FIELD: radio engineering, communication.
SUBSTANCE: in one aspect, power control (PC) is supported in several PC modes such as "up-down" PC mode and delete-based PC mode. One PC mode may be selected for use. Overhead may be sent to indicate the selected PC mode. If the "up-down" PC mode is selected, a base station assesses the quality of the received signal for the terminal and sends PC commands to instruct the terminal to adjust its transmission power. If the delete-based PC mode is selected, the base station sends delete indicators which indicate whether code words received from the terminal are deleted or not. In both PC modes, the terminal controls its transmission power based on a power control feedback (e.g. PC commands and/or delete indicators) in order to attain the desired level of efficiency (e.g. desired delete frequency for code words). Delete indicators may also be used for handover.
EFFECT: reduced noise and achieving high efficiency for all terminals.
