[0002] Uplink switching in communication technology aims to improve uplink transmission performance through uplink frequency band combinations. This function achieves high- and low-frequency coordination through uplink switching.

[0036] The implementation environment of the embodiments of this disclosure will be introduced below.

[0037] Figure 1 This is a schematic diagram illustrating a communication system according to an exemplary embodiment. For example... Figure 1 As shown, the communication system may include terminal device 101 and network device 102. This communication system can be used to support 4G (4th Generation) network access technologies, such as Long Term Evolution (LTE) access technology, or 5G (5th Generation) network access technologies, such as New Radio Access Technology (New RAT), or other future wireless communication technologies. It should be noted that in this communication system, the number of terminal devices and network devices described above can be one or more. Figure 1The number of terminal devices and network devices in the communication system shown is merely an adaptive example of one embodiment, and this disclosure does not limit it.

[0038] Figure 1 The terminal device in this disclosure can be an electronic device that provides voice or data connectivity, such as a user equipment (UE), subscriber unit, mobile station, or station. For example, the terminal device may include smartphones, smart wearable devices, smart speakers, smart tablets, wireless modems, wireless local loop (WLL) stations, PDAs (Personal Digital Assistants), and CPEs (Customer Premise Equipment). With the development of wireless communication technology, any device that can access a communication system, communicate with network devices within the communication system, or communicate with other objects through the communication system can be a terminal device in this disclosure. Examples include terminals and vehicles in intelligent transportation systems, home appliances in smart homes, electricity meter reading instruments, voltage monitoring instruments, environmental monitoring instruments in smart grids, video monitoring instruments in smart security networks, and cash registers. Figure 1 The illustration uses a mobile phone only. In this embodiment, the terminal device can communicate with a network device, which can be a base station or other network-side equipment. Figure 1 The image shown is only an illustration of a base station.

[0039] In wireless communication systems, for accurate and efficient coordination and interoperability, base stations can grasp all the capabilities of terminal devices. Having grasped these capabilities, the base station can perform accurate scheduling for the terminal devices. If a terminal device supports a certain feature or function, and the base station possesses that function, it should configure it accordingly. In this embodiment, the terminal device can report its uplink switching capability to the network device.

[0040] Figure 2 This is a flowchart illustrating a method for reporting uplink handover capabilities according to an exemplary embodiment, such as... Figure 2 As shown, the method may include:

[0041] S201, Generate capability reporting information. The capability reporting information includes capability indication information for uplink frequency band combinations that can be formed by multiple frequency bands supported by the corresponding terminal device. The uplink frequency band combination includes a first uplink frequency band and a second uplink frequency band. At least one of the first uplink frequency band and the second uplink frequency band is an inter-band carrier aggregation frequency band or a dual-link frequency band. The capability indication information is used at least to indicate the capability information of the terminal device to switch between the first uplink frequency band and the second uplink frequency band included in the uplink frequency band combination.

[0042] In one implementation, in the uplink frequency band combination, the first uplink frequency band is a single frequency band, and the second uplink frequency band is an inter-band carrier aggregation frequency band.

[0043] In one implementation, in the uplink band combination, the first uplink band is a single band, and the second uplink band is a dual-link band.

[0044] In one implementation, in the uplink frequency band combination, both the first uplink frequency band and the second uplink frequency band are inter-band carrier aggregation frequency bands.

[0045] In one implementation, in the uplink band combination, both the first uplink band and the second uplink band are dual-link bands.

[0046] In one implementation, in the uplink frequency band combination, the first uplink frequency band is an inter-band carrier aggregation frequency band, and the second uplink frequency band is a dual-link frequency band.

[0047] Whether a terminal device supports switching between the first uplink band and the second uplink band included in the uplink band combination depends at least partially or entirely on the radio frequency architecture of the terminal device.

[0048] In one possible implementation, the terminal device only sends the capability reporting information if it supports inter-band switching.

[0049] In this embodiment of the disclosure, the terminal device may independently determine the composition of an uplink frequency band combination from multiple frequency bands, or determine the composition of an uplink frequency band combination from multiple frequency bands according to a communication protocol, or compose an uplink frequency band combination from multiple frequency bands according to the configuration of the base station, or compose an uplink frequency band combination from multiple frequency bands according to configuration parameters pre-configured by the terminal device.

[0050] S202, send the capability reporting information to the network device.

