METHOD AND DEVICE FOR SELECTING ANTENNA IN MULTI-ANTENNA SYSTEM

摘要

Provided is a method for selecting an antenna performed by a receiver in a multi-antenna system. The method for selecting the antenna performed by the receiver in the multi-antenna system, comprises: a subcarrier group setting step for setting subcarrier groups by grouping subcarriers; a channel information acquisition step for acquiring channel information between a receiving end antenna and each of a plurality of transmission end antennas; an antenna selecting step for determining said subcarrier groups, which are to be transmitted to each of the plurality of said transmission end antennas on the basis of said channel information; and an antenna selection information transmission step for transmitting antenna selection information, which contains the result of said antenna selection, to a transmission end.
