Wireless communication method, terminal device and network device

Abstract

Provided are a wireless communication method, a terminal device and a network device. The method comprises: a first protocol layer of a terminal device receiving first information from a second protocol layer of a network device, wherein the first information is used for carrying configuration information of the first protocol layer, and the second protocol layer is a peer protocol layer of the first protocol layer. In the embodiments of the present application, by means of first information, a second protocol layer of a network device can send to a first protocol layer of a terminal device configuration information of the first protocol layer, wherein the first protocol layer and the second protocol layer are peer protocol layers. In this way, after receiving the first information, the terminal device can directly deliver the first information to the first protocol layer for processing (for example, parsing) and perform configuration application. Compared with conventional configuration process processing methods (regardless of which protocol layer is configured by using the configuration information, configuration information of the protocol layer is required to be first delivered layer by layer to an RRC layer for processing, and the RRC layer then transfers the processed configuration information back to the configured protocol layer for configuration), the configuration method provided in the present application facilitates a reduction in the latency required for configuring parameters for a first protocol layer, thereby improving the efficiency of configuring the first protocol layer. Moreover, the configuration of each protocol layer is configured and managed by a peer protocol layer of each protocol layer, such that the dependence of a configuration process on an RRC protocol layer can be significantly reduced, thereby facilitating the implementation of a concise RRC protocol layer function.

Description

Method of wireless communication, terminal device and network device TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and more particularly, to a method of wireless communication, a terminal device and a network device. BACKGROUND

[0002] In a conventional access layer related configuration process, no matter which protocol layer the configuration information is configured for, the configuration information is transmitted through a radio resource control (RRC) message. That is to say, no matter which protocol layer the configuration information is configured for, the configuration information needs to be first processed by layer by layer (for example, sequentially passing through a physical layer (PHY), a media access control (MAC) layer, a radio link control (RLC) layer, a packet data convergence protocol (PDCP) layer, an RRC layer of a terminal device) to an RRC layer, and then the processed configuration information is transmitted back to the protocol layer (also referred to as a "first protocol layer") configured by the configuration information by the RRC layer. This centralized configuration based on the RRC layer is low in efficiency, resulting in a large delay required for configuring each protocol layer.

[0015] In the embodiments of the present application, the second protocol layer of the network device can configure the first protocol layer of the terminal device by the first information, wherein the first protocol layer and the second protocol layer are peer protocol layers. In this way, after receiving the first information, the terminal device can directly submit the first information to the first protocol layer for processing (for example, parsing) and configuration application. Compared with the traditional configuration process processing mode (regardless of the protocol layer to which the configuration information is configured, the configuration information of the protocol layer needs to be submitted to the RRC layer layer by layer for processing, and then the processed configuration information is transmitted back to the configured protocol layer for configuration), the configuration method provided in the present application can help to reduce the time delay required for configuring the parameters of the first protocol layer, so as to improve the efficiency of configuring the first protocol layer. On the other hand, the configuration of each protocol layer is configured and managed by the peer protocol layer of each protocol layer, which can significantly reduce the dependence of the configuration process on the RRC protocol layer, and is conducive to realizing a simple RRC protocol layer function.

[0052] It should be understood that all or part of the functions of the communication device in the present application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform).

[0053] Control plane protocol stack

[0054] As shown in FIG. 2, the control plane protocol stack in some communication systems (such as an NR system) can include one or more of the following: a non-access stratum (NAS) layer, an RRC layer, a PDCP layer, an RLC layer, a MAC layer and a PHY, and the functions of each protocol layer can be referred to the following introduction.

[0055] NAS layer: mainly responsible for the transmission and reception of control plane NAS messages.

[0056] RRC layer: mainly responsible for the transmission and reception of control plane signaling of each layer. For example, used to generate control instructions of RRC, control instructions of PDCP, control instructions of RLC, control instructions of MAC, and control instructions of PHY.

[0057] PDCP layer: mainly responsible for header compression / decompression, encryption / decryption, reordering and other functions of control plane data.

[0058] RLC layer: mainly responsible for segmentation / concatenation, automatic repeat request (ARQ) and other functions of control plane data.

[0059] MAC layer: mainly responsible for scheduling, multiplexing / demultiplexing, hybrid automatic repeat request (HARQ), random access procedure and other functions of control plane data.

[0060] PHY: mainly responsible for encoding / decoding, modulation / demodulation, transmission / reception and other functions of control plane data.

[0061] In some scenarios, if the network device adopts a CU and DU separation architecture, the DU is responsible for the functions of the RLC layer and the protocol layers below the RLC layer (i.e., the MAC and PHY protocol layers), and the CU is responsible for the related functions of the PDCP layer, the RRC layer and the NAS layer.

[0062] Introduction of configuration process of protocol layer

[0063] Currently, the network device configures the functional parameters of each protocol layer (e.g., a PHY protocol layer, a MAC protocol layer, an RLC protocol layer, a PDCP protocol layer, and an RRC protocol layer) for the terminal device through an RRC reconfiguration message, or in other words, the network device indicates the configuration information of each protocol layer for the terminal device through the RRC reconfiguration message. Since the configuration is performed by using the RRC message, all the functional parameters need to reach the RRC layer of the terminal device to be parsed, and then the configuration information parsed by the RRC layer is transmitted to the protocol layer configured by the configuration information through an interlayer interaction process for configuration.

[0064] As known from the foregoing description, in the conventional configuration process related to the access layer, the configuration information is transmitted through the RRC message regardless of the protocol layer configured by the configuration information. In other words, regardless of the protocol layer configured by the configuration information, the configuration information needs to be submitted to the RRC layer for processing through layer-by-layer submission (e.g., sequentially passing through the PHY, MAC, RLC, PDCP, and RRC layers of the terminal device), and then the processed configuration information is transmitted back to the protocol layer (also referred to as the first protocol layer) configured by the configuration information for configuration. This RRC layer centralized configuration mode is low in efficiency, resulting in a large time delay required for configuring each protocol layer. On the other hand, since all the access network configurations are first processed by the RRC protocol layer, the RRC protocol layer supports too complex functions.

[0065] For example, when the first protocol layer is the physical layer, after the physical layer of the terminal device first receives the information containing the RRC message, the physical layer needs to first submit the information containing the RRC message to the upper layer to the RRC layer for parsing, and then transmit the parsed configuration information from the RRC layer back to the physical layer for configuration. This RRC layer centralized configuration mode is low in efficiency, resulting in a large time delay required for configuring each protocol layer.

[0066] Therefore, to solve the above problems, the embodiment of the present application provides a method for wireless communication, in which a second protocol layer of a network device can configure a first protocol layer of a terminal device by first information, wherein the first protocol layer and the second protocol layer are peer protocol layers. In this way, after receiving the first information, the terminal device can directly submit the first information to the first protocol layer for processing (for example, parsing) and configuration application. Compared with the traditional configuration process processing mode (regardless of which protocol layer the configuration information of the protocol layer is configured for, the configuration information of the protocol layer needs to be submitted to the RRC layer layer by layer for processing, and then the processed configuration information is transmitted back to the protocol layer configured for configuration by the RRC layer), the configuration method provided by the present application can help to reduce the time delay required for configuring the parameters of the first protocol layer, so as to improve the efficiency of configuring the first protocol layer. On the other hand, the configuration of each protocol layer is configured and managed by the peer protocol layer of each protocol layer, which can significantly reduce the dependence of the configuration process on the RRC protocol layer, and is conducive to realizing a simple RRC protocol layer function.

[0067] On the other hand, in the embodiment of the present application, since each protocol layer processes the configuration information of the protocol layer itself, compared with the overall management of the configuration by the RRC protocol layer, it is more efficient, because in one configuration process, each protocol layer only needs to process the configuration related to the protocol layer, which is suitable for lightweight incremental configuration process.

[0068] In order to facilitate understanding, the method for wireless communication of the embodiment of the present application is introduced below in combination with FIG. 3. The method shown in FIG. 3 includes step S310.

[0069] In step S310, the first protocol layer of the terminal device receives the first information from the second protocol layer of the network device, and the first information is used to carry the configuration information of the first protocol layer, or in other words, the first information is used to configure the first protocol layer by the second protocol layer of the network device.

[0070] In some implementations, the first protocol layer is an access layer. In other implementations, the first protocol layer can include one or more of the following: a PHY layer, a MAC layer, an RLC layer, a PDCP layer, and a protocol layer in a 6G network.

[0071] It should be particularly pointed out that the protocol layer in the 6G network can be a new protocol layer (for example, a third protocol layer) introduced by the 6G or next generation communication system in the air interface. Or in other words, the protocol layer in the 6G network can be a protocol layer obtained by merging the functions of multiple protocol layers (for example, two or three protocol layers) in a known communication system, (for example, the protocol layer in the 6G network can be a protocol layer obtained by merging the functions of the PDCP protocol layer and the RLC protocol layer, etc. At this time, the above step S310 includes: the protocol layer in the 6G network of the terminal device receiving first information from the protocol layer in the 6G network of the network device, the first information including configuration information of the protocol layer in the 6G network.

[0072] In some implementations, the second protocol layer is a peer protocol layer of the first protocol layer. For example, if the first protocol layer is PHY, the second protocol layer is PHY. For another example, if the first protocol layer is the MAC layer, the second protocol layer is the MAC layer. For another example, if the first protocol layer is the RLC layer, the second protocol layer is the RLC layer. For another example, if the first protocol layer is the PDCP layer, the second protocol layer is the PDCP layer.

[0073] That is to say, the configuration of each protocol layer (here referring to PHY, MAC layer, RLC layer or PDCP layer) of the terminal device is based on the first information sent by the peer protocol layer of the network device. For example, the PHY-related configuration of the terminal device is based on the first information sent by the physical layer of the network device. For another example, the MAC layer-related configuration of the terminal device is based on the first information sent by the MAC layer of the network device. For another example, the RLC layer-related configuration of the terminal device is based on the first information sent by the RLC layer of the network device. For another example, the PDCP layer-related configuration of the terminal device is based on the first information sent by the PDCP layer of the network device.

[0074] It should be emphasized that the above-mentioned reception of the first information by the first protocol layer of the terminal device means that the target protocol layer of the first information is logically the first protocol layer, and from the perspective of the air interface, the information containing the first information still needs to be received through the physical layer of the terminal device, and after the physical layer of the terminal device successfully receives the information containing the first information, it is determined whether to further submit to the upper protocol layer according to the control process, until the target protocol layer (i.e. the first protocol layer) of the first information is determined.

[0075] As described above, the first protocol layer can include one or more of the PHY layer, the MAC layer, the RLC layer, and the PDCP layer.

[0076] The first information in the embodiments of the present application will be described below in conjunction with Embodiments 1-4.

[0077] Embodiment 1: The first protocol layer is a PHY layer.

[0078] In the embodiments of the present application, the PHY layer of the network device can configure the PHY layer of the terminal device through the first information. In this way, after receiving the first information, the terminal device can directly submit the first information to the PHY layer for processing (e.g., parsing) and configuration application. Compared with the traditional configuration process processing mode (regardless of the protocol layer to which the configuration information is configured, the configuration information of the protocol layer needs to be submitted layer by layer to the RRC layer for processing, and then the processed configuration information is transmitted back to the configured protocol layer for configuration), the configuration method provided in the present application can help to reduce the time delay required for configuring the PHY layer parameters, thereby improving the efficiency of configuring the PHY layer. On the other hand, the configuration of the PHY layer in the terminal device is configured and managed by the PHY layer in the network device, which can significantly reduce the dependence of the configuration process on the RRC protocol layer, and is conducive to realizing a simple RRC protocol layer function.

[0079] In some implementations, the first information includes first indication information and / or second information, wherein the first indication information is used to indicate the PHY layer control information type, and the second information is used to carry the PHY configuration information.

[0080] In some implementations, the first information can be transmitted through a physical downlink shared channel (e.g., PDSCH).

[0081] Taking the first information including the second information as an example, in some implementations, the second information can include the control information of the PHY, and accordingly, the control information of the PHY can include the configuration information of the PHY.

[0082] In the embodiments of the present application, the configuration information of the PHY is not limited. In some implementations, the configuration information of the PHY can include one or more of the following: MIMO function related configuration, random access function related configuration, power related configuration, filtering related configuration, transmission configuration indication (TCI) related configuration, physical downlink shared channel (PDSCH) related configuration, physical downlink control channel (PDCCH) related configuration, physical uplink control channel (PUCCH) related configuration, and physical uplink shared channel (PUSCH) related configuration.

[0083] In some implementations, the physical layer configuration information is used to control the physical layer function, which can be directly applied by the physical layer after being parsed by the physical layer, for example: MIMO function related configuration parameters, without the need to use the configuration provided additionally by the RRC protocol layer. In the conventional technology, the physical layer cannot directly parse the physical layer configuration information, and all the physical layer configuration information is parsed by the RRC protocol layer and then transmitted to the physical layer through the interlayer interaction process. Although the DCI of the physical layer can also be used to control the activation or deactivation of some configurations, the control information contained in the DCI is mostly the index (index) of the RRC transmission configuration, and is not the configuration information itself. For example, BWP ID, TCI state ID, RO mask ID, and the physical layer of the terminal device will determine which configuration delivered by the RRC needs to be activated or deactivated according to the index contained in the DCI, which is essentially different from the configuration information of the embodiments of the present application.

[0084] In some implementations, the second information further includes message type indication information and / or group indication information, which helps the terminal device to confirm the format used to decode the configuration information of the PHY carried in the second information. In addition, the second information including the message type indication information and / or the group indication information can further increase the flexibility of the configuration, for example, a small number of parameters can be configured by the message type indication information and / or the group indication information to keep most of the parameters from being reconfigured, thereby saving the overhead of the reconfiguration process.

[0085] In some embodiments, the second information includes message type indication information, which is used to indicate a message type to which the PHY configuration information included in the second information belongs, or in other words, which is used to indicate which kind of physical layer message the PHY control information included in the second information belongs to. In the embodiments of the present application, the implementation of the message type indication information is not limited. In some embodiments, the message type indication information can be implemented by a choice function or identification information indication.

[0086] In some embodiments, different values of the message type indication information can correspond to different message types. For example, the PHY configuration information can be divided into 5 message types, at this time, the message type indication information can occupy 3 bits, and each message type corresponds to a value, i.e., message type 1 corresponds to value '000', message type 2 corresponds to value '001', message type 3 corresponds to value '010', message type 4 corresponds to value '011', and message type 5 corresponds to value '100'.

[0087] In the embodiments of the present application, the number of bits occupied by the message type indication information is not limited. For example, the message type indication information can occupy 3 bits. For another example, the message type indication information can occupy 2 bits. In addition, in the embodiments of the present application, the content included in different message types can be predefined.

[0088] In some embodiments, the second information includes group indication information, which is used to indicate a parameter group to which the PHY configuration information included in the second information belongs, or in other words, which is used to indicate which group of parameters is intended to be configured in the current configuration process. In the embodiments of the present application, the implementation of the group indication information is not limited. In some embodiments, the group indication information can be implemented by a choice function or identification information indication.

[0089] In some embodiments, different values of the group indication information can correspond to different parameter groups. For example, the PHY configuration information can be divided into 6 groups, at this time, the group indication information can occupy 3 bits, and each group of configuration information corresponds to a value, i.e., group 1 corresponds to value '000', group 2 corresponds to value '001', group 3 corresponds to value '010', group 4 corresponds to value '011', and group 5 corresponds to value '100'.

[0090] In the embodiments of the present application, the number of bits occupied by the group indication information is not limited. For example, the group indication information can occupy 3 bits. For another example, the group indication information can occupy 2 bits. In addition, in the embodiments of the present application, the content included in different groups can be predefined.

[0091] In some other implementations, the second information includes message type indication information and group indication information. The message type indication information and the group indication information are described in other implementations, and thus will not be described here.

