Abstract: Embodiments of this application provide a resource mapping method and apparatus, applied to the field of short-range communication. The method includes: determining a first mapping mode in a plurality of mapping modes, where the plurality of mapping modes further include a second mapping mode; and mapping, according to the first mapping mode, a first modulation symbol sequence carried in a first time unit, A plurality of modulation symbols in the first modulation symbol sequence are mapped to a plurality of subcarriers according to the first mapping mode. Each of the plurality of modulation symbols is mapped to a respective subcarrier in the plurality of subcarriers. The first mapping mode and the second mapping mode represent different mapping locations of the plurality of modulation symbols on the plurality of subcarriers.
