    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 one aspect of the present invention, a method for transmitting and receiving data in a wireless access system, the method including transmitting data using a resource block constructed taking into consideration channel estimation capabilities and data transfer rate, and receiving data using the resource block. Here, the resource block may have a 6×6 structure constructed with 6 OFDM symbols and 6 subcarriers, and one or more first pilot symbols may be allocated to prescribed OFDM symbols of a first subcarrier and a fifth subcarrier of the resource block. Moreover, the first pilot symbols may be allocated to the resource block at a predetermined allocation rate taking into consideration a number of transmit antennas.

    摘要: In the present invention, an uplink synchronization signal for measuring a location of a user device is assigned to a predetermined uplink sub-frame and a predetermined sub-band and is transmitted to one or adjacent cells as well as a serving cell in a predetermined period. Since the synchronization signal for measuring the location is transmitted to a plurality of cells through the same wireless resource, other date are not transmitted to the same wireless resource and a near-far effect can be reduced in each cell.
