FORWARD LINK DATA SERVICE APPARATUS AND METHOD OF HANDOFF TERMINAL OF CDMA SYSTEM

摘要

PURPOSE: A forward link data service apparatus and method of a handoff terminal of a CDMA system are provided to improve a reception detection performance and heighten a data transfer rate by reducing an influence of an interference signal between sectors belonging to an active set through scheduling between sectors belonging to the active set. CONSTITUTION: When a terminal 'A' is selected(511), an alpha sector scheduler checks whether itself can transmits a packet by using a data received from an arbiter of a memory storing an idle sector(513). If the alpha sector scheduler recognizes that itself has not been stored through the arbiter of the memory storing the idle sectors, the alpha sector scheduler observes an active set of the terminal 'A' that itself is going to do a service(517). If there is a different sector in the active set of the terminal, the alpha sector scheduler requests an idle sector registration from the arbiter of the memory storing the idle sector. The memory arbiter updates the idle sector according to the idle sector registration request of the alpha sector scheduler(519). The memory arbiter informs each sector scheduler of the data on the updating of the idle sector. When the alpha sector scheduler receives the update data, the alpha sector scheduler transmits a packet data to the terminal 'A'(521). When the packet is completely transmitted, the arbiter of the idle sector memory deletes other sector values of the active set remembered before transmitting the packet stored in the idle sector region(523).
