Description

Antenna tuning method, device and computer readable storage medium

Technical Field

The present invention relates to the field of mobile communications, and in particular, to an antenna tuning method, device and computer-readable storage medium.

Background

In the prior art, with the rapid development of mobile internet technology, the requirement of a user on the network data transmission rate of a terminal device, such as a mobile phone, is also higher and higher. Among them, the Carrier Aggregation (CA) technology is a method for effectively improving the data throughput of the mobile phone. Carrier aggregation, which is one of the key technology points in LTE technology, is to aggregate two or more Carrier units (CCs) together to support a larger transmission bandwidth and improve data transmission efficiency. In the carrier aggregation technology, a primary carrier and at least one secondary carrier are included, a primary cell is a cell operating on a primary carrier frequency band, and a secondary cell is a cell operating on a secondary carrier frequency band.

At present, the mainstream configuration of terminal devices such as mobile phones generally supports multi-mode and multi-frequency, and the requirement on antennas is high, particularly after entering a 5G network, the frequency band supported by the antennas can be from 800M to 5G, and antenna tuning becomes an important channel for improving the performance of the antennas. In a non-CA scenario, an optimal antenna tuning value can be found for each frequency band through the existing technology, however, in a carrier aggregation scenario, when two or three frequency bands operate on the same antenna, for example, two intermediate frequencies of B1+ B3 use the same antenna, in the carrier aggregation scenario, antenna performances of B1 and B3 need to be considered at the same time, and a simple antenna tuning scheme may not be considered with great effort.

At present, in order to solve the above technical problems, two technical solutions are adopted, namely, a set of tuning values which consider the performance of B1 and B3 antennas is preset for a CA scenario, but as a result of the consideration, the performance of B1 and B3 is reduced in the CA scenario compared with the performance of antennas in a non-CA scenario, and secondly, the tuning values follow the tuning values of a main path, but the method cannot exert the optimal performance of a secondary carrier.

Therefore, it can be seen that the tuning scheme in the prior art does not fully consider the difference problem of the respective frequency band signals of the CA in the existing network environment, and the fixed tuning value in the preset form is a conventional technical orientation, and cannot exert the optimal performance of the CA.

Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

Example one

Fig. 3 is a flow chart of a first embodiment of the antenna tuning method of the present invention. A method of antenna tuning, the method comprising:

s1, acquiring a signal parameter of the terminal equipment according to a preset detection period, and judging whether the signal parameter is lower than a preset parameter value;

and S3, calling the target tuning value in the detection period as the tuning value in the carrier aggregation scene.

In this embodiment, first, a signal parameter of a terminal device is obtained according to a preset detection period, and whether the signal parameter is lower than a preset parameter value is judged; then, if the signal parameter is lower than the preset parameter value, determining a corresponding target tuning value according to the difference value of the signal parameters under different antennas; and finally, calling the target tuning value in the detection period as the tuning value in the carrier aggregation scene.

In this embodiment, corresponding optimal tuning values are given in combination with different receiving performance parameters (such as the size of received signal strength, the size of signal-to-noise ratio, and the like, which may represent the receiving performance) of the main carrier and the auxiliary carrier in the downlink CA or the transmitting performance parameters of the uplink CA in an actual network environment, so that the terminal can exert the optimal performance of the CA in different CA scenarios, and provide better internet access rate experience for users.

In another example, the signal strength is taken as the parameter representation for explanation, specifically, first, the signal strength of the frequency band supported by the terminal device in the CA scenario is judged, and if any one of the signal strengths is lower than a preset threshold, the intelligent tuning judgment mode is started, at this time, the CPU is calculated according to the received signal strength, and the tuning value corresponding to the table is called according to the calculated difference. Optionally, in this embodiment, in order to improve the effectiveness of the tuning value, it is considered that the network environment changes in real time, so in this embodiment, a time threshold is defined, if the time threshold is exceeded, the difference is determined again, and the optimal tuning value is called, and this is performed repeatedly in a cycle within the use period, thereby improving the antenna tuning performance of the terminal device.

The method has the advantages that the signal parameters of the terminal equipment are obtained according to the preset detection period, and whether the signal parameters are lower than the preset parameter values is judged; then, if the signal parameter is lower than the preset parameter value, determining a corresponding target tuning value according to the difference value of the signal parameters under different antennas; and finally, calling the target tuning value in the detection period as the tuning value in the carrier aggregation scene.
