Query: Wireless Full-duplex Medium Access Control for Enhancing Energy
  Efficiency   Recent years have witnessed a proliferation of battery-powered mobile
devices, e.g., smartphones, tablets, sensors, and laptops, which leads a
significant demand for high capacity wireless communication with high energy
efficiency. Among technologies to provide the efficiency is full-duplex
wireless communication. Full-duplex wireless enhances capacity by
simultaneously transmitting uplink and downlink data with limited frequency
resources. Previous studies on full-duplex wireless mostly focuses on doubling
the network capacity, whereas in this paper we discuss that full-duplex
wireless can also provide higher energy efficiency. We propose low power
communication by wireless full-duplexing (LPFD), focusing on the fact that the
full-duplex communication duration becomes half of the halfduplex communication
duration. In the LPFD, by using the sleep state in which the transceiver
provided in the wireless communication terminal is turned off, power
consumption of the wireless communication terminal is reduced and energy
efficiency in wireless full duplex is improved. Simulation results show that
the energy efficiency achieved by LPFD is up to approximately 17.3 times higher
than the energy efficiency achieved by existing full-duplex medium access
protocol. Further, it is up to approximately 27.5 times higher than the energy
efficiency using power saving mode of half-duplex communication.
