[0040] In addition to terminal devices, the communication system may also include one or more network devices. In this embodiment, the network device can be a device for communicating with the terminal device; this network device may also be referred to as an access network device or a radio access network device. For example, the network device may be a base station. In this embodiment, the network device may refer to an access network (RAN) node (or device) that connects the terminal device to the wireless network. Access network equipment can broadly encompass various names listed below, or be interchangeable with them, such as: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), master MeNB, secondary SeNB, multi-mode radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. Base stations can be macro base stations, micro base stations, relay nodes, donor nodes, or similar entities, or combinations thereof.

The cell can be the cell corresponding to the network device (e.g., a base station). The cell can belong to a macro base station or to a base station corresponding to a small cell. The small cell can include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

The network device 110 can provide communication coverage for a specific geographical area and can communicate with terminal devices located within that coverage area.

[0046] Figure 1 illustrates an exemplary network device and two terminal devices. In some embodiments of this application, the communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area. This application does not limit this aspect.

[0047] In some embodiments of this application, the wireless communication system shown in FIG1 may also include other network entities such as a mobility management entity (MME) and an access and mobility management function (AMF), but this application does not limit this.

[0048] It should be understood that devices with communication functions in the network / system of this application embodiment can be referred to as communication devices. Taking the communication system 100 shown in FIG1 as an example, the communication device may include a network device 110 and a terminal device 120 with communication functions.

The communication device may also include other devices in the communication system 100, such as network controllers, mobility management entities, and other network entities, which are not limited in this application embodiment. The following first introduces some concepts involved in the embodiments of this application.

[0049] Spectrum Aggregation

[0050] In communication systems, spectrum usage is based on frequency bands, which are often defined according to the actual spectrum used by network operators. Specifically, frequency bands are defined based on actual needs, but the actual spectrum allocation often differs slightly between different networks or regions. Therefore, under current definition methods, they are generally defined as different frequency bands. This results in a lack of planning in existing frequency band allocation, with many overlapping spectra and a large number of frequency bands. For example, Figure 2 shows a schematic diagram of frequency band definitions and spectrum relationships in related technologies. As shown in Figure 2, a large number of overlapping or partially overlapping frequency bands are defined in the spectrum from approximately 1.5 GHz to 2 GHz, leading to a sharp increase in the number of frequency band combinations. This significantly increases the complexity of terminal device implementation.

[0051] Reporting of terminal capability information

[0052] Currently, when terminal devices operate on a single carrier, they report terminal capability information according to the frequency band. For different carriers on the same frequency band, their capability information is the same when operating in single-carrier mode. For example, Figure 3 shows a schematic diagram of two carriers within the same frequency band. As shown in Figure 3, CC1 and CC2 are two carriers on Band X. In the current terminal capability information reporting method, the capabilities of these two carriers need to be consistent.

[0053] Carrier aggregation

[0054] Referring again to Figure 3, when using the two carriers shown in Figure 3 together, carrier aggregation, or band combination, is required. Typically, these two carriers need their own corresponding control and synchronization information. Transmitting this information consumes certain radio resources, so the actual result is that although the carrier bandwidth increases, the actual spectral efficiency decreases.

[0055] Network signaling and out-of-band protection

[0056] Currently, base stations use network signaling (NS) to indicate the out-of-band spectrum that terminal equipment needs to protect. This NS signaling is usually per band. As shown in Tables 1 and 2 below, NS_03 is used to identify the additional spectrum radiation requirements that terminal equipment needs to meet. These requirements are located in section 6.5.2.3.3, and this network signaling applies to frequency bands such as n2, n25, n66, n70, and n86.

[0057] Table 1

[0058] Table 2

[0059] As mentioned earlier when introducing spectrum aggregation, current spectrum usage methods define a large number of overlapping or partially overlapping frequency bands, resulting in a large number of bands and excessive spectrum fragmentation. This significantly increases the complexity of terminal device implementation. Therefore, how to avoid excessive spectrum fragmentation while ensuring the needs of different networks, thereby reducing the complexity of terminal device implementation, is the problem that this application aims to solve.

