Abstract: Embodiments of this application provide a method and an apparatus for setting a symbol in a communications system that uses a plurality of subcarrier spacings. The method includes: obtaining, by a terminal, a length of a reference blank symbol, where the length of the reference blank symbol is associated with a first subcarrier spacing, and the first subcarrier spacing is a minimum subcarrier spacing in the plurality of subcarrier spacings; and setting, by the terminal based on the length of the reference blank symbol and time domain information of the reference blank symbol, a blank symbol for a subcarrier corresponding to a second subcarrier spacing in the plurality of subcarrier spacings. According to the method and apparatus for setting a symbol provided in the embodiments of this application, when setting, based on the length of the reference symbol, a blank symbol in a subframe corresponding to a subcarrier used by the terminal, the terminal may set one or more complete symbols as blank symbols. This avoids a case in which a symbol cannot work normally because a part of the symbol is set as a blank symbol, thereby improving spectral efficiency of the system.
