Abstract
A method for uplink transmission in an OFDMA system is provided. The subcarrier transmission method includes arranging 4 pilot REs at different positions of a frequency axis in a basic unit when the basic unit includes 4 subcarriers on the frequency axis and 6 OFDM(A) symbols in a time axis, arranging data REs at remaining positions of the basic unit, and transmitting the basic unit to a receiving end.

A method of transmitting a basic unit in uplink by a mobile station (MS) in an Orthogonal Frequency Division Multiple Access (OFDMA) wireless communication system, the method comprising:
- forming the basic unit which size is 4 subcarriers by 6 OFDMA symbols, the basic unit containing a plurality of pilot and data resource elements (REs);
- configuring the pilot REs for single antenna in the basic unit at intervals of 3 subcarriers in a frequency axis and at intervals of 1 or 4 OFDMA symbols in a time axis;
- and
- transmitting the basic unit in uplink,
- wherein the RE is a time-frequency resource defined by one OFDMA symbol and one subcarrier,
- wherein the pilot and data REs are configured in the basic unit as in Pattern Table 1 expressed as follows:
- PATTERN TABLE 1
