1. An apparatus, comprising:
at least one processor; and
at least one memory comprising computer program code,
the at least one memory and computer program code configured, with the at least one processor, to cause the apparatus at least to
receive at least one reporting configuration from a network, wherein the reporting configuration is based on at least one of channel state information reference signals, CSI-RS, resource, or synchronization signal/physical broadcast channel, SS/PBCH, blocks, and wherein the reporting configuration includes information about an association between the at least one CSI-RS resource and the at least one SS/PBCH block;
determine whether an SS/PBCH block is associated with at least one configured CSI-RS resource;
in response to the determination that the SS/PBCH block is associated with at least one configured CSI-RS resource, determine whether the associated CSI-RS resource is sufficiently detected;
and
in response to the determination that the SS/PBCH block is not associated with at least one configured CSI-RS resource, or the determination that the associated CSI-RS resource is not sufficiently detected, transmit at least one measurement report that is based on the SS/PBCH block measurement when and as specified by the at least one reporting configuration, wherein a CSI-RS resource is sufficiently detected if its measurement is above a certain threshold provided in the at least one reporting configuration.
