User terminal, radio base station and radio communication method

A radio base station comprising:

• a processor that generates a random access response including configuration information of a Machine-Type Communication (MTC) physical downlink control channel (MPDCCH), which is different from and has reduced bandwidth than a physical downlink control channel (PDCCH), the configuration information including information to indicate a frequency per narrowband;
• and
• a transmitter that transmits the random access response,
• wherein the transmitter transmits downlink control information in a terminal-specific search space (UE-specific Search Space) of the MPDCCH to be monitored based on the configuration information acquired from the random access response in order to transmit signals which cannot be transmitted using the PDCCH, and
• wherein the transmitter transmits downlink control information with Cyclic Redundancy Code (CRC) scrambled by Cell-Radio Network Temporary Identifier (C-RNTI) in a common search space of the MPDCCH.

A radio communication method for a terminal, comprising:

• acquiring, from a random access response, configuration information of a Machine-Type Communication (MTC) physical downlink control channel (MPDCCH), which is different from and has reduced bandwidth than a physical downlink control channel (PDCCH), the configuration information including information to indicate a frequency per narrowband;
• and
• monitoring a terminal-specific search space (UE-specific Search Space) of the MPDCCH based on the configuration information acquired from the random access response in order to receive signals which cannot be received using the PDCCH,
• wherein the terminal decodes downlink control information with Cyclic Redundancy Code (CRC) scrambled by Cell-Radio Network Temporary Identifier (C-RNTI) in a common search space of the MPDCCH downlink control channel.
