It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. 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.

Before describing the present invention, technical terms that may be referred to in the present application will be described first.

A radio frequency module, also referred to as a radio frequency circuit, may be used to connect the antenna to one or more antennas. Optionally, the rf module includes, but is not limited to, a filter, a Low Noise Amplifier (LNA), an analog-to-digital/digital-to-analog (a/D or D/a) converter, and the like.

Frequency bands and channels, both used to represent spectrum resources. A frequency band typically includes multiple channels. For example, a 2.4 gigahertz (GHz) frequency band may include 14 channels.

The radio frequency channel is a channel for signal transceiving, which includes an antenna and a radio frequency module, and one antenna corresponds to one radio frequency channel in the signal transceiving process.

A wireless device, a User Equipment (UE) with wireless connection function, wherein the wireless connection includes a bluetooth connection, an infrared connection, a Wi-Fi connection, etc., and the wireless device may be a mobile terminal device, examples of which include but are not limited to a satellite or a cellular phone; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. The wireless device may also be a wireless Access Point (AP) in a wireless local area network. In an embodiment of the present application, the wireless device may include at least one radio frequency module, and each radio frequency module may be connected to one or more antennas.

The radio frequency calibration means that a software parameter method is used for compensating radio frequency parameter deviation caused by hardware consistency deviation. In one embodiment, the MTK software provides a data structure (corresponding to cal. ini files) and a calibration software tool ATE that may be used to store the radio frequency calibration parameters. The wireless device, such as a smart phone, may invoke these calibrated parameters to optimize the performance of the radio frequency while the actual network is operating.

First embodiment

Referring to fig. 1, the radio frequency calibration method provided in this embodiment is applied to a wireless device, and includes the following steps.

Step S101, obtaining environmental parameters of the current environment.

In this embodiment, the environmental parameters of the current environment include, but are not limited to, indexes of a natural environment and indexes of a network environment, for example, the environmental parameters may be a temperature of the current environment, channel information for establishing a wireless connection, and the number of routers, for example, the current environmental temperature is 40 degrees celsius, the wireless connection is established with the 6 th channel, and the number of routers is 20. In other embodiments, the current environmental parameters may also include other environmental parameters that affect radio frequency performance, such as ambient humidity, signal strength of the respective router, and the like. The current environment parameters include parameters related to the natural environment, such as temperature, humidity, wind power, etc., and parameters related to the configuration environment, such as the number of routers in the wireless local area network, the signal strength of each router, etc.

The acquisition of the environmental parameters can be achieved through an acquisition module, the acquisition module is arranged in the wireless device, and the acquisition module specifically comprises a temperature and humidity sensor, a signal detection module and the like.

Step S102, determining whether a variation of the environmental parameter of the current environment with respect to the environmental parameter of the previous environment is greater than a preset threshold.

The environmental parameter of the previous environment may be a stored environmental parameter, where the stored environmental parameter refers to an environmental parameter that is built in a data structure of a memory of the wireless device, and the stored environmental parameter may be a factory value that has not been recalibrated, or an environmental parameter corresponding to the previous wireless connection, or in short, an environmental parameter that has been stored in the wireless device, for example, the stored environmental parameter indicates that in the wireless connection environment at that time, the environmental temperature is 20 degrees celsius, and the number of routers is 10.

The environmental parameter of the previous environment may also be the environmental parameter corresponding to the last time the wireless connection was established.

The environmental parameter of the previous environment may also be the environmental parameter corresponding to each calibration of the rf parameter historically.

And comparing the environmental parameters of the current environment with the environmental parameters of the previous environment, and calculating the variable quantity. The preset threshold value is a limit value which needs to be subjected to radio frequency calibration again after the test. The preset threshold may include various kinds of limits, for example, the preset threshold is: the amount of change in the ambient temperature of the current environment at the time of wireless connection establishment from the ambient temperature of the previous environment is equal to or greater than 20 degrees celsius; the preset threshold may also be: the number of routes in the current channel of the established wireless connection is equal to or more than 10 in comparison with the number of routes in the same previous channel; the preset threshold may also be: the amount of change in the environmental humidity of the current environment at the time of wireless connection establishment from the environmental humidity of the previous environment is equal to or greater than 30 grams/cubic meter, or the like. The preset threshold may also be: the channel information is different from the previous channel.

