Abstract: Embodiments of a User Equipment (UE), Evolved Node-B (eNB) and methods for communication in accordance with a packet convergence and link control (PCLC) layer are generally described herein. The UE may receive, from a Fifth Generation (5G) eNB, a first group of medium access control (MAC) protocol data units (PDUs) that include PCLC PDUs. In accordance with PCLC sequence numbers (SNs), the UE may reorder the PCLC PDUs and may decipher the PCLC PDUs. The UE may receive, from a legacy eNB, a second group of MAC PDUs that include packet data convergence protocol (PDCP) PDUs encapsulated in radio link control (RLC) PDUs. The UE may reorder the RLC PDUs based on RLC SNs and may decipher the RLC PDUs based on PDCP SNs that are exclusive to the RLC SNs.

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 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.
