[0002] In mobile communication systems, the wireless communication protocol stack is divided into the user plane protocol stack and the control plane protocol stack. The user plane protocol stack includes the physical (PHY) layer, the media access control (MAC) layer, the radio link control (RLC) layer, the packet data convergence protocol (PDCP) layer, and the service data adaptation protocol (SDAP) layer. The control plane protocol stack includes the PHY layer, the MAC layer, the RLC layer, the PDCP layer, and the radio resource control (RRC) layer.

[0003] From the perspective of the functions of each layer of the protocol stack, on the one hand, there is overlap or similarity between the functions of different protocol layers; on the other hand, the introduction of multiple protocol layers brings more interaction between the protocol layers, thereby increasing the difficulty and workload of protocol stack development, raising the development threshold of protocol stack, and resulting in high costs for communication equipment. Summary of the Invention

[0030] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0031] Figure 1 This is a schematic diagram of a traditional wireless communication protocol stack, such as... Figure 1As shown, the wireless communication protocol stack is divided into a user plane protocol stack and a control plane protocol stack. The user plane protocol stack includes the PHY layer, MAC layer, RLC layer, PDCP layer, and SDAP layer; the control plane protocol stack includes the PHY layer, MAC layer, RLC layer, PDCP layer, and RRC layer. The PHY layer belongs to Layer 1 (L1). The MAC layer, RLC layer, PDCP layer, and SDAP layer belong to L2 (i.e., the data link layer). L2 solves the communication problem between two nodes, shielding the physical layer and providing a data link connection for the network layer. It enables near-error-free data transmission over a potentially faulty physical connection. To ensure transmission reliability, wireless communication divides L2 into the MAC layer, RLC layer, PDCP layer, and SDAP layer, using these four protocol layers to accomplish the aforementioned tasks. The MAC layer primarily addresses the adaptation of higher-layer data transmission over the physical layer medium. The RLC layer handles the processing of higher-layer data packets to the size required by the MAC layer. The PDCP layer converts higher-layer IP data packets into protocol data packets for the mobile communication network. The SDAP layer, a newly introduced protocol layer in New Radio (NR), maps Quality of Service (QoS) streams to Data Radio Bearers (DRBs), facilitating the integration of application layer transmission requirements. The RRC layer, belonging to Layer 3 (the control layer), primarily configures and controls the other layers of the wireless network protocol stack.

[0032] Table 1 below lists the main functions of the MAC layer, RLC layer, PDCP layer, SDAP layer, and RRC layer:

[0033]

[0034]

[0035] Table 1: Functions of Protocol Layers in Traditional Protocol Stacks

[0036] From the perspective of the functions of each protocol layer, on the one hand, there is overlap or similarity between the functions of different layers. For example, HARQ in the MAC layer, ARQ in the RLC layer, and PDCP PDU retransmission in the PDCP layer have overlapping or similar functions (although the multiple retransmission mechanisms of different layers further improve the reliability of data transmission, in some latency-sensitive scenarios, multiple retransmissions exceed the latency requirements, and even if the transmission is correct, it is meaningless). Other examples include SDU multiplexing / demultiplexing in the MA layer, segmentation / reassembly in the RLC layer, duplicate and error detection in the RLC layer, and duplicate detection and data recovery in the PDCP layer, all of which have overlapping or similar functions. On the other hand, because the protocol stack introduces multiple protocol layers, it brings more interaction between protocol layers, such as the mapping between logical channels, transport channels, and physical channels, and the mapping between QoS flow, DRB, and logical channels.

[0037] To this end, the following technical solutions are proposed in the embodiments of this application. The technical solutions of the embodiments of this application propose a very simple protocol stack structure. On the one hand, the overlapping or similar functions or functions that achieve the same purpose between existing protocol layers are merged. On the other hand, multiple protocol layers are merged in terms of structure.

[0038] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The embodiments of this application include at least some of the following contents.

[0039] It should be noted that the protocol stack involved in the embodiments of this application can be applied to communication devices, which can be terminals, base stations, or other communication devices in access network architectures.

