Abstract: This application provides a communication method and apparatus, applicable to the fields such as NR and LTE, to accurately estimate a G channel or an r/R channel, so as to ensure that other subsequent channels can still be accurately estimated. The method includes: A first device receives a first reference signal and performs channel estimation based on the first reference signal. The first reference signal is a reference signal determined by a second device by performing spectrum shifting on a second reference signal, and a frequency of the first reference signal is different from a frequency of the second reference signal.

Abstract: An example methods is provided, for example performed by an example terminal device, and example apparatuses. An example method includes receiving, by a terminal device, configuration information of a bandwidth part (BWP) from a network device. The BWP comprises a first bandwidth and a second bandwidth. The first bandwidth is determined based on a radio frequency bandwidth of the terminal device. The second bandwidth is determined based on a baseband bandwidth of the terminal device. The example method further includes communicating, by the terminal device, with the network device by using the BWP.
