METHOD AND APPARATUS FOR CONTROLLING DATA TRAFFIC IN A TDD SYSTEM THAT USES MULTI-COMPONENT CARRIERS

WIPO Patent Application WO/2012/177042

A3

The present description relates to a method and apparatus for controlling data traffic in a time-division duplex (TDD) system that uses multi-component carriers. The method for controlling data traffic in a TDD system that uses multi-component carriers according to one embodiment of the present invention comprises the steps of: a base station transmitting, to a user terminal, a wireless signal including data from one or more component carriers from among a component carrier group including a first element carrier which is a primary cell (PCell) and a second element carrier (SCell) which is a secondary cell, wherein the primary cell and the secondary cell consist of uplink and downlink subframes in a time division duplex system; and the base station receiving, from the user terminal, a wireless signal including response control information for the data through the second component carrier. The second component carrier has a band different from that of the first component carrier. The second component carrier has a TDD set-up different from that of the first component carrier in the configuration of the downlink and uplink subframes. An uplink subframe which is different from the uplink subframe of the first component carrier exists in the second component carrier.
