Description

Technical Field

[0001] This disclosure relates to wireless communication technology, and more particularly to methods for execution by nodes 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 improve user equipment (UE) throughput, dual connectivity technology has become a crucial approach, allowing a single UE to establish connections with two base stations simultaneously and transmit data. However, because a UE needs to maintain connections with two base stations, dual connectivity increases the complexity of UE resource management and mobility management, thus increasing UE design complexity. In future 6G systems, reducing UE complexity while simultaneously improving throughput is a pressing issue that needs to be addressed. Summary of the Invention

Therefore, it will be apparent to those skilled in the art that the following description of various embodiments of this disclosure is for illustrative purposes only and not for limiting the purpose of this disclosure as defined in the appended claims and their equivalents.

[0066] It should be understood that the singular forms of “one,” “an,” and “the” include plural references unless the context clearly indicates otherwise. Thus, for example, the reference to “component surface” includes one or more such surfaces.

[0067] The terms “comprising” or “may include” refer to the presence of a corresponding disclosed function, operation, or component that may be used in the various embodiments of this disclosure, rather than limiting the presence of one or more additional functions, operations, or features. Furthermore, the terms “comprising” or “having” may be interpreted as indicating certain characteristics, numbers, steps, operations, constituent elements, components, or combinations thereof, but should not be construed as excluding the possibility of the presence of one or more other characteristics, numbers, steps, operations, constituent elements, components, or combinations thereof.

[0069] Unless otherwise defined, all terms used in this disclosure (including technical or scientific terms) have the same meaning as understood by one of those skilled in the art as described herein. Common terms as defined in dictionaries are to be interpreted as having a meaning consistent with the context in the relevant technical field and should not be interpreted ideally or overly formally unless expressly defined in this disclosure.

[0070] 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.

[0071] 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.

[0072] like Figure 1 As 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.

[0073] 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 UE 111116 using existing wireless communication technologies, and one or more of UEs 111 and 119 may communicate directly with each other (e.g., UE 117 and 119) using other existing or proposed wireless communication technologies.

[0074] 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).

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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).

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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).

[0091] 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.

[0092] 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.

[0093] 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.

[0094] The processor 307 is also connected to the touchscreen display 310. The user of the UE 116 can use the touchscreen display 310 to input data into the UE 116. The touchscreen display 310 can be a liquid crystal display, a light-emitting diode display, or other display capable of rendering text and / or at least limited graphics such as those from a website.

[0095] Memory 311 is connected to processor 307. A portion of memory 311 may include RAM, and another portion of memory 311 may include flash memory or other ROM.

[0096] although Figure 3 An example of UE 116 is shown, but it is possible to modify it. Figure 3 Make various changes. For example, Figure 3 The various components can be combined, further subdivided, or omitted, and additional components can be added as needed. As a specific example, processor 307 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Moreover, although... Figure 3 The UE 116 is shown configured as a mobile phone or smartphone, but the UE can be configured to operate as other types of mobile or fixed devices.

[0100] Detailed descriptions of steps that are not relevant to this disclosure have been omitted in this disclosure.

[0101] In this disclosure, the steps in each process can be executed in combination or individually. The execution steps of each process are merely examples, and other possible execution steps and / or sequences are not excluded.

[0102] In this disclosure, the base station can be one of the following types (and other types of devices that can be used for user equipment access are not excluded):

[0103] ■ Long Term Evolution (LTE) base stations;

[0104] ■5G base station;

[0105] ■6G base station

[0106] ■RAN node;

[0107] ■ Non-Terrestrial Networks (NTN) base stations;

[0108] ■ High Altitude Platform Station (HAPS) base station;

[0109] ■ Drone base station; and

[0110] ■WIFI access point.