[0092] In the embodiments of the present application, the implementation of the second information is not limited. The following describes Examples 1-1 to 1-4. It should be understood that the following mainly describes the implementation of the second information, and the meaning of the information included in the second information can be referred to the description above.

[0093] Example 1-1: The second information includes physical layer configuration information.

[0094] Example 1-2: The second information includes message type indication information and physical layer configuration information, wherein the message type indication information is used to indicate which type of message the current configuration process intends to configure.

[0095] For example, the physical layer defines two types of messages: a first type of message and a second type of message. In order to let the terminal device know the PHY configuration information of the current configuration, the second information can carry the message type indication information, i.e., the message type indication information indicates that the PHY configuration information of the current configuration is the parameter in the first type of message.

[0096] Example 1-3: The second information includes group indication information and physical layer configuration information, wherein the group indication information is used to indicate which group of parameters the current configuration process configures.

[0097] For example, the physical layer defines two groups of parameters. In order to let the terminal device know the PHY configuration information of the current configuration, the second information can carry the group indication information, i.e., the group indication information can be used to indicate that the PHY configuration information of the current configuration is the first group of parameters.

[0098] Example 1-4: The second information includes message type indication information, group indication information and physical layer configuration information, wherein the message type indication information is used to indicate which type of message the group of parameters the current configuration process intends to configure belongs to, and the group indication information is used to indicate which group of parameters in the message the current configuration process intends to configure.

[0099] For example, the physical layer defines two types of messages, wherein the first type of message includes two groups of parameters, and the second type of message includes three groups of parameters. In order to let the terminal device know the PHY configuration information of the current configuration, the second information can carry the message type indication information and the group indication information, i.e., the message type indication information and the group indication information indicate that the PHY configuration information of the current configuration is the first group of parameters in the first type of message.

[0100] The second information in the embodiments of the present application is introduced above, and the first indication information in the embodiments of the present application is introduced below.

[0101] Taking the first information including the first indication information as an example, when the value of the first indication information is a first value, the first information further includes the second information, and at this time, the PHY layer control information type indicated by the first indication information is control information containing the configuration information of the PHY.

[0102] In the embodiments of the present application, the value of the first value is not limited. Taking the first value as '000' as an example, when the value of the first indication information is '000', the PHY layer control information type indicated by the first indication information is control information containing the configuration information of the PHY. Of course, in the embodiments of the present application, the value of the first value can also be '001' and the like.

[0103] In some implementations, the value of the first value can be predefined. For example, the value of the first value can be predefined through a protocol.

[0104] In other implementations, when the value of the first indication information is a fifth value, the first information does not include the second information, and at this time, the PHY layer control information type indicated by the first indication information is control information not containing the configuration information of the PHY, for example, the first information contains control instructions for activating or deactivating a configuration, and these configurations are obtained in advance by the terminal device (such as through the first information sent previously), at this time, the control instructions contained in the first information can be implemented through an index or a bit map of the configuration (one or several bits in the bit map are associated with a configuration or a group of configurations), but the control instructions themselves cannot be considered as physical layer configuration parameters, but should be considered as actions or instructions related to the physical layer configuration parameters (such as the activation and deactivation actions of the BWP, the instructions for triggering the non-contention-based random access process, and the like).

[0105] In the embodiments of the present application, the value of the fifth value is not limited, wherein the fifth value is different from the first value. Taking the fifth value as '010' as an example, when the value of the first indication information is '010', the PHY layer control information type indicated by the first indication information is control information not containing the configuration information of the PHY. Of course, in the embodiments of the present application, the value of the fifth value can also be '011' and the like.

[0106] In some implementations, the value of the fifth value can be predefined. For example, the value of the fifth value can be predefined through a protocol.

[0107] In some implementations, there is a one-to-one correspondence between the value of the first indication information and the PHY layer control information type.

[0108] In some embodiments, the first indication information can be carried by a PHY layer control information type field. FIG. 4 shows an example of this embodiment.

[0109] In some embodiments, the first information further comprises segment indication information and / or first length indication information. For example, the first information further comprises segment indication information and first length indication information. For another example, the first information can further comprise segment indication information. For yet another example, the first information can further comprise first length indication information.

[0110] Taking the first information comprising first length indication information as an example, in some embodiments, the first length indication information is used to indicate the length of the second information, which helps to realize the provision of at least two kinds of PHY layer control information with different lengths by the first information. For example, through the flexible indication of the first length indication information, it can be determined that the first information can only contain the second information, or the first information can contain the second information and other physical layer control information at the same time. Compared with the method without the first length indication information, the indication of the first information comprising the first length indication information in the embodiment of the present application is more flexible.

[0111] For example, the first length indication information is used to indicate the number of bytes occupied by the second information. For another example, the first length indication information is used to indicate the number of bits occupied by the second information.

[0112] In some embodiments, the first length indication information can be carried by an L field. FIG. 5 shows an example of this embodiment.

[0113] In some embodiments, the first information further comprises second length indication information, which is used to indicate the length of the first length indication information, which helps to improve the flexibility of setting the length occupied by the first length indication information. For example, the second length indication information is used to indicate the number of bytes occupied by the first length indication information. For another example, the second length indication information is used to indicate the number of bits occupied by the first length indication information.

[0114] In the embodiment of the present application, the manner in which the second length indication information indicates the length of the first length indication information is not limited. In some embodiments, the second length indication information can directly carry the actual length information of the first length indication information. In other embodiments, the value of the second length indication information can correspond to the actual length of the first length indication information one by one. For example, when the value of the second length indication information is ‘1’, it can be agreed by the protocol that the first length indication information occupies 19 bits. For another example, when the value of the second length indication information is ‘0’, it can be agreed by the protocol that the first length indication information occupies 11 bits.

[0115] In some embodiments, the second length indication information can be carried by an F field. FIG. 6 shows an example of this embodiment.

[0116] In some implementations, the length of the first length indication information is predefined, which helps to reduce the number of bits for transmitting the first information. For example, the length of the first length indication information is agreed to occupy 47 bits in the protocol. For another example, the length of the first length indication information is agreed to occupy 12 bits in the protocol. For another example, the length of the first length indication information is agreed to occupy 15 bits in the protocol. For another example, the length of the first length indication information is agreed to occupy 20 bits in the protocol.

[0117] In some implementations, the length of the first length indication information is configured by the network device, which helps to improve the flexibility of setting the length of the first length indication information. For example, the network device can configure the length of the first length indication information through dedicated signaling. For another example, the network device can configure the length of the first length indication information to occupy 4 bits through dedicated signaling. For another example, the network device can configure the length of the first length indication information to occupy 12 bits through dedicated signaling. For another example, the network device can configure the length of the first length indication information to occupy 18 bits through dedicated signaling. For another example, the network device can configure the length of the first length indication information to occupy 20 bits through dedicated signaling.

[0118] Taking an example that the first information includes segmentation indication information, in some implementations, the segmentation indication information is used to indicate the first state corresponding to the information contained in the second information, which helps to improve the flexibility of the configuration process. Generally, considering that the information capacity of a single first information is limited, if a piece of first information cannot carry all the configuration information provided in the current reconfiguration process, the segmentation indication information can be introduced into the first information to realize the segmented reception and recombination of the configuration information.

[0119] In some implementations, the segmentation indication information, also referred to as segmentation information (SI), can be carried in the SI field. The following will be introduced in combination with FIG. 7A and FIG. 7B.

[0120] In some implementations, the first state is used to indicate one or more of the following: the second information carries complete configuration information; the second information carries the first segment of the complete configuration information; the second information carries the last segment of the complete configuration information; and the second information carries an intermediate segment of the complete configuration information, where the intermediate segment can be understood as a segment other than the first segment and the last segment among the multiple segments corresponding to the complete configuration information.

[0121] It is emphasized that the complete configuration information herein is a relative concept. For example, the physical layer of the network device this time prepares 1000 bits of parameters for the physical layer configuration of the terminal device, and thus the 1000 bits transmitted this time can be considered as the complete configuration information. Next time, the physical layer of the network device prepares 1200 bits of parameters for the physical layer configuration of the terminal device, and thus the 1200 bits transmitted next time can be considered as the complete configuration information. If a piece of first information cannot transmit the complete configuration information, the complete configuration information needs to be segmented and transmitted. Each configuration segment is carried by a piece of first information. According to the segmentation, the complete configuration information can be transmitted by one or more pieces of first information.

[0122] For example, the physical layer configuration information included in the second information can be transmitted by a physical layer transmission block (TB). The first state is used to indicate one of the following: the transmission block carrying the second information is a transmission block carrying the complete configuration information, the transmission block carrying the second information is the first transmission block in a plurality of transmission blocks carrying the complete configuration information, the transmission block carrying the second information is the last transmission block in the plurality of transmission blocks carrying the complete configuration information, and the transmission block carrying the second information is a middle transmission block in the plurality of transmission blocks carrying the complete configuration information.

[0123] In some implementations, if the first state indicated by the segmentation indication information is that the second information carries a middle segment of the complete configuration information, the first information further includes segment offset indication information, which is referred to as segment offset (SO) for short.

[0124] In some implementations, the SO is used to indicate the byte number (which can be a logical number or an actual number) of the first byte in the configuration information carried by the second information in the complete PHY configuration information. For example, the SO is used to indicate a first offset, which is the offset value between the logical number corresponding to the first byte in the configuration information carried by the second information and the logical number corresponding to the first byte in the complete PHY configuration information, or in other words, the first offset is the number of bytes between the logical number corresponding to the first byte (or the first byte data) in the configuration information carried by the second information and the logical number corresponding to the first byte (or the first byte data) in the complete PHY configuration information.

[0125] It should be understood that in the embodiments of the present application, the logical number can correspond to a plurality of actual byte numbers in the complete PHY configuration information, which helps to reduce the number of bits of the information carried in the SO field. For example, the actual byte numbers of the complete PHY configuration information include 1000 bytes, the logical number 0 can correspond to the actual byte numbers 0-299, the logical number 1 can correspond to the actual byte numbers 300-699, and the logical number 2 can correspond to the actual byte numbers 700-999. When the second physical layer transport block segment is transmitted, the value of the SO field in the first information is 1.

[0126] Of course, in the embodiments of the present application, the logical number can also one-to-one correspond to the actual byte numbers of the complete PHY configuration information, which helps to simplify the mapping relationship between the logical number and the actual byte number. For example, a complete PHY configuration information contains 1000 actual bytes (the actual byte numbers of the complete PHY configuration information are 0-999 in turn, and the actual byte number starts from 0), which is divided into 3 physical layer transport blocks for transmission, the first physical layer transport block occupies 300 actual bytes (the actual byte numbers of the information contained in the first physical layer transport block are 0-299 in turn), the second physical layer transport block occupies 400 actual bytes (the actual byte numbers of the information contained in the second physical layer transport block are 300-699 in turn), and the third physical layer transport block occupies 300 actual bytes (the actual byte numbers of the information contained in the third physical layer transport block are 700-999 in turn). When the second physical layer transport block segment is transmitted, the value of the SO field in the first information is 300.

[0127] It should be noted that the actual byte number here can also be regarded as a kind of logical number, which is used to indicate the logical sequence relationship of the data before and after the data, and the information is convenient for the data receiver to recombine the segmented data, and does not represent the actual address number of the computer storing the data.

[0128] In the embodiments of the present application, the representation of the four meanings of the first state is not limited. In some implementations, ‘00’, ‘01’, ‘10’ and ‘11’ can be used in turn to represent the four meanings of the first state.

[0129] In some implementations, the first information can further include fifth indication information, wherein the fifth indication information is used to indicate whether the information carried by the first information is data type information or control type information.

[0130] In some implementations, the fifth indication information can be carried in a data / control (D / C) field, which will be described below in conjunction with FIG. 4.

[0131] In some embodiments, if the fifth indication information indicates that the information carried by the first information is data type information, it means that the first information does not include the second information, or in other words, the payload contained in the first information does not need to be parsed by the PHY. It should be understood that in the embodiments of the present application, if the fifth indication information indicates that the information carried by the first information is data type information, the first information can carry application layer data type information or carry configuration information and / or non-configuration type control instructions of other protocol layers (for example, MAC layer, RLC layer, PDCP layer, etc.).

[0132] In some embodiments, if the fifth indication information indicates that the information carried by the first information is data type information, the method further includes: the PHY of the terminal device delivers the information in the first information that cannot be parsed by the physical layer to the MAC layer of the terminal device for processing.

[0133] In other embodiments, if the fifth indication information indicates that the information carried by the first information is control type information, the first information can include the second information. At this time, it can be further determined whether the PHY layer control information type is control information containing the configuration information of the PHY based on the value of the first indication information. That is, in this way, the first information can include the fifth indication information and the first indication information. Of course, in the embodiments of the present application, if the fifth indication information indicates that the information carried by the first information is control type information, the first information includes the second information. At this time, it can be considered that the PHY layer control information type only exists in the control information containing the configuration information of the PHY. That is, in this way, the first information can include the fifth indication information and does not include the first indication information.

[0134] In some embodiments, the fifth indication information can also be included in the physical downlink control channel (at this time, the first information carried by the physical downlink shared channel does not include the fifth indication information), wherein the fifth indication information is used to indicate whether the information carried by the first information is data type information or control type information. If the fifth indication information indicates that the information carried by the first information is data type information, the method further includes: the PHY of the terminal device delivers all the information of the first information to the MAC layer of the terminal device for processing. In other embodiments, if the fifth indication information indicates that the information carried by the first information is control type information, the first information can include the second information, at this time, it can be further determined whether the PHY layer control information type is control information containing the configuration information of the PHY based on the value of the first indication information, of course, if the physical layer only has one kind of control information (i.e. control information containing the configuration information of the physical layer), the first information can not include the first indication information, at this time, the first information includes the second information.

[0135] For the convenience of understanding, the first information in the embodiments of the present application is introduced below in combination with Examples 1-5 to 1-11. It is assumed that Oct represents a byte, and one byte occupies 8 bits. It should be understood that the following mainly introduces the carrying manner of the first information, and the meaning of the information contained in the first information can be referred to the introduction above.

[0136] Example 1-5: When the first indication information takes the first value, the first information at least includes the first indication information and the second information. Optionally, the first information can further include the fifth indication information. The format of the physical layer TB in the embodiments of the present application is introduced below in combination with FIG. 4 by taking the example that the first information is transmitted through the physical layer TB.

[0137] Referring to FIG. 4, the TB can include a D / C field, a PHY layer control information type field and a field for carrying the second information. The D / C field can occupy the first bit in Oct1, the PHY layer control information type field can occupy the second to fourth bits in Oct1, and the field for carrying the second information can occupy the remaining bits in Oct1 and all bits in Oct2-OctN (N is a positive integer greater than or equal to 2).

[0138] Correspondingly, the D / C field is used to carry the fifth indication information, the PHY layer control information type field is used to carry the first indication information, and the first indication information is used to indicate whether the PHY layer control information type is control information containing the PHY configuration information. For example, if the PHY layer control information type field takes the first value, it indicates that the current processing PHY transport block contains the PHY configuration information, and conversely, if the PHY layer control information type field takes the fifth value, it indicates that the current processing PHY transport block does not contain the PHY configuration information.

[0139] It should be noted that in some scenarios, the last several bits (for example, 2 bits, 3 bits, 4 bits, etc.) of the D / C field can be a reserved field (i.e., R field), and at this time, the first information can include the first indication information, the reserved information field, the fifth indication information and the second information.

[0140] Example 1-6: When the first indication information takes the first value, the first information at least includes the first indication information, the first length indication information and the second information. Optionally, the first information can further include the fifth indication information. It should be noted that the length of the above-mentioned first length indication information can be pre-defined by a protocol or configured in advance to the terminal device by a network device through dedicated signaling.

