[0037] Example 1

[0038] like Figures 1 to 5 As shown, the first aspect of this application provides a radio frequency processing module 1, including: a first path 11 and a second path 12; the first path 11 is used to process a first transmission signal located in a first frequency band; the second path 12 is connected to the first path 11 through a first adjustment component 13 so that the second path 12 can process a second transmission signal located in a second frequency band and / or a third transmission signal located in a third frequency band; the second frequency band and the third frequency band are different.

[0039] Specifically, this application enables the transmission of multiple transmission signals of multiple frequency bands and different combinations of transmission signals through the first path 11 and the second path 12. Compared with the one-to-one correspondence between the signal transmission path and the frequency band of the signal, this reduces the number of paths required and saves the cost and layout space required for the communication device.

[0040] The second path 12 is connected to the first path 11 through the first adjustment component 13, so that the second path 12 can simultaneously process the second transmission signal located in the second frequency band and the third transmission signal located in the third frequency band. The first adjustment component 13 may include an adjustable phase shifter to enable carrier aggregation of the second and third transmission signals with different frequency bands during transmission, or the second path 12 can process only the second transmission signal or only the third transmission signal. Thus, through the setting of the first adjustment component 13, the radio frequency processing module 1 can adjust the connection state between the first path 11 and the second path 12 according to the actual dynamic requirements of signal transmission, thereby achieving more efficient signal transmission resource management and utilization.

[0041] In one embodiment, the first frequency band is the n77 band, the second frequency band is the n79 band, and the third frequency band is the n78 band. The operating frequency of the n77 band is 3.3-4.2 GHz, the operating frequency of the n79 band is 4.4-5.0 GHz, and the operating frequency of the n78 band is 3.3-3.8 GHz. The first path 11 is capable of processing a first transmission signal located in the n77 band, and the second path 12 is capable of processing a second transmission signal located in the n79 band and / or a third transmission signal located in the n78 band. In this embodiment, when the first adjustment component 13 is disconnected, there is no electrical connection between the first path 11 and the second path 12. The first path 11 is capable of processing the first transmission signal located in the n77 band, and the second path 12 is capable of processing the third transmission signal located in the n78 band. Path 12 can only process the second transmission signal located in the n79 frequency band; when the first adjustment component 13 is closed, the first path 11 and the second path 12 are electrically connected, and the second path 12 can process the second transmission signal located in the n79 frequency band and the third transmission signal located in the n78 frequency band at the same time, or it can process only the second transmission signal located in the n79 frequency band or the third transmission signal located in the n78 frequency band. Thus, the signal transmission path does not need to be set to correspond one-to-one with the frequency band of the transmission signal. The transmission of the second transmission signal located in the n79 frequency band and the third transmission signal located in the n78 frequency band can be realized only through the second path 12, saving the cost and layout space required for the communication device.

[0042] In another embodiment, the first frequency band is the n257 band, the second frequency band is the n260 band, and the third frequency band is the n261 band. The operating frequency of the n257 band is 26.5-29.5 GHz, the operating frequency of the n260 band is 37.0-40.0 GHz, and the operating frequency of the n261 band is 27.5-28.35 GHz. The first path 11 can process a first transmission signal located in the n257 band, and the second path 12 can process a second transmission signal located in the n260 band and / or a third transmission signal located in the n261 band. In this embodiment, when the first adjustment component 13 is disconnected, there is no electrical connection between the first path 11 and the second path 12. The first path 11 can process the signal located in the n257 band. The first transmission signal in the n257 frequency band, the second path 12 can only process the second transmission signal located in the n260 frequency band; when the first adjustment component 13 is closed, the first path 11 and the second path 12 are electrically connected, and the second path 12 can process the second transmission signal located in the n260 frequency band and the third transmission signal located in the n261 frequency band at the same time, or it can process only the second transmission signal located in the n260 frequency band or the third transmission signal located in the n261 frequency band. Thus, the signal transmission path does not need to be set to correspond one-to-one with the frequency band of the transmission signal, and the transmission of the second transmission signal located in the n260 frequency band and the third transmission signal located in the n261 frequency band can be realized only through the second path 12.

