Making time of arrival measurements

摘要

A time of arrival measurement apparatus is used to measure the time of arrival of a radio signal transmitted by a mobile communication station operating in a wireless mobile communication network. The apparatus is provided with information indicative of a predetermined point in time at which the radio signal is to be transmitted. The time of arrival measurement apparatus monitors for arrival of the radio signal only during a period of time after the predetermined point in time. The time of arrival measurement apparatus also receives information from which it can determine an informational content of the radio signal.
