In the embodiment of the application, a first signal to noise ratio of a first radio frequency signal is acquired in a process that a first antenna of electronic equipment receives the first radio frequency signal and the first antenna transmits a second radio frequency signal, and whether the first signal to noise ratio is within a signal to noise ratio threshold value is judged, if the electronic equipment determines that the first signal to noise ratio is not within the signal to noise ratio threshold value, the electronic equipment determines that the quality of the first radio frequency signal currently received does not meet a quality condition, adjusts the transmitting power of the second radio frequency signal to obtain reduced transmitting power, and finally, receives the first radio frequency signal with constant receiving power through the first antenna and transmits the second radio frequency signal with reduced transmitting power through one antenna selected from the first antenna and the second antenna of the electronic equipment, thereby reducing noise generated by the second radio frequency signal on the first radio frequency signal and improving the first signal to noise ratio.
The signal transmission method provided by the embodiment of the application comprises the steps of obtaining a first signal-to-noise ratio of a first radio frequency signal through a first antenna of electronic equipment in the process of receiving the first radio frequency signal and transmitting a second radio frequency signal by the first antenna, wherein an overlapping part exists between the receiving frequency range of the first radio frequency signal and the transmitting frequency range of the second radio frequency signal, if the first signal-to-noise ratio is not in the signal-to-noise ratio threshold range, receiving the first radio frequency signal by the first antenna at constant receiving power, and transmitting the second radio frequency signal by the first antenna and one antenna selected from the second antenna of the electronic equipment at reduced transmitting power, wherein the reduced transmitting power is used for reducing noise generated by the second radio frequency signal to the first radio frequency signal to improve the first signal-to-noise ratio, and therefore, the signal-to-noise ratio of the second radio frequency signal to the first radio frequency signal is reduced, and the receiving performance of the first radio frequency signal is improved.
The embodiment of the application provides a signal transmission method, which is applied to electronic equipment, and is shown in fig. 2, and the method comprises the following steps 201 to 202, or step 201, and step 203 to step 205:
step 201, a first signal-to-noise ratio of a first radio frequency signal is obtained in a process that the first antenna of the electronic device receives the first radio frequency signal and the first antenna transmits a second radio frequency signal.
Wherein, there is an overlapping portion between the receiving frequency range of the first radio frequency signal and the transmitting frequency range of the second radio frequency signal.
Step 202, if the first signal-to-noise ratio is not within the signal-to-noise ratio threshold, switching one of the first radio frequency signal and the second radio frequency signal transmitted by the first antenna to the second antenna with a distance greater than or equal to the distance threshold.
In the embodiment of the present application, the distance threshold may be understood as that the distance between the first antenna and the second antenna satisfies the distance condition. Here, the distance between the first antenna and the second antenna being equal to or greater than the distance threshold value may be understood as that the second radio frequency signal transmitted through the second antenna does not generate noise to the first radio frequency signal received through the first antenna or generates noise to the first radio frequency signal within an acceptable range.
In the embodiment of the application, the electronic equipment receives the first radio frequency signal through the first antenna, and in the process of transmitting the second radio frequency signal through the first antenna, acquires the first signal-to-noise ratio of the first radio frequency signal, judges whether the first signal-to-noise ratio is within the signal-to-noise ratio threshold range, if the electronic equipment determines that the first signal-to-noise ratio is not within the signal-to-noise ratio threshold range, the electronic equipment determines that the quality of the currently received first radio frequency signal does not meet the quality condition, further, the electronic equipment can switch the first radio frequency signal received through the first antenna to the second antenna with the distance from the first antenna being greater than or equal to the distance threshold to receive the first radio frequency signal, and certainly, the electronic equipment can also switch the second radio frequency signal transmitted through the first antenna to the second antenna with the distance from the first antenna being greater than or equal to the distance threshold to transmit the second radio frequency signal, so that when the second antenna with the distance from the first antenna meeting the distance requirement is transmitted the second radio frequency signal, the influence on the first radio frequency signal received through the first antenna is slowed down, so that the signal-to improve the signal-to-noise ratio of the first radio frequency signal received through the first radio frequency signal, and further improve the receiving performance of the first radio frequency signal.
Step 203, if the first snr is not within the snr threshold, switching the second rf signal transmitted by the first antenna to be transmitted by a second antenna having a distance from the first antenna smaller than the distance threshold.
