Abstract
Systems and methods are disclosed for enhancing the power efficiency of low power internet of everything (IOE) devices or user equipments (UEs). A UE or IOE having a low power companion receiver maintains its full power receiver in a sleep state until it receives a wake up indicator from a base station. In response to the wake up signal, the UE or IOE powers up its full power receiver and receives data from the base station. The base station further schedules the wake up signals so as not to collide with control signals expected by UEs or IOEs without low power receivers, or those UEs and IOEs are configured to detect and react to the wake up signals.
