[0022] To facilitate a clearer understanding of the technical concepts presented in each embodiment of this application, some relevant background information is introduced below.

[0023] The UL Tx switching mechanism allows a single UE to transmit simultaneously with up to two Tx signals, with one carrier supporting one UL Tx (Carrier 1) and another carrier supporting two UL Tx signals (Carrier 2). Carrier 1 and Carrier 2 are on different bands, and switching between Tx signals supports switching between two modes: Mode 1: Uplink dual-stream transmission on Carrier 2, and Mode 2: Single-stream transmission on Carrier 1 and / or Carrier 2.

[0024] Based on whether or not carrier 1 and carrier 2 support simultaneous uplink transmission, the options are divided into option 1 (where the upper-layer parameter uplinkTxSwitchingOption-r16 set by the network is switchedUL, indicating that carrier 1 and carrier 2 cannot perform uplink transmission simultaneously) and option 2 (where the upper-layer parameter uplinkTxSwitchingOption-r16 set by the network is dualUL, indicating that carrier 1 and carrier 2 can perform uplink transmission simultaneously).

[0025] The UE reports its capabilities and the support status for Option 1, Option 2, or both Option 1 and Option 2 for each frequency band combination (Per Band Combination, Per BC). It also reports the time required for UL Tx switching for each frequency band pair (Per band pair) as the switching period.

[0026] The network sets upper-layer parameters to specify the support status for option1 or option2 per cell group. For each serving cell, it sets whether the UL Tx switching period is in this cell and whether this cell is carrier1 or carrier2.

[0027] Related technologies further extend the switching conditions for inter-band aggregation carriers (inter-CA) and supplementary uplinks (SUL). When both carriers support two Tx, 2Tx-2Tx switching is supported. Furthermore, switching between having one carrier on band A and two carriers on band B (these two carriers may transmit with the same Tx) is supported. Two new RRC parameters are also introduced: one parameter indicates whether the switching mode is 1Tx-2Tx or 2Tx-2Tx, and, if the Tx state after UL Tx switching is not unique, the other parameter indicates whether there is one Tx on each carrier or two Tx on a single carrier.

[0028] When Tx 1 switches from band A to band B and Tx 2 remains in band C, in addition to adhering to the basic terminal assumption (i.e., neither Tx can transmit on band C during the switching period), we agree to an additional terminal capability, namely supporting that Tx 2 can perform uplink transmission on band C during the switching period (additional terminal capability 1). Furthermore, the granularity of this additional terminal capability can be based on at least two options: per band pair per BC / per band per band pair per BC / without excluding other options simultaneously.

[0029] On the other hand, when two transmission channel chains (Tx chains) are each switched with two different band pairs and correspond to different switching periods, for example, the switching time for Tx 1 is Tswitch_1, the switching time for Tx 2 is Tswitch_2, and Tswitch_1 < Tswitch_2, there may be two options for consideration as follows: Option1: Based on the basic UE assumptions, further selective UE capabilities (additional terminal capabilities 2) are introduced to allow Tx1 to be used for transmission within the time of (Tswitch_2 - Tswitch_1). It is assumed that the basic UE does not allow Tx1 and Tx2 to be used for transmission within the time of Tswitch_1. The further selective UE capabilities may include, but are not limited to, the per band pair per BC option.

[0030] Option2: No further selective UE capabilities are introduced.

[0031] To sum up, in the related art, since there is no further discussion and conclusion on the detailed understanding of each option of the additional capabilities that the terminal can select, the terminal and the network-side device have inconsistent understandings regarding the UL Tx switching behavior, and a situation where uplink transmission errors of the terminal occur.

[0032] Therefore, in order to enable the terminal and the network-side device to have a consistent understanding of the UL Tx switching behavior corresponding to the UE and improve the uplink transmission efficiency of the terminal, the embodiments of the present application provide an information reporting method, apparatus, and terminal.

[0033] Hereinafter, the information reporting method according to the embodiments of the present application will be described in detail by several embodiments and their application scenarios in conjunction with the drawings.

