[0003] In order to enhance the uplink transmission capability, the communication industry proposes an uplink switching technology, which uses the uplink selection transmission function of the terminal to enhance the uplink coverage and rate effect. For example, in the area outside the NR (New Radio) TDD (Time Division Duplexing) uplink coverage of the terminal, the terminal transmits data in the manner of FDD (Frequency Division Duplexing) and TDD each 1TX (Transmit Channel). In the uplink coverage area of FDD and TDD, the uplink time slot of TDD is switched to the TDD carrier to use 2Tx, that is, the UL (UpLink) MIMO (multiple-in multiple-out) mode is used to transmit data, thereby improving the throughput of the uplink.

[0030] Exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0031] Some concepts and / or terms involved in the schemes provided in the embodiments of the present application will be explained below.

[0032] Frequency Division Duplex (FDD), also known as full duplex, refers to the uplink (mobile station to base station) and downlink (base station to mobile station) using two separate frequencies (with certain frequency interval requirements) to work, that is, two independent channels are needed for operation. One channel is used to transmit information downward, and the other channel is used to transmit information upward. There is a protection frequency band between the two channels to prevent mutual interference between adjacent transmitters and receivers.

[0033] Time Division Duplex (TDD), also known as half duplex, in a mobile communication system in TDD mode, because the transmitter and receiver do not operate at the same time, they cannot interfere with each other, so the receiving and transmitting are in the same frequency channel (i.e. carrier) at different time slots, and the receiving and transmitting channels are separated by time.

[0034] Currently, 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) proposes two uplink enhancement technologies SUL (supplementary uplink) and UL CA (carrier aggregation), the essence of which is to enhance the uplink through TDD / FDD, high frequency / low frequency complementary. Referring to Figure 1 SUL can only perform uplink transmission on one carrier at the same time, mainly used to improve the coverage of the cell edge, and cannot improve the capacity of the near point; UL CA uplink two carriers concurrent, limited to the near point to improve the uplink capacity.

[0035] The above traditional SUL and UL CA techniques have certain deficiencies, in recent years, the communication industry proposes a super uplink technology (uplink switching), through the uplink selection transmission function of the terminal, further enhances the uplink coverage and rate effect (such as sending uplink data through FDD carrier in TDD downlink time slot, using TDD carrier to send uplink data in TDD uplink time slot), signal transmission mode reference Figure 2 , Figure 2 The TDD2TX and FDD1TX time division transmission time slot diagram is shown in the figure, wherein U represents uplink, D represents downlink, and S represents a special frame for separating U and D.

[0036] Taking UL CA FDD+TDD as an example, the UE (terminal) is located at a far point of the cell, and the uplink data is transmitted through the FDD (low frequency) carrier preferentially, so as to ensure that the network has a larger coverage range; the UE is located at a near point of the cell, and the uplink time slot of the TDD switches the UE to the NR TDD carrier for uplink scheduling, at this time, the UE can use UL MIMO to transmit data on the NR carrier, since the NR has a larger bandwidth and higher spectrum efficiency than the LTE (Long Term Evolution), the uplink transmission rate can be improved, and in the downlink time slot and the special time slot of the NR TDD carrier, the LTE FDD can be used for uplink data transmission; but when the UE is at the middle point, that is, in the middle zone between the far point and the near point, the throughput and the uplink coverage range need to be considered, and the current UE is a 2TX terminal, which can only adopt FDD 1TX+TDD 1TX to transmit uplink transmission.

[0037] Referring to Figure 3 The embodiment of the present application discloses a signal transmission control method, applied to an electronic device, the electronic device supports carrier aggregation, the electronic device includes a plurality of power amplifiers, the plurality of power amplifiers are powered by three power supplies, the number of power amplifiers connected by each power supply is greater than or equal to one, and the method comprises the following steps:

[0038] Step 101, acquiring the uplink signal strength value of the terminal.

