Abstract

A frequency-domain audio codec is provided with the ability to additionally support a certain transform length in a backward-compatible manner, by the following: the frequency-domain coefficients of a respective frame are transmitted in an interleaved manner irrespective of the signalization signaling for the frames as to which transform length actually applies, and additionally the frequency-domain coefficient extraction and the scale factor extraction operate independent from the signalization. By this measure, old-fashioned frequency-domain audio coders/decoders, insensitive for the signalization, would be able to nevertheless operate without faults and with reproducing a reasonable quality. Concurrently, frequency-domain audio coders/decoders able to support the additional transform length would offer even better quality despite the backward compatibility. As far as coding efficiency penalties due to the coding of the frequency domain coefficients in a manner transparent for older decoders are concerned, same are of comparatively minor nature due to the interleaving.

One main polarization axis is assigned with each of the core regions. The stress elements may be distributed in groups of two or more stress elements across the cross-section of the optical fiber. In a cross-sectional view, the stress elements have an asymmetrical, namely non-rotationally symmetrical arrangement, which causes the main polarization axes to point in the same direction in all core regions.

Abstract

A picture in a data stream is subdivided into different size transform bocks. For a transform block, a transformation is selected by checking whether the block's size exceeds a threshold. If it does, a default technique is used to select the transformation. If it does not, a transformation is used from a list of transformations as identified by an index, the list including an identity transformation and non-identity transformations. A coefficients block in the data stream is decoded, and if the selected transformation is the identity transformation, then the coefficients block is used as a residual sample array, and if the selected transformation is not the identity transformation, the coefficients block is subjected to an inverse transformation corresponding to the selected transformation to obtain a residual sample array used to correct a prediction for the transform block.

According to the present invention, multiple parametrically encoded audio signals can be efficiently combined using an audio signal generator, which generates an audio output signal by combining the down-mix channels and the associated parameters of the audio signals directly within the parameter domain, i.e. without reconstructing or decoding the individual input audio signals prior to the generation of the audio output signal.

Abstract

The invention describes an encoding scheme for encoding a sequence of integer values, particularly by first using encoding a value at a predetermined position and then consecutively calculating and encoding differences between neighboring values. A respective decoding scheme is also provided. These encoding and decoding schemes provide a more efficient encoding concept.

Abstract

An embodiment provides a server UE, especially UE acting as positioning session coordinator, having a transceiver and a controller, wherein the transceiver is configured to receive positioning request (from its higher layers or from a second entity), wherein the controller is configured to initiate and/or maintain a positioning session for a target UE, wherein the positioning session has at least a measurement between the target UE and an anchor UE; to select out of a plurality of UEs at least one anchor UE fulfilling one or more anchor UE selection criteria; and to coordinate assignment of the configuration associated with at least one resource for transmission and/or for reception with the target UE and the anchor UE involved in the positioning session.

Abstract

A user device, UE, for a wireless communication network is described. The UE is a sidelink, SL, UE, and is to communicate with one or more further SL-UEs over a sidelink, SL, using more than one antenna or antenna element. The UE is served by a base station of the wireless communication network. The UE is to be assisted by the base station for one or more beam management procedures.

Abstract

For neural network representation determination, forward-passes are cyclically performed using a quantized version of weights of a neural network or using the weights of a neural network, and a weights-to-bitrate or weights-to-bitlength function is determined by determining, for each of a plurality of entropy coding contexts, a probability estimate depending on statistics of binary strings obtained from quantization indices of quantization levels of the weights or the quantization indices, and a discrete function mapping the quantization levels or the quantization indices onto bitrates by determining bit lengths for binary strings which comprise one or more context-adaptive entropy coded bins using a bin-wise summation over a logarithmized version of the probability estimate of the entropy coding context. The weights-to-bitrate or weights-to-bitlength function is formed by a summation of, for each of the weights, an approximation function approximating the discrete function and a combined loss function based on a performance loss function of the forward-passes and the weights-to-bitrate or weights-to-bitlength function. Finally, for each weight, a gradient of the combined loss function is determined and used to update the respective weight for a next cycle.
