Description

The present application relates to the field of communication technology, and in particular to methods and related devices for reporting bandwidth information.

In a communication system, a terminal device needs to report its capability information to a base station and a core network after accessing a network. For example, the network device sends a terminal device capability query message to the terminal device, and the terminal device capability query message includes a RAT type indication of some radio access technology (RAT) that needs to be requested. . Similarly, the terminal device transmits terminal device capability information to the network device, and the terminal device capability information includes relevant terminal device capability information in these radio access technologies.

For example, related function information includes band combination (BC) information. If the RAT type indicated by the RAT type indication includes New Radio NR, the capability information of the terminal device includes New radio standalone band combination (NR SA BC) and New radio dual connection band combination (New radio Dual Connectivity band combination, NR-DC BC). If the RAT type indicated by the RAT type indication includes Evolved-UMTS Terrestrial Radio Access - New Radio (Evolved-UMTS Terrestrial Radio Access, E-UTRA-NR), the capability information of the terminal device is Evolved Universal Mobile Communication System Terrestrial Radio Access New Radio-Dual Connectivity (E-UTRA-NR Dual Connectivity, EN-D) BC and New Radio Evolved Universal Mobile Communication System Terrestrial Radio Access-Dual Connectivity (NR-E-UTRA Dual Connectivity) , NE-DC) BC, and the like. In order to reduce the overhead required to report the terminal device's capability information, for all band combinations that are determined based on the RAT type indication and supported by the terminal device, the terminal device may use the same band combination as one of the band combinations. Remove functional fallback band combinations and do not report band combinations. As an example, band combination 1 and band combination 2 are used. Band combination 1 has the same function as band combination 2 and is a band combination obtained after band combination 2 is fallen back. In this case, the terminal device does not report band combination 1.

However, band combination 1 and band combination 2 are assumed to correspond to different RAT types, eg, RAT type 1 and RAT type 2. In this case, if the terminal device does not report band combination 1, when determining the band combination corresponding to RAT type 1, the network device may use the band corresponding to another RAT type to obtain band combination 1. Combinations, eg , band combination 2 corresponding to RAT type 2, also need to be considered. This results in a relatively large processing load on the network device.

Embodiments of the present application provide methods and associated devices for reporting bandwidth information to help reduce the processing load of network devices.

According to a first aspect, the present application provides a method for reporting band information. In this method, the terminal device may determine a first set of band combinations transmitted by the terminal device and report the first set of band combinations.

Therefore, when determining the band combinations corresponding to the RAT type, the network device selects the band combinations corresponding to the RAT type that are in the first band combination set to obtain all band combinations corresponding to the RAT type. you just have to consider. This reduces the processing load on the network device.

To facilitate understanding of the embodiments disclosed in the present application, some concepts in the embodiments of the present application are first explained. These concepts include, but are not limited to:

Terminal Device Capability Query Message: The Terminal Device Capability Query message is used to request a terminal device to transmit one or more radio access capabilities of the terminal device on one or more RATs. The RAT type indicated by the RAT type indication in the terminal device capabilities query message may include multiple RAT types, eg, 4G, 5G, future 6G, or another standard. The RAT type indicated by the RAT type indication may further include multiple RATs in which the terminal device operates simultaneously, eg, EN-DC and NE-DC.

The terminal device capability query message may further include capability filter parameters, which are used to indicate the scope of the requested terminal device capability information, the parameters of the requested terminal device capability information, and so on. Functional filter parameters may include band information and the like. The band information is used to indicate that the terminal device requests band combinations that it supports, and may indicate that it requests all band combinations or band combinations within a specified range.

