Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The flow diagrams depicted in the figures are merely illustrative and not necessarily all of the elements and operations/steps are included or performed in the order described. For example, some operations/steps may be further divided, combined, or combined, so that the order of actual execution may be changed according to actual situations.
As shown in fig. 1, fig. 1 is a flowchart of a method for adjusting isolation of an antenna according to an embodiment of the present application, where the method includes the following steps:
step S101, obtaining signal strength corresponding to a signal transmitted by at least one second antenna received by the first antenna.
The embodiment is applied to a terminal, wherein the terminal comprises, but is not limited to, a smart phone, a tablet computer, a notebook computer, a smart watch and other devices with communication functions. The terminal is provided with a first antenna and at least one second antenna, and the wireless communication function is realized through the first antenna, the at least one second antenna and other circuit modules. Illustratively, the first antenna is a TRX (Transceiver) antenna of N41 and the second antenna is a MIMO (multiple-in multiple-out) antenna of N41.
When the terminal works in SRS (Sounding Reference Signal, channel sounding reference signal), the first antenna transmits signals to poll other antennas, and when the second antenna is polled, the first antenna receives signals transmitted by the second antenna, and the signal strength corresponding to the signals is obtained.
Illustratively, when the first antenna transmits a signal to poll the second antenna, the backward coupling function of the coupler of the terminal is opened, and the signal strength of the signal transmitted by the second antenna and received by the first antenna is obtained through the power coupling circuit.
Step S102, according to the signal intensity, an adjustable decoupling network and an antenna matching network are adjusted to improve the isolation between the first antenna and the at least one second antenna.
After the signal intensity corresponding to the signal transmitted by the second antenna and received by the first antenna is obtained, the isolation condition of the first antenna and the second antenna can be obtained according to the signal intensity, at this time, the signal intensity of the signal transmitted by the second antenna and received by the first antenna is reduced while the normal wireless communication performance of the terminal is ensured by adjusting the adjustable decoupling network and the antenna matching network, and the isolation between the first antenna and at least one second antenna is improved.
By adjusting the adjustable decoupling network and the antenna matching network, the signal strength of the signal transmitted by the second antenna received by the first antenna is minimized while the normal wireless communication performance of the terminal is ensured, so that the isolation between the first antenna and the at least one second antenna is maximized.
In an embodiment, adjusting the tunable decoupling network and the antenna matching network may include: and adjusting the capacitance and/or resistance of the corresponding circuits of the adjustable decoupling network and the antenna matching network so as to improve the isolation between the first antenna and the at least one second antenna.
For example, the capacitances of the corresponding circuits of the tunable decoupling network and the antenna matching network are adjusted. For example, if the capacitance is increased, and then the signal strength corresponding to the signal transmitted by the second antenna and received by the first antenna is increased, that is, the isolation between the first antenna and the second antenna is reduced, it is not feasible to increase the capacitance, and at this time, an adjustment operation for reducing the capacitance is performed. Through repeated iterative adjustment operation, the isolation between the first antenna and the second antenna is improved, for example, the isolation between the first antenna and the second antenna is maximized.
By adjusting the adjustable decoupling network and the antenna matching network, the isolation between the first antenna and at least one second antenna is improved on the premise of not increasing hardware cost, so that the wireless performance of the terminal is improved.
In an embodiment, as shown in fig. 2, step S101 may be followed by steps S103 to S105.
Step S103, judging whether the antenna state reaches a preset optimal state according to the signal intensity; if yes, go to step S104; if not, executing step S105;
step S104, ending the operation;
step S105, adjusting the adjustable decoupling network and the antenna matching network.
Exemplary, the antenna state reaching the preset optimal state includes: the RSRP (Reference Signal Receiving Power, reference signal received power) value of the first antenna is greater than or equal to a preset RSRP threshold, and the signal strength reaches a first signal strength, wherein the first signal strength is a minimum signal strength for ensuring normal wireless communication performance; or the signal strength reaches a second signal strength, wherein the second signal strength is the minimum signal strength of the received signal.
After the signal intensity corresponding to the signal transmitted by the second antenna and received by the first antenna is obtained, based on the signal intensity, judging whether the state of the antenna at the moment enables the antenna performance to be optimal according to different judging strategies.
