[0002] The radio frequency system of a terminal may include power amplifiers (PAs) for low frequency bands (LB), middle frequency bands (MB), high frequency bands (HB), and ultra-high frequency bands (UHB). Independent PAs are used for different frequency bands. Currently, due to cost limitations, the number of PAs included in a terminal is limited, resulting in the lack of concurrent capabilities for some frequency bands. For example, a terminal generally includes one PA for each of LB, MB, HB, and UHB. In this case, it is impossible to support the uplink concurrency of UHB and HB, the communication scenario is limited, and the user experience is poor. Summary of the Invention

For example, B3 is the Frequency Division Duplexing (FDD) band with an LTE band number of 3: 1710 megahertz (MHz) to 1785 MHz for the uplink and 1805 MHz to 1880 MHz for the downlink.

[0093] In the embodiments of the present application, the frequencies can be divided from low to high into: low frequency band (LB), middle frequency band (MB), high frequency band (HB), and ultra-high frequency band (UHB). In some examples, LB is a frequency band with a frequency range of 600 MHz to 1000 MHz, MB is a frequency band with a frequency range of 1000 MHz to 2100 MHz, HB is a frequency band with a frequency range of 2300 MHz to 2690 MHz, and UHB is a frequency band with a frequency range of 3300 MHz to 5000 MHz.

[0097] Next, the communication system provided by the embodiments of the present application will be introduced exemplarily.

[0098] Figure 1 It is a schematic diagram of the architecture of a communication system provided by the embodiments of the present application.

[0099] As Figure 1As shown, the communication system may include a terminal device 100, a network device 200, and a network device 300. The terminal device 100 may be connected and communicate with the network device 200 and the network device 300 through wireless communication technologies. Among them, the wireless communication technologies include, for example but not limited to, Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA) (such as the second generation of mobile communication technology (2G)), Wideband Code Division Multiple Access (WCDMA) (such as the third generation of mobile communication technology (3G)), Long Term Evolution (LTE) (such as the fourth generation of mobile communication technology (4G)), New Radio (NR) (such as the fifth generation of mobile communication technology (5G)), or other future wireless communication technologies such as the sixth generation of mobile communication technology (6G).

[0100] In the embodiments of the present application, the terminal device may be a device with wireless communication functions. The terminal device may also be referred to as a User Equipment (UE), an access terminal, a user unit, a user station, a mobile station, a mobile device, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. The terminal device in the embodiments of the present application may be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver functions, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a handheld device, a vehicle-mounted device, a wearable device, etc., which is not limited herein.

[0101] In the embodiments of the present application, the network device may be a device with wireless communication capabilities. In one implementation, the network device is an access network device, such as, but not limited to: a base station, a user equipment (UE), a wireless access point (AP), a transmission and receiver point (TRP), a relay device, or other network devices with the functions of a base station, etc. The embodiments of the present application do not limit the specific device form of the network device. Among them, a base station is a device deployed in a radio access network (RAN) for providing wireless communication functions. In different wireless access systems, the name of the base station may be different, such as, but not limited to: a base transceiver station (BTS) in GSM or CDMA, a Node B (NB) in WCDMA, an evolved Node B (eNodeB / eNB) in LTE, and may also be a next-generation base station (g Node B, gNB) in NR, or a base station in other future network systems. The embodiments of the present application do not limit the specific wireless access technology adopted by the network device (which can also be understood as the wireless access type of the network device, or the system type of the network device).

[0102] As Figure 1 shown, the terminal device 100 can be connected and communicate with the network device 200 and the network device 300 at the same time. In one implementation, the network device 200 and the network device 300 may be of the same system type. For example, both are network devices of the LTE system, or both are network devices of the NR system. In another implementation, the network device 200 and the network device 300 may also be of different system types. For example, the network device 200 is a network device of the LTE system, and the network device 300 is a network device of the NR system. The terminal device 100 being connected and communicating with the network device 200 and the network device 300 at the same time can be referred to as the terminal device 100 achieving dual connectivity (DC) of LTE and NR. In one implementation, the communication system may be in a non-standalone (NSA) mode. NSA may be in the form of dual connectivity of LTE and NR. In a communication system in the NSA mode, the terminal device 100 often needs to perform simultaneous transmission and reception of dual system types of NR and LTE, that is, signals of the NR system type and signals of the LTE system type may be transmitted or received simultaneously.

