The terminal device may also be referred to as a terminal or UE for short, and those skilled in the art will understand its meaning.

The access network device 20 is a device deployed in the access network to provide wireless communication functions for the terminal device 10. The access network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with access network device functions may be different. For example, in the 5G NR system, it is called gNodeB or gNB. With the evolution of communication technology, the name of "access network device" may change. For the convenience of description, in the embodiment of the present application, the above-mentioned device 10 is provided for the terminal device 10. Devices with wireless communication functions are collectively referred to as access network devices. In some embodiments, a communication relationship can be established between the terminal device 10 and the core network network element 30 through the access network device 20.

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

Before introducing the technical solutions of this application, we first introduce and explain the related technologies involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least part of the following contents.

The inter-band (different frequency band) EN-DC supported by the terminal device will report to the network device the CA bandwidth supported by the terminal device in the LTE frequency band and the CA bandwidth supported by the NR frequency band. To increase spectrum utilization efficiency, the spectrum utilization method of intra-band (same frequency band) EN-DC can be used, that is, dual link is performed on LTE band X and NR band nX. In the intra-band CA of the terminal device, BCS (Bandwidth Combination Sets) will be introduced as a terminal device to report its ability to aggregate bandwidth in the frequency band to the base station. Intra-band EN-DC also introduces BCS accordingly. In related technologies, for intra-band EN-DC supported in inter-band EN-DC, supportedBandwidthCombinationSetIntraENDC is used to indicate the BCS supported by each BC (Band Combination). This method works when there's only one intra-band EN-DC band combination in an inter-band EN-DC. However, when there are two or more intra-band EN-DC band combinations, a single IE (Information Element) cannot indicate the different BCSs for different intra-band EN-DC band combinations. For example, in the DC_X-Y_nX-nY combination, where X and Y represent different LTE bands and nX and nY represent the corresponding NR bands, the reporting mechanism in related technologies cannot indicate the BCSs supported by two different intra-band dual links, DC_X_nX and DC_Y_nY.

The terminal device's Capability IE is transmitted within the RRC (Radio Resource Control) IE. When establishing an RRC connection, the terminal device reports a series of capabilities, known as the Capability IE. The network understands the capabilities reported by the terminal device and schedules the terminal device accordingly. During the NR phase, EN-DC remains the dual-link solution of choice for many operators, and the terminal device's combined EN-DC capabilities are also reported in the Capability IE.

The EN-DC band combinations supported by the terminal device are reported to the network using the BandCombinationList IE, a capability IE. A key requirement is that the terminal device must report its supported BCSs to the network so that the network can configure the EN-DC bandwidth based on the device's BCS capabilities and corresponding channel bandwidth.

In related technologies, the reporting content and format of BandCombinationList IE are as follows.

Hereinafter, a frequency band combination is taken as an example, and other frequency band combinations are similar. For example, the terminal device dual link combination is shown in Table 1.

Table 1 Dual-link combination of terminal equipment

For terminal devices that support the DC_3A-41A_n3A-n41A band combination, they report this band combination in the BandCombinationList IE. The terminal device reports the supported bands for LTE and NR in the bandList. In the example shown in Table 1, LTE reports support for bands 3 and 41, while NR reports support for bands n3 and n41. In the BandParameters, etura section reports the BCS supported for LTE bands 3 and 41, while the BandParameters, nr section reports the BCS supported for NR bands n3 and n41. In addition, if the terminal device supports intra-band Eutra/NR dual link, the BCS supported by the terminal device under intra-band EN-DC will be reported through the IE supportedBandwidthCombinationSetIntraENDC. If the IE supportedBandwidthCombinationSetIntraENDC is not reported, BCS0 is used by default. The network side determines the intersection of the three BCS capabilities based on the reported BCS supported by the LTE band, the BCS supported by the NR band, and the BCS supported under intra-band EN-DC, which is the BCS supported by the terminal device. The network side can determine the bandwidth configuration combination supported by the terminal device based on the corresponding BCS and frequency band, and configure the transmission bandwidth for the terminal device.

Regarding the downlink band combination capability of a terminal device, the example band combination DC_3A-41A_n3A-n41A should support the band combination configurations of DC_3A_n3A, DC_3A_n41A, DC_41A_n3A, and DC_41A_n41A. The table shows that its uplink should support the band combination configurations of DC_3A_n3A, DC_3A_n41A, and DC_41A_n3A. By querying the table, you can find the BCS and bandwidth configurations supported by the corresponding intra-band EN-DC, as shown in Table 2 below.

Table 2 EN-DC configurations and bandwidth combination sets defined for intra-band non-contiguous EN-DC

As can be seen, DC_3A_n3A supports BCS0 and BCS1, while DC_41A_n41A only supports BCS0. Therefore, the BCS reporting mechanism supportedBandwidthCombinationSetIntraENDC in the related art only reports one value, and there is no way to fully report the different BCS support status of network-side terminal devices in different frequency bands.

The same problem also arises in the IE intraBandENDC-Support due to the emergence of multiple intra-band EN-DC frequency band combinations. Specifically, for the EN-DC dual link in the example, the terminal device will indicate its support capability for contiguous and non-contiguous bandwidth of intra-band EN-DC through the IE intraBandENDC-Support. For example, the reporting process is as follows:

]]

}

In the related art, the definition of IE intraBandENDC-Support is shown in Table 3.

