Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a configuration method and apparatus. Background Art

[0002] In a dual-connectivity (DC), such as a multi-radio dual-connectivity (MR-DC) scenario, a terminal can communicate with multiple access network devices. For example, the terminal can communicate with a master cell group (MCG) managed by a master node (MN) and a secondary cell group (SCG) managed by a secondary node (SN) simultaneously. Further, when the data transmitted by the terminal on the SCG side is relatively small or there is no data transmission, or the required data rate is relatively low, the terminal will temporarily deactivate or suspend the SCG to reduce the power consumption of the terminal. When the data transmitted by the terminal on the SCG side is relatively active, or the required data rate is relatively high, the terminal will activate the SCG to ensure smooth data transmission.

[0003] Currently, the network side can activate or deactivate cells in a cell group through a MAC CE. However, the design of the MAC CE is not flexible enough, resulting in the MAC CE not being able to meet some management requirements of the network side for cells in the cell group. For example, when the primary secondary cell (PSCell) in the secondary cell group is in an active state, the terminal can receive the MAC CE sent by the secondary node and activate / deactivate the cells in the SCG according to the MAC CE sent by the secondary node. However, when the SCG of the terminal is in a deactivated state, since the terminal stops listening to the physical downlink control channel (PDCCH) sent by the secondary node, the terminal cannot receive the MAC CE sent by the secondary node carrying the SCG activation indication, and thus the terminal cannot activate the SCG. Summary of the Invention

[0004] This application provides a configuration method and apparatus for meeting the requirements of the network side to manage cells in a cell group using a MAC CE in some communication scenarios (such as the case where the SCG is deactivated).

[0005] In a first aspect, a configuration method is provided, including: a terminal receives a medium access control (MAC) control element (CE) sent by a first node, where the MAC CE is used to activate or deactivate one or more cells in a cell group managed by a second node, and the first node is different from the second node; the terminal activates or deactivates one or more cells in the cell group managed by the second node according to the MAC CE.

[0006] Based on the above technical solution, the first node sends a MAC CE to the terminal, so that the terminal can activate / deactivate cells in the cell group managed by the second node according to the MAC CE sent by the first node. Compared with the prior art where a MAC CE sent by a node can only be used to activate / deactivate cells in the cell group managed by the node, the MAC CE provided in the embodiments of this application enables a node to instruct the terminal to activate / deactivate cells in the cell group managed by another node, improving the flexibility of the MAC CE, thereby meeting the usage requirements of the network side for the MAC CE in some special scenarios. For example, in the scenario of SCG deactivation, the technical solution provided in this application ensures that the master node can use the MAC CE to instruct the terminal to activate cells in the SCG, enabling the network side to effectively manage the SCG.

[0007] In a possible design, the first node is a master node, the second node is a secondary node, and the cell group managed by the second node is an SCG.

[0008] In a possible design, the first node is a secondary node, the second node is a master node, and the cell group managed by the second node is an MCG.

[0009] In a possible design, when all cells in the SCG are in the deactivated state, the MAC CE is at least used to activate the primary and secondary cells.

[0010] In a possible design, the MAC CE is further used to activate at least one secondary cell. Wherein, the secondary cell can be a secondary cell in the MCG or a secondary cell in the SCG.

[0011] In a possible design, the MAC CE includes first indication information, and the first indication information is a reserved bit with a first value in the payload of the MAC CE.

[0012] In a possible design, when the master cell group (MCG) includes a primary cell and M secondary cells, and the secondary cell group (SCG) includes a primary secondary cell and N - 1 secondary cells, the payload of the MAC CE includes: M first bits and N second bits, where M is a non - negative integer and N is a positive integer. Among them, the M first bits correspond one - to - one with the M secondary cells in the MCG; when the value of the first bit is the second value, the first bit is used to indicate activating the secondary cell corresponding to the first bit; or, when the value of the first bit is the third value, the first bit is used to indicate de - activating the secondary cell corresponding to the first bit. The N second bits correspond one - to - one with the N cells in the SCG; when the value of the second bit is the second value, the second bit is used to indicate activating the cell corresponding to the second bit; or, when the value of the second bit is the third value, the second bit is used to indicate de - activating the cell corresponding to the second bit.

[0013] In a possible design, the sub - header of the MAC CE contains a logical channel identity (LCID) with a value of 57 or 58. Based on this design, the MAC CE provided in this application multiplexes the MAC CE used for SCell activation / de - activation in the prior art.

[0014] In a possible design, the payload of the MAC CE includes one or more third bits, and each third bit corresponds to an SCG; when the value of the third bit is the fourth value, the third bit is used to indicate activating the SCG corresponding to the third bit; or, when the value of the third bit is the fifth value, the third bit is used to indicate de - activating the SCG corresponding to the third bit.

[0015] In a possible design, when the sub - header of the MAC CE contains an LCID with a value of the second preset value, the MAC CE is used to indicate de - activating the SCG; or, when the sub - header of the MAC CE contains an LCID with a value of the third preset value, the MAC CE is used to indicate activating the SCG. Optionally, based on this design, the MAC CE does not include a payload. Based on this design, signaling overhead can be reduced.

[0016] In a possible design, the configuration method further includes: the terminal sends second indication information to the first node or the second node, where the second indication information is used to indicate that the terminal has the ability to activate or deactivate a cell in the cell group managed by the second node according to the MAC CE sent by the first node; or, the second indication information is used to indicate that the terminal does not have the ability to activate or deactivate a cell in the cell group managed by the second node according to the MAC CE sent by the first node. Based on this design, the network side can, according to the second indication information, know whether the terminal has the ability to activate or deactivate a cell in the cell group managed by the second node according to the MAC CE sent by the first node.

[0017] In a possible design, the configuration method further includes: the terminal receives first request information sent by the first node, where the first request information is used to request the terminal to report the second indication information.

[0018] In a second aspect, a configuration method is provided, including: the first node generates a MAC CE, where the MAC CE is used to activate or deactivate one or more cells in the cell group managed by the second node, and the first node is different from the second node; the first node sends the MAC CE to the terminal.