[0034] Figure 2 is a flowchart of one of the information reporting methods according to an embodiment of the present application, and as shown in Figure 2, the method includes step 201, where In step 201, the terminal reports first information to the network-side device, and the terminal includes a first Tx and a second Tx, where the first information is: A first capability, used to instruct the terminal to support the second Tx performing uplink transmission within a first switching cycle, wherein the first switching cycle is the switching cycle corresponding to the target band pair where the first Tx is located when it performs uplink Tx switching, The second capability includes at least one of the following: a second capability used to instruct the terminal to support the first Tx performing uplink transmission within a first time period, wherein the first time period is the difference between a third switching period and a second switching period, the third switching period is the switching period corresponding to the second band pair where the second Tx is located when it performs uplink switching, and the second switching period is the switching period corresponding to the first band pair where the first Tx is located when it performs uplink switching. The first capability is reported based on the target band pair information, at least one band information in the target band pair including the first band, identifier information for the first band, target band list information, and BC information, wherein the first band is the band before the first Tx performs an uplink Tx switchover, or the first band is the band after the first Tx performs an uplink Tx switchover. The second capability is reported based on at least one of the first band pair information and the second band pair information.

[0035] It should be noted that the embodiments of this application can be applied to a scenario of uplink transmission for a terminal. The terminal includes, but is not limited to, the types of terminals 11 listed above, and the first network-side equipment includes, but is not limited to, the types of network-side equipment 12 listed above.

[0036] In the embodiments of this application, the terminal reports first information to the network-side equipment, enabling the network-side equipment to have a consistent understanding of the terminal and UL Tx switching behavior based on the first information, and further improving the uplink transmission efficiency of the terminal.

[0037] The first piece of information includes at least one of the terminal's first and second capabilities, and the terminal must report its first and second capabilities based on resources of different reporting granularity, where the resources of different reporting granularity correspond to the terminal's different UL Tx switching behaviors.

[0038] Accordingly, the granularity of the terminal's reporting capabilities differs, and the signaling of the primary information also differs.

[0039] For example, if a terminal reports a first capability based on target band pair information, the signaling of the first information can be expressed as follows: ULTxSwitchingBandPair::= SEQUENCE { bandIndexUL1 INTEGER(1..maxSimultaneousBands), bandIndexUL2 INTEGER(1..maxSimultaneousBands), uplinkTxSwitchingPeriod-r16 ENUMERATED {n35us, n140us, n210us}, additionalcapability1_r18} When a terminal reports a first capability based on band information of at least one of the target band pairs, at least one band includes a first band, the first band being the band before the first Tx performs an uplink Tx switch, or the first band being the band after the first Tx performs an uplink Tx switch, and the first band may be defined by the protocol.

[0040] The signaling of the first piece of information can be expressed as follows: ULTxSwitchingBandPair ::= SEQUENCE { bandIndexUL1 INTEGER(1..maxSimultaneousBands), bandIndexUL2 INTEGER(1..maxSimultaneousBands), uplinkTxSwitchingPeriod-r16 ENUMERATED {n35us, n140us, n210us}, additionalcapability1_r18 ENUMERATED {bandIndexUL1, bandIndexUL2}} If a terminal reports a first capability based on the identifier information of a first band pair, the signaling of the first information can be expressed as follows: Band 1::= SEQUENCE { bandIndexUL1 INTEGER(1..maxSimultaneousBands), additionalcapability1_r18} When a terminal reports a second capability based on first and second band pair information, the signaling of the first information can be expressed as follows: ULTxSwitchingBandPair-r16 ::= SEQUENCE { bandIndexUL1-r16 INTEGER(1..maxSimultaneousBands), bandIndexUL2-r16 INTEGER(1..maxSimultaneousBands), uplinkTxSwitchingPeriod-r16 ENUMERATED {n35us, n140us, n210us}, additionalcapability2_r18} It should be explained that the first or second ability (i.e., the signaling of the additional ability) may be the same as or different from the signaling of the base ability, and the signaling of the first and second abilities may be the same as or different from the signaling of the base ability.

[0041] In the embodiments of this application, the terminal reports its capabilities to network-side equipment based on resources of different reporting granularity, namely, the terminal reports a first capability to network-side equipment based on target band pair information, band information of at least one frequency band in the target band pair, identifier information of the first band, target band list information, and BC information, instructing the terminal to support uplink transmission of the second Tx within a first switching cycle, and reports a second capability to network-side equipment based on the first band pair information and the second band pair information, instructing the terminal to support uplink transmission of the first Tx within a first time period, thereby enabling the terminal's different reporting granularity to correspond to different UL Tx switching behaviors, thereby allowing the terminal and network-side equipment to have a consistent understanding of the terminal's UL Tx switching behavior and improving the terminal's uplink transmission efficiency.