[0103] As Figure 1As shown, the terminal device 100 can be provided with multiple network interfaces and simultaneously connect and communicate with at least one network device (such as network device 200 and / or network device 300) through multiple network interfaces. A network interface in an embodiment of the present application can be understood as corresponding to a network card or a subscriber identification module (SIM) card. In an embodiment of the present application, an example is given where a network interface corresponds to a SIM card. Therefore, the terminal device 100 being provided with multiple network interfaces means that the terminal device 100 includes multiple SIM cards. In an embodiment of the present application, an example is given where the terminal device 100 includes two SIM cards (SIM card 1 and SIM card 2). In one implementation, SIM card 1 and SIM card 1 can belong to the same operator or can belong to different operators respectively. In one implementation, SIM card 1 and SIM card 2 can belong to the same standard, for example, both belong to LTE, or both belong to NR. In another implementation, SIM card 1 and SIM card 2 can also belong to different standards. For example, SIM card 1 belongs to LTE and SIM card 2 belongs to NR. When the terminal device 100 communicates through SIM card 1 and SIM card 2 simultaneously, dual-SIM dual-active (DSDA) can be achieved. In one implementation, the terminal device 100 can use SIM card 1 as the primary card and SIM card 2 as the secondary card. In some examples, the primary card can be the SIM card through which the terminal device 100 currently conducts services such as traffic usage and voice calls, and can be used to send signals (i.e., perform uplink communication) to the network device 200 / network device 300, and can also be used to receive signals from the network device 200 / network device 300 (i.e., perform downlink communication). The secondary card can be used as the SIM card for monitoring signals and is used to receive signals from the network device 200 / network device 300 (i.e., perform downlink communication). In one implementation, SIM card 1 and SIM card 2 of the terminal device 100 can share the same communication system to achieve signal transmission and reception. For example, they share the Figure 2 radio frequency system 130 and antenna system 140 in the terminal device 100 shown.

[0104] In one implementation, the terminal device 100 can combine carriers of multiple frequency bands for communication, that is, achieve carrier aggregation (CA).

[0105] Figure 1 Taking the terminal device 100 as a mobile phone and the network devices 200 and 300 as base stations as an example for illustration, in specific implementation, it can also be in other forms, can also include more terminal devices, and can also include more network devices. The embodiments of the present application do not limit the forms and quantities of the terminal devices and network devices.

[0106] Next, an exemplary introduction to the terminal device 100 provided in the embodiments of the present application will be given.

[0107] It can be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the terminal device 100. In other embodiments of the present application, the terminal device 100 may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0108] Figure 2 It is a schematic structural diagram of a terminal device 100 provided in the embodiments of the present application.

[0109] As Figure 2 shown, the terminal device 100 may include a processor 110, a memory 120, a radio frequency system 130, an antenna (ANT) system 140, a power amplifier (PA) power supply 150, and a system power supply 160. Among them:

[0110] The processor 110 may include one or more processing units. For example, the processor 110 may include an application processor (AP), a modulation and demodulation processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a digital signal processor (DSP), a video codec, a neural-network processing unit (NPU), and / or a baseband processor, etc. Among them, different processing units may be independent devices or integrated in one or more processors.

[0111] The processor 110 may be used to process signals to be transmitted and received signals. In one implementation, the baseband processor may be used to process (such as encode) audio, image, or other data signals of the terminal device 100 and transmit the processed baseband signal to the radio frequency system 130 for transmission. The baseband processor may also be used to receive a baseband signal from the radio frequency system 130 and process (such as decode) the received baseband signal to obtain corresponding audio, image, or other data signals. Optionally, the baseband processor may send the obtained audio, image, or other data signals to the application processor, and the application processor may output an audio signal through an audio device (such as a speaker, a receiver, etc.) (not shown) or display an image through a display screen (not shown).

[0112] The memory 120 may include a volatile memory, such as a random access memory (RAM). The memory 120 may also include a non-volatile memory, such as a read-only memory (ROM), a flash memory, a hard disk drive (HDD), or a solid state disk (SSD). The memory 120 may also include a combination of the above types of memories. In the embodiments of the present application, the memory 120 may also be a storage array, etc. The memory 120 can be used to store computer-executable program codes, and the computer-executable program codes may include instructions. The processor 110 can execute various functional applications and data processing of the terminal device 100 by running the instructions stored in the memory 120 and / or the instructions stored in the memory provided in the processor 110.

