Abstract: Radio receiver devices and related methods and computer programs are disclosed. A radio signal including information bits is received at a radio receiver device. The radio receiver device determines log-likelihood ratios, LLRs, of the information bits. The determining of the LLRs is performed by applying an iterative neural network, NN, to a frequency domain representation of the received radio signal over a transmission time interval, TTI. The iterative NN includes a single processing block iteratively executable to process the frequency domain representation of the received radio signal. The iterative NN is configured to output estimates of the LLRs based on the processing results of the single processing block.

Abstract: According to an aspect, a method in the radio head comprises receiving a reference signal from a terminal device, and computing a channel estimate on the basis of the reference signal and transferring the channel estimate with a first precision level to the network node over a link between the radio head and the network node. The first precision level defines a first number of bits carrying the channel estimate, then the method determines to change the precision level and, in response to the determining, transfers the channel estimate or a further channel estimate with a second precision level to the network node. The second precision level defines a second number of bits carrying the channel estimate or the further channel estimate, the second number being different from the first number.
