Radio relay system, radio relay apparatus and radio relay method

摘要

A radio relay system is disclosed that is capable of preventing communication degradation in a case where radio signals are relayed using the same frequency band in a mobile communication environment. The radio relay system includes a first radio station, a second radio station, and a radio relay apparatus for relaying a radio signal that is exchanged between the first radio station and the second radio station. The radio relay apparatus includes a phase correction determining unit that determines a phase correction amount of the relayed signal based on channel information pertaining to channels established between the first radio station, the second radio station, and the radio relay apparatus, and a phase correction unit that corrects the relayed signal based on the phase correction amount determined by the phase correction determining unit.
