Method of transmitting and receiving pilot signal in a system with Multiple Input Multiple Output

摘要

The present invention discloses an efficient data transmission and reception method in a wireless access system and a pilot allocation structure therefor. The method may include transmitting data using a resource block configured in consideration of a channel estimation performance and a data rate, and receiving data using a resource block. At this time, the resource block includes pilot symbols composed of a predetermined number and a predetermined pattern.;Resource block, pilot symbol, OFDM symbol, subcarrier
