US 12,615,101 B2 · Communication method for wireless fidelity Wi-Fi system and apparatus

Abstract

In the field of communication technologies, a communication method for a wireless fidelity (Wi-Fi) system and an apparatus provide improved performance of demodulating a Wi-Fi frame by the apparatus. The communication method for the wireless fidelity (Wi-Fi) system includes: generating a Wi-Fi frame including a first preamble field, where the first preamble field indicates a modulation and coding scheme MCS of at least one symbol in a data field in the Wi-Fi frame, an MCS order of first m symbols in the at least one symbol is less than an MCS order of another symbol, and m is a positive integer greater than or equal to 1; and transmitting the Wi-Fi frame.

A communication method for a wireless fidelity (Wi-Fi) system, the communication method comprising:

generating a Wi-Fi frame comprising a preamble field and a data field including a plurality of orthogonal frequency division multiplexing (OFDM) symbols, wherein the preamble field indicates a modulation and coding scheme (MCS) of at least one symbol of the plurality of OFDM symbols in the data field in the Wi-Fi frame, a MCS order of first m symbol(s) at a beginning of the data field including the plurality of OFDM symbols is less than a MCS order of another symbol in the data field including the plurality of OFDM symbols after the first m symbol(s), and m is a positive integer greater than or equal to 1;
and
transmitting the Wi-Fi frame.

A communication method for a wireless fidelity (Wi-Fi) system, the communication method comprising:

receiving a Wi-Fi frame transmitted by a communication apparatus, the Wi-Fi frame including a preamble field and a data field including a plurality of orthogonal frequency division multiplexing (OFDM) symbols;
determining, based on the preamble field in the Wi-Fi frame, a modulation and coding scheme (MCS) of at least one symbol of the plurality of OFDM symbols in the data field in the Wi-Fi frame transmitted by the communication apparatus, wherein a MCS order of first m symbol(s) at a beginning of the data field including the plurality of OFDM symbols is less than a MCS order of another symbol in the data field including the plurality of symbols after the first m symbol(s), and m is a positive integer greater than or equal to 1;
and
demodulating the at least one symbol based on the MCS.
