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.
