1. A method by a wireless device to extend communication range in a wireless network, comprising:
generating a physical layer protocol data unit (PPDU) that includes a preamble portion and a data portion that includes first data, the preamble portion comprising an extremely high throughput signal field (EHT-SIG) and a modulation and coding scheme (MCS) field implicitly indicating a PPDU duplicated in terms of resource units (RUs); and
transmitting the PPDU through the wireless network on a transmission channel that is subdivided into a plurality of RUs,
wherein the PPDU has a green field PPDU format formed by removing backwards compatible parts from an EHT PPDU format when an EHT wireless device operates in a 6 gigahertz (GHz) band.