[0060] To address the aforementioned issues, in this embodiment of the application, the terminal device communicates with the network device through a portion of the frequency band (i.e., the first frequency portion or the second frequency portion in this embodiment of the application), thereby reducing the number of frequency bands divided in the spectrum, or in other words, avoiding excessive fragmentation of the spectrum, which in turn helps to reduce the complexity of the terminal device implementation.

[0061] The embodiments of this application will be described in detail below.

[0062] Figure 4 is a schematic flowchart of the communication method provided in an embodiment of this application. Referring to Figure 4, in step S410, the terminal device communicates with the network device in the first frequency portion and / or the second frequency portion of the first frequency band. Correspondingly, the network device communicates with the terminal device in the first frequency portion and / or the second frequency portion of the first frequency band.

[0063] As previously mentioned, based on the spectrum allocation methods in related technologies, terminal devices communicate with network devices within a frequency band. Unlike the solutions in related technologies, the embodiments of this application communicate with network devices through a portion of the frequency band (i.e., a first frequency portion or a second frequency portion), thereby reducing the number of frequency bands divided in the spectrum, or in other words, avoiding fragmented spectrum, and thus helping to reduce the complexity of terminal device implementation.

[0064] The frequency portions mentioned above can correspond to carriers, BWPs, or other frequency resource-related units. In some implementations, the first frequency portion can correspond to a carrier or a BWP within a first frequency band, and / or, the second frequency portion can correspond to a carrier or a BWP within the first frequency band. For example, the first frequency portion corresponds to a carrier within the first frequency band, and the second frequency portion corresponds to a carrier within the first frequency band. Or, for instance, the first frequency portion corresponds to a BWP within the first frequency band, and the second frequency portion corresponds to a BWP within the first frequency band.

[0065] The first frequency portion and the second frequency portion can each correspond to a frequency band in the related technology. Alternatively, two frequency bands in the related technology can be merged (or aggregated) into a new frequency band (i.e., the first frequency band), and then these two frequency bands become part of this new frequency band (such as a carrier or BWP). It should be understood that multiple (more than two) frequency bands in the related technology can also be merged into a new frequency band; this application does not specifically limit this. For example, overlapping frequency bands (including partial and complete overlap) can be merged into a new frequency band. Similarly, non-overlapping frequency bands with small intervals can be merged into a new frequency band. Furthermore, overlapping frequency bands (including partial and complete overlap) and those with small intervals can be merged into a new frequency band.

[0066] For example, Figure 5 shows a schematic diagram of merging two independent frequency bands into a carrier in a new frequency band. As shown in Figure 5, Band A and Band B are two adjacent frequency bands, which are now merged into a new frequency band Band X, becoming two carriers CC1 and CC2 in Band X.

[0067] As mentioned earlier when discussing the reporting of terminal capability information, in single-carrier operating mode, the terminal capabilities corresponding to different carriers within a frequency band are the same. Therefore, terminal capability information in related technologies is reported according to frequency bands. The following section provides two examples of terminal capabilities reported according to frequency bands in related technologies.

[0068] Terminal Capability 1: Power Class. This parameter specifies the maximum transmit power of a terminal device. There are multiple power classes, and different power classes may be required for different frequency bands or scenarios. For example, a power class of 2 (PC2) has a maximum transmit power of 26dBm (approximately 400mW). PC2 is suitable for low-frequency bands (such as Sub-1GHz), improving uplink signal coverage through high power, making it suitable for remote areas or wide-area scenarios. On the other hand, a power class of 3 (PC3) has a maximum power of 23dBm (approximately 200mW). PC3 is suitable for high-frequency bands (such as above 1GHz), ensuring coverage while reducing power consumption and heat dissipation.

[0069] Terminal capability two: Multiple-input multiple-output (MIMO) layer. This refers to the number of independent data streams used for simultaneous data transmission in a MIMO communication system. Each "layer" represents an independent data stream. For example, MIMO layer 2 indicates that the terminal device supports the simultaneous transmission of two independent data streams. Similarly, MIMO layer 3 indicates that the terminal device supports the simultaneous transmission of three independent data streams.

