[0028] The embodiments of the present disclosure provide an information processing method, a terminal, a network device, a communication system, and a storage medium.

[0029] In a first aspect, an embodiment of the present disclosure proposes an information processing method, which is executed by a terminal, and includes: sending first information, wherein the first information is used to indicate information related to multiple in-band dual connections supported by the terminal in the dual connection.

[0030] In the above embodiment, the terminal can report information related to multiple in-band dual connections supported by the terminal during dual connection, so that the network device can identify the multiple in-band dual connections supported by the terminal, thereby reducing the occurrence of incorrect bandwidth configuration for the frequency band supported by the terminal due to the inability to identify multiple in-band dual connections, which is beneficial for the network device to configure the bandwidth for the frequency band supported by the terminal.

[0031] In combination with some embodiments of the first aspect, in some embodiments, the first information includes at least one of the following: first signaling, wherein the first signaling is used to indicate the number of in-band dual connections supported by the terminal; second signaling, wherein the second signaling is used to indicate the BCS of at least one in-band dual connection among multiple in-band dual connections supported by the terminal.

[0032] In the above embodiment, the terminal may report the first signaling so that the network knows the number of intra-band dual connections supported by the terminal; and / or the terminal may report the second signaling so that the network device knows the situation of multiple intra-band BCSs supported by the terminal. When the second signaling indicates the terminal at least two intra-band dual connection BCSs, it is beneficial for the network device to accurately identify the BCSs of each intra-band dual connection, thereby reducing the possibility of the network device incorrectly configuring bandwidth for the frequency band supported by the terminal.

[0033] In combination with some embodiments of the first aspect, in some embodiments, the second signaling includes at least one of a first sub-signaling and a second sub-signaling; wherein the first sub-signaling is used to indicate the BCS of the first in-band dual connection among multiple in-band dual connections supported by the terminal, and the second sub-signaling is used to indicate the BCS of the second in-band dual connection among multiple in-band dual connections supported by the terminal; the second in-band dual connection is other in-band dual connections among the multiple in-band dual connections supported by the terminal except the first in-band dual connection.

[0034] In the above embodiment, the terminal can report the first sub-signaling and the second sub-signaling so that the network device is aware of the BCS of the first in-band dual connection and the second in-band dual connection among the multiple in-band dual connections supported by the terminal, thereby facilitating the network device to accurately identify the BCS of the first in-band dual connection and the second in-band dual connection, thereby reducing the occurrence of the network device incorrectly configuring bandwidth for the frequency band supported by the terminal. Furthermore, if the first sub-signaling can be an existing signaling and the second sub-signaling can be a newly introduced signaling, the present disclosure can also minimize the overhead of the introduced signaling, thereby allowing the terminal to report the BCS of at least two in-band dual connections with relatively small signaling overhead; and the existing first sub-signaling can be used.

[0035] In combination with some embodiments of the first aspect, in some embodiments, the first information includes first signaling and second signaling, and the second signaling includes first sub-signaling and second sub-signaling; wherein, the first signaling is used to indicate that the number of in-band dual connections supported by the terminal is two; the first sub-signaling is used to indicate the BCS of the first in-band dual connection among the multiple in-band dual connections supported by the terminal; and the second sub-signaling is used to indicate the BCS of the second in-band dual connection among the multiple in-band dual connections supported by the terminal.

[0036] In the above embodiment, the terminal can report the first signaling so that the network device knows that the number of in-band dual connections supported by the terminal is two; and can report the first sub-signaling and the second sub-signaling so that the network device accurately knows the BCS of the two in-band dual connections supported by the terminal, which can help the network device accurately configure the bandwidth for the frequency band supported by the terminal.

[0038] In the above embodiment, the terminal can report the first signaling so that the network device knows that the number of in-band dual connections supported by the terminal is three or more; and can report the first sub-signaling so that the network device knows the BCS of one of the in-band dual connections (i.e., the first in-band dual connection), and report the second sub-signaling so that the network device knows the BCS of the other two or more in-band dual connections (i.e., the second in-band dual connection), thereby facilitating the network device to accurately configure the bandwidth for the frequency band supported by the terminal.