[0111] In wireless networks, to improve the throughput of user equipment, the network can configure multiple different carriers for the user equipment, thereby allowing it to transmit data on multiple cells. For example... Figure 4 As shown in (a), one implementation of this method is carrier aggregation (CA), where multiple cells configured for a user equipment belong to a single base station or a distributed unit of a base station. In one example, these cells belong to the same cell group. Another implementation of this method is dual-connectivity (DC), such as... Figure 4(b) In this case, the multiple cells configured for the user equipment belong to two different base stations or two different distribution units (these two different distribution units may belong to the same base station or different base stations). Each node's cells belong to the same cell group. Therefore, the user equipment in the diagram is served by two different cell groups, and the cells within each cell group belong to one node. Further, another implementation of this method is Multi-Connectivity (MC), where the multiple cells configured for the user equipment belong to at least two different base stations or at least two different distribution units (these at least two different distribution units may belong to the same base station or different base stations). Among these methods, carrier aggregation has higher spectral efficiency. This is because the resources of different cells can be flexibly scheduled by a single base station or a single distribution unit, while in dual-connectivity / multi-connectivity mechanisms, each base station connected to the user equipment can only schedule resources from a portion of the cells, resulting in dual-connectivity / multi-connectivity failing to fully utilize the spectral resources allocated to the user equipment. Moreover, compared to dual-connectivity / multi-connectivity, carrier aggregation has lower complexity (including network-side complexity and user-side complexity). To fully leverage the advantages of carrier aggregation technology, how to implement carrier aggregation among multiple base stations is an important research direction for future 6G systems. This invention provides a method for implementing inter-node carrier aggregation. Specifically, as shown... Figure 5 As shown, taking carrier aggregation with two base stations as an example, a user equipment (UE) is configured with multiple serving cells, some belonging to base station 1 and some to base station 2. Unlike dual connectivity / multi-connectivity, these multiple serving cells are configured to the UE via carrier aggregation (in one example, these cells belong to the same cell group). Therefore, the UE cannot perceive that these serving cells belong to different base stations, which simplifies the UE's configuration signaling. Furthermore, to achieve the performance of carrier aggregation, signaling interaction occurs between the two or more base stations serving the UE. Besides the UE, this invention may involve the following possible nodes:

[0112] ■ First node: base station, or centralized unit of base station, or control plane portion of centralized unit of base station. In one example, the first node may be a first base station, or centralized unit of first base station, or control plane portion of centralized unit of first base station.

[0113] ■ Second node: A base station, or a centralized unit of a base station, or a control plane portion of a centralized unit of a base station. This node differs from the first node. In one example, the first node may be a second base station, or a centralized unit of a second base station, or a control plane portion of a centralized unit of a second base station.

[0114] ■ Third Node: The distribution unit of the base station; in one example, the third node is the first distribution unit.

[0115] ■ Fourth Node: The distribution unit of the base station. This node is a distribution unit that is different from the third node. In one example, the fourth node is the second distribution unit.

[0116] In one example, when the first node is a centralized unit of a base station or the control plane portion of a centralized unit of a base station, the third and fourth nodes are distributed units connected to the first node. In another example, when the first and second nodes are centralized units of a base station or the control plane portion of a centralized unit of a base station, the third node is a distributed unit connected to the first node, and the fourth node is a distributed unit connected to the second node. Furthermore, when the user equipment is configured with carrier aggregation between multiple base stations or multiple distributed units, the signaling interaction between base stations (such as signaling interaction between the first and second nodes) in this invention can be used for interaction between any two base stations, or for signaling interaction between a centralized unit and a distributed unit of a base station (such as the signaling interaction between the first and third / fourth nodes, or the signaling interaction between the first and third nodes and between the second and fourth nodes can be used for signaling interaction between any centralized unit and a distributed unit).

[0117] In this invention, the uplink channel is a channel used to transmit specific uplink control information, such as a Scheduling Request (SR), a Channel Quality Indicator (CQI), and acknowledgment / negative acknowledgment (ACK / NACK) information for a Hybrid Automatic Repeat reQuest (HARQ). In one example, the uplink channel is a Physical Uplink Control Channel (PUCCH); in another example, it is a Physical Uplink Shared Channel (PUSCH). The uplink channel can also be other types of channels, such as physical channels, logical channels, etc.

[0118] In this invention, the serving cell of a user equipment (UE) can be divided into two categories: cells that include the aforementioned "uplink channel" (such as the first cell) and cells that do not include the aforementioned "uplink channel" (such as the second cell). These two types of cells may belong to the same node or different nodes. For the first cell, the UE can use the uplink channel of that cell to send uplink control information, such as sending SR to request resources for uplink data transmission, sending CQI to provide the network side with the UE's measurements of the first cell, and sending HARQ ACK / NACK to indicate whether downlink data has been correctly received by the UE. For the second cell, since it does not contain the aforementioned "uplink channel," the user equipment cannot send the aforementioned uplink control information on the second cell. For example, it cannot send SR through the second cell, cannot send CQI through the second cell (e.g., the CQI information of the second cell cannot be sent to the network side through the second cell), and cannot send HARQ ACK / NACK through the second cell (e.g., the data received by the user equipment in the second cell cannot be used to inform the network side whether the user equipment has correctly received the data). Through the configuration method of the present invention, an associated cell can be configured for the second cell. An example of such an associated cell is the first cell. The user equipment can send the aforementioned uplink control information through the uplink channel on the first cell. Furthermore, the first cell and the second cell may belong to the same node or different nodes.

[0119] In this invention, the data stream indicates all the data that the user equipment needs to transmit. The data included in this data stream may be at least one of the following types: 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) flow data. In one example, the user equipment's data stream may include all the DRBs or all the RBs configured for the user equipment. When the user equipment is configured with serving cells belonging to different nodes, the aforementioned user equipment data stream may be transmitted in the serving cells of different nodes, resulting in different amounts of user equipment data streams needing to be transmitted by different nodes, leading to different resource allocations for different nodes. For example, when a user equipment (UE) is configured to serve two different base stations, the UE's data flow may be allocated differently between the two base stations. One allocation might be: one base station handles 80% of the data flow, and the other handles 20%; another might be: one base station handles 40% of the data flow, and the other handles 60%. These two allocations result in different resource allocations on the two base stations. The method in this invention can dynamically adjust the UE's resource allocation across different nodes based on the data flow allocation. In this invention, to represent the different data flow allocation methods between nodes, an identification information (such as the data flow identification information and data flow configuration identification information described below) can be used to indicate an allocation method, and the uplink channel resource allocation configuration is associated with this identification information. The UE can determine the uplink channel resource allocation configuration through the identification information indicated by the network (see the following description for details). Dynamically change the uplink signal of the user equipment Allocation of Dao resources (as described in the text).

[0120] Taking the example of multiple cells configured for a user equipment belonging to two different base stations, the present invention includes the following process, such as... Figure 6 As shown:

[0121] Step 1-1: The first node (first base station) sends a first request message to the second node (second base station). This message requests the configuration of multiple different serving cells for the user equipment. In one example, some of these serving cells belong to the first node, and others belong to the second node. This message is used to configure carrier aggregation (such as inter-node carrier aggregation, inter-base station carrier aggregation, node aggregation, and base station aggregation) for the user equipment using serving cells belonging to different nodes. This message includes at least one of the following information:

[0122] ■ The first instruction information instructs the user equipment (UE) to configure multiple serving cells belonging to different nodes. This instruction information can be explicit or implicit. Furthermore, these multiple serving cells are configured to the UE using carrier aggregation (i.e., the UE is unaware that these cells belong to different nodes). In one example, this information indicates that the multiple serving cells configured for the UE belong to two base stations or at least two base stations; in another example, this information indicates that the UE is configured with inter-base station / inter-node carrier aggregation or cross-base station carrier aggregation (Inter-base station / node CA); in yet another example, this information indicates that the UE is configured with inter-base station aggregation or cross-base station aggregation (Inter-base station aggregation); in yet another example, this information indicates that the UE is configured with inter-node aggregation or cross-node aggregation (Inter-node aggregation); in one example, this information indicates that the multiple serving cells configured for the UE belong to two distribution units or at least two distribution units. Upon receiving this information, the second node can learn that multiple serving cells belonging to different nodes need to be configured for the UE, and thus can determine which configurations the second node needs to generate and which configurations from the first node should be adopted. The benefit of this information is that it reduces unnecessary configuration, thereby reducing the signaling overhead of configuring user equipment.

[0123] ■ Identification request information, which indicates the identification-related information used by the second node when configuring user equipment. In one example (Implementation Method 1), this information is allocated by the first node to the second node, that is, the second node allocates identification information to the user equipment based on this information. In another example (Implementation Method 2), this information indicates the identification-related range information allocated by the first node to the second node. After receiving this information, the second node allocates identification information to the user equipment based on this information. In yet another example (Implementation Method 3), this information indicates a portion of the identification information allocated by the first node to the second node (such as the prefix information, i.e., the first few bits of the identification information). The second node then generates other information in the identification information (such as the other bits of the identification information excluding the prefix portion) based on this information. In order to configure user equipment belonging to cells of multiple different nodes, some identification information needs to be uniformly set by the nodes to avoid conflicts in the identification information used by the nodes. The beneficial effect of this information is to ensure that nodes use unified identification information to configure user equipment and avoid configuration conflicts. This information includes at least one of the following:

[0124] ■ First identification information, which indicates the identification information assigned by the first node to the second node or the identification information that the first node expects the second node to use. Upon receiving this information, the second node will assign identification information to the user equipment based on this information. Further, optionally, in the feedback message sent by the second node (as described in steps 1-2 below), the second node may also indicate whether it has used the identification information or indicate the identification information used by the second node. This information includes at least one of the following:

[0125] ◆ User equipment identification information, which identifies the configured user equipment, such as the Cell-Radio Network Temporary Identifier (C-RNTI).

[0126] ◆ Cell identification information: This information indicates the cell identification information configured for the user equipment. This cell can be the cell served by the second node. In one example, this information is the cell index.

[0127] ◆ Logical channel identification information, which indicates the logical channel of the user equipment, such as logical channelidentity.

[0128] ◆ Logical channel group identification information, which indicates the identification information of the logical channel group of the user equipment, such as logical channel group identity. A logical channel group may contain at least one logical channel.

[0129] ◆Identification information of the scheduling request: This information indicates the identification information of the resource requested by the user equipment, such as the scheduling request identity. ◆Identification information of the timing advance group: This information indicates the identification information of the timing advance group of the user equipment, such as the timing advance group (TAG).

