The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 can be distributed in a cell managed by each access network device 20. The terminal device can also be referred to as a terminal or a UE, and those skilled in the art can understand its meaning.

[0036] The access network device 20 is a device deployed in an access network to provide wireless communication functions for the terminal device 10. The access network device 20 can 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 can be different, for example, in a 5G NR system, it is called gNodeB or gNB. With the evolution of communication technology, the name of "access network device" can change. For the convenience of description, in the embodiments of the present application, the above-mentioned devices providing wireless communication functions for the terminal device 10 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 element 30 through the access network device 20. Exemplarily, in an LTE system, the access network device 20 can be an EUTRAN (Evolved Universal Terrestrial Radio Access Network) or one or more eNodeBs in the EUTRAN; in a 5G NR system, the access network device 20 can be a RAN (Radio Access Network) or one or more gNBs in the RAN. In the embodiments of the present application, the "network device" mentioned refers to the access network device 20, such as a base station, unless otherwise specified.

[0037] The core network element 30 is a network element deployed in the core network, and the function of the core network element 30 is mainly to provide user connection, management of users, and completion of bearer for services, and to provide an interface to an external network as a bearer network. For example, the core network element in the 5G NR system can include an AMF (Access and Mobility Management Function) entity, a UPF (User Plane Function) entity, and an SMF (Session Management Function) entity, and the like.

[0038] In some embodiments, the access network device 20 and the core network element 30 communicate with each other through an air interface technology, such as an NG interface in the 5G NR system. The access network device 20 and the terminal device 10 communicate with each other through an air interface technology, such as a Uu interface.

[0039] The "5G NR system" in the embodiments of the present application can also be referred to as a 5G system or an NR system, but those skilled in the art can understand its meaning. The technical solutions described in the embodiments of the present application can be applicable to the LTE system, and can also be applicable to the 5G NR system, and can also be applicable to the subsequent evolution system of the 5G NR system (for example, the B5G (Beyound 5G) system, the 6G system (6th Generation System, the sixth generation mobile communication system)), and can also be applicable to other communication systems such as the NB-IoT (Narrow Band Internet of Things, Narrow Band Internet of Things) system, and the like, and the present application does not limit this.

[0040] In the embodiments of the present application, the network device can serve a cell, and the terminal device communicates with the network device through transmission resources (for example, frequency domain resources, or frequency spectrum resources) on a carrier used by the cell. The cell can be a cell corresponding to the 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 (Small cell). The small cell can include a metro cell, a micro cell, a pico cell, a femto cell, and the like, and these small cells have the characteristics of small coverage and low transmit power, and are suitable for providing high-speed data transmission services.

[0041] Before introducing the technical solutions of the present application, the related technologies involved in the present application are introduced and explained. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way, and all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0042] The inter-band EN-DC supported by the terminal device reports the CA bandwidth supported by the terminal device in the LTE frequency band and the CA bandwidth supported by the terminal device in the NR frequency band to the network device. In order to increase the utilization efficiency of the spectrum, the spectrum usage mode of intra-band EN-DC can be used, that is, dual connectivity is performed on the LTE band X and the NR band nX. On the intra-band CA of the terminal device, BCS (Bandwidth Combination Sets) is introduced as the capability of the terminal device reporting to the base station the aggregation bandwidth of the terminal device in the frequency band. The intra-band EN-DC also introduces BCS accordingly. In the related technology, for the intra-band EN-DC supported in the inter-band EN-DC, supportedBandwidthCombinationSetIntraENDC is used to indicate the BCS supported by each BC (Band Combination). This method is applicable only in the case of one intra-band EN-DC frequency band combination in the inter-band EN-DC, but in the case of two or even multiple intra-band EN-DC frequency band combinations, a single IE (Information Element) cannot indicate the different BCS of different intra-band EN-DC frequency band combinations. For example, in the combination of DC_X-Y_nX-nY, X and Y represent different LTE frequency bands, nX and nY represent the corresponding NR frequency bands, and the reporting mechanism in the related technology cannot explain the BCS supported by the two different intra-band dual links of DC_X_nX and DC_Y_nY.

[0043] The capability IE of the terminal device is transmitted in the RRC (Radio Resource Control) IE, and when the RRC connection is established, the terminal device reports a series of capabilities, that is, the capability IE. The network side understands the capabilities reported by the terminal device, and schedules the terminal device according to different capabilities. In the NR related stage, EN-DC is still the dual connectivity scheme selected by many operators, and the combination capability of the terminal device corresponding to EN-DC is also reported in the capability IE.

[0044] Among them, the EN-DC frequency band combination supported by the terminal device belongs to the capability IE of the BandCombinationList (frequency band combination list) IE, and the terminal device reports the frequency band combination supported by the terminal device to the network side through the IE. The key point is that the terminal device needs to report the network side to the terminal device. The network side can configure the bandwidth of the EN-DC of the terminal device according to the corresponding BCS capability supported by the terminal device and the corresponding channel bandwidth.

[0045] In the related art, the reporting content and format of the BandCombinationList IE are as follows.

[0075] Take one frequency band combination as an example below, and other frequency band combinations are similar to this. Exemplarily, the terminal device dual-link combination is shown in Table 1.

