Abstract: A User Equipment (UE) device operates to directly determine a target small cell for access or handover with the assistance of a macro cell network. The UE directly generates the connection and selects which small cell to access from among a subset of small cells chosen of a set of candidate small cells. The UE is provided dedicated assistance information from the evolved node B (eNB) or macro network device. The dedicated assistance information enables the UE to measure data from the candidate small cells within a heterogeneous network environment. The UE shares the measured data and connects directly to the selected small cell for an access or handover operation.

Abstract: Systems and methods of segregating a SDF of a PDU session are described. The UE transmits a NAS message to the network. The NAS message indicates the SDF, the desired QoS, and a segregation indication that requests that the network establish a separate QoS flow for the SDF even if an existing QoS flow is able to support the specific QoS. The SMF decides whether or not to establish the separate QoS flow and updates filters in the UPF as well as providing a response to the UE containing a similar indication. The UE modifies resources related to the PDU session based on the response. The QoS is indicated as a 5QI and GBR or as a QFI of an existing QoS Flow on which the SDF is to be added if the separate QoS is not established. The QFI is in an unencrypted SDAP header of the NAS message.

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.

Abstract: 5G methods and architectures to determine active SCells and their bandwidth parts (BWP) used in carrier aggregation (CA) are disclosed in which activating a BWP for an active SCell is performed initially according to a default value provided in initial radio resource control (RRC) messaging. After initialization, SCells and the SCell BWPs used by the user equipment (UE) are activated by RRC messaging, downlink control information (DCI) or dedicated medium access control (MAC) control elements (MAC CEs) with the initial BWP used for an activated SCell being a default value provided during initialization.

Abstract: Embodiments of a User Equipment (UE) to support dual-connectivity with a Master Evolved Node-B (MeNB) and a Secondary eNB (SeNB) are disclosed herein. The UE may receive downlink traffic packets from the MeNB and from the SeNB as part of a split data radio bearer (DRB). At least a portion of control functionality for the split DRB may be performed at each of the MeNB and the SeNB. The UE may receive an uplink eNB indicator for an uplink eNB to which the UE is to transmit uplink traffic packets as part of the split DRB. Based at least partly on the uplink eNB indicator, the UE may transmit uplink traffic packets to the uplink eNB as part of the split DRB. The uplink eNB may be selected from a group that includes the MeNB and the SeNB.

Abstract: Embodiments of an evolved Node B (eNB) and methods for radio link failure handling for dual connectivity are generally described herein. A method performed by circuitry of a User Equipment (UE) may include connecting, at a UE, to a Master eNB (MeNB) and connecting to a Secondary eNB (SeNB). The method may include determining, at the UE, that one of the connections has a Radio Link Failure and determining at the UE, that the other of the connections remains connected to the UE. The method may include refraining from initiating a Radio Resource Control (RRC) re-establishment procedure while at least one of the connections does not have a radio link failure.

Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing dynamic resource allocation (DRA) of resources for machine-type communication (MTC), as a secondary partition within a system bandwidth. Allocations outside the secondary partition are configured as a primary partition for other than MTC. Apparatuses may perform MTC communications within the secondary partition when DRA configuration information includes allocation information for the secondary partition and the apparatus is configured for MTC. Otherwise, if the apparatus is other than MTC, the apparatus may refrain from performing communications in the secondary partition. Other embodiments are described.

Abstract: Technology for communicating security key information from a macro eNB is disclosed. Security key information associated with the macro evolved node B (eNB) may be determined. The security key information may be used to cipher information communicated at the first eNB. A small eNB may be identified at the macro eNB to generate the security key information associated with the macro eNB for ciphering information communicated at the second eNB. The security key information may be communicated, from the macro eNB, to the small eNB for inter-Evolved Universal Terrestrial Radio Access (EUTRA) evolved node B (eNB) carrier aggregation.
