  • Patent number: 10667301
    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.

  • Patent number: 10631359
    Abstract: Technology for a mobile station (MS) configured for cellular Internet of Things (CIoT) is disclosed. The MS can receive a ready state discontinuous reception (RS-DRX) configuration message from a base station, wherein the RS-DRX configuration message includes one or more RS-DRX parameters. The MS can initiate RS-DRX based on the one or more RS-DRX parameters included in the RS-DRX configuration message. The RS-DRX can enable the MS to be in a packet idle state of a ready state in between data communications by the MS with the base station. The MS can be configured to periodically switch from a defined sleep duration to a defined ON duration during the packet idle state of the ready state and check for downlink or uplink packet arrivals.

  • Patent number: 10624152
    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.

  • Publication number: 20200107278
    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.

  • Patent number: 10581549
    Abstract: A base station can obtain channel quality conditions for mobile devices in a scheduling interval and identify a channel quality, a target transmission scheme, and a transmission power level for each of the mobile devices. The base station can assign a unique orthogonal CDMA code and can force the mobile devices to transmit K repeated bursts of uplink data such that each of the mobile devices has a rotated phase shift based on the unique orthogonal CDMA code assigned to each of the mobile devices with each of the mobile devices multiplexed on a same physical channel using an overlaid CDMA operation. The base station can process K repeated bursts that are multiplexed on the same physical channel using the overlaid CDMA operation. The base station can separate the mobile devices according to the unique orthogonal CDMA code and use IQ accumulation according to combine the K repeated bursts.

  • Patent number: 10492142
    Abstract: Described herein are various wake-up procedures for user equipments (UEs). A UE may include a low power wake-up radio (LP-WUR) separate from a front end module (FEM). The LP-WUR may remain awake continuously (or at high-frequency intervals) and monitor for a wakeup signal, allowing the FEM to remain powered down in the absence of downlink data. When the LP-WUR detects a wakeup signal configured for the LP-WUR, the LP-WUR may be configured to wake up the FEM to receive incoming downlink data. Various network components may be configured to ensure UEs with LP-WURs receive corresponding wake-up signals.

  • Publication number: 20190327134
    Abstract: Systems and techniques for mission critical (MC) push notification mechanism in a high-reliability (HR) information centric network (ICN) are described herein. For example, a node may test network links to other nodes to classify the other nodes into proximate nodes and non-proximate nodes based on a reception metric. The node may then elect a set of leader nodes from the proximate nodes. Here, the set of leader nodes are selected based on link quality between respective leader nodes and non-proximate nodes. The node may detect an MC event and create an ICN data packet that contains data from the MC event. The node may then transmit the ICN data packet to the set of leader nodes that then relay the ICN data packet to the non-proximate nodes.

  • Patent number: 10334642
    Abstract: Devices and methods of using a reduced complexity network protocol are generally described. An evolved NodeB (eNB) transmits an Attach Request to a mobility management entity (MME), which transmits a Create Session Request for transmission of non-IP (NIP) data of user equipment (UE) to a Packet Data Network (P-GW). The P-GW in response transmits a Create Session Response, with the UE ID if originating at the P-GW and free from a UE IP address and an Up Link Traffic Flow Template, to the MME, which transmits an Attach Accept to the eNB and UE. A UE identifier (UE ID) either originates at the UE and is transmitted in the Attach Request, or is generated by the eNB, MME or P-GW. The NIP data has a tunneling NIP data packet with a NIP header with the UE ID and a NIP user data packet free from TCP/IP encapsulation and header compression.
