Embodiments of the present disclosure include methods, apparatuses, and instructions for receiving at a user equipment (UE) of a third generation partnership project (3GPP) network an offset value selected from a plurality of offset values in downlink control information. The UE also receives one or more enhanced control channel elements (eCCEs) of an enhanced physical downlink control channel (ePDCCH). The UE may then determine an allocation of an uplink resource for a transmission on a physical uplink control channel (PUCCH) based at least in part on the index of a first eCCE and the offset value.
