SOFT HANDOVER METHOD IN CDMA COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a soft handover method reduced in a downlink interference amount and excellent in a communication quality. SOLUTION: In the soft handover method in a CDMA communication system for revising a base station apparatus to which a mobile communication terminal is connected through software control, before the mobile communication terminal starts a handover sequence, it is estimated that a downlink signal has already been transmitted to the base station apparatus being a handover destination, and Rake synthesis between the downlink signal and the downlink signal of the base station apparatus being a handover source is started.
