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.

Abstract: Embodiments of this application provide short-range wireless communication methods and apparatuses for increasing coverage area. In an implementation, a method includes: configuring, by a first device, a first orthogonal frequency division multiplexing (OFDM) symbol on a first time domain resource of a first event period and a second OFDM symbol on a second time domain resource of the first event period, wherein the first OFDM symbol is used to transmit data between the first device and a second device, and the second OFDM symbol is used to transmit control signaling between the first device and the second device. Sending, by the first device, data to the second device on the first OFDM symbol at a first power and control signaling to the second device on the second OFDM symbol at a second power, wherein the first power is different from the second power.

Abstract: A receiver module that is communicatively connected to a plurality of Wi-Fi receiver chains is disclosed. The receiver module is configured to selectively switch the states of a plurality of Wi-Fi receiver chains between an “ON” state and an “OFF” state based on a signal quality parameter measured by each of these receiver chains.
