Abstract: Embodiments provide a data transmission method and a related device. Under the method, after determining a first data packet to be sent to a receive end, a transmit end may generate a second data packet based on the first data packet, encode the second data packet, and send an encoded second data packet. A length of the second data packet is greater than a length of the first data packet. In various embodiments, when sending a data packet to the receive end, the transmit end may generate a longer data packet from a shorter data packet through combination, and send the longer data packet to the receive end after channel coding. In this way, a relatively high channel coding gain can be obtained during data transmission, and a relatively high bit error rate of short packet transmission is avoided, so that data transmission reliability can be improved.

Abstract: A coding method, a wireless device, and a chip are described. A coding method may include obtaining, based on a sequence whose length is 2n′, a mother code sequence used for coding, where the sequence whose length is 2n′ includes 2n′ sequence numbers, a length of the mother code sequence is 2n, the mother code sequence includes 2n sequence numbers, the 2n sequence numbers are some or all of the 2n′ sequence numbers, n′ is a natural number, and n is a natural number less than or equal to n′. The method may also include coding an input to-be-coded bit by using the mother code sequence. According to this method, a system may store one or more long sequences, and then obtain a required mother code sequence from one of the long sequences according to a coding requirement, thereby reducing storage overheads of the system.

Abstract: A signal transmission method and a terminal, where a first terminal sets first information indicating a terminal type of the first terminal, and sends a signal including, the first information to a second terminal such that the second terminal identifies the terminal type of the first terminal based on the first information. The first information is set, and the signal including the first information is sent to the second terminal such that the second terminal identifies the terminal type of the first terminal based on the first information and processes the processed signal based on the terminal type of the first terminal to prevent, by distinguishing types of terminals, signal interference from being caused between different terminals.
