Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures. 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", etc. in this application are used to distinguish between different objects and not to describe a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
In full duplex communication technology, communication allows data to be transmitted simultaneously in both directions, which corresponds in capability to a combination of two simplex communication modes. Full duplex refers to the simultaneous (instantaneous) transmission of signals in both directions (a → B and B → a). A → B and B → A are instantaneously synchronized.
The communication between the electronic device such as the smart phone and the base station includes uplink communication and downlink communication, wherein the uplink communication means that the electronic device sends a signal to the base station, and the downlink communication means that the electronic device receives the signal from the base station.
In one communication mode, uplink communication and downlink communication between an electronic device such as a smart phone and a base station are simultaneously performed, and the uplink communication frequency band and the downlink communication frequency band are not overlapped with each other.
For example, FDD (Frequency Division Duplexing) is one of full duplex communication techniques used in mobile communication systems, and corresponds to TDD (Time Division Duplexing). FDD employs two separate channels for downward transmission (downlink communication) and upward transmission of information (uplink communication). To prevent mutual interference between adjacent transmitters and receivers, a guard band exists between the two channels.
FDD operation requires two separate channels. One channel is used to transmit information from the base station to the electronic device and the other channel is used to transmit information from the electronic device to the base station.
Taking the B1 band of LTE (Long Term Evolution ) as an example, the uplink communication band for communication between the electronic device and the base station is 1920-1980MHz, and the downlink communication band 2110-2170MHz for communication between the electronic device and the base station, where the two bands do not overlap each other. Usually, we choose a compromise way to implement uplink communication and downlink communication simultaneously, i.e. control the resonant frequency of the antenna of the electronic device to be around 2000MHz, and the efficiency of uplink communication and downlink communication of the electronic device is basically equivalent.
In an environment where the strength of the uplink signal and the strength of the downlink signal are not consistent, in this case, the strength of the uplink signal and the strength of the downlink signal are detected, and the resonant frequency of the antenna is adjusted according to the detected strength of the uplink signal and the detected strength of the downlink signal, so that both the strength of the uplink signal and the strength of the downlink signal can meet the communication requirement, which is specifically described in the following embodiments.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a control method of an electronic device according to a first embodiment of the present application.
In this embodiment, the control method of the electronic device may include the steps of:
step 101: the method includes detecting an uplink signal strength of communication between the electronic device and the base station, and detecting a downlink signal strength of communication between the electronic device and the base station.
The processor of the electronic device is matched with the antenna of the electronic device to detect the strength of an uplink signal communicated between the electronic device and the base station; meanwhile, the processor of the electronic device cooperates with the antenna of the electronic device to detect the downlink signal strength of the communication between the electronic device and the base station.
It should be understood that the uplink signal strength and the downlink signal strength are both the signal strength of the current location of the electronic device. For example, the uplink signal strength is the signal strength of a signal transmitted by the electronic device to the base station; the downlink signal strength is the signal strength of a signal received by the electronic device from the base station.
Step 102: and when the uplink signal strength is detected to be lower than the downlink signal strength, controlling the resonant frequency of the antenna of the electronic device to deflect to an uplink communication frequency band for communication between the electronic device and the base station.
When the processor is matched with the antenna to detect that the strength of the uplink signal is lower than that of the downlink signal, the resonance frequency of the antenna of the electronic device is controlled to deviate to the uplink communication frequency band for communication between the electronic device and the base station.
Specifically, the step of controlling the resonance frequency of the antenna of the electronic device to be biased to the uplink communication frequency band for communication between the electronic device and the base station may specifically include the following steps:
determining a current resonant frequency of an antenna according to a current matching state of an antenna tuner of the electronic device;
determining a target resonant frequency of the antenna according to the current resonant frequency, wherein the frequency value of the target resonant frequency is closer to the frequency interval of the uplink communication frequency band than the frequency value of the current resonant frequency;
determining a target matching state of the antenna tuner according to the target resonant frequency of the antenna;
and controlling the antenna tuner to adjust the resonant frequency of the antenna to the target resonant frequency according to the target matching state.
For example, the antenna tuner may include at least one of a variable capacitance, a variable resistance, a variable inductance, an antenna switch. The variable capacitor, the variable resistor, the variable inductor and the antenna switch have various states, and the states can be controlled by the processor. For example, each state of the variable capacitance corresponds to a capacitance value. The processor can change the capacitance value of the variable capacitor by controlling the voltage. The processor changes the matching state by changing a capacitance value, a resistance value, an inductance value, a switching state of the antenna switch and the like on the matching circuit, so that a plurality of different matching states are realized, and each matching state corresponds to a specific resonant frequency. The memory of the electronic device stores a corresponding relation table of the matching state and the resonant frequency.
