The present invention discloses are a method, a user equipment, and a base station for generating a pilot sequence. The method includes: determining a first parameter used to generate a pilot sequence in a first parameter candidate set, where the first parameter candidate set includes at least two timeslot numbers of the following timeslot numbers: a timeslot number obtained after downlink synchronization, a predefined timeslot number, timeslot numbers in a second type pilot configuration parameter, a timeslot number obtained from a high layer notification, and a timeslot number obtained from a dynamic notification, where a second type pilot is different from a pilot corresponding to the pilot sequence; and generating the pilot sequence according to the first parameter.
