Aspects relate to mechanisms for measuring the interference on the sidelink for use in calculating the channel quality indicator (CQI) in channel state information (CSI) reporting. Channel state information-interference measurement (CSI-IM) resources on which a sidelink device may measure the interference may be located outside of a bandwidth allocated for the transmission of a physical sidelink shared channel (PSSCH) and/or inside of the allocated bandwidth. The sidelink device may measure respective interference values on one or more CSI-IM resources, identify one or more CQI(s) based on the measured interference value(s) and transmit one or more CSI reports including the one or more CQIs to another sidelink device.
