FIELD: radio engineering; wireless communication systems affording communication line quality feedback.
SUBSTANCE: remote-station device has quality measuring unit for iterative measurement of communication line quality and for quality metric evaluation, as well as differential analyzer for detecting changes in measured quality of communication line and for generating differential quality metric, the latter and differential quality metric being transferred to base station. Signals incorporating quality message and differential indicators are transferred to base station over feedback communication line; quality messages periodically provide direct communication line quality metric while differential indicators follow quality metric between sequential quality messages; differential indicators are used to update quality messages.
EFFECT: enhanced precision and speed of communication line quality feedback.
