1. A method of operating a network node in a radio access network, the method comprising:
transmitting reference signaling based on a reference signaling configuration, the reference signaling configuration corresponding to a comb-n structure for a symbol group of a slot, and the reference signaling configuration corresponding to at least one of a staggered and a re-ordered comb-n structure for one or more other symbol groups of the slot; and
the reference signaling configuration further comprising one or both of:
a symbol group having a length of m in symbols, wherein one of m=1 and m=2; and
a staggered comb-n structure corresponding to a frequency distribution over a symbol group shifted by k subcarriers for each shift in time corresponding to a length of the symbol group, wherein k is one of k=1, k=2, k=−1, k=−2, k=7, k=−7, k=14 and k=−14.