[0141] The following describes the format of the physical layer TB in the embodiments of the present application by taking, as an example, the transmission of the first information through the physical layer TB in combination with FIG. 5. Referring to FIG. 5, the TB can include a D / C field, a PHY layer control information type field, an L field, and a field for carrying the second information. The D / C field can occupy the first bit in Oct1, the PHY layer control information type field can occupy the second to fourth bits in Oct1, the L field can occupy the remaining bits in Oct1 and all bits in Oct2, and the field for carrying the second information can occupy all bits in Oct3-OctN (N is a positive integer greater than or equal to 3).

[0142] Correspondingly, the D / C field is used to carry the fifth indication information, the L field is used to carry the first length indication information, and the PHY layer control information type field is used to carry the first indication information, which is used to indicate whether the PHY layer control information type is control information containing the PHY configuration information. For example, if the PHY layer control information type field takes the first value, it indicates that the current processing PHY transport block contains the PHY configuration information, and conversely, if the PHY layer control information type field takes the fifth value, it indicates that the current processing PHY transport block does not contain the PHY configuration information.

[0143] In some scenarios, the last several bits (for example, 2 bits, 3 bits, 4 bits, etc.) of the D / C field can be a reserved field (i.e., R field), and in this case, the first information can include the first indication information, the first length indication information, the reserved information field, the fifth indication information, and the second information.

[0144] Example 1-7: When the first indication information takes the first value, the first information at least includes the first indication information, the second length indication information, the first length indication information, and the second information. Optionally, the first information can also include the fifth indication information. It should be noted that the length of the first length indication information can be pre-defined by a protocol or configured in advance to the terminal device by the network device through dedicated signaling. The length of the second length indication information can be pre-defined by a protocol or configured in advance to the terminal device by the network device through dedicated signaling.

[0145] The following describes the format of the physical layer TB in the embodiments of the present application by taking, as an example, the transmission of the first information through the physical layer TB in combination with FIG. 6.

[0146] Referring to FIG. 6, the TB can include a D / C field, a PHY layer control information type field, an L field, an F field, and a field for carrying second information. The D / C field can occupy the first bit in Oct1, the PHY layer control information type field can occupy the second to fourth bits in Oct1, the F field can occupy the fifth bit in Oct1, the L field can occupy the remaining bits in Oct1 and all bits in Oct2, and the field for carrying second information can occupy all bits in Oct3-OctN (N is a positive integer greater than or equal to 3).

[0147] Correspondingly, the D / C field is used to carry the fifth indication information, the F field is used to carry the second length indication information, the L field is used to carry the first length indication information, and the PHY layer control information type field is used to carry the first indication information.

[0148] The first indication information is used to indicate whether the PHY layer control information type is control information containing PHY configuration information. For example, if the PHY layer control information type field takes a first value, it indicates that the current processing PHY transport block contains PHY configuration information, and conversely, if the PHY layer control information type field takes a fifth value, it indicates that the current processing PHY transport block does not contain PHY configuration information.

[0149] The second length indication information is used to indicate the length of the first length indication information, which can be understood as indicating the number of bits contained in the L field. For example, when the F field takes a value of '1', the L field occupies 19 bits. For another example, when the F field takes a value of '0', the L field occupies 11 bits.

[0150] In some scenarios, the last several bits (for example, 2 bits, 3 bits, 4 bits, etc.) of the D / C field can be a reserved field (i.e., R field). In other scenarios, the last several bits (for example, the last 2 bits) of the F field can be a reserved field (i.e., R field). In other scenarios, the last several bits (for example, the last 2 bits) of the PHY layer control information type field can be a reserved field (i.e., R field), and in this case, the first information can include the fifth indication information, the first indication information, the first length indication information, the second length indication information, the reserved information, and the second information.

[0151] Example 1-8: When the first indication information takes a first value, the first information includes the first indication information, the segmentation indication information, and the second information. Optionally, the first information can also include the fifth indication information. In some scenarios, the first information can also include the SO. Hereinafter, taking the transmission of the first information through the physical layer TB as an example, the format of the physical layer TB in the embodiments of the present application is introduced in combination with FIG. 7A and FIG. 7B.

[0152] Referring to FIG. 7A, the TB can include a D / C field, a PHY layer control information type field, an SI field, and a field for carrying second information. The D / C field can occupy the first bit in Oct 1, the PHY layer control information type field can occupy the second to fourth bits in Oct 1, the SI field can occupy the fifth and sixth bits in Oct 1, and the field for carrying second information can occupy the remaining bits in Oct 1 and all bits in Oct 2 to Oct N (N is a positive integer greater than or equal to 2).

[0153] Accordingly, the D / C field is used to carry the fifth indication information, the SI field is used to carry the segmentation indication information, and the PHY layer control information type field is used to carry the first indication information.

[0154] In some scenarios, if the SI field indicates that the current physical layer TB carries any one of the following: complete PHY configuration information, the first segment of complete PHY configuration information, and the last segment of complete PHY configuration information, the structure of the current physical layer TB can be as shown in FIG. 7A, and accordingly, the terminal device can decode according to the format shown in FIG. 7A.

[0155] Referring to FIG. 7B, the TB can include a D / C field, a PHY layer control information type field, an SI field, an SO field, and a field for carrying second information. The D / C field can occupy the first bit in Oct 1, the PHY layer control information type field can occupy the second to fourth bits in Oct 1, the SI field can occupy the fifth and sixth bits in Oct 1, at this time, the remaining bits in Oct 1 are used as a reserved field (R field). The SO field occupies Oct 2 to Oct 3, and the field for carrying second information can occupy all bits in Oct 4 to Oct N (N is a positive integer greater than or equal to 4).

[0156] Accordingly, the D / C field is used to carry the fifth indication information, the SI field is used to carry the segmentation indication information, the SO field is used to carry the segment offset indication information, and the PHY layer control information type field is used to carry the first indication information.

[0157] In some scenarios, if the SI field indicates that the current physical layer TB carries a middle segment of complete PHY configuration information, the structure of the current physical layer TB can be as shown in FIG. 7B, and accordingly, the terminal device can decode according to the format shown in FIG. 7B.

[0158] In some scenarios, the last several bits (e.g., 2 bits, 3 bits, 4 bits, etc.) of the D / C field can be a reserved field (i.e., R field). In some other scenarios, the last several bits (e.g., the last 2 bits) of the PHY layer control information type field can be a reserved field (i.e., R field). In some other scenarios, the last several bits (e.g., the last 2 bits) of the SI field can be a reserved field (i.e., R field), e.g., continuing to refer to FIG. 7B, the last 2 bits of the SI field can be a R field. In the above cases, the first information can include the fifth indication information, the first indication information, the SI, the reserved information, and the second information. Optionally, the first information can further include the SO field.

[0159] It should be noted that the position relationship between the SI field and the SO field is only exemplarily illustrated in FIG. 7B, and the embodiments of the present application do not limit this. For example, the SI field can occupy a plurality of bits, and the last several bits (e.g., 2 bits) of the plurality of bits can be used as the SO field.

[0160] Example 1-9: When the value of the first indication information is the first value, the first information includes the first indication information, the segmentation indication information, the first length indication information, and the second information. Optionally, the first information can further include the fifth indication information. In some scenarios, the first information can further include the SO field. It should be noted that the length of the first length indication information can be pre-defined by a protocol or configured to the terminal device in advance by a network device through dedicated signaling.

[0161] In the following, the format of the physical layer TB is introduced by taking the transmission of the first information through the physical layer TB as an example in combination with FIG. 8A and FIG. 8B.

[0162] Referring to FIG. 8A, the TB can include a D / C field, a PHY layer control information type field, an SI field, an L field, and a field for carrying the second information. The D / C field can occupy the first bit in Oct1, the PHY layer control information type field can occupy the second to fourth bits in Oct1, the SI field can occupy the fifth to sixth bits in Oct1, the L field occupies the remaining bits in Oct1 and all bits in Oct2, and the field for carrying the second information can occupy all bits in Oct3- OctN (N is a positive integer greater than or equal to 3).

[0163] Correspondingly, the D / C field is used to carry the fifth indication information, the SI field is used to carry the segmentation indication information, the L field is used to carry the first length indication information, and the PHY layer control information type field is used to carry the first indication information.

[0164] In some scenarios, if the SI field indicates that the current physical layer TB carries any of the following: complete PHY configuration information, the first segment of complete PHY configuration information, the last segment of complete PHY configuration information, the structure of the current physical layer TB can be seen from FIG. 8A, and accordingly, the terminal device can decode according to the format shown in FIG. 8A.

[0165] Referring to FIG. 8B, the TB can include a D / C field, a PHY layer control information type field, an SI field, an SO field, an L field, and a field for carrying second information. Among them, the D / C field can occupy the first bit in Oct1, the PHY layer control information type field can occupy the second to fourth bits in Oct1, the SI field can occupy the fifth to sixth bits in Oct1, at this time, the remaining bits in Oct1 are used as a reserved field (R field). The SO field occupies Oct2-Oct3, the L field occupies Oct4-Oct5, and the field for carrying second information can occupy all bits in Oct6-OctN (N is a positive integer greater than or equal to 6).

[0166] Accordingly, the D / C field is used to carry the fifth indication information, the SI field is used to carry the segment indication information, the SO field is used to carry the segment offset information, the L field is used to carry the first length indication information, and the PHY layer control information type field is used to carry the first indication information.

[0167] In some scenarios, if the SI field indicates that the current physical layer TB carries an intermediate segment of complete PHY configuration information, the structure of the current physical layer TB can be seen from FIG. 8B, and accordingly, the terminal device can decode according to the format shown in FIG. 8B.

[0168] In some scenarios, the last several bits (for example, 2 bits, 3 bits, 4 bits, etc.) of the D / C field can be a reserved field (i.e., R field). In other scenarios, the last several bits (for example, the last 2 bits) of the PHY layer control information type field can be a reserved field (i.e., R field). In other scenarios, the last several bits (for example, the last 2 bits) of the SI field can be a reserved field (i.e., R field), for example, continuing to refer to FIG. 8B, the last 2 bits of the SI field can be an R field. In the above case, the first information can include the fifth indication information, the first indication information, the SI, the reserved information, and the second information. Alternatively, the first information can also include the SO.

[0169] In addition, the position relationship between the SI field and the SO field in FIG. 8B is only illustrative, and the embodiments of the present application do not limit this. For example, the last several bits (such as 2 bits) of the SI field can be used as the SO field.

[0170] In some scenarios, the first information further comprises a fifth indication information. In some scenarios, the first information further comprises an SO. It should be noted that the length of the first length indication information can be predefined by a protocol or configured in advance to the terminal device by the network device through dedicated signaling. The length of the second length indication information can be predefined by a protocol or configured in advance to the terminal device by the network device through dedicated signaling.

[0171] In the following, the format of the physical layer TB is introduced by taking an example of transmitting the first information through the physical layer TB, as shown in FIG. 9A and FIG. 9B.

[0172] As shown in FIG. 9A, the TB can comprise a D / C field, a PHY layer control information type field, an SI field, an L field, an F field and a field for carrying the second information. The D / C field can occupy the first bit in Oct1, the PHY layer control information type field can occupy the second to fourth bits in Oct1, the F field occupies the fifth bit in Oct1, the SI field can occupy the sixth to seventh bits in Oct1, the L field occupies the remaining bits in Oct1 and all bits in Oct2, and the field for carrying the second information can occupy all bits in Oct3-OctN (N is a positive integer greater than or equal to 3).

[0173] Correspondingly, the D / C field is used to carry the fifth indication information, the F field is used to carry the second length indication information, the SI field is used to carry the segmentation indication information, the L field is used to carry the first length indication information, and the PHY layer control information type field is used to carry the first indication information.

[0174] In some scenarios, if the SI field indicates that the current physical layer TB is any one of the following: the current physical layer TB carries complete PHY configuration information, the current physical layer TB carries the first segment of the complete PHY configuration information, and the current physical layer TB carries the last segment of the complete PHY configuration information, the structure of the current physical layer TB can be referred to FIG. 9A, and correspondingly, the terminal device can decode according to the format shown in FIG. 9A.

[0175] Referring to FIG. 9B, the TB can include a D / C field, an F field, a PHY layer control information type field, an SI field, an SO field, an L field, and a field for carrying the second information. The D / C field can occupy the first bit in Oct1, the PHY layer control information type field can occupy the second to fourth bits in Oct1, the F field can occupy the fifth bit in Oct1, the SI field can occupy the sixth and seventh bits in Oct1, and the remaining bits in Oct1 are reserved (as an R field). The SO field occupies Oct2-Oct3, the L field occupies Oct4-Oct5, and the field for carrying the second information can occupy all bits in Oct6-OctN (N is a positive integer greater than or equal to 6).

[0176] Correspondingly, the D / C field is used to carry the fifth indication information, the SI field is used to carry the segment indication information, the SO field is used to carry the segment offset indication information, the F field is used to carry the second length indication information, the L field is used to carry the first length indication information, and the PHY layer control information type field is used to carry the first indication information.

[0177] In some scenarios, if the SI field indicates that the current physical layer TB carries a segment of complete PHY configuration information, the structure of the current physical layer TB can be as shown in FIG. 9B, and correspondingly, the terminal device can decode according to the format shown in FIG. 9B.

[0178] In some scenarios, the last several bits (for example, 2 bits, 3 bits, 4 bits, etc.) of the D / C field can be a reserved field (i.e., an R field). In other scenarios, the last several bits (for example, the last 2 bits) of the PHY layer control information type field can be a reserved field (i.e., an R field). In other scenarios, the last several bits (for example, the last 2 bits) of the SI field can be a reserved field (i.e., an R field). For example, referring again to FIG. 9B, the last bit of the SI field can be an R field. In the above cases, the first information can include the fifth indication information, the first indication information, the second length indication information, the SI, the reserved information, the first length indication information, and the second information. Optionally, the first information can also include the SO.

[0179] In addition, the position relationship between the SI field and the SO field in FIG. 9B is only exemplary, and embodiments of the present application do not limit the same. For example, the last several bits (for example, 1 bit) of the SI field can be used as the SO field.

[0180] The above describes the scheme that the first information includes the fifth indication information in the embodiments of the present application in combination with examples 1-5 to 1-10. In some scenarios, the first information can not include the fifth indication information, or in other words, the TB can not include the D / C field. For example, some communication devices (e.g., zero-power devices) can only have a physical layer, and in this case, the TB can not include the D / C field. In this scenario, the D / C field in examples 1-5 to 1-10 described above can be deleted. For ease of understanding, example 1-11 is taken as an example for description below.

[0181] Example 1-11: When the value of the first indication information is the first value, the first information at least includes the first indication information and the second information. The format of the physical layer TB in the embodiments of the present application is described below in combination with FIG. 10 by taking the transmission of the first information through the physical layer TB as an example.

[0182] Referring to FIG. 10, the TB can include a PHY layer control information type field and a field for carrying the second information. The PHY layer control information type field can occupy the first to third bits in Oct1, and the field for carrying the second information can occupy the remaining bits in Oct1 and all bits in Oct2-OctN (N is a positive integer greater than or equal to 2).

[0183] Correspondingly, the PHY layer control information type field is used to carry the first indication information, and the first indication information is used to indicate whether the PHY layer control information type is control information including the PHY configuration information. For example, if the value of the PHY layer control information type field is the first value, it indicates that the current processing PHY transport block includes the PHY configuration information, and conversely, if the value of the PHY layer control information type field is the fifth value, it indicates that the current processing PHY transport block does not include the PHY configuration information.

[0184] It should be noted that in some scenarios, the last several bits (e.g., 2 bits, 3 bits, 4 bits, etc.) of the PHY layer control information type field can be a reserved field (i.e., R field), and in this case, the first information can include the first indication information, the reserved information field, and the second information. Of course, the first information can also include one or more of the second length indication information, the segmentation indication information, the first length indication information, and the SO, and specific details can be referred to the description in examples 1-5 to 1-10, which will not be described here.

[0185] Embodiment 2: The first protocol layer is the MAC layer.