The specific limit value of the preset threshold value can be adjusted according to the actual test condition, the setting of the preset threshold value needs to be balanced, namely the preset threshold value cannot be too low, so that the wireless equipment needs to frequently carry out frequency calibration, and cannot be too high, so that the dynamic frequency calibration loses significance, and on the premise, the setting of the preset threshold value can play a role in adaptively and dynamically adjusting along with the change of the current environment.

Meanwhile, the determination condition may be further preset such that, when the variation satisfies any one of the above-mentioned various limit values, the determination result is yes, that is, it is determined that the variation of the current environmental parameter from the environmental parameter of the previous environment is greater than the preset threshold.

In addition, the determination condition may be preset such that, when the amount of change satisfies all of the above-mentioned various kinds of limit values, it is determined that the amount of change of the current environmental parameter from the environmental parameter of the previous environment is greater than the preset threshold as a yes result.

When comparing, according to actual need, the parameters of the current environment can be compared with the previous environment parameters only, or compared with each recorded environment parameter one by one.

Step S103, when the variation is larger than the preset threshold, the radio frequency parameter is recalibrated.

After the determination in step S102, if the determination result is "greater than", the rf parameters are recalibrated. Aspects of calibration include, but are not limited to: AFC calibration (Auto Frequency Control), RXLEV calibration (receiver calibration), APC calibration (Automatic Phase Control, transmitter Automatic gain Control voltage calibration), and the like.

The current environment parameters can be recorded and stored in the historical environment database when recalibration is performed. In other embodiments, the rf parameter and the rf calibration parameter may be data in two data results, so that the updated rf calibration parameter may be obtained according to the current environment parameter, and then the rf parameter is calibrated by the rf calibration parameter.

The processor of the wireless device adjusts the hardware performance of the radio frequency module according to the calibrated radio frequency parameters, so as to obtain better (for example, faster and more stable signal transmission) signal transmission performance in the wireless connection process, and improve user experience.

No matter which of the specific judgment conditions is, when the judgment result is equal to or less than the preset threshold, the variation of the current environmental parameter relative to the environmental parameter of the previous environment is considered to be not more than the preset threshold, and the frequency parameter does not need to be recalibrated and can be directly applied.

In summary, the rf calibration method provided in this embodiment compares the environmental parameter of the current environment with the environmental parameter of the previous environment to determine whether the environmental parameter is greater than the preset threshold, and if so, calibrates the rf parameter, thereby achieving the purpose of dynamically adjusting the rf parameter along with the environmental change to obtain better wireless signal transmission performance.

Second embodiment

Referring to fig. 2, the radio frequency calibration method provided in this embodiment includes the following steps.

Step S201, recording the environmental parameters corresponding to the radio frequency parameters of each calibration, and constructing a historical environmental database.

When the radio frequency parameters need to be recalibrated, the fact that the variation between the current environmental parameters and the environmental parameters of the previous environment is larger than the threshold value means that the current environmental parameters and the environmental parameters of the previous environment are different, therefore, recording can be carried out, and a historical environmental database can be constructed for access. Correspondingly, the historical environment database also records the corresponding radio frequency parameters.

For example, in one embodiment, when a wireless connection is previously established, there are typically multiple channels available for selection, e.g., the 2.4 gigahertz (GHz) band includes 14 channels in total, and typically, the wireless device will automatically select channel 6 because its adjacent channel interference is typically minimal. Therefore, the environment parameters of the previous environment at least include one or more of channel information of the 6 th channel, environment temperature, number of routers, or other relevant environment parameters. However, in the current wireless connection, the wireless device establishes a wireless connection with the 1 st channel, and compared with the environmental parameters of the previous environment, the radio frequency parameters are recalibrated because the channel is switched, the variation is determined to be larger than the preset threshold, or the temperature variation is determined to be larger than the threshold, and so on. Accordingly, the current environmental parameter is recorded as an environmental parameter at which an RF recalibration event occurred as part of the historical environmental database.

Step S202, obtaining the environmental parameters of the current environment.

In step S203, it is determined whether the variation of the environmental parameter of the current environment relative to the environmental parameter of the previous environment is greater than a preset threshold.

In step S204, when the variation is greater than the preset threshold, the rf parameters are recalibrated.

Step S201 may be the first step or the last step in this embodiment, and the implementation order is not limited by the numbering order.

The description of the other steps in this embodiment may refer to the description of the same steps in the first embodiment.

