Title:

METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING WIRELESS SIGNAL IN WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2016/036100

Kind Code:

A1

Abstract:

The present invention relates to a wireless communication system and, more particularly, to a method and a device therefor, the method comprising the steps of: configuring an FDD PCell and a TDD SCell; configuring a first UL-DL SF pattern to the TDD SCell according to pattern indication information received through an L1 signal; and transmitting, through an SR PUCCH, HARQ-ACK information related to an SF in which the transmission direction of the TDD SCell is UL on the basis of the first UL-DL SF pattern, wherein the HARQ-ACK information includes HARQ-ACK responses for both the PCell and the SCell when the transmission direction of the TDD SCell is DL in the SF on the basis of a reference UL-DL SF pattern configured to the TDD SCell in relation to a HARQ-ACK feedback, and the HARQ-ACK information includes an HARQ-ACK response for only the PCell when the transmission direction of the TDD SCell is UL in the SF on the basis of the reference UL-DL SF pattern.