[0019] Based on the above technical solution, the first node sends a MAC CE to the terminal, so that the terminal can activate / deactivate a cell in the cell group managed by the second node according to the MAC CE sent by the first node. Compared with the prior art where the MAC CE sent by one node can only be used to activate / deactivate a cell in the cell group managed by that node, the MAC CE provided in the embodiments of the present application enables one node to instruct the terminal to activate / deactivate a cell in the cell group managed by another node, improving the flexibility of the MAC CE, thereby meeting the usage requirements of the network side for the MAC CE in some special scenarios. For example, in the scenario of SCG deactivation, the technical solution provided in the present application ensures that the master node can use the MAC CE to instruct the terminal to activate a cell in the SCG, enabling the network side to effectively manage the SCG.

[0025] In a possible design, the MAC CE includes first indication information, and the first indication information is the reserved bits with the first value in the payload of the MAC CE.

[0026] In a possible design, when the master cell group (MCG) includes a primary cell and M secondary cells, and the SCG includes a primary-secondary cell and N - 1 secondary cells, the payload of the MAC CE includes: M first bits and N second bits, where M is a non-negative integer and N is a positive integer; among them, the M first bits correspond one-to-one with the M secondary cells in the MCG; when the value of the first bit is the second value, the first bit is used to indicate activating the secondary cell corresponding to the first bit; or, when the value of the first bit is the third value, the first bit is used to indicate deactivating the secondary cell corresponding to the first bit; the N second bits correspond one-to-one with the N cells in the SCG; when the value of the second bit is the second value, the second bit is used to indicate activating the cell corresponding to the second bit; or, when the value of the second bit is the third value, the second bit is used to indicate deactivating the cell corresponding to the second bit.

[0027] In a possible design, the sub-header of the MAC CE includes an LCID with a value of 57 or 58. Based on this design, the MAC CE provided in this application multiplexes the MAC CE used for SCell activation / deactivation in the prior art.

[0033] Based on the above technical solutions, on the one hand, since the fourth indication information for indicating deactivating the SCG includes non-competitive random access configuration information, the terminal can directly initiate random access according to the non-competitive random access configuration information included in the fourth indication information after receiving the fifth indication information, without waiting for the network side to send the non-competitive random access configuration information, thereby reducing the delay of the terminal initiating random access. On the other hand, compared with the prior art in which the terminal initiates competitive random access to activate cells in the SCG, in the technical solution provided in this application, the terminal activates cells in the SCG by initiating non-competitive random access, avoiding the problem of random access failure caused by conflicts and competition, thus completing random access faster, and then activating cells in the SCG faster.

[0034] In a possible design, the terminal receiving the fourth indication information includes: the terminal receives the fourth indication information sent by the master node; or, the terminal receives the fourth indication information sent by the secondary node.

Any embodiment or design solution described as "exemplary" or "for example" in this application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, using words such as "exemplary" or "for example" is intended to present relevant concepts in a specific way.

[0110] In the description of this application, "indication" can include direct indication and indirect indication, and can also include explicit indication and implicit indication. If the information indicated by a certain piece of information (such as the first indication information described below) is called the information to be indicated, then in the specific implementation process, there are many ways to indicate the information to be indicated. For example, the information to be indicated can be directly indicated, including the information to be indicated itself or the index of the information to be indicated, etc. For another example, the information to be indicated can also be indirectly indicated by indicating other information, where there is an association relationship between the other information and the information to be indicated. For another example, only a part of the information to be indicated can be indicated, while the other parts of the information to be indicated are known or pre-agreed. In addition, the indication of specific information can also be achieved by relying on the arrangement order of each piece of information pre-agreed (such as protocol regulations), so as to reduce the indication overhead to a certain extent.

[0111] To facilitate the understanding of the technical solution of this application, the terms involved in this application will be briefly introduced below.

[0112] 1. Random access

[0113] Random access is the process for a terminal to establish a connection with a network device before entering the connected / active state from the idle / inactive state. The main purpose of random access is to establish uplink synchronization and request the network device to allocate uplink resources to the terminal so that the terminal can perform corresponding data transmission through the uplink resources.

[0114] Random access is divided into a competitive random access process and a non-competitive random access process. Compared with the competitive random access process, the biggest difference in the non-competitive random access process is that the preamble used for random access is allocated by the network side instead of being generated by the terminal side, which reduces the competition and conflict resolution process.

[0115] According to the number of steps required to complete the random access process, the non-competitive random access process can be divided into a two-step non-competitive random access and a four-step non-competitive random access.

[0116] 2. Active cell

[0117] In the embodiments of the present application, an "active cell" can be understood as "putting the cell in an active state (activation)" or "resuming the cell".

[0118] When a cell is in an active state, the terminal activating the cell is equivalent to the terminal keeping the cell in the active state. When a cell is in an inactive state, the terminal activating the cell is equivalent to the terminal switching the cell from the deactivated state to the active state.

[0119] 3. Deactive cell

[0120] In the embodiments of the present application, a "deactive cell" can be understood as "putting the cell in a deactivated state (deactivation)" or "suspending the cell".

[0121] When a cell is in an active state, the terminal deactivating the cell is equivalent to the terminal switching the cell from the active state to the deactivated state. When a cell is in a deactivated state, the terminal deactivating the cell is equivalent to the terminal keeping the cell in the deactivated state.

[0122] It should be noted that the terminal deactivating a cell does not mean that the network side "closes" the cell, but rather that the cell pauses receiving / sending data related to this terminal.

[0123] In addition, for a terminal, when the cell is in a deactivated state, the terminal does not need to receive the corresponding PDCCH or physical downlink shared channel (PDSCH) of the cell, cannot send uplink data on the cell, and does not need to perform channel quality indication (CQI) measurement of the cell.

[0124] The configuration method provided by the embodiments of the present application can be applied to Figure 1The communication system shown. As Figure 1 shown, the communication system includes a terminal, a master node (MN), a secondary node (SN), and a core network.

[0125] Among them, the terminal can support Dual Connectivity (DC) and establish wireless connections with both the master node and the secondary node. Thus, the master node and the secondary node can jointly provide data transmission services for the terminal.

[0126] The master node is connected to the core network (CN) through the S1 / NG interface. There is at least a control plane connection between the master node and the core network, and there can also be a user plane connection. The S1 interface includes S1-U / NG-U and S1-C / NG-C. Among them, S1-U / NG-U represents the user plane connection, and S1-C / NG-C represents the control plane connection. The secondary node may or may not have a user plane connection with the core network. When the secondary node does not have a user plane connection with the core network, the data of the terminal can be split by the master node to the secondary node at the packet data convergence protocol (PDCP) layer. This master node can also be referred to as the master base station or the main access network device, and the SN can also be referred to as the secondary base station or the secondary access network device.

