Exemplary embodiments of the present invention will be described below in further detail with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention may be implemented in various forms without being limited to the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

As shown in <FIG>, an embodiment of the present invention provides a network radio frequency apparatus, applied to an electronic device and including:.

In this embodiment, the first radio frequency module <NUM> may be a long term evolution (Long Term Evolution, LTE) radio frequency module. It should be noted that the first transmitting module <NUM> is a transmitting module that satisfies the transmitting functions of the LTE signal frequency band and the <NUM> signal frequency band (such as the N41 frequency band). The first receiving module <NUM> is a receiving module that satisfies receiving functions of the LTE signal frequency band and the <NUM> signal frequency band.

As shown in <FIG>, for example, the first transmitting module <NUM> is an LTE transmitting module and the first receiving module <NUM> is an LTE receiving module. The LTE transmitting module is connected to a first interface K1 of the first DPDT switch <NUM>, and the LTE receiving module is connected to a second interface K2 of the first DPDT switch <NUM>. A first contact a1 of the first DPDT switch <NUM> is connected to the first antenna ANT1, and a second contact a2 of the first DPDT switch <NUM> is connected to the second antenna ANT2. A signal sent by the radio frequency transceiver <NUM> can pass through the LTE transmitting module and the first DPDT switch <NUM> and is sent though ANT1 and ANT2.

The second radio frequency module <NUM> may be an NR radio frequency module. The signal sent by the radio frequency transceiver <NUM> can pass through the second radio frequency module <NUM> (that is, the NR radio frequency module) and the first switch unit <NUM>, and is sent to the base station through the third antenna ANT3 and the fourth antenna ANT4.

It should be noted that during signal transmission, for example, a signal sent by the radio frequency transceiver <NUM> is a sounding reference signal (Sounding Reference Signal, SRS). Standalone and non-standalone NR bands need to support a technology of 2T4R (<NUM> channels of transmissions and <NUM> channels of reception) or 1T4R (<NUM> channel of transmission and <NUM> channels of reception) that transmits SRSs by turns through antennas. 2T4R of SRS signals includes two channels of SRS signals. Because 2T4R of SRS signals includes two channels of SRS signals, optionally, a first channel of SRS signal passes through the first radio frequency module <NUM> (that is, the LTE radio frequency module) and the first DPDT switch <NUM>, and is sent through ANT1 and ANT2. A second channel of SRS signal passes through the second radio frequency module <NUM> (that is, the NR radio frequency module) and the first switch unit <NUM>, and is sent through ANT3 and ANT4. In this way, the network radio frequency apparatus implements 2T4R of SRS signals.

Optionally, for 2T4R of SRS signals, the two channels of SRS signals can also be sent through the second radio frequency module <NUM> (that is, the NR radio frequency module), that is, the second radio frequency module <NUM> sends the two channels of SRS signals through different antennas respectively by using the first switch unit <NUM>.

1T4R of an SRS signal only needs to send one channel of SRS signal. Therefore, the SRS signal can pass through the second radio frequency module <NUM> and the first switch unit <NUM>, and is sent through ANT3 and ANT4 and the other two antennas. Alternatively, the SRS signal passes through the first radio frequency module <NUM> and the first DPDT switch <NUM>, and is sent through the ANT1 and ANT2. In addition, the SRS signal passes through the second radio frequency module <NUM> and the first switch unit <NUM> and is sent through the ANT3 and ANT4. It should be noted that the SRS signal needs to be transmitted through the first radio frequency module <NUM> and the second radio frequency module <NUM> at a preset time sequence. In this way, the network radio frequency apparatus implements 1T4R of an SRS signal.

Certainly, the first radio frequency module and the second radio frequency module in this embodiment may also be radio frequency modules in bands other than <NUM> LTE and <NUM> NR bands, which is not specifically limited in this embodiment.

The embodiments of the present invention simplify the network radio frequency apparatus, use a DPDT switch and a switch unit to replace a 3P3T switch or a DP4T switch in the prior art, reduce switch insertion losses, and therefore improve the sensitivity of the radio frequency apparatus. In addition, switch logic is simple and the layout is flexible. At the same time, the SRS function and the antenna switching function of the network radio frequency apparatus can be performed.

Specific structural forms of the second radio frequency module <NUM> and the first switch unit <NUM> are described below with specific embodiments.

In form <NUM>, as shown in <FIG>, optionally, the first switch unit <NUM> includes: a second DPDT switch <NUM>.