[0043] This application provides a radio frequency processing module 1, including: a first path 11 and a second path 12; the first path 11 is used to process a first transmission signal located in a first frequency band; the second path 12 is connected to the first path 11 through a first adjustment component 13, so that the second path 12 can process a second transmission signal located in a second frequency band and / or a third transmission signal located in a third frequency band; the second frequency band and the third frequency band are different. This application, through the setting of the first adjustment component 13, enables the transmission of multiple transmission signals in multiple frequency bands, as well as different combinations of transmission signals, through the first path 11 and the second path 12. Compared with a one-to-one correspondence between signal transmission paths and signal frequency bands, this reduces the number of paths required, saves the cost and layout space required for the communication device, and solves the technical problem that an increase in the types of frequency bands that the communication device needs to process, coupled with an increase in the number of corresponding signal transmission paths, is detrimental to device cost and space layout.

[0044] like Figures 1 to 5 As shown, in some embodiments, the first adjustment component 13 has a switchable first state and a second state; in the first state, the first path 11 and the second path 12 are electrically connected, and the second path 12 is capable of processing a second transmission signal and / or a third transmission signal; in the second state, the first path 11 and the second path 12 are not electrically connected, and the second path 12 is only capable of processing the second transmission signal.

[0045] Specifically, the first adjustment component 13 in this application has a switchable first state and a second state, enabling the radio frequency processing module 1 to dynamically adjust resource allocation according to the actual needs of signal transmission. When it is necessary to simultaneously process the transmission of a second transmission signal and a third transmission signal located in two different frequency bands, the first adjustment component 13 can be placed in the closed first state, making the first path 11 and the second path 12 electrically connected, thereby realizing the coordinated processing of multi-frequency band signals, which not only improves spectrum utilization but also enhances the flexibility of signal transmission. Furthermore, in a high-density communication environment, the first state of the first adjustment component 13 in this application can realize the transmission of signals in multiple frequency bands to meet user needs. Moreover, when only transmitting the second transmission signal located in the second frequency band, or only transmitting the third transmission signal located in the third frequency band, the first adjustment component 13 being placed in the closed first state can also enable the second transmission signal to be transmitted through the second path 12, or enable the third transmission signal to be transmitted through the second path 12.

[0046] When the first adjustment component 13 is in the disconnected second state, the first path 11 and the second path 12 are not electrically connected. The second path 12 can only process the second transmission signal, thereby reducing unnecessary path complexity and signal transmission power consumption. In low-load communication environments, the radio frequency processing module 1 can be simplified to single-band operation to save energy and reduce interference.

[0047] Furthermore, in the signals transmitted by the first path 11 and the second path 12 of the radio frequency processing module 1 of this application, the first transmission signal includes a first transmit signal and a first receive signal, the second transmission signal includes a second transmit signal and a second receive signal, and the third transmission signal includes a third transmit signal and a third receive signal. That is, in this application, the first path 11 and the second path 12 can receive signals transmitted by the antenna assembly and can also transmit signals transmitted to the antenna assembly.

[0048] like Figures 1 to 5 As shown, in some embodiments, the first path 11 includes a first transmission port 111, a first switching assembly 112, and a first filter 113; the first transmission port 111 is connected through the first switching assembly 112 and the first filter 113; in a second state, the first filter 113 is used to process a first transmission signal located in a first frequency band; or, the first filter 113 is used to process a third transmission signal located in a third frequency band; the third frequency band is a subset of the first frequency band.

