Abstract: Embodiments of the present invention provide a variable bandwidth-based communication method and an apparatus. The method includes: sending, by a network node, indication information to UE, where the indication information is used to indicate a target bandwidth parameter used by a serving cell corresponding to the UE; and communicating, by the network node, with the UE based on the target bandwidth parameter, where the target bandwidth parameter includes at least one of a target bandwidth, a target center frequency, and an enablement time of the target bandwidth. In this way, the network node can communicate with the UE in a changed bandwidth, so as to avoid a case in which communication is still performed in a relatively high bandwidth when a network load is relatively low, and reduce device power consumption.