Table 3 Definition of IE intraBandENDC-Support

Terminal devices can report two different values: non-contiguous or both. If non-contiguous is reported, the terminal device only supports non-contiguous spectrum in the intra-band EN-DC frequency band combination. If both is reported, the terminal device supports both contiguous and non-contiguous spectrum in the intra-band EN-DC frequency band combination. The network can further configure spectrum resources based on the terminal device's supported capabilities.

Because an inter-band EN-DC only reports the contiguous/non-contiguous support capability for one intraBand ENDC-Support, the network has no way of identifying which band the support capability is for when the terminal device supports multiple intra-band EN-DC band combinations. In the example inter-band EN-DC band combination, there is no way to indicate whether the contiguous/non-contiguous support capability is for Band 3/n3 or Band 41/n41.

Please refer to Figure 2, which shows a flow chart of a method for reporting terminal capabilities provided by an embodiment of the present application. The method can be applied to the network architecture shown in Figure 1. The method can include the following step 210.

In step 210, the terminal device sends first information, where the first information is used to indicate capabilities supported by the terminal device for N in-band frequency band combinations, where N is an integer greater than or equal to 2.

Correspondingly, the network device receives first information sent by the terminal device, where the first information is used to indicate capabilities supported by the terminal device for N in-band frequency band combinations, where N is an integer greater than or equal to 2.

In some embodiments, the first information is used to indicate capabilities supported by the terminal device for N intra-band frequency band combinations.

Exemplarily, the first information is used to indicate capabilities commonly supported by the terminal device for N in-band frequency band combinations. Exemplarily, the terminal device sends the first information to the network device. The network device receives the first information sent by the terminal device, thereby being able to learn the capabilities commonly supported by the terminal device for the N in-band frequency band combinations. The network device configures each of the N in-band frequency band combinations based on the capabilities commonly supported by the terminal device for the N in-band frequency band combinations.

Exemplarily, the terminal device sends N pieces of first information to the network device, each piece of first information being used to indicate a capability supported by the terminal device for one of the N in-band frequency band combinations. Exemplarily, the network device receives the N pieces of first information sent by the terminal device and configures each of the N in-band frequency band combinations based on the N pieces of first information.

Exemplarily, the first information includes N sub-information. Each sub-information is used to indicate the capabilities supported by the terminal device for one of the N in-band frequency band combinations. In some embodiments, each sub-information includes one or more bits in the first information. In other embodiments, each sub-information corresponds to a value, and different values correspond to different terminal capabilities. Exemplarily, the terminal device sends the first information including N sub-information to the network device. Exemplarily, the network device receives the first information including N sub-information sent by the terminal device, and configures the corresponding in-band frequency band combination according to the capabilities supported by the terminal device corresponding to each sub-information.

In some embodiments, the intra-band frequency band combination is an intra-band (same frequency band) EN-DC frequency band combination. Exemplarily, different intra-band frequency band combinations correspond to different frequency bands. Exemplarily, an intra-band frequency band combination includes a frequency band supported by LTE reporting and a frequency band supported by NR reporting. Exemplarily, the frequency band supported by LTE reporting and the frequency band supported by NR reporting included in an intra-band frequency band combination belong to the same frequency band. Exemplarily, the frequency band supported by LTE reporting and the frequency band supported by NR reporting included in an intra-band frequency band combination belong to different sub-bands of the same frequency band. Exemplarily, in the frequency band combination of DC_X-Y_nX-nY, X and Y represent different LTE frequency bands, and nX and nY represent corresponding NR frequency bands. Exemplarily, DC_X_nX is an intra-band frequency band combination, and DC_Y_nY is another intra-band frequency band combination.

In some embodiments, the capabilities supported by the terminal device for the intra-band band combination (also referred to as terminal capabilities) include BCS.

Exemplarily, the terminal device supports different BCSs for different in-band frequency band combinations. Exemplarily, the terminal device supports BCS0, BCS1, and BCS2 for the in-band frequency band combination DC_X_nX. Exemplarily, the terminal device supports BCS0 and BCS1 for the in-band frequency band combination DC_Y_nY. BCS0, BCS1, and BCS2 are different BCSs.

Exemplarily, the terminal device sends first information, where the first information is used to indicate the BCSs supported by the terminal device for N in-band frequency band combinations.

In some embodiments, the capabilities supported by the terminal device for an intra-band band combination include contiguous and/or non-contiguous spectrum.

Exemplarily, for different in-band frequency band combinations, the terminal device supports continuous and/or non-contiguous spectrum. Exemplarily, for a band For an intra-band frequency band combination, the terminal device supports contiguous spectrum. Exemplarily, for an intra-band frequency band combination, the terminal device supports non-contiguous spectrum. Exemplarily, for an intra-band frequency band combination, the terminal device supports contiguous spectrum and non-contiguous spectrum. Exemplarily, for an intra-band frequency band combination, the terminal device supports contiguous spectrum or non-contiguous spectrum.

Exemplarily, the terminal device sends first information, where the first information is used to indicate that the terminal device supports contiguous and/or non-contiguous spectrum for N intra-band frequency band combinations.

In some embodiments, the terminal device sends the first information via an uplink channel. Exemplarily, when the capabilities reported by the terminal device for the intra-band frequency band combination are different, the first information corresponds to different information elements (IEs).

