Method and device for transmitting response information, and resource allocation for response information transmission according to transmission conditions in a wireless communication system

Abstract

A method for allocating a resource for response information transmission and transmitting according to transmission conditions in a wireless communication system according to the present invention comprises the steps of: setting a specific field value of a control channel depending on the allocation method by determining a transmission method or transmission quantity of data to be transmitted to a user's terminal from a data channel, a method of generating response information of the data according to the transmission quantity or transmission method, and an allocation method for indicating the response information resource; transmitting the data channel including the transmitting data and the control channel to the user's terminal; confirming the response information, which is transmitted from a resource allocated by the allocation method, for the data transmitted from the user's terminal; and determining whether the transmitted data area retransmitted according to the confirmed response information.

1 . A method of receiving response information in a wireless communication system, the method comprising: configuring a carrier aggregation for a user equipment, the carrier aggregation comprising an aggregation of a primary component carrier and a secondary component carrier; transmitting, to the user equipment, first control information through a first Physical Downlink Control Channel (PDCCH) of the primary component carrier, and transmitting, to the user equipment, data through a first Physical Downlink Shared Channel (PDSCH) of the secondary component carrier, the first PDSCH being configured to be identified based on the first PDCCH; receiving, from the user equipment, first response information with respect to the data of the first PDSCH, the first response information being allocated on a resource having a first resource index; and determining whether to retransmit at least part of the data of the first PDSCH based on the first response information, wherein the first resource index of the first response information is determined based on an n.sub.CCE value, which is an index of a Control Channel Element (CCE) of the first PDCCH.
