Abstract: Abstract Device-to-device (D2D) communications in the long term evolution (LTE) Advanced (LTE-A) cellular system are investigated. The objective is to form collaborative D2D groups for transmitting/receiving data in the uplink (UL) and downlink (DL) in an energy efficient manner. The energy minimization problem using multihop D2D is formulated as a binary integer linear program. A low complexity suboptimal solution method is proposed, and shown to lead to good performance, especially in the low complexity 1-hop D2D scenario. The investigated framework is applicable to both public safety (PS) and non-PS scenarios. In addition to significant energy savings, the proposed method is shown to lead to reduced delays and enhanced quality of service (QoS), especially when real-time video transmission is considered.