Exemplarily, when the capability includes BCS, the first information is a first information element, which is used to indicate the BCSs supported by the terminal device for each of the N intra-band frequency band combinations. Exemplarily, the first information is supportedBandwidthCombinationSetIntraENDC. Of course, the first information may also be an IE other than supportedBandwidthCombinationSetIntraENDC for reporting the BCSs supported by the terminal device for each of the N intra-band frequency band combinations.

Exemplarily, when the capability includes contiguous and/or non-contiguous spectrum, the first information is the second information element, and the first information is used to indicate that the terminal device supports contiguous and/or non-contiguous spectrum for N intra-band frequency band combinations. Exemplarily, the first information is intraBandENDC-Support. Of course, the first information can also be another IE other than intraBandENDC-Support for reporting that the terminal device supports contiguous and/or non-contiguous spectrum for N intra-band frequency band combinations.

Exemplarily, when the terminal device reports the BCSs supported by the terminal device for N in-band frequency band combinations, the terminal device sends a first information element. Exemplarily, when the terminal device reports that the terminal device supports contiguous and/or non-contiguous spectrum for N in-band frequency band combinations, the terminal device sends a second information element. Exemplarily, when the terminal device reports the BCSs supported by the terminal device for N in-band frequency band combinations and the terminal device supports contiguous and/or non-contiguous spectrum for N in-band frequency band combinations, the terminal device sends the first information element and the second information element.

Exemplarily, the first information element and the second information element are different information elements. That is, the BCS supported by the terminal device for N in-band frequency band combinations and the contiguous and/or non-contiguous spectrum supported by the terminal device for N in-band frequency band combinations are reported respectively through two different information elements.

Exemplarily, the first information element and the second information element are the same information element. That is, the BCS supported by the terminal device for N in-band frequency band combinations and the contiguous and/or non-contiguous spectrum supported by the terminal device for N in-band frequency band combinations are reported together through the same information element.

The technical solution provided in the embodiments of the present application involves a terminal device sending first information to a network device to indicate to the network device the capabilities supported by the terminal device for N in-band frequency band combinations. This approach uses the first information to indicate to the network device the capabilities supported by the terminal device for N in-band frequency band combinations, thereby improving the efficiency of reporting terminal capabilities.

Furthermore, the terminal device indicates to the network device the capabilities supported by the terminal device for N in-band frequency band combinations, which is beneficial for the network to configure the N in-band frequency band combinations according to the capabilities supported by the terminal device for the N in-band frequency band combinations, which is beneficial to improving the accuracy of terminal capability reporting and further improving the configuration efficiency on the network side.

In some embodiments, taking the capability including BCS as an example, how the specific first information indicates the capabilities supported by the terminal device for N in-band frequency band combinations is explained in conjunction with the following embodiments. In some embodiments, the manner in which the first information indicates the capabilities supported by the terminal device for N in-band frequency band combinations can be implemented as any one of the following methods 1 to 4.

In mode 1, the BCSs supported by the terminal device for N in-band frequency band combinations are the same, and all include the first BCS.

In some embodiments, the first information is used to indicate a first BCS. Exemplarily, the first BCS includes one or more BCSs. Exemplarily, the terminal device indicates the first BCS by sending the first information to the network device.

Exemplarily, the first information includes M bits, where M is a positive integer not less than S, S is a positive integer, and S is the total number of BCSs. Exemplarily, the first S bits of the M bits correspond to S BCSs. Exemplarily, the values corresponding to the first S bits included in the first information are determined based on the BCS included in the first BCS. Exemplarily, the first bit included in the first information corresponds to BCS0, the second bit corresponds to BCS1, and so on. Exemplarily, when the first BCS includes BCS0 and BCS1, the first and second bits included in the first information are set to 1, and the other bits are set to 0.

Exemplarily, the BCSs supported by the N in-band band combinations are identical, including the first BCS. Exemplarily, each of the N in-band band combinations supports the same BCS. Exemplarily, the nth in-band band combination among the N in-band band combinations supports BCS0, BCS1, and BCS2 (this is merely an example and may be other BCSs), where n is any positive integer not greater than N. In this case, the first BCS is any one or more of BCS0, BCS1, and BCS2.

Exemplarily, the BCSs supported by the N in-band band combinations are not exactly the same, but all include the first BCS. Exemplarily, for each of the N in-band band combinations, the BCSs supported are not exactly the same. Exemplarily, for the i-th in-band band combination among the N in-band band combinations, it supports BCS0, BCS1, and BCS2 (only for example, other BCSs may also be supported), and for the j-th in-band band combination among the N in-band band combinations, it supports BCS0 and BCS1 (only for example, other BCSs may also be supported). i and j are mutually different positive integers not greater than N. In this case, the first BCS is any one or more BCSs among BCS0 and BCS1.

In some embodiments, the first BCS is: a subset of the intersection of BCSs actually supported by the terminal device for N in-band frequency band combinations.

Exemplarily, the terminal device determines an intersection of BCSs actually supported by the N in-band frequency band combinations based on the BCSs actually supported by the terminal device for the N in-band frequency band combinations. Exemplarily, a subset of the intersection is determined as the first BCS. Exemplarily, the subset of the intersection is a non-empty subset.