[0039] In the embodiment of the present application, referring to Figure 4RFIC stands for Radio Frequency Transceiver. LBPA, MHB PA, NR MMPA, N78PA0, and N78 PA1 represent multiple power amplifiers with different transmit power levels. APT / ET represents the power supply. Multiple power amplifiers are powered by three power supplies, each power supply connecting to at least one power amplifier. The RF transceiver is used to output LTE and / or NR signals, and to perform signal processing on LTE and / or NR signals received by one or more antennas. Signal processing includes, but is not limited to, frequency conversion, demodulation, and analog-to-digital conversion. The uplink signal transmitted by the RF transceiver is amplified by the power amplifiers and then transmitted by the antenna. An antenna is a converter used to convert RF signals into electromagnetic waves of corresponding wavelengths and radiate them into the air, and / or to receive electromagnetic waves and convert them into corresponding RF signals. It is understood that the same antenna can both transmit and receive RF signals. RF signals can include LTE signals and NR signals, etc. The input of the power amplifier is connected to the RF transceiver, and the output is connected to the antenna. The power amplifier is also connected to a power supply. When the terminal transmits uplink signals in a preset frequency band, the power supply provides power to the power amplifier connected to the preset frequency band, enabling the transmission of the uplink signal. By obtaining the uplink signal strength value of the terminal, the distance between the terminal and the base station can be determined, thereby determining how the terminal should perform uplink transmission.

[0040] Optionally, step 101 specifically includes:

[0041] Sub-step 1011: Obtain a first signal and a second signal. The first signal is used to characterize the signal value transmitted by the base station received by the terminal, and the second signal is used to characterize the signal value sent by the terminal to the base station after receiving the first signal.

[0042] Sub-step 1012: Determine the uplink signal strength value of the terminal based on the difference between the first signal and the second signal.

[0043] In this embodiment, the first signal can be SRS (Signal Receiving Power), and the second signal can be RSRP (Reference Signal Receiving Power). By measuring SRS and RSRP, the uplink coverage in TDD is detected. In wireless communication, SRS is used to estimate uplink channel frequency domain information for frequency-selective scheduling; RSRP is used to estimate downlink channel for downlink beamforming. That is, the uplink signal strength of the terminal can be determined by the difference between the SRS signal value transmitted from the base station to the terminal and the RSRP signal value sent back to the base station by the terminal after receiving the SRS signal value. Based on the uplink signal strength value, it can be determined how the terminal should transmit uplink signals.

[0044] If the uplink signal strength value is greater than the first threshold value and less than the second threshold value, it is determined that the terminal is located at a midpoint of the cell, and the three power supplies are controlled to supply power to the connected power amplifiers simultaneously to realize simultaneous uplink transmission of the three transmission channels.

[0045] In the embodiments of the present application, the reference Figure 5 Figure 5 is a signal coverage map, R1 represents the coverage of the TDD signal, and R2 represents the coverage of the FDD signal. When the terminal is located within R1, it indicates that the terminal is located at a near point of the base station. When the terminal is located outside R1, it indicates that the terminal is located at a far point of the base station. When the terminal is located within the range of R1±δ, it indicates that the terminal is located in the middle zone of the TDD and FDD coverage. The first threshold value can be the signal strength value when the terminal is located at R1+δ, and the second threshold value can be the signal strength value when the terminal is located at R1-δ. When it is determined that the uplink signal strength value of the terminal is greater than the first threshold value and less than the second threshold value by acquiring the uplink signal strength value of the terminal, it is determined that the terminal is located in the middle zone. At this time, in order to improve the uplink signal transmission power of the terminal in the middle zone, TDD 2TX transmission can be activated, so that the three power supplies work simultaneously to realize simultaneous operation of the three transmission channels, that is, FDD 1TX+TDD 2TX simultaneously transmit uplink transmission, so as to improve the uplink transmission power of the terminal when the terminal is located in the middle zone.

