Abstract
This application provides a communication method, apparatus, and system. The communication method includes: a centralized unit receives a data packet sent in a multicast manner. The centralized unit generates a packet data convergence protocol (PDCP) data unit based on the data packet, where the PDCP data unit includes the data packet and a PDCP header. The centralized unit sends the PDCP data unit to a distributed unit. The distributed unit receives the PDCP data unit from the centralized unit, where the PDCP data unit includes the PDCP header, a synchronization protocol header, and a payload. The distributed unit generates a media access control (MAC) data unit, where the MAC data unit includes a MAC header, an RLC header, the PDCP header, and the payload.