[0127] In the dual connectivity scenario, the master node manages a primary cell (PCell). Among them, the primary cell refers to the cell deployed on the primary frequency point and accessed during the initial connection establishment process or the RRC connection re-establishment process initiated by the terminal, or the cell indicated as the primary cell during the handover process.

[0128] Furthermore, in addition to the primary cell, the master node can also manage one or more secondary cells (SCells). The cells that provide services for the terminal under the master node, such as the primary cell and the secondary cells under the master node, can be collectively referred to as the MCG.

[0129] The secondary node manages a primary secondary cell (PSCell). Among them, the primary secondary cell can be the cell accessed during the random access process initiated by the terminal to the secondary node, or the cell on another secondary node where the terminal skips the random access process and initiates data transmission during the secondary node change process, or the cell on the secondary node accessed during the random access process initiated during the synchronous reconfiguration process.

[0130] Further, in addition to the primary and secondary cells, the secondary node may also manage one or more secondary cells. The cells that provide services to the terminal on the secondary node, such as the primary and secondary cells on the secondary node, may be collectively referred to as the SCG.

[0131] For ease of description, in the NR protocol, the primary cell and the primary and secondary cells are collectively referred to as the special cell (SpCell).

[0132] The above-mentioned primary node and secondary node may be collectively referred to as network devices. The network devices include but are not limited to: access points (APs) in a wireless fidelity (WiFi) system, such as home gateways, routers, servers, switches, bridges, etc., evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB, or home Node B, HNB), baseband unit (BBU), wireless relay node, wireless backhaul node, transmission and reception point (TRP or transmission point, TP), etc. It may also be 5G, such as a gNB in a new radio (NR) system, or a transmission point (TRP or TP), one or a group (including multiple antenna panels) of antenna panels of a base station in a 5G system, or it may also be a network node constituting a gNB or a transmission point, such as a baseband unit (BBU), or a DU, a roadside unit (RSU) with base station functions, etc.

[0133] In the embodiments of the present application, the network device may adopt a CU-DU architecture. That is, the network device may be composed of a CU and at least one DU. In this case, some functions of the network device are deployed on the CU, and another part of the functions of the network device are deployed on the DU. The CU and the DU are functionally split according to the protocol stack. As an implementation, the CU is deployed with the radio resource control (RRC) layer, the packet data convergence protocol (PDCP) layer, and the service data adaptation protocol (SDAP) layer in the protocol stack; the DU is deployed with the radio link control (RLC) layer, the media access control (MAC) layer, and the physical layer (PHY) in the protocol stack. Thus, the CU has the processing capabilities of RRC, PDCP, and SDAP. The DU has the processing capabilities of RLC, MAC, and PHY. It can be understood that the above functional split is only an example and does not constitute a limitation on the CU and the DU. That is to say, there may be other ways of functional split between the CU and the DU, which are not elaborated in the embodiments of the present application.

[0134] According to the communication systems supported by the master node and the secondary node respectively, there are various implementation manners for the dual-connectivity network, which are illustrated below.

[0135] As Figure 2 shown, it is a schematic diagram of an LTE-NR dual-connectivity (E-UTRA-NR Dual Connectivity, EN-DC) network. The EN-DC network is the dual-connectivity between a 4G radio access network and 5G NR. The LTE base station (LTE eNB) serves as the MN, and the NR base station (NRgNB) serves as the SN. As Figure 2 shown in (a) therein, there is an S1 interface between the LTE eNB and the evolved packet core network (EPC) of the LTE system, and there is at least a control-plane connection, and there may also be a user-plane connection. As Figure 2 shown in (b) therein, there is an S1-U interface between the NR gNB and the EPC, that is, there can only be a user-plane connection.

[0136] As Figure 3As shown, it is a schematic diagram of an NR-LTE dual connectivity (NR-E-UTRA Dual Connectivity, NE-DC) network. The NE-DC network is a dual connectivity between a 4G radio access network and 5G NR under a 5G core network. The NR base station (gNB) serves as the MN, and the LTE base station (ng-eNB) serves as the SN, and both the MN and the SN are connected to the 5G core network (5th Generation Core Network, 5GC). As Figure 3 shown in (a) of Figure 3 , there is an NG interface between the gNB and the 5GC, which can establish a control plane connection and a user plane connection for the terminal. The ng-eNB sends user plane data to the 5GC through the gNB. As

[0137] shown in (b) of Figure 4 , there is an NG-U interface between the ng-eNB and the 5GC, which only establishes a user plane connection for the terminal, and the ng-eNB directly sends user plane data to the 5GC. Figure 4 shown in (a) of Figure 4 , there is an NG interface between the ng-eNB and the 5GC, which can establish a control plane connection and a user plane connection for the terminal. The gNB sends user plane data to the 5GC through the ng-eNB. As

[0138] In Figures 2 to 4 's dual connectivity network, a user plane connection may not be established between the SN and the core network, but the data is transmitted via the MN. For example, in the downlink direction, the terminal's data first reaches the MN, and the MN splits the terminal's data to the SN at the PDCP layer. The form of the split data is, for example, a PDCP protocol data unit (Protocol Data Unit, PDU).

[0139] It can be understood that the communication method provided in the embodiments of the present application can be adapted to the dual connection of traditional LTE, and can also be applied to the EN-DC network, NE-DC network, or NGEN-DC network of the 5G system. It can also be adapted to the NR-NR dual connection (NR-NR Dual Connectivity, NR-DC) of the 5G core network and other future DC architectures. The embodiments of the present application do not limit the specific architecture of the dual connection network adapted to this communication method. Here, only Figures 2 - 4 exemplary illustration is given. In the following embodiments, the EN-DC network architecture is taken as an example to illustrate the communication method provided in the embodiments of the present application. A terminal is a device with wireless transceiver functions. The terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it can also be deployed on the water (such as a ship, etc.); it can also be deployed in the air (such as an airplane, balloon, satellite, etc.). The terminal can be a user equipment (UE). Among them, the UE includes a handheld device, a vehicle-mounted device, a wearable device, or a computing device with wireless communication functions. Exemplarily, the UE can be a mobile phone, a tablet computer, or a computer with wireless transceiver functions. The terminal can also be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in remote medical treatment, a wireless terminal in a smart grid, a wireless terminal in a smart city, a wireless terminal in a smart home, and so on. In the embodiments of the present application, the device for implementing the functions of the terminal can be the terminal or a device capable of supporting the terminal to implement such functions, such as a chip system. In the embodiments of the present application, the chip system can be composed of chips or can also include chips and other discrete devices. In the embodiments of the present application, taking the device for implementing the functions of the terminal as the terminal as an example, the technical solutions provided in the embodiments of the present application are described.