[0046] Optionally, the electronic device includes a low-frequency port, a first intermediate-frequency port, a second intermediate-frequency port, a first high-frequency port, a second high-frequency port, a first ultrahigh-frequency port, and a second ultrahigh-frequency port. Step 102 specifically includes:

[0047] Sub-step 1021: Determine whether there is a harmonic or intermodulation interference signal in the uplink signal.

[0048] In the embodiments of the present application, the intermodulation interference is generated by a nonlinear circuit in the transmission channel. When two or more signals of different frequencies are input into the nonlinear circuit, due to the action of the nonlinear device, many harmonic and combined frequency components will be generated. Among them, the combined frequency components close to the required signal frequency will successfully pass through the receiver to form interference. This interference is called intermodulation interference. After activating TDD 2TX transmission, it is determined whether there is a harmonic or intermodulation interference signal in the uplink signal to determine whether NR and LTE are simultaneously transmitted.

[0049] ​In sub-step 1022, if there are harmonic or intermodulation interference signals, a third target port is determined from the low-frequency port, the first intermediate frequency port, the second intermediate frequency port, the first high-frequency port, and the second high-frequency port. The third target port, the first ultra-high frequency port, and the second ultra-high frequency port are used for uplink transmission in time-division transmission, and the power supply is controlled to supply power to the power amplifiers corresponding to the third target port, the first ultra-high frequency port, and the second ultra-high frequency port.

[0050] In the embodiments of this application, reference is made to Figure 4 The system includes multiple power amplifiers, including: a first power amplifier LBPA, a second power amplifier MHB PA, a third power amplifier NR MMPA, a fourth power amplifier N78 PA0, and a fifth power amplifier N78 PA1; and an RF transceiver including: a low-frequency port LB TX, a first intermediate frequency port MB TX1, a second intermediate frequency port MB TX2, a first high-frequency port HB TX1, a second high-frequency port HB TX2, a first ultra-high frequency port UHB TX1, and a second ultra-high frequency port UHB TX2. The low-frequency port LB TX is connected to the first power amplifier LBPA; the first intermediate frequency port MB TX1 and the first high-frequency port HB TX1 are respectively connected to the second power amplifier MHB PA; the second intermediate frequency port MB TX2 and the second high-frequency port HB TX2 are respectively connected to the third power amplifier NR MMPA; the first ultra-high frequency port UHB TX1 is connected to the fourth power amplifier N78 PA0; and the second ultra-high frequency port UHB TX2 is connected to the fifth power amplifier N78 PA1.

[0051] The first power amplifier LBPA amplifies the low-frequency signal transmitted by the low-frequency port LB TX. The second power amplifier MHB PA amplifies the intermediate frequency (IF) or high-frequency (HF) signals transmitted by the first intermediate frequency (IF) port MB TX1 and the first high-frequency (HF) port HB TX1. The third power amplifier NR MMPA amplifies the IF and HF signals transmitted by the second IF port MB TX2 and the second HF port HB TX2. The fourth power amplifier N78 PA0 amplifies the first ultra-high frequency (UHF) signal transmitted by the first ultra-high frequency (UHF) port UHB TX1. The fifth power amplifier N78 PA1 amplifies the second UHF signal transmitted by the second UHF port UHB TX2. The low-frequency port of the RF transceiver can be a port that incorporates multiple low-frequency sub-bands, the IF port can be a port that incorporates multiple IF sub-bands, the HF port can be a port that incorporates multiple HF sub-bands, and the UHF port can be a port that incorporates multiple UHF sub-bands. When the terminal transmits a signal, it transmits an uplink signal from the corresponding port according to the frequency band supported by the terminal. After being amplified by the power amplifier corresponding to that frequency band, the signal is transmitted by the antenna.

