[0080] To better understand the data packet transmission method proposed in this disclosure, the network architecture used in some embodiments of this disclosure will be described below.

[0081] The technical solutions of some embodiments of this disclosure can be applied to various communication systems, such as: Global System for Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Universal Mobile Telecommunications System (UMTS) system, Enhanced Data Rate for GSM Evolution (EDGE) system, and Worldwide Interoperability for Microwave Access (WiMAX) system.

Some embodiments of this disclosure do not limit this.

[0082] The following description, with reference to Figure 1, illustrates an application scenario of some embodiments of this disclosure. Figure 1 is a schematic diagram of a network architecture provided by some embodiments of this disclosure. As shown in Figure 1, the network architecture can be, for example, a non-roaming architecture. This network architecture may include the following devices, network elements, and networks:

[0083] 1. Terminal equipment: can be called user equipment (UE), terminal, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, wireless communication equipment, terminal agent or terminal device, etc. The UE can also be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, in-vehicle device or wearable device, terminal device in future 6G networks, or terminal device in future evolved public land mobile network (PLMN), etc. It can also be an end device, logical entity, or smart device, such as a mobile phone, a smart terminal, for example, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. Wireless terminals in the home (or Internet of Things (IoT) devices), such as sensors, electricity meters, and water meters, are examples of such devices. Some embodiments of this disclosure are not limited to this. In some embodiments of this disclosure, for example in the industrial field, the terminal device can be a customer premises equipment (CPE). An industrial terminal can be a device that specifically performs industrial control operations, such as a temperature sensor or a robotic arm. These industrial terminals typically do not have 5G access capabilities and need to be connected to a 5G-enabled CPE, so that the industrial terminal can indirectly access the 5G network through the CPE. Alternatively, the terminal device can be a combination of industrial terminals and CPEs that may evolve in the future; specifically, it can be understood as an industrial terminal with 5G capabilities, etc. This disclosure does not limit this.

[0084] 2. Radio Access Network (RAN): Provides network access functionality for authorized terminals in a specific area and can use transmission tunnels of different quality depending on the terminal's level and service requirements. Access networks can employ different access technologies. Currently, there are two types of radio access technologies: 3rd Generation Partnership Project (3GPP) access technologies (such as those used in 4G and 5G systems) and non-3GPP access technologies. 3GPP access technologies refer to access technologies that conform to 3GPP standards and specifications. Access networks using 3GPP access technologies are called RANs, and the access network equipment in 5G systems is called next-generation node base stations (gNBs). Non-3GPP access technologies refer to access technologies that do not conform to 3GPP standards and specifications, such as air interface technologies represented by access points (APs) in Wi-Fi.

[0085] An access network that implements access network functions based on wireless communication technology can be called a RAN. The RAN manages radio resources, provides access services to terminals, and forwards control signals and terminal data between the terminal and the core network. An RAN can be, for example, a base station (NodeB), an evolved NodeB (eNB or eNodeB), a base station (gNB) in a 5G mobile communication system, a base station in a future mobile communication system, or an access point (AP) in a Wi-Fi system. It can also be a radio controller in a cloud radio access network (CRAN) scenario, or the access network device can be a relay station, access point, vehicle-mounted equipment, wearable devices, or access network equipment in future 6G networks or future evolved PLMN networks. The embodiments disclosed herein do not limit the specific technologies or equipment forms used in the wireless access network devices.

[0086] 3. Access and Mobility Management Function (AMF) Entity: Primarily used for mobility management and access management, it can implement functions of the Mobility Management Entity (MME) other than session management, such as lawful interception or access authorization / authentication. In some embodiments of this disclosure, it can be used to implement the functions of the access and mobility management network element.

[0087] 4. Session Management Function (SMF) Entity: Primarily used for session management, allocation and management of Internet Protocol (IP) addresses for terminal devices, selection and management of user plane functions, policy control and charging function interface endpoints, and downlink data notification, etc. In some embodiments of this disclosure, it can be used to implement the functions of the session management network element.

