Abstract: Beamforming measurement techniques based on PSS/SSS are disclosed. An apparatus of a user equipment (UE) can include processing circuitry configured to decode a configuration message from a source serving cell, the configuration message indicating signal selection criteria for cell measurement reporting. A synchronization signal (SS) burst set associated with one or more transmission/reception points (TRPs) within a neighboring cell is decoded, the SS burst set including a plurality of SS blocks. A cell beamforming measurement signal associated with the neighboring cell is generated, based on signal measurements of the SS blocks and the signal selection criteria. A radio resource management (RRM) measurement report message is encoded for transmission to the serving cell, the measurement report message including the cell beamforming measurement signal. A handover command message for initiating a handover to the neighboring cell is decoded, the handover command based on the cell beamforming measurement signal.

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: A user equipment (UE) can include processing circuitry configured to decode system information including access barring parameters for one or more access categories for accessing a cell of a next generation Node-B (gNB). A network access attempt is detected by a control plane layer of the UE that is higher than a Radio Resource Control (RRC) layer. The processing circuitry map s, using a Non-Access Stratum (NAS) layer of the control plane, the network access attempt to at least one access category of a plurality of available access categories based on mapping rules. The processing circuitry performs an access barring check procedure for the mapped at least one access category based on the access barring parameters. Upon determining that access to the cell is not barred, a NAS message is encoded for transmission to an Access and Mobility Management Function (AMF), e.g. an Attach Request message to perform an attach procedure.

Abstract: A user equipment (UE) can include processing circuitry configuring the UE for Dual Connectivity (DC) with a Master Node-B (MN) and a Secondary Node-B (SN). The processing circuitry is to decode connection reconfiguration information received from the MN. The connection reconfiguration information includes signaling radio bearer type 3 (SRB3) configuration information. The SRB3 configuration information originating from the SN and configuring a SRB3, where the SRB3 is for direct communication between the UE and the SN. At least one of a radio resource control (RRC) reconfiguration completion message or a measurement report message is encoded for transmission to the SN.

Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU may determine a route for delivery of a data packet to a User Equipment (UE) on an integrated access backhaul (IAB) of relays. The gNB may generate a physical layer (PHY) data packet in accordance with a split between functionality of a packet data convergence protocol (PDCP) layer at the gNB-CU and functionality of a radio link control (RLC) layer at the gNB-DU. The PHY data packet may include the data packet, a PDCP header, an adaptation layer header, an RLC header, a medium access control (MAC) header, and a PHY header. The adaptation layer header may indicate one or more relays included in the route.

Abstract: Systems and methods of protecting an initial NAS message are described. The NAS message is encrypted using the home PLMN public key during initial registration with the network using a registration request message. An AMF of the serving PLMN sends a serving PLMN public key which is then used to encrypt information including an S-NSSAI of later initial NAS messages after initial registration is completed. The S-NSSAI may not be sent in the later initial NAS message if the S-NSSAI is provided at an access stratum level. The RRC message may contain an indication that the S-NSSAI is encrypted using the serving PLMN public key.

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: 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 SF 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: Beamforming measurement techniques based on PSS/SSS are disclosed. An apparatus of a user equipment (UE) can include processing circuitry configured to decode a configuration message from a source serving cell, the configuration message indicating signal selection criteria for cell measurement reporting. A synchronization signal (SS) burst set associated with one or more transmission/reception points (TRPs) within a neighboring cell is decoded, the SS burst set including a plurality of SS blocks. A cell beamforming measurement signal associated with the neighboring cell is generated, based on signal measurements of the SS blocks and the signal selection criteria. A radio resource management (RRM) measurement report message is encoded for transmission to the serving cell, the measurement report message including the cell beamforming measurement signal. A handover command message for initiating a handover to the neighboring cell is decoded, the handover command based on the cell beamforming measurement signal.
