Abstract
A disclosed base station transmits a broadcast channel to a user device a predefined number of times in a predetermined cycle for communication with the user device. The base station includes a repetition unit configured to repeat the broadcast channel, after the broadcast channel is channel-coded, for the predefined number of times to generate multiple broadcast channels; and a signal waveform changing unit configured to process the generated broadcast channels such that the processed broadcast channels have different signal waveforms. Positions of the broadcast channels in the order of transmission in the predetermined cycle are associated with the signal waveforms of the broadcast channels.