[0113] The radio frequency system 130 may include a radio frequency integrated circuit (RFIC) 131, a PA 132, and a front end module (FEM) 133.

[0114] The RFIC 131 may include a multi-stage amplifier, etc., for implementing the processing of various radio frequency front-end signals, as well as control processing related to power, frequency, and gain, and may also be used to implement compensation for various radio frequency performances. The RFIC 131 may include multiple signal transmission channels (Channels), and these multiple signal transmission channels may include at least one transmit channel (TX Channel) and at least one receive channel (RX Channel). The transmit channel can be used to transmit signals, and optionally can also be used to receive signals. The receive channel can be used to receive signals, and optionally can also be used to receive signals. In the embodiments of the present application, the transmit channel is used to transmit signals and the receive channel is used to receive signals as an example for description. Figure 2Taking the example that RFIC131 includes two transmission channels (i.e., transmission channel 1 and transmission channel 2) for illustration. In one implementation, any one of the transmission channels included in RFIC131 may include a phase-locked loop (PLL), a digital front end (DFE), and an analog front-end (AFE). Among them, PLL is a negative feedback system that uses automatic phase adjustment to eliminate frequency errors and achieve error-free and frequency-tracking. The transmission frequency of the radio frequency signal needs to rely on PLL to lock the corresponding frequency point. DFE can be used to provide high-speed analog-to-digital (AD) / digital-to-analog (DA) conversion, in-phase quadrature (IQ) rate conversion between the baseband processor, etc. AFE can be used to implement the processing of digital signals into analog signals. The signal processed by PLL can be sent to DFE for processing, the signal processed by DFE is then sent to AFE for processing, and the signal processed by AFE can be sent to PA132 for amplification.

[0115] PA132 can be used to amplify the signal to be transmitted so that the signal can be transmitted farther. PA is the main part of the transmission system. In the pre-stage circuit of the transmitter, the radio frequency signal generated by the modulation oscillation circuit is relatively weak and cannot be transmitted over a long distance. It needs to be amplified by PA before it can be normally transmitted and received by devices such as base stations and receivers. There may be one or more PA132s. Different frequency bands will use different and independent PAs, that is, signals of different frequency bands will be sent to different PAs for amplification. For example, PA132 may include at least one LBPA (for amplifying LB signals), at least one MBPA (for amplifying MB signals), at least one HBPA (for amplifying HB signals), and at least one UHBPA (for amplifying UHB signals).

[0116] FEM133 can be a radio frequency front-end switch, which is used to connect at least one antenna in PA132 and the antenna system 140, and can realize the switching of the radio frequency signal of PA132 between antennas, so as to send the radio frequency signal of PA132 through the selected antenna.

[0117] The antenna system 140 may include at least one antenna (ANT). Each antenna can be used to transmit and receive electromagnetic wave signals. Each antenna can be used to cover a single or multiple communication frequency bands. Different antennas can also be multiplexed to improve the utilization rate of the antennas.

[0118] In one embodiment, the processor 110 may send the signal to be transmitted to the transmission channel of the RFIC 131 in the radio frequency system 130. The transmission channel may process the signal and then send it to the PA 132 corresponding to the frequency of the signal. For example, when the signal is a low-frequency signal, it will be sent to the LBPA. After the PA 132 amplifies the signal, it will be sent to the corresponding antenna in the antenna system 140 through the FEM 133, and the signal will be transmitted by the antenna. In another embodiment, the antenna in the antenna system 140 may receive the signal, and the signal may be sent to the processor 110 after being processed by the receiving channel of the RFIC 131 in the radio frequency system 130.

[0119] The PA power supply 150 may be connected to the PA 132 and supply power to the PA 132 (for example, provide the supply voltage (volt current condenser, VCC)). There may be one or more PA power supplies 150. One PA power supply 150 supplies power to one or more PAs 132. In one embodiment, one PA power supply 150 may be used to supply power to the PAs 132 of one frequency band, for example, to supply power to at least one UHBPA. In another embodiment, one PA power supply 150 may be used to supply power to the PAs 132 of multiple frequency bands, for example, to supply power to at least one HBPA and at least one UHBPA.

