A QoS-based Power Optimization for D2D underlaying Macro-Small Cellular Networks with Imperfect Channel Estimation
The Device-to-Device (D2D) communication underlaying cellular networks generates interference due to reusing the same resources of the conventional cellular network. Therefore, efficient interference management techniques are required to control the interference. In this paper, we address the problem of interference management for underlay D2D users in a two-tier heterogeneous macro-small cell network assuming imperfect Channel State Information (CSI). The optimal power of D2D users that maximize the Signal to Interference and Noise (SINR) ratio is obtained in presence of imperfect CSI. The effect of channel estimation error on the performance of both D2D and cellular users is measured in terms of the achievable rate and the cumulative distribution function (CDF) of the SINR.
