Description

Technical Field

[0001] This application relates to the field of wireless communication, and in particular to an information transmission method, apparatus, related equipment and storage medium. Background Technology

[0002] In the 6G protocol stack, the AI ​​Plane and Data Plane are introduced. These two planes are integrated into the Control Plane and User Plane of the protocol stack, providing the protocol stack functions required by the User Equipment (UE) and its service transmission, thus achieving a flexible network. Flexibility refers to configuring different protocol stack functions according to user needs (such as Quality of Service (QoS) requirements, service type requirements, and slice types), and providing these functions to users as "services." The internal functions of these "services" can be defined by the receiving and sending ends according to their own implementations, such as AI-related models or algorithms, and data plane processing.

[0003] Providing protocol stack functions to users as "services" refers to Service Oriented Function (SOF) of the protocol stack. In other words, the flexibility of the 6G protocol stack (such as on-demand function selection, unified protocol data unit (PDU) format with low redundancy overhead, connectionless or lightweight connection between protocol layers, and on-demand application of protocol functions as services) requires a departure from the 5G protocol stack design and a focus on 6G to achieve SOF of the protocol stack functions, thereby realizing a flexible network.

[0066] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0067] In various embodiments of this application, the random access response carries information about the link between L2 and L3. The network side configures the link between L2 and L3 through the random access response, thereby enabling the terminal to complete the RRC registration process without establishing SRBs (such as SRB1, SRB2, and SRB3), thus achieving rapid configuration of the link between L2 and L3 of the terminal.

[0068] This application provides an information transmission method applied to a terminal, such as... Figure 1 As shown, the method includes:

[0069] Step 101: Send a random access request to the network side;

[0070] Step 102: Receive the Random Access Response (RAR) sent by the network side. The Random Access Response includes at least first information, which is used to establish a channel between the L2 and L3 of the terminal.

[0071] In practical applications, the terminal can also be referred to as a UE or a user.

[0072] In practical applications, L2 may include MAC and RLC layers, and L3 may include RRC layers. The specific protocol layers included in L2 and L3 can be set according to requirements. That is to say, other protocol layers belonging to L2 and L3 in mobile communication systems are also within the protection scope of this application, and the embodiments of this application do not limit them.

[0073] In practical applications, the channel between L2 and L3 of the terminal can be used to meet the user's QoS requirements, that is, to perform QoS guarantee.

[0074] Based on this, in one embodiment, the first information can indicate at least one channel between L2 and L3, with each channel corresponding to at least one QoS level, and each channel can perform QoS guarantee based on the corresponding QoS level; in other words, each channel has QoS guarantee capability.

[0075] In practical applications, each channel can correspond to different QoS levels, that is, different QoS guarantee requirements (i.e., QoS needs).

[0076] In practical applications, the channel can take the form of a bearer (such as a Data Radio Bearer (DRB)) or not a bearer, for example, ensuring QoS requirements through transmission. Ensuring QoS requirements through transmission means not establishing a bearer, such as not establishing a DRB as in related technologies.

[0077] In practical applications, the channel may also be called a QoS-oriented link (QOL), etc. This application embodiment does not limit the name of the channel, as long as its function is implemented.

[0078] In practical applications, at least one channel between L2 and L3 can be indicated by the channel identifier.

[0079] Therefore, in one embodiment, the first information may include the identifier of at least one channel, such as an ID.

[0080] In practical applications, when at least two channels between L2 and L3 are indicated by channel identifiers, the identifiers of the at least two channels may be continuous or discontinuous.

[0081] In practical applications, at least one channel between L2 and L3 can be indicated by the channel identifier and the number of channels.

[0082] Based on this, in one embodiment, the first information may include the identifier of at least one channel and third information, wherein the third information represents the number of channels.

[0083] In practical applications, when at least two channels between L2 and L3 are indicated by the channel identifier and the number of channels, the identifiers of the at least two channels can be continuous or discontinuous.

[0084] In practical applications, when the first information indicates at least two channels between L2 and L3, and the identifiers of the at least two channels are consecutive, the identifier of the first channel and the number of channels can be used to indicate the at least two channels between L2 and L3.

[0085] Based on this, in one embodiment, the first information may include second information and third information, wherein the second information represents the identifier of the first channel among at least two channels, the identifiers of the at least two channels are consecutive, and the third information represents the number of channels.

[0086] Here, the first channel refers to the channel corresponding to the first identifier in at least two consecutive identifiers, that is, the channel whose identifier number is the first digit. For example, as shown... Figure 2 As shown, in the case where L3 includes an RRC layer and L2 includes a MAC layer, assuming that the identifiers of the n+1 channels between the RRC layer and the MAC layer are 0 to n, where n is an integer greater than or equal to 1, then the first channel refers to channel _0, that is, the second information can contain 0, and the third information can contain n+1.