[0051] Using the above method, when a terminal device supports three or more frequency bands during uplink, it can generate capability indication information corresponding to multiple uplink frequency band combinations when generating capability reporting information. The uplink frequency band combination refers to various combinations that can be formed from the multiple frequency bands supported by the terminal device. The multiple frequency bands supported by the terminal device and the uplink frequency band combinations that can be formed from these multiple frequency bands can be determined based on the terminal device's own RF architecture. Each uplink frequency band combination includes a first uplink frequency band and a second uplink frequency band, both of which are uplink links. At least one of the first and second uplink frequency bands is an inter-band carrier aggregation band or a dual-link band. The terminal device can determine whether it supports switching between the first and second uplink frequency bands included in the uplink frequency band combination based on its own RF architecture, thereby obtaining capability indication information corresponding to multiple uplink frequency band combinations.

[0052] Among them, at least one of the first uplink frequency band and the second uplink frequency band is an inter-band carrier aggregation frequency band or a dual-link frequency band. Since there are no identical frequency bands in the inter-band carrier aggregation frequency band or the dual-link frequency band, an uplink frequency band combination involves at least three frequency bands, thereby enabling the terminal device to report its ability to switch between three or more frequency bands.

[0053] For example, the first uplink frequency band can be a single frequency band, and the second uplink frequency band can be an inter-band carrier aggregation frequency band or a dual-link frequency band; or, both the first uplink frequency band and the second uplink frequency band can be inter-band carrier aggregation frequency bands or dual-link frequency bands.

[0054] By sending this capability reporting information to the network device, the terminal device enables the network device to know the uplink switching capability of the terminal device, so as to perform corresponding configuration and scheduling.

[0055] In this embodiment, the terminal device can report configuration parameters. These configuration parameters can be sent to the network-side device along with the capability reporting information. In one possible implementation, the configuration parameters may include multiple uplink frequency band combinations determined by the terminal device, and the uplink frequency bands included in each uplink frequency band combination; that is, the terminal device reports multiple uplink frequency band combinations, and the uplink frequency bands in each uplink frequency band combination. In another possible implementation, the configuration parameters may include the uplink frequency bands included in one uplink frequency band combination determined by the terminal device; that is, the terminal device reports only the uplink frequency bands in one uplink frequency band combination.

[0056] Optionally, the capability reporting information may include a bitmap, in which the bits correspond one-to-one with the uplink band combinations that can be formed from multiple frequency bands supported by the terminal device. The bitmap is used to indicate whether the terminal device's uplink band combination supports the capability to switch between frequency bands in the uplink band combination.

[0057] The terminal device can determine whether it supports switching between the first uplink band and the second uplink band included in the uplink band combination based on its own radio frequency architecture. If the terminal device determines that the uplink band combination supports band switching, the bit corresponding to the uplink band combination that supports band switching in the first bit diagram is set to a first value (e.g., 1); if the terminal device determines that the uplink band combination does not support band switching, the bit corresponding to the uplink band combination that does not support band switching in the first bit diagram is set to a second value (e.g., 0). The terminal device sends this first bit diagram to the network device, so that the network device can determine whether the uplink band combination corresponding to the bit supports band switching by using the values ​​of different bits in the first bit diagram.

[0058] In one implementation, the capability reporting information also includes a handover duration, which characterizes the length of time the terminal device spends switching between a first uplink band and a second uplink band in each pair of uplink band combinations that support band switching.

[0059] Assuming the terminal supports m frequency bands, and the first bit of the uplink handover capability report from the terminal to the base station contains n bits with the first value, then n handover durations are reported. These n handover durations correspond one-to-one with the uplink frequency band combinations that support frequency band handover. The signaling format for the handover duration can be designed as (T1, T2, ..., Tn-1), where each bit represents the handover duration of the corresponding uplink frequency band combination that supports frequency band handover.

[0060] In this embodiment, when the terminal device switches between the first uplink frequency band and the second uplink frequency band included in each pair of uplink frequency band combinations that support frequency band switching, the various components of the terminal device need to cooperate and a certain switching time is required. The switching time corresponding to each pair of uplink frequency band combinations that support frequency band switching is used to ensure that the terminal device can successfully complete the switching between the first uplink frequency band and the second uplink frequency band included in the uplink frequency band combination.

[0061] In one implementation, the capability reporting information further includes a second bitmap, where each bit in the second bitmap corresponds one-to-one with a target uplink frequency band combination, which is an uplink frequency band combination that the terminal device supports for frequency band switching. That is, the number of bits in the second bitmap is the same as the number of uplink frequency band combinations that the terminal device supports for frequency band switching, and each bit in the second bitmap corresponds to one uplink frequency band combination that supports frequency band switching. The second bitmap is used to indicate the downlink interruption frequency band in the uplink frequency band combinations that the terminal device supports for frequency band switching.