[0076] Table 1: Terminal device dual-link combination

[0077] For the terminal device supporting the frequency band combination of DC_3A-41A_n3A-n41A, the terminal device reports the frequency band combination on the BandCombinationList IE. The reporting manner is that the terminal device reports the frequency bands supported by LTE and NR respectively in the bandList. In the example of Table 1, the terminal device reports that the supported frequency bands of LTE are band 3 and band 41, and the supported frequency bands of NR are band n3 and band n41. In the BandParameters, the eutra part reports the BCS supported in the LTE frequency bands band 3 and band 41, and in the BandParameters, the nr part reports the BCS supported in the NR frequency bands band n3 and band n41. In addition, if the terminal device supports intra-band Eutra / NR dual-link, it will report the BCS supported by the terminal device under intra-band EN-DC through the IE supportedBandwidthCombinationSetIntraENDC, and if the IE supportedBandwidthCombinationSetIntraENDC is not reported, the default is to use BCS0. The network side determines the intersection of the three BCS capabilities according to the reported BCS supported by the LTE frequency band, the BCS supported by the NR frequency 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 according to the corresponding BCS and frequency band, and configure the transmission bandwidth of the terminal device.

[0078] For the downlink band combination capability of the 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, while 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, the corresponding BCS and bandwidth configurations supported by intra-band EN-DC can be found, as shown in the following table 2.

[0079] Table 2 EN-DC configurations and bandwidth combination sets defined for intra-band non-contiguous EN-DC

[0080] It can be seen that DC_3A_n3A supports BCS0 and BCS1, while DC_41A_n41A supports BCS0. Therefore, the BCS reporting mechanism supportedBandwidthCombinationSetIntraENDC in the related art only reports one value, and there is no way to completely report the different BCS support conditions of the terminal device on the network side under different frequency bands.

[0081] The same problem also occurs in the IE intraBandENDC-Support due to the emergence of multiple intra-band EN-DC band combinations. Specifically, for the EN-DC dual link in the example, the terminal device will indicate the support capability of the continuous and non-continuous bandwidth of the intra-band EN-DC through the IE intraBandENDC-Support. Exemplarily, the reporting process is as follows:

[0095] ]]

[0096] }

[0097] In the related art, the definition of IE intraBandENDC-Support is shown in Table 3.

[0098] Table 3 Definition of IE intraBandENDC-Support

[0099] The terminal device can report two different values of non-contiguous or Both. If non-contiguous is reported, the terminal device only supports non-contiguous spectrum on the intra-band EN-DC frequency band combination. If both is reported, the terminal device supports contiguous and non-contiguous spectrum on the intra-band EN-DC frequency band combination. The network side can further configure the spectrum resource according to the capability supported by the terminal device.

[0100] Since an inter-band EN-DC only reports one intraBandENDC-Support contiguous / non-contiguous support capability, in the case of supporting multiple intra-band EN-DC frequency band combinations by the terminal device, the network side has no way to distinguish the specific support capability for which frequency band. In the example inter-band EN-DC frequency band combination, it is not possible to indicate the contiguous / non-contiguous support capability on the frequency band 3 / n3 or the frequency band 41 / n41.

[0101] Referring to FIG. 2, a flowchart of a method for reporting terminal capability provided by an embodiment of the present application is shown. The method can be applied to the network architecture shown in FIG. 1. The method can include the following step 210.

[0102] In step 210, the terminal device sends first information, which is used to indicate the capability supported by the terminal device for N intra-band frequency band combinations, N being an integer greater than or equal to 2.

[0103] Correspondingly, the network device receives the first information sent by the terminal device, which is used to indicate the capability supported by the terminal device for N intra-band frequency band combinations, N being an integer greater than or equal to 2.

[0104] In some embodiments, the first information is used to indicate the capability supported by the terminal device for N intra-band frequency band combinations.

[0105] For example, the first information is used to indicate the capability commonly supported by the terminal device for N intra-band frequency band combinations. For example, the terminal device sends the first information to the network device. The network device receives the first information sent by the terminal device, and thus can know the capability commonly supported by the terminal device for N intra-band frequency band combinations. The network device configures N intra-band frequency band combinations respectively based on the capability commonly supported by the terminal device for N intra-band frequency band combinations.

[0106] Exemplarily, the terminal device sends N first information to the network device, each of the first information being used to indicate a capability supported by the terminal device for one of the N intra-band frequency range combinations. Exemplarily, the network device receives the N first information sent by the terminal device, and configures the N intra-band frequency range combinations respectively according to the N first information.

[0107] Exemplarily, the first information includes N sub-information. Each of the sub-information is used to indicate a capability supported by the terminal device for one of the N intra-band frequency range combinations. In some embodiments, each of the sub-information includes one or more bits in the first information. In other embodiments, each of the sub-information corresponds to a value, and different values correspond to different terminal capabilities. Exemplarily, the terminal device sends the first information including the N sub-information to the network device. Exemplarily, the network device receives the first information including the N sub-information sent by the terminal device, and configures the corresponding intra-band frequency range combination according to the capability supported by the terminal device corresponding to each of the sub-information.

[0108] In some embodiments, the intra-band frequency range combination is an intra-band EN-DC frequency range combination. Exemplarily, different intra-band frequency range combinations correspond to different frequency ranges. Exemplarily, one of the intra-band frequency range combinations includes one LTE reported supported frequency range and one NR reported supported frequency range. Exemplarily, the LTE reported supported frequency range and the NR reported supported frequency range included in one of the intra-band frequency range combinations belong to the same frequency range. Exemplarily, the LTE reported supported frequency range and the NR reported supported frequency range included in one of the intra-band frequency range combinations belong to different sub-bands of the same frequency range. Exemplarily, under the frequency range combination of DC_X-Y_nX-nY, X and Y represent different LTE frequency ranges, and nX and nY represent corresponding NR frequency ranges. Exemplarily, DC_X_nX is one of the intra-band frequency range combinations, and DC_Y_nY is another of the intra-band frequency range combinations.

