Problems solved by technology

[0004] However, this test method has the following problems: Massive MIMO base station equipment has a large number of channels. Taking a 64-channel base station equipment as an example, if it is necessary to test the transmission performance of 8-channel data, the channel simulator needs to have a bidirectional radio frequency with 64 receivers and 8 transmitters. function, with 1024 logical channels
This means that the Massive MIMO base station equipment is tested according to the traditional cable cascading method, which has the problems of complicated connection and low test efficiency

Abstract

The invention discloses a base station performance test method, device and system. The performance test system comprises a spherical probe wall, a channel simulator and test equipment; according to the channel model of the tested equipment, probes distributed in a spherical probe wall can be selected, the selected probes are used for collecting test signals emitted by the tested equipment, and then the channel simulator is used for simulating an actual propagation channel and processing the test signals, so that the performance of the tested equipment can be evaluated through a processing result received by the test equipment. Thus, for different tested devices with different antenna numbers, the test can be completed through the test system, and the accuracy of the channel simulation testis effectively ensured.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method, device and system for testing the performance of a base station. Background technique [0002] With the development of communication technology, the service content of the communication industry has shifted from voice services to data services, such as: live video services, online game services, etc. The rapid development of these data services requires mobile communication networks to have high capacity, wide coverage, low time Delay and other features. In order to improve the peak rate and spectrum efficiency, Massive (large-scale) MIMO (Multiple-Input Multiple-Output; Multiple-Input Multiple-Output) technology is introduced in the field of communication technology. Using this technology, the base station equipment is configured with 64 arrays and 128 antennas, and can transmit up to 16 channels of independent data in parallel. Compared w...
