Referring to fig. 3, fig. 3 is a schematic structural diagram of a radio frequency circuit in an electronic device according to an embodiment of the present disclosure.

The NSA dual-connection mode in NR mainly adopts a method of coexistence of LTE and NR, carries signaling transmission through an LTE network, carries data transmission through an NR network, and reduces the cost of NR deployment by sharing resources of an LTE base station. However, the LTE and NR sets of modems and the corresponding rf front-end modules are started simultaneously, i.e. when the NR modem is working, the LTE modem must be turned on simultaneously. For NR, the frequency band is higher and a high-order modulation mode is adopted, higher frequency means higher path loss, and high-order modulation means higher peak-to-average ratio, i.e. higher linearity and lower power amplification efficiency, so that a terminal is required to transmit higher power and higher power consumption in order to achieve the same signal strength.
In the embodiment of the application, when the data volume of the transmitted radio frequency signal is small, the data is transmitted only through the second transmission path 240 for transmitting the 4G radio frequency signal, and the first transmission path 220 with higher power consumption does not work, so that the power consumption is reduced. When the data volume of the transmitted rf signal is large, the first transmission path 220 and the second transmission path 240 transmit simultaneously, and the second transmission path 240 with smaller power consumption can transmit a part of the rf signal, thereby reducing the overall power consumption of the rf circuit 200.
Referring to fig. 4, fig. 4 is a schematic view of another structure of a radio frequency circuit in an electronic device according to an embodiment of the present disclosure. The first transmission path 220 may include a first modem 222, a first rf transceiver module 224, and a first power amplifier 226; the second transmission path 240 may include a second modem 242, a second radio frequency transceiver module 244, and a second power amplifier 246.
The first modem 222 may be a 5G modem for processing 5G rf signals. The first modem 222 is connected to the first antennas ANT1-ANT4 through the first rf transceiving module 224 and the first power amplifier 226. The second modem 242 may be a 4G modem for processing 4G rf signals. The second modem 242 is connected to the second antennas ANT5-ANT6 through the second rf transceiving module 244 and the second power amplifier 246,
wherein the number of the first antennas is at least 4, the number of the second antennas is at least 2, the first antennas and the second antennas may be different antennas, that is, the electronic device includes at least 6 antennas, and the first antennas and the second antennas may also be multiplexed, that is, the electronic device includes at least 4 antennas, for example, the electronic device includes 4 antennas, 4 antennas are used for transmitting 5G signals of the first modem 222, and at least two antennas of the 4 antennas may also be used for transmitting 4G signals of the second modem 242.
The following description will be given taking an example in which the first antenna is 4 first antennas.
The first modem 222 may be connected to 4 first antennas through a first switching element 228, the first switching element 228 being used to connect the first modem 222 to different first antennas at different time periods.
The second modem 242 may be connected with 2 second antennas through a second switching element for connecting the second modem 242 with different first antennas at different time periods. The second modem 242 may also be connected to a second antenna (e.g., ANT5) through the receiving module, and the second modem 242 may be connected to another second antenna (e.g., ANT6) through the transmitting module, i.e., without a second switching element. The distinction is made by the second radio frequency transceiver module 244.
Wherein the first power amplifier 226 is disposed between the first modem 222 and the first switching element, and the second power amplifier 246 is disposed between the second modem 242 and the second switching element.
The first modem 222 and the second modem 242 may also both be connected to 4 antennas through one first switching element 228, the first switching element 228 being used to connect the first modem 222 and the second modem 242 to different antennas at different time periods. The 4 antennas are all first antennas, wherein at least 2 antennas are second antennas, and at least 2 first antennas are multiplexed to be second antennas.
The rf circuit 200 may further include a baseband circuit coupled to the second modem 242 and the first modem 222. The baseband circuit is used for processing communication data of the radio frequency circuit 200 and controlling the working state of each device in the radio frequency circuit 200 according to the interaction information with the base station or the network server. It is understood that the baseband circuit may be integrated into the processing module of the electronic device 100, or may be independent of a separate processing circuit or processing chip. The processor 260 in this embodiment may be a chip of a baseband circuit, or may be a main chip of an electronic device.
The modem 202 is connected to the baseband circuit. The modem 202 is used for processing 5G radio frequency signals. For example, modem 202 may modulate upstream signals passing through modem 202 and demodulate downstream signals passing through modem 202.