[0120] It can be understood that the power supply voltages required by the PAs 132 of different frequency bands are different, and the efficiency of using the same PA power supply 150 to supply power to the PAs 132 of different frequency bands simultaneously is very low. In one embodiment, the PA power supply 150 may be a switching power supply. When one PA power supply 150 is used to supply power to multiple PAs 132 (including PAs 132 of multiple frequency bands), the PA power supply 150 may switch the connected PAs 132 at different times, so as to supply power to different PAs 132 at different times. For example, the PA power supply 150 switches to supply power to the HBPA at time 1 and switches to supply power to the UHBPA at time 2.

[0121] Exemplarily, the PA power supply 150 is a direct current (DC) to direct current (DC to DC) power supply. The DC to DC power supply can achieve the conversion of different DC power values and can convert the electrical energy of one voltage value into the electrical energy of another voltage value in a DC circuit. Without limitation, the PA power supply 150 may also be an average power tracking (APT) power supply, an envelope tracking (ET) power supply, or a power supply of APT + ET. The embodiments of the present application do not limit the type of the PA power supply 150.

[0122] The system power supply 160 can be connected to the processor 110, the memory 120, and the radio frequency system 130 to supply power.

[0123] In the embodiments of the present application, when the terminal device 100 implements single-channel transmission (1 transmit, 1T), it will output from one of the transmission channels in the RFIC 131 (assumed to be transmission channel 1). Transmission channel 1 sends a signal of a certain frequency band to the PA 132 of that frequency band at one time. Moreover, the PA 132 of this frequency band can be powered by a separate PA power supply 150. Understandably, the PAs 132 of different frequency bands receive signals of different frequency bands sent by different transmission channels, and the PAs 132 of different frequency bands receive different power supply voltages provided by different PA power supplies 150. Therefore, if the terminal device 100 wants to implement dual-channel transmission (2 transmit, 2T) concurrency (i.e., simultaneously transmit signals of two frequency bands), it needs to output from two transmission channels in the RFIC 131 at the same time, and use two different PAs 132 to send to different antennas. Moreover, these two PAs 132 need to be powered by different PA power supplies 150.

[0124] For the convenience of description, the structure of the terminal device 100 in the following examples only shows some or all of the antennas in the radio frequency system 130 and the antenna system 140 of the terminal device 100.

[0125] Currently, due to cost limitations, the radio frequency system 130 of the terminal device 100 generally includes a 1T module for sub-3G (including 1 PA for LB, MB, and HB each) and a 1T module for sub-6G (including 1 UHB PA), that is, it includes 1 PA for LB, MB, HB, and UHB each, which can be simply referred to as a single uplink front-end architecture. For specific examples, please refer to the following Figure 3 。

[0126] Figure 3 It is a schematic structural diagram of another terminal device 100 provided by the embodiments of the present application.

[0127] As Figure 3 shown, the radio frequency system 130 of the terminal device 100 may include an RFIC 131 (including transmission channel 1 and transmission channel 2), a PA 132A for LB, a PA 132B for MB, a PA 132C for HB, and a PA 132D for UHB. Among them, transmission channel 1 is connected to the PAs 132A and 132B, and transmission channel 2 is connected to the PAs 132C and 132D. The PAs 132B and 132C can be coupled together, which can be understood as a single chip supporting MB and HB concurrency. However, this is not limited to this. In another implementation manner, the PAs 132B and 132C can also be independent of each other, which can be understood as two chips respectively supporting MB and HB. The embodiments of the present application do not limit whether the multiple PAs 132 of the terminal device 100 are coupled and the coupling manner.

[0128] In the radio frequency system 130 of the terminal device 100, each PA 132 can be connected to an FEM, and through the FEM, it is connected to at least one antenna (ANT) in the antenna system 140 of the terminal device 100. As Figure 3 shown, the PA 132A of LB is connected through the FEM 133A and the ANT 141, the PA 132B of MB is connected through the FEM 133B and the ANT 142, the PA 132C of HB is connected through the FEM 133C and the ANT 143, and the PA 132D of UHB is connected through the FEM 133D and the ANT 144. It can be understood that for the sake of concise description, the embodiments of the present application take an example of one FEM connected to one ANT for illustration. However, in specific implementation, one FEM can be connected to multiple ANTs, and one PA can select the transmitting antenna to be used through the connected FEM.

[0129] As Figure 3 shown, the terminal device 100 may include a PA power supply 150A and a PA power supply 150B. The PA power supply 150A can be connected to the PA 132A of LB and the PA 132B of MB, and supply power to the PA 132A / PA 132B at any time. The PA power supply 150B can be connected to the PA 132C of HB and the PA 132D of UHB, and supply power to the PA 132C / PA 132D at any time.