[0186] In the embodiments of the present application, the MAC layer of the network device can configure the MAC layer of the terminal device through the first information. In this way, after receiving the first information, the terminal device can directly submit the first information to the MAC layer (for example, from the physical layer to the MAC layer) for processing (for example, parsing) and configuration application. Compared with the traditional configuration process processing mode (regardless of the protocol layer to which the configuration information is configured, the configuration information of the protocol layer needs to be submitted layer by layer to the RRC layer for processing, and then the RRC layer transmits the processed configuration information back to the protocol layer configured to configure), the configuration method provided in the present application can help to reduce the time delay required for configuring the MAC layer parameters, so as to improve the efficiency of configuring the MAC layer. On the other hand, the configuration of the MAC layer in the terminal device is configured and managed by the MAC layer in the network device, which can significantly reduce the dependence of the configuration process on the RRC protocol layer, and is conducive to realizing a simple RRC protocol layer function.

[0187] In some implementations, the first information includes second indication information and / or third information, wherein the third information is used to carry the configuration information of the MAC layer, and the second indication information is a logical channel ID, and the value of the logical channel ID is used to determine whether the first information carries the configuration information of the MAC layer.

[0188] Taking the first information including the third information as an example, in the embodiments of the present application, the configuration information of the MAC layer is not limited. In some implementations, the configuration information of the MAC layer can include one or more of the following: a parameter related to a hybrid automatic repeat request (HARQ) function, a parameter related to a scheduling request (SR) function, a parameter related to a buffer status report (BSR) function, a parameter related to a beam failure recovery (BFR) function, a parameter related to a beam failure detection (BFD) function, a parameter related to a random access function, or a parameter related to a scheduling function.

[0189] In some implementations, the MAC layer configuration information is used to control the MAC layer function, which can be directly applied by the MAC layer after being parsed by the MAC layer, for example, the configuration parameters related to the HARQ function, without the need to be used in combination with the configuration provided additionally by the RRC protocol layer. In the conventional technology, the MAC layer cannot directly parse the MAC layer configuration information, and all the MAC layer configuration information is parsed by the RRC protocol layer and then delivered to the MAC layer through the interlayer interaction process. Although the MAC CE of the MAC layer can also be used to control the activation or deactivation of some configurations, the control information contained in the MAC CE is mostly the index index delivered by the RRC, and is not the configuration information itself, for example, the BWP ID, the TCI state ID, and the like. The MAC layer of the terminal device will determine which configurations delivered by the RRC need to be activated or deactivated according to the index contained in the MAC CE, which is essentially different from the configuration information of the embodiments of the present application.

[0190] In some implementations, the third information further includes message type indication information and / or group indication information, which helps the terminal device to confirm the format used to decode the MAC layer configuration information carried in the third information. In addition, the third information including the message type indication information and / or the group indication information can further increase the flexibility of the configuration, for example, a small number of parameters can be configured by the message type indication information and / or the group indication information, while most of the parameters are not reconfigured, thereby saving the overhead of the reconfiguration process.

[0191] In some implementations, the message type indication information is used to indicate the message type to which the MAC layer configuration information included in the third information belongs, or in other words, the message type indication information is used to indicate which kind of MAC layer message the MAC layer configuration information contained in the third information belongs to. In the embodiments of the present application, the implementation mode of the message type indication information is not limited. In some implementations, the message type indication information can be implemented or indicated by the choice function.

[0192] In some implementations, different values of the message type indication information can correspond to different message types. For example, the MAC layer configuration information can be divided into five message types, at this time, the message type indication information can occupy 3 bits, and each message type corresponds to a value, that is, message type 1 corresponds to the value '000', message type 2 corresponds to the value '001', message type 3 corresponds to the value '010', message type 4 corresponds to the value '011', and message type 5 corresponds to the value '100'.

[0193] The number of bits occupied by the message type indication information is not limited in the embodiments of the present application. For example, the message type indication information can occupy 3 bits. For another example, the message type indication information can occupy 2 bits. In addition, the content contained in different message types can be predefined in the embodiments of the present application.

[0194] In some implementations, the group indication information is used to indicate the parameter group to which the MAC layer configuration information included in the third information belongs, or in other words, the group indication information is used to indicate which group of parameters is intended to be configured in the current configuration process. The implementation of the group indication information is not limited in the embodiments of the present application. In some implementations, the group indication information can be implemented or indicated by a choice function.

[0195] In some implementations, different values of the group indication information can correspond to different parameter groups. For example, the MAC layer configuration information can be divided into 6 groups, at this time, the group indication information can occupy 3 bits, each group of configuration information corresponds to a value, that is, group 1 corresponds to value '000', group 2 corresponds to value '001', group 3 corresponds to value '010', group 4 corresponds to value '011', and group 5 corresponds to value '100'.

[0196] The number of bits occupied by the group indication information is not limited in the embodiments of the present application. For example, the group indication information can occupy 3 bits. For another example, the group indication information can occupy 2 bits. In addition, the content contained in different groups can be predefined in the embodiments of the present application.

[0197] The implementation of the third information is not limited in the embodiments of the present application. The following is introduced in combination with examples 2-1 to 2-4. It should be understood that the following mainly introduces the implementation of the third information, and the meaning of the information contained in the third information can be referred to the introduction in the foregoing.

[0198] Example 2-1: The third information includes the MAC layer configuration information.

[0199] Example 2-2: The third information includes the message type indication information and the MAC layer configuration information, wherein the message type indication information is used to indicate which message contained parameters are intended to be configured in the current configuration process.

[0200] For example, the MAC layer defines 2 message types: the first message type and the second message type, at this time, in order to let the terminal device know the MAC layer configuration information configured in the current configuration, the third information can carry the message type indication information, that is, the message type indication information is used to indicate that the MAC layer configuration information configured in the current configuration is the parameter in the first message type.

[0201] Example 2-3: The third information includes group indication information and MAC layer configuration information, wherein the group indication information is used to indicate which group of parameters configured in the current configuration process.

[0202] For example, the MAC layer defines 2 groups of parameters, at this time, in order to let the terminal device know the MAC layer configuration information configured in the current configuration, the third information can carry group indication information, that is, the group indication information can be used to indicate that the MAC layer configuration information configured in the current configuration is the first group of parameters.

[0203] Example 2-4: The third information includes message type indication information, group indication information and MAC layer configuration information, wherein the message type indication information is used to indicate which type of message a group of parameters configured in the current configuration process belongs to, and the group indication information is used to indicate which group of parameters in the message configured in the current configuration process.

[0204] For example, the MAC layer defines 2 types of messages, wherein the first type of message contains 2 groups of parameters, and the second type of message contains 3 groups of parameters, at this time, in order to let the terminal device know the MAC layer configuration information configured in the current configuration, the third information can carry message type indication information and group indication information, that is, through the message type indication information and the group indication information, it is indicated that the MAC layer configuration information configured in the current configuration is the first group of parameters in the first type of message.

[0205] The above introduces the third information in the embodiments of the present application, and the following introduces the second indication information in the embodiments of the present application.

[0206] Taking the first information including the second indication information as an example, in some implementation manners, the second indication information can be carried in the MAC subheader, or in other words, the logical channel ID is carried in the MAC subheader.

[0207] In some implementation manners, the logical channel ID can include LCID and / or eLCID.

[0208] In some implementation manners, when the first information includes the second indication information, and the value of the second indication information is the second value, the first information further includes the third information.

[0209] In some implementation manners, the value of the second indication information being the second value can be understood as the value of the logical channel ID being the second value.

[0210] In the embodiments of the present application, the specific value of the second value is not limited.

[0211] In some implementation manners, the value of the second value can be predefined, for example, the value of the second value can be predefined through a protocol.

[0212] In some other implementations, when the second indication information has a sixth value, the first information does not include the third information. That is, the second indication information indicates that the first information does not contain the configuration information of the MAC layer. For example, the first information contains a control instruction for activating or deactivating a configuration, and the configuration is obtained in advance by the terminal device (such as through the first information sent previously), and the control instruction contained in the first information can be implemented through an index or a bitmap of the configuration (one or several bits in the bitmap are associated with a configuration or a group of configurations), but the control instruction itself cannot be considered as a MAC layer configuration parameter, but should be considered as an action or instruction related to the MAC layer configuration parameter (such as the activation or deactivation action of the BWP, the activation or deactivation action of the SCell, and the like).

[0213] In the embodiments of the present application, the specific value of the sixth value is not limited, and the sixth value is different from the second value.

[0214] In some implementations, the value of the sixth value can be predefined, for example, the value of the sixth value can be predefined by a protocol.

[0215] In some implementations, the first information further includes third length indication information, where the third length indication information is used to indicate the length of the third information, which helps to simplify the complexity of receiving the third information. For example, the third length indication information is used to indicate the number of bytes occupied by the third information. For another example, the third length indication information is used to indicate the number of bits occupied by the third information.

[0216] In some implementations, the first length indication information can be carried in the L field. Details are described below in conjunction with FIG. 11.

[0217] In some implementations, the first information further includes fourth length indication information, where the fourth length indication information is used to indicate the length of the third length indication information, which helps to improve the flexibility of setting the length occupied by the third length indication information. For example, the fourth length indication information is used to indicate the number of bytes occupied by the third length indication information. For another example, the fourth length indication information is used to indicate the number of bits occupied by the third length indication information.

[0218] In the embodiments of the present application, the manner in which the fourth length indication information indicates the length of the third length indication information is not limited. In some implementations, the fourth length indication information can directly carry the actual length information of the third length indication information. In some other implementations, the value of the fourth length indication information can correspond to the actual length of the third length indication information one by one. For example, when the value of the fourth length indication information is '1', it can be agreed by a protocol that the third length indication information occupies 16 bits. For another example, when the value of the fourth length indication information is '0', it can be agreed by a protocol that the third length indication information occupies 8 bits.

[0219] In some implementations, the fourth length indication information can be carried in the F field. Details are described below in connection with FIG. 11.

[0220] In some implementations, the length of the third length indication information can be predefined, which helps to reduce the number of bits for transmitting the first information. For example, the length of the third length indication information can be agreed to occupy 8 bits in the protocol. For another example, the length of the third length indication information can be agreed to occupy 12 bits in the protocol. For another example, the length of the third length indication information can be agreed to occupy 15 bits in the protocol. For another example, the length of the third length indication information can be agreed to occupy 20 bits in the protocol.

[0221] In some implementations, the length of the third length indication information is configured by the network device, which helps to improve the flexibility of setting the length of the third length indication information. For example, the network device can configure the length of the third length indication information through dedicated signaling. For another example, the network device can configure the length of the third length indication information to occupy 8 bits through dedicated signaling. For another example, the network device can configure the length of the third length indication information to occupy 12 bits through dedicated signaling. For another example, the network device can configure the length of the third length indication information to occupy 18 bits through dedicated signaling. For another example, the network device can configure the length of the third length indication information to occupy 20 bits through dedicated signaling.

[0222] In some implementations, the first information can further include fifth indication information, where the fifth indication information is used to indicate whether the information carried by the first information is data type information or control type information.

[0223] In some implementations, if the fifth indication information indicates that the information carried by the first information is data type information, it means that the first information does not include the third information. It should be understood that in the embodiments of the present application, if the fifth indication information indicates that the information carried by the first information is data type information, the first information can carry application layer data type information or carry configuration information and / or non-configuration type control instructions of other protocol layers (for example, RLC layer, PDCP layer, etc.).

[0224] In some implementations, if the fifth indication information indicates that the information carried by the first information is data type information, the method further includes: the MAC layer of the terminal device submits the information in the third information that cannot be parsed by the MAC layer to the RLC layer of the terminal device for processing.

[0225] In some implementations, the fifth indication information can be carried in the R field in the MAC subheader.

[0226] In some embodiments, the first information does not include the fifth indication information, but the information carried by the first information is indicated as data type information or control type information by different values of the second indication information (values of LCID and / or eLCID).

[0227] In some embodiments, the first information does not include the fifth indication information, but the information carried by the first information is indicated as data type information or control type information by different values of the second indication information (values of LCID and / or eLCID).

[0228] For the convenience of understanding, the first information in the embodiments of the present application is introduced below in combination with Examples 2-5 to 2-11. It is assumed that Oct represents byte, and one byte occupies 8 bits. It should be understood that the following mainly introduces the implementation mode of the first information, and the meaning of the information contained in the first information can be referred to the introduction above.

[0229] In the embodiments of the present application, the scheme of carrying the first information by using different MAC headers helps to improve the flexibility of the scheme. For example, when the value of the traditional LCID is not enough, the value of eLCID can be considered to indicate that the current MAC PDU contains MAC layer configuration information. For another example, the value of the traditional LCID can be used to indicate that the current MAC PDU contains MAC layer configuration information, which helps to reduce the overhead of transmitting MAC subheader.

[0230] Example 2-5: When the value of the second indication information is the second value (i.e., the value of the LCID field is the second value), the first information at least includes the third length indication information, the fourth length indication information, the second indication information and the third information. The format of the MAC subheader in the embodiments of the present application is introduced below in combination with FIG. 11, wherein the third length indication information, the fourth length indication information and the second indication information included in the first information are carried by the MAC subheader of FIG. 11, and the length of the third information included in the first information is indicated by the third length indication information. It should be understood that the third information included in the first information is carried by the information field (such as the information field after the L field) outside the MAC subheader.

[0231] Referring to FIG. 11, the MAC subheader can include an R field, an F field, an L field, and an LCID field. The R field can occupy the first bit of Oct1, the F field can occupy the second bit of Oct1, the LCID field can occupy the remaining bits of Oct1, and the L field can occupy Oct2. Accordingly, the R field is a reserved field, the F field is used to carry fourth length indication information, the L field is used to carry third length indication information (e.g., the L field is used to indicate the length of a MAC SDU or a variable MAC CE), and the LCID field is used to carry second indication information.

[0232] In the MAC subheader shown in FIG. 11, the value of the second value is also the value of the index associated with the second value, and each value of the index is associated with a function or a characteristic. The association between the value of the index and the function (or the characteristic) is defined by a protocol in a predefined manner. For example, when the index is 0, the corresponding function includes a configuration for the MAC layer, that is, the first information carries configuration information of the MAC layer.

[0233] In addition, the value range of the second value corresponds to the value range of the index associated with the second value. For example, the value range of the second value is 0-63, and accordingly, the value range of the index associated with the second value is 0-63. When the value of the second value is 0, the value of the index associated with the second value is 0. When the value of the second value is 1, the value of the index associated with the second value is 1, and so on.

[0234] Example 2-6: When the value of the second indication information is the second value (i.e., the value of the LCID field is the second value), the first information at least includes third length indication information, fourth length indication information, the second indication information, and third information. Hereinafter, the format of the MAC subheader in the embodiment of the application is introduced by taking FIG. 12 as an example. The third length indication information, the fourth length indication information, and the second indication information included in the first information are carried by the MAC subheader of FIG. 12, and the length of the third information included in the first information is indicated by the third length indication information. It should be understood that the third information included in the first information is carried by an information field (such as an information field after the L field) other than the MAC subheader.

[0235] Referring to FIG. 12, the MAC subheader can include an R field, an F field, an L field, and an LCID field. The R field can occupy the first bit of Oct1, the F field can occupy the second bit of Oct1, the LCID field can occupy the remaining bits of Oct1, and the L field can occupy Oct2-Oct3. Accordingly, the R field is a reserved field, the F field is used to carry fourth length indication information, the L field is used to carry third length indication information (e.g., the L field is used to indicate the length of a MAC SDU or a variable MAC CE), and the LCID field is used to carry second indication information.

[0236] In the MAC subheader shown in FIG. 12, the value of the second value is also the value of the index associated with the second value, the value of each index is associated with a function or a feature, and the association between the value of the index and the function (or feature) is defined by the protocol in a predefined manner. For example, when the index is 0, the corresponding function includes the configuration for the MAC layer, that is, the first information carries the configuration information of the MAC layer.

