Radio relay station apparatus and radio relay method

摘要

To provide a radio relay station apparatus and radio relay method for enabling the radio relay station apparatus to identify a multi-hop relay signal and relay a downlink signal suitably, a first radio relay station apparatus or a radio base station apparatus generates a control signal indicative of passing through a radio relay station apparatus, and transmits the control signal in downlink, and a second radio relay station apparatus receives the control signal, demodulates a downlink signal based on the control signal, modulates the demodulated downlink signal, and transmits the modulated downlink signal.

主权项

1. A radio relay station apparatus having a processor, the processor comprising:
a reception section configured to receive a control signal that indicates whether or not a data signal of downlink is passed through another radio relay station apparatus; a demodulation section configured to demodulate data signals of downlink from a plurality of propagation paths; a combining section configured to combine the data signals of downlink based on the control signal; a modulation section configured to modulate the data signals of downlink subjected to combination; and a transmission section configured to transmit the data signals of downlink subjected to modulation.
