METHOD AND APPARATUS FOR PROCESSING DATA BLOCKS DURING SOFT HANDOVER

摘要

PROBLEM TO BE SOLVED: To solve the problem that re-ordering of successful transmissions cannot be accomplished since a complete set of successful transmissions may not be available within any one of Node-Bs in a soft handover macro-diversity operation.SOLUTION: A method and apparatus for processing data blocks during soft handover is a wireless communication system which includes at least two enhanced uplink soft handover Node-Bs and a radio network controller (RNC). Each Node-B decodes a received data block and forwards the decoded data block to the RNC. When the RNC receives at least one copy of a successfully decoded data block, the RNC uses a re-ordering function entity to process the copy of the successfully decoded data block to support successful in-sequence transmission to higher protocol layers. When the RNC receives two or more copies of a successfully decoded data block, the RNC discards the extra successfully decoded data block copies.