[0040] It should be noted that the protocol stack described in the embodiments of this application may be referred to as a wireless communication protocol stack or a cellular wireless communication protocol stack, etc.

[0041] It should be noted that the first protocol layer described in the embodiments of this application may be, but is not limited to, called the enhanced MAC (eMAC) layer. In the following text, the first protocol layer and the eMAC layer may be described interchangeably.

[0042] Figure 2 This is a schematic diagram of a simplified protocol stack provided in an embodiment of this application, as shown below. Figure 2 As shown, the protocol stack is divided into a user plane protocol stack and a control plane protocol stack. The user plane protocol stack includes a PHY layer and an eMAC layer, with the eMAC layer above the PHY layer. The control plane protocol stack includes a PHY layer, an eMAC layer, and an RRC layer, with the eMAC layer above the PHY layer and the RRC layer above the eMAC layer.

[0043] The PHY layer in this application embodiment has the same functions as the traditional PHY layer, including all or part of the following functions: data transmission of physical channels, multiplexing / demultiplexing, channel coding / decoding, modulation and demodulation, control plane physical processes, data plane physical processes, frequency and time synchronization, power control, measurement and reporting, multiple-input multiple-output (MIMO) processing, and radio frequency processing.

[0044] The functions of the eMAC layer in this application embodiment are derived by merging and / or simplifying the functions of the SDAP layer, PDCP layer, and RLC layer (corresponding to the user plane), or by merging and / or simplifying the functions of the PDCP layer, RLC layer, and MAC layer (corresponding to the control plane). Specifically, the eMAC layer includes all or part of the following functions: dynamic scheduling, HARQ or ARQ, SR / BSR, scheduling priority, physical channel mapping, segmentation and multiplexing, data deduplication detection (or duplicate packet detection), reordering, encryption and decryption, integrity protection and integrity verification, header compression and decompression, data copy transmission, etc., wherein header compression and decompression and data copy transmission are optional functions. Compared with the traditional MAC layer, the eMAC layer in this application embodiment has the following enhancements:

[0045] 1. Merging of retransmission mechanisms: The HARQ function of the traditional MAC layer, the ARQ function of the RLC layer, and the PDCPPDU retransmission function of the PDCP layer are merged, and only the HARQ or ARQ function is retained in the eMAC layer.

[0046] 2. Simplification of scheduling priorities: The traditional mapping between QoS flow, DRB, and logical channel priority is simplified in the eMAC layer to a mapping from QoS flow to scheduling priority. Alternatively, the eMAC layer can directly read the scheduling priority information in the packet header of the upper IP layer. Different scheduling priorities correspond to different priority queues. The eMAC layer puts the data into the corresponding priority queue for queuing and scheduling based on the obtained scheduling priority.

[0047] 3. Simplification of channel mapping: The traditional mapping between logical channel, transmission channel and physical channel is simplified in the eMAC layer to directly map data to the physical channel.

[0048] 4. Merging of duplicate detection functions: The duplicate detection functions of the traditional RLC layer and the PDCP layer are merged, and only one duplicate detection function is retained in the eMAC layer.

[0049] 5. Merging of other functions: Important functions such as reordering, encryption and decryption, integrity protection and integrity verification, header compression and decompression (optional), and data copying and transmission (optional) of the traditional PDCP layer are merged into the eMAC layer.

[0050] The RRC layer in this application embodiment includes all or part of the following functions: mobility management, QoS management, measurement management, and eMAC layer configuration management. Compared with the traditional RRC layer, the RRC layer in this application embodiment simplifies or eliminates the bearer management process because the bearer is canceled or weakened in the user plane; furthermore, if the terminal has no power-saving requirements, it can be simplified to a connection-only state, thereby simplifying or eliminating connection management and related idle-state measurement management.

