Abstract
The present invention relates to a wireless communication system and, particularly, to a method and a device therefor, the method comprising the steps of: configuring a cell group including multiple Ucells; identifying subframe configuration information on a particular cell within the cell group; and configuring subframe transmission directions of cells within the cell group so as to be the same at the same time point, on the basis of the subframe configuration information on the particular cell, wherein the particular cell is one Ucell among the multiple Ucells within the cell group when the cell group includes only Ucells, and the particular cell is an Lcell when the cell group includes the Lcell.
Claims12
A method of performing communication by a user equipment (UE) in a wireless communication system, the method comprising:
- configuring a cell group including a plurality of unlicensed band cells (UCells);
- identifying subframe configuration information about a specific cell in the cell group;
- and
- configuring subframe transmission directions of cells in the cell group to be the same at the same timing, based on the subframe configuration information about the specific cell,
- wherein, if the cell group includes only the UCells, the specific cell is any one of the UCells in the cell group, and
- if the cell group includes a licensed band cell (LCell), the specific cell is the LCell.
A user equipment (UE) for performing communication in a wireless communication system, the UE comprising:
- a radio frequency (RF) module;
- and
- a processor,
- wherein the processor is configured to
- configure a cell group including a plurality of unlicensed band cells (UCells),
- identify subframe configuration information about a specific cell in the cell group, and
- configure subframe transmission directions of cells in the cell group to be the same at the same timing, based on the subframe configuration information about the specific cell, and
- wherein, if the cell group includes only the UCells, the specific cell is any one of the UCells in the cell group, and
- if the cell group includes a licensed band cell (LCell), the specific cell is the LCell.
