A method for mapping resource units is disclosed. The method includes: dividing the physical resource unit set to obtain a first physical resource unit set which is in a unit of N1 continuous physical resource units, and a second physical resource unit set into which the remaining physical resource units are put; permuting, in a unit of N2 continuous physical resource units, the physical resource units in the second physical resource unit set; allocating, in a unit of N1 continuous physical resource units, the physical resource units in the first physical resource unit set to each frequency partition, and allocating, in a unit of one physical resource unit, the permuted physical resource units in the second physical resource unit set to each frequency partition. By using the invention, the combination of external mapping under the two-level sub-carrier mapping manner in the partial frequency multiplexing with the localized mapping and the distributed mapping can be realized.
