THRESHOLD DETERMINATION IN TDOA-BASED POSITIONING SYSTEM
摘要
A method in a wireless communication terminal including receiving a signal comprising at least a Positioning Reference Signal (PRS) transmission from a serving cell and a PRS transmission from a neighbor cell, estimating a signal quality metric (SQM) based on the PRS transmission from the neighbor cell, estimating a time difference of arrival (TDOA) measurement for the neighbor cell based on the PRS transmissions, determining if the estimated SQM satisfies a criterion, and sending a report to the serving cell that includes at least the estimated TDOA if the criterion is satisfied.
