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 the present disclosure describe methods, apparatuses, storage media, and systems for adequate failure secondary cell group (SCG) reporting in New Radio (NR) involved networks. Various embodiments describe how to generate a sufficient SCG failure report so that a master node (MN) in the network may acknowledge the corresponding failed reference signal including its frequency and subcarrier spacing. In accordance, the MN may configure the UE and network communication effectively. Other embodiments may be described and claimed.

Abstract: Briefly, in accordance with one or more embodiments, user equipment (UE) comprising circuitry to connect to a network via a serving cell; and indicate to the network a measurement gap capability of the UE. The measurement gap capability includes information if the UE supports a carrier aggregation (CA) specific measurement gap and if the UE has two or more radio-frequency (RF) chains. The UE then receives a CA specific measurement gap configuration from the network for the two or more RF chains.

Abstract: A service device (e.g., a user equipment (UE), or other network component) can operate to generate sidelink communications with peer UE vehicle-to-vehicle devices based on PC5 channel to enable a peer-to-peer communication as part of PC5 vehicle-to-everything (V2X) communications. An admission control scheme or a congestion control scheme can be enabled by determining a configured mapping based on various criteria, including a priority of V2X services, V2X packet Quality of Service (QoS) indications per packet, or other criteria. A UE can determine whether a packet is authorized via the sidelink channel based on the configured mapping.

Abstract: Techniques discussed herein can facilitate configuration by a network of one or more measurement gaps based at least in part on UE (User Equipment) assistance. One example embodiment employable by a UE (User Equipment) comprises a memory interface; and processing circuitry configured to: generate UE capability information that comprises, for each measurement scenario of one or more measurement scenarios, an indication of whether the UE is capable of non-gap measurement in connection with that measurement scenario, wherein each measurement scenario applies to one or more associated serving frequencies and one or more associated measurement objects; and process configuration signaling that comprises, for each measurement scenario of the one or more measurement scenarios, an associated indication of whether an associated measurement gap is configured for that measurement scenario.

Abstract: Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to determine that the UE is in an Inactive Radio Resource Control (RRC) state. The second circuitry may be operable to process a first transmission received by the UE while the UE is in the Inactive RRC state, the first transmission carrying a set of one or more Access Control (AC) parameters. The third circuitry may be operable to regulate the sending of a second transmission, in accordance with the set of one or more AC parameters, while the UE is in the Inactive RRC state.

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 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.
