Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a communication method and a communication device. Background Technology

[0002] With the development of communication technology, new types of terminals will gradually become more common, and a user may own multiple terminals simultaneously. However, due to limitations such as cost, power consumption, and industrial design, the hardware parameters of a single terminal, such as the number of antennas, maximum transmit power, and supported bandwidth, are often restricted. Therefore, it is difficult to improve the communication performance of a terminal by enhancing the hardware capabilities of a single terminal. Summary of the Invention

[0003] This application provides a communication method and a communication device that aggregates multiple terminals in a network into a single aggregated terminal, thereby utilizing the hardware transmission capabilities, receiving capabilities, and software processing capabilities of the multiple terminals, as well as their transmission resources, to improve the communication performance of the multiple terminals.

[0004] Firstly, a communication method is provided that can be applied to, or executed by, a terminal-side device. This terminal-side device can be a terminal, a component for the terminal (such as a chip circuit, which may be a modem chip, also known as a baseband chip, or a system-on-a-chip (SoC) or system-in-package (SIP) chip containing a modem core), or a logic module or software capable of implementing some or all of the terminal's functions, etc. This application does not limit the scope of the application in this regard.

[0005] The method may include: a first terminal determining a first identifier, the first identifier being associated with a first type of terminal, the first type of terminal being composed of multiple terminals; the first terminal receiving first control information based on the first identifier, the first control information being associated with the first identifier, and the first control information being used to schedule the first type of terminal.

[0006] In the technical solution of this application, multiple terminals are aggregated into a first type of terminal (or a virtual terminal or aggregated terminal), enabling the multiple terminals in the first type of terminal to work collaboratively or communicate, thereby improving the communication performance of the multiple terminals. Furthermore, by associating the first type of terminal with a first identifier, the first terminal can receive first control information for scheduling the first type of terminal based on the first identifier, realizing unified scheduling of the multiple terminals in the first type of terminal and reducing the signaling overhead of scheduling each terminal separately.

[0007] As an example, the multiple terminals in the first type of terminal include the first terminal.

[0008] As an example, the first identifier includes at least one of the following: a first-class terminal identity document (ID), a configuration ID, or a radio network temporary identity (RNTI) scrambled by cyclic redundancy check (CRC).

[0009] Based on the above technical solution, the first terminal can receive the first control information based on at least one of the aforementioned identifiers, thereby improving the flexibility of receiving the first control information. Furthermore, when the first control information simultaneously contains multiple first identifiers, even if one of the first identifiers fails due to interference or error during transmission, the first terminal can still successfully receive the first control information using the other first identifiers, thus further enhancing the reliability and stability of the communication system.

[0010] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: a first terminal receiving second control information, the second control information being used to schedule the first terminal, and in the event of a conflict between the resources indicated by the first control information and the resources indicated by the second control information, the first terminal communicating based on the resources indicated by the first control information.

[0011] Based on the above technical solution, the first terminal can not only receive the first control information for scheduling the first type of terminal, but also the second control information for scheduling the first terminal itself. Furthermore, the above technical solution also provides a handling scheme for resource conflicts indicated by the control information for scheduling the first type of terminal and the control information of the first terminal itself. The first terminal prioritizes communication based on the first control information for scheduling the first type of terminal, avoiding waiting and delays in conflict handling caused by the conflict.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, the second control information includes first indication information, which indicates the transmission mode of the first type of terminal.

[0013] Based on the above technical solution, the second control information for scheduling the first terminal includes first indication information, so that the control information for scheduling a single terminal implicitly indicates the transmission mode of the aggregation terminal, thus preparing for possible subsequent aggregation transmission.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, the RNTI associated with the first control information and the second control information are different; and / or, the formats of the first control information and the second control information are different.

[0015] As an example, the first control information and the second control information have different formats, but the RNTI associated with the first control information and the second control information is the same.

[0016] As an example, the format of the first control information is a first format, and the first format is associated with a first type of terminal.

[0017] Based on the above technical solution, the first terminal can receive the first control information in a format different from the second control information, such as RNTI and / or control information, thereby realizing the reception of the first control information.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, the first type of terminal further includes a second terminal, and the method further includes: the first terminal sending first control information or part of the first control information to the second terminal.

[0019] In conjunction with the first aspect, in some implementations of the first aspect, the first type of terminal further includes a second terminal, and the first terminal receiving the first control information based on the first identifier includes: the first terminal receiving the first control information or a portion of the first control information from the second terminal based on the first identifier.

[0020] Based on the above technical solution, the first terminal can directly receive first control information from the network device, or it can receive first control information or part of the first control information sent by other terminals in the first type of terminals. The first terminal can also send the received first control information to other terminals in the first type of terminals, or it can send only part of the first control information to other terminals in the first type of terminals, ensuring that at least one terminal in the first type of terminals can receive and schedule the first control information. Furthermore, when the second terminal does not have the ability to directly receive the first control information, the first terminal can send the first control information or part of the first control information to the second terminal through an implementation (or inter-terminal interconnection, such as a Wi-Fi hotspot, Bluetooth, satellite link, data cable connection, sidelink connection, etc.).

[0021] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: the first terminal sending capability information, the capability information being used to determine the transmission mode of the first control information and / or the first terminal.

[0022] As an example, the capability information includes at least one of the following: whether the first terminal supports aggregation, the transmission modes supported by the first terminal, and the transmission resources of the first type of terminal.

[0023] Based on the above technical solution, the first terminal sends capability information, and the network device can determine the first control information and / or the transmission mode of the first terminal based on the capability information sent by the first terminal, so as to avoid the first control information and / or the transmission mode of the first terminal directly determined by the network device being unsuitable for the first terminal or exceeding the capability range of the first terminal.

[0024] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: the first terminal sending a second indication message, the second indication message indicating exit from the aggregation mode.

[0025] Based on the above technical solution, the first terminal sends a second instruction message indicating that it will exit the aggregation mode. After the control information, transmission mode, transmission resources, etc. are reconfigured, the first terminal can communicate based on its own capabilities.