[0039] Furthermore, when there are two or more second intra-band dual connections, the BCSs of the two or more second intra-band dual connections can be indicated by the same second sub-signaling, thereby saving signaling overhead and completing unified indication of the BCSs of multiple second intra-band dual connections; alternatively, the BCSs of the two or more second intra-band dual connections can be separately indicated by different fields of the same second sub-signaling, thereby saving signaling overhead and completing separate indication of multiple second intra-band dual connections; alternatively, the BCSs of the two or more second intra-band dual connections can be separately indicated by different second sub-signals, thereby achieving accurate indication of each second intra-band dual connection.

[0100] The following embodiments of the present disclosure may be applied to the information processing system 100 shown in FIG1 , or a portion thereof, but are not limited thereto.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0102] In some embodiments, in Evolved-UMTS Terrestrial Radio Access (EUTRA)-New Radio (NR) dual connectivity, a bandwidth combination set supported by a terminal in the dual connectivity consists of two parts: one is an E-UTRA bandwidth combination set identical to the E-UTRA CA configuration, and the other is an NR bandwidth combination set identical to the NR CA configuration. Optionally, in DC_1A-3A_n5A-n40A, the bandwidth combination set supported by the terminal consists of the bandwidth combination set of EUTRA CA_1A-3A and the bandwidth combination set of NR CA_n5A-n40A. Optionally, if the dual connectivity includes intra-band dual connectivity, such as DC_1A-3A_n3A-n41A including DC_3A_n3A dual connectivity, the bandwidth combination set supported by the terminal consists of the bandwidth combination set of EUTRA CA_1A-3A, the bandwidth combination set of NR CA_n3A-n41A, and the bandwidth combination set of intra-band dual connectivity DC_3A_n3A. Optionally, the bandwidth supported by each frequency band is the intersection of the bandwidth combination sets that include that frequency band; for example, the bandwidth supported by frequency band 3 is the intersection of the bandwidth combination set CA_1A-3A and the bandwidth combination set DC_3A_n3A. Optionally, dual connectivity refers to dual connectivity, and intra-band dual connectivity refers to intra-band dual connectivity.

[0103] As shown in Table 1, the bandwidth combination set of CA_1A-3A supported by the terminal may be BCS0.

[0104] Table 1

[0105] As shown in Table 2, the bandwidth combination set of DC_3A_n3A supported by the terminal may be BCS0.

[0106] Table 2

[0107] Then the bandwidth set supported by band 3 is: {5MHz, 10MHz, 15MHz, 20MHz}.

[0108] In some embodiments, the bandwidth combination set of the E-UTRA CA configuration part in EUTRA-NR dual connectivity can be reported by signaling supportedBandwidthCombinationSetEUTRA; the bandwidth combination set of the NR CA configuration part can be reported by signaling supportedBandwidthCombinationSet; the bandwidth combination set of intra-band dual connectivity can be reported by signaling supportedBandwidthCombinationSetIntraENDC.

[0109] Therefore, when EUTRA-NR dual connectivity includes two or more intra-band dual connectivity, such as DC_3A-41A_n3A-n41A, since the terminal can only report one supportedBandwidthCombinationSetIntraENDC signaling, the terminal reports the bandwidth combination set of DC_3A_n3A or the bandwidth combination set of DC_41A_n41A. The terminal cannot indicate or report both at the same time, and the network cannot recognize it. This may cause configuration errors.

[0110] For example, for DC_3A-41A_n3A-n41A, as shown in Table 3, the bandwidth combination set of CA_3A-41A supported by the terminal may be BCS0.

[0111] Table 3

[0112] As described in Table 4, the bandwidth combination set of CA n3A-n41A supported by the terminal may be BCS0.

[0113] Table 4

[0114] As shown in Table 5, the bandwidth combination set of DC_3A_n3A and DC_41A_n41A supported by the terminal may be BCS0.

