Abstract
Provided are a method and apparatus of performing a HARQ in a multiple carrier system. A receiver determines the size of a soft buffer to be used in an effective HARQ process on the basis of the maximum number of effective HARQ processes over a plurality of component carriers and stores the received transport block in the soft buffer. The present invention enables the performance of a HARQ in an efficient manner by using multiple carriers in the event the size of the soft buffer is limited.
Claims13
A method of performing a hybrid automatic repeat request (HARQ) in a multiple carrier system, the method comprising:
- determining a size of a soft buffer used in an effective HARQ process based on a maximum number of effective HARQ processes over a plurality of component carriers;
- receiving a transport block;
- storing the transport block into the soft buffer;
- and
- transmitting a reception acknowledgement for the transport block.
A receiver for supporting multiple carriers, comprising:
- a reception unit configured to receive a transport block;
- a transmission unit configured to transmit a reception acknowledgement for the transport block;
- and
- a hybrid automatic repeat request (HARQ) entity configured to determine a size of a soft buffer used in an effective HARQ process based on a maximum number of effective HARQ processes over a plurality of component carriers and store the transport block into the soft buffer.
