1. An apparatus, comprising:
a processor configured to cause a wireless device to:
establish wireless links according to a first radio access technology (RAT) and a second RAT;
determine to perform transmit and receive blanking for one or more antennas of the wireless device for the first RAT to perform sounding reference signal (SRS) transmissions for the second RAT based at least in part on a band combination for the wireless links established according to the first RAT and the second RAT;
determine a modification to channel state feedback (CSF) reporting for the first RAT based at least in part on the transmit and receive blanking for one or more antennas of the wireless device for the first RAT to perform SRS transmissions for the second RAT; and
perform CSF reporting using the determined modification, wherein the modification includes:
determining a rank indicator to report for the wireless link established according to the first RAT, wherein the rank indicator is determined based at least in part on a SRS period for the second RAT; and
transmitting CSF for the wireless link according to the first RAT, wherein the CSF includes the determined rank indicator.
