Title:
DEVICE AND METHOD FOR TRANSMITTING CONTROL INFORMATION FOR INTER-HETEROGENEOUS CELL INTERFERENCE ADJUSTMENT IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/138087
Kind Code:
A2
Abstract:
The present invention relates to a device and method for transmitting control information for inter-heterogeneous cell interference adjustment in a wireless communication system. The present invention relates to a base station including: a signal receiving unit for receiving an ABS pattern; a system information generating unit for generating separation information that notifies the separated distance from a first sub frame transmitting PDCCH on the basis of the ABS pattern to a second sub frame transmitting PDSCH scheduled by the PDCCH; a downlink control information generating unit for generating downlink control information including a scheduling offset which indicates the separated distance; and a signal transmitting unit for transmitting the downlink control information from the first sub frame and transmitting a paging message or system information from the second sub frame. According to the present invention, when a TDM or FDM system is used in order to control the interference between heterogeneous cells, a terminal in an RRC idle state can easily receive a paging message and system information of an aggressor cell or victim cell.
