Abstract: Embodiments of this application disclose a message processing method and a device, and relate to the field of communication technologies. In this way, a network device can determine a DC location that is corresponding to communication when a plurality of BWPs are simultaneously activated. A specific solution is as follows: A network device receives a first message, where the first message includes a DC location of each of M bandwidth parts BWP that are configured by the network device for a terminal; and the network device determines a DC location of current communication based on DC locations of N activated BWPs in the M BWPs, where M is an integer greater than or equal to 2, and N is an integer greater than or equal to 2 and less than M.
