  • Publication number: 20220345245
    Abstract: Embodiments of the present disclosure provide a solution for multi-TRP transmissions. In a method for communication, a terminal device receives from a network device coupled with a plurality of TRPs, control information associated with a transmission of data from the network device to the terminal device. The terminal device determines, from the control information, a repetition scheme to be used by the network device to transmit the data to the terminal device via the plurality of TRPs. The terminal device receives the data from the network device based on the repetition scheme. With the embodiments of the present disclosure, only one DCI can schedule repeated data for multi-TRP transmission without increasing the DCI payload relative to a Rel.15 DCI. Also, the repetition scheme for transmitting data can be indicated by a same DCI more dynamically.

  • Publication number: 20220322115
    Abstract: Inter-cell mobility across serving and non-serving cells based on layer 3 measurements is accomplished at the cost of increased delay. Inter-cell mobility across serving and non-serving cells based on layer 1 measurements minimized delay. A user equipment (UE) apparatus that is served by a serving cell of a base station receives, from the serving cell, a configuration to perform layer 1 (L1) measurements based on one or more reference signals from a non-serving cell. The UE also receives the one or more reference signals from the non-serving cell. The UE performs the L1 measurements on the one or more reference signals received from the non-serving cell based on the configuration received from the base station. The UE may perform the L1 measurements on a synchronization signal block (SSB), a channel state information reference signal (CSI-RS), or a positioning reference signal (PRS) from the non-serving cell.

The first segmentation scheme can be selected from: an equidistant segmentation scheme, a local extrema segmentation scheme, and a windowed segmentation scheme. The method further comprises associating a classification to the time series data based on the first segmentation scheme. The classification can be indicative of one selected from: stationarity of the time series data, periodicity of the time series data, and trending of the time series data.

  • Patent number: 11411186
    Abstract: A boron heterocyclic compound has a structure represented by Formula (I): in which L represents a single bond, a substituted or unsubstituted phenyl, a substituted or unsubstituted naphthyl, a substituted or unsubstituted anthryl, and D is mainly selected from carbazolyl and derivative groups thereof, acridinyl and derivative groups thereof, or diarylamino and derivative groups thereof. In the boron heterocyclic compound, an acceptor unit is bonded through a boron heterocyclic SP3 linking moiety, which shortens the conjugation length, increases the energy level, and also further improves the thermodynamic stability of the molecule. In addition, the short conjugate axis reduces intramolecular charge transfer and narrows luminescence spectrum to some extent. The compound can be used as a TADF material. Since the light-emitting layer of the light-emitting device does not contain noble metals, the cost thereof can be greatly reduced.

  • Publication number: 20220215173
    Abstract: An approach is provided for improving a named entity recognition. Using a multi-label classification in a neural network, a sub-entity is identified in an original sentence. First and second labels are determined indicating first and second candidate types of the sub-entity. First and second replacement sentences are generated. The first replacement sentence replaces the sub-entity in the original sentence with a first sub-entity of the first candidate type. The second replacement sentence replaces the sub-entity in the original sentence with a second sub-entity of the second candidate type. First and second confidence scores for the first and second replacement sentences are determined. Based on the first confidence score exceeding the second confidence score by more than a threshold amount, the neural network is retrained by selecting the first instead of the second candidate type as the sub-entity type.

  • Publication number: 20220180180
    Abstract: A data-driven model compression technique is introduced that only targets to provide same accuracy as the original (not compressed) model in certain areas by reducing compression parameters. A compression engine relies on backpropagation to determine an extent of parameter value changes and designate certain parameters as key parameters. The model matrix is reshaped according to importance of each neuron. Only randomly generated parameter values of the reshaped parameter matrix are fine tuned to create a reliable compressed neural network model.