[0051] Table 2 below shows the main functions of the eMAC layer and RRC layer in the embodiments of this application:

[0052]

[0053] Table 1: Functions of Protocol Layers in the Protocol Stack of This Application Embodiment

[0054] Based on the above Figure 2 The present application embodiment also provides a data / data stream (such as QoS stream) processing flow in the above protocol stack, which can ensure data processing efficiency.

[0055] The technical solution of this application embodiment proposes a simplified cellular wireless communication protocol stack, which merges similar functions or functions that achieve the same purpose between protocol layers, and simplifies the inter-layer mapping introduced by multi-layer division.

[0056] Figure 3 This is a flowchart illustrating a data processing method provided in an embodiment of this application. The data processing method is applied to a communication device, which has a first protocol stack. The first protocol stack can be as described above. Figure 2 The user plane protocol stack in the relevant description; such as Figure 3 As shown, the data processing method includes the following steps:

[0057] Step 301: The communication device processes the first data through the first protocol stack, and / or the communication device processes the second data through the first protocol stack; the first data is the data to be sent by the communication device, and the second data is the data received by the communication device; wherein, the first protocol stack includes a PHY layer and a first protocol layer, and the first protocol layer is located above the PHY layer.

[0058] In this embodiment of the application, the first protocol layer may be, but is not limited to, called the eMAC layer.

[0059] In this embodiment of the application, for the user plane, the functionality of the first protocol layer is obtained by merging and / or simplifying the functions of the SDAP layer, PDCP layer, RLC layer, and MAC layer. For the control plane, the functionality of the first protocol layer is obtained by merging and / or simplifying the functions of the PDCP layer, RLC layer, and MAC layer.

[0060] In this embodiment of the application, in the data transmission direction, according to the order of processing the first data, the first protocol layer sequentially includes some or all of the following functions: header compression function, serial number (SN) allocation function, data copying function, dynamic scheduling function, scheduling request (SR) function, buffer status report (BSR) function, segmentation and multiplexing function, integrity protection function, encryption function, physical channel mapping function, and HARQ or ARQ function.

[0061] In some implementations, during the process of the communication device processing the first data through the first protocol stack, the first processing and / or the second processing are performed before the third processing. The first processing is related to the dynamic scheduling function, the second processing is related to the data copying function, and the third processing is related to the encryption function.

[0062] In some implementations, the processing related to the above dynamic scheduling function includes at least one of the following:

[0063] Determine scheduling priorities;

[0064] Data is scheduled to the corresponding priority queue according to the scheduling priority.

[0065] Here, different scheduling priorities correspond to different priority queues, and data in higher priority queues are scheduled first compared to data in lower priority queues.

[0066] In some implementations, scheduling priorities can be determined in the following ways:

[0067] Method 1: Map QoS flows to scheduling priorities;

[0068] Method 2: Extract scheduling priority from IP packet header.

[0069] For the second method described above, the IP layer needs to include the scheduling priority information of the data in the IP packet header, so that the eMAC layer can extract the scheduling priority of the data from the IP packet header.

[0070] In the above scheme, in the data transmission direction, "encryption processing" is performed after "scheduling priority determination". "Encryption processing" corresponds to the third processing mentioned above, and "scheduling priority determination" corresponds to the first processing mentioned above.

[0071] It's important to note that, following the traditional protocol stack data processing flow, the PDCP layer first encrypts the data, making the priority information in the data packets invisible. Simultaneously, it's necessary to map the service priorities of the data packets, such as the QoS flow to DRB mapping performed at the SDAP layer, obtaining priority information from different bearers, thus increasing the processing flow. By merging the data encryption and decryption functions into the first protocol layer, the order of encryption processing and scheduling priority determination can be adjusted. First, the scheduling priority is determined based on the IP packet header, and then the data is placed into the corresponding priority queue based on the scheduling priority. Then, the data is encrypted. This process simplifies the data processing and allows for packet-by-packet scheduling priority determination based on the priority information in the IP packet header, providing a finer granularity for scheduling and guaranteeing priorities compared to the original limited number of DRB bearers.

[0072] In the above scheme, in the data transmission direction, the "data copying process" is performed before the "encryption process". The "encryption process" corresponds to the third process mentioned above, and the "data copying process" corresponds to the second process mentioned above.