The second radio frequency module <NUM> includes: a second transmitting module <NUM> and a second receiving module <NUM>, the second transmitting module <NUM> is connected to a first interface of the second DPDT switch <NUM>; and the second receiving module <NUM> is connected to a second interface of the second DPDT switch <NUM>.

For example, the second radio frequency module <NUM> is an NR radio frequency module, the second transmitting module <NUM> may be an NR transmitting module, and the second receiving module <NUM> may be an NR receiving module. As shown in <FIG>, the NR transmitting module is connected to the first interface L1 of the second DPDT switch <NUM>, the first contact b1 of the second DPDT switch <NUM> is connected to the third antenna ANT3, the NR receiving module is connected to the second interface L2 of the second DPDT switch <NUM>, and the second contact b2 of the second DPDT switch <NUM> is connected to the fourth antenna ANT4. A signal sent by the radio frequency transceiver <NUM> passes through the NR transmitting module and the second DPDT switch <NUM> and is sent though ANT3 and ANT4.

As shown in <FIG>, 2T4R of SRS signals includes two channels of SRS signals, a first channel of SRS signal passes through the first transmitting module <NUM> and the first DPDT switch <NUM>, and is sent through ANT1 and ANT2. A second channel of SRS signal passes through the NR transmitting module and the second DPDT switch <NUM>, and is sent through ANT3 and ANT4. In this way, the network radio frequency apparatus implements 2T4R of SRS signals. It should be noted that the first transmitting module <NUM> and the NR radio frequency module need to work simultaneously for the first channel of SRS signal and the second channel of SRS signal, that is, while the first transmitting module <NUM> transmits the first channel of SRS signal, the NR radio frequency module transmits the second channel of SRS signal.

For 1T4R of an SRS signal, the SRS signals need to be sent at a preset time sequence. Optionally, as shown in <FIG>, through the NR transmitting module and the switching of the second DPDT switch <NUM>, the SRS signal is transmitted to ANT3 and ANT4 and is sent through ANT3 and ANT4; transmission of an SRS signal by the NR radio frequency module is stopped; and through the first transmitting module <NUM> and the switching of the first DPDT switch <NUM>, the SRS signal is transmitted to ANT1 and ANT2 and sent through ANT1 and ANT2. In this way, the network radio frequency apparatus implements the 1T4R function of an SRS signal in general.

In this embodiment, the first switch unit is set as a DPDT switch, and an externally connected <NUM> transmitting module and two DPDT switches may be configured to perform 2T4R and 1T4R functions of SRS signals, which effectively reduces the number of radio frequency amplifier components, channel switches, and antennas, thereby reducing costs. Compared with the 3P3T switch or the DP4T switch in the prior art, switch insertion losses are reduced, thereby improving sensitivity of the radio frequency apparatus. This can greatly improve the overall performance of the network radio frequency apparatus.

In form <NUM>, as shown in <FIG>, optionally, the first switch unit <NUM> includes:
a DP4T switch <NUM>; a first single pole double throw (single pole double throw, SPDT) switch <NUM> connected to a first contact of the DP4T switch <NUM>, where the first SPDT switch <NUM> is connected to the third antenna; and a second SPDT switch <NUM> connected to a fourth contact of the DP4T switch <NUM>, where the second SPDT switch <NUM> is connected to a sixth antenna; where a second contact of the DP4T switch <NUM> is connected to the fourth antenna, and a third contact of the DP4T switch <NUM> is connected to the fifth antenna.

Further, the second radio frequency module <NUM> includes: a first transmitting submodule <NUM>, connected to the first interface of the DP4T switch <NUM>; a second transmitting submodule <NUM>, connected to a second interface of the DP4T switch <NUM>; a first multiple-input multiple-output (MIMO) module <NUM>, connected to the first SPDT switch <NUM>; and a second MIMO module <NUM>, connected to the second SPDT switch <NUM>.

As shown in <FIG>, the first transmitting submodule <NUM> is connected to the first interface M1 of the DP4T switch <NUM>, and the second transmitting submodule <NUM> is connected to the second interface M2 of the DP4T switch <NUM>. The first contact c1 of the DP4T switch <NUM> is connected to the first contact d1 of the first SPDT switch <NUM>, and the interface of the first SPDT switch <NUM> is connected to ANT3. The second contact c2 of the DP4T switch <NUM> is connected to ANT4, and the third contact c3 of the DP4T switch <NUM> is connected to ANT5. The fourth contact c4 of the DP4T switch <NUM> is connected to the first contact e1 of the second SPDT switch <NUM>, and the interface of the second SPDT switch <NUM> is connected to ANT6. The first MIMO module <NUM> is connected to the second contact d2 of the first SPDT switch <NUM>, and the second MIMO module <NUM> is connected to the second contact e2 of the second SPDT switch <NUM>.

