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: 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: 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: An apparatus is configured to be employed within a base station. The apparatus comprises baseband circuitry which includes a radio frequency (RF) interface and one or more processors. The one or more processors are configured determine repetition level (RL) thresholds, allocate downlink resources, wherein the downlink resources include a repetition level (RL), send downlink data to the RF interface for transmission to a user equipment (UE) according to the RL, receive repetition feedback from the RF interface based on the transmission to the UE, and update aspects or the allocation of the downlink resources based on the repetition feedback.

Abstract: Adaptive paging techniques for EC-capable devices are described. In one embodiment, for example, an apparatus may comprise at least one memory and logic for an evolved node B (eNB), at least a portion of the logic comprised in hardware coupled to the at least one memory, the logic to receive an S1 paging message comprising a user equipment (UE) identifier (ID) associated with a UE and an extended coverage (EC) capability indicator indicating that the UE is EC-capable and page the UE using an EC paging sequence based on receipt of the S1 paging message, the EC paging sequence to comprise a series of transmissions of a radio resource control (RRC) paging message, the logic to truncate the EC paging sequence based on a determination that the UE has responded to RRC paging. Other embodiments are described and claimed.

Abstract: 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.

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.