[0026] Secondly, a communication method is provided that can be applied to a network-side device, such as being executed by the network-side device. This network-side device can be a network device, a component for a network device (such as a chip circuit, which can be a modem chip, also known as a baseband chip, or a SoC or SIP chip containing a modem core, etc.), or a logic module or software capable of implementing some or all of the functions of a network device, etc., and this application does not limit this.

[0027] The method may include: sending first control information, the first control information being associated with a first identifier, the first control information being used to schedule a first type of terminal, the first identifier being associated with a first type of terminal, and the first type of terminal being composed of multiple terminals.

[0028] In the technical solution of this application, by sending first control information, unified scheduling of multiple terminals in the first type of terminal is realized, thereby enabling the multiple terminals to work collaboratively or communicate, and improving the communication performance of the multiple terminals.

[0029] As an example, the first identifier includes at least one of the following: a first-class terminal ID, a configuration ID, and a CRC-scrambled RNTI.

[0030] Based on the above technical solution, the first control information can be associated with at least one of the above identifiers, which improves the flexibility of sending and receiving the first control information and enhances the reliability and stability of the communication system.

[0031] In conjunction with the second aspect, in some implementations of the second aspect, the method further includes: sending second control information, the second control information being used to schedule a first terminal, the first type of terminal including the first terminal; and, in the event of a conflict between the resources indicated by the first control information and the resources indicated by the second control information, communicating based on the resources indicated by the first control information.

[0032] Based on the above technical solution, the first control information of the first type of terminal is given higher priority. When the second control information sent by the network device conflicts with the first control information, communication can be prioritized based on the resources indicated by the first control information, thus avoiding the waiting and delay in conflict handling caused by the conflict.

[0033] In conjunction with the second aspect, in some implementations of the second aspect, the second control information includes first indication information, which indicates the transmission mode of the first type of terminal.

[0034] Based on the above technical solution, network devices can implicitly indicate the transmission mode of the first type of aggregated terminals in the control information indicating a single terminal, thus preparing for possible subsequent aggregated transmissions.

[0035] In conjunction with the second aspect, in some implementations of the second aspect, the method further includes: the RNTI associated with the first control information and the second control information are different; and / or, the formats of the first control information and the second control information are different.

[0036] As an example, the first control information and the second control information have different formats, but the RNTI associated with the first control information and the second control information is the same.

[0037] As an example, the format of the first control information is a first format, and the first format is associated with a first type of terminal.

[0038] Based on the above technical solution, network devices can associate the first control information of scheduling the first type of terminal with different RNTIs or transmit them in different formats, thereby effectively distinguishing between the two types of control information.

[0039] In conjunction with the second aspect, in some implementations of the second aspect, the method further includes: receiving capability information of the first terminal, and determining the first control information and / or the transmission mode of the first terminal based on the capability information.

[0040] As an example, the capability information includes at least one of the following: whether the first terminal supports aggregation, the transmission modes supported by the first terminal, and the transmission resources of the first type of terminal.

[0041] Based on the above technical solution, the network device determines the first control information and / or the transmission mode of the first terminal according to the capability information from the first terminal, avoiding the situation where the directly preset first control information and / or transmission mode does not match the actual capability of the first terminal, thereby reducing the need for multiple configurations due to adaptation issues and improving the configuration efficiency of the network device.

[0042] In conjunction with the second aspect, in some implementations of the second aspect, the method further includes: receiving second indication information, the second indication information indicating exit from the aggregation mode.

[0043] Based on the above technical solution, the network device can reconfigure the control information based on the second indication information, so that the terminal that sent the second indication information exits the aggregation mode and communicates according to the capabilities of a single terminal according to the reconfigured control information.

Specifically, the apparatus may include units and / or modules for performing the method in any of the possible implementations of the first to second aspects, such as processing units and / or communication units.

[0069] In this application, unless otherwise specified or in case of logical conflict, the terminology and / or descriptions of different embodiments are consistent and can be referenced by each other. Technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.

[0070] I. In this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. In the textual description of this application, the character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, and c can mean: a, or, b, or, c, or, a and b, or, a and c, or, b and c, or, a, b, and c. Here, a, b, and c can each be single or multiple.

[0071] II. In this application, the terms "first," "second," and various numerical designations (e.g., #1, #2, etc.) indicate distinctions made for ease of description and are not intended to limit the scope of the embodiments of this application. For example, they may distinguish different messages, rather than describing a specific order or sequence. It should be understood that such descriptions can be interchanged where appropriate to describe solutions other than those in the embodiments of this application.

[0072] Third, in this application, descriptions such as "when," "under the circumstances," and "if" all refer to the device making corresponding processing under certain objective circumstances, and are not time-limited, nor do they require the device to make a judgment action when implementing it, nor do they imply any other limitations.

[0073] IV. In this application, "instruction" or "for instruction" can include both direct (or explicit) and indirect (or implicit) instruction. When describing instruction information as indicating A, it can include whether the instruction information directly or indirectly indicates A, but does not necessarily mean that the instruction information carries A. For example, in the case of indirect (or implicit) instruction, the receiving end of the instruction information can obtain A based on the parameters indicated by the instruction information, combined with other rules or parameters, or through deduction.

[0074] V. The indication methods involved in the embodiments of this application should be understood to cover various methods that enable the party to be indicated to obtain the information to be indicated. The information to be indicated can be sent as a whole or divided into multiple sub-information and sent separately. Moreover, the sending period and / or sending time of these sub-information can be the same or different. This application does not limit the sending method, for example.

[0075] VI. In this application, "protocol" can refer to standard protocols in the field of communications, such as 5G protocols, new radio (NR) protocols, and related protocols applied to future communication systems; this application does not limit this term. "Predefined" can include predefined terms, such as protocol definitions. "Preconfiguration" can be implemented by pre-storing corresponding codes, tables, or other means that can be used to indicate relevant information in the device; this application does not limit the implementation method.

