer identifier corresponding to the SRB associated with the DRB), but the configuration parameters related to the SRB associated with the DRB are not given in Table 3.

[0093] In the second implementation of Scenario 1, the configuration parameter of an SRB associated with DRB can be either not configured for the terminal device or configured for the terminal device.

[0094] Optionally, in some embodiments, the configuration parameters related to an SRB associated with a DRB are not configured for the terminal device. That is, the SRB associated with the DRB is not actually established. Since the protocol already specifies which control information (e.g., RRC messages) can be transmitted through which SRB, after configuring a set of DRBs associated with a corresponding SRB, the terminal device can transmit the control information (e.g., RRC messages) associated with the SRBs of that set of DRBs through that set of DRBs. It is unnecessary to configure the corresponding SRBs simultaneously with configuring a set of DRBs associated with SRBs, as performing the same data transmission task through two bearers is not an efficient resource utilization method. In this approach, the configuration overhead is small, and resource utilization efficiency is high.

[0095] Optionally, in other embodiments, the configuration parameters related to an SRB associated with the DRB can be configured for the terminal device. That is, the SRB associated with the DRB is still actually established. Although this method is not very resource efficient, it allows for parallel transmission of control information (e.g., RRC messages) through a backup radio bearer when congestion occurs. For example, RRC message 1 is transmitted via SRB1, where RRC message 1 is divided into 10 data segments. While the terminal device is still transmitting the fifth data segment of RRC message 1, RRC message 2 carried by SRB1 (e.g., RRC message 2 carries emergency indication information such as overheating alarms on the terminal device side) needs to be urgently sent to the network device. In related technologies, the terminal device needs to wait until all data segments of RRC message 1 are successfully transmitted before it can start transmitting RRC message 2. This RRC message transmission mechanism causes delays in the network device's response to the terminal device's emergency requests, which is detrimental to the user experience. In this scenario, the transmission of RRC message 2, which is likely to be congested, through the DRB associated with SRB1 can effectively ensure that RRC message 2 is transmitted to the network device in a timely manner, reducing the waiting time for RRC message 2 in this scenario and optimizing the user experience.

[0096] To facilitate understanding, Table 4 is used as a reference below. Table 4 shows an example of SRB-related configuration parameters in the second implementation method of Scenario 1. In the example in Table 4, an SRB associated with the DRB is still actually established.

[0097] Table 4 shows examples of SRB-related configuration parameters in the second implementation method of Scenario 1.

[0098] In Table 4, the network device configures n (n is a positive integer) SRBs for the terminal device. The configuration parameters related to the SRB include the bearer identification information corresponding to the SRB and other configuration parameters related to the SRB. Among them, the other configuration parameters related to the SRB include at least the protocol layer configuration for implementing the SRB.

[0099] In the second implementation of Scenario 1, the association between an SRB and a group of DRBs can be determined by the bearer identifier corresponding to an SRB associated with a DRB. The terminal device can then clearly know which DRB(s) the control information associated with a certain SRB can be transmitted through.

[0100] In the second implementation of Scenario 1, the association between an SRB and a group of DRBs can be determined with a small number of parameters (the bearer identifier corresponding to the SRB), and the protocol-related modifications are minimal.

[0101] The third implementation method of scenario one

[0102] In the third implementation of Scenario 1, the first information may include one or more sets of DRB-related configuration parameters, and a bearer identifier corresponding to an SRB associated with the second target DRB. Here, the second target DRB can be understood as any one of the one or more DRB sets.

[0103] This set of one or more DRBs can be understood as a set of one or more DRBs configured by the network device for the terminal device. Each DRB in this set of one or more DRBs (i.e., the second target DRB) can be associated with an SRB. An SRB can correspond to a bearer identifier.

[0104] The configuration parameters related to DRB can include the bearer identifier corresponding to the DRB, as well as the protocol layer configuration for implementing the DRB.

[0105] To facilitate understanding, the following explanation is provided in conjunction with Table 5. Table 5 shows an example of the third implementation method for Scenario 1.

[0106] Table 5 shows an example of the third implementation method for Scenario 1.

[0107] In Table 5, the network device configures k (k is a positive integer) DRBs for the terminal device, and each DRB is associated with one SRB. Each DRB group includes one or more DRBs. The configuration parameters related to the DRB include the bearer identification information corresponding to the DRB and other configuration parameters related to the DRB. Among them, the other configuration parameters related to the DRB include at least the protocol layer configuration for implementing the DRB.

[0108] The configuration in Table 5 clearly shows which SRB a group of DRBs is associated with (the association between the two is determined by the bearer identifier of the SRB associated with a group of DRBs), but the configuration parameters related to the SRB associated with a group of DRBs are not given in Table 5.

[0109] In the third implementation of Scenario 1, the configuration parameters of an SRB associated with a set of DRBs can be either not configured for the terminal device or configured for the terminal device.

[0110] Optionally, in some embodiments, the configuration parameters related to an SRB associated with a set of DRBs may not be configured for the terminal device. That is, the SRB associated with the DRB is not actually established.

[0111] Optionally, in other embodiments, configuration parameters related to an SRB associated with a set of DRBs can be configured for the terminal device. That is, an SRB associated with a DRB is still actually established. The configuration parameters related to the SRB can be referred to the description in Table 4, and will not be repeated here.

[0112] In the third implementation of Scenario 1, the association between an SRB and a set of DRBs is determined by the bearer identification information corresponding to an SRB associated with a set of DRBs. The terminal device can then clearly know which DRBs can transmit the control information associated with a certain SRB.

[0113] In the third implementation of Scenario 1, on the one hand, the association between an SRB and a group of DRBs can be determined with a small number of parameters (the bearer identifier corresponding to the SRB). On the other hand, configuring DRBs in groups saves more configuration overhead.

[0114] The fourth implementation method of scenario one

[0115] In the fourth implementation of Scenario 1, the first information may include the bearer identifier corresponding to the SRB, and a set of DRB-related configuration parameters associated with the SRB.

[0116] Here, an SRB can be understood as an SRB that is associated with a set of DRBs out of the n (n is a positive integer) SRBs configured by the network device for the terminal device. For ease of understanding, an SRB associated with a set of DRBs can be called a Type I SRB. Each Type I SRB can be associated with a set of DRBs. Or, each Type I SRB can be associated with one or more DRBs. Different Type I SRBs can be associated with different DRBs. In addition to Type I SRBs, the n (n is a positive integer) SRBs configured by the network device for the terminal device may also include Type II SRBs. Type II SRBs can be understood as SRBs that are not associated with any DRBs.

[0117] The configuration parameters related to DRB can include the bearer identifier corresponding to the DRB, as well as the protocol layer configuration for implementing the DRB.

[0118] In this implementation, the association between an SRB and a set of DRBs can be directly determined based on the bearer identifier corresponding to the SRB and the configuration parameters of a set of DRBs associated with that SRB.

[0119] To facilitate understanding, Table 6 is used as a reference below. Table 6 shows an example of the fourth implementation method for Scenario 1.

[0120] Table 6 shows an example of the fourth implementation method for Scenario 1.

[0121] In Table 6, the network device configures n (n is a positive integer) SRBs for the terminal device, some of which are associated with a set of DRBs. For ease of description, SRBs associated with a set of DRBs are called Type 1 SRBs, and SRBs not associated with any DRBs are called Type 2 SRBs. When configuring any SRB belonging to Type 1 SRBs, the SRB-related configuration parameters include the bearer identifier information corresponding to the SRB, the fourth information, and other configuration parameters related to the SRB. The fourth information includes the configuration parameters related to the set of DRBs associated with the SRB. The DRB-related configuration parameters include at least the bearer identifier corresponding to the DRB and the protocol layer configuration for implementing the DRB. When configuring any SRB belonging to Type 2 SRBs, the SRB-related configuration parameters include the bearer identifier information corresponding to the SRB and other configuration parameters related to the SRB. The other configuration parameters related to the SRB include the protocol layer configuration for implementing the SRB. In the example shown in Table 6, each SRB belonging to Type 1 SRBs is associated with a different DRB.

[0122] In the example shown in Table 6, since the configuration parameters related to the SRB directly include the configuration parameters related to a set of DRBs associated with the SRB, the association between an SRB and a set of DRBs can be determined solely through the configuration in Table 6. The terminal device can then clearly know which DRBs can transmit the control information associated with each SRB belonging to the first type of SRB.

