Abstract

Example methods for transmitting a physical layer protocol data unit (PPDU) and apparatus are described. One example method includes generating and transmitting a PPDU that includes a long training field (LTF). A length of a frequency-domain sequence of the LTF is greater than a first length, and the first length is a length of a frequency-domain sequence of an LTF of a first PPDU transmitted over a channel whose bandwidth is 160 MHz.
