Description

METHOD PERFORMED BY A NODE IN A WIRELESS COMMUNICATION SYSTEM AND NODE

[0001] The present disclosure relates to wireless communication technology, and in particular to methods performed by nodes in a wireless communication system and respective nodes.

[0002] Considering the development of wireless communication from generation to generation, the technologies have been developed mainly for services targeting humans, such as voice calls, multimedia services, and data services. Following the commercialization of 5G (5th generation) communication systems, it is expected that the number of connected devices will exponentially grow. Increasingly, these will be connected to communication networks. Examples of connected things may include vehicles, robots, drones, home appliances, displays, smart sensors connected to various infrastructures, construction machines, and factory equipment. Mobile devices are expected to evolve in various form-factors, such as augmented reality glasses, virtual reality headsets, and hologram devices. In order to provide various services by connecting hundreds of billions of devices and things in the 6G (6th generation) era, there have been ongoing efforts to develop improved 6G communication systems. For these reasons, 6G communication systems are referred to as beyond-5G systems.

[0003] 6G communication systems, which are expected to be commercialized around 2030, will have a peak data rate of tera (1,000 giga)-level bit per second (bps) and a radio latency less than 100μsec, and thus will be 50 times as fast as 5G communication systems and have the 1 / 10 radio latency thereof.

[0004] In order to accomplish such a high data rate and an ultra-low latency, it has been considered to implement 6G communication systems in a terahertz (THz) band (for example, 95 gigahertz (GHz) to 3THz bands). It is expected that, due to severer path loss and atmospheric absorption in the terahertz bands than those in mmWave bands introduced in 5G, technologies capable of securing the signal transmission distance (that is, coverage) will become more crucial. It is necessary to develop, as major technologies for securing the coverage, Radio Frequency (RF) elements, antennas, novel waveforms having a better coverage than Orthogonal Frequency Division Multiplexing (OFDM), beamforming and massive Multiple-input Multiple-Output (MIMO), Full Dimensional MIMO (FD-MIMO), array antennas, and multiantenna transmission technologies such as large-scale antennas. In addition, there has been ongoing discussion on new technologies for improving the coverage of terahertz-band signals, such as metamaterial-based lenses and antennas, Orbital Angular Momentum (OAM), and Reconfigurable Intelligent Surface (RIS).

[0005] Moreover, in order to improve the spectral efficiency and the overall network performances, the following technologies have been developed for 6G communication systems: a full-duplex technology for enabling an uplink transmission and a downlink transmission to simultaneously use the same frequency resource at the same time; a network technology for utilizing satellites, High-Altitude Platform Stations (HAPS), and the like in an integrated manner; an improved network structure for supporting mobile base stations and the like and enabling network operation optimization and automation and the like; a dynamic spectrum sharing technology via collision avoidance based on a prediction of spectrum usage; an use of Artificial Intelligence (AI) in wireless communication for improvement of overall network operation by utilizing AI from a designing phase for developing 6G and internalizing end-to-end AI support functions; and a next-generation distributed computing technology for overcoming the limit of UE computing ability through reachable super-high-performance communication and computing resources (such as Mobile Edge Computing (MEC), clouds, and the like) over the network. In addition, through designing new protocols to be used in 6G communication systems, developing mechanisms for implementing a hardware-based security environment and safe use of data, and developing technologies for maintaining privacy, attempts to strengthen the connectivity between devices, optimize the network, promote softwarization of network entities, and increase the openness of wireless communications are continuing.

[0006] It is expected that research and development of 6G communication systems in hyper-connectivity, including person to machine (P2M) as well as machine to machine (M2M), will allow the next hyper-connected experience. Particularly, it is expected that services such as truly immersive eXtended Reality (XR), high-fidelity mobile hologram, and digital replica could be provided through 6G communication systems. In addition, services such as remote surgery for security and reliability enhancement, industrial automation, and emergency response will be provided through the 6G communication system such that the technologies could be applied in various fields such as industry, medical care, automobiles, and home appliances.

[0085] Hereinafter, embodiments of the disclosure will be described in detail with reference to the accompanying drawings.

[0086] In describing the embodiments, descriptions related to technical contents well-known in the art and not associated directly with the disclosure will be omitted. Such an omission of unnecessary descriptions is intended to prevent obscuring of the main idea of the disclosure and more clearly transfer the main idea.

[0087] For the same reason, in the accompanying drawings, some elements may be exaggerated, omitted, or schematically illustrated. Further, the size of each element does not completely reflect the actual size. In the drawings, identical or corresponding elements are provided with identical reference numerals or different reference numerals.

[0088] The advantages and features of the disclosure and ways to achieve them will be apparent by making reference to embodiments as described below in detail in conjunction with the accompanying drawings. However, the disclosure is not limited to the embodiments set forth below, but may be implemented in various different forms. The following embodiments are provided only to completely disclose the disclosure and inform those skilled in the art of the scope of the disclosure, and the disclosure is defined only by the scope of the appended claims. Throughout the specification, the same or like reference numerals designate the same or like elements. Furthermore, in describing the disclosure, a detailed description of known functions or constitution incorporated herein will be omitted in the case that it is determined that the description may make the subject matter of the disclosure unnecessarily unclear. The terms which will be described below are terms defined in consideration of the functions in the disclosure, and may be different according to users, intentions of the operators, or customs. Therefore, the definitions of the terms should be made based on the contents throughout the specification.

[0089] Herein, it will be understood that each block of the flowchart illustrations, and combinations of blocks in the flowchart illustrations, may be performed based on computer program instructions. These computer program instructions may be loaded collectively onto at least one processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which perform through any one of, or in any combination of, the at least one processor of the computer or other programmable data processing apparatus, create means for performing the functions specified in the flowchart block(s). These computer program instructions may also be stored in a non-transitory computer usable or computer-readable memory that may direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer usable or computer-readable memory produce an article of manufacture including instruction means that perform the function specified in the flowchart block(s). The computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable data processing apparatus to produce a computer executed process such that the instructions that perform on the computer or other programmable data processing apparatus provide steps for executing the functions specified in the flowchart block(s).

[0090] Further, each block may represent a module, segment, or portion of code, which includes one or more executable instructions for executing the specified logical function(s). It should also be noted that in some alternative implementations, the functions noted in the blocks may occur out of the order. For example, two blocks(or functions) shown in succession may in fact be performed substantially concurrently or the blocks may sometimes be performed in the reverse order, depending upon the functionality involved.

