Abstract: Disclosed are methods, systems, apparatus, and computer programs for compressing an Ethernet packet. In one aspect, a method involves mapping a portion of the Ethernet packet to a connection identity to compress the Ethernet packet. Additionally, the method involves encoding, in a user plane protocol stack layer, the connection identity in a data structure for transmission.

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.

Abstract: The techniques, described herein, may enable a wireless telecommunication network to manage Mobility Management Entity (MME) overload scenarios by causing a Radio Access Network (RAN) node to temporarily bar certain User Equipment (UEs) from connecting to the RAN node. In some embodiments, UEs may be barred from connecting to the RAN node based on which UEs are operating in an enhanced coverage mode, Coverage Enhancement (CE) levels of each UE, and/or a measured Reference Signal Received Power (RSRP) of each UE.

Abstract: Methods, systems, and storage media are provided for user equipment (UE) that supports enhanced coverage and may operate with a voice centric usage setting or a data centric usage setting. When the UE's usage setting is set to voice centric, the UE may not operate in coverage enhancement (CE) mode B. When the UE's usage setting is set to data centric, then the UE may operate in CE mode B. The UE may indicate the UE's usage setting in an Attach or Tracking Area Update (TAU) request message, and a mobility management entity (MME) may indicate to an evolved NodeB that CE mode B is restricted or not restricted based on the usage setting. Other embodiments may be described and/or claimed.

Abstract: Support of Single-Cell Point-To-Multipoint (SC-PTM) for narrowband (UEs) and low complexity (BL) UEs can is implemented at both the physical layers and the higher layers. For example, in one implementation, a UE may transmit, to a Single-Cell Point-To-Multipoint (SC-PTM) base station, multicast service preference information, including at least one of a Coverage Enhancement (CE) mode or a maximum Transport Block Size (TBS) of the UE. The UE may also monitor a common search space (CSS) of a MTC Physical Downlink Control Channel (MPDCCH) or Narrowband Physical Data Control Channel (NPDCCH) for the scheduling of a Physical Downlink Shared Channel (PDSCH) or a Narrowband Physical Downlink Shared Channel (NPDSCH), respectively, to obtain downlink control information (DCI) that includes configuration information relating to a Single-Cell Multicast Control Channel (SC-MCCH).

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: 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: 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: 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.
