    Abstract: A cellular wakeup receiver (C-WuRx) for reducing power consumption of a wireless wide area network (WWAN) radio of a user equipment (UE) includes receiver circuitry to receive a wakeup signal from a base station in response to the UE performing link aggregation by which downlink communications from the base station are offloaded to a wireless local area network (WLAN). The C-WuRx also includes processing circuitry to configure the receiver circuitry to periodically monitor at least a portion of a WWAN band for the wakeup signal and process the wakeup signal to cause the WWAN radio to resume receiving the downlink communications from the base station.

    Abstract: Technology described herein provides systems and technologies that help avoid waste of wireless network resources due to frequent losses of wireless connectivity with energy-harvesting devices (EHDs). An energy-harvesting-indicator communication can be sent from a wireless device to a cellular base station to inform the cellular base station that the wireless device is an EHD. The cellular base station can preserve context information and/or DL data pertaining to a wireless connection with the EHD when a wireless connection is lost due to a temporarily low level of available energy at the EHD. The context information and/or DL data can be preserved by the cellular base station until the period of time elapsed exceeds a threshold time value. Upon receiving a connection-resumption communication from the EHD, the cellular base station can use preserved context information to restore the wireless connection and proceed to send preserved DL data to the EHD.