First band combination set and second band combination set: the second band combination set is determined by the terminal device based on the capability inquiry message of the terminal device and is a set containing band combinations supported by the terminal device. . The second set of band combinations can be all band combinations or band combinations within a specified range. This is not limited to the embodiments of the present application. The first set of band combinations is a set containing band combinations to be transmitted determined by the terminal device. In other words, the band combinations of the first band combination set are also band combinations supported by the terminal device. However, the first band combination set is a subset of the second band combination set. In this way, the amount of explicitly reported band combinations can be reduced, thus reducing the overhead required for reporting.

Band combination: Band combination means that a terminal device can operate in one or more bands. That is, one band combination may correspond to one or more bands, eg, BC1 (band 1, band 2). A set of band combinations is a set including a plurality of band combinations, for example, a band combination set {BC1 (band 1, band 2); BC2 (band 3, band 4)}.

Fallback band combination: A fallback band combination is a band combination obtained by releasing at least one secondary cell, or an uplink configuration of at least one secondary cell, or a secondary cell group from a band combination. A secondary cell may be a secondary carrier and a secondary cell group may be a carrier corresponding to a secondary node.

For example, Table 1 shows band combinations obtained by releasing at least one secondary cell, or uplink configuration of at least one secondary cell, or secondary cell group from some large band combination. Note that L_band represents the LTE band and N_band represents the NR band.

In Table 1, any band (N_band1, N_band2) of NR SA BC1 can be used as a secondary cell. Therefore, the band combination obtained by releasing the uplink configuration of one secondary cell or one secondary cell from NR SA BC1 (N_band1, N_band2) is NR SA BC2 (N_band1) and NR SA BC3 (N_band2). be.

In Table 1, in NE-DC BC1 (L_band1, N_band3), N_band3 is the cell of the master node and L_band1 is the cell of the secondary node. You cannot release the master node, only secondary nodes. Therefore, the band combination obtained by releasing the secondary cell group is NR SA BC3 (N_band3).

In Table 1, in NE-DC BC2 (L_band1, L_band2, N_band4, N_band5), N_band4 and N_band5 are cells of the master base station, each N_band may be used as a secondary cell of the master node, and L_band is of the secondary node. cell (ie, secondary cell). Therefore, the band combination obtained by releasing one secondary cell, the uplink configuration of one secondary cell, or the secondary cell group from NE-DC BC3 (L_band1, L_band2, N_band4, N_band5) is NE-DC BC3 (L_band2, N_band4, N_band5), NE-DC BC4 (L_band1, N_band4, N_band5), NR SA BC5 (N_band4), NR SA BC6 (N_band5), and NR SA BC7 (N_band4, N_band5).

Band combinations corresponding to different RAT types may be contained in corresponding RAT containers. For example, a band combination included in an NR container is a band combination corresponding to NR. For example, the NR container includes a New radio standalone band combination (NR SA BC) and a New radio dual connection band combination (NR DC BC). The band combinations included in the MR-DC container are a band combination corresponding to NE-DC and a band combination corresponding to EN-DC. For example, the MR-DC container has EN-DC BC, NGEN-DC, and NE-DC Including BC. A band combination included in the EUTRA container is a band combination corresponding to LTE. For example, the EUTRA container contains LTE BC.

For example, for the band combinations shown in Table 1, NR SA BC1 (N_band1, N_band2), NR SA BC2 (N_band1), NR SA BC3 (N_band2), NR SA BC4 (N_band3), NR SA BC5 (N_band4, N_band5), NR SA BC6 (N_band4), and NR SA BC7 (N_band5) are band combinations contained in the NR container. NE-DC BC1 (L_band1, N_band3), NE-DC BC2 (L_band1, L_band2, N_band4, N_band5), NE-DC BC3 (L_band2, N_band4, N_band5), and NE-DC BC4 (L_band1, N_band4, N_band5) are - It is a band combination contained in the DC container.

