Abstract: In this disclosure, methods and apparatus for managing interference are disclosed. In one example, the first station receives the first signal from the base station. The first station acquires information on a specific processing scheme of a second station for processing the first signal to be transmitted to a third station at the second station. The first station receives a second signal from the base station while the second station transmits the first signal to the third station. Here, since the first station has knowledge on the first signal and the information on the specific processing scheme, it can manage interference caused by the first signal from the second station.

Abstract: A method and device for transmitting data symbols using an antenna correlation in a wireless access system supporting multiple input/multiple output (MIMO) operations. The method includes: receiving, from a receiving end, grouping information of a plurality of antennas for supporting the MIMO operations, where the grouping information includes information on the two selected antenna subgroups; selecting two antennas of which a correlation is highest from the two selected antenna subgroups respectively for transmitting the data symbols; and transmitting different data symbols through each of the two selected antennas of the two selected antenna subgroups on an identical time frequency resource. Here, antennas with a highest correlation are grouped into two or more antenna subgroups. Also, two antenna subgroups, of which a correlation is lowest from the two or more antenna subgroups, are selected among the two or more antenna subgroups by the receiving end.
