The invention provides a multi-terminal throughput test method and device, and is applied to the framework of a channel simulator and a reverberation chamber. The throughput test method comprises the steps that the interference intensity between multiple tested terminals arranged in the reverberation chamber is acquired; as for multiple first tested terminals of which the interference intensity is less than or equal to a preset intensity value, multiple test signals of different test bands are issued to the channel simulator in parallel, and multiple test signals are transmitted to the multiple first tested terminals by the channel simulator through the communication antenna of the reverberation chamber in parallel; and the transmitting power of multiple test signals is respectively adjusted, and throughput change information of multiple first tested terminals is respectively acquired. According to the multi-terminal throughput test method and device, the mode of performing throughput testing by issuing the test signals in parallel is adopted on multiple terminals having no or weak interference according to the interference intensity between all the tested terminals so that the test efficiency can be enhanced under the premise of ensuring the accuracy.
Description
technical field [0001] The invention relates to the field of communication technology, 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 channel emulator plus reverberation chamber method is one of the existing MIMO OTA (multiple-inpu...
