For example, the network currently accessed by the electronic device is a 5G network, and theoretically, for example, 28GHz (gigahertz), the available spectrum bandwidth can reach 1 GHz. In practice, the bandwidth of the signal that can be transmitted in the network may be 40MHz (megahertz), 80MHz or higher, such as 400 MHz.

step 202: determining a transceiver circuit matched with the first parameter;
here, the first transceiver circuit and the second transceiver circuit are provided in advance in the electronic apparatus. The bandwidth of the signal to be transmitted which is transmitted and received by the first transceiver circuit is higher than the bandwidth of the signal to be transmitted which is transmitted and received by the second transceiver circuit. I.e. the first transceiver circuit is more suitable for transmission of higher bandwidth signals than the second transceiver circuit. In this embodiment, the transceiver circuit for receiving and transmitting the signal to be transmitted in a segmented manner is at least the first transceiver circuit.
In technical implementation, bandwidth characteristics of a signal to be transmitted, such as the size of a bandwidth, are used to decide which transceiver circuit is enabled. Specifically, the following scheme is adopted to determine which transceiver circuit is currently adopted:

The first transceiver circuit comprises M channel circuits, wherein M is a positive integer greater than or equal to 2.
Here, a first predetermined threshold and a second predetermined threshold are preset, and whether the first transceiver circuit or the second transceiver circuit is enabled is determined by a magnitude relation between a bandwidth of a signal to be transmitted and the first predetermined threshold and the second predetermined threshold. Wherein the first predetermined threshold is greater than or equal to the second predetermined threshold. That is, in the first transceiver circuit and the second transceiver circuit, the first transceiver circuit is more suitable for transmission of large bandwidth signals.
The first predetermined threshold may be 40MHz or 80MHz, the second predetermined threshold may be 40MHz or 20MHz, and any other reasonable value may be taken, which is not specifically limited.
If the transceiver circuit matching the first parameter is determined to be the first transceiver circuit in step 202, the following process is executed:

step 204: and controlling N channel circuits in the M channel circuits to be started, wherein N is a positive integer and is less than or equal to M, and the started N channel circuits are used for receiving and transmitting the at least two sub-signals.
The main body for executing steps 201-204 is an electronic device. For the understanding of steps 201 and 202, please refer to the description of steps 101 and 102, which is not described herein. Step 202 and step 203 may also be performed simultaneously without strict sequencing.

That is, the first transceiver circuit can transmit signals with a large bandwidth, and the first transceiver circuit can be used to transmit and receive 5G signals, wherein the 5G signals are transmitted and received in a segmented manner. Further, 5G signals are transmitted, the transmission function of the electronic equipment is enhanced, and the usability of the electronic equipment is highlighted.
And transmitting the signals to be transmitted in a segmented manner in the first transceiver circuit, and opening all channel circuits or opening part of the channel circuits. In a specific implementation, the number of the channel circuits that are turned on in the M channel circuits in the first transceiver circuit at least matches the number of the divided sub-signals, that is, the number N of the turned-on channel circuits is the same as the number of the sub-signals divided by the signal to be transmitted, and the turned-on N channel circuits are used to transmit and receive corresponding sub-signals in each sub-signal, that is, each channel circuit realizes the transmission and reception of one of the sub-signals. Therefore, the started N channel circuits can realize the transceiving of the whole signal to be transmitted. Therefore, the high-bandwidth signals can be successfully transmitted and received, the 5G signals can be successfully transmitted and received, and the transmission function of the electronic equipment on the 5G signals can be further improved.
It can be understood that: the channel circuit in the first transceiver circuit can perform certain processing on the sub-signals which are responsible for transceiving. In a specific implementation, each channel circuit at least includes: a first device for filtering processing and a second device for mixing processing. On one channel circuit, the first device is used for filtering the sub-signals, the second device is used for mixing the sub-signals to obtain target sub-signals, and then the target sub-signals obtained by processing the sub-signals through the channel circuits are gathered to obtain target signals, wherein the target signals are signals expected to be received or sent by local electronic equipment. Thus, smooth transmission or reception of signals to be transmitted, such as 5G signals, can be achieved.
The following describes the technical solution of the embodiment of the present application in detail with reference to the circuit structure shown in fig. 3.
