  • Publication number: 20220256436
    Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for the reduction of handover interruptions. Some embodiments include a user equipment (UE) that supports simultaneous connectivity with a source 5G Node B (gNB) and a target gNB during a handover. Some embodiments include the UE receiving source path data packets from the source gNB and target path data packets from a target gNB. The UE performs a first reorder of the one or more source path data packets and the one or more target path data packets by sequence number (SN), and the UE performs header decompression on the reordered source path data packets, separately from the reordered target path data packets. After the header decompressions the UE performs a second reorder of the source path data packets and the target path data packets together by SN, and discards any duplicate data packets based on SNs.

  • Publication number: 20220191733
    Abstract: Methods and systems are provided to indicate assistance information for radio access technologies to support interface selection for New Radio (NR) Vehicle-to-Everything (V2X) processes. An upper layer entity exchanges information with lower layer entity while the upper layer can continue to use the existing interface for V2X transmission until it is not able to use the current interface. The upper layer can be a V2X layer and the lower layer can be an Access Stratum (AS) layer. The upper layer can request availability information from the lower layer for other applicable interfaces. The upper layer then instructs the lower layer to provide assistance information for one or more applicable interface(s), depending on whether mapped to the ongoing service. In providing availability information, the lower layer can continuously measure criteria, such as channel conditions, to determine the availability of relevant interfaces and indicate the availability information to the upper layer.

  • Patent number: 11337062
    Abstract: Embodiments have a master eNB with a control plane and optional data plane to user equipment and a secondary eNB with a data plane to the user equipment. The user equipment thus uses both the master eNB and the secondary eNB for data communications while receiving control information from only the master eNB. The master eNB and secondary eNB are connected with an X2 interface. When the secondary eNB desires to refresh its security key, it informs the master eNB using the X2 interface. The master eNB then uses its control plane with the user equipment to initiate a security key refresh for the secondary eNB.
