1. A method for receiving, by a user equipment, a downlink signal, the method comprising:
- receiving first information on a first cell set comprising a plurality of cells and on a plurality of parameter sets respectively corresponding to the plurality of cells;
receiving second information indicating a second cell set comprising at least one of the plurality of cells;
receiving third information indicating a specific cell in the second cell set; and
receiving the downlink signal through the specific cell using a parameter set of the specific cell among the plurality of parameter sets based on the third information.

Abstract
The base station of the present invention notifies a user device of a first set of cells and a set of parameters corresponding respectively to the cells of the first set of cells, and notifies the user device of a second set of cells that is a subset of the first set of cells and that is associated with the user device. The user device may receive a downlink signal or transmit an uplink signal by sing one of the sets of parameters associated with the second set of cells.
