Abstract: Aspects of this disclosure are directed towards an apparatus including one or more processors coupled to a memory. The one or more processors are configured to perform a paging reception, when in a camped on any cell state, by processing only a physical downlink control channel (PDCCH). Or perform the paging reception, when in a camped normally state, by processing a first reception of the PDCCH, and processing a second reception of a physical downlink shared channel (PDSCH). The one or more processors are further configured to receive a communication, according to the paging reception.

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: Systems, methods, and devices are provided to: perform packet data convergence protocol (PDCP) deciphering of the packets to store deciphered packets in a common buffer; perform PDCP reordering of the deciphered packets in the common buffer to generated a stream or reordered packets; perform robust header compression (ROHC) decompression on the stream of reordered packets; and determine, based on a packet indication, to reset the ROHC decompression, wherein the packet indication comprises a single bit in a PDCP header set to indicate a start of ROHC reset based on a path switch during a handover from a source cell to a target cell.

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: 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: User equipment (UEs) can fallback to a legacy system, such as an evolved packet system (EPS), from a fifth generation system (5GS). For example, a UE camps on the 5GS network by default. When an indicator of a voice call is detected, the UE performs a fallback to EPS for a duration of the voice call. After the voice call, the UE can return to the 5GS. In another example, the UE detects an emergency session request (e.g., internet protocol multimedia subsystem (IMS) emergency session request). The UE performs a fallback to EPS for a duration of the emergency session. After the emergency session is complete, the UE can return to the 5GS. The solution can operate with UEs that operate in either Single Registration (SR) mode embodiments or Dual Registration (DR) mode embodiments. Depending on the embodiment, the UE can perform a handover or redirection to the legacy system (such as E-UTRAN).

Abstract: Disclosed are apparatuses for quality of service (QoS) flow to data radio bearer (DRB) mapping override bits. An apparatus of a user equipment (UE), includes one or more data storage devices, and one or more processors operably coupled to the one or more data storage devices. The one or more data storage devices are configured to store data corresponding to mapping of QoS flows to data radio bearers. The one or more processors are configured to map one or more QoS flows to a DRB in an uplink (UL) responsive to receipt, by the UE from a cellular base station, of a user plane packet in a downlink (DL) through the DRB if an override bit of the user plane packet indicates that reflective mapping should apply.

Abstract: Systems and methods provide flow control for uplink traffic in an integrated access and backhaul network. A first relay node determines that its uplink buffer has reached an occupancy level higher than a pre-determined level. In response, the first relay node transmits, to a second relay node associated with the first relay node, a message indicating a buffer occupancy status of the uplink buffer of the first relay node.