[0091] As used in embodiments of the disclosure, a "~unit" may refer to a software element or a hardware element, such as a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC), which performs a predetermined function. However, the term including the word "~unit" does not always have a meaning limited to software or hardware. The "~unit" may be constructed either to be stored in an addressable storage medium or to execute one or more processors. Therefore, the "~unit" includes, for example, software elements, object-oriented software elements, components such as class elements and task elements, processes, functions, properties, procedures, sub-routines, segments of a program code, drivers, firmware, micro-codes, circuits, data, database, data structures, tables, arrays, and parameters. The components and functions provided by the "~unit" may be either combined into a smaller number of components and a "~unit," or divided into additional components and a "~unit." Moreover, the components and "~units" may be implemented to reproduce one or more central processing units (CPUs) within a device or a security multimedia card. Further, in the embodiments, the "~unit" may include one or more processors.

[0092] It should be appreciated that the blocks in each flowchart and combinations of the flowcharts may be performed by one or more computer programs which include instructions. The entirety of the one or more computer programs may be stored in a single memory device or the one or more computer programs may be divided with different portions stored in different multiple memory devices.

[0093] Any of the functions or operations described herein can be processed by one processor or a combination of processors. The one processor or the combination of processors is circuitry performing processing and includes circuitry like an application processor (AP, e.g. a CPU), a communication processor (CP, e.g., a modem), a graphics processing unit (GPU), a neural processing unit (NPU) (e.g., an artificial intelligence (AI) chip), a Wi-Fi chip, a Bluetooth® chip, a global positioning system (GPS) chip, a near field communication (NFC) chip, connectivity chips, a sensor controller, a touch controller, a finger-print sensor controller, a display driver integrated circuit (IC), an audio CODEC chip, a universal serial bus (USB) controller, a camera controller, an image processing IC, a microprocessor unit (MPU), a system on chip (SoC), an IC, or the like.

[0094] It will be appreciated that various embodiments of the disclosure according to the claims and description in the specification can be realized in the form of hardware, software or a combination of hardware and software.

[0095] Any such software may be stored in non-transitory computer readable storage media. The non-transitory computer readable storage media store one or more computer programs (software modules), the one or more computer programs include computer-executable instructions that, when executed by one or more processors of an electronic device individually or collectively, cause the electronic device to perform a method of the disclosure.

[0096] Any such software may be stored in the form of volatile or non-volatile storage such as, for example, a storage device like read only memory (ROM), whether erasable or rewritable or not, or in the form of memory such as, for example, random access memory (RAM), memory chips, device or integrated circuits or on an optically or magnetically readable medium such as, for example, a compact disk (CD), digital versatile disc (DVD), magnetic disk or magnetic tape or the like. It will be appreciated that the storage devices and storage media are various embodiments of non-transitory machine-readable storage that are suitable for storing a computer program or computer programs comprising instructions that, when executed, implement various embodiments of the disclosure. Accordingly, various embodiments of the present disclosure may provide a program comprising code for implementing apparatus or a method as claimed in any one of the claims of this specification and a non-transitory machine-readable storage storing such a program.

[0097] Hereinafter, the determination of priority between A and B in the present disclosure may refer to various actions such as selecting the one having a higher priority based on a predefined priority rule and performing an operation corresponding thereto, or omitting or dropping an operation corresponding to the one having a lower priority.

[0098] Hereinafter, "A or B" as described in the present disclosure may be understood as "A and / or B," which may include A, or B, or both A and B.

[0099] In addition, "at least one of A, B, and C" as described in the present disclosure may be understood to include A, or B, or C, or any combination of A, B, and C.

[0100] In addition, "at least one of A, B, or C" as described in the present disclosure may be understood to include A, or B, or C, or any combination of A, B, and C.

[0101] Furthermore, "A / B" as described in the present disclosure may be understood as "A and / or B," which may include A, or B, or both A and B.

[0102] Furthermore, "A, B" as described in the present disclosure may be understood as "A and / or B," which may include A, or B, or both A and B.

[0103] Furthermore, "A and B" as described in the present disclosure may be understood as "A and / or B," which may include A, or B, or both A and B.

[0104] Furthermore, "if condition A and condition B are satisfied," as described in the present disclosure, may not be limited to a case where both condition A and condition B are satisfied, but may be understood to include a case where either condition A or condition B is individually satisfied, both condition A and condition B are satisfied, or one or more additional conditions are satisfied in combination.

[0105] Furthermore, throughout this disclosure, ordinal terms such as "first," "second," "third," etc., (and similar qualifiers) are used merely to distinguish between different instances, occurrences, configurations, messages, stages, or aspects of elements, operations, or information as described herein. Unless the context clearly dictates otherwise, the use of such ordinal terms does not itself require that the elements, operations, or information distinguished by these terms be structurally different, numerically distinct, or substantively dissimilar. For example, a "first signal" and a "second signal" may refer to instances of the same signal transmitted at different times or containing the same core information despite minor variations, or they may refer to signals with different content or characteristics, depending on the specific context. Similarly, a "first value" and a "second value" may represent the same magnitude but measured or applied in different circumstances, or they may represent different magnitudes. The interpretation should be guided by the specific technical context, function, and relationship described in the relevant portion of the specification and claims.

[0106] Furthermore, the terms "first ~", "second ~", etc., as described in the present disclosure with respect to various elements (e.g., information, objects, operation, sequences, or the like), should not limit those elements. These terms may only be intended to distinguish one element from another, and may not be intended to indicate a specific order. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element.

[0107] Furthermore, even if "first ~" and "second ~" are described in the present disclosure, it may be understood that element(s) referred to by "first ~" and "second ~" may be the same or different. For example, in case of element(s) being information, first information and second information may both be same information and, in some cases, are separate and different information.

[0108] In addition, the terms "if ~" and "in case that ~" as used in the disclosure or claims may be interpreted to include the meanings of "when (or upon) ~," "in response to ~," "based on ~," or "according to ~," and may be used interchangeably with these expressions. In addition, expressions other than those exemplified herein may also be used, as long as they have substantially the same meaning and do not impair the technical features of the present disclosure.

[0109] For example, the physical layer signaling may be referred to as Layer 1 (L1) signaling and may include downlink control information (DCI). In addition, the higher layer signaling may include a medium access control (MAC) control message, a radio resource control (RRC) signaling message, a non-access stratum (NAS) signaling message, or an application layer message. The RRC signaling message may be referred to as L3 (layer 3) signaling. It should be noted, however, that the higher layer signaling is not limited to the aforementioned examples.

