1. An apparatus, comprising:
at least one processor; and
at least one memory comprising computer program code,
the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to
detect at least one synchronization signal;
determine, in response to detecting the synchronization signal, whether one or more predefined conditions of the apparatus have been met;
determine, when the one or more predefined conditions have been met, that at least one candidate puncturing pattern of physical resource blocks of a physical broadcast channel is assumed based on a synchronization raster point of the detected synchronization signal; and
receive the physical broadcast channel with the at least one candidate puncturing pattern of physical resource blocks of the physical broadcast channel,
wherein the one or more predefined conditions have been met comprises the apparatus operating in a predefined frequency range.
