Abstract
There is disclosed a method of operating a network node (100) in a radio access network, the method comprising transmitting signaling in a transmission timing structure, the signaling comprising demodulation reference signaling (DMRS), wherein the DMRS is transmitted on symbols of the transmission timing structure based on a DMRS pattern, the DMRS pattern being based on a pattern configuration indication set. The disclosure also pertains to related methods and devices.
