Abstract:
Various communication systems may benefit from improved random access operations. For example, certain embodiments may benefit from improved random access in which multiple bandwidth parts are configured to a user equipment within one cell. A method, in certain embodiments, may include triggering a random access procedure at a user equipment. The method may also include 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. The switching may be autonomously performed by the user equipment. In addition, the method may include performing the random access procedure at the user equipment using the random access channel configured at the second uplink bandwidth part.
