    摘要: A method for efficiently transmitting and receiving data in a wireless access system and a pilot allocation structure for the same are provided. In the method, data is transmitted using a resource block constructed taking into consideration channel estimation capabilities and data transfer rate and data is received using the resource block. The resource block includes a predetermined number of pilot symbols constructed in a predetermined pattern and the pilot symbols are allocated to the resource block at a predetermined allocation rate taking into consideration the number of transmit antennas.
