Problems solved by technology

Therefore, in the traditional TRP test method based on TDD (Time Division Duplex, Time Division Duplex) mode, in order to measure the transmit power of the terminal to be tested, it is necessary to set the spectrum analyzer to the average mode to obtain the transmit power of the terminal to be tested (that is, the average power), but this method must allow the spectrum analyzer and the base station emulator to perform time slot synchronization
However, in order to meet the conditions of time slot synchronization between the spectrum analyzer and the base station emulator, there are higher requirements for each device in the OTA test system, and at the same time, complex settings are required, and high manpower and material costs are required for comprehensive testing. higher complexity
[0004] For the above-mentioned problems that the traditional TRP test based on the TDD mode requires high cost or high complexity of test implementation, no effective solution has been proposed so far.

Abstract

The present invention provides a TRP test method and a device based on the TDD mode and relates to the technical field of communications. The method is applied to an OTA test system in the TDD mode. The method comprises the steps of when the test mode of a frequency spectrum analyzer is in a maximum power capturing mode, acquiring the maximum transmitting power of a to-be-measured terminal within a preset period of time by the frequency spectrum analyzer; according to the maximum power, acquiring the average power of the to-be-measured terminal; adopting the average power as the transmitting power of the to-be-measured terminal in the TDD mode. According to the technical scheme of the invention, the TRP test cost and the test complexity, based on the TDD mode, can be comprehensively reduced.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a TRP test method and device based on a TDD mode. Background technique [0002] TRP (total radiated power, total radiated power) test is a routine test in OTA (Over-The-Air, air) test system, by measuring the transmission power of DUT (Device Under Test, the terminal under test) to investigate the performance of DUT radiation performance. [0003] In the traditional TRP test, the DUT needs to maintain a signaling connection with the base station emulator in the OTA test system, and the spectrum analyzer will measure the transmit power of the DUT at various test angles. In the communication system in TDD mode, the DUT does not continuously transmit signals, that is, there may be different states in each time slot, such as transmitting time slots (with transmission), receiving time slots (without transmission) and switching time slots (possibly launch), etc. Therefore, in...