[0073] It should be noted that the serial number (SN) of the data cannot be deciphered after encryption, making it impossible to accurately copy data with a specific SN. Therefore, it is necessary to copy the data based on the SN first, and then encrypt the data.

[0074] In some implementations, such as Figure 4 As shown, the first device processes the first data through the first protocol stack, which may include, but is not limited to, the following methods:

[0075] Method 1-1: The first device processes the first data sequentially through the first protocol stack as follows: assigning a sequence number (SN), header compression, integrity protection, scheduling processing, segmentation and multiplexing, encryption, and HARQ or ARQ processing.

[0076] Method 1-2: The first device processes the first data sequentially through the first protocol stack as follows: assigning a sequence number (SN), integrity protection, scheduling processing, segmentation and multiplexing, encryption, and HARQ or ARQ processing.

[0077] Methods 1-3: The first device processes the first data sequentially through the first protocol stack as follows: assigning a sequence number (SN), integrity protection, data copying (i.e., packet copying), scheduling, segmentation and multiplexing, encryption, and HARQ or ARQ processing.

[0078] In this embodiment of the application, in the data receiving direction, according to the order of processing the second data, the first protocol layer sequentially includes some or all of the following functions: HARQ or ARQ function, physical channel reverse mapping function, decryption function, integrity verification function, demultiplexing and reassembly function, data duplication detection function, reordering function, and header decompression function.

[0079] In some implementations, during the process of the communication device processing the second data through the first protocol stack, the fourth and / or fifth processing is performed after the sixth processing. The fourth processing is related to the duplicate detection function, the fifth processing is related to the reordering function, and the sixth processing is related to the decryption function.

[0080] In the above scheme, in the data receiving direction, the data "reordering" and "deduplication" are performed after the "decryption".

[0081] It should be noted that the serial number (SN) of the data can only be obtained after the data is decrypted. The SN can be used to accurately determine whether the data is in the correct order and thus reorder the data. The SN can also be used to accurately determine whether there is duplicate data and thus perform deduplication.

[0082] In some implementations, such as Figure 5 As shown, the first device processes the second data through the first protocol stack, which may include, but is not limited to, the following methods:

[0083] Method 2-1: The first device processes the second data sequentially through the first protocol stack as follows: HARQ or ARQ processing, decryption, demultiplexing and reassembly, integrity verification, reordering and deduplication, and header decompression.

[0084] Method 2-2: The first device processes the second data sequentially through the first protocol stack as follows: HARQ or ARQ processing, decryption, demultiplexing and reassembly, integrity verification, and reordering.

[0085] Method 2-3: The first device processes the second data sequentially through the first protocol stack as follows: HARQ or ARQ processing, decryption, demultiplexing and reassembly, integrity verification, reordering and deduplication.

[0086] The technical solution of this application proposes a new data processing flow. In the data transmission direction, on the one hand, the data scheduling priority is determined first, and then the data is encrypted; on the other hand, data is copied first, and then the data is encrypted. This processing method simplifies the QoS guarantee process. In the data reception direction, data is decrypted first, and then the data is reordered and / or deduplicated.

[0089] The second protocol stack includes a PHY layer, a first protocol layer, and a Radio Resource Control (RRC) layer. The first protocol layer is located above the PHY layer, and the RRC layer is located above the first protocol layer. The functions of the first protocol layer are obtained by merging and / or simplifying the functions of the PDCP layer, RLC layer, and MAC layer.

[0090] In some implementations, the first protocol layer includes some or all of the following functions: header compression, SN allocation, data replication, dynamic scheduling, SR, BSR, segmentation and multiplexing, integrity protection, encryption, physical channel mapping, HARQ or ARQ; and / or,

[0091] The first protocol layer includes some or all of the following functions: HARQ or ARQ function, physical channel reverse mapping function, decryption function, integrity verification function, demultiplexing and reassembly function, data duplication detection function, reordering function, and header decompression function.