[0052] Referring to Figure 4 , if there is no harmonic or intermodulation interference signal, a fourth target port is determined from the low-frequency port LB TX, the first intermediate-frequency port MB TX1, and the first high-frequency port HB TX1, and the fourth target port, the first ultra-high-frequency port UHBTX1, and the second ultra-high-frequency port UHB TX2 simultaneously perform uplink transmission, and the power supply simultaneously supplies power to the power amplifiers corresponding to the fourth target port, the first ultra-high-frequency port, and the second ultra-high-frequency port. Figure 2 Referring to

[0053] Substep 1023, if there is no harmonic or intermodulation interference signal, a fourth target port is determined from the low-frequency port, the first intermediate-frequency port, and the first high-frequency port, and the fourth target port, the first ultra-high-frequency port, and the second ultra-high-frequency port simultaneously perform uplink transmission, and the power supply simultaneously supplies power to the power amplifiers corresponding to the fourth target port, the first ultra-high-frequency port, and the second ultra-high-frequency port.

[0054] In the embodiment of the present application, referring to Figure 4 , if there is no harmonic or intermodulation interference signal, FDD 1TX and TDD 2TX are used for simultaneous transmission, that is, 3TX simultaneously sends uplink transmission, a fourth target port can be determined from the low-frequency port LB TX, the first intermediate-frequency port MB TX1, and the first high-frequency port HB TX1, the fourth target port is used to realize FDD 1TX transmission, and the first ultra-high-frequency port UHBTX1 and the second ultra-high-frequency port UHB TX2 are used to realize TDD 2TX transmission, which can not only ensure stable uplink coverage, but also meet the uplink rate requirement (especially in the middle position, without back to FDD 1TX and TDD 1TX transmission), and referring to Figure 6 the signal time slot diagram, the bold U in the figure indicates the time slot of uplink transmission.

[0055] Optionally, the three power supplies are a first power supply, a second power supply, and a third power supply, the first power supply is connected to the first power amplifier and the second power amplifier, the second power supply is connected to the third power amplifier and the fourth power amplifier, and the third power supply is connected to the fifth power amplifier, and the substep 1023 specifically includes:

[0056] Substep 10231, control the first power supply to supply power to the first power amplifier or the second power amplifier, the second power supply to supply power to the fourth power amplifier, and the third power supply to supply power to the fifth power amplifier.

[0057] In the embodiment of the present application, referring toFigure 4 , the first power supply APT / ET0 is used for supplying power to the first power amplifier LB PA and the second power amplifier MHB PA, the second power supply APT / ET1 is used for supplying power to the third power amplifier NR MMPA and the fourth power amplifier N78 PA0, and the third power supply APT / ET2 is used for supplying power to the fifth power amplifier N78 PA1, each power supply supplies power to only one power amplifier at the same time, since the first power amplifier LB PA and the second power amplifier MHB PA do not work at the same time, the first power amplifier LB PA and the second power amplifier MHB PA can be supplied by the first power supply APT / ET0, and the third power amplifier NR MMPA and the fourth power amplifier N78 PA0 do not work at the same time, so the third power amplifier NR MMPA and the fourth power amplifier N78 PA0 can be supplied by the second power supply APT / ET1, so that different power supplies can be scheduled to supply power to the power amplifier according to different positions of the terminal, and signal transmission of the terminal in different uplink transmission scenarios is realized,

[0058] Further, the first power supply, the second power supply and the third power supply can be an average power tracking mode (APT) power supply or an envelope tracking mode (ET) power supply. When the power supply is an average power tracking mode power supply, the power supply is connected with the radio frequency transceiver, and the power supply is controlled by the radio frequency transceiver to supply power; when the power supply is an envelope tracking mode power supply, the power supply is connected with the integrated power management circuit, and the power supply is controlled by the integrated power management circuit to supply power. The envelope tracking (ET) mode power supply is a technology that establishes a connection between the working voltage of the power amplifier and the input radio frequency signal to make them follow each other in real time, thereby improving the working efficiency of the power amplifier. The average power tracking (APT) mode power supply is a technology that automatically adjusts the working voltage of the power amplifier according to the pre-output power of the power amplifier and the parameters of the power amplifier.

