Patent number: 10165583Abstract: A scheduling method, apparatus, and system are provided. The system includes at least one real scheduler and a centralized virtual scheduler. The centralized virtual scheduler is configured to determine transmit power of a first cell and send the transmit power determined by the determining unit to a real scheduler corresponding to the first cell, so as to instruct the real scheduler corresponding to the first cell to schedule UE in the first cell by using the transmit power determined by the centralized virtual scheduler. Therefore, by using a layered scheduling architecture according to the present application, an upper-layer centralized virtual scheduler instructs, by performing comprehensive coordination on transmit power of multiple cells, a lower-layer real scheduler to schedule UE by using the transmit power coordinated by the centralized virtual scheduler. This can reduce inter-cell interference and improve overall network performance.Type: GrantFiled: June 13, 2016Date of Patent: December 25, 2018Assignee: Huawei Technologies Co., Ltd.Inventor: Zhipeng Fang
