Description

Frequency band processing method and electronic equipment

Technical Field

The present invention relates to the field of computer technologies, and in particular, to a frequency band processing method and an electronic device.

Background

In order to ensure smooth transition and forward compatibility of communication systems, currently, international and domestic mainstream operators plan to adopt a network architecture of Non-independent Networking (NSA) in the first stage. The NSA architecture requires the terminal to perform EN _ DC (uplink _ NR Dual Connection, Long Term Evolution (LTE)/New Radio (NR) Dual Connection), that is, uplink simultaneous transmission. In an EN _ DC context, an LTE eNB serves as a primary base station, a 5G gbb serves as a secondary base station, a terminal performs signaling interaction with an Evolved Packet Core (EPC) through the LTE eNB, the 5G gbb only provides a data plane bearer, and the terminal may have a dual-connection scenario in which LTE and NR transmit and receive simultaneously.

In order to support large-scale antenna technology (Massive MIMO), an electronic device will carry more antennas, and under the condition that the size of the electronic device is fixed, as the number of antennas increases, the distance between the antennas becomes closer and closer, resulting in that the isolation between an LTE intermediate frequency antenna and an NR high frequency antenna and a Global Positioning System (GPS) antenna becomes lower and lower, and the power of a GPS channel leaking signals transmitted in an LTE frequency band and an NR frequency band becomes higher. One problem that has to be faced in this case is that the coexistence of transmitting signals in the LTE band and the NR band simultaneously and receiving signals in the GPS band causes in-band interference, which deteriorates the GPS positioning and tracking performance and seriously affects the consumer experience. For example, when LTE B1 and NR n78 transmit signals simultaneously in EN _ DC scene, after the transmitted signals are coupled to the antenna of the L1 path of GPS through respective antennas, an intermodulation signal is generated and introduced into the usable signal band of the L1 path of GPS, causing in-band interference, causing degradation of GPS positioning and tracking performance, and seriously affecting the consumer experience.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a flowchart of a frequency band processing method according to an embodiment of the present invention. The frequency band processing method shown in fig. 1 is applied to an electronic device, and the electronic device includes: a first antenna module and a second antenna module, the second antenna module comprising at least two global positioning system, GPS, antennas, the method comprising the steps of:

s102, under the condition that the electronic equipment is monitored to work in the first frequency band and the second frequency band simultaneously, the carrier-to-noise ratio corresponding to the GPS antenna which transmits signals based on the third frequency band in the second antenna module is determined.

It should be noted that the carrier-to-noise ratio is a standard measurement scale used to mark the relationship between the carrier and the carrier-to-noise; a high carrier to noise ratio may provide better network acceptance, better network communication quality, and better network reliability.

In implementation, the first frequency band and the second frequency band may be frequency bands corresponding to two different communication networks, where the different communication networks may be, for example, an LTE communication network and a 5G communication network under an NSA architecture, and if the electronic device operates in the first frequency band and the second frequency band simultaneously, it indicates that the electronic device may perform data transmission through the communication network corresponding to the first frequency band, and may also perform data transmission through the communication network corresponding to the second frequency band. In the process of data transmission of the electronic device through a communication network corresponding to a certain frequency band, a large number of antennas may be required, and a GPS antenna for positioning may be further disposed in the electronic device, so that the size of the electronic device is generally small, and therefore, the antennas in the electronic device may be distributed densely, which may cause a phenomenon that isolation between the antennas is generally low, so that signals may interfere with each other, and therefore, the antennas of the communication network and the GPS antenna need to be isolated, specifically, when it is monitored that the electronic device performs data transmission through the communication network corresponding to the first frequency band and performs data transmission through another communication network corresponding to the second frequency band, it may be determined that the electronic device simultaneously operates in the first frequency band and the second frequency band, and at this time, a carrier-to-noise ratio corresponding to the GPS antenna for transmitting signals based on a certain frequency band (i.e., a third frequency band) in the second antenna module may be obtained, the carrier-to-noise ratio may be measured by a corresponding instrument, or a corresponding parameter may be measured by some instrument, and then the carrier-to-noise ratio may be calculated from the measured parameter.