In the circuit configuration shown in fig. 3, the following is included: an antenna, a switch R (multiple throw switch), switches 1A, 2a … MA (first set of switches), M mixers, switches 1B, 2B … MB (second set of switches), M duplexers (or filters), and a transceiver.
The switches 1A and 2a … MA each have two operating states, and taking switch 1A (one of the first set of switches) as an example, the first operating state is when switch 1A is turned to position 1, and the second operating state is when switch 1A is turned to position 2. The switches 1B, 2B … MB have two operating states, for example, switch 1B (one of the second set of switches) which is the first operating state when switch 1B is actuated to position 3 and the second operating state when switch 1B is actuated to position 4. When the switches 1A, 2a … MA and the switches 1B, 2B … MB are both in the first operating state, the circuit configuration shown in fig. 3 is a first transceiver circuit (as shown in solid line portions). Each of the channel circuits in the first transceiving circuit includes: one of the switches in the first set of switches, a mixer, one of the switches in the second set of switches, and a filter. When the switches 1A and 2a … MA and the switches 1B and 2B … MB are in the second operating state, the circuit configuration shown in fig. 3 is a second transceiver circuit (shown by a dotted line).
In the circuit structure shown in fig. 3, the multi-throw switch R is used to transmit a signal received from an antenna to which channel circuit, or to process and assemble signals to be transmitted by an electronic device into a signal desired to be transmitted through each channel circuit and transmit the signal through the antenna.
The electronic equipment reads the bandwidth of a signal to be transmitted, and the bandwidth of the signal received by the electronic equipment, specifically an antenna, is assumed to be 400MHz and is a 5G ultra-bandwidth signal; the signal to be transmitted by the electronic device is a 5G signal with a bandwidth of 120 MHz. If the bandwidths of the two signals are greater than the first predetermined threshold value of 80MHz, the transceiver circuit to be activated by the electronic device is the first transceiver circuit. When the electronic device controls each switch in the first set of switches to be in the first operating state, and each switch in the second set of switches to be in the first operating state, the circuit structure shown in fig. 3 is the first transceiver circuit (as shown by the solid line). The following describes the signal receiving flow and the signal transmitting flow of the first transceiver circuit, respectively:
a receiving process:
aiming at a 400MHz ultra-wideband signal received by an antenna, the ultra-wideband signal is segmented and divided to obtain at least two sub-signals. Suppose that the sub-signal 1 is 40MHz, the sub-signal 2 is 60MHz, the sub-signal 3 is 60MHz, the sub-signal N is 60MHz, etc. The number of enabled channel circuits in the first transceiving circuit is the same as the number N of divided sub-signals.
The individual sub-signals are fed to the individual channel circuits by means of a multi-throw switch R. For example, sub-signal 1 is sent into channel circuit 1, sub-signal 2 is sent into channel circuit 2, sub-signal 3 is sent into channel circuit 3, and so on.
In the channel circuit 1, the switch 1A and the switch 1B both operate in the first operating state, and the sub-signal 1 is mixed with the mixer to obtain a signal with a center frequency of f 1. Where f1 ═ f (maximum received frequency of filter 1) -demodulation bandwidth + 400/2; assuming that the receiving frequency of the filter is 2110MHz-2170MHz, the maximum receiving frequency is 2170MHz, and the demodulation bandwidth is 40MHz, f1 is 2170-40+200 is 2330MHz, and after filtering by the filter 1, a signal (target sub-signal 1) with the frequency of 2150MHz and the bandwidth of 40MHz is formed, and the target sub-signal 1 is sent to the transceiver for demodulation.
In the channel circuit 2, both the switch 2A and the switch 2B operate in the first operating state, the sub-signal 2 and the mixer 2 are mixed to obtain a signal with a center frequency of f2, according to the above calculation formula, f2 is 1990-20+400/2 is 2370MHz, the signal with the center frequency of f2 is filtered by the filter 2 to obtain a signal (target sub-signal 2) with a frequency of 1980MHz and a bandwidth of 20MHz, and the target sub-signal 2 is sent to the transceiver for demodulation. Wherein, the receiving frequency of the filter 2 is 1930-.
In the channel circuit 3, both the switch 3A and the switch 3B operate in the first operating state, the sub-signal 3 and the mixer 3 are mixed to obtain a signal with a center frequency of f3, according to the above calculation formula, f3 is 2690-60+400/2 is 2830MHz, the signal with the center frequency of f3 is filtered by the filter 3 to obtain a signal (target sub-signal 3) with a frequency of 2660MHz and a bandwidth of 60MHz, and the target sub-signal 3 is sent to the transceiver for demodulation. Wherein the receiving frequency of the filter 3 is 2496-2690 MHz.
