In this paper, Pareto optimal multi-user transmission scheduling in a system comprising of one source, one relay, and two destinations is discussed. To achieve proportional fairness among users in multi-user case, a scheduling scheme for a hybrid of full- and half-duplex relaying (FHDR) is proposed in this paper, which extends a transmission scheduling for(More)
— In mobile multihop communications, diversity technique is important since the channel between mobile terminals may suffer from effects of fading and the routes between terminals are normally created through several hops. Space-time code using multiple transmit antennas is effective countermeasure for fading. For terminals which have only one antenna due(More)
This paper proposes a Multi-hop Radio Access Cellular (MRAC) scheme for achieving both high-speed/high-capacity and good area coverage in fourth generation mobile communications systems. In this scheme, we assume two kinds of hop stations, one is a dedicated repeater station installed at a good propagation location such as a rooftop, and the other is a user(More)
