Power Adaption for Half-Duplex Relay-Based D2D Communication Underlaying Cellular Network

摘要

The existing half-duplex relay-based device-to-device (D2D) communication equips with single antenna infrastructure and receives and transmits signals in two equivalent slots which lead to poor performance in term of rate achievement. To solve this problem, we propose a new relay-based D2D scheme with two-antenna infrastructure and bring in slot splitting factor to divide one frame into double unequal slots. The simulation results show that the proposed relay-based D2D communication scheme outperforms the existing half-duplex and full-duplex relay-based D2D communication in term of achievable rate.