It is understood that the uplink signal refers to a radio frequency signal transmitted by the radio frequency circuit 200 to the outside through the antenna, and the downlink signal refers to a radio frequency signal received by the radio frequency circuit 200 from the outside through the antenna.
It is understood that the 5G signal of the first SIM card refers to a signal when the electronic device 100 wirelessly communicates with a base station or other electronic devices through information stored in the first SIM card in a fifth generation mobile communication technology.
In the rf circuit 200, the transmission process of the uplink signal is as follows:
the processing module 201 processes the 5G signal of the first SIM card to be transmitted to the outside, and then transmits the processed 5G signal of the first SIM card to the modem 202 for modulation. The modem 202 modulates the 5G signal of the first SIM card, transmits the modulated 5G signal of the first SIM card to the antenna, and transmits the modulated 5G signal of the first SIM card to the outside through the antenna.
In the rf circuit 200, the transmission process of the downlink signal is as follows:
after receiving the 5G signal associated with the first SIM card from the outside, the antenna transmits the received downlink 5G signal of the first SIM card to the modem 202 for demodulation. It is understood that the 5G signal associated with the first SIM card refers to the 5G signal when the base station or other electronic equipment performs wireless communication with the electronic equipment 100 through the subscriber identity information stored in the first SIM card (for example, the first telephone number stored in the first SIM card and used for representing the subscriber identity). After receiving the downlink 5G signal of the first SIM card, the modem 202 demodulates the downlink 5G signal of the first SIM card, and transmits the demodulated 5G signal to the processing module 201 for processing.
In some embodiments, when the data amount is greater than the first preset threshold, the processor 260 is further configured to obtain a first duration for transmitting the radio frequency signal; when the first time length is greater than the first preset time length threshold, the processor 260 is configured to control the first transmission path 220 and the second transmission path 240 to simultaneously transmit the radio frequency signal; when the first duration is not greater than the first preset duration threshold, the processor 260 is configured to control the first transmission path 220 to transmit the rf signal.
The processor 260 may calculate the first time length of the radio frequency signal to be transmitted according to transmission only through the first transmission path, or may calculate the first time length of the radio frequency signal to be transmitted according to transmission only through the second transmission path 240, where of course, the first preset time length thresholds corresponding to different transmission paths are also different. The first time length can also be calculated by taking the current communication quality into account and transmitting a test signal.
The processor 260 not only controls the rf circuit 200 according to the data amount of the rf signal to be transmitted, but also controls the first time period for transmitting the rf signal to be transmitted.
Specifically, when the data amount of the radio frequency signal to be transmitted is greater than a first preset threshold and the first duration for transmitting the radio frequency signal to be transmitted is greater than a first preset duration threshold, the radio frequency signal is transmitted through the first transmission path 220 and the second transmission path 240 at the same time;
when the data amount of the radio frequency signal to be transmitted is greater than the first preset threshold and the first duration for transmitting the radio frequency signal to be transmitted is not greater than the first preset duration threshold, the radio frequency signal is transmitted through the first transmission path 220.
It can also be understood that when the radio frequency signal is transmitted with a large data volume for a long time (the data volume of the radio frequency signal to be transmitted is greater than the first preset threshold, and the first duration of transmitting the radio frequency signal to be transmitted is greater than the first preset duration threshold), the radio frequency signal is transmitted through the first transmission path 220 and the second transmission path 240 simultaneously. At the moment, the transmission is carried out in a mode of combining NR and LTE, a high data transmission rate is obtained by using a large bandwidth and a high-order modulation mode of NR, meanwhile, partial data are transmitted by using LTE, the overall power consumption is reduced, better user experience is obtained, and the power consumption is reduced while the advantage of NR is fully exerted. When the radio frequency signal is transmitted in a short time with a large data volume (the data volume of the radio frequency signal to be transmitted is greater than the first preset threshold, and the first time length for transmitting the radio frequency signal to be transmitted is not greater than the first preset time length threshold), the radio frequency signal is transmitted through the first transmission path 220. By using the NR technique based on Discontinuous Reception (DRX), the data is quickly transmitted and then enters a sleep state, which saves power consumption and does not cause excessive delay. In the Discontinuous Reception (DRX), the corresponding UE (electronic device or radio frequency circuit 200) periodically enters a sleep mode at some time without monitoring a Physical Downlink Control Channel (PDCCH) subframe. By sleeping the first transmission path 220 (the NR modem, etc.), power consumption is reduced, and power saving is achieved.