[0049] Specifically, in order to optimize the spectrum resource utilization of the radio frequency processing module 1, this application can set the third frequency band as a subset of the first frequency band, so that the first transmission signal located in the first frequency band and the third transmission signal located in the third frequency band can be transmitted through the first path 11, so that the first path 11 can be reused, reducing the number of paths required to be arranged, saving the cost and layout space required for the communication device arrangement. In one embodiment, the first frequency band is the n77 band, and the third frequency band is the n78 band. The operating frequency of the n77 band is 3.3-4.2 GHz, and the operating frequency of the n78 band is 3.3-3.8 GHz. The n78 band is a subset of the n77 band. The first path 11 can transmit both the first transmission signal located in the n77 band and the third transmission signal located in the n78 band. In another embodiment, the first frequency band is the n257 band, and the third frequency band is the n261 band. The operating frequency of the n257 band is 26.5-29.5 GHz, and the operating frequency of the n261 band is 27.5-28.35 GHz. The n261 band is a subset of the n257 band. The first path 11 can transmit both the first transmission signal located in the n257 band and the third transmission signal located in the n261 band.

[0050] The first path 11 of this application includes a first transmitting port 111, a first switching assembly 112, and a first filter 113. The first transmitting port 111 can be connected to a radio frequency front-end module in a communication device to transmit signals transmitted from the radio frequency front-end module to the antenna assembly. In the first path 11, the first transmitting port 111 is connected to the first switching assembly 112 and the first filter 113. The first filter 113 can filter the first transmission signal located in the first frequency band, remove unwanted frequency components, reduce interference, and improve the quality and reliability of signal transmission. Since the third frequency band is a subset of the first frequency band, the first filter 113 can also process the third transmission signal located in the third frequency band.

[0051] like Figures 1 to 5 As shown, in some embodiments, the first path 11 further includes a first coupler 114, which is disposed on the side of the first filter 113 away from the first switching assembly 112; the second path 12 includes a second transmit port 121, a second switching assembly 122, a second filter 123, and a second coupler 124. The second transmit port 121 is connected through the second switching assembly 122 and the second filter 123. The second coupler 124 is disposed on the side of the second filter 123 away from the second switching assembly 122. The second filter 123 is used to process the second transmission signal located in the second frequency band.

[0052] Specifically, this application provides a first coupler 114 and a second coupler 124 in the first path 11 and the second path 12, respectively, to monitor signal transmission. Signal samples collected by the first coupler 114 or the second coupler 124 help quickly identify problems such as attenuation and distortion during signal transmission, allowing for timely repair measures. Furthermore, the first coupler 114 and the second coupler 124 can provide feedback information, enabling the transmitter in the communication device to dynamically adjust its transmission power based on the feedback, ensuring efficient and stable signal transmission. Additionally, the RF processing module 1 of this application can connect to test instruments to monitor and evaluate the operating status of the first path 11 and the second path 12, improving maintenance efficiency.

[0053] The second path 12 of this application further includes a second transmit port 121, a second switch assembly 122, and a second filter 123. The second transmit port 121 can be connected to a radio frequency front-end module in a communication device to transmit signals transmitted from the radio frequency front-end module to the antenna assembly. In the second path 12, the second transmit port 121 is connected to the second switch assembly 122 and the second filter 123. The second filter 123 can filter the second transmission signal located in the second frequency band, removing unwanted frequency components, reducing interference, and improving the quality and reliability of signal transmission. In one embodiment, the second switch assembly 122 can be a single-pole double-throw switch, so that the second filter 123 can filter when the signal on the second path 12 is a second transmit signal or a second receive signal.

[0054] like Figures 1 to 5 As shown, in some embodiments, the first adjustment component 13 includes a first adjustable phase shifter 131 and a third switch component 132. The third switch component 132 is connected to the first switch component 112 through a third filter 133. The first adjustable phase shifter 131 is disposed on the second path 12 and located between the second filter 123 and the second coupler 124. The first switch component 112 has switchable third and fourth states, and the third switch component 132 has switchable first and second states. The third state is coordinated with the first state, and the fourth state is coordinated with the second state. In the first state, the third filter 133 is used to process the third transmission signal located in the third frequency band.