[0062] In this embodiment of the disclosure, a second bitmap can be used to indicate the downlink interruption band of each of one or more uplink band combinations. For example, when the downlink interruption band in the target uplink band combination is a first uplink band included in the target uplink band combination, the bit in the second bitmap corresponding to the target uplink band combination takes a third value (the third value is, for example, 0); when the downlink interruption band in the target uplink band combination is a second uplink band included in the target uplink band combination, the bit in the second bitmap corresponding to the target uplink band combination takes a fourth value (the fourth value is, for example, 1).

[0063] Downlink interruption occurs because some radio frequency structures share components with the uplink receiving link, such as a shared PLL (Phase Locked Loop). This results in a certain guard interval or downlink interruption time during uplink switching. The terminal device can determine which frequency band the downlink interruption occurs on based on the uplink frequency band combination and radio frequency structure that supports frequency band switching, and report it to the base station.

[0064] The downlink interrupt frequency band of the corresponding uplink band combination that supports frequency band switching is determined by setting different values ​​of the bits in the second bit diagram. When the bit in the second bit diagram is the third value, it indicates that the downlink interrupt corresponding to the target uplink band combination is on the first uplink band. When the bit in the second bit diagram is the fourth value, it indicates that the downlink interrupt corresponding to the target uplink band combination is on the second uplink band. The third value can be 0 and the fourth value can be 1.

[0065] Assuming the terminal supports m frequency bands, and the first bit of the uplink handover capability report from the terminal to the base station contains n 1s, then the second bit contains n bits used to report n downlink interruptions. These n downlink interruptions correspond one-to-one with the uplink frequency band combinations that support frequency band handover; that is, the downlink interruption for each of the n uplink frequency band combinations that support frequency band handover. When a bit in the second bit is 0, the downlink interruption for its corresponding uplink frequency band combination can be on the first uplink frequency band; when a bit in the second bit is 1, the downlink interruption for its corresponding uplink frequency band combination can be on the second uplink frequency band.

[0066] Figure 3 This is a flowchart illustrating a method for generating capability reporting information according to an exemplary embodiment, such as... Figure 3 As shown, in one embodiment, for uplink band combinations composed of multiple frequency bands supported by the terminal device, the first uplink band in each uplink band combination can be a single band, and the second uplink band can be an inter-band carrier aggregation band or a dual-link band, and the first uplink band and the second uplink band do not have overlapping frequency bands. That is, the first uplink band is a single band, the second uplink band is an inter-band carrier aggregation band, and the first uplink band and the second uplink band do not have overlapping frequency bands; or, the first uplink band is a single band, the second uplink band is a dual-link band, and the first uplink band and the second uplink band do not have overlapping frequency bands.

[0067] Generating capability reporting information may include the following steps:

[0068] S301, generating including The first bit diagram, which contains a number of bits, corresponds one-to-one with the uplink frequency band combination.

[0069] Where m represents the number of frequency bands supported by the terminal device, and C represents the combination calculation symbol. The number of combinations that can be obtained by selecting M numbers from N. The calculation method is as follows:

[0070] Where N! represents the factorial calculation of N.

[0071] S302, assign a first value to the bit of the uplink frequency band combination that supports frequency band switching in the first bit diagram, and assign a second value to the bit of the uplink frequency band combination that does not support frequency band switching in the first bit diagram.

[0072] In this embodiment, for multiple frequency bands supported by the terminal device, the first uplink frequency band in each uplink frequency band combination can be a single frequency band, and the second uplink frequency band can be an inter-band carrier aggregation frequency band or a dual-link frequency band. Furthermore, the first uplink frequency band and the second uplink frequency band do not have overlapping frequency bands as the combination target, thus obtaining... For uplink band combinations that can be formed from multiple frequency bands supported by the terminal device, the bits in the first diagram correspond one-to-one with the uplink band combinations. Therefore, the number of bits in the first diagram is the same as the number of uplink band combinations obtained under the current combination target, and can generate combinations including... The first bit diagram contains a number of bits, so that each bit in the first bit diagram corresponds to an uplink frequency band combination.

[0073] Assign a first value to the bit corresponding to the uplink frequency band combination that supports frequency band switching in the first diagram, and assign a second value to the bit corresponding to the uplink frequency band combination that does not support frequency band switching in the first diagram. That is, when the value of the bit in the first diagram is the first value, it indicates that the uplink frequency band combination corresponding to the bit supports frequency band switching, and when the value of the bit in the first diagram is the second value, it indicates that the uplink frequency band combination corresponding to the bit does not support frequency band switching. The first value can be 1 and the second value can be 0.

