ABSTRACT:
A power spectral density of a pilot symbol and a data symbol is controlled for an uplink transmission by a mobile station in a wireless network by determining a power spectral density of at least one of the data symbol and the pilot symbol based on a peak-to-average ratio (PAR) of at least one of the data symbol and the pilot symbol. A power spectral density of at least one of the data symbol and the pilot symbol is then dynamically adjusted based on a difference between the PAR of the data symbol and a PAR of the pilot symbol. Changes in the power spectral densities of the pilot symbol and the data symbol are signaled to a receiving side of the uplink transmission. If acceptable by the receiving side, the pilot symbol and the data symbol are transmitted to the receiving side of the uplink transmission.