[0115] Table 5

[0116] Based on the above principles, Band 3 supports the following bandwidths: 5 MHz, 10 MHz, 15 MHz, and 20 MHz; Band 41 supports a bandwidth of 20 MHz; Band n3 supports the following bandwidths: 5 MHz, 10 MHz, 15 MHz, 20 MHz, 25 MHz, and 30 MHz; and Band n41 supports the following bandwidths: 40 MHz, 60 MHz, 80 MHz, and 100 MHz. Because the terminal can only report a BCS for one intra-band dual connectivity using the supportedBandwidthCombinationSetIntraENDC signaling, the network may consider BCS0 to be a band combination set supported by DC_3A_n3A. At this time, the network will assume that the bandwidths supported by band 3 are: 5MHz, 10MHz, 15MHz and 20MHz; the bandwidths supported by band 41 are: 5MHz, 10MHz, 15MHz and 20MHz; the bandwidths supported by band n3 are: 5MHz, 10MHz, 15MHz, 20MHz, 25MHz and 30MHz; the bandwidths supported by band n41 are: 10MHz, 15MHz, 20MHz, 40MHz, 50MHz, 60MHz, 80MHz, 90MHz and 100MHz. As a result, the bandwidth configuration on bands 41 and n41 may be incorrect.

[0167] In some embodiments, when the first information includes the first sub-signaling, the third signaling and the fourth signaling, and the first information does not include the second sub-signaling, the network device configures the bandwidth for at least one frequency band supported by the terminal based on the first sub-signaling, the third signaling and the fourth signaling.

[0168] In an optional embodiment, the network device determines that the terminal supports an in-band dual connectivity when the first information includes the first sub-signaling and does not include the second sub-signaling. Here, the first information may include the first sub-signaling, the third sub-signaling, and the fourth sub-signaling, and the first information does not include the second sub-signaling.

[0169] For example, if the dual connectivity supported by the terminal includes one in-band dual connectivity, for example, DC_1A-3A_n3A-n41A includes the in-band dual connectivity of DC_3A_n3A, the network device obtains first information, which includes a first sub-signaling, a third signaling, and a fourth signaling, but does not include the first signaling. For example, the first sub-signaling indicates that the BCS of DC_3A_n3A is {5 MHz, 10 MHz, 15 MHz, and 20 MHz}. The network device can then configure at least one bandwidth of 5 MHz, 10 MHz, 15 MHz, and 20 MHz for frequency band 3 supported by the terminal. At this point, because the first information does not include the second sub-signaling, the network device can also determine that the terminal supports only one in-band dual connectivity.

[0170] In some embodiments, when the first information includes the first sub-signaling, the third signaling and the fourth signaling, and the first information does not include the first signaling, the network device configures the bandwidth for at least one frequency band supported by the terminal based on the first sub-signaling, the third signaling and the fourth signaling.

[0171] In some optional embodiments, the network device determines that the terminal supports an in-band dual connectivity when the first information includes the first sub-signaling and does not include the first signaling. Here, the first information may include the first sub-signaling, the third signaling, and the fourth signaling, and the first information does not include the first signaling.

[0172] In some embodiments, when the first information includes the first sub-signaling, the second sub-signaling, the third signaling and the fourth signaling, the network device configures the bandwidth for at least one frequency band supported by the terminal based on the first sub-signaling, the second sub-signaling, the third signaling and the fourth signaling.

[0173] For example, if the dual connectivity supported by the terminal includes an in-band dual connectivity of DC_3A-41A_n3A-n41A, the network device obtains first information including a first sub-signaling, a second sub-signaling, a third signaling, and a fourth signaling. For example, the first sub-signaling indicates that the BCS of DC_3A_n3A is {5MHz, 10MHz, 15MHz, 20MHz}, and the second sub-signaling indicates that DC_41A_n41A is 20MHz. The network device can then configure at least one bandwidth of 5MHz, 10MHz, 15MHz, and 20MHz for frequency band 3 supported by the terminal, and a bandwidth of 20MHz for frequency band 4 supported by the terminal. In this case, if the first information further includes the first signaling, the number of in-band dual connectivity supported by the terminal can be determined based on the first sub-signaling. Alternatively, if the first information does not include the first signaling, the number of in-band dual connectivity supported by the terminal can be determined to be two.

