摘要：

In this letter, we study a classic three-node relay network with two end nodes and one relay. A unified signal model is proposed to represent four typical relay modes, namely, one-way half-duplex, two-way half-duplex, one-way full-duplex, and two-way full-duplex. This unified model is then applied to conveniently formulate the sum data rate of a multicarrier relay network with hybrid relay modes on a per subcarrier basis. Joint relay mode selection and power allocation method is developed under individual node power constraint, with the aim to maximize the sum data rate of the two end nodes.
