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: 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).

Abstract: Embodiments herein provide a transfer framework and procedure for a failure indication and subsequent recover message for a user equipment (UE) in multi-radio access technology (MR)-dual connectivity (DC). For example, in embodiments, a UE may send an indication of a radio link failure (RLF) on a master node (MN) to a secondary node (SN) via a signalling radio bearer type 3 (SRB3). The SN may forward the indication to the MN (e.g., in a transparent manner). In some embodiments, the indication may be formatted in the same format as messages on signalling radio bearer type 1 (SRB1). Other embodiments may be described and claimed.

Other embodiments may be described and/or claimed.

Abstract: Technology to support access-class-barring (ACB) skipping for commercial and public-safety user equipments (UEs) is disclosed. A cellular mobile network experiencing congestion at the core network level can be configured to send a communication to UEs indicating that ACB may be skipped by UEs seeking to establish device-to-device (D2D) communication using a first mode of D2D resource allocation wherein D2D resources are allocated by the network. In addition, the network can be configured to send a communication indicating that a second mode of D2D resource allocation wherein D2D resources are allocated by the UEs may be used as an alternative to the first mode. The network may also indicate that the second mode can be used as a fallback when current ACB parameters indicate that use of the first mode is not currently permitted.

Uplink HARQ may include, for example, for a first synchronous HARQ process, a UE selects first downlink resources to monitor for first HARQ feedback based on the first HARQ RTT value, and generates a first HARQ retransmission for first uplink resources in response to the first HARQ feedback. For a second synchronous HARQ process, the UE select second downlink resources to monitor for second HARQ feedback based on the second HARQ RTT value, and generates a second HARQ retransmission for second uplink resources in response to the second HARQ feedback. In certain embodiments, a RAN node signals or indicates the variable RTT values to the UE.

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.

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: Technology described herein relates to systems, methods, and computer readable media to implement extended Discontinuous Reception (eDRX) for user equipments (UEs). A Mobility Management Entity (MME) can be aware of the starting time and length of an eDRX cycle of a UE so that the MME can send a paging message for the UE to an evolved Node B (eNB) shortly ahead of a Paging Occasion (PO). In some examples, more than one PO can be included within an eDRX cycle. An eDRX timer can be used to control the duration of waking times and, if desired, to maintain legacy compatibility. Additional examples provide a way for the MME to update calculations regarding the starting time and length of eDRX cycle of the UE such that the MME will continue to be apprised of when the UE will be reachable when the UE moves between cells.

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.
