Abstract

According to one embodiment, a mobile terminal testing device which tests a mobile terminal including a plurality of transmitting antennas by transmitting/receiving radio signals between the mobile terminal testing device and the mobile terminal, includes a radio signal processing module configured to transmit and receive radio signals to and from the mobile terminal and a controller configured to cause the mobile terminal to switch one from another among the plurality of transmitting antennas by a predetermined radio signal transmitted to the mobile terminal via the radio signal processing module.

First claim

What is claimed is:

1 . A mobile terminal testing device which tests a mobile terminal including a plurality of transmitting antennas by transmitting/receiving radio signals between the mobile terminal testing device and the mobile terminal, the mobile terminal testing device comprising:
a radio signal processing module configured to transmit and receive radio signals to and from the mobile terminal; and a controller configured to cause the mobile terminal to switch one from another among the plurality of transmitting antennas by a predetermined radio signal transmitted to the mobile terminal via the radio signal processing module.

2 . The testing device according to claim 1 , wherein
the controller sends an RRC message to the mobile terminal to select a transmitting antenna according to an instruction from the testing device, and causes the mobile terminal to switch to a transmitting antenna designated by PDCCH.

3 . The testing device according to claim 2 , wherein
the controller measures a signal received from the mobile terminal in coincidence with a timing of causing the mobile terminal to switch to the transmitting antenna by the PDCCH.

4 . The testing device according to claim 1 , further comprising:
a call processing module, wherein the controller outputs to the call processing module, a first signal which enables the mobile terminal testing device to designate selection of a transmitting antenna, and a second signal which designates the transmitting antenna, and the call processing module transmits a predetermined RRC message to the mobile terminal based on the first signal and thereafter transmits a predetermined PDCCH to the mobile terminal based on the second signal.

5 . The testing device according to claim 4 , further comprising:
a user interface configured to set a parameter and a scenario for operating the mobile terminal testing device, wherein the controller controls operation of the mobile terminal testing device based on the parameter and the scenario thus set.

6 . The testing device according to claim 5 , wherein
the controller notifies the set parameter to the call processing module and establishes a communication conforming to the set parameter.

7 . The testing device according to claim 5 , wherein
the controller transmits the set scenario to the call processing module to carry out an operation according to the set scenario.

8 . The testing device according to claim 4 , further comprising:
a radio signal measurement module configured to measure the signal received from the mobile terminal, wherein the controller transmits an instruction signal which sets a timing of switching one from another among the transmitting antennas to the radio signal measurement module via the call processing module, and the radio signal measurement module starts measurement of the received signal at the timing.

9 . The testing device according to claim 4 , wherein
the predetermined RRC message includes a field for designating the selection of a transmitting antenna of the mobile terminal by the mobile terminal testing device, and the predetermined PDCCH includes control information which designates the transmitting antenna of the mobile terminal.

10 . The testing device according to claim 9 , wherein
the predetermined RRC message is “RRC Connection Reconfiguration” including a field “ue-TransmitAntennaSelection”, and the control information of the predetermined PDCCH is a DCI format 0 including a field “Antenna Selection mask”.

11 . A transmitting antenna testing method for a mobile terminal testing device which tests a mobile terminal including a plurality of transmitting antennas by transmitting/receiving radio signals between the mobile terminal testing device and the mobile terminal, the method comprising:
a step of enabling by an RRC message the mobile terminal testing device to designate selection of the plurality of transmitting antennas of the mobile terminal; and a step of designating a transmitting antenna of the mobile terminal by PDCCH.

12 . The testing method according to claim 11 , further comprising:
a step of measuring a signal received from the mobile terminal in coincidence with a timing of causing the mobile terminal to switch from an transmitting antenna to another by the PDCCH.

13 . The testing method according to claim 11 , wherein
the predetermined RRC message includes a field for designating the selection of the transmitting antenna of the mobile terminal by the mobile terminal testing device, and the predetermined PDCCH includes control information which designates the transmitting antenna of the mobile terminal.

14 . The testing method according to claim 13 , wherein
the predetermined RRC message is “RRC Connection Reconfiguration” including a field “ue-TransmitAntennaSelection”, and control information of the predetermined PDCCH is a DCI format 0 including a field “Antenna Selection mask”.
