Test signal generation apparatus and method based on LTE-advanced system

摘要

To provide a technique for simplifying a parameter setting process required to generate a test signal based on an LTE-Advanced system. Carrier arrangement designation means 25 displays a screen for selecting one of an intra-band type or an inter-band type as the arrangement of a plurality of component carriers used in an LTE-Advanced system such that one of the intra-band type or the inter-band type is designated. Parameter file designation means 26 designates a parameter file to be allocated to the component carrier among test signal generating parameter files stored in a parameter file storage means 24. Parameter and frequency band allocation means 27 designates the component carrier to which the designated parameter file can be allocated and the allocated frequency band for communication in which the component carriers are arranged.

1. A test signal generation apparatus based on an LTE-Advanced system comprising:
a display unit; an operation unit; parameter file storage means for storing in advance test signal generating parameter files which can be allocated to a plurality of component carriers used to test an operation of a device under test, which is a base station or a user equipment corresponding to the LTE-Advanced system, or an RF device used in the base station or the user equipment; carrier arrangement designation means for displaying, on the display unit, a screen for selecting one of an intra-band type in which the plurality of component carriers are contiguously or non-contiguously arranged in one allocated frequency band for communication and an inter-band type in which the plurality of component carriers are divided and arranged in different allocated frequency bands for communication such that the operation unit is operated to designate one of the intra-band type and the inter-band type; parameter file designation means for displaying a screen for selecting the parameter files stored in the parameter file storage means on the display unit such that the operation unit is operated to designate any one of the parameter files; parameter and frequency band allocation means for displaying, on the display unit, a screen of a list of the plurality of component carriers and for designating at least one component carrier in the list and a screen for selecting the type of the allocated frequency band for communication in which the component carrier in the list is arranged, when the parameter file designation means designates the parameter file, such that the operation unit is operated to designate the component carrier to which the designated parameter file is allocated and the allocated frequency band for communication in which the component carrier is arranged; and a test signal generation unit that generates test signals for each component carrier in the designated allocated frequency band for communication on the basis of information designated by the carrier arrangement designation means and the parameter and frequency band allocation means.
