Embodiments of the invention disclose a method and an apparatus for allocating a resource, and a communications system, so as to flexibly allocate a resource block for each user equipment. The method comprises: allocating at least one group of first resource blocks with a size of S1 for a first user equipment, and allocating at least one group of second resource blocks with a size of S2 for a second user equipment; and separately assigning the first resource blocks with the size of S1 and the second resource blocks with the size of S2 for the first user equipment and the second user equipment. In one aspect, in the method provided in the embodiments of the present invention, resource blocks specially for one or more user equipments are separately allocated for different user equipments in different channel environments according to an actual application scenario, therefore, receiving performance of a user equipment side can be optimized; and in another aspect, by separately assigning the allocated resource blocks to different user equipments, overhead of control signaling of a system is reduced, and valuable resources can be saved for the system. |