To reduce the overhead required to report band information, currently fallback band combinations with the same functionality are not explicitly reported. A function may include, but is not limited to, at least one of the following function parameters. That is, packet data convergence protocol (PDCP) parameters of the terminal, radio link control (RLC) parameters of the terminal, medium access control (MAC) parameters of the terminal, physical ( Physical, PHY ) parameters, radio frequency (RF) parameters of the terminal, radio measurement management (RRM) parameters of the terminal, and the like. The same function means that the aforementioned function parameters of the band combination are the same as those of the band combination obtained after the band combination is fallbacked. This embodiment of the present application will be explained by using an example where the band combination obtained after fallback has the same functionality as the band combination obtained before fallback. If the band combination obtained after fallback has different features from the band combination obtained before fallback, the band combination obtained after fallback also needs to be reported explicitly.

For example, NR SA BC2 (N_band1) and NR SA BC3 (N_band2) are band combinations after NR SA BC1 (N_band1, N_band2) are fallbacked, and NR SA BC4 (N_band3) is NE-DC BC1 (L_band1 , N_band3) is the band combination after fallback, NE-DC BC3 (L_band2, N_band4, N_band5), NE-DC BC4 (L_band1, N_band4, N_band5), NR SA BC5 (N_band4, N_band5), NR SA BC6 (N_band4) and NR SA BC7 (N_band5) are the band combinations after NE-DC BC2 (L_band1, L_band2, N_band4, N_band5) are fallbacked. These band combinations obtained after fallback are assumed to have the same features, eg, the same feature parameters, as the band combinations to be fallbacked. In this case, those band combinations obtained after fallback will not be reported according to the current method for reporting band information. As shown in FIG. 4, the NR container reported by the terminal device does not include the band combinations within the dashed box, and the MR-DC container reported by the terminal device does not include the band combinations within the dashed box. . Further, band combination sets from terminal devices may be shown in FIG. The overhead of reporting band combination information in FIG. 5 is much less than that in FIG.

However, when the network device receives the band combination set shown in FIG. 5 and further determines the band combinations supported by the terminal device shown in FIG. 3, to obtain all the band combinations in the NR container: The network device is acquired after the band combination in the NR container is fallbacked and has the same functionality as the band combination, and the band combination in the MR-DC container is acquired after the band combination is fallbacked. Both band combinations within an NR container with the same functionality need to be considered. For example, the network device is in the MR-DC container, the band combination obtained after the NE-DC BC1 (L_band1, N_band3) is fallen back, i.e. NR SA BC4 (N_band3) added to the NR container, and NE-DC BC2 (L_band1, L_band2, N_band4, N_band5) is added to the band combinations obtained after fallback, namely the NR container (NR SA BC5 (N_band4, N_band5), NR SA BC6 (N_band4), and NR SA BC7 (N_band5), In addition, the network device may obtain the band combinations supported by the terminal device shown in FIG.

It can be understood that a network device needs to refer to band combinations corresponding to multiple RAT types in order to obtain all band combinations corresponding to one RAT type. This greatly increases the operating load of network devices.

To solve this problem, the present application provides a method of reporting bandwidth information to reduce the overhead required for reporting bandwidth information and reduce the operational load of network devices.

FIG. 6 is a schematic flow chart of a method for reporting band information, according to an embodiment of the present application. As shown in FIG. 6, the method for reporting band information includes the following steps.

201: The terminal device determines a first band combination set to be transmitted, the first band combination set includes a first band combination and a second band combination, the first band combination includes a second The first band combination and the second band combination correspond to different radio access technology types.

202: The terminal device sends the first band combination set to the network device.

203: The network device receives the first band combination set and determines a second band combination set supported by the terminal device based on the first band combination set.

In this embodiment of the present application, the terminal device determines the first band combination set transmitted by the terminal device based on the band combination set supported by the terminal device, i.e. the second band combination set.

In an optional implementation, the first band combination set is a subset of the second band combination set, and the second band combination set has a fallback with the same functionality as each band combination of the first band combination set. Also includes band combinations.