[0042] Selectively, different reporting granularities of terminals correspond to different UL Tx switching behaviors, and the methods by which terminals report primary capabilities to network-side devices for resources with different reporting granularities include at least one of the following: When a terminal reports a first capability based on each frequency band pair (per band pair per BC) in each combination of frequency bands, that is, when a terminal reports a first capability based on target band pair information in a target BC, the method by which the terminal reports the first capability includes the following methods 1-2, where per BC may be a selective feature.

[0043] In method 1, when reporting the first capability based on the target band pair information, if the first Tx performs an uplink Tx switch within the target band pair, the terminal uses the second Tx to perform uplink transmission on a third band other than the target band pair within the first switching cycle.

[0044] In other words, if a target band pair on a certain BC reports a first capability, or if the first capability corresponds to at least one target band pair, and one Tx (e.g., the first Tx, also called Tx1) performs an uplink Tx switch within the target band pair (e.g., band A and band B) (i.e., Tx1 switches from one band of the target band pair to another), then if another Tx (e.g., the second Tx, also called Tx2) is on a band other than this target band pair (e.g., a third band), then Tx2 may perform uplink transmission on the third band during the Tx1 switching period (or the switching period corresponding to the target band pair), meaning that Tx2 is not affected by the Tx1 switch.

[0045] For example, if the target band pair includes band A + band B and reports primary capability for band A + band B, then when Tx1 switches from band A to band B or from band B to band A, Tx2 can perform uplink transmission on band C during Tx1's switching period.

[0046] The signaling by which a terminal reports its primary capability can be expressed as follows: ULTxSwitchingBandPair::= SEQUENCE { band A, band B, additionalcapability1_r18 } Figure 3 is one schematic diagram of Tx switching according to an embodiment of the present application. As shown in Figure 3(a), the band pair includes band A and band B. Tx1 switches from band A to band B, and the switching period for Tx1 is T_switch1. Tx2 is in band C and can perform uplink transmission within T_switch1.

[0047] As shown in Figure 3(b), the band pair includes band A and band B. Tx1 switches from band B to band A, and the switching period for Tx1 is T_switch1. Tx2 is in band C and can perform uplink transmission within T_switch1.

[0048] Reporting primary capabilities to network-side devices based on Method 1 is relatively easy for terminals to implement.

[0049] In method 2, when reporting the first capability based on the target band pair information, if the first Tx performs an uplink Tx switch between the first band in the target band pair and a third band other than the target band pair, the terminal uses the second Tx to perform uplink transmission on the second band in the target band pair within the first switching cycle.

[0050] In other words, when a target band pair on a certain BC reports a first capability, or when the first capability corresponds to at least one target band pair, and one Tx (e.g., Tx1) performs an uplink Tx switch between one band (band A) in the target band pair and a band other than the target band pair (i.e., a third band, e.g., band C) (the one band includes the band before or after the switch for band A), if Tx2 is on band B in the target band pair, Tx2 may perform uplink transmission on band B during the Tx1 switchover period.

[0051] For example, if the target band pair includes band A and band B, and primary capability is reported for band A and band B, Tx1 will switch from band A to band C (excluding band B), and Tx2 will be able to perform uplink transmission in band B within the switching time of Tx1.

[0052] The signaling by which a terminal reports its primary capability can be expressed as follows: ULTxSwitchingBandPair::= SEQUENCE { band A, band B, additionalcapability1_r18 band A, } Figure 4 is a schematic diagram of Tx switching according to an embodiment of the present application, and as shown in Figure 4(a), the band pair includes band A + band B, Tx1 switches from band A to band C, the switching period for Tx1 is T_switch1, Tx2 is in band B and can perform uplink transmission within T_switch1.

[0053] As shown in Figure 4(b), the band pair includes band A and band B. Tx1 switches from band C to band A, and the switching period for Tx1 is T_switch1. Tx2 is in band B and can perform uplink transmission within T_switch1.

[0054] Based on method 2, the primary capability is reported to the network-side equipment, and for a band participating in Tx switching, the band to be used for uplink transmission can be determined. However, the Tx switching time varies depending on the band pair participating in the switching, which increases the complexity of the terminal to some extent.

