Position determination using time difference of arrival of single frequency network signals

A receiving terminal for a wireless communication network, the receiving terminal comprising:

• interface circuitry configured for communication with the wireless communication network;
• and
• processing circuitry operatively coupled to the interface circuitry and configured to:
• receive, in a first time period, two or more variations of the positioning signal, the two or more variations of the positioning signal being transmitted synchronously by respective ones of two or more base stations as a single frequency network (SFN) signal to effect one or more time shifts at the receiving terminal between different ones of the variations of the positioning signal;
• and
• detect time positions of impulses in a first composite channel impulse response of the SFN signal transmitted in the first time period, the impulses corresponding to the two or more variations of the positioning signal.

A base station for a wireless communication network, the base station comprising:

• interface circuitry configured for communication with a receiving terminal in the wireless communication network;
• and
• processing circuitry operatively coupled to the interface circuitry and configured to:
• generate a first variation of a positioning signal to be transmitted as a single frequency network (SFN) signal to effect one or more time shifts at the receiving terminal between the first variation of the positioning signal and one or more different variations of the positioning signal transmitted synchronously by one or more other base stations;
• and
• transmit, in a first time period as the SFN signal, the first variation of the positioning signal synchronously with the one or more different variations of the positioning signal transmitted by the one or more other base stations.
