Radio Resource Management in Coexistence Scenario of LTE and Wi-Fi Over the Unlicensed Spectrums

The development of wireless broadband access network (WBAN) leads to enhance the insufficiency of unoccupied radio resources. This is quite expected in coming times, wireless cellular technologies and wireless local area networks (WLANs) will work together in coexistence scenario within the alike unlicensed spectrums (USs). Although, two most emerging wireless networks, i.e., Long Term Evaluation (LTE) and Wi-Fi, are available to operate in separate bands, but not to operate in the coexisting scenario, particularly in unlicensed spectrum. Here, we review the challenges that occur as a result of the simultaneous functioning of LTE and Wi-Fi within the alike USs from the angle of radio resource management (RRM). We demonstrate that Wi-Fi can strongly affect by LTE transmissions; thus, the integrated LTE and Wi-Fi requires to be cautiously examined. We introduce few feasible coexistence operations and scopes in coming time which may result in the fruitful allied deployment of LTE and Wi-Fi within the alike USs.
