Abstract: Techniques for random access (RA) in a cellular internet-of-things (CIOT) are discussed. An example apparatus configured to be employed within a User Equipment (UE), comprises a receiver circuitry, a processor, and transmitter circuitry. The receiver circuitry is configured to receive RA resource allocation information via one of a system information message or a downlink control information (DCI) message. The processor is operably coupled to the receiver circuitry and configured to: select a RA preamble sequence; generate a payload; and spread the payload via a spreading sequence. The transmitter circuitry is configured to transmit, based on the RA resource allocation information, a RA message comprising the RA preamble sequence and the payload, wherein the RA message is transmitted in a RA slot. The receiver circuitry is further configured to receive a response comprising a device identity of the UE and one of an uplink (UL) grant or a RA reject message.

Abstract: Embodiments described herein relate generally to a communication between a user equipment (“UE”) and a plurality of evolved Node Bs (“eNBs”). A UE may be adapted to operate in a dual connected mode on respective wireless cells provided by first and second eNBs. The UE may be adapted to estimate respective power headroom (“PHR”) values associated with simultaneous operation on the first and second wireless cells. The UE may cause the first and second PHR estimates to be transmitted to both the first and second eNBs. The first and second eNBs may use these estimates to compute respective uplink transmission powers for the UE. Other embodiments may be described and/or claimed.

Abstract: Methods, apparatus circuitry, and storage media are described for mobile-terminated packet transmissions. In one embodiment, an apparatus of a control plane device configured to operate within an evolved packet network core identifies a first service flow event trigger associated with a first packet data unit (PDU) session and processes a path reselection for a first PDU session in response to the first service flow event trigger, wherein the path reselection determines a new gateway for the first PDU session resulting from the path reselection. Transmission of a change notification to an application server controller associated with the first PDU session is initiated in response to the path reselection. Transmission of a routing update to the new gateway in response to the path reselection is also initiated. In various embodiments, the trigger may be a mobility event, a load balancing event, or operations in association with an application server controller.

Abstract: A 3GPP LTE protocol enhancement realizes the full benefit of discontinuous reception (DRX) in Long Term Evolution networks by coordinating and aligning DRX operations for conserving power and timing overhead. A dual connectivity enabled User Equipment (UE) comprising a processor and transceiver is configured to align DRX configuration between counterpart Evolved Node Bs (eNB)s, wherein counterpart eNBs are a Master eNB (MeNB) and a Secondary eNB (SeNB) simultaneously connected to the UE, communicate system frame timing and system frame number (SFN) information between the counterpart eNBs, align DRX start offset (drxStartOffset) values for the counterpart eNBs according to the communicated system frame timing and SFN information to compensate for offsets in system frame timing, and allow the start of a DRX ON duration at specific frame or sub-frame times determined by the drxStartOffset values, after the expiration of a DRX inactivity timer.

Abstract: An SDN architecture, for a cellular communications system, is described herein that includes a Quality of Service (QoS) provisioning framework to provision and manage traffic flows in the cellular communications system. The described architecture separates the control plane and the user plane for the transport of the user plane traffic. Network entities in the SDN architecture, such as a network controller, can detect and react to changes in network state (e.g., load conditions) to route or reroute traffic flows in the network. QoS and routing parameters may be determined for the network traffic on a per-flow basis, even when multiple flows are associated with a single service request.
