Abstract  Abstract

A method and apparatus for transmitting and receiving a hybrid automatic repeat request (HARQ-ACK) signal in a communication system. The method comprising: identifying transmission modes of at least two cells; Receiving at least one transport block on a physical downlink shared channel (PDSCH) indicated by a corresponding physical downlink control channel (PDCCH) in one of the at least two cells; Identifying a plurality of physical uplink control channel (PUCCH) resources; And transmitting at least one HARQ-ACK signal for the at least one transport block based on the plurality of PUCCH resources, wherein the corresponding PDCCH includes at least one control channel element (CCE) Wherein a first PUCCH resource of the plurality of PUCCH resources is defined based on a transmission of the corresponding PDCCH and a first CCE used for a transmission mode supporting a maximum of two transport blocks, The second PUCCH resource is defined based on the second CCE following the first CCE.
