Abstract
There is disclosed a method of operating a network node in a radio access network, the method including 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, wherein the reference signaling configuration corresponds to a staggered and/or re-ordered comb-n structure for one or more other symbol groups of the slot. The disclosure also pertains to related devices and methods.

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.
A network node for a radio access network, the network node configured to:
