PROJECT TITLE :

Full-duplex transmission in phy and mac layers for 5G mobile wireless networks

ABSTRACT:

As the fourth-generation (4G) standards have been successfully deployed in all 4G-based wireless communication industries and mobile devices, analysis attention and the efforts of academia and industry have already moved onto fifth-generation (5G) technologies. While the frequency-division duplexing (FDD) and timedivision duplexing (TDD) are widely employed in 4G mobile wireless networks, they need their inherent deficiencies of low spectrum potency as a result of FDD and TDD are both primarily based on the half-duplex transmission mode. To beat these issues existing in 4G systems, in this text we have a tendency to propose novel wireless full-duplex transmission schemes in both the PHY and MAC layers for 5G mobile wireless networks to significantly increase the spectrum efficiency. In specific, we have a tendency to 1st develop the wireless fullduplex model for both bidirectional transmission and unidirectional transmission, respectively, taking under consideration self-interference mitigation. Then we analyze the traditional 0.5-duplex FDD and TDD modes and show the superiority of the wireless full-duplex mode over the halfduplex FDD and TDD modes, respectively. Using our developed wireless full-duplex model, we develop and evaluate the efficient full-duplex power allocation theme at the PHY layer. Corresponding to full-duplex transmission at the PHY layer, we conjointly develop and analyze the fullduplex MAC protocol at the MAC layer to implement full-duplex transmission over the whole 5G mobile wireless network design. Through simulation experiments we have a tendency to show that our proposed schemes will significantly enhance spectrum efficiency for 5G mobile wireless networks.
