Abstract: Some embodiments of this disclosure include apparatuses and methods for facilitating a transmission, retransmission, and hybrid automatic repeat request (HARQ) process using preconfigured uplink resources (PUR) in IDLE mode. In some embodiments, user equipment (UE) may establish a first PUR and a second PUR to use in IDLE mode. The UE may transmit uplink data using the first PUR using a HARQ process. The UE may start a PUR retransmission timer and monitor a control channel for an acknowledgement message. The UE may identify an expiration of the PUR retransmission timer prior to receiving the acknowledgement message, and in response, may retransmit the uplink data using the second PUR.

Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for operating eMTC (enhanced Machine Type Communication) user equipment (UE) and/or NB-IoT UEs when connected to a 5G Core Network (5GCN). For example, some embodiments are directed to a user equipment (UE). The UE includes processor circuitry and radio front circuitry. The processor circuitry can be configured to receive, using the radio front end circuitry and from a Non-Access Stratum layer (NAS) of a cell, an indication to use a 5G Core Network (5GCN) for the cell. The processor circuitry can be further configured to transmit, using the radio front end, a Radio Resource Control (RRC) connection request in response to the indication to use the 5GCN.

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.
