Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an information processing method, apparatus, device and readable storage medium. Background Technology

[0002] In 6G, the SBA RAN (Service Based Architecture Radio Access Network) scheme was proposed. In the SBA RAN scheme, a UE (User Equipment) can simultaneously have multiple L3UP (layer 3 User Plane), SDAP (Service Data Adaptation Protocol), PDCP (Packet Data Convergence Protocol), and RLC (Radio Link Control) protocol functionalities. For example, URLLC (Ultra-Reliable and Low Latency Communications) corresponds to one L3UP / SDAP / PDCP / RLC protocol functionality, and eMBB (Enhance Mobile Broadband) corresponds to one L3UP / SDAP / PDCP / RLC protocol functionality, etc.

[0003] Therefore, at the Access Stratum (AS) layer, the correspondence between protocol sublayers exhibits many-to-one or one-to-many relationships, and the functional bodies of the same protocol stack sublayer are not unique. When transmitting data packets (Protocol Data Units, PDUs) between layers, the functional bodies of the source and destination protocol sublayers are not unique. Therefore, ensuring consistency between the sending and receiving ends is a technical problem that needs to be solved. Summary of the Invention

[0302] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0303] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0304] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0305] The technical content related to the embodiments of the present invention will be described below.

[0306] To achieve the design goal of a Lite Network for next-generation mobile communications, a User Plane (UP) function is proposed to be introduced into Layer 3 (L3) for data processing. This UP function (denoted as L3UP) is introduced into L3 of the Access Stratum (AS) layer (in 5G systems, the AS layer's Layer 3 protocol only includes the Radio Resource Control (RRC) protocol sublayer). In 3G / 4G / 5G systems, L3 at the AS layer (terminal side, RRC protocol layer for the network side) only has a Control Plane (CP), i.e., only the RRC protocol layer (or its sublayer), which performs radio resource control functions.

[0307] The L2 packet processing function of the AS layer has been redesigned. The new L2 packet processing function mainly takes into account the characteristics of the upper layer service data and combines the channel characteristics of the lower layer air interface to form QoS (Quality of Service) indicators and operations that take into account both air interface and service characteristics.

[0308] For L3 of the AS layer, in addition to the traditional Radio Resource Control (RRC, L3 CP) function, the L3 UP function is added to process data packets.

[0309] like Figure 1 The diagram shown is a functional schematic of the AS layer protocol stack in 6G.

[0310] The L3 UP (User Plane) of the AS layer has the function of sending IP (Internet Protocol) packets once or more. With the introduction of the L3 UP function, the existing data processing functions of L2 need to be redefined.

[0311] The introduction of L3 UP brings a new way of data processing at the AS layer, enabling seamless and lossless forward transfer of data when the user moves.

[0312] Figure 2 A 6G flexible protocol stack scheme is presented. In this scheme, there are multiple correspondences between different protocol sublayers, and multiple functionalities can coexist within a single protocol sublayer. At the AS layer, the correspondence between protocol sublayers exhibits many-to-one or one-to-many relationships, and the functionalities within the same protocol stack sublayer are not unique. When transmitting data packets (Protocol Data Units, PDUs) between layers, the source and destination protocol sublayer functionalities are not unique. Therefore, the sending and receiving ends need unified RRC signaling to ensure consistent data processing between them.

[0313] To address the aforementioned issues, this application proposes an RRC signaling scheme for a flexible wireless protocol stack. In this application, low-overhead end-to-end wireless link control is achieved by defining configuration schemes for each protocol sublayer of the flexible protocol stack within the RRC signaling. Furthermore, the RRC signaling provides a unified configuration scheme, thereby enabling efficient data transmission capabilities in the wireless network. It should be noted that this application primarily describes how to implement routing between multiple protocol sublayer functionalities with the same function when they are established simultaneously.

[0314] For example, one application scenario of the solution in this application embodiment is: one SDAP protocol sublayer corresponds to multiple independent PDCP protocol sublayer functional bodies at the same time, and the QoS Flow in the SDAP protocol sublayer can be mapped to one or more independent PDCP protocol sublayer functional bodies; conversely, one PDCP protocol sublayer functional body can correspond to multiple SDAP protocol sublayer functional bodies.