[0076] VII. In this application, "communication" can also be described as "data transmission," "information transmission," "data processing," etc. "Transmission" includes "sending" and "receiving." For example, transmission can be uplink transmission, such as a terminal device sending a signal to a network device; transmission can also be downlink transmission, such as a network device sending a signal to a terminal device; transmission can also be sidelink transmission, such as a terminal device sending a signal to another terminal device. For example, "transmission" can be air interface level transmission, or it can be signal transmission from a chip input (I) / output (O) port, rather than air interface level transmission.

[0077] 8. In this application, terms such as “message”, “information”, “signal” or “information element (IE)” can be used interchangeably. There are no restrictions on the name of the message or information, as long as it can achieve the corresponding function.

[0078] 9. "Sending information to XX (device)" can be understood as the destination of the information being that device. This can include sending information directly or indirectly to that device. "Receiving information from XX (device), or receiving information from XX (device)" can be understood as the source of the information being that device. This can include receiving information directly or indirectly from that device. Information may undergo necessary processing between the source and destination, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be understood in a similar way, and will not be repeated here. In addition, "sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface. In other words, "sending" or "receiving" can be performed between devices, for example, network devices and terminal devices can send or receive information through an air interface, or "sending" or "receiving" can be performed within a device, for example, through a bus, wiring, or interface between components, modules, chips, software modules, or hardware modules within the device.

[0079] 10. In this application, terms such as "exemplarily" and "for example" are used to indicate examples, illustrations, or descriptions to present concepts in a specific manner. Any embodiment or design described as an "example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. In the embodiments of this application, the terms "of," "corresponding (relevant)," "corresponding," and "associate" may sometimes be used interchangeably, and it should be noted that their intended meanings are consistent unless their distinctions are emphasized.

[0080] XI. In this application, configuration can be signaling configuration or can be described as configuring signaling. For example, signaling configuration includes configuration using signaling sent by network devices, which can be radio resource control (RRC) messages, downlink control information (DCI) messages, or system information blocks (SIBs). Optionally, signaling configuration can also be configured to the terminal device or network device by pre-configured signaling, or configured to the terminal device or network device through pre-configuration. Here, pre-configuration means defining or configuring the values ​​of corresponding parameters in advance by means of a protocol, and storing them in the terminal device or network device when communicating with the terminal device or network device. The pre-configured messages can be modified or updated when the terminal device or network device is connected to the network.

[0081] 12. This application will present various aspects, embodiments, or features relating to systems that may include multiple devices, components, modules, etc. Each system may include devices, components, modules, etc., other than those illustrated, and / or may not include all and all of the devices, components, modules, etc. discussed in conjunction with the accompanying drawings.

As those skilled in the art will know, with the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0083] XIV. In the various embodiments of this application, the sequence number of each process does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application. The terms "comprising," "including," "having," and their variations all mean "including but not limited to," unless otherwise specifically emphasized.

A side unit (RSU), or a device built into the aforementioned device (e.g., a communication module, modem, or chip in the aforementioned device), or other processing device connected to a wireless modem.

[0090] It should be understood that in certain scenarios, a UE can also be used as a base station. For example, a UE can act as a scheduling entity, providing sidelink signaling between UEs in scenarios such as V2X, D2D, or P2P.

[0091] In this embodiment, the device for implementing the functions of a terminal device, i.e., the terminal device, can be the terminal device itself, or it can be any device capable of supporting the terminal device in implementing the functions, such as a chip system, chip, circuit, or communication module (i.e., a communication module that performs communication functions). This device can be installed in the terminal device. In this embodiment, the chip system can be composed of chips, or it can include chips and other discrete devices. Furthermore, the device can also be configured with program instructions for performing corresponding communication functions.

[0092] The network device in this application embodiment can be a device or module with corresponding communication functions.

[0093] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0094] In some deployments, the network devices mentioned in the embodiments of this application may be devices including CU, or DU, or devices including CU and DU, or devices with control plane CU nodes (central unit-control plane (CU-CP)) and user plane CU nodes (central unit-user plane (CU-UP)) and DU nodes.

For example, a radio access network can also be an open radio access network (O-RAN or ORAN) architecture. In an O-RAN system, CU can also be called an open CU (open CU, O-CU), DU can also be called an open DU (open DU, O-DU), CU-CP can also be called an open CU-CP (O-CU-CP), CU-UP can also be called an open CU-UP (O-CU-UP), and RU can also be called an open RU (open RU, O-RU). Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0097] In this embodiment, the device for implementing the functions of a network device can be a network device itself, or a device capable of supporting the network device in implementing those functions, such as a chip system, chip, circuit, or communication module (i.e., a communication module that performs communication functions). This device can be installed within the network device. In this embodiment, the chip system can be composed of chips, or it can include chips and other discrete devices. Furthermore, the device can be configured with program instructions for performing corresponding communication functions. This embodiment only uses a network device as an example to illustrate the device for implementing the functions of a network device, and does not limit the solution of this embodiment.

[0098] Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located.

[0099] See Figure 1 As an example, Figure 1 This is a schematic diagram of a wireless communication system applicable to embodiments of this application. For example... Figure 1 As shown, the wireless communication system includes a wireless access network 100. The wireless access network 100 can be a next-generation (e.g., future or later) wireless access network, or a traditional (e.g., 5G, 4G, 3G, or 2G) wireless access network. One or more terminal devices (120a-120j, collectively referred to as 120) can be interconnected or connected to one or more network devices (110a, 110b, collectively referred to as 110) within the wireless access network 100. Network elements in the wireless communication system are connected via interfaces (e.g., NG, Xn) or over-the-air interfaces.

[0100] When network devices and terminal devices communicate, the network device can manage one or more cells, and a cell can include at least one terminal device. A cell can be understood as an area within the wireless signal coverage range of the network device.

[0101] Figure 1 This is just an illustration; the wireless communication system may also include other devices, such as core network equipment, wireless relay equipment, and / or wireless backhaul equipment. Figure 1 It is not shown in the middle.