S104, when the carrier-to-noise ratio is smaller than a preset threshold value and a first GPS antenna based on a third frequency band transmission signal exists in the second antenna module, so that the first isolation degree of the first GPS antenna relative to the first antenna module is smaller than the second isolation degree of other GPS antennas relative to the first antenna module, interchanging the frequency bands of the second GPS antennas in the other GPS antennas and the first GPS antenna; and the difference value between the frequency band used by the second GPS antenna and the third frequency band is in a preset numerical range.

The predetermined range of values may be determined based on the frequency band to be interchanged being different from the third frequency band, at least not equal to or not close to the third frequency band.

In the implementation, when the electronic device is monitored to perform data transmission through the communication network corresponding to the first frequency band and simultaneously perform data transmission through the other communication network corresponding to the second frequency band, the magnitude relationship between the carrier-to-noise ratio corresponding to the GPS antenna transmitting signals in the third frequency band in the second antenna module and the preset threshold may be compared, if the carrier-to-noise ratio is smaller than the preset threshold value, the first GPS antenna based on the third frequency band transmission signal is determined to exist in the second antenna module, such that a first isolation of the first GPS antenna relative to the first antenna module is less than a second isolation of the other GPS antennas relative to the first antenna module, a first preset command may be transmitted to a Modem through an AP (Application Processor), and receiving the first preset instruction through the Modem, and executing the GPS RX switch matrix to interchange the frequency bands of the second GPS antenna and the first GPS antenna in other GPS antennas. In this way, the first GPS antenna for transmitting signals in the third frequency band is switched to the second GPS antenna with a high isolation, so that electromagnetic interference of the cross-modulation signals of the communication network corresponding to the first frequency band and the communication network corresponding to the second frequency band to the GPS based on the signals transmitted in the third frequency band is reduced without increasing the antenna path loss corresponding to the frequency band.

As can be seen from the above technical solutions provided by the embodiments of the present invention, in the embodiments of the present invention, an electronic device includes: a first antenna module and a second antenna module, the second antenna module comprising at least two global positioning system, GPS, antennas, the method comprising: under the condition that the electronic equipment is monitored to work in a first frequency band and a second frequency band simultaneously, determining a carrier-to-noise ratio corresponding to a GPS antenna based on a third frequency band transmission signal in a second antenna module; and when the carrier-to-noise ratio is smaller than a preset threshold value and the second antenna module is provided with a first GPS antenna based on a third frequency band transmission signal, so that the first isolation degree of the first GPS antenna relative to the first antenna module is smaller than the second isolation degree of other GPS antennas relative to the first antenna module, interchanging the frequency bands of the second GPS antennas in other GPS antennas and the first GPS antenna. The method is equivalent to switching the third frequency band to the antenna frequency band with high isolation, so that the interference of signals transmitted by the first frequency band and the second frequency band simultaneously to signals received in the GPS frequency band is reduced under the condition of not increasing the antenna path loss corresponding to the frequency bands, the positioning accuracy and speed of the dual-frequency GPS are ensured, and the use experience of a user is improved.

In an embodiment of the present invention, the determining of the frequency band used by the second GPS antenna as the fourth frequency band further includes, before the exchanging the frequency bands of the second GPS antenna and the first GPS antenna in the other GPS antennas in the step S104:

the method comprises the steps of firstly, determining the antenna state of a second antenna module, wherein the antenna state comprises a first state and a second state.

And step two, when the antenna state is the first state, determining that the first isolation degree is smaller than the second isolation degree.

