  • Patent number: 11362767
    Abstract: A receiver includes an antenna, a transceiver coupled to the antenna, a decoder and a processor. The transceiver receives from a transmitter of a wireless communication network a data block. The data block includes encoded data transmitted on a plurality of resources allocated to the receiver. The decoder decodes the encoded data and determines for the allocated resources whether decoding of the encoded data was successful or failed. The processor evaluates whether one or more of the resources for which the decoding failed are included in a report, the report indicating for one or more of the allocated resources that encoded data transmitted on the one or more allocated resources is not decodable or is likely to be not decodable, and causes the transceiver to send a retransmission request to the transmitter responsive to the evaluation.

  • Patent number: 11363268
    Abstract: Coding quantization parameter variation or adaptation is made more effective by basing the determination of a coding quantization parameter for a predetermined block of the picture on a dispersion of a statistical sample value distribution of a high-pass filtered version of the predetermined block. The usage of the high-pass filtered version of the predetermined block as a basis for the determination of the dispersion instead of using, for instance, the un-filtered or original version of the predetermined block assists in a better adaptation of the resulting coding quantization parameter variation across the picture to the human visual system. Alternatively or additionally, coding quantization parameter variation or adaptation across a picture is made more efficient by a control of coding quantization parameter variation/adaptation across a picture in a manner dependent on a prediction of the actual dispersion.

  • Patent number: 11363259
    Abstract: In accordance with a first aspect, an improved compression efficiency is achieved by letting a block-wise picture codec support a set of intra-prediction modes according to which the intra-prediction signal for a current block of a picture is determined by applying a set of neighboring samples of the current block onto a neural network. A second aspect of the present application is that, additionally or alternatively to the spending of neural network-based intra-prediction modes, the mode selection may be rendered more effective by the usage of a neural network dedicated to determine a rank or a probability value for each of the set of intra-prediction modes by applying a set of neighboring samples thereonto with the rank or probability value being used for the selection of one intra-prediction mode out of the plurality of intra-prediction modes including or coinciding with the set of intra-prediction modes.