[0055] The method by which a terminal reports a first capability based on each frequency band of each frequency band pair in each combination of frequency bands (per band per band pair per BC), that is, when a terminal reports a first capability based on the information of at least one band among the target band pairs in the target BC, includes the following methods 3-4, where per BC may be a selective feature.

[0056] In method 3, when the first capability is reported based on the target band pair information and the band information of at least one of the target band pairs, if the first Tx performs an uplink Tx switch within the target band pair, the terminal uses the second Tx to perform uplink transmission on a third band other than the target band pair within the first switching cycle.

[0057] In other words, if a band in a target band pair of a certain BC reports a first capability, or if the first capability corresponds to at least one band, when one Tx (e.g., Tx1) switches on a band within the target band pair (for example, this band is the first band, and the first band may be the band before and / or after the switch), if another Tx (e.g., Tx2) is on a band other than this target band pair (i.e., a third band, e.g., band C), Tx2 may perform uplink transmission on band C during the Tx1 switchover period.

[0058] For example, if the target band pair includes band A and band B, and the primary capability is reported for band A in the target band pair, when Tx1 switches between band A and band B (including cases where Tx1 switches from band A to band B, or Tx1 switches from band B to band A), Tx2 can perform uplink transmission in band C within the switching time of Tx1.

[0059] It should be explained that the difference between Method 3 and Method 1 is that in Method 3, at least one band within the target band pair includes the first band, and the first band is either the band before the uplink Tx switchover or the band after the uplink Tx switchover. The first band may be determined by one of the following methods: protocol specification, instructions in terminal capability reporting, and base station configuration.

[0060] In method 4, when reporting the first capability based on the target band pair information and the first band information in the target band pair, if the first Tx performs an uplink Tx switch between the first band in the target band pair and a third band other than the target band pair, the terminal uses the second Tx to perform uplink transmission on the second band in the target band pair within the first switching cycle.

[0061] In other words, if a band in a target band pair of a certain BC reports a first capability, or if the first capability corresponds to at least one band, and when one Tx (Tx1) performs an uplink Tx switch between the first band (e.g., band A) within this target band pair and a band outside the target band pair (e.g., a third band), if Tx2 is on band B within the target band pair, Tx2 may perform uplink transmission on band B during the Tx1 switchover period.

[0062] For example, if the target band pair includes band A and band B, and the primary capability is reported for band A in the target band pair, when Tx1 switches between band A and band C (for example, when Tx1 switches from band A to band C, or when Tx1 switches from band C to band A), Tx2 can perform uplink transmission in band B within the switching time of Tx1.

[0063] One point to explain is that the difference between Method 4 and Method 2 is that in Method 4, the first band may be determined to be a band in the target band pair by any one of the following methods: protocol specification, instructions in terminal capability reporting, and base station configuration.

[0064] When a terminal reports a first capability based on each frequency band in each combination of frequency bands (per band per BC), that is, when a terminal reports a first capability based on identifier information of the first band in the target BC, the method by which the terminal reports the first capability includes the following method 5, where per BC may be a selective feature.

[0065] In method 5, when reporting the first capability based on the identifier information of the first band, if the first Tx performs an uplink Tx switch on the first band, the terminal uses the second Tx to perform an uplink transmission on the third band within the first switching cycle, and the third band is different from the band where the first Tx is located when it performs the uplink Tx switch.

[0066] In other words, when a first band of a certain BC reports a first capability, and one Tx (e.g., Tx1) performs a switch on this first band (including Tx1 switching from another band (also called a target band) to this first band, or Tx1 switching from this first band to another band), if another Tx (e.g., Tx2) is on another band other than the two bands mentioned above (e.g., a third band), Tx2 may perform uplink transmission on the third band during the Tx1 switchover period.

[0067] Selectively, the target band is any band that can be switched between the first band and the Tx band.

[0068] Selectively, the target band is a specific band on which a Tx switch can be performed with the first band, and this specific band may be defined by the protocol, for example, the band on which PUCCH is located.

[0069] Reporting the first capability based on Method 5 is an implementation method that is flexible, but the implementation complexity of the terminal is high.

[0070] When a terminal reports a first capability based on a per-band list per BC for each combination of frequency bands, that is, when a terminal reports a first capability based on target band list information in a target BC, the method by which the terminal reports the first capability includes the following method 6, where the target band list includes at least one band, for example, the target band list includes three or four bands, and per BC may be a selective feature.

