Abstract: This application provides a communication method for a wireless fidelity Wi-Fi system and an apparatus, and relates to the field of communication technologies, to improve an anti-interference capability of an IoT device, and improve a coverage capability and a wall penetration capability. The communication method for a wireless fidelity Wi-Fi system includes: generating a Wi-Fi frame including a preamble, where a synchronization sequence of the preamble includes at least one extension code, and the extension code includes N symbols generated based on a Barker code, where N=α*M, M is a chip length of the Barker code, and α is a positive integer; and transmitting the Wi-Fi frame.

Abstract: Embodiments of this application provide an encoding method and apparatus, to improve an encoding gain in an RCM. The method includes: performing bit mapping on krv1 information source bits whose reliability is lower than a first threshold in a first bit sequence, to obtain a second bit sequence, where the first bit sequence is a bit sequence obtained by performing bit mapping after cyclic redundancy check CRC bits are added to an information source bit sequence, the krv1 information source bits are bits in the information source bit sequence, and a length of the first bit sequence is equal to a length of the second bit sequence; performing an exclusive OR operation on bits in a bit sequence obtained by encoding the first bit sequence and bits in a bit sequence obtained by encoding the second bit sequence, to obtain a third bit sequence; or encoding the second bit sequence, to obtain a third bit sequence; and mapping, to an orthogonal frequency-division multiplexing OFDM symbol, the third bit sequence and the bit sequence obtained by encoding the first bit sequence.
