Certain aspects of the present disclosure relate to methods and apparatus for generating and communicating reference signals. Certain aspects provide a method for communicating reference signals. The method includes selecting a reference sequence of a plurality of reference sequences to transmit in a cell in a synchronization signal block (SSB) based at least on a logical value, wherein the logical value is determined based on a SSB index indicating a location of the SSB within a set of resources of a plurality of sets of resources and at least one of a cell ID of the cell, a set index indicating a location of the set of resources within the plurality of sets of resources, or a second value based on system information corresponding to the cell; and transmitting the selected reference sequence in the SSB.
