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 application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The radio frequency circuit, the signal transmission method, and the electronic device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1 and 2, fig. 1 is a schematic diagram of a frequency range of a partial 5G NR frequency band, and fig. 2 is a schematic diagram of a frequency range of a GSM partial frequency band. As shown in fig. 1 and 2, the frequencies of the N1/N3 band of 5G and the DCS/PCS band of 2G are very similar, while 2G and 5G are usually not used simultaneously, i.e. only one of the two bands is in operation at the same time; currently, the transmission power of 5G N1 and N3 frequency bands is usually designed according to 23dbm, i.e. the transmission power is 0.2W, while the transmission power of 2G DCS and PCS is designed according to 30dbm, i.e. the transmission power is 1W, which is a 5-fold relationship.
However, when the electronic device is far away from the base station, the terminal will fall back from the 5G network to the 4G network or even the 2G network due to insufficient transmission power, and effective camping cannot be achieved.
Therefore, referring to fig. 3, fig. 3 is a schematic structural diagram of a radio frequency circuit according to an embodiment of the present disclosure. As shown in fig. 3, the radio frequency circuit provided in the embodiment of the present application may include: the radio frequency transceiver comprises a radio frequency transceiver 31, a first power amplifier 321, a second power amplifier 322, a first antenna 331, a second antenna 332 and a switch 34, wherein a first signal transmitting terminal TX1 and a second signal transmitting terminal TX2 of the radio frequency transceiver are both connected with the switch 34, the first signal transmitting terminal TX1 is used for transmitting a first signal, and the second signal transmitting terminal TX2 is used for transmitting a second signal; the switch 34 is also connected to a first power amplifier 321 and a second power amplifier 322, respectively, and the first power amplifier 321 is connected to the first antenna 331 and the second power amplifier 322 is connected to the second antenna 332; when the transmission power of the first power amplifier 321 meets a first preset condition, the switch 34 may be configured to control the first signal transmitting end TX1 to be connected to the second power amplifier 322, that is, the switch 34 may be configured to control the first signal transmitting end TX1 to be switched from being connected to the first power amplifier 321 to being connected to the second power amplifier 322, so that the first signal transmitting end TX1 may transmit a first signal through the second power amplifier 322 and the second antenna 332; on the other hand, when the transmission power of the second power amplifier 322 does not satisfy the first preset condition, the switch 34 may be configured to control the first signal transmitting terminal TX1 to be connected to the first power amplifier 321, that is, the switch 34 may be configured to control the first signal transmitting terminal TX1 to be switched from being connected to the second power amplifier 322 to be connected to the first power amplifier 321, so as to transmit the first signal through the first power amplifier and the first antenna, thereby saving power consumption, and may transmit the second signal through the second antenna 332 when the first signal is not transmitted.
Therefore, in the embodiment of the present invention, when the electronic device is far from the base station or when the first signal is influenced by a large number of obstacles between the electronic device and the base station, the first signal may be transmitted by using the second power amplifier 322 and the second antenna 332 that are originally used for transmitting the second signal.
In an alternative embodiment, the switch 34 may be a double pole double throw switch.
In this embodiment of the application, the first preset condition that the transmission power of the first power amplifier 321 meets the first preset condition may specifically be: within the preset time period, the transmission power of the first power amplifier 321 continuously exceeds or is equal to a certain preset threshold, for example, the transmission power of the first power amplifier 321 within the preset time period continuously reaches its own maximum transmission power, which indicates that the distance between the electronic device and the base station is long, or there are many obstacles between the electronic device and the base station, and even if the transmission power of the first signal has maintained the maximum power, the communication connection with the base station still cannot be maintained.
The transmitting power of the second power amplifier 322 not meeting the first preset condition may be: the second power amplifier 322 is still working, but the transmission power is lower than a certain preset threshold, then the first signal is transmitted without using the high power of the second power amplifier 322, and only the first power amplifier 321 is switched back to transmit the first signal with the smaller power, so that the power consumption can be reduced after switching; meanwhile, after the first signal transmitting terminal TX1 is switched from being connected to the second power amplifier 322 to being connected to the first power amplifier 321, if the first power amplifier 321 is no longer working, i.e. no longer communicating with the first signal, the electronic device may be allowed to transmit the second signal through the second power amplifier 322 and the second antenna 332 to perform the communication connection.
In this embodiment of the application, the frequency of the first signal and the second signal output by the second signal sending end of the radio frequency transceiver should satisfy a second preset condition, where the second preset condition may be: the difference value between the frequency of the first signal and the frequency of the second signal is within a preset range, so that the second power amplifier can perform power amplification on the first signal. For example, the frequency of the first signal and the frequency of the mobile data network signal have a certain overlapping frequency, or the maximum frequency of the first signal and the minimum frequency of the second signal differ by no more than 100 MHz.
In an optional embodiment, a frequency band of the first signal is a 5G N1 or N3 frequency band, a frequency band of the second signal is a 2G PCS frequency band or DCS frequency band, and the frequency ranges of the frequency bands are please refer to fig. 1 and fig. 2, which is not repeated herein. Because the transmitting power of the second power amplifier adopted by the PCS frequency band or the DCS frequency band of 2G is 5 times of the transmitting power of the first power amplifier adopted by the N1 frequency band or the N3 frequency band of 5G, the strength of the first signal can be effectively improved, the success rate of residing in a 5G network is improved, and meanwhile, the requirement of low power consumption can be met. Wherein the power of the second power amplifier 322 for transmitting signals of PCS band or DCS band of 2G is typically designed to be 30dbm, i.e. 1W, and the power of the first power amplifier 321 for transmitting signals of N1 or N3 band of 5G is typically designed to be 23dbm, i.e. 0.2W; at this time, the first preset condition may be that the transmission power is higher than 23 dbm.
