METHOD AND APPARATUS FOR CONTROLLING HANDOVER BETWEEN UTRA R6 CELLS AND R7 CELLS

摘要

PROBLEM TO BE SOLVED: To control optimization of handover procedures between universal terrestrial radio access (UTRA) release 6 (R6) cells and UTRA release 7 (R7) cells.SOLUTION: When a WTRU is moving between an R6 cell and an R7 cell, or between R7 cells, a handover is initiated from a source Node-B to a target Node-B. In the R7 cell, the enhanced MAC functionality including flexible radio link control (RLC) protocol data unit (PDU) size and high speed MAC (MAC-hs) segmentation and multiplexing different priority queues is supported. After the handover, a MAC layer and/or an RLC layer are reconfigured or reset on the basis of functionality supported by the target Node-B.
