Claim 14:
15. The network node of claim 1, wherein the processing circuitry is further configured to cause the network node to:
configure Tracking Reference Signal, TRS, resources in the RB of the cell by, for each TRS symbol in the RB, dividing a plurality of subcarriers into at least four sets of subcarriers, each of the at least four sets of subcarriers corresponding to a TRS power level that is different from a TRS power level of the other of the at least four sets of subcarriers; and
wherein the at least four sets of subcarriers comprise:
a first set of subcarriers that is assigned for transmitting TRS at a regular TRS power level;
a second set of subcarriers that is assigned for transmitting TRS at a power level that is 3 decibels, dB, higher than the regular TRS power level;
a third set of subcarriers that is assigned for transmitting TRS at a power level that is 4.8 dB higher than the regular TRS power level; and
a fourth set of subcarriers that is assigned for transmitting TRS at a power level that is 6 dB higher than the regular TRS power level.