Exemplarily, the terminal device determines, based on the BCSs actually supported by the terminal device for the N in-band frequency band combinations, that the intersection of the BCSs actually supported by the N in-band frequency band combinations is BCS0 and BCS1. Exemplarily, the subset BCS0 of the intersection is determined as the first BCS. Exemplarily, the subset BCS1 of the intersection is determined as the first BCS. Exemplarily, the subsets BCS0 and BCS1 of the intersection are determined as the first BCS.

In some embodiments, the network side reports the bandList based on the existing terminal capabilities, and the network side learns the frequency bands supported by the terminal device. In some embodiments, the network side supports more than one intra-band EN-DC frequency band combination, and supports intra-band EN-DC on frequency bands a, b, and c (the three frequency band numbers here are only for example, and there can be more intra-band EN-DC frequency band combinations greater than 3). Accordingly, the BCS supported by the terminal device on the intra-band frequency band combinations DC_a_na, DC_b_nb, and DC_c_nc are recorded as BCS _a , BCS _b , and BCS _c respectively. The BCS reported by the terminal side on the supportedBandwidthCombinationSetIntraENDC IE is recorded as BCS _R , and there can be multiple different correspondences between the corresponding BCS _a , BCS _b , and BCS _c and BCS _R. For example, BCS _R is the intersection of BCS _a , BCS _b , and BCS _c . For example, BCS _R is a subset of the intersection of BCS _a , BCS _b , and BCS _c . For example, BCS _R is a non-empty proper subset of the intersection of BCS _a , BCS _b , and BCS _c .

In some embodiments, when defining an inter-band EN-DC band combination and one or more supported intra-band EN-DC band combinations, it is necessary to additionally define at least one BCS _all supported by all intra-band EN-DC band combinations. In this embodiment, this is the intersection of the BCSs supported by the three reported bands a, _b , and _c : BCS _a , BCS b, and BCS c. The BCS _R reported by the terminal device needs to be a subset of BCS _all . For example, the network can configure the bandwidth of the terminal device based on the BCS _R reported by the terminal device.

This embodiment of the present application adopts Method 1 above, without changing the signaling mode. SupportedBandwidthCombinationSetIntraENDC is still used to report the BCS. However, the difference is that the reported BCS is the one supported by all N intra-band frequency band combinations. This method is relatively simple and does not require any changes to the IE. It can also determine the reported BCS for a possible third or even more intra-band EN-DC frequency band combinations using this method.

Mode 2: The first information includes multiple sub-information, each sub-information is used to indicate the BCS supported by the terminal device for one in-band frequency band combination among N in-band frequency band combinations.

In some embodiments, a terminal device transmits first information including multiple sub-information to a network device, each sub-information indicating a BCS supported by the terminal device for one of N in-band frequency band combinations. Correspondingly, the network device receives the first information including multiple sub-information sent by the terminal device and configures the bandwidths of the N in-band frequency band combinations, respectively.

In some embodiments, the plurality of sub-information is independent information, or may be non-independent information included in the first information.

Exemplarily, when the multiple sub-information are non-independent information, the multiple sub-information exists at different positions in the first information and corresponds to different information content. Exemplarily, when the terminal device sends the first information, the information at different positions in the first information is used to indicate the BCS supported by the terminal device for one of the N in-band frequency band combinations. Exemplarily, when the multiple sub-information are independent information, when sending the first information, the terminal device directly sends the multiple sub-information and uses the multiple sub-information to indicate the BCS supported by the terminal device for one of the N in-band frequency band combinations.

In some embodiments, each sub-information corresponds to at least one bit in the first information. Exemplarily, the number of bits corresponding to each sub-information is related to the total number S of BCSs. Exemplarily, each sub-information corresponds to S bits in the first information. In this case, the number of bits corresponding to each sub-information is the same as the total number S of BCSs. That is, there is a one-to-one correspondence between each bit corresponding to the sub-information and the BCS.

In some embodiments, there is no overlap between the bits in the first information corresponding to each sub-information. For example, if the total number of BCSs is 6, then bits 1 to 6 in the first information correspond to one sub-information, bits 7 to 12 correspond to one sub-information, and so on.

In some embodiments, the total number of bits in the first information (i.e., the total length of the first information) is fixed. For example, the total number of bits in the first information is always P, where P is greater than or equal to S (the total number of BCSs) * N (the number of in-band frequency band combinations). In other embodiments, the number of bits in the first information is flexible. For example, the total number of bits in the first information, P, = S * N. When S and N change, the total number of bits, P, in the first information also changes.

In some embodiments, each sub-information is in bitmap format to indicate the BCS supported by the terminal device for an intra-band frequency band combination.

Exemplarily, for a sub-information, the value of the bit corresponding to the sub-information is determined according to the BCS supported by the corresponding in-band frequency band combination. After determining the BCS supported by the in-band frequency band combination, it is only necessary to set the corresponding bit position to 1. Exemplarily, taking the total number of BCS as 6 as an example (BCS0~BCS5), a sub-information corresponds to 6 bits in the first information. Exemplarily, the first bit in the sub-information corresponds to BCS0, the second bit corresponds to BCS1, and so on. Exemplarily, when the BCS supported by the in-band frequency band combination corresponding to the sub-information is BCS0 and BCS3, the value of the 6 bits corresponding to the sub-information is "100100". At this time, "100100" is also called bitmap.

In some embodiments, the plurality of sub-information are arranged according to the numbers of the N in-band frequency band combinations.