[0110] In addition, the term "not perform" as used in the present disclosure or claims may, in context, be understood to mean that the corresponding step is omitted or skipped. Such a term may be replaced with other terms having the same or substantially equivalent meaning.

[0111] In addition, "transmitting a message including A and B" as described in the present disclosure, may be understood as encompassing both (i) transmitting A and B in a single message, and (ii) transmitting A and B separately via multiple messages (e.g., transmitting a first message including A and a second message including B). This interpretation may also apply to messages that include two or more items (e.g., A, B, C), transmitted either together or separately.

[0112] In addition, "transmitting a message including A and transmitting a message including B" may also be interpreted as transmitting a message including A and B in a single message.

[0113] In the specific embodiments of the present disclosure described below, terms or components included in the disclosure may be expressed in singular or plural form depending on the specific embodiments presented. However, such singular or plural expressions are selected appropriately for convenience of description, and the present disclosure is not limited to a singular or plural number of components. A component expressed in the plural form may be implemented as a single component, and a component expressed in the singular form may be implemented as multiple components.

[0114] The drawings or flowcharts described below illustrate exemplary methods that may be implemented according to the principles of the present disclosure, and various modifications may be made to the methods illustrated in the flowcharts of the present disclosure. For example, although illustrated as a series of steps, various steps in each drawing or flowchart may overlap, occur in parallel, occur in a different order, or be repeated. In other examples, any step may be omitted or replaced with another step.

[0115] The methods and apparatuses proposed in the embodiments of the present disclosure are not limited to each embodiment individually, but may also be applied in combination of all or some of the embodiments proposed in the disclosure. Therefore, the embodiments of the present disclosure may be modified and applied without significantly departing from the scope of the present disclosure, as would be understood by those skilled in the art.

[0116] In this case, even if certain wordings are described differently across embodiments, they may be used interchangeably or in substitution or in combination if their underlying concepts are equivalent. For example, for the same or equivalent concept, even if one embodiment uses the expression "A" and another embodiment uses the expression "B", such expressions may be understood interchangeably, in substitution, or in combination.

[0117] The terms used in the following description to refer to access nodes, network entities, messages, interfaces between network entities, various types of identification information, and the like, are provided merely for the convenience of explanation by way of example. Therefore, the present disclosure is not limited to the terms described below, and other terms having equivalent technical meanings may also be used. Such terms may also be interchangeable with terms defined in any 3rd generation partnership project (3GPP) technical specifications (TS) where appropriate.

[0118] Hereinafter, a base station is an entity that allocates resources to terminals, and may be at least one of a gNode B, an eNode B, a Node B, a base station (BS), a wireless access unit, a BS controller, or a node on a network.

[0119] Furthermore, the base station of the present disclosure may include a split architecture comprising a central unit (CU) and a distributed unit (DU). In this structure, the CU is configured to process the higher layers of the control and user planes, while the DU is configured to process lower-layer radio resource functions. The embodiments of the present disclosure may be equally applicable to 5G base station architectures in which such CU and DU functional splits are implemented.

[0120] A terminal may include a UE, a mobile station (MS), a cellular phone, a smartphone, a computer, or a multimedia system capable of performing communication functions.

[0121] In the disclosure, a downlink (DL) refers to a radio link through which a BS transmits a signal to a UE, and an uplink (UL) refers to a radio link through which a UE transmits a signal to a BS.

[0122] Furthermore, hereinafter, 5th generation (5G) mobile communication technologies (e.g., 5G new radio (NR)), 6th generation (6G) mobile communication technologies may be described by way of example, but the embodiments of the present disclosure may also be applied to other communication systems having similar technical backgrounds or channel types. For example, newly evolved mobile communication systems developed after 5G and 6G may be included. Furthermore, based on determinations by those skilled in the art, the embodiments of the present disclosure may also be applied to other communication systems (e.g., Wi-Fi systems) through some modifications without significantly departing from the scope of the present disclosure

[0123] In the following description, the terms physical channel and signal may be used interchangeably with data or control signal. For example, the term physical downlink shared channel (PDSCH) refers to a physical channel through which data is transmitted, but the term PDSCH may also be used to refer to the data itself. That is, in the present disclosure, the expression "transmit a physical channel" may be interpreted as being equivalent to the expression "transmit data or a signal via a physical channel."

[0124] Hereinafter, in the context of the present disclosure, higher layer signaling may refer to signaling corresponding to at least one or any combination of the following: master information block (MIB), system information block (SIB) or SIB M (M = 1, 2, ...), radio resource control (RRC), or medium access control (MAC) control element (CE), or a non-access stratum (NAS) signaling message, or an application layer message. The RRC signaling message may be referred to as L3 (layer 3) signaling.

[0125] In addition, L1 signaling may refer to signaling corresponding to at least one or any combination of signaling techniques using the at least one or any combination of the following physical layer channels or signaling: physical downlink control channel (PDCCH), downlink control information (DCI), user equipment (UE)-specific DCI, group-common DCI, common DCI, scheduling DCI (e.g., DCI used for scheduling downlink or uplink data), non-scheduling DCI (e.g., DCI not used for scheduling downlink or uplink data) physical uplink control channel (PUCCH), or uplink control information (UCI). The L1 signaling message may be referred to as a physical layer signaling.

[0126] Hereinafter, the expression that information is configured by the BS, as used in the present disclosure or claims, may, in context, be understood to mean that the terminal receives the corresponding information from the BS via a physical layer signaling or a higher layer signaling. Such an expression may be replaced with other terms having the same or substantially equivalent meaning.

[0127] Hereinafter, the operational principle of the present disclosure will be described in detail with reference to the accompanying drawings.

[0128] Considering the development of wireless communication from generation to generation, the technologies have been developed mainly for services targeting humans, such as voice calls, multimedia services, and data services. Following the commercialization of 5th-generation (5G) communication systems, it is expected that the number of connected devices will exponentially grow. Increasingly, these will be connected to communication networks. Examples of connected things may include vehicles, robots, drones, home appliances, displays, smart sensors connected to various infrastructures, construction machines, and factory equipment. Mobile devices are expected to evolve in various form-factors, such as augmented reality glasses, virtual reality headsets, and hologram devices. In order to provide various services by connecting hundreds of billions of devices and things in the 6th-generation (6G) era, there have been ongoing efforts to develop improved 6G communication systems. For these reasons, 6G communication systems are referred to as beyond-5G systems.

