[0001] The present disclosure relates to the technical field of communication, and in particular, to a carrier information determination method, a carrier information determination device, a terminal, a network device, a communication system, and a storage medium. BACKGROUND

[0002] The carrier technology mainly expands the capacity of the wireless communication pipeline.

The network element can be virtual or physical. The core network includes, for example, at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next generation core (NGC).

[0090] In some embodiments, the access network device can be composed of a central unit (CU) and a distributed unit (DU), where the CU can also be referred to as a control unit. The CU-DU structure can split the protocol layers of the access network device, and some of the protocol layers are controlled by the CU, and the remaining part or all of the protocol layers are distributed in the DU and controlled by the CU, but is not limited thereto.

[0091] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed by the embodiments of the present disclosure. Those skilled in the art can know that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions proposed by the embodiments of the present disclosure are also applicable to similar technical problems.

[0092] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1 or part of the subjects, but are not limited thereto.

[0093] Embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other communication methods, next-generation system expanded based thereon, and the like. Further, a plurality of systems can be combined (for example, combination of LTE or LTE-A and 5G, and the like).

[0094] In some embodiments, the carrier technology is mainly an expansion of the wireless communication pipe capacity, for example, although the carriers can be divided into PCell (primary cell) and SCell (secondary cell) and the like, so that the different carriers are slightly different in positioning, but the different carriers are not distinguished from the functional layer, for example, different types of services can be transmitted on the same carrier.

[0095] Taking the 5G NR (New Radio) system as an example, for example, URLLC (Ultra-reliable and Low Latency Communications) and eMBB (Enhanced Mobile Broadband) services can be transmitted simultaneously in the same carrier. Since the performance indicators and technical details of the two services are different, in order to meet the different needs of the two services in the same carrier, the NR system needs to design a large number of solutions to solve it, including but not limited to:

[0096] Priority mechanism, such as intra-UE multiplexing;

[0097] Cancellation mechanism, such as Cancel Indicator (CI) and Preemption Indicator (PI);

[0098] Introducing a complex repetition mechanism;

[0099] Introducing a complex Hybrid Automatic Repeat reQuest (HARQ) feedback mechanism;

[0100] Introducing a complex Physical Downlink Control Channel (PDCCH) blind detection mechanism;

[0101] Introducing a complex Physical Downlink Shared Channel (PDSCH) / Physical Uplink Shared Channel (PUSCH) transmission mechanism;

[0102] Introducing a complex Downlink Control Information (DCI) definition.

[0103] With the expansion of services, more advanced technologies are introduced in the 5GA (5G advanced) stage. Since the NR system does not have the ability to hard separate services and technologies in the frequency domain, the protocol design is becoming more and more complex, and the implementation is becoming more and more difficult.

[0104] FIG. 2 is an interaction diagram illustrating a carrier information determination method according to an embodiment of the present disclosure.

[0105] In step S201, the network device sends indication information to the terminal.

[0106] In some embodiments, the indication information is used to indicate a function type of at least one member carrier in a carrier aggregation (CA) carrier.

[0107] In some embodiments, the terminal receives the indication information sent by the network device.

[0108] In step S202, the terminal determines the function type of at least one member carrier in the carrier aggregation according to the indication information.

[0109] In some embodiments, the terminal can determine the function type of at least one member carrier in the carrier aggregation according to a predefined rule. In this case, the network device can also determine the function type of at least one member carrier in the carrier aggregation according to the predefined rule.

[0110] In some embodiments, the terminal can determine, according to the indication information or the predefined rule, that the function types of different member carriers in the carrier aggregation are different.

[0111] According to the embodiments of the present disclosure, the terminal can determine the function type of the member carrier in the carrier aggregation according to the indication information or the predefined rule, according to which each member carrier can correspond to a specific function type instead of all function types, which is conducive to isolating different carriers in terms of function types, so that the same carrier only corresponds to relatively fewer function types, which is conducive to simplifying the protocol.