In the embodiment of the present application, the distance between the first antenna and the second antenna being smaller than the distance threshold value may be understood that the second radio frequency signal transmitted by the second antenna may generate a certain noise for the first radio frequency signal received by the first antenna, and the noise generated for the first radio frequency signal is within an unacceptable range. When the electronic device transmits the second radio frequency signal through the second antenna having a distance from the first antenna smaller than the distance threshold, the noise generated on the first radio frequency signal received through the first antenna is necessarily smaller than when the electronic device transmits the second radio frequency signal and receives the first radio frequency signal on the same antenna, that is, on the first antenna, the noise generated on the first radio frequency signal received through the first antenna is necessarily smaller than when the electronic device transmits the second radio frequency signal and receives the first radio frequency signal on the same antenna.
In the embodiment of the application, the electronic equipment receives the first radio frequency signal through the first antenna, acquires the first signal-to-noise ratio of the first radio frequency signal in the process of transmitting the second radio frequency signal through the first antenna, judges whether the first signal-to-noise ratio is within the signal-to-noise ratio threshold value range, determines that the quality of the currently received first radio frequency signal does not meet the quality condition if the signal-to-noise ratio is not within the signal-to-noise ratio threshold value range, and further can switch the second radio frequency signal transmitted through the first antenna to be transmitted through the second antenna with the distance smaller than the distance threshold value from the first antenna.
Step 204, obtaining a second signal-to-noise ratio of the first radio frequency signal.
Step 205, if the second snr is not within the snr threshold, receiving the first rf signal at a constant receiving power by the first antenna, and transmitting the second rf signal at a reduced transmitting power by the second antenna.
In the embodiment of the application, the electronic equipment determines that the first signal to noise ratio is not in the signal to noise ratio threshold range, switches the second radio frequency signal transmitted by the first antenna to the second radio frequency signal transmitted by the second antenna with the distance smaller than the distance threshold value, continuously acquires the second signal to noise ratio of the first radio frequency signal at the current moment, judges whether the second signal to noise ratio is in the signal to noise ratio threshold range, if the electronic equipment determines that the second signal to noise ratio is not in the signal to noise ratio threshold range, the electronic equipment determines that the quality of the first radio frequency signal received currently still does not meet the quality condition, adjusts the transmitting power of the second radio frequency signal to obtain the reduced transmitting power, and finally receives the first radio frequency signal with constant receiving power through the first antenna and continuously transmits the second radio frequency signal with reduced transmitting power through the second antenna, thereby reducing the noise generated by the second radio frequency signal to the first radio frequency signal, improving the first signal to noise ratio under the condition that the second radio frequency signal still affects the first radio frequency signal received through the first antenna is transmitted by the second antenna with the distance smaller than the distance threshold value.
In one possible application scenario, referring to fig. 3, fig. 3 shows a schematic structure of an Antenna, taking NR Band numbers NR Band 5 and NR Band 8 supported by an electronic device as an example, before the electronic device switches antennas (Antenna, ANT), the electronic device may receive and transmit a second radio frequency signal in an operating Band corresponding to NR Band 8 through a first Antenna ANT1, receive a first radio frequency signal in an operating Band corresponding to NR Band 5 through a third Antenna ANT0, and have no overlapping portion between an uplink Band corresponding to NR Band 5 and a downlink Band corresponding to NR Band 8, so that Antenna switching is not required. The first antenna is a device of a main set receiving path (PRIMARY RECEIVER CHAIN, PRX) in a Low frequency Band (LB), the third antenna is a device of a diversity receiving path (DIVERSITY RECEIVER CHAIN, DRX) in the Low frequency Band LB, and the second antenna is a device of another main set receiving path PRX in the Low frequency Band LB.
When the electronic device needs to transmit the second radio frequency signal with the frequency in the working frequency Band corresponding to NR Band 8 through the first antenna, there may be a case that the first antenna of the electronic device receives the first radio frequency signal and the first antenna transmits the second radio frequency signal, and because there is an overlapping portion between the downlink frequency Band corresponding to NR Band 5 and the uplink frequency Band corresponding to NR Band 8, the electronic device needs to switch the antennas. According to the embodiment of the application, the electronic equipment switches the antennas, namely, receives the first radio frequency signal at constant receiving power through the first antenna, and transmits the second radio frequency signal at reduced transmitting power through a selected one of the first antenna and the second antenna of the electronic equipment. After the electronic device performs antenna switching, the first antenna is a device of a main set receiving path PRX in the low frequency Band LB, and the first antenna is used for receiving a first radio frequency signal in an operating Band corresponding to the NR Band 5, the third antenna is a device of a diversity receiving path DRX in the low frequency Band, the second antenna is a device of another main set receiving path PRX in the low frequency Band LB, and the second antenna is used for transmitting and receiving a second radio frequency signal in an operating Band corresponding to the NR Band 8. Therefore, the influence of the second radio frequency signal on the first radio frequency signal is slowed down by switching the antenna, so that the signal to noise ratio of the first radio frequency signal is improved, and the receiving performance of the first radio frequency signal is further improved.
