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: Systems 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 measurements 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: A process for execution by user equipment (UE) for activation or deactivation of a Radio Link Control (RLC) entity for Packet Data Convergence Protocol (PDCP) duplication includes identifying a set of RLC entities that are configured by a Radio Resource Control (RRC) for communication using PDCP. The process includes, for each RLC entity of the set of RLC entities: determining a network configured offset value; determining a channel condition value; and determining an RLC entity level value based on a combination of the network configured offset value and the channel condition value. The process includes comparing the RLC entity level value for each RLC entity to a threshold value; and based on comparing the RLC entity level value to the threshold value, selecting a subset of RLC entities for PDCP duplication; and activating or deactivating PDCP duplication for the selected subset of RLC entities.

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: An apparatus of a user equipment (UE) includes processing circuitry configured to decode a master information block (MIB) using a set of physical broadcast channel (PBCH) symbols received within a downlink frame to obtain system frame number (SFN) information. The downlink frame includes multiple copies of the PBCH symbols within at least three subframes of the downlink frame. A system information block (SIB) may be decoded based on the SFN information, to obtain uplink channel configuration information. Random access channel (RACH) procedure may be performed with a base station (BS) based on the uplink channel configuration information, to obtain an uplink resource assignment. A connection setup completion message can be encoded for transmission to the BS using the uplink resource assignment. The set of PBCH symbols can include a set of four legacy PBCH symbols.

Abstract: This disclosure relates to implementations to support non-UE-specific (i.e. common) and UE-specific search spaces (SS) for M-PDCCH. One implementation relates to a UE comprising RF circuitry to receive, from an eNB, configuration information of one or a plurality of common Search Spaces (CSSs) for M-PDCCH; and baseband circuitry to monitor the one or more configured CSS for M-PDCCH transmissions; wherein the RF circuitry and/or baseband circuitry is adapted to support a reduced bandwidth (BW). Another implementation relates to an eNB comprising RF circuitry to transmit configuration information of a plurality of CSSs for M-PDCCH to one or more UEs supporting a reduced BW, wherein the plurality of CSSs for M-PDCCH are differentiated by “based on functionality”-differentiation that includes the type of use case and/or an EC level of the UE.