[0070] For example, referring to Figure 5, in related technologies, Band A reports a power level of PC2, and Band B reports a power level of PC3. In the embodiments of this application, different frequency portions of the first frequency band may correspond to different terminal capabilities or the same terminal capabilities. Therefore, the embodiments of this application need to consider how to distinguish the terminal capabilities corresponding to different frequency portions of the first frequency band.

[0071] In some implementations, the terminal device can send first information to the network device, and the network device receives the first information accordingly. The first information is used to indicate the capabilities corresponding to the first frequency portion and / or the second frequency portion. That is, the different terminal capabilities corresponding to different frequency portions can be reported to the network device to ensure that the network device can correctly distinguish them.

[0072] It should be understood that "the terminal device communicates with the network device in the first frequency part and / or the second frequency part of the first frequency band" in step S410 can be replaced with "the terminal device sends first information to the network device in the first frequency part and / or the second frequency part of the first frequency band".

[0073] For example, the terminal device can report the terminal capabilities corresponding to each carrier and / or each BWP in the first frequency band in the first information. That is, it can report in one or more of the following ways: per CC per Band, per BWP per Band, per BWP per CC, or per BWP per CC. In this way, it can be ensured that when a spectrum is changed from a frequency band to a carrier or BWP, the terminal capabilities can still be reported, distinguished, and controlled separately for each carrier or BWP in the new frequency band.

[0074] Currently, many terminal capabilities of terminal devices are reported according to frequency bands. Accordingly, the terminal capabilities reported based on the first information can include a variety of types. In some implementations, the first information can be used to indicate one or more of the following: power level-related capabilities corresponding to the first frequency portion and / or the second frequency portion; and MIMO-related capabilities corresponding to the first frequency portion and / or the second frequency portion.

[0075] For example, as shown in Figure 5, assuming the terminal device reports a power level of PC2 in Band A, then according to the power level reporting mechanism in related technologies, the terminal device will also report a power level of PC2 when each carrier in Band A is operating independently; similarly, assuming it reports a power level of PC3 in Band B, then according to the power level reporting mechanism in related technologies, the terminal device will also report a power level of PC3 when each carrier in Band B is operating independently; when Band A and Band B are combined into a new Band X, the terminal device can report terminal capabilities of power levels PC2 and PC3 for CC1 and CC2 in Band X, respectively.

[0076] For example, as shown in Figure 5, assuming the terminal device reports MIMO layer 2 in Band A, then according to the MIMO layer reporting mechanism in related technologies, the terminal device will also report MIMO layer 2 when each carrier in Band A is operating independently. Similarly, assuming the terminal device reports MIMO layer 3 in Band B, then according to the MIMO layer reporting mechanism in related technologies, the terminal device will also report MIMO layer 3 when each carrier in Band B is operating independently. When Band A and Band B are combined into carriers within a new Band X, the terminal device can report terminal capabilities of MIMO layer 2 and MIMO layer 3 for CC1 and CC2 in Band X, respectively.

[0077] In some implementations, the first frequency band can correspond to a single radio frequency (RF) link (or RF front-end link) of the terminal device. That is, the first and second frequency bands correspond to the same RF link. The advantages of this RF link design will be illustrated below with examples from Figures 6A and 6B.

[0078] For example, Figures 6A and 6B show comparative schematic diagrams of the RF front-end of the terminal device in related technologies and embodiments of this application, respectively. When the terminal device simultaneously supports Band A and Band B, in related technologies, as shown in Figure 6A, Band A and Band B correspond to two RF front-end links of the terminal device, i.e., one RF front-end link corresponds to Band A and the other corresponds to Band B. This design requires a duplexer (or combiner) in the RF front-end to achieve simultaneous operation of Band A and Band B. In the embodiments of this application, as shown in Figure 6B, Band X (i.e., a new Band obtained by merging Band A and Band B) corresponds to one RF front-end link of the terminal device, i.e., one RF front-end link corresponds to both Band A and Band B. This design reduces the complexity of the RF front-end, for example, by eliminating complex front-end devices such as duplexers, which to some extent simplifies the design of the RF front-end, thereby improving transmit power or receive sensitivity.

