Method and apparatus for monitoring control information in wireless communication system

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting, to a terminal, at least one parameter for a search space to monitor downlink control information (DCI) related with power saving;
• and
• transmitting the DCI related with the power saving, on a common search space identified based on the at least one parameter, by a radio network temporary identifier (RNTI) for the power saving,
• wherein a wake up indicator included in the DCI related with the power saving is identified at the terminal, and
• wherein a physical downlink control channel (PDCCH) monitoring is performed at the terminal based on a value of the wake up indicator.

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

• a transceiver;
• and
• a processor coupled with the transceiver and configured to:
• receive, from a base station, at least one parameter for a search space to monitor downlink control information (DCI) related with power saving,
• receive the DCI related with the power saving, on a common search space identified based on the at least one parameter, by a radio network temporary identifier (RNTI) for the power saving,
• identify a wake up indicator included in the received DCI related with the power saving, and
• perform a physical downlink control channel (PDCCH) monitoring based on a value of the wake up indicator.
