receiving, from a base station (BS), the common signaling configured for the band based on the reception mode,
wherein the common signaling is further configured for at least one other band within the bandwidth of the carrier, and
wherein a bandwidth of the band and a bandwidth of the at least one other band is smaller than the bandwidth of the carrier.