[0079] Alternatively, the first frequency band can correspond to two radio frequency links of the terminal device. That is, the first frequency part and the second frequency part can each correspond to one radio frequency link.

[0080] As previously mentioned, in related technologies, network devices can use network signaling (NS) to instruct terminal devices on frequency band-based transmission requirements (such as out-of-band spectrum requiring protection). In this embodiment, the network device can also use signaling to instruct terminal devices on frequency band-based transmission requirements, and can also use signaling to instruct terminal devices on transmission requirements based on a portion of the frequency band (such as in-band spectrum requiring protection).

[0081] In some implementations, as shown in Figure 7, in step S710, the network device sends a first signaling message to the terminal device, and the terminal device receives the first signaling message accordingly. The first signaling message is used to indicate the transmission requirements corresponding to the first frequency portion and / or the second frequency portion. This transmission requirement can be a protection indication or protection requirement for a first frequency range of the first frequency band. For example, the first frequency range can be located between the first frequency portion and the second frequency portion, or in other words, the first frequency range is the frequency range (or intermediate spectrum) between the first frequency portion and the second frequency portion. Alternatively, the first frequency range can be the frequency ranges on both sides of the first frequency portion and the second frequency portion.

[0082] It should be understood that "first frequency range located between first frequency portion and second frequency portion" can be interpreted as the frequency range between the first frequency portion and the second frequency portion, without overlapping with either. For example, the starting frequency of the first frequency range can be greater than or equal to the ending frequency of the first frequency portion, and the ending frequency of the first frequency range can be less than or equal to the starting frequency of the second frequency portion; or, the starting frequency of the first frequency range can be greater than or equal to the ending frequency of the second frequency portion, and the ending frequency of the first frequency range can be less than or equal to the starting frequency of the first frequency portion.

[0083] For example, as shown in Figure 8, taking CC1 as the first frequency part and CC2 as the second frequency part, the intermediate spectrum located between CC1 and CC2 can be understood as the starting frequency of the intermediate spectrum being greater than or equal to the ending frequency of CC1, and the ending frequency of the intermediate frequency being less than or equal to the starting frequency of CC2.

[0084] In other words, compared to the frequency band-based protection requirements in related technologies (which use network signaling NS values ​​to indicate the spectrum to be protected and the corresponding requirements for the terminal device), the embodiments of this application can introduce protection indications for a specific frequency range within the first frequency band (such as a first frequency portion or a second frequency portion). For example, additional protection requirements can be imposed on the first frequency range described above. This helps to avoid interference with services corresponding to a specific frequency range within the frequency band. The reason is that in some cases, a specific frequency range within the first frequency band may not be a frequency range used for mobile communication, but rather a frequency range used for other services. For example, this frequency range may be allocated specifically for services such as radar detection and cannot be used as a communication carrier. By setting protection requirements for this frequency range, interference with signals of other services (such as radar detection failure) can be prevented.

[0085] For example, protection requirements based on the carrier wave for a first frequency range within the first frequency band can be introduced. Alternatively, protection requirements based on the BWP (Browser-Wide Plateau) within the carrier wave for a first frequency range within the first frequency band can be introduced.

[0086] For example, as shown in Figure 8, a protection requirement for the intermediate spectrum in Band X based on the carrier (CC1 or CC2 in Band X) can be introduced, and the indication of such protection requirement can be understood as per CC per Band.

[0087] Alternatively, as shown in Figure 9, a protection requirement for the intermediate spectrum in Band X can be introduced based on the BWP (BWP1 or BWP2 in CC1) within the carrier. This protection requirement can be understood as per BWP per CC or per BWP per Band or per BWP per CC per Band.

[0088] Referring again to Figure 7, in step S720, the terminal device adjusts the uplink transmit power to meet the transmit requirements indicated by the first signaling.

