Abstract: A method for processing an uplink reference signal includes determining a current baseband processing payload, and processing each of N received uplink reference signals according to a preset first condition in response to the baseband processing payload being less than a first preset value or processing each uplink reference signal in a signal set according to a preset second condition in response to the baseband processing payload being greater than a second preset value. The second preset value is greater than or equal to the first preset value. The signal set includes one or more of the N uplink reference signals. A baseband processing payload corresponding to processing an uplink reference signal according to the preset second condition is less than a baseband processing payload corresponding to processing an uplink reference signal according to the preset first condition. N is a positive integer.
