Power allocation of two-way device-to-device relays underlay cellular network

In this paper,we assume that a device-to-device (D2D) bidirectional relay network is deployed in a cellular network.Each D2D two-way relay is equipped with two transmit antennas,which are respectively carried out at the same time with base station and receiver.Under the assumption that D2D two-way relay adjust power transmission amplification,we propose a power allocation scheme of the two-way relay network.The simulation results show that the scheme proposed can obtain larger two-way relay network throughput than the random power allocation and the traditional communication methods
