FIELD: information technology.
SUBSTANCE: power spectral density of a pilot symbol or data symbol is controlled for transmission over an uplink of a mobile station in a wireless network by determining power spectral density of at least one data symbol and pilot symbol based on the peak-to-average ratio (PAR) of at least one data symbol and pilot symbol. The power spectral density of at least one data symbol and pilot symbol is then dynamically controlled based on the difference between the PAR of the data symbol and PAR of the pilot symbol. The pilot symbol and data symbol signal the receiving side of the uplink transmission on changes in the power spectral density. If acceptable for the receiving side, the pilot symbol and data symbol are transmitted to the receiving side of the uplink transmission.
EFFECT: evaluation of a direct communication line from a return communication line, which enables an access point to extract the amplification coefficient for creating the directional pattern for transmission over the direct communication line when multiple antennae are available at the access point.
