Abstract: A method and apparatus for half-duplex (HD) frequency division duplex (FDD) (HD-FDD) operation are disclosed. The method in a wireless transmit/receive unit (WTRU) includes monitoring a first frequency for all downlink sub-frames for downlink communication except during a cell specific uplink frame, retuning to a second frequency and transmitting a scheduling request (SR) during a WTRU specific period of the cell specific uplink frame, wherein the WTRU specific period is based on a duty cycle, and retuning to the first frequency and receiving an uplink grant in a subsequent sub-frame.
