[0032] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In the description of the present application, the meaning of "several" is at least one, such as one, two, etc., unless otherwise clearly and specifically defined.

[0034] The radio frequency module involved in the embodiments of the present application can be applied to a communication device with a wireless communication function, and the communication device can be applied to a communication system with a wireless communication function, such as Figure 1 As shown, the communication system includes a communication device 10 and a network device 20 .

[0035] The network device 20 can provide communication coverage for a specific geographical area, and can communicate with the communication device 10 located in the coverage area. The network device 20 can be a network device 20 (Base Transceiver Station, BTS) in a GSM system or a CDMA system, or a network device 20 (NodeB, NB) in a WCDMA system, or an evolved network device 20 (Evolutional Node B, eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (Cloud Radio Access Network, CRAN), or the network device 20 can be a mobile switching center, a relay station, an access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, a core network in a 5G network, a base station, a fixed station, an advanced base station (ABS), an access point and other network-side devices or a network device 20 in a future evolved public land mobile network (Public Land Mobile Network, PLMN), etc.

[0036] The communication device 10 may be a handheld device, an in-vehicle device, a smart car, a wearable device, a computing device, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE) (e.g., a mobile phone), a mobile station (MS), etc. For the convenience of description, the above-mentioned devices are collectively referred to as the communication device 10.

[0037] In an embodiment of the present application, a radio frequency module is provided, such as Figure 2 As shown, the radio frequency module includes: at least two transmission paths 110 (illustrated as two paths in the figure) and a processing circuit 120.

[0038] At least two transmission paths 110, each transmission path 110 is used to support transmission processing of the radio frequency signal to be transmitted; the processing circuit 120 is configured to control the at least two transmission paths 110 to transmit radio frequency signals of the same data stream when the communication device is in a first channel quality environment, so that the at least two transmission paths 110 support transmission (TX) diversity processing; when the communication device is in a second channel quality environment and the current communication scenario type is a first target scenario type, control the at least two transmission paths 110 to correspondingly transmit radio frequency signals of different data streams, so that the at least two transmission paths 110 support MIMO transmission processing; wherein the second channel quality environment is better than the first channel quality environment.

[0039] Each transmission path 110 can be connected to the antenna and the RF transceiver, receive the RF signal output from the RF transceiver, and output the RF signal to the antenna after transmission processing, so as to transmit the RF signal through the antenna. The transmission path 110 can be provided with a power amplifier (PA), a filter, etc. to support the transmission processing of the RF signal. Accordingly, the transmission processing can be, for example, power amplification processing and filtering processing.

[0040] The number of transmission paths 110 is at least two. It can be understood that based on the current uplink multi-path transmission capability, it is mainly uplink two-path transmission. With the development of communication technology, the subsequent uplink multi-path transmission capability can be uplink three-path transmission, uplink four-path transmission, etc. The specific one can be selected according to the actual situation, and the embodiment of the present application does not make specific restrictions. At least two transmission paths 110 can support uplink multi-path transmission capability, so that the communication device can have uplink multiple input multiple output technology (UL Multiple Input Multiple Output, UL MIMO) processing function.

[0041] The processing circuit 120 may be configured to directly or indirectly obtain the channel quality environment and the communication scenario type of the communication device, and control the transmission status of each transmission path 110 based on the channel quality environment information and the communication scenario type.

[0042] Further, the channel quality environment includes a first channel quality environment and a second channel quality environment, and the second channel quality environment is better than the first channel quality environment. Optionally, the first channel quality environment can be understood as the channel quality of the environment where the communication device is located is poor, for example, the communication device is at the edge of the cell, or is in a position with much obstruction or interference with the base station, the communication device is at a long distance from the uplink transmission of the base station, and the rate is slow. The specific selection can be made according to the actual situation, and the embodiments of the present application do not make specific limitations. Optionally, the second channel quality environment can be understood as the channel quality of the environment where the communication device is located is good, for example, the communication device is in the center of the cell, or is in a position with little obstruction or interference with the base station, the uplink transmission distance between the communication device and the base station is short, and the transmission speed is fast. The specific selection can be made according to the actual situation, and the embodiments of the present application do not make specific limitations.

