[0022] In order to facilitate a clearer understanding of the technical solutions in the embodiments of the present application, some relevant background knowledge is first introduced as follows.

[0023] The UL Tx switching mechanism means that one UE transmits simultaneously using up to two Txs, one carrier supports one UL Tx (carrier 1), and the other carrier supports two UL Txs (carrier 2), carrier 1 and carrier 2 are in different bands, and two modes can be switched by switching Tx: mode 1: uplink dual-stream transmission on carrier 2, and mode 2: single-stream transmission on carrier 1 and / or carrier 2.

[0024] Depending on whether Carrier 1 and Carrier 2 support simultaneous uplink transmission, it is divided into option 1 (indicating that the upper layer parameter uplinkTxSwitchingOption-r16 set by the network is switchedUL, and Carrier 1 and Carrier 2 cannot perform uplink transmission simultaneously) and option 2 (indicating that the upper layer parameter uplinkTxSwitchingOption-r16 set by the network is dualUL, and Carrier 1 and Carrier 2 can perform uplink transmission simultaneously).

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

[0026] The network sets upper layer parameters to specify support for option 1 or option 2 for per cell group. Per serving cell is set to indicate whether the UL Tx switching cycle position is in this cell and whether this cell is carrier 1 or carrier 2.

[0027] Related technology further expands the switching scenarios for inter-band aggregation carrier (inter-CA) and supplementary uplink (SUL). It supports 2Tx-2Tx switching when both carriers support two Tx. It also supports switching between one carrier on band A and two carriers on band B (these two carriers may transmit on the same Tx). Two new RRC parameters are 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 one carrier.

[0028] When Tx 1 switches from band A to band B and Tx 2 remains in band C, in addition to following the basic terminal assumption (i.e., neither Tx can transmit on band C during the switching period), an additional terminal capability is agreed upon, i.e., Tx 2 can perform uplink transmission on band C during the switching period (additional terminal capability 1). 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 at the same time):

[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, per band pair per BC options.

[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 with reference to several embodiments and their application scenarios.

[0034] FIG. 2 is a flowchart of an information reporting method according to an embodiment of the present application. As shown in FIG. 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 is used to indicate that the terminal supports the second Tx performing uplink transmission within a first switching period, and the first switching period is a switching period corresponding to a target band pair in which the first Tx is located when performing uplink Tx switching; a second capability, which is used by the terminal to indicate that the first Tx supports uplink transmission within a first time period, the first time period being a difference between a third switching period and a second switching period, the third switching period being a switching period corresponding to a second band pair in which the second Tx is located when performing uplink switching, and the second switching period being a switching period corresponding to a first band pair in which the first Tx is located when performing uplink switching; Report the first capability based on at least one of the target band pair information, at least one band information including a first band in the target band pair, identifier information of the first band, target band list information, and BC information, where the first band is a band before the first Tx performs uplink Tx switching, or the first band is a band after the first Tx performs uplink Tx switching; 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 the present application can be applied to a scenario of uplink transmission of a terminal, where the terminal includes, but is not limited to, the types of terminal 11 listed above, and the present application is not limited thereto, and the first network side device includes, but is not limited to, the types of network side device 12 listed above, and the present application is not limited thereto.

[0036] In an embodiment of the present application, the terminal reports first information to the network side device, so that the network side device can have a consistent understanding of the UL Tx switching behavior of the terminal based on the first information, and further improve the uplink transmission efficiency of the terminal.

[0037] The first information includes at least one of a first capability and a second capability of the terminal, and the terminal is required to report the first capability and the second capability based on resources with different reporting granularity, and the resources with different reporting granularity correspond to different UL Tx switching behaviors of the terminal.

[0038] Accordingly, the granularity of the reporting capability of the terminal differs, and the signaling of the first information also differs.

[0039] For example, when the terminal reports the first capability based on the 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 a target band pair, the at least one band includes a first band, and the first band is a band before the first Tx performs uplink Tx switching, or the first band is a band after the first Tx performs uplink Tx switching, and the first band may be specified by a protocol.

[0040] 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 ENUMERATED {bandIndexUL1, bandIndexUL2}} When the terminal reports the first capability based on the identifier information of the first band pair, the signaling of the first information can be expressed as follows: Band 1::= SEQUENCE { bandIndexUL1 INTEGER(1..maxSimultaneousBands), additionalcapability1_r18} When the terminal reports the second capability based on the first band pair information and the 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 noted that the signaling of the first capability or the second capability (i.e., the signaling of the additional capability) may be the same or different signaling from the signaling of the basic capability, and the signaling of the first capability and the second capability may be the same or different signaling.

