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

摘要

The present invention relates to a method for transmitting and receiving an uplink signal for low-cost machine-type communication (MTC) used in a wireless communication system, and the apparatuses for supporting same. The base station of the present invention sets a maximum number of RBs capable of being allocated to the MTC device to be smaller than the total number of RBs in a system band supported by the base station. The MTC device of the present invention transmits an uplink signal through a physical uplink shared channel (PUSCH) on the basis of the maximum number of RBs capable of being allocated to the MTC device.

1. A method of transmitting an uplink signal, which is transmitted by a low-cost machine-type communication (MTC) device, the method comprising:
receiving a grant signal containing resource allocation information; and transmitting the uplink signal via a physical uplink shared channel (PUSCH) using at least one resource block (RB) determined based on a maximum number of RBs 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, wherein the maximum number of RBs capable of being allocated to the MTC device is smaller than a total number of RBs in a system band supported by an eNode B (eNB), and wherein the maximum number of RBs capable of being allocated to the MTC device has a value identical to one selected from a group consisting of:
a number of RBs contained in a downlink bandwidth assigned to the MTC device,a number resulting from multiplying the number of RBs contained in the downlink bandwidth assigned to the MTC device by a prescribed ratio,a number of RBs contained in an MTC cell-specific downlink bandwidth corresponding to a downlink bandwidth commonly assigned to at least one MTC device belonging to one cell, anda number resulting from multiplying the number of RBs contained in the MTC cell-specific downlink bandwidth corresponding to the downlink bandwidth commonly assigned to at least one MTC device belonging to one cell by a prescribed ratio.
