Description

Technical Field

[0001] This disclosure relates to wireless communication technology, and more particularly to methods for node execution in a wireless communication system and the various nodes themselves. Background Technology

[0002] Given the successive generations of wireless communication development, these technologies have primarily been developed for human-oriented services such as voice calls, multimedia services, and data services. With the commercialization of 5th-generation (5G) communication systems, the number of connected devices is expected to grow exponentially. These will increasingly connect to communication networks. Examples of the Internet of Things (IoT) can include vehicles, robots, drones, home appliances, displays, smart sensors connected to various infrastructures, construction machinery, and factory equipment. Mobile devices are expected to evolve in various forms, such as augmented reality glasses, virtual reality headsets, and holographic devices. Efforts are underway to develop improved 6G communication systems to provide a wide range of services by connecting hundreds of billions of devices and things in the sixth-generation (6G) era. For these reasons, 6G communication systems are referred to as "beyond 5G" systems.

[0003] The 6G communication system, which is expected to be commercialized around 2030, will have peak data rates in the megabit (1,000 gigabits) bps range and radio latency of less than 100 μsec. Therefore, it will be 50 times the data rate of the 5G communication system and have 1 / 10 of its radio latency.

[0004] To achieve such high data rates and ultra-low latency, 6G communication systems have been considered for implementation in the terahertz band (e.g., the 95 GHz to 3 THz band). It is anticipated that, due to more severe path loss and atmospheric absorption in the terahertz band compared to the millimeter wave (mmWave) band introduced in 5G, technologies capable of ensuring signal transmission distance (i.e., coverage) will become even more critical. As a key technology for ensuring coverage, it is necessary to develop radio frequency (RF) components, antennas, and novel waveforms with better coverage than orthogonal frequency division multiplexing (OFDM), beamforming, massive MIMO (multiple input multiple output), full dimensional multiple input multiple output (FD-MIMO), array antennas, and multi-antenna transmission technologies such as massive MIMO. In addition, new technologies for improving terahertz band signal coverage have been discussed, such as metamaterial-based lenses and antennas, orbital angular momentum (OAM), and reconfigurable intelligence surfaces (RIS).

[0005] In addition, to improve spectrum efficiency and overall network performance, the following technologies have been developed for 6G communication systems: full-duplex technology to enable uplink and downlink transmissions to use the same frequency resources simultaneously; network technologies that utilize satellites, high-altitude platform stations (HAPS), etc., in a comprehensive manner; improved network architecture to support mobile base stations, etc., and to enable network operation optimization and automation; dynamic spectrum sharing technology based on spectrum usage prediction and conflict avoidance; the use of artificial intelligence (AI) in wireless communication to improve overall network operation by utilizing AI from the design phase of 6G development and internalizing end-to-end AI support functions; and next-generation distributed computing technologies that overcome the computing power limitations of user equipment (UE) by leveraging ultra-high-performance communication and computing resources (such as mobile edge computing (MEC), cloud, etc.) achievable on the network. Furthermore, efforts are continuing to enhance connectivity between devices, optimize networks, promote the software-defined networking of network entities, and increase the openness of wireless communications by designing new protocols to be used in 6G communication systems, developing mechanisms for achieving hardware-based secure environments and secure data use, and developing technologies for maintaining privacy.

[0006] The research and development of 6G communication systems, encompassing hyper-connectivity for both person-to-machine (P2M) and machine-to-machine (M2M) interactions, is expected to deliver the next wave of hyper-connected experiences. Specifically, services such as truly immersive extended reality (XR), high-fidelity mobile holograms, and digital replicas are anticipated to be provided through 6G communication systems. Furthermore, services such as remote surgery for enhanced security and reliability, industrial automation, and emergency response will be available via 6G communication systems, enabling the technology to be applied across a wide range of sectors including industry, healthcare, automotive, and home appliances.

