System access method and apparatus of a narrowband terminal in a wireless communication system supporting wideband and narrowband terminals

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

• a transceiver;
• and
• a controller configured to:
• receive, from a base station via the transceiver, a first master information block (MIB) including information associated with a resource for a first physical downlink control channel (PDCCH), through a physical broadcast channel, the information indicating a frequency resource of the resource for the first PDCCH,
• identify the frequency resource of the resource for the first PDCCH based on the information associated with the resource for the first PDCCH,
• detect downlink control information including scheduling information based on the frequency resource of the resource for the first PDCCH, and
• receive, from the base station via the transceiver, system information through a first physical downlink shared channel (PDSCH) based on the scheduling information,
• wherein the system information includes information associated with a bandwidth of a downlink sub-band and a location of the downlink sub-band,
• wherein the system information further includes information associated with a bandwidth of an uplink sub-band and a location of the uplink sub-band, and
• wherein the system information is scheduled within a frequency range of the resource for the first PDCCH.

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

• transmitting a first master information block (MIB) including information associated with a resource for a first physical downlink control channel (PDCCH) through a physical broadcast channel, the information indicating a frequency resource of the resource for the first PDCCH;
• transmitting downlink control information including scheduling information through the first PDCCH based on the frequency resource of the resource for the first PDCCH;
• and
• transmitting, system information through a first physical downlink shared channel (PDSCH) based on the scheduling information,
• wherein the system information includes information associated with a bandwidth of a downlink sub-band and a location of the downlink sub-band,
• wherein the system information further includes information associated with a bandwidth of an uplink sub-band and a location of the uplink sub-band, and
• wherein the system information is scheduled within a frequency range of the resource for the first PDCCH.

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

• transmit downlink control information including scheduling information through the first PDCCH based on the frequency resource of the resource for the first PDCCH, and
• transmit system information through a first physical downlink shared channel (PDSCH) based on the scheduling information,
• wherein the system information includes information associated with a bandwidth of a downlink sub-band and a location of the downlink sub-band,
• wherein the system information further includes information associated with a bandwidth of an uplink sub-band and a location of the uplink sub-band, and
• wherein the system information is scheduled within a frequency range of the resource for the first PDCCH.