[0129] 6G communication systems, which are expected to be commercialized around 2030, will have a peak data rate of tera (1,000 giga)-level bps and a radio latency less than 100μsec, and thus will be 50 times as fast as 5G communication systems and have the 1 / 10 radio latency thereof.

[0130] In order to accomplish such a high data rate and an ultra-low latency, it has been considered to implement 6G communication systems in a terahertz band (for example, 95GHz to 3THz bands). It is expected that, due to severer path loss and atmospheric absorption in the terahertz bands than those in mmWave bands introduced in 5G, technologies capable of securing the signal transmission distance (that is, coverage) will become more crucial. It is necessary to develop, as major technologies for securing the coverage, radio frequency (RF) elements, antennas, novel waveforms having a better coverage than orthogonal frequency division multiplexing (OFDM), beamforming and massive multiple input multiple output (MIMO), full dimensional MIMO (FD-MIMO), array antennas, and multiantenna transmission technologies such as large-scale antennas. In addition, there has been ongoing discussion on new technologies for improving the coverage of terahertz-band signals, such as metamaterial-based lenses and antennas, orbital angular momentum (OAM), and reconfigurable intelligent surface (RIS).

[0131] Moreover, in order to improve the spectral efficiency and the overall network performances, the following technologies have been developed for 6G communication systems: a full-duplex technology for enabling an uplink transmission and a downlink transmission to simultaneously use the same frequency resource at the same time; a network technology for utilizing satellites, high-altitude platform stations (HAPS), and the like in an integrated manner; an improved network structure for supporting mobile base stations and the like and enabling network operation optimization and automation and the like; a dynamic spectrum sharing technology via collision avoidance based on a prediction of spectrum usage; an use of artificial intelligence (AI) in wireless communication for improvement of overall network operation by utilizing AI from a designing phase for developing 6G and internalizing end-to-end AI support functions; and a next-generation distributed computing technology for overcoming the limit of user equipment (UE) computing ability through reachable super-high-performance communication and computing resources (such as mobile edge computing (MEC), clouds, and the like) over the network. In addition, through designing new protocols to be used in 6G communication systems, developing mechanisms for implementing a hardware-based security environment and safe use of data, and developing technologies for maintaining privacy, attempts to strengthen the connectivity between devices, optimize the network, promote softwarization of network entities, and increase the openness of wireless communications are continuing.

[0132] It is expected that research and development of 6G communication systems in hyper-connectivity, including person to machine (P2M) as well as machine to machine (M2M), will allow the next hyper-connected experience. Particularly, it is expected that services such as truly immersive extended reality (XR), high-fidelity mobile hologram, and digital replica could be provided through 6G communication systems. In addition, services such as remote surgery for security and reliability enhancement, industrial automation, and emergency response will be provided through the 6G communication system such that the technologies could be applied in various fields such as industry, medical care, automobiles, and home appliances.

[0133] In order to configure the user equipment, the base station needs to send various configuration information to the user equipment. However, the continuous evolution of wireless communication systems has caused the configuration information of user equipment to become more and more complex, thereby greatly increasing the signaling overhead of the system. Therefore, how to reduce signaling overhead becomes an urgent issue in 6G system design.

[0140] The drawings, discussed below, and the various embodiments used to describe the principles of the present disclosure are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged system or device.

[0141] FIG. 1 illustrates an example wireless network according to embodiments of the present disclosure. The embodiment of the wireless network shown in FIG. 1 is for illustration only. Other embodiments of the wireless network 100 could be used without departing from the scope of the present disclosure.

[0142] As shown in FIG. 1, the wireless network includes a base station (next generation nodeB, gNB or gNodeB) 101, a gNB 102, and a gNB 103. The gNB 101 communicates with the gNB 102 and the gNB 103. The gNB 101 also communicates with at least one network 130, such as the Internet, a proprietary Internet Protocol (IP) network, or other data network.

[0143] The gNB 102 provides wireless broadband access to the network 130 for a first plurality of user equipments (UEs) within a coverage area 120 of the gNB 102. The first plurality of UEs includes a UE 111, which may be located in a small business; a UE 112, which may be located in an enterprise (E); a UE 113, which may be located in a WiFi hotspot (HS); a UE 114, which may be located in a first residence (R1); a UE 115, which may be located in a second residence (R2); and a UE 116, which may be a mobile device (M), such as a cell phone, a wireless laptop, a wireless personal digital assistant (PDA), or the like. The gNB 103 provides wireless broadband access to the network 130 for a second plurality of UEs within a coverage area 125 of the gNB 103. The second plurality of UEs includes the UE 115 and the UE 116, as well as subscriber stations (SS, for example, UEs) 117, 118 and 119. In some embodiments, one or more of the gNBs 101-103 may communicate with each other and with the UEs 111-116 using existing wireless communication techniques, and one or more of the UE 111-119 may communicate directly with each other (e.g., UEs 117-119) using other existing or proposed wireless communication techniques.

[0144] Depending on the network type, the term "base station" or "BS" can refer to any component (or collection of components) configured to provide wireless access to a network, such as transmit point (TP), transmit-receive point (TRP), an enhanced (or "evolved") base station (eNodeB or eNB), a 5G base station (gNB), a macrocell, a femtocell, a wireless fidelity (WiFi) access point (AP), or other wirelessly enabled devices. Base stations may provide wireless access in accordance with one or more wireless communication protocols, e.g., 3GPP 5G New Radio (NR), Long Term Evolution (LTE), LTE Advanced (LTE-A), high speed packet access (HSPA), Wi-Fi 802.11a / b / g / n / ac, etc. For the sake of convenience, the various names for a base station-type apparatus and functionality are used interchangeably in this patent document to refer to network infrastructure components that provide wireless access to remote terminals. Also, depending on the network type, the term "user equipment" (UE) can refer to any component such as a mobile station (MS), subscriber station (SS), remote terminal, wireless terminal, receive point, or user device. For the sake of convenience, the various names for a user equipment-type device and functionality are used interchangeably in this patent document to refer to remote wireless equipment that wirelessly accesses a BS, whether the UE is a mobile device (such as a mobile telephone or smartphone) or is normally considered a stationary device (such as a desktop computer or vending machine).

[0145] Dotted lines show the approximate extents of the coverage areas 120 and 125, which are shown as approximately circular for the purposes of illustration and explanation only. It should be clearly understood that the coverage areas associated with gNBs, such as the coverage areas 120 and 125, may have other shapes, including irregular shapes, depending upon the configuration of the gNBs and variations in the radio environment associated with natural and man-made obstructions.