[0071] In method 6, when reporting the first capability based on the target band list information, if the first Tx performs an uplink Tx switch on any one of the bands in the target band list, the terminal uses the second Tx to perform uplink transmission on the third band within the first switching cycle, and the third band is different from the band where the first Tx is located when it performs the uplink Tx switch.

[0072] In other words, if a certain band list of a certain BC reports a first capability, and one Tx (e.g., Tx1) performs a switch on this target band list (including Tx1 switching from another band to a band on this target band list, or switching from a band on this target band list to another band), and another Tx (e.g., Tx2) is on another band other than the two bands mentioned above (e.g., a third band), then Tx2 may perform uplink transmission on the third band during the Tx1 switchover period.

[0073] When a terminal reports a first capability based on a combination of frequency bands (per BC), that is, when a terminal reports a first capability based on BC information, the method by which the terminal reports the first capability includes the following method 7: In method 7, when reporting the first capability based on the BC information, if the first Tx performs an uplink Tx switch on any one band in the BC, the terminal uses the second Tx to perform uplink transmission on the third band within the first switching cycle, and the third band is different from the band where the first Tx is located when it performs the uplink Tx switch.

[0074] In other words, when Tx1 switches from one band in BC to another, or from another band to one band in BC, the terminal uses Tx2 to perform uplink transmission on the third band during the Tx1 switching period. That is, performing uplink transmission on the third band is not affected by other Tx switching.

[0075] When a terminal reports a first capability based on each terminal (per UE), the method by which the terminal reports the first capability includes the following method 8: In method 8, when the first Tx performs an uplink Tx switch on any one band corresponding to the terminal, the terminal uses the second Tx to perform uplink transmission on a third band within the first switching cycle, and the third band is different from the band where the first Tx is located when it performs the uplink Tx switch.

[0076] Terminal capability reporting granularity, based on per BC or per UE, is larger in granularity but can lead to increased implementation complexity in key areas.

[0077] Selectively, the third band is a) Bands other than the target band pair, b) A specific band and c) Bands defined by the protocol, d) Including one of the target band pair and the band to be bound, as reported by the terminal.

[0078] In the above embodiment, the terminal reports the first capability based on different reporting granularities, whereby the terminal and the network-side device have a consistent understanding of the UL Tx switching behavior of the terminal, avoid uplink transmission errors, and thereby improve the uplink transmission efficiency of the terminal.

[0079] Optionally, when two Tx chains perform switching with two different band pairs respectively and correspond to different switching periods, for example, the switching time for Tx1 is Tswitch_1, the switching time for Tx2 is Tswitch_2, and Tswitch_1 < Tswitch_2, the second capability of the terminal may be represented in any one of the following ways: a) The second capability means that the terminal is permitted to use Tx1 for transmission within the time of (Tswitch_2 - Tswitch_1).

[0080] b) The second capability means that neither Tx1 nor TX2 can be used for transmission within the time of (Tswitch_1).

[0081] c) Each Tx follows the switching period of the band pair corresponding to its switching, or each Tx cannot transmit within the switching period of the band pair corresponding to its switching, that is, Tx1 cannot transmit within the time of Tswitch_1, that is, Tx2 cannot transmit within the time of Tswitch_1.

[0082] The different reporting granularities of the terminal correspond to different UL Tx switching behaviors. For resources with different reporting granularities, the ways for the terminal to report the second capability to the network-side device include at least one of the following: In method [1], when reporting the second capability based on the first band pair information and the second band pair information, the terminal performs uplink transmission within the first time period using the first Tx.

[0083] That is, when both of the two band pairs (the first band pair and the second band pair) have the second capability, the terminal permits the Tx1 to be used for uplink transmission within the time of (Tswitch_2 - Tswitch_1).

[0084] In method [2], when reporting the second capability based on the first band pair information, the terminal performs uplink transmission within the first time period using the first Tx.

[0085] That is, when the first band pair has the second capability, the second band pair does not have the second capability, or the second band pair has terminal capability 0, and when the switching period of the first band pair is smaller than that of the second band pair (Tswitch_1 < Tswitch_2), the Tx1 (the Tx within the first band pair) is used for uplink transmission within the time of (Tswitch_2 - Tswitch_1).

[0086] It should be noted that the terminal capability 0 means that both of the two Tx's in the second band pair switch according to a longer time (greater than Tswitch_2).

