  • Publication number: 20240340661
    Abstract: Embodiments herein may for example disclose a method performed by a transmitting node, such as a first network node, for handling communication between a control node and a device controlled by the control node. The control node and the device are configured for wired communication. The transmitting node receives one or more packets in a first format from the control node or the device over a wired connection. The transmitting node processes the one or more packets into a second format for communication over a wireless connection by using a transmission process for processing the one or more packets into the second format; and transmits the one or more packets in the second format over the wireless connection towards the device or the control node.

  • Patent number: 11632139
    Abstract: In mobile communications networks, requirements on signal distortion may be fulfilled at a lower bit rate, or alternatively quantization noise be reduced for a given bit rate, by including fractional exponent bits in a block floating point format. One or more fractional exponent bits may apply to all samples in the block. Alternatively, fractional bits may apply to sub-blocks within the block. The optimal number of fractional bits depends on the number of samples in the block.

  • Patent number: 11411606
    Abstract: Disclosed is a technique for estimating crosstalk between a first and second electrical transmission lines. The method comprises obtaining measurements of a received near end crosstalk, NEXT, signal, the NEXT signal being received at a first end of the second transmission line over a time period as a result of an electrical signal sent onto the first transmission line from its first end, the obtained measurements being in the time domain. Subsequently, a crosstalk coupling estimate is obtained per transmission line sub-interval by compensating the obtained measurements in the time domain of the received NEXT signal for round-trip attenuation of the sent signal from the first end of the first line to the sub-interval and back to the first end of the second line, and an estimate of a total crosstalk coupling is obtained by adding together at least some of the obtained crosstalk coupling estimates per transmission line sub-interval.

  • Patent number: 11329668
    Abstract: A method performed by an encoder of a base station system, for handling a data stream for transmission over a transmission connection between a remote unit and a base unit of the base station system, the remote unit being arranged to transmit wireless signals to, and receive from, mobile stations. The method comprises quantizing a plurality of IQ samples, converting the quantized plurality of IQ samples to IQ predictions, calculating per sample a difference between the quantized plurality of IQ samples and the IQ predictions in order to create IQ prediction errors. The method further comprises quantizing the IQ predictions or the IQ prediction errors, entropy encoding the IQ prediction errors and sending the entropy encoded IQ prediction errors over the transmission connection to a decoder of the base station system. The method can be performed by a decoder.
