A resource configuration method and apparatus are provided. In an example implementation, the method includes: receiving, by a terminal, indication information, where the indication information indicates a subcarrier width used for a first control channel, a maximum quantity of symbols occupied by the first control channel is determined based on the subcarrier width, and the different subcarrier widths correspond to different maximum symbol quantities; and determining, by the terminal based on the indication information, a quantity of symbols occupied by the first control channel, where the quantity of symbols occupied by the first control channel is less than or equal to the maximum quantity of symbols.
