Method and device for determining uplink data and control signal transmission timing in wireless communication system

A method performed by a terminal in a wireless communication system, the method comprising:

• receiving, from a base station, a radio resource control (RRC) message including a set of values for a transmission time interval (TTI) offset between a timing with a downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH) to a timing where the PUSCH is transmitted, wherein each value in the set of values corresponds to a number of TTIs between the timing with the DCI and the timing where the PUSCH is transmitted;
• receiving, from the base station, first DCI scheduling a first PUSCH, wherein the first DCI includes a number of bits associated with a single value in the set of values;
• and
• transmitting, to the base station, uplink data on the first PUSCH, in a TTI determined based on the timing with the first DCI and the single value associated with the number of bits in the first DCI.

A base station in a wireless communication system, the base station comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• transmit, to a terminal, a radio resource control (RRC) message including a set of values for a transmission time interval (TTI) offset between a timing with a downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH) to a timing where the PUSCH is received, wherein each value in the set of values corresponds to a number of TTIs between the timing with the DCI and the timing where the PUSCH is received,
• transmit, to the terminal, first DCI scheduling a first PUSCH, wherein the first DCI includes a number of bits associated with a single value in the set of values, and
• receive, from the terminal, uplink data on the first PUSCH, in a TTI according to the timing with the first DCI and the single value associated with the number of bits in the first DCI.
