Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
As shown in fig. 1, an embodiment of the present invention provides a power compensation method applied to an electronic device with multiple antennas, including:
and step 11, under the condition that the target antenna is in a working state, obtaining the working frequency bands of other antennas except the target antenna in the plurality of antennas at intervals of a first preset time.
Specifically, under the condition that the path of the target antenna is in the working state of information transmission, the working states of other antennas, that is, the working frequency bands of the other antennas, are periodically monitored at intervals of a first preset duration (the time for periodically monitoring the states of the antennas can be adjusted as needed), where the other antennas may affect the antenna efficiency of the target antenna in different working frequency band states. For example: as shown in fig. 2, the first antenna 1 is a target antenna, and the second antenna 2 and the third antenna 3 are other antennas.
Specifically, when a first time node is located, the working frequency bands of other antennas are obtained, and a first target antenna efficiency of the first time node is determined according to the corresponding relation; and when a second time node which is at least one first preset time length away from the first time node is obtained, obtaining the working frequency bands of other antennas, determining a second target antenna efficiency of the second time node according to the corresponding relation, and obtaining a difference value between the first target antenna efficiency of the first time node and the second target antenna efficiency of the second time node, namely a first difference value, wherein the first difference value is greater than or equal to 0.
Specifically, the related information that the other antennas affect the antenna efficiency of the target antenna may be entered in the electronic device in advance, that is, a corresponding relationship between different working frequency bands of the other antennas and the target antenna efficiency is established. The table of the correspondence is as follows:
| target antenna efficiency | Second antenna | Third antenna | … |
| -6dB | B8 frequency band | n41 frequency band | … |
| -4dB | B5 frequency band | n41 frequency band | … |
| -5.5dB | B8 frequency band | n78 frequency band | … |
| -8dB | B5 frequency band | n78 frequency band | … |
| … | … | … | … |
When the second antenna is in a B8 frequency band and the third antenna is in an n41 frequency band, the corresponding target antenna efficiency is-6 dB; when the second antenna is in the B5 frequency band and the third antenna is in the n41 frequency band, the corresponding target antenna efficiency is-4 dB; when the second antenna is in the B8 frequency band and the third antenna is in the n78 frequency band, the corresponding target antenna efficiency is-5.5 dB; when the second antenna is in the B5 frequency band and the third antenna is in the n78 frequency band, the corresponding target antenna efficiency is-8 dB.
And step 13, performing power compensation on the conducted transmitting power or the conducted receiving power of the target antenna between the first time node and the second time node under the condition that the first difference is larger than a preset threshold value.
Specifically, if the first difference is greater than a preset threshold, performing power compensation on the conducted transmission power or the conducted reception power of the target antenna between the first time node and the second time node; if the absolute value of the first difference is less than or equal to the preset threshold, the conducted transmitting power or the conducted receiving power of the target antenna does not need to be adjusted. The preset threshold is a limit value for judging whether other antennas have a large influence on the target antenna efficiency, and if the first difference is larger than the preset threshold, the target antenna efficiency at the second time node is poor, and the signal quality is also poor.
In the above embodiment of the present invention, a first difference between a first target antenna efficiency and a second target antenna efficiency is obtained according to a corresponding relationship between different working frequency bands of other antennas and the target antenna efficiency, and power compensation is performed on conducted transmit power or conducted receive power of the target antenna between the first time node and the second time node when the first difference is greater than a preset threshold, so as to effectively solve a problem of antenna performance degradation caused by mutual coupling among multiple antennas in the same electronic device, and improve communication quality.
Optionally, step 13 may specifically include:
determining a target power compensation value according to the first difference value and the preset threshold value;
and according to the target compensation value, performing power compensation on the conducted transmitting power or the conducted receiving power of the target antenna between the first time node and the second time node.
Specifically, a compensation value required for power compensation, that is, a target power compensation value, is determined according to a magnitude relationship between the first difference and the preset threshold and a difference between the first difference and the preset threshold, and power compensation for conducted transmission power or conducted reception power of the target antenna is completed between the first time node and the second time node.
