Abstract

A mobile communication terminal test device includes: test signal transmitting means (40) for transmitting, to a mobile communication terminal (50), a test signal including a plurality of radio resource regions (1 to 8) each of which is surrounded by one or more sub-frames and one or more resource blocks; and response signal receiving means (14) for receiving a response signal to the test signal from the mobile communication terminal. The test signal transmitting means transmits, to the mobile communication terminal, the test signal which includes one radio resource region for each predetermined time interval (T) and in which the position of the radio resource region in the frequency axis direction varies for each predetermined time interval.

Description

technical field [0001] The invention relates to a mobile communication terminal testing device and a mobile communication terminal testing method for testing mobile communication terminals such as mobile phones or mobile terminals. Background technique [0002] In recent years, in mobile communication services, transmission speeds have been increased and multimedia services such as music and video have been realized. Along with this, the bandwidth of the communication frequency is also widened. For example, in the 3rd generation mobile communication system represented by W-CDMA (Wideband-Code Division Multiple Access), the maximum bandwidth is 5MHz, and in LTE (Long Term Evolution), the maximum bandwidth is 20MHz. In LTE-Advanced, which aims at high speed, the maximum bandwidth becomes 200MHz. [0003] In LTE or LTE-Advanced, the modulation and coding rate method and the number of resource blocks are specified according to the transmission channel conditions. Since the dat...