[0087] In method [3], when not reporting the second capability based on the first band pair information or the second band pair information, the terminal does not permit performing uplink transmission within the first time period using the first Tx.

[0088] In other words, if at least one of the two band pairs does not possess the second capability, the terminal will not allow Tx1 to be used for uplink transmission within (Tswitch_2 - Tswitch_1) time.

[0089] Selectively, in the above embodiment, the transmission within the time (Tswitch_2-Tswitch_1) is a specific channel / signal, such as a Physical Uplink Control Channel (PUCCH) / Sounding Reference Signal (SRS).

[0090] Selectively, the terminal using the first Tx to perform uplink transmission within the first time period can be achieved by the following steps: This includes, if the target conditions are met, the terminal using the first Tx to perform an uplink transmission within the first time period, The aforementioned target conditions are: a) The third switching period and the second switching period overlap at least partially in the time domain, b) The first band pair and the second band pair both include a fourth band, and the positions of the third switching period and the second switching period are both set on the fourth band, at least one of these.

[0091] In the above embodiment, the terminal reports a second capability based on different reporting granularity, thereby enabling the terminal and network-side equipment to have a consistent understanding of the terminal's UL Tx switching behavior, avoiding uplink transmission errors, and thereby improving the terminal's uplink transmission efficiency.

[0092] Selectively, when the first and second Tx of the terminal switch from the third band pair uplink Tx to the fourth band pair, and the third band pair includes the fifth and seventh bands, and the fourth band pair includes the sixth and seventh bands, that is, when the terminal's Tx2 and Tx1 switch from the (band A + band C) uplink to (band B + band C), the terminal determines, based on the target scheme, at least one of the following, including the path by which the terminal performs the uplink Tx switching, or the time by which the terminal interrupts / switches the uplink transmission, where: a) The terminal performs an uplink Tx switch based on a first path, the first path being used to instruct the first Tx to switch from the fifth band to the seventh band within the third band pair, and the second Tx to switch from the seventh band to the sixth band within the fourth band pair.

[0093] For example, if the third band pair includes (band A + band C) and the fourth band pair includes (band B + band C), the first path is used to indicate that Tx1 switches from band A to band C and Tx2 switches from band C to band B.

[0094] b) The terminal performs an uplink Tx switch based on a second path, the second path being used to instruct the first Tx to switch from the fifth band in the third band pair to the sixth band in the fourth band pair, and the second Tx is maintained on the seventh band.

[0095] For example, the third band pair includes (band A + band C), the fourth band pair includes (band B + band C), and the second path is used to indicate that Tx1 switches from band A to band B and Tx2 remains in band C.

[0096] c) Uplink transmissions of the fifth band, the sixth band, and the seventh band are all interrupted within the time of the target switching cycle, or the terminal does not perform uplink transmission within the time of the target switching cycle.

[0097] For example, if the third band pair includes the fifth band (band A) and the seventh band (band C), and the fourth band pair includes the sixth band (band B) and the seventh band (band C), then the uplink transmissions for bands A, B, and C will all be interrupted during the target switching cycle, or the terminal will not expect to perform uplink transmissions within the target switching cycle.

[0098] Here, the target switching period is the maximum value of the fourth switching period and the fifth switching period, the fourth switching period is the switching period corresponding to the third band pair, and the fifth switching period is the switching period corresponding to the fourth band pair. Specifically, the target switching period may be expressed as max(T1,T2).

[0099] d) Uplink transmissions of the fifth band, the sixth band, and the seventh band are all interrupted within the time of the fourth switching cycle, or the terminal does not perform uplink transmissions within the time of the fourth switching cycle, or the terminal performs uplink transmissions within the second time period.

[0100] For example, if the third band pair includes the fifth band (band A) and the seventh band (band C), and the fourth band pair includes the sixth band (band B) and the seventh band (band C), then the uplink transmissions of bands A, B, and C may all be interrupted within the time period (T1) of the fourth switching cycle, or the terminals may not transmit (or do not expect to transmit) within the time period T1, and Tx2 may be used for uplink transmission within the second time period.

[0101] Here, the second time period is the time period corresponding to the difference between the fifth switching cycle and the fourth switching cycle, and specifically, the second time period may be expressed as being used for uplink transmission within the time period T2-T1 (when T2>T1).

