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. The method comprises quantizing, by a quantizer, the IQ samples or IQ prediction errors of the IQ samples with a second number of bits, wherein an amplitude range of the quantizer for the second number of bits is variable and set based on an acceptable signal quality value, entropy encoding the quantized IQ samples or IQ prediction errors applying a first entropy encoding dictionary out of a plurality of entropy encoding dictionaries, based on the set amplitude range of the quantizer, and transmitting, to a decoder, the entropy encoded and quantized IQ samples or IQ prediction errors over the transmission network.