[0007] To configure user equipment (UE), base stations need to send various configuration information to the UE. However, the continuous evolution of wireless communication systems has led to increasingly complex UE configuration information, significantly increasing system signaling overhead. Therefore, reducing signaling overhead has become a pressing issue in 6G system design. Summary of the Invention

[0086] The accompanying drawings and various embodiments used to describe the principles of this disclosure are for illustrative purposes only and should not be construed as limiting the scope of this disclosure in any way. Those skilled in the art will understand that the principles of this disclosure can be implemented in any suitably arranged system or apparatus.

[0087] Figure 1 An example wireless network according to an embodiment of this disclosure is shown. Figure 1 The embodiments of the wireless network shown are for illustrative purposes only. Other embodiments of the wireless network 100 may be used without departing from the scope of this disclosure.

[0088] like Figure 1As shown, the wireless network includes a base station (next generation nodeB, gNB or gNodeB) 101, gNB 102, and gNB 103. gNB 101 communicates with gNB 102 and gNB 103. gNB 101 also communicates with at least one network 130 such as the Internet, Internet Protocol (IP) networks, or other data networks.

[0089] gNB 102 provides wireless broadband access to network 130 to multiple first user equipments (UEs) within coverage area 120 of gNB 102. The multiple first UEs include UE 111, which may be located in a small business (SB); UE 112, which may be located in an enterprise (E); UE 113, which may be located in a WiFi hotspot (HS); UE 114, which may be located in a first residence (R1); UE 115, which may be located in a second residence (R2); and UE 116, which may be a mobile device (M) such as a cellular phone, wireless laptop, or wireless personal digital assistant (PDA). gNB 103 provides wireless broadband access to network 130 to multiple second UEs within coverage area 125 of gNB 103. The multiple second UEs include UE 115 and UE 116, and subscriber stations (SS, such as UEs) 117, 118, and 119. In some embodiments, one or more of gNBs 101 and 103 may communicate with each other and UEs 111 and 116 using existing wireless communication technologies, and one or more of UEs 111 and 119 may communicate directly with each other (e.g., UEs 117 and 119) using other existing or proposed wireless communication technologies.

[0090] Depending on the network type, the term "base station" or "BS" can refer to any component (or set of components) configured to provide wireless access to a network, such as a transmit point (TP), transmit-receive point (TRP), enhanced (or "evolved") base station (eNodeB or eNB), 5G base station (gNB), macro cell, femtocell, wireless fidelity (WiFi) access point (AP), or other wireless-capable devices. A base station can provide wireless access according to one or more wireless communication protocols, such as 3GPP 5G new radio (NR), Long Term Evolution (LTE), LTE-Advanced (LTE A), high-speed packet access (HSPA), WiFi 802.11a / b / g / n / ac, etc. For convenience, various names for base station type devices and functions may be used interchangeably in this patent document to refer to network infrastructure components that provide wireless access to remote terminals. Furthermore, depending on the network type, the term "User Equipment" (UE) can refer to any component such as a mobile station (MS), user station (SS), remote terminal, wireless terminal, receiving point, or user device. For convenience, various names for user equipment type devices and functions may be used interchangeably in this patent document to refer to remote wireless devices that wirelessly access the BS regardless of whether the UE is a mobile device (such as a mobile phone or smartphone) or is generally considered a fixed device (such as a desktop computer or vending machine).

[0091] The dashed lines indicate the approximate extent of coverage areas 120 and 125, which are shown as roughly circular for illustrative and explanatory purposes only. It should be clearly understood that coverage areas such as 120 and 125 associated with the gNB can have other shapes, including irregular shapes, depending on the configuration of the gNB and variations in the wireless environment associated with natural and man-made obstacles.

[0092] As described in more detail below, one or more of UEs 111 and 119 include circuitry, programming, or a combination thereof. In some embodiments, one or more of gNBs 101 and 103 include circuitry, programming, or a combination thereof.

