Abstract
A wireless transmit/receive unit (WTRU) (152) in a wireless communications system includes a transceiver (153) for transmitting and receiving data from a plurality of base stations (154, 156, 357) and a controller (151) communicatively coupled to the transceiver (153) and configured to adjust an operation mode of the transceiver (153). In the WTRU (152), adjusting comprises configuring the transceiver (153) to begin a radio link handover procedure responsive to receiving a handover (HO) command from a first of the plurality of base stations (154, 156, 357) over a first communications link, specifying a first time, and reconfiguring the transceiver (153) to begin a radio link interruption procedure responsive to an expiry of the first time prior to completion of the radio link handover procedure. In the WTRU (152), the radio link interruption procedure first attempts to re-establish the first communications link.
