Abstract

Apparatus for transceiving signals in accordance with a frame structure supportive of a plurality of carriers in a wireless communication system and method thereof are disclosed. The method includes transceiving the signal using at least one carrier in accordance with the frame structure supportive of the carriers. The frame structure includes the carriers. First carrier among the carriers includes a downlink static assignment region assigned statically for a user equipment to receive the signal from a base station, a downlink dynamic assigned region assigned in a manner of being flexibly changed and an uplink transmitting region for the user equipment to transmit an uplink signal. Second carrier among the carriers includes an uplink transmitting region for the user equipment to transmit the uplink signal. The first or second carrier includes an uplink static assignment region assigned statically for an uplink transmission of the user equipment.

Claims

1. A method of transceiving signals by a user equipment in accordance with a frame structure of a cell in a wireless communication system, the method comprising:

transceiving the signals using a first carrier and a second carrier in accordance with the frame structure of the cell,

wherein the first carrier comprises a fixed downlink assignment region, an uplink assignment region, and a dynamic downlink assignment region,

wherein a resource index of the dynamic downlink assignment region is indicated by the fixed downlink assignment region,

wherein the resource index of the dynamic downlink assignment region is changeable, and

wherein the second carrier comprises only the uplink assignment region;

receiving, from a base station, information including each maximum transmission power value corresponding to each resource block (RB) of a subframe of the uplink assignment region, each RB of the subframe having a different maximum transmission power value; and

transmitting a signal through the corresponding RB of the subframe of the uplink assignment region based on a transmission power value, the transmission power value being equal to or smaller than the maximum transmission power value of the corresponding RB.

2. The method of claim 1, wherein the frame structure of the cell is different from a frame structure of a neighboring cell.

3. The method of claim 1, wherein the uplink assignment region of the second carrier comprises a static assignment region.

4. The method of claim 1, wherein the uplink assignment region of the second carrier comprises a device-to-device (D2D) communication region.

5. The method of claim 1, wherein the first carrier corresponds to a primary carrier and the second carrier corresponds to a secondary carrier.

11. The method of claim 1, wherein the transceiving further comprises transceiving the signals through the dynamic downlink assignment region based on the resource index.

6. A user equipment for transceiving signals in accordance with a frame structure of a cell in a wireless communication system, the user equipment comprising;

a transceiver; and

a processor,

wherein the processor is configured to control that the transceiver to transceive the signals using carrier first carrier and a second carrier in accordance with the frame structure of the cell,

wherein the first carrier comprises a fixed downlink assignment region, an uplink assignment region, and a dynamic downlink assignment region,

wherein a resource index of the dynamic downlink assignment region is indicated by the fixed downlink assignment region,

wherein the resource index of the dynamic downlink assignment region is changeable,

wherein the second carrier comprises only the uplink assignment region,

wherein the processor is configured to control the transceiver to receive, from a base station, information including each maximum transmission power value corresponding to each resource block (RB) of a subframe of the uplink assignment region, each RB of the subframe having a different maximum transmission power value, and

wherein the processor is configured to control the transceiver to transmit a signal through the corresponding RB of the subframe of the uplink assignment region based on a transmission power value, the transmission power value being equal to or smaller than the maximum transmission power value of the corresponding RB.

7. The apparatus of claim 6, wherein the frame structure of the cell is different from a frame structure of a neighboring cell.

8. The apparatus of claim 6, wherein the uplink assignment region of the second carrier comprises an uplink static assignment region.

9. The apparatus of claim 6, wherein the uplink assignment region of the second carrier comprises a device-to-device (D2D) communication region.

10. The apparatus of claim 6, wherein the first carrier corresponds to a primary carrier and the second carrier corresponds to a secondary carrier.

12. The apparatus of claim 6, wherein the processor is configured to control the transceiver to transceive the signals through the dynamic downlink assignment region based on the resource index.
