Abstract: Technical solutions provided in this application may be applied to an extended reality XR service or another low-latency service. In a multi-hop scenario, after receiving a data packet sent by a previous-hop node and an encoding coefficient of the data packet relative to an original data packet, a forwarding node first determines a newest encoding coefficient based on the encoding coefficient received by the forwarding node from the previous-hop node and an encoding coefficient newly obtained by the forwarding node, and encodes, by using the newest encoding coefficient, the data packet received by the forwarding node from the previous-hop node. In this case, a data packet obtained through encoding is essentially a data packet obtained by the forwarding node by encoding the original data packet by using the newly obtained encoding coefficient. An encoding calculation amount can be further reduced while network recoding is implemented, thereby improving an encoding rate.

Abstract: A communication method and apparatus, and a readable storage medium are provided. A network coding NC parameter corresponding to a received index is determined based on a correspondence between the index and an NC parameter, and the NC parameter is applied to NC processing. According to this application, NC processing can adapt to a channel quality state, so that transmission reliability can be ensured and spectrum utilization efficiency can be improved. This application may be applied to an extended reality XR service, a scenario with a low latency and/or a scenario with a large uplink capacity.

Abstract: Coding method and apparatus provide for coding a to-be-coded data unit to obtain a coded data unit, where a size of the to-be-coded data unit is related to a size of a first data unit. The first data unit is a transport block TB, a protocol data unit PDU, or a service data unit SDU. The first data unit is generated based on the coded data unit.
