Methods and apparatuses are provided in which a radio resource control (RRC) message is transmitted to a terminal. A set of values for an offset between a transmission time interval (TTI) with a downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH) to a TTI where the PUSCH is transmitted is included in the RRC message. First DCI scheduling a first PUSCH is transmitted to the terminal. A number of bits associated with one value in the set of values is included in the first DCI. Uplink data on the PUSCH is received from the terminal, in a TTI determined by using the RRC message and the number of bits in the DCI.
