Abstract

The embodiment of the invention provides an antenna spatial correlation measuring method and device and a terminal device. The method comprises the following steps: in a measurement mode, measuring and acquiring a measurement quantity related to antenna spatial correlation measurement, and sending the measurement quantity related to antenna spatial correlation measurement to a testing instrument. After entering into the measurement mode, the terminal device measures and calculates the measurement quantity required by antenna spatial correlation measurement and sends the measurement results to the testing instrument; and through antenna spatial correlation parameters displayed by the testing instrument, the result of terminal device antenna spatial correlation can be calculated, thereby providing a basis for optimizing the antenna design by an antenna engineer and a hardware design engineer.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for measuring antenna spatial correlation, and terminal equipment. Background technique [0002] In the third-generation mobile communication system and the fourth-generation mobile communication system, in order to improve channel capacity, transmission rate and communication quality, multiple input multiple output (Multiple Input Multiple Output, hereinafter referred to as: MIMO) multi-antenna array wireless transmission is often used. Technology, while the air interface (Over the Air, hereinafter referred to as: OTA) is the main means of measuring the hardware implementation of multi-antenna arrays, which can verify the terminal's ability to support multi-antenna communication in a wireless environment. At present, the OTA measurement indicators mainly include throughput, total radiated power (Total Radiated Power, hereinafter referre...
