Abstract: A device of a User Equipment (UE), a method to operate the device, and a machine readable medium. The device includes processing circuitry and a radio frequency (RF) interface coupled to the processing circuitry, the processing circuitry to: decode a signal sent in a cellular network from a base station (BS), the signal including a network allocation vector (NAV) information update regarding a NAV corresponding to a Wi-Fi network, the NAV to be set by a Wi-Fi station (STA) that is in the Wi-Fi network, and that is to be coupled to the UE via a connection; and send the NAV information update to the STA by way of the connection to allow the STA to set its NAV in the Wi-Fi network based on the NAV information update.

Abstract: Embodiments described herein relate to managing bearers in a radio access network (e.g., next generation RAN (NG-RAN), etc.). In one example, a central-unit control-plane (CU-CP) communicates with a distributed unit (DU) and a CU-UP to exchange transport network layer addresses (TNLAs) and tunnel endpoint identifiers (TEIDs) between the DU and the CU-UP. In this way, the DU becomes resistant to the CU-UP's rejection of a bearer setup request from the CU-CP during a bearer setup procedure. Furthermore, during virtual machine (VM) migration or local problems of the CU-UP, an E1 procedure known as “bearer relocate” can be defined to notify the DU of a new TNLA for one or more affected general packet radio service tunneling protocol (GTP) tunnels that are affected by the VM migration or local problems.

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 modifying the bearer context of a DRB of an E1 interface for a gNB are described. To modify the bearer context associated with a DRB for a particular UE, the gNB-CU-UP transmits a Bearer Context Modification Required message through the E1 interface and receives in response a Bearer Context Modification Confirm message that confirms the modification of the bearer context. The Bearer Context Modification Required message and Bearer Context Modification Confirm message both include the new GTP TEID and TNL address to be used after modification of the bearer context, a gNB-CU-CP UE E1AP ID that uniquely identifies a UE association over the E1 interface within the gNB-CU-CP, a gNB-CU-UP UE E1AP ID that uniquely identifies a UE association over the E1 interface within the gNB-CU-UP, and a DRB ID IE that uniquely identifies the DRB.

Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configurable to operate as a source gNB (S-gNB). The S-gNB may transfer, from a control plane (CU-CP) of the S-gNB to a CU-CP of a target gNB (T-gNB), an XnAP handover request message that indicates an Xn handover of a User Equipment (UE) from the S-gNB to the T-gNB. The S-gNB may initiate data forwarding, from a user plane (CU-UP) of the S-gNB to a CU-UP of the T-gNB, of downlink data packets. The data forwarding may be terminated based on reception of end marker packets from a user plane function (UPF) entity. The CU-UP of the S-gNB may transfer end marker packets to the CU-UP of the S-gNB to indicate termination of the data forwarding.

Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with a gNB-CU and a gNB-DU. A first paging message for paging of the UE may be received at the gNB-CU from an access management function (AMF) entity. The first paging message may include: a paging identity of the UE; and a paging origin information element (IE) that indicates whether the paging of the UE is originated due to a protocol data unit (PDU) session from non-3GPP access. A second paging message to page the UE may be transmitted from the gNB-DU to the UE. The second paging message may include: the paging identity of the UE; and an access type parameter that indicates whether the paging of the UE is originated due to the PDU session from the non-3GPP access.

Abstract: Some demonstrative embodiments include devices, systems and methods of offloading traffic of a Secondary Cell Group (SCG). For example, some embodiments may include identifying a SCG bearer that is offloadable to the Internet via a Network Address Translation (NAT) gateway, based on offloading information received from a Master Evolved Node B (eNB) (MeNB); and offloading uplink Internet Protocol (IP) packets of the SCG bearer to the Internet via the NAT gateway, if the SCG bearer is indicated to be offloadable.
