Next the transmission power of the PRB pre-scheduling resource of U201 is adjusted, to guarantee the PRB pre-scheduling money of U201
The resource of serving cell C20 of PRB resource and U201 in source with the first transmission power level, the interfered cell C10 of U201
Resource is orthogonal, and guarantees, i.e. S all orthogonal with all interference ranges { C10, C20, C30 } and { C10, C20 } for including C20User U201∩
(SCell C10∪SCell C20)=Φ；And SUser U201∩ (SInterference range { C10, C20, C30 }∪SInterference range { C10, C20 })=Φ.
Due to not having PRB resource mutually to conflict, the resource collection of U201 is SUser U201={1,2,3,4}；In addition, right
The resource of interference range { C10, C20 } belonging to serving cell C20 and U201 belonging to U201 is updated, wherein cell C20
Resource collection be SCell C20={ 1,2,3,4 }, the resource collection of interference range { C10, C20 } are SInterference range { C10, C20 }={1,2,3,4}。