[0074] Optionally, the multiple frequency bands supported by the terminal device can be numbered, and the numbered frequency bands can be sorted in order of number size. The sorted frequency bands can then be combined in order of the above-mentioned combination target to obtain multiple uplink frequency band combinations.

[0075] For example, assuming the terminal device supports m frequency band combinations, the signaling format when the terminal device reports to the base station whether it supports uplink handover capability can be designed as follows:

[0076] Bitmap = (0,0,0,…,0), where Bitmap is the first bit map. When a bit in the first bit map is 1, it indicates that the corresponding uplink frequency band combination supports frequency band switching, i.e., supports uplink switching. The size of Bitmap (i.e., the number of bits in the first bit map) can be controlled by an array. To determine this, for example, if m = 3, then the size of the Bitmap is...

[0077] Among them, due to therefore therefore

[0078] Taking three bands and the second uplink band as inter-band carrier aggregation bands as an example, the Bitmap size is... Assuming the three bands are arranged in a certain order, such as #0, #1, and #2 bands arranged in ascending order of band number, then uplink switching can be indicated by the corresponding bits in the Bitmap, as follows:

[0079] Bit 0 in the bitmap indicates support for uplink switching between band#0 and band#1 / #2 inter-band CA.

[0080] The first bit in the bitmap indicates that uplink switching between band#1 and band#0 / #2 inter-band CA is supported.

[0081] The second bit in the bitmap indicates that uplink switching between band#2 and band#0 / #1 inter-band CA is supported.

[0082] To facilitate understanding of uplink handover between single-band and carrier aggregation bands by those skilled in the art Figure 6 This diagram illustrates an uplink handover between band#0 and band#1 / #2 inter-band CA.

[0083] Optionally, the capability reporting information also includes the switching duration of the uplink band combinations that support band switching. Taking 3 bands as an example, if the reported Bitmap (first bit) supporting uplink switching capability is (1,0,1), it means that the following uplink band combinations support uplink switching:

[0084] band#0 and band#1 / #2inter-band CA;

[0085] band#2 and band#0 / #1 inter-band CA.

[0086] Accordingly, the reporting switching cycle is (T1, T2), where T1 is the switching duration of band#0 and band#1 / #2 inter-band CA, and T2 is the switching duration of band#2 and band#0 / #1 inter-band CA.

[0087] Optionally, the capability reporting information may also include the frequency band where the downlink interruption occurs.

[0088] Taking 3 bands as an example, if the reported bitmap supporting uplink switching capability is (1,0,1), it means that the following two uplink frequency band combinations support uplink switching:

[0089] band#0 and band#1 / #2inter-band CA;

[0090] band#2 and band#0 / #1 inter-band CA.

[0091] Correspondingly, if the Bitmap reporting downlink interruption is (0,1), then the 0 in the 0th bit can represent that when switching between band#0 and band#1 / #2 inter-band CA, the downlink interruption occurs on a single band#0; the 1 in the 1st bit can represent that when switching between band#2 and band#0 / #1 inter-band CA, the downlink interruption occurs on band#0 / #1 inter-band CA.

[0092] It is worth noting that the above examples are all based on inter-band carrier aggregation. However, those skilled in the art should know that all the inter-band carrier aggregation frequency bands involved in the above examples can also be dual-link frequency bands, such as DC (Dualconnectivity), EN-DC (E-UTRA-NR Dual Connectivity, LTE and NR dual-link), and MR-DC (Multiple Radio DC, multiple radio dual-link), etc.

[0093] The above solution enables the reporting of handover capabilities for single-band and inter-band carrier aggregation bands, or single-band and dual-link bands, when the terminal device supports three or more frequency bands.

[0094] Figure 4 This is a flowchart illustrating another method for generating capability reporting information according to an exemplary embodiment, such as... Figure 4 As shown, in another embodiment, for the uplink band combinations that can be formed by multiple frequency bands supported by the terminal device, the first uplink band and the second uplink band in each uplink band combination have overlapping frequency bands, and the first uplink band and the second uplink band in each uplink band combination are inter-band carrier aggregation bands, or the first uplink band and the second uplink band are dual-link bands, or the first uplink band is a carrier aggregation band and the second uplink band is a dual-link band.

[0095] Generating capability reporting information may include the following steps:

[0096] S401, generating including The first bit diagram contains a number of bits, and the bits in the first bit diagram correspond one-to-one with the uplink frequency band combination.

