Abstract  Abstract

A method for operating a UE, user equipment, in an LTE network, Long Term Evolution, using TDD mode, time division duplex, the method comprising: receiving allocations of downlink resources transmitted from an eNB, evolved node B, in an enhanced physical downlink control channel, ePDCCH, consisting of one or more elements of enhanced control channel, eCCE, indexed within physical resource blocks, PRB, indexed; transmitting a hybrid ARQ acknowledgment corresponding to downlink data transmitted in physical downlink shared channel resources, PDSCH, through a physical uplink control channel resource, PUCCH, which is implicitly indicated by an ePDCCH detected that allocates said PDSCH resources; where the ePDCCH is detected in a downlink subframe belonging to a specified grouped window of M indexed downlink subframes and where the PUCCH resource is defined by a PUCCH resource index ** (See formula) ** representing a PUCCH Format 1 resource that is a subframe index function, lowest index of a PRB that contains at least one eCCE in the detected ePDCCH, and the lowest eCCE index; characterized in that the method further comprises: for each of the subframes i in the grouped window having an ePDCCH that allocates downlink resources, calculate the PUCCH resource index ** (See formula) ** in such a way that the Assignment of consecutive PUCCH resource indices is done by the ePDCCHs sorted according to an ordered list of the eCCEs that make up the ePDCCHs that depends on the PRB index, the subframe index and the eCCE index.
