Abstract: A method and apparatus for Time Division Duplex (TDD) operation in a wireless transmit/receive unit (WTRU) are disclosed. The method includes receiving a first TDD uplink (UL)/downlink (DL) configuration for a serving cell, receiving a second TDD UL/DL configuration for the serving cell, receiving an indication of directions to use for subframes with conflicting directions between the first TDD UL/DL configuration and the second TDD UL/DL configuration, using the first TDD UL/DL configuration for timing of UL scheduling and UL Hybrid Automatic Repeat Request (HARQ), using the second TDD UL/DL configuration for timing of DL scheduling and DL HARQ, and determining a direction for each subframe with conflicting directions based on the received indication, wherein on a condition that the determined direction for a subframe with conflicting directions is DL, receiving in the subframe in the DL.

Abstract: Systems and/or methods for supporting communications at a reduced bandwidth with a full bandwidth network such as a long-term evolution (LTE) network may be disclosed. For example, inband assignments such as downlink assignments and/or uplink grants may be provided and/or received and transmissions may be monitored and/or decoded based on the inband assignment. Additionally, information (e.g. a definition or configuration) associated with an ePDCCH may be provided and/or received and ePDCCH resources may be monitored and/or decoded based on such information. An indication for support of a reduced bandwidth by the full bandwidth network may also be provided and/or received and control channels in the reduced or narrow bandwidth may be monitored and/or decoded based on the indication. A PRACH preamble and/or a multi-type subframe definition may also be provided and/or used for support of such a reduced bandwidth.
