[0035] Embodiment 1
[0036] Figure 1 This is a flowchart of a method for testing the performance of radio frequency carrier aggregation provided in the first embodiment of the present disclosure. This embodiment can be applied to the case of testing the performance of radio frequency carrier aggregation. The method can be executed by a test device for radio frequency carrier aggregation performance. The test device for radio frequency carrier aggregation performance can be implemented in the form of hardware and / or software. The test device for radio frequency carrier aggregation performance can be configured in a control device, and the control device includes but is not limited to a computer, a terminal, a server, and other devices with data processing capabilities. Figure 1 As shown, the method includes:
[0037] S110: Acquire a radio frequency carrier group in the device under test, where the radio frequency carrier group includes at least one radio frequency carrier signal.
[0038] In this embodiment, the device under test (DUT) may be a device or component being tested during an electronic test process, and may be a chip, a circuit board, a system, etc. The device under test may include one or more carrier aggregation (CA) bands in the field of wireless communication, and each carrier aggregation band may be regarded as a radio frequency carrier signal. Therefore, a radio frequency carrier group in the device under test may be obtained, and the radio frequency carrier group includes at least one radio frequency carrier signal.
[0039] S120. Randomly match the radio frequency carrier signals in the radio frequency carrier group with the output interfaces in the output interface group to obtain multiple test matching groups; each test matching group includes a radio frequency carrier signal and an output interface.
[0040] Specifically, after obtaining the RF carrier group through the tested device, the RF carrier signal in the RF carrier group and each output interface in the output interface group can be randomly matched, and then multiple test matching groups can be obtained, wherein the output interface group can include at least one output interface, and each test matching group includes an RF carrier signal and an output interface.
[0041] Exemplarily, when randomly matching the RF carrier signal in the RF carrier group and each output interface in the output interface group, the RF carrier signal can be randomly selected from the RF carrier group, and an output interface can be randomly selected from the output interface group, and then matching is performed; the RF carrier signal in the RF carrier group can also be divided into several blocks (such as: it can be divided into several blocks according to the frequency band of the signal), and the output interface of the output interface group can be divided into several blocks (such as: it can be divided into several blocks according to the maximum frequency band that the output interface can transmit), and then the RF carrier group and the output interface group can be randomly matched in the corresponding blocks.
[0042] S130: Based on the test matching group, perform a radio frequency carrier aggregation performance test on the device under test.
[0043] Specifically, after obtaining the test matching group, the RF carrier signal can be transmitted to the matching output interface according to the test matching group to test the RF carrier aggregation performance of the device under test.
[0044] This embodiment provides a method for testing the performance of RF carrier aggregation, including: obtaining a RF carrier group in a device under test, wherein the RF carrier group includes at least one RF carrier signal; randomly matching the RF carrier signals in the RF carrier group with the output interfaces in the output interface group to obtain multiple test matching groups; each of the test matching groups includes an RF carrier signal and an output interface; and based on the test matching groups, testing the performance of RF carrier aggregation of the device under test. This technical solution randomly matches the RF carrier signals in the RF carrier group with the output interfaces in the output interface group, thereby avoiding conflicts caused by channel combinations between different RF carriers and improving test efficiency.
[0045] As an optional implementation manner of this embodiment, the test method for radio frequency carrier aggregation performance provided in this embodiment further includes:
[0046] An output interface group set in the device under test is determined; the output interface group includes at least one output interface; the number of output interfaces in the output interface group is the same as the number of radio frequency carrier signals in the radio frequency carrier group.
[0047] In this embodiment, an output interface group can be determined based on the output interface set in the device under test, and the output interface group includes at least one output interface. Exemplarily, 10 output interfaces are set in the device under test, and the 10 output interfaces can constitute an output interface group. It should be noted that the number of output interfaces in the output interface group is the same as the number of RF carrier signals in the RF carrier group.