[0146] As described in more detail below, one or more of the UEs 111-119 include circuitry, programing, or a combination thereof. In certain embodiments, and one or more of the gNBs 101-103 includes circuitry, programing, or a combination thereof.

[0147] Although FIG. 1 illustrates one example of a wireless network, various changes may be made to FIG. 1. For example, the wireless network could include any number of gNBs and any number of UEs in any suitable arrangement. Also, the gNB 101 could communicate directly with any number of UEs and provide those UEs with wireless broadband access to the network 130. Similarly, each gNB 102-103 could communicate directly with the network 130 and provide UEs with direct wireless broadband access to the network 130. Further, the gNBs 101, 102, and / or 103 could provide access to other or additional external networks, such as external telephone networks or other types of data networks.

[0148] FIG. 2 illustrates an example base station according to embodiments of the present disclosure. The embodiment of the gNB 102 illustrated in FIG. 2 is for illustration only, and the gNBs 101 and 103 of FIG. 1 could have the same or similar configuration. However, gNBs come in a wide variety of configurations, and FIG. 2 does not limit the scope of the present disclosure to any particular implementation of a gNB.

[0149] As shown in FIG 2, the 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. The gNB 102 also includes a controller / processor 205, a memory 206, and a backhaul or network interface 207.

[0150] The RF transceivers 201a-201n receive, from the antennas 200a-200n, incoming RF signals, such as signals transmitted by UEs in the network 100. The RF transceivers 201a-201n down-convert the incoming RF signals to generate intermediate frequency (IF) or baseband signals. The IF or baseband signals are sent to the RX processing circuitry 204, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. The RX processing circuitry 204 transmits the processed baseband signals to the controller / processor 205 for further processing.

[0151] The TX processing circuitry 203 receives analog or digital data (such as voice data, web data, electronic mail, or interactive video game data) from the controller / processor 205. The TX processing circuitry 203 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate processed baseband or IF signals. The RF transceivers 201a-201n receive the outgoing processed baseband or IF signals from the TX processing circuitry 203 and up-converts the baseband or IF signals to RF signals that are transmitted via the antennas 201a-201n.

[0152] The controller / processor 205 can include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 205 could control the reception of forward channel signals and the transmission of reverse channel signals by the RF transceivers 201a-201n, the RX processing circuitry 204, and the TX processing circuitry 203 in accordance with well-known principles. The controller / processor 205 could support additional functions as well, such as more advanced wireless communication functions.

[0153] For instance, the controller / processor 205 could support beam forming or directional routing operations in which outgoing signals from multiple antennas 200a-200n are weighted differently to effectively steer the outgoing signals in a desired direction. Any of a wide variety of other functions could be supported in the gNB 102 by the controller / processor 205.

[0154] The controller / processor 205 is also capable of executing programs and other processes resident in the memory 206, such as an operating system (OS). The controller / processor 205 can move data into or out of the memory 206 as required by an executing process.

[0155] The controller / processor 205 is also coupled to the backhaul or network interface 207. The backhaul or network interface 207 allows the gNB 102 to communicate with other devices or systems over a backhaul connection or over a network. The interface 207 could support communications over any suitable wired or wireless connection(s). For example, when the gNB 102 is implemented as part of a cellular communication system (such as one supporting 5G, LTE, or LTE-A), the interface 207 could allow the gNB 102 to communicate with other gNBs over a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, the interface 207 could allow the gNB 102 to communicate over a wired or wireless local area network or over a wired or wireless connection to a larger network (such as the Internet). The interface 207 includes any suitable structure supporting communications over a wired or wireless connection, such as an Ethernet or RF transceiver.

[0156] The memory 206 is coupled to the controller / processor 205. Part of the memory 206 could include a random access memory (RAM), and another part of the memory 206 could include a Flash memory or other read only memory (ROM).

[0157] Although FIG. 2 illustrates one example of gNB 102, various changes may be made to FIG. 2. For example, the gNB 102 could include any number of each component shown in FIG. 2. As a particular example, an access point could include a number of interfaces 207, and the controller / processor 205 could support routing functions to route data between different network addresses. As another particular example, while shown as including a single instance of TX processing circuitry 203 and a single instance of RX processing circuitry 204, the gNB 102 could include multiple instances of each (such as one per RF transceiver). Also, various components in FIG. 2 could be combined, further subdivided, or omitted and additional components could be added according to particular needs.

[0158] FIG. 3 illustrates an example user equipment according to embodiments of the present disclosure. The embodiment of the UE 116 illustrated in FIG. 3 is for illustration only, and the UEs 111-115 and 117-119 of FIG. 1 could have the same or similar configuration. However, UEs come in a wide variety of configurations, and FIG. 3 does not limit the scope of the present disclosure to any particular implementation of a UE.

[0159] As shown in FIG. 3, the UE 116 includes an antenna 301, a radio frequency (RF) transceiver 302, TX processing circuitry 303, a microphone 304, and receive (RX) processing circuitry 305. The 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 a memory 311. The memory 311 includes an OS 312 and one or more applications 313.

[0160] The RF transceiver 302 receives, from the antenna 301, an incoming RF signal transmitted by a gNB of the network 100. The RF transceiver 302 down-converts the incoming RF signal to generate an IF or baseband signal. The IF or baseband signal is sent to the RX processing circuitry 305, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. The RX processing circuitry 305 transmits the processed baseband signal to the speaker 306 (such as for voice data) or to the processor 307 for further processing (such as for web browsing data).

[0161] The TX processing circuitry 303 receives analog or digital voice data from the microphone 304 or other outgoing baseband data (such as web data, e-mail, or interactive video game data) from the processor 307. The TX processing circuitry 303 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceiver 302 receives the outgoing processed baseband or IF signal from the TX processing circuitry 303 and up-converts the baseband or IF signal to an RF signal that is transmitted via the antenna 301.

[0162] The processor 307 can include one or more processors or other processing devices and execute the OS 312 stored in the memory 311 in order to control the overall operation of the UE 116. For example, the processor 307 could control the reception of forward channel signals and the transmission of reverse channel signals by the RF transceiver 302, the RX processing circuitry 305, and the TX processing circuitry 303 in accordance with well-known principles. In some embodiments, the processor 307 includes at least one microprocessor or microcontroller.

[0163] The processor 307 is also capable of executing other processes and programs resident in the memory 311, such as processes for channel state information (CSI) reporting on uplink channel. The processor 307 can move data into or out of the memory 311 as required by an executing process. In some embodiments, the processor 307 is configured to execute the applications 313 based on the OS 312 or in response to signals received from gNBs or an operator. The processor 307 is also coupled to the I / O interface 308, which provides the UE 116 with the ability to connect to other devices, such as laptop computers and handheld computers. The I / O interface 308 is the communication path between these accessories and the processor 307.