[0093] although Figure 1 An example of a wireless network is shown, but more can be found on... Figure 1Various modifications can be made. For example, wireless network 100 can include any number of gNBs and any number of UEs in any suitable arrangement. Furthermore, gNB 101 can communicate directly with any number of UEs and provide those UEs with wireless broadband access to network 130. Similarly, each gNB 102 or 103 can communicate directly with network 130 and provide UEs with direct wireless broadband access to network 130. Additionally, gNBs 101, 102, and / or 103 can provide access to other or additional external networks, such as external telephone networks or other types of data networks.

[0094] Figure 2 An example base station according to an embodiment of the present disclosure is shown. Figure 2 The embodiment of gNB 102 shown is for illustrative purposes only, and Figure 1 gNBs 101 and 103 can have the same or similar configurations. However, gNBs come in a variety of configurations, and Figure 2 This disclosure is not intended to limit the scope to any particular implementation of gNB.

[0095] like Figure 2 As shown, gNB 102 includes multiple antennas 200a 200n, multiple radio frequency (RF) transceivers 201a 201n, transmit (TX) processing circuitry 203, and receive (RX) processing circuitry 204. gNB 102 also includes a controller / processor 205, a memory 206, and a backhaul or network interface 207.

[0096] RF transceivers 201a and 201n receive incoming RF signals, such as signals transmitted by the UE in network 100, from antennas 200a and 200n. RF transceivers 201a and 201n down-convert the incoming RF signals to generate intermediate frequency (IF) or baseband signals. The IF or baseband signal is sent to RX processing circuitry 204, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. RX processing circuitry 204 sends the processed baseband signal to controller / processor 205 for further processing.

[0097] TX processing circuit 203 receives analog or digital data (such as voice data, web data, email, or interactive video game data) from controller / processor 205. TX processing circuit 203 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. RF transceivers 201a and 201n receive the processed baseband or IF signal from TX processing circuit 203 and up-convert the baseband or IF signal into an RF signal transmitted via antennas 201a and 201n.

[0098] The controller / processor 205 may include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 205 may control the reception of forward channel signals and the transmission of reverse channel signals by the RF transceivers 201a 201n, the RX processing circuit 204, and the TX processing circuit 203, according to known principles. The controller / processor 205 may also support additional functions, such as more advanced wireless communication capabilities.

[0099] For example, the controller / processor 205 can support beamforming or directional routing operations, where outgoing signals from multiple antennas 200a 200n are weighted differently to effectively redirect the outgoing signals in the desired direction. Any of a variety of other functions can be supported in the gNB 102 via the controller / processor 205.

[0100] The controller / processor 205 is also capable of executing programs and other processes located in the memory 206, such as the operating system (OS). The controller / processor 205 can move data into or out of the memory 206 as needed by the executing process.

[0101] The controller / processor 205 is also connected to a backhaul or network interface 207. The backhaul or network interface 207 allows the gNB 102 to communicate with other devices or systems via a backhaul connection or over a network. Interface 207 can support communication via any suitable wired or wireless connection(s). For example, when the gNB 102 is implemented as part of a cellular communication system (such as a cellular communication system supporting 5G, LTE, or LTE A), interface 207 can allow the gNB 102 to communicate with other gNBs via a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, interface 207 can allow the gNB 102 to communicate via a wired or wireless local area network or via a wired or wireless connection to a larger network (such as the Internet). Interface 207 includes any suitable structure that supports communication via wired or wireless connections such as Ethernet or RF transceivers.

[0102] Memory 206 is connected to controller / processor 205. A portion of memory 206 may include random access memory (RAM), and another portion of memory 206 may include flash memory or other read-only memory (ROM).

[0103] although Figure 2 An example of gNB 102 is shown, but it is possible to see more. Figure 2 Various changes can be made. For example, gNB 102 can include any number of Figure 2 Each component is shown in the diagram. As a specific example, an access point may include multiple interfaces 207, and the controller / processor 205 may support routing functionality to route data between different network addresses. As another specific example, although shown as a single instance of TX processing circuitry 203 and a single instance of RX processing circuitry 204, gNB102 may include multiple instances of each (such as one per RF transceiver). For example, Figure 2 The various components can be combined, further subdivided, or omitted, and additional components can be added as needed.

