Abstract: Methods and apparatuses are provided in which information for a length of a short transmission time interval (STU) is transmitted to a terminal. A timing advance for the terminal is transmitted to the terminal. The timing advance is included in a timing advance range among different timing advance ranges, and the timing advance range is associated with the information for the length of the STTI. A signal is transmitted to the terminal based on the information for the length of the STTI.
