The present application discloses a subband switching method, including: determining, by a network device, a target subband to which user equipment is to switch; sending, by the network device, identification information of the target subband to the user equipment; determining configuration information of the target subband according to the identification information of the target subband; and switching, by the user equipment, to the target subband according to the configuration information of the target subband. In the subband switching method provided in embodiments of the present application, switching between subbands can be implemented, so that when the UE has a subband switching requirement, the user equipment can be instructed to switch to a target subband. Therefore, service quality of the UE is improved.
