Abstract
Technology to provide 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 first circuitry configured to detect a downlink control channel within a prior specified subframe that is received in time before the subframe n. The UE can include second circuitry configured to: determine that the downlink control channel detected within the prior specified subframe is one of a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (EPDCCH); and determine one of a legacy PUCCH resource for the HARQ-ACK transmission when the downlink control channel detected within the prior specified subframe is the PDCCH or an enhanced PUCCH resource for the HARQ-ACK transmission when the downlink control channel detected within the prior specified subframe is the EPDCCH.