[0043] Furthermore, the communication scenario type refers to the scenario type in which the communication device currently needs to perform communication services. For example, the scenario types of listening to music, playing games, watching videos, etc. Optionally, the communication scenario type can be divided according to the amount of data to be transmitted, throughput requirements, latency requirements, etc. For example, the communication service scenario when the amount of data to be transmitted is greater than the preset data volume threshold is defined as the first target scenario type. Under this definition, the first target scenario type can also be understood as a scenario that requires large-scale data upload, such as ultra-high-definition live broadcasts, large-scale real-time battle games, etc. Under this communication scenario type, efficient uplink transmission performance needs to be achieved.

[0044] Furthermore, when the communication device is in a first channel quality environment, at least two transmission paths 110 are controlled to transmit radio frequency signals of the same data stream to the network device, so that at least two transmission paths 110 support transmit diversity processing, thereby enhancing the transmit power of the radio frequency signal and obtaining a higher transmit diversity gain, thereby improving the transmit performance of the communication device; when the communication device is in a second channel quality environment and the current communication scenario type is the first target scenario type, at least two transmission paths 110 are controlled to transmit radio frequency signals of different data streams to the network device, so that at least two transmission paths 110 support MIMO transmit processing, realizing independent transmission of multiple signals and doubling the rate, thereby obtaining a higher MIMO gain, improving the transmit performance of the communication device, and realizing an increase in the uplink transmission rate.

[0045] Optionally, the RF module can be applicable to RF signals of different network standards. Network standards may include GSM (Global System for Mobile Communications), UMTS (Universal Mobile Telecommunications System), LTE (Long Term Evolution) and NR (New Radio), etc. Optionally, taking the NR network standard as an example, the RF signal of the NR network standard can be called a 5G NR signal. 5G NR signals include low-frequency signals, medium-frequency signals, high-frequency signals and ultra-high-frequency signals. The frequency band division of low-frequency signals, medium-frequency signals, high-frequency signals and ultra-high-frequency signals can refer to the table below.

[0046]

[0047]

[0048] During the transmit diversity processing and MIMO transmit processing of the RF module, the multi-path transmit path 110 can simultaneously perform dual TX transmission for the RF of the above-mentioned TDD\FDD frequency band, thereby improving the uplink transmission performance of the RF module.

[0049] The radio frequency module provided in this embodiment includes at least two transmission paths 110 and a processing circuit 120. When the communication device is in a first channel quality environment, the processing circuit 120 controls at least two transmission paths 110 to transmit radio frequency signals of the same data stream, so that at least two transmission paths 110 support transmission diversity processing, thereby enhancing the transmission power of the radio frequency signal and obtaining a higher transmission diversity benefit, thereby improving the transmission performance of the communication device; when the communication device is in a second channel quality environment and the current communication scenario type is the first target scenario type, the processing circuit 120 controls at least two transmission paths 110 to transmit radio frequency signals of different data streams, so that at least two transmission paths 110 support MIMO transmission processing, thereby obtaining a higher MIMO benefit, improving the transmission performance of the communication device, and achieving an increase in the uplink transmission rate. Therefore, the radio frequency module of this embodiment can improve the uplink transmission performance of the communication device regardless of the channel quality environment, thereby improving the user experience.

[0050] In one of the embodiments, the processing circuit 120 is further configured to control at least two transmission paths 110 to transmit radio frequency signals of the same data stream at a preset power when the current communication scenario type is the second target scenario type.

[0051] Among them, the second target scenario type is a scenario where the target transmit power of each transmit path 110 is greater than the threshold, and the preset power is less than the target transmit power. In this scenario, the processing circuit 120 can control at least two transmit paths 110 to transmit RF signals of the same data stream at the preset power, and perform power superposition, thereby achieving TX enhancement based on a smaller transmit power to meet a higher power requirement.

