1. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
receive, from a base station (BS), a channel state information reference signal (CSI-RS) communication;
transmit, to the BS, a physical uplink control channel (PUCCH) communication including feedback information that is a response to the CSI-RS communication and including an interference measurement, wherein the PUCCH communication includes an indication of a second sub-band and wherein the CSI-RS communication is received and the PUCCH communication is transmitted on a first sub-band, of a plurality of sub-bands;
switch, based at least in part on transmitting the PUCCH communication, from the first sub-band to the second sub-band; and
transmit, using the second sub-band, one or more sounding reference signal communications.