[0123] In the fourth implementation of Scenario 1, the SRB-related configurations are directly associated with the DRB-related configurations, eliminating the need to indirectly determine the association between an SRB and a group of DRBs through the bearer identifier corresponding to the SRB, or the bearer identifier or bearer group identifier corresponding to the DRB. Therefore, the fourth implementation of Scenario 1 saves more configuration overhead.

[0124] The fifth implementation method of scenario one

[0125] In the fifth implementation of Scenario 1, the first information may include one or more first parameters.

[0126] The first parameter can be used to indicate a set of DRB-related configuration parameters. In other words, the first parameter can be used to configure a set of DRBs. A network device can configure k (k is a positive integer) DRBs for a terminal device. These k DRBs can be configured sequentially using k first parameters.

[0127] The first parameter indicates a set of DRBs (or a set of DRBs configured by the first parameter) that can be used to transmit control information associated with an SRB determined based on protocol predefined information. In other words, different first parameters can be associated with different SRBs, and the SRB associated with the first parameter can be determined based on protocol predefined information (or, in other words, through protocol defaults). Protocol predefined information may include the predefined location of the first parameter within the protocol. That is, the location of the first parameter within the protocol determines which SRB-associated control information the set of DRBs configured by that first parameter is used to transmit.

[0128] The configuration parameters related to DRB can include the bearer identifier corresponding to the DRB, as well as the protocol layer configuration for implementing the DRB.

[0129] To facilitate understanding, the following explanation is provided in conjunction with Table 7. Table 7 shows an example of the fifth implementation method for Scenario 1.

[0130] Table 7 Example of the fifth implementation method for Scenario 1

[0131] In Table 7, the network device configures k (k is a positive integer) DRBs for the terminal device, and each DRB group includes one or more DRBs. The k DRBs are configured sequentially through parameters one through k. The target DRB in the k DRB groups is used to transmit control information associated with a specific SRB. The target DRB can be any one of the k DRB groups. Parameter k includes the configuration parameters related to the k-th DRB. The configuration parameters related to the DRB include the bearer identifier corresponding to the DRB and the protocol layer configuration for implementing the DRB. Different first parameters are associated with different SRB types.

[0132] For the configuration methods in Table 7, the protocol stipulates that parameter one is associated with SRB1, that is, a set of DRBs configured by parameter one is used to transmit control information associated with SRB1; the protocol stipulates that parameter two is associated with SRB2, that is, a set of DRBs configured by parameter two is used to transmit control information associated with SRB2; the protocol stipulates that parameter k is associated with SRBk, that is, a set of DRBs configured by parameter k is used to transmit control information associated with SRBk.

[0133] In the fifth implementation of Scenario 1, the configuration parameters of an SRB associated with a set of DRBs can be either not configured for the terminal device or configured for the terminal device.

[0134] Optionally, in some embodiments, the configuration parameters related to an SRB associated with a set of DRBs may not be configured for the terminal device. That is, the SRB associated with the DRB is not actually established.

[0135] Optionally, in other embodiments, configuration parameters related to an SRB associated with a set of DRBs can be configured for the terminal device. That is, an SRB associated with a DRB is still actually established. The configuration parameters related to the SRB can be referred to the description in Table 4, and will not be repeated here.

[0136] In the fifth implementation of Scenario 1, the overhead of configuration can be saved, and there is no need to update the SRB-related configuration parameters.

[0137] The sixth implementation method of scenario one

[0138] The sixth implementation method of Scenario 1 can include two cases. In the first case, the first information can include the bearer identifier corresponding to the DRB and the first indication information. In the second case, the first information can include one or more sets of DRB-related configuration parameters, as well as the first indication information associated with the third target group DRB. The following sections will describe these two cases in detail with reference to Tables 8A and 8B.

[0139] In the first scenario, the first information may include the bearer identifier corresponding to the DRB and first indication information. The first indication information may be used to indicate the type of SRB associated with the DRB.

[0140] Here, a DRB can be understood as a DRB that is associated with one SRB out of the m (m is a positive integer) DRBs configured by the network device for the terminal device. For ease of description, a DRB associated with one SRB can be called a Type I DRB. Each Type I DRB can be associated with one SRB. Different Type I DRBs can be associated with the same SRB type. Alternatively, different Type I DRBs can be associated with different SRB types. In addition to Type I DRBs, the m DRBs configured by the network device for the terminal device may also include Type II DRBs. Type II DRBs can be understood as DRBs that are not associated with any SRBs.

[0141] The first indication information can be associated with a DRB. The first indication information can be used to indicate the type of SRB associated with the DRB associated with the first indication information.

[0142] In the first case, the association between a group of DRBs and an SRB can be determined by the first indication information associated with each first type of DRB.

[0143] For ease of understanding, the following explanation is provided in conjunction with Table 8A. Table 8A shows Example 1 of the sixth implementation method for Scenario 1 (corresponding to the first case of the sixth implementation method for Scenario 1).

[0144] Example 1 of the sixth implementation method in Scenario 1 of Table 8A

[0145] In Table 8A, the network device configures m (m is a positive integer) DRBs for the terminal device, some of which are associated with an SRB. For ease of description, a DRB associated with an SRB is called a Type 1 DRB, and a DRB not associated with any SRB is called a Type 2 DRB. When configuring any Type 1 DRB, the configuration parameters related to the DRB include the bearer identifier information corresponding to the DRB, a first indication information, and other configuration parameters related to the DRB. The first indication information is used to indicate the SRB type associated with the DRB associated with the first indication information. When configuring any Type 2 DRB, the configuration parameters related to the DRB include the bearer identifier information corresponding to the DRB and other configuration parameters related to the DRB. These other configuration parameters include at least the protocol layer configuration for implementing the DRB.

[0146] The first scenario of the sixth implementation method for Scenario 1 has been described above with reference to Table 8A. The second scenario of the sixth implementation method for Scenario 1 will now be described below with reference to Table 8B.

[0147] In the second scenario, the first information may include one or more sets of DRB-related configuration parameters, as well as first indication information associated with the third target DRB group. Here, the third target DRB group can be understood as any one of the one or more DRB groups.

[0148] The group or multiple DRBs can be understood as a group or multiple DRBs configured by the network device for the terminal device. Each DRB in the group or multiple DRBs (i.e., the third target group DRB) can be associated with a first indication information, which can be used to indicate the type of SRB associated with that group of DRBs. In other words, the first indication information can be used to indicate the type of SRB associated with the group of DRBs associated with the first indication information. Or, a group of DRBs can be associated with a type of SRB through the first indication information.

[0149] The configuration parameters related to the DRB can include the bearer identifier information corresponding to the DRB, as well as other configuration parameters related to the DRB. These other configuration parameters can include the protocol layer configuration for implementing the DRB.

[0150] In the second case, the association between a group of DRBs and an SRB can be determined by the first indication information associated with each group of DRBs.

[0151] For ease of understanding, the following explanation is based on Table 8B. Table 8B shows Example 2 of the sixth implementation method for Scenario 1 (corresponding to the second case of the sixth implementation method for Scenario 1).

[0152] Example 2 of the sixth implementation method for Scenario 1 in Table 8B

[0153] In Table 8B, the network device configures k (k is a positive integer) DRBs for the terminal device. Each DRB is associated with a type of SRB through a first indication information. Each DRB group includes one or more DRBs. The configuration parameters related to the DRB include the bearer identification information corresponding to the DRB and other configuration parameters related to the DRB. Among them, the other configuration parameters related to the DRB include at least the protocol layer configuration for implementing the DRB.

[0154] For the first and second cases of the sixth implementation method in Scenario 1, both involve the first instruction information.

[0155] Optionally, in some embodiments, the first indication information can be an identification information (e.g., an ID identifier). The identification information can be different from the carrying identification information. Different values ​​of the identification information can correspond to different types of SRBs. For example, a value of '000' for the first indication information corresponds to SRB1, a value of '001' corresponds to SRB2, a value of '010' corresponds to SRB3, a value of '011' corresponds to SRB4, a value of '100' corresponds to SRB5, and so on.

[0156] Alternatively, in other embodiments, the first indication information can be implemented using the choice{} function. Each value of the choice{} function can correspond to a different type of SRB.

[0157] Alternatively, in other embodiments, the first indication information can be implemented using enumeration parameters. Each element of the enumeration parameters can correspond to a type of SRB.