[0112] In some embodiments, the function type includes at least one of the following:

[0113] a type of supported bearer service;

[0114] a type of supported communication function.

[0115] In some embodiments, the type of service can include at least one of the following:

[0116] immersive communication (IC);

[0117] ubiquitous communication (UC);

[0118] hyper reliable and low latency communication (HRLLC).

[0119] It should be noted that the above-mentioned several types of services are only examples of the types of services of the present disclosure, and the types of services of the present disclosure are not limited to the above-mentioned several types, for example, can also include URLLC, eMBB, etc., and the present disclosure does not limit this.

[0120] In some embodiments, the type of communication function can include at least one of the following:

[0121] Artificial Intelligence (AI);

[0122] Integrated Sensing and Communication (ISAC);

[0123] Internet of Things (IoT);

[0124] Duplex communication, such as Time Division Duplexing, Frequency Division Duplexing (FDD), etc.

[0125] Network Energy Saving (NES).

[0126] It should be noted that the above-mentioned several types of communication functions are only examples of the types of communication functions of the present disclosure, and the types of communication functions of the present disclosure are not limited to the above-mentioned several types, for example, can also include Non Terrestrial Network (NTN) communication, etc., and the present disclosure does not limit this.

[0127] The following several embodiments take the type of function including supporting the type of bearer service as an example to exemplarily illustrate the technical solutions of the present disclosure.

[0128] For example, the terminal communicates based on the carrier aggregation technology, and the member carriers of the carrier aggregation include carrier#1 and carrier#2. It should be noted that the number of member carriers is not limited to two as shown in this embodiment, and the present disclosure does not limit the specific number.

[0129] The terminal determines, based on the indication information or the predefined rule, that the type of bearer service supported by carrier#1 includes URLLC, and the type of bearer service supported by carrier#2 includes eMBB.

[0130] On this basis, the carrier #1 only needs to meet the performance indicators and service details related to URLLC, and does not need to meet the performance indicators and service details related to eMBB; the carrier #2 only needs to meet the performance indicators and service details related to eMBB, and does not need to meet the performance indicators and service details related to URLLC. Compared with the same carrier supporting the terminal to be able to perform each service, the performance indicators and service details required to be met by each carrier in the embodiment are less, which is beneficial to simplify the configuration of each carrier and the related protocol design of the terminal communicating on each carrier.

[0131] It should be noted that the function type of a single member carrier in the embodiment of the disclosure can be one function type or multiple function types, and the disclosure does not limit this. For example, when the function type of a single member carrier is multiple function types, the number of multiple function types is less than a number threshold (for example, can be 3, 4, etc.), so that compared with the same carrier supporting the terminal to be able to perform each service, it is still beneficial to simplify the configuration of each carrier. The function types of different member carriers can or can not have an intersection, and the disclosure does not limit this.

[0132] In some embodiments, the terminal determined according to the indication information or the pre-defined rule can be the function type of at least one member carrier in the carrier aggregation scenario.

[0133] In this case, even if the function type of a single member is relatively small, but the overall function type of the multiple member carriers of the carrier aggregation is relatively large, the terminal communicates based on the multiple carriers of the carrier aggregation, and most of the services and / or functions can still be implemented.

[0134] In some embodiments, the terminal determines the communication behavior on the member carrier according to the function type of the member carrier.

[0135] For example, the terminal determines the communication behavior on the member carrier according to the function type after determining the function type of the member carrier. For example, the communication behavior includes at least one of the following: measurement, transmission, and reception.

[0136] For example, on different member carriers, due to the different function types of the member carriers, the uplink channel or signal supported by the terminal can be different, the downlink channel or signal supported by the terminal can be different, in which case the transmission behavior of the uplink channel or signal supported by the terminal can be different, the reception behavior of the downlink channel or signal supported by the terminal can be different, and the measurement behavior of the terminal can be different.

