Abstract: This application discloses a method including a transmit end that generates and sends a physical layer protocol data unit (PPDU), and a receive end that receives the PPDU and parses the PPDU. An enhanced directional multi-gigabit (EDMG) modulation field in the PPDU includes a channel estimation field (CEF), the CEF includes a CEF sequence, and a length of the CEF sequence is m, where m is determined based on a quantity of bonding channels and a quantity of subcarriers included on a channel. When a discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-S-OFDM) technology is introduced into a 60 GHz WLAN standard, an applied CEF sequence included in a CEF can be determined, and DFT-S-OFDM transmission is further performed by using the CEF sequence. In this way, a PAPR of a WLAN system can be reduced while frequency division multiplexing for a plurality of users is supported.

Abstract: A convolutional code rate matching method and a communication apparatus are provided. A puncturing pattern of a second codeword at a second code rate is obtained based on a puncturing pattern of a first codeword at a first code rate. A second puncturing location set of the second codeword is a subset of a first puncturing location set of the first codeword. When a transmit device decreases a code rate from the first code rate to the second code rate, a redundant bit is sent at a location of a complementary set of the second puncturing location set relative to the first puncturing location set. Compared with the first puncturing location set, the second puncturing location set may obtain more incremental redundant bits, to decrease a channel encoding rate. This can improve decoding performance of a convolutional code.
