D2D neighbor discovery interference management for LTE systems

Abstract

Direct Device-to-Device (D2D) communications in cellular systems has attracted a lot of interest for both commercial and public safety applications. To support D2D communications, a first step involving neighbor discovery is typically needed. This paper focuses on the study of neighbor discovery signal design aspects and interference management for D2D discovery under a typical LTE system deployment. System level results on detection rate and range comparing different interference management techniques are provided. The results indicate that practical interference management techniques have the potential to improve the performance of neighbor discovery for cell-edge devices significantly.
