Abstract

A method for wireless communication, a transmitter, and a receiver are provided. The method includes the following. A transmitter transmits a first ultra-high reliability (UHR) extended long range (ELR) physical layer protocol data unit (PPDU). The first UHR ELR PPDU at least includes a legacy short training field (L-STF), a legacy long training field (L-LTF), a legacy signal (L-SIG) field, a repeated L-SIG (RL-SIG) field, a universal signal (U-SIG) field, a UHR-STF, a UHR-LTF, a data field, and a packet extension (PE) field, where the data field is transmitted at a granularity of a first frequency-domain resource unit with N times duplication in a bandwidth of the first UHR ELR PPDU, and N equals to 4.
