Mobile terminal testing device and transmitting antenna testing method

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;

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; and

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.

2. The testing device according to claim 1 , 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.

3. The testing device according to claim 2 , wherein

the controller notifies the set parameter to the call processing module and establishes a communication conforming to the set parameter.

4. The testing device according to claim 2 , wherein

the controller transmits the set scenario to the call processing module to carry out an operation according to the set scenario.

5. The testing device according to claim 1 , 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.

6. The testing device according to claim 1 , 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.

7. The testing device according to claim 6 , 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”.

8. A transmitting antenna testing method for a mobile terminal testing device which tests a mobile terminal including a plurally 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,

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,

the predetermined PDCCH includes control information which designates the transmitting antenna of the mobile terminal,

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”.
