Method and device for testing throughput of multiple terminals

Abstract

The invention provides a testing method and apparatus for the throughput of multiple terminals, applied to architecture of a multi-probe darkroom. The throughput testing method comprises: obtaining the interfering intensity of a plurality of tested terminals arranged in the multi-probe darkroom; for the plurality of first tested terminals whose interfering intensity is smaller or equal to a preset intensity value, sending a plurality of test signals from a channel simulator in parallel wherein the channel simulator sends the plurality of test signals through the different probes in the multi-probe darkroom to the plurality of the first tested terminals in parallel; and respectively adjusting the emission power of the plurality of test signals, the wave coming direction of the plurality of test signals, and the placing postures of the plurality of first tested terminals to obtain the throughput change information of the first tested terminals. According to the embodiments of the invention, based on the interfering intensity among the tested terminals, the method is adopted using the parallel sending of test signals to test the throughput for the plurality of terminals producing no interference or weak interference. While ensuring the accuracy, the test efficiency can be raised.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a multi-terminal throughput testing method and device. Background technique [0002] The throughput performance of an LTE terminal directly affects the user experience of the terminal. MIMO technology (Multiple Input Multiple Output technology) is one of the core technologies for improving throughput in LTE. MIMO technology needs to be applicable in a wireless propagation environment with relatively low spatial correlation and rich multipath components. The multi-antenna performance of an LTE terminal directly affects the spatial channel conditions, thus affecting the applicability of MIMO technology and affecting the throughput performance of the terminal. The MIMO over-the-air technology is used to test the multi-antenna receiving performance of the terminal. [0003] The multi-probe anechoic chamber method is one of the existing MIMO OTA (multiple-input multi...
