7. A user equipment (UE) comprising:
one or more processors; and
one or more memories storing computer-readable instructions that, upon execution by the one or more processors, configure the UE to:
receive, from a network while the UE is connected to a serving cell, a transmission configuration indicator (TCI) state switch command associated with a neighbor cell;
determine a TCI state switch condition associated with the neighbor cell, the TCI state switch condition indicating at least one of:
whether a state of the neighbor cell is known or unknown to the UE, or
whether a TCI state of the neighbor cell is known or unknown to the UE; and
complete a switch to the TCI state of the neighbor cell within a first period of time or a second period of time based on at least the TCI state switch condition.
