Abstract
A method and apparatus are described for a hybrid automatic repeat request-acknowledgement, HARQ-ACK, signal in a communication system, the method comprising:identifying transmission modes of a first cell and a second cell in frequency division duplex, FDD;receiving one or more transport blocks by at least one of a physical downlink shared channel, PDSCH, transmission on the first cell or a PDSCH transmission on the second cell ;determining a physical uplink control channel, PUCCH, resource; andtransmitting the HARQ-ACK signal for the one or more transport blocks on the PUCCH resource,wherein the PUCCH resource is selected from a plurality of PUCCH resources, the plurality of PUCCH resources are associated with the transmission modes of the first cell and the second cell, andwherein at least one of the plurality of PUCCH resources for at least one of the PDSCH transmissions is determined based on at least one of physical downlink control channels, PDCCHs, corresponding to the at least one of the PDSCH transmissions respectively, andwherein the HARQ-ACK signal transmitted on the selected PUCCH resource denotes at least one of acknowledgement, ACK, negative acknowledgement, NACK, or discontinuous transmission, DTX, response for each of the one or more transport blocks.