[0104] Figure 3 An example user equipment according to an embodiment of the present disclosure is shown. Figure 3 The embodiment of UE 116 shown is for illustrative purposes only, and Figure 1 UEs 111, 115, 117, and 119 can have the same or similar configurations. However, UEs appear in multiple configurations, and Figure 3 This disclosure is not intended to limit the scope to any particular implementation of the UE.

[0105] like Figure 3 As shown, UE 116 includes an antenna 301, a radio frequency (RF) transceiver 302, a TX processing circuit 303, a microphone 304, and a receive (RX) processing circuit 305. UE 116 also includes a speaker 306, a controller or processor 307, an input / output (I / O) interface (IF) 308, an input device 309, a touchscreen display 310, and memory 311. Memory 311 includes an OS 312 and one or more applications 313.

[0106] RF transceiver 302 receives incoming RF signals transmitted by gNB of network 100 from antenna 301. RF transceiver 302 down-converts the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to RX processing circuitry 305, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. RX processing circuitry 305 sends the processed baseband signals to speaker 306 (e.g., for voice data) or processor 307 for further processing (e.g., for web browsing data).

[0107] TX processing circuit 303 receives analog or digital voice data from microphone 304 or other outgoing baseband data (such as web data, email, or interactive video game data) from processor 307. TX processing circuit 303 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. RF transceiver 302 receives the processed baseband or IF signal from TX processing circuit 303 and up-converts the baseband or IF signal into an RF signal transmitted via antenna 301.

[0108] Processor 307 may include one or more processors or other processing devices and executes OS 312 stored in memory 311 to control the overall operation of UE 116. For example, processor 307 may control the reception of forward channel signals and the transmission of reverse channel signals by RF transceiver 302, RX processing circuitry 305, and TX processing circuitry 303 according to known principles. In some embodiments, processor 307 includes at least one microprocessor or microcontroller.

[0109] Processor 307 is also capable of executing other processes and programs located in memory 311, such as processes for CSI reporting on the uplink channel. Processor 307 can move data into or out of memory 311 as needed for executing processes. In some embodiments, processor 307 is configured to execute application 313 based on OS 312 or in response to signals received from gNB or operator. Processor 307 is also coupled to I / O interface 308, which provides UE 116 with the ability to connect to other devices such as laptops and laptops. I / O interface 308 is the communication path between these accessories and processor 307.

[0126] ■WIFI access point.

[0127] In a wireless network, to ensure normal communication between two nodes, the two nodes need to obtain communication-related configuration information. This configuration information may be sent by one node to the other, or it may be sent separately by other nodes to both nodes. After receiving the configuration information, each node configures its own communication module and communicates with the other node according to the configuration information (e.g., the first node communicates with the second node). In one example, the two nodes may be a base station and a user equipment (UE), in which case the configuration information may be sent from the base station to the UE, or from the UE to the base station. In another example, the two nodes may be a first UE and a second UE, in which case the configuration information may be sent from the first UE to the second UE, or from the second UE to the first UE. In yet another example, the two nodes may be a first UE and a second UE, and the other node is a base station, in which case the configuration information is sent separately by the base station to both the first and second UEs. This configuration information may include at least one of the following configurations:

[0128] ■ Data configuration information, which contains configuration information for the transmitted data. This information may include configuration information for one or more types of data. The data may be at least one of the following types (the data types here are just examples and other types of data are not excluded): radio bearer (RB), data radio bearer (DRB), signaling radio bearer (SRB), radio link control bearer (RLC), session data, packet data unit session (PDUSession) data, flow data, quality of service flow (QoS flow) data, and Internet Protocol (IP) data.