[0087] In practical applications, the specific method by which the random access response carries the first information can be configured according to requirements. For example, when L3 includes an RRC layer and L2 includes a MAC layer, it can be... Figure 3 Adding the second and third information to the random access response PDU shown, we obtain Figure 4 The random access response PDU shown carries the first information; wherein, MAC UE ID represents the ID assigned to the terminal, that is, the MAC layer defines the MAC's ability to assign UE IDs; Basic IDof QOL represents the starting value of the QOL ID configured by the network side this time, that is, the second information; Number of QOL represents the number of QOL IDs configured by the network side this time, that is, the third information; when Basic ID of QOL is 0 and Number of QOL is 8, the QOL configured by the network side is 0 to 7, that is, the first information indicates 8 channels numbered 0 to 7 between the RRC layer and the MAC layer.

[0088] In this embodiment of the application, in step 101, the terminal initiates a random access request according to its needs, that is, according to QoS requirements or levels.

[0089] Based on this, in one embodiment, the method may further include:

[0090] Send a random access request to the network side based on at least one QoS requirement or level.

[0091] When initiating random access, the terminal selects a preamble according to QoS requirements or levels. In one embodiment, the terminal can determine a preamble based on at least one QoS requirement or level, and use the determined preamble to send a random access request to the network side.

[0092] Here, the random access request includes a defined Preamble, namely the Preamble corresponding to the at least one QoS requirement or level.

[0093] In practical applications, the at least one QoS requirement or level can be at least one QoS requirement or level that the terminal may use.

[0094] Based on this, in one embodiment, the method may further include:

[0095] Determine at least one QoS requirement or level that may be used;

[0096] Determine the Preamble based on at least one QoS requirement or level that is identified as potentially usable.

[0097] In practical applications, the terminal can use an explicit mode to determine the preamble, meaning that the terminal and the network side can associate QoS requirements or levels with the preamble according to the same understanding. For example, the terminal and the network side can pre-store the association relationships (which can be understood as mapping rules) between QoS requirements, QoS levels, preambles, and channel identifiers as shown in Table 1. This relationship is indexed by the channel (i.e., the channel identifier), meaning that each channel can correspond to the same or different preambles and can correspond to different QoS requirements or levels. The terminal can determine a preamble corresponding to at least one potentially usable QoS requirement or level based on this relationship and send a random access request containing the preamble to the network side. After receiving the random access request, the network side can determine the identifier of at least one channel corresponding to the preamble based on this relationship and instruct the terminal, i.e., send a random access response carrying the first information to the terminal. In this way, by carrying first information to characterize QoS parameters or features (which can be expressed as Profile in English) in the random access response, the size of the random access response PDU can be reduced compared to the method of directly carrying QoS parameters or features in the random access response, thus reducing the overhead of the random access response.

[0098]

[0099] Table 1

[0100] Based on this, in one embodiment, determining the Preamble according to at least one QoS requirement or level may include:

[0101] By utilizing the correlation between the preamble and the QoS requirement or level, the preamble corresponding to the at least one QoS requirement or level is determined.

[0102] In practical applications, after receiving a random access request containing a preamble corresponding to at least one QoS requirement or level, the network side can determine the first information based on the preamble corresponding to the at least one QoS requirement or level. Specifically, the network side can utilize the association between the preamble and the channel identifier to determine the identifier of the channel corresponding to the preamble of the at least one QoS requirement or level, thereby obtaining the identifier of at least one channel; and determine the first information based on the identifier of the at least one channel.

[0103] Here, the specific association method between Preamble, QoS requirements, QoS levels, and channel identifiers can be set according to needs, such as in Table 1, and this embodiment does not limit this. Additionally, it should be noted that the terminal and the network side need to store the same association relationships, namely the association between Preamble and QoS requirements or levels, and the association between Preamble and channel identifiers, to achieve explicit selection of Preamble and implicit reporting of QoS requirements or levels, thereby reducing the overhead of random access.

[0104] The terminal can also use implicit mode to determine the preamble, that is, the terminal and the network side associate QoS requirements or levels with the preamble according to their respective understandings. In other words, the terminal and the network side map the preamble, QoS requirements, QoS levels, and channels according to their respective understandings. The mapping on the terminal side may be coarse-grained, and the mapping on the network side may be fine-grained. The specific mapping method can be set according to requirements, and this application embodiment does not limit this. For example, the terminal can select a suitable preamble based on its own capabilities (UE Capability) and send it to the network side. Based on the preamble, the network side can configure the channel between L2 and L3 for the terminal using preset rules (such as Table 1), that is, send a random access response carrying the first information to the terminal, thereby realizing explicit selection of the preamble and implicit reporting of QoS requirements or levels, thus reducing the overhead of random access.

