Method for communication in system in which 4G and 5G coexist, and device therefor

A communication method of a base station the method comprising:

• transmitting, to a terminal, master system information, the master system information including first transmission information on additional system information;
• transmitting, to the terminal, the additional system information based on the first transmission information, the additional system information including second transmission information of a paging signal;
• and
• transmitting, to the terminal, the paging signal based on the second transmission information.

A terminal, comprising:

• a transceiver;
• and
• a controller configured to:
• receive, from a base station via the transceiver, master system information, the master system information including first transmission information on additional system information,
• receive, from the base station via the transceiver, the additional system information based on the first transmission information, the additional system information including second transmission information of a paging signal, and
• receive, from the base station via the transceiver, the paging signal based on the second transmission information.