A protocol or signaling may be used to predefine or configure that the terminal device by default supports a fallback band combination that has the same functionality as each band combination of the first band combination set. In other words, the second band combination set includes both each band combination of the first band combination set and a fallback band combination having the same function as each band combination of the first band combination set. In an optional implementation, in this embodiment of the present application, terminal devices need not report all fallback band combinations or explicitly report all fallback band combinations, but the second In addition to large band combinations such as the band combination of , some of the fallback band combinations can also be reported. The first band combination set may include a first band combination and a second band combination, the first band combination being a fallback band combination having the same function as the second band combination, and the first The band combination and the second band combination correspond to different radio access technology types.

For example, in Table 1, a large BC such as NR SA BC1 (N_band1, N_band2), NE-DC BC1 (L_band1, N_band3), or NE-DC BC2 (L_band1, L_band2, N_band4, N_band5) is the second band combination. be. The band combination obtained after falling back the large BC corresponding to another radio access technology type, such as NR SA BC4 (N_band3) or NR SA BC5 (N_band4, N_band5), is the first band combination.

The second set of band combinations is assumed to contain all band combinations of Table 1. As shown in FIG. 3, in the second band combination set, the NR containers are NR SA BC1 (N_band1, N_band2), NR SA BC2 (N_band1), NR SA BC3 (N_band2), NR SA BC4 (N_band3), NR SA BC5 (N_band4, N_band5), NR SA BC6 (N_band4), and NR SA BC7 (N_band5), MR-DC containers are NE-DC BC1 (L_band1, N_band3), NE-DC BC2 (L_band1, L_band2 , N_band4, N_band5), NE-DC BC3 (L_band2, N_band4, N_band5), and NE-DC BC4 (L_band1, N_band4, N_band5). In this case, according to the method for reporting band information in this embodiment of the present application, NR SA BC4 (N_band3) is a fallback band combination with the same function as NE-DC BC1 (L_band1, N_band3) However, NR SA BC4 (N_band3) and NE-DC BC1 (L_band1, N_band3) correspond to different radio access technology types, so NR SA BC4 (N_band3) is the first band combination. Similarly, NR SA BC5(N_band4, N_band5) is the first band combination.

Therefore, as shown in FIG. 7, in the first band combination set, the NR container includes NR SA BC1 (N_band1, N_band2), NR SA BC4 (N_band3), and NR SA BC5 (N_band4, N_band5), and MR - DC container contains NE-DC BC1 (L_band1, N_band3) and NE-DC BC2 (L_band1, L_band2, N_band4, N_band5).

Similarly, the network device determining the second set of band combinations supported by the terminal device based on the first set of band combinations may be as follows. That is, the network device adds to the first band combination set a fallback band combination having the same function as each band combination of the first band combination set to obtain a second band combination set. It can be appreciated that in this embodiment of the present application, the quantity of band combinations in the first band combination set is less than the quantity of band combinations in the second band combination set. Therefore, compared to methods of reporting or transmitting all band combinations in the second set of band combinations, the method provided in this embodiment of the present application reduces the overhead required to report band information. can do. Furthermore, in this embodiment of the present application, the terminal device also explicitly reports the band combination of the type of the first band combination to the network device, so that when determining the fallback band combination to be added, the network device should only consider band combinations obtained after a larger band combination corresponding to the same RAT type is fallen back.

For example, as shown in FIG. 7, the network device uses the band combinations in the NR container, e.g., NR SA BC1 (N_band1, N_band2) and NR SA BC5, to obtain the band combinations in the NR container shown in FIG. We only have to consider the band combinations obtained after (N_band4, N_band5) are fallen back. Since the reported band combinations include NRSA BC2 (N_band3) and NR SA BC5 (N_band4, N_band5), the network device should select the band combination corresponding to MR-DC, i.e. NE-DC BC1 (L_band1, N_band3) and the band combinations obtained after NE-DC BC2 (L_band1, N_band4, N_band5) are fallen back . In other words, when determining the band combination corresponding to NR, the network device need not refer to the band combination corresponding to MR-DC to facilitate reducing the processing load of the network device.

