  • DEMODULATION REFERENCE SIGNALING IN LTE/NR COEXISTENCE
    Publication number: 20240039677
    Abstract: There is disclosed a method of operating a network node, the network node operating according to a first radio access technology, RAT. The method includes transmitting signaling having communication signaling and Demodulation Reference Signaling, DMRS, in a transmission resource pattern. The DMRS is arranged in the transmission resource pattern according to a DMRS pattern, in which the DMRS pattern is selected from a set of DMRS patterns based on a coexistence indication indicating the presence of cell-specific reference signals, CRS, associated to a second RAT.
    Type: Application
