  • Patent number: 10743371
    Abstract: Embodiments of an Evolved Node-B (eNB), a MulteFire narrowband internet-of-things User Equipment (MF NB-IoT UE), and methods of communication are described herein. The eNB may transmit an unlicensed narrowband primary synchronization signal (U-NPSS) in a plurality of subframes. The eNB may, for the U-NPSS, for each subframe of the plurality of subframes, and for each of the orthogonal frequency division multiplexing (OFDM) symbols of the subframe: repeat a sequence of length-11; and map the sequence to 11 resource elements (REs) of a physical resource block (PRB) of 12 REs. The eNB may process the U-NPSS by an orthogonal cover code (OCC) over the plurality of subframes. The sequence in each of the OFDM symbols of each of the subframes of the plurality of subframes may be multiplied by a different element of the OCC.

  • Publication number: 20200169955
    Abstract: Machines or networked devices such as internet of things (IoT) devices operate to generate an unlicensed IoT (U-IoT) communication or enhanced Machine Type Communication (eMTC) based on frequency hopping operations on different channels. An anchor channel can be configured to carry system information and paging messages for the U-IoT/eMTC communication on the different channels. The system information and paging messages can include essential system information such as a system information block MulteFire (SIB-MF) message. Physical channels can be configured to enable component carriers anchored to a long term evolution (LTE) licensed band, and entirely comprise unlicensed carrier components that are unanchored to any LTE component carrier in a standalone configuration to enable transmission of the U-IoT communication in standalone communications in an unlicensed band.

  • Publication number: 20200092858
    Abstract: Systems and methods of early termination of uplink data transmissions for a UE are described. The UE transmits capacity information that indicates that the UE supports use of an ETS. The ETS indicates successful reception by the eNB of the uplink data prior to an end of a scheduled transmission period to transmit repeated instances of the data. The UE receives a schedule for repeated transmissions of the data that is based on a coverage level of the UE, and then transmits sets of one or more repetitions. After the transmission, the UE monitors a predetermined resource whether the ETS is present or whether the ETS indicates an ACK. If the ETS indicates successful reception, the UE terminates transmission of the remaining repetitions of the data and enters a sleep mode or transmits other uplink data.
