Patent ID: 8437308

Claim:
A method performed by a user equipment operating in a mobile communication system that comprises equipment for serving a plurality of geographic cells and having an air interface that is divided into sequentially occurring frames, wherein each of the frames consists of a plurality of sub-frames at least two of which are synchronization sub-frames, wherein for each of the cells served by the mobile communication system, a respective one of a plurality of cell-related synchronization signals is transmitted to user equipments in the at least two synchronization signal sub-frames of every frame, the method comprising: detecting a cell identity of a first cell in the mobile communication system; detecting a cell identity of a second cell in the mobile communication system; using a plurality of weights to control generation of a plurality of weighted handover measurements made from the first cell's synchronization signals received during a plurality of synchronization sub-frames, wherein the plurality of weights are applied to measurements made for the first cell during respective ones of the plurality of synchronization sub-frames, and wherein each of the weights is a function of the cell identity of the first cell, the cell identity of the second cell, and which ones of the first and second cells' cell-related synchronization signals are transmitted in the respective one of the plurality of synchronization sub-frames during which the weight is applied; generating a filtered handover measurement from the weighted handover measurements; and providing the filtered handover measurement to a handover process that uses the filtered handover measurement to control a handover process involving the user equipment.