[0140] Figure 5 It is a schematic diagram of the hardware structures of the network device and the terminal provided in the embodiments of the present application.

[0141] The terminal includes at least one processor 101 and at least one transceiver 103. Optionally, the terminal may further include an output device 104, an input device 105, and at least one memory 102.

[0142] The processor 101, the memory 102, and the transceiver 103 are connected by a bus. The processor 101 can be a general-purpose central processing unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits for controlling the execution of the program of the solution of this application. The processor 101 can also include multiple CPUs, and the processor 101 can be a single-CPU processor or a multi-CPU processor. The processor here can refer to one or more devices, circuits, or processing cores for processing data (such as computer program instructions).

[0143] The memory 102 can be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or it can also be an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM), or other optical disc storage, optical disc storage (including compact discs, laser discs, optical discs, digital versatile discs, Blu-ray discs, etc.), magnetic disk storage media, or any other medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer. The embodiments of this application do not impose any restrictions on this. The memory 102 can exist independently and be connected to the processor 101 through a bus. The memory 102 can also be integrated with the processor 101. Among them, the memory 102 is used to store the application program code for executing the solution of this application and is controlled by the processor 101 to execute. The processor 101 is used to execute the computer program code stored in the memory 102, thereby implementing the method provided by the embodiments of this application.

[0144] The transceiver 103 can use any device of the transceiver type for communicating with other devices or communication networks, such as Ethernet, radio access network (RAN), wireless local area networks (WLAN), etc. The transceiver 103 includes a transmitter Tx and a receiver Rx.

[0145] The output device 104 communicates with the processor 101 and can display information in various ways. For example, the output device 104 can be a liquid crystal display (LCD), a light emitting diode (LED) display device, a cathode ray tube (CRT) display device, or a projector, etc. The input device 105 communicates with the processor 101 and can receive user input in various ways. For example, the input device 105 can be a mouse, a keyboard, a touch screen device, or a sensing device, etc.

[0146] The network device includes at least one processor 201, at least one memory 202, at least one transceiver 203, and at least one network interface 204. The processor 201, the memory 202, the transceiver 203, and the network interface 204 are connected by a bus. Among them, the network interface 204 is used to connect to the core network device through a link (such as the S1 interface), or to connect to the network interface of other network devices through a wired or wireless link (such as the X2 interface) (not shown in the figure), and the embodiments of the present application do not make specific limitations on this. In addition, the relevant descriptions of the processor 201, the memory 202, and the transceiver 203 can refer to the descriptions of the processor 101, the memory 102, and the transceiver 103 in the terminal, and will not be elaborated here.

[0147] The network architecture and service scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those of ordinary skill in the art know that with the evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0148] The network device can instruct the terminal to activate / deactivate the SCell through the MAC CE carried by the PDCCH. There are two formats for this MAC CE (Format 1 and Format 2 below).

[0149] As Figure 6 shown, the payload of the MAC CE of Format 1 consists of 8 bits. Specifically, the payload of the MAC CE includes 7 cell fields (C-field) and 1 reserved bit. Among them, the reserved bit is generally set to 0. The value of the LCID in the sub-header of the MAC CE of Format 1 is 58.

[0150] As Figure 7As shown, the payload of the MAC CE in format 2 consists of 32 bits. Specifically, the payload of the MAC CE includes 31 C-fields and 1 reserved bit. The value of the LCID in the sub-header of the MAC CE in format 2 is 57.

[0151] For ease of description, the C-fields in the MAC CE can be numbered as C i , where i represents the sequence number of the C-field in the MAC CE. Taking the MAC CE in format 1 as an example, the 7 C-fields can be numbered as C1 to C7 respectively. Taking the MAC CE in format 2 as another example, the 31 C-fields can be numbered as C1 to C 31 .

[0152] In the dual-connectivity scenario, the terminal is configured with a MAC entity corresponding to the MCG and a MAC entity corresponding to the SCG. Among them, the MAC entity corresponding to the MCG is responsible for processing the MAC CE for the communication between the terminal and the master node. The MAC entity corresponding to the SCG is responsible for processing the MAC CE for the communication between the terminal and the secondary node.

[0153] The MAC entity corresponding to the SCG receives the MAC CE for SCell activation / deactivation sent by the secondary node. The MAC entity corresponding to the SCG resolves this MAC CE in the following way: When the MAC entity corresponding to the SCG is configured with a secondary cell of the secondary cell index (SCellIndex) i, the C i field in this MAC CE is used to indicate the activation / deactivation state of the secondary cell of SCellIndex i. Or, when the MAC entity corresponding to the SCG is not configured with a secondary cell of the secondary cell index (SCellIndex) i, the MAC entity corresponding to the SCG will ignore the C i field in the MAC CE. Among them, when the C i field is set to 1, it means that the secondary cell of SCellIndex i will be activated. When the C i field is set to 0, it means that the secondary cell of SCellIndex i will be deactivated.

[0154] That is to say, for the terminal, the MAC CE for SCell activation / deactivation sent by the secondary node can only be used to activate / deactivate the cells in the SCG, but not to activate / deactivate the cells in the MCG.

[0155] The MAC entity corresponding to the MCG receives the MAC CE sent by the master node for SCell activation / deactivation, and the MAC entity corresponding to the MCG parses the MAC CE in the following manner: When the MAC entity corresponding to the MCG configures a secondary cell of secondary cell index (SCellIndex) i, the C i field in this MAC CE is used to indicate the activation / deactivation state of the secondary cell of SCellIndex i. Alternatively, when the MAC entity corresponding to the MCG does not configure a secondary cell of secondary cell index (SCellIndex) i, the MAC entity corresponding to the MCG will ignore the C i field in the MAC CE.

[0156] That is to say, for the terminal, the MAC CE sent by the master node for SCell activation / deactivation can only be used to activate / deactivate the cells in the MCG, rather than the cells in the SCG.

