Abstract:
1. A transmission apparatus of a mobile communication system, the transmission apparatus comprising: a scheduler for determining a first transmission power for a pilot channel and a second transmission power for a control channel, the second transmission power being determined in every transmission time interval; a pilot channel transmitter for transmitting, to a reception apparatus, a pilot signal by using the first transmission power in the pilot channel; a control channel transmitter for transmitting, to the reception apparatus, at least one control signal including control information by using the second transmission power in the control channel; and a control channel transmission power information transmitter for transmitting, to the reception apparatus, information about the second transmission power in the every transmission time interval, wherein the information about the second transmission power is a ratio of the second transmission power to the first transmission power, wherein the information about the second transmission power is used to regenerate the at least one control signal for data channel estimation in the reception apparatus, and wherein the at least one control signal is regenerated by performing the same coding process as a coding process used for the transmission apparatus to transmit the at least one control signal.
