Channel state information (csi) computation for effective isotropic radiated power (eirp)-constrained transmissions

An apparatus for wireless communications at a user equipment (UE), comprising:

• a processor,
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive a downlink transmission from a base station over a wireless channel;
• select, based at least in part on the received downlink transmission, a channel state information (CSI) computation mode for the wireless channel, wherein the CSI computation mode is based at least in part 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 at least in part on the selected CSI computation mode and the CSI measurement.

A non-transitory computer-readable medium storing code for wireless communications at a user equipment (UE), the code comprising instructions executable by a processor to:

• receive a downlink transmission from a base station over a wireless channel;
• select, based at least in part on the received downlink transmission, a channel state information (CSI) computation mode for the wireless channel, wherein the CSI computation mode is based at least in part 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 at least in part on the selected CSI computation mode and the CSI measurement.
