Abstract Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node via a source cell, a medium access control (MAC) control element (MAC-CE) triggering a handover from the source cell to a target cell in an activated cell set configured for Layer 1/Layer 2 (L1/L2) mobility. The UE may transmit, to the network node via the target cell, a physical random access channel (PRACH) to initiate an aperiodic contention-free random access (CFRA) procedure in the target cell in a random access channel (RACH) occasion in a PRACH slot associated with a slot offset indication received from the network node. Numerous other aspects are described.
