PHYSICAL UPLINK CONTROL CHANNEL (PUCCH) RESOURCE MAPPING USING AN ENHANCED PHYSICAL DOWNLINK CONTROL CHANNEL (ePDCCH)
First Claim
1. A method for physical uplink control channel (PUCCH) resource mapping corresponding to an enhanced physical downlink control channel (ePDCCH) from a node, comprising:
- mapping a PUCCH resource nPUCCH(1) corresponding to an ePDCCH for PUCCH resource hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback, wherein the PUCCH resource nPUCCH(1) is 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).

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).
