Description
Technical Field
The application belongs to the technical field of electronic equipment, and particularly relates to a radio frequency circuit, a radio frequency circuit control method, a radio frequency circuit control device and electronic equipment.
Background
With the rise of the fifth generation mobile communication technology (5G), the frequency band of 5G is gradually increased, and now the frequency bands of N41, N77, N78, N79, etc. are primarily divided, and the frequency ranges of NR (new air interface) N79 and WIFI (mobile hot spot) 5G are listed in table 1, and the frequency intervals of the two are 150 MHz. The frequencies of the two are very close and it is difficult to provide sufficient out-of-band rejection by adding filters in the transmit or receive path. When N79 and WiFi5G are operating simultaneously, the receive path may be severely interfered due to insufficient antenna isolation and out-of-band rejection of the rf path.
| Systems of | Frequency band | Uplink frequency range | Downlink frequency range | Duplex system |
| NR | N79 | 4400-5000GHz | 4400-5000GHz | TDD |
| WIFI | 5G | 5150-5850MHz | 5150-5850MHz | TDD |
Table 13 GPP N79 and WIFI5G frequency band planning
Specifically, as mobile phones are increasingly lighter and thinner, the space is limited, more and more antennas are provided, the distance between the antennas is limited, and the isolation is limited; therefore, when the coexistence scene occurs in the N79 and the WIFI5G, the receiving paths of the two parties are seriously interfered, so that desensitization is caused, and even the LNA (low noise amplifier) module is completely blocked or damaged due to too high coupling power. The coexistence of N79 and WIFI5G is one of the current industry challenges.
At present, there are two main solutions to solve the above problems:
1. scheme one, TDM (time division multiplexing) mechanism: by configuring the working time slot ratio, the working time of the two is staggered, and coexistence interference is avoided;
2. scheme two, the mutual exclusion mechanism: a cutting mode is adopted, if the N79 is high in priority, N79 communication is reserved, and WIFI5G is turned off; conversely, WIFI5G is retained and N79 is turned off.
However, these two schemes have the following problems:
1. although the TDM mechanism can enable WIFI5G and N79 to communicate simultaneously, the throughput rate is positively correlated with the configured time slot, and the evaluation reduction of the throughput rate and the configured time slot is about 50%; secondly, the 5G NR time slot is too short, the time slot switching is difficult to realize together with the WIFI5G, the requirement on software control is higher and more complex, and a better effect is not realized at present.
2. The mutual exclusion mechanism is a cutting mode, and although communication of one party with high priority is not influenced, the other party cannot communicate at all, so that user experience is influenced.
Therefore, the existing radio frequency circuit schemes aiming at WIFI5G and N79 have the problems of high implementation difficulty, poor performance and the like.

In this embodiment of the application, the controlling of the double-pole double-throw switch in the radio frequency circuit to turn on the first radio frequency module and the third antenna in the radio frequency circuit, and to turn on the second radio frequency module and the first antenna in the radio frequency circuit specifically includes: and controlling the first input end and the second output end of the double-pole double-throw switch to be communicated so as to conduct the first radio frequency module and the third antenna in the radio frequency circuit, and controlling the second input end and the first output end of the double-pole double-throw switch to be communicated so as to be communicated with the second radio frequency module and the first antenna in the radio frequency circuit.

Therefore, the complete function of the antenna can be guaranteed, the insertion loss of one switch is only increased when the first radio frequency transceiver and the second radio frequency transceiver are communicated with the third antenna when the two parties work independently, the receiving performance is reduced slightly, and the signal loss is reduced as much as possible.
In this embodiment of the application, the controlling the double-pole double-throw switch to turn on the first radio frequency module and the first antenna in the radio frequency circuit, and turn on the second radio frequency module and the third antenna in the radio frequency circuit specifically includes: and controlling a first input end and a first output end of the double-pole double-throw switch to be communicated so as to conduct a first radio frequency module and a first antenna in the radio frequency circuit, and controlling a second input end and a second output end of the double-pole double-throw switch to be communicated so as to conduct a second radio frequency module and a third antenna in the radio frequency circuit.
The radio frequency circuit and the radio frequency circuit control method provided in the embodiments of the present application are further described below, in which the first radio frequency transceiver takes a WIFI5G frequency band radio frequency transceiver as an example; the second RF transceiver is exemplified by an N79 band RF transceiver; the first antenna is called antenna 1, the second antenna is called antenna 2, the third antenna is called antenna 3, the fourth antenna is called antenna 4 and the fifth antenna is called antenna 5.
