Abstract

Disclosed herein relates to a resource allocation method for a machine type communication (MTC) device. The resource allocation method for the MTC device includes allocating a control channel with respect to a user terminal to a first time domain of a sub frame, and mixing at least one of a control channel with respect to the at least one MTC device, a data channel with respect to the user terminal, and a data channel with respect to the MTC device in a second time domain of the sub frame, and allocating the mixed channel to the second time domain of the sub frame. Accordingly, in a wireless communication system, control information and data may be transmitted and received to and from the MTC device while maintaining compatibility with the user terminal.

Claims

1. A method for allocating resources to at least one machine type communication (MTC) device, the method comprising:

allocating a control channel with respect to a user terminal to a first time domain of a sub frame;

mixing at least one of a control channel with respect to the at least one MTC device, a data channel with respect to the user terminal, and a data channel with respect to the MTC device in a second time domain of the sub frame, and allocating the mixed channel to the second time domain of the sub frame; and

transmitting, to the MTC device, information about a region occupied by the control channel with respect to the MTC device,

wherein the information about the region occupied by the control channel with respect to the MTC device includes at least one of a start symbol number and an end symbol number of the control channel with respect to the MTC device, a start symbol number of the data channel with respect to the MTC device, the number of symbols occupied by the control channel with respect to the MTC device, the number of resource blocks (RB), the number of subcarriers, the number of subcarrier groups, the number of resource block groups, and a configuration index.

2. The method of claim 1, wherein the control channel for the MTC device and the data channel with respect to the MTC device are divided by the data channel with respect to the user terminal in a frequency division multiplexing (FDM) manner.

3. The method of claim 2, wherein the control channel with respect to the MTC device is divided by the data channel with respect to the MTC device in any one of a time division multiplexing (TDM) manner, an FDM manner, and combination of TDM and FDM.

4. The method of claim 1, wherein the transmitting transmits the information about the region occupied by the control channel with respect to the MTC device to the at least one MTC device through any one of upper layer signaling higher than a physical layer, a broadcast channel with respect to the user terminal for transmitting system information to the user terminal, and a separate physical control channel for the MTC device.

5. An apparatus for allocating resources to at least one machine type communication (MTC) device, the apparatus comprising:

a resource allocation unit that allocates a control channel with respect to a user terminal to a first time domain of a sub frame, mixes at least one of a control channel with respect to the at least one MTC device, a data channel with respect to the user terminal, and a data channel with respect to the MTC device in a second time domain of the sub frame, and allocates the mixed channel to the second time domain of the sub frame; and

a transmission unit that transmits, to the MTC device, information about a region occupied by the control channel with respect to the MTC device,

wherein the information about the region occupied by the control channel with respect to the MTC device includes at least one of a start symbol number and an end symbol number of the control channel with respect to the MTC device, a start symbol number of the data channel with respect to the MTC device, the number of symbols occupied by the control channel with respect to the MTC device, the number of resource blocks (RB), the number of subcarriers, the number of subcarrier groups, the number of resource block groups, and a configuration index,

wherein the apparatus for allocating resources to at least one MTC device comprises one or more processors configured to embody a plurality of functional units of the apparatus including a resource allocation unit.

6. The apparatus of claim 5, wherein the control channel with respect to the MTC device and the data channel with respect to the MTC device are divided by the data channel with respect to the user terminal in a frequency division multiplexing (FDM) manner.

7. The apparatus of claim 6, wherein the control channel with respect to the MTC device is divided by the data channel with respect to the MTC device in any one of a time division multiplexing (TDM) manner, an FDM manner, and combination of TDM and FDM.

8. The apparatus of claim 5, wherein the transmission unit transmits the information about the region occupied by the control channel with respect to the MTC device to the at least one MTC device through any one of upper layer signaling higher than a physical layer, a broadcast channel with respect to the user terminal for transmitting system information to the user terminal, and a separate physical control channel for the MTC device.

9. A method for receiving machine type communication (MTC) data from a base station, the method comprising:
