Original Abstract Submitted

The invention includes receiving, by a user equipment (UE), a configuration message indicating one or more frequency bands for transmitting a radio signal and determining, by the UE, a subset of the one or more frequency bands; the UE then performs a listen before talk (LBT) operation on each frequency band of the subset of the one or more frequency bands and the UE transmits a radio signal in at least one of the frequency bands of the subset. The transmitting can include transmitting at least one of a random access request, an information data signal or a control signal. The determining can includes determining a bandwidth part (BWP) in the frequency bands of the subset, wherein the BWP spans across at least one of the frequency bands of the subset. The UE can select the BWP for the transmission of the radio signal.
