Abstract: A communication method and apparatus, which relate to the technical field of communications, and can make a 20MHz discrete bandwidth obtained after splitting conform to a spectrum template of a bandwidth greater than 20MHz, such that the communication performance is improved when a distributed resource unit (DRU) is scheduled and transmitted within a bandwidth greater than 20MHz on the basis of the 20MHz discrete bandwidth. The method comprises: within a 20MHz discrete bandwidth in a first bandwidth, transmitting an orthogonal frequency division multiplexing (OFDM) symbol by means of a DRU, wherein a sub-carrier index of the DRU in the 20MHz discrete bandwidth is obtained by means of adding a-x to a sub-carrier index of a DRU in a 20MHz bandwidth, a being the number of guard sub- carriers on a first side of the first bandwidth, and x being the number of guard sub-carriers on a first side of the 20MHz bandwidth; or, the sub-carrier index of the DRU in the 20MHz discrete bandwidth is obtained by means of subtracting b-y from the sub-carrier index of the DRU in the 20MHz bandwidth, b being the number of guard sub-carriers on a second side of the first bandwidth, and y being the number of guard sub-carriers on a second side of the 20MHz bandwidth; and a, x, b and y are all positive integers. The present application is applicable to a wireless local area network that supports related standards of the Institute of Electrical and Electronics Engineers.
