PROJECT TITLE :

LAW: A Novel Mechanism for Addressing Hidden Terminal Problem in LTE-U and Wi-Fi Networks - 2018

ABSTRACT:

Recently, the use of LTE in unlicensed spectrum (LTE-U) has gained a lot of attention. One of the daunting tasks before any such employment was to make sure the fair sharing of unlicensed spectrum between LTE-U and Wi-Fi radio access technologies (RATs), which now looks to be well addressed within the literature. However, along with truthful sharing, the economical utilization of unlicensed spectrum is also of profound significance, which pushes the necessity for coordination between LTE-U and Wi-Fi. Hence, this letter proposes a completely unique LTE-U and Wi-Fi (LAW) inter-RAT coordination mechanism for a a lot of economical utilization of the unlicensed spectrum. The aim is to deal with the inter-RAT hidden terminal downside between LTE-U and Wi-Fi and, thereby, offer better spectral potency. We have a tendency to modify the regular clear-to-send (CTS)-to-self frame and suggest the transmissions of changed CTS-to-self from LTE-U nodes to unravel this hidden terminal issue. More gains are extracted by permitting the simultaneous transmissions of LTE-U and Wi-Fi whenever doable.