[0052] Optionally, the second target scenario type includes a scenario in which the target transmit power is greater than the first threshold. The scenario in which the target transmit power is greater than the first threshold can be understood as a transmission scenario with a high power demand, for example, the SAN41\77\79, PC1.5 (Power Class) scenario specified in the 3GPP protocol, the PC1.5 power range is a center power of 29dBm, and the threshold is +2 / -3dBm. In this scenario, the preset power can be 26dBm. Taking the two-way transmission path 110 as an example, the processing circuit 120 can control the two-way transmission path 110 to transmit the RF signal of the same data stream at 26dBm, perform power superposition, achieve the theoretical maximum 3dB gain, and achieve TX enhancement of 26dBm+26dBm=29dBm, meet the high power demand, and improve the coverage of the communication device transmission signal. At the same time, it helps to reduce the load of a single transmission path 110 in a strong transmission state, and reduce the probability of PA burning due to high PA load. It can be understood that the high-power scenario is not limited to the scenario of high power level PC1.5 29dBm, and other power demand scenarios can also be applicable to the technical solution of this embodiment.

[0053] Optionally, the second target scenario type may also include a scenario that is greater than the second threshold and less than the first threshold. The scenario in which the target transmit power is greater than the second threshold and less than the first threshold can be understood as a transmission scenario with a small power demand. The small power demand scenario can reduce the workload of the power amplifier in each transmission path 110 to achieve the demand for low power consumption and power saving. For example, the target transmit power is 24dBm. In this scenario, the preset power can be 21dBm. Taking the two transmission paths 110 as an example, the processing circuit 120 can control the two transmission paths 110 to transmit the RF signal of the same data stream at 21dBm, perform power superposition, achieve a theoretical maximum gain of 3dB, and achieve a TX enhancement of 21dBm+21dBm=24dBm, while reducing the output power of a single PA, without reducing the signal coverage range.

[0054] In one of the embodiments, when the target channel quality environment is the second channel quality environment, the processing circuit 120 is further used to report to the network device that the communication device supports the MIMO transmission processing function, and is further used to control at least two transmission paths 110 to transmit radio frequency signals of different data streams after receiving a startup instruction fed back by the network device; the startup instruction is used to indicate that the current communication scenario type is the first target scenario type.

[0055] Among them, the processing circuit 120 controls the MIMO transmission processing of the transmission path 110, and needs to combine the scheduling of the network device to decide whether to switch. When the processing circuit 120 determines that the current target channel quality environment is the second channel quality environment, the processing circuit 120 reports to the network device that the communication device supports MIMO transmission processing capabilities, so as to ask the network device for relevant scheduling instructions. The network device will consider the current communication state of the communication device and determine the communication scenario type of the communication device with reference to CQI / SRS, etc. When the current communication scenario type is the first target scenario type, a startup instruction is generated to instruct the processing circuit 120 to execute the control of the MIMO transmission processing of the transmission path 110. After receiving the startup instruction, the processing circuit 120 determines that the communication device is in the second channel quality environment and the current communication scenario type is the first target scenario type, thereby controlling at least two transmission paths 110 to transmit radio frequency signals of different data streams, so that at least two transmission paths 110 support MIMO transmission processing.

[0056] In one embodiment, if Figure 3 As shown, the RF module also includes: multiple antennas (not shown in the figure); and multiple receiving paths 130 (four paths are shown in the figure, which is for illustration only and not limiting), each receiving path 130 can be connected to a corresponding antenna, and each receiving path 130 is used to support reception processing of RF signals from the corresponding antenna.

[0057] Among them, the receiving path 130 can be connected to the corresponding antenna to support the receiving process of the radio frequency signal received from the antenna. The receiving path 130 can be provided with a low noise amplifier, a filter, etc., and accordingly, the receiving process can include low noise amplification processing, filtering processing, etc. Optionally, the transmitting path 110 can be integrated with at least one receiving path 130 into a transceiver module, and the transmitting path 110 and the receiving path 130 can also be separated from each other. Optionally, a transmitting path 110 and a receiving path 130 can reuse the same antenna to support the transmission and reception of radio frequency signals through the antenna.

[0058] Each transmission path 110 can be switched to be connected to any one of the multiple antennas to support the transmission in turn between the multiple antennas, so that the network device receives the transmission information of each transmission path 110. The radio frequency signal transmitted in turn can be called a sounding reference signal (SRS), which is an uplink reference signal. In this embodiment, the SRS signal can be used by the network device to provide a reference for scheduling uplink resources, and can also be used by the network device to determine the signal quality environment of the communication device to generate corresponding feedback information based on the transmission information.

