Abstract
Systems and methods relating to coexistence of a cellular communications network technology (e.g., Long Term Evolution (LTE)) and another wireless technology (e.g., WiFi) in a shared unlicensed spectrum are disclosed. In particular, the present disclosure provides systems and methods that mitigate or avoid grabbing of an unlicensed, or shared, frequency band utilized by a wireless communications network node by a node of another wireless technology that operates according to a listen-before-talk scheme.
