Method and Apparatus for Determining Uplink Control Channel Resources

User equipment (UE), comprising:

• a receiving unit 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;
• and
• a determining unit configured to determine uplink control channel (PUCCH) resources of the UE according to the specific parameter corresponding to the mapping manner of the E-PDCCH of the UE and a PUCCH calculation formula.

An eNB, comprising:

• a configuring unit configured to configure different specific parameters for different mapping manners of E-PDCCH of UE;
• and
• a transmitting unit configured to transmit the different specific parameters to the UE, or transmit a specific parameter corresponding to the mapping manner of the E-PDCCH of the UE to the UE, so that the UE determines its uplink control channel (PUCCH) resources according to the specific parameter corresponding to the mapping manner of its E-PDCCH and a PUCCH calculation formula.