[0109] In some embodiments, the capability supported by the terminal device for the intra-band frequency range combination (also referred to as terminal capability) includes BCS.

[0110] Exemplarily, the terminal device supports different BCS for different intra-band frequency range combinations. Exemplarily, the terminal device supports BCS0, BCS1, and BCS2 for the intra-band frequency range combination DC_X_nX. Exemplarily, the terminal device supports BCS0 and BCS1 for the intra-band frequency range combination DC_Y_nY. BCS0, BCS1, and BCS2 are different BCSs.

[0111] Exemplarily, the terminal device sends first information, and the first information is used to indicate the BCSs supported by the terminal device for the N intra-band frequency range combinations respectively.

[0112] In some embodiments, the supported capability of the terminal device for the intra-band combination of frequency bands comprises contiguous and / or non-contiguous spectrum.

[0113] Exemplarily, the terminal device supports contiguous and / or non-contiguous spectrum for different intra-band combination of frequency bands. Exemplarily, the terminal device supports contiguous spectrum for one intra-band combination of frequency bands. Exemplarily, the terminal device supports non-contiguous spectrum for one intra-band combination of frequency bands. Exemplarily, the terminal device supports contiguous spectrum and non-contiguous spectrum for one intra-band combination of frequency bands. Exemplarily, the terminal device supports contiguous spectrum or non-contiguous spectrum for one intra-band combination of frequency bands.

[0114] Exemplarily, the terminal device sends the first information, and the first information is used to indicate that the terminal device supports contiguous and / or non-contiguous spectrum for N intra-band combination of frequency bands respectively.

[0115] In some embodiments, the terminal device sends the first information through an uplink channel. Exemplarily, when the reported capability of the terminal device for the intra-band combination of frequency bands is different, the first information corresponds to different information elements (IE).

[0116] Exemplarily, when the capability comprises BCS, the first information is a first information element, and the first information is used to indicate the BCS supported by the terminal device for N intra-band combination of frequency bands respectively. Exemplarily, the first information is supportedBandwidthCombinationSetIntraENDC. Of course, the first information can also be other IE for reporting the BCS supported by the terminal device for N intra-band combination of frequency bands respectively, except for supportedBandwidthCombinationSetIntraENDC.

[0117] Exemplarily, when the capability comprises contiguous and / or non-contiguous spectrum, the first information is a second information element, and the first information is used to indicate the contiguous and / or non-contiguous spectrum supported by the terminal device for N intra-band combination of frequency bands respectively. Exemplarily, the first information is intraBandENDC-Support. Of course, the first information can also be other IE for reporting the contiguous and / or non-contiguous spectrum supported by the terminal device for N intra-band combination of frequency bands respectively, except for intraBandENDC-Support.

[0118] Exemplarily, the terminal device sends the first information element when reporting the BCSs supported by the terminal device for the N in-band frequency range combinations respectively. Exemplarily, the terminal device sends the second information element when reporting that the terminal device supports continuous and / or discontinuous spectrum for the N in-band frequency range combinations respectively. Exemplarily, the terminal device sends the first information element and the second information element when reporting the BCSs supported by the terminal device for the N in-band frequency range combinations respectively and reporting that the terminal device supports continuous and / or discontinuous spectrum for the N in-band frequency range combinations respectively.

[0119] Exemplarily, the first information element and the second information element are different information elements. That is, the BCSs supported by the terminal device for the N in-band frequency range combinations respectively and the continuous and / or discontinuous spectrum supported by the terminal device for the N in-band frequency range combinations respectively are reported by two different information elements respectively.

[0120] Exemplarily, the first information element and the second information element are the same information element. That is, the BCSs supported by the terminal device for the N in-band frequency range combinations respectively and the continuous and / or discontinuous spectrum supported by the terminal device for the N in-band frequency range combinations respectively are reported together by the same information element.

[0121] The technical scheme provided by the embodiments of the present application is that the terminal device sends the first information to the network device to indicate the capability supported by the terminal device for the N in-band frequency range combinations respectively. The above-mentioned manner realizes the indication of the capability supported by the terminal device for the N in-band frequency range combinations respectively to the network device through the first information, which is beneficial to improving the reporting efficiency of the terminal capability.

[0122] Further, the terminal device indicates the capability supported by the terminal device for the N in-band frequency range combinations respectively to the network device, which is beneficial to the network to configure the N in-band frequency range combinations respectively according to the capability supported by the terminal device for the N in-band frequency range combinations respectively, and is beneficial to improving the accuracy of the terminal capability reporting and further improving the configuration efficiency of the network side.

[0123] In some embodiments, taking the capability including the BCS as an example, how the specific first information indicates the capability supported by the terminal device for the N in-band frequency range combinations respectively is explained and described in combination with the following embodiments. In some embodiments, the manner in which the first information indicates the capability supported by the terminal device for the N in-band frequency range combinations respectively can be implemented as any one of the following manners 1-4.

[0124] Manner 1: the BCSs supported by the terminal device for the N in-band frequency range combinations respectively are the same and all include the first BCS.

