24. The at least one non-transitory machine readable medium of claim 20, wherein the determining allocation of an uplink resource of the PUCCH for HARQ-ACK transmission comprises one selected from a group consist ing of:

determining a hybrid allocation of an uplink resource of a PUCCH for HARQ-ACK transmission using a backward compatible carrier (n⁽¹⁾_PUCCH) is given by f(n_eCCE,m)+ACK/NACK resource indicator (ARI)+AP+N⁽¹⁾_PUCCH,m,

determining an ARI-based allocation of an uplink resource of a PUCCH for HARQ-ACK transmission given by a value n_eCCE,s+ARI+N⁽¹⁾_PUCCH,s, wherein the value is associated with one or more of a specific subframe, a signaled value, a physical downlink shared channel, and a semi-persistent scheduling (SPS), and

determining allocation of an uplink resource of the PUCCH for HARQ-ACK bundling for resource allocation for subframe n for an ePDCCH transmission according to;

25. The at least one non-transitory machine readable medium of claim 20, wherein the determining allocation of an uplink resource of the PUCCH for HARQ-ACK transmission comprises one selected from:

determining, for an ePDCCH used in a subframe and configured for PUCCH format 3, an allocation of an uplink resource of a PUCCH for HARQ-ACK transmission based on an ACK/NACK resource indicator (ARI) offset value;

determining, for an ePDCCH used in a subframe and configured for PUCCH format 3, an allocation of an uplink resource of a PUCCH for HARQ-ACK transmission using transmit power controls (TPCs), other than in a subframe having downlink assignment index (DAI) equal to one on a primary cell, to indicate a used PUCCH format 3 resource among four configured resources;

determining, for an ePDCCH used in a subframe and configured for one of a PUCCH format 3 and PUCCH format 1b with channel selection for the user equipment configured for carrier aggregation, an allocation of an uplink resource of a PUCCH for HARQ-ACK transmission that includes the ARI offset value for an ePDCCH transmitted on a primary cell; and

determining the allocation of the uplink resource of the PUCCH for HARQ-ACK transmission using a user equipment specific starting offset for ePDCCH set s configured by RRC signaling for a downlink (DL) subframe for ePDCCH and using a cell specific starting offset for ePDCCH set s configured by RRC signaling for DL subframes associated with legacy PDCCH.