For example, the judgment policy takes into account the isolation between the first antenna and the second antenna and the receiving performance of the first antenna, such as RSRP. Because the adjustable decoupling network not only affects the isolation between the first antenna and the second antenna, but also affects the performance of the first antenna, the judgment policy may be to use the signal strength to reach the minimum signal strength that can ensure the normal wireless communication performance (the RSRP value of the first antenna is greater than or equal to the preset RSRP threshold) as the judgment standard that reaches the optimal state, that is, use the RSRP value of the first antenna is greater than or equal to the preset RSRP threshold, and use the signal strength to reach the judgment standard that the first signal strength reaches the optimal state as the antenna state, under the judgment standard, the performance of the first antenna is not greatly affected while the isolation between the first antenna and the second antenna is improved.
For another example, the judging strategy only considers the isolation between the first antenna and the second antenna, and does not consider the receiving performance of the first antenna. For the case that the circuit behind the second antenna is directly connected with an external LNA (low noise amplifier ) module, if the isolation between the first antenna and the second antenna is small, the signal intensity corresponding to the signal transmitted by the second antenna received by the first antenna is relatively strong, and then the LNA module on the second antenna path is likely to be burnt out. In order to avoid this, the judgment policy may directly use the signal strength to reach the minimum as the judgment criterion for the antenna state to reach the optimum state, that is, use the signal strength to reach the second signal strength as the judgment criterion for the antenna state to reach the optimum state.
If the antenna state reaches the preset optimal state, the isolation between the first antenna and the second antenna does not need to be adjusted, and at the moment, the operation is ended, and the first antenna and the second antenna communicate based on the current isolation.
If the antenna state does not reach the preset optimal state, at the moment, the adjustable decoupling network and the antenna matching network are adjusted, and the isolation between the first antenna and the second antenna is improved.
In an embodiment, to ensure that the antenna state is optimal, after adjusting the tunable decoupling network and the antenna matching network, it may include: detecting the signal intensity corresponding to the latest signal transmitted by the second antenna after adjustment; and if the signal intensity corresponding to the latest signal transmitted by the second antenna is greater than the second signal intensity, returning to the step of adjusting the adjustable decoupling network and the antenna matching network until the signal intensity corresponding to the latest signal transmitted by the second antenna reaches the second signal intensity.
Under the situation that the judgment strategy only considers the isolation between the first antenna and the second antenna, after the operation of adjusting the adjustable decoupling network and the antenna matching network is carried out once, detecting the signal intensity corresponding to the latest signal transmitted by the second antenna received by the first antenna after adjustment, if the signal intensity corresponding to the latest signal transmitted by the second antenna received by the first antenna is greater than the second signal intensity, that is, the antenna state is not optimal, the isolation between the first antenna and the second antenna can be improved, at the moment, continuously adjusting the adjustable decoupling network and the antenna matching network, detecting the signal intensity corresponding to the latest signal transmitted by the second antenna received by the first antenna after adjustment again, judging whether the signal intensity is greater than the second signal intensity, and cycling the operation until the signal intensity corresponding to the latest signal transmitted by the second antenna received by the first antenna after adjustment reaches the second signal intensity, that is minimum, at the moment, ending the operation.
In another embodiment, after adjusting the tunable decoupling network and the antenna matching network, it may include: detecting the RSRP value of the first antenna after adjustment and the signal strength corresponding to the latest signal transmitted by the second antenna; and if the signal intensity corresponding to the latest signal transmitted by the second antenna is greater than the first signal intensity, returning to the step of adjusting the adjustable decoupling network and the antenna matching network until the RSRP value of the first antenna is greater than or equal to the preset RSRP threshold and the signal intensity corresponding to the latest signal transmitted by the second antenna reaches the first signal intensity.
