Abstract
User equipment (UE), includes: a receiver configured to receive a specific parameter configured for a mapping manner of an enhanced physical downlink control channel (E-PDCCH) of the UE by an eNB, wherein the specific parameter configured for the mapping manner of the E-PDCCH corresponds to a localized mapping or a distributed mapping; and a processing circuit coupled to a memory configured to determine uplink control channel (PUCCH) resources of the UE according to the specific parameter corresponding to the localized or distributed mapping of the E-PDCCH of the UE and a PUCCH calculation formula.
