Abstract: This application provides a communication method, an apparatus, a device, and a storage medium. The method includes: A first device generates a first orthogonal frequency division multiplexing (OFDM) time domain signal, which occupies one subcarrier in frequency domain and is used by a second device to perform backscatter communication. The first device sends the first OFDM time domain signal to the second device. The first OFDM time domain signal occupies one subcarrier in frequency domain, such that power is concentrated on the subcarrier. When the second device performs backscatter communication based on the first OFDM time domain signal, reliability of backscatter data is improved.

Abstract: A monitoring method and an apparatus are provided. The method includes transmitting, by a terminal device, first information based on a first repetition number, where the first repetition number is less than or equal to a second repetition number, and the second repetition number is a maximum repeat transmission number of the first information. The method also includes determining, by the terminal device, a scheduling end moment of the first information based on the second repetition number, where the scheduling end moment of the first information is a transmission end moment of the first information when the first information is transmitted based on the second repetition number. The method further includes starting or restarting, by the terminal device, a timer at the scheduling end moment of the first information, and monitoring a PDCCH search space before the timer expires or stops.

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·2α7+P·(nfmodk+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.