[0157] It can be seen that the above design of the MAC CE is not flexible enough and cannot meet some management requirements of the network side for the SCG and / or MCG. For example, in the scenario of SCG deactivation, the master node cannot send a MAC CE to instruct the terminal to activate the cells in the SCG.

[0158] To solve the above technical problems, an embodiment of the present application provides a configuration method. As Figure 8 shown, the method includes the following steps:

[0159] S101. The first node generates a MAC CE.

[0160] Wherein, the MAC CE is used to activate or deactivate one or more cells in the cell group managed by the second node, and the first node is different from the second node.

[0161] In a possible design, the first node is the master node and the second node is the secondary node. Thus, the cell group managed by the first node is the MCG, and the cell group managed by the second node is the SCG.

[0162] In another possible design, the first node is the secondary node and the second node is the master node. Thus, the cell group managed by the first node is the SCG, and the cell group managed by the second node is the MCG.

[0163] It should be noted that when the PSCell in the SCG switches from the deactivated state to the activated state, the SCell in the SCG is allowed to switch from the deactivated state to the activated state. For this reason, when the first node is the master node and all cells in the SCG are in the deactivated state, the above MAC CE is at least used to activate the PSCell. Further, the above MAC CE can also be used to activate at least one SCell. Wherein, the at least one SCell may include the SCell in the SCG and / or the SCell in the MCG.

[0164] It should be noted that when the PSCell in the SCG switches from the activated state to the deactivated state, all SCells in the SCG switch from the activated state to the deactivated state. For this reason, when the first node is the master node and the PSCell in the SCG is in the activated state, the above MAC CE is used to deactivate the SCG.

[0165] It should be noted that when the PSCell in the SCG is in the activated state, the SCell in the SCG can switch from the activated state to the deactivated state, or can switch from the deactivated state to the activated state. For this reason, when the first node is the master node and the PSCell in the SCG is in the activated state, the MAC CE is used to deactivate one or more SCells in the SCG; or, the MAC CE is used to activate one or more SCells in the SCG.

[0166] S102. The first node sends a MAC CE to the terminal. Correspondingly, the terminal receives the MAC CE sent by the first node.

[0167] When the first node is the master node, the MAC entity corresponding to the MCG of the terminal receives the MAC CE sent by the master node. Or, when the first node is the secondary node, the MAC entity corresponding to the SCG of the terminal receives the MAC CE sent by the secondary node.

[0168] S103. The terminal activates / deactivates one or more cells in the cell group managed by the second node according to the MAC CE.

[0169] The different implementation manners of the MAC CE provided in the embodiments of the present application are described below. Among them, implementation manner 1 is applicable to the scenario where the first node is the master node or the secondary node. Implementation manner 2 is only applicable to the scenario where the first node is the master node.

[0170] Implementation manner 1: The MAC CE includes first indication information, and the first indication information is the reserved bit with a value of the first numerical value in the payload of the MAC CE. Optionally, the first numerical value may be 1.

[0171] Based on Implementation Method 1, when the MCG includes one PCell and M SCell, and the SCG includes one PSCell and N - 1 SCell, the payload of the MAC CE further includes M first bits and N second bits. M is a non - negative integer, and N is a positive integer.

[0172] Among them, the M first bits correspond one - to - one with the M SCell in the MCG. The value of each first bit is used to indicate activation / de - activation of the SCell corresponding to this first bit. For example, when the value of the first bit is the second value, the first bit is used to indicate activation of the SCell corresponding to this first bit. Or, when the value of the first bit is the third value, the first bit is used to indicate de - activation of the SCell corresponding to this first bit. Optionally, the second value can be 1, and the third value can be 0. Or, the second value can be 0, and the third value can be 1.

[0173] In practical applications, the values of the M first bits are determined according to actual requirements (such as the terminal's requirement for network speed). Exemplarily, the values of the M first bits can all be the second value. Or, the values of the M first bits can all be the third value. Or, for some of the M first bits, the value is the second value, and for the other part of the M first bits, the value is the third value.

[0174] The N second bits correspond one - to - one with the N cells in the SCG. The N cells are composed of one PSCell and N - 1 SCell. The value of the second bit is used to indicate activation / de - activation of the cell corresponding to this second bit. For example, when the value of the second bit is the second value, the second bit is used to indicate activation of the cell corresponding to this second bit. Or, when the value of the second bit is the third value, the second bit is used to indicate de - activation of the cell corresponding to this second bit.

[0175] In practical applications, the values of the N second bits are determined according to actual requirements. For example, the values of the N second bits can all be the second value. Or, the values of the N second bits can all be the third value. Or, for some of the N second bits, the value is the second value, and for the other part of the N second bits, the value is the third value.

[0176] In the embodiments of the present application, the correspondence relationship between the bit and the cell, such as the correspondence relationship between the first bit and the secondary cell in the MCG, or the correspondence relationship between the second bit and the cell in the SCG, can be specifically implemented as: the correspondence relationship between the number of the bit and the index of the cell. For example, the bit numbered C i corresponds to the cell with index i, and i can be a non - negative integer.

[0177] Optionally, the network device and the terminal may negotiate in advance or the communication protocol may be predefined in advance: in the sub-header of the MAC CE sent by the first node, the bits corresponding to the cells in the cell group managed by the first node are invalid bits.

[0178] For example, when the first node is the master node, the M first bits in the payload of the MAC CE are invalid bits. In this case, the terminal will ignore the M first bits in the payload of the MAC CE. That is, regardless of the values of the M first bits, the terminal will not change the state of the SCell in the MCG.

[0179] For another example, when the first node is the secondary node, the N second bits in the payload of the MAC CE are invalid bits. In this case, the terminal will ignore the N second bits in the payload of the MAC CE. That is, regardless of the values of the N second bits, the terminal will not change the state of the cell in the SCG.

[0180] Optionally, the network device and the terminal may negotiate in advance or the communication protocol may be predefined in advance: in the sub-header of the MAC CE sent by the first node, the bits corresponding to the cells in the cell group managed by the first node are valid bits.

[0181] For example, when the first node is the master node, the M first bits in the payload of the MAC CE are valid bits. In this case, the terminal will read the M first bits in the payload of the MAC CE and perform corresponding activation / deactivation operations on the SCell in the MCG according to the values of the M first bits.

