Abstract:
A user terminal is disclosed, where a band to use is limited to a partial narrow band in a system band. The user terminal includes a transmitter that transmits and/or a receiver that receives a signal, and a controller that controls repetitious reception and/or repetitious transmission of a control channel in a random access procedure based on a coverage enhancement level for a random access channel. A radio base station that communicates with a user terminal is also disclosed, where a band to use is limited to a partial narrow band in a system band. The radio base station includes a transmitter that transmits and/or a receiver that receives a signal, and a controller that controls to transmit information to make the user terminal control repetitious reception and/or repetitious transmission of a control channel in a random access procedure based on a coverage enhancement level for a random access channel.
