Abstract

A cellular communication system includes base stations supporting macro cells and with unique cell scrambling codes within a region. The system further includes access points supporting underlay cells and with shared cell scrambling codes within the region. One or more of the access points or base stations comprise transmit means for transmitting an indication of at least a first shared scrambling code to a remote station. The shared scrambling code is shared by a plurality of access points. The remote station is arranged to receive the first shared scrambling code and to determine if a first signal using the first shared scrambling code is received. If the first signal is detected, a handover controller initiates a handover of the remote station to at least a first access point of the plurality of access points sharing the first shared scrambling code.