[0105] In practical applications, the terminal can also explicitly report QoS requirements or levels. That is, the random access request can contain at least one QoS requirement or level, each QoS level can contain multiple QoS requirements, and each QoS requirement can contain multiple QoS parameters or features. In other words, the random access request directly carries at least one QoS requirement or level.

[0106] In one embodiment, the method may further include:

[0107] Based on the first information, establish at least one channel between L2 and L3.

[0108] Specifically, in practical applications, after receiving a random access response carrying the first information, the terminal can establish at least one channel between L2 and L3 based on the first information, that is, activate at least one channel between L2 and L3. In other words, the first information is used to activate the channel between L2 and L3 of the terminal, or it can be said that the first information is used to enable the channel between L2 and L3 of the terminal. It can be understood that the same channel is also established between L2 and L3 on the network side as on the terminal side. On both the terminal and network sides, when L2 and L3 interact, both L2 and L3 can select an appropriate channel for data transmission based on the characteristics of the data packets to be sent to L3 or to L2 as needed.

[0109] When L2 and L3 send data packets, they can use a preset algorithm to determine the importance of the data packets and automatically select an appropriate channel based on the importance. For example, if the RRC layer needs to send basic context signaling of the terminal to the MAC layer, and the importance priority is high, then a channel with high QoS guarantee capability will be selected; if the MAC layer needs to send information with lower importance priority to the RRC layer, then a channel with lower or general QoS guarantee capability can be selected. Furthermore, when the network-side MAC layer receives a random access request containing a preamble corresponding to at least one QoS requirement or level, it can send the message to the RRC layer using a channel with high QoS guarantee capability; when the terminal accesses the network, for the measurements reported by the terminal, the network-side MAC layer can choose a channel with lower or general QoS guarantee capability to send them to the RRC layer.

[0110] In practical applications, the network side can pre-establish at least one channel between L2 and L3. Specifically, the network side can establish QoS requirements or levels for data transmission over the air interface for each service type supported by the wireless air interface, and establish different channels between L2 and L3 for each QoS requirement or level. When establishing a channel between L2 and L3, the network side can use big data (i.e., historical service data) and a preset artificial intelligence (AI) algorithm to establish at least one channel based on the common QoS guarantee requirements of data transmitted between L2 and L3 by terminals in the network. In practical applications, the network side can pre-establish at least one channel via RRC signaling or through default configuration; this embodiment does not limit this. After receiving a random access request from a terminal, the network side can determine the available channel for the terminal from the pre-established channels based on the terminal's QoS requirements or level, determine the first information based on the determined available channel, and send a random access response carrying the first information to the terminal.

[0111] Accordingly, embodiments of this application also provide an information transmission method, applied to network devices (specifically, base stations), such as... Figure 5 As shown, the method includes:

[0112] Step 501: Receive a random access request sent by the terminal;

[0113] Step 502: Send a random access response to the terminal, the random access response containing at least first information, the first information being used to establish a channel between the L2 and L3 of the terminal.

[0114] In one embodiment, the random access request includes at least one Preamble corresponding to a QoS requirement or level; the method further includes:

[0115] The first information is determined based on the preamble corresponding to the at least one QoS requirement or level.

[0116] In one embodiment, determining the first information based on the preamble corresponding to the at least one QoS requirement or level includes:

[0117] By utilizing the association between the Preamble and the channel identifier, the identifier of the channel corresponding to the Preamble corresponding to the at least one QoS requirement or level is determined, thereby obtaining the identifier of at least one channel.

[0118] Based on the identifier of the at least one channel, the first information is determined. The first information indicates at least one channel between L2 and L3. Each channel corresponds to at least one QoS level, and each channel can perform QoS guarantee based on the corresponding QoS level.

[0119] It should be noted that the specific processing procedures of the network device have been described in detail above and will not be repeated here.

[0120] Accordingly, embodiments of this application also provide an information transmission method, such as... Figure 6 As shown, the method includes:

[0121] Step 601: The terminal sends a random access request (Msg1: RA Request) to the network side, and then proceeds to step 602;

[0122] Step 602: The network side sends a random access response (which can be expressed as New Msg2: RAResponse) to the terminal, and then proceeds to step 603;

[0123] Step 603: The terminal sends a random access response confirmation message (ACK forMsg2) to the network side.

[0124] In step 601, the terminal can select a suitable Preamble based on the QoS guarantee requirements (i.e., QoS requirements or levels) of the content to be transmitted; by sending a random access request carrying the Preamble to the network side, the terminal can indicate at least one QoS requirement or level that it may use, for example, by using the association shown in Table 1, multiple QoS levels can be indicated by one Preamble.