[0125] In some embodiments, the first information is used to indicate the first BCS. Illustratively, the first BCS includes one or more BCSs. Illustratively, the terminal device indicates the first BCS by sending the first information to the network device.

[0126] Illustratively, the first information includes M bits, M is a positive integer not less than S, S is a positive integer, and S is the total number of BCSs. Illustratively, the first S bits of the M bits correspond to the S BCSs. Illustratively, the first S bits of the first information correspond to values respectively determined according to the BCSs included in the first BCS. Illustratively, the first bit of the first information corresponds to BCS0, the second bit corresponds to BCS1, and so on. Illustratively, when the first BCS includes BCS0 and BCS1, the first bit and the second bit of the first information are set to 1, and the other bits are set to 0.

[0127] Illustratively, the N in-band frequency range combinations respectively support the same BCSs, and all include the first BCS. Illustratively, each of the N in-band frequency range combinations supports the same BCSs. Illustratively, the nth in-band frequency range combination of the N in-band frequency range combinations supports BCS0, BCS1, and BCS2 (only as an example, other BCSs are also possible), where n is any positive integer not greater than N. At this time, the first BCS is any one or more of BCS0, BCS1, and BCS2.

[0128] Illustratively, the N in-band frequency range combinations respectively support different BCSs, but all include the first BCS. Illustratively, each of the N in-band frequency range combinations supports different BCSs. Illustratively, the ith in-band frequency range combination of the N in-band frequency range combinations supports BCS0, BCS1, and BCS2 (only as an example, other BCSs are also possible), and the jth in-band frequency range combination of the N in-band frequency range combinations supports BCS0 and BCS1 (only as an example, other BCSs are also possible), where i and j are different positive integers not greater than N. At this time, the first BCS is any one or more of BCS0 and BCS1.

[0129] In some embodiments, the first BCS is a subset of the intersection of the BCSs actually supported by the terminal device for the N in-band frequency range combinations.

[0130] Illustratively, the terminal device determines the intersection of the BCSs actually supported by the terminal device for the N in-band frequency range combinations according to the BCSs actually supported by the terminal device for the N in-band frequency range combinations. Illustratively, the subset of the intersection is determined as the first BCS. Illustratively, the subset of the intersection is a non-empty subset.

[0131] Exemplarily, the terminal device determines the intersection of the BCSs actually supported by the N intra-band frequency combination respectively as BCS0, BCS1 according to the BCSs actually supported by the terminal device for the N intra-band frequency combination respectively. 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.

[0132] In some embodiments, the network side reports the bandList according to the existing terminal capability, and the network side knows the frequency bands supported by the terminal device. In some embodiments, the network side supports more than one intra-band EN-DC frequency combination, and supports intra-band EN-DC on frequency bands a, b, c (here, the three frequency band numbers are only examples, and there can be more than three intra-band EN-DC frequency combinations). Correspondingly, the BCSs respectively supported by the terminal device on the intra-band frequency combination DC_a_na, DC_b_nb, DC_c_nc are recorded as BCS a , BCS b , and BCS c . The BCSs reported by the terminal side on the supportedBandwidthCombinationSetIntraENDC IE are recorded as BCS R , BCS a , and BCS b , and BCS c . There can be various different corresponding relationships between BCS R . For example, BCS R is the intersection of BCS a , BCS b , and BCS c . For example, BCS R is the subset of the intersection of BCS a , BCS b , and BCS c . For example, BCS R is the non-empty proper subset of the intersection of BCS a , BCS b , and BCS c .

[0133] In some embodiments, when an inter-band EN-DC frequency combination and one or more intra-band EN-DC frequency combinations supported by the inter-band EN-DC frequency combination are defined, at least one BCS allIn this embodiment, the BCS is BCS a , BCS b , BCS c The intersection of the three reported frequency bands a, b, and c supported BCS. And the BCS R reported by the terminal device needs to be a subset of the BCS all . Exemplarily, the network side can configure the bandwidth of the terminal device according to the BCS R reported by the terminal device.

[0134] The embodiment of the present application adopts the above-mentioned manner 1, does not change the mode of signaling, still uses supportedBandwidthCombinationSetIntraENDC to report BCS, but the difference is that the reported BCS is the BCS supported by the N intra-band EN-DC frequency band combinations. This way is relatively simple, does not need to make any changes to the IE, and for the possible third or even more intra-band EN-DC frequency band combinations, the reported BCS can be determined through the above-mentioned manner.

[0135] Manner 2, the first information includes a plurality of sub-information, and each sub-information is used to indicate the BCS supported by the terminal device for one of the N intra-band frequency band combinations.

[0136] In some embodiments, the terminal device sends the first information including a plurality of sub-information to the network device, and each sub-information is used to indicate the BCS supported by the terminal device for one of the N intra-band frequency band combinations. Correspondingly, the network device receives the first information including a plurality of sub-information sent by the terminal device, to respectively configure the bandwidth of the N intra-band frequency band combinations.

[0137] In some embodiments, the plurality of sub-information is independent information, or non-independent information included in the first information.

[0138] Exemplarily, when the plurality of sub-information is non-independent information, the plurality of sub-information exists in different positions in the first information, corresponding to different information content. Exemplarily, when the terminal device sends the first information, the terminal device uses the information in different positions in the first information to indicate the BCS supported by the terminal device for one of the N intra-band frequency band combinations. Exemplarily, when the plurality of sub-information is independent information, the terminal device directly sends the plurality of sub-information when sending the first information, and uses the plurality of sub-information to indicate the BCS supported by the terminal device for one of the N intra-band frequency band combinations.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] In some embodiments, the plurality of sub-information are arranged according to the numbers of the N in-band frequency band combinations.