[0137] The network device can also determine the communication behavior on the member carriers according to the function type, and the communication behavior determined by the network device corresponds to the communication behavior of the terminal. For example, the terminal determines to perform a sending operation, and the network device determines to receive the information sent by the terminal. For example, the terminal determines to perform a receiving operation, and the network device determines to send information to the terminal. For example, the terminal determines to measure a reference signal, and the network device determines to send the reference signal.

[0138] In some embodiments, at least one of the following communication parameters supported by the member carriers of different function types is different:

[0139] frame structure; signal; channel.

[0140] In the case where the function types of the member carriers are different, the communication parameters supported by the member carriers (for example, which can correspond to different types of transmission technologies) can be different, so that the terminal communicates on the member carriers of different function types based on the communication parameters corresponding to the function types, so as to ensure the communication effect.

[0141] For example, the frame structure is pre-configured or pre-defined; for example, the signal is a signal with a specific definition; for example, the channel is a channel with a specific definition; for example, the signal is a signal with corresponding characteristics; for example, the channel is a channel with corresponding characteristics. Wherein, the corresponding characteristics include at least one of the following: pattern, period, resource allocation, etc.

[0142] FIG. 3 is a schematic diagram of a frame structure of a member carrier according to an embodiment of the present disclosure.

[0143] As shown in FIG. 3, for example, taking 6 member carriers carrier#1, carrier#2, carrier#3, carrier#4, carrier#5, carrier#6 as an example, the function type of carrier#1 is an anchor carrier (for example, the carrier accessed and camped by the terminal), the function type of carrier#2 is a sensing service (for example, used for sensing service and / or supporting sensing service), the function type of carrier#3 is AI (for example, supporting AI specific service, data interaction, model interaction, etc.), the function type of carrier#4 is NES, the function type of carrier#5 is IC (used to provide extreme transmission rate and user experience), and the function type of carrier#6 is HRLLC.

[0144] Wherein, based on the characteristics of the sensing service, the frame structure of carrier#2 has a relatively long time length corresponding to the time domain unit (for example, frame, subframe, symbol, etc.) compared with other member carriers, which can be referred to as a sensing-specific frame structure. The time length corresponding to the time domain unit of other carriers is relatively short.

[0145] The following illustrates carrier aggregation by several embodiments.

[0146] In some embodiments, carrier aggregation technology can improve user experience and system capacity, which can be applied in 4G LTE systems, 5G NR systems, and subsequent versions (e.g., 6G) of communication systems.

[0147] The original intention of introducing carrier aggregation is that in the LTE system, the maximum system bandwidth is 20MHz, which limits the improvement of system throughput. With the evolution of technology and the boom of application, users' demand for traffic is increasingly strong. Thanks to the powerful pipeline expansion capability of carrier aggregation technology, LTE systems can meet users' increasingly rich and improved needs.

[0148] In addition, due to the scarcity of spectrum, the fragmentation of spectrum has become increasingly serious as more and more operators enter the market. Carrier aggregation technology can well integrate the discrete spectrum owned by each operator into a whole, improving spectrum utilization efficiency and user experience.

[0149] Due to the more diverse types and quantities of 5G spectrum, carrier aggregation technology also has a wide range of application scenarios in NR systems. For example, the deployment scenarios of carrier aggregation include at least one of the following:

[0150] Inter-band carrier aggregation (Inter band CA);

[0151] Intra-band carrier aggregation (Intra-band CA), such as contiguous carrier aggregation (contiguous CA) and non-contiguous carrier aggregation (non-contiguous CA);

[0152] Time division duplex band carrier aggregation (TDD band CA);

[0153] Frequency division duplex band carrier aggregation (FDD band CA);

[0154] Time division duplex and frequency division duplex band carrier aggregation (TDD+FDD band CA).