[0237] In addition, the value range of the second value corresponds to the value range of the index associated with the second value. For example, the value range of the second value is 0-63, and correspondingly, the value range of the index associated with the second value is 0-63. When the value of the second value is 0, the value of the index associated with the second value is 0. When the value of the second value is 1, the value of the index associated with the second value is 1, and so on.

[0238] Example 2-7: When the value of the second indication information is the second value, the first information at least includes third length indication information, fourth length indication information, the second indication information, and third information. In the following, taking FIG. 13 as an example, the format of the MAC subheader in the embodiment of the application is introduced, wherein the third length indication information, the fourth length indication information, and the second indication information included in the first information are carried by the MAC subheader of FIG. 13, and the length of the third information included in the first information is indicated by the third length indication information. It should be understood that the third information included in the first information is carried by the information field (such as the information field after the L field) outside the MAC subheader.

[0239] Referring to FIG. 13, the MAC subheader can include an R field, an F field, an L field, an eLCID field, and an LCID field. Among them, the R field can occupy the first bit in Oct1, the F field can occupy the second bit in Oct1, the LCID field can occupy the remaining bits in Oct1, the eLCID field can occupy Oct2, and the L field can occupy Oct3. Correspondingly, the R field is a reserved field, the F field is used to carry the fourth length indication information, the L field is used to carry the third length indication information (for example, the L field is used to indicate the length of the MAC SDU or the variable MAC CE), the LCID field and the eLCID field are used to carry the second indication information, and one of the values of the LCID field is used to indicate the existence of the eLCID field.

[0240] In the MAC subheader shown in FIG. 13, the difference between the value of the index associated with the second value and the second value (the value of the second indication information) is a fixed value. The value of each index is associated with a function or a feature, and the association between the value of the index and the function (or feature) is defined by the protocol in a predefined manner. For example, when the index is 64, the corresponding function includes the configuration for the MAC layer, that is, the first information carries the configuration information of the MAC layer.

[0241] In addition, the value range of the second value corresponds to the value range of the index associated with the second value. For example, the value range of the second value is 0-255, and correspondingly, the value range of the index associated with the second value is 64-319, where the value of the second value of 0 corresponds to the value of the index associated with the second value of 64, the value of the second value of 1 corresponds to the value of the index associated with the second value of 65, and so on.

[0242] In Example 2-8, when the value of the second indication information is the second value, the first information at least includes third length indication information, fourth length indication information, the second indication information, and third information. The format of the MAC subheader in the embodiment of the present application is described below with reference to FIG. 14, where the third length indication information, the fourth length indication information, and the second indication information included in the first information are carried by the MAC subheader of FIG. 14, and the length of the third information included in the first information is indicated by the third length indication information. It should be understood that the third information included in the first information is carried by an information field (such as an information field after the L field) other than the MAC subheader.

[0243] Referring to FIG. 14, the MAC subheader can include an R field, an F field, an L field, an eLCID field, and an LCID field. The R field can occupy the first bit in Oct1, the F field can occupy the second bit in Oct1, the LCID field can occupy the remaining bits in Oct1, the eLCID field can occupy Oct2, and the L field can occupy Oct3-Oct4. Correspondingly, the R field is a reserved field, the F field is used to carry the fourth length indication information, the L field is used to carry the third length indication information (for example, the L field is used to indicate the length of the MAC SDU or the variable MAC CE), the LCID field and the eLCID field are used to carry the second indication information, where a certain agreed value of the LCID field is used to indicate the presence of the eLCID field.

[0244] In the MAC subheader shown in FIG. 14, the difference between the value of the index associated with the second value and the second value (the value of the second indication information) is a constant value. Each value of the index is associated with a function or a characteristic, and the association between the value of the index and the function (or the characteristic) is agreed by the protocol in a predefined manner. For example, when the index is 64, the corresponding function includes the configuration for the MAC layer, that is, the first information carries the configuration information of the MAC layer.

[0245] In addition, the value range of the second value corresponds to the value range of the index associated with the second value. For example, the value range of the second value is 0-255, and correspondingly, the value range of the index associated with the second value is 64-319, where the value of the second value of 0 corresponds to the value of the index associated with the second value of 64, the value of the second value of 1 corresponds to the value of the index associated with the second value of 65, and so on.

[0246] Example 2-9: When the value of the second indication information is the second value, the first information includes at least the third length indication information, the fourth length indication information, the second indication information, and the third information. The following description, using Figure 15 as an example, illustrates the format of the MAC subheader in this embodiment. The third length indication information, the fourth length indication information, and the second indication information included in the first information are carried by the MAC subheader in Figure 15. The length of the third information included in the first information is indicated by the third length indication information. It should be understood that the third information included in the first information is carried by an information field outside the MAC subheader (e.g., the information field after the L field).

[0247] Referring to Figure 15, the MAC subheader may include an R field, an F field, an L field, an eLCID field, and an LCID field. The R field may occupy the first bit of Oct1, the F field may occupy the second bit of Oct1, the LCID field may occupy the remaining bits of Oct1, the eLCID field may occupy Oct2-Oct3, and the L field may occupy Oct4. Accordingly, the R field is a reserved field, the F field is used to carry fourth length indication information, the L field is used to carry third length indication information (e.g., the L field indicates the length of the MAC SDU or variable MAC CE), and the LCID and eLCID fields are used to carry second indication information. A conventional value for the LCID field is used to indicate the presence of the eLCID field.

[0248] In the MAC header shown in Figure 15, the difference between the index associated with the second value and the second value (the value of the second indication information) is a constant. Each index value is associated with a function or feature, and the association between the index value and the function (or feature) is agreed upon through a predefined protocol. For example, when the index is 320, the corresponding function includes configuration for the MAC layer; that is, the first information carries the configuration information for the MAC layer.

[0249] Furthermore, the range of the second value corresponds one-to-one with the range of the subscript associated with the second value. For example, the range of the second value is 0 to (2... 16 —1), while the range of values ​​for the subscript associated with the second value is 320 to (2). 16 If the second value is 0, then the value of the second value is 320, the value of the second value is 1, the value of the second value is 321, and so on.

[0250] Example 2-10: When the value of the second indication information is the second value, the first information includes at least the third length indication information, the fourth length indication information, the second indication information, and the third information. The following description, using Figure 16 as an example, illustrates the format of the MAC subheader in this embodiment. The third length indication information, the fourth length indication information, and the second indication information included in the first information are carried by the MAC subheader of Figure 16. The length of the third information included in the first information is indicated by the third length indication information. It should be understood that the third information included in the first information is carried by an information field outside the MAC subheader (e.g., the information field after the L field).

[0251] Referring to Figure 16, the MAC subheader may include an R field, an F field, an L field, an eLCID field, and an LCID field. The R field may occupy the first bit of Oct1, the F field may occupy the second bit of Oct1, the LCID field may occupy the remaining bits of Oct1, the eLCID field may occupy Oct2-Oct3, and the L field may occupy Oct4-Oct5. Accordingly, the R field is a reserved field, the F field is used to carry fourth length indication information, the L field is used to carry third length indication information (e.g., the L field indicates the length of the MAC SDU or variable MAC CE), and the LCID and eLCID fields are used to carry second indication information. A conventional value for the LCID field is used to indicate the presence of the eLCID field.

[0252] In the MAC header shown in Figure 16, the difference between the index associated with the second value and the second value (the value of the second indication information) is a constant. Each index value is associated with a function or feature, and the association between the index value and the function (or feature) is agreed upon through a predefined protocol. For example, when the index is 320, the corresponding function includes configuration for the MAC layer; that is, the first information carries the configuration information for the MAC layer.

[0253] Furthermore, the range of the second value corresponds one-to-one with the range of the subscript associated with the second value. For example, the range of the second value is 0 to (2... 16 —1), while the range of values ​​for the subscript associated with the second value is 320 to (2). 16 If the second value is 0, then the value of the second value is 320, the value of the second value is 1, the value of the second value is 321, and so on.

[0254] It should be noted that the above introduces the schematic diagram of the MAC subheader of the embodiments of the present application in combination with Examples 2-5 to 2-10. In some other embodiments of the present application, the MAC subheader introduced in Examples 2-5 to 2-10 can not contain the F field or not contain the F field and the L field. In addition, in some other embodiments of the present application, the MAC subheader introduced in Examples 2-5 to 2-10 can not contain the R field. At this time, the MAC subheader can include the R field and the LCID field; or include the R field, the LCID field and the eLCID field; or include the R field, the LCID field and the L field; or include the R field, the LCID field, the eLCID field and the L field; or include the LCID field; or include the LCID field and the eLCID field; or include the LCID field and the L field; or include the LCID field, the eLCID field and the L field.

[0255] Optionally, when the value of the second indication information is a ninth value (for example, the value of the LCID field or the value of the eLCID field is the ninth value), the second indication information is used to indicate that the first information (i.e., the first information of the MAC layer) contains the physical layer configuration information, at this time, the first information at least includes the second indication information and the sixth information, wherein the sixth information carries the physical layer configuration information. The MAC subheader corresponding to the MAC PDU carrying the first information is any one of the MAC subheaders introduced in the examples 2-5 to 2-10. At this time, the behavior of the MAC layer of the terminal device further includes delivering the extracted sixth information containing the physical layer configuration information to the physical layer processing of the terminal device, at this time, the sixth information to the physical layer is treated by the physical layer as the first information of the physical layer, and the manner in which the physical layer processes the first information is as described in the examples 1-5 to 1-11 above, which is not repeated here. In this implementation manner, the physical layer configuration information sent by the network device needs to first reach the MAC layer of the terminal device for processing, and the reason can be that the MAC layer needs to perform data decryption processing (and / or integrity protection processing), and only after the data decryption (and / or integrity protection processing), the meaning of the information contained in the MAC PDU can be parsed. After the MAC layer decrypts (and / or integrity protection processing) the MAC PDU data, if it is confirmed that the value of the second indication information is the ninth value, it can be confirmed that the MAC PDU data currently decrypted (and / or integrity protection processing) contains the physical layer configuration information (i.e., the sixth information), so that the sixth information is extracted and sent to the physical layer processing of the terminal device. Similarly, in the above scenario, the configuration generated by the physical layer of the network device cannot be directly sent to the physical layer of the terminal device over the air, because the configuration data has not been encrypted (and / or integrity protection processing), and the physical layer of the network device needs to first send the generated physical layer configuration information to the MAC layer of the network device for encryption processing (and / or integrity protection processing), and then the MAC layer of the network device returns the encrypted (and / or integrity protection processing) data to the physical layer of the network device for sending, and the present application does not exclude this manner of configuring the physical layer configuration.

[0256] Embodiment 3: The first protocol layer is the RLC layer.

[0257] In the embodiments of the present application, the RLC layer of the network device can configure the RLC layer of the terminal device through the first information. In this way, after receiving the first information, the terminal device can directly submit the first information to the RLC layer (for example, from the physical layer to the MAC layer, and then from the MAC layer to the RLC layer) for processing (for example, parsing) and configuration application. Compared with the traditional configuration process processing mode (regardless of which protocol layer the configuration information of the protocol layer is configured, the configuration information of the protocol layer needs to be submitted to the RRC layer layer by layer for processing, and then the RRC layer transmits the processed configuration information back to the configured protocol layer for configuration), the configuration method provided in the present application helps to reduce the time delay required for configuring the RLC layer, so as to improve the efficiency of configuring the RLC layer. On the other hand, the configuration of the RLC layer in the terminal device is configured and managed by the RLC layer in the network device, which can significantly reduce the dependence of the configuration process on the RRC protocol layer, and is conducive to realizing a simple RRC protocol layer function.

[0258] In some implementations, the first information includes third indication information and / or fourth information, wherein the third indication information is used to indicate the RLC control PDU type, and the fourth information is used to carry the configuration information of the RLC layer.

[0259] Taking the first information including the fourth information as an example, the control PDU of the RLC layer can include the configuration information of the RLC layer.

[0260] In the embodiments of the present application, the configuration information of the RLC layer is not limited. In some implementations, the configuration information of the RLC layer can include one or more of the following: automatic repeat reQuest (ARQ) function related parameters, segmentation related parameters, and RLC layer mode related indication information, wherein the RLC layer mode includes one or more of the following: transport mode (TM), unacknowledged mode (UM), and acknowledged mode (AM).

[0261] In some implementations, the RLC configuration information is used to control the RLC function, and after being parsed by the RLC, the RLC configuration information can be directly applied by the RLC, for example: ARQ function related configuration parameters, without the need for additional configuration provided by the RRC protocol layer. In the traditional technology, the RLC cannot directly parse the RLC configuration information, and all RLC configuration information is parsed by the RRC protocol layer and then transmitted to the RLC through the interlayer interaction process. Although the RLC protocol layer also has some control PDUs, for example: status report PDU, there is no control PDU directly containing the RLC layer configuration, which is essentially different from the configuration information in the embodiments of the present application.

[0262] In some embodiments, the fourth information further comprises message type indication information and / or group indication information, which helps the terminal device to confirm how to decode the RLC layer configuration information carried in the fourth information. In addition, the fourth information comprising the message type indication information and / or the group indication information can further increase the flexibility of the configuration, for example, a small number of parameters can be indicated by the message type indication information and / or the group indication information to be configured incrementally while most of the parameters are not reconfigured, thereby saving the overhead of the reconfiguration process.

[0263] In some embodiments, the message type indication information is used to indicate the message type to which the RLC layer configuration information included in the fourth information belongs, or in other words, the message type indication information is used to indicate which kind of RLC layer message the RLC layer configuration information included in the fourth information belongs to. In the embodiments of the present application, the implementation of the message type indication information is not limited. In some embodiments, the message type indication information can be implemented by a choice function or identification information indication.

[0264] In some embodiments, different values of the message type indication information can correspond to different message types. For example, the RLC layer configuration information can be divided into 5 message types, at this time, the message type indication information can occupy 3 bits, each message type corresponds to a value, that is, message type 1 corresponds to value '000', message type 2 corresponds to value '001', message type 3 corresponds to value '010', message type 4 corresponds to value '011', and message type 5 corresponds to value '100'.

[0265] In the embodiments of the present application, the number of bits occupied by the message type indication information is not limited. For example, the message type indication information can occupy 3 bits. For another example, the message type indication information can occupy 2 bits. In addition, in the embodiments of the present application, the content contained in different message types can be predefined.

[0266] In some embodiments, the group indication information is used to indicate the parameter group to which the RLC layer configuration information included in the fourth information belongs, or in other words, the group indication information is used to indicate which group of parameters is intended to be configured in this round of configuration process. In the embodiments of the present application, the implementation of the group indication information is not limited. In some embodiments, the group indication information can be implemented by a choice function or identification information indication.

[0267] In some implementations, different values of the group indication information can correspond to different groups. For example, the RLC layer configuration information can be divided into 5 groups, and in this case, the group indication information can occupy 3 bits, and each group of configuration information corresponds to a value, i.e., group 1 corresponds to value '000', group 2 corresponds to value '001', group 3 corresponds to value '010', group 4 corresponds to value '011', and group 5 corresponds to value '100'.

[0268] In the embodiments of the present application, the number of bits occupied by the group indication information is not limited. For example, the group indication information can occupy 3 bits. For another example, the group indication information can occupy 2 bits. In addition, in the embodiments of the present application, the content contained in different groups can be predefined.

[0269] In the embodiments of the present application, the implementation mode of the fourth information is not limited. The following describes examples 3-1 to 3-4. It should be understood that the following mainly describes the implementation mode of the fourth information, and the meaning of the information contained in the fourth information can be referred to the description above.

[0270] Example 3-1: The fourth information includes RLC layer configuration information.

[0271] Example 3-2: The fourth information includes message type indication information and RLC layer configuration information, wherein the message type indication information is used to indicate which type of message the current configuration process intends to configure.

[0272] For example, the RLC layer defines two message types: a first message type and a second message type, and in this case, in order to let the terminal device know the RLC layer configuration information of the current configuration, the fourth information can carry the message type indication information, i.e., the message type indication information indicates that the RLC layer configuration information of the current configuration is the parameter in the first message type.