[0145] In some embodiments, the arrangement positions of the plurality of sub-information in the first information are determined according to the descending order of the numbers of the N intra-band frequency range combinations. In some embodiments, the arrangement positions of the plurality of sub-information in the first information are determined according to the ascending order of the numbers of the N intra-band frequency range combinations. In some embodiments, the arrangement positions of the plurality of sub-information in the first information are determined according to the time order of the numbers of the N intra-band frequency range combinations.

[0146] In some embodiments, the supportedBandwidthCombinationSetIntraENDC in the related art has 32 bits, each bit of which represents the number of a BCS, 0 represents not supported, and 1 represents supported. For example, for a bit string supporting BCS1, the value should be 0100…0, that is, 1 in the second position.

[0147] The string supportedBandwidthCombinationSetIntraENDC defined in the related art has the following form: supportedBandwidthCombinationSetIntraENDC BIT STRING(SIZE(1..32)).

[0148] In some embodiments, taking the total number of BCS as 6 (BCS0-BCS5 exist) as an example, the highest support of BCS is BCS5, that is, 6 bits are needed to complete the support of intra-band EN-DC. In some embodiments, the 32-bit bit string is divided into 5 segments, each segment of which has 6 bits indicating the intra-band EN-DC BCS of the corresponding frequency range. Exemplarily, one sub-information corresponds to one segment of 6 bits. As shown below, each BCS bitmap, the value of 0 represents not supported, and the value of 1 represents supported. The (x-1)*6+1 bit indicates whether BCS0 is supported, the (x-1)*6+2 bit indicates whether BCS1 is supported, …, the (x-1)*6+6 bit indicates whether BCS5 is supported, where x is the xth intra-band EN-DC frequency range combination, and x takes the value of 1, 2, 3, 4, and 5 for example. Exemplarily, the correspondence between the bitmap and the BCS is shown in Table 4 as follows.

[0149] Table 4 Correspondence between bitmap and BCS indication

[0150] The first to sixth bitmaps represent intra-band EN-DC band a / na, the seventh to twelfth bitmaps represent intra-band EN-DC band b / nb, the thirteenth to eighteenth bitmaps represent intra-band EN-DC band c / nc, the nineteenth to twenty-fourth bitmaps represent intra-band EN-DC band d / nd, and the twenty-fifth to thirtieth bitmaps represent intra-band EN-DC band e / ne. The bands a, b, c, d, and e are numbers of different frequency bands and can be arranged in ascending order (here, only an example, and can also be arranged in descending order). The intra-band EN-DC band a / na, the intra-band EN-DC band b / nb, the intra-band EN-DC band c / nc, the intra-band EN-DC band d / nd, and the intra-band EN-DC band e / ne correspond to different intra-band frequency band combinations.

[0151] The implementation of the manner 2 is relatively simple, does not need to modify the IE structure in the related art, and sufficiently utilizes the IE in the related art for the possible third or more intra-band EN-DC frequency band combinations, so as to meet the number requirement of the frequency band combinations.

[0152] The manner 3 is that the number of the first information is N, and each first information is used to indicate a BCS supported by the terminal device for one of the N intra-band frequency band combinations.

[0153] In some embodiments, the terminal device sends N first information, and each first information is used to indicate a BCS supported by the terminal device for one of the N intra-band frequency band combinations. Correspondingly, the network device receives the N first information sent by the terminal device, and configures the bandwidths of the N intra-band frequency band combinations respectively.

[0154] In some embodiments, a new IE is introduced in case one IE cannot indicate the BCS supported by the terminal device for one of the N intra-band frequency range combinations. Exemplarily, this can be solved by introducing a new supportedBandwidthCombinationSetIntraENDCx signaling. Exemplarily, the number of the last x in supportedBandwidthCombinationSetIntraENDCx corresponds to the N intra-band frequency range combinations. Exemplarily, supportedBandwidthCombinationSetIntraENDC1 corresponds to the first intra-band frequency range combination, supportedBandwidthCombinationSetIntraENDC2 corresponds to the second intra-band frequency range combination, and so on.

[0155] In some embodiments, each first information corresponds to at least one bit. Exemplarily, the number of bits corresponding to each first information is related to the total number S of BCSs. Exemplarily, each first information corresponds to S bits. At this time, the number of bits corresponding to each first information is the same as the total number S of BCSs. That is, each bit in the first information and the BCSs are one-to-one correspondence.

[0156] 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, and 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 P in the first information is equal to S, and when S changes, the total number of bits P in the first information also changes.

[0157] In some embodiments, each first information indicates the BCS supported by the terminal device for one intra-band frequency range combination in the form of bitmap.

[0158] Exemplarily, for one first information, the value of the bit corresponding to the first information is determined according to the BCS supported by the intra-band frequency range combination corresponding to the first information. When the BCS supported by the intra-band frequency range combination is determined, the corresponding bit is set to 1. Exemplarily, taking the total number of BCSs as 6 (BCS0-BCS5) as an example, 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 intra-band frequency range 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.

[0159] In some embodiments, the N first information is arranged according to the number of the N intra-band frequency range combinations.