In some embodiments, the positions of the plurality of sub-information in the first information are determined based on the descending order of the numbers of the N in-band frequency band combinations. In some embodiments, the positions of the plurality of sub-information in the first information are determined based on the descending order of the numbers of the N in-band frequency band combinations. In some embodiments, the positions of the plurality of sub-information in the first information are determined based on the time sequence of creation of the numbers of the N in-band frequency band combinations.

In some embodiments, the supportedBandwidthCombinationSetIntraENDC field in the related art has 32 bits, each representing a BCS number, with 0 representing non-support and 1 representing support. For example, the bit string for supporting BCS1 would be 0100…0, with a 1 in the second position.

The string supportedBandwidthCombinationSetIntraENDC defined in the related technology is in the following format: supportedBandwidthCombinationSetIntraENDC BIT STRING(SIZE(1..32)).

In some embodiments, taking the total number of BCSs as 6 (BCS0 to BCS5), the highest supported BCS is BCS5, which requires 6 bits to support a single intra-band EN-DC. In some embodiments, the 32-bit bit string is divided into 5 segments, each 6-bit segment indicating the intra-band EN-DC BCS for the corresponding frequency band. For example, one sub-information segment corresponds to a 6-bit segment. As shown below, for each BCS bitmap, a value of 0 indicates dissupport and a value of 1 indicates support. Bit (x-1)*6+1 indicates support for BCS0, bit (x-1)*6+2 indicates support for BCS1, and so on. Bit (x-1)*6+6 indicates support for BCS5, where x is the xth intra-band EN-DC frequency band combination. For example, for five intra-band frequency band combinations, x can be 1, 2, 3, 4, and 5. For example, the correspondence between bitmaps and BCSs is shown in Table 4 below.

Table 4 Correspondence between Bitmap and BCS indication

Bits 1 to 6 represent intra-band EN-DC band a/na, bits 7 to 12 represent intra-band EN-DC band b/nb, bits 13 to 18 represent intra-band EN-DC band c/nc, bits 19 to 24 represent intra-band EN-DC band d/nd, and bits 25 to 30 represent intra-band EN-DC band e/ne. Band a, band b, band c, band d, and band e are the numbers of different frequency bands and can be arranged in ascending order (this is just an example; descending order is also possible). Intra-band EN-DC band a/na, intra-band EN-DC band b/nb, intra-band EN-DC band c/nc, intra-band EN-DC band d/nd, and intra-band EN-DC band e/ne correspond to different intra-band frequency band combinations.

The implementation of method 2 proposed in the embodiment of the present application is relatively simple and does not require modification of the IE structure in the relevant technology. For possible third or even more intra-band EN-DC frequency band combinations, the IE in the relevant technology is fully utilized to meet the number requirements of frequency band combinations.

Mode 3: The number of first information is N, and each first information is used to indicate the BCS supported by the terminal device for one in-band frequency band combination among the N in-band frequency band combinations.

In some embodiments, a terminal device sends N pieces of first information, each piece of first information indicating a BCS supported by the terminal device for one of the N in-band frequency band combinations. Correspondingly, a network device receives the N pieces of first information sent by the terminal device and configures the bandwidths of the N in-band frequency band combinations, respectively.

In some embodiments, when one IE cannot indicate the BCS supported by the terminal device for one of the N intra-band band combinations, a new IE is introduced. For example, this can be solved by introducing a new signaling of supportedBandwidthCombinationSetIntraENDCx. For example, the last x in supportedBandwidthCombinationSetIntraENDCx corresponds to the N intra-band band combinations. For example, supportedBandwidthCombinationSetIntraENDC1 corresponds to the first intra-band band combination, supportedBandwidthCombinationSetIntraENDC2 corresponds to the second intra-band band combination, and so on.

In some embodiments, each piece of first information corresponds to at least one bit. Exemplarily, the number of bits corresponding to each piece of first information is related to the total number S of BCSs. Exemplarily, each piece of first information corresponds to S bits. In this case, the number of bits corresponding to each piece of first information is the same as the total number S of BCSs. That is, there is a one-to-one correspondence between each bit in the first information and the BCS.

In some embodiments, the total number of bits in the first information (i.e., the total length of the first information) is fixed. For example, the total number of bits in the first information is always P, where P is greater than or equal to S (the total number of BCSs). In other embodiments, the number of bits in the first information is flexible. For example, the total number of bits in the first information is P = S, and when S changes, the total number of bits P in the first information also changes.

In some embodiments, each piece of first information is in the form of a bitmap to indicate the BCS supported by the terminal device for an intra-band frequency band combination.

Exemplarily, for a first information, the value of the bit corresponding to the first information is determined according to the BCS supported by the corresponding in-band frequency band combination. After determining the BCS supported by the in-band frequency band combination, it is only necessary to set the corresponding bit position to 1. Exemplarily, taking the total number of BCS as 6 as an example (BCS0~BCS5), the first information corresponds to 6 bits. Exemplarily, the first bit in the first information corresponds to BCS0, the second bit corresponds to BCS1, and so on. Exemplarily, when the BCS supported by the in-band frequency band combination corresponding to the first information is BCS0 and BCS3, the value of the 6 bits corresponding to the first information is "100100". At this time, "100100" is also called bitmap.

In some embodiments, the N first information are arranged according to the numbers of the N in-band frequency band combinations.

