1. An apparatus, comprising:
at least one processor; and
at least one non-transitory memory storing instructions, that when executed by the at least one processor, cause the apparatus at least to:
determine information of a list of ranges in a communication network where at least one closed access group cell may be found and where at least one mobile integrated access and backhaul cell may be found;
scan synchronization signal blocks for physical cell identifiers of a candidate cell that are found in both at least one system information block closed access group list or range and at least one system information block mobile integrated access and backhaul list or range;
based on the scanning, decode system information at the candidate cell to verify that the candidate cell is a mobile integrated access and backhaul cell and a closed access group cell; and
based on the decoding, enabling the apparatus to access the candidate cell for cell reselection.