[0055] Specifically, the first adjustment component 13 in this application includes a first adjustable phase shifter 131. When the first adjustment component 13 is in a first state, the first path 11 and the second path 12 are electrically connected. The second path 12 can simultaneously transmit a second transmission signal located in the second frequency band and a third transmission signal located in the third frequency band. This application compensates for the phase difference between the second and third transmission signals through the first adjustable phase shifter 131, realizing carrier aggregation between the second and third transmission signals. This allows the two signals to enhance each other rather than cancel each other when superimposed, thereby improving the signal transmission quality of carrier aggregation and reducing the bit error rate. Furthermore, by placing the first adjustable phase shifter 131 on the second path 12 and between the second filter 123 and the second coupler 124, this application also enables the second coupler 124 to monitor the second and third transmission signals after carrier aggregation. This helps to detect problems in a timely manner and take measures, and provides feedback information to ensure efficient and stable signal transmission.

[0056] The third switch component 132 in the first adjustment component 13 is connected to the first switch component 112 on the first path 11 through the third filter 133. The third filter 133 can filter the third transmission signal located in the third frequency band, remove unwanted frequency components, reduce interference, and improve the quality and reliability of the transmission of the third transmission signal. The third switch assembly 132 has a switchable first state and a second state, and the first switch assembly 112 has a switchable third state and a fourth state. This application sets the third state of the first switch assembly 112 to coordinate with the first state of the third switch assembly 132, and the fourth state of the first switch assembly 112 to coordinate with the second state of the third switch assembly 132. That is, when the third switch assembly 132 is in the closed first state, it is electrically connected to the third filter 133, which processes the third transmission signal located in the third frequency band. The first adjustable phase shifter 131 can process both the second and third transmission signals. When the third switch assembly 132 is in the open second state, the first transmit port 111 is electrically connected to the first filter 113 through the first switch assembly 112, and the third filter 133 does not participate in signal transmission. Furthermore, through the coordinated state switching between the first switch assembly 112 and the third switch assembly 132, the radio frequency processing module 1 can flexibly switch and dynamically allocate signal transmission resources, thereby improving signal transmission efficiency. In one embodiment, the first switch assembly 112 in this application may be a double-pole double-throw switch, and the third switch assembly 132 may be a single-pole single-throw switch.

[0057] In one embodiment, when the third switch component 132 is in the open second state, and the radio frequency processing module 1 is in a transmit or receive mode for processing the first transmitted signal located in the first frequency band, such as... Figure 3As shown, in transmit mode, the first transmission signal is transmitted by the RF front-end module, sequentially passing through a double-pole double-throw switch, a first filter 113, a first coupler 114, and an integrated switch assembly 17 before being transmitted to one of the antennas in the antenna assembly. In receive mode, the first transmission signal is transmitted by one of the antennas in the antenna assembly, sequentially passing through the integrated switch assembly 17, the first coupler 114, the first filter 113, and the double-pole double-throw switch, and finally received by the RF front-end module. When the RF processing module 1 is currently processing a third transmission signal located in the third frequency band, the above transmission path is multiplexed.

[0058] In one embodiment, when the third switch component 132 is in the open second state, and the radio frequency processing module 1 is in a transmit or receive mode for processing the second transmission signal located in the second frequency band, such as... Figure 4 As shown, in transmit mode, the second transmission signal is transmitted by the RF front-end module, and sequentially passes through a single-pole double-throw switch, a second filter 123, a first adjustable phase shifter 131, a second coupler 124, and an integrated switch assembly 17 before being transmitted to one of the antennas in the antenna assembly. In receive mode, the second transmission signal is transmitted by one of the antennas in the antenna assembly, and sequentially passes through the integrated switch assembly 17, the second coupler 124, the first adjustable phase shifter 131, the second filter 123, and a single-pole double-throw switch before being received by the RF front-end module.