[0102] See Figure 2 As an example, Figure 2 This is a schematic diagram of another wireless communication system applicable to embodiments of this application. This wireless communication system may be referred to as an ORAN system, for example. The wireless communication system may include a core network, access network equipment, and a UE. As an example, the ORAN system may also include... Figure 2 Other components besides those shown are not specifically limited in this application.

[0103] Access network devices can communicate with the core network (CN) via a backhaul link. Access network devices can also communicate with the UE via the air interface. Specifically, the BBU in the access network device communicates with the core network via the backhaul link. The RU in the access network device communicates with at least one UE via the air interface. The BBU communicates with at least one RU via a fronthaul link; the BBU and RU may or may not be co-located. The BBU includes at least one CU and at least one DU, and the CU and DU can communicate with each other via at least one midhaul link.

[0104] See Figure 3 As an example, Figure 3 This is a schematic diagram of an access network device applicable to embodiments of this application.

[0105] Optionally, the access network equipment includes a CU. The CU is a logical node that carries the radio resource control (RRC), service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of the access network equipment. The CU can connect to network nodes such as the core network through interfaces, such as the E2 interface. The CU may have some core network functions. The CU (e.g., the PDCP layer and / or higher) connects to the DU (e.g., the radio link control (RLC) layer and lower layers of the DU) through interfaces, such as the F1 interface. Optionally, the F1 interface can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is the application protocol of the F1 interface, defining the signaling procedures of F1 in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0106] As an example, a CU includes CU-CP and CU-UP. CU-CP is a logical node carrying the control plane (PDCP-C) layer, which carries the RRC layer and the Packet Data Convergence Protocol layer, and is used to implement the CU's control plane functions. CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements in the core network can be access and mobility function (AMF) network elements, such as the access and mobility management function (AMF) in a 5G system. The AMF network element is responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover. CU-UP is a logical node carrying the user plane (PDCP-U) layer, which carries the SDAP layer and the Packet Data Convergence Protocol layer, and is used to implement the CU's user plane functions. CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements in the core network, such as the user plane function (UPF) in a 5G system, are responsible for data forwarding and receiving in terminal devices. The above CU and DU configurations are merely examples. In practical applications, the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or to have only some protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of the CU or DU can be divided according to service type or other system requirements. For example, based on latency, functions that require low latency can be placed in the DU, while functions that do not require low latency can be placed in the CU.

[0107] Optionally, the access network equipment includes a DU. For example... Figure 3 As shown, a DU is a logical node that carries the RLC layer, medium access control (MAC) layer, higher physical layer (Higher PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU connects to the RU through interfaces, which can be fronthaul interfaces. In some examples, the Higher PHY layer includes the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation.

[0108] Optionally, the access network equipment includes a RU. For example... Figure 3 As shown, the RU is a logical node that carries both lower physical layer (Lower PHY) and radio frequency (RF) processing. In some examples, the RU can be a 3GPP transmission reception point (TRP), a remote radiohead (RRH), or other similar entities. In some examples, the Lower-PHY includes PHY processing functions such as fast Fourier transform (FFT), inverse fast Fourier transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more UEs via a radio link (such as an RF chain).

[0109] The DU and RU can be co-located or not. The DU and RU exchange control plane and user plane information via a fronthaul link through a lower-layer split CUS-plane (LLS-CUS-Plane) (or O-RANCUS-Plane) interface. Here, CUS-Plane represents the control plane (C-Plane), user plane (UPlane), and synchronization plane (S-Plane) (CUS-Plane). LLS-CUS may include a lower-layer split control (LLS-C) interface providing the control plane and a lower-layer split user (LLS-U) interface providing the user plane. Additionally, LLS-CUS may include a lower-layer split synchronization (LLS-S) interface providing the synchronization plane. In some examples, the control plane (or control plane) refers to the real-time control between the DU and RU. The DU and RU exchange management plane information via the lower-layer split management (LLS-M) interface of the fronthaul link. The management plane (M-Plane) refers to the non-real-time management operations between the DU and RU.

[0110] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0111] The above Figures 1 to 3 For illustrative purposes only, the embodiments described in this application are not limited thereto.

[0112] The following explains some of the technical terms used in the embodiments of this application:

[0113] 1. Resources:

[0114] In communication protocols, reference signals are configured in the form of resources. Network devices configure various reference signals to terminal devices in the form of resources. A resource is a configuration information unit, which usually includes parameters related to a reference signal, such as the time-frequency resource location of the reference signal, the number of ports, the time domain type (periodic / semi-static / aperiodic), etc.

[0115] Resources can be either uplink or downlink signal resources. Uplink signals include, but are not limited to, sounding reference signals (SRS) and demodulation reference signals (DMRS). Downlink signals include, but are not limited to, channel state information reference signals (CSI-RS), cell specific reference signals (CS-RS), user equipment specific reference signals (US-RS), DMRS, and synchronization system / physical broadcast channel blocks (SS / PBCH blocks). The SS / PBCH block can be abbreviated as synchronization signal block (SSB).

[0116] 2. Physical downlink control channel (PDCCH):

[0117] In mobile communication systems, the PDCCH is used to transmit DCI (Digital Downlink Control Channel). The signal carried on the PDCCH is called the PDCCH signal. In some embodiments, the PDCCH signal can be simply referred to as PDCCH. In other words, PDCCH can refer to the Physical Downlink Control Channel, or it can refer to the signals transmitted on the Physical Downlink Control Channel.

[0118] Before transmitting PDCCH, network devices need to send PDCCH configuration (such as control resource set (CORESET) and search space (SS)) to terminal devices to configure relevant parameters for PDCCH transmission and assist terminal devices in receiving PDCCH.

[0119] 3. CORESET:

[0120] It is mainly used to configure the frequency domain resource information of the PDCCH (such as which resource blocks (RBs) it occupies) and some time domain resource information (such as how many symbols it occupies). Network devices can configure one or more CORESETs for terminal devices. A CORESET can be associated with one or more SSs.