[0102] e) Uplink transmissions of the fifth band, the sixth band, and the seventh band are all interrupted within the time of the sixth switching cycle, or the terminal does not perform uplink transmission within the time of the sixth switching cycle.

[0103] For example, the third band pair includes the fifth band (band A) and the seventh band (band C), and the fourth band pair includes the sixth band (band B) and the seventh band (band C). Uplink transmissions for bands A, B, and C are all interrupted within the time of the sixth switching cycle, or the terminals do not perform (do not expect to perform) uplink transmissions within the time of the sixth switching cycle.

[0104] Here, the sixth switching period is the switching time period in which the first Tx switches from the fifth band in the third band pair to the sixth band in the fourth band pair, and can be represented by T3.

[0105] f) Uplink transmissions of both the fifth band and the sixth band are interrupted within the time of the sixth switching cycle, or the terminal does not perform uplink transmissions within the time of the sixth switching cycle, or the terminal performs uplink transmissions within the sixth switching cycle.

[0106] For example, the third band pair includes the fifth band (band A) and the seventh band (band C), the fourth band pair includes the sixth band (band B) and the seventh band (band C), and the uplink transmissions of band A and band B are both interrupted within the time of the sixth switching cycle (T3), or the terminals do not perform (do not expect to perform) uplink transmissions within the time of T3, and Tx2 may be used for uplink transmissions within the time of T3.

[0107] In the above embodiment, the terminal can determine the path for performing uplink Tx switching, or the time for the terminal to interrupt / switch uplink transmission, based on the target scheme, and report this to the network-side equipment. This allows the terminal and the network-side equipment to have a consistent understanding of the terminal's UL Tx switching behavior, avoiding uplink transmission errors and thereby improving the terminal's uplink transmission efficiency.

[0108] Selectively, the target scheme is a) The implementation method of the terminal, b) The reporting method of the terminal, c) UE capability reporting method and d) Includes at least one of the predefined rules.

[0109] Selectively, if the target scheme includes the UE capability reporting scheme and the terminal reports the first capability to the network-side equipment, the terminal decides to perform an uplink Tx switch based on the second path. For example, when a terminal reports a first capability to network-side equipment, the terminal decides to perform an uplink Tx switch based on a second path, based on the UE capability reporting scheme. That is, the third band pair includes (band A + band C), the fourth band pair includes (band B + band C), and the second path is used to instruct that Tx1 switches from band A to band B and Tx2 remains on band C.

[0110] Accordingly, both band A and band B will interrupt transmission according to max(T1,T2,T3), while band C will transmit only according to Tx2 terminals.

[0111] Or, If the target scheme includes the UE capability reporting scheme and the terminal reports the second capability to the network-side equipment, the terminal decides to perform an uplink Tx switch based on the first path.

[0112] For example, when a terminal reports a second capability to network-side equipment, the terminal decides, based on the UE capability reporting scheme, to perform an uplink Tx switch based on the first path, i.e., the third band pair includes (band A + band C), the fourth band pair includes (band B + band C), and the first path is used to instruct that Tx1 switches from band A to band C and Tx2 switches from band C to band B.

[0113] Accordingly, both band A and band B will interrupt transmission according to max(T1,T2,T3), while band C will transmit only according to the Tx1 terminal.

[0114] It should be explained that if the target scheme includes the UE capability reporting scheme and the terminal has not reported the first or second capability to the network-side equipment, the terminal may determine the time for interrupting / switching uplink transmission by the following scheme:

[0115] a) When the third band pair includes the fifth band (band A) and the seventh band (band C), and the fourth band pair includes the sixth band (band B) and the seventh band (band C), the uplink transmissions of bands A, B, and C are all interrupted within the time of max(T1,T2).

[0116] b) Uplink transmissions for bands A, B, and C are all interrupted within time T3, or the terminal does not perform uplink transmissions within the time of the sixth switching cycle.

[0117] In the above case, the terminal does not need to distinguish the path for switching the uplink Tx, and may decide based on the implementation, by applying a) or b), or by linking it with network parameter settings or predefined rules.

[0118] Selectively, the aforementioned predefined rules include at least one of the following: a) The correspondence between the second path and the first scenario, wherein the interruption time or switching time when the terminal performs an uplink Tx switch based on the second path is related to the first capability, where the first scenario includes at least one of the following: the first Tx and second Tx of the terminal switch from the third band pair uplink Tx to the fourth band pair; the network-side equipment schedules transmission on the sixth band; the RRC parameter setting is that the two Tx are on different bands; and the associated band of the sixth band is the seventh band.

