METHOD AND APPARATUS FOR PROVIDING CONTROL INFORMATION
First Claim
1. A method of transmitting a control information, which is transmitted by a macro base station in a wireless communication system including the macro base station and a pico base station, the method comprising the steps of:
- transmitting an assignment information regarding a subframe of a 1st set, which is limited to transmit a downlink signal, to the pico base station;
transmitting an assignment information regarding a subframe of a 2nd set belonging to the subframe of the 1st set to the pico base station; and
transmitting a control information via the subframe of the 1st set,wherein the control information for the macro base station is transmitted in the subframe not corresponding to the subframe of the 2nd set among the subframe of the 1st set and wherein the control information for the pico base station is transmitted in the subframe corresponding to the subframe of the 2nd set among the subframe of the 1st set.

Abstract
The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and an apparatus for a macro base station transmitting control information, comprising the following steps: transmitting to a pico base station assignment information regarding a first set of subframes with limited downlink signal transmission; transmitting to the pico base station assignment information regarding a second set of subframes which belong to a first set of subframes; and transmitting the control information by means of the first set of subframes, wherein the control information for the macro base station is transmitted from subframes in the first set of subframes which do not belong to the second set of subframes, and the control information for the pico base station is transmitted from the subframes in the first set of subframes which belong to the second set of subframes.
