Abstract: A method, system and device for allocating resources of a base station node (Node B) are disclosed to enable F-DPCH resources of a local cell to be sufficiently used. In this invention, Node B reports to the RNC the F-DPCH capability of the local cell so as to provide a decision-making basis about using or not using the F-DPCH to the RNC. If the local cell supports F-DPCH, when the UE initiates an RRC connection establishment request, the RNC instructs the Node B to distribute the F-DPCH and HSDPA resources to the UE, otherwise the RNC instructs the Node B to distribute DPDCH and DPDCCH resources to the UE. The F-DPCH capability of the local cell can be reported in a newly added IE or extended existing IE of the Audit Response message and Resource Status Indication message.

The method includes: obtaining subframe information of each of multiple cells, where the subframe information of each of the multiple cells includes subframe configuration information and flexible subframe resource requirement information of each cell; and determining a flexible subframe resource configuration of each cell according to the subframe information of each of the multiple cells, where the flexible subframe resource configuration of each cell includes that each cell uses one or more of N flexible subframes to perform data transmission. A flexible subframe resource requirement of each of multiple neighboring cells is obtained, and flexible subframe resource configurations of the cells are coordinated in a distributed manner according to a subframe configuration and the flexible subframe resource requirement of each cell, thus, cross-subframe interference that may exist between flexible subframes can be reduced.