[0315] exist Figure 1The diagram illustrates a flexible protocol stack scheme for the 6G AS layer. In this scheme, various protocol sublayers (such as RRC, L3UP, SDAP, PDCP, RLC, MAC, etc.) exhibit multiple connection methods, requiring the RRC signaling configuration scheme to be reconfigured to meet the requirements of the aforementioned protocol stack topology.

[0316] Because the protocol stack requires peer-to-peer operation, meaning that the sending end and the receiving end need to have equivalent protocol processing functions, the basic architecture of the RRC signaling scheme in this application embodiment is: based on the layering of each protocol sublayer, designing the functions of each protocol sublayer and the topology between the protocol sublayers.

[0317] Regarding the functionality of the protocol sublayers, compatibility definitions are made based on the existing functions of the 5G protocol sublayers, including adding, removing, or modifying the functions of the 5G protocol sublayers and defining new protocol sublayers. Regarding the topology between protocol sublayers, compatibility definitions are made based on the relationships between the 5G protocol sublayers, and improvements are made to the existing bearer connection methods.

[0318] The implementation process of the embodiments of this application will be described in detail below with reference to specific examples.

[0319] See Figure 3 , Figure 3 This is a flowchart of the information processing method provided in the embodiments of this application, applied to a terminal, such as... Figure 3 As shown, it includes the following steps:

[0320] Step 301: Obtain RRC signaling, wherein the RRC signaling includes indication information.

[0321] In practical applications, this indication information can be carried in the following RRC signaling processes:

[0322] RRC connection establishment (RRC Setup Request, RRC Setup, RRC Setup Complete) and RRC reconfiguration (RRC Reconfiguration, RRC Reconfiguration Complete).

[0323] That is, the terminal can request the network device to send the instruction information to it, or the network device can send the instruction information to the terminal as needed.

[0324] Step 302: Perform one or more of the following actions according to the instruction information:

[0325] Establish protocol sublayer functionalities;

[0326] Configure the connection relationships between protocol sublayer functionalities.

[0327] In the embodiments of this application, the protocol stack sublayer functional body can be understood as the functional body of each protocol sublayer running in the terminal and / or network device (such as base station). A protocol sublayer can establish one or more functional bodies at the same time.

[0328] In this embodiment, the terminal can establish protocol sublayer functional bodies and / or set connection relationships between protocol sublayer functional bodies according to the indication information of the RRC signaling of the network device. Therefore, using the solution of this embodiment, even when there is a many-to-one or one-to-many relationship between inter-layer protocol sublayers, and the functional bodies of the same protocol stack sublayer are not unique, consistency between the sending end and the receiving end can be guaranteed, thereby reducing the overhead of end-to-end radio link control.

[0329] The specific implementation method of step 302 above is described below.

[0330] (1) Establish protocol sublayer functionalities.

[0331] In the embodiments of this application, one or more of the following functional bodies can be established:

[0332] Establish one or more functional units in L3, including: RRC protocol sublayer functional unit, one or more L3UP protocol sublayer functional units;

[0333] Establish one or more of the following functional units in L2: one or more SDAP protocol sublayer functional units, one or more PDCP protocol sublayer functional units, one or more RLC protocol sublayer functional units, and one or more MAC protocol sublayer functional units.

[0334] Establish one or more PHY protocol sublayer functional bodies in L1.

[0335] Specifically, one or more functional units are established in the L2 control plane, including: one or more PDCP protocol sublayer functional units and one or more RLC protocol sublayer functional units. One or more functional units are established in the L2 user plane, including: one or more Service Data Adaptation Protocol (SDAP) protocol sublayer functional units, one or more PDCP protocol sublayer functional units, and one or more RLC protocol sublayer functional units.

[0336] The one or more Media Access Control (MAC) protocol sublayer functionalities include C-MAC and one or more D-MACs.

[0337] In practical applications, the specific protocol sublayer functionalities that need to be established can be determined based on actual needs.

[0338] The functional components of each protocol sublayer are described below:

[0339] L3UP: The functional unit in the L3 layer of the AS layer responsible for packet processing, such as... Figure 1 The description.

[0340] The basic functions of protocol sublayers such as RRC, SDAP, PDCP, RLC, MAC, and PHY are based on existing 5G functions, and the functions are reconfigured as needed during the definition of the new topology.

