Embodiments of the present invention provide a base station, a network system, and a communication method. The base station includes: a control module, configured to connect to a control module of at least one other base station by using a first logical interface, and perform control plane interaction during inter-base station coordination; and a data processing module, connected to the control module, and configured to connect to a data processing module of the at least one other base station by using a second logical interface, and perform user plane interaction during the inter-base station coordination. The base station in this embodiment of the present invention is provided with the first logical interface and the second logical interface to respectively implement the control plane interaction and the user plane interaction between base stations, so that the inter-base station coordination can be implemented.
