  • Patent number: 11057816
    Abstract: Notifying served user equipments (UEs) of the presence or absence of cell-specific reference signal (CRS) symbols transmitted by neighboring base stations in the physical downlink shared channel (PDSCH) region of a subframe can be achieved through various of signaling techniques. The served UE may be notified by communicating a one or multi-bit indicator in a physical layer signaling channel of the serving cell, such as the physical downlink control channel (PDCCH) of the subframe. Alternatively, the served UE may be notified through higher layer signaling.

    Abstract: Systems and methods for reducing false positive detections of malignant lesions are provided. A candidate malignant lesion is detected in one or more medical images, such as, e.g., multi-parametric magnetic resonance images. One or more patches associated with the candidate malignant lesion are extracted from the one or more medical images. The candidate malignant lesion is classified as being a true positive detection of a malignant lesion or a false positive detection of the malignant lesion based on the one or more extract patches using a trained machine learning network. The results of the classification are output.

  • Patent number: 10936947
    Abstract: At a network-accessible artificial intelligence service for time series predictions, a recurrent neural network model is trained using a plurality of time series of demand observations to generate demand forecasts for various items. A probabilistic demand forecast is generated for a target item using multiple executions of the trained model. Within the training set used for the model, the count of demand observations of the target item may differ from the count of demand observations of other items. A representation of the probabilistic demand forecast may be provided via a programmatic interface.

  • Publication number: 20210036755
    Abstract: The present disclosure relates to a method for reporting channel state information, a terminal, and a base station. A resource for an aperiodic channel state information reference signal (CSI-RS) is determined by the terminal according to an information for triggering an aperiodic channel state information (CSI) report sent by the base station, wherein the information for triggering the aperiodic CSI report indicates the resource for the aperiodic CSI-RS, and the aperiodic CSI report derived according to the aperiodic CSI-RS on the resource for the aperiodic CSI-RS is sent by the terminal to the base station. The base station transmits a CSI-RS only when the terminal needs to report the aperiodic CSI.

  • Patent number: 10840984
    Abstract: The present disclosure relates to a method for reporting channel state information, a user equipment, and a base station. A channel state information measurement resource is determined by a UE according to an aperiodic CSI trigger signaling, so that a base station transmits a CSI-RS only when the UE needs to report the aperiodic CSI. Compared with transmitting a periodic CSI-RS by an existing base station, unnecessary transmitting of the CSI-RS is reduced, and energy of the base station such as an eNB is saved; and reducing the CSI-RS transmission may reduce resources occupied by the CSI-RS, thereby improving the spectrum efficiency of the system. In addition, reducing unnecessary CSI-RS transmission allows the interference in other cells by the base station being reduced; finally, CSI measurement resources are reserved only when the CSI needs to be fed back, the cost occupied by the CSI measurement resources is reduced.

    Abstract: Gas separation unit for separation of a gas component from a process gas stream, said separation unit comprising a stator and a rotor comprising a plurality of sectors, each sector containing a separation device arranged to separate the gas component from the process gas stream which is led into the separation device and each sector being fluidically connected with at least one valve. The valve is a rotary active valve which comprises a rotor open area which is located at the rotor and a stator open area which is located at the stator. The rotor open area and the stator open area can overlap and can be laterally separated from each other by rotation of the rotor relative to the stator. In this way, the valve can at least partially be opened and closed. The extent of overlap of the rotor open area and the stator open area defines the extent of opening and closing of the valve, respectively. The extent of overlap corresponds to the extent of partial opening of the valve.