[0088] 5. User plane function (UPF) entity: also known as data plane gateway. It can be used for packet routing and forwarding, or for quality of service (QoS) processing of user plane data. User data can access the data network (DN) through this network element. In some embodiments of this disclosure, it can be used to implement the functions of a user plane network element.

[0089] 6. Data Network (DN): A network used to provide data transmission. Examples include carrier networks, the Internet, and third-party service networks.

[0090] 7. Network Exposure Function (NEF) Entity: Used to securely expose services and capabilities provided by 3GPP network functions to the outside world.

[0091] 8. Policy control function (PCF) entity: responsible for policy control functions such as billing at the session and service flow level, QoS bandwidth guarantee and mobility management, and terminal device policy decision-making.

[0092] 9. Unified Data Management (UDM) entity: Used to handle terminal device identification, access authentication, registration, and mobility subscription management, etc.

[0093] 10. Application Function (AF) Entity: Used for application data routing, accessing network open function elements (NFIs), and interacting with the policy framework for policy control. AFs can convey application-side requests to the network side, such as QoS requirements or user state event subscriptions. As an application function entity, an AF can also undergo authorization processing via the NEF when interacting with the core network. For example, it can directly send a request message to the NEF, which determines whether the AF is allowed to send the request message. If the verification is successful, the NEF will forward the request message to the corresponding PCF or UDM.

[0094] 11. Unified Data Repository (UDR) Entity: Used for unified data warehousing functions. Primarily responsible for storing and retrieving data types such as contract data, strategy data, and application data.

[0095] It should be understood that the network architectures described above for some embodiments of this disclosure are merely illustrative examples of network architectures described from the perspective of traditional point-to-point architectures and service-oriented architectures. The network architectures applicable to some embodiments of this disclosure are not limited thereto, and any network architecture capable of implementing the functions of the above-described network elements is applicable to some embodiments of this disclosure.

[0096] It should also be understood that the AMF, SMF, UPF, DN, NEF, PCF, UDM, AF, and UDR entities shown in Figure 1 can be understood as network elements in the core network used to implement different functions, such as network slices that can be combined as needed. These core network elements can be independent devices or integrated into the same device to implement different functions; this application does not limit this.

[0097] In some embodiments of this disclosure, the network device can be an access network device, such as the RAN in Figure 1. Alternatively, in some embodiments of this disclosure, the network device can be a core network device, such as one of the AMF entity, SMF entity, UPF entity, DN entity, NEF entity, PCF entity, UDM entity, AF entity, and UDR entity in Figure 1. In some implementations, the network device in some embodiments of this disclosure can also be a network management entity or a third-party device.

[0098] Please refer to Figure 2, which is a flowchart illustrating a data packet transmission method according to some embodiments of this disclosure. As shown in Figure 2, the data packet transmission method of this embodiment includes, but is not limited to, the following steps:

[0099] 201, The terminal device determines at least one data packet mapped to the first transmission unit.

[0100] In this embodiment, at least one data packet mapped to the first transmission unit has at least one identical data characteristic. For ease of description, this at least one data packet is referred to as N data packets, where N is a natural number. That is, N data packets are mapped to the first transmission unit, and these N data packets can also be referred to as a data group or a data block. It is understood that the number of data packets mapped to different transmission units can be the same or different; here, N data packets mapped to the first transmission unit are used as an example. The terminal device maps data packets to transmission units according to the data characteristics of the data packets to be sent. In some embodiments of this disclosure, data packets mapped to one of the transmission units are used as an example; this transmission unit is called the first transmission unit. The mapping method for data packets mapped to other transmission units can refer to the first transmission unit.

