Abstract:
A base station site synchronized cellular communications system, wherein downlink control channel transmission are allocated on discontinuous control channel carrier, comprising:a first base station; a second, neighboring base station; and a mobile station being served by the first base station, the mobile station including a measurement unit adapted to make measurements of control channel signaling of the neighboring base station, wherein the measurement unit: identifies a time slot during which the neighboring base station transmits control channel signaling, defines a duration of a control channel signaling measurement window to be less than a duration of the identified timeslot, aligns the control channel signaling measurement window such that the measurements of the control channel signaling from the neighboring base station actually arrives at the measurement unit of the mobile station, and adjusts the position of the measurement window based on a determination of an absolute time reference from the first base station.
