1. A method for wireless communication at a transmitting device, comprising:
determining a pattern for a set of time-frequency resources that includes a plurality of symbols and a plurality of frequency tones, wherein:
the pattern comprises an assignment of reference signals used for positioning to a first set of frequency tones within a first symbol of the set of time-frequency resources and to a second set of frequency tones within a second symbol of the set of time-frequency resources, the first symbol and the second symbol being consecutive;
each frequency tone of the first set is separated in frequency from each frequency tone of the second set by at least one frequency tone of the plurality of frequency tones; and
the pattern is based at least in part on any of a set of sequences of offsets including: {0, 2, 1, 3} for a comb level of four, {0, 3, 1, 4, 2, 5} for a comb level of six, {0, 4, 2, 6, 1, 5, 3, 7} for a comb level of eight, or {0, 8, 4, 12, 2, 10, 6, 14, 1, 9, 5, 13, 3, 11, 7, 15} fora comb level of 16;
mapping the reference signals to a subset of the set of time-frequency resources based at least in part on the pattern; and
transmitting the reference signals via the subset of the set of time-frequency resources.