[0155] In some embodiments, in addition to being able to improve system throughput, carrier aggregation technology also greatly enriches the deployment scenarios and costs of the network. For example, based on TDD+FDD CA, the advantages of low frequency and wide coverage of FDD frequency bands can be fully utilized to achieve wide coverage, while the advantages of high frequency and flexible bandwidth deployment of TDD frequency bands can be fully utilized to achieve high throughput. For example, by evaluating the channel conditions of different member carriers, more important data can be transmitted on member carriers with good channel conditions, thereby improving the robustness of the network.

[0156] In some embodiments, after the terminal accesses the network on the PCell or the PSCell, the terminal can add a member carrier (e.g., a carrier corresponding to a secondary cell) in the form of secondary cell addition, and work on the configured member carrier.

[0157] The difference between the PCell and the PSCell from the SCell is that the PCell and the PSCell can additionally transmit basic channels and signals such as a common search space (CSS) and provide related configuration information of the SCell.

[0158] It should be noted that the present disclosure does not limit the bandwidth, subcarrier spacing (SCS), and other parameters of the PCell and the SCell.

[0159] In some embodiments, in a carrier aggregation scenario, the scheduling manner can include at least one of the following:

[0160] Cross-carrier scheduling, the network device sends scheduling information on a scheduling carrier to indicate data transmission of the terminal on a scheduled carrier, and the scheduling carrier and the scheduled carrier are different carriers;

[0161] Self-scheduling, the network device sends scheduling information on each member carrier to schedule data transmission on the carrier.

[0162] The following is an exemplary description of the network device determining the function type of at least one member carrier of the carrier aggregation according to the indication information through several embodiments.

[0163] In some embodiments, the indication information includes at least one of the following:

[0164] Direct indication information;

[0165] Indirect indication information.

[0166] In some embodiments, the direct indication information may, for example, include explicit configuration information, and the explicit configuration information can directly carry information about the function type of the member carrier.

[0167] It should be noted that the present disclosure does not limit the channel carrying the direct indication information, the indication manner of the direct indication information, and the like.

[0168] For example, when the function types of N member carriers need to be indicated, each member carrier can correspond to one function type, and the direct indication information can be indicated by ceil(log2(N)) bits.

[0169] In some embodiments, the directly indicated information comprises configuration information of the added carrier corresponding to the added carrier when the network device adds the carrier to the carrier aggregation, and the configuration information comprises a function type of the added carrier.

[0170] For example, the network device can send the corresponding configuration information of the added carrier to the terminal when adding the carrier to the carrier aggregation, and the configuration information can directly indicate the function type of the added carrier.

[0171] In some embodiments, the indirectly indicated information comprises configuration information of the added carrier corresponding to the added carrier when the network device adds the carrier to the carrier aggregation.

[0172] In some embodiments, the indirectly indicated information comprises configuration information of the added carrier corresponding to the added carrier when the network device adds the carrier to the carrier aggregation.

[0173] According to the association relationship between the configuration information and the function type, the function type corresponding to the configuration information is determined as the function type of the added carrier.

[0174] In this embodiment, the indirectly indicated information does not directly indicate the function type of the member carrier, but can indicate the configuration information related to the function type, and the terminal can determine the function type of the member carrier according to the configuration information indicated by the indirectly indicated information for the member carrier.

[0175] In some embodiments, the configuration information of the added carrier comprises at least one of the following:

[0176] Time slot structure information;

[0177] Channel configuration information;

[0178] Frequency domain configuration information;

[0179] Signal configuration information;

[0180] Subcarrier spacing configuration information.

[0181] It should be noted that the configuration information of the added carrier is not limited to the above several kinds, and the disclosure does not limit the specific content contained in the configuration information of the added carrier.

[0182] In some embodiments, the time slot structure information of the carrier comprises, but is not limited to, symbol types within a certain time window, such as downlink symbol (DL symbol), uplink symbol (UL symbol), flexible symbol (Flexible symbol), duplex symbol (Duplex symbol), symbol for sensing, symbol for communication, symbol for AI transmission, silent symbol, symbol not available for specific transmission, etc.