The second radio frequency module <NUM> may be an NR radio frequency module, the first transmitting submodule <NUM> may be a first NR transmitting module, the second transmitting submodule <NUM> may be a second NR transmitting module, the first MIMO module <NUM> may be a first NR MIMO module, and the second MIMO module <NUM> may be a second NR MIMO module.

As shown in <FIG>, for 2T4R of SRS signals, the first channel of SRS signal passes through the first transmitting submodule <NUM> and the DP4T switch <NUM>, is transmitted to ANT3 through the first SPDT switch <NUM>, is transmitted to ANT4 through the second contact of the DP4T switch <NUM>, and is sent by ANT3 and ANT4. The second channel of SRS signal passes through the second transmitting submodule <NUM> and the DP4T switch <NUM>, is transmitted to ANT6 through the second SPDT switch <NUM>, is transmitted to ANT5 through the third contact of the DP4T switch <NUM>, and is sent by ANT5 and ANT6. In this way, the network radio frequency apparatus implements the 2T4R function of SRS signals.

As shown in <FIG>, for 1T4R of SRS signals, through the second transmitting submodule <NUM> and the switching of the DP4T switch <NUM>, the SRS signal passes through the first SPDT switch <NUM> and the second SPDT switch <NUM>, and is transmitted to ANT3, ANT4, ANT5, and ANT6. In this way, the network radio frequency apparatus implements the 1T4R function of an SRS signal.

In this embodiment, the first switch unit is set as a apparatus of a DP4T switch and two SPDT switches to replace a 3P3T switch or a DP4T switch in the prior art, to reduce switch insertion losses, and therefore improve the sensitivity of the radio frequency apparatus. In addition, switch logic is simple and the layout is flexible. At the same time, the SRS function and the antenna switching function of the network radio frequency apparatus can be performed.

An embodiment of the present invention further provides an electronic device, including the foregoing network radio frequency apparatus. A person skilled in the art may understand that, the electronic device may be a mobile phone, and may also be applied to another electronic device that has a display screen, such as a tablet computer, an e-book reader, a moving picture experts group audio layer III (Moving Picture Experts Group Audio Layer III, MP3) player, a moving picture experts group audio layer IV (Moving Picture Experts Group Audio Layer IV, MP4) player, a laptop computer, a vehicle-mounted computer, a desktop computer, a set top box, a smart television, and a wearable device that all fall within the protection scope of the embodiments of the present invention.

As shown in <FIG>, an embodiment of the present invention further provides a radio frequency control method, applied to an electronic device. The electronic device includes a first radio frequency module and a second radio frequency module, and the method includes the following steps.

Step <NUM>: Control the first radio frequency module and the second radio frequency module to transmit a first signal and a second signal respectively; where the first radio frequency module transmits the first signal through a first antenna and a second antenna, and the second radio frequency module transmits the second signal through a third antenna and a fourth antenna; or control the second radio frequency module to transmit the first signal and the second signal.

The first signal and the second signal may be a same signal or different signals. The first radio frequency module may be an LTE radio frequency module, and the second radio frequency module may be an NR radio frequency module.

During signal transmission of the electronic device, standalone and non-standalone NR bands need to support a technology of 2T4R (<NUM> channels of transmissions and <NUM> channels of reception) or 1T4R (<NUM> channel of transmission and <NUM> channels of reception) that transmits SRSs by turns through antennas. Since 2T4R of SRS signals includes two channels of SRS signals, a first signal and a second signal are signals of a same type with different transmission channels. Optionally, the first channel of SRS signal (that is, the first signal) is transmitted by the first radio frequency module through the first antenna and the second antenna, and the second channel of SRS signal (that is, the second signal) is transmitted by the second radio frequency module through the third antenna and the fourth antenna; or the two channels of SRS signals are both transmitted by the second radio frequency module, so that 2T4R of SRS signals is implemented.

For 1T4R of SRS signals, since only one channel of SRS signal needs to be sent, when the second radio frequency module is controlled to transmit the first signal and the second signal, the first signal and the second signal are a same signal. The SRS signal may be sent by the second radio frequency module through multiple antennas; or the SRS signal may be sent by the first radio frequency module through the first antenna and the second antenna, and the SRS signal is sent by the second radio frequency module through the third antenna and the fourth antenna. It should be noted that the transmission of the SRS signal by the first radio frequency module and the second radio frequency module needs to be performed in a preset time sequence. In this way, 1T4R of an SRS signal is implemented.