[0041] In an embodiment of the present application, the terminal reports terminal capabilities to the network side device based on resources of different reporting granularities, that is, the terminal reports first capabilities to the network side device based on at least one of target band pair information, at least one frequency band information in the target band pair, identifier information of the first band, target band list information, and BC information, and instructs the terminal to support uplink transmission by a second Tx within a first switching period; and reports second capabilities to the network side device based on the first band pair information and the second band pair information, and instructs the terminal to support uplink transmission by a first Tx within a first time period. In the above method, different reporting granularities of the terminal correspond to different UL Tx switching behaviors, so that the terminal and the network side device have a consistent understanding of the UL Tx switching behavior of the terminal, and can improve the uplink transmission efficiency of the terminal.

[0042] Optionally, different reporting granularities of the terminal correspond to different UL Tx switching behaviors, and for resources with different reporting granularities, a manner in which the terminal reports the first capability to the network side device includes at least one of the following: When the terminal reports the first capability based on each frequency band pair (per band pair per BC) in each frequency band combination, i.e., when the terminal reports the first capability based on target band pair information in the target BC, the manner in which the terminal reports the first capability includes the following Scheme 1-Scheme 2, where per BC may be an optional feature.

[0043] In method 1, when reporting the first capability based on the target band pair information, if the first Tx performs uplink Tx switching 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 period.

[0044] That is, when a target band pair of a BC reports a first capability, or the first capability corresponds to at least a target band pair, if one Tx (e.g., the first Tx, also referred to as Tx1) performs uplink Tx switching 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 band), when another Tx (e.g., the second Tx, also referred to as Tx2) is on a band other than this target band pair (e.g., a third band), Tx2 may perform uplink transmission on the third band during the Tx1 switching period (or the switching period corresponding to the target band pair), i.e., Tx2 is not affected by the Tx1 switching.

[0045] For example, if the target band pair includes band A+band B and the first capability is reported for band A+band B, when Tx1 switches from band A to band B or from band B to band A, Tx2 can perform uplink transmission on band C within the switching period of Tx1.

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

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

[0048] Reporting the first capability to the network side device based on Scheme 1 is relatively simple for the terminal to implement.

[0049] In method 2, when reporting the first capability based on the target band pair information, if the first Tx performs uplink Tx switching 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 period.

[0050] In other words, when a target band pair of a BC reports a first capability, or the first capability corresponds to at least a target band pair, when one Tx (e.g., Tx1) performs uplink Tx switching between any 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) (any one band includes band A as the band before switching or the band after switching), if Tx2 is on band B in the target band pair, Tx2 may perform uplink transmission on band B during the Tx1 switching period.

[0051] For example, if the target band pair includes band A+band B and the first capability is reported for band A+band B, Tx1 switches from band A to band C other than band B, and Tx2 can perform uplink transmission in band B within the switching time of Tx1.

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

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

[0054] According to method 2, the first capability can be reported to the network side device, and the band for uplink transmission can be determined for a certain band participating in Tx switching. However, the Tx switching time varies depending on the band pair participating in the switching, which increases the complexity of the terminal to a certain extent.

[0055] When the terminal reports the first capability based on each frequency band of each frequency band pair in each frequency band combination (per band per band pair per BC), i.e., when the terminal reports the first capability based on band information of at least one of the target band pair in the target BC, the manner in which the terminal reports the first capability includes the following Scheme 3 to Scheme 4, where per BC may be an optional feature.

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

[0057] In other words, if a band of a target band pair of a BC reports a first capability, or the first capability corresponds to at least a band, when one Tx (e.g., Tx1) switches to a band within the target band pair (e.g., this band is the first band, which may be the band before and / or after switching), and 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 switching period.

[0058] For example, if the target band pair includes band A+band B and the first capability is reported for band A in the target band pair, when Tx1 switches between band A and band B (including when Tx1 switches from band A to band B or when 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 noted that the difference between Scheme 3 and Scheme 1 is that in Scheme 3, at least one band in the target band pair includes a first band, and the first band is the band before uplink Tx switching or the first band is the band after uplink Tx switching. The first band may be determined by any one of protocol specification, instruction in UE capability report, and base station configuration.

[0060] In method 4, when the first capability is reported based on the target band pair information and the first band information in the target band pair, if the first Tx performs uplink Tx switching 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 in the second band in the target band pair within the first switching period.

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

[0062] For example, if the target band pair includes band A+band B and the first capability is reported for band A in the target band pair, when Tx1 switches between band A and band C (e.g., including 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] It should be noted that the difference between Scheme 4 and Scheme 2 is that Scheme 4 may determine that the first band is a band in the target band pair by any one of the following methods: protocol specification, instruction in the terminal capability report, and base station configuration.

