Abstract:
Technology to provide conditional physical uplink control channel (PUCCH) resource allocation in time division duplex (TDD) for a hybrid automatic retransmission request-acknowledge (HARQ-ACK) transmission in a subframe n is disclosed. In an example, a user equipment (UE) can include computer circuitry configured to: Receive a downlink control channel within a prior specified subframe, wherein the prior specified subframe occurs in time before the subframe n; recognize a downlink control channel type received within the prior specified subframe is a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (EPDCCH); determine a PUCCH resource for the HARQ-ACK transmission using a lowest control channel element (CCE) index of the PDCCH when the received downlink control channel type is the PDCCH; and determine the PUCCH resource for the HARQ-ACK transmission using a lowest enhanced CCE (ECCE) index of the EPDCCH when the received downlink control channel type is the EPDCCH.
