METHOD FOR CONTROLLING POWER OF TRANSMISSION THROUGH INFORMATION CHANNEL OF DIRECT COMMUNICATION LINE Russian patent published in 2008 - IPC H04B7/185 H04B7/05 

Abstract RU 2320085 C2

FIELD: radio communication networks, in particular, methods and devices for controlling transmission power.

SUBSTANCE: in accordance to the method, power of transmission through direct communication line to a client terminal in composition of a radio communication system, which contains a set of rays, is controlled by means of determining baseline power level, Pbaseline, on basis of accepted effective signal to noise ratio (SNR) in control channel; marginal value of power, Pmargin, is determined on basis of detected sensitivity to interferences; and correction of power level, Pcorrection, is determined on basis of determined packet error coefficient (PER); and Ptransmit is set on basis of Pbaseline, Pmargin and Pcorrection. For example, Ptransmit may be set to power level which is essentially equal to a total of Pbaseline, Pmargin and Pcorrection. Each component, Pbaseline, Pmargin and Pcorrection, may be determined by means of independently acting check connection circuits or processes.

EFFECT: weakening of interferences with simultaneously economized transmission power, in particular in composition of systems with limited energy potentials.
