Abstract: An information transmission method and a related device applied to a cloud service system are provided. The cloud service system includes an arbiter, a first switch, and a first server group. The arbiter is connected to the first server group by using the first switch. The method includes: a first server obtains a first identifier of the first server in the first server group. The first server determines, in a first slot, a first time domain location corresponding to the first identifier. The first time domain location is a time domain location at which the first switch receives a first request to be processed by the arbiter, and different identifiers correspond to different time domain locations in the first slot. The first server sends the first request to the first switch based on the first time domain location.

Abstract: A method and an apparatus for generating a standard cancellation signal includes: setting weight values according to frequency points of a current cell and its neighboring cells; according to the frequency points of the current cell and neighboring cells and the weight values of the frequency points, performing Fourier transform to obtain a corresponding time-domain signal; and performing highest amplitude normalization on the time-domain signal and performing a cyclic shift to obtain a standard cancellation signal. The embodiments generate a standard cancellation signal according to frequency points of the current cell and its neighboring cells, so that the current cell and its neighboring cells share the peak clipping noise, and therefore helping improve the peak clipping performance of the current cell or reduce the EVM distortion.
