Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a reduced capability (RedCap) may receive a blind handover initiation communication comprising a cell identifier (ID) associated with a target cell. The RedCap may perform a wireless communication operation associated with the target cell based on whether the cell ID is indicated in a first database, of the first database and a second database stored in a memory of the RedCap UE, the first database comprising RedCap-supporting cell information that includes at least one RedCap support indication associated with at least one cell that indicates that the at least one cell supports RedCap communications, and the second database comprising non-RedCap-supporting cell information that includes at least one non-RedCap support indication associated with at least one additional cell that indicates that the at least one additional cell does not support RedCap communications. Numerous other aspects are described.