[0160] In some embodiments, the arrangement position of the N first information is determined according to the descending order of the number of the N intra-band frequency range combinations. In some embodiments, the arrangement position of the N first information is determined according to the ascending order of the number of the N intra-band frequency range combinations. In some embodiments, the arrangement position of the N first information is determined according to the time sequence of the number of the N intra-band frequency range combinations.

[0161] Exemplarily, an ascending order method can be adopted, for example, if the frequency ranges a, b and c need to be indicated, the ascending order a < b < c is arranged, the supportedBandwidthCombinationSetIntraENDC IE in the related art can indicate the lowest supported intra-band EN-DC frequency range combination a / na, the supportedBandwidthCombinationSetIntraENDC1 is newly introduced to indicate the intra-band EN-DC frequency range combination b / nb, the supportedBandwidthCombinationSetIntraENDC2 is newly introduced to indicate the intra-band EN-DC frequency range combination c / nc, and so on. Exemplarily, a definition similar to the supportedBandwidthCombinationSetIntraENDC is introduced. The newly defined supportedBandwidthCombinationSetIntraENDCx is an IE of the same type as the IE supportedBandwidthCombinationSetIntraENDC in the related art, which is reported per BC, is conditionally mandatory, and the judgment condition is judged separately on each intra-band EN-DC frequency range combination to determine the value of each bit in each introduced IE, which is consistent with the judgment condition of the IE in the related art. For the newly introduced signaling supportedBandwidthCombinationSetIntraENDCx, if one more intra-band EN-DC intra-band frequency range combination is supported, a new signaling needs to be introduced.

[0162] Correspondingly, the BandCombinationList information element can be added in the following manner:

[0163] BandCombination-vyyyy ::= SEQUENCE {

[0164] supportedBandwidthCombinationSetIntraENDCx BIT STRING (SIZE (1..32)) OPTIONAL,

[0165] }

[0166] where vyyyy represents the release (candidate version) in which it is introduced, here yyyy can be different numbers.

[0167] The same supportedBandwidthCombinationSetIntraENDCx is only an example of the name, it can be other names. In some embodiments, the newly introduced IE reports its capability in the BandCombinationList IE, and the specific reporting method is as follows:

[0199] In some embodiments, reference is made to Table 5 below, which is a definition of the supportedBandwidthCombinationSetIntraENDCx IE.

[0200] Table 5 Definition of the supportedBandwidthCombinationSetIntraENDCx IE

[0201] Embodiments of the present application solve the problem that one IE cannot report the terminal device's capability for multiple intra-band EN-DC BCSs by way 3. By introducing a new IE (i.e., multiple first information), the terminal device's supported capability is reported for each intra-band EN-DC BCS. This way is relatively simple, and the corresponding IE can be added in a specific release to achieve the reporting of the intra-band EN-DC BCS support according to the needs.

[0202] Way 4: the first information includes N bit sequences, the N bit sequences and the N intra-band EN-DC BCSs correspond to each other, each bit sequence includes M bits, the M bits and the M BCSs correspond to each other, and M is an integer greater than 1.

[0203] In some embodiments, the terminal device sends the first information including N bit sequences. Correspondingly, the network device receives the first information including N bit sequences sent by the terminal device, and configures the bandwidths of the N intra-band EN-DC BCSs respectively.

[0204] In some embodiments, the jth bit in the ith bit sequence in the N bit sequences is used to indicate whether the terminal device supports the jth BCS in the M BCSs for the ith intra-band frequency segment combination in the N intra-band frequency segment combinations, i is a positive integer less than or equal to N, and j is a positive integer less than or equal to M.

[0205] In some embodiments, the N bit sequences correspond to the N intra-band frequency segment combinations one by one. In some embodiments, each bit sequence includes M bits, the M bits correspond to the M BCSs one by one, and M is an integer greater than 1.

[0206] In some other embodiments, each bit sequence includes N bits, the first M bits in the N bits correspond to the M BCSs one by one, and N is an integer greater than or equal to M.

[0207] In some embodiments, each bit sequence indicates the BCSs supported by the terminal device for an intra-band frequency segment combination in the form of bitmap.

[0208] In some embodiments, when the jth bit in the ith bit sequence in the N bit sequences is the third value, it indicates that the terminal device supports the jth BCS in the M BCSs for the ith intra-band frequency segment combination in the N intra-band frequency segment combinations. When the jth bit in the ith bit sequence in the N bit sequences is the fourth value, it indicates that the terminal device does not support the jth BCS in the M BCSs for the ith intra-band frequency segment combination in the N intra-band frequency segment combinations. Exemplarily, the third value is 1, and the fourth value is 0.

[0209] Exemplarily, for a bit sequence, the values of the bits in the bit sequence are determined according to the BCSs supported by the intra-band frequency segment combination corresponding to the bit sequence. After determining the BCSs supported by the intra-band frequency segment combination, the corresponding bit is set to 1. Exemplarily, taking the total number of BCSs as 6 (BCS0-BCS5) as an example, 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 BCSs supported by the intra-band frequency segment combination corresponding to the bit sequence are BCS0 and BCS3, the values of the 6 bits in the bit sequence are “100100”, and at this time, “100100” is also called bitmap.

[0210] In some embodiments, the N bit sequences are arranged according to the numbers of the N intra-band frequency segment combinations.

[0211] In some embodiments, the arrangement position of the N bit sequences is determined according to the descending order of the number of the N intra-band frequency range combinations. In some embodiments, the arrangement position of the N bit sequences is determined according to the ascending order of the number of the N intra-band frequency range combinations. In some embodiments, the arrangement position of the N bit sequences is determined according to the time order of the creation of the number of the N intra-band frequency range combinations.

