Title:
METHOD AND APPARATUS FOR AGGREGATING PLURALITY OF CELLS
Document Type and Number:
WIPO Patent Application WO/2014/069790
Kind Code:
A1
Abstract:
According to one embodiment of the present invention, disclosed is a method for aggregating a plurality of cells. The method for aggregating the plurality of cells may comprise a step of a first cell determining whether to add one or a plurality of second cells for user equipment, wherein a max number of cells to be aggregated can be determined depending on the number of cells set to a specific time division duplex (TDD) UL-DL setting as a reference setting from among first cell and the one or the plurality of second cells, and on the actual number of cells set to the specific TDD UL-DL setting. The method for aggregating the plurality of cells may comprise the steps of: the first cell transmitting a setting for adding the one or the plurality of second cells to the user equipment based on the maximum number of cells that are determined; and the first cell transmitting a signal for activating the one or the plurality of second cells to the user equipment.