Optionally, the first band combination set does not include a third band combination, the third band combination is a fallback band combination having the same functionality as the second band combination, and the third band combination and the second band combination correspond to the same radio access technology type.

It should be understood that the first band combination is a fallback band combination that has the same functionality as the second band combination, and that the first band combination and the second band combination correspond to different radio access technology types. . In this case, the first band combination is the fallback band combination obtained by releasing the secondary cell group (SCG) from the second band combination (for example, the LTE band combination is the EN-DC band combination obtained after falling back, or the NR band combination is obtained after the NE-DC band combination is fallen back). The third band combination is a fallback band combination that has the same functionality as the second band combination, and the third band combination and the second band combination correspond to the same radio access technology type. In this case, the third band combination may be a fallback band combination obtained by releasing the secondary cell group (SCG) from the second band combination (e.g., the NR band combination becomes the NR-DC band combination ) or the fallback band combination obtained by releasing at least one secondary cell (SCell) from the second band combination (e.g., the NR band combination is obtained after the NR Carrier aggregation (CA) band combination obtained after fallback) or fallback band combination obtained by releasing the uplink configuration of at least one secondary cell from the second band combination. (eg, NR band combinations obtained after NR CA band combinations are fallen back). Therefore, the large band combination acquired before fallback and the band combination acquired after fallback can support different radio access technology types simply by releasing the SCG. However, by releasing the SCG, the large band combination obtained before fallback and the band combination obtained after fallback may correspond to the same radio access technology type.

Note that in an optional implementation, the NR-DC band combination may alternatively be the NR CA band combination. The fallback band combination obtained by releasing the secondary cell group (SCG) is the same as the fallback band combination obtained by releasing at least one secondary cell (SCell), or the secondary cell group ( SCG) is the same as the fallback band combination obtained by releasing the uplink configuration of at least one secondary cell. In other words, the NR band combination obtained after the NR-DC band combination is fallen back is equivalent to the NR band combination obtained after the NRCA band combination is fallen back. Therefore, the NR band combination is a fallback band combination obtained by releasing the uplink configuration of at least one secondary cell (SCell) or at least one secondary cell from the larger NR band combination, and the NR band combination is It may be considered to include at least one of NR-DC band combinations, NR CA band combinations, and NR single carrier band combinations. In this case, the third band combination is at least one secondary cell (SCell) or a fallback band combination obtained by releasing the uplink configuration of at least one secondary cell from the second band combination. could be.

In an optional implementation, determining the first band combination set based on the second band combination set by the terminal device may include: a. That is, the terminal device obtains the first band combination set by removing the third band combination from the second band combination set. In other words, the terminal device removes the third band combination from the second band combination set and retains the first band combination to obtain the first band combination set. The third band combination may be a fallback band combination obtained by releasing the uplink configuration of at least one secondary cell (SCell) or at least one secondary cell from the second band combination, or a third band combination may not be the fallback band combination obtained by releasing the secondary cell group (SCG) from the second band combination.

For example, in FIG. 3, NR SA BC2 (N_band1) and NR SA BC3 (N_band2) are fallback band combinations that have the same functionality as NR SA BC1 (N_band1, N_band2) and correspond to the same radio access technology type. . That is, NR is the same as NR SA BC1 (N_band1, N_band2)). Therefore, NR SA BC2 (N_band1) and NR SA BC3 (N_band2) are the third band combination, and the first band combination set may not include NR SA BC2 (N_band1) and NR SA BC3 (N_band2) . As another example, NR SA BC6 (N_band4) and NR SA BC7 (N_band5) are fallback band combinations that have the same functionality as NR SA BC5 (N_band4, N_band5) and correspond to the same radio access technology type . . That is, NR is similar to NR SA BC5 (N_band4, N_band5). Therefore, NR SA BC6 (N_band4) and NR SA BC7 (N_band5) are the third band combination, and the first band combination set may not include NR SA BC6 (N_band4) and NR SA BC7 (N_band5) .

