METHOD FOR CONFIGURING A HARQ RTT TIMER IN A CARRIER AGGREGATION SYSTEM AND A DEVICE THEREFOR |
摘要 |
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for configuring a HARQ RTT timer in a carrier aggregation system, the method comprising: configuring a plurality of cells including at least one FDD (Frequency Division Duplex) serving cell and at least one TDD (Time Division Duplex) serving cell; transmitting data in a subframe n via a SCell (Secondary Cell) being a FDD serving cell of the plurality of cells; and re-transmitting the data in a subframe m via the SCell, if a PCell (Primary Cell) is a TDD serving cell of the plurality of cells, wherein m is equal to or greater than n+k+4, wherein k is an interval between downlink transmission and transmission of associated HARQ (Hybrid-ARQ) feedback. |

1. A method for a base station operating in a wireless communication system, the method comprising:
configuring a plurality of cells including at least one FDD (Frequency Division Duplex) serving cell and at least one TDD (Time Division Duplex) serving cell; transmitting data in a subframe n via a SCell (Secondary Cell) being a FDD serving cell of the plurality of cells; and re-transmitting the data in a subframe m via the SCell, if a PCell (Primary Cell) is a TDD serving cell of the plurality of cells, wherein m is equal to or greater than n+k+4, wherein k is an interval between downlink transmission and transmission of associated HARQ (Hybrid-ARQ) feedback. |