[0121] In some embodiments, the resources configured by CORESET (such as one or more symbols, one or more RBs, etc.) may also be referred to as CORESET. In other words, CORESET can be used to represent a resource or a configuration parameter of a resource.

[0122] 4. SS:

[0123] It is mainly used to configure the time-domain resource information of PDCCH, or to configure the relevant information of PDCCH blind detection. For example, the search space set may include: time-domain period (or blind detection period), which indicates how many slots the SS interval occurs once; and a monitoring occasion (MO) within a slot, which indicates the possible symbol positions of PDCCH within a slot.

[0124] In some embodiments, the resource configured by SS may also be referred to as SS. In other words, SS can be used to represent a resource or a configuration parameter of a resource.

[0125] 5. PDCCH blind inspection:

[0126] This refers to a terminal device attempting to receive a PDCCH at various resource locations where a PDCCH might exist (i.e., various candidate PDCCHs) using a blind testing method. Specifically, the process of the terminal device traversing each candidate PDCCH and sequentially determining whether its PDCCH exists at the resource location corresponding to each candidate PDCCH is called blind testing. It can be understood that which candidate PDCCHs the terminal device traverses is pre-configured for that terminal device by the network equipment.

[0127] As mentioned above, with the development of future communication technologies, it will be difficult to improve the communication performance of terminal devices by enhancing the hardware capabilities of individual terminals.

[0128] In view of this, this application proposes to improve the communication performance of multiple terminals by aggregating them into a single aggregated terminal, thereby utilizing the hardware transmission and reception capabilities, software processing capabilities, and transmission resources of the multiple terminals. Furthermore, considering that existing DCI mechanisms cannot achieve unified scheduling of aggregated terminals formed by multiple terminals, a new scheduling mechanism needs to be designed to support the unified scheduling of aggregated terminals formed by multiple terminals.

[0129] The methods provided by the embodiments of this application will be described in detail below with reference to the accompanying drawings. The embodiments provided by this application can be applied to the above-described embodiments. Figures 1-3 The scenarios shown are not limited. Furthermore, the terminology used below can be referenced in the preceding explanations and will not be repeated hereafter. For ease of description, the following examples use the terminal side and network side as illustrations. As an example, the terminal-side method can be executed by a terminal-side device, such as a terminal device, or by components of the terminal device (e.g., a chip, chip system, circuit, or communication module), or by logic modules or software that implement all or part of the functions of the terminal device. As an example, the network-side method can be executed by a network-side device, such as a network device, or by components of the network device (e.g., a chip, chip system, circuit, or communication module), or by logic modules or software that implement all or part of the functions of the network device. Furthermore, the steps described below as being executed by a single execution entity can also be divided into steps executed by multiple execution entities, which can be logically and / or physically separated.

[0130] Figure 4 A schematic diagram of a communication method 400 provided in an embodiment of this application is shown below. Figure 4 As shown, the method includes at least the following steps.

[0131] S410, the first terminal determines the first identifier. The first identifier is associated with a first type of terminal, which includes multiple terminals.

[0132] The first type of terminal refers to a virtual terminal formed by the aggregation of multiple terminals. In other words, when multiple terminals in a communication network are uniformly scheduled or work collaboratively to achieve a certain communication function, these multiple terminals can be collectively referred to as first-type terminals. It can be understood that a first-type terminal can use the capabilities of all terminals within it, such as hardware transmission capabilities, hardware reception capabilities, and software processing capabilities. It can also be understood that a first-type terminal can use the transmission resources of all terminals within it, such as frequency domain resources, spatial domain resources, and time domain resources allocated or scheduled by the base station.

[0133] In this context, "aggregation" can also be replaced with "synthesis," "integration," "collection," "combination," etc. It can be understood that aggregating multiple terminals into a single Type I terminal does not necessarily require performing the aggregation action. Rather, it refers to the unified scheduling of multiple terminals through network devices to achieve a certain communication function based on these multiple terminals. In other words, a Type I terminal can be a virtual terminal.

[0134] The term "first type of terminal" may also be referred to as any of the following: "aggregated terminal," "super terminal," "aggregated group," "virtual terminal," etc., and its name does not limit the scope of protection of the embodiments of this application. Without loss of generality, the following description uses the first type of terminal as an example.

[0135] The first identifier is associated with the first type of terminal and has at least two possible implementation methods.

[0136] In the first possible implementation, the first identifier represents the identifier of the first type of terminal; in other words, the first type of terminal can be identified through the first identifier.

[0137] For example, as shown in Table 1, suppose there are two Class 1 terminals, denoted as Class 1 terminal #1 and Class 1 terminal #2. These two Class 1 terminals are each associated with a Class 1 identifier, such as ID#1 and ID#2. Assuming ID#1 is associated with Class 1 terminal #1 and ID#2 is associated with Class 1 terminal #2, then the network device can schedule Class 1 terminal #1 through ID#1 and Class 1 terminal #2 through ID#2.

[0138] Table 1

[0139] Type 1 terminal First Identification Type 1 Terminal #1 ID#1 Type 1 Terminal #2 ID#2

[0140] In the second possible implementation, the first identifier represents a unified identifier for multiple terminals in the first type of terminals. In other words, the first identifier is associated with each terminal in the first type of terminals, meaning that each terminal in the first type of terminals can determine its belonging to the first type of terminal through the first identifier.

[0141] For example, as shown in Table 2, ID#1 is associated with terminal #1, terminal #2, and terminal #3, and ID#2 is associated with terminal #4, terminal #5, and terminal #6. Then, the network device can schedule the first type of terminal #1, which is aggregated from terminal #1, terminal #2, and terminal #3, through ID#1, and schedule the first type of terminal #2, which is aggregated from terminal #4, terminal #5, and terminal #6, through ID#2.

[0142] Table 2

[0143] First Identification The first type of terminal includes the following terminals ID#1 Terminal #1, Terminal #2, Terminal #3 ID#2 Terminal #4, Terminal #5, Terminal #6

[0144] It should be understood that the table above is for illustrative purposes only and is not limited thereto. For example, a Class I terminal may include more or fewer terminals. As another example, different Class I terminals may contain the same type of terminal. Yet another example is the inclusion of more Class I terminal identifiers.

