Methods, systems, and devices for wireless communications are described. In some cases, a wireless device such as a user equipment (UE) may receive a downlink transmission from a base station over a wireless channel, select, based on the received downlink transmission, a channel state information (CSI) computation mode for the wireless channel, where the CSI computation mode is based on an effective isotropic radiated power (EIRP) constraint, measure a set of one or more CSI reference signals (CSI-RSs) from the base station to obtain a CSI measurement, and transmit a CSI report to the base station based on the selected CSI computation mode and the CSI measurement.
