[0035] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.

[0036] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0037] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0038] Figure 1 The following is a flow chart of a method for reporting terminal capabilities according to an embodiment of the present disclosure. In some embodiments, the following method for reporting terminal capabilities is executed by a user terminal.

[0039] In step 101, terminal capability information of a user terminal is generated.

[0040] It should be noted that the terminal capability information includes band combination information supporting uplink transmission switching, and each band combination in the band combination information includes M bands, where M is a natural number greater than 2. That is, M≥3.

[0041] In some embodiments, the frequency band combination information includes at least one of the following: uplink carrier component information supported by each frequency band in each frequency band combination, and multiple frequency band pair information supporting uplink transmission switching in each frequency band combination.

[0042] In some embodiments, in each frequency band combination, the number of frequency band pairs for uplink transmission switching is C(M,2), where C is a combination function.

[0043] That is, the user terminal reports the uplink bandwidth class for the N frequency bands.

[0044] For example, if M=3, the number of frequency band pairs in the frequency band combination is C(3,2)=3. If M=4, the number of frequency band pairs in the frequency band combination is C(4,2)=6.

[0045] In some embodiments, the plurality of frequency band pair information includes at least one of the following:

[0046] - Information about the two frequency bands included in each frequency band pair;

[0047] -Switching time information for each frequency band pair;

[0048] - Information on whether uplink transmission switching of each frequency band pair will cause downlink interruption of each frequency band in each frequency band combination.

[0049] In some embodiments, the switching time for each band pair includes at least one of a single transmitter switching time and a dual transmitter switching time.

[0050] It should be noted that the single transmitter switching time is used to indicate the time for switching a single transmitter between two frequency bands.

[0051] In some embodiments, a single transmitter switching time is used to represent single transmit to single transmit 1Tx-1Tx switching and single transmit to dual transmit 1Tx-2Tx switching.

[0052] For example, in the case of 1Tx-1Tx switching, the transmitter switches from frequency band A to frequency band B. There is one set of transmitters in both frequency band A and frequency band B, and the corresponding switching time is the single transmitter switching time.

[0053] For another example, in the case of 1Tx-2Tx switching, before the switching, the two transmitters are respectively located in band A and band B. After the switching, the two transmitters are both in band B, which is equivalent to only one transmitter being switched, and the corresponding switching time is the single transmitter switching time.

[0054] It should be noted that the dual transmitter switching time is used to indicate the time for switching the dual transmitters between two frequency bands.

[0055] For example, in the case of dual-transmit to dual-transmit 2Tx-2Tx switching, before the switching, both transmitters are located in frequency band A. After the switching, both transmitters are located in frequency band C, that is, both transmitters are switched, and the corresponding switching time is the dual-transmitter switching time.

[0056] In some embodiments, when only a single transmitter switching time is reported for a target frequency band pair, the user terminal only supports a single transmitter switching between two frequency bands of the target frequency band pair.

[0057] In some embodiments, when only the dual transmitter switching time is reported for the target frequency band pair, the user terminal supports single transmitter switching and dual transmitter switching between the two frequency bands of the target frequency band pair, where the switching time of the single transmitter switching and the dual transmitter switching is the same.

[0058] In some embodiments, when the single transmitter switching time and the dual transmitter switching time are reported for the target frequency band pair, the user terminal supports single transmitter switching and dual transmitter switching between the two frequency bands of the target frequency band pair, where the single transmitter switching is performed according to the single transmitter switching time, and the dual transmitter switching is performed according to the dual transmitter switching time.

[0059] In some embodiments, the terminal capability information further includes switching options supported by each frequency band pair, and the switching options include the following three cases: switched UL, dual UL, switched UL and dual UL.

[0060] It should be noted that switching uplink is used to indicate that the user terminal does not have the ability to perform uplink transmission in parallel in the two frequency bands of the frequency band pair. Dual uplink is used to indicate that the user terminal has the ability to perform uplink transmission in parallel in the two frequency bands of the frequency band pair. Of course, whether the user terminal performs uplink transmission in parallel depends on the scheduling of network-side equipment such as a base station.

[0061] In some embodiments, when the switching option is dual uplink, the user terminal supports uplink carrier aggregation (CA) capability of two frequency bands based on the frequency band pair.

[0062] In some embodiments, when all frequency band pairs in each frequency band combination support the same switching option, the terminal capability information includes the switching options supported by each frequency band combination.

[0063] That is to say, if in each frequency band combination, all frequency band pairs support the same switching options, in this case, there is no need to report the switching options supported by each frequency band pair, but instead report the switching options supported by the frequency band combination, thereby effectively reducing the amount of information transmission.

[0064] In some embodiments, the terminal capability information further includes capability information of whether each frequency band supporting a dual antenna connector can maintain uplink coherence (UL coherence) in the case of uplink transmission switching.

[0065] In step 102, the terminal capability information of the user terminal is sent to the network side device.

[0066] In the terminal capability reporting method provided in the above embodiment of the present disclosure, the user terminal sends its own terminal capability information to the network side device, wherein the terminal capability information includes frequency band combination information supporting uplink transmission switching, and each frequency band combination in the frequency band combination information includes M frequency bands, where M is a natural number greater than 2. Since the user terminal supports at least 3 uplink frequency bands in one frequency band combination, the user terminal can perform uplink transmission in different frequency bands or frequency band pairs at different times through dynamic transmitter switching, thereby more flexibly utilizing the transmission resources of multiple frequency bands.

[0067] Figure 2 FIG. 1 is a schematic diagram of the structure of a user terminal according to an embodiment of the present disclosure. Figure 2 As shown, the user terminal 20 includes a service processing module 21 .