[0212] In some embodiments, the N bit sequences are designed in the form of a table. In some embodiments, a new signaling supportedBandwidthCombinationSetIntraENDCtable is designed, and the signaling reported in the form of a table. Similarly, taking the total number of BCS as 6 as an example, the IE can be a table of 6 columns and z rows. Z is the number of supported intra-band EN-DC frequency range combinations. Here, still taking z = 3 as an example, the form of supportedBandwidthCombinationSetIntraENDCtable is shown in Table 6. Each row in Table 6 represents a bit sequence.

[0213] Table 6 IE supportedBandwidthCombinationSetIntraENDCtable form

[0214] Correspondingly, the BandCombinationList information element can be added in the following manner,

[0215] BandCombination-vyyyy ::= SEQUENCE {

[0216] supportedBandwidthCombinationSetIntraENDCtable BIT STRING (SIZE (1..32)) OPTIONAL,

[0217] }

[0218] Wherein vyyyy represents the introduced release (candidate version), and here yyyy can be different numbers.

[0219] Similarly, supportedBandwidthCombinationSetIntraENDCtable is only an example of the name, which can be other names.

[0220] The embodiment of the present application solves the problem that one IE cannot report the capability of the terminal device for multiple in-band frequency combination in the related art by way 4. By introducing new signaling, the capability of the terminal device for N in-band frequency combinations is reported in the form of a bit sequence, and the capability of the terminal device for N in-band frequency combinations can be reported without additional signaling overhead.

[0221] In other embodiments, the first information indicates the capability of the terminal device for N in-band frequency combinations in the case that the capability includes continuous and / or discontinuous spectrum, which is explained in combination with the following embodiments. In some embodiments, the manner in which the first information indicates the capability of the terminal device for N in-band frequency combinations can be implemented as any one of the following ways 5-7.

[0222] Way 5, the number of the first information is N, and each first information is used to indicate the support capability of the terminal device for continuous and / or discontinuous spectrum of one in-band frequency combination of the N in-band frequency combinations.

[0223] In some embodiments, the terminal device sends N first information, and each first information is used to indicate the support capability of the terminal device for continuous and / or discontinuous spectrum of one in-band frequency combination of the N in-band frequency combinations. Correspondingly, the network device receives the N first information sent by the terminal device to configure the bandwidth of the N in-band frequency combinations respectively.

[0224] In some embodiments, in the case that the first information is a first value, the first information is used to indicate that the terminal device only supports discontinuous spectrum for one in-band frequency combination; in the case that the first information is a second value, the first information is used to indicate that the terminal device supports continuous and discontinuous spectrum for one in-band frequency combination.

[0225] In some embodiments, the first value and the second value are different, and exemplarily, the first value is non-contiguous, and the second value is both.

[0226] In some embodiments, the number of the bit of the first information is 1. When the bit is a first value, corresponding to the first value, it is used to indicate that the terminal device only supports discontinuous spectrum for one in-band frequency combination. When the bit is a second value, corresponding to the second value, it is used to indicate that the terminal device supports continuous and discontinuous spectrum for one in-band frequency combination.

[0227] In some embodiments, the number of bits of the first information is 2. Among them, the first bit indicates whether it is the first value, and the second bit is used to indicate whether it is the second value. Illustratively, when the first bit is the first value, it indicates that the first information is the first value. When the second bit is the first value, it indicates that the first information is the second value. In some embodiments, the first value is 1, and the second value is 0.

[0228] In some embodiments, the N first information is arranged according to the number of the N intra-band frequency band combination.

[0229] In some embodiments, the arrangement position of the N first information is determined according to the descending order of the number of the N intra-band frequency band combination. In some embodiments, the arrangement position of the N first information is determined according to the ascending order of the number of the N intra-band frequency band combination. In some embodiments, the arrangement position of the N first information is determined according to the time sequence of the creation of the number of the N intra-band frequency band combination.

[0230] In some embodiments, for the problem that the intraBandENDC-Support in the related art cannot clearly indicate the support of the continuous / non-continuous spectrum of different intra-band EN-DC under inter-band EN-DC, a new intraBandENDC-Supportx is introduced to indicate whether the new intra-band EN-DC frequency band combination supports the non-continuous bandwidth combination, or both. Illustratively, the number of the last x in the intraBandENDC-Supportx can start from 1, and if additional signaling is needed, it is introduced to indicate the support of the continuous / non-continuous spectrum of the second intra-band EN-DC. For a larger number of intra-band EN-DC frequency band combinations, new IEs can be introduced according to the needs. Similarly, an ascending method can be used, such as indicating the support of the continuous / non-continuous spectrum of the intra-band EN-DC of the frequency bands a, b, and c, and arranging them in ascending order of a<b<c. The intraBandENDC-Support IE in the related art can indicate the lowest supported intra-band EN-DC frequency band combination a / na, the newly introduced intraBandENDC-Support1 can indicate the intra-band EN-DC frequency band combination b / nb, the newly introduced intraBandENDC-Support2 can indicate the intra-band EN-DC frequency band combination c / nc, and so on.

[0248] The embodiment of the present application solves the problem that one IE cannot report the terminal device capability for multiple intra-band frequency combination in the related art by way 5. By introducing a new IE (i.e., multiple first information), the terminal device supported capability is reported for each intra-band frequency combination. This way is relatively simple, and the corresponding IE can be added according to the requirement to realize the reporting of the support capability of intra-band EN-DC continuous and / or non-continuous spectrum.