[0130] ◆Energy-saving configuration identification information: This information indicates the identifier of the energy-saving configuration of the user equipment. In one example, the energy-saving configuration can be a discontinuous reception configuration (such as DRX configuration) or a discontinuous reception group configuration (such as DRX group configuration).

[0131] ■ First identification range information, which indicates the range of identification information that the first node allocates to the second node, or the range of identification information that the first node expects the second node to use, or available identification information (such as a list of available identification information). Upon receiving this information, the second node allocates identification information to the user equipment based on this information, the allocated identification information being selected from the range indicated by the range information; furthermore, in the feedback message sent by the second node (as described in steps 1-2 below), the second node may also indicate the identification information used by the second node. This information includes at least one of the following:

[0132] ◆ User equipment identification range information, which indicates the range of identification information configured for the user equipment.

[0133] ◆Cell Identifier Range Information: This information indicates the range of the cell identifier configured for user equipment.

[0134] ◆ Logical channel identifier range information, which indicates the range of logical channel identifiers configured for the user equipment.

[0135] ◆ Range information for logical channel group identifiers, which indicates the range of logical channel group identifiers configured for user equipment.

[0137] ◆Range information for timing advance group identifiers, which indicates the range of timing advance group identifiers configured for user equipment.

[0138] ◆ Range information of energy-saving configuration identifier. This information indicates the range of energy-saving configuration identifiers for the user equipment. In one example, the energy-saving configuration can be a discontinuous reception configuration (such as DRX configuration) or a discontinuous reception group configuration (such as DRX group configuration).

[0139] The range information mentioned above may include at least one of the following: identifier list information (which contains at least one identifier; in one example, when the information contains multiple identifiers, the multiple identifiers may be non-contiguous), start information (i.e., start position information, such as the start information of an identifier), end information (i.e., end position information, such as the end information of an identifier), and length information (i.e., the length information of the range, such as the number of identifiers).

[0140] ■ The first part of the identification information indicates a portion of the identification information that the first node allocates to the second node, or a portion of the identification information that the first node expects the second node to use, or a portion of the available identification information. In one example, this portion of information may be a prefix of the identification; in another example, it may be a suffix of the identification; and in yet another example, it may be information at a specific bit position (e.g., indicated by a bitmap; for example, for a 5-bit identification information, if the bitmap corresponding to a given portion of information is "10101", it means that the information contained in the first part of the identification information is the information at the 1st / 3rd / 5th bit position, or the information at the 2nd / 4th bit position). After receiving this information, the second node will allocate other portions of the identification information (i.e., information not included in the first part of the identification information) to the user equipment based on this information.

[0141] Furthermore, in the feedback message sent by the second node (as described in steps 1-2 below), the second node may also indicate the identification information used by the second node, or indicate a portion of the identification information used by the second node (such as information not included in the first portion of the identification information). This information includes at least one of the following:

[0142] ◆The first part of the user equipment identification information indicates the partial identification information configured for the user equipment.

[0143] ◆The first part of the cell identifier information indicates the partial information of the cell identifier configured for user equipment.

[0144] ◆The first part of the logical channel identifier information indicates the partial information of the logical channel identifier configured for the user equipment.

[0145] ◆The first part of the logical channel group identifier information indicates the portion of the logical channel group identifier configured for the user equipment.

[0146] ◆The first part of the scheduling request identifier indicates partial information about the scheduling request resource identifier configured for the user equipment.

[0147] ◆The first part of the timing advance group identifier information indicates the partial information of the timing advance group identifier configured for the user equipment.

[0148] ◆The first part of the energy-saving configuration identifier indicates partial information about the user equipment's energy-saving configuration identifier. In one example, the energy-saving configuration may be a discontinuous reception configuration (such as DRX configuration) or a discontinuous reception group configuration (such as DRX group configuration).

[0149] ■ First configuration request information, which contains the configuration information required when requesting the second node to serve the user equipment. After receiving this information, the second node will determine the configuration information required to serve the user equipment based on the resource status of the second node, and will feed back the configuration information at the second node in steps 1-2 below. This information includes at least one of the following:

