Patent ID: 8902786

Claim:
A method for communication between a User Equipment (UE) and a Node B (NB) in a communication system, the method comprising: receiving, from the NB, a common radio resource control (RRC) configuration information comprising a common resource offset parameter for a physical uplink control channel (PUCCH) carrying a hybrid automatic repeat request acknowledge (HARQ-ACK) in response to a physical downlink share channel (PDSCH) transmission, and a UE specific RRC configuration information comprising a UE specific resource offset parameter for the PUCCH carrying the HARQ-ACK in response to the PDSCH transmission; receiving, from the NB, a downlink control information (DCI) through a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (ePDCCH) constructed by at least one channel control element (CCE) and data through a PDSCH associated with the PDCCH or the ePDCCH; identifying a PUCCH resource, n PUCCH (1) , based on n CCE and N (1) PUCCH , n CCE being an index of a first CCE used for transmission of the DCI, and N PUCCH (1) being defined based on either the UE specific resource offset parameter or the cell specific resource offset parameter; identifying at least one orthogonal cover and at least one cyclic shift based on the PUCCH resource, n PUCCH (1) ; and transmitting the HARQ-ACK on the PUCCH based on the PUCCH resource, n PUCCH (1) , at least one orthogonal cover, and at least one cyclic shift, wherein when the UE specific resource offset parameter is configured, N PUCCH (1) is defined based on the UE specific resource offset parameter.
