Resource mapping method and resource mapping device of control channels in communication system

The invention discloses a resource mapping method and a resource mapping device of control channels in a communication system. The method includes that a resource mapping process of sub-frames of broadcast control channels is different from a resource mapping process of sub-frames of non-broadcast control channels; and the resource mapping process of the sub-frames of the non-broadcast control channels is indicated through control information of the broadcast control channels. According to the technical scheme, problems of where and how synchronizing channels and the broadcasting control channels occupying resources are solved; processes of identifying the broadcast control channels by terminals are simplified; and spectrum effectiveness of a wireless communication system based on the OFDMA (orthogonal frequency division multiple access) technology is guaranteed.
