A communication method includes: generating an extremely high-throughput physical layer protocol data unit (EHT PPDU) that comprises a legacy physical layer preamble and a new physical layer preamble, wherein the legacy physical layer preamble comprises a legacy short training field (L-STF), a legacy long training field (L-LTF), a legacy signal (L-SIG) field in turn, and a first field of the new physical layer preamble is a repeat of a field in the legacy physical layer preamble and is modulated by binary phase shift keying (BPSK); and sending the PPDU.

Communication method, communication apparatus, and communication device

A method of wireless communication includes receiving, at a communication device, an interrupt indication indicating an interruption to occur on a first transmission resource, interrupting, based on the interrupt indication, a transmission scheduled to occur using a second transmission resource on a channel, where the first transmission resource and the second transmission resource at least partially overlap, and transmitting, in case that the transmission included a control information, the control information, using a third transmission resource.

Control information transmission techniques

A low-density parity-check (LDPC) code encoding method and a communication apparatus are described that provide increased redundant bits through retransmission in an IR-HARQ mechanism, so as to decrease a channel coding rate, and improve decoding performance of an LDPC code. A check matrix of the LDPC code is used as a basic matrix, and the basic matrix is extended to obtain a mother matrix compatible with a plurality of code rates. During LDPC encoding, a transmit device reads, from the mother matrix, a check matrix corresponding to a required code rate, and performs LDPC encoding on an information bit sequence based on the read check matrix. LDPC encoding is performed on the information bit sequence by using check matrices of different sizes, to obtain different quantities of redundant bits.

LDPC code encoding method and communication apparatus

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.