[0341] The RRC protocol sublayer function is used for control plane functions, and the one or more L3UP protocol sublayer functions are used for user plane functions. Only one RRC protocol sublayer function can be established on the network side or the terminal side. That is, for a single terminal, only one RRC protocol sublayer function is established, while multiple RRC protocol sublayer functions can be established simultaneously for any other protocol sublayer.

[0342] like Figure 4 The diagram shown is a schematic representation of topology planning based on protocol sublayers in an embodiment of this application. For ease of description, in... Figure 4 In the diagram, the numbers 1, 2, 3, and 4, along with the corresponding four dividing lines (Line 1, Line 2, Line 3, Line 4), are used for identification. Specifically:

[0343] Line 1 marks the boundary between Layer 3 (L3) and Layer 2 (L2). The connection relationship between L3 and L2 is defined here. L3 is functionally divided into the RRC protocol sublayer and the L3UP protocol sublayer. The RRC sublayer is responsible for control plane (CP) functions, while the L3UP sublayer is responsible for user plane (UP) functions. The RRC sublayer can directly connect to the PDCP protocol sublayer or the MAC protocol sublayer (Medium Access Control), including: connecting to both PDCP and MAC sublayers simultaneously, or connecting only to either the PDCP or MAC sublayer.

[0344] Line 2 is the boundary line within Layer 2 (L2). It defines the connection relationship between the SDAP protocol sublayer function, PDCP protocol sublayer function, and MAC protocol sublayer function of L2.

[0345] Line 3 is the boundary line within Layer 2 (L2). It defines the connection relationships between all protocol sublayer functionalities and MAC protocol sublayer functionalities in L2.

[0346] The MAC layer shields the physical layer from the impact of differences in the upper-layer protocol stacks. The MAC layer orchestrates and schedules the physical layer's physical resources according to the requirements of the upper layers. Therefore, the MAC layer may have connections with all its upper-layer protocol sublayers, as described in Lines 1 and 2.

[0347] The MAC protocol sublayer function is divided into two main parts in terms of functional logic: (1) Common MAC function (C-MAC) for upper layer connection processing and air interface transmission orchestration; (2) Dedicated MAC function (D-MAC) for wireless resource scheduling of each physical layer, which is responsible for resource allocation, control and scheduling under each physical transmission standard.

[0348] Line 4 marks the boundary between Layer 2 (L2) and Layer 1 (L1, Physical Layer, PHY). It defines the connection relationship between the MAC protocol sublayer and the PHY.

[0349] The MAC layer orchestrates and schedules the physical layer's physical resources according to the requirements of the upper layer. The physical layer can be diverse, such as OFDM (Orthogonal Frequency Division Multiplexing), visible light, Wi-Fi (Wireless Fidelity), and other wireless transmission standards. Under the unified scheduling of the MAC layer, data is transmitted.

[0350] (2) Set the connection relationship between the protocol sublayer functional bodies.

[0351] By defining the connection relationships between different protocol sublayers of the flexible wireless protocol stack, low-overhead flexible data transmission can be achieved. In the embodiments of this application, the connection relationships of each protocol sublayer can be configured according to two connection relationships: CP and UP.

[0352] In the embodiments of this application, the indication information can be used to indicate different content.

[0353] I. The indication information can be used to indicate the connection configuration relationship between the RRC protocol sublayer functional body and the lower layer functional body of the control plane.

[0354] The lower-level functional units of the control plane include: one or more PDCP protocol sublayer functional units, and / or one or more MAC protocol sublayer functional units.

[0355] In this step, according to the instruction information, the connection relationship between the RRC protocol sublayer function and one or more PDCP protocol sublayer functions is set; and / or, the connection relationship between the RRC protocol sublayer function and one or more MAC protocol sublayer functions is set.

[0356] The indication information may include the identifiers of the one or more PDCP protocol sublayer functional units. When establishing a connection, the connection relationship between the RRC protocol sublayer functional unit and the one or more PDCP protocol sublayer functional units can be set according to their identifiers; wherein the identifiers of the one or more PDCP protocol sublayer functional units are uniformly numbered. The identifier may be, for example, an ID.