[0183] In some embodiments, the channel configuration information may, for example, comprise at least one of a type of the channel, time domain resources of the channel, frequency domain resources of the channel, a transmission period of the channel, whether the channel is capable of dynamic adjustment, and the like. For example, the channel may comprise at least one of a PBCH (Physical Boardcast Channel), a PDCCH, a PUCCH (Physical Uplink Control Channel), a PDSCH, a PUSCH, and a PRACH (Physical Random Access Channel).

[0184] In some embodiments, the signal configuration information may, for example, comprise at least one of a type of the signal, time domain resources of the signal, frequency domain resources of the signal, a transmission period of the signal, whether the signal is dynamically adjusted, time domain transmission behavior of the signal, and the like. For example, the signal may comprise at least one of a DMRS (Demodulation Reference Signal), a CRS (Cell-specific Reference Signal), a PTRS (Phase Tracking Reference Signal), a CSI-RS (Channel State Information Reference Signal), a SRS (Sounding Reference Signal), a PSS (Primary Synchronization Signal), and a SSS (Secondary Synchronization Signal).

[0185] In some embodiments, the frequency domain configuration information may, for example, comprise at least one of a frequency band, a bandwidth size, and a frequency domain resource location.

[0186] In some embodiments, the SCS configuration information may, for example, indicate a size of a subcarrier spacing of a carrier.

[0187] In some embodiments, the network device may configure an association relationship between a function type and the configuration information for the terminal, or a predefined rule (for example, a protocol agreement) may stipulate the association relationship between the configuration information and the function type. The present disclosure does not limit the manner of determining the association relationship.

[0188] For example, taking the SCS configuration information as an example, the configuration information comprises a 3-member carrier carrier#1, carrier#2, and carrier#3.

[0189] For example, in the association relationship between the function type and the configuration information, the function type corresponding to the SCS of 15 kHz is the NES service, the function type corresponding to the SCS of 30 kHz is the sensing service, and the function type corresponding to the SCS of 60 kHz is the HRLLC service.

[0190] For example, when the network device adds a carrier carrier#1 to the carrier aggregation, the configuration information provided for the carrier#1 includes the SCS of 15 kHz, and the terminal can determine, according to the association relationship between the function type and the configuration information, that the function type corresponding to the carrier#1 is the NES service.

[0191] For example, when the network device adds a carrier carrier#2 to the carrier aggregation, the configuration information provided for the carrier#2 includes the SCS of 30 kHz, and the terminal can determine, according to the association relationship between the function type and the configuration information, that the function type corresponding to the carrier#2 is the sensing service.

[0192] For example, when the network device adds a carrier carrier#3 to the carrier aggregation, the configuration information provided for the carrier#3 includes the SCS of 60 kHz, and the terminal can determine, according to the association relationship between the function type and the configuration information, that the function type corresponding to the carrier#3 is the HRLLC service.

[0193] It should be noted that the above description of the association relationship is only an example of the present disclosure, and the present disclosure does not limit the specific association relationship. For example, the network device provides a sensing-related frame structure for a specific carrier, and determines that the function type of the carrier is sensing; the network device provides NES-related configuration for a specific carrier, and the function type of the carrier is NES; the network device provides high-reliability low-latency related configuration for a specific carrier, and the function type of the carrier is HRLLC.

[0194] The following is an exemplary description of the terminal determining the function type of at least one member carrier of the carrier aggregation according to the predefined rule through several embodiments.

[0195] In some embodiments, the predefined rule includes determining the function type of part or all of the carriers configured by the network device based on the number of carriers configured by the network device (for example, the number of carriers that can be used for data transmission of the terminal), and the at least one member carrier belongs to the carriers configured by the network device.

[0196] In some embodiments, the predefined rule includes determining the function type of the at least one member carrier based on the carrier number of the at least one member carrier.

[0197] In some embodiments, the member carriers of different carrier numbers correspond to the same function type, and / or the member carriers of different carrier numbers correspond to different function types.

