The radio relay station receives downlink radio signals from a stationary base station fixed outside the conveyance, and transmits to destination user equipments in the conveyance downlink radio signals resulting from the downlink radio signals transmitted from the stationary base station. In addition, the radio relay station receives uplink radio signals from multiple user equipments in the conveyance, and transmits to the stationary base station uplink radio signals resulting from the uplink radio signals transmitted from the multiple user equipments. The radio relay station receives from the multiple user equipments auxiliary radio signals indicating a downlink radio signal which the stationary base station has transmitted, detects, within a result of reception of the auxiliary radio signals, a downlink radio signal addressed to a user equipment in the conveyance, and transmits the downlink radio signal to the user equipment."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio relay station","description":"A radio relay station is arranged on a moving conveyance.
