1. A User Equipment (UE), comprising:
one or more non-transitory computer-readable media having computer-executable instructions embodied thereon; and
at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to:
receive a configuration of a first Bandwidth Part (BWP) through Radio Resource Control (RRC) signaling from a Base Station (BS);
initiate a Random Access (RA) procedure on the first BWP;
receive, while the RA procedure is ongoing on the first BWP, Downlink Control Information (DCI) indicating a BWP switching from the first BWP to a second BWP; and
determine whether to switch to the second BWP in response to receiving the DO;
in a case that the UE determines to switch to the second BWP:
stop the RA procedure that is ongoing on the first BWP,
determine, after stopping the RA procedure, whether the second BWP is configured with an RA resource, and
initiate, after determining that the second BWP is not configured with the RA resource, a new RA procedure on an initial BWP, the UE being informed of the initial BWP via system information received from the BS; and
in a case that the UE determines not to switch to the second BWP:
continue with the RA procedure that is ongoing on the first BWP.