[0145] The first terminal determines the first identifier in at least the following two possible implementations.

[0146] In one possible implementation, the first terminal determines its own first identifier. Specifically, the first terminal determines its first identifier based on the first type of terminal it belongs to. For example, in Table 2, terminal #1 determines its first identifier as ID#1 based on the first type of terminal it belongs to; and terminal #5 determines its first identifier as ID#2 based on the first type of terminal it belongs to.

[0147] There are no restrictions on how a first terminal determines its own first-category terminal. For example, the relationship between terminals and first-category terminals can be predefined or configured. Taking Table 2 as an example, it can be predefined or configured that: terminals #1, #2, and #3 belong to one first-category terminal, while terminals #4, #5, and #6 belong to another first-category terminal.

[0148] In a second possible implementation, the first terminal receives a first identifier. Specifically, the network device can send the first identifier associated with the first type of terminal to which the first terminal belongs to, or the network device can send the first identifier associated with the first terminal to the first terminal.

[0149] S420, the first terminal receives the first control information.

[0150] The first control information is associated with the first identifier and is used to schedule the first type of terminal.

[0151] The first terminal can receive first control information based on a first identifier. For example, if the first terminal determines that the first identifier associated with its own first type of terminal is ID#1, and the first control information is associated with ID#1, then the first terminal determines that the first control information is the control information for scheduling the first type of terminal to which the terminal belongs.

[0152] In the embodiments of this application, the association of the first control information with the first identifier is mentioned several times, and its meaning is explained uniformly here. Specifically, if the first control information includes the first identifier, it can be said that the first control information is associated with the first identifier; or, if the first control information can be identified through the first identifier, it can be said that the first control information is related to the first identifier, and it can be understood that the first control information is associated with the first identifier; or, if the first control information can be identified through other identifiers associated with the first identifier, it can be said that the first control information is related to the first identifier, and it can be understood that the first control information is associated with the first identifier.

[0153] Optionally, the first identifier includes at least one of the following: a first-class terminal ID, a configuration ID, and a CRC-scrambled RNTI. Several examples are described below.

[0154] Example 1: The first identifier includes the first type of terminal ID, that is, the first control information is associated with the first type of terminal ID.

[0155] The first type of terminal ID, also known as the aggregation group ID, can provide a unified identity for terminals that need to work collaboratively or be uniformly scheduled.

[0156] In this example, the first control information is associated with the first type of terminal ID. Therefore, for a certain first type of terminal, the first control information for itself can be determined based on the first type of terminal ID.

[0157] Example 2: The first identifier includes the configuration ID, which is the configuration ID associated with the first control information.

[0158] The configuration ID is an identifier used to identify resource allocation and scheduling strategies. For example, the configuration may include some or all of the parameters such as time-frequency resources, modulation and coding scheme (MCS), and hybrid automatic repeat request (HARQ).

[0159] In this example, the first control information is associated with the configuration ID. Therefore, different configurations can be notified to the first type of terminal through different first control information.

[0160] Example 3: The first identifier includes a CRC-scrambled RNTI, that is, the first control information is associated with a CRC-scrambled RNTI.

[0161] In this system, the RNTI serves as a temporary identifier for the terminal, while the CRC scrambling operation generates a scrambling check sequence by combining the binary value of the RNTI with the CRC checksum using an algorithm (such as a bitwise XOR operator). The receiving end can descramble the CRC using its own RNTI and verify data integrity, ensuring that the information is correctly decoded only by the target terminal. By combining RNTI and CRC, the directionality and reliability of data transmission are achieved.

[0162] In this example, the RNTI is the RNTI of a first-class terminal. The RNTI of the first-class terminal may be named X-RNTI, where X can be one or more English letters. The RNTI may also be replaced by other names with similar functions. The X-RNTI can be scrambled by CRC.

[0163] In this example, the first control information is associated with a CRC-scrambled RNTI, which is the RNTI of the first type of terminal. Therefore, the first type of terminal can determine the first control information for itself based on the CRC-scrambled RNTI.

[0164] Example 4: The first identifier includes multiple identifiers, for example, the first identifier includes a first type of terminal ID and a CRC-scrambled RNTI.

[0165] In this example, the first control information is associated with the first type of terminal ID and the CRC-scrambled RNTI. Therefore, for a certain first type of terminal, the first control information for itself can be determined based on the first type of terminal ID, or it can be determined based on the RNTI of the first type of terminal.

[0166] The above is an example illustration, and the embodiments of this application are not limited thereto. That is, the first identifier may include at least one of the following: a first type of terminal ID, a configuration ID, and a CRC-scrambled RNTI. In other words, the first control information may be associated with at least one of the above.

[0167] The first control information is used to schedule the first type of terminal and may include: the first control information instructing the resources of the first type of terminal; in other words, the first control information instructing the resources used for communication by the first type of terminal. Thus, the first type of terminal can communicate based on the resources indicated by the first control information. The communication includes one or more of the following: measuring reference signals such as CSI-RS, transmitting uplink reference signals such as SRS, receiving downlink data, for example, receiving signals on a designated physical downlink shared channel (PDSCH) resource, and transmitting uplink data, for example, transmitting signals on a designated physical uplink shared channel (PUCCH) or PUSCH resource.

[0168] The first control information indicates the resources of the first type of terminal, and there are two possible implementation methods.

[0169] In one possible implementation, the resource carrying the first control information is a dedicated control channel resource. Multiple terminals in the first type of terminal receive control information specifically used for scheduling resources of the first type of terminal on this dedicated control channel resource. Specifically, this dedicated control channel resource is a control channel resource dedicated to aggregation scheduling, that is, a control channel resource specifically for the first type of terminal.

