Claim 10:
11. A Wireless Transmit/Receive Unit (WTRU), comprising:
a transceiver configured to receive from a Network Access Point (NAP), configuration information indicating a set of preambles and corresponding propagation-delay thresholds; and
a processor configured to:
determine propagation-delay information associated with a distance between the WTRU and the NAP or a location in a coverage area of the NAP,