[0064] When the terminal reports the first capability based on each frequency band (per band per BC) in each frequency band combination, i.e., when the terminal reports the first capability based on the identifier information of the first band in the target BC, the manner in which the terminal reports the first capability includes the following manner 5, where per BC may be an optional feature.

[0065] In method 5, when reporting the first capability based on identifier information of the first band, when the first Tx performs uplink Tx switching in the first band, the terminal uses the second Tx to perform uplink transmission in a third band within the first switching period, and the third band is different from the band in which the first Tx is located when performing uplink Tx switching.

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

[0067] Optionally, the target band is any band that can perform Tx switching with the first band.

[0068] Alternatively, the target band is a specific band that can perform Tx switching with the first band, and the specific band may be defined by a protocol, for example, a band where a PUCCH is located.

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

[0070] When the terminal reports the first capability based on each frequency band list (per band list per BC) in each frequency band combination, i.e., when the terminal reports the first capability based on target band list information in the target BC, the manner in which the terminal reports the first capability includes the following manner 6, in which 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 an optional feature.

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

[0072] That is, if a band list of a BC reports a first capability, when one Tx (e.g., Tx1) switches in this target band list (including Tx1 switching from another band to a band in this target band list, or switching from a band in this target band list to another band), and another Tx (e.g., Tx2) is on another band (e.g., a third band) other than the above two bands, Tx2 may perform uplink transmission on the third band during the Tx1 switching period.

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

[0074] That is, when Tx1 switches from one band in BC to another band, 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, i.e., the uplink transmission on the third band is not affected by other Tx switching.

[0075] When the terminal reports the first capability on a per-UE basis, the manner in which the terminal reports the first capability includes the following manner 8: In method 8, when the first Tx performs uplink Tx switching in any one of the bands corresponding to the terminal, the terminal uses the second Tx to perform uplink transmission in a third band within the first switching period, and the third band is different from the band in which the first Tx is located when performing uplink Tx switching.

[0076] The terminal capability reporting granularity is based on per BC or per UE, which has a larger granularity but may cause significant implementation complexity increase.

[0077] Optionally, the third band comprises: a) a band other than the target band pair; b) a specific band, c) a band defined by the protocol; d) Includes any one of the target band pair and the bound band 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 in 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 period 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 when 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 period of (Tswitch_2 - Tswitch_1).

[0086] It should be noted that the terminal capability 0 refers to that both of the two Tx's in the second band pair switch according to a longer time period (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] That is, if at least one of the two band pairs does not have the second capability, the terminal does not allow Tx1 to be used for uplink transmission within the time period (Tswitch_2-Tswitch_1).

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

[0090] Alternatively, the terminal performing uplink transmission using the first Tx during the first time period may be specifically achieved by the following steps: When a target condition is satisfied, the terminal performs uplink transmission using the first Tx within a first time period; The target condition is: a) the third switching period and the second switching period at least partially overlap 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.

[0091] In the above embodiment, the terminal reports the second capability based on different reporting granularities, so that the terminal and the network side device have a consistent understanding of the UL Tx switching behavior of the terminal, avoiding uplink transmission errors and thereby improving the uplink transmission efficiency of the terminal.

[0092] Alternatively, when the first Tx and the 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 band and the seventh band, and the fourth band pair includes the sixth band and the seventh band, that is, when the Tx2 and Tx1 of the terminal switch from (band A+band C) uplink to (band B+band C), the terminal determines at least one of the following based on a targeting scheme, including a path for the terminal to perform uplink Tx switching or a time for the terminal to interrupt / switch uplink transmission, where: a) The terminal performs uplink Tx switching based on a first route, and the first route is 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 contains (band A + band C) and the fourth band pair contains (band B + band C), the first path is used to instruct Tx1 to switch from band A to band C and Tx2 to switch from band C to band B.

[0094] b) The terminal performs uplink Tx switching based on a second path, wherein the second path is 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 in 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 should switch from band A to band B and Tx2 should remain on band C.

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

[0097] For example, if the third band pair includes a fifth band (band A) and a seventh band (band C), and the fourth band pair includes a sixth band (band B) and a seventh band (band C), uplink transmissions of band A, band B, and band C will all be suspended during the target switching period, or the terminal will not expect to perform uplink transmissions during the target switching period.

[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, and specifically, the target switching period may be expressed as max(T1, T2).

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

[0100] For example, if the third band pair includes a fifth band (band A) and a seventh band (band C), and the fourth band pair includes a sixth band (band B) and a seventh band (band C), uplink transmissions of band A, band B, and band C may all be suspended during the time period (T1) of the fourth switching period, or none of the terminals may transmit (or expect no transmission) during the time period T1, and Tx2 may be used for uplink transmission during the second time period.

