摘要： 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.

摘要： A first network node, a second network node and methods therein, for handling baseband processing of signals communicated with wireless devices in a wireless network. The first network node communicates a first type of signals with a first wireless device and performs a first part of baseband processing of the first type of signals using a non-GPP implemented processor. The first network node also communicates the first type of signals with the second network node for a second part of baseband processing of the first type of signals using a GPP implemented processor. The first network node further communicates a second type of signals with a second wireless device and performs both of said first and second parts of baseband processing of the second type of signals using the non-GPP implemented processor.

摘要： Embodiments presented herein relates to a method for saving power in remote radio heads (RRHs) of a wireless communication system. The method is performed in an RRH controller node associated with a plurality of RRHs or the same cell, each of the plurality of RRHs having at least a first antenna branch A of the cell and a second antenna branch B of the cell. The method comprises providing S120 a first power saving indication to a first RRH of the plurality of RRHs, to inactivate its first antenna branch A, and providing S120 a second power saving indication to a second RRH of the plurality of RRHs, to inactivate its second antenna branch B, wherein at least one antenna branch is kept active in the first and second RRH. RRH controller nodes, a computer programs and a computer program product for saving power in RRHs of a wireless communication system are also presented.

摘要： 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.

摘要： Disclosed is a method performed by a first unit of a base station system of a wireless communication network for handling a signal for transmission over a fronthaul link between the first unit and a second unit of the base station system. The base station system includes a base unit and a remote unit. The method includes receiving the signal having at least one complex value, each consisting of two subparts, each being represented by a first number of bits, and transmitting the signal over the fronthaul link to the second unit, wherein at least two subparts are represented in a subgroup, the subgroup being a binary codeword having an integer number of bits that is a multiple of a second non-integer number of bits allocated per subpart, the second non-integer number of bits being fewer than the first number of bits.

摘要： The present disclosure relates to methods and devices for communication systems comprising an electrically conductive line. The disclosure proposes a method in a line estimation device for determining termination characteristics of an electrically conductive line in a communication system. The method comprises outputting a test signal to the line, wherein the test signal is a wideband test signal with a bandwidth arranged to provide an adequate measurement time-resolution. The method further comprises receiving reflections from impedance discontinuities of the line in response to the test signal. The method also comprises forming a trace of the reflections. The method additionally comprises identifying at least one anomaly in the trace of reflections. The method yet further comprises determining termination characteristics of the line based on characteristics of the trace before and after the identified at least one anomaly. The disclosure also relates to corresponding line estimation devices and computer programs.

摘要： 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.
