1. A device comprising:

  • a transceiver to receive, from a base station, a physical downlink shared channel (PDSCH) transmission; and

    processing circuitry to;

    classify downlink (DL) subframe types for a set of DL subframes associated with a first uplink (UL) subframe for transmission of a hybrid automatic report request acknowledgment (HARQ-ACK), wherein the DL subframe types comprise at least Type 1 subframes that are constructed by DL subframes that are associated with the first uplink (UL) subframe for transmission of HARQ-ACK according to a time division duplex (TDD) UL/DL configuration indicated in a system information block Type 1(SIB1) message; and

    perform physical uplink control channel (PUCCH) resources mapping based on the classified DL subframe Types for an acknowledgement transmission associated with PDSCH transmission receptionwherein the DL subframe types further comprise;

    Type 2 DL subframes that are constructed by;

    firstly identifying DL subframes that are associated with the first UL subframe for transmission of HARQ-ACK according to a higher layer configured DL-reference UL/DL configuration; and

    when the Type 1 DL subframes are overlapped with the Type 2 DL subframes, the overlapping subframes between Type 1 and Type 2 DL subframes are further removed from the Type 2 DL subframes.