In view of the foregoing technical problems, an embodiment of the present application provides a radio frequency circuit and a radio frequency circuit control method, where: on hardware, a double-pole double-throw switch (DPDT) is added on a WIFI5G transmitting and receiving path (TRX, namely a path of a first radio frequency transceiver and a first radio frequency module) and an N79 auxiliary receiving path (namely a path of a second radio frequency transceiver and a second radio frequency module), and switching is realized through the switch. When WIFI5G and N79 coexist, a WIFI5G TRX channel is switched to a preset antenna with a longer distance, and antenna isolation degree which is much larger than that in a default state is provided, so that the purpose of reducing mutual interference and improving performance during coexistence is achieved; when the WIFI5G and N79 auxiliary receiving paths work independently, the insertion loss of one switch is increased, and the receiving performance is reduced slightly. The hardware inhibition capability is improved by increasing the antenna isolation through the switching path to ensure that the throughput rate reduction degree is minimum when the two devices communicate simultaneously, and compared with a TDM mechanism, the performance reduction is about 50 percent and a mutual exclusion mechanism, the performance improvement effect is better. Specifically, the method comprises the following steps:
as for the rf circuit, the scheme can be specifically divided into three parts as shown in fig. 3 (in the figure, a represents LNA, b represents PA, c represents filter, d represents DPDT, PRX represents primary set reception, DRX represents diversity reception, and MIMO represents multi-input and multi-output): the first part is a WIFI5G TRX part (corresponding to the first radio frequency transceiver and the first radio frequency module), and comprises a WIFI chip (corresponding to the WIFI5G frequency band radio frequency transceiver), a transmitting and receiving module (corresponding to the first radio frequency module and comprising a Power Amplifier (PA), a Low Noise Amplifier (LNA), a switching unit and a filter), and an antenna (corresponding to the first antenna); the second part is a part of N79 TRX, N79 DRX and N79 PRX (corresponding to the first radio frequency transceiver, the second radio frequency module, the third radio frequency module, the fourth radio frequency module and the fifth radio frequency module), and comprises a 5G chip (corresponding to the N79 frequency band radio frequency transceiver), a transmitting and receiving module (corresponding to the third radio frequency module), a receiving module (corresponding to the second radio frequency module, the fourth radio frequency module and the fifth radio frequency module; including a low noise amplifier LNA and a filter), and an antenna (corresponding to the second antenna, the third antenna, the fourth antenna and the fifth antenna); the third part is an added double pole double throw switch DPDT. In this description, the power detection, power supply, and the like are not shown.
In the embodiment of the present application, the layout positions of the antennas may be as shown in fig. 4, and it is assumed that the antennas 3, 4, and 5 can cover WIFI5G and N79 frequency bands; wherein:
presetting the isolation between the antenna 2 and the antenna 1 to be 15 dB;
presetting the isolation between the antenna 2 and the antenna 3 to be 40 dB;
presetting the isolation between the antenna 2 and the antenna 4 to be 25 dB;
the antenna 2 and antenna 5 isolation is preset to 20 dB.
In this scheme, DPDT may be added to the WIFI5G TRX path (i.e., the path of antenna 1) and the path of antenna 3 with the greatest isolation from antenna 2; if there are other antennas with larger isolation in the actual design, DPDT may be added to other antennas (e.g. antennas 4 and/or 5) according to the actual situation, and the principle may be to add to the antenna path with the largest isolation from antenna 2.