In the embodiments of the present invention, signals are transmitted in multiple modes, and network radio frequency sensitivity of the electronic device is improved. Besides, in the method, the electronic device can perform 2T4R and 1T4R functions of SRS signals.

Optionally, the controlling the first radio frequency module and the second radio frequency module to transmit the first signal and the second signal respectively includes:
controlling the first radio frequency module and the second radio frequency module to transmit the first signal and the second signal respectively at a first moment; or controlling the first radio frequency module and the second radio frequency module to transmit, according to a preset time sequence, the first signal and the second signal respectively.

That the first radio frequency module and the second radio frequency module transmit the first signal and the second signal respectively at the first moment means: while the first radio frequency module transmits the first signal, the second radio frequency module transmits the second signal.

For 2T4R of SRS signals, for example, the first signal is the first channel of SRS signal and the second signal is the second channel of SRS signal. As shown in <FIG>, the first radio frequency module sends the first channel of SRS signal to the first antenna and the second antenna, and the first channel of SRS signal is sent by the first antenna and the second antenna; and the second radio frequency module sends the second channel of SRS signal to the third antenna and the fourth antenna, and the second channel of SRS signal is sent by the third antenna and the fourth antenna. In addition, the first radio frequency module and the second radio frequency module send the first channel of SRS signal and the second channel of SRS signal at the same moment, so that 2T4R of the SRS signals is implemented.

For 1T4R of an SRS signal, SRS signals need to be sent at a preset time sequence. Further, the controlling the first radio frequency module and the second radio frequency module to transmit, according to a preset time sequence, the first signal and the second signal respectively specifically includes:
controlling the second radio frequency module to transmit the second signal; and after the second radio frequency module transmits the second signal, controlling the first radio frequency module to transmit the first signal.

For 1T4R of an SRS signal, for example, the first signal is the first channel of SRS signal and the second signal is the second channel of SRS signal. As shown in <FIG>, although two transmitting modules are configured to perform the 1T4R function of a signal, in this solution, one transmitting module (that is, the second radio frequency module) is configured to transmit the second signal to the third antenna and the fourth antenna, and then this channel of transmission needs to be stopped, and the other transmitting module (that is, the first radio frequency module) is configured to transmit the first signal to the first antenna and the second antenna, thereby implementing the 1T4R function of the SRS signal in general.

Optionally, the second radio frequency module includes the first transmitting submodule and the second transmitting submodule, and the controlling the second radio frequency module to transmit the first signal and the second signal includes:
controlling the first transmitting submodule and the second transmitting submodule to transmit a first signal and a second signal respectively; where the first transmitting submodule transmits the first signal through a third antenna and a fourth antenna, and the second transmitting submodule transmits the second signal through a fifth antenna and a sixth antenna.

For example, the first signal is the first channel of SRS signal and the second signal is the second channel of SRS signal. As shown in <FIG>, the first transmitting submodule sends the first channel of SRS signal to the third antenna and the fourth antenna, and the first channel of SRS signal is sent by the third antenna and the fourth antenna; and the second transmitting submodule sends the second channel of SRS signal to the fifth antenna and the sixth antenna, and the second channel of SRS signal is sent by the fifth antenna and the sixth antenna. In this way, the two channels of SRS signals are both transmitted by the second radio frequency module, to implement the 2T4R function of SRS signals.

Optionally, the second radio frequency module includes the first transmitting submodule and the second transmitting submodule, and the controlling the second radio frequency module to transmit the first signal and the second signal includes:
controlling the second transmitting submodule to transmit the first signal and the second signal; where the second transmitting submodule transmits the first signal through the third antenna and the fourth antenna, and transmits the second signal through the fifth antenna and the sixth antenna.

In this embodiment, the first signal and the second signal are a same signal. For example, the signal is an SRS signal. This solution is applicable to 1T4R of an SRS signal, that is, only one transmitting module is required to transmit the SRS signal. As shown in <FIG>, the second transmitting submodule sends the SRS signal to the third antenna, the fourth antenna, the fifth antenna, and the sixth antenna, where a signal sent by the third antenna and the fourth antenna is considered to be the first signal, and a signal sent by the fifth antenna and the sixth antenna is considered to be the second signal. It should be noted that for 1T4R of the SRS signal, the first signal and the second signal are a same signal.

In the embodiments of the present invention, signals are transmitted in multiple modes, and network radio frequency sensitivity of the electronic device is improved. An externally connected <NUM> transmitting module can be configured to perform the 2T4R and 1T4R functions of the SRS signals, effectively reducing the costs.