[0130] Based on the above description of 2T, when realizing the concurrency of signals of two frequency bands, the signals of these two frequency bands need to be output to two PAs corresponding to the frequency bands through two transmitting channels. Moreover, these two PAs need to be powered by different PA power supplies. Therefore, Figure 3 the terminal device 100 shown can support the following 2T concurrency specifications:

[0131] First, the 2T concurrency of the LB signal and the HB signal, which can be abbreviated as LB+HB. For the sake of simplified description, subsequent descriptions of 2T concurrency will be carried out in accordance with such an abbreviation method. In the scenario of LB+HB, the LB signal can be output to the PA 132A through the transmitting channel 1, and sent to the ANT 141 through the PA 132A for transmission. The HB signal can be output to the PA 132C through the transmitting channel 2, and sent to the ANT 143 through the PA 132C for transmission. It can be abbreviated as the LB signal using the transmitting channel 1, the PA 132A, and the ANT 141, and the HB signal using the transmitting channel 2, the PA 132C, and the ANT 143. Moreover, the PA 132A is powered by the PA power supply 150A, and the PA 132C is powered by the PA power supply 150B.

[0132] Second, LB + UHB. In this scenario, the LB signal uses transmission channel 1, PA132A, and ANT141, and the UHB signal uses transmission channel 2, PA132D, and ANT144. Moreover, PA132A is powered by PA power supply 150A, and PA132D is powered by PA power supply 150B.

[0133] Third, MB + HB. In this scenario, the MB signal uses transmission channel 1, PA132B, and ANT142, and the HB signal uses transmission channel 2, PA132C, and ANT143. Moreover, PA132B is powered by PA power supply 150A, and PA132C is powered by PA power supply 150B. The concurrent specifications of MB + HB are, for example, NSA of B3 + N41, B39 + N41.

[0134] Fourth, MB + UHB. In this scenario, the MB signal uses transmission channel 1, PA132B, and ANT142, and the UHB signal uses transmission channel 2, PA132D, and ANT144. Moreover, PA132B is powered by PA power supply 150A, and PA132D is powered by PA power supply 150B.

[0135] It can be seen that Figure 3 Since the PA132C of HB and the PA132D of UHB in the shown terminal device 100 share the same transmission channel 2 and the same PA power supply 150B, when implementing the HB + UHB scenario, problems such as transmission channel conflict and PA power supply conflict will occur, that is, the concurrent specifications of HB + UHB cannot be supported. For example, NSA of B7 + N77, CA from N41A to N79A, DSDA of main card N78 + sub - card N41, etc. cannot be supported, resulting in limited communication scenarios and poor user experience.

[0136] Figure 4 It is a schematic structural diagram of another terminal device 100 provided by an embodiment of the present application.

[0137] Compared with Figure 3 the shown terminal device 100 (including a 1T module for sub3G and a 1T module for sub6G), Figure 4 the shown terminal device 100 includes a 2T module for sub3G and a 2T module for sub6G. As Figure 4As shown in the figure, the 2T module of sub3G of the terminal device 100 includes PA132A of LB, PA132B of MB, PA132C of HB, PA132E of MB, and PA132F of HB, that is, it includes 2 MB PAs and 2 HB PAs. The 2T module of sub6G of the terminal device 100 includes PA132D of UHB and PA132G of UHB, that is, it includes 2 UHB PAs. Among them, PA132B of MB and PA132C of HB are coupled together (which can be simply referred to as MHB1), and PA132E of MB and PA132F of HB are coupled together (which can be simply referred to as MHB2).

[0138] As Figure 4 shown in the figure, PA132A of LB is connected to ANT141 through FEM133A, MHB1 is connected to ANT142 / ANT143 through FEM133B / FEM133C, MHB2 is connected to ANT145 through FEM133E, PA132G of UHB is connected to ANT146 through FEM133F, and PA132D of UHB is connected to ANT144 through FEM133D. Here, only FEM133B / FEM133C and ANT142 / ANT143 are used as examples. In specific implementations, MHB1 can also be connected to other FEMs and other ANTs.

[0139] As Figure 4 shown in the figure, the transmission channel 1 in RFIC131 of the terminal device 100 is connected to PA132A of LB, MHB1, and PA132G of UHB, and the transmission channel 2 is connected to MHB2 and PA132D of UHB.

