摘要： 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.

摘要： 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.

摘要： An architecture, for a cellular communications system, is described herein in which a “bearer-less” model is used for both the radio interface and the network core. Instead of using an individual Layer 2 bearer for each Quality of Service (QoS) class, in the architecture described herein, a common Layer 2 connection (e.g., a Layer 2 “fat pipe”) may be used to handle traffic flows between a User Equipment (UE) device and an external Packet Data Network (PDN). Additionally, a bearer-less architecture may be used in the radio interface (i.e., between User Equipment (UE) and the eNB).

摘要： Technology for user equipment (UE) and evolved NobeB (eNB) to support enhanced coverage is disclosed. If both the UE and eNodeB provide support for a first and second coverage enhancement (CE) mode, one or more timers of the UE, eNB and a core network (CN) can 5 be configured according to an extended timer range. However, if either the UE or the eNB does not provide support for both the first and second CE modes, the one or more timers of the UE, eNB and CN are configured according to a legacy timer range.

摘要： 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.

摘要： 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.

摘要： Embodiments described herein relate generally to techniques for paging in a wireless network. In some embodiments, a mobility management entity (MME) may determine a user equipment (UE) is associated with a predetermined category and adjust paging mechanisms based on said determination. Other embodiments may be described and claimed.

摘要： A user equipment (UE) operable to perform inter-frequency measurements is disclosed. The UE can decode an information element (IE) received from an eNodeB. The UE can determine whether the IE received from the eNodeB includes a reduced measurement performance field. The UE can determine that a neighboring inter-frequency is configured for a reduced measurement performance when the reduced measurement performance field is included in the IE.

摘要： 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.