[0158] The configuration in Table 8A or Table 8B clearly shows which SRB a group of DRBs is associated with (the association between the two is determined by the first indication information associated with a group of DRBs), but the configuration parameters related to an SRB associated with a group of DRBs are not given in Table 8A or Table 8B.

[0159] In the sixth implementation of Scenario 1, the configuration parameters of an SRB associated with a set of DRBs can be either not configured for the terminal device or configured for the terminal device.

[0160] Optionally, in some embodiments, the configuration parameters related to an SRB associated with a set of DRBs are not configured to the terminal device. That is, an SRB associated with a DRB is not actually established.

[0161] Optionally, in other embodiments, configuration parameters related to an SRB associated with a set of DRBs can be configured for the terminal device. That is, an SRB associated with a DRB is still actually established. The configuration parameters related to the SRB can be referred to the description in Table 4, and will not be repeated here.

[0162] In the sixth implementation of Scenario 1 (including Case 1 and Case 2), the association between an SRB and a set of DRBs can be determined through the first indication information associated with a set of DRBs. The terminal device can then clearly know which DRBs can transmit the control information associated with a certain SRB.

[0163] The sixth implementation method in Scenario 1 balances the flexibility of configuration with the size of the overhead, and does not require updating the SRB-related configuration parameters.

[0164] The above describes six implementation methods for Scenario 1. Below, we will introduce eight implementation methods for Scenario 2.

[0165] Scenario 2: A set of DRBs is used to transmit control information associated with a set of SRBs.

[0166] In Scenario 2, a set of DRBs can be used to transmit control information associated with a set of SRBs. In Scenario 2, the association relationship between SRBs and DRBs can be any of the following: one-to-one association, one-to-many association, many-to-one association, or many-to-many association.

[0167] Optionally, in some embodiments, there can be a one-to-one association between SRBs and DRBs. In this case, a group of DRBs may contain one DRB, and control information associated with an SRB can be transmitted through a DRB associated with that SRB.

[0168] Alternatively, in other embodiments, the relationship between an SRB and a DRB can be one-to-many. In this case, a DRB group can contain at least two DRBs, and control information associated with an SRB can be transmitted through at least two DRBs associated with that SRB.

[0169] Alternatively, in other embodiments, the relationship between SRBs and DRBs can be many-to-one. In this case, a group of DRBs may contain one DRB, and control information associated with a group of SRBs can be transmitted through a DRB associated with that group of SRBs.

[0170] Alternatively, in other embodiments, the relationship between SRBs and DRBs can be many-to-many. In this case, a DRB group can contain at least two DRBs, and control information associated with a group of SRBs can be transmitted through at least two DRBs associated with that group of SRBs.

[0171] In Scenario 2, there are multiple ways to configure the association between a set of SRBs and a set of DRBs. This application provides eight possible implementation methods. The following sections will detail these eight possible implementation methods with specific examples.

[0172] The first implementation method of scenario two

[0173] In the first implementation of Scenario 2, the first information may include the bearer identifier corresponding to the SRB and the bearer identifiers corresponding to one or more DRBs associated with the SRB. Alternatively, the first information may include the bearer identifier corresponding to the SRB and the bearer group identifier information corresponding to one or more DRBs associated with the SRB.

[0174] Here, an SRB can be understood as an SRB that is associated with a set of DRBs out of n (n is a positive integer) SRBs configured by the network device for the terminal device. For ease of description, an SRB associated with a set of DRBs can be called a Type I SRB. Each Type I SRB can be associated with one or more DRBs. Or, each Type I SRB can be associated with a set of DRBs. Different Type I SRBs can be associated with the same DRB. Alternatively, different Type I SRBs can be associated with different DRBs. In addition to Type I SRBs, the n SRBs configured by the network device for the terminal device may also include Type II SRBs. Type II SRBs can be understood as SRBs that are not associated with any DRBs.

[0175] In some cases, each of the one or more DRBs associated with a Type 1 SRB may correspond to a bearer identifier. In other cases, one or more DRBs associated with a Type 1 SRB (i.e., a group of DRBs associated with a Type 1 SRB) may correspond to a bearer group identifier.

[0176] In the first implementation of Scenario 2, the association between an SRB and a group of DRBs can be determined by the bearer identifier or bearer group identifier information corresponding to one or more DRBs associated with the SRB.

[0177] To facilitate understanding, the following explanation is provided in conjunction with Table 9. Table 9 shows an example of the first implementation method for Scenario 2.

[0178] Table 9 Example of the first implementation method for Scenario 2

[0179] In Table 9, the network device configures n (n is a positive integer) SRBs for the terminal device, some of which are associated with a group of DRBs. For ease of description, SRBs associated with a group of DRBs are called Type 1 SRBs, and SRBs not associated with any DRBs are called Type 2 SRBs. When configuring any SRB belonging to Type 1 SRBs, the SRB-related configuration parameters include the bearer identifier information corresponding to the SRB, the fifth information, and other configuration parameters related to the SRB. The fifth information includes the bearer identifier information corresponding to one or more DRBs associated with the SRB, or the bearer group identifier corresponding to a group of DRBs associated with the SRB. When configuring any SRB belonging to Type 2 SRBs, the SRB-related configuration parameters include the bearer identifier information corresponding to the SRB and other configuration parameters related to the SRB. The other configuration parameters related to the SRB include at least the protocol layer configuration for implementing the SRB. In Table 9, different SRBs belonging to Type 1 SRBs may be associated with the same or different DRBs.

[0180] The configuration in Table 9 clearly shows which DRBs each SRB belonging to the first type of SRB is associated with (the association between the two is determined by the bearer identifier or bearer group identifier corresponding to one or more DRBs associated with the SRB), but the configuration parameters related to one or more DRBs associated with an SRB are not given in Table 9.

[0181] In the first implementation of Scenario 2, the first information may also include DRB-related configuration parameters. In this first implementation, the DRB-related configuration parameters can include two cases. In the first case, the first information may also include one or more DRB-related configuration parameters associated with the SRB. In the second case, the first information may also include one or more sets of DRB-related configuration parameters and bearer group identifier information corresponding to the fourth target group DRB. These two cases will be explained below with reference to Tables 10A and 10B.

[0182] In the first scenario, the first information may further include one or more DRB-related configuration parameters associated with the SRB. These DRB-related configuration parameters may include the bearer identifier corresponding to the DRB and the protocol layer configuration for implementing the DRB. Alternatively, the DRB-related configuration parameters may include the bearer identifier corresponding to the DRB, the bearer group identifier corresponding to the DRB, and the protocol layer configuration for implementing the DRB.

[0183] The bearer group identifier information corresponding to a DRB can be used to associate a group of DRBs together. In other words, one or more DRBs associated with the same bearer group identifier can be referred to as the same group of DRBs.

[0184] In the first case, the association between an SRB and a group of DRBs can be achieved through the bearer identifiers of one or more DRBs or the bearer group identifier information corresponding to a group of DRBs.

[0185] For ease of understanding, the following explanation is provided in conjunction with Table 10A. Table 10A shows Example 1 of the DRB-related configuration parameters in the first implementation method of Scenario 1 (corresponding to the first case).

[0186] Example 1 of DRB-related configuration parameters in the first implementation method of Scenario 2, Table 10A

[0187] In Table 10A, the network device configures m (m is a positive integer) DRBs for the terminal device. The configuration parameters related to the DRBs include the bearer identifier information corresponding to the DRB and other configuration parameters related to that DRB. Alternatively, the configuration parameters related to the DRBs include the bearer identifier information corresponding to the DRB, the bearer group identifier information corresponding to the DRB, and other configuration parameters related to that DRB. The bearer group identifier information corresponding to the DRB is used to associate a group of DRBs together; that is, one or more DRBs associated with the same bearer group identifier are referred to as the same group of DRBs. Other configuration parameters related to the DRBs include at least the protocol layer configuration for implementing the DRB. In the example shown in Table 10A, the association between an SRB and a group of DRBs is achieved through one or more bearer identifier information or bearer group identifier information corresponding to the DRB.

[0188] The above, with reference to Figure 10A, describes the first scenario of the DRB-related configuration parameters in the first implementation method of Scenario 2. The following, with reference to Figure 10B, describes the second scenario of the DRB-related configuration parameters in the first implementation method of Scenario 2.

[0189] In the second scenario, the first information may further include one or more sets of DRB-related configuration parameters, as well as bearer group identification information corresponding to the fourth target DRB. Here, the fourth target DRB can be understood as any one of the one or more DRB sets.