[0097] Where m is the number of frequency bands supported by the terminal device, and C is the combination calculation symbol.

[0098] S402, assign a first value to the bit of the uplink frequency band combination that supports frequency band switching in the first diagram, and assign a second value to the bit of the uplink frequency band combination that does not support frequency band switching in the first diagram.

[0099] In this embodiment, for multiple frequency bands supported by the terminal device, the combination target is that both the first uplink frequency band and the second uplink frequency band in each uplink frequency band combination are inter-band carrier aggregation frequency bands or both the first uplink frequency band and the second uplink frequency band are dual-link frequency bands, and the first uplink frequency band and the second uplink frequency band have overlapping frequency bands. This yields the following results. For uplink band combinations that can be formed from multiple frequency bands supported by the terminal device, the bits in the first diagram correspond one-to-one with the uplink band combinations. Therefore, the number of bits in the first diagram is the same as the number of uplink band combinations obtained under the current combination target, and can generate combinations including... The first bit diagram has a number of bits, so that each bit in the first bit diagram corresponds to an uplink frequency band combination.

[0100] Assign a first value to the bit corresponding to the uplink frequency band combination that supports frequency band switching in the first diagram, and assign a second value to the bit corresponding to the uplink frequency band combination that does not support frequency band switching in the first diagram. That is, when the value of the bit in the first diagram is the first value, it indicates that the uplink frequency band combination corresponding to the bit supports frequency band switching, and when the value of the bit in the first diagram is the second value, it indicates that the uplink frequency band combination corresponding to the bit does not support frequency band switching. The first value can be 1 and the second value can be 0.

[0101] Optionally, the multiple frequency bands supported by the terminal device can be numbered, and the numbered frequency bands can be sorted in order of number size. The sorted frequency bands can then be combined in order of the above-mentioned combination target to obtain multiple uplink frequency band combinations.

[0102] For example, assuming the terminal device supports m bands, the signaling format when the terminal device reports to the base station whether it supports uplink handover capability can be designed as follows:

[0103] A bitmap is defined as (0,0,0,…,0). When a bit in the bitmap is 1, it indicates that the corresponding combination supports uplink switching. The size of the bitmap can be determined by an array. To determine this, for example, if m = 4, then the size of the Bitmap is...

[0104] Taking 4 bands as an example, the Bitmap size is Assuming the four uplink bands are arranged in a certain order, such as #0, #1, #2, and #3 bands arranged in ascending order of band number, then uplink switching can be indicated by the corresponding bits in the Bitmap, as follows:

[0105] Bit 0 in the bitmap indicates support for uplink switching between band#0 / #1 inter-band CA and band#0 / #2 inter-band CA.

[0106] The first bit in the bitmap indicates that uplink switching between band#0 / #1 inter-band CA and band#0 / #3 inter-band CA is supported.

[0107] The second bit in the bitmap indicates that uplink switching between band#0 / #1 inter-band CA and band#1 / #2 inter-band CA is supported.

[0108] The third bit in the bitmap indicates that uplink switching between band#0 / #1 inter-band CA and band#1 / #3 inter-band CA is supported.

[0109] The 4th bit in the bitmap indicates that uplink switching between band#0 / #2 inter-band CA and band#0 / #3 inter-band CA is supported.

[0110] The 5th bit in the bitmap indicates that uplink switching between band#0 / #2inter-band CA and band#1 / #2inter-band CA is supported.

[0111] The 6th bit in the bitmap indicates that uplink switching between band#0 / #2 inter-band CA and band#2 / #3 inter-band CA is supported.

[0112] The 7th bit in the bitmap indicates that uplink switching between band#0 / #3inter-band CA and band#1 / #3inter-band CA is supported.

[0113] The 8th bit in the bitmap indicates that uplink switching between band#0 / #3inter-band CA and band#2 / #3inter-band CA is supported.

[0114] The 9th bit in the bitmap indicates that uplink switching between band#1 / #2 inter-band CA and band#1 / #3 inter-band CA is supported.

[0115] The 10th bit in the bitmap indicates that uplink switching between band#1 / #2 inter-band CA and band#2 / #3 inter-band CA is supported.

[0116] The 11th bit in the bitmap indicates that uplink switching between band#1 / #3 inter-band CA and band#2 / #3 inter-band CA is supported.

[0117] To facilitate understanding by those skilled in the art of uplink handover between two carrier aggregation bands with overlapping frequency bands Figure 7This diagram illustrates an uplink handover process between band#0 / #1 inter-band CA and band#0 / #2 inter-band CA.

