Abstract: A centralized RAN architecture that includes lower layer transmission nodes (referred to as distributed units (DUs) herein) that connect to an upper layer RAN node (referred to as a centralized unit (CU) herein). A centralized RAN architecture may include a functional split, between the CU and DU, corresponding to the Packet Data Convergence Protocol (PDCP) and Radio Link Control (RLC) layers. In one embodiment, a CU may store copies of downlink PDCP PDUs that are transmitted to a first DU.

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).

The UE can encode the eBSR for transmission to a next generation node B (gNB), wherein the eBSR includes information identifying the number of small packets pending for transmission. The UE can have a memory interface configured to send to a memory the number of small packets pending for transmission.

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: Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to determine that the UE is in an Inactive Radio Resource Control (RRC) state. The second circuitry may be operable to process a first transmission received by the UE while the UE is in the Inactive RRC state, the first transmission carrying a set of one or more Access Control (AC) parameters. The third circuitry may be operable to regulate the sending of a second transmission, in accordance with the set of one or more AC parameters, while the UE is in the Inactive RRC state.

Abstract: Techniques described herein may be used to enable User Equipment (UE) to switch between Radio Access Technologies (RATs) while transitioning from an inactive state to an active state. For example. a UE may connect to a base station via one type of RAT (e.g., Long-Term Evolution (LTE) RAT), enter an inactive state, and later, while transitioning from the inactive state to an active state, connect to another base station via another type of RAT (e.g., a New Radio (NR) or 5th Generation (5G) RAT). The UE may transition from one RAT to another RAT without increasing signaling between the UE and the network beyond minimal signaling involved in a transition of the UE from the inactive state to an active state. The network may further minimize signaling by determining and communicating minimized connection configuration information to the UE.

For example, an apparatus may include logic and circuitry configured to cause a User Equipment (UE) to determine a selected Common Control Channel (CCCH) message configuration from a first predefined message configuration and a second predefined message configuration, the first predefined message configuration having a first predefined message bit-size, the second predefined message configuration having a second predefined message bit-size; to generate an Uplink (UL) CCCH message according to the selected CCCH message configuration, the UL CCCH message comprising a Medium Access Control (MAC) header comprising a Logical Channel Identify (ID) (LCID) field having a value corresponding to the selected CCCH message configuration; and to transmit the UL CCCH message to a Next Generation Node B (gNB) over a logical channel corresponding to the selected CCCH message configuration.

Abstract: Coordination of RRC configurations between an LTE NB and an NR NB in dual connectivity with a UE are performed using an RRC container that includes shared or coordinated parameters. For example, an NR NB determines to alter a configuration of a UE. The NR NB transmits a coordinated RRC container with coordinated UE parameters to an LTE NB and transmits a UE parameter RRC container to the LTE NB. The LTE NB evaluates the coordinated container for compliance with the UE capability. If satisfied, the LTE NB can send both containers (in a single RRC message or multiple RRC messages) to the UE.