In some embodiments, the arrangement positions of the N first information are determined based on the descending order of the numbers of the N in-band frequency band combinations. In some embodiments, the arrangement positions of the N first information are determined based on the descending order of the numbers of the N in-band frequency band combinations. In some embodiments, the arrangement positions of the N first information are determined based on the time sequence of creation of the numbers of the N in-band frequency band combinations.

For example, an ascending order method can be used. For example, if it is necessary to indicate the intra-band EN-DC BCS of frequency bands a, b, and c, they are arranged in ascending order of a < b < c. In the related art, the supportedBandwidthCombinationSetIntraENDC IE can indicate the lowest supported intra-band EN-DC frequency band combination a/na. The newly introduced supportedBandwidthCombinationSetIntraENDC1 is used to indicate the intra-band EN-DC frequency band combination b/nb. The newly introduced supportedBandwidthCombinationSetIntraENDC2 is used to indicate the intra-band EN-DC frequency band combination c/nc, and so on. For example, a definition similar to supportedBandwidthCombinationSetIntraENDC is introduced. The newly defined supportedBandwidthCombinationSetIntraENDCx IE is similar to the supportedBandwidthCombinationSetIntraENDC IE in the related art. It is conditionally mandatory and reported per BC. The judgment criteria are applied separately for each intra-band EN-DC frequency band combination, determining the value of each bit in each introduced IE. For the newly introduced signaling, supportedBandwidthCombinationSetIntraENDCx, a new signaling is required for each additional intra-band EN-DC frequency band combination supported.

Accordingly, you can add it to the BandCombinationList information element in the following way:

BandCombination-vyyyy::=SEQUENCE{

Where vyyyy represents the release (candidate version) being introduced, and yyyy can be a different number.

The same supportedBandwidthCombinationSetIntraENDCx is only used as an example name and can be other names. In some embodiments, the newly introduced IE reports its capabilities in the BandCombinationList IE. The specific reporting method is as follows:

In some embodiments, reference is made to Table 5 below, which is a definition for the supportedBandwidthCombinationSetIntraENDCx IE.

Table 5 supportedBandwidthCombinationSetIntraENDCx IE definition

The embodiments of the present application, through Method 3, specifically address the problem in the related art where a single IE cannot report the capabilities of a terminal device for multiple intra-band frequency band combinations. By introducing a new IE (i.e., multiple first information), the capabilities supported by the terminal device are reported separately for each intra-band frequency band combination. This method is relatively simple to implement, and the corresponding IE can be added to a specific release (candidate version) as needed to report support for intra-band EN-DC BCS.

Mode 4: The first information includes N bit sequences, the N bit sequences correspond one-to-one to N in-band frequency band combinations, each bit sequence includes M bits, the M bits correspond one-to-one to M BCSs, and M is an integer greater than 1.

In some embodiments, the terminal device sends first information including N bit sequences. Correspondingly, the network device receives the first information including N bit sequences sent by the terminal device to configure bandwidths of the N in-band frequency band combinations respectively.

In some embodiments, the jth bit in the ith bit sequence in the N bit sequences is used to indicate that the terminal device is Whether the i-th intra-band band combination in the band combination supports the j-th BCS among M BCSs, where i is a positive integer less than or equal to N, and j is a positive integer less than or equal to M.

In some embodiments, N bit sequences correspond to one of N in-band frequency band combinations. In some embodiments, each bit sequence includes M bits, and the M bits correspond to M BCSs in a one-to-one manner, where M is an integer greater than 1.

In some other embodiments, each bit sequence includes N bits, the first M bits of the N bits correspond one-to-one to M BCSs, and N is an integer greater than or equal to M.

In some embodiments, each bit sequence uses a bitmap format to indicate the BCS supported by the terminal device for an intra-band frequency band combination.

In some embodiments, when the value of the j-th bit in the ith bit sequence in the N bit sequences is a third value, it indicates that the terminal device supports the j-th BCS in the M BCSs for the ith intra-band frequency band combination in the N intra-band frequency band combinations. When the value of the j-th bit in the ith bit sequence in the N bit sequences is a fourth value, it indicates that the terminal device does not support the j-th BCS in the M BCSs for the ith intra-band frequency band combination in the N intra-band frequency band combinations. Exemplarily, the third value is 1 and the fourth value is 0.

Exemplarily, for a bit sequence, the value of each bit in the bit sequence is determined according to the BCS supported by the corresponding in-band frequency band combination. After determining the BCS supported by the in-band frequency band combination, it is only necessary to set the corresponding bit position to 1. Exemplarily, taking the total number of BCS as 6 as an example (BCS0~BCS5), a bit sequence can correspond to 6 bits. Exemplarily, the first bit in a bit sequence corresponds to BCS0, the second bit corresponds to BCS1, and so on. Exemplarily, when the BCS supported by the in-band frequency band combination corresponding to the bit sequence is BCS0 and BCS3, the value of the 6 bits in the bit sequence is "100100". At this time, "100100" is also called bitmap.

In some embodiments, the N bit sequences are arranged according to the numbers of the N in-band frequency band combinations.

In some embodiments, the arrangement positions of the N bit sequences are determined based on the descending order of the numbers of the N in-band frequency band combinations. In some embodiments, the arrangement positions of the N bit sequences are determined based on the ascending order of the numbers of the N in-band frequency band combinations. In some embodiments, the arrangement positions of the N bit sequences are determined based on the time sequence of creation of the numbers of the N in-band frequency band combinations.

