Abstract: It is provided a method for determining packet loss in a fronthaul link between a baseband node and a radio node of a radio access network. The method being performed in a packet loss determiner. The method comprises: detecting at least one empty input data slot of a plurality of input data slots of a communication chain operation in a first time period, wherein the communication chain operation is one in a sequence of communication chain operations in a device on a receiving end of the fronthaul link; determining that data was intended to be provided to the at least one empty input data slot; and determining that a packet loss has occurred in the fronthaul link, based on the detecting the at least one empty input data slot and the determining that data was intended to be provided.

Abstract: Described is a method performed by an encoder of a base station system of a wireless communication network, for handling a data stream comprising a number of consecutive IQ samples for transmission over a transmission network between a remote unit and a base unit of the base station system. The remote unit is arranged to transmit wireless signals to and receive from mobile stations, each of the number of IQ samples comprising a first number of bits.

Abstract: Described is a method performed by an encoder of a base station system (100) of a wireless communication network, for handling a bit stream for transmission over a transmission link (165) between a remote unit (160) and a base unit (170) of the base station system. The remote unit is arranged to transmit wireless signals to and receive from mobile stations (180). The bit stream comprises a first OFDM symbol and a second OFDM symbol, each OFDM symbol comprising a number of consecutive IQ samples. The method comprises, for a first number of the IQ samples situated at a boundary between the first and the second OFDM symbol, transmitting, over the transmission link to a decoder of the base station system, the first number of IQ samples having a representation spanning a first amplitude range.

Abstract: Embodiments of the present invention relate to an arrangement for analyzing transmission line properties. Measurement data providing means provide data of a first frequency dependent line property, line property calculation arrangement with model handling means, a Hubert transform handler and line property determination means calculate said first property based on model parameters, line resistance at 0 frequency, roc, a cut-off frequency, v, a line capacitance C? and a line inductance L?H. The line model handling means calculates the line inductance L(f) via a Hubert transform of a function of Q(f/v), wherein the function Q(f/v) relates the line resistance R(f) to roc as R(f)=roc·Q(f/v). The Hilbert transform values are calculated using a parameterized closed form expression for the Hubert transform or they are tabulated.
