1. A device comprising:
at least one processor; and
at least one memory including computer program codes;
the at least one memory and the computer program codes are configured to, with the at least one processor, cause the device at least to:
determine, at a terminal device, whether continuous Listen-Before-Talk (LBT) failures occur on a first bandwidth part (BWP), the terminal device operating on the first BWP; and
in response to the continuous LBT failures occurring on the first BWP;
determine a plurality of BWPs each configured with at least one of the following: a resource for performing a scheduling request (SR) procedure, and a resource for performing a random access procedure,
select a second BWP different from the first BWP to be switched to from among the plurality of BWPs,
switch to the selected second BWP different from the first BWP, and operate on the determined and selected second BWP.
