Method for transmitting control information on low-cost machine-type communication, and apparatus for supporting same

A low-cost machine-type communication (MTC) device transmitting an uplink signal, comprising:

• a radio frequency (RF) unit configured to transmit/receive a signal;
• and
• a processor configured to control the RF unit,
• the processor configured to control the RF unit to receive a uplink grant signal containing resource allocation information, the processor configured to control the RF unit to transmit the uplink signal via PUSCH (physical uplink shared channel) using at least one or more RBs determined based on the maximum number of RBs (resource blocks) capable of being allocated to the MTC device and the resource allocation information,
• wherein the resource allocation information indicates one or more RBs for the PUSCH within the maximum number of RBs capable of being allocated to the MTC device and wherein the maximum number of RBs capable of being allocated to the MTC device is configured to be smaller than the total number of RBs in a system band supported by an eNode B (eNB).

A method of receiving an uplink signal, which is received by an eNode B (eNB) from a low-cost machine-type communication (MTC) device, comprising the steps of:

• transmitting an uplink grant signal based on the maximum number of RBs capable of being allocated to the MTC device;
• and
• receiving an uplink signal via PUSCH (physical uplink shared channel) corresponding to the uplink grant signal from the MTC device,
• wherein the uplink grant signal contains resource allocation information indicating one or more RBs for the PUSCH within the maximum number of RBs capable of being allocated to the MTC device, wherein the uplink signal is received via the PUSCH (physical uplink shared channel) using at least one or more RBs determined based on the maximum number of RBs capable of being allocated to the MTC device and the resource allocation information and wherein the maximum number of RBs capable of being allocated to the MTC device is configured to be smaller than the total number of RBs in a system band supported by an eNode B (eNB).

An eNode B (eNB) receiving an uplink signal from a low-cost machine-type communication (MTC) device in a wireless communication, comprising:

• a radio frequency (RF) unit configured to transmit/receive a signal;
• and
• a processor configured to control the RF unit,
• the processor configured to control the RF unit to transmit an uplink grant signal based on the maximum number of RBs capable of being allocated to the MTC device, the processor configured to control the RF unit to receive an uplink signal via PUSCH (physical uplink shared channel) corresponding to the uplink grant signal from the MTC device,
• wherein the uplink grant signal contains resource allocation information indicating one or more RBs for the PUSCH within the maximum number of RBs capable of being allocated to the MTC device, wherein the uplink signal is received via the PUSCH (physical uplink shared channel) using at least one or more RBs determined based on the maximum number of RBs capable of being allocated to the MTC device and the resource allocation information and wherein the maximum number of RBs capable of being allocated to the MTC device is configured to be smaller than the total number of RBs in a system band supported by an eNode B (eNB).