Under the situation that the judgment strategy gives consideration to the isolation between the first antenna and the second antenna and the receiving performance of the first antenna, after each time of operation of adjusting the adjustable decoupling network and the antenna matching network is executed, detecting the signal intensity corresponding to the latest signal transmitted by the second antenna and received by the first antenna after adjustment, and the RSRP value of the first antenna after adjustment, if the signal intensity corresponding to the latest signal transmitted by the second antenna and received by the first antenna is larger than the first signal intensity, that is, the antenna state does not reach the best, the isolation between the first antenna and the second antenna can be improved, at the moment, continuously adjusting the adjustable decoupling network and the antenna matching network, detecting the signal intensity corresponding to the latest signal transmitted by the second antenna and received by the first antenna after adjustment again, and circulating the operation until the signal intensity corresponding to the latest signal transmitted by the second antenna and received by the first antenna after adjustment reaches the first signal intensity, that can ensure the normal minimum signal intensity of wireless communication performance, and end the operation.
In an embodiment, if the second antenna of the terminal includes a plurality of antennas, as shown in fig. 3, step S101 may include sub-step S1011, and step S1011 may include steps S106 to S107.
Step S1011, obtaining a signal strength corresponding to a signal transmitted by each second antenna received by the first antenna.
For example, if the second antennas include N, signal strengths corresponding to signals transmitted by the N second antennas received by the first antenna are obtained.
For example, obtaining the signal strength corresponding to the signal transmitted by each of the second antennas received by the first antenna may include: and when the terminal is in an SRS working state, the first antenna transmits signals to poll a plurality of second antennas, and the signal intensity corresponding to the signals transmitted by each second antenna is obtained.
When the terminal works in SRS, the first antenna transmits signals to all the second antennas, and when one of the second antennas is polled, the signal strength corresponding to the signals transmitted by the second antennas and received by the first antenna is obtained.
And S106, determining the isolation degree of the first antenna and each second antenna according to the acquired signal intensity.
The signal intensities corresponding to the signals transmitted by the second antennas received by the first antennas are different, and accordingly, the isolation between the first antennas and the second antennas is also different. The larger the signal intensity corresponding to the signal transmitted by the second antenna received by the first antenna, the smaller the isolation between the first antenna and the second antenna correspondingly.
And S107, selecting at least one second antenna from the plurality of second antennas according to the isolation degree corresponding to each second antenna, and determining the selected second antenna as the current working antenna, wherein the isolation degree corresponding to the selected second antenna is larger than the isolation degree corresponding to the unselected second antenna.
According to the isolation between the first antenna and each second antenna, 1 or more than 1 second antennas with large isolation between the first antennas are selected from the plurality of second antennas of the terminal to be used as current working antennas, and the rest other unselected antennas are idle and do not work currently.
For example, if the terminal includes N second antennas, according to the isolation between the N second antennas and the first antenna, selecting M second antennas with large isolation between the N second antennas and the first antenna, and determining the second antennas as the current working antennas.
In an embodiment, as shown in fig. 4, step S1011 may be followed by steps S108 to S109.
And S108, adjusting the adjustable decoupling network and the antenna matching network according to the acquired signal intensity, and improving the isolation between the first antenna and each second antenna.
In order to further optimize the antenna state, after the signal intensity corresponding to the signal transmitted by each second antenna received by the first antenna is obtained, the adjustable decoupling network and the antenna matching network are adjusted based on the obtained signal intensity corresponding to the signal transmitted by each second antenna received by the first antenna, so that the isolation between the first antenna and each second antenna is improved while the normal wireless communication performance of the terminal is ensured.
By adjusting the adjustable decoupling network and the antenna matching network, the signal strength of the signal transmitted by each second antenna received by the first antenna is minimized while the normal wireless communication performance of the terminal is ensured, so that the isolation between the first antenna and each second antenna is maximized.
Step S109, selecting at least one second antenna from the plurality of second antennas according to the lifted isolation degree corresponding to each second antenna, and determining the at least one second antenna as the current working antenna.
And selecting 1 or more than 1 second antennas with large isolation degree after lifting from the first antennas from the plurality of second antennas of the terminal based on the isolation degree after lifting from the first antennas to each second antenna, and taking the second antennas with large isolation degree after lifting from the first antennas as current working antennas, wherein the rest other unselected antennas are idle and do not work currently.
In the above description, by acquiring the signal strength corresponding to the signal transmitted by the at least one second antenna received by the first antenna, and then adjusting the adjustable decoupling network and the antenna matching network according to the acquired signal strength, the isolation between the first antenna and the at least one second antenna is improved without increasing the hardware cost, thereby improving the wireless performance of the terminal.