[0130] ■ Channel configuration information. This information includes the configuration information of different channels for serving data transmission. This information may include the configuration information of one or more channels. The channel may be at least one of the following channels (the channel types here are just examples and other types of channels are not excluded): logical channel, downlink control channel (e.g., PDCCH: Physical Downlink Control Channel), downlink shared channel (e.g., PDSCH: Physical Downlink Shared Channel), uplink control channel (e.g., PUCCH: Physical Uplink Control Channel), uplink shared channel (e.g., PUSCH: Physical Uplink Shared Channel), random access channel (e.g., PRACH: Physical Random Access Channel), broadcast control channel (e.g., MCCH: Multicast / Broadcast Services Control Channel), and broadcast data stream channel (e.g., MTCH: Multicast / Broadcast Services Traffic Channel). Channel), sidelink control channel (e.g., PSCCH: Physical Sidelink Control Channel), sidelink shared channel (e.g., PSSCH: Physical Sidelink Shared Channel), sidelink feedback channel (e.g., PSFCH: Physical Sidelink Feedback Channel), backhaul link channel (e.g., backhaul RLC channel: backhaul radio link control channel), sidelink channel (e.g., sidelinkRLC channel: sidelink RLC channel), radio link control channel (e.g., RLC CH: RLC channel).

[0131] ■ Measurement configuration information, which contains the configuration information required for the node to perform measurements.

[0132] The aforementioned configuration information may include configuration information for different types of data / cells / channels / measurements, leading to significant signaling overhead. To reduce this signaling overhead, this invention provides a configuration method based on a reference configuration (or configuration template). In this method, such as... Figure 4 As shown, the configuration information required by nodes in a wireless network is generated based on a reference configuration and a delta configuration. The reference configuration may be a data reference configuration, a cell reference configuration, a channel reference configuration, a measurement reference configuration, etc., while the delta configuration may contain one or more delta configurations, each containing configuration information that differs from the corresponding reference configuration. For example... Figure 4 As shown, the reference configuration is used to generate configurations 1, 2, and 3 using differential configurations 1, 2, and 3 respectively. This way, when configuring a node, only one reference configuration and multiple differential configurations need to be sent, instead of sending configurations 1, 2, and 3 to the node. Since differential configurations 1, 2, and 3 only contain information that differs from the reference configuration, their size is smaller than configurations 1, 2, and 3, thus reducing the signaling overhead for the configuration node. In one example, a node in a wireless network receives a reference configuration for data, as well as two differential configurations for two different bearers (such as differential configurations for bearer 1 and bearer 2). The node can then generate the complete configuration for bearer 1 based on the reference configuration and the differential configuration for bearer 1, and generate the complete configuration for bearer 2 based on the reference configuration and the differential configuration for bearer 2.

[0133] In this invention, "bearer" can refer to at least one of the following types of data: radio bearer (RB), data radio bearer (DRB), signaling radio bearer (SRB), radio link control bearer (RLC), session data, packet data unit session (PDU) data, flow data, quality of service flow (QoS) flow data, and Internet Protocol (IP) data. Therefore, in the following description, "bearer" can be replaced by at least one of "radio bearer," "data radio bearer," "signaling radio bearer," "RLC bearer," "PDU session," "flow," "QoS flow," and "IP."

[0223] This invention includes the following process, such as Figure 5 As shown:

In one example, this information contains complete / full configuration information for the second node; in another example, it contains configuration information that differs from the aforementioned "first configuration information." Upon receiving this information, the second node needs to combine it with the aforementioned first configuration information to generate its complete configuration information.

[0229] ◆ Wireless bearer configuration information

[0230] ◆RLC bearer configuration information

[0231] ◆Configuration Information

[0232] ◆Community Configuration Information

[0233] ◆RLC channel configuration information

[0234] ◆Channel Configuration Information

[0235] ◆ Measurement Configuration Information

[0236] ■ Reference configuration indication information, which indicates that a set of configuration information (or the aforementioned "third configuration information") identified by the "configuration identification information" is reference configuration information, and other sets of configuration information can be generated based on this reference configuration information. Furthermore, this indication information may also include identification information of the reference configuration, or the indication information itself may be identification information of the reference configuration.

