1. A user equipment (UE) for dynamically reconfiguring an uplink-downlink (UL-DL) time-division duplexing (TDD) configuration, having computer circuitry configured to:

  • receive a UL-DL reconfiguration indicator from a node to dynamically reconfigure a flexible subframe (FlexSF) to a different UL-DL transmission direction from a semi-static UL-DL configuration, wherein the FlexSF is capable of changing an UL-DL transmission direction;

    apply a DL channel timing based on a DL favored UL-DL configuration, wherein the DL favored UL-DL configuration includes more DL subframes than a semi-static UL-DL TDD configuration for the UE; and

    apply a UL channel timing based on a UL favored UL-DL configuration, wherein the UL favored UL-DL configuration includes more UL subframes than a semi-static UL-DL TDD configuration for the UE.
