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: Devices, methods, user equipment (UE), network core devices, gateway devices, evolved node B (eNB), and storage media for UE provisioning are described. In one embodiment, a UE is configured for codec bitrate adaptation via an interface configured to receive a bandwidth indication and a codec awareness indication from an eNB. The UE process the bandwidth indication and identifies, based on the codec awareness indication, a first codec from a plurality of codecs supported by the UE. The UE then configures with the eNB using data encoded with the first codec. This data may, for example, be Voice over Long-Term Evolution (VoLTE) data or other such media data. Selection of the codec or associated codec information may be further based on the codec awareness indication.

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.

Abstract: A UE in idle mode may use a preconfigured uplink resource for transmission, retransmission, and/or HARQ. For example, the UE may store configuration data for a preconfigured uplink resource and an RNTI for idle mode communication. In idle mode, the UE generates an uplink transmission using the preconfigured uplink resource. After the uplink transmission, the UE starts a retransmission timer, and monitors PDCCH with the RNTI provided in the configuration data for HARQ ACK/NACK.

Abstract: A user equipment (UE) can include processing circuitry configured to decode system information including access barring parameters for one or more access categories for accessing a cell of a next generation Node-B (gNB). A network access attempt is detected by a control plane layer of the UE that is higher than a Radio Resource Control (RRC) layer. The processing circuitry map s, using a Non-Access Stratum (NAS) layer of the control plane, the network access attempt to at least one access category of a plurality of available access categories based on mapping rules. The processing circuitry performs an access barring check procedure for the mapped at least one access category based on the access barring parameters. Upon determining that access to the cell is not barred, a NAS message is encoded for transmission to an Access and Mobility Management Function (AMF), e.g. an Attach Request message to perform an attach procedure.

Abstract: Techniques described herein allow for mobile positioning (i.e., the determination of the position of the UE) to be performed when the UE is in Idle mode. In some implementations, assistance data, that is used by the UE as part of the mobile positioning procedure, may be broadcast to the UE or transmitted to the UE within paging messages. The assistance data can potentially be sent to the UE in a number of time slots. In some implementations, the UE may perform measurements needed for mobile positioning only within discontinuous reception (DRX) occasions. Alternatively, in some implementations, the UE may perform measurements needed for mobile positioning outside of DRX occasions.

Abstract: System and methods of providing location techniques for a NB UE are described. The UE transmits, to a location server, a capability message that indicates position capabilities of the UE to support different positioning methods and common information related to the position methods, including that the UE is a NB UE. The UE receives a request for location information that includes a request for positioning measurement for a particular positioning method, a NB message size limit that indicates a limit on an amount of location information to return, and a NB response time to provide the positioning measurements. At least one of the response time or message size limit is different than for the NB UE than for non-NB UEs. The UE enters an idle state, performs the measurements, and transmits at expiry of or before the NB response time, a message containing the measurements.

Abstract: 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.

Abstract: Methods, systems, apparatus, and computer programs, for selecting radio link control (RLC) entities to transmit packet data convergence protocol (PDCP) control protocol data unit (PDU). In one aspect, the method includes actions of accessing, by a device in a wireless communication system, data representing an index of RLC entities of a data radio bearer (DRB)/PDCP entity and RLC activation state information, the activation state information indicating whether one or more RLC entities of the DRB/PDCP entity in the index of RLC entities is activated or deactivated, selecting, by the device in the wireless communication system, a subset of the RLC entities of the DRB/PDCP entity based on an index position in the index and the activation state information for each of the RLC entities, and using the selected subset of RLC entities of the DRB/PDCP entity to transmit the PDCP Control PDU.
