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

  • receiving, at the terminal, system information including information associated with a sub-frame configuration of a multimedia broadcast multicast service single frequency network (MBSFN) sub-frame;

    receiving, at the terminal, a dedicated message including information to be used for identifying whether to detect a physical downlink control channel (PDCCH) in a sub-frame of an MBSFN sub-frame for decoding a physical downlink shared channel (PDSCH) in the sub-frame of the MBSFN sub-frame;

    determining whether to detect the PDCCH in the sub-frame of the MBSFN sub-frame for decoding the PDSCH in the sub-frame of the MBSFN sub-frame based on the information;

    identifying whether the sub-frame of the MBSFN sub-frame is used for an MBSFN transmission or a positioning reference signal transmission;

    in case that the terminal determines to detect the PDCCH in the sub-frame of the MBSFN sub-frame for decoding the PDSCH in the sub-frame of the MBSFN sub-frame, performing detection of the PDCCH in the sub-frame of the MBSFN sub-frame except that the sub-frame is used for the MBSFN transmission or the positioning reference signal transmission; and

    in case that the terminal determines not to detect the PDCCH in the sub-frame of the MBSFN sub-frame for decoding the PDSCH in the sub-frame of the MBSFN sub-frame, not performing detection of the PDCCH in the sub-frame of the MBSFN sub-frame for decoding the PDSCH.