[0059] Reference Figure 4 By setting three power supplies and judging the position of the terminal, the uplink throughput in the middle zone position area is maximized, thereby improving user experience and latency; the uplink transmission mode is flexible and variable for different application scenarios; the circuit reuse platform chip SOC sleeve module has basically no additional hardware cost, such as Figure 7 、 8 BUCK module, which is not used in most current projects, and does not need to be purchased separately, and can be used with the power switch to reduce the cost.

[0060] Reference Figure 4When in the intermediate zone, in order to realize 3TX, the first power supply can be controlled to supply power to the first power amplifier or the second power amplifier, the second power supply supplies power to the fourth power amplifier, and the third power supply supplies power to the fifth power amplifier, so that the three power supplies work at the same time to supply power to the corresponding power amplifiers, realizing three transmission channels for uplink transmission at the same time.

[0061] Optionally, the electronic device comprises a switch, the three power supplies are a first power supply, a second power supply and a third power supply, the first power supply and the second power supply are connected to two static terminals of the switch, one dynamic terminal of the switch is connected to the first power amplifier and the second power amplifier, and the other dynamic terminal of the switch is connected to the fifth power amplifier, and the sub-step 1023 specifically comprises.

[0062] The sub-step 10232 comprises controlling the first power supply to communicate with the first power amplifier or the second power amplifier through the switch to supply power to the first power amplifier or the second power amplifier.

[0063] The sub-step 10233 comprises controlling the second power supply to communicate with the fifth power amplifier through the switch to supply power to the fifth power amplifier, and the third power supply supplies power to the fourth power amplifier.

[0064] Reference Figure 7 The radio frequency circuit further comprises a switch, which can be a DPDT (double pole double throw switch), the first power supply BUCK APT can be a power supply obtained by pulling out one power supply from an original PMIC (integrated power management circuit) as an APT power supply, and the second power supply APT / ET0 and the third power supply APT / ET1 can be one of an APT power supply or an ET power supply. At this time, compared with using three ET power supplies for power supply, one ET power supply is reduced, and the occupation of the PCB (Printed Circuit Board) layout space is reduced. Through the switch, the power supply change of the power amplifier in different uplink transmission scenarios is realized, the performance is increased, and the cost and the PCB layout are basically not under pressure.

[0065] Further, taking CA_n1-n78 as an example, the n1 frequency band is amplified by the MHB PA. When the terminal is at a cell far point, because the n78 propagation loss is large, the uplink coverage capability is weak, and therefore only n1 1TX is used for uplink transmission, at this time the APT / ET0 supplies power to the MHB PA (the APT / ET0 performance is superior to the BUCK APT, and therefore power supply is preferentially performed by the APT / ET0); when the terminal is at a cell intermediate zone, the uplink coverage capability and throughput are taken into account, n78 2TX+n1 1TX is concurrently used, at this time the MHB PA power supply is switched to the BUCK APT, the APT / ET1 supplies power to the N78 PA0, and the APT / ET0 supplies power to the N78 PA1, that is, 2TX or 3TX is used to transmit uplink data in the n78 downlink time slot and uplink time slot; when the terminal is at a cell near point, the uplink coverage area of n1 and n78 is common, and the terminal can select n1 1TX and n78 2TX time division to perform uplink transmission. In the n78 downlink time slot, the APT / ET0 supplies power to the MHB PA; in the n78 uplink time slot, the APT / ET0 supplies power to the N78 PA1, and the APT / ET1 supplies power to the N78 PA0.

