Data transmission method, data receiving method, and communication apparatus

Abstract

A data transmission method, a data receiving method, and a communication apparatus, which may be applied to an extended reality (XR) service or another low-latency service. The method includes: obtaining K to-be-coded data packets with a same length; performing shift exclusive OR coding based on a coding coefficient and the K to-be-coded data packets, to obtain a check packet; and sending the check packet, where a packet header of the check packet does not include indication information of the coding coefficient, the coding coefficient of the check packet is related to a difference between a data length of the check packet and the length of the to-be-coded data packet, and the to-be-coded data packet includes an original packet or a system packet corresponding to an original packet.
