Abstract

Provided are a method whereby a terminal transmits an acknowledgement/not-acknowledgement (ACK/NACK) with a primary cell and a secondary cell aggregated, and a device for supporting the method. The method comprises: receiving data by a downlink subframe of a secondary cell; and transmitting an ACK/NACK for the data by an uplink subframe of a primary cell, wherein: the time interval between the downlink subframe and the uplink subframe is determined by a first hybrid automatic repeat request (HARQ) timing or a second HARQ timing; the first HARQ timing is an HARQ timing which is applied when the primary cell is used alone; and the second HARQ timing is an HARQ timing which is additional to the first HARQ timing.

Claims8

Dependent claims

A method for transmitting acknowledgement/negative acknowledgement (ACK/NACK) information, the method performed by a user equipment (UE) configured with a primary cell and a secondary cell and comprising:

receiving data in a plurality of downlink subframes of the cell;
generating ACK/NACK bits for the data;
and
transmitting ACK/NACK information informing the ACK/NACK bits in an uplink subframe of the primary cell,
wherein the primary cell is a cell using a time division duplex (TDD) frame and the secondary cell is a cell using a frequency division duplex (FDD) frame,
wherein the primary cell is configured with one of uplink-downlink configurations in a following table 1,

wherein, in the table 1, D denotes a downlink subframe, S denotes a special subframe, and U denotes an uplink subframe, and
wherein, when physical uplink control channel (PUCCH) format 3 is configured for transmission of the ACK/NACK information, the ACK/NACK bits are arranged as a time order of the plurality of downlink subframes and a most significant bit (MSB) of the ACK/NACK bits informs ACK/NACK for data received in a first downlink subframe among the plurality of downlink subframes and the ACK/NACK information informing the ACK/NACK bits are transmitted through the PUCCH format 3.
