FIELD: communications.
SUBSTANCE: to achieve the effect, a radio network node, a wireless device, and related methods are described. In one aspect, when the first radio access technology and the second radio access technology coexist on the same carrier, the symbol location of the reference signals of the first radio access technology may move or change when the reference signals of the first radio access technology conflict with the reference signals of the second radio access technology.
EFFECT: elimination of channel estimation distortion for LTE or NR with respect to which reference signal the radio network node decides to perform decimation as it must choose to transmit either LTE CRS or NR DMRS in conflicting resource elements.