[0182] For another example, when the first node is the secondary node, the N second bits in the payload of the MAC CE are valid bits. In this case, the terminal will read the N second bits in the payload of the MAC CE and perform corresponding activation / deactivation operations on the cell in the SCG according to the values of the N second bits.

[0183] Optionally, based on Implementation Mode 1, the MAC CE provided in the embodiments of the present application may adopt Figure 6 or Figure 7 the MAC CE for SCell activation / deactivation described therein. In this case, the value of the LCID in the sub-header of the MAC CE provided in the embodiments of the present application is 57 or 58.

[0184] Optionally, based on Implementation Mode 1, the MAC CE provided in the embodiments of the present application may also not adopt Figure 6 or Figure 7The MAC CE for SCell activation / deactivation described therein. In this case, the value of the LCID in the sub-header of the MAC CE provided by the embodiments of the present application is a value other than 57 or 58.

[0185] Implementation method 2: The payload of the MAC CE includes one or more third bits, and each third bit corresponds to an SCG. The value of the third bit is used to indicate activation or deactivation of the SCG corresponding to the third bit. Exemplarily, when the value of the third bit is a fourth value, the third bit is used to indicate activation of the SCG corresponding to the third bit. Or, when the value of the third bit is a fifth value, the third bit is used to indicate deactivation of the SCG corresponding to the third bit.

[0186] Optionally, the fourth value can be 1 and the fifth value can be 0. Or, the fourth value can be 0 and the fifth value can be 1.

[0187] Optionally, when the number of third bits is equal to 1, this third bit corresponds to the SCG currently configured for the terminal. For example, the payload of the MAC CE is 1 byte, and the first bit in the payload (i.e., the above-mentioned third bit) corresponds to the SCG currently configured for the terminal, and the other seven bits are reserved bits. When the value of the first bit is 1, this MAC CE is used to indicate deactivation of the SCG configured for the terminal; when the value of the first bit is 0, this MAC CE is used to indicate activation of the SCG configured for the terminal.

[0188] Optionally, when the number of third bits is greater than 1, each third bit corresponds to an SCG, and it can be specifically implemented as: each third bit corresponds to a cell group identity (cellgroup ID) that is not a sixth value. The cell group identity is configured by RRC signaling sent by a network device (such as a master node or a secondary node). It should be noted that in this implementation, the cell group identity with the value of the sixth value is used to indicate the MCG. Exemplarily, the sixth value can be 0.

[0189] Exemplarily, taking the fourth value as 1 and the fifth value as 0 as an example, assume that the master node configures 3 SCGs for the terminal, and the cell group identities of these 3 SCGs are 1, 2, and 3 respectively. The payload of the MAC CE includes 3 third bits, the third bit #1 corresponds to the cell group identity 1, the third bit #2 corresponds to the cell group identity 2, and the third bit #3 corresponds to the cell group identity 3. The other bits in the payload can be reserved bits. When the value of the third bit #1 is 1, the value of the third bit #2 is 0, and the value of the third bit #3 is 1, this MAC CE is used to indicate that the terminal activates the SCGs with cell group identities 1 and 3 and deactivates the SCG with cell group identity 2.

[0190] In an embodiment of the present application, the sub - header of the MAC CE includes an LCID with a value of a first preset value. Among them, the first preset value can be preset according to conditions such as the provisions of a communication protocol; or, the first preset value is determined through negotiation between a network device and a terminal.

[0191] Optionally, in order to distinguish the MAC CE provided in the above - mentioned implementation method 2 from the MAC CE used for SCell activation / de - activation in the prior art, the first preset value is not 57 or 58.

[0192] Implementation method 3: When the sub - header of the MAC CE includes an LCID with a value of a second preset value, the MAC CE is used to indicate de - activation of the SCG. Or, when the sub - header of the MAC CE includes an LCID with a value of a third preset value, the MAC CE is used to indicate activation of the SCG.

[0193] Based on implementation method 3, the above - mentioned MAC CE is applicable to all SCGs configured by the terminal.

[0194] Among them, the second preset value and the third preset value can be preset according to conditions such as the provisions of a communication protocol; or, the second preset value and the third preset value are determined through negotiation between a network device and a terminal.

[0195] Optionally, in order to distinguish the MAC CE in the above - mentioned implementation method 3 from the MAC CE used for SCell activation / de - activation in the prior art, both the second preset value and the third preset value are not 57 or 58.

[0196] Optionally, based on implementation method 3, the above - mentioned MAC CE may not include a payload to reduce signaling overhead.

[0197] Based on Figure 8 the technical solution shown, the first node sends a MAC CE carrying first indication information to the terminal, so that the terminal can activate / de - activate a cell in a cell group managed by the second node according to the MAC CE sent by the first node, thereby solving the problem in the prior art that a MAC CE sent by one node cannot be used to activate / de - activate a cell in a cell group managed by other nodes. Thus, the technical solution provided by the present application can meet the usage requirements of the network side for MAC CE in some special scenarios. For example, in the scenario of SCG de - activation, the technical solution provided by the present application ensures that the master node can use the MAC CE to indicate the terminal to activate the cell in the SCG.

[0198] As Figure 9 shown, a configuration method provided by an embodiment of the present application includes the following steps:

[0199] S201. The terminal sends second indication information to the network device. Correspondingly, the network device receives the second indication information sent by the terminal.

[0200] Among them, the network device can be a master node or a secondary node.

[0201] In the embodiments of the present application, the second indication information is used to indicate that the terminal has cross-CG capability. Or, the second indication information is used to indicate that the terminal does not have cross-CG capability.

[0202] Optionally, the cross-CG capability means that the terminal can activate or deactivate the cells in the cell group managed by the second node according to the MAC CE sent by the first node, or in other words, the terminal supports activating or deactivating the cells in the cell group managed by the second node according to the MAC CE sent by the first node.

[0203] In one implementation, the first node is the master node and the second node is the secondary node. The cross-CG capability means that the terminal supports activating / deactivating the SCG according to the MAC CE sent by the master node.

[0204] Optionally, the second indication information can adopt any one of the following designs:

[0205] Design 1. When the second indication information contains the first cell, the second indication information is used to indicate that the terminal has cross-CG capability. When the second indication information does not contain the first cell, the second indication information is used to indicate that the terminal does not have cross-CG capability.

[0206] Exemplarily, based on Design 1, the first cell can be in the following format:

[0207] IE: crossCG ENUMERATED{true}OPTIONAL

[0208] Among them, crossCG is the name of the first cell, and the supported enumerated value of the first cell is "true". OPTIONAL is used to indicate that this first cell is optional.