[0059] Furthermore, the number of receiving paths 130 may be four, and the number of transmitting paths 110 may be two, so that the RF module can support transmission in (a certain frequency band or multiple frequency bands). Figure 4 The figure shows the schematic diagram of SRS antenna transmission in rotation, which is described as follows: 1) 1T1R: The fixed antenna Ant0 feeds back information to the base station, and can only detect the channel path information corresponding to ANT0, without transmission in rotation. The channel path corresponding to the ANT1 to ANT3 antennas is not uploaded to the base station; generally refers to the NSA mode; 2) 1T4R: The terminal only supports uplink single transmission, that is, at the same time, only one ANT can be selected from the Ant0 to Ant3 antennas to transmit SRS information in turn; both NSA and SA modes are supported; 3) 2T4R: Unlike 1T4R, at the same time, two antennas can be selected from ANT0 to ANT3 to transmit SRS in turn; currently only SA mode is supported. In addition, there are other SRS modes such as 1T2R, T=R, etc. It should be noted that the R mentioned here refers to Round (meaning in turn), not Receiver (meaning receiving).

[0060] It can be understood that among the multiple antennas of the RF module, during the round-robin process, one antenna is always maintained to realize SRS communication between the communication device and the network device, so that the network device can evaluate the current signal quality environment of the communication device based on the received SRS signal to output relevant feedback information to the processing circuit 120. Optionally, the SRS signal does not carry the communication content between the user and other users, and is only used for the network device to evaluate the uplink channel quality environment of the communication device.

[0061] It can be understood that in the related art, although network devices, such as base stations, can be based on precoding matrix indicators (Precoding Matrix Indicator, PMI) (such as Figure 5 ) and SRS signals (as shown Figure 6The two different modes (as shown) detect the location of the communication device, the quality of the transmission path, etc. However, in the related art, the base station mainly allocates the downlink resources of the communication device based on the PMI and SRS signals, while in this embodiment, the base station mainly allocates the uplink resources of the communication device based on the SRS signal. Furthermore, in the SRS mode, the more antennas the RF module can participate in sending the reference signal, the more accurate the base station's estimate of the uplink channel quality environment of the communication device, and the higher the rate that can be obtained; when the number of antennas is the same, the SA mode completes the channel quality estimation faster than the NSA mode, thereby improving the network channel estimation speed. Furthermore, SRS can be used in both FDD and TDD mode base stations, wherein, in this embodiment, when used for an FDD base station, SRS can only be used to detect the uplink channel quality, and when used for a TDD base station, the detection results can be used for both uplink channel quality and downlink channel quality estimation.

[0062] The processing circuit 120 is further configured to receive feedback information output by the network device based on the round-transmission information through the receiving path 130, and determine the target channel quality environment of the communication device based on the feedback information, wherein the target channel quality environment is one of the first channel quality environment and the second channel quality environment. Thus, the feedback information received by the processing path can determine the target channel quality environment of the communication device, and then control the transmitting path 110 to switch the corresponding mode.

[0063] Optionally, the network device generates feedback information according to information including signal strength, power, etc. carried by the SRS signal, and sends the feedback information to the processing circuit 120. Thus, after receiving the feedback information, the processing circuit 120 can parse the information such as the signal strength parameter and / or the transmission power parameter corresponding to each SRS signal carried by each feedback information. When the number of parameters parsed out of the feedback information is one, the one parameter is compared with the corresponding threshold value to determine the corresponding channel quality environment; when the number of parameters parsed out of the feedback information is multiple, the multiple parameters can be clustered and / or selected to determine the corresponding signal quality environment based on the processed parameters and the related parameter thresholds. The specific selection can be made according to the actual situation, and the embodiment of the present application does not make specific limitations.

[0064] Take the case where the feedback information includes the signal strength parameter of the communication device as an example:

[0065] When the signal strength parameter does not meet the preset signal strength parameter threshold, the processing circuit 120 determines that the target channel quality environment is the first channel quality environment; when the signal strength parameter meets the preset signal strength parameter threshold, the processing circuit 120 determines that the target channel quality environment is the second channel quality environment. Thus, based on the comparison between the signal strength parameter and the preset signal strength parameter threshold, the processing circuit 120 can determine the target channel quality environment of the communication device. The preset signal strength parameter threshold can be adjusted and set according to actual needs.

