  • Patent number: 10999380
    Abstract: Methods and procedures allow devices interwork with various types of service layers by updating the device to support the protocol of the M2M/IoT service layer that is being communicated with. Devices can coordinate/initiate download of a service layer API that is compatible with the service layer the device is attempting to use. A service layer can coordinate the autonomous update of a device with the proper service layer API which allows the device to then communicate and use services supported by the service layer component to the device. A service layer can detect a device or application lacking proper service layer functionality and can trigger a management entity to update the device or application with the service layer API required such that the device can then register to the service layer and use its services. A device or application can be customized or optimized to the service layer that it is registered to and using.

  • Publication number: 20210126749
    Abstract: Flexibly configured containers consisting of resources within time-frequency blocks may be used to support multiple numerologies in new radio architectures. Uplink control may be defined in resources within a container, or in dedicated resources, by various nodes. Sounding reference signal resources may be dynamically configured for each numerology. The sequence length may be adapted, as well as the time domain location of symbols. Time, frequency, and orthogonal resources may be allocated via a downlink control channel or a radio resource control. Sounding reference signals may be pre-coded, and pre-coding weights may be based on a codebook or non-codebook approaches, e.g., via a radio resource control or a downlink RRC or DL control channel. Pre-coded sounding reference signals may be adapted to user equipment antenna configuration. Further, NR-SRS may be used as UL demodulation RS (DM-RS).