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

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

[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), and uplink transmissions of band A, band B, and band C are all suspended during the sixth switching period, or none of the terminals performs (expects) uplink transmission during the sixth switching period.

[0104] Here, the sixth switching period is a switching time period during 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) The uplink transmission of the fifth band and the sixth band is both interrupted within the sixth switching period, or the terminal does not perform uplink transmission within the sixth switching period, or the terminal performs uplink transmission within the sixth switching period.

[0106] 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), and the uplink transmissions of band A and band B are both suspended during the sixth switching period (T3), or neither terminal performs uplink transmission (is expecting transmission) during the period T3, and Tx2 may be used for uplink transmission during the period 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 targeting scheme, 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.

[0108] Optionally, the targeting method comprises: a) the implementation method of the terminal; b) Terminal reporting method; c) UE capability reporting method; d) predefined rules.

[0109] Optionally, when the target mode includes the UE capability reporting mode and the terminal reports the first capability to the network side device, determining that the terminal performs uplink Tx switching based on the second route; For example, when the terminal reports a first capability to the network side device, the terminal determines, based on the UE capability reporting method, to perform uplink Tx switching based on the second path, i.e., 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.

[0110] In response, band A and band B both suspend transmission according to max(T1, T2, T3), and band C transmits according to only the Tx2 terminal.

[0111] Or, If the target mode includes the UE capability reporting mode and the terminal reports the second capability to the network side device, the terminal determines to perform uplink Tx switching based on the first route.

[0112] For example, when the terminal reports the second capability to the network side device, the terminal determines, based on the UE capability reporting method, to perform uplink Tx switching 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 Tx1 to switch from band A to band C and Tx2 to switch from band C to band B.

[0113] In response, band A and band B both suspend transmission according to max(T1, T2, T3), and band C transmits according to only the Tx1 terminal.

[0114] It should be noted that if the targeting scheme includes the UE capability reporting scheme and the terminal has not reported the first capability or the second capability to the network side device, the terminal may determine the interruption / switching time of uplink transmission according to the following scheme:

[0115] a) 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), uplink transmissions of band A, band B, and band C will all be interrupted within a time period max(T1, T2).

[0116] b) The uplink transmissions of band A, band B, and band C are all suspended within time T3, or the terminal does not perform uplink transmission within the time of the sixth switching period.

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

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

[0119] When the predefined rule includes a correspondence between the second route and the first scenario, the first scenario is, for example, a case where the third band pair includes band A+band C, the fourth band pair includes band B+band C, Tx2 and Tx1 of the terminal switch from the uplink Tx of the third band pair to the fourth band pair, the network side equipment schedules 1-port transmission of band B, oneT is set in the RRC parameter, 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 route is related to the first capability. For example, when the terminal reports the first capability, uplink transmissions of band A and band B may both be interrupted within a time T3, or the terminal may not perform (or expect to perform) uplink transmission within a time T3, and Tx2 may be used for uplink transmission within a time T3. If the terminal does not report the first capability, uplink transmissions of band A, band B, and band C are all suspended within time T3, or the terminal does not perform (or does not expect to perform) uplink transmissions within time T3.

[0121] b) A correspondence relationship between the first route and a second scenario, wherein the interruption time or switching time when the terminal performs uplink Tx switching based on the first route is related to the second capability, and wherein the second scenario includes a network side device scheduling transmission of the sixth band and transmission of the seventh band.

[0122] When the predefined rule includes a correspondence between the first route and the second scenario, the second scenario is, for example, a case where the third band pair includes band A+band C, the fourth band pair includes band B+band C, and the network side device schedules one port transmission of band B and one port transmission of 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, when the terminal reports the second capability, uplink transmissions of bands A, B, and C may all be interrupted during time period (T1) of the fourth switching period, or none of the terminals may transmit (or expect to transmit) during time period T1, and Tx1 may be used for uplink transmission during time period (T2-T1).

[0124] If the terminal does not report the second capability, uplink transmissions on band A, band B, and band C are all suspended for a time max(T1, T2), or the terminal does not expect to perform uplink transmissions within the time max(T1, T2).

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

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

[0127] The time when the terminal decides to suspend / switch uplink transmission depends on the terminal's first capability report. For example, when the terminal reports the first capability, uplink transmissions of band A and band B may both be suspended within time T3, or the terminal may not perform (or 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, the uplink transmissions of band A, band B, and band C are all suspended within time T3, or the terminal does not perform uplink transmission within time T3.

[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 transmit within the time of T1 (does not expect transmission), 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 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.
