    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: 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: 10530558
    Abstract: Embodiments of an intra-QCI scheduler and method for assisted intra-QCI scheduling are generally described herein for operating within a wireless access network in which data flows are mapped to bearers using quality-of-service (QoS) class identifiers (QCIs). In some embodiments, the intra-QCI scheduler may classify packets of one or more data flows having a same QCI with a sub-QCI based on intra-QCI classification information received from user equipment (UE). The sub-QCI may indicate a scheduling priority for packets of data flows having the same QCI. The intra-QCI scheduler may schedule packets for downlink transmission over a radio bearer between the eNodeB and the UE based on the sub-QCI. The use of sub-QCIs allows the eNodeB to provide QoS support for data flows of applications that have been mapped to a default bearer.

  • Publication number: 20190297674
    Abstract: Embodiments of an access point (AP), station (STA), and method of communication are generally described herein. The AP may perform channel sensing in a first channel of a first frequency band and a second channel of a second frequency band to obtain access for transmission of a physical layer convergence procedure (PLCP) protocol data unit (PPDU) that comprises multiple subframes. The transmission of the PPDU may be configurable to use a multi-band layer-1 aggregation of the first and second channels. While the second channel is unavailable, the AP may transmit one or more subframes on the first channel without usage of the multi-band layer-1 aggregation. When it is determined that the second channel has become available, the AP may switch to synchronized transmission of the subframes on the first and second channels in accordance with the multi-band layer-1 aggregation.
