Abstract:
1. A resource allocation method, comprising: according to a quantity of resource blocks in a common resource area of a carrier and a set first corresponding relationship, determining a first resource block group size corresponding to a first resource allocation type in the common resource area, wherein the first corresponding relationship is a corresponding relationship between the quantity of the resource blocks and a resource block group size, wherein the carrier comprises the common resource area and a dedicated resource area, wherein the common resource area is a resource area that can be used by both a terminal of a communication system of a first type and a terminal of a communication system of a second type within the carrier, and the dedicated resource area is a resource area that can be used only by the terminal of the communication system of the second type within the carrier, and wherein the communication system of the second type is an evolved system of the communication system of the first type, and wherein resource group sizes for terminals of the communication systems of the first and second types in the common resource area are both equal to the first resource block group size; according to the first resource block group size, dividing all the resource blocks in the common resource area of the carrier into one or more first resource block groups; determining a first quantity of bits in a resource allocation field for the common resource area according to a quantity of resource blocks in the common resource area of the carrier and the first resource block group size, wherein the first quantity of bits indicates a quantity of resource block groups in the common resource area; determining a second quantity of bits in a resource allocation field for the dedicated resource area according to the first quantity of bits and a total quantity of bits in the resource allocation field corresponding to the first resource allocation type, wherein the second quantity of bits indicates a quantity of resource block groups in the dedicated resource area; determining a second resource block group size corresponding to the first resource allocation type in the dedicated resource area, according to a quantity of resource blocks in the dedicated resource area and the second quantity of bits, wherein a resource group size for terminals of the communication systems of the second type in the dedicated resource area is equal to the second resource block group size; according to the second resource block group size, dividing resource blocks in the dedicated resource area of the carrier into one or more second resource block groups, wherein each one of the one or more second resource block groups divided from the dedicated resource area corresponds to an indication for indicating whether a second resource block group is to be scheduled to a user equipment, and sending the indication to the user equipment.