[0190] The group or multiple DRBs mentioned here can be understood as a group or multiple DRBs configured by the network device for the terminal device. Each DRB in the group or multiple DRBs can be associated with a bearer group identifier.

[0191] The configuration parameters related to DRB can include the bearer identifier corresponding to the DRB, as well as the protocol layer configuration for implementing the DRB.

[0192] In the second case, the association between an SRB and a group of DRBs is achieved through the bearer group identifier corresponding to a group of DRBs.

[0193] For ease of understanding, the following explanation is provided in conjunction with Table 10B. Table 10B shows Example 2 of the DRB-related configuration parameters in the first implementation method of Scenario 2 (corresponding to the second case).

[0194] Example 2 of DRB-related configuration parameters in the first implementation method of Scenario 2, Table 10B

[0195] In Table 10B, the network device configures k (k is a positive integer) DRBs for the terminal device, and each DRB is associated with a bearer group identifier. Each DRB group includes one or more DRBs, and the configuration parameters related to the DRB include the bearer identifier information corresponding to the DRB and other configuration parameters related to the DRB. These other configuration parameters include at least the protocol layer configuration that implements the DRB. In the example shown in Table 10B, the association between an SRB and a group of DRBs is achieved through the bearer group identifier corresponding to a group of DRBs.

[0196] The configurations in Tables 9 and 10A are associated through the bearer identification information corresponding to one or more DRBs associated with the SRB, while the configurations in Tables 9 and 10B are associated through the bearer group identification information corresponding to one or more DRBs associated with the SRB. In this way, the association between an SRB and a group of DRBs can be determined, allowing the terminal device to clearly know which DRBs can transmit the control information associated with each SRB belonging to the first type of SRB.

[0197] In the first implementation of Scenario 2, the association between SRB-related configurations and DRB-related configurations is achieved with a small number of parameters (the bearer identifier or bearer group identifier corresponding to the DRB), and the protocol-related modifications are minimal.

[0198] The second implementation method of scenario two

[0199] In the second implementation of Scenario 2, the first information may include the bearer identifier corresponding to the DRB, and the bearer identifier corresponding to one or more SRBs associated with the DRB.

[0200] Here, a DRB can be understood as a DRB that is associated with a set of SRBs among the m (m is a positive integer) DRBs configured by the network device for the terminal device. For ease of description, a DRB associated with a set of SRBs can be called a first-class DRB. Each first-class DRB can be associated with one or more SRBs. Or, each first-class DRB can be associated with a set of SRBs. Different DRBs belonging to the first-class DRB can be associated with the same set of SRBs. Alternatively, different DRBs belonging to the first-class DRB can be associated with different sets of SRBs. Among the m DRBs configured by the network device for the terminal device, in addition to the first-class DRBs, there may also be second-class DRBs. Second-class DRBs can be understood as DRBs that are not associated with any SRBs.

[0201] In the second implementation of Scenario 2, the association between a group of SRBs and a group of DRBs can be determined by the bearer identifier corresponding to a group of SRBs associated with the DRB.

[0202] To facilitate understanding, the following explanation is provided in conjunction with Table 11. Table 11 shows an example of the second implementation method for Scenario 2.

[0203] Table 11 Examples of the second implementation method for Scenario 2

[0204] In Table 11, the network device configures m (m is a positive integer) DRBs for the terminal device. Some DRBs are associated with a group of SRBs (i.e., one or more SRBs). For ease of description, a DRB associated with a group of SRBs is called a Type I DRB, and a DRB not associated with any SRBs is called a Type II DRB. When configuring any Type I DRB, the configuration parameters related to the DRB include the bearer identifier information corresponding to the DRB, the sixth information, and other configuration parameters related to the DRB. The sixth information includes the bearer identifier information corresponding to one or more SRBs associated with the DRB associated with the sixth information. When configuring any Type II DRB, the configuration parameters related to the DRB include the bearer identifier information corresponding to the DRB and other configuration parameters related to the DRB. The other configuration parameters related to the DRB include at least the protocol layer configuration for implementing the DRB. In the examples shown in Table 11, different Type I DRBs may be associated with the same or different groups of SRBs.

[0205] The configuration in Table 11 clearly shows which SRB each DRB belonging to the first type of DRB is associated with (the association between the two is determined by the bearer identifier corresponding to the SRB associated with the DRB), but the configuration parameters related to the associated SRB are not given in Table 11.

[0206] In the second implementation of Scenario 2, the configuration parameters of a set of SRB-related parameters associated with DRB can be either not configured for the terminal device or configured for the terminal device.

[0207] Optionally, in some embodiments, the configuration parameters related to the set of SRBs associated with the DRB are not configured for the terminal device. That is, the set of SRBs associated with the DRB is not actually established. Since the protocol already specifies which control information (e.g., RRC messages) can be transmitted through which SRB, after configuring the set of DRBs associated with the corresponding SRB, the terminal device can transmit the control information (e.g., RRC messages) associated with the SRBs of that set of DRBs through that set of DRBs. It is unnecessary to configure the corresponding SRBs simultaneously with configuring the set of DRBs associated with the SRBs, as performing the same data transmission task through two bearers is not an efficient resource utilization method. In this approach, the configuration overhead is small, and resource utilization efficiency is high.

[0208] Optionally, in other embodiments, the configuration parameters of a set of SRBs associated with the DRB can be configured for the terminal device. That is, the set of SRBs associated with the DRB is still actually established. Although this method is not very resource efficient, it allows for parallel transmission of control information (e.g., RRC messages) through another backup radio bearer when congestion occurs. For example, RRC message 1 is transmitted via SRB1, where RRC message 1 is divided into 10 data segments. While the terminal device is still transmitting the fifth data segment of RRC message 1, RRC message 2 carried by SRB1 (e.g., RRC message 2 carries emergency indication information such as overheating alarms on the terminal device side) needs to be urgently sent to the network device. In related technologies, the terminal device needs to wait until all data segments of RRC message 1 are successfully transmitted before it can start transmitting RRC message 2. This RRC message transmission mechanism causes delays in the network device's response to the terminal device's emergency requests, which is detrimental to the user experience. In this scenario, the transmission of RRC message 2, which is likely to experience congestion, via the DRB associated with SRB1 can effectively ensure that RRC message 2 is transmitted to the network device in a timely manner, reducing the waiting time for RRC message 2 in this scenario and optimizing the user experience.

[0209] For ease of understanding, the following explanation is based on Table 12. Table 12 shows an example of SRB-related configuration parameters in the second implementation of Scenario 2. In the example in Table 12, the set of SRBs associated with the DRB is still actually established.

[0210] Table 12 Examples of SRB-related configuration parameters in the second implementation method of Scenario 2.

[0211] In Table 12, the network device configures n (n is a positive integer) SRBs for the terminal device. The configuration parameters related to the SRB include the bearer identification information corresponding to the SRB and other configuration parameters related to the SRB. Among them, the other configuration parameters related to the SRB include at least the protocol layer configuration for implementing the SRB.

[0212] The configurations in Tables 11 and 12 determine the association between a group of SRBs and a group of DRBs by using the bearer identifiers corresponding to a group of SRBs associated with the DRB. This allows the terminal device to clearly know which SRBs' associated control information can be transmitted through which DRBs.

[0213] In the second implementation of Scenario 2, the association between a set of SRBs and a set of DRBs is determined by a small number of parameters (bearer identification information corresponding to SRBs), with minimal changes to the protocol.

[0214] The third implementation method of scenario two

[0215] In the third implementation of Scenario 2, the first information may include one or more sets of DRB-related configuration parameters, and a set of bearer identifiers corresponding to a set of SRBs associated with the fifth target DRB. The fifth target DRB can be understood as any one of the one or more DRBs.

[0216] The group or multiple DRBs can be understood as a group or multiple DRBs configured by the terminal device for the network device. Each DRB in the group or multiple DRBs (i.e., the fifth target group DRB) can be associated with a group of SRBs. In other words, each DRB can be associated with one or more SRBs.

[0217] The configuration parameters related to DRB can include the bearer identifier corresponding to the DRB, as well as the protocol layer configuration for implementing the DRB.

[0218] To facilitate understanding, Table 13 is used as an example below. Table 13 shows an example of the third implementation method for Scenario 2.

