1. A method comprising:
triggering a random access procedure at a user equipment to which a first uplink bandwidth part and a second uplink bandwidth part are configured in a cell,
wherein the first uplink bandwidth part does not support a random access channel for the random access procedure and the second uplink bandwidth part supports the random access channel for the random access procedure;
switching at the user equipment from the first uplink bandwidth part to the second uplink bandwidth part after the triggering of the random access procedure, wherein the switching is autonomously performed by the user equipment, and wherein the switching comprises the user equipment autonomously deactivating the first uplink bandwidth part and activating the second uplink bandwidth part; and
performing the random access procedure at the user equipment using the random access channel configured at the second uplink bandwidth part.
