Apparatus and method of system information transmission and reception on a carrier supporting multiple bandwidth parts

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

• communicating, with a base station, on a serving cell;
• identifying whether an active downlink (DL) bandwidth part (BWP) of the serving cell is configured with a common search space (CSS) for monitoring system information for the serving cell, the active DL BWP being a subset of a total bandwidth of the serving cell;
• receiving, from a base station, a radio resource control (RRC) message including the system information for the serving cell, in case that the active DL BWP is not configured with the CSS;
• and
• receiving, in a paging occasion from the base station, system information change indication associated with the system information for the serving cell by monitoring the paging occasion, in case that the active DL BWP is configured with the CSS to monitor paging.

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

• a transceiver configured to transmit and receive a signal;
• and
• a controller coupled with the transceiver and configured to:
• communicate, with a terminal, on a serving cell,
• identify whether an active downlink (DL) bandwidth part (BWP) of the serving cell is configured with a common search space (CSS) for monitoring system information for the serving cell, the active DL BWP being a subset of a total bandwidth of the serving cell,
• transmit, to the terminal, a radio resource control (RRC) message including the system information for the serving cell, in case that the active DL BWP is not configured with the CSS, and
• transmit, in a paging occasion to the terminal, system information change indication associated with the system information for the serving cell, in case that the active DL BWP is configured with the CSS.
