Abstract: A method and an apparatus for transmitting a physical layer protocol data unit that can provide a short training field sequence for a larger channel bandwidth. The short training field sequence has a smaller peak-to-average power ratio PAPR and better performance. The method includes: generating a physical layer protocol data unit PPDU, where the PPDU includes a short training field, a length of a frequency domain sequence of the short training field is greater than a first length, and the first length is a length of a frequency domain sequence of a short training field of a PPDU transmitted on a channel with a bandwidth of 160 MHz; and sending the PPDU on a target channel, where a bandwidth of the target channel is greater than 160 MHz.

Abstract: Embodiments of the present invention disclose a state switching method and apparatus. The state switching method includes: receiving, by a first network node, a preset frame sent by a second network node, where the preset frame includes indication information used to indicate an on/off state of a main transceiver and/or a wake up receiver of the first network node immediately, after a specified time point, or within a specified time period; and controlling, by the first network node based on the indication information, to switch an on/off state of the main transceiver and/or the wake up receiver of the first network node. According to the embodiments of the present invention, energy is saved by using a preset frame to indicate an on/off state of a main transceiver and/or a wake up receiver of a network node after a specified time point or within a specified time period.
