Abstract: This application provides a communication method and device in a wireless local area network. The communication method includes: A receive end receives indication information from a transmit end, where a buffer of the receive end stores a log-likelihood ratio (LLR) corresponding to coded bits in an aggregated media access control protocol data unit (A-MPDU) subframe including a target media access control protocol data unit (MPDU). The receive end discards the LLR corresponding to the coded bits in the A-MPDU subframe including the target MPDU according to the indication information. According to the technical solutions provided in this application, the LLR corresponding to the coded bits in the buffer of the receive end can be discarded in time, thereby improving throughput of a system and reducing memory requirements.

Abstract: A station (STA)-side data acknowledgment apparatus includes a transceiver configured to send a data frame and send an acknowledgment request, and a processor configured to control the transceiver to send the acknowledgment request after a duration from an end of sending the data frame. The duration is greater than or equal to a transmission delay on a backhaul link between access points (APs). The acknowledgment request is an acknowledgment request for the data frame.

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: 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.

Abstract: This application provides methods and apparatuses for sending and receiving a physical layer protocol data unit. 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, for example, 2048, of a frequency domain sequence of a short training field that is transmitted over a 160 MHz-bandwidth channel; and sending the PPDU over a target channel, where a bandwidth of the target channel is greater than 160 MHz. According to embodiments of this application, a larger actual channel bandwidth can be achieved, and backward compatibility is implemented.
