This application discloses a measurement method for a terminal device, including: receiving measurement configuration information; and measuring, in m measurement windows in a measurement gap based on the measurement configuration information, m groups of to-be-measured signals sent by a network device. Correspondingly, this application also describes a measurement configuration method, a terminal device, and a network device. According to an example implementation, the terminal device discontinuously performs measurement in the measurement windows in the measurement gap, and transmits data by using an interval between the measurement windows, to implement discontinuous measurement in the measurement gap, and further reduce a data transmission delay.
