Abstract

A method, terminal, and base station for transmitting or receiving hybrid automatic repeat request acknowledgment (HARQ-ACK) information in a wireless communication system. The method includes receiving, from a base station (BS), first data on a first component carrier (CC) configured with frequency division duplex (FDD) and second data on a second CC configured with time division duplex (TDD), wherein one of the first and second CC is a primary CC (PCC) and another of the first and second CC is a secondary CC (SCC); determining HARQ-ACK timing for the first data based on a configuration of the PCC; determining HARQ-ACK timing for the second data based on the configuration of the PCC; transmitting, to the BS on the PCC, HARQ-ACK information for the first data using the determined HARQ-ACK timing for the first data and HARQ-ACK information for the second data using the determined HARQ-ACK timing for the second data.
