The method includes: receiving an uplink signal that is generated according to CP configuration information and is sent by a UE, where the CP configuration information is used to identify a mapping relationship between a TTI and a CP type that is used by the uplink signal; and determining, according to the CP configuration information, a CP type corresponding to a TTI of receiving the uplink signal, and processing the uplink signal according to the determined CP type. The UE can use different CP types in the case of different TTIs. Therefore, the technical solutions provided in embodiments of the present invention provide support for solving the uplink delay without introducing too large overhead.
