Embodiments of the present invention provide a resource allocation method and apparatus. A central control node determines a target backhaul node for a normal small cell from M candidate backhaul nodes and communication link resource information between the normal small cell and the target backhaul node based on access link resource pre-occupation information of the normal small cell, link quality information between the normal small cell and each of the M candidate backhaul nodes, and available backhaul link resource information sent by the M candidate backhaul nodes.
