Abstract

A method and device for testing the radio frequency performance of a TD-LTE terminal. The steps of the method are: the comprehensive tester sets the system parameters required for the terminal to access the network, and connects the terminal to the comprehensive tester for radio frequency; the terminal performs a booting process; In the signaling process of establishing a dedicated radio bearer, configure the terminal to perform uplink semi-persistent scheduling and specify the terminal to transmit the uplink PUSCH signal on a fixed uplink subframe; the comprehensive tester collects and analyzes the radio frequency performance of the PUSCH signal. The device includes a main control unit, a system simulator, a radio frequency processing unit and a power distribution unit, and the radio frequency processing unit has a radio frequency transmitting unit, a radio frequency receiving unit and a local oscillator unit. The invention enables the comprehensive tester to test the radio frequency performance of the terminal.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for testing the radio frequency performance of a TD-LTE terminal. Background technique [0002] With the development of the modern communication industry and the maturity of TD-SCDMA standard terminals, TD-LTE (TD-SCDMA Longtermevolution) technology is constantly improving, and the production of TD-LTE terminals will gradually increase. In order to check the production quality and performance indicators of TD-LTE terminals, it must be tested by a terminal comprehensive tester. At present, there is no mature TD-LTE terminal comprehensive tester, which severely limits the R&D and production efficiency of TD-LTE terminal manufacturers, and increases the R&D and production costs of TD-LTE terminals. Contents of the invention [0003] The purpose of the present invention is to address the above technical problems and provide a method and device capa...