[0150] ■ Information related to the data flow, which includes information about the data flow requesting the second node to serve the user equipment. The beneficial effect of this information is that it indicates the data flow of the user equipment requiring service from the second node, thereby helping the second node configure appropriate resources to serve the user equipment, reducing resource waste. Furthermore, the second node can generate different configurations based on different data flows, facilitating dynamic changes to the user equipment configuration and reducing signaling overhead during user equipment configuration. The data contained in this data flow can be at least one of the following types (the data types here are just examples and other types are not excluded): radio bearer (RB), data radio bearer (DRB), signalalling radio bearer (SRB), radio link control bearer (RLCbearer), session data, packet data unit session (PDUSession) data, flow data, quality of service flow (QoS flow) data, and Internet Protocol (IP) flow data. In one example, the information can be a list containing one or more data stream-related information. Further, this data stream-related information can relate to the same data (e.g., the same one or more DRBs) or different data (e.g., different one or more DRBs). For a single data stream-related information, the information includes at least one of the following: ◆ Data stream identification information, or data stream configuration identification information, which identifies the data stream or data stream configuration requesting the second node's service, such as a Traffic(configuration) identifier; ◆ Data stream volume indication information, which indicates the amount of data requesting the second node's service. In one example, this information is percentage information or absolute value information, i.e., the percentage of the data volume requesting the second node's service out of the total data volume, or the absolute amount of data. Further, the information can also be a list containing one or more data stream volume indications, each indicating the amount of data requesting the second node's service. After receiving this information, the second node can generate different configurations based on different data volumes.

[0151] ◆ Quality of Service (QoS) parameter information for the data stream. This information indicates the QoS parameters of the data stream requesting service from the second node. Further, this information can be a list containing QoS parameter information for one or more data streams. Each QoS parameter indicates the QoS parameters of the data stream requesting service from the second node. Upon receiving this information, the second node can generate different configurations based on the different QoS parameters.

After receiving this information, the second node can generate different configurations based on different QoS parameters.

[0158] ● Data volume indication information, which indicates the volume of a type of data requested by the second node. In one example, this information is a percentage or absolute value, that is, the percentage of the total data volume of this type of data requested by the second node, or the absolute data volume; further, this information can also be a list containing one or more data volume indication information, each indicating the volume of data requested by the second node. After receiving this information, the second node can generate different configurations based on different data volumes.

[0159] ■ Information related to the serving cell, including information about the cell for which the second node requests service for the user equipment. In one example, the cell indicated by this information is a cell selected by the first node that needs to be configured by the second node for the user equipment; in another example, the cell indicated by this information is a cell that the first node requests the second node to configure for the user equipment; in yet another example, the cell indicated by this information is a cell provided by the first node to the second node and measured by the user equipment, from which the second node selects a suitable cell to configure for the user equipment. For a single cell, this information includes at least one of the following:

[0160] ◆First Community Signage Information

[0161] ◆ Cell measurement information, which includes measurement results for the cell (such as the cell indicated in the "First Cell Identification Information" above), such as Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Received Signal Strength Indication (RSSI), and Signal-to-Inference Plus Noise Ratio (SINR). In one example, this measurement result may be from Layer 3, while in another example, it may be from Layer 1.

[0162] ◆Indication information for the first cell type, which indicates the type of cell (such as the cell indicated in the "First Cell Identification Information" above) configured for the user equipment. In one example, this information indicates a primary cell; in another example, it indicates a primary secondary cell (or primary secondary cell group cell); in yet another example, it indicates a secondary cell; in yet another example, it indicates a PUCCH cell (i.e., a cell containing a PUCCH); and in yet another example, it indicates a non-PUCCH cell (i.e., a cell not containing a PUCCH).

[0163] ◆ First uplink channel indication information, which indicates whether the cell configured for the user equipment (such as the cell indicated by the "First Cell Identification Information" above) contains an uplink channel. In one example, the uplink channel may be a PUCCH; in another example, it may be a PUSCH; and in yet another example, it may be a channel containing specific uplink control information.

This information includes at least one of the following:

[0165] ● The identification information of the first associated cell, which indicates the cell where the associated uplink channel is located. In one example, the cell indicated by this information may not be the cell served by the second node. Therefore, during data transmission between the user equipment and the second node, if the user equipment needs to send information on the uplink channel (PUCCH) (such as SR, CQI, HARQ ACK / NACK, which are used to facilitate data transmission between the user equipment and the second node), the user equipment needs to send information on the uplink channel of the cell indicated by this information.

[0166] ● Priority indication information: This information indicates the priority of the uplink channel used by the user equipment. This uplink channel is the uplink channel on the cell indicated by the aforementioned "Identification Information of the First Associated Cell". Further, the aforementioned "First Associated Uplink Channel Indication Information" can also be a list of cells containing one or more associated cells. Optionally, the order of these cells in the list also indicates their priority; for example, cells further up in the list (at the top) have higher priority, or cells further down the list (at the bottom) have higher priority.

[0167] ■ Information related to resource requests, including details about the resources requested from the second node, which the second node can use to allocate resources to the user equipment. The advantage of this information is that the first node can determine the resource allocation for the second node based on the data volume of the user equipment, reducing unnecessary resource waste. This information includes at least one of the following:

[0168] ◆Community signage information

[0169] ◆Uplink channel resource request information, indicating the uplink channel resources requested by the first node. In one example, the uplink channel may be a PUCCH; in another example, it may be a PUSCH; and in yet another example, it may be a channel containing specific uplink control information, such as scheduling requests, channel quality indicators, HARQ ACK / NACK information, etc. Further, this information may also be a list containing resource request information for one or more uplink channels.