In this embodiment, optionally, a first signal receiving end of the radio frequency transceiver 31 is respectively connected to the first antenna 331 and the second antenna 332, so that the first signal can be received by the first antenna 331 and the first signal can be received by the second antenna 332; and a second signal receiving end of the radio frequency transceiver is connected to the second antenna 332 so as to receive a second signal through the second antenna 332.
Optionally, the scheme of the embodiment of the present application may also be applied to the switching application of the corresponding power amplifier when the frequency of the 4G, 3G, and 2G signals meets a certain condition, so as to improve the success rate of residing in the 4G network.
In the embodiment of the application, when the electronic device is far away from the base station and the transmission power of the first power amplifier of the first signal cannot meet the communication requirement, the first signal is transmitted through the power amplifier and the second antenna which are originally used for transmitting the second signal, so that the transmission power of the first signal can be effectively improved, and the electronic device can be ensured to reside in the network cell corresponding to the first signal.
Please refer to fig. 4, which is a flowchart illustrating a signal transmitting method according to an embodiment of the present application. As shown in fig. 4, another embodiment of the present application further provides a signal transmission method, which is applied to the radio frequency circuit described in the foregoing embodiment, and the signal transmission method includes the following steps:
step 41: under the condition that the transmitting power of the first power amplifier meets a first preset condition, controlling a selector switch to connect the first signal transmitting end with the second power amplifier so as to transmit a first signal through the second power amplifier and the second antenna;
step 42: and under the condition that the transmitting power of the second power amplifier does not meet a first preset condition, controlling a change-over switch to connect the first signal transmitting end with the first power amplifier so as to transmit a first signal through the first power amplifier and the first antenna.
That is to say, in an initial state, the change-over switch controls the first signal transmitting terminal to be connected with the first power amplifier, and the first signal transmitting terminal of the radio frequency transceiver outputs a first signal which is amplified by the first power amplifier and then transmitted through the first antenna; after the first power amplifier starts working, detecting the transmission power value of the first power amplifier, if the transmission power of the first power amplifier does not satisfy a first preset condition, for example, the maximum transmission power is not reached, maintaining the connection between the first signal transmitting end and the first power amplifier, if the transmission power of the first power amplifier satisfies the first preset condition, for example, the maximum transmission power is reached, it is determined that the distance between the electronic device and the base station is long, or there are many obstacles between the electronic device and the base station, even if the transmission power of the first power amplifier maintains the maximum power, the first signal is still weak and cannot effectively reside in the currently connected network, therefore, the first signal transmitting end is controlled to be connected with the second power amplifier by using the switch, that is, the first signal transmitting end is controlled to be switched from being connected with the first power amplifier to being connected with the second power amplifier by using the switch, because the transmitting power of the second power amplifier is greater than that of the first power amplifier, the first signal can be transmitted by the second antenna with a transmitting power greater than the original transmitting power, so that the strength of the transmitted first signal is enhanced, and the success rate of residing in the current network is improved; after the switch is switched, a transmission power value of the second power amplifier is detected, if the transmission power of the second power amplifier does not meet a first preset condition, for example, the transmission power is lower than the maximum transmission power of the first power amplifier, it indicates that the distance between the electronic device and the base station is relatively short, and the first signal does not need to be sent through the second power amplifier and the second antenna, the switch can be controlled to connect the first signal sending end with the first power amplifier, that is, the switch is controlled to switch the first signal sending end from being connected with the second power amplifier back to being connected with the first power amplifier, so as to reduce transmission power consumption, and allow the electronic device to normally receive and send the second signal through the second power amplifier and the second antenna when the electronic device does not use the first signal for communication.
In an optional embodiment, a frequency band of the first signal is an N1 or N3 frequency band of 5G, a frequency band of the second signal is a PCS frequency band or DCS frequency band of 2G, and reference is made to fig. 1 and fig. 2 for frequency ranges of the frequency bands, which are not repeated herein. Because the transmitting power of the second power amplifier adopted by the PCS frequency band or the DCS frequency band of 2G is 5 times of the transmitting power of the first power amplifier adopted by the N1 frequency band or the N3 frequency band of 5G, the strength of the first signal can be effectively improved, the success rate of residing in a 5G network is improved, and meanwhile, the requirement of low power consumption can be met.
The specific content of meeting/not meeting the first preset condition is the same as that described in the above embodiment of the radio frequency circuit, and is not described herein again.
Optionally, the scheme of the embodiment of the present application may also be applied to switching application of a corresponding power amplifier when the frequency of the 4G, 3G, and 2G signals meets a certain condition, so as to improve the success rate of residing in the 4G network.
In this embodiment, optionally, the signal transmitting method further includes:
and under the condition that the second power amplifier is connected with the second signal sending end and the first power amplifier does not work, sending a second signal through the second power amplifier and the second antenna.
Specifically, when the switch controls the first signal transmitting terminal to be connected to the first power amplifier and the second signal transmitting terminal to be connected to the second power amplifier, if the first signal is not used for communication connection, that is, the first power amplifier is not operating, the second signal may be transmitted through the second power amplifier and the second antenna, so as to meet the communication connection requirement between the electronic device and the base station.
In the embodiment of the application, when the electronic device is far away from the base station and the transmission power of the first power amplifier of the first signal cannot meet the communication requirement, the first signal is transmitted through the power amplifier and the second antenna which are originally used for transmitting the second signal, so that the transmission power of the first signal can be effectively improved, and the electronic device can be ensured to reside in the network cell corresponding to the first signal.
