METHOD AND APPARATUS FOR GENERATING FEEDBACK IN A COMMUNICATION SYSTEM
First Claim
1. A method for generating feedback in a communication system, the method comprising:
- receiving information about first Evolved Node Bs (ENBs) and a threshold for the first ENBs, which are powered off at a specific time;
measuring a channel status for each of second ENBs, which are subject to channel status measurement;
selecting a third ENB having an optimal channel status from among the second ENBs, based on the measured channel statuses;
generating first feedback information including a cell index and channel status information for the third ENB;
measuring a channel status for each of the second ENBs, while the first ENBs are powered off;
selecting a fourth ENB having an optimal channel status from among the second ENBs, based on the measured channel statuses; and
generating second feedback information including a cell index and channel status information for the fourth ENB.

4. A method for receiving feedback in a communication system, the method comprising:
-
allocating resources for a signal for channel measurement for each of first Evolved Node Bs (ENBs) that transmit data to a User Equipment (UE) located at an edge of a first cell; determining a threshold for second ENBs that are powered off at a specific time; and transmitting, to the UE, the signal for channel measurement for each of the first ENBs, information about the second ENBs, and the threshold for the second ENBs. - View Dependent Claims (5)

6. An apparatus for generating feedback in a communication system, the apparatus comprising:
-
a communication unit that receives information about first Evolved Node Bs (ENBs) and a threshold for the first ENBs, which are powered off at a specific time; and a controller that measures a channel status for each of second ENBs, which are subject to channel status measurement, selects a third ENB having an optimal channel status from among the second ENBs, based on the measured channel statuses, generates first feedback information including a cell index and channel status information for the third ENB, measures a channel status for each of the second ENBs while the first ENBs are powered off, selects a fourth ENB having an optimal channel status from among the second ENBs, based on the measured channel statuses, and generates second feedback information including a cell index and channel status information for the fourth ENB. - View Dependent Claims (7, 8)