[0118] Optionally, the capability reporting information also includes the switching duration of the uplink band combinations that support band switching. Taking 4 bands as an example, if the reported bitmap supporting uplink switching capability is (1,0,0,0,1,1,0,1,0,0,0,0), it means that the following uplink band combinations support uplink switching:

[0119] uplink switching between band#0 / #1 inter-band CA and band#0 / #2 inter-band CA;

[0120] uplink switching between band#0 / #2 inter-band CA and band#0 / #3 inter-band CA;

[0121] uplink switching between band#0 / #2inter-band CA and band#1 / #2inter-band CA;

[0122] Uplink switching between band#0 / #3inter-band CA and band#1 / #3inter-band CA.

[0123] Accordingly, the reported handover duration is (T1, T2, T3, T4), where T1 is the handover duration for the uplink handover between band#0 / #1 inter-band CA and band#0 / #2 inter-band CA, T2 is the handover duration for the uplink handover between band#0 / #2 inter-band CA and band#0 / #3 inter-band CA, T3 is the handover duration for the uplink handover between band#0 / #2 inter-band CA and band#1 / #2 inter-band CA, and T4 is the handover duration for the uplink handover between band#0 / #3 inter-band CA and band#1 / #3 inter-band CA.

[0124] Optionally, the capability reporting information may also include the frequency band where the downlink interruption occurs.

[0125] Taking 4 bands as an example, if the reported bitmap supporting uplink switching capability is (1,0,0,0,1,1,0,1,0,0,0,0), it means that the following uplink frequency band combinations support uplink switching:

[0126] uplink switching between band#0 / #1 inter-band CA and band#0 / #2 inter-band CA;

[0127] uplink switching between band#0 / #2 inter-band CA and band#0 / #3 inter-band CA;

[0128] uplink switching between band#0 / #2inter-band CA and band#1 / #2inter-band CA;

[0129] Uplink switching between band#0 / #3inter-band CA and band#1 / #3inter-band CA.

[0130] Accordingly, if the Bitmap (second bitmap) reporting the downlink interrupt is (0,1,1,0), then the 0 in the 0th bit can represent that when switching between band#0 / #1 inter-band CA and band#0 / #2 inter-band CA, the downlink interrupt occurs on the preceding band#0 / #1 inter-band CA; the 1 in the 1st bit can represent that when switching between band#0 / #2 inter-band CA and band#0 / #3 inter-band CA, the downlink interrupt occurs on the following band#0 / #3 inter-band CA; the 1 in the 2nd bit can represent that when switching between band#0 / #2 inter-band CA and band#1 / #2 inter-band CA, the downlink interrupt occurs on the following band#1 / #2 inter-band CA; and the 0 in the 3rd bit can represent that when switching between band#0 / #3 inter-band CA and band#1 / #3 inter-band CA, the downlink interrupt occurs on the preceding band#0 / #3 inter-band CA.

[0131] It is worth noting that the above examples are all based on inter-band carrier aggregation. However, those skilled in the art should know that all the inter-band carrier aggregation frequency bands involved in the above examples can also be dual-link frequency bands, such as DC (Dualconnectivity), EN-DC (E-UTRA-NR Dual Connectivity, LTE and NR dual-link), and MR-DC (Multiple Radio DC, multiple radio dual-link), etc.

[0132] The above scheme enables the reporting of handover capabilities for two inter-band carrier aggregation bands with overlapping frequency bands, or two dual-link bands with overlapping frequency bands, or inter-band carrier aggregation bands with overlapping frequency bands and dual-link bands, when the terminal device supports three or more frequency bands.

[0133] Figure 5 This is a flowchart illustrating yet another method for generating capability reporting information according to an exemplary embodiment, such as... Figure 5 As shown, in another embodiment, for the uplink band combinations that can be formed by multiple frequency bands supported by the terminal device, the first uplink band and the second uplink band in each uplink band combination are both inter-band carrier aggregation bands or both are dual-link bands, and the first uplink band and the second uplink band do not have overlapping frequency bands. That is, the first uplink band and the second uplink band are both inter-band carrier aggregation bands, and the first uplink band and the second uplink band do not have overlapping frequency bands; or, the first uplink band and the second uplink band are both dual-link bands, and the first uplink band and the second uplink band do not have overlapping frequency bands.

[0134] Generating capability reporting information may include the following steps:

[0135] S501, generating including The first bit diagram contains a number of bits, and the bits in the first bit diagram correspond one-to-one with the uplink frequency band combination.

