Abstract: A message transmission method and device relating to the field of communications technologies are described that improve an anti-interference capability in message transmission. The method includes generating a scrambling code according to a scrambling code initialization seed, wherein the scrambling code initialization seed meets the following expression: cinit=R·2a7+P·(nf mod k+1)·2b7 and then scrambling a message according to the scrambling code. The method further includes sending the scrambled message to a terminal on a physical downlink shared channel. Because the first time parameter has different values at at least two different moments, scrambling codes determined at the at least two corresponding different moments are different. Therefore, a possibility at which the base station uses a same scrambling code to scramble a same system message repeatedly in a time period is reduced, so that an anti-interference capability in system message transmission is improved.

Abstract: The signal transmitting method includes that a transmit end modulates a first frequency band that corresponds to a first signal to be transmitted by the single carrier system onto a second frequency band that corresponds to a second signal to be transmitted by the multicarrier system, to obtain a transmit signal including at least the first signal and/or the second signal. A spacing between a center frequency of a first subchannel and a center frequency of a second subchannel is an integer multiple of a spacing between two adjacent second subchannels. A signal bandwidth that corresponds to the first subchannel is less than or equal to a signal bandwidth that corresponds to the second subchannel. The method includes transmitting the transmit signal to a receive end for completing reception of the first signal and the second signal.