In another optional implementation, determining the first set of band combinations based on the second set of band combinations by the terminal device may include the following. That is, the terminal device removes the fourth band combination from the second band combination set and adds the first band combination to the second band combination set to obtain the first band combination set. A fourth band combination is a fallback band combination that has the same function as the second band combination. This implementation requires less modification compared to obtaining and reporting the first set of band combinations with the fourth band combination removed from the second set of band combinations. In particular, in some scenarios the terminal device may remove the fourth band combination from the second set of band combinations to obtain and report the first set of band combinations, or in some other scenarios , the terminal device may use the method for reporting band information described in this embodiment of the present application. This implementation can reduce the complexity of the modification process performed by the terminal device. In other words, the operational difference between the two reporting methods used by the terminal device is whether the first band combination is added.

For example, in FIG. 3, NR SA BC2 (N_band1) and NR SA BC3 (N_band2) are fallback band combinations with the same functionality as NR SA BC1 (N_band1, N_band2), and NR SA BC4 (N_band3) is the NE - Fallback band combinations with the same functionality as DC BC1 (L_band1, N_band3), NR SA BC5 (N_band4, N_band5), NR SA BC6 (N_band4) and NR-SA BC7 (N_band5) are NE-DC BC2 It is a fallback band combination with the same function as (L_band1, L_band2, N_band4, N_band5). Thus, NR SA BC2 (N_band1), NR SA BC3 (N_band2), NR SA BC4 (N_band3), NR SA BC5 (N_band4, N_band5), NR SA BC6 (N_band4), NR SA BC7 (N_band5), etc. 4 band combination. The terminal device may remove these fourth band combinations from the second band combination set and add the first band combinations to the second band combination set. NR SA BC4 (N_band3) and NR SA BC5 (N_band4, N_band5) are the first band combination. Accordingly, the terminal device may add these first band combinations to the second set of band combinations to obtain the first set of band combinations shown in FIG.

The above two implementations of determining the first band combination set may be selected based on the operating scenario of the terminal device. This is not a limitation in this embodiment of the application.

In an optional implementation, the third band combination further includes a fifth band combination and the first band combination does not include the fifth band combination. The third band combination is a fallback band combination that has the same functionality as the second band combination, and the third band combination and the second band combination correspond to the same radio access technology type. For example, as shown in FIG. 12, NR SA BC1 (N_band1, N_band2) in the NR container is the second band combination, NR SA BC2 (N_band1) after NR SA BC1 (N_band1, N_band2) is fallbacked. and NR SA BC3 (N_band2) can be obtained. The two band combination is the third band combination. The fifth band combination is not only a band combination obtained after falling back a large band combination of the same RAT type, but also a band combination obtained after falling back a large band combination of a different RAT type. be. For example, as shown in FIG. 12, the NR containers include NR SA BC1 (N_band1, N_band2), NR SA BC2 (N_band1), NR SA BC3 (N_band2), and NR SA BC4 (N_band3), and the MR-DC container includes NE-DC BC1 (L_band1, N_band1) and NE-DC BC2 (L_band1, N_band3). NR SA BC2 (N_band1) is not only a fallback band combination with the same functionality as NR SA BC1 (N_band1, N_band2) of the same RAT type, but also the same as NE-DC BC1 (L_band1, N_band1) of a different RAT type. It is also a functional fallback band combination. Therefore, NR SA BC2 (N_band1) is the fifth band combination. The fifth band combination is a fallback band combination that has the same functionality as the larger band combination of different RAT types, but according to the description of the previous embodiments, the fifth band combination is explicitly need to be reported. However, since the fifth band combination also belongs to the third band combination and may be obtained after a larger band combination of the same RAT type is fallbacked, the fifth band combination should be explicitly specified to the network device. do not need to report to For example, as shown in FIG. 12, NR SA BC2 (N_band1) is the fifth band combination and can be obtained after NE-DC BC1 (L_band1, N_band1) in the MR-DC container is fallen back; Or it can be obtained after the NR SA BC1 (N_band1, N_band2) in the NR container is fallen back. NE-DC BC1 (L_band1, N_band1) is the large band combination within the MR-DC container and NR SA BC1 (N_band1, N_band2) is the large band combination within the NR container.