[0136] Where m is the number of frequency bands supported by the terminal device, and C is the combination calculation symbol.

[0137] S502, assign a first value to the bit of the uplink frequency band combination that supports frequency band switching in the first diagram, and assign a second value to the bit of the uplink frequency band combination that does not support frequency band switching in the first diagram.

[0138] In this embodiment, for multiple frequency bands supported by the terminal device, the combination target is that both the first uplink frequency band and the second uplink frequency band in each uplink frequency band combination are inter-band carrier aggregation frequency bands or both the first uplink frequency band and the second uplink frequency band are dual-link frequency bands, and the first uplink frequency band and the second uplink frequency band do not have overlapping frequency bands. This yields the following results.

[0139] For uplink band combinations that can be formed from multiple frequency bands supported by the terminal device, the bits in the first diagram correspond one-to-one with the uplink band combinations. Therefore, the number of bits in the first diagram is the same as the number of uplink band combinations obtained under the current combination target, and can generate combinations including... The first bit diagram contains a number of bits, so that each bit in the first bit diagram corresponds to an uplink frequency band combination.

[0140] Assign a first value to the bit corresponding to the uplink frequency band combination that supports frequency band switching in the first diagram, and assign a second value to the bit corresponding to the uplink frequency band combination that does not support frequency band switching in the first diagram. That is, when the value of the bit in the first diagram is the first value, it indicates that the uplink frequency band combination corresponding to the bit supports frequency band switching, and when the value of the bit in the first diagram is the second value, it indicates that the uplink frequency band combination corresponding to the bit does not support frequency band switching. The first value can be 1 and the second value can be 0.

[0141] Optionally, the multiple frequency bands supported by the terminal device can be numbered, and the numbered frequency bands can be sorted in order of number size. The sorted frequency bands can then be combined in order of the above-mentioned combination target to obtain multiple uplink frequency band combinations.

[0142] For example, assuming the terminal device supports m bands, the signaling format when the terminal reports to the base station whether it supports uplink handover capability can be designed as follows:

[0143] A bitmap is defined as (0,0,0,…,0). When a bit in the bitmap is 1, it indicates that the corresponding combination supports uplink switching. The size of the bitmap can be determined by an array. To determine this, for example, if m = 5, then the size of the Bitmap is...

[0144] Taking 5 bands as an example, the Bitmap size is Assuming the five uplink bands are arranged in a certain order, such as #0, #1, #2, #3, and #4 bands arranged in ascending order of band number, then uplink switching can be indicated by the corresponding bits in the Bitmap, as follows:

[0145] Bit 0 in the bitmap indicates support for uplink switching between band#0 / #1 inter-band CA and band#2 / #3 inter-band CA.

[0146] The first bit in the bitmap indicates that uplink switching between band#0 / #1 inter-band CA and band#2 / #4 inter-band CA is supported.

[0147] The second bit in the bitmap indicates that uplink switching between band#0 / #1 inter-band CA and band#3 / #4 inter-band CA is supported.

[0148] The third bit in the bitmap indicates that uplink switching between band#0 / #2 inter-band CA and band#1 / #3 inter-band CA is supported.

[0149] The 4th bit in the bitmap indicates that uplink switching between band#0 / #2 inter-band CA and band#1 / #4 inter-band CA is supported.

[0150] The 5th bit in the bitmap indicates that uplink switching between band#0 / #2 inter-band CA and band#3 / #4 inter-band CA is supported.

[0151] The 6th bit in the bitmap indicates that uplink switching between band#0 / #3 inter-band CA and band#1 / #2 inter-band CA is supported.

[0152] The 7th bit in the bitmap indicates that uplink switching between band#0 / #3 inter-band CA and band#1 / #4 inter-band CA is supported.

[0153] The 8th bit in the bitmap indicates that uplink switching between band#0 / #3 inter-band CA and band#2 / #4 inter-band CA is supported.

[0154] The 9th bit in the bitmap indicates that uplink switching between band#0 / #4 inter-band CA and band#1 / #2 inter-band CA is supported.

[0155] The 10th bit in the bitmap indicates that uplink switching between band#0 / #4 inter-band CA and band#1 / #3 inter-band CA is supported.

[0156] The 11th bit in the bitmap indicates that uplink switching between band#0 / #4 inter-band CA and band#2 / #3 inter-band CA is supported.

[0157] The 12th bit in the bitmap indicates that uplink switching between band#1 / #2 inter-band CA and band#3 / #4 inter-band CA is supported.