[0357] Alternatively, the indication information may include: configuration information of the signaling bearer (SB) between the RRC protocol sublayer functional body and the lower layer functional body of the control plane;

[0358] The configuration information of the SB includes one or more of the following:

[0359] SB Identifier: SB ID, a unique SB number for all connected RRC protocol sublayer functional units;

[0360] Information used to indicate that SB is a bidirectional bearer;

[0361] The identifier of the protocol sublayer function that the SB connects to: for example, the function ID. For example, in an RRC-MAC connection, the identifiers of the RRC and MAC protocol sublayer functions that the SB connects to need to be configured.

[0362] QoS guarantee requirements (QoS parameters) when SB transmits information (uplink or downlink); for example, an SB connected to a MAC protocol sublayer function needs to specify the quality of service requirements to be met when sending packets;

[0363] The SB, which connects to the MAC protocol sublayer functional body, configures the data packet processing functions of the MAC protocol sublayer functional body. For example, the guaranteed minimum or maximum value of MCS (Modulation and Coding Scheme), the maximum number of HARQ (Hybrid Automatic Repeat Request) retransmissions, whether HARQ parallel processes can be started to send PDUs in multiple parallel paths, the maximum or maximum transmission power, the priority when scheduling the SB, the mode of HARQ or HARQ process (asynchronous mode, synchronous mode), the timing mode of uplink feedback, and the physical channel or physical time domain or frequency domain resources for uplink feedback.

[0364] Configuration parameters of the SB connecting the PDCP protocol sublayer function on the PDCP protocol sublayer function and / or RLC protocol sublayer function, such as the function configuration, sorting window parameter configuration, processing mode and other parameters of the SB connecting the PDCP protocol sublayer function on the PDCP protocol sublayer function and / or RLC protocol sublayer function.

[0365] The identifier of the newly established PDCP protocol sublayer function and / or the identifier of the newly established RLC protocol sublayer function, such as the ID of the newly established PDCP protocol sublayer function and / or RLC protocol sublayer function.

[0366] The transmission configuration parameters of the transmission network layer (TNL) corresponding to each SB include, for example, the configuration of various TNL types such as IP, SCTP (Stream Control Transmission Protocol), GTP (General Data Transfer Platform), or direct transmission link MAC, the QoS guarantee capability of each transmission link, and transmission link parameters.

[0367] Therefore, in this step, based on the configuration information of the SB, one or more SBs are set between the RRC protocol sublayer function and one or more PDCP protocol sublayer functions; and / or based on the configuration information of the SB, one or more SBs are set between the RRC protocol sublayer function and one or more MAC protocol sublayer functions.

[0368] The SB between the RRC protocol sublayer function and one or more PDCP protocol sublayer functions is uniformly numbered with the SB between the RRC protocol sublayer function and one or more MAC protocol sublayer functions.

[0369] Combination Figure 4 Describe in detail the process of establishing the connection relationship between the RRC protocol sublayer functional body and other protocol sublayer functional bodies according to the above two different instruction information.

[0370] 1. RRC-PDCP:

[0371] There are two ways to define the connection between the RRC protocol sublayer function and the PDCP protocol sublayer function:

[0372] (1) Define the PDCP protocol sublayer function ID. All PDCP protocol sublayer functions connected to an RRC protocol sublayer function are uniformly numbered. Each PDCP protocol sublayer function number (such as ID) identifies a route, identifies a PDCP protocol sublayer function, and also identifies the path for sending information from the RRC protocol sublayer function to the PDCP protocol sublayer function; conversely, the PDCP protocol sublayer function directly obtains the path for sending information based on the ID assigned to it by the RRC protocol sublayer function.

[0373] (2) Define the Signaling Bearer (SB). An SB is established between each RRC protocol sublayer function and each PDCP protocol sublayer function connected to it. All SBs connected to this RRC protocol sublayer function are assigned a unique number. This SB is used to implement the connection between the RRC and PDCP protocol sublayer functions. The RRC protocol sublayer function may have a sequencing function to ensure the correct order in which multiple PDCP protocol sublayer functions send information to the RRC protocol sublayer function.

