A device and method for controlling communication on a reverse link in a mobile communication system includes a measurer, a controller, and a reverse link transmitter according to an embodiment of the present invention. The measurer detects a power control bit from a channel signal received on a forward link and measures the reception strength of the channel signal using the detected power control bit. The controller compares the reception strength with a threshold and generates a signal for controlling transmission on a reverse link if the channel status of the forward link is determined to be bad during the comparison. The reverse link transmitter stops channel transmission on the reverse link in response to the transmission control signal.