[0066] Take the feedback information including the transmission power parameters of the communication device as an example:

[0067] When the transmit power parameter is greater than the preset transmit power threshold, the processing circuit 120 determines that the target channel quality environment is the first channel quality environment; when the transmit power parameter is less than or equal to the preset transmit power threshold, the processing circuit 120 determines that the target channel quality environment is the second channel quality environment. Thus, based on the comparison between the transmit power parameter and the preset transmit power threshold, the processing circuit 120 can determine the target channel quality environment of the communication device. The preset transmit power threshold can be adjusted and set according to actual needs.

[0068] It can be understood that since the communication device will move with the movement of the object carrying the communication device, the channel quality environment of the communication device will change with the different locations of the user. Therefore, the processing can control the transmission rotation of the transmission path 110 at preset time intervals, so that the network device can obtain the channel quality environment of the communication device at preset time intervals and feedback to the processing circuit 120, thereby improving the real-time control of the transmission mode of each transmission path 110 by the processing circuit 120, thereby improving the uplink transmission performance of the communication device.

[0069] In one embodiment, if Figure 7 As shown, the processing circuit 120 in any of the above embodiments includes: a radio frequency transceiver 121 and a control module 122 .

[0070] The RF transceiver 121 is connected to at least two transmission paths 110 and multiple reception paths 130 , respectively, and is used to output the RF signal to be transmitted to each transmission path 110 , and receive the RF signal output by each reception path 130 .

[0071] The control module 122 is configured to output a first control instruction to the RF transceiver 121 when the RF module is in a first channel quality environment; and to output a second control instruction to the RF transceiver 121 when the RF module is in a second channel quality environment and the current communication scenario type is a first target scenario type. The control module 122 may be, for example, a processor in a communication device.

[0072] Among them, the first control instruction is used to instruct the RF transceiver 121 to control each transmission path 110 in at least two transmission paths 110 to be connected to an antenna, and to transmit the RF signal of the same data stream to each transmission path 110, so that at least two transmission paths 110 each transmit the RF signal of the same data stream through the conductively connected antennas; the second control instruction is used to instruct the RF transceiver 121 to control each transmission path 110 in at least two transmission paths 110 to be connected to an antenna, and to transmit the RF signal of a different data stream to each transmission path 110, so that at least two transmission paths 110 each transmit the RF signal of the same data stream through the conductively connected antennas.

[0073] Therefore, the processing circuit 120 outputs corresponding control instructions to the RF transceiver 121 based on different channel quality environments, so that on the one hand, the RF transceiver 121 controls the conduction state between each transmission path 110 and the antenna, and on the other hand, the RF transceiver 121 transmits RF signals of the same data stream or RF signals of different data streams to the transmission path 110, thereby realizing the control of the transmission mode of each transmission path 110 and improving the uplink transmission performance of the RF module.

[0074] Optionally, the control module 122 may include an application processor and a baseband processor, the application processor may exchange information with the network device, and the baseband processor may be used to parse relevant parameter information. Specifically, the baseband processor may parse corresponding signal strength parameters and / or transmission power parameters and other information based on the feedback information, and send the parsed information to the application processor, which determines the channel quality environment, and then generates relevant control instructions based on the channel quality environment, the type of communication scenario, etc., and sends the relevant control instructions to the RF transceiver 121 through the baseband processor, so that the RF transceiver 121 controls the working state of the relevant devices on the transmission path 110, thereby controlling the transmission state of the transmission path 110.

[0075] In one embodiment, the radio frequency module further includes: a first switch module 140 .

[0076] The first switch module 140 is configured with a controlled end, multiple first ends and multiple second ends, the number of the first ends is the same as the number of the second ends, the controlled end is connected to the RF transceiver 121, a first end is connected to a transceiver path, the transceiver path includes a transmitting path 110 and a receiving path 130, at least another first end is correspondingly connected to at least one target path, and multiple second ends are correspondingly connected to multiple antennas, the target path includes a transmitting path 110 and / or a receiving path 130 except a transmitting path 110 and a receiving path 130, and the first switch module 140 is used to switchably select and conduct the connection between the transceiver path, the target path and the multiple antennas respectively.