[0374] Figure 5 This paper illustrates a connection scheme between RRC protocol sublayer functions and PDCP protocol sublayer functions based on PDCP protocol sublayer function IDs or SBs. In both schemes, the RRC protocol sublayer functions have a repeating function, meaning that the sending end's RRC protocol sublayer functions send RRC signaling PDUs in sequence, and the receiving end's RRC protocol sublayer functions can correctly receive the corresponding RRC signaling PDUs in the same order.

[0375] In addition, each ID (PDCP ID or SB ID) in the two connection methods represents a processing method for an RRC signaling PDU, such as whether to use the traditional ASN.1 encoding method or whether to use an RRC-bearing signaling PDU.

[0376] The information exchanged between the PDCP protocol sublayer function and the RRC protocol sublayer function includes RRC signaling PDUs, the status of signaling PDU transmission reported by PDCP (whether the transmission was successful, whether it was retransmitted, the transmission time delay, etc.), and the measurement of the PDCP protocol sublayer function's own operating status reported by itself.

[0377] 2. RRC-MAC:

[0378] The Signaling Bearer (SB) connects the RRC protocol sublayer functions and the MAC protocol sublayer functions. This SB carries the QoS guarantee requirements from the RRC layer to the MAC layer, and from the MAC layer through the physical layer to the air interface. The MAC layer can obtain the aforementioned QoS guarantee information (requirements) through this SB ID. The RRC protocol sublayer functions can identify that this information originates from the MAC layer through the SB ID.

[0379] Through this SB, the information exchanged between the MAC protocol sublayer function and the RRC protocol sublayer function includes RRC signaling PDUs, the status of the signaling PDUs reported by the MAC (the status information when the HARQ sends the PDU), information on the radio resources allocated by the MAC, and information on the physical channel configuration selected by the MAC.

[0380] like Figure 6 The diagram illustrates the overall scheme for the connection between RRC protocol sublayer functional entities and their lower layers based on SBs. Centered on the RRC protocol sublayer functional entity, SBs with uniform numbering are established to realize routing between RRC and various protocol sublayers. Depending on the connected protocol sublayer, the attributes of the SBs differ. For example, the SB connecting to the MAC protocol sublayer functional entity carries signaling bearers with QoS requirements, while the SB connecting to the PDCP protocol sublayer functional entity represents PDCP links with different processing capabilities (e.g., PDCP with duplication capability, PDCP with single-link capability, etc.).

[0381] II. The indication information is used to indicate the connection configuration relationship between one or more L3UP protocol sublayer functions and user plane lower-layer functions. The user plane lower-layer functions include: one or more SDAP protocol sublayer functions, and / or, one or more MAC protocol sublayer functions.

[0382] In this step, according to the instruction information, the connection relationship between the one or more L3UP protocol sublayer functions and one or more SDAP protocol sublayer functions is set; and / or, the connection relationship between the one or more L3UP protocol sublayer functions and one or more MAC protocol sublayer functions is set.

[0383] The indication information includes: the identifiers of the one or more L3UP protocol sublayer functional units, and the identifiers of the one or more SDAP protocol sublayer functional units. In this case, the connection relationship between the one or more L3UP protocol sublayer functional units and the one or more SDAP protocol sublayer functional units can be set according to the identifiers of the one or more L3UP protocol sublayer functional units and the identifiers of the one or more SDAP protocol sublayer functional units.

[0384] Alternatively, the indication information may include: configuration information of the DB between one or more user plane high-level functional units and user plane low-level functional units;

[0385] The configuration information of the DB includes:

[0386] DB Identification: A unique number for all DBs connecting all L3UP protocol sublayer functions and all their lower-level SDAP protocol sublayer functions / MAC protocol sublayer functions; A unique number for all DBs connecting all SDAP protocol sublayer functions and all their lower-level PDCP protocol sublayer functions / MAC protocol sublayer functions;

[0387] Information used to indicate that the DB is a bidirectional bearer;

[0388] The DB is connected to two protocol sublayer functional bodies, such as functional body IDs. For example, for SDAP-MAC, the DB needs to be configured with the identification information of the SDAP protocol sublayer functional body and the MAC protocol sublayer functional body.

