  • Patent number: 10743237
    Abstract: Technology for a user equipment (UE) operable to receive system information change notifications from an eNodeB is disclosed. The UE can receive one or more system information (SI) change notifications that indicate a change has occurred in one or more system information blocks (SIBs). The UE can receive a SIB1 that is associated with a value tag, and the SIB1 can include a bit-map that indicates which of the one or more SIBs include a change. The UE can compare the value tag associated with the SIB1 with a value tag stored at the UE. The UE can obtain scheduling information for the one or more SIBs that include a change according to the bitmap when the value tag associated with the SIB1 does not equal to the value tag stored at the UE. The UE can retrieve the SIBs that include a change using the scheduling information.

  • Patent number: 10716114
    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.

  • Patent number: 10530558
    Abstract: Embodiments of an intra-QCI scheduler and method for assisted intra-QCI scheduling are generally described herein for operating within a wireless access network in which data flows are mapped to bearers using quality-of-service (QoS) class identifiers (QCIs). In some embodiments, the intra-QCI scheduler may classify packets of one or more data flows having a same QCI with a sub-QCI based on intra-QCI classification information received from user equipment (UE). The sub-QCI may indicate a scheduling priority for packets of data flows having the same QCI. The intra-QCI scheduler may schedule packets for downlink transmission over a radio bearer between the eNodeB and the UE based on the sub-QCI. The use of sub-QCIs allows the eNodeB to provide QoS support for data flows of applications that have been mapped to a default bearer.