[0219] Table 13 Examples of the third implementation method for Scenario 2

[0220] In Table 13, the network device configures k (k is a positive integer) DRBs for the terminal device. Each DRB group includes one or more DRBs. Each DRB group is associated with a set of SRBs. Each SRB group includes one or more SRBs. The configuration parameters related to the DRBs include the bearer identification information corresponding to the DRB and other configuration parameters related to the DRB. Among them, the other configuration parameters related to the DRBs include at least the protocol layer configuration for implementing the DRB.

[0221] The configuration in Table 13 clearly shows which set of SRBs a set of DRBs is associated with (the association between the two is determined by the bearer identifiers of the SRBs associated with the DRBs), but the configuration parameters related to the SRBs associated with the DRBs are not given in Table 13.

[0222] In the third implementation of Scenario 2, the configuration parameters of a set of SRBs associated with a set of DRBs may or may not be configured for the terminal device.

[0223] Optionally, in some embodiments, the configuration parameters related to a set of SRBs associated with a set of DRBs may not be configured for the terminal device. That is, the set of SRBs associated with a set of DRBs is not actually established.

[0224] Optionally, in other embodiments, a set of SRB-related configuration parameters associated with a set of DRBs can be configured for the terminal device. That is, a set of SRBs associated with a set of DRBs is still actually established. The configuration parameters related to SRBs can be found in Table 12, and will not be repeated here.

[0225] In the third implementation of Scenario 2, the association between a set of SRBs and a set of DRBs is determined by the bearer identification information corresponding to a set of SRBs associated with a set of DRBs. The terminal device can then clearly know which set of SRBs is associated with which set of DRBs to transmit control information.

[0226] In the third implementation of Scenario 2, on the one hand, the association between a group of SRBs and a group of DRBs is determined by a small number of parameters (the bearer identifier corresponding to the SRB). On the other hand, configuring DRBs by group saves more configuration overhead.

[0227] The fourth implementation method of scenario two

[0228] In the fourth implementation of Scenario 2, the first information may include one or more sets of SRB-related configuration parameters, as well as a bearer identifier or bearer group identifier corresponding to a set of DRBs associated with the first target group SRB. Here, the first target group SRB can be understood as any one of the one or more sets of SRBs.

[0229] The "one or more SRBs" mentioned here can be understood as one or more SRBs configured by the network device for the terminal device. Each SRB in the one or more SRBs (i.e., the first target SRB) can be associated with a DRB. Or, each SRB in the one or more SRBs (i.e., the first target SRB) can be associated with one or more DRBs.

[0230] SRB-related configuration parameters may include the bearer identifier corresponding to the SRB, as well as the protocol layer configuration for implementing the SRB.

[0231] In the fourth implementation of Scenario 2, the association between a set of SRBs and a set of DRBs can be determined by the bearer identifier or bearer group identifier corresponding to a set of DRBs associated with a set of SRBs.

[0232] To facilitate understanding, the following explanation is provided in conjunction with Table 14. Table 14 shows an example of the fourth implementation method for Scenario 2.

[0233] Table 14 Examples of the fourth implementation method in Scenario 2

[0234] In Table 14, the network device configures k (k is a positive integer) groups of SRBs for the terminal device. Each group of SRBs includes one or more SRBs. Each group of SRBs is associated with a group of DRBs. Each group of DRBs includes one or more DRBs. The configuration parameters related to SRBs include the bearer identification information corresponding to the SRB and other configuration parameters related to the SRB. Among them, the other configuration parameters related to the SRB include at least the protocol layer configuration for implementing the SRB.

[0235] The configuration in Table 14 clearly shows which DRB a group of SRBs is associated with (the association between the two is determined by the bearer identifier or bearer group identifier corresponding to the DRBs associated with the group of SRBs), but the configuration parameters related to the associated DRBs are not given in Table 14.

[0236] In the fourth implementation of Scenario 2, the first information may also include DRB-related configuration parameters. The DRB-related configuration parameters can be found in Tables 10A and 10B, and will not be repeated here.

[0237] The configurations in Tables 14 and 10A determine the association between a group of SRBs and a group of DRBs by using the bearer identifiers corresponding to the group of DRBs associated with the group of SRBs. The configurations in Tables 14 and 10B determine the association between a group of SRBs and a group of DRBs by using the bearer group identifiers corresponding to the group of DRBs associated with the group of SRBs. In this way, the terminal device can clearly know which group of SRBs' associated control information can be transmitted through which group of DRBs.

[0238] In the fourth implementation of Scenario 2, on the one hand, the association between SRB-related configurations and DRB-related configurations is achieved with a small number of parameters (the bearer identifier or bearer group identifier corresponding to the DRB). On the other hand, configuring SRBs by group saves more configuration overhead.

[0239] The fifth implementation method of scenario two

[0240] In the fifth implementation of scenario two, the first information may include one or more second parameters.

[0241] The second parameter can be used to indicate a set of DRB-related configuration parameters. In other words, the second parameter can be used to configure a set of DRBs. A network device can configure k (k is a positive integer) DRBs for a terminal device. These k DRBs can be configured sequentially using k second parameters.

[0242] The set of DRBs indicated by the second parameter (or the set of DRBs configured by the second parameter) can be used to transmit control information associated with a set of SRBs determined based on predefined protocol information. This set of SRBs can be called an SRB group. An SRB group can include one or more SRBs. Different SRB groups can correspond to different SRB types. Different second parameters can be associated with different SRB groups. Or, different second parameters can be associated with different SRB types.

[0243] The SRB type associated with the second parameter can be determined based on protocol predefined information. Alternatively, the SRB type associated with the second parameter can be determined using the protocol's default method. The protocol predefined information may include the predefined location of the second parameter within the protocol. In other words, the predefined location of the second parameter within the protocol can determine which set of SRBs the DRB configured for transmits the associated control information.

[0244] The configuration parameters related to DRB can include the bearer identifier corresponding to the DRB, as well as the protocol layer configuration for implementing the DRB.

[0245] To facilitate understanding, the following explanation is provided in conjunction with Table 15. Table 15 shows an example of the fifth implementation method for Scenario 2.

[0246] Table 15 Example of the fifth implementation method for Scenario 2

[0247] In Table 15, the network device configures k (k is a positive integer) DRBs for the terminal device. Each DRB group includes one or more DRBs. The k DRBs are configured sequentially through parameters one through parameter k. The target DRB in the k DRB groups is used to transmit control information associated with a specific SRB, and the target DRB can be any one of the k DRB groups. Parameter k includes configuration parameters related to the k-th DRB. The configuration parameters related to the DRB include the bearer identifier corresponding to the DRB and the protocol layer configuration for implementing the DRB. Different second parameters are associated with different SRB types.

[0248] In the example shown in Table 15, the protocol stipulates that parameter one is associated with SRB1, that is, a set of DRBs configured by parameter one is used to transmit control information associated with SRB1; the protocol stipulates that parameter two is associated with SRB2 and SRB4, that is, a set of DRBs configured by parameter two is used to transmit control information associated with SRB2 and SRB4; the protocol stipulates that parameter k is associated with SRBk, that is, a set of DRBs configured by parameter k is used to transmit control information associated with SRBk.

[0249] In the fifth implementation of Scenario 2, a set of SRB-related configuration parameters associated with a set of DRBs can be configured either not to be configured for the terminal device or can be configured for the terminal device.

[0250] Optionally, in some embodiments, the configuration parameters related to a set of SRBs associated with a set of DRBs may not be configured for the terminal device. That is, the set of SRBs associated with the DRBs is not actually established.

[0251] Optionally, in some embodiments, a set of SRB-related configuration parameters associated with a set of DRBs can be configured for the terminal device. That is, the set of SRBs associated with the DRBs is still actually established. The configuration parameters related to the SRBs can be found in Table 12, and will not be repeated here.

[0252] In the fifth implementation method of Scenario 2, the overhead of configuration can be saved, and there is no need to update the SRB-related configuration parameters.

[0253] The sixth implementation method of scenario two

[0254] The sixth implementation of Scenario 2 can include two scenarios. In the first scenario, the first information may include the bearer identifier corresponding to the DRB, and one or more second indication information associated with the DRB. In the second scenario, the first information may include one or more sets of DRB-related configuration parameters, and one or more second indication information associated with the sixth target group DRB. These two scenarios will be described in detail below with reference to Tables 16A and 16B.

[0255] In the first scenario, the first information may include the bearer identifier corresponding to the DRB, and one or more second indication information associated with the DRB. The second indication information may be used to indicate an SRB type associated with the DRB.

