Abstract  Abstract

A method and system for performing handover in a third generation (3G) long term evolution (LTE) system are disclosed. A source evolved Node-B (eNode-B) makes a handover decision based on measurements and sends a handover request to a target eNode-B. The target eNode-B sends a handover response to the source eNode-B indicating that a handover should commence. The source eNode-B then sends a handover command to a wireless transmit/receive unit (WTRU). The handover command includes at least one of reconfiguration information information regarding timing adjustment relative timing difference between the source eNode-B and the target eNode-B information regarding an initial scheduling procedure at the target eNode-B and measurement information for the target eNode-B. The WTRU then accesses the target eNode-B and exchanges layer 1/2 signaling to perform downlink synchronization timing adjustment and uplink and downlink resource assignment based on information included in the handover command.
