Configuration and indication of resources for partial frequency sounding

A method for wireless communications at a base station, comprising:

• transmitting, to a user equipment (UE), an indication of a configuration identifying a set of time and frequency resources for the UE to use to transmit sounding reference signals, the set of time and frequency resources comprising a plurality of subsets of time and frequency resources, wherein each subset of time and frequency resources of the plurality of subsets of time and frequency resources is associated with a corresponding value of a plurality of values of a partial frequency parameter;
• transmitting control signaling indicating a value of the partial frequency parameter of the plurality of values;
• transmitting an indication of a length of a sounding reference signal, the length of the sounding reference signal based at least in part on the value of the partial frequency parameter;
• and
• receiving the sounding reference signal on a subset of time and frequency resources of the plurality of subsets of time and frequency resources that corresponds to the value of the partial frequency parameter indicated by the control signaling.