[0140] As Figure 4 shown in the figure, the PA power supply 150A of the terminal device 100 can be connected to PA132A of LB, MHB1, and PA132G of UHB, and supply power to PA132A / MHB1 / PA132G at any time. The PA power supply 150B can be connected to MHB2 and PA132D of UHB, and supply power to MHB2 / PA132D at any time.

[0141] It can be seen that Figure 4 the terminal device 100 shown in the figure can not only support Figure 3 the 2T concurrent specifications supported by the terminal device 100 shown in the figure: LB+HB, LB+UHB, MB+HB, MB+UHB, but also support Figure 3 the 2T concurrent specification not supported by the terminal device 100 shown in the figure: HB+UHB. As Figure 4As shown, in the scenario of HB + UHB, the HB signal can use Transmit Channel 1, PA132C in MHB1, and ANT142 / ANT143, and the UHB signal can use Transmit Channel 2, PA132D, and ANT144. Alternatively, the HB signal can use Transmit Channel 2, PA132F in MHB2, and ANT145, and the UHB signal can use Transmit Channel 1, PA132G, and ANT146. However, compared with Figure 3 the terminal device 100 shown, Figure 4 the terminal device 100 shown adds one PA each for MB, HB, and UHB additionally, resulting in a high cost and it is difficult to implement in actual terminal devices.

[0142] The embodiments of the present application provide related devices for radio frequency communication, such as radio frequency systems, terminal devices 100 including radio frequency systems, etc. radio frequency communication devices. The embodiments of the present application can add hardware modules with lower costs (such as PA power supplies, FEMs, PA power switches, transmit channels) in a radio frequency system (such as Figure 3 the radio frequency system 130 shown), rather than adding PAs with higher costs (such as Figure 4 the terminal device 100 shown adds PAs for MB, HB, and UHB), enabling radio frequency communication devices with limited costs (with the above single uplink front-end architecture) to also support more concurrent frequency band capabilities, such as various concurrent frequency band capabilities like MB + HB, LB + MB, MB + UHB, LB + UHB, HB + UHB, etc., broadening the communication scenario and enhancing the user's communication experience, thereby enhancing the user's competitiveness.

[0143] Next, the radio frequency system and the terminal device 100 including the radio frequency system provided by the embodiments of the present application are introduced exemplarily. The embodiments of the present application take adding hardware modules with lower costs in Figure 3 the terminal device 100 (including the radio frequency system 130) shown as an example for illustration. It can be understood that the structure of the terminal device 100 in the following example is similar to the structure of Figure 3 the terminal device 100 shown, and the following example of the terminal device 100 mainly elaborates on the differences from Figure 3 the terminal device 100 shown.

[0144] Embodiment 1: In Figure 3 the terminal device 100 shown, 1 piece (pcs) of PA power supply is added to supply power to PA132C of HB alone, and 1 pcs of FEM is added to enable the transmit channel connected to PA132C of HB to switch between Transmit Channel 1 and Transmit Channel 2, that is, to enable the transmit channel used by the HB signal to switch between Transmit Channel 1 and Transmit Channel 2. The structure at this time can be seen in the following Figure 5 .

[0145] Figure 5 It is a schematic structural diagram of another terminal device 100 provided by an embodiment of the present application. Compared with Figure 3 the terminal device 100 shown, Figure 5 the terminal device 100 shown further includes a PA power supply 171 and a FEM 172, that is, the PA power supply 171 and the FEM 172 are newly added modules.

[0146] As Figure 5 shown, the PA power supply 150A can be connected to the PA132A of the LB and the PA132B of the MB, and supply power to the PA132A / PA132B at any time. The PA power supply 150B can be connected to the PA132D of the UHB and supply power to the PA132D alone. The PA power supply 171 can be connected to the PA132C of the HB and supply power to the PA132C alone.

[0147] As Figure 5 shown, both the PA132A of the LB and the PA132B of the MB are connected to the transmission channel 1, the PA132D of the UHB is connected to the transmission channel 2, and the PA132C of the HB is connected to the transmission channel 1 / transmission channel 2 through the FEM 172. It is possible to control the FEM 172 to switch whether the PA132C is connected to the transmission channel 1 or the transmission channel 2, which can also be referred to as controlling whether the FEM 172 connects to the transmission channel 1 or the transmission channel 2.

