A signal transmission method and apparatus are provided. A signal transmission apparatus may include a time hopping apparatus configured to calculate a difference between values of time hopping patterns corresponding to adjacent symbol transmission periods, and to determine, based on the calculated difference, whether a position of a time hopping pattern corresponding to one of the adjacent symbol transmission periods is to be adjusted, and a transmitter configured to transmit a signal in the adjacent symbol transmission periods based on a determination result obtained by the time hopping apparatus. Additionally, a related signal reception apparatus is provided.
