Abstract

There are provided a data transmission and reception method of a machine type communication (MTC) device, and an MTC device using the same. The data transmission and reception method of the MTC device includes: extracting information related to an MTC band from a downlink frame received from a base station, searching for an MTC downlink resource region in the downlink frame based on the information related to the MTC band, and extracting MTC data for the corresponding MTC device from the MTC downlink resource region. The MTC band includes a band through which at least a physical broadcast channel and a synchronization channel are transmitted.

Claims

5. The data transmission and reception method of claim 1, wherein the MTC downlink band includes at least one resource block located at a central part of a downlink system bandwidth.

6. A data transmission and reception method of a machine type communication (MTC) device, comprising:

extracting information related to an MTC uplink band from a downlink frame received from a base station;

configuring an uplink frame including an MTC uplink resource region based on the information related to the MTC uplink band; and

transmitting the uplink frame to the base station,

wherein the MTC uplink band includes at least one resource block on which physical random access channel (PRACH) is transmitted.

7. The data transmission and reception method of claim 6, wherein the information related to the MTC uplink band includes at least one piece of information among information about an MTC uplink bandwidth, information about the location of an MTC uplink band, information about an MTC uplink control channel, and information about an MTC uplink data channel.

8. The data transmission and reception method of claim 6, wherein the MTC uplink bandwidth is the same as or narrower than an uplink system bandwidth.

9. A downlink data transmission method comprising:

configuring a downlink frame including information related to a machine type communication (MTC) downlink band and information related to an MTC uplink band; and
