Abstract:
The present invention relates to a method in which a signal is transmitted between a base station and a terminal in a multi-antenna wireless communication system. The method transmits pre-estimated channel information to the terminal when the terminal moves to a specific position when channel estimation for a specific position is performed. As for the terminal which moves along a fixed route or the route of which can be estimated, the position of the terminal in the near future can be easily detected. Therefore, the transception of channel information can be performed in a more efficient manner in consideration of the above-described special environment.