The first state means that the first GPS antenna transmits signals through a third frequency band, the second GPS antenna transmits signals through a fourth frequency band, the second state means that the second GPS antenna transmits signals through the third frequency band, the first GPS antenna transmits signals through the fourth frequency band, and the isolation degree of the first GPS antenna relative to the first antenna module is smaller than that of the second GPS antenna relative to the first antenna module.

In this embodiment, whether the first isolation of the GPS antenna transmitting signals in the third frequency band with respect to the first antenna module is smaller than the second isolation of the GPS antenna transmitting signals in the fourth frequency band with respect to the first antenna module can be determined by using the antenna state of the second antenna module, which is convenient for determining the relative magnitude of the isolation between the GPS antenna transmitting signals in the third frequency band and the GPS antenna transmitting signals in the fourth frequency band.

Fig. 2 is a schematic diagram of a partial architecture of an electronic device according to an embodiment of the present invention. As shown in fig. 2, the electronic apparatus includes: a first GPS antenna 21, a first filter 22, a first low noise amplifier 23, a GPS receiving module 27, a GPS baseband module 28 and a processing module 29, a second GPS antenna 24, a second filter 25, a second low noise amplifier 26. The first GPS antenna 21 is connected to the first filter 22, the first filter 22 is connected to the first low noise amplifier 23, the first low noise amplifier 23 is connected to the GPS receiving module 27, the second GPS antenna 24 is connected to the second filter 25, the second filter 25 is connected to the second low noise amplifier 26, and the second low noise amplifier 26 is connected to the GPS receiving module 27. The GPS receiving module 27 is connected to the baseband module 28, and the baseband module 28 is connected to the processing module 29. Then, the third frequency band may refer to a frequency band in which signals are transmitted through the path (or path) formed by the first GPS antenna 21 via the first filter 22, the first low noise amplifier 23 and the GPS receiving module 27, and the fourth frequency band may refer to a frequency band in which signals are transmitted through the path (or path) formed by the second GPS antenna 24 via the second filter 25, the second low noise amplifier 26 and the GPS receiving module 27.

In one embodiment of the present invention, a first antenna module includes: an intermediate frequency antenna and a high frequency antenna. The above electronic device further includes: and the radio frequency transceiving module. The channel between the intermediate frequency antenna and the radio frequency transceiver module works in a first frequency band, and the channel between the high frequency antenna and the radio frequency transceiver module works in a second frequency band. It will be appreciated by those skilled in the art that signals in a first frequency band are transmitted via an intermediate frequency antenna and signals in a second frequency band are transmitted via a high frequency antenna. Through the embodiment, under the condition that the antenna path loss corresponding to the frequency band is not increased, the interference of signals transmitted in the high-frequency band and the intermediate-frequency band to signals received in the GPS frequency band is reduced under the condition that the electronic equipment works in the high-frequency band and the intermediate-frequency band at the same time, the positioning accuracy and the speed of the dual-frequency GPS are ensured, and the consumer experience is improved.

Specifically, the if antenna may be a 4G (i.e., LTE) antenna, and the hf antenna may be a 5G (i.e., NR) antenna. Through the embodiment, under the condition that the antenna path loss corresponding to the frequency band is not increased, the interference of signals received in the GPS frequency band can be reduced when the 4G antenna and the 5G antenna of the electronic equipment transmit simultaneously, the positioning accuracy and the speed of the dual-frequency GPS are ensured, and the consumer experience is improved.

Specifically, the first frequency band may be an LTE frequency band, and the second frequency band may be an NR frequency band. Through the embodiment, under the condition that the antenna path loss corresponding to the frequency band is not increased, the interference of signals transmitted in the LTE frequency band and the NR frequency band to signals received in the GPS frequency band is reduced under the condition that the electronic equipment works in the LTE frequency band and the NR frequency band at the same time, the positioning accuracy and the speed of the dual-frequency GPS are ensured, and the consumer experience is improved.