The power consumption of the radio frequency circuit is mainly concentrated in the modems (4G modem, 5G modem) and the transmission path, and the large data volume generally comes from the downlink, so that in the long-time large data volume transmission of radio frequency signals, the uplink signal of the radio frequency signals to be transmitted is transmitted by using the second transmission path 240(LTE path) and the downlink signal of the radio frequency signals to be transmitted is received by using the first transmission path (NR path) by using the uplink and downlink asymmetric systems. Specifically, in the long-time large-data-volume transmission of the radio frequency signal, the processor 260 is configured to control the first transmission path 220 to receive a downlink signal of the radio frequency signal to be transmitted, and control the second transmission path 240 to transmit an uplink signal of the radio frequency signal to be transmitted.
The rf circuit 200 is located on the circuit board 104, and the circuit board 104 is located in the housing 106.
For the scheme of distributing the radio frequency signals to be transmitted, distribution can be carried out through the current electric quantity. Specifically, the electronic device 100 further includes a battery 105, and the battery 105 is electrically connected to the processor 260. The processor 260 is further configured to obtain a current power level of the electronic device; dividing the radio frequency signal to be transmitted into a first part and a second part according to the current electric quantity; and controls the first transmission path 220 to transmit the first portion and the second transmission path 240 to transmit the second portion.
The radio frequency signal to be transmitted is divided into a first part and a second part according to the current electric quantity, and the first part and the second part can be carried out according to a preset formula. The preset formula is used for distributing more radio frequency signals to be transmitted to LTE when the current electric quantity is lower, so that the purpose of saving electricity is achieved.
For example, the processor 260 may determine the preset formula B ═ a × X1.5And C, dividing the radio frequency signal to be transmitted into a first part and a second part, wherein A is the radio frequency signal to be transmitted, X is the current electric quantity, B is the first part, and C is the second part. The allocation is performed in conjunction with the current power level of the electronic device. For example, the data amount of the radio frequency signal to be transmitted is 1GB of data, the current electric quantity X is 0.5 (which can also be understood as 50%), a is divided into B and C, where B is the data B assigned to NR (a X)1.5 ＝1*0.51.5The quantity C of the radio frequency signals to be transmitted is 1000M-353M-647M, namely, the lower the current electric quantity X is, more radio frequency signals to be transmitted are distributed to the LTE, so that the purpose of saving power is achieved.
Of course, the preset formula is only an exemplary example, and in other embodiments, the preset formula may be another formula. For example, the predetermined formula may be B ═ a × X1.6、B＝A*X1.4、B＝A*X1.5+ D, etc. thereofAnd D is a compensation value, and can be obtained according to at least one item of current electric quantity, historical user electricity utilization information, historical user radio frequency signal information and the like.
It is particularly pointed out that it is currently in the construction and development stage of 5G networks. 5G networks have specificity with respect to 4G networks.
Depending on the requirements of the communication protocol, a complete 4G network communication link requires at least 2 antennas to implement, and a complete 5G network communication link requires at least 4 antennas to implement. In a communication link formed by at least 4 antennas of a 5G network, it is necessary to maintain one antenna to implement SRS (Sounding Reference Signal) communication between an electronic device and a base station. That is, in a 5G network communication link between an electronic device and a base station, it is necessary to keep an antenna transmitting SRS signals to the base station, and the base station evaluates the quality of downlink channels between the base station and the electronic device through the received SRS signals, thereby facilitating the resource allocation of the downlink channels between the base station and the electronic device. However, according to the requirements of the communication protocol, the SRS signal needs to be switched between at least 4 antennas of the 5G network communication link. That is, the electronic device sequentially transmits the SRS signal to the base station in a time division manner through each of the at least 4 antennas of the 5G network communication link. The SRS signal does not carry communication content of communication between the user and other users, and is only used for the base station to evaluate the quality of the downlink channel.
