Abstract: An apparatus for determining a time domain window, a terminal, and a readable storage medium. The method for determining a time domain window in embodiments of this application includes: determining, by a terminal, a second time domain window in a first time domain window based on first information. The terminal maintains a first transmission characteristic in the second time domain window for target uplink channel repetitions. The first information includes power control information used for each target uplink channel transmission in the target uplink channel repetitions. The first time domain window is a nominal time domain window configured by a network-side device. The first transmission characteristic is a transmission characteristic with consistent power and continuous phase.