[0158] Bit 13 in the bitmap indicates: Support for uplink switching between band#1 / #3 inter-band CA and band#2 / #4 inter-band CA;

[0159] Bit 14 in the bitmap indicates support for uplink switching between band#1 / #4 inter-band CA and band#2 / #3 inter-band CA.

[0160] To facilitate understanding by those skilled in the art of uplink handover between two carrier aggregation bands that do not overlap in frequency bands Figure 8 This diagram illustrates an uplink switching process between band#0 / #1 inter-band CA and band#2 / #3 inter-band CA.

[0161] Optionally, the capability reporting information also includes the switching duration of the uplink band combinations that support band switching. Taking 4 bands as an example, if the reported Bitmap supporting uplink switching capability is (1,0,0,1,1,0,0,0,0,1,0,0,0,1,0), it means that the following uplink band combinations support uplink switching:

[0162] uplink switching between band#0 / #1 inter-band CA and band#2 / #3 inter-band CA;

[0163] uplink switching between band#0 / #2 inter-band CA and band#1 / #3 inter-band CA;

[0164] uplink switching between band#0 / #2 inter-band CA and band#1 / #4 inter-band CA;

[0165] uplink switching between band#0 / #4 inter-band CA and band#1 / #2 inter-band CA;

[0166] Uplink switching between band#1 / #3 inter-band CA and band#2 / #4 inter-band CA.

[0167] Correspondingly, the reported handover duration is (T1, T2, T3, T4, T5), where T1 is the handover duration for the uplink handover between band#0 / #1 inter-band CA and band#2 / #3 inter-band CA, T2 is the handover duration for the uplink handover between band#0 / #2 inter-band CA and band#1 / #3 inter-band CA, T3 is the handover duration for the uplink handover between band#0 / #2 inter-band CA and band#1 / #4 inter-band CA, T4 is the handover duration for the uplink handover between band#0 / #4 inter-band CA and band#1 / #2 inter-band CA, and T5 is the handover duration for the uplink handover between band#1 / #3 inter-band CA and band#2 / #4 inter-band CA.

[0168] Optionally, the capability reporting information may also include the frequency band where the downlink interruption occurs.

[0169] Taking 4 bands as an example, if the reported bitmap supporting uplink switching capability is (1,0,0,1,1,0,0,0,0,1,0,0,0,1,0), it means that the following uplink frequency band combinations support uplink switching:

[0170] uplink switching between band#0 / #1 inter-band CA and band#2 / #3 inter-band CA;

[0171] uplink switching between band#0 / #2 inter-band CA and band#1 / #3 inter-band CA;

[0172] uplink switching between band#0 / #2 inter-band CA and band#1 / #4 inter-band CA;

[0173] uplink switching between band#0 / #4 inter-band CA and band#1 / #2 inter-band CA;

[0174] Uplink switching between band#1 / #3 inter-band CA and band#2 / #4 inter-band CA.

[0175] Accordingly, if the Bitmap (second bitmap) reporting a downlink interrupt is (0,1,1,0,0), then the 0 in bit 0 can represent that when switching between band#0 / #1 and band#2 / #3 inter-band CA, the downlink interrupt occurs on the preceding band#0 / #1 inter-band CA; the 1 in bit 1 can represent that when switching between band#0 / #2 and band#1 / #3 inter-band CA, the downlink interrupt occurs on the following band#1 / #3 inter-band CA; the 1 in bit 2 can represent that when switching between band#0 / #2 and band#1 / #4 inter-band CA, the downlink interrupt occurs on the following band#1 / #4 inter-band CA; the 0 in bit 3 can represent that when switching between band#0 / #4 and band#1 / #2 inter-band CA, the downlink interrupt occurs on the preceding band#0 / #4 inter-band CA; and the 0 in bit 4 can represent that when switching between band#1 / #3 and band#2 / #4 inter-band CA... During CA switching, downlink interruption occurs on the preceding band#1 / #3 inter-band CA.

[0176] It is worth noting that the above examples are all based on inter-band carrier aggregation. However, those skilled in the art should know that all the inter-band carrier aggregation frequency bands involved in the above examples can also be dual-link frequency bands, such as DC (Dualconnectivity), EN-DC (E-UTRA-NR Dual Connectivity, LTE and NR dual-link), and MR-DC (Multiple Radio DC, multiple radio dual-link), etc.

[0177] The above scheme enables the reporting of handover capabilities for two inter-band carrier aggregation bands without repeating frequency bands, or two dual-link frequency bands without repeating frequency bands, or inter-band carrier aggregation bands without repeating frequency bands and dual-link frequency bands, when the terminal device supports four or more frequency bands.