[0170] Assume that the first type of terminal #1 includes terminal #1 and terminal #2, such as Figure 5 As shown, then Figure 5 Positions T1, T2, and T3 are dedicated control channel resources for the first type of terminal #1. The information carried by these dedicated control channel resources includes first control information, which is used to schedule the first type of terminal #1.

[0171] In some possible examples, if multiple Type 1 terminals exist, they can be scheduled separately using this dedicated control channel resource. For instance, suppose there are two Type 1 terminals, denoted as Type 1 terminal #1 and Type 1 terminal #2. Then, the network device can schedule Type 1 terminal #1 using first control information #1 and Type 1 terminal #2 using first control information #2. Figure 5 For example, a network device can send the first control information #1 at location T1 and the first control information #2 at location T2.

[0172] The second possible implementation involves reusing the existing control channel resources of the terminal to carry the first control information. That is, this control channel resource can transmit both the first control information for scheduling the first type of terminals and the control information for scheduling individual terminals within the first type of terminals. For example, such as... Figure 6 As shown, assuming that the first type of terminal #1 includes terminal #1 and terminal #2, taking terminal #1 as an example, the control channel resources in the dashed box can transmit both the first control information for scheduling the first type of terminal #1 and the control information for scheduling the terminal #1.

[0173] Regarding the first terminal, at least the following scenarios are included.

[0174] In the first scenario, the first terminal belongs to the first type of terminal, meaning that the first type of terminal includes the first terminal.

[0175] Based on this, the first terminal can receive the first control information from the network device side, or it can receive the first control information from other terminals in the first type of terminals. For example, assuming the first type of terminals also includes a second terminal, the second terminal can receive the first control information from the network device side and send the first control information or a portion of the first control information to the first terminal (or other terminals in the first type of terminals besides the first terminal). Correspondingly, the first terminal receives the first control information or a portion of the first control information from the second terminal.

[0176] The second possible scenario is that the first terminal does not belong to the first type of terminal. For example, the first terminal is a terminal with a strong signal in the current network. If the signal strength of the first terminal is greater than or equal to the threshold, assuming that the first type of terminal includes the second terminal, then the first terminal receives the first control information and sends the first control information or part of the information in the first control information to the second terminal (or other terminals in the first type of terminal besides the second terminal).

[0177] In some possible examples, the information transmission and reception methods between the first terminal and the second terminal include at least one of the following: WIFI hotspot, Bluetooth, Starlight, data cable connection, sidelink connection, etc.

[0178] Optionally, the first terminal receives second control information. The second control information is used to schedule the first terminal.

[0179] It should be understood that the first control information and the second control information are similar, both being control information, also known as scheduling information. For example, they can be information included in the DCI indicating the scheduling resources, or information that can be used to configure the available authorization information for terminal devices to transmit and receive signals (such as data). As an example, the control information includes resource indications (or resource configurations), which the terminal device can then use to transmit signals with network devices. The difference between the first control information and the second control information is that the first control information is control information for scheduling a first type of terminal, while the second control information is control information for scheduling a single terminal (such as the first terminal).

[0180] In some possible implementations, when the resources indicated by the first control information conflict with the resources indicated by the second control information, the first terminal communicates based on the resources indicated by the first control information. In other words, when the resources received by the first terminal from the scheduling aggregation terminal conflict with the resources of the scheduling single terminal, the first terminal communicates based on the resources indicated by the aggregation terminal.

[0181] In this context, a resource conflict occurs when the resources indicated by the first control information and the resources indicated by the second control information overlap in the time domain and / or frequency domain (e.g., complete overlap, or partial overlap). As an example, when a conflict occurs between the resources indicated by the first control information and the resources indicated by the second control information, the first terminal preferentially uses the RNTI of the first type of terminal for blind detection.

[0182] Assume the first type of terminal includes terminal #1 and terminal #2, such as Figure 7 The diagram shows a conflict between aggregate scheduling and non-aggregate scheduling. Figure 7 (a) is the aggregation-PDCCH of the first type of terminals, wherein the first type of terminals includes terminal #1 and terminal #2, and the first control information of the first type of terminals is scheduled on this aggregation-PDCCH. Figure 7 (b) represents the PDCCH of terminal #1. Figure 7 (c) represents the PDCCH of terminal #2, which carries the second control information for scheduling terminals #1 and #2 respectively. That is, terminal #1-PDCCH carries the second control information #1 for scheduling terminal #1, and terminal #2-PDCCH carries the second control information #2 for scheduling terminal #2. Figure 7 As shown, at T1, T3, and T5, the aggregation-PDCCH of the first type of terminal and the terminal #1-PDCCH conflict in the time domain. For terminal #1, the first control information corresponding to the aggregation-PDCCH is detected first, while the second control information #1 corresponding to the terminal #1-PDCCH is not detected. For example, in the case of indicated resource conflict, the CRC scrambled RNTI of the first type of terminal is used first for blind detection.

[0183] The above is an illustrative example, and the embodiments of this application are not limited thereto. For example, when the resources of the scheduling aggregation terminal received by the first terminal conflict with the resources of the scheduling single terminal, the first terminal may also communicate based on the resources of the scheduling single terminal.

[0184] Optionally, the RNTIs associated with the first control information and the second control information are different, and / or the formats of the first control information and the second control information are different. Several examples are given below.

[0185] Example 1: The RNTIs associated with the first and second control information are different. Based on this, the RNTI can be used to identify whether it is the first or the second control information, that is, the RNTI can be used to identify whether the control information is for scheduling a single terminal or a type of terminal.

[0186] For example, the RNTI associated with the first control information is one of at least one RNTI#1, and the RNTI associated with the second control information is one of at least one RNTI#2, wherein RNTI#1 and RNTI#2 are different.

[0187] Example 2 shows that the first and second control information have different formats. Based on this, the format of the control information can be used to identify whether it is the first or second control information; that is, the format of the control information can be used to identify whether the control information is for scheduling a single terminal or a type of terminal.

[0188] For example, the first control information is in a first format, which is associated with a first type of terminal. The second control information is in a second format. The first and second formats are different. The first format can be used to identify that the control information is used to schedule the first type of terminal.