In some embodiments, the N bit sequences are designed in a tabular format. In some embodiments, a new signaling "supportedBandwidthCombinationSetIntraENDCtable" is designed, and the signaling reporting format is in a tabular format. Similarly, taking the total number of BCSs as 6 as an example, the IE can be a table with 6 columns and z rows. z is the number of frequency band combinations supported for intra-band EN-DC. Here, still taking z = 3 as an example, the format of "supportedBandwidthCombinationSetIntraENDCtable" is shown in Table 6. Each row in Table 6 represents a bit sequence.

Table 6IE supportedBandwidthCombinationSetIntraENDCtable form

Accordingly, you can add it to the BandCombinationList information element in the following way:

BandCombination-vyyyy::=SEQUENCE{

supportedBandwidthCombinationSetIntraENDCtable BIT STRING(SIZE(1..32))OPTIONAL,

}

Where vyyyy represents the release (candidate version) being introduced, and yyyy can be a different number.

Similarly, supportedBandwidthCombinationSetIntraENDCtable is only used as an example name and can be other names.

The present embodiment, through Method 4, also specifically addresses the problem in the related art where a single IE cannot report the capabilities of a terminal device for multiple in-band frequency band combinations. By introducing new signaling, the capabilities supported by the terminal device for N in-band frequency band combinations are reported in a bit sequence format. This allows reporting the capabilities supported by the terminal device for N in-band frequency band combinations without increasing signaling overhead.

In other embodiments, taking the capability including contiguous and/or non-contiguous spectrum as an example, how the specific first information indicates the capabilities supported by the terminal device for N in-band frequency band combinations is explained in conjunction with the following embodiments. In some embodiments, the manner in which the first information indicates the capabilities supported by the terminal device for N in-band frequency band combinations can be implemented as any one of the following methods 5 to 7.

Mode 5: The number of first information is N, and each first information is used to indicate the terminal device's support capability for continuous and/or non-contiguous spectrum of one intra-band frequency band combination among the N intra-band frequency band combinations.

In some embodiments, a terminal device transmits N pieces of first information, each piece of first information indicating the terminal device's ability to support contiguous and/or non-contiguous spectrum for one of the N in-band frequency band combinations. Correspondingly, a network device receives the N pieces of first information transmitted by the terminal device and configures the bandwidths of the N in-band frequency band combinations, respectively.

In some embodiments, when the first information has a first value, the first information is used to indicate that the terminal device only supports non-contiguous spectrum for an in-band frequency band combination; when the first information has a second value, the first information is used to indicate that the terminal device supports continuous and non-contiguous spectrum for an in-band frequency band combination.

In some embodiments, the first value and the second value are different. For example, the first value is non-contiguous and the second value is both.

In some embodiments, the number of bits of the first information is 1. When the bit is a first value, corresponding to a first value, it is used to indicate that the terminal device supports only non-contiguous spectrum for an intra-band frequency band combination. When the bit is a second value, corresponding to a second value, it is used to indicate that the terminal device supports both contiguous and non-contiguous spectrum for an intra-band frequency band combination.

In other embodiments, the number of bits of the first information is 2. The first bit indicates whether the value is the first value, and the second bit indicates whether the value is the second value. For example, when the first bit is the first value, it indicates that the first information has the first value. When the second bit is the first value, it indicates that the first information has the second value. In some embodiments, the first value is 1 and the second value is 0.

In some embodiments, the N first information are arranged according to the numbers of the N in-band frequency band combinations.

In some embodiments, the arrangement positions of the N first information are determined based on the descending order of the numbers of the N in-band frequency band combinations. In some embodiments, the arrangement positions of the N first information are determined based on the descending order of the numbers of the N in-band frequency band combinations. In some embodiments, the arrangement positions of the N first information are determined based on the time sequence of creation of the numbers of the N in-band frequency band combinations.

In some embodiments, to address the issue in related art where intraBandENDC-Support cannot clearly indicate support for contiguous/non-contiguous spectrum for different intra-band EN-DCs under an inter-band ENDC, a new intraBandENDC-Supportx is introduced to indicate whether a new intra-band EN-DC frequency band combination supports non-contiguous bandwidth combinations, or both. For example, the last x in intraBandENDC-Supportx can be numbered starting from 1, if additional signaling is required to indicate support for contiguous/non-contiguous spectrum for a second intra-band EN-DC. For a larger number of intra-band EN-DC frequency band combinations, new IEs can be introduced as needed. Similarly, an ascending method can be adopted. For example, if it is necessary to indicate the support of continuous/non-continuous spectrum of intra-band EN-DC of frequency bands a, b, and c, they are arranged in ascending order of a<b<c. The intraBandENDC-Support IE in the related technology can indicate the lowest supported intra-band EN-DC frequency band combination a/na, and the new intraBandENDC-Support1 is introduced to indicate the intra-band EN-DC frequency band combination b/nb, and the new intraBandENDC-Support2 is introduced to indicate the intra-band EN-DC frequency band combination c/nc, and so on.

Introduce a new IE in the IE of MRDC-Parameters information element as follows:

The embodiments of the present application specifically address the problem in the related art that a single IE cannot report the terminal device's capabilities for multiple intra-band frequency band combinations through Method 5. By introducing a new IE (i.e., multiple first information), the capabilities supported by the terminal device are reported separately for each intra-band frequency band combination. This method is relatively simple to implement, and corresponding IEs can be added as needed to report the support capabilities for intra-band EN-DC continuous and/or non-contiguous spectrum.

