Abstract

Communication device comprising circuitry configured to measure a first phase of a first measurement signal transmitted by a first node to a second node, measure a second phase of a second measurement signal transmitted by the second node to the first node, repeat the measurements of the first and second phases one or more times, receive phase information from the first node and/or the second node, the phase information including third phase information acquired by the second node from measurements of a third phase of the first measurement signals and/or fourth phase information acquired by the first node from measurements of a fourth phase of the second measurement signals, and estimate a distance difference using the measured first and second phases and the received phase information.