[0273] Example 3-3: The fourth information includes group indication information and RLC layer configuration information, wherein the group indication information is used to indicate which group of parameters the current configuration process configures.

[0274] For example, the RLC layer defines two groups of parameters, and in this case, in order to let the terminal device know the RLC layer configuration information of the current configuration, the fourth information can carry the group indication information, i.e., the group indication information can be used to indicate that the RLC layer configuration information of the current configuration is the first group of parameters.

[0275] Example 3-4: The fourth information includes message type indication information, group indication information and RLC layer configuration information, wherein the message type indication information is used to indicate which type of message the group of parameters the current configuration process intends to configure belongs to, and the group indication information is used to indicate which group of parameters in the message the current configuration process intends to configure.

[0276] For example, the RLC layer defines two message types, the first message type contains two groups of parameters, and the second message type contains three groups of parameters. At this time, in order to make the terminal device clear the RLC layer configuration information configured in this round, the fourth information can carry message type indication information and group indication information, that is, the message type indication information and the group indication information indicate that the RLC layer configuration information configured in this round is the first group of parameters in the first message type.

[0277] The fourth information in the embodiments of the present application is introduced above, and the third indication information in the embodiments of the present application is introduced below.

[0278] For example, when the third indication information takes the third value, the first information further includes the fourth information, and the RLC control PDU type indicated by the third indication information is a control PDU containing the configuration information of the RLC layer.

[0279] That is, the third indication information is used to indicate the RLC control PDU type (CPT), and accordingly, the third indication information can be carried in the CPT field. For example, the CPT field takes the value of '000' to indicate that the current decoded RLC control PDU is a status PDU (STATUS PDU), and the CPT field takes the value of '001' to indicate that the current decoded RLC PDU is an RLC configuration PDU.

[0280] In the embodiments of the present application, the value of the third value is not limited. For example, when the third indication information takes the value of '001', the RLC control PDU type indicated by the third indication information is a control PDU containing the configuration information of the RLC layer. Of course, in the embodiments of the present application, the value of the third value can also be '011' or '010'.

[0281] In some implementations, the value of the third value can be predefined, for example, the value of the third value can be predefined by a protocol.

[0282] In some implementations, when the third indication information takes the seventh value, the first information does not include the fourth information. In this case, the RLC control PDU type indicated by the third indication information is a control PDU that does not contain RLC layer configuration information. For example, the first information contains control instructions for activating or deactivating a configuration, and these configurations are obtained in advance by the terminal device (e.g., configured through previously sent first information). In this case, the control instructions contained in the first information can be implemented through the configuration index or bit map (one or more bits in the bit map are associated with a configuration or a group of configurations). However, the control instructions themselves cannot be considered as RLC layer configuration parameters, but should be considered as actions or instructions related to RLC layer configuration parameters (e.g., RLC mode activation / deactivation actions, triggering status report reporting actions, etc.).

[0283] In this embodiment, the specific value of the seventh value is not limited, and the seventh value is different from the third value. Taking the seventh value as '000' as an example, when the value of the third indication information is '000', the RLC control PDU type indicated by the third indication information is a control PDU that does not contain configuration information of the RLC layer. Of course, in this embodiment, the value of the seventh value can also be "111".

[0284] In some implementations, the value of the seventh value can be predefined; for example, the value of the seventh value can be predefined through a protocol.

[0285] In some implementations, there is a one-to-one correspondence between the value of the third indication information and the type of the RLC control PDU.

[0286] In some implementations, the first information may further include segmentation indication information and / or fifth length indication information. For example, the first information may also include segmentation indication information and fifth length indication information. Alternatively, the first information may also include segmentation indication information. Another example is that the first information may also include fifth length indication information.

[0287] Taking the inclusion of a fifth length indication information as an example, in some implementations, the fifth length indication information is used to indicate the length of the fourth information, which helps to provide at least two types of RLC layer control information with different lengths through the first information. For example, through the flexible indication of the fifth length indication information, it can be determined that the first information may contain only the fourth information, or the first information may contain both the fourth information and other RLC layer control information. Compared to methods without a fifth length indication information, the indication of the first information including the fifth length indication information in the embodiments of this application is more flexible.

[0288] For example, the fifth length indicator is used to indicate the number of bytes occupied by the fourth information. Or, for another example, the fifth length indicator is used to indicate the number of bits occupied by the fourth information.

[0289] In some implementations, the fifth length indication information can be carried in the L field. Details are described below with reference to FIG. 18.

[0290] In some scenarios, the fourth information is carried in the RLC PDU, and if the fourth information in the RLC PDU is followed by other RLC control information, whether the RLC PDU contains other RLC control information can be implicitly indicated by the L field. If the L field indicates that the fourth information occupies all the remaining information field of the RLC PDU, the RLC PDU does not contain other RLC control information. Otherwise, if the L field indicates that the fourth information does not occupy all the remaining information field of the RLC PDU, the RLC PDU contains other RLC control information.

[0291] In some implementations, the first information further includes sixth length indication information, and the sixth length indication information is used to indicate the length of the fifth length indication information, which helps to improve the flexibility of setting the length of the fifth length indication information. For example, the sixth length indication information is used to indicate the number of bytes occupied by the fifth length indication information. For another example, the sixth length indication information is used to indicate the number of bits occupied by the fifth length indication information.

[0292] In the embodiments of the present application, the manner in which the sixth length indication information indicates the length of the fifth length indication information is not limited. In some implementations, the sixth length indication information can directly carry the actual length information of the fifth length indication information. In other implementations, the value of the sixth length indication information can correspond to the actual length of the fifth length indication information one by one. For example, when the value of the sixth length indication information is '1', the fifth length indication information can be agreed to occupy 19 bits through a protocol. For another example, when the value of the sixth length indication information is '0', the fifth length indication information can be agreed to occupy 11 bits through a protocol.

[0293] In some implementations, the sixth length indication information can be carried in the F field. For example, refer to FIG. 19.

[0294] In other implementations, the length of the fifth length indication information can be predefined, which helps to reduce the number of bits for transmitting the first information. For example, the length of the fifth length indication information can be agreed to occupy 7 bits in the protocol. For another example, the length of the fifth length indication information can be agreed to occupy 12 bits in the protocol. For another example, the length of the fifth length indication information can be agreed to occupy 15 bits in the protocol. For another example, the length of the fifth length indication information can be agreed to occupy 20 bits in the protocol.

[0295] In some implementations, the length of the fifth length indication information is configured by the network device, which helps improve the flexibility of the length setting of the first length indication information. For example, the network device can configure the length of the fifth length indication information through dedicated signaling. For another example, the network device can configure the length of the fifth length indication information to occupy 4 bits through dedicated signaling. For another example, the network device can configure the length of the fifth length indication information to occupy 12 bits through dedicated signaling. For another example, the network device can configure the length of the fifth length indication information to occupy 18 bits through dedicated signaling. For another example, the network device can configure the length of the fifth length indication information to occupy 20 bits through dedicated signaling.

[0296] Taking the first information including the segment indication information as an example, in some implementations, the segment indication information is used to indicate the second state corresponding to the information contained in the fourth information, which helps improve the flexibility of the configuration process. Generally, considering that the information capacity of a single first information is limited, if a single first information cannot carry all the configuration information provided in the current reconfiguration process, the segment indication information can be introduced into the first information to realize the segmented reception and recombination of the configuration information.

[0297] In some implementations, the segment indication information can be carried in the SI field. This will be described below in conjunction with FIGS. 20A and 20B.

[0298] In some implementations, the second state described above is used to indicate one or more of the following: the fourth information carries complete configuration information; the fourth information carries the first segment of the complete configuration information; the fourth information carries the last segment of the complete configuration information; the fourth information carries an intermediate segment of the complete configuration information, where the intermediate segment can be understood as a segment other than the first segment and the last segment among the multiple segments corresponding to the complete configuration information.

[0299] It should be emphasized that the complete configuration information here is a relative concept. For example, if the network device's RLC layer prepares 1000 bits of parameters for the RLC layer of the terminal device in this configuration process, the 1000 bits transmitted in this configuration process can be considered as complete configuration information. If the network device's RLC layer prepares 1200 bits of parameters for the RLC layer of the terminal device in the next configuration process, the 1200 bits transmitted in the next configuration process can be considered as complete configuration information. If a single first information cannot transmit the complete configuration information, the complete configuration information needs to be segmented and transmitted, and each configuration segment is carried by a single first information. According to the segmentation, the complete configuration information can be transmitted by one or more first information.

[0300] For example, the fourth information can be transmitted in the manner of RLC PDU, and the second state is used to indicate one of the following: the fourth information carries complete RLC layer configuration information, the fourth information carries a first segment of the complete RLC layer configuration information, the fourth information carries a last segment of the complete RLC layer configuration information, and the fourth information carries an intermediate segment of the complete RLC layer configuration information.

[0301] In some implementations, if the second state indicated by the segment indication information is that the fourth information carries an intermediate segment of the complete configuration information, the first information further includes segment offset indication information SO.

[0302] In some implementations, the SO is used to indicate a first byte in the configuration information carried by the fourth information in a byte number (which can be a logical number or an actual number) in the complete RLC layer configuration information. For example, the SO is used to indicate a second offset, which is an offset value between a logical number corresponding to a first byte in the configuration information carried by the fourth information and a logical number corresponding to a first byte in the complete RLC layer configuration information, or in other words, the second offset is a byte number difference between the logical number corresponding to the first byte (or first byte data) in the configuration information carried by the fourth information and the logical number corresponding to the first byte (or first byte data) in the complete RLC layer configuration information.

[0303] It should be understood that in the embodiments of the present application, the logical number can correspond to a plurality of actual byte numbers in the complete RLC layer configuration information, which helps to reduce the number of bits of information carried in the SO field. For example, the actual byte numbers of the complete RLC layer configuration information include 1000 bytes, the logical number 0 can correspond to the actual byte numbers including 0-299, the logical number 1 can correspond to the actual byte numbers including 300-699, and the logical number 2 can correspond to the actual byte numbers including 700-999. When the second RLC PDU is transmitted, the value of the SO field in the first information is 1.

[0304] Of course, in the embodiments of the present application, the logical number can also correspond to the actual byte number of the complete RLC layer configuration information one by one, which is helpful to simplify the mapping relationship between the logical change and the actual byte number. For example, a complete RLC layer configuration information contains 1000 actual bytes (the actual byte numbers of the complete RLC layer configuration information are 0-999 in turn, and the actual byte number starts from 0), which is divided into 3 RLC PDUs for transmission, the first RLC PDU occupies 300 actual bytes (the actual byte numbers of the information contained in the first RLC PDU are 0-299 in turn), the second RLC PDU occupies 400 actual bytes (the actual byte numbers of the information contained in the second RLC PDU are 300-699 in turn), and the third RLC PDU occupies 300 actual bytes (the actual byte numbers of the information contained in the third RLC PDU are 700-999 in turn), when the second RLC PDU is transmitted, the value of the SO field in the first information is 300.

[0305] It should be noted that the actual byte number here can also be regarded as a logical number, which is used to indicate the logical order relationship of the occurrence of data, so as to facilitate the recombination of the segmented data by the data receiving party, and does not represent the actual address number of the computer storing the data. In some implementation modes, the segmentation indication information can be carried in the SI field. The following is introduced in combination with FIG. 20A and FIG. 20B.

[0306] In the embodiments of the present application, the representation of the four meanings of the second state is not limited. In some implementation modes, '00', '01', '10' and '11' can be used in turn to represent the four meanings of the second state.

[0307] In some implementation modes, the first information can further include fifth indication information, wherein the fifth indication information is used to indicate whether the information carried by the first information is data type information or control type information. For example, the fifth indication information is used to indicate whether the corresponding PDU is a control PDU or a data PDU, that is, the value of the fifth indication information is '0', which indicates that the current decoded RLC PDU is a control PDU, and the value of the D / C field is '1', which indicates that the current decoded RLC PDU is a data PDU.

[0308] In some implementation modes, the fifth indication information can be carried in the D / C field, which is introduced in combination with FIG. 17.

[0309] In some embodiments, if the fifth indication information indicates that the information carried by the first information is data type information, it means that the first information does not include the fourth information, or in other words, the first information does not need to be parsed by the RLC layer. It should be understood that in the embodiments of the present application, if the fifth indication information indicates that the information carried by the first information is data type information, the first information can carry application layer data type information or can carry configuration information and / or non-configuration type control information of other protocol layers (for example, PDCP layer, etc.).

[0310] In some embodiments, if the fifth indication information indicates that the information carried by the first information is data type information, the method further includes: the RLC layer of the terminal device delivers the information in the first information that cannot be parsed by the RLC layer to the PDCP layer of the terminal device for processing.

[0311] In some other embodiments, if the fifth indication information indicates that the information carried by the first information is control type information, the first information can include the fourth information. At this time, it can be further judged based on the third indication information whether the RLC control PDU type is control information containing configuration information of the RLC layer. That is to say, in this way, the first information can include the fifth indication information and the third indication information. Of course, in the embodiments of the present application, if the fifth indication information indicates that the information carried by the first information is control type information, the first information includes the fourth information. At this time, it can be considered that the RLC control PDU type only exists in the control information containing the configuration information of the RLC layer. That is to say, in this way, the first information can include the fifth indication information and does not contain the third indication information.

[0312] In order to facilitate understanding, the first information in the embodiments of the present application is introduced below in combination with Examples 3-5 to 3-10. It is assumed that Oct represents a byte, and one byte occupies 8 bits. It should be understood that the following mainly introduces the implementation mode of the first information, and the meaning of the information contained in the first information can be referred to the introduction above.

[0313] Example 3-5: When the value of the third indication information is the third value, the first information at least includes the third indication information and the fourth information, and optionally includes the fifth indication information. The format of the RLC PDU in the embodiments of the present application is introduced below in combination with FIG. 17 by taking the transmission of the first information through the RLC PDU as an example.

[0314] Referring to FIG. 17, the RLC PDU can include a D / C field, a CPT field, and a field for carrying the fourth information. Among them, the D / C field can occupy the first bit in Oct1, the CPT field can occupy the second to fourth bits in Oct1, and the field for carrying the fourth information can occupy the remaining bits in Oct1 and all bits in Oct2-OctN (N is a positive integer greater than or equal to 2).

[0315] Accordingly, the D / C field is used to carry the fifth indication information, and the CPT field is used to carry the third indication information, which is used to indicate whether the RLC layer control PDU type is control information containing RLC layer configuration information. For example, if the CPT field takes the third value, it indicates that the currently processed RLC PDU contains RLC configuration information, and conversely, if the CPT field takes the seventh value, it indicates that the currently processed RLC PDU does not contain RLC configuration information.

[0316] It should be noted that in some scenarios, the last several bits (for example, 2 bits, 3 bits, 4 bits, etc.) of the D / C field can be a reserved field (i.e., R field), and in other scenarios, the last several bits (for example, 2 bits, 3 bits, 4 bits, etc.) of the CPT field can be a reserved field. At this time, the first information can include the third indication information, the reserved information field, the fifth indication information, and the fourth information.

[0317] Example 3-6: When the third indication information takes the third value, the first information at least includes the third indication information, the fifth length indication information, and the fourth information, and optionally includes the fifth indication information. It should be noted that the length of the above-mentioned fifth length indication information can be protocol predefined or configured in advance to the terminal device by the network device through dedicated signaling.

[0318] In the following, the format of the RLC PDU in the embodiments of the present application is introduced by taking the transmission of the first information through the RLC PDU as an example in combination with FIG. 18. Referring to FIG. 18, the RLC PDU can include the D / C field, the CPT field, the L field, and the field used to carry the fourth information. Among them, the D / C field can occupy the first bit in Oct1, the CPT field can occupy the second to fourth bits in Oct1, the L field can occupy the remaining bits in Oct1 and all bits in Oct2, and the field used to carry the fourth information can occupy all bits in Oct3-OctN (N is a positive integer greater than or equal to 3).

