Abstract: A communication method, including receiving, by user equipment (UE), information about one or more backhaul links that is broadcast by different micro base stations, selecting, by the UE, a micro base station corresponding to backhaul link information that meets a preset condition, and accessing, by the UE, the selected micro base station when the selected micro base station is in an active state, or when the selected micro base station is in an inactive state, sending, by the UE, an activation signal to the selected micro base station, and accessing, by the UE, the selected micro base station after the micro base station is activated. Hence, a backhaul link can be used appropriately.

Abstract: An interference indication method and apparatus are presented. After detecting interference from a neighboring cell, a base station sends interference indication information to the neighboring cell, where the interference indication information includes at least indication information of a frequency resource that receives the interference from the neighboring cell and that is configured to be in a flexible half-duplex mode, so as to indicate that the interference from the neighboring cell is interference on the frequency resource configured to be in the flexible half-duplex mode. In this way, in an application scenario of a flexible half-duplex technology, a base station can learn of a status of interference from a neighboring cell, so as to use a corresponding interference suppression mechanism.