It should be noted that, in this embodiment, the descriptions of the same steps and the same content as those in other embodiments may refer to the descriptions in other embodiments, and are not repeated here.
An embodiment of the present application provides a signal transmission method, applied to an electronic device, and referring to fig. 4, the method includes the following steps:
Step 401, a first signal-to-noise ratio of a first radio frequency signal is obtained in a process that the first antenna of the electronic device receives the first radio frequency signal and the first antenna transmits a second radio frequency signal.
Wherein, there is an overlapping portion between the receiving frequency range of the first radio frequency signal and the transmitting frequency range of the second radio frequency signal.
Step 402, if the first snr is not within the snr threshold, acquiring a transmit power of the second rf signal.
In the embodiment of the application, the transmitting power refers to the signal strength of the radio frequency signal transmitted by the electronic equipment, and the transmitting power is related to the transmission distance of the radio frequency signal, namely the larger the transmitting power is, the longer the transmission distance of the radio frequency signal is, the smaller the transmitting power is, and the shorter the transmission distance of the radio frequency signal is.
Step 403, sequentially reducing the transmitting power by an adjustment step, receiving the first radio frequency signal by the first antenna at a constant receiving power, and transmitting the second radio frequency signal by the reduced transmitting power each time by a selected one of the first antenna and the second antenna of the electronic device.
In the embodiment of the application, when the electronic equipment determines that the first signal-to-noise ratio is not in the signal-to-noise ratio threshold range, the electronic equipment acquires the transmitting power of the second radio frequency signal, adjusts the transmitting power, namely sequentially reduces the transmitting power through adjusting the step length to obtain the transmitting power after each reduction, and then, under the condition that the electronic equipment receives the first radio frequency signal through the first antenna with constant receiving power, the electronic equipment can select the first antenna to continuously transmit the second radio frequency signal with the transmitting power after each reduction and can select the second antenna to continuously transmit the second radio frequency signal with the transmitting power after each reduction, so that the transmitting power of the second radio frequency signal is reduced, and noise generated by the second radio frequency signal to the first radio frequency signal is reduced to improve the signal-to-noise ratio of the first radio frequency signal, and the receiving performance of the first radio frequency signal is improved.
In the embodiment of the present application, step 403 sequentially reduces the transmitting power by an adjustment step, receives the first radio frequency signal by the first antenna with a constant receiving power, and transmits the second radio frequency signal by the reduced transmitting power each time by a selected one of the first antenna and the second antenna of the electronic device, which may be implemented by the following steps:
and reducing the transmitting power by adjusting the step length until the first antenna is used for determining that the second radio frequency signal is transmitted by the reduced transmitting power through the first antenna and a selected antenna in the second antenna of the electronic equipment in the process of receiving the first radio frequency signal by the constant receiving power, wherein the signal to noise ratio of the first radio frequency signal is in the signal to noise ratio threshold range, and the reduction of the transmitting power of the second radio frequency signal is stopped.
In the embodiment of the application, the determination of the reduced transmitting power may be that the electronic device adjusts the transmitting power of the second radio frequency signal once to obtain the reduced transmitting power meeting the condition, or may be that the electronic device adjusts the transmitting power of the second radio frequency signal multiple times to obtain the reduced transmitting power meeting the condition. That is, the present application is not particularly limited to the adjusted number of cycles, so as to obtain the reduced transmission power satisfying the condition.
Here, if the reduced transmission power is obtained after the electronic device adjusts the transmission power of the second radio frequency signal once, the specific implementation process is as follows:
Firstly, the electronic equipment firstly reduces the transmitting power with an adjustment step length to obtain first reduced transmitting power, secondly, the electronic equipment obtains a third signal-to-noise ratio of the first radio frequency signal when the second radio frequency signal is transmitted with the first reduced transmitting power, thirdly, the electronic equipment determines that the third signal-to-noise ratio is within a signal-to-noise ratio threshold range, receives the first radio frequency signal with constant receiving power through the first antenna, transmits the second radio frequency signal with the first reduced transmitting power through one antenna selected from the first antenna and the second antenna of the electronic equipment, and finally, the electronic equipment stops reducing the transmitting power of the second radio frequency signal.