Referring to fig. 5, fig. 5 is a first flowchart illustrating a signal transmission method according to an embodiment of the present disclosure. The signal transmission method in the embodiment of the application is applied to electronic equipment, and the electronic equipment may be the electronic equipment in any embodiment of the above embodiments. The electronic equipment comprises a first transmission path and a second transmission path, wherein the first transmission path is used for transmitting 5G radio frequency signals, and the second transmission path is used for transmitting 4G radio frequency signals. The signal transmission method specifically comprises the following steps:
301, acquiring the data volume of the radio frequency signal to be transmitted in a non-independent networking state;
302, when the data volume is larger than a first preset threshold value, simultaneously transmitting radio frequency signals through a first transmission channel and a second transmission channel;
303, when the data volume is not greater than the first preset threshold value, transmitting the radio frequency signal through the second transmission path.
The NSA dual-connection mode in NR mainly adopts a method of coexistence of LTE and NR, carries signaling transmission through an LTE network, carries data transmission through an NR network, and reduces the cost of NR deployment by sharing resources of an LTE base station. However, the LTE and NR sets of modems and the corresponding rf front-end modules are started simultaneously, i.e. when the NR modem is working, the LTE modem must be turned on simultaneously. For NR, the frequency band is higher and a high-order modulation mode is adopted, higher frequency means higher path loss, and high-order modulation means higher peak-to-average ratio, i.e. higher linearity and lower power amplification efficiency, so that a terminal is required to transmit higher power and higher power consumption in order to achieve the same signal strength.
According to the embodiment of the application, when the data volume of the transmitted radio frequency signal is small, the data is transmitted only through the second transmission channel for transmitting the 4G radio frequency signal, the first transmission channel with higher power consumption does not work, and the power consumption is reduced. When the data volume of the transmitted radio frequency signal is large, the radio frequency signal is transmitted through the first transmission channel and the second transmission channel simultaneously, the second transmission channel with lower power consumption can transmit part of the radio frequency signal, and the whole power consumption of the radio frequency circuit is reduced.
When the data amount is greater than the first preset threshold, the simultaneously transmitting the radio frequency signal through the first transmission path and the second transmission path may specifically include:
when the data volume is larger than a first preset threshold value, acquiring a first time length for transmitting a radio frequency signal;
when the first time length is larger than a first preset time length threshold value, simultaneously transmitting radio frequency signals through a first transmission channel and a second transmission channel;
and when the first time length is not greater than a first preset time length threshold value, transmitting the radio frequency signal through a first transmission channel.
The first duration of the radio frequency signal to be transmitted can be calculated according to transmission only through the first transmission channel, and the first duration of the radio frequency signal to be transmitted can also be calculated according to transmission only through the second transmission channel, and certainly, the first preset duration thresholds corresponding to different transmission channels are also different. The first time length can also be calculated by taking the current communication quality into account and transmitting a test signal.
The radio frequency circuit is controlled according to the data volume of the radio frequency signal to be transmitted and the first time length of the radio frequency signal to be transmitted. Specifically, when the data volume of the radio frequency signal to be transmitted is greater than a first preset threshold value and the first time length for transmitting the radio frequency signal to be transmitted is greater than a first preset time length threshold value, the radio frequency signal is transmitted simultaneously through a first transmission channel and a second transmission channel;
and when the data volume of the radio-frequency signal to be transmitted is greater than a first preset threshold value and the first time length for transmitting the radio-frequency signal to be transmitted is not greater than a first preset time length threshold value, transmitting the radio-frequency signal through a first transmission channel.
It can also be understood that when the radio frequency signal is transmitted in a large data volume for a long time (the data volume of the radio frequency signal to be transmitted is greater than the first preset threshold, and the first time length for transmitting the radio frequency signal to be transmitted is greater than the first preset time length threshold), the radio frequency signal is transmitted through the first transmission path and the second transmission path simultaneously. At the moment, the transmission is carried out in a mode of combining NR and LTE, a high data transmission rate is obtained by using a large bandwidth and a high-order modulation mode of NR, meanwhile, partial data are transmitted by using LTE, the overall power consumption is reduced, better user experience is obtained, and the power consumption is reduced while the advantage of NR is fully exerted. When the radio frequency signal is transmitted in a short time and a large amount of data (the data amount of the radio frequency signal to be transmitted is greater than a first preset threshold value, and the first time length for transmitting the radio frequency signal to be transmitted is not greater than a first preset time length threshold value), the radio frequency signal is transmitted through a first transmission channel. By using the NR technique based on Discontinuous Reception (DRX), the data is quickly transmitted and then enters a sleep state, which saves power consumption and does not cause excessive delay. In the Discontinuous Reception (DRX), a corresponding UE (electronic device or radio frequency circuit) periodically enters a sleep mode at some time without monitoring a Physical Downlink Control Channel (PDCCH) subframe. The first transmission path (NR modem, etc.) is dormant to reduce power consumption and save power.