Optionally, the target power compensation value is greater than or equal to a second difference between the preset threshold and the first difference, and the target power compensation value is less than or equal to the first difference.
Specifically, the second difference is a difference between the first difference and a preset threshold, and the second difference is greater than or equal to 0. And under the condition that the target power compensation value is the first difference value, the power compensation is carried out on the conducted transmitting power or the conducted receiving power of the target antenna, so that the effects of keeping the output power of the whole machine unchanged and the like can be achieved, and the communication quality is improved.
Further, the performing power compensation on the conducted transmission power or the conducted reception power of the target antenna between the first time node and the second time node according to the target power compensation value may specifically include:
determining a second time length according to the target power compensation value, wherein the second time length is the time length for performing power compensation on the conducted transmitting power or the conducted receiving power of the target antenna;
determining a third time node between the first time node and the second time node according to the second time length, wherein the third time node is an initial time node for performing power compensation;
completing power compensation for conducted transmit power or conducted receive power of the target antenna between the third time node and the second time node.
Specifically, after the power compensation is completed, the operating frequency bands of other antennas are continuously monitored.
Optionally, the time from the third time node to the second time node is at least the second duration.
Specifically, according to the target power compensation value, a second time length required for completing power compensation of the target power compensation value is obtained, and according to the second time length, the time for starting power compensation can be determined as a third time node, that is, the power compensation is started at least in advance of the time of the second time length, so that the power compensation is completed before the target antenna efficiency is deteriorated, the time for closed-loop power control is skipped, and the time period with poor signal quality is avoided in advance, thereby improving the communication quality.
The above method is explained in detail by a specific example below:
assuming that a minimum time component of the electronic device is t, periodically monitoring working frequency bands of other antennas (such as a second antenna and a third antenna) at intervals of a first preset time (such as n times of t), recording the working frequency bands of the other antennas of a first time node (namely a current time node), monitoring the working frequency bands of the other antennas of a second time node (namely a next time node), obtaining a first target antenna efficiency of the first time node and a second target antenna efficiency of the second time node, and obtaining a first difference M between the target antenna efficiencies of the two time nodes, wherein if M is greater than a preset threshold value M, power compensation needs to be performed on conducted transmitting power or conducted receiving power of the target antenna between the first time node and the second time node.
For example: the preset threshold value M is 3, when the first time node is reached, the working frequency band of the second antenna is a B5 frequency band, the working frequency band of the third antenna is an n41 frequency band, and the efficiency of the first target antenna is-4 dB; when the second time node is detected, the working frequency band of the second antenna is the B5 frequency band and is unchanged, and the working frequency band of the third antenna is switched from the n41 frequency band to the n78 frequency band, so that the efficiency of the second target antenna becomes-8 dB; then
m＝|-8-(-4)|＝|-4dB|＝4dB
Namely, it is determined that the second target antenna efficiency is decreased by 4dB compared to the first target antenna efficiency, and exceeds the preset threshold, power compensation needs to be performed on the conducted transmitting power or the conducted receiving power of the target antenna at a third time node in advance, a target power compensation value for performing power compensation is greater than or equal to 1dB, and the target power compensation value is less than or equal to 4 dB.
As shown in fig. 3, in the target antenna timing chart, when n is 10 and the target power compensation value is 4dB, the first target antenna efficiency of the target antenna at the time point of 10 × t0 is-4 dB, the second target antenna efficiency at the time point of 20 × t0 is-8 dB, and if the time required for completing the power compensation of 4dB is 3 × t0, it is necessary to start the power compensation at least 3 × t0 ahead, that is, at the latest, it is necessary to start the power compensation at the time point of 17 × t0, so as to ensure that the power compensation is completed at the time point of 20 × t0, so that the power emitted by the whole machine at the time point of 20 × t0 is kept unchanged, and the communication efficiency is improved.
In summary, the embodiments of the present invention can perform power compensation on the conducted transmitting power or the conducted receiving power of the target antenna in advance without changing hardware, so as to improve the problem of antenna performance degradation caused by antenna mutual coupling (e.g., the problem of stutter caused by sudden degradation of bluetooth antenna performance when a bluetooth headset is used to listen to music).
