Abstract

A method of mapping transport sequences to component carriers in a wireless communication system is disclosed. A method of mapping transport sequences to a plurality of component carriers in a transmitter of a wireless communication system that supports carrier aggregation comprises changing the order of the transport sequences in accordance with mapping information; and transmitting the transport sequences of which order has been changed, to a receiver through the plurality of component carriers.

Claims

1. A method of mapping transport sequences to a plurality of component carriers in a transmitter of a wireless communication system that supports carrier aggregation, the method comprising:

changing order of the transport sequences in accordance with mapping information; and

transmitting the transport sequences of which order has been changed, to a receiver through the plurality of component carriers.

2. The method of claim 1, wherein the mapping information is for cyclic-shifting the transport sequences.

3. The method of claim 1, wherein the mapping information is varied depending on a transmission time interval (TTI).

4. The method of claim 1, wherein the transport sequences are transport blocks transferred from a medium access control (MAC) layer.

5. The method of claim 1, wherein the transport sequences are a series of sequences generated by channel coding the transport blocks transferred from a medium access control (MAC) layer.

6. A transmitter of mapping transport sequences to a plurality of component carriers in a wireless communication system that supports carrier aggregation, the transmitter comprising:

a first means of changing order of the transport sequences in accordance with mapping information; and

a second means of carrying the transport sequences of which order has been changed in the plurality of component carriers and transmitting the transport sequences to a receiver.

7. The transmitter of claim 6, wherein the mapping information cyclic-shifts the transport sequences.

8. The transmitter of claim 6, wherein the mapping information is varied depending on a transmission time interval (TTI).

9. The transmitter of claim 6, wherein the first means exists between a medium access control (MAC) layer and a physical layer.

10. The transmitter of claim 6, wherein the first means exists between a coding chain and a physical processing chain of a physical layer.
