METHOD AND SYSTEM FOR PROVIDING A POWER-EFFICIENT SOFT HANDOFF IN A MULTICARRIER CDMA CELLULAR SYSTEM

摘要

The present invention relates to a method and system for supporting a power-efficient handoff in a multi-carrier code division multiple access cellular system, wherein a mobile station user soft-offs from one base station to an adjacent base station in a multi-carrier code division multiple access cellular system. A mobile station of a multi-carrier code division multiple access system for receiving and communicating different system user information from multiple base stations adjacent to a handoff area at the same time to perform handover includes an apparatus for determining a handoff start and information of the adjacent base station. A device for providing handoff request information and a receiving device for combining and demodulating received signals of different frequencies received from a plurality of base stations, wherein the base station controller includes a plurality of base stations in the handoff area according to the handoff request information of the mobile station; to And a device for dividing and assigning the plurality of carrier frequencies, wherein the base station apparatus includes a signal transmitter for transmitting other system user information only to the assigned carrier according to the carrier assignment of the base station controller. The power of the base station wasted during handoff can be reduced, ultimately increasing the subscriber capacity of the entire cellular system.