[0256] Here, a DRB can be understood as: among the m (m is a positive integer) DRBs configured by the network device for the terminal device, the DRB associated with a set of SRBs. For ease of description, a DRB associated with a set of SRBs can be called a first-type DRB. Each first-type DRB can be associated with a set of SRBs. Or, each first-type DRB can be associated with one or more SRBs. Each DRB belonging to the first-type DRB can be associated with the same one or more SRB types. Alternatively, each DRB belonging to the first-type DRB can be associated with different one or more SRB types. Among the m DRBs configured by the network device for the terminal device, in addition to the first-type DRBs, there may also be second-type DRBs. Second-type DRBs can be understood as DRBs that are not associated with any SRBs.

[0257] Each DRB belonging to the first type of DRB can be associated with one or more second indication information. Each of the one or more second indication information can be used to indicate an SRB associated with a DRB associated with the one or more second indication information. Therefore, one or more SRBs associated with the DRB can be indicated through the one or more second indication information.

[0258] In the first case, the association between a set of DRBs and a set of SRBs can be determined through the second indication information associated with a set of DRBs.

[0259] For ease of understanding, the following explanation is provided in conjunction with Table 16A. Table 16A shows Example 1 of the sixth implementation method for Scenario 2 (corresponding to the first case of the sixth implementation method for Scenario 2).

[0260] Table 16A Example 1 of the sixth implementation method for Scenario 2

[0261] In Table 16A, the network device configures m (m is a positive integer) DRBs for the terminal device. Some DRBs are associated with a group of SRBs. For ease of description, DRBs associated with a group of SRBs are called Type 1 DRBs, and DRBs not associated with any SRBs are called Type 2 DRBs. When configuring any Type 1 DRB, the configuration parameters related to the DRB include the bearer identifier information corresponding to the DRB, one or more second indication information, and other configuration parameters related to the DRB. The second indication information is used to indicate the type of SRB associated with the DRB. When configuring any Type 2 DRB, the configuration parameters related to the DRB include the bearer identifier information corresponding to the DRB and other configuration parameters related to the DRB. These other configuration parameters include the protocol layer configuration for implementing the DRB.

[0262] The first scenario of the sixth implementation method for Scenario 2 has been described above with reference to Table 16A. The second scenario of the sixth implementation method for Scenario 2 will now be described below with reference to Table 16B.

[0263] In the second scenario, the first information may include one or more sets of DRB-related configuration parameters, as well as one or more second indication information associated with the sixth target group DRB. Here, the sixth target group DRB can be understood as any one of the one or more DRB sets.

[0264] The group or multiple DRBs mentioned here can be understood as a group or multiple DRBs configured by the network device for the terminal device. Each DRB in the group or multiple DRBs (i.e., the sixth target group DRB) can be associated with one or more second indication information. Each of the one or more second indication information can be used to indicate a type of SRB associated with the group of DRBs associated with the one or more second indication information. Therefore, the one or more second indication information can be used to indicate the type of a group of SRBs associated with the group of DRBs associated with the one or more second indication information.

[0265] The configuration parameters related to the DRB can include the bearer identifier information corresponding to the DRB, as well as other configuration parameters related to the DRB. These other configuration parameters can include the protocol layer configuration for implementing the DRB.

[0266] In the second case, the association between a set of DRBs and a set of SRBs can be determined through the second indication information associated with a set of DRBs.

[0267] For ease of understanding, the following explanation is provided in conjunction with Table 16B. Table 16B shows Example 2 of the sixth implementation method for Scenario 2 (corresponding to the second case of the sixth implementation method for Scenario 2).

[0268] Example 2 of the sixth implementation method in Scenario 2 of Table 16B

[0269] In Table 16B, the network device configures k (k is a positive integer) DRBs for the terminal device. Each DRB is associated with a set of SRBs through one or more second indication information. Each DRB includes one or more DRBs, and the configuration parameters related to the DRB include the bearer identification information corresponding to the DRB and other configuration parameters related to the DRB. Among them, the other configuration parameters related to the DRB include the protocol layer configuration for implementing the DRB.

[0270] The first and second cases of the sixth implementation method in Scenario 1 both involve the second instruction information.

[0271] Optionally, in some embodiments, the second indication information can be an identification information (e.g., an ID identifier). The identification information can be understood as information different from the information carrying the identification. Different values ​​of the identification information can correspond to different types of SRBs. For example, a value of '000' corresponds to SRB1, a value of '001' corresponds to SRB2, a value of '010' corresponds to SRB3, a value of '011' corresponds to SRB4, a value of '100' corresponds to SRB5, and so on.

[0272] Alternatively, in other embodiments, the second indication information can be implemented using the choice{} function. Each value of the choice{} function can correspond to a different type of SRB.

[0273] Alternatively, in other embodiments, the second indication information can be implemented using enumeration parameters. Each element of the enumeration parameters can correspond to a type of SRB.

[0274] The configuration in Table 16A or Table 16B clearly shows which set of SRBs a set of DRBs is associated with (the association between the two is determined by the second indication information associated with a set of DRBs), but the configuration parameters related to the set of SRBs associated with a set of DRBs are not given in Table 16A or Table 16B.

[0275] In the sixth implementation of Scenario 2, a set of SRB-related configuration parameters associated with a set of DRBs may or may not be configured for the terminal device.

[0276] Optionally, in some embodiments, the configuration parameters related to a set of SRBs associated with a set of DRBs may not be configured for the terminal device. That is, the set of SRBs associated with the DRBs is not actually established.

[0277] Optionally, in some embodiments, a set of SRB-related configuration parameters associated with a set of DRBs can be configured for the terminal device. That is, the set of SRBs associated with the DRBs is still actually established. The configuration parameters related to the SRBs can be found in Table 12, and will not be repeated here.

[0278] In the sixth implementation of Scenario 2 (including the first and second cases), the association between a set of SRBs and a set of DRBs is determined by the second indication information associated with a set of DRBs. The terminal device can then clearly know which set of SRBs is associated with which DRBs to transmit control information.

[0279] The sixth implementation method in Scenario 2 balances the flexibility of configuration with the size of overhead, and does not require updating SRB-related configuration parameters.

[0280] The seventh implementation method of scenario two

[0281] The seventh implementation of Scenario 2 can include two scenarios. In the first scenario, the first information can include the bearer identifier corresponding to the DRB and the first bit string information associated with that DRB. In the second scenario, the first information can include one or more sets of DRB-related configuration parameters and the first bit string information associated with the seventh target group DRB. These two scenarios will be described in detail below with reference to Tables 17A and 17B.

[0282] In the first case, the first information may include the bearer identifier corresponding to the DRB, and the first bit string information associated with the DRB. This first bit string information may be used to indicate the type of one or more SRBs associated with the DRB.

[0283] Here, a DRB can be understood as: among the m (m is a positive integer) DRBs configured by the network device for the terminal device, the DRB associated with a set of SRBs. For ease of description, a DRB associated with a set of SRBs can be called a first-type DRB. Each DRB belonging to the first-type DRB can be associated with a set of SRBs. Or, each DRB belonging to the first-type DRB can be associated with one or more SRBs. The types of one or more SRBs associated with each DRB belonging to the first-type DRB can be the same. Alternatively, the types of one or more SRBs associated with each DRB belonging to the first-type DRB can also be different. Among the m DRBs configured by the network device for the terminal device, in addition to the first-type DRBs, a second-type DRB may also be included. A second-type DRB can be understood as a DRB that is not associated with any SRBs.

[0284] Each DRB belonging to the first type of DRB can be associated with a first bit string. The target bit in the first bit string can be associated with an SRB of a certain type. Here, the target bit can be understood as any single bit in the first bit string. The first bit string can contain one or more target bits. For example, if the first bit string contains 5 bits, the first bit is associated with SRB1, the second with SRB2, the third with SRB3, the fourth with SRB4, and the fifth with SRB5.

[0285] If the target bit in the first bit string information has a first value, then a DRB associated with the first bit string information can be used to transmit control information associated with the SRB associated with the target bit. For example, if the target bit in the first bit string information has a value of '1', then the DRB associated with the first bit string information can be used to transmit control information associated with the SRB associated with the target bit.

[0286] The association between the target bit and the SRB type can be determined based on predefined protocol information. Alternatively, the association between the target bit and the SRB type can be determined based on the protocol's default method.

[0287] In the first case, the association between a set of DRBs and a set of SRBs can be determined by the first bit string information associated with a set of DRBs.