[0389] QoS guarantee requirements (QoS parameters) when DB transmits information (uplink or downlink); for example, a DB connected to a MAC protocol sublayer function needs to specify the quality of service requirements to be met when sending data packets;

[0390] The DB connecting to the MAC protocol sublayer function body configures the data packet processing parameters of the MAC protocol sublayer function body, such as the guaranteed minimum or maximum MCS value, the maximum number of HARQ retransmissions, whether to start the HARQ parallel process to send PDUs in multiple parallel paths, the maximum or maximum transmission power, the priority when scheduling SB, the mode of HARQ or HARQ process (asynchronous mode, synchronous mode), the timing mode of uplink feedback, and the physical channel or physical time domain or frequency domain resources of uplink feedback, etc.

[0391] Configuration parameters for the DB connecting to the PDCP protocol sublayer function on the PDCP protocol sublayer function and / or RLC protocol sublayer function: For example, the DB's function configuration, sorting window parameter configuration, processing mode, and other parameters on the PDCP protocol sublayer function and / or RLC protocol sublayer function. The PDCP protocol sublayer function has routing capabilities, ensuring that data packets are sent to the correct SDAP protocol sublayer function.

[0392] The identifiers of newly established PDCP protocol sublayer functions and / or newly established RLC protocol sublayer functions: such as the ID of newly established PDCP protocol sublayer functions and / or the ID of newly established RLC protocol sublayer functions.

[0393] Indication used to indicate that the SDAP protocol sublayer function has routing capabilities: SDAP has routing capabilities, which enables data packets to be sent to the correct L3UP protocol sublayer function.

[0394] Indication for MAC protocol sublayer functions having routing capabilities: MAC has routing capabilities, which enables data packets to be sent to the correct L3UP protocol sublayer function or SDAP protocol sublayer function.

[0395] The transmission configuration parameters for each DB's corresponding TNL include: configurations for various TNL types such as IP, SCTP, GTP, or direct transmission link MAC; QoS guarantee capabilities for each transmission link; and transmission link parameters.

[0396] At this time, the terminal can set one or more DBs between one or more user plane high-level functional units and user plane low-level functional units according to the configuration information of the DB.

[0397] Wherein, the user plane higher-layer functional units include an L3UP protocol sublayer functional unit, and the user plane lower-layer functional units include: one or more SDAP protocol sublayer functional units, and / or one or more MAC protocol sublayer functional units; or, the user plane higher-layer functional units include an SDAP protocol sublayer functional unit, and the user plane lower-layer functional units include: one or more PDCP protocol sublayer functional units, and / or one or more MAC protocol sublayer functional units.

[0398] Combination Figure 4 Describe in detail the process of establishing the connection relationship between the RRC protocol sublayer functional body and other protocol sublayer functional bodies according to the two different instruction information mentioned above.

[0399] The L3UP protocol sublayer function can directly connect to the SDAP protocol sublayer function or the MAC protocol sublayer function, including: connecting to both the SDAP protocol sublayer function and the MAC protocol sublayer function simultaneously, or connecting to only the SDAP protocol sublayer function or the MAC protocol sublayer function.

[0400] 1. L3UP-SDAP:

[0401] There are two ways to define the connection between the L3UP protocol sublayer function and the SDAP protocol sublayer function:

[0402] (1) A unique ID is assigned to each L3UP protocol sublayer function and SDAP protocol sublayer function through RRC signaling. A route is identified by the L3UP protocol sublayer function ID and the SDAP protocol sublayer function ID, which means that the path of the data packets exchanged between L3UP and SDAP is identified.

[0403] (2) By defining a Data Bearer (DB), RRC establishes a DB between each L3UP and SDAP sublayer functionalities that need to connect. All DBs established between L3UP and SDAP sublayer functionalities are assigned a unique number. Each DB carries QoS guarantee information (requirements) for data packets transmitted between the SDAP and L3UP sublayer functionalities. Through each DB, the SDAP and L3UP sublayer functionalities can identify each other and obtain routing information.

[0404] Figure 7 The diagram illustrates two connection methods between L3UP and SDAP. In both schemes, L3UP has a sequencing function, meaning that the transmitting SDAP sends SDAP PDUs in sequence, and the receiving SDAP can correctly receive the corresponding SDAP PDUs in the same order.