[0089] Furthermore, how terminal devices support frequency band combinations is also an issue that needs to be considered in the embodiments of this application.

[0090] In some implementations, the terminal device can send second information to the network device, and the network device receives the second information accordingly. The second information is used to indicate a combination of a first frequency band and a second frequency band supported by the terminal device.

[0091] The second frequency band mentioned above can be a frequency band determined by the fusion of multiple frequency bands in related technologies, or it can be a frequency band in related technologies. For example, as shown in Figure 10, Band A, Band B, Band C, and Band D in related technologies are aggregated into CC1 and CC2 in the new Band X, and CC3 and CC4 in the new Band Y, respectively; as shown in Figure 11, Band A, Band B, Band C, and Band D in related technologies are aggregated into BWP1 and BWP2 in the new Band X, and BWP3 and BWP4 in the new Band Y, respectively. The second information can indicate that the terminal device supports the combination of Band X and Band Y.

[0092] Furthermore, the second information can be used to indicate that the terminal device supports a combination of a first frequency portion of the first frequency band and the second frequency band. That is, the terminal device supports a combination of a portion of the first frequency band and any portion of the second frequency band. For example, if the first frequency portion is a carrier of the first frequency band, then the second information can indicate that the terminal device supports a combination of a carrier of the first frequency band and any carrier of the second frequency band. For example, as shown in FIG10, the second information can indicate that the terminal device supports the combination of CC1 and Band Y in Band X, that is, the terminal device supports the combination of CC1+CC3 and CC1+CC4. As another example, if the first frequency portion is a BWP of the first frequency band, then the second information can indicate that the terminal device supports a combination of a BWP of the first frequency band and any BWP of the second frequency band. For example, as shown in FIG11, the second information can indicate that the terminal device supports the combination of BWP1 and Band Y in Band X, that is, the terminal device supports the combination of BWP1+BWP3 and BWP1+BWP4.

[0093] Alternatively, the second information can also be used to indicate that the terminal device supports a combination of a first frequency portion of the first frequency band and a third frequency portion of the second frequency band. Here, the third frequency portion can be a carrier or BWP of the second frequency band; that is, the terminal device supports a combination of a portion of the first frequency band and a portion of the second frequency band. For example, if the first frequency portion is a carrier of the first frequency band and the third frequency portion is a carrier of the second frequency band, then the second information can indicate that the terminal device supports a combination of a carrier of the first frequency band and a carrier of the second frequency band. For example, as shown in FIG10, the second information can indicate that the terminal device supports a combination of CC1 in Band X and CC3 in Band Y. As another example, if the first frequency portion is a BWP of the first frequency band and the third frequency portion is a BWP of the second frequency band, then the second information can indicate that the terminal device supports a combination of a BWP of the first frequency band and a BWP of the second frequency band. For example, as shown in FIG11, the second information can indicate that the terminal device supports a combination of BWP1 in Band X and BWP3 in Band Y.

[0094] Furthermore, when the second information indicates that the terminal device supports a BWP combination, the second information can also indicate the combination of carriers corresponding to the BWP. For example, as shown in Figure 11, the second information can indicate that the terminal device supports the combination of CC1 in Band X and CC3 in Band Y. Further, the second information also indicates that the terminal device supports the combination of BWP1 in CC1 and BWP3 in CC3.

[0095] Taking Figure 10 as an example, when performing frequency band combination: the frequency band combination of Band A + Band B in related technologies will become intra-band carrier aggregation (intra-band CA) within Band X; the frequency band combination of Band C + Band D in related technologies will become intra-band CA within Band Y; for combinations that cross new frequency bands (Band X or Band Y), such as Band A + Band C, Band A + Band D, Band B + Band C, and Band B + Band D, since the frequency range of the new frequency band after aggregation is larger, the terminal device may only support the aggregation of some carriers (such as CC1 + CC2) and not the aggregation of other carriers. That is to say, in the embodiments of this application, the terminal device may support a combination of a part of the new frequency band combination (or any combination of any part of the new frequency band combination). Therefore, by sending the second information described above to the network device, the network device can confirm the specific combination supported by the terminal device (see the description of the content indicated by the second information above).