[0077] Among them, the first end is connected to the transceiver path, and the transceiver path includes a transmitting path 110 and a receiving path 130 respectively connected to the first end, so that the first end can be multiplexed as a transceiver end (hereinafter referred to as the transceiver end in this embodiment) to support the transmission and reception of radio frequency signals, and the transceiver path is used to support the transceiver processing of radio frequency signals.

[0078] Among them, multiple first ends of the first switch module 140 are respectively connected to the transceiver path and at least another target path, the target path includes a transmitting path 110 and / or a receiving path 130 other than a transmitting path 110 and a receiving path 130, and multiple second ends are respectively connected to multiple antennas.

The third receiving path 130 and the fourth receiving path 130 are separated into a receiving module 1 and a receiving module 2, respectively. Further optionally, as Figure 8 As shown (the number of ports connecting the transceiver module, the receiving module and the RF transceiver 121 in the figure is only an example, and the number can be adjusted according to actual needs), the first switch module 140 may include a first switch and a second switch (the connection between the switch and the RF transceiver 121 is not shown in the figure), the transceiver module 1 and the receiving module 1 are respectively switchably connected to two antennas (such as ANT1 and ANT2 in the figure) through the first switch, and the transceiver module 2 and the receiving module 2 are respectively switchably connected to two antennas through the second switch, thereby realizing the 2T4R\TX diversity\UL MIMO function, which is applicable to the RF module solution of any of the above embodiments.

[0081] Optionally, the multi-channel transmission path 110 includes a first transmission path 110 and a second transmission path 110, and the multi-channel receiving path 130 includes a first receiving path 130, a second receiving path 130, a third receiving path 130 and a fourth receiving path 130.

Further optionally, as Fig.10 As shown, the first switch module 140 may include a fourth switch and a fifth switch, and the transceiver module 3 and the receiving module 3 may be multiplexed, with two-stream receiving capability (for example, DRX / MIMO2 reception is performed by the receiving module 3, and PRX / MIMO1 is performed by the transceiver module 3). Thus, the architecture of this embodiment may also realize 2T4R, TX diversity, and UL MIMO. Further optionally, as Fig.11 As shown, the first switch module 140 may include a sixth switch, the transceiver module has a switch inside, and is configured with two antenna ports to be connected to two antennas (such as ANT1 and ANT2 in the figure), respectively, and has a path to allow the signal to pass through it to the receiving module 3. The receiving module 3 and the transceiver module 3 both have a two-stream receiving capability in a certain frequency band, on the one hand, downlink 4*4 MIMO and receive diversity enhancement can be realized, on the other hand, the transmitting module 1 can switchably conduct and connect the two antennas (such as ANT3 and ANT4 in the figure), so that the architecture of this embodiment can also realize 2T4R and TX diversity, UL MIMO.

[0082] It can be understood that the above embodiments only illustrate some embodiments, and there are other more architectures applicable to the technical solutions of the present application, which will not be introduced one by one in the embodiments of the present application.

[0083] In one embodiment, if Fig.12As shown (three transmission paths 110 are used as an example in the figure), the number of transmission paths 110 can be greater than three; the RF transceiver 121 is configured with at least two transmission ends, and one transmission end can be switched to connect two transmission paths 110; thus, one of the at least two transmission ends can be multiplexed to connect to the two transmission paths 110. Optionally, the one transmission end can be switched to connect the two transmission paths 110 through the second switch module 150.

[0084] Among them, optionally, when the two transmission paths 110 are in the first channel quality environment and the frequency band of the RF signal output by a transmitting end is the TDD frequency band, the first control instruction is also used to instruct the RF transceiver 121 to control the connection between the two transmission paths 110 and a transmitting end to be alternately turned on, so that the two transmission paths 110 transmit the RF signal of the same data stream to the network device. It can be understood that the duty cycle of the alternating conduction can correspond to the duty cycle of TDD, so that when the two transmission paths 110 of the same transmitting end are alternately turned on, each turn-on can receive the RF signal of the same data stream transmitted by the RF transceiver 121, and no data loss will be caused. In a sense, it can be equivalent to the two transmission paths 110 of the same transmitting end being turned on at the same time, so that one transmitting end can achieve two-way transmission diversity enhancement. Optionally, the TDD frequency band can include, for example, frequency bands such as N41 / 77 / 78 / 79. Furthermore, each of the at least two transmitting ends except one transmitting end can be connected to the corresponding transmitting path 110 to achieve at least another transmitting diversity enhancement. Therefore, the RF module of this embodiment can achieve at least 3TX simultaneous transmission, which is stronger than 2TX transmission and has a wider coverage range.

