FIELD: communication.
SUBSTANCE: invention relates to a wireless communication system, and is intended to reduce downlink interference between cells in extended range in a wireless communication environment in which various sizes hierarchically structured cell.
EFFECT: invention discloses, in particular, a wireless device, comprising an information collection module for collecting information about position of frequency spectrum, which given necessary information is assigned in subframe of downlink transmitted by neighbouring base station information, and transmission control module virtual carrier for transmitting virtual data carrier in downlink subframe in current cell so that virtual carrier is not superimposed on position of frequency spectrum assigned for said required information, virtual carrier has a narrower bandwidth than donor stripe.
