1. A method of operating a receiving radio node in a wireless communication network, the method comprising:
performing channel estimation based on received signaling, the channel estimation providing a channel estimate value for each subcarrier of a set of subcarriers;
the received signaling covering a number NPRB of Physical Resource Blocks, PRB, in frequency domain, each PRB having a number NSC of subcarriers;
the set of subcarriers comprising a number NSUB of subsets of subcarriers, subcarriers of the same subset being associated to the same PRB of the number NPRB of PRBs; and
the channel estimation associating different channel estimate values to different subcarriers of one or more of the NSUB subsets such that all of the NSC subcarriers of each PRB are associated with one of the different channel estimate values, and such that all the subcarriers of a same NSUB subset of the NSUB subsets are associated to a same channel estimate value of the different channel estimate values.
