    Abstract: A modulation mode determining method and device for a communication system. The method includes steps: setting a modulation mode adjudging condition in the communication system in advance; calculating to determine a current code rate; determining the currently needed modulation mode based on the current code rate and the modulation mode adjudging condition which is set in advance. And the adjudging condition corresponds to a code rate. The device includes: a configuration save module, for calculating to determine the current code rate; a modulation mode choosing module, for determining the currently needed modulation mode based on the current code rate and the modulation mode adjudging condition which is set in advance. Using the method, structure complexity of up-link and down-link control channels in the communication system can be reduced, and communication capability of the control channels can be improved.