[0066] In the embodiment of the present application, reference is made to Figure 7 When at the intermediate zone, in order to realize 3TX, the first power supply BUCK APT can be controlled to communicate with the first power amplifier LB PA or the second power amplifier MHB PA through the switching switch DPDT to supply power to the first power amplifier LB PA or the second power amplifier MHB PA, the second power supply APT / ET0 communicates with the fifth power amplifier N78 PA1 through the switching switch to supply power to the fifth power amplifier N78 PA1, and the third power supply APT / ET1 supplies power to the fourth power amplifier N78 PA0. 3-way transmission channels are realized to work simultaneously.

[0067] Optionally, the electronic device includes a low-frequency port, a first intermediate-frequency port, a second intermediate-frequency port, a first high-frequency port, and a second high-frequency port, and the method further includes:

[0068] In step 103, if the uplink signal strength value is less than the first threshold value, it is determined that the terminal is at a cell far point position.

[0069] Reference is made to Figure 5 In the embodiment of the present application, if the uplink signal strength value is less than the first threshold value, it is determined that the terminal is at a far point, that is, in a region outside (R1+δ).

[0070] In step 104, one of the low frequency port, the first intermediate frequency port, the second intermediate frequency port, the first high frequency port, and the second high frequency port is determined as a first target port for uplink transmission according to the uplink signal strength value, and a power supply is controlled to supply power to a power amplifier corresponding to the first target port.

[0071] In the embodiments of the present application, when the terminal is at a far point of a cell, uplink uses FDD 1TX transmission, and one of the first intermediate frequency port, the second intermediate frequency port, the first high frequency port, and the second high frequency port can be determined as a first target port according to the terminal transmission frequency, and the first target port is used to implement FDD 1TX transmission. Referring to Figure 9 Figure 9 is a signal time slot diagram for FDD 1TX transmission. In the figure, the bold U represents uplink transmission, and it can be seen that in each time slot of uplink, FDD 1TX is used for uplink transmission to ensure signal coverage.

[0072] Optionally, the electronic device includes a low frequency port, a first intermediate frequency port, a second intermediate frequency port, a first high frequency port, a second high frequency port, a first ultrahigh frequency port, and a second ultrahigh frequency port, and the method further includes:

[0073] In step 105, if the uplink signal strength value is greater than a first threshold value, it is determined that the terminal is at a near midpoint of a cell, and whether the terminal supports super uplink is detected.

[0074] In the embodiments of the present application, whether the terminal supports super uplink is determined to determine whether the terminal can perform uplink transmission using super uplink technology.

[0075] In step 106, if the terminal supports super uplink, it is determined whether the uplink signal strength value is greater than a second threshold value.

[0076] In the embodiments of the present application, it is determined whether the signal strength value is greater than the second threshold value by continuing to monitor RSP and RSRP, i.e., the signal strength value at R1-δ.

[0077] In step 107, if the uplink signal strength value is greater than the second threshold value, it is determined that the terminal is at a near point of a cell, one of the low frequency port, the first intermediate frequency port, the second intermediate frequency port, the first high frequency port, and the second high frequency port is determined as a second target port, and the second target port, the first ultrahigh frequency port, and the second ultrahigh frequency port are used for uplink transmission using time division transmission, and a power supply is controlled to supply power to power amplifiers corresponding to the second target port, the first ultrahigh frequency port, and the second ultrahigh frequency port.

[0078] ​In the embodiment of the present application, if the uplink signal strength value is greater than the second threshold value, it indicates that the terminal is in a region within (R1-δ), at this time the signal of the terminal is better, and the TDD uplink coverage can meet the communication needs of the terminal, therefore, at this time, FDD 1TX+TDD 2TX time division transmission can be used, according to the transmission frequency of the terminal, a second target port is determined from the low frequency port, the first intermediate frequency port, the second intermediate frequency port, the first high frequency port and the second high frequency port, the second target port is used to realize FDD 1TX transmission, and the first ultrahigh frequency port and the second ultrahigh frequency port are used to realize TDD 2TX transmission.