[0237] ■ The associated configuration indication information indicates the identification information of the associated reference configuration. In one example, when one of the multiple sets of configuration information contained in the above-mentioned "Second Configuration Information" is used as the reference configuration, this information is the "Configuration Identification Information" corresponding to that set of configuration information; in another example, when the above-mentioned "First Configuration Information" is used as the reference configuration, this information is the identification information contained in the above-mentioned "First Configuration Information" (such as "Reference Configuration Identification Information", "Radio Bearer Reference Configuration Identification Information", "RLC Bearer Reference Configuration Identification Information", "Bearer Reference Configuration Identification Information", "Cell Reference Configuration Identification Information", "RLC Channel Reference Configuration Identification Information", "Channel Reference Configuration Identification Information", "Channel Reference Configuration Identification Information", "Measurement Reference Configuration Identification Information", "Measurement Target Reference Configuration Identification Information", "Measurement Reporting Reference Configuration Identification Information", etc.). After receiving this information, the second node will use the set of configuration information identified by the identification information as the reference configuration information.

[0238] ■ Differential configuration information, which includes a set of configuration information that differs from the reference configuration information identified by the aforementioned "configuration identification information". The second node combines this information with the reference configuration information to obtain the configuration information required by the second node. This information includes at least one of the following:

[0239] ◆ Wireless bearer configuration information

[0240] ◆RLC bearer configuration information

[0241] ◆Configuration Information

[0242] ◆Community Configuration Information

[0243] ◆RLC channel configuration information

[0244] ◆Channel Configuration Information

[0245] ◆ Measurement Configuration Information

[0246] Step 1-2: The second node obtains reference configuration information based on the information in the first configuration message, and / or generates configuration information for the second node, wherein the configuration information for the second node includes at least one of the following:

[0247] ◆ Wireless bearer configuration information

[0248] ◆RLC bearer configuration information

[0249] ◆Configuration Information

[0250] ◆Community Configuration Information

[0251] ◆RLC channel configuration information

[0252] ◆Channel Configuration Information

[0253] ◆ Measurement Configuration Information

[0254] In this step, the second node includes the following behaviors:

[0255] ■ Obtain reference configuration information

[0256] When the aforementioned "first configuration message" contains the aforementioned "first configuration information," the second node uses the "first configuration information" as reference configuration information; when the aforementioned first configuration message contains "reference configuration indication information," the second node uses the "third configuration information" corresponding to the "reference configuration indication information" as reference configuration information.

[0257] ■ The required configuration information is generated, which can be implemented in two ways:

[0258] ■ Implementation Method 1: Generate configuration information based on "first configuration information"

[0259] In this embodiment, the second node provides reference configuration information through the aforementioned "first configuration information". When the second node receives the aforementioned first configuration message, for any set of configuration information contained in the "second configuration information", if the configuration information contains "identification information of associated configuration", the second node uses the configuration information identified by the "identification information of associated configuration" in the aforementioned "first configuration information" as reference configuration information, and then combines it with "differential configuration information" to generate the configuration information required by the second node. If the configuration information does not contain "identification information of associated configuration", the second node uses the aforementioned "first configuration information" as reference configuration information, and then combines it with "differential configuration information" to generate the configuration information of the second node.

[0260] ■Implementation Method 2: Generate configuration information based on the "third configuration information" corresponding to the "reference configuration instruction information".

[0261] In this embodiment, the second node uses a set of configuration information from the aforementioned "second configuration information" as reference configuration information. This set of configuration information includes the aforementioned "reference configuration indication information." In one example, the reference configuration information is the "third configuration information" corresponding to the "reference configuration indication information" in the aforementioned "second configuration information." Further, for the other sets of configuration information included in the aforementioned "second configuration information" (excluding the set of configuration information that includes the aforementioned "reference configuration indication information"), the second node generates its own configuration information based on the aforementioned reference configuration information and the "difference configuration information."