[0096] In some implementations, the second information may also indicate a specific frequency range supported by the terminal device. For example, if the second information indicates that the terminal device supports a combination of a first frequency portion of a first frequency band and a third frequency portion of a second frequency band, then the second information may also indicate one or more of the frequency ranges of the first frequency portion and the frequency range of the third frequency portion.

[0097] In some implementations, the second information may further include first indication information. The first indication information is used to indicate a combination of a first frequency band and a second frequency band supported by the terminal device, or to indicate a combination of a first carrier and a second carrier supported by the terminal device, or to indicate a combination of a first BWP and a second BWP supported by the terminal device, or to indicate the start and / or end frequencies of the frequency range corresponding to the carrier and / or BWP supported by the terminal device.

[0098] Alternatively, the first indication information can also be used to: when the first indication information indicates a combination of a first frequency band and a second frequency band supported by the terminal device, the first indication information can also indicate a combination of a first carrier and a second carrier in the combination of the first frequency band and the second frequency band supported by the terminal device; further, when the first indication information indicates a combination of a first frequency band and a second frequency band and a combination of a first carrier and a second carrier supported by the terminal device, the first indication information can also indicate the start frequency and / or end frequency of the frequency range corresponding to the carrier supported by the terminal device; or, when the first indication information indicates a combination of a first frequency band and a second frequency band and a combination of a first carrier and a second carrier supported by the terminal device, the first indication information can also indicate a combination of a first BWP and a second BWP in the combination of the first carrier and the second carrier supported by the terminal device; or, when the first indication information indicates a combination of a first frequency band and a second frequency band, a combination of a first carrier and a second carrier, and a combination of a first BWP and a second BWP supported by the terminal device, the first indication information can also indicate the start frequency and / or end frequency of the frequency range corresponding to the carrier and / or BWP supported by the terminal device.

[0099] Alternatively, in some other implementations, the second information may further include second indication information and third indication information. The second and third indication information can be used for: the second indication information instructing the terminal device to support a first frequency band, and the third indication information instructing the terminal device to support a second frequency band; further, the indication results of the second and third indication information can be used to determine that the frequency band combination supported by the terminal device is a combination of the first and second frequency bands; or, the second indication information instructing the terminal device to support a first carrier, and the third indication information instructing the terminal device to support a second carrier; further, the indication results of the second and third indication information can be used to determine that the carrier combination supported by the terminal device is a combination of the first and second carriers; or, the second indication information instructing the terminal device to support a first BWP, and the third indication information instructing the terminal device to support a second BWP; further, the indication results of the second and third indication information can be used to determine that the BWP combination supported by the terminal device is a combination of the first and second BWPs.

[0100] Alternatively, the second and third indication information can also be used to: when the second indication information indicates that the terminal device supports the first frequency band and the third indication information indicates that the terminal device supports the second frequency band, the second indication information can also indicate the first carrier in the first frequency band supported by the terminal device, and the third indication information can also indicate that the terminal device supports the second carrier in the second frequency band, and the combination of carriers supported by the terminal device can be determined as a combination of the first carrier and the second carrier based on the indication results of the second and third indication information; furthermore, the second indication information can also indicate the first BWP in the first carrier supported by the terminal device, and the third indication information can also indicate the second BWP of the second carrier supported by the terminal device, and the combination of BWPs supported by the terminal device can be determined as a combination of the first BWP and the second BWP based on the indication results of the second and third indication information.

[0101] It should be understood that the above-mentioned combinations of the second information indication can be predefined, and the frequency range of the second information indication can be predefined or indicated by the terminal device. This application embodiment does not specifically limit this.

[0102] For ease of understanding, the following describes in detail, with reference to Figures 10 and 11, four implementation methods of the second information in the embodiments of this application.

[0103] Implementation Method 1: The second information indicates the frequency band combination and carrier combination supported by the terminal device.

