    Abstract: Integrate access and backhaul (IAB) nodes can multiplex access and backhaul links in time, frequency, or space, which includes the transmission of signals and/or channels utilized as part of initial access and measurements used for radio resource management (RRM). The same physical layer signals and channels used for these purposes by access a user equipment device can be reused for performing similar procedures at the IAB node. Consequently, the IAB node can leverage various muting patterns to employ the use of half-duplex and full-duplex synchronization signal block radio resource management such that mobile terminal functionality and distributed unit functionality of the IAB node can receive and transmit signals simultaneously.

  • Patent number: 10901846
    Abstract: The techniques described herein are configured to improve the remanufacturing process by waiting to rebuild selective data items stored on a storage device that is unavailable. A storage device is unavailable when it is taken offline and/or disconnected from a network. The storage device may be taken offline due to a failed component (e.g., an actuator arm, an actuator head, damage to the underlying storage media, etc.). The storage device comprises multiple independent logical units, where a logical unit is a uniquely addressable portion of a storage device that is visible and/or that is exposed to a host. Accordingly, the techniques described herein are configured to conserve resources by selectively rebuilding data items stored in logical units of an offline storage device that are not affected by a remanufacturing process implemented due to a failed component.

  • Patent number: 10887146
    Abstract: Apparatuses, methods, and systems are disclosed for determining a location of a frequency-domain resource block using frequency spacing values. One apparatus includes a transceiver that communicates with a base station in a mobile communication network a processor that determines a first spacing value for frequency locations within a frequency range and determines a second spacing value for frequency locations within the frequency range. The processor receives (via the transceiver) information of a first scalar and a second scalar and determines a location of a set of frequency-domain resource blocks using a location of a reference resource block. Here, the location of the reference resource block is based on the sum of a product of the first scalar and the first spacing value and a product of the second scalar and the second spacing value. The apparatus receives data from the base station on the set of frequency-domain resource blocks.

    Abstract: A method and a system for improving efficiency of a bi-directional optical camera communication between a first OCC device and a second OCC device are disclosed. In an embodiment, the method may include estimating, by a first OCC device comprising a first display device and a first camera device, a first transmission parameter with respect to the first display device and a first reception parameter with respect to the first camera device. The first reception parameter is based on a second transmission parameter of a second OCC device or a channel condition parameter, and the second transmission parameter is derived from an analysis of information captured by the second OCC device from the first OCC device. The method may further include dynamically modifying, by the first OCC device, the first transmission parameter based on the first reception parameter in order to maximize throughput of OCC.