[0198] For example, the predefined rule stipulates that, in the case that the network device is configured with N carriers (which can serve as member carriers), then the function type of the carrier numbered i is the i th type, where i is an integer less than or equal to N.

[0199] The number of function types can be less than N, can be equal to N, or can be greater than N, and the disclosure does not limit this. The order of the function types (for example, represented by a serial number) can be indicated by the network device or stipulated by a predefined rule.

[0200] FIGS. 4A-4C are schematic diagrams of the function types of a carrier according to embodiments of the present disclosure.

[0201] For example, the member carriers of different carrier numbers correspond to different function types, and then one numbered member carrier can correspond to one function type.

[0202] For example, the function types include IC, HRLLC, UC, AI, ISAC, IoT, duplex, NES, sensing, anchor carrier, etc. For example, the number of carriers configured by the network device is 4, which are carrier#0, carrier#1, carrier#2, and carrier#3.

[0203] As shown in FIG. 4A, for example, in the above-mentioned order of function types, the first four are anchor carrier, sensing, AI, and NES, respectively, and then the function type of carrier#0 is anchor carrier, the function type of carrier#1 is sensing, the function type of carrier#2 is AI, and the function type of carrier#3 is NES.

[0204] As shown in FIG. 4B, for example, in the above-mentioned order of function types, the first four are anchor carrier, IC, HRLLC, and sensing, respectively, and then the function type of carrier#0 is anchor carrier, the function type of carrier#1 is IC, the function type of carrier#2 is HRLLC, and the function type of carrier#3 is sensing.

[0205] As shown in FIG. 4C, for example, in the above-mentioned order of function types, the first four are anchor carrier, AI, NES, and sensing, respectively, and then the function type of carrier#0 is anchor carrier, the function type of carrier#1 is AI, the function type of carrier#2 is NES, and the function type of carrier#3 is sensing.

[0206] In some embodiments, in the case that the number M of function types is greater than the number N of carriers configured by the network device, the N carriers can only support N function types of the M function types.

[0207] In some embodiments, in the case that the number M of function types is less than the number N of carriers configured by the network device, M carriers of the N carriers can respectively support each of the M function types, and the function types of the carriers other than the M carriers can be indicated by the network device in other manners or determined based on a predefined rule.

[0208] FIG. 4D is a schematic diagram of function types of another carrier, according to an embodiment of the present disclosure.

[0209] For example, the member carriers with the same carrier number correspond to different function types, and the member carriers with different numbers can correspond to one function type. For example, for the member carriers numbered 0 to N1+N2+N3, the member carriers numbered 0 to N1 can correspond to the same function type, the member carriers numbered N1+1 to N1+N2 can correspond to the same function type, and the member carriers numbered N1+N2+1 to N1+N2+N3 can correspond to the same function type.

[0210] For example, the function types include IC, HRLLC, UC, AI, ISAC, IoT, duplex, NES, sensing, anchor carrier, etc. For example, the number of carriers configured by the network device is 7, which are carrier#0, carrier#1, carrier#2, carrier#3, carrier#4, carrier#5, and carrier#6.

[0211] As shown in FIG. 4D, the function types of carrier#0 and carrier#1 are anchor carriers, the function types of carrier#2 and carrier#3 are IC, the function type of carrier#4 is HRLLC, the function type of carrier#5 is AI, and the function type of carrier#6 is sensing.

[0212] The communication method related to the embodiments of the present disclosure can include at least one of step S201 to step S202. For example, step S201 can be implemented as an independent embodiment, step S202 can be implemented as an independent embodiment, and step S201+S202 can be implemented as an independent embodiment, but is not limited thereto.

[0213] In some embodiments, steps S201 and S202 can be exchanged in order or executed simultaneously.

[0214] In some embodiments, step S201 is optional, and one or more of the steps can be omitted or replaced in different embodiments.

