摘要： The present application discloses an apparatus and a method for controlling a change of operation state of a cell and a base station including the apparatus. The apparatus includes: a state change determining unit, configured to determine the change of operation state to be performed by the cell to be controlled, the change of operation state comprising change from active state to sleep state; and a sleep mode determining unit, configured to determine a sleep mode for the cell to be controlled so that the cell to be controlled has a different sleep mode from its adjacent cells, when the state change determining unit determines to perform the change of operation state of the cell to be controlled.

摘要： There is provided a method and device in a wireless communication system, the method comprising: a cell information interacting step of interacting information about a first cell and a second cell having interference with each other between the first cell and the second cell to determine a source cell and a target cell among the first cell and the second cell, wherein the target cell performs synchronization with the source cell being a synchronization source; an initial synchronizing step of performing initial frame-level synchronization by the target cell with the source cell being the synchronization source; a synchronization information interacting step of interacting information about a synchronization subframe position between the source cell and the target cell to determine a synchronization subframe position configurable for both the source cell and the target cell; and a symbol-level synchronizing step of performing symbol-level synchronization between the source cell and the target cell according to the determined synchronization subframe position. According to the disclosure, it is possible to realize synchronization among cells belonging to different operators and/or adopting different synchronizing manners.