Determining the current resonant frequency of the antenna according to the current matching state of the antenna tuner of the electronic device may specifically be: and searching the corresponding resonant frequency in the corresponding relation table of the matching state and the resonant frequency according to the current matching state to be used as the current resonant frequency.
Determining the target matching state of the antenna tuner according to the target resonant frequency of the antenna may specifically be: and searching a corresponding matching state according to the corresponding relation table of the target resonant frequency between the matching state and the resonant frequency to be used as a target matching state.
The following is a description of determining a target resonant frequency of an antenna based on a current resonant frequency. The frequency value of the target resonance frequency is closer to the frequency interval of the uplink communication frequency band than the frequency value of the current resonance frequency. For example, as mentioned above, the uplink communication band for communication between the electronic device and the base station is 1920-. Then the target resonance frequency can be determined to be any value between 1920-1999 MHz, and can be determined according to the adjusted gear and amplitude, for example, the target resonance frequency is preferably adjusted to a value between 1980-1999 MHz.
Step 103: and when the downlink signal strength is detected to be lower than the uplink signal strength, controlling the resonance frequency of the antenna of the electronic device to deflect to a downlink communication frequency band for communication between the electronic device and the base station.
The intervals of the uplink communication frequency band and the downlink communication frequency band are not overlapped with each other.
Controlling the resonant frequency of the antenna of the electronic device to be biased towards the downlink communication frequency band for communication between the electronic device and the base station may specifically include the following steps:
determining a current resonant frequency of an antenna according to a current matching state of an antenna tuner of the electronic device;
determining a target resonant frequency of the antenna according to the current resonant frequency, wherein the frequency value of the target resonant frequency is closer to the frequency interval of the downlink communication frequency band than the frequency value of the current resonant frequency;
determining a target matching state of the antenna tuner according to the target resonant frequency of the antenna;
and controlling the antenna tuner to adjust the resonant frequency of the antenna to the target resonant frequency according to the target matching state.
Determining the current resonant frequency of the antenna according to the current matching state of the antenna tuner of the electronic device may specifically be: and searching the corresponding resonant frequency in the corresponding relation table of the matching state and the resonant frequency according to the current matching state to be used as the current resonant frequency.
Determining the target matching state of the antenna tuner according to the target resonant frequency of the antenna may specifically be: and searching a corresponding matching state according to the corresponding relation table of the target resonant frequency between the matching state and the resonant frequency to be used as a target matching state.
The following is a description of determining a target resonant frequency of an antenna based on a current resonant frequency. The frequency value of the target resonance frequency is closer to the frequency section of the downlink communication band than the frequency value of the current resonance frequency. For example, as mentioned above, the uplink communication band for communication between the electronic device and the base station is 1920-. The target resonant frequency can be determined to be any value between 2001 and 2170MHz, and can be determined according to the adjusted gear and amplitude, for example, the target resonant frequency is preferably adjusted to a value between 2001 and 2110 MHz.
Referring to fig. 2, fig. 2 is a flowchart illustrating a control method of an electronic device according to a second embodiment of the present application.
In this embodiment, the control method of the electronic device may include the steps of:
step 201: the method includes detecting an uplink signal strength of communication between the electronic device and the base station at a first predetermined frequency and detecting a downlink signal strength of communication between the electronic device and the base station at a second predetermined frequency.
The processor is matched with the antenna to detect the strength of an uplink signal communicated between the electronic device and the base station according to a first preset frequency and detect the strength of a downlink signal communicated between the electronic device and the base station according to a second preset frequency.
For example, the detection at the first preset frequency may specifically be: and setting a preset detection time point for detecting the strength of the uplink signal within a preset time. The detection according to the second preset frequency may specifically be: and setting a preset detection time point for detecting the downlink signal intensity in a preset time.
Step 202: and when the uplink signal strength is detected to be lower than the first preset strength value for a first preset time, and the downlink signal strength is detected to be higher than the second preset strength value for a second preset time, controlling the resonant frequency of the antenna of the electronic device to deviate to an uplink communication frequency band for communication between the electronic device and the base station.
As mentioned above, for example, the number of detection time points set in the predetermined time is two, and the first preset number and the second preset number are both two. The uplink signal strength detected in two consecutive times is respectively T1 and T2, and the downlink signal strength detected in two consecutive times is respectively R1 and R2. The first preset intensity value is T, and the second preset intensity value is R. The first preset strength value may be a lowest signal strength value capable of satisfying uplink communication, and the second preset strength value may be a lowest signal strength value capable of satisfying downlink communication. Then, when both T1 and T2 are less than T, and both R1 and R2 are greater than R, the resonant frequency of the antenna of the control electronics is biased toward the uplink communication band of communications between the electronics and the base station. The second preset intensity value is greater than or equal to the first preset intensity value.
