1. A method by a terminal in a wireless communication system, the method comprising:receiving control information including a measurement comparison threshold value and pattern information;
determining whether a channel measurement value is less than the threshold value;
decoding a downlink control channel including scheduling information for unicast data of the terminal in an almost blank subframe (ABS) indicated by the pattern information if the channel measurement value is equal to or greater than the threshold value; and
skipping the decoding of the downlink control channel in the ABS if the channel measurement value is less than the threshold value,
wherein respective pattern information corresponds to respective measurement comparison threshold value.
