发明名称 A METHOD AND APPARATUS FOR EFFICIENT HANDOVER IN LTE
摘要 An efficient use of downlink (DL) air-interface bandwidth during handoff of user equipment from a source cell to a target is provided. In conjunction with a handoff message to ensure receipt, expedited status exchanges are provided so that initial communications do not require a subsequent retransmission of duplicate data. A method for transmitting a dedicated Random Access Channel (RACH) preamble and cell information, receiving a RACH from the user equipment to start communication, and transmitting a handover message and a radio link control (RLC) status message or an UL grant in response to receiving the RACH is provided. Also, a method for receiving a handover message and target cell information from a source cell to start handover negotiations, initiating communication with target cell using the target cell information, receiving a handover message and (RLC) status message, and using the received information to approximate status reporting is provided.
