Abstract: This application provides a communication method and apparatus, to resolve a problem that retransmitted MPDUs with different RVs cannot be transmitted in a same transmission process, and improve data transmission efficiency. The communication method and apparatus may be applied to a data retransmission process between any two nodes in a Wi-Fi system. The method includes: When a PPDU sent by a first node includes one or more retransmitted MPDUs, the first node may include, in the PPDU, RV indication information used to indicate an RV of each retransmitted MPDU, so that a second node receives each retransmitted MPDU based on the RV indication information.

Abstract: A transmit end sends a physical layer protocol data unit (PPDU) to a receive end, where a bandwidth of the PPDU is P×10 MHz. The PPDU includes a first part of fields and a second part of fields. A quantity of tones per 10-MHz tone distribution corresponding to the first part of fields is 64, and a tone spacing is 156.25 kHz. A quantity of tones per 10-MHz tone distribution corresponding to the second part of fields is 128, and a tone spacing is 78.125 kHz. The corresponding method is applicable to 10 MHz, 20 MHz, 40 MHz, 60 MHz, so that a transmission bandwidth is increased compared with that of 802.11p, as well as a system throughput. The transmit end may transmit data by some RUs to increase a data transmission distance, or may simultaneously transmit data of different services by a plurality of RUs to improve data transmission efficiency.

Abstract: A communication method in a wireless local area network and a communication apparatus are provided. The method includes an access point generating a trigger frame, and sending the trigger frame to a station. The trigger frame includes resource allocation information and first indication information. The first indication information indicates a first bandwidth to the station, and the resource allocation information indicates a first distributed resource unit (RU) that is allocated to the station and that corresponds to the first bandwidth. The first bandwidth is a bandwidth of at least one sub-channel occupied by subcarriers included in the first distributed RU. According to the method, the station may determine a distributed bandwidth range of an allocated RU, for example, in a maximum bandwidth supported by the station, or in a bandwidth outside a punctured bandwidth, to increase a transmit power of the station.