[0215] In some embodiments, step S202 is optional, and one or more of the steps can be omitted or replaced in different embodiments.

[0216] In some embodiments, other optional implementations described before or after the description of Figure 2 can be referred to.

[0248] The technical solutions of the present disclosure are further exemplarily described through several embodiments as follows:

[0249] Embodiment 1:

[0250] In the embodiment, the carriers in the wireless communication system have different types. The method in the embodiment does not limit the definition of the type of the carrier function. For example, the member carriers can be divided into types from the perspective of services and / or functions. For example, from the perspective of the type of service carried by the carrier, the carriers can be divided into carriers supporting IC, carriers supporting HRLLC, carriers supporting UC, and the like. Of course, the foregoing service types are only illustrative, and the method of the patent application does not exclude defining the carrier according to other types of services. For example, from the perspective of the function supported by the carrier, the carriers can be divided into carriers supporting AI functions, carriers supporting ISAC functions, carriers supporting IoT functions, carriers supporting duplex, carriers supporting NES technology, carriers supporting initial access operations, and the like. Of course, the foregoing function types are only illustrative, and the method of the patent application does not exclude defining the carrier according to other types of functions.

[0251] In the embodiment, the transmission technologies supported by the different types of carriers are different. For example, at least one of the frame structure, signals, and channels supported on the different types of carriers is different. In the embodiment, the determination manner of the frame structure, signals, and channels is not limited. For example, the frame structure is pre-configured or pre-defined; the signals and channels are signals or channels with specific definitions; and the signals and channels are signals and channels with corresponding characteristics, such as patterns, periods, resource allocations, and the like.

[0252] In the embodiment, for example, the network device sends explicit configuration information about the type of the carrier to the terminal, so as to inform the terminal of the type of each member carrier. Correspondingly, the network device determines the type of each member carrier and the transmission and reception behavior on the each member carrier according to the explicit configuration information. In the embodiment, the type of the carrier is defined at least according to one of the foregoing functions or the foregoing service types. As described above, the terminal determines that the one carrier supports at least one function or service based on the explicit indication information of the network device.

[0253] In the embodiment, the transmission and reception behavior of the terminal on the carrier of a specific type includes, but is not limited to, at least one of the transmission behavior, the reception behavior, and the measurement behavior. For example, the uplink channel or signal supported by the terminal is different, the downlink channel or signal supported by the terminal is different, the transmission behavior of the uplink channel or signal supported by the terminal is different, the reception behavior of the downlink channel or signal supported by the terminal is different, and the measurement behavior of the terminal is different.

[0254] In the embodiment, the channel, manner, and the like carrying the indication information of the type of the carrier are not limited. For example, if there are N different types of carrier types that need to be indicated in the system, the network device indicates by ceil(log2(N)) bits.

[0255] Exemplarily, the network device configures multiple carriers for the terminal and indicates respective carrier types. For example, an anchor carrier is a carrier accessed and camped by the terminal; a sensing carrier is a carrier used for sensing or supporting sensing, and has a sensing-specific structure; an AI carrier is a carrier used for supporting AI-specific services, data interaction, model interaction, etc.; an NES carrier is a carrier supporting network skill technology; an IC carrier is a carrier supporting immersive communication services, used to provide extreme transmission rate and user experience; and an HRLLC carrier is a carrier supporting high reliability and low latency services.

[0256] Embodiment 2

[0257] In this embodiment, the carriers in the wireless communication system have different types. The method in this embodiment does not limit the definition of carrier function types. Exemplarily, the member carriers can be divided into types from the perspective of services and / or functions.

If there are M types of carriers, and M>N, the configured carriers only support N types.

[0279] For example, the system defines IC carriers, HRLLC carriers, UC carriers, AI carriers, ISAC carriers, IoT carriers, duplex carriers, NES carriers, and anchor carriers. For example, the network device configures four carriers for the terminal. The types of the four carriers are as follows. Of course, the order of different carrier types in the embodiment is not limited.