[0249] In way 6, the first information includes N values, the N values and the N intra-band frequency combinations are one-to-one corresponding, and each value is used to indicate the support capability of continuous and / or non-continuous spectrum of the terminal device for one intra-band frequency combination in the N intra-band frequency combinations.

[0250] In some embodiments, the terminal device sends N values, the N values and the N intra-band frequency combinations are one-to-one corresponding, and each value is used to indicate the support capability of continuous and / or non-continuous spectrum of the terminal device for one intra-band frequency combination in the N intra-band frequency combinations. Correspondingly, the network device receives the N values sent by the terminal device to respectively configure the bandwidth of the N intra-band frequency combinations.

[0251] In some embodiments, the value includes a first value and a second value. In the case of the value being the first value, it indicates that the terminal device only supports non-continuous spectrum for the intra-band frequency combination corresponding to the value; in the case of the value being the second value, it indicates that the terminal device supports continuous and non-continuous spectrum for the intra-band frequency 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.

[0252] In some embodiments, the N values are arranged according to the number of the N intra-band frequency combinations.

[0253] In some embodiments, the arrangement position of the N values is determined according to the order from large to small of the number of the N intra-band frequency combinations. In some embodiments, the arrangement position of the N values is determined according to the order from small to large of the number of the N intra-band frequency combinations. In some embodiments, the arrangement position of the N values is determined according to the creation time order of the number of the N intra-band frequency combinations.

[0254] 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 a first value, indicating that the terminal device supports only non-contiguous spectrum for one intra-band EN-DC frequency band combination. When the bit is a second value, it corresponds to a second value, indicating that the terminal device supports contiguous and non-contiguous spectrum for one intra-band EN-DC frequency band combination.

[0255] In other embodiments, one value corresponds to two bits, and the first information includes 2N bits. One value corresponds to a first bit of the two bits, indicating whether it is the first value, and one value corresponds to a second bit of the two bits, indicating whether it is the second value. For example, when the first bit is a 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.

[0256] In other embodiments, when the first information includes 2N bits, the first information can also be considered as an N-bit sequence. For example, the N-bit sequence and the N values correspond to each other one by one, and each bit sequence includes two bits.

[0257] In some embodiments, the intraBandENDC-Support in the related art is still used, and no new signaling is introduced. For example, the intraBandENDC-Support can also be a z-row 1-column table, as shown in Table 7, where z is 3. The first row represents the contiguous / non-contiguous support capability of the first intra-band EN-DC frequency band combination, the second row represents the contiguous / non-contiguous support capability of the second intra-band EN-DC frequency band combination, and the third row represents the contiguous / non-contiguous support capability of the third intra-band EN-DC frequency band combination. At this time, the z-row 1-column table corresponds to the N values described above. The value of each row can be one of non-contiguous and both.

[0259] The form of the corresponding contiguous and / or non-contiguous spectrum support capability is defined as shown in Table 8.

[0260] Table 8 definition of contiguous and / or non-contiguous spectrum support capability

[0261] In a manner 6 of the embodiments of the present application, the implementation is relatively simple, and the corresponding IE can be added in a specific release (candidate version) according to the requirement to implement the reporting of the support capability of the continuous / discontinuous spectrum of the intra-band EN-DC BCS frequency band combination.

[0262] In a manner 7, the support capability of the terminal device for the continuous and / or discontinuous spectrum of the N intra-band frequency band combinations is the same.

[0263] In some embodiments, when the first information is of a first value, the first information is used to indicate that the terminal device only supports the discontinuous spectrum for the N intra-band frequency band combinations. In other embodiments, when the first information is of a second value, the first information is used to indicate that the terminal device supports the continuous and discontinuous spectrum for the N intra-band frequency band combinations.

[0264] In some embodiments, the terminal device sends the first information, which is of the first value or the second value, the first value is used to indicate that the terminal device only supports the discontinuous spectrum for the N intra-band frequency band combinations, and the second value is used to indicate that the terminal device supports the continuous and discontinuous spectrum for the N intra-band frequency band combinations. Correspondingly, the network device receives the first information sent by the terminal device to configure the N intra-band frequency band combinations respectively.

[0265] In some embodiments, the first value and the second value are different, and exemplarily, the first value is non-contiguous, and the second value is both.

[0266] In some embodiments, the first information corresponds to 1 bit, when the bit is of a first numerical value, the first value is used to indicate that the terminal device only supports the discontinuous spectrum for one intra-band frequency band combination. When the bit is of a second numerical value, the second value is used to indicate that the terminal device supports the continuous and discontinuous spectrum for one intra-band frequency band combination.

[0267] In other embodiments, the first information corresponds to 2 bits, a first bit of the 2 bits indicates whether the first value, and a second bit of the 2 bits is used to indicate whether the second value. Exemplarily, when the first bit is of a first numerical value, the value is the first value. When the second bit is of a first numerical value, the value is the second value. In some embodiments, the first numerical value is 1, and the second numerical value is 0.

[0268] For the problem that the intraBandENDC-Support in the related art cannot clearly indicate the continuous / discontinuous spectrum support of different intra-band EN-DC under inter-band ENDC, only a single intraBandENDC-Support IE can be reported, and the reported capability and the capability of the terminal intra-band EN-DC frequency band combination can also be further subdivided according to Table 9 as follows.