[0085] Among them, optionally, when the two transmission paths 110 are in the first channel quality environment and the frequency band of the RF signal output by a transmitting end is the FDD frequency band, the first control instruction is also used to instruct the RF transceiver 121 to control the connection between one of the two transmission paths 110 and the transmitting end to transmit the RF signal. Thus, the RF module of this embodiment can at least realize 2TX simultaneous transmission, thereby improving the coverage range of the RF module.

[0086] Optionally, please refer to Fig.12 Other transmitting paths 110 and receiving paths 130 can be integrated into a transceiver module 5, a receiving module 4, etc., and the switching of multiple antennas can be achieved through the first switch module 140. The relevant embodiments of the switching of multiple antennas can refer to the relevant introduction of the above embodiments, which will not be repeated here.

[0087] In one of the embodiments, at least two antennas in the above embodiment can be respectively arranged on different frames of the communication device. When at least two transmission paths 110 support transmission diversity processing, the processing circuit 120 is further configured to determine the target antennas corresponding to the at least two transmission paths 110 based on the signal quality information of each antenna, and control the at least two transmission paths 110 to be connected to the corresponding target antennas to transmit radio frequency signals. This can make the selectivity of the antenna used for transmission diversity more flexible, and can select an antenna with higher antenna efficiency to transmit radio frequency signals, thereby achieving high-power transmission.

[0088] For example, please refer to Fig.12 and Fig.13 Antenna ANT5 is located on the side frame of the communication device. When the device is held in landscape mode (for gaming, video, and other scenarios) or held with one hand, due to the existence of SAR (specific absorption rate), the antenna held by the human hand cannot transmit the maximum power, and there will be targeted power fallback. However, antenna ANT5 on the side frame will not be held or blocked, and some specific frequency bands can be transferred to antenna ANT5 to achieve high-power transmission.

[0089] Further optionally, the processing circuit 120 may obtain network information based on the RF signals respectively measured by multiple antennas based on the RF signals currently transmitted by at least one antenna, and determine the target antenna based on the multiple network information. For example, the RF transceiver 121 may control the connection between each antenna and each receiving path 130 in sequence to make each antenna in a working state, and then correspondingly measure the network information of the RF signal received by each antenna. The network information may include original and processed information associated with the wireless performance metrics of the received radio frequency signal, such as received power, transmit power, reference signal received power (RSRP), reference signal received quality (RSRQ), received signal strength indicator (RSSI), signal to noise ratio (SNR), rank of the MIMO channel matrix, carrier to interference plus noise ratio (RS-CINR), frame error rate, bit error rate, channel quality environment measurement based on signal quality data (such as Ec / lo or c / No data), etc. Exemplarily, in the embodiment of the present application, the network information is taken as the reference signal received power as an example for explanation. That is, the radio frequency module can obtain multiple reference signal received powers corresponding to multiple receiving antennas, and obtain the maximum value of the multiple reference signal received powers, so as to use the maximum value as the target network information, and the antenna corresponding to the target network information is the target antenna.

[0090] The present application also provides a radio frequency processing method, which is applied to a communication device, such as Fig.14 As shown, it includes: step 142 and step 144.

[0091] Step 142: When the communication device is in a first channel quality environment, control at least two transmission paths to transmit radio frequency signals of the same data stream, so that the at least two transmission paths support transmit diversity processing.

[0092] Step 144, when the communication device is in the second channel quality environment and the current communication scenario type is the first target scenario type, control at least two transmission paths to transmit radio frequency signals of different data streams, so that at least two transmission paths support MIMO transmission processing.

[0093] Each transmission path is used to support transmission processing of a radio frequency signal to be transmitted; and the second channel quality environment is better than the first channel quality environment.

[0098] Among them, multiple receiving paths can be connected to multiple antennas respectively, and each receiving path is used to support the reception and processing of radio frequency signals from the corresponding antenna; each transmitting path can be switchably connected to any one of the multiple antennas to support alternating transmission between the multiple antennas, so that the network device receives the transmission information of each transmitting path.
