1. A mobile station device comprising:
- reception circuitry configured to and/or programmed to receive first system information indicating a carrier type; and
decoding circuitry configured to and/or programmed to monitor a common search space for a control channel, whereinOFDM symbols for the control channel are given by the first system information indicating the carrier type,in a case that the first system information indicating the carrier type is set to a first value, positions of the OFDM symbols for the control channel are predefined positions in a subframe, andin a case that the first system information indicating the carrier type is set to a second value, the positions of the OFDM symbols for the control channel are given by received second information.

5. A communication method used for a mobile station device comprising:
-
receiving a first system information indicating a carrier type; determining OFDM symbols for a control channel based on the first system information indicating the carrier type; and monitoring a common search space for a control channel, wherein in a case that the first system information indicating the carrier type is set to a first value, positions of the OFDM symbols for the control channel are predefined positions in a subframe, in a case that the first system information indicating the carrier type is set to a second value, the positions of the OFDM symbols for the control channel are given by received second information, the receiving step uses reception circuitry configured to and/or programmed to receive the first system information indicating the carrier type, and the determining step uses decoding circuitry configured to and/or programmed to monitor the common search space for the control channel.

6. A communication method used for a base station device comprising:
-
transmitting a first system information indicating a carrier type, determining OFDM symbols for a control channel based on the first system information indicating the carrier type, encoding the control channel, and transmitting the control channel on a common search space, wherein in a case that the first system information indicating the carrier type is set to a first value, positions of the OFDM symbols for the control channel are predefined positions in a subframe, in a case that the first system information indicating the carrier type is set to a second value, the positions of the OFDM symbols for the control channel are given by received second information, the transmitting the first system information indicating the carrier type step uses transmission circuitry, and the determining step uses decoding circuitry configured to and/or programmed to monitor the common search space for the control channel.