Method 6, the first information includes N values, the N values correspond one-to-one to N in-band frequency band combinations, and each value is used to indicate the terminal device's support capability for continuous and/or non-continuous spectrum for one of the N in-band frequency band combinations.

In some embodiments, a terminal device transmits N values, each corresponding to one of N in-band frequency band combinations, and each value indicates the terminal device's ability to support contiguous and/or non-contiguous spectrum for one of the N in-band frequency band combinations. Correspondingly, a network device receives the N values transmitted by the terminal device and configures the bandwidths of the N in-band frequency band combinations.

In some embodiments, the value includes a first value and a second value. When the value is the first value, it indicates that the terminal device only supports non-contiguous spectrum for the in-band frequency band combination corresponding to the value; when the value is the second value, it indicates that the terminal device supports both contiguous and non-contiguous spectrum for the in-band frequency band combination corresponding to the value. In some embodiments, the first value and the second value are different. For example, the first value is non-contiguous and the second value is both.

In some embodiments, the N values are arranged according to the numbers of the N in-band frequency band combinations.

In some embodiments, the arrangement positions of the N values are determined based on the order of the numbers of the N in-band frequency band combinations from large to small. In some embodiments, the arrangement positions of the N values are determined based on the order of the numbers of the N in-band frequency band combinations from small to large. In the example, the arrangement positions of the N values are determined according to the creation time sequence of the numbers of the N in-band frequency band combinations.

In some embodiments, one value corresponds to one bit, and the first information includes N bits. When one of the bits is a first value, it corresponds to the first value and is used to indicate that the terminal device supports only non-contiguous spectrum for an intra-band frequency band combination. When the bit is a second value, it corresponds to the second value and is used to indicate that the terminal device supports both contiguous and non-contiguous spectrum for an intra-band frequency band combination.

In other embodiments, one value corresponds to two bits, and the first information includes 2N bits. The first bit of the two bits corresponding to one value indicates whether it is the first value, and the second bit of the two bits corresponding to one value is used to indicate whether it is the second value. For example, when the first bit is the first value, it indicates that the value is the first value. When the second bit is the first value, it indicates that the value is the second value. In some embodiments, the first value is 1 and the second value is 0.

In other embodiments, when the first information includes 2N bits, the first information may also be considered as N bit sequences. Exemplarily, the N bit sequences correspond one-to-one to the N values, and each bit sequence includes two bits.

In some embodiments, the intraBand ENDC-Support in the related art is still used, and no new signaling is introduced. Exemplarily, intraBand ENDC-Support can also be a table with z rows and 1 column, as shown in Table 7. Here, taking z as 3 as an example, the first row represents the continuous/non-contiguous support capability of the first intra-band EN-DC frequency band combination, the second row represents the continuous/non-contiguous support capability of the second intra-band EN-DC frequency band combination, and the third row represents the continuous/non-contiguous support capability of the third intra-band EN-DC frequency band combination. At this time, the table with z rows and 1 column corresponds to the above N values. The value of each row can be one of non-contiguous and both.

Table 7 IntraBandENDC-Support when the number of intraband band combinations is 3

The corresponding continuous and/or non-contiguous spectrum support capabilities are formally defined as shown in Table 8 below.

Table 8 Definition of support capability for contiguous and/or non-contiguous spectrum

Method 6 of the embodiment of the present application is relatively simple to implement. According to the needs, the corresponding IE can be added in a specific release (candidate version) to realize the reporting of the support capability for continuous/non-continuous spectrum of the intra-band EN-DC BCS band combination.

Mode 7: The terminal device has the same capability to support continuous and/or non-contiguous spectrum for N intra-band frequency band combinations.

In some embodiments, when the first information has a first value, the first information is used to indicate that the terminal device supports only non-contiguous spectrum for each of the N intra-band frequency band combinations. In other embodiments, when the first information has a second value, the first information is used to indicate that the terminal device supports both contiguous and non-contiguous spectrum for each of the N intra-band frequency band combinations.

In some embodiments, a terminal device transmits first information, where the first information is a first value or a second value. The first value indicates that the terminal device supports only non-contiguous spectrum for each of N in-band frequency band combinations, and the second value indicates that the terminal device supports both contiguous and non-contiguous spectrum for each of the N in-band frequency band combinations. Correspondingly, the network device receives the first information transmitted by the terminal device and configures each of the N in-band frequency band combinations.

In some embodiments, the first value and the second value are different. For example, the first value is non-contiguous and the second value is both.

In some embodiments, the first information corresponds to 1 bit. When the bit is a first value, it corresponds to a first value, which is used to indicate that the terminal device only supports non-contiguous spectrum for an intra-band frequency band combination. When the bit is a second value, it corresponds to a second value, which is used to indicate that the terminal device only supports non-contiguous spectrum for an intra-band frequency band combination. The end device supports both contiguous and non-contiguous spectrum for one intra-band frequency band combination.

In other embodiments, the first information corresponds to two bits, the first bit of the two bits indicates whether it is the first value, and the second bit of the two bits is used to indicate whether it is the second value. For example, when the first bit is the first value, it indicates that the value is the first value. When the second bit is the first value, it indicates that the value is the second value. In some embodiments, the first value is 1 and the second value is 0.
