Abstract
The present specification relates to a method by which a terminal transmits channel information to a base station in an inter-vehicle communication system. The method for transmitting channel information can comprise the steps of: measuring channel information and feeding the same back to the base station; and receiving data on the basis of the channel information. The terminal comprises a plurality of distributed antenna units (DU), and when it is possible to select whether to activate each of the plurality of DUs, a plurality of channel information sets are measured according to the number and the location of activated DUs, and the channel information to be fed back can include the plurality of channel information sets.
