Patent ID: 8718003

Claim:
A user equipment capable of receiving communications from a cell comprising at least one base station, the user equipment (UE) comprising: a receiver configured to receive from the base station both a cell specific radio resource control (RRC) configuration comprising a cell specific resource offset parameter for a PUCCH carrying a HARQ-ACK, and a UE specific RRC configuration comprising a UE specific RS base sequence parameter and an UE specific resource offset parameter for the PUCCH carrying the HARQ-ACK; and a transmitter configured to transmit the PUCCH carrying the HARQ-ACK which is generated based on either the cell specific RRC configuration or the UE specific RRC configuration, wherein a resource index number for the PUCCH, n PUCCH (1) , is determined by the following equation: n PUCCH (1) =n CCE +N PUCCH (1) , where n CCE is a number of the smallest channel control element (CCE) used for transmission of a corresponding downlink control information scheduling a PDSCH for which the PUCCH carries the HARQ-ACK, and N PUCCH (1) is the UE specific resource offset parameter depending on the applicability in case the UE specific RRC configuration is applicable to the user equipment; otherwise N PUCCH (1) is the cell specific resource offset parameter.
