Abstract: Embodiments of the present disclosure relate to methods, apparatuses and computer readable storage media for channel state information (CSI) reporting. According to embodiments of the present disclosure, a first device receives from a second device a configuration for CSI reporting. The configuration comprises at least a block error rate target and an indication of a number of HARQ transmissions. The first device determines Channel Quality Indicator (CQI) based on the block error rate target and the number of HARQ transmissions indicated by the configuration and transmits a CSI report comprising the CQI to the second device. The solution enables CSI feedback that is suitable for spectrally efficient and reliable delivery of Point to Multipoint services while meeting the delay requirement, in particular in the context of NACK-only feedback on common feedback resources.