In one example, this information includes cell group identification information.

[0288] User configuration information, which includes other configurations required by the user device, includes at least one of the following:

[0289] ■ General configuration information, applicable to all cells configured for user equipment, includes at least one of the following:

[0290] ◆ For media access control configuration information, please refer to the description in step 1-1 above.

[0291] ◆Physical layer configuration information, see the description in step 1-1 above.

[0292] ■ Energy-saving configuration information, which includes the energy-saving configuration of user equipment. In one example, this information is the configuration information for discontinuous DRX reception. Further, this information may include a list containing one or more DRX configuration information entries. For each DRX configuration information entry, it also includes the identification information of the DRX group and information about the cell using that DRX configuration information.

[0293] ■ Configuration information for the scheduling request, which includes the resource configuration information for the scheduling request. In one example, this information includes the scheduling request identification information.

[0294] ■ Configuration information for the advance scheduling group. This information includes details about the advance scheduling group, such as its identifier and the identifier of the cell within that group.

[0295] Through the above process, multiple serving cells can be configured for a user equipment (UE), and these cells may belong to different nodes, but the UE is unaware that these cells belong to different nodes. The beneficial effects of this process include: 1) reducing the signaling overhead required for configuring UEs with multiple serving cells; 2) reducing the processing load on the UE side (e.g., eliminating the need to establish multiple MAC entities); and 3) allowing the UE to dynamically change the required configuration information based on the distribution of different data flows across different nodes, thereby effectively transmitting data, reducing resource waste, and ensuring the QoS requirements of the UE.

[0296] In the above process, the first request message and the first response message can be signaling messages between base stations, such as cross-node / base station fusion request messages and cross-node / base station fusion response messages, or other messages. The first configuration message can be an RRC message, such as an RRC reconfiguration message, or other messages.

[0297] The above process is illustrated using signaling interaction between the first node and the second node. In another example, the process of steps 1-1 and 1-2 above can also occur between the first node and the third node (e.g., by replacing the second node in steps 1-1 and 1-2 with the third node), or between the second node and the fourth node (e.g., by replacing the first node and the second node in steps 1-1 and 1-2 with the second node and the fourth node, respectively).

[0298] Based on the above configuration process, users are configured with serving cells belonging to different nodes. These serving cells are configured to user equipment using carrier aggregation. In one example, this configuration will assign a primary cell (PCell) and at least one secondary cell (SCell) to the user equipment. To improve the flexibility of using these serving cells, this invention also proposes a method for dynamically changing the user equipment configuration. This method includes the following aspects:

[0299] Aspect 1: Communities that dynamically change the service user equipment

[0300] When a user equipment is configured with multiple serving cells, some serving cells can be dynamically activated or deactivated based on the amount of user data. This reduces the energy consumption of the user equipment and improves the utilization efficiency of spectrum resources. The method includes the following steps: Figure 7 As shown:

[0301] Step 2-1: A network node (such as a first node or a second node) sends a first indication message to the user equipment. This message indicates the activation or deactivation of a serving cell. In one example, the activated or deactivated cell belongs to a cell belonging to a node other than the network node. The message includes at least one of the following information:

[0302] ■ Cell indication information. In one example, the cell indicated by this information is a secondary cell; in another example, the cell indicated by this information is a cell containing an uplink channel; in yet another example, the cell identified by this information is a cell without an uplink channel; in yet another example, the cell identified by this information is a PUCCH cell; and in yet another example, the cell identified by this information is a non-PUCCH cell. This cell indication information indicates whether the cell is active or deactivated. The aforementioned uplink channel can be a channel containing specific uplink control information, examples of which include scheduling requests, channel quality indications, HARQ ACK / NACK information, etc. This information includes at least one of the following:

[0303] ■Community signage information

[0304] ■ The index information of the cell, which indicates a cell

[0305] ■ Bitmap information, which indicates which cells need to be activated or deactivated. Each bit in this bitmap represents a cell.

[0306] ■ Activation indication information, which is used to indicate whether to activate or deactivate the cell indicated by the above "cell indication information". In one example, when activating or deactivating multiple cells, this information may contain a bitmap information, where each bit of the bitmap represents a cell, and the value of each bit indicates whether the cell is activated or deactivated (e.g., "1" indicates activation and "0" indicates deactivation, or "1" indicates deactivation and "0" indicates activation).

[0307] ■ First data stream configuration indication information, which indicates the configuration of the data stream. In one example, this information may be the identification information of the data stream, or the identification information of the data stream configuration. The user equipment will determine the configuration it uses based on this information, such as the configuration of resources (e.g., uplink channel resources) indicated by the "resource indication information" in steps 1-3 above.