In this case, the terminal device may not report NR SA BC2 (N_band1) to the network device. In this embodiment of the present application, if the band combination belongs to both the third band combination and the band combination obtained after the larger band combination of different RAT type is may not report. In other words, the first band combination set reported by the terminal device does not include the fifth band combination. The advantages of this method are: When determining the fallback band combination to be added, the network device only needs to consider the band combination obtained after the larger band combination corresponding to the same RAT type is fallen back and performed by the terminal device. It can be ensured that the overhead required for reporting is reduced.

In an optional implementation, determining the first set of band combinations to be transmitted by the terminal device may specifically include: That is, the terminal device obtains the first band combination set by removing the third band combination from the second band combination set. In other words, the terminal device removes the third band combination from the second band combination set and retains the first band combination to obtain the first band combination set. The third band combination includes the fifth band combination, the first band combination does not include the fifth band combination, and the first band combination set does not include the fifth band combination. The third band combination may be a fallback band combination obtained by releasing the uplink configuration of at least one secondary cell (SCell) or at least one secondary cell from the second band combination, or a third band combination may not be the fallback band combination obtained by releasing the secondary cell group (SCG) from the second band combination.

In another optional implementation, determining the first set of band combinations based on the second set of band combinations by the terminal device may include the following. That is, the terminal device removes the fourth band combination from the second band combination set and adds the first band combination to the second band combination set to obtain the first band combination set. A fourth band combination is a fallback band combination that has the same function as the second band combination. The fourth band combination includes the fifth band combination, the first band combination does not include the fifth band combination, and the first band combination set does not include the fifth band combination.

It can be appreciated that the terminal device may also report the fifth band combination to the network device. In other words, the first band combination reported by the terminal device includes the fifth band combination, and the third band combination does not include the fifth band combination. In other words, the first band combination set reported by the terminal device includes the fifth band combination. For example, as shown in FIG. 12, the terminal device may report NR SA BC2 (N_band1) to the network device. The advantage of this method is that the processing complexity of the terminal device can be reduced.

In an optional implementation, determining the first set of band combinations to be transmitted by the terminal device may specifically include: That is, the terminal device obtains the first band combination set by removing the third band combination from the second band combination set. In other words, the terminal device removes the third band combination from the second band combination set and retains the first band combination to obtain the first band combination set. The third band combination does not include the fifth band combination, the first band combination includes the fifth band combination, and the first band combination set includes the fifth band combination.

In another optional implementation, determining the first set of band combinations based on the second set of band combinations by the terminal device may include the following. That is, the terminal device removes the fourth band combination from the second band combination set and adds the first band combination to the second band combination set to obtain the first band combination set. A fourth band combination is a fallback band combination that has the same function as the second band combination. The fourth band combination includes a fifth band combination, the first band combination includes a fifth band combination, and the first set of band combinations includes a fifth band combination.

This embodiment of the present application does not limit the implementation of determining the first band combination set.

In an optional implementation, the first band combination is a New Radio Standalone (NR SA) band combination if the RAT indicated by the RAT type indication in the terminal device's inquiry message includes NR and MR-DC; The two band combinations include the New Radio Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Dual-Connection (NE-DC) band combination.

