For position determination with peer-to-peer communication, a target terminal (120a) broadcasts a request (1) for assistance in determining its position. At least one ranging terminal (120b, 120c, 120n) receives the request. Each ranging terminal (120b, 120c, 120n) sends a response with a time of arrival (TOA) measurement for the request and the position (3) of the ranging terminal. For two-way peer-to-peer, the target terminal receives at least one response from the at least one ranging terminal, obtains a TOA measurement for each response, estimates the distance to each ranging terminal based on the TOA measurement for the request and/or the TOA measurement for the response, and computes a position estimate (4) for itself based on the estimated distance and the position for each rangingterminal. For one-way peer-to-peer, a network entity receives at least one response from the at least one ranging terminal, computes a position estimate for the target terminal, and sends the position estimate to the target terminal.