[0405] Each DB carries QoS guarantee information (requirements) for each SDAP link from the L3UP protocol sublayer function. Using this DB ID, the L3UP protocol sublayer function can identify which SDAP protocol sublayer function this information originates from.

[0406] 2. L3UP-MAC:

[0407] The L3UP protocol sublayer function and the MAC protocol sublayer function are connected by defining a Data Bearer (DB).

[0408] The RRC establishes a database (DB) between each L3UP and MAC sublayer function that needs to connect. All DBs established between L3UP and MAC sublayer functions are assigned a unique number. Each DB carries QoS guarantee information (requirements) for data packets transmitted between the MAC and L3UP sublayer functions. Through each DB, the MAC and L3UP sublayer functions can identify each other and obtain routing information.

[0409] This DB carries the QoS guarantee requirements from the L3UP PDU from the L3UP layer to the MAC layer, and from the MAC layer to the air interface via the physical layer. The MAC layer can obtain this QoS guarantee information through this DB ID. The L3UP protocol sublayer function can also identify that this information originates from the MAC layer through this DB ID.

[0410] Through this DB, the information exchanged between the MAC protocol sublayer function and the L3UP protocol sublayer function includes uplink and downlink data packets, and the status of data packet transmission reported by the MAC protocol sublayer function (status information when HARQ (Hybrid Automatic Repeat Request) sends PDUs).

[0411] Figure 8 This illustrates the overall scheme for L3UP protocol sublayer functions to connect to their lower layers based on a database (DB). A DB with a uniform number is established around all L3UP protocol sublayer functions to implement routing between all L3UP protocol sublayer functions and various protocol sublayers. The DB's attributes differ depending on the connected protocol sublayer. For example, a DB connecting to a MAC protocol sublayer function carries data with QoS requirements and can be in the form of a QoS flow; a DB connecting to an SDAP protocol sublayer function function can use an IP flow.

[0412] As mentioned earlier, Line 2 is the boundary line within Layer 2 (L2). It defines the connection relationships between L2's SDAP, PDCP, and MAC.

[0413] like Figure 9The diagram illustrates the overall scheme for SDAP protocol sublayer functions to connect to their lower layers based on a Data Base (DB). A uniquely numbered DB is established around all SDAP protocol sublayer functions to facilitate routing between all SDAP protocol sublayer functions and various protocol sublayers. The DB's attributes differ depending on the connected protocol sublayer. For example, the DB connecting to the MAC protocol sublayer function carries QoS requirements as a data bearer and can be in the form of a (MAC) SDU flow; the DB connecting to the PDCP protocol sublayer function function adopts the traditional DRB (Data Radio Bearer) form to achieve 5G SDAP-PDCP connection compatibility.

[0414] exist Figure 8 and Figure 9 In 5G systems, the connection relationship between SDAP and PDCP and their upper layers (the upper layer of SDAP is UPF, and the upper layer of PDCP is SDAP) is one-to-one, that is, one SDAP corresponds to one UPF, and one PDCP corresponds to one SDAP. However, in the embodiments of this application, there are multiple upper layers corresponding to the SDAP protocol sublayer function and the PDCP protocol sublayer function, so routing functions need to be added to both.

[0415] III. The indication information is used to indicate the connection configuration relationship between one or more MAC protocol sublayer functions and one or more RLC protocol sublayer functions.

[0416] In this step, the connection between one or more MAC protocol sublayer functional units and one or more RLC protocol sublayer functional units is set using a logical channel.

[0417] As mentioned earlier, Line 3 is the boundary line within Layer 2 (L2). It defines the connection relationships between all protocol sublayers and the MAC layer of L2.

[0418] The MAC protocol sublayer function connects to the RLC protocol sublayer function and RRC protocol sublayer function on the control plane, as well as the RLC protocol sublayer function, SDAP protocol sublayer function and L3UP protocol sublayer function on the user plane.

[0419] The MAC layer shields the physical layer from the impact of differences in the upper-layer protocol stacks. The MAC layer orchestrates and schedules the physical layer's physical resources according to the requirements of the upper layers. Therefore, the MAC layer may have connections with all its upper-layer protocol sublayers, as described in Lines 1 and 2.