[0101] In some embodiments of this disclosure, the N data packets mapped to the first transmission unit have the same at least one data feature. The at least one data feature may include at least one of the following 1 to 7 data features:

[0102] 1. The encoding method of the data in the data packet;

[0103] The encoding method of data in a data packet can also be called the format of data in a data packet. Encoding methods can be at least one of the following: Hypertext Transfer Protocol (HTTP), Quic encoding, ASN.1 encoding, etc.

[0104] In response to at least one data feature including the encoding method of data in a data packet, the data in the N data packets mapped to the first transmission unit have the same encoding method.

[0105] 2. The data type in the data packet;

[0106] Data types can be at least one of the following: AI data, perception data, road test data, Quality of Experience (QoE) measurement data, etc., and may also include other data types.

[0107] In response to at least one data feature including the data type of the data in the data packet, the data types of the data in the N data packets mapped to the first transmission unit are the same.

[0108] 3. The content of at least one field in the header of the data packet;

[0109] The header of a data packet may include at least one of the following fields: source address field, destination address field, port number field, etc.

[0110] In response to at least one data feature including the content of at least one field in the header of a data packet, the headers of N data packets mapped to the first transmission unit contain the same content for that at least one field. For example, if at least one field includes a destination address field, it can be understood that the destination address field in the headers of the N data packets mapped to the first transmission unit contains the same content.

[0111] 4. Identification of data collection configuration information;

[0112] Data collection configuration information is used to configure the measurement parameters of the data in the data packet. For example, the data collection configuration information can configure at least one of the following measurement parameters: measurement target, measurement period, etc. The identifier of the data configuration information is used to identify the data collection configuration information.

[0113] In response to at least one data feature including an identifier of data collection configuration information, the data mapped to the N data packets of the first transmission unit is obtained by measuring using the same data collection configuration information.

[0114] 5. Identifiers for data reporting configuration information;

[0115] Data reporting configuration information is used to configure the reporting parameters of data in data packets. For example, data reporting configuration information can configure at least one of the following reporting parameters: reporting period, reporting event, etc. The identifier of data reporting configuration information is used to identify the data reporting configuration information.

[0116] In response to at least one data feature including an identifier for data reporting configuration information, the data mapped to the N data packets of the first transmission unit is reported based on the same data reporting configuration information.

[0117] 6. Identification of the data collection server;

[0118] The data collection server is the destination server for the data packets, and the identifier of the data collection server can be an Internet Protocol (IP) address.

[0119] In response to at least one data feature including the identifier of the data collection server, the destination servers of the N data packets mapped to the first transmission unit are the same, that is, the N data packets are sent to the same server.

[0120] 7. Identification of data collection tasks.

[0121] A data collection task is a task associated with data in a data packet, and the data collection task can define the data to be collected.

[0122] In response to at least one data feature including the identifier of the data collection task, the N data packets mapped to the first transmission unit are data to be collected as defined by the same data collection task.

[0123] The N data packets mapped to the first transmission unit share at least one of the data characteristics 1 to 7 described above. For example, the N data packets may have the same data collection configuration information identifier and the same data type, i.e., items 2 and 4 mentioned above; or the data in the N data packets may have the same encoding method, i.e., item 1 mentioned above; the data in the N data packets may be reported based on the same data reporting configuration information, i.e., item 5 mentioned above; the data in the N data packets may have the same data type, the same destination server, and be data to be collected as defined by the same data collection task, i.e., items 2, 6, and 7 mentioned above; and so on. It will be understood that "at least one data characteristic may include at least one of the data characteristics 1 to 7 mentioned above" encompasses any combination of all seven items mentioned above, and will not be elaborated further here. Thus, the embodiments of this disclosure provide various forms of data characteristics for data packets, thereby facilitating flexible selection of at least one identical data characteristic mapped to the same transmission unit according to actual needs.

