Title:
ロングタームエボリューションシステムにおける時分割複信のためのカバレッジ拡張および拡張型干渉軽減およびトラフィック適応
Document Type and Number:
Japanese Patent JP6500088
Kind Code:
B2
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)/down.link (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 sub- frames 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 repetitious, and may transmit UL repetiotions 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.