[0420] The MAC layer is logically divided into two parts: (1) Common MAC function (C-MAC) for upper layer connection processing and air interface transmission orchestration; (2) Dedicated MAC function (D-MAC) for wireless resource scheduling of each physical layer, which is responsible for resource allocation, control and scheduling under each physical transmission standard.

[0421] IV. The indication information is used to indicate the connection configuration relationship between one or more MAC protocol sublayer functions and one or more PHY protocol sublayer functions. In this step, the connection relationship between one or more MAC protocol sublayer functions and one or more PHY protocol sublayer functions is set according to the type of the one or more PHY protocol sublayer functions. Specifically, according to the type of the one or more PHY protocol sublayer functions, the corresponding D-MAC is configured, and orchestration and scheduling are performed through C-MAC.

[0422] As mentioned earlier, Line 4 is the boundary between Layer 2 (L2) and Layer 1 (L1, Physical Layer, PHY). It defines the connection relationship between the MAC protocol sublayer and the PHY.

[0423] The MAC layer orchestrates and schedules the physical layer's physical resources according to the requirements of the upper layer. The physical layer can be diverse, such as OFDM (Orthogonal Frequency Division Multiplexing), visible light, Wi-Fi (Wireless Fidelity), and other wireless transmission standards. Under the unified scheduling of the MAC layer, data is transmitted.

[0424] It should be noted that, in this embodiment, there can be one or more DBs or SBs between two connected protocol sublayer functional bodies. When establishing protocol sublayer functional bodies and DBs connecting different protocol sublayers via RRC signaling, the establishment is performed for a single terminal. Furthermore, in this embodiment, RRC signaling can synchronously configure both the network side and the terminal, thereby ensuring protocol consistency between them. For network devices, the processing method based on RRC signaling is the same as that for terminals.

[0425] As can be seen from the above description, the solution using the embodiments of this application overcomes the limitation of inflexible selection between layers in the 5G protocol stack, realizing flexible scaling of protocol stack functions; it achieves protocol stack consistency through RRC signaling configuration, realizing efficient data transmission capabilities of the wireless network, and enabling a single terminal to simultaneously establish different protocol sublayer functional bodies with the same protocol functions; it lays the foundation for a protocol stack solution for SBA RAN; it lays the foundation for the definition of wireless slicing, so that different slices serving the same terminal can have the same or different protocol stack functions through this protocol stack solution; and it lays the foundation for customizing AS layer protocol stack functions according to different service requirements in 6G.

[0426] See Figure 10 , Figure 10 This is a flowchart of an information processing method provided in an embodiment of this application, applied to a network device, such as... Figure 10 As shown, it includes the following steps:

[0430] The indicated information can indicate different content.

[0431] For example, the indication information includes: the identifier of one or more PDCP protocol sublayer functional bodies in the control plane.

[0454] Indication for routing functionality in MAC protocol sublayer functionalities;

[0455] The transmission configuration parameters of the TNL corresponding to each DB.

[0456] The meaning of each parameter in the DB configuration information can be found in the corresponding description of the foregoing embodiments.

[0457] For example, the user plane higher-layer functional units include an L3UP protocol sublayer functional unit, and the user plane lower-layer functional units include: one or more SDAP protocol sublayer functional units, and / or, one or more MAC protocol sublayer functional units; or

[0458] The user plane higher-layer functional units include SDAP protocol sublayer functional units, and the user plane lower-layer functional units include one or more PDCP protocol sublayer functional units, and / or one or more MAC protocol sublayer functional units.

[0459] For example, the indication information is used to indicate the connection configuration relationship between one or more MAC protocol sublayer functional bodies and one or more RLC protocol sublayer functional bodies; and / or

[0460] The indication information is used to indicate the connection configuration relationship between one or more MAC protocol sublayer functional units and one or more PHY protocol sublayer functional units.

[0461] In this embodiment, the terminal can establish protocol sublayer functional bodies and / or set connection relationships between protocol sublayer functional bodies according to the indication information of the RRC signaling of the network device. Therefore, using the solution of this embodiment, even when there is a many-to-one or one-to-many relationship between inter-layer protocol sublayers, and the functional bodies of the same protocol stack sublayer are not unique, consistency between the sending end and the receiving end can be guaranteed, thereby reducing the overhead of end-to-end radio link control.
