Method and apparatus for transmission and reception of multiple timing transmission schemes in wireless cellular communication system

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

• receiving, from a base station, a configuration message for setting a transmission type of the terminal to a first transmission type, wherein the transmission type includes the first transmission type and a second transmission type which are determined based on a transmission time interval;
• identifying whether a timing advance value of the terminal is smaller than a predetermined value;
• monitoring control information associated with the first transmission type in a first search space, based on the timing advance value of the terminal being smaller than the predetermined value;
• and
• monitoring control information associated with the second transmission type in a second search space, based on the timing advance value of the terminal being larger than the predetermined value.

A base station in a wireless communication system comprising:

• a transceiver configured to transmit and receive signals;
• and
• at least one processor configured to:
• transmit, via the transceiver to a terminal, a configuration message for setting a transmission type of the terminal to a first transmission type, wherein the transmission type includes the first transmission type and a second transmission type which are determined based on a transmission time interval;
• identify whether a timing advance value of the terminal is smaller than a predetermined value;
• transmit, via the transceiver to the terminal, control information associated with the first transmission type in a first search space, based on the timing advance value of the terminal being smaller than the predetermined value;
• and
• transmit, via the transceiver to the terminal, control information associated with the second transmission type in a second search space based on the timing advance value of the terminal being larger than the predetermined value.
