Abstract
A base station (101) supports a remote station (117) making uplink transmissions using an uplink scrambling code in a first cell. A controller (119) determines a set of uplink scrambling codes from an identity of the remote station (117) and selects the used code therefrom. An access point (111) determines the group of remote stations registered at the access point. A measurement code processor (205) determines the uplink scrambling codes potentially used by the remote stations. A measurement unit (207, 209) then monitors for received signals using these codes and a handover detection processor (211) generates a potential handover detection for the remote station (117) in response to a detection of a received signal using the uplink scrambling code of the remote station (117).
