Interference reduction by switching the underlaying transmitter in D2D communications

Enabling the device-to-device (D2D) communication in the cellular network (CN) induces the problem of interference. This paper proposes a scheme of controlling the power of the D2D user equipments (DUEs) by switching D2D transmitter on the basis of receiver-sensitivity. The performance of the proposed scheme has been evaluated in slow fading environment, with the assumptions that the proximity gains, instantaneous gains between base station (BS) and mobile user equipments (UEs) is available at the BS and that the D2D users (DUs) are moving slowly. It has been shown that the cell sum-rate increases significantly compared to conventional CN infrastructure without degrading the performance of the cellular users.