[0104] The carrier combinations supported by the terminal device can be predefined, such as the combinations CC1+CC3, CC1+CC4, CC2+CC3, and CC2+CC4 in Figure 10. The frequency range of each carrier can also be predefined. If the terminal device reports a supported frequency band combination of Band X and Band Y via the second information, it will further report the supported carrier combinations as well, for example, reporting a supported carrier combination of CC1+CC3 via the second information. Therefore, the second information can include the following:

[0105] In implementation method 1, the band combination can be determined to be X+Y by the indication of the band combination indication information in the second information; the CC combination can be determined to be CC1+CC3 by the indication of the CC combination indication information in the second information.

[0106] Implementation Method 2: The second information indicates the frequency band combination, carrier combination, and frequency range supported by the terminal device.

[0107] The frequency range of each carrier in the carrier combination supported by the terminal device can be indicated by the terminal device. For example, in Figure 10, the frequency range of CC1 is from f10 to f11, and the frequency range of CC3 is from f30 to f31. If the terminal device reports supported frequency band combinations of Band X and Band Y via the second information, the supported carrier combination is the combination of CC1+CC3. ​​The second information may include the following:

[0108] In implementation method 2, the band combination can be determined to be X+Y by the band combination indication information in the second information; the CC combination can be determined to be CC1+CC3 by the CC combination indication information in the second information; and CC1_start, CC1_end, CC3_start, and CC3_end can be determined by the CC_start and CC_end indication information in the second information.

[0109] Implementation Method 3: The second information indicates the frequency band combination and BWP combination supported by the terminal device (which may also include carrier combination).

[0110] The BWP combinations supported by the terminal device can be predefined, such as the combinations of BWP1+BWP3, BWP1+BWP4, BWP2+BWP3, and BWP2+BWP4 in Figure 11. If the terminal device reports a supported frequency band combination of Band X and Band Y via the second information, it will further report the supported BWP combinations as well, for example, reporting a supported BWP combination of BWP1+BWP3 via the second information. The second information may include the following:

[0111] Alternatively, the second information may further indicate the combination of carriers corresponding to the BWP, that is, the second information may include:

[0112] In implementation method 3, the band combination can be determined to be X+Y by the indication of the band combination indication information in the second information; the CC combination can be determined to be CC1+CC3 by the indication of the CC combination indication information in the second information; and the BWP combination can be determined to be BWP1+BWP3 by the indication of the BWP combination indication information in the second information.

[0113] In implementation method 3, when the second information only indicates the frequency band combination and carrier combination supported by the terminal device, it can be called a two-level reporting method. When the second information indicates the frequency band combination, carrier combination and BWP combination supported by the terminal device, it can be called a three-level reporting method.

[0114] Implementation Method 4: The second information indicates the frequency band combination, BWP combination, and frequency range supported by the terminal device (which may also include carrier combination).

[0115] The frequency range of each BWP in the BWP combination supported by the terminal device can be indicated by the terminal device. For example, in Figure 11, the range of BWP1 is from f13 to f14, and the range of BWP3 is from f33 to f34. If the terminal device reports a supported frequency band combination of Band X and Band Y via the second information, the supported BWP combination is the combination of BWP1 and BWP3. The second information may include the following:

[0116] Alternatively, the second information may further indicate the combination of carriers corresponding to the BWP and the frequency range of the carriers; that is, the second information may include:

[0117] In implementation method 4, the band combination can be determined to be X+Y by the band combination indication information in the second information; the CC combination can be determined to be CC1+CC3 by the CC combination indication information in the second information; the BWP combination can be determined to be BWP1+BWP3 by the BWP combination indication information in the second information; CC1_start, CC1_end, CC3_start, and CC3_end can be determined by the CC_start and CC_end indication information in the second information; and BWP1_start, BWP1_end, BWP3_start, and BWP3_end can be determined by the BWP_start and BWP_end indication information in the second information.

[0118] In implementation method 4, when the second information only indicates the frequency band combination, BWP combination and frequency range supported by the terminal device, it can be called a level 2 reporting method. When the second information indicates the frequency band combination, carrier combination, BWP combination and frequency range supported by the terminal device, it can be called a level 3 reporting method.