Step 203: and when the downlink signal strength is detected to be lower than a third preset strength value for a third preset time and the downlink signal strength is detected to be higher than a fourth preset strength value for a fourth preset time, controlling the resonant frequency of the antenna of the electronic device to deviate to a downlink communication frequency band for communication between the electronic device and the base station.
As mentioned above, for example, the number of detection time points set in the predetermined time is two, and the third preset number and the fourth preset number are both two. The uplink signal strength detected in two consecutive times is respectively T1 and T2, and the downlink signal strength detected in two consecutive times is respectively R1 and R2. The third preset intensity value is R and the fourth preset intensity value is T. The third preset strength value may be a lowest signal strength value capable of satisfying downlink communication, and the fourth preset strength value may be a lowest signal strength value capable of satisfying uplink communication. Then, when both T1 and T2 are greater than T, and both R1 and R2 are less than R, the resonant frequency of the antenna of the control electronics is biased towards the downlink communication band of communication between the electronics and the base station. The second preset intensity value is greater than or equal to the first preset intensity value.
In this embodiment, for how to control the resonance frequency of the antenna of the electronic device to be biased to the downlink communication frequency band for communication between the electronic device and the base station and how to control the resonance frequency of the antenna of the electronic device to be biased to the downlink communication frequency band for communication between the electronic device and the base station, reference may be made to the above description, and details are not repeated here.
Referring to fig. 3, fig. 3 is a flowchart illustrating a control method of an electronic device according to a third embodiment of the present application.
In this embodiment, the control method of the electronic device may include the steps of:
step 301: the method includes detecting an uplink signal strength of communication between the electronic device and the base station at a first predetermined frequency and detecting a downlink signal strength of communication between the electronic device and the base station at a second predetermined frequency.
The processor is matched with the antenna to detect the strength of an uplink signal communicated between the electronic device and the base station according to a first preset frequency and detect the strength of a downlink signal communicated between the electronic device and the base station according to a second preset frequency.
For example, the detection at the first preset frequency may specifically be: and setting a preset detection time point for detecting the strength of the uplink signal within a preset time. The detection according to the second preset frequency may specifically be: and setting a preset detection time point for detecting the downlink signal intensity in a preset time.
Step 302: and when the uplink signal strength is detected to be lower than a first preset strength value for a first preset time, the uplink signal strength is detected to be gradually reduced, and when the downlink signal strength is detected to be higher than a second preset strength value for a second preset time, the resonance frequency of the antenna of the electronic device is controlled to be deviated to an uplink communication frequency band for communication between the electronic device and the base station.
As mentioned above, for example, the number of detection time points set in the predetermined time is two, and the first preset number and the second preset number are both two. The uplink signal strength detected in time sequence twice is respectively T1 and T2. The downlink signal strength of two consecutive detections is R1 and R2 respectively. The first preset intensity value is T, and the second preset intensity value is R. The first preset strength value may be a lowest signal strength value capable of satisfying uplink communication, and the second preset strength value may be a lowest signal strength value capable of satisfying downlink communication. Then, when both T1 and T2 are less than T, T1 is greater than T2, and R1 and R2 are greater than R, the resonant frequency of the antenna of the control electronic device is biased toward an uplink communication band for communication between the electronic device and the base station. The second preset intensity value is greater than or equal to the first preset intensity value.
Step 303: and when the downlink signal strength is detected to be lower than a third preset strength value for a third preset time, the downlink signal strength is detected to be gradually reduced, and when the downlink signal strength is detected to be higher than a fourth preset strength value for a fourth preset time, the resonance frequency of the antenna of the electronic device is controlled to be deviated to a downlink communication frequency band for communication between the electronic device and the base station.
As mentioned above, for example, the number of detection time points set in the predetermined time is two, and the third preset number and the fourth preset number are both two. The uplink signal intensities detected in two consecutive times are respectively T1 and T2, and the downlink signal intensities detected in two consecutive times according to the time sequence are respectively R1 and R2. The third preset intensity value is R and the fourth preset intensity value is T. The third preset strength value may be a lowest signal strength value capable of satisfying downlink communication, and the fourth preset strength value may be a lowest signal strength value capable of satisfying uplink communication. Then, when T1 and T2 are both greater than T, R1 and R2 are both less than R, and R2 is less than R1, the resonant frequency of the antenna of the control electronic device is biased toward the downlink communication band of communication between the electronic device and the base station. The second preset intensity value is greater than or equal to the first preset intensity value.
In this embodiment, for how to control the resonance frequency of the antenna of the electronic device to be biased to the downlink communication frequency band for communication between the electronic device and the base station and how to control the resonance frequency of the antenna of the electronic device to be biased to the downlink communication frequency band for communication between the electronic device and the base station, reference may be made to the above description, and details are not repeated here.
