Abstract:
Uplink control channel resource allocation for an enhanced downlink control channel is disclosed. A first example method disclosed herein includes receiving, at a user equipment (UE), a downlink control channel carrying a physical uplink control channel (PUCCH) resource indicator, mapping the PUCCH resource indicator to a first offset, mapping a position of the downlink control channel to a second offset, and mapping a linear combination of the first and second offsets to an index identifying a first PUCCH resource. A second example method disclosed herein includes, in response to receiving, at a UE, an indication of a dynamic resource offset in an enhanced physical downlink control channel (ePDCCH) transmitted in a first ePDCCH set, determining a position of the ePDCCH and a subframe offset, and processing the indication of the dynamic resource offset, the position and the subframe offset to determine an allocated uplink control channel resource for the UE.
