Abstract
Technology for physical uplink control channel (PUCCH) resource mapping corresponding to an enhanced physical downlink control channel (ePDCCH) is disclosed. One method can include a node mapping a PUCCH resource nPUCCH(1) corresponding to an ePDCCH for PUCCH resource hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback. The PUCCH resource nPUCCH(1) can be determined using a lowest PRB index including at least one enhanced control channel element (eCCE) of ePDCCH resources and a total number of eCCE in one physical resource block (PRB).
