Abstract
A method for transmitting multimedia broadcast/multicast service includes: checking whether packet loss occurs during a transmission process of the multimedia broadcast/multicast service; and notifying, upon checking a packet loss, a physical layer not to transmit any data over a time and frequency resource used for transmitting the lost packet. A system for transmitting multimedia broadcast/multicast service is also provided. The method and system realizes checking and handling the packet loss during transmission process of MBMS service in time, effectively prevents errors from spreading, guarantees that terminals can receive MBMS service data correctly and further ensures smooth radio combining in the physical layer.