[0125] In step 602, after receiving the Preamble, the network side can determine the channel between L2 and L3 of the terminal based on the Preamble, for example, by using the association relationship shown in Table 1 to determine at least one channel; and configure the channel to the terminal through a random access response, that is, send a random access response carrying the first information to the terminal.

[0126] The information transmission method provided in this application embodiment involves a terminal sending a random access request to the network side and receiving a random access response from the network side. The random access response includes at least first information, which is used to establish a channel between the terminal's L2 and L3 layers. The solution provided in this application embodiment carries information about the link between L2 and L3 in the random access response. The network side configures the link between L2 and L3 through the random access response, enabling the terminal to establish a channel between L2 and L3 based on the configured information, such as a channel between the RRC layer and the MAC layer, or a channel between the RRC layer and the RLC layer. This allows the terminal to complete the RRC registration process without establishing SRBs (such as SRB1, SRB2, and SRB3), achieving rapid configuration of the link between the terminal's L2 and L3 layers. Furthermore, when the terminal interacts with the network side, the channel between L2 and L3 can be used to meet the user's data transmission requirements, such as performing QoS guarantees, to achieve SOF-based protocol stack functionality, and ultimately realize SO-RAN.

[0127] In addition, the solution provided in this application embodiment can quickly achieve random access in just two steps, and the random access response adds less information (i.e., the first information), thereby improving the efficiency of terminal access to the network.

[0128] Third, the solution provided in this application's embodiments proposes a HARQ mechanism for random access responses (i.e., Figure 6 Step 603 shown is used to enable highly feasible data transmission.

[0129] Fourth, the solution provided in this application, when L3 includes the RRC layer and L2 includes the MAC layer, utilizes the channel between the RRC and MAC layers to reconstruct the functional definition of the RRC layer and the definition of the traditional access (AS) layer's "link" or "connection" (i.e., the definition of an RRC connection). In other words, the RRC layer can re-define the terminal context (UE context). For example, the RRC layer can assign its own identifier (UE ID) to the terminal, or it can use the identifier assigned to the terminal by the MAC layer. Furthermore, it can avoid establishing an RRC connection, i.e., without establishing a bearer, requiring only simple activation information (i.e., ... Figure 6 The New Msg2 in the code can ensure QoS through data transmission between the RRC layer and the MAC layer, thereby enabling the terminal to achieve RRC authentication on the network side by registering the service.

[0130] Fifth, in the case where L3 includes the RRC layer and L2 includes the MAC layer, since the channel between the RRC layer and the MAC layer on the network side is fixed, when the terminal moves from one base station to another, it does not need to perform the RRC Connection switching in the related technology, thereby achieving "0" handover on the RAN.

[0131] To implement the terminal-side method of this application embodiment, this application embodiment also provides an information transmission device, which is installed on the terminal, such as... Figure 7 As shown, the device includes:

[0132] The first sending unit 701 is used to send a random access request to the network side;

[0133] The first receiving unit 702 is used to receive a random access response sent by the network side. The random access response includes at least first information, which is used to establish a channel between the L2 and L3 of the terminal.

[0134] In one embodiment, the device further includes a first processing unit for:

[0135] Determine the preamble based on at least one QoS requirement or level;

[0136] Accordingly, the first sending unit 701 is also used to send a random access request to the network side using a determined Preamble.

[0137] In one embodiment, the first processing unit is further configured to determine at least one QoS requirement or level that may be used.

[0138] In one embodiment, the first processing unit is further configured to determine the Preamble corresponding to the at least one QoS requirement or level by utilizing the correlation between the Preamble and the QoS requirement or level.

[0139] In one embodiment, the first processing unit is further configured to establish at least one channel between L2 and L3 based on the first information.

[0140] In practical applications, the first sending unit 701 and the first receiving unit 702 can be implemented by the communication interface in the information transmission device; the first processing unit can be implemented by the processor in the information transmission device.

[0141] To implement the network device-side method of this application embodiment, this application embodiment also provides an information transmission device, disposed on the network device, such as... Figure 8 As shown, the device includes:

[0142] The second receiving unit 801 is used to receive random access requests sent by the terminal;

[0143] The second sending unit 802 is used to send a random access response to the terminal. The random access response includes at least first information, which is used to establish a channel between the L2 and L3 of the terminal.

[0144] In one embodiment, the random access request includes at least one QoS requirement or level corresponding to a Preamble; the device further includes a second processing unit for determining the first information based on the at least one QoS requirement or level corresponding to the Preamble.

[0145] In one embodiment, the second processing unit is further configured to:

[0146] By utilizing the association between the Preamble and the channel identifier, the identifier of the channel corresponding to the Preamble corresponding to the at least one QoS requirement or level is determined, thereby obtaining the identifier of at least one channel.

[0147] Based on the identifier of the at least one channel, the first information is determined. The first information indicates at least one channel between L2 and L3.
