Problems solved by technology

[0003] At present, MAT’s receiving terminal under test (Receiving Terminal Under Test, RTUT) transmission power measurement model does not consider the influence factors of the non-under-test radio (Radio Not Under Test, RNUT) on the RTUT in the actual application scenario. RTUT is an anisotropic colored interference
The objective existence of RNUT will actually cause the spatial transmission power of RTUT to be significantly different from that of RTUT alone, which will significantly reduce the accuracy of RTUT spatial transmission power measurement

Embodiment Construction

[0030] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention.

[0031] In order to describe the influence of RNUT on RTUT transmission power, RNUT can be equivalent to the colored noise source of RTUT, and the spatial transmission power measurement of RTUT is carried out under the environment of this colored noise source. At this time, the measurement of transmission power includes the existence of RUNT the influencing factors.

Abstract

The invention discloses a measuring method for the space transmission power of a receiving terminal under test in a multi-access terminal so as to improve the accuracy on measuring the space transmission power. The measuring method comprises the steps of: establishing a normal work environment for a wireless communication link and a wired communication link on the multi-access terminal; adjusting a relative power among the receiving terminal under test (RTUT), a radio not under test (RNUT) and a RTUT simulator; and measuring and obtaining the RTUT space transmission power of the multi-access terminal. Compared with prior art, the invention adopts an equivalent noise method to measure the transmission power of the receiving terminal under test, including an antenna, and has the advantages of low requirement on measurement environment and simple and easy test.

Description

technical field [0001] The present invention relates to a method for measuring the spatial transmission power of a receiving terminal under test (Receiving Terminal Under Test, RTUT), in particular to a method for measuring the spatial transmission power of an RTUT in a multi-access terminal (Multi-Access Terminal, MAT). Background technique [0002] The rapid development of cellular mobile network, wireless local area network, and radio and television network communication technologies has stimulated the public's demand to watch multi-service content on mobile terminals based on the above communication technologies, and Multi-Access Terminal (MAT) has emerged. [0003] At present, MAT’s receiving terminal under test (Receiving Terminal Under Test, RTUT) transmission power measurement model does not consider the influence factors of the non-under-test radio (Radio Not Under Test, RNUT) on the RTUT in the actual application scenario. For RTUT, it is an anisotropic colored int...