[0308] ■ Access information, which indicates the configuration information required to access the cell. Based on this information, the user equipment can access the cell indicated by the activated "cell indication information" mentioned above. Based on this information, the user equipment obtains the information required to access the activated cell (such as a secondary cell), reducing cell access latency. This information includes at least one of the following:

[0309] ■ Random access information, which includes information required by the user equipment for random access, such as the index information of the random access preamble and the indication information of the random access timing.

[0310] ■ Timing advance information, which indicates the timing advance used by the user equipment when accessing the activated cell.

[0311] Step 2-2: User Equipment activates or deactivates the serving cell. If step 2-1 indicates deactivation of the cell, the user equipment can stop data transmission on the deactivated cell. If step 2-2 indicates activation of the cell, the user equipment can access the activated cell based on the information in the first indication information. In one example, the user equipment can perform a random access procedure on the activated cell based on the information in the access information, or directly use the timing advance information in the access information to perform data transmission on the activated cell.

[0312] When the node that decides to activate or deactivate a cell is different from the node where the activated or deactivated cell is located, the above process also includes the following steps:

[0313] Step 2-3: Optional (may occur after step 2-1 or step 2-2), the first node sends a first notification message to the second node, or the second node sends a first notification message to the first node. This message provides information about activated or deactivated cells and includes at least one of the following:

[0314] ■Identification information for activated or deactivated cells

[0315] ■ Data stream configuration indication information, which indicates the configuration of the data stream. In one example, this information can be the identification information of the data stream or the identification information of the data stream configuration. The receiving node uses this information to determine the configuration it uses, such as the configuration of resources (e.g., uplink channel resources) indicated by the "resource indication information" in steps 1-3 above.

[0316] Part Two: Dynamically changing the configuration of uplink channel resources for user equipment

[0317] When a user equipment (UE) is configured to serve multiple cells belonging to different nodes, the configuration of uplink channel resources used by the UE will change depending on the amount of user data served by each node. Therefore, the network side should dynamically change the uplink channel resource configuration based on the distribution of data flows across different nodes. This approach allows for the rational allocation of uplink resources across different nodes, reduces resource waste, and improves the efficiency of each node in serving different data flows. The method includes the following steps: Figure 8 As shown:

[0318] Step 3-1: A network node (such as the first node or the second node) sends a second indication message to the user equipment. This message is used to indicate the configuration of the user equipment's data flow and includes at least one of the following information:

[0319] ■ Second data stream configuration indication information. This information indicates the configuration of the data stream. In one example, this information can be the identification information of the data stream or the identification information of the data stream configuration. The user equipment will determine the configuration it uses based on this information, such as the configuration of resources (e.g., uplink channel resources) indicated by the "resource indication information" in steps 1-3 above, and then determine the uplink channel resources.

[0320] ■ First indication information of uplink channel resources, which includes at least one of the following:

[0321] ■ Fourth cell identification information, which identifies the cell that contains uplink channel resources.

[0322] ■ Associated cell indication information, which indicates cells that do not contain uplink channel resources and are associated with the aforementioned "fourth cell identification information". In one example, this indication information includes cell identification information; in another example, it includes cell index information, which can be used to indicate the cell identification information; in yet another example, this indication information can be a bitmap information, where each bit represents a cell, and the bit value indicates whether it is associated with the aforementioned "cell identification information" (e.g., "1" indicates association, "0" indicates no association, or "0" indicates association, "1" indicates no association).

[0323] ■ Associated uplink channel resource first indication information, which includes at least one of the following:

[0324] ■ Fifth cell identification information, which identifies cells that do not contain uplink channel resources.

[0325] ■ Associated cell indication information, which indicates the cell containing uplink channel resources associated with the aforementioned "Fifth Cell Identification Information". In one example, this indication information includes the cell's identification information; in another example, it includes the cell's index information, which can be used to indicate the cell's identification information; in yet another example, this indication information can be a bitmap information, where each bit represents a cell, and the bit value indicates whether it is associated with the aforementioned "Cell Identification Information" (e.g., "1" indicates association, "0" indicates no association, or "0" indicates association, "1" indicates no association).

[0326] Step 3-2: The user equipment determines the configuration of uplink channel resources. This uplink channel can be a channel containing specific uplink control information, such as scheduling requests, channel quality indicators, HARQ ACK / NACK information, etc. Specifically, this step includes:

[0327] ■ Determine the configuration of uplink channel resources for cells containing uplink channels.