[0174] Exemplarily, if the dual connectivity supported by the terminal includes in-band dual connectivity of DC_3A-4A-5A_n3A-n4A-n5A. The network device obtains first information, and the first information includes a first sub-signaling, a second sub-signaling, a third signaling and a fourth signaling; for example, the first sub-signaling is used to indicate that the BCS of DC_3A_n3A is {5MHz, 10MHz, 15MHz, 20MHz}; the two second sub-signals are used to indicate that the BCS of DC_5A_n5A is {5MHz, 10MHz, 15MHz, 20MHz} and the BCS of DC_5A_n5A is {15MHz, 20MHz}, respectively, or, the two fields of the second sub-signaling are used to indicate that the BCS of DC_5A_n5A is {5MHz, 10MHz, 15MHz, 20MHz} and the BCS of DC_5A_n5A is {15MHz, 20MHz}, respectively; then the network device can configure at least one bandwidth of 5MHz, 10MHz, 15MHz and 20MHz for both frequency bands 3 and 4 supported by the terminal, and configure at least one bandwidth of 15MHz and 20MHz for frequency band 5 supported by the terminal.

[0175] In some embodiments, when the first information includes the first signaling, the first sub-signaling, the third signaling and the fourth signaling, the network device configures the bandwidth for at least one frequency band supported by the terminal based on the first sub-signaling, the third signaling and the fourth signaling.

[0176] In some optional embodiments, when the first information includes the first signaling and the first sub-signaling, it is determined that the BCSs of the multiple intra-band dual connections supported by the terminal are all the BCSs indicated by the first sub-signaling. Here, the first information includes the first signaling and the first sub-signaling, but the first information does not include the second sub-signaling.

[0177] Exemplarily, the network device receives the first information. If the first signaling in the first information indicates that there is one in-band dual connection, and the first sub-signaling is used to indicate a BCS of an in-band dual connection, the network device can determine the bandwidth of each frequency band supported by the terminal based on the BCS indicated by the first sub-signaling, the third signaling, and the fourth signaling respectively indicated in each frequency band.

[0178] Exemplarily, the network device receives the first information. If the first signaling in the first information indicates that the in-band dual connections are two or three; then the first sub-signaling is used to indicate that the in-band dual connections are two or three, and the BCS supported by the two or three in-band dual connections are the same; then the network device can determine the bandwidth of each frequency band supported by the terminal based on the BCS indicated by the first sub-signaling, the third signaling, and the fourth signaling in each frequency band.

[0179] In some embodiments, when the first information includes the first sub-signaling, the third signaling, and the fourth signaling, the network device configures bandwidth for at least one frequency band supported by the terminal based on the third signaling and the fourth signaling.

[0180] For example, if the terminal supports two or more in-band dual connections, and the first information received by the network device includes the first sub-signaling, the third signaling, and the fourth signaling, but does not include the second sub-signaling, then the network device can only determine the BCS of one of the in-band dual connections supported by the terminal, but cannot determine the BCS of other in-band dual connections; the network device can determine the bandwidth configuration of at least one frequency band supported by the terminal based on the third signaling and the fourth signaling. For example, if the intra-band dual connectivity is DC_3A-41A_n3A-n41A, the BCS0 of DC_3A-41A supported by the terminal may be as shown in Table 3 above, and the BCS0 of CA_n3A-n41A supported by the terminal may be as shown in Table 4 above. The network device may then configure at least one bandwidth of 5 MHz, 10 MHz, 15 MHz, and 20 MHz for frequency band 3 supported by the terminal, at least one bandwidth of 5 MHz, 10 MHz, 15 MHz, and 20 MHz for frequency band 4 supported by the terminal, at least one bandwidth of 5 MHz, 10 MHz, 15 MHz, 20 MHz, 25 MHz, and 30 MHz for frequency band n3 supported by the terminal, and at least one bandwidth of 10 MHz, 15 MHz, 20 MHz, 40 MHz, 50 MHz, 60 MHz, 80 MHz, 90 MHz, and 100 MHz for frequency band n41 supported by the terminal. In this case, the bandwidth of the frequency band supported by the terminal can be determined within a slightly larger frequency range.

