Abstract
It is provided a method for reducing bit rate requirement over an uplink fronthaul link. The method is performed in a fronthaul transmitter of a radio network node and comprises the steps of: determining a group of frequency-domain resource elements having been received over a wireless channel (); estimating channel information (); reducing a number of bits for representing the respective frequency-domain resource element, to thereby obtain a modified resource element (); transmitting the modified resource elements of the group over the fronthaul link to a fronthaul receiver (); and transmitting compression metadata (), indicating how the reduction was performed, over the fronthaul link to the fronthaul receiver which performs the steps of receiving the modified resource elements (), receiving the compression metadata () and expanding the resource elements to increase the number of bits for representing the frequency-domain resource elements ().
