A method for mapping resources of broadcast control channel is disclosed. Available subcarriers of a subframe in which the broadcast control channel is located are divided into three subcarrier sets, each of which is mapped to be one frequency partition, so that the subframe in which the broadcast control channel is located includes N frequency partitions, and resources of each frequency partition are mapped to be logical resource units, wherein N can be 1 or 3. With this method, subcarrier sets of the broadcast control channel are divided, and the resources of the broadcast control channel are mapped.

A resource mapping method is provided, in which a wireless communication system maps subcarriers to resource units through external permutation and internal permutation, the external permutation comprises: performing the first permutation on n physical resource units in every N1 physical resource units, orderly selecting n1×N1 physical resource units from the n physical resource units obtained from the first permutation, and then performing the second permutation on the remaining n−n1×N1 physical resource units in every N2 physical resource units, wherein n, N1, and N2 are all integers greater than or equal to 1, and N1 is not equal to N2, and n1 is an integer greater than or equal to 0. Frequency selectivity gain and frequency diversity gain may be achieved through the present invention by enabling a base station to select a proper resource scheduling granularity and resource unit types, thereby improving the spectrum efficiency of the future wireless communication system.
