Embodiment Construction

[0035] Hereinafter, the present invention will be applied based on 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) or 3GPP LTE Advanced (LTE-A). This is just an example, and the present invention can be applied to various wireless communication systems. Hereinafter, LTE includes LTE and / or LTE-A.

[0036] Technical terms used herein are used only to describe specific embodiments and should not be construed as limiting the present invention. In addition, technical terms used herein should be interpreted as having meanings commonly understood by those skilled in the art and not being too broad or too narrow unless otherwise expressly specified. In addition, technical terms used herein, which are determined not to accurately express the spirit of the present invention, should be replaced by or understood by such technical terms that can be accurately understood by those skilled in the art. Also, the general terms used herein should be interpreted in the cont...

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.

Description

technical field [0001] The present invention relates to a wireless communication, and more particularly, to a method and an apparatus for aggregating multiple cells in a wireless communication system. Background technique [0002] 3GPP (3rd Generation Partnership Project) LTE (Long Term Evolution) is a progression of UMTS (Universal Mobile Telecommunications System), introduced with 3GPP Release 8. In 3GPP LTE, OFDMA (Orthogonal Frequency Division Multiple Access) is used for downlink, and SC-FDMA (Single Carrier Frequency Division Multiple Access) is used for uplink. 3GPP LTE employs MIMO (Multiple Input Multiple Output) with up to 4 antennas. Recently, discussion of 3GPP LTE-A (LTE-Advanced), which is an evolution of 3GPP LTE, is underway. [0003] As proposed in 3GPP TS 36.211V10.4.0, physical channels in 3GPP LTE can be classified into data channels such as PDSCH (Physical Downlink Shared Channel) and PUSCH (Physical and Uplink Shared Channel) and channels such as Con...
