Description

Technical Field

[0001] The present disclosure relates to the technical field of terminal equipment calibration, and in particular to a method and device for automatic port identification for terminal radio frequency calibration. Background Art

[0002] During the design and production of terminal products, in order to eliminate the impact of factors such as device inconsistency, temperature changes and device aging, each terminal device needs to be calibrated for RF. During the calibration process, the data that needs to be compensated and corrected is measured, calculated and saved in the corresponding calibration parameters to ensure that its RF performance meets the basic requirements of the test.

[0003] RF calibration requires the terminal to be connected to the RF tester through an RF cable. The selection of the RF port needs to be manually determined and written into the calibration parameters, which is very troublesome to modify and transfer. Especially in the 5G NR system, due to the introduction of large-scale MIMO, each frequency band needs to be configured with up to 6 channels, and each channel requires a separate instrument port. Especially in the production line, the same calibration environment is often used for different projects, and the selection of RF ports between different projects is often different, which requires production line workers to repeatedly change RF ports, causing great inconvenience. Therefore, a terminal RF calibration method with automatic port identification for terminal RF calibration is needed to solve the above problems. Summary of the invention

[0047] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0048] Figure 1 FIG. 1 is a schematic diagram of a common calibration system in the prior art. Figure 1 As shown, the hardware structure of the calibration system includes an RF comprehensive tester, a terminal device to be tested, and a PC, wherein the RF comprehensive tester and the terminal device to be tested are connected by an RF line, and the PC controls the RF comprehensive tester and the terminal device to be tested through a data line.

[0049] Figure 2 This is a calibration flow chart of a common calibration system in the prior art. Figure 2 In the calibration flow chart shown, the order of steps 1 to 4 is basically fixed, while the steps after step 5 can be adjusted, each of which can be checked separately as needed, and the selection of the instrument port is often written into the calibration parameters and read in the second step of the calibration process.

[0050] The common calibration system in the prior art implements the calibration process by writing the instrument port selection of each channel of each frequency band into the calibration parameters, which are then called during the calibration process.

[0051] Figure 3 The following is an example diagram of the N78 band port selection in a common calibration system in the prior art. Figure 3 Among the common N78 frequency band ports shown in the figure, N78 supports 2T4R (two-way transmission and four-way reception including TX / TXMIMO / PRX / PRXMIMO / DRX / DRXMIMO, a total of six channels). Figure 3 The information in the table is saved in the corresponding calibration parameters to specify the instrument port to be used for each channel.

[0052] The disadvantages or problems of the common calibration systems in the above-mentioned prior art are that the selection of RF ports needs to be manually determined and written into the calibration parameters, which is very troublesome to modify and transmit. Especially in the 5G NR system, due to the introduction of large-scale MIMO, each frequency band needs to be configured with up to 6 channels, and each channel needs to have a separate instrument port. Especially in the production line, the same calibration environment is often used for different projects, and the selection of RF ports between different projects is often different, which requires production line workers to repeatedly change RF ports, which is very inefficient.

[0053] Figure 4 The calibration flow chart of the calibration system provided in the embodiment of the present disclosure is as follows. Figure 4 As shown, in the present disclosure, an optional port automatic identification step for terminal RF calibration is added to the RF calibration process. This step performs non-signaling tests on each signal path in each frequency band and traverses each port of the RF comprehensive tester. When the used port is tested, the result is saved in the calibration parameter.
