  • transmitting signals by the subscriber stations using default transmission timing offsets;

    receiving said signals by the base station;

    detecting various multipath components of said signals by said base station; and

    when the base station determines that a subscriber station needs to change its transmission timing offsets, transmitting to said station a message identifying a new timing offset, based on the detected multipath components.
