AI summary

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive channel state information (CSI) report configuration information indicative of a computational resource counting configuration associated with processing time domain (TD) CSI associated with a CSI-reference signal (CSI-RS) burst configuration, wherein the CSI-RS burst configuration corresponds to at least one burst of CSI-reference signal (CSI-RS) occasions. The UE may transmit a CSI report based at least in part on the CSI report configuration. Numerous other aspects are described.
