    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.

    Abstract: Devices, methods, user equipment (UE), base stations, storage media, and other embodiments are provided for a dynamic random access channel (RACH). In one embodiment, an apparatus includes a memory configured to store a configuration communication from a base station, the configuration communication comprising a dynamic dedicated random access channel (RACH) configuration (RACH-ConfigDedicated) information element, the RACH-ConfigDedicated information element comprising a plurality of dedicated random access parameters. Processing circuitry coupled to the memory is then configured to decode the configuration communication from the base station to identify the plurality of dedicated random access parameters and set up a RACH procedure for connection to the base station using the plurality of dedicated random access parameters. In various embodiments, different communications may be used for the dedicated random access parameters which are used in the RACH procedure.

    Abstract: Apparatuses for partially offloading processing from a user equipment (UE) to a cellular Radio Access Network (RAN) node are disclosed. An apparatus for a UE includes at least one processor configured to perform Transmission Control Protocol and Internet Protocol (TCP/IP) processing and offload only a portion of the TCP/IP processing to a cellular RAN node while maintaining TCP protocols running end-to-end between the UE and a remote host.
