Patent ID: 11438118

Abstract:
There is disclosed a method of operating a network node (100) in a NR radio access network, the method comprising transmitting demodulation reference signaling, DM-RS, associated to downlink channel signaling, the DM-RS having a DM-RS pattern in frequency domain over a range of subcarriers including a reference subcarrier, wherein in a first frequency range below the reference subcarrier, the DM-RS pattern comprises a first sub-pattern represented by a repeated flush arrangement of a pattern element covering a number NP of subcarriers, and in a second frequency range above the reference subcarrier, the DM-RS pattern comprises a second sub-pattern represented by a repeated flush arrangement of the pattern element, wherein the first sub-pattern and the second sub-pattern are separated in frequency domain by an interrupting pattern having a number NI of subcarriers, wherein NI>0 and NI is different from NP. The disclosure also pertains to related methods and devices.
