1. An apparatus comprising:
at least one processor; and
at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
receive, from a network, a channel state information report configuration comprising one or more sub-configurations, wherein a sub-configuration of the one or more sub-configurations is associated with at least one channel state information reference signal antenna port subset, and wherein one or more channel state information reference signal antenna port subsets corresponding to the one or more sub-configurations are associated with a same channel state information reference signal resource or resource set;
determine, for a calculation of one or more channel state information quantities for the sub-configuration corresponding to or indicating the at least one channel state information reference signal antenna port subset, a hypothetical physical downlink shared channel by considering an antenna port restriction based on the at least one channel state information reference signal antenna port subset the sub-configuration corresponds to or indicates; and
calculate the one or more channel state information quantities for the sub-configuration, based on the formed hypothetical physical downlink shared channel.
