METHODS AND SYSTEM FOR PERFORMING HANDOVER IN A WIRELESS COMMUNICATION SYSTEM |
摘要 |
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. |

1. A wireless transmit receive unit (WTRU) comprising a processor configured to:
determine that a radio link failure has occurred; and transmit a message to an evolved Node-B (eNode-B) in response to determining that the radio link failure has occurred, wherein the message comprises a radio network temporary identifier (RNTI) of the WTRU and a cell identity of a cell previously utilized by the WTRU. |
