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: Techniques for unifying split bearers at user equipment (UE) in an Evolved-Universal Terrestrial Radio Access-New Radio (E-ULTRA NR) dual connectivity (EN-DC) environment are described. According to various such techniques, a radio resource control (RRC) message can include an encapsulated configuration for a secondary cell group (SCG). Packet data convergence protocol (PDCP) configurations for MN or SN split bearers can be included in the master cell group (MCG) configuration in the RRC message or in the encapsulated SCG configuration. In some examples, an RRC message can include an encapsulated SCG configuration and an encapsulated PDCP configuration, where the encapsulated PDCP configuration including PDCP configuration information for the MN or SN split bearer. Other embodiments are described and claimed.

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: 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: Embodiments of a next generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. A gNB may be configurable to operate as a master gNB (MgNB). The MgNB may transmit radio-resource control (RRC) signaling to provide information for dual connectivity to allow the UE to utilize radio resources of both a master cell group (MCG) associated with the MgNB and a secondary cell group (SCG) associated with a secondary gNB (SgNB). The MgNB may transmit, to the SgNB, an SgNB release request message that indicates a partial suspension of the dual connectivity, wherein: a first portion of a configuration for the SCG is to be maintained and a second portion of the configuration for the SCG is to be released.

Abstract: Embodiments of a generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may receive, from the UE, a first measurement report that indicates a first signal quality measurement based on new radio synchronization signals (NR-SS). The gNB may determine, based on reception of the first measurement report, a transmission direction for transmission of channel state information reference signals (CSI-RS) for a second RRM measurement at the UE based on the CSI-RS. The gNB may receive, from the UE, a second measurement report that indicates a second signal quality measurement based on the CSI-RS. The gNB may determine, based at least partly on the first and second signal quality measurements, whether to initiate a handover of the UE from a serving cell to a neighbor cell.

Abstract: Apparatuses, systems, and methods for a handling uplink listen before talk (LBT) procedure failures in unlicensed bands of 5G NR. A wireless device may count a number of failed transmissions due to LBT procedure failures, e.g., that may occur in one or more transmit/receive occasions. The wireless device may determine that the count has met a threshold, e.g., that a number of failed transmissions has reached the threshold. The wireless device may initiate a recovery procedure based on determining that the count has met the threshold.

Abstract: Systems and methods are provided for increasing paging opportunities when the unlicensed band is used. A user equipment (UE) may determine a plurality of different paging occasions (POs) to monitor per DRX cycle. The plurality of different POs corresponds to beam sweep repeats for a first set of UEs in an unlicensed band from a base station in a wireless network. The UE monitors the plurality of different POs to receive the paging message from the base station. The plurality of different POs may include respective physical downlink control channel (PDCCH) monitoring occasions. The plurality of different POs may include at least two consecutive POs associate with the first set of UEs within a same paging frame. Alternatively, the plurality of different POs may include at least two non-consecutive POs associated with the first set of UEs separated by at least cycle one other PO associated with a second set of UEs.

Abstract: A Next Generation Node-B (gNB) and methods of communication are generally described herein. The gNB is configurable to operate as a source gNB. The gNB is configured with logical nodes including a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU comprises a gNB-CU control plane (gNB-CU-CP) for control-plane functionality, and a gNB-CU user plane (gNB-CU-UP) for user-plane functionality. When a handover of a User Equipment (UE) from the source gNB to a target gNB is performed, the gNB transfers, from the gNB-DU to the gNB-CU-UP, a downlink data delivery status (DDDS) message to indicate that the gNB-CU-UP is to stop transfer, to the gNB-DU, of downlink data intended for the UE.