The radio frequency circuit control scheme based on the radio frequency circuit can be realized as follows:
1. when WIFI5G and N79 work alone, WIFI5G and N79 respectively and independently go through default preset paths (both are respectively connected), as shown in fig. 5 (in the figure, a indicates LNA, b indicates PA, c indicates filter, d indicates DPDT, PRX indicates main set reception, DRX indicates diversity reception, and MIMO indicates multi-input multi-output), WIFI5G TRX may go through a path through which antenna 1 and a WIFI chip are connected, N79 TRX may go through a path through which antenna 2 is connected, and N79 DRX may go through a path through which antenna 3 is connected to the 5G chip; WIFI5G and N79 work independently without interfering with each other; compared with the conventional scheme, the WIFI5G only increases the insertion loss of one switch, and the performance influence is small;
2. when WIFI5G and N79 work simultaneously in a coexistence scenario, the DPDT switch may be switched (specifically, the controller of the electronic device may send a signal to the DPDT to control the DPDT to switch), as shown in fig. 6 (in the drawing, a represents an LNA, b represents a PA, c represents a filter, d represents a DPDT, PRX represents main set reception, DRX represents diversity reception, and MIMO represents multiple input and multiple output), WIFI5G TRX switches from the antenna 1 path to the antenna 3 path (i.e., turns off the antenna 1 and the WIFI chip, and connects the antenna 3 and the WIFI chip to serve as WIFI5G TRX); the N79 DRX path switches from antenna 3 to antenna 1 path (i.e., turns off antenna 3 and 5G chips, turns on antenna 1 and 5G chips to serve as N79 DRX); n79 TRX is still the path of the original antenna 2;
under the preset condition, the isolation between the antenna 2 and the antenna 1 is 15dB in the default state; the distance between the antenna 2 and the antenna 3 is relatively long, and the isolation is 40 dB; in a coexistence scene, the WIFI5G is switched from the antenna 1 to the antenna 3, and theoretically, the antenna isolation can be increased by 25dB, so that the performance can be improved by 25dB (theoretical situation) compared with the original state in the coexistence scene;
according to practical test research, if the link isolation can achieve 60dB (including a link suppression degree and antenna isolation), the mutual interference of the N79 and the WIFI5G can be controlled within 3 dB; as the antenna 2 and the antenna 3 are far away from each other, the isolation can be 40dB or higher, and then the filter suppression degree in the link needs 20dB to satisfy the total suppression of 60dB, so that the interference when WIFI5G and N79 coexist is within 3dB, and the performance is greatly improved compared with the TDM mechanism.
Therefore, the mutual interference problem under the scene of coexistence (simultaneous working) of WIFI5G and 5G N79 can be solved, whether WIFI5G and 5G N79 coexist or not is mainly judged, a WIFI5G TRX channel is switched to a preset far 5G N79 built-in receiving antenna during coexistence, and the isolation of the two antennas is increased by increasing the distance between the WIFI5G antenna and the 5G N79 antenna, so that the problem of coexistence interference of WIFI5G and 5G N79 is solved.
In the embodiment of the application, under the condition that a first radio frequency transceiver and a second radio frequency transceiver in a radio frequency circuit work, a double-pole double-throw switch in the radio frequency circuit is controlled to conduct a first radio frequency module and a third antenna in the radio frequency circuit and conduct a second radio frequency module and a first antenna in the radio frequency circuit; the access of the first radio frequency transceiver can be switched to a preset antenna with a longer distance when the first radio frequency transceiver and the second radio frequency transceiver work together, and the antenna isolation degree which is much larger than that in the default state is provided, so that the purpose of reducing mutual interference and improving performance when the first radio frequency transceiver and the second radio frequency transceiver coexist is achieved; therefore, the scheme can improve the hardware inhibition capability by switching the path to increase the antenna isolation degree, so as to ensure that the throughput rate is reduced to the minimum degree when the two devices communicate simultaneously and ensure the realization performance; the realization difficulty is low; the problems of high difficulty and poor performance of radio frequency circuit schemes comprising different radio frequency transceivers are well solved, and the problems of high difficulty and poor performance of the radio frequency circuit schemes aiming at WIFI5G and N79 in the prior art are also solved.
It should be noted that, in the radio frequency circuit control method provided in the embodiment of the present application, the execution main body may be a radio frequency circuit control device, or a control module in the radio frequency circuit control device for executing the radio frequency circuit control method. In the embodiment of the present application, a method for executing a radio frequency circuit control by a radio frequency circuit control device is taken as an example to describe the radio frequency circuit control device provided in the embodiment of the present application.
An embodiment of the present application further provides a radio frequency circuit control apparatus, which is applied to the electronic device described above, as shown in fig. 7, the apparatus includes:
the first control module 71 is configured to control a double-pole double-throw switch in the radio frequency circuit to turn on a first radio frequency module and a third antenna in the radio frequency circuit, and turn on a second radio frequency module and a first antenna in the radio frequency circuit when it is determined that both the first radio frequency transceiver and the second radio frequency transceiver in the radio frequency circuit are working.