In summary, in the embodiment, by establishing the historical environment database, all the environment parameters that cause the recalibration of the rf parameters can be recorded, so that a basis is provided for improving the calibration reliability of the rf parameters. Meanwhile, the radio frequency calibration method provided by the embodiment judges whether the environmental parameter of the current environment is greater than the preset threshold value by comparing the environmental parameter of the current environment with the environmental parameter of the previous environment, and calibrates the radio frequency parameter if the environmental parameter of the current environment is greater than the preset threshold value, so that the radio frequency parameter is dynamically adjusted along with the change of the environment, and the purpose of obtaining better wireless signal transmission performance is achieved.

Third embodiment

Referring to fig. 3, in the present embodiment, based on the second embodiment, the step S202 further includes the following steps.

In step S2021, it is determined whether or not the same history environment as the current environment exists in the history environment database.

Step S2022, when the historical environment identical to the current environment is not found in the historical environment database, acquiring the environmental parameters of the current environment.

That is to say, when a certain calibrated important environment parameter (for example, channel information) of the current environment does not appear, assuming that it is the 14 th channel that is currently establishing wireless connection, and no environment parameter that establishes connection with the 14 th channel has appeared in the previously recorded historical environment, the environment parameter of the current environment is obtained, which includes at least one of the environment temperature, the number of routes, and the like, in addition to the channel information.

For another example, when a certain calibrated important environmental parameter (e.g., temperature information) of the current environment does not appear, assuming that the current environmental temperature is 42 degrees celsius through testing, and no environmental parameter related to 42 degrees celsius appears in the previously recorded historical environment, the environmental parameter of the current environment is obtained, and the environmental parameter includes at least one of channel information, routing number, and the like in addition to the environmental information.

Specifically, in step S2021, determining whether the same historical environment as the current environment exists in the historical environment database may further include:

acquiring identification information of a current environment; and judging whether the historical environments have the same identification information in the historical environment database or not based on the identification information of the current environment.

The identification information appears as a mark, for example, when the 1 st channel in the environment of the current environment is marked as 0, the environment temperature is marked as 1 within the range of 20 to 30 degrees, the number of routes is marked as 2 within 3, and the environment identification information is marked as 012. The data in the historical environment database establishes identification information according to the same identification rule, and when the identification information is the same, the current environment and the historical environment are the same or fall into the same range, and the corresponding radio frequency parameters can be the same. Therefore, when the historical environment which is the same as the current environment is found in the historical environment database, the radio frequency parameters are adjusted to the radio frequency parameters corresponding to the historical environment. When the identification information is different, for example, the identification information of the historical environment is 013, 103, 112, etc., it indicates that the same environmental parameter does not exist in the historical environment database, so that the specific environmental parameter of the current environment can be obtained, and the radio frequency calibration is performed when the variation is greater than the threshold. If the variation is less than or equal to the threshold, although there is a change, the radio frequency parameters are maintained.

Further, when the historical environment which is the same as the current environment is found in the historical environment database, the radio frequency parameters are adjusted to the radio frequency parameters corresponding to the historical environment, and the radio frequency parameters are directly calibrated.

In summary, the radio frequency calibration method provided in this embodiment compares the established historical environment database with the environment parameters of the current environment, and when the same environment parameters exist, the corresponding radio frequency parameters can be directly used, and when the same environment parameters do not exist, specific environment parameters are obtained to be compared with the environment parameters of the previous environment, so as to determine whether calibration is needed, thereby achieving the purpose of dynamically adjusting the radio frequency parameters along with the change of the environment to obtain better wireless signal transmission performance.

Fourth embodiment

Referring to fig. 4, the rf calibration apparatus 40 of the present embodiment includes an obtaining module 41, a determining module 42, and a calibrating module 43.

The obtaining module 41 is configured to obtain an environmental parameter of a current environment.

The determining module 42 is configured to determine whether a variation of the environmental parameter of the current environment from the environmental parameter of the previous environment is greater than a preset threshold.

The calibration module 43 is configured to recalibrate the rf parameter when the variation is larger than a preset threshold.

In summary, the rf calibration apparatus provided in this embodiment compares the environmental parameter of the current environment with the environmental parameter of the previous environment to determine whether the environmental parameter is greater than the preset threshold, and if the environmental parameter is greater than the preset threshold, the rf calibration apparatus calibrates the rf parameter, thereby dynamically adjusting the rf parameter along with the environmental change to obtain better wireless signal transmission performance.
