1. A communication method applied in a wireless local area network, wherein the method comprises:
generating, by a communication apparatus, a physical layer protocol data unit (PPDU), wherein a transmission bandwidth of the PPDU is divided into a plurality of segments, the PPDU comprises multiple universal signal (U-SIG) fields and multiple extremely high throughput-signal (EHT-SIG) fields, wherein the multiple U-SIG fields and the multiple EHT-SIG fields are carried on more than one segment of the plurality of segments, the entire transmission bandwidth of the PPDU is used for single-user (SU) transmission or multi-user multiple-input multiple-output (MU-MIMO) transmission in non-OFDMA transmission, each of the multiple U-SIG fields indicates a number of EHT-SIG symbols, numbers of EHT-SIG symbols indicated by the multiple U-SIG fields are the same in the more than one segment of the plurality of segments, and each of the multiple EHT-SIG fields comprises a field indicating a number of MU-MIMO users, wherein each of the multiple U-SIG fields further comprises a compression field, the compression field indicates a compression mode, and each of the multiple EHT-SIG fields does not include a resource unit allocation subfield; and
sending, by the communication apparatus, the PPDU to a station.
