<p>A Method of transmitting MBMS (Multimedia Broadcast Multicast System) data based on cell grouping, which includes: Coding and modulating the MBMS data; choosing dedicated scrambling codes of cell group; choosing dedicated scrambling codes of cell; scrambling the coded and modulated MBMS data with the dedicated scrambling codes of cell group, and adding reference signal scrambled with the dedicated scrambling codes of cell group and the dedicated scrambling codes of cell; transmitting the scrambled reference signal and MBMS data. Using the invention, user terminals could do the RF combination easily, or do the RF combination and soft combination at the same time, consequently to get the diversity gain.</p> |
