    • The present application discloses a method and system for transmitting a Broadcast/Multicast Service (MBMS), which is used for solving the problem that macro cell coverage of the MBMS and macro diversity combining of multi-cells cannot be implemented efficiently based on a frame structure of the existing Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system in prior art. The method includes: mapping a channel estimation code and data symbols of a Broadcast/Multicast Service to a resource unit, wherein the channel estimation code is mapped in front of the data symbols in a signal frame at a time slot for all services or a time slot for the MBMS; and transmitting the resource unit. Using the present application, efficiency and performance of transmitting a MBMS are improved, and the multi-cells combining of the MBMS and deployment of the MBMS with a macro cell mechanism are implemented efficiently.
