A resource processing method performed by a network system that comprises a relay node, RN, a Donor Evolved Node B, DeNB, a Un interface, and a Uu interface, the method comprising: determining, by the RN according to a preset policy, whether the DeNB is required to divide resources for the RN; informing, by the RN, the DeNB of the determination result as to whether the DeNB is required to divide resources for the RN; determining, by the RN when a carrier aggregation, CA, function is enabled on the Un interface, whether the DeNB is required to divide resources for the RN for every frequency point; and determining, by the RN according to the preset policy, whether the DeNB is required to configure backhaul sub-frame information for the RN, wherein: informing by the RN the DeNB of the determination result as to whether the DeNB is required to divide resources for the RN comprises: determining, by the RN, the cell resource information the DeNB configures for the RN on the Un interface; and informing the DeNB by the RN of the determination result as to whether the DeNB is required to divide resources for the RN, as well as the cell resource information configured for the RN on the Un interface; determining by the RN the cell resource information the DeNB configures for the RN on the Un interface comprises: determining, by the RN, the cell resource information the DeNB configured for the RN on the Un interface in accordance with RN type, cell information which an operation and maintenance, OAM, of the RN configures for the RN and that is supported by the Un interface, and a donor cell list that can be introduced for the RN. determining, by the RN according to a preset policy, whether the DeNB is required to divide resources for the RN; informing, by the RN, the DeNB of the determination result as to whether the DeNB is required to divide resources for the RN; determining, by the RN when a carrier aggregation, CA, function is enabled on the Un interface, whether the DeNB is required to divide resources for the RN for every frequency point; and determining, by the RN according to the preset policy, whether the DeNB is required to configure backhaul sub-frame information for the RN, wherein: informing by the RN the DeNB of the determination result as to whether the DeNB is required to divide resources for the RN comprises: determining, by the RN, the cell resource information the DeNB configures for the RN on the Un interface; and informing the DeNB by the RN of the determination result as to whether the DeNB is required to divide resources for the RN, as well as the cell resource information configured for the RN on the Un interface; determining by the RN the cell resource information the DeNB configures for the RN on the Un interface comprises: determining, by the RN, the cell resource information the DeNB configured for the RN on the Un interface in accordance with RN type, cell information which an operation and maintenance, OAM, of the RN configures for the RN and that is supported by the Un interface, and a donor cell list that can be introduced for the RN. determining, by the RN, the cell resource information the DeNB configures for the RN on the Un interface; and informing the DeNB by the RN of the determination result as to whether the DeNB is required to divide resources for the RN, as well as the cell resource information configured for the RN on the Un interface; determining by the RN the cell resource information the DeNB configures for the RN on the Un interface comprises: determining, by the RN, the cell resource information the DeNB configured for the RN on the Un interface in accordance with RN type, cell information which an operation and maintenance, OAM, of the RN configures for the RN and that is supported by the Un interface, and a donor cell list that can be introduced for the RN.
