RELAY STATION, RELAY METHOD, RADIO COMMUNICATION SYSTEM, AND RADIO COMMUNICATION APPARATUS

摘要

A relay node in a mobile communication network for relaying communications between a base station and a mobile terminal. The relay node includes a first communication unit that communicates with the base station via a backhaul link using at least one of a first modulation method and a first multiplexing method, and a second communication unit that communicates with the mobile terminal via an access link using at least one of a second modulation method and a second multiplexing method. The relay node also includes a communication control unit that selects the at least one of the first modulation method and the first multiplexing method, or selects the at least one of the second modulation method and the second multiplexing method based on a characteristic of a link, a type of link or a type of data included in a communication signal.

1. A relay node in a mobile communication network for relaying communications between a base station and a mobile station, the relay node comprising:
circuitry configured to: communicate with the base station via a backhaul link and the mobile station via an access link using Orthogonal Frequency Division Multiple Access (OFDMA) and/or Single Carrier-Frequency Division Multiple Access (SC-FDMA),receive a downlink signal from the base station using the OFDMA,
transmit a relayed downlink signal to the mobile station using the OFDMA, receive an uplink signal from the mobile station using the SC-FDMA, and transmit a relayed uplink signal to the base station using the SC-FDMA.
