Method for transmitting signal for improving coverage and apparatus for same

A user equipment (UE) for use in a wireless communication system, the UE comprising:

• a transmitter and receiver;
• and
• a processor, wherein the processor is configured to control the receiver to:
• receive channel state information reference signal (CSI-RS) configuration information, wherein the CSI-RS configuration information informs the UE on a position of resource elements (REs) for CSI-RS in a configured time interval;
• receive a set of repeated physical downlink control channels (PDCCHs), on REs in the set of time intervals, wherein the set of repeated PDCCHs have the same control information, and the set of time intervals includes the configured time interval, and
• receive a physical downlink shared channel (PDSCH) corresponding to the set of repeated PDCCHs,
• wherein, as for a repeated PDCCH in the configured time interval, the same control information is punctured on the REs for CSI-RS.

A method for transmitting data by a base station (BS) in a wireless communication system, comprising:

• transmitting channel state information reference signal (CSI-RS) configuration information, wherein the CSI-RS configuration information informs a UE on a position of resource elements (REs) for CSI-RS in a configured time interval;
• transmitting a set of repeated physical downlink control channels (PDCCHs) on REs in a set of time intervals, wherein the set of repeated PDCCHs have the same control information, and the set of time intervals includes the configured time interval;
• and
• transmitting a physical downlink shared channel (PDSCH) corresponding to the set of repeated PDCCHs,
• wherein, as for a repeated PDCCH in the configured time interval, the same control information is punctured on the REs for CSI-RS.
