Description

Technical Field

[0001] This invention relates to the field of communication equipment performance testing technology, and more particularly to a method and apparatus for testing the switching performance of wireless terminal transmitting antennas. Background Technology

[0002] This section is intended to provide background or context for the embodiments of the invention set forth in the claims. The description herein is not an admission that it is prior art simply because it is included in this section.

[0003] Transmit antenna switching, or intelligent antenna switching, is a function known as TAS (Transmit Antenna Selection) or ASDiV (Antenna Switch to Diversity). It refers to the automatic switching of the transmit antenna between the main antenna and the diversity antenna. During use, the antenna performance of smartphones is easily affected by how they are held and placed. When the performance of one antenna degrades due to being held or obstructed, the phone signal can automatically switch to another antenna for transmission. This function effectively solves the signal congestion problems caused by holding or obstructing the antenna, enabling faster and more stable data connections and transmission speeds, thus providing users with a more reliable mobile connection experience. With the rapid development of wireless communication technology and the rapid improvement of communication capabilities, transmit antenna switching technology has become an essential technology for wireless communication terminals such as smartphones and laptops.

[0004] To ensure the reliability and availability of transmit antenna switching performance in wireless communication terminals, a rigorous testing procedure is essential. Currently, industry testing of the transmit performance of multi-antenna wireless communication terminals primarily involves separate testing of the main antenna and diversity antenna transmit performance: with transmit antenna switching disabled, both the main antenna and diversity antenna are locked as the sole transmit antenna, and the TRP (Transmit Relay Performance) is tested for each locked transmit antenna. In other words, there is currently no effective solution in the industry to accurately evaluate the transmit antenna switching performance of wireless communication terminals. The main reason is:

[0005] 1. Transmit antenna switching algorithms are proprietary algorithms of each terminal equipment manufacturer. The conditions and mechanisms for triggering transmit antenna switching vary among manufacturers, including specific input triggers from external control sources such as base station control, user control, and received signal levels, as well as internal triggers from their own sensors (based on proximity to the human body and other objects). In current OTA testing systems, it is difficult to simulate different transmit antenna switching trigger conditions.

[0006] 2. Enable the transmit antenna switching function and test according to the existing wireless terminal transmission performance test method. If the transmit antenna switching is triggered at a certain spatial test point, it may cause the two polarization components measured at that point to come from different transmit antennas, thus leading to incorrect measurement results.

[0007] 3. The test results of the transmitting antenna switching performance are closely related to the anechoic chamber layout, including the turntable and fixtures, as well as the relative position of the communication antenna and the terminal under test. Therefore, the same device under test may produce drastically different transmitting antenna switching performance test results when tested in different anechoic chambers.

[0008] 4. The triggering of the transmitting antenna switching condition has a certain degree of randomness. Therefore, even if the same terminal under test is repeatedly tested in the same test system, the test results will differ due to this randomness.

[0009] In summary, there is an urgent need for a technical solution that can overcome the above-mentioned shortcomings and achieve accurate and efficient testing of the switching performance of wireless terminal transmitting antennas. Summary of the Invention