In another optional implementation, if the RAT indicated by the RAT type indication in the inquiry message of the terminal device includes EUTRA and MR-DC, the first band combination is the LTE band combination and the second band combination includes the Evolved Universal Mobile Telecommunications System Terrestrial Radio Access New Radio-Duplex Connection (EN-DC) band combination. In other words, although NR and MR-DC are used as examples for the description of FIGS. 3 and 7, the method for reporting band information described in this embodiment of the application applies to EN-DC It is not limited to be used in scenarios where the fallback band combination obtained after the corresponding band combination is fallbacked is the LTE band combination.

In an optional implementation, the radio access technology type corresponding to the first band combination is New Radio (NR) and the radio access technology type corresponding to the second band combination is Evolved Universal Mobile Telecommunications System Terrestrial Radio Access - Including new radio (EUTRA-NR).

In another optional implementation, the radio access technology type corresponding to the first band combination is EUTRA and the radio access technology type corresponding to the second band combination is Evolved Universal Mobile Telecommunications System Terrestrial Radio Access-New Includes radio (EUTRA-NR).

When the terminal device adds BCs to the NR container of the terminal device capability information (or determines the BCs included in the NR container of the first band combination set), the terminal device determines that at least one CC is from the NR SA BC Remove the NR BC obtained after being removed (in other words, the band combination obtained after the NR SA BC is fallen back is still the band combination corresponding to NR), and remove the NR SCG from the NR-DC BC Remove the NR BC obtained after being removed (in other words, the band combination obtained after the NR-DC BC is fallen back is still the band combination corresponding to NR), and the LTE SCG is NE-DC It can be understood that the NR BC obtained after being removed from the BC can be retained.

FIG. 8 is a schematic flow chart of another method for reporting band information, according to an embodiment of the present application. Compared with the method of reporting band information shown in FIG. 6, the method for reporting band information in FIG. 8 further includes the following steps.

301: The terminal device transmits first indication information, the first indication information is used to indicate that the band combination set from the terminal device includes the first band combination.

302: The network device receives first indication information.

Further, steps 303-305 of FIG. 8 are similar to steps 201-203 of FIG. 6 and will not be described again in detail herein.

This implementation allows a network device to explicitly obtain a first band combination without having to reference band combinations corresponding to radio access technology types to determine band combinations corresponding to another radio access technology type. can be understood to be useful for informing network devices of This reduces the implementation complexity of network devices.

Optionally, the first display information indicates that the band combination information reporting rule used by the terminal device indicates that the first band combination set includes the first band combination and the second band combination, but not the third band. Used to indicate that it does not contain combinations. This implementation helps reduce the implementation complexity of network devices and the overhead required to report band combinations supported by terminal devices.

Optionally, the band combination information reporting rule may include at least two of the following. That is, the first band combination set includes the first band combination and the second band combination, but does not include the third band combination. The first band combination set includes a first band combination, a second band combination and a third band combination. The first band combination set includes the first band combination, but does not include the second band combination and the third band combination. In this case, the first display information can be multiple arbitrary values, each arbitrary value corresponding to one band combination information reporting rule. This helps the network device to determine the band combinations supported by the terminal device according to the corresponding rules.

In some embodiments, referring to the embodiment shown in FIG. 6, if the third band combination includes the fifth band combination, the terminal device may not report the fifth band combination, and the terminal device may not report the fifth band combination. The first band combination set reported by does not contain the fifth band combination. Optionally, the terminal device may report a fifth band combination, and the first set of band combinations reported by the terminal device includes the fifth band combination.

FIG. 9 is a schematic flow chart of another method for reporting band information, according to an embodiment of the present application. Compared with the method of reporting band information shown in FIG. 6 or 8, the method of reporting band information shown in FIG. 9 further includes the following steps.

401: The network device sends second indication information, where the second indication information is used to indicate that the band combination set from the terminal device can include the first band combination.

402: The terminal device receives second display information.

Further, steps 403-405 of FIG. 9 are similar to steps 201-203 of FIG. 6 and will not be described again in detail herein.