[0119] If the predefined rules include a correspondence between the second path and the first scenario, the first scenario is, for example, that the third band pair includes band A + band C, the fourth band pair includes band B + band C, terminal Tx2 and Tx1 switch from the uplink Tx of the third band pair to the fourth band pair, the network-side equipment schedules a 1-port transmission on band B, the RRC parameter is set to oneT, and the associated band of band B is band C.

[0120] In the above case, the interruption time or switching time when the terminal switches based on the second path is related to the first capability. For example, if the terminal reports the first capability, both uplink transmissions of band A and band B are interrupted within time T3, or neither terminal performs (does not expect to perform) uplink transmission within time T3, and Tx2 may be used for uplink transmission within time T3. If a terminal does not report primary capability, uplink transmissions for bands A, B, and C will all be interrupted within time T3, or the terminal will not perform (expect transmission to perform) uplink transmissions within time T3.

[0121] b) The correspondence between the first route and the second scenario, wherein the interruption time or switching time when the terminal performs an uplink Tx switch based on the first route is related to the second capability, where the second scenario includes the network-side equipment scheduling transmissions of the sixth band and the seventh band.

[0122] If a predefined rule includes a correspondence between a first route and a second scenario, the second scenario is, for example, that a third band pair includes band A + band C, a fourth band pair includes band B + band C, and the network-side equipment schedules one port transmission on band B and one port transmission on band C.

[0123] In the above case, the interruption time or switching time when the terminal switches based on the first route is related to the second capability. For example, if the terminal reports the second capability, the uplink transmissions of bands A, B, and C may all be interrupted within the time period (T1) of the fourth switching cycle, or the terminal may not transmit (or not expect to transmit) within the time period T1, and Tx1 may be used for uplink transmission within the (T2-T1) time period.

[0124] If the terminal does not report a second capability, the uplink transmissions for bands A, B, and C will all be interrupted during the max(T1,T2) time, or the terminal will not expect to perform uplink transmissions within the max(T1,T2) time.

[0125] c) The correspondence between the second path and the first comparison result, wherein the first comparison result is that the target switching period is equal to or greater than the sixth switching period.

[0126] If the result of the first comparison is max(T1,T2)>=T3, the terminal performs uplink transmission based on the second path.

[0127] The time it takes for a terminal to decide whether to interrupt / switch uplink transmission depends on the terminal's primary capability report. For example, if a terminal reports primary capability, both uplink transmissions for band A and band B may be interrupted within time T3, or neither terminal may perform (expect to perform) uplink transmission within time T3, and Tx2 may be used for uplink transmission within time T3.

[0128] If the terminal does not report the first capability, uplink transmissions of bands A, B, and C will all be interrupted within T3 time, or the terminal will not perform uplink transmissions within T3 time.

[0129] d) The correspondence relationship between the first path and the second comparison result, where the second comparison result is that the target switching period is smaller than the sixth switching period.

[0130] When the second comparison result is max(T1, T2) < T3, the terminal performs uplink transmission based on the first path.

[0131] The time when the terminal determines the interruption / switching of uplink transmission depends on the report of the second capability of the terminal. For example, when the terminal reports the second capability, the uplink transmissions of band A, band B, and band C are all interrupted within T1, or the terminal does not perform transmission (does not expect transmission) within the time of T1, and Tx2 may be used for uplink transmission within the time of T2 - T1 (when T2 > T1).

[0132] When the terminal does not report the second capability, the uplink transmissions of band A, band B, and band C are all interrupted within the time of max(T1, T2).

[0133] In the above embodiment, the terminal can determine the path for performing uplink Tx switching or the time when the terminal performs uplink transmission interruption / switching based on a predefined rule, and report it to the network - side device, so that the terminal and the network - side device have a consistent understanding of the UL Tx switching behavior of the terminal, avoid uplink transmission errors, and thereby improve the uplink transmission efficiency of the terminal.

[0134] The information reporting method according to the embodiments of the present application may have an information reporting device as the execution subject. In the embodiments of the present application, taking the information reporting device executing the information reporting method as an example, the information reporting device according to the embodiments of the present application is described.