[0148] Figure 5 For the concurrent specifications that the terminal device 100 shown can achieve, as well as the usage status of the transmission channels, the usage status of the PA power supply, and the status of the FEM 172 in the scenarios of each concurrent specification, please refer to Table 1 below for details.

[0149] Table 1

[0150]

[0151] As shown in Table 1, in the scenario of MB+HB, the MB signal can be output to the PA132B of the MB through the transmission channel 1, amplified by the PA132B and sent to the ANT142 through the FEM133B, and the amplified MB signal is transmitted by the ANT142. The PA132B is powered by the PA power supply 150A. At the same time, it is possible to control the newly added FEM 172 to connect the PA132C of the HB and the transmission channel 2. The HB signal can be output to the PA132C through the transmission channel 2, amplified by the PA132C and sent to the ANT143 through the FEM133C, and the amplified HB signal is transmitted by the ANT143. The PA132C is powered by the newly added PA power supply 171.

[0152] As shown in Table 1, in the LB+HB scenario, the LB signal can be output to PA132A of LB through transmission channel 1, amplified by PA132A and sent to ANT141 through FEM133A. The amplified LB signal is transmitted by ANT141. PA132A is powered by PA power supply 150A. At the same time, it is possible to control the newly added FEM172 to connect PA132C of HB and transmission channel 2. The HB signal can be output to PA132C through transmission channel 2, amplified by PA132C and sent to ANT143 through FEM133C. The amplified HB signal is transmitted by ANT143.

[0153] As shown in Table 1, in the UHB+HB scenario, the UHB signal can be output to PA132D of UHB through transmission channel 2, amplified by PA132D and sent to ANT144 through FEM133D. The amplified UHB signal is transmitted by ANT144. PA132D is powered by PA power supply 150B.

At the same time, the LB signal can be output to PA132A of LB through transmission channel 1, amplified by PA132A and sent to ANT141 through FEM133A. The amplified LB signal is transmitted by ANT141. PA132A is powered by PA power supply 150A.

[0155] As shown in Table 1, in the UHB+MB scenario, the UHB signal can be output to PA132D of UHB through transmission channel 2, amplified by PA132D and sent to ANT144 through FEM133D.

PA132B is powered by PA power supply 150A.

[0156] FromFigure 5 It can be seen that the terminal device 100 with a single uplink front-end architecture can add one PA power supply and one FEM with relatively low cost, and by flexibly allocating the PAs powered by the three PA power supplies and flexibly switching the transmission channels to which PA132C of HB is connected, it can support the 2T concurrent specification of multiple frequency band combinations such as MB+HB, LB+HB, UHB+HB, UHB+LB, and UHB+MB, that is, it newly supports Figure 3 the 2T concurrent specification that the shown terminal device 100 does not support: HB+UHB, thereby covering multiple scenarios such as NSA, CA, and DSDA.

The structure at this time can be seen in the following Figure 6 .

[0158] Figure 6 is a schematic structural diagram of another terminal device 100 provided by an embodiment of the present application.

The PA power supply 150B can be connected to PA132D of UHB and separately power PA132D. The PA power supply 173 can be connected to PA132B of MB and separately power PA132B.

[0160] As Figure 6 shown, both PA132A of LB and PA132C of HB are connected to transmission channel 1, PA132D of UHB is connected to transmission channel 2, and PA132B of MB is connected to transmission channel 1 / transmission channel 2 through FEM174. It is possible to control FEM174 to switch whether PA132B is connected to transmission channel 1 or transmission channel 2, which can also be referred to as controlling FEM174 to connect (also referred to as select) transmission channel 1 or transmission channel 2.

[0161] Figure 6The concurrent specifications that the terminal device 100 shown can achieve, as well as the usage status of the transmission channels, the usage status of the PA power supply, and the status of the FEM 174 in the scenarios of each concurrent specification, can be specifically referred to in Table 2 below.

[0164]

[0166] As shown in Table 2, in the MB + LB scenario, the newly added FEM 174 can be controlled to connect to the PA 132B of MB and the transmission channel 2. The MB signal can be output through the transmission channel 2 to the PA 132B of MB, amplified by the PA 132B, and then sent to the ANT 142 through the FEM 133B. The amplified MB signal is transmitted by the ANT 142. The PA 132B is powered by the newly added PA power supply 173.
