Method and apparatus for transmitting and receiving system information

A communication apparatus for receiving remaining minimum system information (RMSI) in a wireless communication system, the communication apparatus comprising:

• a memory;
• and
• a processor connected to the memory,
• wherein the processor is configured to control to:
• receive an synchronization signal (SS)/physical broadcast channel (PBCH) block including an SS and a PBCH in a half-frame;
• obtain, via the PBCH, information related to a monitoring window for receiving a physical downlink control channel (PDCCH) for the RMSI;
• receive the PDCCH within the monitoring window;
• and
• receive the RMSI based on the PDCCH,
• wherein monitoring windows related to SS/PBCH blocks having consecutive indexes among SS/PBCH blocks receivable in the half-frame are at least partially overlapped each other.

A method for transmitting remaining minimum system information (RMSI) by a base station in a wireless communication system, the method comprising:

• receiving an synchronization signal (SS)/physical broadcast channel (PBCH) block including an SS and a PBCH in a half-frame;
• transmitting a physical downlink control channel (PDCCH) for the RMSI based on information related to a monitoring window delivered via the PBCH;
• and
• transmitting the RSMI based on the PDCCH,
• wherein monitoring windows related to SS/PBCH blocks having consecutive indexes among SS/PBCH blocks receivable in the half-frame are at least partially overlapped each other.
