A method of a base station in a mobile communication system, the method comprising:

• transmitting, to a terminal, first control information on first type data;
• transmitting, to the terminal, second control information on second type data;
• and
• determining whether to terminate a transmission of the first type data that corresponds to the first control information based on at least one of the first control information or the second control information.

A terminal in a mobile communication system, the terminal comprising:

• a transceiver;
• and
• a controller configured to:
• receive, from a base station, first control information on first type data;
• identify whether second control information on second type data is received from the base station;
• and
• terminate decoding of the first type data if the second control information is received.