[0059] In one embodiment, when the third switch component 132 is in a closed first state, and the radio frequency processing module 1 is in a transmit or receive mode that simultaneously processes a second transmission signal located in the second frequency band and a third transmission signal located in the third frequency band, such as... Figure 5 As shown, in transmit mode, the second transmission signal is transmitted by the RF front-end module, passes through a single-pole double-throw switch and a second filter 123 in sequence, and reaches the first adjustable phase shifter 131. The third transmission signal is transmitted by the RF front-end module, passes through a double-pole double-throw switch, a third filter 133, and a third switch assembly 132 in sequence, and reaches the first adjustable phase shifter 131. After carrier aggregation of the second and third transmission signals is achieved by the first adjustable phase shifter 131, the two signals are transmitted to one of the antennas in the antenna assembly through a second coupler 124 and an integrated switch assembly 17 in sequence. In receive mode, the second and third transmission signals are transmitted by one of the antennas in the antenna assembly, pass through an integrated switch assembly 17 and a second coupler 124 in sequence, and reach the first adjustable phase shifter 131. Then, the third transmission signal is transmitted to the RF front-end module through the third switch assembly 132, the third filter 133, and a double-pole double-throw switch in sequence, and the second transmission signal is transmitted to the RF front-end module through the second filter 123 and a single-pole double-throw switch in sequence.

[0060] like Figures 1 to 5As shown, in some embodiments, it further includes: a third path 14 and a fourth path 15, wherein the third path 14 is used to process a fourth transmission signal located in the first frequency band; the fourth path 15 is connected to the third path 14 through the second adjustment component 16 so that the fourth path 15 can process a fifth transmission signal located in the second frequency band and / or a sixth transmission signal located in the third frequency band.

[0061] Specifically, in order to realize the main reception and diversity reception functions of the radio frequency processing module 1 of this application, the radio frequency processing module 1 of this application also includes a third path 14 and a fourth path 15 for diversity reception, so as to form a redundant setting for signal reception, which works together as the first path 11 and the second path 12 for main reception, reducing the call drop rate of signal transmission, avoiding signal transmission interruption, improving the fault tolerance and reliability of signal transmission, and enabling users to enjoy a more stable and smooth signal transmission experience through the coordinated work of main reception and diversity reception, reducing stuttering and disconnection problems.

[0062] In this application, the fourth transmission signal includes the fourth receiving signal, the fifth transmission signal includes the fifth receiving signal, and the sixth transmission signal includes the sixth receiving signal. That is, the signal can be transmitted to the receiving end in parallel through the first path 11, the second path 12, the third path 14, and the fourth path 15, which effectively increases the amount of data transmitted to the receiving end per unit time, increases the channel capacity, and improves signal transmission efficiency and user experience.

[0063] Furthermore, in diversity reception, this application enables the transmission of multiple transmission signals of multiple frequency bands and different combinations of transmission signals through the third path 14 and the fourth path 15 by setting the second adjustment component 16. Compared with the one-to-one correspondence between the signal transmission path and the frequency band of the signal, this reduces the number of paths required and saves the cost and layout space required for the communication device.

[0064] like Figures 1 to 5 As shown, in some embodiments, the third path 14 includes a first receiving port 141, a fourth switching component 142, and a fourth filter 143, with the first receiving port 141 connected to the fourth switching component 142 and the fourth filter 143; the fourth path 15 includes a second receiving port 151 and a fifth filter 152 connected to each other; the second adjustment component 16 includes a second adjustable phase shifter 161 and a fifth switching component 162, with the fifth switching component 162 connected to the fourth switching component 142 via a sixth filter 163, and the second adjustable phase shifter 161 disposed in the fourth path 15 and located on the side of the fifth filter 152 opposite to the second receiving port 151.

[0065] Specifically, in order to achieve diversity reception of signals through the third path 14 and the fourth path 15, the third path 14 of this application includes a first receiving port 141, a fourth switching component 142 and a fourth filter 143, and the fourth path 15 includes a second receiving port 151 and a fifth filter 152 connected to each other. The first receiving port 141 and the second receiving port 151 can be connected to the radio frequency front-end module in the communication device to receive signals transmitted from the antenna component to the radio frequency front-end module. The fourth filter 143 can filter the fourth transmission signal located in the first frequency band, and the fifth filter 152 can filter the fifth transmission signal located in the second frequency band to remove unwanted frequency components, reduce interference, and improve the quality and reliability of signal transmission.