[0288] For ease of understanding, the following explanation is provided in conjunction with Table 17A. Table 17A shows Example 1 of the seventh implementation method for Scenario 2 (corresponding to the first case of the seventh implementation method for Scenario 2).

[0289] Example 1 of the seventh implementation method in Scenario 2 of Table 17A

[0290] In Table 17A, the network device configures m (m is a positive integer) DRBs for the terminal device. Some DRBs are associated with a group of SRBs. For ease of description, a DRB associated with a group of SRBs is called a Type I DRB, and a DRB not associated with any SRBs is called a Type II DRB. When configuring any DRB belonging to Type I DRBs, the configuration parameters related to the DRB include the bearer identifier information corresponding to the DRB, the first bit string information, and other configuration parameters related to the DRB. Each bit in the first bit string information is associated with a type of SRB, and this association is determined by protocol agreement. For example, if the first bit string information consists of 5 bits, the protocol stipulates that the first bit is associated with SRB1, the second bit with SRB2, the third bit with SRB3, the fourth bit with SRB4, and the fifth bit with SRB5. If the target bit is a first value (e.g., '1'), then the DRB associated with the first bit string information is considered to be used to transmit control information associated with the SRB associated with that target bit, where the target bit is any bit in the first bit string information. When configuring any DRB belonging to the second type of DRB, the DRB-related configuration parameters include the bearer identifier information corresponding to the DRB and other configuration parameters related to that DRB. These other configuration parameters include the protocol layer configuration for implementing the DRB. In the example in Table 17A, the types of one or more SRBs associated with each DRB belonging to the first type of DRB can be the same or different.

[0291] The first scenario of the seventh implementation method for Scenario 2 has been introduced above with reference to Table 17A. The second scenario of the seventh implementation method for Scenario 2 will be introduced below with reference to Table 17B.

[0292] In the second scenario, the first information may include one or more sets of DRB-related configuration parameters and a first bit string associated with the seventh target group DRB. The seventh target group DRB can be understood as any one of these one or more DRB sets.

[0293] The group or multiple DRBs here can be understood as DRBs associated with a set of SRBs among the k (k is a positive integer) DRBs configured by the network device for the terminal device. For ease of description, the DRBs associated with a set of SRBs among the k (k is a positive integer) DRBs configured by the network device for the terminal device are called Type I DRBs. Each Type I DRB can be associated with a set of SRBs. Or, each Type I DRB can be associated with one or more SRBs. In addition to Type I DRBs, the k DRBs configured by the network device for the terminal device may also include Type II DRBs. Type II DRBs can be understood as DRBs that are not associated with any SRBs.

[0294] Each group of first-class DRBs (i.e., the seventh target group DRBs) can be associated with a first bit string. The target bits in the first bit string can be associated with one type of SRB. The first bit string can be used to indicate the type of one or more SRBs associated with the group of DRBs associated with it. Here, the target bit can be understood as any single bit in the first bit string. The first bit string can contain one or more target bits. For example, if the first bit string contains 5 bits, the first bit is associated with SRB1, the second bit with SRB2, the third bit with SRB3, the fourth bit with SRB4, and the fifth bit with SRB5.

[0295] If the target bit in the first bit string information has a first value, then a set of DRBs associated with the first bit string information can be used to transmit control information associated with the SRB associated with the target bit. For example, if the target bit in the first bit string information has a value of '1', then a set of DRBs associated with the first bit string information can be used to transmit control information associated with the SRB associated with the target bit.

[0296] The association between the target bit and the SRB type can be determined based on predefined protocol information. Alternatively, the association between the target bit and the SRB type can be determined based on the protocol's default method.

[0297] DRB-related configuration parameters can include the bearer identifier corresponding to the DRB. DRB-related configuration parameters can also include the protocol layer configuration for implementing the DRB.

[0298] In the second case, the association between a set of DRBs and a set of SRBs can be determined by the first bit string information associated with a set of DRBs.

[0299] For ease of understanding, the following explanation is provided in conjunction with Table 17B. Table 17B shows Example 2 of the seventh implementation method for Scenario 2 (corresponding to the second case of the seventh implementation method for Scenario 2).

[0300] Example 2 of the seventh implementation method in Scenario 2 of Table 17B

[0301] In Table 17B, the network device configures k (k is a positive integer) DRBs for the terminal device. Some DRBs are associated with a set of SRBs. For ease of description, a DRB associated with a set of SRBs is called a Type I DRB, and a DRB not associated with any SRB is called a Type II DRB. When configuring any DRB belonging to Type I DRBs, the configuration includes the configuration parameters related to that DRB and the first bit string information. The configuration parameters related to the DRB include the bearer identifier information corresponding to the DRB and other configuration parameters related to the DRB. Each bit in the first bit string information is associated with a type of SRB, and this association is determined by protocol agreement. For example, if the first bit string information consists of 5 bits, the protocol stipulates that the first bit is associated with SRB1, the second bit with SRB2, the third bit with SRB3, the fourth bit with SRB4, and the fifth bit with SRB5. If the target bit is a first value (e.g., '1'), then the DRB associated with the first bit string information is considered to be used to transmit control information associated with the SRB associated with the target bit, where the target bit is any bit in the first bit string information. When configuring any DRB belonging to the second type of DRB, the DRB-related configuration parameters include the bearer identifier information corresponding to the DRB and other configuration parameters related to the DRB. These other configuration parameters include the protocol layer configuration for implementing the DRB.

[0302] The configuration in Table 17A or Table 17B clearly shows which set of SRBs a set of DRBs is associated with (the association between the two is determined by the first bit string information associated with a set of DRBs), but the configuration parameters related to the set of SRBs associated with a set of DRBs are not given in Table 17A or Table 17B.

[0303] In the seventh implementation of Scenario 2, a set of SRB-related configuration parameters associated with a set of DRBs may or may not be configured for the terminal device.

[0304] Optionally, in some embodiments, configuration parameters related to a set of SRBs associated with a set of DRBs can be configured for the terminal device. That is, the set of SRBs associated with the DRBs is not actually established.

[0305] Optionally, in some embodiments, a set of SRB-related configuration parameters associated with a set of DRBs can be configured for the terminal device. That is, the set of SRBs associated with the DRBs is still actually established. The configuration parameters related to the SRBs can be found in Table 12, and will not be repeated here.

[0306] In the seventh implementation of Scenario 2 (including the first and second cases), the association between a set of SRBs and a set of DRBs is determined by the first bit string information associated with a set of DRBs. The terminal device can then clearly know which set of SRBs is associated with which DRBs to transmit control information.

[0307] Since the number of target bits included in the first bit string information associated with each DRB belonging to the first type of DRB can be one or more, the association between one or more SRBs and one or a group of DRBs can be indicated by one or more target bits.

[0308] The seventh implementation method in Scenario 2 balances the flexibility of configuration with the size of overhead, and does not require updating SRB-related configuration parameters.

[0309] The eighth implementation method of scenario two

[0310] The eighth implementation of Scenario 2 can include two scenarios. In the first scenario, the first information may include the bearer identifier corresponding to the DRB, and one or more third indication information associated with the DRB. In the second scenario, the first information may include one or more sets of DRB-related configuration parameters, and one or more third indication information associated with the eighth target group DRB. These two scenarios will be described in detail below with reference to Tables 18A and 18B.

[0311] In the first scenario, the first information may include the bearer identifier corresponding to the DRB, and one or more third indication information associated with the DRB. This third indication information may be associated with an SRB type. Alternatively, the third indication information may be associated with a type of SRB.

[0312] Here, a DRB can be understood as: among the m (m is a positive integer) DRBs configured by the network device for the terminal device, the DRB associated with a set of SRBs. For ease of description, a DRB associated with a set of SRBs can be called a first-type DRB. Each first-type DRB can be associated with a set of SRBs. Or, each first-type DRB can be associated with one or more SRBs. Each DRB belonging to the first-type DRB can be associated with the same one or more SRB types. Alternatively, each DRB belonging to the first-type DRB can be associated with different one or more SRB types. Among the m DRBs configured by the network device for the terminal device, in addition to the first-type DRBs, there may also be second-type DRBs. Second-type DRBs can be understood as DRBs that are not associated with any SRBs.

[0313] Each first-class DRB can be associated with one or more third-class indications. Any one of these third-class indications can be associated with an SRB type. For example, a DRB may be associated with five third-class indications: the first third-class indication is associated with SRB1, the second with SRB2, the third with SRB3, the fourth with SRB4, and the fifth with SRB5.

