Abstract
A wireless communication device (100) can be handed off while operating in the slotted mode of a CDMA system. The wireless communication device comprises a receiver searcher (109) that measures the signal strength of an active pilot prior to the assigned slot and at least one of a plurality of neighbor pilots during an assigned slot. Receiver fingers (107) demodulate a Paging Channel of the active pilot during an assigned slot and can also determine signal strength of pilots simultaneously with the receiver searcher. A Hot Neighbor List is used to prioritize the order in which neighbor pilots are scanned. A logic and control circuit (113) determines if neighbor pilots should be scanned beyond the assigned slot, if the Hot Neighbor List should be modified, and if the wireless communication device should be handed off to another pilot.