[0124] In some embodiments of this disclosure, the first transmission unit may be a first data stream or a first wireless bearer. In response to the first transmission unit being a first data stream, the terminal device determines N data packets mapped to the first data stream, wherein the N data packets mapped to the first data stream have at least one identical data characteristic. In response to the first transmission unit being a first wireless bearer, the terminal device determines N data packets mapped to the first wireless bearer, wherein the N data packets mapped to the first wireless bearer have at least one identical data characteristic.

[0125] 202. The terminal device sends at least one data packet based on the first transmission unit. Correspondingly, the network device receives at least one data packet. Thus, some embodiments of this disclosure map data packets with at least one identical data characteristic to the same transmission unit. During routing, the data packets mapped to the transmission unit can be routed according to the at least one data characteristic, thereby achieving more flexible routing control and more refined Quality of Service (QoS) management.

[0126] A terminal device can send N data packets mapped to a first transmission unit. In response to the first transmission unit being a first data stream, the terminal device can send the N data packets from the first data stream to a second radio bearer mapped to the first data stream. The mapping relationship between the first data stream and the second radio bearer can be configured by the network. Here, embodiments of this disclosure can map data packets with at least one identical data characteristic to the same data stream, thereby transmitting data packets based on the data stream and facilitating the management of data packets within the same data stream. In response to the first transmission unit being a first radio bearer, the terminal device sends the N data packets to the first radio bearer. Here, embodiments of this disclosure can map data packets with at least one identical data characteristic to the same radio bearer, thereby facilitating the routing management of data packets within the same radio bearer.

[0127] In some embodiments, data packets may be transmitted via Service Data Adaptation Protocol (SDAP) Protocol Data Units (PDUs). Optionally, the terminal device generates a corresponding SDAP PDU for each of the N data packets. The header of each SDAP PDU may include an identifier of the first transmission unit and / or an identifier of at least one data feature. The at least one data feature may be the same data feature shared by the N data packets mapped to the first transmission unit, or it may be other data features. The identifier of the data feature included in the header of each SDAP PDU facilitates the network device's routing control of the data packets based on the identifier of the data feature, as described in step 203. Thus, in some embodiments of this disclosure, the header of the SDAP PDU corresponding to each data packet includes an identifier of the first transmission unit and / or an identifier of at least one data feature, which facilitates the network device's routing control of the received SDAP PDU.

[0128] In response to the first transmission unit being a first radio bearer, the network device can be an access network device; in response to the first transmission unit being a first data stream, the network device can be an access network device or a core network device, such as a UPF. In response to the network device being a core network device, the network device can receive the at least one data packet through the access network device.

[0129] 203. A network device forwards at least one data packet based on at least one data characteristic.

[0130] The network device can forward the N data packets based on at least one common data feature that the N data packets mapped to the first transmission unit have.

[0131] For example, network devices can store the correspondence between data features and IP addresses. This correspondence can be between the identifier of a data feature and the IP address. After receiving a data packet, the network device can determine the IP address corresponding to the data feature of the data packet based on the data feature of the data packet and the stored correspondence, and then forward the data packet to the network element or server corresponding to the IP address, thereby enabling flexible routing control.

[0132] In some embodiments of this disclosure, the network device can configure a mapping relationship between the first transmission unit and at least one of the aforementioned data features. This mapping relationship can also be called a mapping rule. The network device can be an access network device, such as a RAN, or a core network device, a third-party device, or a network management entity, etc. The network device in this embodiment can be a different network device or the same network device as the network device in the embodiment of FIG2. This embodiment and the embodiment of FIG2 can be implemented jointly or independently. For example, the first network device configures a mapping relationship between the first transmission unit and at least one of the aforementioned data features, and the second network device forwards at least one data packet based on at least one data feature.

[0133] The terminal device determines N data packets mapped to the first transmission unit based on the mapping relationship between the first transmission unit configured in the network device and at least one data feature, wherein the N data packets mapped to the first transmission unit have the same at least one data feature.