The simultaneously transmitting the radio frequency signal through the first transmission path and the second transmission path may specifically include:
and receiving a downlink signal of the radio-frequency signal to be transmitted through the first transmission channel, and transmitting an uplink signal of the radio-frequency signal to be transmitted through the second transmission channel.
The power consumption of the radio frequency circuit is mainly concentrated in the modems (4G modem, 5G modem) and the transmission path, and the large data volume generally comes from the downlink, so that the uplink signal of the radio frequency signal to be transmitted can be transmitted by using the second transmission path (LTE path) and the downlink signal of the radio frequency signal to be transmitted can be received by using the first transmission path (NR path) in the long-time large data volume transmission radio frequency signal by using the uplink and downlink asymmetric system.
The simultaneously transmitting the radio frequency signal through the first transmission path and the second transmission path may specifically include:
acquiring the current electric quantity of the electronic equipment;
dividing a radio frequency signal to be transmitted into a first part and a second part according to the current electric quantity;
the first portion is transported through a first transport path and the second portion is transported through a second transport path.
The radio frequency signal to be transmitted is divided into a first part and a second part according to the current electric quantity, and the first part and the second part can be carried out according to a preset formula. The preset formula is used for distributing more radio frequency signals to be transmitted to LTE when the current electric quantity is lower, so that the purpose of saving electricity is achieved.
Dividing the radio frequency signal to be transmitted into a first part and a second part according to the current electric quantity may specifically include:
according to a predetermined formula B ═ A × X1.5C-a-B divides the radio frequency signal to be transmitted into a first part and a second part, wherein a is the radio frequency signal to be transmitted,x is the current electric quantity, B is the first part, C is the second part.
The allocation is performed in conjunction with the current power level of the electronic device. For example, the data amount of the radio frequency signal to be transmitted is 1GB of data, the current electric quantity X is 0.5 (which can also be understood as 50%), a is divided into B and C, where B is the data B assigned to NR (a X)1.5＝1*0.51.5The quantity C of the radio frequency signals to be transmitted is 1000M-353M-647M, namely, the lower the current electric quantity X is, more radio frequency signals to be transmitted are distributed to the LTE, so that the purpose of saving power is achieved.
Of course, the preset formula is only an exemplary example, and in other embodiments, the preset formula may be another formula. For example, the predetermined formula may be B ═ a × X1.6、B＝A*X1.4、B＝A*X1.5And D, wherein D is a compensation value, and can be obtained according to at least one item of current electric quantity, historical user electricity utilization information, historical user radio frequency signal information and the like.
The signal transmission method may further include:
acquiring historical electric quantity information, historical data quantity information, first historical power consumption information of a first transmission path and second historical power consumption information of a second transmission path;
inputting historical electric quantity information, historical data quantity information, first historical power consumption information and second historical power consumption information into a preset model for training to obtain a trained preset model, wherein the trained preset model is used for adjusting parameters of a preset formula;
dividing the radio frequency signal to be transmitted into a first part and a second part according to the current electric quantity may specifically include:
inputting the current electric quantity and the data quantity into the trained preset model to obtain a preset formula after adjusting parameters;
and dividing the radio frequency signal to be transmitted into a first part and a second part according to a preset formula after the parameters are adjusted.
The preset model can be trained according to the historical electric quantity information, the historical data quantity information, the first historical power consumption information and the second historical power consumption information, and preset formulas which accord with different users are obtained. Preset dieThe model is used to adjust the parameters of the preset formula, so the trained preset model can be used to adjust the parameters of the preset formula of the corresponding user. And when the model is actually used, inputting the current electric quantity and the data quantity into the trained preset model to obtain a preset formula after the parameters are adjusted. For example, the predetermined formula before adjusting the parameters is B ═ a × X1.5And C is A-B, and after parameters are adjusted according to the trained preset model, the preset formula can be B is A X1.5And C is A-B, and after parameters are adjusted according to the trained preset model, the preset formula can be B is A X1.5+ a 0.1, C ═ a-B. The lower the electric quantity is, the larger the value of B is, which is beneficial to saving power consumption and preventing the electronic equipment from being shut down due to too low electric quantity.
