Enhanced self-contained time-division duplex subframe structure

A user equipment (UE) configured to communicate with a base station, the UE comprising one or more processors and memory configured to:

• process a downlink (DL) self-contained time division duplex (TDD) subframe, received from the base station, comprising a physical downlink shared channel (PDSCH), a physical downlink control channel (PDCCH), and a guard period, wherein the PDSCH, the PDCCH, and the guard period are located within the DL self-contained TDD subframe prior to a physical uplink control channel (PUCCH);
• and
• generate, for transmission to the base station, data to be sent in the PUCCH of the DL self-contained TDD subframe.

At least one non-transitory machine readable storage medium having instructions embodied thereon for a base station to communicate with a user equipment (UE), the instructions when executed cause the base station to:

• generate, for transmission to the UE, a downlink (DL) self-contained time division duplex (TDD) subframe comprising a physical downlink shared channel (PDSCH), a physical downlink control channel (PDCCH), and a guard period, wherein the PDSCH, the PDCCH, and the guard period are located within the DL self-contained TDD subframe prior to a physical uplink control channel (PUCCH);
• and
• process the PUCCH within the DL self-contained TDD subframe, received from the UE.
