Abstract:
1. A method for operating a UE (user equipment) in an LTE (Long Term Evolution) network using TDD (time division duplex) mode, comprising: receiving transmitted downlink resource allocations from an eNB (evolved Node B) in an enhanced physical downlink control channel (ePDCCH) made up of one or more indexed enhanced control channel elements (eCCEs) contained within indexed physical resource blocks (PRBs); transmitting a hybrid-ARQ acknowledgement corresponding to a detected ePDCCH allocating physical downlink shared channel (PDSCH) resources via a physical uplink control channel (PUCCH) resource that is implicitly indicated by the detected ePDCCH; and, wherein the ePDCCH is detected in a downlink subframe belonging to a specified bundling window of M indexed downlink subframes and wherein the PUCCH resource is defined by a PUCCH resource index n
