Specifically, the method comprises the steps of: receiving, from a base station, a downlink control signal including resource allocation information for resource blocks continuously allocated for the uplink data signal within allocable resource blocks; and transmitting the uplink data signal to the base station using the downlink control signal, wherein the continuously allocated resource blocks are updated to include a center resource block, when the allocable resource blocks include the center resource block of a system bandwidth. ## Claims ### Claim 1 A method of transmitting an uplink data signal by a user equipment (UE) in a narrowband wireless communication system, the method comprising: receiving, from a base station, a downlink control signal including resource allocation information about resource blocks contiguously allocated for the uplink data signal among allocable resource blocks; and transmitting the uplink data signal to the base station using the downlink control signal, wherein when the allocable resource blocks include a center resource block of a system bandwidth, the contiguously allocated resource blocks are updated to include the center resource block. ### Claim 2 (depends on 1) The method of claim 1, wherein a size of the resource allocation information has a fixed value irrespective of whether or not the allocable resource blocks include the center resource block. ### Claim 3 (depends on 1) The method of claim 1, wherein the resource allocation information indicates the contiguously allocated resource blocks except the center resource block and wherein when the allocable resource blocks include the center resource block, the contiguously allocated resource blocks indicated by the resource allocation information are updated to include the center resource block. ### Claim 4 (depends on 3) The method of claim 3, wherein when the allocable resource blocks include the center resource block of the system bandwidth, the contiguously allocated resource blocks indicated by the resource allocation information are updated to exclude a resource block of the last index. ### Claim 5 (depends on 1) The method of claim 1, wherein the resource allocation information includes a starting index of the contiguously allocated resource blocks and information on the number of the contiguously allocated resource blocks. ### Claim 6 A user equipment in a narrowband wireless communication system, comprising: a wireless communication module; and a processor configured to receive, from a base station, a downlink control signal including resource allocation information about resource blocks contiguously allocated for an uplink data signal among allocable resource blocks in a manner of being connected with the wireless communication module, the processor configured to transmit the uplink data signal to the base station using the downlink control signal, wherein when the allocable resource blocks include a center resource block of a system bandwidth, the contiguously allocated resource blocks are updated to include the center resource block. ### Claim 7 (depends on 6) The user equipment of claim 6, wherein a size of the resource allocation information has a fixed value irrespective of whether or not the allocable resource blocks include the center resource block. ### Claim 8 (depends on 6) The user equipment of claim 6, wherein the resource allocation information indicates the contiguously allocated resource blocks except the center resource block and wherein when the allocable resource blocks include the center resource block, the processor is configured to update the contiguously allocated resource blocks indicated by the resource allocation information to include the center resource block. ### Claim 9 (depends on 8) The user equipment of claim 8, wherein when the allocable resource blocks include the center resource block of the system bandwidth, the processor is configured to update the contiguously allocated resource blocks indicated by the resource allocation information to exclude a resource block of the last index. ### Claim 10 (depends on 6) The user equipment of claim 6, wherein the resource allocation information includes a starting index of the contiguously allocated resource blocks and information on the number of the contiguously allocated resource blocks.