[0262] In the above steps, one possible implementation is that the "first configuration information" and "second configuration information" are sent through the same message, and the second node can generate its own configuration information after receiving the message; another possible implementation is that the "first configuration information" is sent to the second node through one message, and then the "second configuration information" is sent to the second node through another message; yet another possible implementation is that the first configuration message only contains the "second configuration information", and one set of configuration information in the "second configuration information" can be used as a reference configuration, with other sets of configuration information generated based on this reference configuration.

[0263] The aforementioned first configuration message can be a Radio Resource Control (RRC) message, such as an RRC Reconfiguration message, an RRC Setup message, an RRC Restart message, an RRC Reconfiguration sidelink message, or other types of messages.

[0264] The beneficial effect of the above process is that by configuring reference configuration and differential configuration, the signaling overhead of sending configuration information is reduced, and the efficiency of radio resource utilization is improved.

[0265] The present invention includes the following possible embodiments based on specific configuration information. In the following embodiments, if the first node provides only reference configuration information, it may not need to send "associated configuration identification information" to the second node. The second node can then generate its own configuration information based on the reference configuration information and one or more received differential configuration information. In the following embodiments, the second node may receive at least one differential configuration information. The second node combines this differential configuration information with the corresponding reference configuration to generate at least one second node's configuration information. The second node's configuration information may be at least one of the following (in one example, when the second node's configuration information is a combination of multiple of the following, the configuration information of a second node may be the configuration information of a cell group):

[0266] ● Wireless bearer configuration information

[0267] ●RLC bearer configuration information

[0268] ●Configuration information

[0269] ●Community Configuration Information

[0270] ●RLC channel configuration information

[0271] ●Channel Configuration Information

[0284] In one example, the above reference configuration information can be the configuration information of a cell group (such as Cell GroupConfig).

[0285] ■ When the reference configuration is sent via the aforementioned "first configuration information"

[0286] The second node can receive the "first configuration information" via a first message, which is specifically used to send reference configuration information. This first message may contain one or more reference configuration information entries, each identified by a corresponding "reference configuration identifier." In one example, the first message also includes the aforementioned "second configuration information." In another example, the aforementioned "second configuration information" may be sent to the second node via a second message. The "second configuration information" may contain one or more sets of configuration information (in one example, this set of configuration information may be the configuration information of a cell group). Each set of configuration information contains at least one of the following: "configuration identifier information," "associated configuration identifier information" (this information is the identifier of one of the reference configuration information entries in the aforementioned "first configuration information," which the second node uses to determine the reference configuration information), and "difference configuration information." The second node generates its required set of configuration information (such as the configuration information of a cell group) based on the "difference configuration information" and the corresponding reference configuration information. In one implementation, the second node is for generating configuration information for multiple cell groups. The aforementioned "first configuration information" includes one or more cell group reference configuration information, and each set of configuration information included in the aforementioned "second configuration information" corresponds to a cell group configured for the second node. The second node will generate a complete configuration for a cell group configured for the second node based on the cell group reference configuration information in the "first configuration information" and a "differential configuration information" in the "second configuration information".

If one set of configuration information contains "reference configuration indication information," then this set of configuration information (containing at least one of "configuration identification information" and "third configuration information") can be used as reference configuration information. If one set of configuration information contains "associated configuration identification information" (this set of configuration information also contains at least one of "configuration identification information" and "difference configuration information"), then the second node can determine the associated reference configuration information based on this information, and generate a set of configuration information required by the second node based on the reference configuration information and the "difference configuration information" contained in the set of configuration information. In one embodiment, the second node is generating configuration information for multiple cell groups. The aforementioned "second configuration information" contains cell group configuration information configured for one or more cell groups of the second node. In one example, the "configuration identification information" in each cell group configuration information may be the cell group identification information. The cell group configuration information that can be used as a reference configuration includes the aforementioned "reference configuration indication information", while the cell group configuration information that cannot be used as a reference configuration includes "identification information of associated configuration" (this information includes the identifier of the cell group configuration information corresponding to the reference configuration; in one example, this information is the cell group identification information) and "differential configuration information". Therefore, the second node can combine the reference configuration and the different configuration information to generate a complete configuration of a cell group.
