1. A processor of a base station configured to perform operations comprising:
determining a sounding reference signal (SRS) configuration, comprising:
a plurality of cyclic shifts for a comb 8 SRS;
a plurality of user equipment (UE) ports for transmitting the comb 8 SRS; and
a mapping of the plurality of cyclic shifts to the plurality of UE ports, when an SRS sequence length is an integer multiple of 6, the maximum number of the plurality of cyclic shifts is six cyclic shifts; and
generating, for transmission to the UE, the SRS configuration.
