Abstract

Disclosed are a data transmission and reception method and a machine type communication (MTC) device using the same. The data transmission and reception method according to the present invention may include: extracting MTC bandwidth information through a downlink channel or signaling; receiving the downlink channel or signaling including MTC downlink control format information; detecting resource region information occupied by the MTC downlink control channel; and receiving the MTC downlink control channel using the resource region information occupied by the MTC downlink control channel.

Claims

1. A method of transmitting and receiving data in a machine type communication (MTC) device, the method comprising:

extracting MTC bandwidth information through a downlink channel or signaling;

receiving the downlink channel or signaling including MTC downlink control format information;

detecting resource region information occupied by an MTC downlink control channel; and

receiving the MTC downlink control channel using the resource region information occupied by the MTC downlink control channel,

wherein the resource region occupied by the MTC downlink control channel is positioned in the center of an entire system band on a frequency axis.

2. The method of claim 1, further comprising demodulating an MTC downlink data channel using the MTC downlink control channel.

3. The method of claim 1, wherein the downlink channel including the MTC downlink control format information further comprises downlink control format information for a user terminal.

4. The method of claim 2, wherein the MTC downlink control channel and the MTC downlink data channel are divided by frequency division multiplexing or time division multiplexing.

5. The method of claim 2, wherein the MTC downlink control channel and the MTC downlink data channel are included in a downlink data region for a user terminal.

6. The method of claim 1, wherein the downlink channel including the MTC downlink control format information is positioned in a first time region or a last time region of a downlink resource region for the MTC device, or in a top frequency region of the downlink resource region of the MTC device.

7. The method of claim 1, wherein the signaling including the MTC downlink control format information is radio resource control (RRC) signaling or layer 1 (L1) signaling.

8. The method of claim 1, further comprising:

when the MTC downlink control channel includes the control information for MTC uplink data transmission,

extracting control information for MTC uplink data transmission; and

transmitting MTC uplink data using an MTC uplink data channel and optionally an MTC uplink control channel.

9. The method of claim 8, wherein the MTC uplink data channel or the MTC uplink control channel is positioned within a downlink data region for a user terminal.

10. The method of claim 8, wherein the MTC uplink data channel and the MTC uplink control channel are divided by frequency division multiplexing.

11. The method of claim 8, wherein the MTC uplink data channel and the MTC uplink control channel occupy a top frequency region and a bottom frequency region of a bandwidth for the MTC device.

12. A machine type communication (MTC) device comprising:

a reception unit receiving at least one downlink channel or signaling;

a control unit detecting MTC bandwidth information and an MTC downlink control channel through the received downlink channel or signaling, demodulating an MTC downlink data channel using the MTC downlink control channel, and extracting control information for MTC uplink data transmission; and

a transmission unit transmitting uplink data on the basis of the control information for the MTC uplink data transmission, wherein the resource region occupied by the MTC downlink control channel is positioned in the center of an entire system band on a frequency axis.

13. The MTC device of claim 12, wherein the MTC downlink control channel and the MTC downlink data channel are divided by frequency division multiplexing or time division multiplexing.

14. A method of transmitting downlink data, the method comprising:

determining whether resource allocated for a machine type communication (MTC) device is included in a given resource period;

configuring a downlink frame according to information about a resource region for the MTC device and a bandwidth for the MTC device; and

transmitting the configured downlink frame to at least one MTC device, wherein the resource for the MTC device comprises a control channel and data channel for the MTC device and optionally an indicator for the control channel, and

wherein a resource region occupied by an MTC downlink control channel is positioned in the center of an entire system band on a frequency axis.
