Device-to-Device Communication Overlaying Two-Hop Multi-Channel Uplink Cellular Networks

  title={Device-to-Device Communication Overlaying Two-Hop Multi-Channel Uplink Cellular Networks},
  author={Jiajia Liu and Nei Kato},
Different from previous works, in this paper, we adopt D2D communication as a routing extension to traditional cellular uplinks thus enabling a two-hop route between a user and the serving BS via a D2D relay. Specifically, a BS establishes a cellular link with a mobile user only if the pilot signal strength received from the user is above a specified threshold; otherwise, the user may establish a D2D link with a neighboring user and connect to a nearby BS in a two-hop manner. We present a… CONTINUE READING
