1. A method for transmitting information in a mobile communication system providing a low latency service, the method comprising:
- obtaining, by a base station, delay time requirements of terminals, wherein the delay time requirements represent required delay times of data packets according to characteristics of services provided to each of the terminals;
determining, by the base station, time intervals for transmitting control information for respective terminals based on the obtained delay time requirements for the respective terminals;
determining, by the base station, offsets of the respective terminals;
transmitting, by the base station, control information to the respective terminals through control regions, wherein the control information includes the time intervals and the offsets,wherein the control regions for transmitting control information for the respective terminals are configured based on the time intervals and the offsets for the respective terminals;
before the transmitting of control information, obtaining frame numbers based on the time intervals and the offsets; and
configuring the control regions by shortframes respectively corresponding to the obtained frame numbers;
wherein in the obtaining of the frame numbers, frame numbers satisfying a condition of (SN % interval)==offset are obtained, wherein SN denotes a shortframe number.