[0134] Optionally, the network device can configure the mapping relationship between the first transmission unit and at least one data feature through the first configuration information. For example, the first configuration information includes the mapping relationship between the first transmission unit and at least one data feature. It is understood that the first configuration information can also configure the mapping relationship between other transmission units and data features. In some embodiments of this disclosure, configuring the mapping relationship between a transmission unit and a data feature is used as an example. The transmission unit is the first transmission unit. The configuration of the mapping relationship between other transmission units and data features can refer to the relevant description of the first transmission unit.

[0135] For example, the first transmission unit is a data stream, and the first configuration information can configure the mapping relationship between data stream 1 and the identifier = 0 of the data collection configuration information, that is, mapping data packets with the identifier = 0 of the data collection configuration information to data stream 1. As another example, the first configuration information can configure the mapping relationship between data stream 2 and AI data types, that is, mapping AI data type data packets to data stream 2.

[0136] For example, the first transmission unit is a radio bearer (RB). The first configuration information can configure the mapping relationship between RB1 and the identifier of the data collection configuration information = 0, that is, the data packets with the identifier of the data collection configuration information = 0 are mapped to RB1. As another example, the first configuration information can configure the mapping relationship between RB2 and AI data types, that is, the data packets of the AI ​​data type are mapped to RB2.

[0137] Thus, in some embodiments of this disclosure, the network device can configure the mapping relationship between transmission units and data features, thereby facilitating the terminal device to map data packets and perform routing management on a unit-by-unit basis, enabling more flexible routing control.

[0138] In some embodiments of this disclosure, the first transmission unit may be one of the at least one transmission units corresponding to the first session. That is, the first session may correspond to at least one transmission unit, and the first transmission unit is one of the at least one transmission units. In some embodiments of this disclosure, the number of sessions configured by the network device for the terminal device is not limited. In one implementation, the network device may configure multiple sessions for the terminal device, and one session may correspond to one protocol entity. The protocol entity may be an SDAP entity, and the SDAP entity corresponding to the session is responsible for mapping or routing the data packets of that session to the radio bearer. In another implementation, the network device may configure one session for the terminal device, meaning all data packets belong to that one session, and correspondingly, that one session corresponds to one protocol entity.

[0139] For example, in response to a transmission unit being a data stream, the first transmission unit is correspondingly a first data stream, and a first session corresponding to at least one transmission unit can be understood as the first session including at least one data stream, and the first data stream being one of the at least one data streams.

[0140] For example, in response to a transmission unit being a radio bearer, the first transmission unit is correspondingly a first radio bearer. At least one transmission unit corresponding to a first session can be understood as the first session corresponding to at least one radio bearer, and the first radio bearer being one of the at least one radio bearers. The first session corresponding to at least one radio bearer can be understood as data packets belonging to the first session being transmitted through the at least one radio bearer.

[0141] In the case where a first session corresponds to at least one transmission unit, and the first transmission unit is one of the at least one transmission units, the following example illustrates the mapping relationship between the first transmission unit corresponding to the first session and at least one data feature configured in the network device:

[0142] In method 1, the network device sends first configuration information, which includes a mapping relationship between a first transmission unit corresponding to a first session and at least one data feature. Correspondingly, the terminal device determines N data packets mapped to the first transmission unit corresponding to the first session based on the first configuration information. Thus, in some embodiments of this disclosure, the network device can configure the mapping relationship between the transmission unit corresponding to the session and the data feature, preserving the existing session concept and requiring minimal modification to existing standard protocols.

[0143] In Method 1, the first configuration information may include a mapping relationship between the identifier of the first session, the identifier of the first transmission unit, and at least one data feature. That is, data packets with the same at least one data feature are mapped to the first transmission unit corresponding to the first session. For example, the first configuration information may configure the mapping relationship between the identifier of the data collection configuration information = 0 and the first transmission unit corresponding to the first session, i.e., data packets with the identifier of the data collection configuration information = 0 are mapped to the first transmission unit corresponding to the first session. The first transmission unit may be a first radio bearer or a first data stream.

