METHOD FOR TRANSMITTING/RECEIVING SIGNAL AND DEVICE THEREFOR

摘要

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and a device for a terminal to transmit an uplink signal according to a normal HARQ operation in a wireless communication system supporting a carrier merge, the method comprising the steps of: forming a first cell set with a FDD and a second serving cell set with a TDD; receiving a PHICH signal from a subframe #(n−m−p) of the first serving cell, or receiving a PDCCH signal from a subframe #(n−m) of the first serving cell; and transmitting a PUSCH signal from a subframe #n of the second serving cell, in correspondence to the PHICH signal or the PDCCH signal, wherein n is an integer greater than or equal to 0, m is an integer greater than or equal to 1, and p is an integer greater than or equal to 1.

1. A method for transmitting an uplink signal by a User Equipment (UE) according to a HARQ (hybrid automatic repeat and request) operation in a wireless communication system supporting carrier aggregation, the method comprising:
configuring a first cell to FDD (frequency division duplex) and a second cell to TDD (time division duplex); transmitting an initial PUSCH (physical uplink shared channel) in a first subframe of the second cell; receiving a PHICH (physical HARQ indicator channel) for the initial PUSCH and a PDCCH (physical downlink control channel) for a retransmission of the initial PUSCH, in a second subframe of the first cell; and transmitting a HARQ retransmission of the initial PUSCH in a third subframe of the second cell, according to the PHICH and the PDCCH received on the first cell.
