Abstract: Embodiments of a User Equipment (UE), Evolved Node-B (eNB) and methods of communication are generally described herein. The UE may receive a SystemInformationBlockType1 from an eNB. The UE may determine that the eNB supports Fifth Generation Core (5GC) operation if the SysteminformationBlocklType1 message includes a plmn-Identity-5GC-r15 parameter. The UE may transmit a radio resource control (RRC) connection request message to establish an RRC connection. If it is determined that the eNB supports 5GC operation, and if the UE supports 5GC operation, the UE may encode the RRC connection request message in accordance with a default new radio packet data convergence protocol (NR PDCP) configuration; and may use NR PDCP for one or more subsequent messages.

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: An apparatus of an evolved Node B or a Fifth Generation Node B comprises one or more baseband processors to generate an RRCConnectionReconfiguration message to include an information element (IE) to configure a user equipment (UE) to receive data from a Long-Term Evolution node and from a New Radio node in a unified split bearer configuration and encode data to be transmitted to the UE via a master cell group bearer, a secondary cell group bearer, or a unified split bearer. The baseband processors further are to encode an IE of an RRCReconfiguration message to configure a data radio bearer as a Packet Data Convergence Protocol and higher layers configuration coupled with one or more logical channels of radio link control and below, and to configure a change between a single connectivity bearer to multi-connectivity bearer by configuring or releasing one or more of the logical channels.

Abstract: A secondary node (SN) in evolved universal mobile telecommunications system terrestrial radio access network new radio-dual connectivity (EN-DC) with a master node (MN) can directly provide measurement configuration and receive measurement reports from a UE and/or coordinate measurement configuration and reporting with the MN. For example, only one measurement object configuration is allowed for a frequency, but both MN and SN can provide measurement reporting configurations on the same measurement object. The UE can send measurement reports for the same measurement object to both MN and SN or the node that configured the reporting criteria configuration. In another embodiment, only one node provides the reporting configuration but configures the UE to provide reporting to one node or both MN and SN.

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: Systems and methods of providing feedback when a specific PDU is successfully delivered or transmitted are described. The node hosting PDCP entity indicates triggering of a DDDS frame from the remote corresponding node. Rather than immediately triggering transmission of a DDDS frame, the node hosting PDCP entity indicates triggering based on successful delivery of a PDU having a specific SN, as long as in-sequence delivery or transmission of PDUs up to the specific SN was successful. The DDDS frame is transmitted once the corresponding node determines that the PDU having the SN was successfully delivered or transmitted. After reporting by the DDDS frame, the QoS flow associated with the PDUs is remapped from a source DRB to a target DRB.

Abstract: Systems and methods of optimizing NR RRC connection establishment are described. The UE transmits a RRC request for establishment of a connection to a gNB.

A response from the gNB is received and acknowledged using the SRB1 or a SRB1 having a SRB1 configuration provided in the response. The RRC request is a RRCReestablishmentRequest or RRCResumeRequest.