[0144] Accordingly, the terminal device can determine N data packets mapped to the first transmission unit corresponding to the first session based on the first configuration information, wherein the N data packets have the same at least one data feature.

[0145] In response to the first transmission unit being a first data stream, the network device can transmit N data packets mapped to the first data stream to a second radio bearer. The second radio bearer is the radio bearer to which the first data stream is mapped. The mapping relationship between the first data stream and the second radio bearer can be configured by the network device. For example, the network device can configure the mapping relationship between the first data stream and the second radio bearer corresponding to the first session. The network device can configure the mapping relationship between the first data stream and the second radio bearer corresponding to the first session through radio resource control (RRC) signaling, media access control (MAC) control element (CE) signaling, downlink control information (DCI), etc.

[0146] In response to the first transmission unit being the first radio bearer, the network device may transmit N data packets mapped to the first radio bearer on the first radio bearer.

[0147] Method 2: The network device sends second configuration information, which includes the mapping relationship between the first session and the first data feature. The network device also sends third configuration information, which includes the mapping relationship between the first transmission unit and the second data feature. Accordingly, the terminal device determines N data packets mapped to the first transmission unit corresponding to the first session based on the second and third configuration information.

[0148] In Method 2, the network device can configure the mapping relationship between sessions and data features, as well as the mapping relationship between transmission units and data features, where the transmission unit is one of at least two transmission units corresponding to the session. Accordingly, determining that data packets mapped to the transmission unit corresponding to the session have the same data features is based on the mapping relationship between the session and data features and the mapping relationship between the transmission unit and data features.

[0149] The following examples illustrate the mapping relationships between a network device configuring a first session and a first data feature, and between a network device configuring a first transmission unit and a second data feature. All data packets mapped to the first session have the same first data feature. This first session corresponds to at least two transmission units; that is, all data packets mapped to these at least two transmission units have the same first data feature. Similarly, the network device configures a mapping relationship between the first transmission unit and the second data feature. This means that all data packets mapped to the first transmission unit have the same second data feature, while data packets mapped to different transmission units corresponding to the first session have different second data features. Based on the mapping relationships between the first session and the first data feature, and between the first transmission unit and the second data feature, it can be concluded that data packets mapped to the first transmission unit corresponding to the first session have the same first and second data features. Thus, in some embodiments of this disclosure, the first data characteristics of data packets in at least two transmission units corresponding to the same session are the same, and the second data characteristics of data packets in different transmission units in the same session are different. This not only allows for the configuration of multiple data characteristics of data packets in the same transmission unit to be the same, but also allows for the implementation of at least one data characteristic of the same session. This facilitates not only routing control and QoS management of data packets in the transmission unit, but also routing control and QoS management of data packets in the same session.

[0150] For example, the first data feature is the identifier of the data collection configuration information, and the second data feature is the data type of the data in the data packet. The network device can configure the mapping relationship between session 1 and the identifier of the data collection configuration information = 1, the network device can configure the mapping relationship between transmission unit 1 and data type 1, and the mapping relationship between transmission unit 2 and data type 2. Session 1 corresponds to transmission unit 1 and transmission unit 2. That is to say, the data packet mapped to the transmission unit 1 corresponding to session 1 has the identifier of the data collection configuration information = 1 and the data type of the data in the data packet is data of data type 1. The data packet mapped to the transmission unit 2 corresponding to session 1 has the identifier of the data collection configuration information = 1 and the data type of the data in the data packet is data of data type 2.

[0151] Optionally, the network device configures the mapping relationship between the first session and the first data feature using second configuration information, and the network device configures the mapping relationship between the first transmission unit and the second data feature using third configuration information. The second configuration information and the third configuration information can be sent using the same or different signaling. Thus, in some embodiments of this disclosure, the network device can independently configure the mapping relationship between the session and the data feature, as well as the mapping relationship between the transmission unit and the data feature, providing greater flexibility in configuration.