[0314] In one or more third indication messages associated with a DRB, if any third indication message takes the value of a second value, it can indicate that the DRB is used to transmit control information associated with the SRB associated with that third indication message. For example, in one or more third indication messages associated with a DRB, if any third indication message takes the value of 'true', it indicates that the DRB is used to transmit control information associated with the SRB associated with that third indication message.

[0315] The association between the third instruction information and the SRB type can be determined based on predefined information in the protocol. Alternatively, the association between the third instruction information and the SRB type can be determined based on the protocol's default method.

[0316] In the first case, the association between a set of DRBs and a set of SRBs can be determined by one or more third indication information associated with a set of DRBs.

[0317] For ease of understanding, the following explanation is provided in conjunction with Table 18A. Table 18A shows Example 1 of the eighth implementation method for Scenario 2 (corresponding to the first case of the eighth implementation method for Scenario 2).

[0318] Example 1 of the eighth implementation method in Scenario 2 of Table 18A

[0319] In Table 18A, the network device configures m (m is a positive integer) DRBs for the terminal device. Some DRBs are associated with a group of SRBs. For ease of description, a DRB associated with a group of SRBs is called a Type I DRB, and a DRB not associated with any SRBs is called a Type II DRB. When configuring any DRB belonging to Type I DRBs, the configuration parameters related to the DRB include the bearer identification information corresponding to the DRB, one or more third indication information, and other configuration parameters related to the DRB. Each third indication information is associated with a type of SRB, and this association is determined by protocol agreement. For example, if a DRB is associated with five third indication information, the protocol stipulates that the first third indication information is associated with SRB1, the second with SRB2, the third with SRB3, the fourth with SRB4, and the fifth with SRB5. If the value of the corresponding third indication information is the second value (e.g., 'true'), then the DRB associated with that third indication information is considered to be used to transmit the control information associated with the SRB associated with that third indication information. When configuring any DRB belonging to the second type of DRB, the DRB-related configuration parameters include the bearer identifier information corresponding to the DRB and other configuration parameters related to the DRB. These other configuration parameters include at least the protocol layer configuration that implements the DRB. In the example shown in Table 18A, each DRB belonging to the first type of DRB may be associated with one or more SRB types that are the same or different.

[0320] The first scenario of the eighth implementation method for Scenario 2 has been introduced above with reference to Table 18A. The second scenario of the eighth implementation method for Scenario 2 will be introduced below with reference to Table 18B.

[0321] In the second scenario, the first information may include one or more sets of DRB-related configuration parameters, as well as one or more third indication information associated with the eighth target group DRB. The eighth target group DRB can be understood as any one of the one or more DRB sets.

[0322] The group or multiple DRBs can be understood as DRBs associated with a set of SRBs among the k (k is a positive integer) DRBs configured by the network device for the terminal device. For ease of description, the DRBs associated with a set of SRBs among the k (k is a positive integer) DRBs configured by the network device for the terminal device are called Type I DRBs. Each Type I DRB can be associated with a set of SRBs. Or, each Type I DRB can be associated with one or more SRBs. In addition to Type I DRBs, the k DRBs configured by the network device for the terminal device may also include Type II DRBs. Type II DRBs can be understood as DRBs that are not associated with any SRBs.

[0323] Each group of first-class DRBs (i.e., the eighth target group DRB) can be associated with one or more third indication messages. Any one of these third indication messages can be associated with an SRB type. For example, a group of DRBs may be associated with five third indication messages: the first third indication message is associated with SRB1, the second with SRB2, the third with SRB3, the fourth with SRB4, and the fifth with SRB5.

[0324] In a set of DRBs associated with one or more third indication messages, if any one of the third indication messages takes the value of a second value, it can indicate that the set of DRBs is used to transmit control information associated with the SRB associated with that third indication message. For example, in a set of DRBs associated with one or more third indication messages, if any one of the third indication messages takes the value of 'true', it indicates that the set of DRBs is used to transmit control information associated with the SRB associated with that third indication message.

[0325] The association between the third instruction information and the SRB type can be determined based on predefined information in the protocol. Alternatively, the association between the third instruction information and the SRB type can be determined based on the protocol's default method.

[0326] DRB-related configuration parameters can include the bearer identifier corresponding to the DRB. DRB-related configuration parameters can also include the protocol layer configuration for implementing the DRB.

[0327] In the second case, the association between a set of DRBs and a set of SRBs can be determined by one or more third indication information associated with a set of DRBs.

[0328] For ease of understanding, the following explanation is provided in conjunction with Table 18B. Table 18B shows Example 2 of the eighth implementation method for Scenario 2 (corresponding to the second case of the eighth implementation method for Scenario 2).

[0329] Example 2 of the eighth implementation method in Scenario 2 of Table 18B

[0330] In Table 18B, the network device configures k (k is a positive integer) DRBs for the terminal device. Some DRBs are associated with a set of SRBs. For ease of description, a DRB associated with a set of SRBs is called a Type I DRB, and a DRB not associated with any SRB is called a Type II DRB. When configuring any DRB belonging to Type I DRBs, the configuration includes configuration parameters related to that DRB and one or more third indication information. The configuration parameters related to the DRB include the bearer identifier information corresponding to the DRB and other configuration parameters related to the DRB. Each third indication information is associated with a type of SRB, and this association is determined by protocol agreement. For example, if a DRB is associated with five third indication information, the protocol stipulates that the first third indication information is associated with SRB1, the second with SRB2, the third with SRB3, the fourth with SRB4, and the fifth with SRB5. If the value of the corresponding third indication information is the second value (e.g., 'true'), then the DRB associated with the third indication information is considered to be used to transmit the control information associated with the SRB associated with the third indication information. When configuring any DRB belonging to the second type of DRB, the DRB-related configuration parameters include the bearer identification information corresponding to the DRB and other configuration parameters related to the DRB. Among them, the other configuration parameters related to the DRB include the protocol layer configuration for implementing the DRB.

[0331] The configuration in Table 18A or Table 18B can clearly identify which group of SRBs a group of DRBs is associated with (the association between the two is determined by one or more third indication information associated with a group of DRBs), but the configuration parameters related to the group of SRBs associated with a group of DRBs are not given in Table 18A or Table 18B.

[0332] In the eighth implementation of Scenario 2, a set of SRB-related configuration parameters associated with a set of DRBs may or may not be configured for the terminal device.

[0333] Optionally, in some embodiments, the configuration parameters related to a set of SRBs associated with a set of DRBs may not be configured for the terminal device. That is, the set of SRBs associated with the DRBs is not actually established.

[0334] Optionally, in some embodiments, a set of SRB-related configuration parameters associated with a set of DRBs can be configured for the terminal device. That is, the set of SRBs associated with the DRBs is still actually established. The configuration parameters related to the SRBs can be found in Table 12, and will not be repeated here.

[0335] In the eighth implementation of Scenario 2 (including the first and second cases), the third indication information associated with each or each group of DRBs belonging to the first type of DRB can be one or more. Therefore, one or more third indication information can indicate the association relationship between one or more SRBs and one or a group of DRBs.

[0336] The eighth implementation method in Scenario 2 balances the flexibility of configuration with the size of overhead, and does not require updating SRB-related configuration parameters.

[0337] The above provides a detailed description of the six implementation methods for scenario one and the eight implementation methods for scenario two provided in the embodiments of this application, using specific examples.

[0338] As can be seen from the above description, the embodiments of this application establish an association between a set of DRBs and one or more SRBs, enabling the transmission of control information associated with one or more SRBs using a set of DRBs. On one hand, this method provides an alternative data transmission channel for the control information (or data) transmitted by the SRB. In this way, when signaling transmission congestion occurs in the SRB, data transmission can be switched to another data transmission channel (i.e., the DRB) to complete the data transmission, thereby alleviating the situation where data transmission is delayed due to SRB signaling transmission congestion. On the other hand, it can reduce or avoid SRB congestion caused by excessively large amounts of data transmitted by the SRB. In related technologies, SRBs use serial transmission technology. For example, a new RRC message transmission is not allowed until all segments of an RRC message have been successfully transmitted. As a result, if there is a large amount of RRC content to be transmitted, it will lead to too many RRC message segments to be transmitted, and these excessive RRC message segments will block subsequent RRC message transmissions before successful transmission. Transmitting larger RRC messages through the DRB can effectively avoid SRB congestion.

The apparatus embodiments of this application will be described in detail below with reference to Figures 3 to 5.