[0189] Example 3 shows that the RNTIs associated with the first and second control information are different, and the formats of the first and second control information are also different. This example can be referenced from the descriptions in Examples 1 and 2, and will not be repeated here.

[0190] Example 4 shows that the RNTIs associated with the first and second control information are different, even though the formats of the first and second control information are the same. This example can be referenced from Example 1, where the RNTI is used to identify whether it is the first or second control information; this will not be elaborated upon here.

[0191] Example 5 shows that the first and second control information are associated with the same RNTI, but their formats are different. This example can be referenced from Example 2, where the format of the control information is used to identify whether it is the first or second control information; this will not be elaborated upon here.

[0192] Optionally, the second control information includes first indication information, which is used to indicate the transmission mode of the first type of terminal. The transmission mode of the first type of terminal can be any of the following: 1) spatial division multiplexing transmission, that is, multiple terminals use different antenna ports to transmit simultaneously; 2) frequency division multiplexing transmission, that is, multiple terminals use orthogonal frequency domain resources to transmit simultaneously; 3) time division transmission, that is, multiple terminals transmit sequentially in time.

[0193] In some examples, the parameter information in the aggregated transmission can be determined based on the capability information of the aggregating terminal. For example, the maximum value / bit length of the parameter information in the aggregated transmission is determined based on the first type of terminal; or, the parameter information in the aggregated transmission can refer to the corresponding aggregation configuration information, such as pre-configured parameter information.

[0194] For example, taking the first type of terminal, which includes terminal #1 and terminal #2, the parameter information in the aggregated transmission, exemplified by the number of DMRS ports and the field length in the second control information indicating the DMRS ports, is shown in Table 3, where B is greater than or equal to A. It should be understood that the number of ports and field lengths in the table below are merely examples and do not constitute a limitation; the aggregated configuration information is not limited to the configurations shown in Table 3.

[0197] Optionally, method 400 further includes: S401, the first terminal sends capability information.

[0198] The capability information is used to determine the transmission mode of the first control information and / or the first terminal.

[0199] In some possible implementations, the capability information sent by the first terminal is the capability information of the first terminal itself. The network device receives the capability information of the first terminal and other multiple terminals, determines the overall capability information of all the received terminals, and uses the overall capability information as the capability information of the first type of terminal, thereby determining the transmission mode of the first control information and / or the first terminal.

[0200] In some other possible implementations, the capability information sent by the first terminal is the capability information of a first type of terminal to which the first terminal belongs. Based on the capability information of the first type of terminal sent by the first terminal, the network device determines the first control information and / or the transmission mode of the first terminal. When the network device receives the capability information of the first type of terminal, it knows that the change in terminal capability is due to aggregation enabling.

[0201] As an example, the capability information includes at least one of the following: whether the first terminal supports aggregation, the transmission modes supported by the first terminal, and the transmission resources of the first type of terminal. The transmission modes supported by the first terminal are the transmission modes used by the first type of terminal in the aggregated transmission supported by the first terminal, as mentioned above, including space division multiplexing transmission, frequency division multiplexing transmission, and time division transmission.

[0202] The transmission resources of a Class I terminal include at least one of the following: the number of aggregated antenna ports, the number of supported transport streams, the total number of uplink and / or downlink antennas, the total uplink transmit power, and the uplink and / or downlink transmission bandwidth. This information is explained below.

[0203] 1) Aggregated antenna port count: The antenna port count represents the number of independent transmission channels between the base station and the terminal. Each port corresponds to a specific reference signal, which the terminal uses to distinguish data streams. The aggregated antenna port count represents the total number of antenna ports used for transmission by the first type of terminal.

[0204] 2) Number of supported transmission streams: This indicates the number of independent sensing data streams transmitted by the first type of terminal after aggregation when multiple antennas are transmitting simultaneously and / or the number of data streams transmitted.

[0205] 3) Total number of uplink and / or downlink antennas: refers to the total number of physical antennas at the transmitting and receiving ends of the communication system.

[0206] 4) Total uplink transmit power: refers to the radio frequency power used by the terminal when sending signals to the network device.

[0207] 5) Uplink and / or downlink transmission bandwidth: refers to the range of frequency resources used for data transmission.

[0208] For network devices, the parameter information in the transmission mode of the first type of terminal can be determined based on the capability information provided by the terminal device. For example, if the capability information sent by the first terminal includes the aggregated number of antenna ports, and assuming the aggregated number of antenna ports included in the capability information is P1, then the number of antenna ports in the first control information determined by the network device for the first type of terminal can be P1 or less than P1. As another example, if the capability information sent by the first terminal includes the number of supported transport streams, then the number of transport streams determined by the network device for the first type of terminal must be less than or equal to the number of transport streams in that capability information.

[0209] Optionally, the first terminal may also send aggregation conditions, such as the period and duration for which the first terminal can enable aggregation.

[0210] In some possible implementations, the network device receives the capability information and aggregation conditions of the first terminal and adjusts the configuration of the first terminal, such as configuring uplink and downlink data channel transmission and measurement configuration.

[0211] There are at least two ways to configure network devices.

[0212] The first possible implementation is reconfiguration, that is, the network device reconfigures the configuration information of the first terminal based on the received capability information and aggregation conditions to adapt to the needs of aggregated transmission.

[0213] Another possible implementation is incremental configuration. That is, the terminals in the first category (such as the first terminal) retain their pre-aggregation configuration, and the network device further configures a dedicated configuration for aggregated transmission of the first category of terminals, thereby reducing configuration complexity and signaling overhead. It should be understood that when using incremental configuration, the dedicated configuration for aggregated transmission only takes effect when aggregated transmission is enabled.

[0214] Optionally, method 400 further includes: S421, the first terminal sends second indication information. The second indication information is used to indicate exiting the aggregation mode.

[0215] When the network device receives the second instruction information sent by the first terminal, it reconfigures the first terminal according to its original capabilities, thereby scheduling the first terminal.