[0152] In Method 2, the first data feature and the second data feature are merely examples. The first data feature can be any one of multiple data features that have a mapping relationship with the first session, and the second data feature can be any one of multiple data features that have a mapping relationship with the first transmission unit. The first transmission unit mapped to the first session has the same at least one data feature, which includes both the first data feature and the second data feature.

[0153] In some embodiments, the second data feature may be a subset of the first data feature, wherein the first data feature includes at least one data feature and the second data feature includes at least one data feature. For example, the first data feature includes an identifier of data collection configuration information = 1 and an identifier of data collection configuration information = 2, that is, data packets with identifiers of data collection configuration information = 1 and 2 are mapped to the first session. The second data feature may be an identifier of data collection configuration information = 1, that is, data packets with identifiers of data collection configuration information = 1 are mapped to the first transmission unit corresponding to the first session, and data packets with identifiers of data collection configuration information = 2 are mapped to the second transmission unit corresponding to the first session.

[0154] All embodiments of this disclosure can be executed individually or in combination with other embodiments, and are all considered to be within the scope of protection claimed by this disclosure.

[0205] For a detailed description of Figure 4, please refer to the description of the aforementioned method embodiments, which will not be repeated here.

[0206] Please refer to Figure 5, which is a schematic diagram of a communication device provided in some embodiments of this disclosure. This device is used to implement the functions of a network device in the above method embodiments, or to implement the functions of a terminal device in the above method embodiments. The communication device 1300 can be a network device or a device for a network device. The device for a network device can be a chip system or a chip within the network device. The communication device can also be a terminal device or a device for a terminal device. The device for a terminal device can be a chip system or a chip within the terminal device. The chip system can be composed of chips or can include chips and other discrete components.

[0207] The communication device 1300 includes at least one processor 1320 for implementing the data processing functions of the network device or terminal device in the methods provided in some embodiments of this disclosure. The communication device 1300 may also include a communication interface 1310 for implementing the transmit and receive operations of the network device or terminal device in the methods provided in some embodiments of this disclosure. In some embodiments of this disclosure, the processor 1320 may be a Central Processing Unit (CPU), or it may be other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor may be a microprocessor or any conventional processor. In some embodiments of this disclosure, the communication interface 1310 may be a transceiver, circuit, bus, module, or other type of communication interface for communicating with other devices via a transmission medium. For example, the communication interface 1310 enables the communication device 1300 to communicate with other devices. The processor 1320 uses the communication interface 1310 to send and receive data, and is used to implement the method described in the above method embodiments.

[0208] The communication device 1300 may further include at least one memory 1330 for storing program instructions and / or data. The memory 1330 is coupled to the processor 1320.

[0209] When the communication device 1300 is powered on, the processor 1320 can read the software program in the memory 1330, interpret and execute the instructions of the software program, and process the data of the software program. In response to the need to transmit data wirelessly, the processor 1320 performs baseband processing on the data to be transmitted and outputs a baseband signal to the radio frequency (RF) circuit (not shown in Figure 5). The RF circuit processes the baseband signal and transmits the RF signal outwards in the form of electromagnetic waves through the antenna. In response to data being sent to the communication device 1300, the RF circuit receives the RF signal through the antenna, converts the RF signal into a baseband signal, and outputs the baseband signal to the processor 1320. The processor 1320 converts the baseband signal back into data and processes the data.

The connection methods between other components are only illustrative and are not intended to be limiting. The bus can be divided into address bus, data bus, control bus, etc. For ease of illustration, only one thick line is used in Figure 5, but this does not mean that there is only one bus or one type of bus.

[0212] When the communication device 1300 is used as a network device, such as a chip or chip system, the communication interface 1310 may output or receive baseband signals. When the communication device 1300 is a terminal device, the communication interface 1310 may output or receive radio frequency signals.