[0066] The second adjustment component 16 includes a second adjustable phase shifter 161 and a fifth switch component 162. The fifth switch component 162 is connected to the fourth switch component 142 via a sixth filter 163. The second adjustable phase shifter 161 is disposed in the fourth path 15 and located on the side of the fifth filter 152 opposite to the second receiving port 151. When the fifth switch component 162 is closed, the third path 14 and the fourth path 15 are electrically connected. The fourth path 15 can simultaneously transmit the fifth transmission signal located in the second frequency band and the sixth transmission signal located in the third frequency band. This application compensates for the phase difference between the fifth and sixth transmission signals by using the second adjustable phase shifter 161, realizing carrier aggregation between the fifth and sixth transmission signals in diversity reception, so that the two signals enhance each other rather than cancel each other when superimposed, thereby improving the signal transmission quality of carrier aggregation and reducing the bit error rate.

[0067] In this application, the fourth switch component 142 can be configured to have switchable fifth and sixth states, and the fifth switch component 162 can have switchable seventh and eighth states. The fifth state works in conjunction with the seventh state, and the sixth state works in conjunction with the eighth state. When the fourth switch component 142 is in the fifth state and the fifth switch component 162 is in the closed seventh state, the first receiving port 141 is electrically connected to the sixth filter 163 through the fourth switch component 142. The sixth filter 163 is used to filter the sixth transmission signal located in the third frequency band, and the second adjustable phase shifter 161 can process both the fifth and sixth transmission signals. When the fourth switch component 142 is in the sixth state and the fifth switch component 162 is in the open eighth state, the first receiving port 141 is electrically connected to the fourth filter 143 through the fourth switch component 142, and the second adjustable phase shifter 161 can only process the fifth transmission signal. Therefore, through the coordinated state switching between the fourth switch component 142 and the fifth switch component 162, the RF processing module 1 can flexibly switch during diversity reception, dynamically allocate signal transmission resources, and improve signal transmission efficiency. In one embodiment, the fourth switch assembly 142 in this application may be a single-pole double-throw switch, and the fifth switch assembly 162 may be a single-pole single-throw switch.

[0068] In one embodiment, when the fifth switching component 162 is in the open eighth state, in order to achieve diversity reception of the fourth transmission signal located in the first frequency band, such as... Figure 3 As shown, the fourth transmission signal is transmitted by another antenna in the antenna assembly, passes sequentially through the integrated switch assembly 17, the fourth filter 143, and the fourth switch assembly 142, and is finally received by the RF front-end module. When diversity reception is performed on the sixth transmission signal located in the third frequency band, the above transmission path is multiplexed. Furthermore, since the third path corresponds to the first path in this application, the transmitted first transmission signal corresponds to the fourth transmission signal, and the third transmission signal corresponds to the sixth transmission signal. Based on the two different antenna transmission signals of the antenna assembly, one antenna in the antenna assembly supports one transmission and one reception in the first or third frequency band, while the other antenna supports one reception in the first or third frequency band. This enables the RF processing module 1 to achieve one transmission and two receptions in the first or third frequency band.

[0069] In one embodiment, when the fifth switching component 162 is in the open eighth state, in order to achieve diversity reception of the fifth transmitted signal located in the second frequency band, such as... Figure 4As shown, the fifth transmission signal is transmitted by another antenna in the antenna assembly, passes sequentially through the integrated switch assembly 17 and the fifth filter 152, and is finally received by the RF front-end module. Furthermore, since the fourth path corresponds to the second path in this application, the transmitted second transmission signal corresponds to the fifth transmission signal. Based on the two different antenna transmission signals of the antenna assembly, one antenna in the antenna assembly supports one transmission and one reception of the second frequency band, while the other antenna supports one reception of the second frequency band. This enables the RF processing module 1 to achieve one transmission and two receptions of the second frequency band.