[0209] Design 2. When the second indication information contains the first cell with a value of the first enumerated value, the second indication information is used to indicate having cross-CG capability. When the second indication information contains the first cell with a value of the second enumerated value, the second indication information is used to indicate that the terminal does not have cross-CG capability.

[0210] Exemplarily, based on Design 2, the first cell can be in the following format:

[0211] IE: crossCG ENUMERATED{true, false}MANDATORY

[0212] Among them, crossCG is the name of the first cell, and the enumerated values supported by the first cell are "true" and "false". Among them, "true" is the first enumerated value, and "false" is the second enumerated value. MANDATORY indicates that the first cell is mandatory.

[0213] Optionally, the second indication information can reuse the signaling in the existing process to save signaling overhead. Of course, the second indication information can also not reuse the signaling in the existing process, and the embodiments of the present application are not limited thereto.

[0214] As an implementation manner, the terminal can actively send the second indication information to the network device. For example, the terminal can actively send the second indication information to the network device after completing the random access process or after completing the cell handover.

[0215] As another implementation manner, the terminal can passively send the second indication information to the network device. For example, the terminal receives the first request information sent by the network device, and the first request information is used to instruct the terminal to report the second indication information. Then, the terminal sends the second indication information to the network device.

[0216] Optionally, when the network device is the master node, after the master node receives the second indication information sent by the terminal, the master node can send the second indication information of the terminal to the secondary node, so that the secondary node can determine whether the terminal has the cross-CG capability.

[0217] Optionally, when the network device is the secondary node, after the secondary node receives the second indication information sent by the terminal, the secondary node can send the second indication information of the terminal to the master node, so that the master node can determine whether the terminal has the cross-CG capability.

[0218] S202. The network device determines whether the terminal has the cross-CG capability according to the second indication information.

[0219] In this way, when the second indication information is used to indicate that the terminal does not have the cross-CG capability, the network device will not use Figure 8 the MAC CE provided in the shown embodiment. When the second indication information is used to indicate that the terminal has the cross-CG capability, the network device can execute Figure 8 steps S101 and S102 in Figure 8 and the terminal can execute

[0220] As Figure 10 shown, a configuration method provided by an embodiment of the present application includes the following steps:

[0221] S301. The first node sends the third indication information to the terminal. Correspondingly, the terminal receives the third indication information sent by the first node.

[0222] Among them, the first node is the primary node or the secondary node.

[0223] The third indication information is used to indicate that the first node has the ability to send the target MAC CE. Alternatively, the third indication information is used to indicate that the first node does not have the ability to send the target MAC CE. The target MAC CE can be Figure 8 the MAC CE adopting implementation method 1, implementation method 2 or implementation method 3 in the illustrated embodiment.

[0224] Optionally, the third indication information can adopt any one of the following designs:

[0225] Design 1: When the third indication information includes the second cell, the third indication information is used to indicate that the first node has the ability of the target MAC CE. When the third indication information does not include the second cell, the third indication information is used to indicate that the first node does not have the ability to send the MAC CE carrying the target.

[0226] Design 2: When the third indication information includes the second cell with a value of the third enumerated value, the third indication information is used to indicate that the first node has the ability to send the MAC CE carrying the target. When the third indication information includes the second cell with a value of the fourth enumerated value, the third indication information is used to indicate that the first node does not have the ability to send the target MAC CE.

[0227] Exemplarily, the third enumerated value can be "true", and the fourth enumerated value can be "false".

[0228] Optionally, the third indication information can reuse the signaling in the existing process, such as the signaling in the initial access process, to save signaling overhead. Of course, the third indication information can also not reuse the signaling in the existing process, and the embodiments of the present application are not limited thereto.

[0229] As a possible implementation method, the first node sends the third indication information to the terminal in a broadcast manner.

[0230] As another possible implementation method, the first node sends RRC signaling to the terminal, and the RRC signaling includes the third indication information.

[0231] S302. The terminal determines whether the first node has the ability to send the target MAC CE according to the third indication information.

[0232] In this way, when the third indication information is used to indicate that the first node does not have the ability to send the target MAC CE, the first node will not use Figure 8 the MAC CE provided by the illustrated embodiment (i.e., the target MAC CE).

[0233] When there is third indication information, the first node may execute Figure 8 steps S101 and S102 in Figure 8 , and the terminal may execute Figure 8 step S103 in

[0234] That is, the terminal may parse the target MAC CE according to the method introduced in the embodiment shown in

[0235] When the first node does not have the ability to send a MAC CE carrying the first indication information, the terminal parses the MAC CE for SCell activation / deactivation according to the method in the prior art.

[0236] In the prior art, when the SCG of the terminal is in a deactivated state and the terminal receives an instruction to activate the SCG, the terminal initiates contention-based random access to the secondary node, so as to achieve uplink synchronization between the terminal and the secondary node, and at the same time the terminal obtains corresponding uplink resources.

[0237] However, in the contention-based random access process, since the preamble used by the terminal may be the same as the preambles used by other terminals, the random access process of the terminal fails due to conflicts, and further the activation of the SCG by the terminal fails.

[0237] To solve this technical problem, the present application provides a configuration method, and its specific implementation may refer to Figure 11 or Figure 12 .

[0238] As Figure 11 shown, the configuration method includes the following steps:

[0239] S401. The terminal receives fourth indication information.

[0240] Among them, the fourth indication information is used to indicate deactivation of the SCG. The fourth indication information includes contention-free random access configuration information.

[0241] Optionally, the contention-free random access configuration information includes: a dedicated preamble, a dedicated random access configuration parameter (RACH-ConfigDedicated), etc.

[0242] In the embodiments of the present application, the contention-free random access configuration information includes: two-step contention-free random access configuration information and / or four-step contention-free random access configuration information.

[0243] Optionally, the fourth indication information may be carried in an RRC signaling, downlink control information (DCI) or a MAC CE.

[0244] As a possible implementation, the terminal receives the fourth indication information sent by the master node.

[0245] It should be noted that the master node can obtain non-competitive random access configuration information from the secondary node. Exemplarily, it can be that the non-competitive random access configuration is carried in the message indicating data inactivity sent by the secondary station to the master station, or it can be that the non-competitive random access configuration is carried in the SN Modification Required message sent by the secondary station to the master station.

