A wireless positioning method uses a time window duration derived from timing information of two access stations to coordinate measurement procedures for UE localization.

Patentradars sammanfattning

The invention relates to positioning of wireless devices (UEs) in a cellular network by defining a Time Window Duration (TWD) for a first Access and Control Station (ACS) based on comparative timing information between a first and a second ACS. A UE obtains information indicating this TWD and performs positioning measurements—such as RSTD or TDOA measurements—within a first window period defined by the TWD. This approach synchronizes measurement windows to the relative timing relationships between access stations, improving positioning accuracy and measurement efficiency.
