Timing adjustment method, receiving station, and transmitting station in wireless communication system, and wireless communication system

A wireless communication system wherein signals are transmitted and received between a first radio station and a second radio station, comprising:

• the first radio station including:
• a measurer that measures a difference between a reference timing of the first radio station and a reception timing of a signal transmitted from the second radio station;
• a timing adjustment signal generator that generates a first signal including data on the difference;
• and
• a transmitter that transmits the first signal including the data on the difference;
• and
• the second radio station including:
• a signal generator that generates a second signal in a time domain using an orthogonal transformation;
• a timing adjustment signal extractor that extracts the data on the difference included in the first signal transmitted from the first radio station, as extracted difference data;
• a transmission timing controller that determines a correction amount of a signal arrangement phase and that of a transmission timing based on the extracted difference data;
• a phase controller that controls the signal arrangement phase of the second signal in the time domain based on the correction amount of the signal arrangement phase;
• and
• a timing adjustor that controls the transmission timing of the second signal in which the signal arrangement phase is controlled based on the correction amount of the transmission timing, and
• wherein using the controlled transmission timing, the second radio station transmits the second signal to the first radio station.
