METHOD FOR TRANSMITTING/RECEIVING DATA IN A WIRELESS ACCESS SYSTEM AND BASE STATION FOR SAME

摘要

The present invention relates to a method for transmitting/receiving data in a Time Division Duplex (TDD) wireless access system supporting multiple cells, and a base station for same. In more detail, on the basis of a multi-cell TDD uplink-downlink configuration,the method includes confirming whether a collision subframe occurs, which is caused when an uplink subframe of a first cell and a downlink subframe of a second cell exist in the same time interval; and performing cross cell scheduling on the second cell through the first cell according to a TDD uplink-downlink configuration of the first cell. When data transmission is scheduled in the collision subframe by cross cell scheduling, by changing the transmission position of an uplink or a downlink according to the cross cell scheduling, the scheduled data are transmitted in the collision subframe.
