Abstract  Abstract

A method (500) for mapping physical uplink control channel resources, PUCCH, corresponding to an enhanced physical downlink control channel, ePDCCH, from a node, comprising: receiving from the node on a wireless device a parameter for a map of a PUCCH resource corresponding to the ePDCCH for feedback acknowledgment of hybrid automatic repeat request, HARQ-ACK, of PUCCH resources; transmit from the wireless device to the HARQ-ACK feedback node of the ePDCCH through a PUCCH based on the map; and mapping (510) the PUCCH resource corresponding to the ePDCCH for HARQ-ACK feedback of PUCCH resources, in which the PUCCH resource is determined using a minimum PRB index that includes at least one improved control channel element , eCCE, of ePDCCH resources and a total number of eCCE in a physical resource block, PRB; characterized in that the PUCCH resource is represented by for frequency division duplexing, FDD, where E is the total number of eCCE in a PRB, is the minimum PRB index that includes at least one eCCE of ePDCCH resources, is an index Starting PRB for an ePDCCH region, neCCE is a first eCCE index number in a minimum PRB used for the transmission of the corresponding ePDCCH in a downlink subframe where 0 <= neCCE <E, and is a PUCCH channel index starting for an ePUCCH region in an uplink subframe and is configured by upper layers for each user equipment, UE; or the PUCCH resource is represented by for time division duplexing, TDD, where E is the total number of eCCE in a PRB, is a starting PRB index for an ePDCCH region, is a starting PUCCH channel index for an ePUCCH region in an uplink subframe and is configured by upper layers for each user equipment, UE, is the minimum PRB index that includes at least one eCCE of ePDCCH resources in a n-km downlink subframe, neCCE is a first eCCE index number used for the transmission of the corresponding ePDCCH in the downlink subframe n-km, where n is an uplink subframe associated with the downlink subframe n-km, km is the highest value small in an associated downlink set K> = {k0, k1, ··· kM-1} with an ePDCCH in the downlink subframe n - km, where M is the number of elements in the set K and 0 < = m <= M-1, and is a PRB number of ePDCCH used for the transmission of ePDCCH in the downlink subframe n-ki.