[0319] Accordingly, the D / C field is used to carry the fifth indication information, and the L field is used to carry the fifth length indication information, and the CPT field is used to carry the third indication information, which is used to indicate whether the RLC layer control PDU type is control information containing RLC layer configuration information. For example, if the CPT field takes the third value, it indicates that the currently processed RLC PDU contains RLC configuration information, and conversely, if the CPT field takes the seventh value, it indicates that the currently processed RLC PDU does not contain RLC configuration information.

[0320] In some scenarios, the fourth information contained in the RLC PDU can be followed by other RLC control information, accordingly, whether the RLC PDU contains other RLC control information can be implicitly indicated by the L field. If the L field indicates that the fourth information occupies all the remaining information field of the RLC PDU, the RLC PDU does not contain other RLC control information. Otherwise, if the L field indicates that the fourth information does not occupy all the remaining information field of the RLC PDU, the RLC PDU contains other RLC control information.

[0321] In some scenarios, the last several bits (e.g. 2 bits, 3 bits, 4 bits, etc.) of the D / C field can be a reserved field (i.e. R field). In other scenarios, the last several bits (e.g. 2 bits) of the CPT field can be a reserved field (i.e. R field). At this time, the first information can include the third indication information, the fifth length indication information, a reserved information field, the fifth indication information, and the fourth information.

[0322] Example 3-7: When the third indication information takes the third value, the first information at least includes the third indication information, the sixth length indication information, the fifth length indication information, and the fourth information, and optionally includes the fifth indication information. Hereinafter, taking the transmission of the first information by the RLC PDU as an example, the format of the RLC PDU in the embodiments of the present application is introduced in combination with FIG. 19.

[0323] Referring to FIG. 19, the RLC PDU can include a D / C field, a CPT field, an L field, an F field, and a field for carrying the fourth information. The D / C field can occupy the first bit in Oct1, the CPT field can occupy the second to fourth bits in Oct1, the F field can occupy the fifth bit in Oct1, the L field can occupy the remaining bits in Oct1 and all the bits in Oct2, and the field for carrying the fourth information can occupy all the bits in Oct3-OctN (N is a positive integer greater than or equal to 3).

[0324] Correspondingly, the D / C field is used to carry the fifth indication information, the F field is used to carry the sixth length indication information, the L field is used to carry the fifth length indication information, and the CPT field is used to carry the third indication information.

[0325] The third indication information described above is used to indicate whether the RLC layer control PDU type is control information containing RLC layer configuration information. For example, if the CPT field takes the third value, it indicates that the RLC PDU currently processed contains RLC configuration information, and conversely, if the CPT field takes the seventh value, it indicates that the RLC PDU currently processed does not contain RLC configuration information.

[0326] The sixth length indication information is used to indicate the length of the fifth length indication information, which can be understood as the sixth length indication information being used to indicate the number of bits contained in the L field. For example, when the F field takes the value of '1', the L field occupies 19 bits. For another example, when the F field takes the value of '0', the L field occupies 11 bits.

[0327] In some scenarios, the fourth information contained in the RLC PDU can be followed by other RLC control information, and accordingly, whether the RLC PDU contains other RLC control information can be implicitly indicated by the L field. If the L field indicates that the fourth information occupies all the remaining information fields of the RLC PDU, the RLC PDU does not contain other RLC control information. Otherwise, if the L field indicates that the fourth information does not occupy all the remaining information fields of the RLC PDU, the RLC PDU contains other RLC control information.

[0328] In some scenarios, the last several bits (for example, 2 bits, 3 bits, 4 bits, etc.) of the D / C field can be a reserved field (i.e., R field). In other scenarios, the last several bits (for example, the last 2 bits) of the F field can be a reserved field (i.e., R field). In other scenarios, the last several bits (for example, the last 2 bits) of the CPT field can be a reserved field (i.e., R field). At this time, the first information can include the fifth indication information, the third indication information, the fifth length indication information, the sixth length indication information, the reserved information, and the fourth information.

[0329] Example 3-8: When the third indication information takes the third value, the first information includes the third indication information, the segment indication information, and the fourth information, and optionally includes the fifth indication information. In some scenarios, the first information can further include the segment offset indication information SO. Hereinafter, taking the transmission of the first information by the RLC PDU as an example, the format of the RLC PDU in the embodiments of the present application is introduced in combination with FIG. 20A and FIG. 20B.

[0330] Referring to FIG. 20A, the RLC PDU can include the D / C field, the CPT field, the SI field, and a field used to carry the fourth information. The D / C field can occupy the first bit in Oct1, the CPT field can occupy the second to fourth bits in Oct1, the SI field can occupy the fifth to sixth bits in Oct1, and the field used to carry the fourth information can occupy the remaining bits in Oct1 and all bits in Oct2-OctN (N is a positive integer greater than or equal to 2).

[0331] Correspondingly, the D / C field is used to carry the fifth indication information, the SI field is used to carry the segment indication information, and the CPT field is used to carry the third indication information.

[0332] In some scenarios, if the SI field indicates that the RLC PDU carries one or more of the following: the RLC PDU carries complete RLC layer configuration information, the RLC PDU carries the first segment of complete RLC layer configuration information, and the RLC PDU carries the last segment of complete RLC layer configuration information, the structure of the RLC PDU can refer to FIG. 20A, and accordingly, the terminal device can decode according to the format shown in FIG. 20A.

[0333] Referring to FIG. 20B, the RLC PDU can include a D / C field, a CPT field, an SI field, an SO field, and a field for carrying fourth information. Among them, the D / C field can occupy the first bit in Oct1, the CPT field can occupy the second to fourth bits in Oct1, the SI field can occupy the fifth to sixth bits in Oct1, and at this time, the remaining bits in Oct1 are reserved as a reserved field (R field). The SO field occupies Oct2-Oct3, and the field for carrying the fourth information can occupy all bits in Oct4-OctN (N is a positive integer greater than or equal to 4).

[0334] Accordingly, the D / C field is used to carry the fifth indication information, the SI field is used to carry the segment indication information, the SO field is used to carry the segment offset information, and the CPT field is used to carry the third indication information.

[0335] In some embodiments, the SO field can occupy one or more of the following number of bits: 10 bits; 16 bits; 18 bits.

[0336] In some scenarios, if the SI field indicates that the RLC PDU carries an intermediate segment of complete RLC layer configuration information, the structure of the RLC PDU can refer to FIG. 20B, and accordingly, the terminal device can decode according to the format shown in FIG. 20B.

[0337] In some scenarios, the last few bits (for example, 2 bits, 3 bits, 4 bits, etc.) of the D / C field can be a reserved field (i.e., R field). In other scenarios, the last few bits (for example, the last 2 bits) of the SI field can be a reserved field (i.e., R field), for example, referring to FIG. 20B, the last 2 bits of the SI field can be a R field. In other scenarios, the last few bits (for example, the last 1 bit) of the CPT field can be a reserved field (i.e., R field). In other scenarios, the last few bits (for example, the last 1 bit) of the SO field can be a reserved field (i.e., R field). In the above cases, the first information can include the fifth indication information, the third indication information, the SI, the reserved information, and the fourth information. Optionally, the first information can also include the SO.

[0338] It should be noted that the position relationship between the SI field and the SO field is only exemplarily illustrated in FIG. 20B, and the embodiments of the present application do not limit this. For example, the last several bits (such as 2 bits) of the SI field can be used as the SO field.

[0339] In some scenarios, the first information can further include the SO.

[0340] In the following, the format of the RLC PDU in the embodiments of the present application is introduced by taking an example of transmitting the first information through the RLC PDU, as shown in FIGS. 21A and 21B.

[0341] As shown in FIG. 21A, the RLC PDU can include a D / C field, a CPT field, an SI field, an L field, and a field for carrying the fourth information. The D / C field can occupy the first bit in Oct1, the CPT field can occupy the second to fourth bits in Oct1, the SI field can occupy the fifth to sixth bits in Oct1, the L field occupies the remaining bits in Oct1 and all bits in Oct2, and the field for carrying the fourth information can occupy all bits in Oct3-OctN (N is a positive integer greater than or equal to 3).

[0342] Correspondingly, the D / C field is used to carry the fifth indication information, the SI field is used to carry the segmentation indication information, the L field is used to carry the fifth length indication information, and the CPT field is used to carry the third indication information.

[0343] In some scenarios, the fourth information contained in the RLC PDU can further include other RLC control information, and correspondingly, whether the RLC PDU contains other RLC control information can be implicitly indicated by the L field. If the L field indicates that the fourth information occupies all the remaining information fields of the RLC PDU, the RLC PDU does not contain other RLC control information. Otherwise, if the L field indicates that the fourth information does not occupy all the remaining information fields of the RLC PDU, the RLC PDU contains other RLC control information.

[0344] In some scenarios, if the SI field indicates that the RLC PDU carries one or more of the following: the RLC PDU carries complete RLC layer configuration information, the first segment of the RLC PDU carrying complete RLC layer configuration information, and the last segment of the RLC PDU carrying complete RLC layer configuration information, the structure of the RLC PDU can refer to FIG. 21A, and accordingly, the terminal device can decode according to the format shown in FIG. 21A.

[0345] Referring to FIG. 21B, the RLC PDU can include a D / C field, a CPT field, an SI field, an SO field, an L field, and a field for carrying fourth information. Among them, the D / C field can occupy the first bit in Oct1, the CPT field can occupy the second to fourth bits in Oct1, the SI field can occupy the fifth to sixth bits in Oct1, at this time, the remaining bits in Oct1 are used as a reserved (R field). The SO field occupies Oct2-Oct3, the L field occupies Oct4-Oct5, and the field for carrying the fourth information can occupy all bits in Oct6-OctN (N is a positive integer greater than or equal to 6).

[0346] Accordingly, the D / C field is used to carry fifth indication information, the SI field is used to carry segment indication information, the SO field is used to carry segment offset indication information, the L field is used to carry fifth length indication information, and the CPT field is used to carry third indication information.

[0347] In some scenarios, the fourth information contained in the RLC PDU can also include other RLC control information, and accordingly, whether the RLC PDU contains other RLC control information can be indicated implicitly by the L field. If the L field indicates that the fourth information occupies all the remaining information fields of the RLC PDU, the RLC PDU does not contain other RLC control information. Otherwise, if the L field indicates that the fourth information does not occupy all the remaining information fields of the RLC PDU, the RLC PDU contains other RLC control information.

[0348] In some scenarios, if the SI field indicates that the RLC PDU carries an intermediate segment of complete RLC layer configuration information, the structure of the RLC PDU can refer to FIG. 21B, and accordingly, the terminal device can decode according to the format shown in FIG. 21B.

[0349] In some scenarios, the last several bits (e.g., 2 bits, 3 bits, 4 bits, etc.) of the D / C field can be a reserved field (i.e., R field). In other scenarios, the last several bits (e.g., the last 2 bits) of the SI field can be a reserved field (i.e., R field), e.g., see FIG. 21B, the last 2 bits of the SI field can be a R field. In other scenarios, the last several bits (e.g., the last 1 bit) of the CPT field can be a reserved field (i.e., R field). In this case, the first information can include the fifth indication information, the third indication information, the SI, the reserved information, the fifth length indication information, and the fourth information. Optionally, the first information can further include the SO.

[0350] In addition, the position relationship between the SI field and the SO field is only illustratively shown in FIG. 21B, and embodiments of the present application do not limit this. For example, the last several bits (e.g., 2 bits) of the SI field can be used as the SO field.

[0351] Example 3-10: When the third indication information has a third value, the first information includes the third indication information, the sixth length indication information, the segment indication information, the fifth length indication information, and the fourth information, and optionally includes the fifth indication information. In some scenarios, the first information can further include the SO.

[0352] In the following, the format of the RLC PDU is introduced by taking an example of transmitting the first information through the RLC PDU, according to FIGS. 22A and 22B. Referring to FIG. 22A, the RLC PDU can include a D / C field, a CPT field, an SI field, an L field, an F field, and a field for carrying the fourth information. The D / C field can occupy the first bit in Oct1, the CPT field can occupy the second to fourth bits in Oct1, the F field occupies the fifth bit in Oct1, the SI field can occupy the sixth to seventh bits in Oct1, the L field occupies the remaining bits in Oct1 and all bits in Oct2, and the field for carrying the fourth information can occupy all bits in Oct3-OctN (N is a positive integer greater than or equal to 3).

[0353] Correspondingly, the D / C field is used to carry the fifth indication information, the F field is used to carry the sixth length indication information, the SI field is used to carry the segment indication information, the L field is used to carry the fifth length indication information, and the CPT field is used to carry the third indication information.

[0354] For example, when the sixth length indication information has a value of ‘1’, the protocol stipulates that the fifth length indication information occupies 16 or 17 bits. When the sixth length indication information has a value of ‘0’, the protocol stipulates that the fifth length indication information occupies 8 or 9 bits.

[0355] In some scenarios, the fourth information contained in the RLC PDU can be followed by other RLC control information, accordingly, whether the RLC PDU contains other RLC control information can be implicitly indicated by the L field. If the L field indicates that the fourth information occupies all the remaining information fields of the RLC PDU, the RLC PDU does not contain other RLC control information. Otherwise, if the L field indicates that the fourth information does not occupy all the remaining information fields of the RLC PDU, the RLC PDU contains other RLC control information.

[0356] In some scenarios, if the SI field indicates that the RLC PDU is one or more of the following: the RLC PDU carries complete RLC layer configuration information, the RLC PDU carries the first segment of complete RLC layer configuration information, the RLC PDU carries the last segment of complete RLC layer configuration information, the structure of the RLC PDU can refer to FIG. 22A, and accordingly, the terminal device can decode according to the format shown in FIG. 22A.

[0357] Referring to FIG. 22B, the RLC PDU can include a D / C field, an F field, a CPT field, an SI field, an SO field, an L field, and a field for carrying fourth information. Among them, the D / C field can occupy the first bit in Oct1, the CPT field can occupy the second to fourth bits in Oct1, the F field occupies the fifth bit in Oct1, the SI field can occupy the sixth to seventh bits in Oct1, at this time, the remaining bits in Oct1 are reserved as a R field. The SO field occupies Oct2-Oct3, the L field occupies Oct4-Oct5, and the field for carrying the fourth information can occupy all the bits in Oct6-OctN (N is a positive integer greater than or equal to 6).

[0358] Accordingly, the D / C field is used to carry the fifth indication information, the F field is used to carry the sixth length indication information, the SI field is used to carry the segment indication information, the SO field is used to carry the segment offset indication information, the L field is used to carry the fifth length indication information, and the CPT field is used to carry the third indication information.

[0359] For example, when the value of the sixth length indication information is ‘1’, the protocol stipulates that the fifth length indication information occupies 16 bits. When the value of the sixth length indication information is ‘0’, the protocol stipulates that the fifth length indication information occupies 8 bits.

[0360] In some scenarios, the fourth information contained in the RLC PDU can be followed by other RLC control information, accordingly, whether the RLC PDU contains other RLC control information can be implicitly indicated by the L field. If the L field indicates that the fourth information occupies all the remaining information fields of the RLC PDU, the RLC PDU does not contain other RLC control information. Otherwise, if the L field indicates that the fourth information does not occupy all the remaining information fields of the RLC PDU, the RLC PDU contains other RLC control information.

[0361] In some scenarios, if the SI field indicates that the current RLC PDU carries an intermediate segment of the complete RLC layer configuration information, the structure of the current RLC PDU can refer to FIG. 22B, accordingly, the terminal device can decode according to the format shown in FIG. 22B.

[0362] In some scenarios, the last several bits (for example, 2 bits, 3 bits, 4 bits, etc.) of the D / C field can be a reserved field (i.e., R field). In other scenarios, the last several bits (for example, the last 1 bit) of the SI field can be a reserved field (i.e., R field), for example, refer to FIG. 22B, the last 1 bit of the SI field can be an R field. In other scenarios, the last several bits (for example, the last 2 bits) of the CPT field can be a reserved field (i.e., R field). At this time, the first information can include the fifth indication information, the third indication information, the sixth length indication information, the segment indication information SI, the reserved information, the fifth length indication information, and the fourth information. Optionally, the first information can further include SO.

