Abstract
In a Device-to-Device (D2D) underlaying cellular system, interference cancellation is a key problem when uplink spectrums are shared and this problem becomes more complex in a multi-cell cellular network. In this paper, we propose an effective near-far interference avoidance scheme in a multi-cell cellular system. After monitoring the related control channels of a D2D subsystem and exchanging necessary information among neighboring eNBs, an eNB may stop scheduling the interfering cellular devices or facilitate power control mechanisms for the victim D2D users such that the inter-cell near-far interference can be mitigated. Simulations prove that our mechanism is effective and satisfying performance improvement can be obtained.