[0079] It should be noted that the plurality of antennas in the present application includes: a first antenna, a second antenna, a third antenna, a fourth antenna and a fifth antenna; the first antenna is connected with the first power amplifier, the second antenna is connected with the second power amplifier, the third antenna is connected with the third power amplifier, the fourth antenna is connected with the fourth power amplifier, and the fifth antenna is connected with the fifth power amplifier.

[0080] Referring to Figure 4 Figure 7 An antenna is a kind of transducer for converting radio frequency signals into electromagnetic waves of corresponding wavelengths and radiating them into the air, and for receiving electromagnetic waves and converting them into corresponding radio frequency signals. The same antenna can both transmit radio frequency signals and receive radio frequency signals. Radio frequency signals can include LTE signals and NR signals, etc. After the uplink signal is amplified by the power amplifier, it is radiated into the air through the antenna for uplink transmission.

[0081] Further, the present application is based on PMIC and ET to realize simultaneous power supply for multiple power supplies, combined with network algorithm scheduling. It can be extended to ENDC combined power supply, such as LB+MHB combination. In the case of antenna switching or reverse connection caused by power supply problems, different power supply networks can be used to improve the performance degradation or cost increase caused by the above complex scenarios.

[0082] Referring to Figure 10 Figure 10 ​​As another signal transmission control method flow chart, wherein, step S01 terminal by searching for a random access to the main node and stay broadcast signal; network node of the main node provides a control plane connection with the core network, the terminal enters the UE Capability process, that is, reporting UE capability, UE Capability includes: UE Capability request and UE Capability report. When the base station needs the UE to report the UE capability, the base station will issue the UE CapabilityEnquiry instruction to the UE. When the UE receives the UE CapabilityEnquiry instruction, the UE reports the UE capability UE CapabilityInformation according to the instruction. The base station can only make correct scheduling for the UE after knowing the UE capability. If the UE supports a certain function, the base station can configure the function for the UE; if the UE does not support a certain function, the base station cannot configure the function for the UE.

[0083] Step S02, the terminal determines to support carrier aggregation by reporting, if not supporting, the secondary node is not configured, and only the main node does business.

[0084] If the terminal supports carrier aggregation, step S03 is entered, and the secondary node is added to the terminal. The secondary node can be activated based on measurement or activated by blind addition.

[0085] Further, after adding the secondary node, step S04 is entered, and the uplink signal strength value of the terminal is determined by SRS and RSRP. If the uplink signal strength value is less than the first threshold value, it is determined that the terminal is at a far point, and FDD 1TX transmission is used for uplink at this time.

[0086] If the uplink signal strength value is greater than the first threshold value, step S05 is entered, and it is judged whether the terminal supports super uplink to determine whether the terminal can perform uplink transmission in super uplink technology. If super uplink transmission is not supported, FDD 1TX+TDD 1TX transmission is used for uplink.

[0087] If super uplink is supported, step S06 is entered, and super uplink is activated.

[0088] Step S07, the signal strength value is determined by continuing to monitor RSP and RSRP whether it is greater than the second threshold value, that is, the signal strength value at R1-δ. If the uplink signal strength value is greater than the second threshold value, it indicates that the terminal is in the area within (R1-δ), at this time the signal of the terminal is good, and the TDD uplink coverage can meet the communication demand of the terminal, therefore, at this time FDD 1TX+TDD 2TX time division transmission can be used. After the uplink transmission is completed, step S11 is entered, and the next round of transmission mode selection is prepared.

[0089] When the uplink signal strength value is greater than the first threshold value and less than the second threshold value, it indicates that the terminal is currently in the middle zone of FDD and TDD uplink coverage, at this time, step S08 is entered, and TDD2TX transmission is activated.

[0090] S09, it is judged whether there is an interference signal, if not, step S10 is entered, and three transmission channels simultaneously perform uplink transmission, that is, FDD1TX+TDD2TX simultaneously transmits, so as to improve the uplink transmission power of the terminal when the terminal is in the middle zone. If there is interference, FDD1TX+TDD2TX time division transmission is adopted.
