Document Type and Number:
WIPO Patent Application WO/2021/203353
Kind Code:
A1
Abstract:
Disclosed by the present application is a multicast transmission method, the multicast transmission method comprising: a first network device receives a first data packet and first indication information, the first indication information being used to indicate the order of the first data packet in at least one data packet; the first network device sets a first protocol layer sequence number of the first data packet according to the first indication information; and the first network device transmits the first data packet to a terminal device. In the foregoing manner, the data packet received by the terminal device comprises the corresponding first protocol layer sequence number, so that the terminal device may accordingly process the data packets received thereby according to the first protocol layer sequence number in the event of duplication, disorder, packet loss or incorrect reception of data packets received by the terminal device, thereby improving the communication efficiency.
