METHOD FOR TRANSRECEIVING SIGNALS AND APPARATUS FOR SAME

摘要

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method for transmitting an uplink signal in the wireless communication system supporting carrier aggregation (CA), and to the apparatus for same, the method comprising the steps of: setting a scheduling cell, which has a first uplink-downlink (UL-DL) configuration, and setting a scheduled cell, which has a second TDD UL-DL configuration; and carrying out a HARQ process from the scheduled cell based on the number of HARQ processes for the scheduled cell.

主权项

1. A method for performing a hybrid automatic repeat request (HARQ) process in a wireless communication system supporting carrier aggregation, the method comprising:
setting a scheduling cell having a first uplink-downlink (UL-DL) configuration and a scheduled cell having a second TDD UL-DL configuration; and performing a HARQ process in the scheduled cell on the basis of the number of HARQ processes for the scheduled cell, wherein, when a combination of the first UL-DL configuration and the second UL-DL configuration corresponds to a UL-DL configuration combination of a first set, the number of HARQ processes for the scheduled cell is determined as the number of available uplink subframes*N (N≧2), wherein, when a combination of the first UL-DL configuration and the second UL-DL configuration corresponds to a UL-DL configuration combination of a second set, the number of HARQ processes for the scheduled cell is determined as the number of available uplink subframes+N (N≧1).
