Claim:
1. A method for Time Division Duplex (TDD) operation in a wireless transmit/receive unit (WTRU), the method comprising: receiving, by the WTRU via a system information block (SIB), a first TDD uplink (UL)/downlink (DL) reference configuration for a serving cell, wherein the first TDD UL/DL reference configuration is cell-specific; receiving, by the WTRU, a second TDD UL/DL reference configuration for the serving cell; receiving, by the WTRU via physical layer signaling, a third TDD UL/DL reference configuration for the serving cell; using, by the WTRU, the received first TDD UL/DL reference configuration for timing of UL scheduling and UL Hybrid Automatic Repeat Request (HARQ); using, by the WTRU, the received second TDD UL/DL reference configuration for timing of DL HARQ; and determining, by the WTRU, a UL or DL direction for a subframe based on the received third TDD UL/DL reference configuration; wherein on a condition that the determined direction for the subframe is DL, receiving DL transmissions in the subframe.
