Abstract: Embodiments disclose a signal processing method and a network device, so as to number a transmission time interval (TTI) in a frame structure and generate a signal sequence by using a number of the TTI. The method includes: determining a number of a transmission time interval TTI in a frame structure, where the TTI includes a time length less than 1 millisecond; and generating a signal sequence of the TTI based on the number of the TTI. The number of the TTI less than 1 millisecond or equal to 1 millisecond in the frame structure is determined, and the signal sequence of the TTI is generated based on the number of the TTI. This prevents interference between adjacent or neighboring TTIs or intersymbol interference (ISI) from being generated due to generation and use of a same signal sequence because for all short TTIs.
