Embodiments of the present invention provide a scheduling method, device, and system, which are used in a communication system of multiple cells, where each cell in the multiple cells corresponds to a real scheduler, and the centralized virtual scheduler includes a determination unit for determining The transmission power of the first cell, where the first cell is each cell in the plurality of cells in the communication system; an interface unit configured to send the determining unit to a real scheduler corresponding to the first cell to determine The transmit power is used to instruct the real scheduler corresponding to the first cell to schedule the user equipment in the first cell using the transmit power determined by the determining unit. Therefore, using the hierarchical scheduling architecture of the present invention, the centralized virtual scheduler at the upper layer coordinates the transmission power among multiple cells as a whole, so as to instruct the real scheduler at the lower layer to schedule UEs with the coordinated transmission power. It can reduce inter-cell interference and improve network performance as a whole.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of communications, and more specifically, to a scheduling method, device and system. Background technique [0002] With the respective development of mobile communication and broadband wireless access technology, the services of the two penetrate each other. In order to meet the needs of mobile communication broadband and meet the challenges of broadband communication mobility, mobile communication technology introduces LTE (LongTerm Evolution, long-term evolution) communication system. [0003] In the LTE communication system, due to the adoption of OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) technology, each sub-channel is orthogonal to each other, thereby better solving the problem of interference in the cell. However, the LTE system has high requirements on spectrum utilization. Therefore, a co-frequency networking method is int...