In an embodiment of the present invention, the third central frequency of the third frequency band is greater than the fourth central frequency of the fourth frequency band. Through the embodiment, under the condition that the antenna path loss corresponding to the frequency band is not increased, the interference of the signals transmitted by the first frequency band and the second frequency band simultaneously to the main frequency band receiving signals with relatively large central frequency in the dual-frequency GPS is reduced, the positioning precision and the speed of the dual-frequency GPS are ensured, and the consumer experience is improved.

Taking an NSA architecture as an example, in the NSA architecture, through a mechanism of dual connection between LTE and 5G, downlink data plane can be transmitted based on LTE and 5G paths, so as to meet the requirement of high rate, but control plane data of a 5G communication network is transmitted based on the LTE path, that is, transmission is performed along a spectrum (700MHz-2700MHz) of a medium-low frequency band of LTE, so as to ensure uplink coverage performance and stability of network connection. The mechanism defines a series of frequency band combinations, such as B1/B3 of LTE and n77/n78 of 5G, B8 of LTE and n78/n79 of 5G, B41 of LTE and n41 of 5G, and the like. Specifically, the first frequency band may be a B1 frequency band of LTE, and the second frequency band may be a 5G n78 frequency band.

Specifically, fig. 3 is a perspective view of an electronic device provided by an embodiment of the invention. As shown in fig. 3, the electronic apparatus includes: the antenna system comprises a first antenna module 31 and a second antenna module 32, wherein the second antenna module 32 comprises a first GPS antenna 321 and a second GPS antenna 322, wherein the isolation degree of the first GPS antenna 321 relative to the first antenna module 31 is smaller than the isolation degree of the second GPS antenna 322 relative to the first antenna module 31. The frequency band of the transmission signal between the first GPS antenna 321 and the GPS receiving module may be a third frequency band, and the frequency band of the transmission signal between the second GPS antenna 322 and the GPS receiving module may be a fourth frequency band.

In implementation, first, when it is monitored that the electronic device does not simultaneously operate in the B1 frequency band of LTE and the n78 frequency band of 5G, an initial carrier-to-noise ratio corresponding to the first GPS antenna 321 transmitting signals based on the third frequency band (e.g., the L1 frequency band 1575.42MHz ± 1.023MHz) is determined and denoted as a. When it is monitored that the electronic device simultaneously operates in the B1 frequency band of LTE and the n78 frequency band of 5G, a carrier-to-noise ratio corresponding to the first GPS antenna 321 based on a signal transmitted in a third frequency band (e.g., the L1 frequency band 1575.42MHz ± 1.023MHz) is determined, and is denoted as B.

Then, it is determined whether the carrier-to-noise ratio is smaller than a preset threshold, where the determination process may be implemented by determining whether a performance degradation degree a-b of the carrier-to-noise ratio of the third frequency band is greater than a threshold a, and at this time, it may also be determined whether a carrier-to-noise ratio b of the third frequency band is smaller than a preset threshold (a-a), where the preset threshold is (a-a).

Specifically, when it is monitored that the electronic device simultaneously operates in the B1 frequency band of LTE and the n78 frequency band of 5G, if it is determined that the carrier-to-noise ratio B corresponding to the first GPS antenna transmitting signals based on the third frequency band (e.g., the L1 frequency band 1575.42MHz ± 1.023MHz) is smaller than the preset threshold (a-a), the first preset instruction may be sent to the Modem by an AP (Application Processor), the first preset instruction may be received by the Modem, and the GPS RX switch matrix is executed to interchange the second GPS antenna 322 frequency band (e.g., the L5 frequency band 1176.45MHz ± 1.023MHz) with the first GPS antenna frequency band (e.g., the L1 frequency band 1575.42MHz ± 1.023 MHz). In this way, the first GPS antenna 321 for transmitting signals in the third frequency band is switched to the frequency band used by the second GPS antenna 322 with high isolation, so that electromagnetic interference caused by the LTE and NR intermodulation signals to GPS signals transmitted in the third frequency band is reduced without increasing the antenna path loss corresponding to the frequency band.
