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: In embodiments, apparatuses, methods, and storage media may be described for monitoring channel quality of a radio link between a secondary evolved NodeB (SeNB) and a user equipment (UE) in a wireless communication network configured for dual connectivity. In embodiments, the UE may generate one or more indications of a channel quality of the SeNB-UE radio link and forward the indication to the SeNB. Based on the indication, the UE may receive a radio resource control (RRC) message from a master eNB (MeNB) related to the SeNB-UE radio link. Other embodiments may be claimed.

Abstract: In accordance with some embodiments, a user equipment or mobile station may provide assistance to the eNB or base station so that eNB or base station can more effectively provide settings to the user equipment. Because the user equipment may have more in depth knowledge about the conditions that exist at the user equipment, efficiencies may be achieved by providing information to the eNB from which the eNB can better set various settings on the user equipment, including those related to power saving and latency.

Abstract: Systems and methods provide resource allocation signaling for low cost machine type communication (LC-MTC) devices with the elimination of the physical downlink control channel (PDCCH) in long term evolution (LTE) communication systems. Disclosed systems and methods provide alternative light-weight, efficient control signaling for resource allocation of LC-MTC devices.

In one embodiment, for example, user equipment (UE) may comprise logic, at least a portion of which is in hardware, the logic to receive a radio resource control (RRC) configuration message during operation in a dually-connected UE state, determine whether UE assistance information reporting is enabled for the UE based on the RRC configuration message, and in response to a determination that UE assistance information reporting is enabled for the UE, send one or more UE assistance information messages to report a macro cell power preference and a small cell power preference. Other embodiments are described and claimed.

Other embodiments are described and claimed.

Abstract: Systems and methods are disclosed for communicating enhanced user equipment (UE) assistance information between nodes in wireless communication systems. The UE achieves power savings and latency requirements more effectively by communicating its preferences, constraints and/or requirements to an evolved Node B (eNodeB) in the form of UE assistance information. The UE assistance information may include, for example, an indication of a preferred set of discontinuous reception (DRX) settings, current data traffic conditions, expected data traffic conditions, power or performance preferences, and/or an indication of the UE's mobility between cells.

Abstract: Technology for a user equipment (UE) operable to determine a power preference indication (PPI) is described. The UE can determine the PPI as one of a low power consumption or a normal power consumption. The UE can start a PPI timer when the PII is set for the normal power consumption. The UE can encode the PII for transmission to an Evolved Universal Terrestrial Radio Access Network (EUTRAN) in a UE assistance information message.