[0164] The processor 307 is also coupled to the touchscreen display 310. The user of the UE 116 can use the touchscreen display 310 to enter data into the UE 116. The touchscreen display 310 may be a liquid crystal display, light emitting diode display, or other display capable of rendering text and / or at least limited graphics, such as from web sites.

[0165] The memory 311 is coupled to the processor 307. Part of the memory 311 could include RAM, and another part of the memory 311 could include a Flash memory or other ROM.

[0166] Although FIG. 3 illustrates one example of UE 116, various changes may be made to FIG. 3. For example, various components in FIG. 3 could be combined, further subdivided, or omitted and additional components could be added according to particular needs. As a particular example, the processor 307 could be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Also, while FIG. 3 illustrates the UE 116 configured as a mobile telephone or smartphone, UEs could be configured to operate as other types of mobile or stationary devices.

[0167] The text and drawings of this disclosure are provided as examples only to assist in understanding the present disclosure. They should not be construed as limiting the scope of the disclosure in any way. Although certain embodiments and examples have been provided, it will be apparent to those skilled in the art, based upon this disclosure, that changes can be made to the embodiments and examples shown without departing from the scope of the disclosure.

[0168] In this disclosure, the message name is only an example, and other message names may also be used.

[0169] In this disclosure, "first", "second", etc. included in the message name are only used to distinguish one message from another message and do not represent the execution or transmission order.

[0170] In the present disclosure, detailed descriptions of steps irrelevant to the present disclosure are omitted.

[0171] In the present disclosure, the steps in each process can be executed in combination with each other or executed individually. The execution steps of each process are only examples and do not exclude other possible execution steps and / or orders.

[0172] In the present disclosure, the base station may be one of the following types (nor does it exclude other types of equipment that can be used for user equipment access):

[0173] -A Long Term Evolution (LTE) base station;

[0174] -A 5G base station;

[0175] -A 6G base station;

[0176] -A RAN node;

[0177] -A Non-Terrestrial Networks (NTN) base station;

[0178] -A High Altitude Platform Station (HAPS) base station;

[0179] -A Drone base station; and

[0180] -A WIFI Access Point.

[0181] In a wireless network, in order to ensure normal communication between two nodes, the two nodes need to obtain communication-related configuration information, which may be transmitted by one node to the other node or transmitted by other nodes to the two nodes respectively. After receiving the configuration information, each node will configure its own communication module and communicate with another node according to the configuration information (for example, the first node communicates with the second node). In one example, the above two nodes may be a base station and a user equipment respectively, and the configuration information may be transmitted by the base station to the user equipment, or transmitted by the user equipment to the base station; in another example, the above two nodes may be the first user equipment and the second user equipment respectively, and the configuration information may be transmitted by the first user equipment to the second user equipment, or transmitted by the second user equipment to the first user equipment; in another example, the above two nodes may be the first user equipment and the second user equipment respectively, and the above other nodes are base stations, then the configuration information is transmitted by the base station to the first user equipment and the second user equipment respectively. The configuration information may include at least one of the following configurations:

[0182] -Data configuration information, the information including configuration information for the transmitted data, and the 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 type here is only an example, and other types of data are not excluded): radio bearer (RB), Data radio bearer (DRB), Signaling Radio Bearer (SRB), Radio link control bearer (RLC bearer), Session data, Packet Data Unit session (PDU Session) Data, flow data, Quality of Service flow (QoS flow) data, and Internet Protocol (IP) data.

[0183] -Cell configuration information, which includes the configuration information of the cell serving data transmission, and may include the configuration information of one or more cells. The cell(s) may be at least one of the following cell types (the cell type here is only examples, other types of cells are not excluded): Primary Cell (PCell), Special cell (SpCell), Primary Secondary Cell Group Cell (PSCell), Secondary Cell (SCell).

[0184] -Channel configuration information, which includes configuration information of different channels for service data transmission, which may include configuration information of one or more channels. The channel(s) may be at least one of the following channels (the channel type here is only an example, not excluding other types of channels): logical channel, downlink control channel (such as Physical Downlink Control Channel (PDCCH)), downlink shared channel (such as Physical Downlink Shared Channel (PDSCH)), uplink control channel (such as Physical Uplink Control Channel (PUCCH)), uplink shared channel (such as Physical Uplink Shared Control Channel (PUSCH)), Random Access channgel (such as Physical Rondom Access Channel (PRACH)), Broadcast Control Channel (MCCH) (such as Multicast / Broadcast Services Control Channel), Broadcast Data Traffic Channel (such as Multicast / Broadcast Services Traffic Channel (MTCH)), Sideline Control Channel (Physical Sidelink Contro Channle (PSCCH)), Sidelink shared channel (such as Physical Sidelink Shared Channel (PSSCH)), Sidelink Feedback Channel (such as Physical Sidelink Feedback Channel (PSFCH)), Backhaul Link Channel (such as a backhaul wireless link control channel (e.g., backhaul RLC channel)), Sidelink Channel (such as a Sidelink RLC channel), Radio Link Control Channel (such as RLC channel (RLC CH)).

[0185] -Measurement configuration information, which includes the configuration information required by the node when performing measurements.

[0186] The above configuration information may include configuration information for different types of data / cells / channels / measurements, etc., which results in larger signaling overhead. In order to reduce the signaling overhead brought by these configuration information, the present invention provides a configuration method based on reference configuration (or configuration template). In this method, as shown in Figure 4, the configuration information required by the nodes in the wireless network is generated from reference configuration and delta configuration. The reference configuration may be reference configuration for data, reference configuration for a cell, reference configuration for a channel, reference configuration for measurement, etc., and the delta configuration may include one or more delta configurations, and each delta configuration includes configuration information different from the corresponding reference configuration. As shown in Figure 4, the reference configuration and the delta configuration 1 / 2 / 3 respectively generate configurations 1 / 2 / 3. In this way, when configuring a node, it is only necessary to send one reference configuration and multiple delta configurations, instead of sending all the configurations 1 / 2 / 3 to the node. Since the delta configuration 1 / 2 / 3 only includes information that is different from the reference configuration, its size is reduced than configuration 1 / 2 / 3, so the signaling overhead of configuring the node can be reduced. In one example, if a node in the wireless network receives one reference configuration of data, and two delta configurations for two different bearers (e.g., the delta configuration of Bearer 1 and the delta configuration of Bearer 2), the node can generate the complete configuration of Bearer 1 based on the reference configuration and the delta configuration of Bearer 1, and generate the complete configuration of Bearer 2 based on the reference configuration and the delta configuration of Bearer 2.

