Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a channel state information (CSI) report configuration including configuration information that identifies a channel measurement resource associated with a first numerology and configuration information that identifies an interference measurement resource associated with a second numerology that is different from the first numerology. The UE may perform a channel measurement on the channel measurement resource associated with the first numerology and an interference measurement on the interference measurement resource associated with the second numerology. The UE may transmit, to the base station, a CSI report based at least in part on the channel measurement and the interference measurement. Numerous other aspects are described.