[0328] If the "data stream identification information" or "data stream configuration identification information" indicated in step 3-1 is the same as the "associate data stream information" contained in the "uplink channel resource indication information" in step 1-3 above, and the cell containing uplink channel resources is in an active state, then the user equipment determines the uplink channel resources based on other information (such as start position indication information, length indication information, end position indication information, frequency domain indication information, and time division multiplexing form indication information) contained in the "uplink channel resource indication information" in step 1-3 above. Figure 9 The different uplink channel resource allocation methods corresponding to different "data stream configuration identification information" are given. That is, when the data stream configuration identification information = 2, cell 1 is allocated more uplink channel resources, while when the data stream configuration identification information = 1, cell 1 is allocated fewer uplink channel resources.

[0329] ■ Determine the uplink channel resources associated with cells that do not contain uplink channels.

[0330] For a cell (first cell) configured for a user equipment (UE) that does not contain an uplink channel, the UE needs to determine the cell (second cell) associated with the first cell that contains an uplink channel. In one example, the UE can determine the second cell based on the "serving cell configuration information" in steps 1-3 above, and determine the cell associated with the second cell that does not contain uplink channel resources based on the "information of the third associated cell" in the "uplink channel resource indication information," thus determining whether the first cell is associated with the second cell. In another example, the UE can determine the second cell associated with the first cell based on the "identification information of the fourth associated cell" in the "associated uplink channel resource indication information" in steps 1-3. In yet another example, the UE can determine the associated first and second cells based on the "uplink channel resource indication information" or "associated uplink channel resource indication information" in step 3-1. Further, optionally, if there are multiple second cells associated with the first cell determined by the above method, and each second cell is active, the UE can determine the cell with the highest priority as the second cell based on the "priority indication information" in steps 1-3. After the second cell is determined, if the "data stream identification information" or "data stream configuration identification information" indicated in step 3-1 above is the same as the "associate data stream information" contained in the "uplink channel resource indication information" in step 1-3 above, and the cell containing uplink channel resources (the second cell) is in an active state, then the user equipment determines the uplink channel resources of the second cell associated with the first cell based on other information (such as start position indication information, length indication information, end position indication information, frequency domain indication information, and time division multiplexing form indication information) contained in the "uplink channel resource indication information" in step 1-3 above. Figure 10 An example is given: Cell 1 does not contain an uplink channel, while Cell 2 does. To transmit the uplink control information required by Cell 1, it needs to be sent through the uplink channel of Cell 2. Furthermore, the resource allocation of the uplink channel in Cell 2 varies depending on the data stream allocation method. For example, when the configuration identifier of the data stream is 2, Cell 2 is allocated more uplink channel resources, while when the configuration identifier of the data stream is 1, Cell 2 is allocated fewer uplink channel resources.

[0331] After deciding to change the data flow configuration, network nodes also need to exchange the latest data flow configuration information. The above process also includes the following steps:

[0332] Step 3-3: Optional (may occur after Step 3-1 or Step 3-2), the first node sends a second notification message to the second node, or the second node sends a second notification message to the first node. This message provides data stream configuration indication information, which indicates the configuration of the data stream. In one example, this information may be the identification information of the data stream, or the identification information of the data stream configuration. The receiving node determines the configuration it uses based on this information, such as the configuration of resources (e.g., uplink channel resources) indicated by the "resource indication information" in Step 1-3 above.

[0333] The first and second instruction messages mentioned above can be messages containing MAC control elements, RRC messages, physical layer messages, or other types of messages.

[0334] Part Three: User equipment dynamically selects different cells for data transmission.

[0335] When a user equipment (UE) is configured with multiple serving cells, to reduce energy consumption, the UE can transmit data across more cells only when the data volume is large, and use fewer cells for data transmission when the data volume is small. This reduces the UE's energy consumption. To achieve this, the UE can determine whether to initiate data transmission on other cells based on the configuration information in steps 1-3. Specifically, the UE will perform the following actions:

[0336] ■ To determine whether the amount of specific data transmitted by the user equipment exceeds the configured "threshold indication information", the following methods can be used:

[0337] ■Method 1: Determine the action based on the total amount of data transmitted. If the total amount of data exceeds a threshold, then proceed with the subsequent actions.

[0338] ■Method 2: Determining based on the amount of specific data, which can be data indicated by at least one of the following:

[0339] ◆Data with specific identification information, such as the data indicated by the "data identification information" in the "data threshold information" in steps 1-3 above.

[0340] ◆Data served by a specific cell, such as the data served by the "Cell Identification Information" in the "Data Threshold Information" section of steps 1-3 above.

[0341] ◆Data from user equipment under a specific data flow configuration, such as the data from user equipment under the "data flow identification information" or "data flow configuration identification information" in steps 1-3 above.

[0342] ■ When the amount of specific data transmitted by the user equipment exceeds the configured "threshold indication information", the user equipment will transmit data using the cell indicated by the "indication information of the enabled cell" or "indication information of the enabled cell group" in steps 1-3 above.