[0187] In the present invention, "bearer" may indicate 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 bearer), Session data, Packet data unit session (PDU Session) Data, flow data, Quality of Service flow (QoS flow) data, Internet Protocol (IP) data. Therefore, in the following description, "bearer" may be replaced with at least one of "radio bearer", "data radio bearer", "signaling radio bearer", "RLC bearer", "PDU session", "flow", "QoS flow" and "IP".

[0188] In the present invention, the reference configuration may also be called a template configuration, a configuration template, or other names.

[0189] In the present invention, the reference configuration information may include at least one of the following information:

[0190] -Reference configuration identification information, or configuration template identification information, which identifies one reference configuration. In one example, the reference configuration is all configurations included in the following "configuration information". In another example, the reference configuration may be a combination of one or more of the following reference configurations: such as radio bearer reference configuration information, RLC bearer reference configuration information, bearer reference configuration information, cell reference configuration information, primary cell reference configuration information, and secondary cell reference configuration information, etc.

[0191] -Node configuration information, the information including configuration information as reference configuration, the information includes at least one of the following information:

[0277] The present invention includes the following process, as shown in Figure 5:

[0278] Step 1-1: The first node transmits a first configuration message to the second node, the message including the configuration information required to configure the second node, and the message including at least one of the following information:

[0279] -First configuration information including reference configuration information required for generating the configuration of the second node, and the detailed description of the information can be found in the above "reference configuration information".

[0280] -Second configuration information including configuration information for use by the second node, the second configuration information being usable by the second node to configure data transmission in the wireless network. In one example, the information includes the complete / full configuration information for the second node. In another example, the information includes the delta configuration information relative to the above-mentioned "first configuration information". After receiving this information, the second node needs to combine the above-mentioned first configuration information to generate the complete configuration information for the second node. This information may include multiple sets of configuration information (i.e., configuration information list). For each set of configuration information (i.e., an entry in the configuration information list), the information includes at least one of the following information:

[0281] --Configuration identification information identifying a set of configuration information

[0282] --Third configuration information including a set of configuration information to be used by the second node to configure data transmission in the wireless network.

[0283] ---Radio Bearer Configuration Information

[0284] ---RLC Bearer Configuration Information

[0285] ---Bearer Configuration Information

[0286] ---Cell Configuration Information

[0287] ---RLC Channel Configuration Information

[0288] ---Channel Configuration Information

[0289] ---Measurement Configuration Information

[0290] --Reference configuration indication information indicating that the set of configuration information (or the above-mentioned "third configuration information") identified by the above-mentioned "configuration identification information" is reference configuration information, and other sets of configuration information can be generated based on the reference configuration information. Further, the indication information may also include identification information of the reference configuration, or the indication information may be identification information of the reference configuration.

[0291] --Associated configuration indication information indicating identification information of the associated reference configuration. In one example, when one of the multiple sets of configuration information included in the above-mentioned "second configuration information" is used as reference configuration, this information is the above-mentioned "configuration identification information" corresponding to the set of configuration information. In another example, when the above-mentioned "first configuration information" is used as reference configuration, the information is the identification information included 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", "measurement reference configuration identification information", "measurement objective 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 reference configuration information.

[0292] --Delta configuration information includes different information between the set of configuration information identified by the above-mentioned "configuration identification information" and the reference configuration information. The second node combines this information with the reference configuration information to obtain the configuration information required by the second node. The information includes at least one of the following information:

[0293] ---Radio Bearer Configuration Information

[0294] ---RLC Bearer Configuration Information

[0295] ---Bearer Configuration Information

[0296] ---Cell Configuration Information

[0297] ---RLC Channel Configuration Information

[0298] ---Channel Configuration Information

[0299] ---Measurement Configuration Information

[0300] Step 1-2: The second node obtains reference configuration information according to 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 information:

[0301] ---Radio Bearer Configuration Information

[0302] ---RLC Bearer Configuration Information

[0303] ---Bearer Configuration Information

[0304] ---Cell Configuration Information

[0305] ---RLC Channel Configuration Information

[0306] ---Channel Configuration Information

[0307] ---Measurement Configuration Information

[0308] In this step, the second node includes the following actions:

[0309] -Obtaining Reference Configuration Information

[0310] When the above-mentioned "first configuration message" includes the above-mentioned "first configuration information", the second node uses the "first configuration information" as the reference configuration information; when the above first configuration message includes "reference configuration indication information", the second node uses the "third configuration information" corresponding to the "reference configuration indication information" as the reference configuration information.

[0311] -Generating the required configuration information. This behaviour has the following two implementations:

[0312] --Implementation 1: generating configuration information based on "first configuration information"

[0313] In this implementation, the second node provides reference configuration information through the above-mentioned "first configuration information". When the second node receives the above-mentioned first configuration message, for any set of configuration information included in the "second configuration information", if the configuration information includes the "identification information of the associated configuration", the second node uses the configuration information identified by the "associated configuration identification information" in the above-mentioned "first configuration information" as the reference configuration information, and then combines the "delta configuration information" to generate the configuration information required by the second node. If the configuration information does not include the "associated configuration identification information", the second node uses the above-mentioned "first configuration information" as the reference configuration information, and then combines the "delta configuration information" to generate the configuration information required by the second node.

[0314] --Implementation 2: generating configuration information based on the "third configuration information" corresponding to the "reference configuration indication information"

[0315] In this implementation, the second node uses the set of configuration information in the above-mentioned "second configuration information" as reference configuration information, and the set of configuration information includes the above-mentioned "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 above-mentioned "second configuration information". Further, for other sets of configuration information included in the above-mentioned "second configuration information" (excluding the set of configuration information including the above-mentioned "reference configuration indication information"), the second node generates the configuration information for the second node according to the above-mentioned reference configuration information and "delta configuration information".

[0316] In the above steps, a possible implementation is that the above-mentioned "first configuration information" and "second configuration information" are transmitted through the same message. After receiving the message, the second node can generate the configuration information for the second node. Another possible implementation is that the above-mentioned "first configuration information" is sent to the second node through a message, and then the above-mentioned "second configuration information" is sent to the second node through another message. Another further possible implementation is that the above-mentioned first configuration message only includes the above-mentioned "second configuration information", one set of configuration information in the "second configuration information" can be used as reference configuration, and other sets of configuration information are generated based on the reference configuration.

