Abstract: Embodiments of this disclosure provide a measurement method, a terminal device, and a network device. The measurement method includes: receiving a measurement adjustment related parameter configured by a network device; and adjusting a radio resource management RRM measurement mode based on the measurement adjustment related parameter. According to the embodiments of this disclosure, effective switching or adjustment between different RRM measurement modes can be implemented, and a ping-pong effect of measurement is avoided, while power consumption of the terminal device is reduced. This prevents the terminal device from frequently adjusting the configuration of RRM measurement, and ensures configuration flexibility of the network device.