[0363] In addition, the position relationship between the SI field and the SO field in FIG. 22B is only exemplary, and the embodiments of the present application are not limited thereto. For example, the last several bits (such as 1 bit) of the SI field can be used as the SO field.

[0364] It should be noted that in the scheme of the embodiments of the present application, the RLC PDU can not contain the D / C field, that is, the fourth information does not contain the fifth indication information, at this time, it can be understood that there is no data to be delivered to the upper protocol layer of the RLC layer at this time. This scenario can be applicable to zero-power devices, IoT devices, etc.

[0365] Embodiment 4: The first protocol layer is a PDCP layer.

[0366] In the embodiments of the present application, the PDCP layer of the network device can configure the PDCP layer of the terminal device through the first information. In this way, after receiving the first information, the terminal device can directly submit the first information to the PDCP layer (for example, from the physical layer to the MAC layer, from the MAC layer to the RLC layer, and from the RLC layer to the PDCP layer) for processing (for example, parsing) and configuration application. Compared with the traditional configuration process processing mode (regardless of the protocol layer to which the configuration information is configured, the configuration information of the protocol layer needs to be submitted to the RRC layer layer by layer for processing, and then the RRC layer transmits the processed configuration information back to the configured protocol layer for configuration), the configuration method provided in the present application can help to reduce the time delay required for configuring the PDCP layer, so as to improve the efficiency of configuring the PDCP layer. On the other hand, the configuration of the PDCP layer in the terminal device is configured and managed by the PDCP layer in the network device, which can significantly reduce the dependence of the configuration process on the RRC protocol layer, and is conducive to realizing a simple RRC protocol layer function.

[0367] In some implementations, the first information includes fourth indication information and / or fifth information, wherein the fourth indication information is used to indicate the PDCP control PDU type, and the fifth information is used to carry the configuration information of the PDCP layer.

[0368] Taking the first information including the fifth information as an example, in some implementations, the control PDU of the PDCP layer can include the configuration information of the PDCP layer.

[0369] In the embodiments of the present application, the configuration information of the PDCP layer is not limited. In some implementations, the configuration information of the PDCP layer can include one or more of the following: header compression function related configuration, reordering function related configuration, PDU discard function related configuration, and security function related configuration.

[0370] In some implementations, the PDCP configuration information is used to control the PDCP function, and after being parsed by the PDCP, the PDCP configuration information can be directly applied by the PDCP, for example: header compression function related configuration parameters, without the need to combine the configuration provided by the RRC protocol layer. In the traditional technology, the PDCP cannot directly parse the PDCP configuration information, and all PDCP configuration information is parsed by the RRC protocol layer and then transmitted to the PDCP through the interlayer interaction process. Although the PDCP protocol layer also has some control PDUs, for example: status report PDU, there is no control PDU directly containing the PDCP layer configuration, which is essentially different from the configuration information in the embodiments of the present application.

[0371] In some embodiments, the fifth information further comprises message type indication information and / or group indication information, which helps the terminal device to confirm the format used to decode the PDCP layer configuration information carried in the fifth information. In addition, the fifth information comprising the message type indication information and / or the group indication information can further increase the flexibility of configuration, for example, a small number of parameters can be indicated by the message type indication information and / or the group indication information to be configured incrementally while most of the parameters are not reconfigured, thereby saving the overhead of the reconfiguration process.

[0372] In some embodiments, the message type indication information is used to indicate the message type to which the PDCP layer configuration information included in the fifth information belongs. In the embodiments of the present application, the implementation of the message type indication information is not limited. In some embodiments, the message type indication information can be implemented by a choice function or identification information indication.

[0373] In some embodiments, different values of the message type indication information can correspond to different message types, or in other words, the message type indication information is used to indicate which PDCP layer message the PDCP layer configuration information included in the fifth information belongs to. For example, the PDCP layer configuration information can be divided into 5 message types, at this time, the message type indication information can occupy 3 bits, each message type corresponds to a value, that is, message type 1 corresponds to the value '000', message type 2 corresponds to the value '001', message type 3 corresponds to the value '010', message type 4 corresponds to the value '011', and message type 5 corresponds to the value '100'.

[0374] In the embodiments of the present application, the number of bits occupied by the message type indication information is not limited. For example, the message type indication information can occupy 3 bits. For another example, the message type indication information can occupy 2 bits. In addition, in the embodiments of the present application, the content included in different message types can be predefined.

[0375] In some embodiments, the group indication information is used to indicate the parameter group to which the PDCP layer configuration information included in the fifth information belongs, or in other words, the group indication information is used to indicate which group of parameters is intended to be configured in this round of configuration process. In the embodiments of the present application, the implementation of the group indication information is not limited. In some embodiments, the group indication information can be implemented by a choice function or identification information indication.

[0376] In some implementations, different values of the group indication information can correspond to different groups. For example, the PDCP layer configuration information can be divided into 5 groups, and in this case, the group indication information can occupy 3 bits, and each group of configuration information corresponds to a value, i.e., group 1 corresponds to the value '000', group 2 corresponds to the value '001', group 3 corresponds to the value '010', group 4 corresponds to the value '011', and group 5 corresponds to the value '100'.

[0377] In the embodiments of the present application, the number of bits occupied by the group indication information is not limited. For example, the group indication information can occupy 3 bits. For another example, the group indication information can occupy 2 bits. In addition, in the embodiments of the present application, the content contained in different groups can be predefined.

[0378] In the embodiments of the present application, the implementation mode of the fifth information is not limited. The following will be introduced in combination with Examples 4-1 to 4-4. It should be understood that the following mainly introduces the implementation mode of the fifth information, and the meaning of the information contained in the fifth information can be referred to the introduction in the above.

[0379] Example 4-1: The fifth information includes PDCP layer configuration information.

[0380] Example 4-2: The fifth information includes message type indication information and PDCP layer configuration information, wherein the message type indication information is used to indicate which type of message the current configuration process intends to configure.

[0381] For example, the PDCP layer defines two message types: a first message type and a second message type, and in this case, in order to let the terminal device know the PDCP layer configuration information of the current configuration, the fifth information can carry the message type indication information, i.e., the message type indication information is used to indicate that the PDCP layer configuration information of the current configuration is the parameter in the first message type.

[0382] Example 4-3: The fifth information includes group indication information and PDCP layer configuration information, wherein the group indication information is used to indicate which group of parameters the current configuration process configures.

[0383] For example, the PDCP layer defines two groups of parameters, and in this case, in order to let the terminal device know the PDCP layer configuration information of the current configuration, the fifth information can carry the group indication information, i.e., the group indication information can be used to indicate that the PDCP layer configuration information of the current configuration is the first group of parameters.

[0384] Example 4-4: The fifth information includes message type indication information, group indication information and PDCP layer configuration information, wherein the message type indication information is used to indicate which type of message the group of parameters the current configuration process intends to configure belongs to, and the group indication information is used to indicate which group of parameters in the message the current configuration process intends to configure.

[0385] For example, the PDCP layer defines two message types, wherein the first message type contains two groups of parameters, and the second message type contains three groups of parameters. At this time, in order to make the terminal device clear the PDCP layer configuration information configured in this round, the fifth information can carry message type indication information and group indication information, that is, the message type indication information and the group indication information indicate that the PDCP layer configuration information configured in this round is the first group of parameters in the first message type.

[0386] The fifth information in the embodiments of the present application is introduced above, and the fourth indication information in the embodiments of the present application is introduced below.

[0387] For example, when the fourth indication information takes the fourth value, the first information further includes the fifth information, and at this time, the PDCP control PDU type indicated by the fourth indication information is a control PDU containing the configuration information of the PDCP layer.

[0388] That is, the fourth indication information is used to indicate the PDCP control PDU type (CPT), and accordingly, the fourth indication information can be carried in the CPT field. For example, the CPT field takes the value of ‘000’ to indicate that the PDCP PDU currently decoded is a STATUS PDU, and the CPT field takes the value of ‘001’ to indicate that the PDCP PDU currently decoded is a PDCP configuration PDU.

[0389] In the embodiments of the present application, the value of the fourth value is not limited. For example, when the fourth indication information takes the value of ‘001’, the PDCP control PDU type indicated by the fourth indication information is a control PDU containing the configuration information of the PDCP layer. Of course, in the embodiments of the present application, the value of the fourth value can also be ‘010’.

[0390] In some implementations, the value of the fourth value can be predefined, for example, the value of the fourth value can be predefined by a protocol.

[0391] In some embodiments, the fourth indication information is used to indicate a PDCP control PDU type. In some embodiments, the fourth indication information is used to indicate a PDCP control PDU type, and the first information includes the fifth information when the fourth indication information is of a seventh value. In some embodiments, the fourth indication information is used to indicate a PDCP control PDU type, and the first information does not include the fifth information when the fourth indication information is of an eighth value. In some embodiments, the fourth indication information is used to indicate a PDCP control PDU type, and the first information includes the fifth information when the fourth indication information is of a ninth value.

[0392] In some embodiments, the eighth value is predefined.

[0393] In some embodiments, the eighth value is predefined.

[0394] In some embodiments, the fourth indication information is used to indicate a PDCP control PDU type.

[0395] In some embodiments, the fourth indication information is carried in a PDU type field, which will be described below in connection with FIG. 23.

[0396] In some embodiments, the first information further includes segmentation indication information and / or seventh length indication information. For example, the first information further includes the segmentation indication information and the seventh length indication information. For another example, the first information further includes the segmentation indication information. For another example, the first information further includes the seventh length indication information.

[0397] In some embodiments, the seventh length indication information is used to indicate a length of the fifth information, which is helpful to provide at least two kinds of PDCP layer control information with different lengths through the first information. For example, through flexible indication of the seventh length indication information, it can be determined that the first information can only include the fifth information, or one piece of first information can include the fifth information and other PDCP layer control information. Compared with a method without the seventh length indication information, the indication of the first information including the seventh length indication information is more flexible.

[0398] For example, the seventh length indication information is used to indicate a number of bytes occupied by the fifth information. For another example, the seventh length indication information is used to indicate a number of bits occupied by the fifth information.

[0399] In some embodiments, the first length indication information can be carried in the L field. Details are described below with reference to FIG. 23.

[0400] In some embodiments, the first information further includes eighth length indication information, which is used to indicate the length of the seventh length indication information, and helps to improve the flexibility of setting the length occupied by the seventh length indication information. For example, the eighth length indication information is used to indicate the number of bytes occupied by the seventh length indication information. For another example, the eighth length indication information is used to indicate the number of bits occupied by the seventh length indication information.

[0401] In the embodiments of the present application, the manner in which the eighth length indication information indicates the length of the seventh length indication information is not limited. In some embodiments, the eighth length indication information can directly carry the actual length of the seventh length indication information. In other embodiments, the value of the eighth length indication information corresponds to the actual length of the seventh length indication information one by one. For example, when the value of the eighth length indication information is ‘1’, the protocol stipulates that the seventh length indication information can occupy 20 bits. For another example, when the value of the eighth length indication information is ‘0’, the protocol stipulates that the seventh length indication information can occupy 12 bits.

[0402] In some embodiments, the eighth length indication information can be carried in the F field. Details are described below with reference to FIG. 23.

[0403] In other embodiments, the length of the seventh length indication information can be predefined, which helps to reduce the number of bits for transmitting the first information. For example, the length of the seventh length indication information can be stipulated in the protocol to occupy 7 bits. For another example, the length of the seventh length indication information can be stipulated in the protocol to occupy 12 bits. For another example, the length of the seventh length indication information can be stipulated in the protocol to occupy 15 bits. For another example, the length of the seventh length indication information can be stipulated in the protocol to occupy 20 bits.

[0404] In other embodiments, the length of the seventh length indication information is configured by the network device, which helps to improve the flexibility of setting the length of the seventh length indication information. For example, the network device can configure the length of the seventh length indication information through dedicated signaling. For another example, the network device can configure the length of the seventh length indication information to occupy 4 bits through dedicated signaling. For another example, the network device can configure the length of the seventh length indication information to occupy 12 bits through dedicated signaling. For another example, the network device can configure the length of the seventh length indication information to occupy 18 bits through dedicated signaling. For another example, the network device can configure the length of the seventh length indication information to occupy 20 bits through dedicated signaling.

[0405] In some embodiments, the first information can further include fifth indication information, where the fifth indication information is used to indicate whether the information carried by the first information is data type information or control type information.

[0406] In some embodiments, the fifth indication information can be carried in a D / C field, which will be described below in connection with FIG. 23.

[0407] In some embodiments, if the fifth indication information indicates that the information carried by the first information is data type information, it means that the first information does not include the fifth information, or in other words, the first information does not need to be parsed by the PDCP. It should be understood that in the embodiments of the present application, if the fifth indication information indicates that the information carried by the first information is data type information, the first information can carry application layer data type information or carry RRC layer configuration information and / or non-configuration type instruction information.

[0408] In some embodiments, if the fifth indication information indicates that the information carried by the first information is data type information, the method further includes: the PDCP layer of the terminal device submits information in the fifth information that cannot be parsed by the PDCP layer to the RRC layer of the terminal device for processing.

[0409] In other embodiments, if the fifth indication information indicates that the information carried by the first information is control type information, the first information can include the fifth information. At this time, it can be further determined based on the fourth indication information whether the PDCP control PDU type is a control PDU that includes configuration information of the PDCP layer. That is, in this way, the first information can include the fifth indication information and the fourth indication information. Of course, in the embodiments of the present application, if the fifth indication information indicates that the information carried by the first information is control type information, the first information includes the fifth information. At this time, it can be considered that the PDCP control PDU type only exists in the control PDU that includes the configuration information of the PDCP layer. That is, in this way, the first information can include the fifth indication information and does not include the fourth indication information.

[0410] In order to facilitate understanding, the first information in the embodiments of the present application will be described below in connection with Examples 4-5. It is assumed that Oct represents a byte, and one byte occupies 8 bits. It should be understood that the following mainly describes the implementation of the first information, and the meaning of the information included in the first information can be referred to the description above.

[0411] Example 4-5: When the fourth indication information has a fourth value, the first information at least includes the fourth indication information and the fifth information, and optionally includes the fifth indication information. The format of the PDCP PDU in the embodiments of the present application will be described below in connection with FIG. 23 by taking the transmission of the first information through the PDCP PDU as an example.

[0412] Referring to FIG. 23, the PDCP PDU can include a D / C field, a PDU type field, and a field for carrying the fifth information. The D / C field can occupy the first bit in Oct1, the PDU type field can occupy the second to fourth bits in Oct1, and the field for carrying the fifth information can occupy all bits in Oct2-OctN (N is a positive integer greater than or equal to 2).

[0413] Correspondingly, the D / C field is used to carry the fifth indication information, and the PDU type field is used to carry the fourth indication information, which is used to indicate whether the PDCP layer control PDU type includes the configuration information of the PDCP layer. For example, if the PDU type field takes the fourth value, it indicates that the PDCP PDU currently processed includes the configuration information of the PDCP layer, and conversely, if the PDU type field takes the eighth value, it indicates that the PDCP PDU currently processed does not include the configuration information of the PDCP layer.

[0414] In some scenarios, the last several bits (for example, 2 bits, 3 bits, 4 bits, etc.) of the PDU type field can be a reserved field (i.e., R field), and at this time, the first information can include the fourth indication information, the reserved information field, the fifth indication information, and the fifth information.

[0415] It should be noted that in the scheme of the embodiments of the present application, the PDCP PDU can not include the D / C field, that is, the fifth information does not include the fifth indication information, at this time, it can be understood that there is no data to be submitted to the upper protocol layer of the PDCP layer for processing. This scenario can be applicable to zero-power devices, IoT devices, etc.
