A base station defines a short TTI (transmission time interval) equal to the length of one subslot as the minimum unit of a time resource for data transmission in a subframe including a plurality of subslots, determines the RS type the terminal will use for transmission, among a plurality of RS types, based on the positions of RSs (reference signals) within the short TTI, and sends information on the RS type the terminal will use for transmission to the terminal.