[0246] Optionally, the above message indicating data inactivity can be an Activity Notification message, and the Activity Notification message carries a cell for indicating data activity, and the value of this cell is "inactive".

[0247] As another possible implementation, the terminal receives the fourth indication information sent by the secondary node.

[0248] S402. The master node sends the fifth indication information to the terminal. Correspondingly, the terminal receives the fifth indication information sent by the master node.

[0249] Among them, the fifth indication information is at least used to indicate the activation of the PSCell in the SCG. Optionally, the fifth indication information is also used to indicate the activation of one or more SCell in the SCG.

[0250] Optionally, the fifth indication information can be carried in the RRC signaling, DCI or MAC CE.

[0251] S403. The terminal initiates a random access to the secondary node according to the non-competitive random access configuration information.

[0252] It can be understood that if the fourth indication information only contains two-step non-competitive random access configuration information, the terminal initiates a two-step non-competitive random access to the secondary node. If the fourth indication information only contains four-step non-competitive random access configuration information, the terminal initiates a four-step non-competitive random access to the secondary node. If the fourth indication information contains two-step non-competitive random access configuration information and four-step non-competitive random access configuration information, the terminal can initiate a two-step non-competitive random access or a four-step non-competitive random access according to its actual situation.

[0253] Based Figure 11In the technical solution shown, on the one hand, since the fourth indication information for indicating the deactivation of the SCG includes non-competitive random access configuration information, the terminal can directly initiate random access according to the non-competitive random access configuration information included in the fourth indication information after receiving the fifth indication information, without waiting for the network side to send the non-competitive random access configuration information, thereby reducing the latency of the terminal initiating random access. On the other hand, compared with the prior art where the terminal initiates competitive random access to activate the cell in the SCG, in the technical solution provided in this application, the terminal activates the cell in the SCG by initiating non-competitive random access, avoiding the problem of random access failure caused by conflicts and competition, thus completing random access faster, and then activating the cell in the SCG faster.

[0254] As Figure 12 shown, a configuration method provided by an embodiment of this application includes the following steps:

[0255] S501. The master node sends the fifth indication information to the terminal. Correspondingly, the terminal receives the fifth indication information sent by the master node.

[0256] Among them, the fifth indication information is at least used to indicate the activation of the PSCell in the SCG. Optionally, the fifth indication information is further used to indicate the activation of one or more SCell in the SCG.

[0257] Optionally, the fifth indication information can be carried in RRC signaling, DCI, or MAC CE.

[0258] In the embodiment of this application, the fifth indication information includes non-competitive random access configuration information. Among them, the non-competitive random access configuration information includes: two-step non-competitive random access configuration information and / or four-step non-competitive random access configuration information.

[0259] It should be noted that the master node can obtain the non-competitive random access configuration information from the secondary node.

[0260] S502. The terminal initiates random access to the secondary node according to the non-competitive random access configuration information.

[0261] It can be understood that if the fifth indication information only includes two-step non-competition-based random access configuration information, the terminal initiates two-step non-competition-based random access to the secondary node. If the fifth indication information only includes four-step non-competition-based random access configuration information, the terminal initiates four-step non-competition-based random access to the secondary node. If the fifth indication information includes two-step non-competition-based random access configuration information and four-step non-competition-based random access configuration information, the terminal can initiate two-step non-competition-based random access or four-step non-competition-based random access according to its actual situation.

[0262] based on Figure 12 In the technical solution shown, on the one hand, since the fifth indication information includes non-competition-based random access configuration information, the terminal can directly initiate random access according to the non-competition-based random access configuration information included in the fifth indication information after receiving the fifth indication information, without waiting for the network side to send down the non-competition-based random access configuration information, thereby reducing the delay of the terminal initiating random access. On the other hand, compared with the prior art in which the terminal initiates contention-based random access to activate the cell in the SCG, the technical solution provided by the present application activates the cell in the SCG by initiating non-competition-based random access, thereby avoiding the problem of random access failure caused by conflict and contention, thereby completing random access faster, and then activating the cell in the SCG faster.

[0263] like Figure 13 As shown, when the secondary node adopts the CU-DU architecture, the CU of the secondary node obtains the non-contention-based random access configuration information, including the following steps:

[0264] S601: The CU of the secondary node sends second request information to the DU of the secondary node. Correspondingly, the DU of the secondary node receives the second request information sent by the CU of the secondary node.

[0265] The second request information is used to request non-contention-based random access configuration information.

[0266] Optionally, the second request information may be carried in existing signaling, such as a UE context modification request message.

[0267] As a possible implementation manner, when a preset condition is met, the CU of the secondary node sends second request information to the DU of the secondary node.

[0268] Exemplarily, the preset condition may be any one of the following:

[0269] Condition 1: The CU of the secondary node receives the indication information sent by the primary node for activating the SCG.

[0270] Condition 2: The CU of the secondary node determines to activate the SCG.

[0271] Condition 3: The CU of the secondary node receives the indication information sent by the primary node for deactivating the SCG.

[0272] Condition 4: The CU of the secondary node determines to deactivate the SCG.

[0273] Optionally, based on the above Condition 1 or Condition 2, the second request message may include the indication information for activating the SCG.

[0274] Optionally, based on the above Condition 3 or Condition 4, the second request message may include the indication information for deactivating the SCG.

[0275] S602: The DU of the secondary node sends the second response message to the CU of the secondary node. Correspondingly, the CU of the secondary node receives the second response message sent by the DU of the secondary node.

[0276] Wherein, the second response message is used to respond to the second request message. The second response message includes the non-competitive random access configuration information. The non-competitive random access configuration information includes: two-step non-competitive random access configuration information and / or four-step non-competitive random access configuration information.

[0277] Optionally, the second response message may be carried in an existing signaling, such as a UE context modification response message.

[0278] Based on Figure 13 the technical solution shown, when the secondary node adopts a CU-DU architecture, the CU of the secondary node can obtain the non-competitive random access configuration information from the DU of the secondary node.

[0279] Optionally, after the CU of the secondary node obtains the non-competitive random access configuration information, the CU of the secondary node may send the non-competitive random access configuration information to the primary node. In this way, the primary node can execute Figure 11 step S401 in Figure 12 or

[0280] step S501 in Figure 11 Or, after the CU of the secondary node obtains the non-competitive random access configuration information, the CU of the secondary node may execute