And repeating the steps until the last sub-signal, such as the sub-signal N, is processed by the mixer N and the filter N to obtain the target sub-signal N, and sending the target sub-signal N to the transceiver for demodulation.
A sending process:
assume that the signal to be transmitted by the electronic device is a 5G signal with a frequency of 3600MHz and a bandwidth of 120 MHz. Considering that the bandwidth is large, the electronic device segments the signal to be transmitted to obtain N ═ 3 sub-signals, for example, sub-signal 1 whose frequency range is 3540 and 3580MHz bandwidth is 40 MHz; sub-signal 2, whose frequency range is 3580 and 3600MHz and bandwidth is 20MHz signal; the sub-signal 3 has a frequency range of 3600 and 3660MHz and a bandwidth of 60 MHz.
The sub-signal 1 is sent from the transceiver to the filter 1, and after filtering processing by the filter 1, a signal with the central frequency of 1950MHz and the bandwidth of 40MHz is obtained, and after the signal is mixed by the mixer 1, the signal becomes a signal (target sub-signal 1) with the central frequency f1 being 3560MHz (5510MHz-1950M) and the bandwidth of 40MHz, and is sent to the multi-throw switch R. Wherein the frequency of the mixer is assumed to be 5510 HZ.
The sub-signal 2 is sent from the transceiver to the filter 2, and after filtering processing by the filter 2, a signal with a center frequency of 1880MHz and a bandwidth of 20MHz is obtained, and after being mixed by the mixer 2, the signal becomes a signal (target sub-signal 2) with a center frequency f1 being 3590MHz (5470MHz-1880MHz) and a bandwidth of 40MHz, and is sent to the multi-throw switch R. Wherein the frequency of the mixer is assumed to be 5470 MHz.
The sub-signal 3 is sent from the transceiver to the filter 3, and after filtering processing by the filter 3, a signal with the center frequency of 2600MHz and the bandwidth of 60MHz is obtained, and after frequency mixing by the mixer 3, the signal becomes a signal (target sub-signal 3) with the center frequency f1 being 3630MHz (6230MHz-2600MHz) and the bandwidth of 60MHz, and is sent to the multi-throw switch R. Wherein the frequency of the mixer is assumed to be 6230 MHz.
The signal transmitted from the antenna is a 5G signal having a frequency bandwidth of 3540MHz to 3660MHz, and the signal is a signal obtained by combining the target sub-signals 1 and 2 and the target sub-signal 3, and the signal is a signal desired to be transmitted. Wherein 3540MHz is 3560MHz-40 MHz/2; 3660MHz is 3630MHz +60 MHz/2.
In the above scheme, the number of the enabled channel circuits is the same as the number of the divided sub-signals, and in design, the number of the channel circuits is set according to the maximum transmission capability of the network, so as to avoid the problem that part of the sub-signals cannot be transmitted due to insufficient number of the channel circuits. In practical application, the electronic device selects how many channel circuits need to be enabled at the same time according to the bandwidth of the signal to be transmitted, so that the attenuation of the energy of signal transmission caused by opening unnecessary channel circuits can be avoided.
In the above scheme, segmented transmission of a signal with a higher bandwidth, namely a 5G signal, can be realized, processing of each sub-signal is realized through a channel circuit to obtain a target sub-signal, and the target sub-signal is demodulated or an expected signal obtained by collecting the target sub-signals is transmitted. And further realize the transmission of 5G signals.
The above scheme is explained by using 5G signals with large bandwidth of signals to be transmitted. And if the electronic equipment reads the bandwidth of the signal to be transmitted, wherein the bandwidth is less than a second preset threshold value of 20MHz, the transceiver circuit to be started by the electronic equipment is a second transceiver circuit. As shown by the dotted line in fig. 3, in the second transceiver circuit, considering that the bandwidth of the signal to be transmitted is small, the signal to be transmitted does not need to be segmented, and only one of the M channel circuits, for example, the channel circuit 1 where the switches 1A and 1B are located, needs to be used to transmit or receive the signal to be transmitted. This process is not described in detail, and for the same reference is made to the above description of the 5G signal.
