Random access with bandwidth part switch

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code,
• wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to perform a process, the process comprising:
• trigger a random access procedure;
• switch from a first uplink bandwidth part that does not support a random access channel to a second uplink bandwidth part that has the random access channel configured after the triggering of the random access procedure, wherein the switching is autonomously performed by the apparatus;
• and
• perform the random access procedure using the second uplink bandwidth part.

A computer program product comprising a non-transitory computer-readable medium bearing computer program code embodied therein for use with a computer, the computer program code comprising:

• code for triggering a random access procedure at a user equipment;
• code for switching at the user equipment from a first uplink bandwidth part that does not support a random access channel to a second uplink bandwidth part that has the random access channel configured after the triggering of the random access procedure, wherein the switching is autonomously performed by the user equipment;
• and
• code for performing the random access procedure at the user equipment using the random access channel configured at the second uplink bandwidth part.
