Patent ID: 10588125

Abstract:
Methods and systems are disclosed for use by a wireless transmit/receive unit (WTRU) operating in a coverage enhanced (CE) or coverage enhancement mode. The WTRU may receive a first Time Division Duplex (TDD) uplink (UL)/downlink (DL) subframe configuration and may receive a second TDD UL/DL subframe configuration. The WTRU may determine one or more subframes to use for receiving DL repetitions based on the first TDD UL/DL subframe configuration, and one or more subframes to use for transmitting UL repetitions based on the second TDD UL/DL subframe configuration. The WTRU may receive DL repetitions of a DL signal only in the determined one or more subframes for receiving DL repetitions, and may transmit UL repetitions of a UL signal only in the determined one or more subframes for transmitting UL repetitions. The WTRU may receive a TDD transmission using enhanced Interference Mitigation and Traffic Adaptation (eIMTA) capability.
