Abstract

A base station device that communicates with a mobile station device is provided. The base station device uses a physical broadcast channel to transmit information instructing the mobile station device to monitor a common search space or an enhanced common search space for a physical downlink channel.

Claims

1. (canceled)

2. 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, wherein

OFDM symbols for the control channel are given by the first system information indicating the carrier type.

3. The mobile station device according to claim 2:

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 is predefined positions in a subframe, and

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 is given by received second information.

4. The mobile station device according to claim 2:

the first system information indicates either one of a first carrier type and a second carrier type, and

a set of first signals is transmitted in a first downlink carrier of the first carrier type and not transmitted in a second downlink carrier of the second carrier type.

5. A base station device comprising:

transmission circuitry configured to and/or programmed to transmit first system information indicating a carrier type, wherein

the transmission circuitry is configured to and/or programmed to transmit a control channel on a common search space, and

OFDM symbols for the control channel are given by the first system information indicating the carrier type.

6. The base station device according to claim 5:

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 is predefined positions in a subframe, and

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 is given by received second information.

7. The base station device according to claim 5:

the first system information indicates either one of a first carrier type and a second carrier type, and

a set of first signals is transmitted in a first downlink carrier of the first carrier type and not transmitted in a second downlink carrier of the second carrier type.

8. A communication method used for a mobile station device comprising:

receiving a first system information indicating a carrier type; and

monitoring a common search space for a control channel, wherein

OFDM symbols for the control channel are given by the first system information indicating the carrier type.

9. A communication method used for a base station device comprising:

transmitting a first system information indicating a carrier type, and

transmitting a control channel on a common search space, wherein

OFDM symbols for the control channel are given by the first system information indicating the carrier type.