[0070] In one embodiment, when the fifth switch component 162 is in the closed seventh state, to simultaneously process the diversity reception of the fifth transmission signal located in the second frequency band and the sixth transmission signal located in the third frequency band, the fifth and sixth transmission signals are transmitted by another antenna in the antenna assembly, pass through the integrated switch component 17 to reach the second adjustable phase shifter 161, and then the fifth transmission signal is transmitted to the RF front-end module via the fifth filter 152, and the sixth transmission signal is transmitted to the RF front-end module sequentially via the fifth switch component 162, the sixth filter 163, and the fourth switch component 142. Furthermore, since the fourth path corresponds to the second path in this application, the transmitted second transmission signal corresponds to the fifth transmission signal, and the third transmission signal corresponds to the sixth transmission signal. Based on the two different antenna transmission signals of the antenna assembly, it is realized that one antenna in the antenna assembly supports one transmission and one reception of the second and third frequency bands, and the other antenna supports one reception of the second and third frequency bands, thereby enabling the RF processing module 1 to achieve one transmission and two receptions of the second and third frequency bands.

[0071] like Figures 1 to 5 As shown, in some embodiments, it further includes: an integrated switch assembly 17, one side of which is connected to the first path 11, the second path 12, the third path 14 and the fourth path 15, and the other side of which is used to connect to the antenna assembly.

[0072] Specifically, this application sets up an integrated switch assembly 17, which connects the first path 11, the second path 12, the third path 14 and the fourth path 15 on one side, and connects the antenna assembly on the other side to transmit the signals transmitted or received by the antenna assembly. The integrated switch assembly 17 integrates the connection of multiple paths, reduces the complexity of the paths in the radio frequency processing module 1, simplifies the spatial layout, and enables the radio frequency processing module 1 to flexibly switch to different signal transmission paths to meet the communication requirements of multi-band support. In one embodiment, one side of the integrated switch assembly 17 is connected to the first path 11, the second path 12, the third path 14, and the fourth path 15, and is also connected to SRS_IN (Sounding Reference Signal In). The other side is used to connect to the antenna assembly and is also connected to SRS_OUT (Sounding Reference Signal Out). This is to evaluate the signal quality of the multiple-input multiple-output video processing module during signal transmission through SRS_IN and SRS_OUT, so that the communication device can make reasonable allocation and scheduling of signal transmission resources based on the evaluation results. In this embodiment, the antenna assembly may include two antennas. That is, one side of the integrated switch assembly 17 needs to be connected to the first path 11, the second path 12, the third path 14, the fourth path 15, and SRS_IN, respectively, and the other side needs to be connected to the two antennas and SRS_OUT, respectively. The integrated switch assembly 17 may be a three-pole five-throw switch.

[0075] Specifically, this application provides a communication device including an antenna assembly 2 and a radio frequency (RF) processing module 1 connected together, enabling the RF processing module 1 to process signals transmitted by the antenna assembly 2 or signals received by the antenna assembly 2. When a signal is transmitted to the antenna assembly 2 via the RF processing module, the antenna assembly 2 can efficiently convert the electrical signal into electromagnetic waves and propagate the electromagnetic waves to a predetermined communication coverage area based on the environment set by the communication device. Furthermore, the antenna assembly 2 can also capture electromagnetic waves and convert them into electrical signals for transmission to the RF processing module 1.

This application, by setting the first adjustment component 13 in the RF processing module 1 of the communication device, enables the transmission of multiple transmission signals in multiple frequency bands, as well as signal transmission of different combinations of transmission signals, through the first path 11 and the second path 12, while connected to the antenna assembly 2. Compared to a one-to-one correspondence between signal transmission paths and signal frequency bands, this reduces the number of paths required, saves the cost and layout space required for the communication device, and solves the technical problem that an increase in the types of frequency bands that the communication device needs to process, coupled with an increase in the number of corresponding signal transmission paths, is detrimental to device cost and space layout.

Furthermore, the antenna assembly 2 of this application includes a first antenna 21 and a second antenna 22. The first antenna 21 is used for both transmitting and receiving signals, while the second antenna 22 is only used for transmitting signals, enabling the first antenna 21 to support bidirectional communication for both transmission and reception.

This coordinated operation serves as the first path 11 and the second path 12 for main reception, reducing the call drop rate, avoiding signal transmission interruptions, and improving the fault tolerance and reliability of signal transmission. Through the coordinated operation of main reception and diversity reception, users can enjoy a more stable and smooth signal transmission experience, reducing stuttering and disconnection issues.