[0317] The above-mentioned first configuration message may be a Radio Resource Control (RRC) message, such as an RRC Reconfiguration message, an RRC Setup message, an RRC resume message, a RRC Reconfiguration sidelink message, or other types of messages.

[0318] The beneficial effect of the above process is that by configuring the reference configuration and the delta configuration, the signaling overhead of sending configuration information is reduced and the efficiency of wireless resource utilization is improved.

[0319] In conjunction with specific configuration information below, the present invention includes the following possible embodiments. In the following embodiments, if the first node provides only one reference configuration information, the "associated configuration identification information " may not be sent to the second node, and the second node may generate the configuration information for the second node based on the reference configuration information and the received one or more delta configuration information. In the following embodiments, the second node may receive at least one delta configuration information, and the second node combines the delta configuration information with the corresponding reference configuration to generate at least one configuration information for the second node. The configuration information for the second node may be at least one of the following information (in one example, when the configuration information for the second node is a combination of multiple of the following information, the configuration information of a second node may be configuration information of a cell group):

[0320] ---Radio Bearer Configuration Information

[0321] ---RLC Bearer Configuration Information

[0322] ---Bearer Configuration Information

[0323] ---Cell Configuration Information

[0324] ---RLC Channel Configuration Information

[0325] ---Channel Configuration Information

[0326] ---Measurement Configuration Information

[0327] Embodiment 1: Reference configuration information includes multiple different types of configurations

[0328] In this embodiment, the reference configuration information includes at least one of the following information:

[0329] --Reference Configuration Identification Information

[0330] --Node configuration information. The configuration information includes at least one of the following information:

[0331] ---Radio Bearer Configuration Information

[0332] ---RLC Bearer Configuration Information

[0333] ---Bearer Configuration Information

[0334] ---Cell Configuration Information

[0335] ---RLC Channel Configuration Information

[0336] ---Channel Configuration Information

[0337] ---Measurement Configuration Information

[0338] In one example, the above reference configuration information may be configuration information of a cell group (such as Cell Group Config).

[0339] -When the reference configuration is transmitted through the above "first configuration information",

[0340] The second node may receive the "first configuration information" through a first message, wherein the first message is specifically used to send reference configuration information, and the first message may include one or more reference configuration information, each reference configuration information being identified by corresponding "reference configuration identification information". In one example, the first message further includes the above-mentioned "second configuration information". In another example, the above-mentioned "second configuration information" may be sent to the second node through a second message. The "second configuration information" may include one or more sets of configuration information (in one example, the set of configuration information may be the configuration information of a cell group), and each set of configuration information includes at least one of "configuration identification information", "associated configuration identification information" (this information is the identification of reference configuration information in the above-mentioned "first configuration information", and the second node can learn the reference configuration information based on this information), and "delta configuration information". The second node generates its required set of configuration information (such as configuration information of a cell group) based on "delta configuration information" and corresponding reference configuration information. In one implementation, the second node is to generate configuration information for multiple cell groups, so the above-mentioned "first configuration information" includes one or more cell group reference configuration information, and the above-mentioned "second configuration information" includes each set of configuration information corresponds to a cell group configured to the second node, and the second node will generate a complete configuration of a cell group configured to the second node based on the cell group reference configuration information in the "first configuration information" and the "delta configuration information" in the "second configuration information".

[0341] -When the reference configuration is transmitted through the above "second configuration information",

[0342] The second node may receive "second configuration information" through the first message, which may include one or more sets of configuration information. If one of the sets of configuration information includes "reference configuration indication information", then the set of configuration information (including at least one of "configuration identification information" and "third configuration information") can be used as reference configuration information. If one of the sets of configuration information includes "associated configuration identification information" (the set of configuration information further includes at least one of "configuration identification information" and "delta 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 "delta configuration information" included in the set of configuration information. In one implementation, the second node is to generate configuration information of multiple cell groups, and the above-mentioned "second configuration information" includes cell group configuration information of one or more cell groups configured to the second node. In one example, the "configuration identification information" in each cell group configuration information may be the identification information of the cell group. The cell group configuration information that can be used as reference configuration includes the above-mentioned "reference configuration indication information", while the cell group configuration information that cannot be used as reference configuration includes "associated configuration identification information" (this information includes identification of the cell group configuration information corresponding to the reference configuration, and in one example, the information is the identification information of the cell group) and "delta configuration information". Therefore, the second node can combine the reference configuration and the delta configuration information to generate a complete configuration of a cell group.

[0353] The second node may receive the "first configuration information" through a first message, wherein the first message is specifically used to send reference configuration information, and the first message may include one or more radio bearer reference configuration information, each reference configuration Information being identified by corresponding "radio bearer reference configuration identification information". In one example, the first message further includes the above-mentioned "second configuration information". In another example, the above-mentioned "second configuration information" may be sent to the second node through a second message. The "second configuration information" may include one or more radio bearer configuration information, and each radio bearer configuration information includes at least one of "configuration identification information" (in one example, the information is the identification information of the radio bearer), "associated configuration identification information "(this information is a radio bearer reference configuration identification information in the above-mentioned "first configuration information", and the second node can learn the reference configuration information based on this information), and "delta configuration information "(in one example, this information includes "radio bearer configuration information", and further, this information only includes information different from the associated radio bearer reference configuration information), and the second node generates configuration information of a radio bearer it requires based on the" delta configuration information "and the corresponding reference configuration information.

[0354] -When the reference configuration information is transmitted through the above-mentioned "second configuration information",

[0355] The second node may receive "second configuration information" through the first message, and the "second configuration information" may include one or more radio bearer configuration information, which is used to configure one or more radio bearers of the second node. If one of the radio bearer configuration information includes "reference configuration indication information", the configuration information can be used as reference configuration information, and the configuration information includes at least one of "configuration identification information" (in one example, the information is the identification information of the radio bearer)), and "third configuration information" (including "radio bearer configuration information"); if one of the radio bearer configuration information includes "associated configuration identification information" (the radio bearer configuration information further includes at least one of "configuration identification information" (in one example, the information is the identification information of the radio bearer), and "delta configuration information" (in one example, the information includes "radio bearer configuration information", and further, the information only includes information different from the associated radio bearer reference configuration information)), then the second node can determine the associated radio bearer reference configuration information based on the information, and generate configuration information of a radio bearer required by the second node based on the reference configuration information and the "delta configuration information".
