Method for establishing extended narrowband in narrowband wireless communication system, and apparatus therefor

A user equipment in a narrowband wireless communication system, comprising:

• a transceiver;
• and
• a processor configured to receive, from a base station, a downlink control signal including resource allocation information about virtual physical resource blocks (PRBs) contiguously allocated for an uplink data signal among allocable virtual PRBs in a manner of being connected with the transceiver, the processor configured to transmit the uplink data signal to the base station based on the contiguously allocated PRBs indicated by the resource allocation information,
• wherein the allocable virtual PRBs are virtually contiguous PRBs excluding a center PRB from a system bandwidth,
• wherein based on the allocated virtual PRBs including PRBs on both sides of the center PRB, the uplink data signal is transmitted using the contiguously allocated PRBs including the center PRB, and
• wherein a number of the contiguously allocated PRBs is a fixed value regardless of whether or not the center resource block is included in the allocable PRBs.