[0048] As an optional implementation of this embodiment, the RF carrier group and the output interface group are randomly matched to obtain multiple test matching groups, including:
[0049] 1) In each iteration, randomly selecting one of the radio frequency carrier signals and one of the output interfaces to form a test matching group; the output interface is obtained by randomly selecting from the output interface group;
[0050] Specifically, in each iteration, a radio frequency carrier signal can be randomly selected from the radio frequency carrier group, and an output interface can be randomly selected from the output interface group, and the output interface and the radio frequency carrier signal form a test matching group, and the test matching group includes a radio frequency carrier signal and an output interface.
[0051] 2) updating the radio frequency carrier group based on the radio frequency carrier signal to obtain an updated radio frequency carrier group; wherein the updated radio frequency carrier group does not include the radio frequency carrier signal;
[0052] Specifically, after obtaining the test matching group, the RF carrier group can be updated according to the RF carrier signal in the test matching group, that is, the RF carrier signal in the test matching group can be deleted from the RF carrier group to update the RF carrier group, wherein the updated RF carrier group does not contain the RF carrier signal in the test matching group.
[0053] 3) updating the output interface group based on the output interface to obtain an updated output interface group; wherein the updated output interface group does not include the output interface;
[0054] Specifically, after obtaining the test matching group, the output interface group can be updated according to the output interface in the test matching group, that is, the output interface in the output interface group can be deleted from the output interface group to update the output interface group, wherein the updated output interface group does not include the output interface in the test matching group, thereby avoiding the situation where two RF carrier signals match the same output interface, thereby improving the efficiency of the test.
[0055] Exemplarily, the RF carrier group may include RF carrier signals CA Band1, CA Band2, CA Band3, and CA Band4, and the output signal group may include output interfaces OUT1, OUT2, OUT3, and OUT4. The RF carrier signal CA Band3 is randomly extracted from the RF carrier group, and the output interface OUT1 is randomly extracted from the output signal group. CA Band3 and OUT1 form a test matching pair, and the RF carrier signal CA Band3 is deleted from the RF carrier group, and the output interface OUT1 is deleted from the output signal group, to obtain the updated RF carrier group: CA Band1, CA Band2, and CA Band4, and the updated output signal group: OUT2, OUT3, and OUT4.
[0056] 4) If the current iteration does not meet the iteration stop condition, enter the next iteration;
[0057] Specifically, after the RF carrier group and the output interface group are updated, it can be determined whether the current iteration meets the iteration stop condition. If the current iteration does not meet the iteration stop condition, the next iteration is entered.
[0058] Exemplarily, if there are radio frequency carrier signals in the radio frequency carrier group, it can be considered that not all radio frequency carrier signals in the radio frequency carrier group have corresponding test matching groups, and the next iteration is entered.
[0059] 5) If the current iteration meets the iteration stop condition, the iteration is stopped to obtain multiple test matching groups.
[0060] In this embodiment, if the current iteration satisfies the iteration stop condition, the iteration is stopped, that is, multiple test matching groups can be obtained. Optionally, the iteration stop condition is:
[0061] Any radio frequency carrier signal in the radio frequency carrier group has a corresponding test matching group, and output interfaces in each test matching group are not repeated.
[0062] Exemplarily, the RF carrier signals and output interfaces that have been matched in the RF carrier group and the output interface group are deleted, and then the deleted RF carrier group can be confirmed to see whether there are any RF carrier signals that have not been matched, and whether there are duplicate output interfaces in the obtained test matching group. If there are no RF carrier signals in the RF carrier group, it can be considered that the RF carrier signals in the RF carrier group all have corresponding test matching groups, and the iteration is stopped when it is determined that the output interfaces in each test matching group are not duplicated.
[0063] Figure 2 A process diagram of a method for testing radio frequency carrier aggregation performance provided in this embodiment, such as Figure 2 As shown, a radio frequency carrier signal is randomly selected from the radio frequency carrier group, an output interface is randomly selected from the output interface group, and the radio frequency carrier signal and the output interface are combined into a test matching group; the radio frequency carrier group and the output interface group are updated using the radio frequency carrier signal and the output interface in the test matching group, and then it is determined whether the current iteration meets the iteration stop condition, if it meets the condition, the iteration is stopped, and if it does not meet the condition, the next iteration is entered. This avoids the conflict between channel combinations of different radio frequency carriers and improves the test efficiency.