[0181] In some optional embodiments, the network device sends second information to the terminal, where the second information is used to indicate the bandwidth configured for at least one frequency band supported by the terminal. In this way, the terminal can be informed of the bandwidth that needs to be configured on the at least one frequency band through the network device.

[0250] The present disclosure relates to an information processing method, which includes:

[0251] In some embodiments, a new signaling is introduced to report the number of intraband dual connectivity pairs supported by the terminal in inter-band (i.e., intra-band) EUTRA-NR dual connectivity. For example, the signaling is NumberOfIntrabandENDCpair-WithInterbandENDC-r18. The signaling can be an enumeration signaling, and the enumeration value can be 2 or 3. For example, when the terminal reports support for DC_XA-YA_nXA-nYA, the number of supported intraband dual connectivity pairs reported through the new signaling is 2.

[0252] Optionally, the signaling 1 may be the first signaling in the previous embodiment; the dual connectivity may be the dual connectivity in the previous embodiment; the intra-band dual connectivity may be the intra-band dual connectivity in the previous embodiment; and an intra-band dual connectivity pair may be an intra-band dual connectivity in the previous embodiment.

[0253] In some embodiments, a new signaling 2 is introduced to report the bandwidth combination sets (BCSs) supported by multiple intra-band dual connectivity pairs, such as signaling 2 is supportedBandwidthCombinationSetIntraENDC-r18xy; this signaling 2 can be extended to multiple entries, such as supportedBandwidthCombinationSetIntraENDC-r18xy, supportedBandwidthCombinationSetIntraENDC-r18xz, etc. For example, when the terminal reports support for two intra-band dual connectivity pairs, the BCS of DC_X_nX is reported through the existing signaling supportedBandwidthCombinationSetIntraENDC, and the BCS of DC_Y_nY is reported through the new signaling 2, where X is less than Y. For example, when the terminal reports support for three intra-band dual connectivity pairs, it reports the BCS of DC_X_nX through the existing signaling supportedBandwidthCombinationSetIntraENDC, and reports the BCS of DC_Y_nY and DC_Z_nZ through the new signaling 2, where X is less than Y and Y is less than Z.

[0254] Optionally, the second signaling may be the second sub-signaling in the previous embodiment; the supportedBandwidthCombinationSetIntraENDC may be the first sub-signaling in the previous embodiment.

[0255] In some embodiments, when the terminal reports the existing signaling supportedBandwidthCombinationSetIntraENDC and the new signaling is a default, it means that the terminal supports one intra-band dual connectivity pair.

[0256] Example 1

[0257] Terminal side: When the terminal reports support for DC_XA_nXA-nYA, it reports the BCS of DC_X_nX through the existing signaling supportedBandwidthCombinationSetIntraENDC, and reports the BCS of NR CA_nXA-nYA through the existing signaling supportedBandwidthCombinationSet, and the new signaling is defaulted. Optionally, supportedBandwidthCombinationSet can be the fourth signaling in the previous embodiment.

[0258] Network device side: If the network device does not receive new signaling and receives the existing signaling supportedBandwidthCombinationSetIntraENDC, it means that the terminal supports an intra-band dual connectivity pair; the network device configures each frequency band supported by the terminal based on the intersection of all reported BCS information on each frequency band.

[0259] Example 2:

[0260] Terminal side: When the terminal reports support for DC_XA-YA_nXA-nYA, it reports the number of supported intra-band dual-link pairs as 2 through the new signaling NumberOfIntrabandENDCpair-WithInterbandENDC-r18, reports the BCS of DC_X_nX through the existing signaling supportedBandwidthCombinationSetIntraENDC, reports the BCS of DC_Y_nY through the new signaling supportedBandwidthCombinationSetIntraENDC-r18, and reports the BCS of the EUTRA CA_XA-YA part and the BCS of the NR CA_nXA-nYA part through the existing signaling supportedBandwidthCombinationSetEUTRA and supportedBandwidthCombinationSet, respectively.