[0068] The service processing module 21 is configured to generate terminal capability information of the user terminal and send the terminal capability information of the user terminal to the network side device, wherein the terminal capability information includes frequency band combination information supporting uplink transmission switching, and each frequency band combination in the frequency band combination information includes M frequency bands, where M is a natural number greater than 2.

[0069] In some embodiments, the frequency band combination information includes at least one of the following: uplink carrier component information supported by each frequency band in each frequency band combination, and multiple frequency band pair information supporting uplink transmission switching in each frequency band combination.

[0070] In some embodiments, in each frequency band combination, the number of frequency band pairs for uplink transmission switching is C(M,2), where C is a combination function.

[0071] That is, the user terminal reports the uplink bandwidth category for the N frequency bands.

[0072] For example, if M=3, the number of frequency band pairs in the frequency band combination is C(3,2)=3. If M=4, the number of frequency band pairs in the frequency band combination is C(4,2)=6.

[0073] In some embodiments, the plurality of frequency band pair information includes at least one of the following:

[0074] - Information about the two frequency bands included in each frequency band pair;

[0075] -Switching time information for each frequency band pair;

[0076] - Information on whether uplink transmission switching of each frequency band pair will cause downlink interruption of each frequency band in each frequency band combination.

[0077] In some embodiments, the switching time for each band pair includes at least one of a single transmitter switching time and a dual transmitter switching time.

[0078] It should be noted that the single transmitter switching time is used to indicate the time for switching a single transmitter between two frequency bands.

[0079] In some embodiments, a single transmitter switching time is used to represent single transmit to single transmit 1Tx-1Tx switching and single transmit to dual transmit 1Tx-2Tx switching.

[0080] For example, in the case of 1Tx-1Tx switching, the transmitter switches from frequency band A to frequency band B. There is one set of transmitters in both frequency band A and frequency band B, and the corresponding switching time is the single transmitter switching time.

[0081] For another example, in the case of 1Tx-2Tx switching, before the switching, the two transmitters are respectively located in band A and band B. After the switching, the two transmitters are both in band B, which is equivalent to only one transmitter being switched, and the corresponding switching time is the single transmitter switching time.

[0082] It should be noted that the dual transmitter switching time is used to indicate the time for switching the dual transmitters between two frequency bands.

[0083] For example, in the case of dual-transmit to dual-transmit 2Tx-2Tx switching, before the switching, both transmitters are located in frequency band A. After the switching, both transmitters are located in frequency band C, that is, both transmitters are switched, and the corresponding switching time is the dual-transmitter switching time.

[0084] In some embodiments, when only a single transmitter switching time is reported for a target frequency band pair, the user terminal only supports a single transmitter switching between two frequency bands of the target frequency band pair.

[0085] In some embodiments, when only the dual transmitter switching time is reported for the target frequency band pair, the user terminal supports single transmitter switching and dual transmitter switching between the two frequency bands of the target frequency band pair, where the switching time of the single transmitter switching and the dual transmitter switching is the same.

[0086] In some embodiments, when the single transmitter switching time and the dual transmitter switching time are reported for the target frequency band pair, the user terminal supports single transmitter switching and dual transmitter switching between the two frequency bands of the target frequency band pair, where the single transmitter switching is performed according to the single transmitter switching time, and the dual transmitter switching is performed according to the dual transmitter switching time.

[0087] In some embodiments, the terminal capability information further includes switching options supported by each frequency band pair, and the switching options include the following three cases: switched UL, dual UL, switched UL and dual UL.

[0088] It should be noted that switching uplink is used to indicate that the user terminal does not have the ability to perform uplink transmission in parallel in the two frequency bands of the frequency band pair. Dual uplink is used to indicate that the user terminal has the ability to perform uplink transmission in parallel in the two frequency bands of the frequency band pair. Of course, whether the user terminal performs uplink transmission in parallel depends on the scheduling of network-side equipment such as a base station.

[0089] In some embodiments, when the switching option is dual uplink, the user terminal supports uplink carrier aggregation capability based on two frequency bands of the frequency band pair.

[0090] In some embodiments, when all frequency band pairs in each frequency band combination support the same switching option, the terminal capability information includes the switching options supported by each frequency band combination.

[0091] That is to say, if in each frequency band combination, all frequency band pairs support the same switching options, in this case, there is no need to report the switching options supported by each frequency band pair, but instead report the switching options supported by the frequency band combination, thereby effectively reducing the amount of information transmission.

[0092] In some embodiments, the terminal capability information further includes capability information of whether each frequency band supporting the dual antenna connector can maintain uplink correlation in the case of uplink transmission switching.

[0093] In the user terminal provided by the above embodiment of the present disclosure, the service processing module sends the terminal capability information of the user terminal itself to the network side device, wherein the terminal capability information includes the frequency band combination information supporting uplink transmission switching, and each frequency band combination in the frequency band combination information includes M frequency bands, where M is a natural number greater than 2. Since the user terminal supports at least 3 uplink frequency bands in one frequency band combination, the user terminal can perform uplink transmission in different frequency bands or frequency band pairs at different times through dynamic transmitter switching, thereby more flexibly utilizing the transmission resources of multiple frequency bands.

[0101] The network side device 42 is configured to perform service scheduling for the user terminal according to the terminal capability information sent by the user terminal 41 .

[0102] In some embodiments, the network side device 42 is a base station.

[0103] By implementing the above embodiments of the present disclosure, since the user terminal supports at least three uplink frequency bands in one frequency band combination, the user terminal can perform uplink transmission on three frequency bands or more frequency bands at different times through dynamic transmitter switching. Therefore, the user terminal can still use multiple uplink frequency bands when having at most two sets of transmitters, thereby more flexibly utilizing the transmission resources of multiple frequency bands.
